Description

An automatic production line for packaging goods

Technical Field

The invention relates to the technical field of cargo packaging, in particular to an automatic production line for cargo packaging.

Background Art

At present, foam boxes are often used to hold and transport fresh food such as fruits and vegetables. The foam box generally includes a box body and a box cover. The fresh food is placed in the box body, and the top opening of the box body is closed with the box cover. Generally, tape is wrapped around the joint between the box body and the box cover for multiple turns to stabilize the box cover on the top of the box body, thereby achieving the packaging of the foam box.

In order to replace manual labor and improve the packaging efficiency of foam boxes, the prior art generally adopts a foam box packaging and packaging device to wrap tape around the joints of the foam boxes. However, the rotation of the installed tape roll is difficult to control, and the tape wrapped on the foam box has many wrinkles, making it difficult to tightly seal the joints of the foam box. The wrinkles of the tape are also not beautiful. When the packaging is stopped, the tape roll is likely to continue to rotate due to inertia and release excess tape, which requires manual intervention and affects the packaging efficiency of the foam boxes.

Summary of the invention

The technical problem to be solved by the present invention is to overcome the existing defects and provide an automatic production line for cargo packaging, so that the rotation of the tape roll is controlled, and the tape roll has a certain resistance when it rotates to release the tape, so that the tape can be tightly wrapped around the joints of the foam box to avoid wrinkles on the wrapped tape that affect the aesthetics of the packaging, and at the same time, it is also beneficial to tightly seal the joints of the foam box and protect the fresh goods in the foam box. When the packaging is stopped, there is resistance to the rotation of the tape roll, and the tape roll will not release excess tape due to inertia, thereby reducing manual intervention and helping to improve the packaging efficiency of the foam box. The efficiency of cargo packaging using the foam box is greatly improved, and the problems in the background technology can be effectively solved.

To achieve the above object, the present invention provides the following technical solution: an automatic production line for packaging goods, comprising a bottom plate, a bracket being arranged on the bottom plate, and further comprising:

The cargo roller conveyor mechanism comprises a roller conveyor assembly and two transverse rectangular tubes, the two transverse rectangular tubes are installed on the top of the bracket, the roller conveyor assembly is installed between the two transverse rectangular tubes, and a packaging gap is arranged in the middle area of the roller conveyor assembly;

The cargo clamping and rotating mechanism is installed on the bottom plate, and the cargo clamping and rotating mechanism is located directly below the packaging gap;

The cargo pressing mechanism is installed on the upper side of the middle part of the two horizontal rectangular tubes;

The packing tape lifting and swinging control mechanism is installed on the horizontal rectangular tube on the rear side, and the packing tape lifting and swinging control mechanism is located on the right side of the cargo pressing mechanism, and the packing tape lifting and swinging control mechanism is connected to the cargo pressing buffer swing arm mechanism, and the cargo pressing buffer swing arm mechanism is connected to the tape installation and attachment mechanism.

The two transverse rectangular tubes are used as the skeleton of the cargo roller conveyor mechanism for installing the roller conveyor assembly. The roller conveyor assembly conveys the foam box containing the cargo from left to right. When the middle of the foam box containing the cargo corresponds to the packaging gap, the cargo clamping and rotating mechanism lifts the foam box containing the cargo through the packaging gap to allow the bottom of the foam box to leave the roller conveyor assembly. Then the cargo pressing mechanism presses down the box cover of the foam box to allow the box body and the box cover of the foam box to fit closely. Then the packaging tape lifting and swinging control mechanism drives the cargo to close the buffer swing arm mechanism to swing clockwise. The cargo to close the buffer swing arm mechanism drives the tape installation and attachment mechanism to close the butt joint of the box body and the box cover in the foam box with a buffering force. The tape end of the tape roll installed on the tape installation and attachment mechanism is attached to the butt joint of the foam box. Then the cargo clamping and rotating mechanism drives the foam box to rotate counterclockwise, and the tape of the tape roll is pulled and released, and is wound around the butt joint of the foam box. It stops after winding a predetermined number of circles, and the packaging and sealing of the foam box can be completed.

Furthermore, the packing tape lifting and swinging control mechanism includes a packing tape lifting component, a support arm swinging component and a support arm. The packing tape lifting component is installed on the rear horizontal rectangular tube, and the support arm swinging component is installed on the packing tape lifting component. The support arm swinging component is connected to one end of the support arm. The packing tape lifting component is used to drive the support arm swinging component and the support arm to move up and down, so that the tape installed on the tape installation and attachment mechanism is aligned with the joint of the foam box. The support arm swinging component is used to drive the support arm to swing. When the support arm swinging component drives the support arm to swing clockwise, the goods are pressed against the buffer swing arm mechanism to allow the tape installation and attachment mechanism to have a buffering force and be pressed against the joint of the foam box. When the support arm swinging component drives the support arm to swing counterclockwise, the goods are pressed against the buffer swing arm mechanism to drive the tape installation and attachment mechanism away from the packaged and packaged foam box, so that the foam box can be smoothly transported to the left and right through the roller conveying component.

Furthermore, the cargo-closing buffer swing arm mechanism includes a supporting disc, an arc slide groove, an arc slide rod, a buffer spring, a fan-shaped slider, a buffer disc and a buffer cantilever.

The outer side of the clamping strip is fixedly connected to an attachment frame, and a vertical attachment rubber roller is rotatably connected to the attachment frame.

Furthermore, it also includes a tape cutting mechanism, which includes a cutting motor, a cutting rod, a knife seat and an arc blade. The cutting motor is installed at the top center of the shell cover, the output shaft at the top of the cutting motor is fixedly connected to one end of the cutting rod, and the other end of the cutting rod is fixedly connected to the top of the knife seat.

Furthermore, it also includes a belt tensioning and releasing mechanism, which includes a friction disc, an arc seat plate, an arc friction plate and a synchronous radially movable buffer control component. The bottom end of the bottom shaft is fixedly connected to the middle of the friction disc, and a synchronous radially movable buffer control component is installed at the bottom of the belt shell. Three arc seat plates are arranged on the synchronous radially movable buffer control component. The three arc seat plates are arranged at equal angles around the outer circumference of the friction disc, and an arc friction plate is detachably installed on the side of each arc seat plate close to the friction disc.

Further, the cargo clamping and rotating mechanism includes a pallet, a pallet lifting control component, a pallet rotating component and a cargo clamping component.

The pallet lifting control component is used to drive the pallet rotating component and the pallet to move up and down. When the pallet lifting control component drives the pallet rotating component and the pallet to descend, the pallet is located below the packaging gap and will not interfere with the foam box being transported from left to right on the roller conveyor component. When the middle of the foam box corresponds to the packaging gap, the pallet lifting control component drives the pallet rotating component and the pallet to rise, and the pallet lifts the bottom of the foam box away from the roller conveyor component. The cargo clamping components on both sides of the pallet clamp the bottom of both sides of the foam box, and the pallet rotating component drives the pallet and the foam box to rotate counterclockwise, so that the tape is pulled and wrapped around the joint of the foam box.

Furthermore, the cargo clamping mechanism includes a clamping power assembly, a mounting disc and a follow-up clamping turntable. The clamping power assembly is installed on the upper middle side of the two horizontal rectangular tubes. The clamping power assembly is connected to the top of the mounting disc. The bottom of the mounting disc is rotatably connected to the follow-up clamping turntable. The follow-up clamping turntable is located directly above the middle of the pallet.

Compared with the existing technology, the beneficial effects of this automatic cargo packaging production line are:

1. The packing tape lifting assembly is used to drive the support arm swing assembly and the support arm to move up and down, so that the tape installed on the tape installation and attachment mechanism is aligned with the joint of the foam box. The support arm swing assembly is used to drive the support arm to swing. When the support arm swing assembly drives the support arm to swing clockwise, the goods are pressed against the buffer swing arm mechanism to allow the tape installation and attachment mechanism to have a buffering force and be pressed against the joint of the foam box. When the support arm swing assembly drives the support arm to swing counterclockwise, the goods are pressed against the buffer swing arm mechanism to drive the tape installation and attachment mechanism away from the packaged and sealed foam box, so that the foam box can be smoothly transported to the left and right through the roller conveyor assembly.

2. The synchronous radial movable buffer control component allows the three arc seat plates and the arc friction plates to provide friction for the rotation of the friction disc in three directions, so that the friction disc is more evenly subjected to the friction in all directions. At this time, the rotation of the tape roll, the tape sleeve, the tape roll circular support plate and the bottom shaft has resistance. Since the rotation of the tape roll has resistance, the released tape can be tightened to the foam box, allowing the tape to be more smoothly attached to the joints of the foam box, thereby providing better protection for the fresh goods inside and making the foam box more beautiful after packaging.

3. The rotation of the tape roll is controlled. There is a certain resistance when the tape roll rotates to release the tape. Therefore, the tape can be tightly wrapped around the joint of the foam box to avoid wrinkles on the wrapped tape that affect the aesthetics of the packaging. At the same time, it is also beneficial to tightly seal the joint of the foam box and protect the fresh goods in the foam box. When the packaging is stopped, there is resistance to the rotation of the tape roll, and the tape roll will not release excess tape due to inertia, which reduces manual intervention and helps to improve the packaging efficiency of the foam box. The efficiency of packaging goods with foam boxes is greatly improved.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Embodiment 1, please refer to Figures 1 to 13, this embodiment provides a technical solution: an automatic production line for cargo packaging, comprising a bottom plate 1, a bracket 11 is arranged on the bottom plate 1, and also comprises a cargo roller conveying mechanism 2, a cargo clamping and rotating mechanism 4, a cargo pressing mechanism 5, a packing tape lifting and swinging control mechanism 6, a cargo clamping and buffering swing arm mechanism 7 and a tape installation and attachment mechanism 8;

The cargo roller conveyor mechanism 2 includes a roller conveyor assembly and two transverse rectangular tubes 21. The two transverse rectangular tubes 21 are installed on the top of the bracket 11. The roller conveyor assembly is installed between the two transverse rectangular tubes 21. A packaging gap is set in the middle area of the roller conveyor assembly.

The roller conveying assembly includes long conveying rollers 22 and short conveying rollers 23. A plurality of longitudinal long conveying rollers 22 are rotatably connected transversely and equidistantly between the left ends of the two transverse rectangular tubes 21, and a plurality of longitudinal long conveying rollers 22 are rotatably connected transversely and equidistantly between the right ends of the two transverse rectangular tubes 21. A plurality of longitudinal short conveying rollers 23 are rotatably connected transversely and equidistantly on the inner side of the middle part of each transverse rectangular tube 21. The area between the rear end of the front short conveying roller 23 and the front end of the rear short conveying roller 23 is the packaging gap. Specifically, there are at least three long conveying rollers 22 between the left ends of the two transverse rectangular tubes 21, at least three long conveying rollers 22 between the right ends of the two transverse rectangular tubes 21, and at least three short conveying rollers 23 in the middle part of each transverse rectangular tube 21.

The cargo roller conveyor mechanism 2 further includes a conveying power assembly, which is connected to the end of one of the long conveying rollers 22 .

Specifically, the conveying power assembly includes a reduction power motor 24, a sprocket 25, and a chain 26. The two ends of the conveying long roller 22 extend into the two horizontal rectangular tubes 21 respectively and are fixedly connected with the sprocket 25. The end of the conveying short roller 23 extends into the corresponding horizontal rectangular tube 21 and is fixedly connected with the sprocket 25. All the sprockets 25 in each horizontal rectangular tube 21 are connected by a chain 26. The end of one of the conveying long rollers 22 is connected to the output end of the reduction power motor 24. The reduction power motor 24 is installed on the horizontal rectangular tube 21. The reduction power motor 24 drives the conveying long roller 22 to rotate. The conveying long roller 22 can drive all the conveying long rollers 22 and the conveying short rollers 23 to rotate clockwise through the transmission of the chain 26 and the sprocket 25. The foam box is placed on the conveying long roller 22 on the left. Due to the synchronous and unidirectional rotation of the conveying long roller 22 and the conveying short roller 23, the foam box is conveyed from left to right.

The cargo clamping and rotating mechanism 4 is installed on the bottom plate 1, and the cargo clamping and rotating mechanism 4 is located directly below the packaging gap.

The cargo clamping and rotating mechanism 4 includes a pallet 48, a pallet lifting control component, a pallet rotating component and a cargo clamping component. The pallet lifting control component is installed at the position corresponding to the packaging gap on the bottom plate 1, the pallet lifting control component is installed on the top of the pallet rotating component, the pallet 48 is installed on the top of the pallet rotating component, and the cargo clamping components are respectively installed on the left and right ends of the pallet 48.

The pallet lifting control assembly includes a base 41, a telescopic rod 42, a lifting plate 43 and a lifting hydraulic cylinder 46. The base 41 is fixedly connected to the position of the bottom plate 1 corresponding to the packaging gap. The top four corners of the base 41 are fixedly connected to the four corners of the lifting plate 43 through four telescopic rods 42 respectively. The middle part of the base 41 is connected to the middle part of the lifting plate 43 through a vertical lifting hydraulic cylinder 46. The four telescopic rods 42 serve as guide limits, so that the lifting plate 43 can only move up and down relative to the base 41. The extension of the lifting hydraulic cylinder 46 can push the lifting plate 43 to move upward, and the shortening of the lifting hydraulic cylinder 46 can drive the lifting plate 43 to move downward.

The support plate rotating assembly includes an arch frame 44, a rotating motor 45 and a rotating shaft 47. The arch frame 44 is fixedly connected to the lifting plate 43. The middle part of the arch frame 44 is rotatably connected to a vertical rotating shaft 47 through a bearing. The top end of the rotating shaft 47 is fixedly connected to the bottom center of the support plate 48, and the bottom end of the rotating shaft 47 is fixedly connected to the output shaft of the rotating motor 45. The rotating motor 45 is installed on the lifting plate 43. When the rotating motor 45 works, it drives the rotating shaft 47 to rotate relative to the arch frame 44, thereby driving the support plate 48 to rotate. The support plate 48 lifts the foam box and can drive the foam box to rotate.

The cargo clamping assembly includes a transverse guide column 49, an electric telescopic rod 410 and a clamping plate 411. The middle of the left and right sides of the support plate 48 are respectively provided with electric telescopic rod mounting grooves, and the fixed ends of the two transverse electric telescopic rods 410 are respectively fixedly connected in the two electric telescopic rod mounting grooves. The telescopic ends of the two electric telescopic rods 410 are respectively fixedly connected to the bottom of the clamping plate 411, and the front and rear ends of the left and right sides of the support plate 48 are respectively provided with guide holes, and the transverse guide columns 49 are horizontally slidably connected in the guide holes. The ends of the transverse guide columns 49 are respectively fixedly connected to the bottom of the clamping plate 411. The two electric telescopic rods 410 are connected to the bottom of the corresponding clamping plate 411, and the cross guide column 49 and the guide hole cooperate to limit the movable direction of the clamping plate 411, so that the clamping plate 411 can only move left and right. The extension and retraction of the electric telescopic rod 410 can drive the clamping plate 411 to move left and right. The simultaneous shortening of the two electric telescopic rods 410 can make the two clamping plates 411 approach each other, and the foam box on the support plate 48 can be clamped. The simultaneous extension of the two electric telescopic rods 410 can make the two clamping plates 411 move away from each other, and the two sides of the foam box can be loosened.

Since the electric telescopic rod 410 rotates with the support plate 48, it is necessary to use a conductive slip ring to supply power to the electric telescopic rod 410 to avoid entanglement of the power supply line. The conductive slip ring is installed on the rotating shaft 47, and the conductive slip ring is installed on the arch frame 44 through a slip ring bracket. The conductive slip ring cooperates with the wire located inside the rotating shaft 47 and the support plate 48 to supply power to the electric telescopic rod 410 when the electric telescopic rod 410 rotates with the support plate 48, thereby controlling the extension and retraction of the electric telescopic rod 410. The specific installation and wire arrangement method adopts the existing technology.

The pallet lifting control assembly is used to drive the pallet rotating assembly and the pallet 48 to move up and down. When the pallet lifting control assembly drives the pallet rotating assembly and the pallet 48 to descend, the pallet 48 is located below the packing gap and will not interfere with the foam box being transported from left to right on the roller conveyor assembly. When the middle of the foam box corresponds to the packing gap, the pallet lifting control assembly drives the pallet rotating assembly and the pallet 48 to rise. The pallet 48 lifts the bottom of the foam box away from the roller conveyor assembly. The cargo clamping assemblies on both sides of the pallet 48 clamp the bottom of both sides of the foam box. The pallet rotating assembly drives the pallet 48 and the foam box to rotate counterclockwise, so that the tape is pulled and wrapped around the joint of the foam box.

The cargo pressing mechanism 5 is installed on the upper side of the middle part of the two horizontal rectangular tubes 21.

The cargo clamping mechanism 5 includes a clamping power assembly, a mounting disc 55 and a follow-up clamping turntable 56. The clamping power assembly is installed on the upper middle side of the two horizontal rectangular tubes 21. The clamping power assembly is connected to the top of the mounting disc 55. The bottom of the mounting disc 55 is rotatably connected to the follow-up clamping turntable 56. The follow-up clamping turntable 56 is located directly above the middle of the pallet 48.

The mounting disc 55, the follower pressing rotary disc 56 and the rotating shaft 47 are arranged coaxially.

The clamping power assembly includes an arch frame 51, a clamping hydraulic cylinder 52, a vertical guide column 53, and a clamping plate 54. The upper middle sides of the two horizontal rectangular tubes 21 are respectively fixedly connected to the two ends of the bottom of the arch frame 51. The top center of the arch frame 51 is fixedly connected to the vertical clamping hydraulic cylinder 52 through a hydraulic cylinder seat and a cylinder seat screw. The telescopic end of the bottom of the clamping hydraulic cylinder 52 passes through the middle of the arch frame 51 and is fixedly connected to the middle of the upper side of the clamping plate 54. The two ends of the clamping plate 54 are respectively fixedly connected to the bottom ends of the two vertical guide columns 53. The two vertical guide columns 53 are respectively connected to the arch frame 51. The two vertical guide holes on the second 51 are slidably connected, and the bottom of the clamping plate 54 is fixedly connected to the top of the mounting disc 55 by connecting screws. The vertical guide column 53 limits the movement of the clamping plate 54 to prevent the clamping plate 54 from moving in the horizontal direction and damaging the clamping hydraulic cylinder 52. The clamping hydraulic cylinder 52 extends to drive the clamping plate 54 to move downward, which can drive the mounting disc 55 and the follow-up clamping turntable 56 to move downward, and can clamp the box cover of the foam box. The clamping hydraulic cylinder 52 shortens to drive the clamping plate 54 to move upward, thereby driving the mounting disc 55 and the follow-up clamping turntable 56 to move upward.

Since the cargo clamping assembly can only clamp the bottom of both sides of the foam box, and due to the material problem of the foam box, the connection between the box cover and the box body is not tight enough, it is necessary to press the box cover down to make the box cover and the box body tightly connected. At this time, the winding tape can stably close the joint between the box cover and the box body, and the clamping power assembly is used to drive the mounting disc 55 to descend, and the mounting disc 55 drives the follow-up clamping turntable 56 to press the box cover downward. When the foam box rotates, due to the friction between the follow-up clamping turntable 56 and the box cover, the follow-up clamping turntable 56 rotates with the box cover of the foam box, and will not interfere with the rotation of the foam box while pressing the box cover.

The packing tape lifting and swinging control mechanism 6 is installed on the horizontal rectangular tube 21 on the rear side, and the packing tape lifting and swinging control mechanism 6 is located on the right side of the cargo pressing mechanism 5, and the packing tape lifting and swinging control mechanism 6 is connected to the cargo pressing buffer swing arm mechanism 7, and the cargo pressing buffer swing arm mechanism 7 is connected to the tape installation and attachment mechanism 8.

The packing tape lifting component is installed on the rear horizontal rectangular tube 21, and the support arm swinging component is installed on the packing tape lifting component. The support arm swinging component is connected to one end of the support arm 610.

The packing tape lifting assembly includes a fixed seat 61, a vertical slide column 62, a control screw 63, a lifting hand wheel 64, and a lifting bracket 65. The rear side surface of the rear horizontal rectangular tube 21 is fixedly connected with a horizontal fixed seat 61. The middle part of the fixed seat 61 is rotatably connected with a vertical control screw 63 through a bearing. The bottom end of the control screw 63 is fixedly connected with a lifting hand wheel 64. The control screw 63 is threadedly connected to the threaded hole on the lifting bracket 65. Two vertical slide columns 62 are fixedly connected to the fixed seat 61. The two vertical slide columns 62 are respectively slidably connected to the slide column holes on the lifting bracket 65. The control screw 63 is rotated clockwise by the lifting hand wheel 64, and the threaded action of the control screw 63 and the lifting bracket 65 drives the lifting bracket 65 to move upward along the vertical slide column 62. The control screw 63 is rotated counterclockwise by the lifting hand wheel 64 to drive the lifting bracket 65 to move downward along the vertical slide column 62.

The support arm swing assembly includes a swing motor 66, a support 67, an arc track 68, and a fan-shaped slide 69.

The arc track 68 and the fan-shaped slide 69 cooperate to slide and support the support arm 610, so that the end of the support arm 610 away from the swing motor 66 can support heavier components.

The packing tape lifting assembly is used to drive the support arm swing assembly and the support arm 610 to move up and down, so that the tape installed on the tape installation and attachment mechanism 8 is aligned with the joint of the foam box. The support arm swing assembly is used to drive the support arm 610 to swing. When the support arm swing assembly drives the support arm 610 to swing clockwise, the goods are pressed against the buffer swing arm mechanism 7 to allow the tape installation and attachment mechanism 8 to have a buffering force and be pressed against the joint of the foam box. When the support arm swing assembly drives the support arm 610 to swing counterclockwise, the goods are pressed against the buffer swing arm mechanism 7 to drive the tape installation and attachment mechanism 8 away from the packaged and sealed foam box, so that the foam box can be smoothly transported to the left and right through the roller conveying assembly.

Since the foam box is generally a rectangular structure, as the foam box rotates, a cargo-closed buffer swing arm mechanism 7 is provided to allow the tape installation and attachment mechanism 8 to have a buffering effect and to be close to the foam box. The support arm swing assembly drives the support arm 610 to rotate clockwise. After the tape installation and attachment mechanism 8 approaches the foam box, the support arm swing assembly continues to drive the support arm 610 to rotate clockwise. At this time, the buffer cantilever 78 is away from the end of the support arm 610 and the tape installation and attachment mechanism 8 due to the interference of the foam box, causing the buffer disc 77 to rotate counterclockwise relative to the support disc 71. The buffer disc 77 drives the two fan-shaped sliders 75 to rotate counterclockwise in the two arc slide grooves 72 respectively, and the buffer spring 74 on the arc slide rod 73 located on the counterclockwise side of the fan-shaped slider 75 is The buffer cantilever 78 swings clockwise around the support disc 71 with the help of the rebound force of the buffer spring 74. When the foam box rotates, when the tape installation and attachment mechanism 8 corresponds to the edges and corners of the foam box, the buffer cantilever 78 swings counterclockwise around the support disc 71. At this time, the buffer spring 74 on the counterclockwise side of the fan-shaped slider 75 on the arc slide bar 73 is further compressed. When the tape installation and attachment mechanism 8 gradually corresponds to the middle of the side of the foam box, the compressed buffer spring 74 rebounds a certain length, and the buffer cantilever 78 swings clockwise around the support disc 71, so that the tape installation and attachment mechanism 8 is always close to the joint of the foam box, which is conducive to the tape installed on the tape installation and attachment mechanism 8 to be stably attached to the joint of the foam box.

When all the tape rolls need to be installed and packaged, the shell cover 84 is opened upwards, and the tape roll is put on the outside of the tape sleeve 86 in the tape round shell 81. The bottom of the tape roll is supported by the tape roll round support plate 813 to prevent the bottom of the tape roll from rubbing against the bottom of the tape round shell 81 when the tape roll rotates, which can protect the bottom of the tape roll. The tape end of the tape roll extends from the tape outlet 82 to the outside of the tape round shell 81, wherein the adhesive side of the tape faces the front side, and the shell cover 84 is closed. The tape roll is tightened on the tape sleeve 86 by the tape roll tightening assembly. At this time, the tape roll, the tape sleeve 86, the tape roll round support plate 813 and the bottom The shaft 812 can rotate freely relative to the tape shell 81. When the foam box is driven by the cargo clamping rotating mechanism 4 to rotate counterclockwise, the foam box will contact the adhesive side of the tape. The cargo tape clamping assembly is conducive to firmly attaching the tape to the foam box. The foam box rotates counterclockwise to pull the tape. When the tape is pulled out, it will drive the tape roll, the tape sleeve 86, the tape roll round support plate 813 and the bottom shaft 812 to rotate clockwise. The tape is released and attached to the joint of the foam box to complete the packaging and packaging of the foam box. The positioning column 83 is used to position and install the shell cover 84 to prevent the shell cover 84 from rotating relative to the tape shell 81.

Each tightening plate 811 passes through the corresponding side through groove 810, and a guiding slope is provided on the top of one side of each tightening plate 811 located inside the tape sleeve 86, and a tightening stripe is provided on one side of each tightening plate 811 located outside the tape sleeve 86. The bottom center of the shell cover 84 is rotatably connected to the top of the tape mounting column 85, and the tape mounting column 85 is inserted into the middle part of the tape sleeve 86.

When the shell cover 84 is removed, the tape installation column 85 is taken out from the middle part of the tape sleeve 86. At this time, the three tension springs 89 respectively pull the three sliding bottom blocks 88 and the tightening plate 811 toward the center of the tape sleeve 86. At this time, the three tightening plates 811 are retracted into the three side through grooves 810, and the tape roll is sleeved on the outside of the tape sleeve 86. Then the shell cover 84 is installed, and the tape installation column 85 is inserted into the middle part of the tape sleeve 86. Due to the guidance of the guiding inclined surface at the top of the tightening plate 811, the tape installation column 85 is gradually inserted into the area between the three tightening plates 811, and the tightening plate 811 is squeezed out of the side through groove 810.

When the shell cover 84 is installed, the three tensioning plates 811 are in a state of being pulled closer to each other, and the tape mounting column 85 is clamped from three directions. Therefore, the installation of the shell cover 84 is completed. When the tape on the tape roll is released, since the tape mounting column 85 and the shell cover 84 are rotatably connected, the tape mounting column 85 will also rotate with the tape roll. If the shell cover 84 is pulled upward with force, the friction between the tensioning plates 811 and the tape mounting column 85 can be resisted, so that the shell cover 84 and the tape mounting column 85 can be removed upward. At this time, the three tensioning springs 89 retract the three tensioning plates 811 into the three side through grooves 810, and a new tape roll can be replaced.

The card strip 814 and the card slot cooperate to realize the detachable connection between the attachment frame 815 and the attachment rubber roller 816. The cross-section of the card strip 814 and the card slot is dovetail-shaped. After removing the shell cover 84, the card strip 814 can be pulled upward to be taken out of the card slot. When the foam box is driven to rotate counterclockwise, the tape extends from the tape outlet 82 and is wrapped around the joint of the foam box. The attachment rubber roller 816 rolls in contact with the rear side of the tape, presses the tape stably, and attaches it to the joint of the foam box, so that the tape is firmly attached, which is conducive to forming a beautiful packaging appearance.

When in use, the two horizontal rectangular tubes 21 serve as the skeleton of the cargo roller conveyor mechanism 2 for installing the roller conveyor assembly. The roller conveyor assembly conveys the foam box containing the cargo from left to right. When the middle of the foam box containing the cargo corresponds to the packing gap, the cargo clamping and rotating mechanism 4 lifts the foam box containing the cargo through the packing gap to allow the bottom of the foam box to leave the roller conveyor assembly. Then the cargo pressing mechanism 5 presses down the cover of the foam box to make the body and cover of the foam box fit tightly. Then the packing tape lifting and swinging control The control mechanism 6 drives the cargo close buffer swing arm mechanism 7 to swing clockwise, and the cargo close buffer swing arm mechanism 7 drives the tape installation and attachment mechanism 8 to close the joint between the box body and the box cover in the foam box with buffering force, and the tape end of the tape roll installed on the tape installation and attachment mechanism 8 is attached to the joint of the foam box, and then the cargo clamping and rotating mechanism 4 drives the foam box to rotate counterclockwise, and the tape of the tape roll is pulled and released, and is wound around the joint of the foam box, and stops after winding a predetermined number of times, and the packaging of the foam box can be completed.

Embodiment 2, please refer to Figures 1 to 13, this embodiment provides a technical solution: an automatic production line for packaging goods, the structure of this embodiment is roughly the same as that of embodiment 1, the difference is that:

The utility model also includes a tape cutting mechanism 10, which includes a cutting motor 101, a cutting rod 102, a knife seat 103 and an arc blade 104. The cutting motor 101 is installed at the top center of the shell cover 84 through a round seat. The output shaft at the top of the cutting motor 101 is fixedly connected to one end of the cutting rod 102, and the other end of the cutting rod 102 is fixedly connected to the top of the knife seat 103.

The knife seat 103 is pressed against the arc blade 104 through a blade bolt. A blade is arranged on the front side of the arc blade 104, and the blade is serrated.

The tape cutting mechanism 10 also includes a short rod 105, a second fan-shaped slide 106, and a circular track 107. The upper side of the shell cover 84 is fixedly connected to the circular track 107. The circular track 107, the output shaft at the top of the cutting motor 101, and the shell cover 84 are arranged concentrically. The bottom of the cutting rod 102 is fixedly connected to the second fan-shaped slide 106 through the short rod 105. The second fan-shaped slide 106 is slidably connected to the circular track 107. The sliding connection between the second fan-shaped slide 106 and the circular track 107 provides support for the movement of the cutting rod 102, making the movement of the cutting rod 102 more stable.

After the tape is wound a predetermined number of times, the cutting motor 101 drives the cutting rod 102 to rotate counterclockwise around the output shaft of the cutting motor 101, and the cutting rod 102 drives the arc blade 104 to rotate counterclockwise through the knife seat 103. The blade of the arc blade 104 gradually approaches the tape on the rear side of the attached rubber roller 816, and cuts the tape on the rear side of the attached rubber roller 816. The serrated blade can pierce the tape faster and has a good effect on cutting the tape. At this time, the end of the tape outside the tape outlet 82 will be attached to the front side of the attached rubber roller 816 due to static electricity. If there is no static electricity, the end of the tape outside the tape outlet 82 is also longer, which is convenient for winding onto the foam box later.

In order to allow the end of the tape to be better attached to the foam box during the next packaging, the tape installation and attachment mechanism 8 also includes a support rod 817 and a tape limiting stop column 818. The side of the shell cover 84 is provided with a support rod 817, and the bottom of the support rod 817 is connected to the top of the tape limiting stop column 818. The tape limiting stop column 818 is arranged corresponding to the tape outlet 82. The tape passing through the tape outlet 82 passes through the rear side of the tape limiting stop column 818. After the tape is cut, if the end of the tape is The distance between the tape limiting stop post 818 and the outer side of the tape shell 81 is smaller than the distance between the adhesive roller 816 and the outer side of the tape shell 81, so as to avoid the tape limiting stop post 818 interfering with the work of the adhesive roller 816 when the tape is wrapped around the packaging.

Embodiment 3, please refer to Figures 1 to 13, this embodiment provides a technical solution: an automatic production line for packaging goods, the structure of this embodiment is roughly the same as that of embodiment 2, the difference is that:

It also includes a tape tensioning and releasing mechanism 9, which includes a friction disc 91, an arc seat plate 96, an arc friction plate 97 and a synchronous radially movable buffer control component. The bottom end of the bottom shaft 812 is fixedly connected to the middle of the friction disc 91, and a synchronous radially movable buffer control component is installed at the bottom of the tape shell 81. Three arc seat plates 96 are arranged at equal angles around the outer circumference of the friction disc 91, and an arc friction plate 97 is detachably installed on each arc seat plate 96 close to the side of the friction disc 91. The arc friction plate 97 is connected to the arc seat plate 96 by screws.

The arc friction plate 97 and the friction disc 91 can be made of suitable materials as required. It is best to maintain low noise during friction. The arc friction plate 97 can be replaced after being worn.

The synchronous radial movable buffer control component includes a mounting sleeve 92, a rectangular sleeve 93, a rectangular slide rod 94, an adjustment spring 95, a guide wheel 98, an adjustment ring 99, a synchronous guide plate 910, an ear seat 911, an adjustment bolt 912, and a friction convex pattern 913. The bottom of the tape round shell 81 is fixedly connected with the mounting sleeve 92, and the tape round shell 81 is arranged concentrically with the mounting sleeve 92. Three rectangular sliding holes are opened in a circular array in the middle of the side of the mounting sleeve 92, and a rectangular sleeve 93 is slidably connected in each rectangular sliding hole. The rectangular sleeves 93 are distributed along the radial direction of the mounting sleeve 92, and a rectangular slide rod 94 is slidably connected in each rectangular sleeve 93. One end of each rectangular slide rod 94 located in the mounting sleeve 92 is fixedly connected to the middle of the arc seat plate 96, and the rectangular The rod section of the slide rod 94 located between the arc seat plate 96 and the rectangular sliding sleeve 93 is sleeved with an adjustment spring 95, and the top of one end of each rectangular sliding sleeve 93 located on the outside of the mounting sleeve 92 is rotatably connected to a guide wheel 98, and the bottom of the tape round shell 81 is rotatably connected to an adjustment ring 99, the adjustment ring 99 is located on the outside of the mounting sleeve 92, and the mounting sleeve 92 and the adjustment ring 99 are arranged concentrically, and the outer side of the adjustment ring 99 is provided with a friction convex pattern 913, and the inner side of the adjustment ring 99 is provided with three synchronous guide plates 910 in an annular array, and the side of the synchronous guide plate 910 away from the adjustment ring 99 is set as an arc surface, and the outer peripheral side of the adjustment ring 99 is provided with an ear seat 911, and the ear seat 911 is threadedly connected with an adjustment bolt 912, and the top of the adjustment bolt 912 is pressed against the bottom surface of the tape round shell 81;

When it is necessary to adjust the friction between the circular arc friction plate 97 and the friction disc 91 to adjust the resistance to the rotation of the tape roll and the tape sleeve 86, loosen the adjustment bolt 912, and the top of the adjustment bolt 912 leaves the bottom surface of the tape shell 81. With the help of the friction convex pattern 913, hold the adjustment ring 99 clockwise, and the arc surface of the synchronous guide plate 910 gradually rolls with the corresponding guide wheel 98. The arc surface of the synchronous guide plate 910 cooperates with the guide wheel 98 to gradually push the rectangular sliding sleeve 93 into the inner side of the mounting sleeve 92. At this time, the rectangular sliding sleeve 93 compresses the adjustment spring 95, and the elastic force of the adjustment spring 95 increases, which will push the circular arc seat plate 96 and the circular arc friction plate 97 closer to the friction disc 91, and the friction force on the friction disc 91 when rotating becomes larger, and the tape roll and the tape sleeve are more stable. 86. The rotational resistance of the tape roll round support plate 813 and the bottom shaft 812 becomes greater, which is conducive to winding the tape more tightly around the foam box. With the help of the friction convex pattern 913, the adjusting ring 99 is rotated counterclockwise, so that the arc surface of the synchronous guide plate 910 reduces the pressure on the guide wheel 98, the rectangular sliding sleeve 93 extends out of the mounting sleeve 92, the pressure received by the adjustment spring 95 becomes less, and the friction force received by the friction disc 91 during rotation becomes smaller, and the rotational resistance of the tape roll, the tape sleeve 86, the tape roll round support plate 813 and the bottom shaft 812 will become smaller. After adjusting the rotational resistance of the tape roll, the tape sleeve 86, the tape roll round support plate 813 and the bottom shaft 812, tighten the adjusting bolt 912, and the top of the adjusting bolt 912 is pressed against the bottom surface of the tape round shell 81 again, and the adjusting ring 99 can no longer rotate.

It should be noted that if the resistance is too great, the end of the tape cannot be attached to the foam box when the packaging is just started, which will cause packaging failure. Therefore, the rotation resistance of the tape roll, tape sleeve 86, tape roll round support plate 813 and bottom shaft 812 should not be as large as possible.

Since the tape roll, tape sleeve 86, tape roll round support plate 813 and bottom shaft 812 can rotate freely relative to the tape round shell 81, after the foam box stops rotating, due to the pulling of the tape on the tape roll, the tape roll, tape sleeve 86, tape roll round support plate 813 and bottom shaft 812 will continue to rotate one end distance due to inertia, which will easily cause the tape on the tape roll to be released too much, and the tape will easily stick to the outside of the tape outlet 82. At this time, the staff has to intervene and handle it. At the same time, since the tape roll can rotate freely, the tape cannot be tightened when it is wrapped around the foam box, resulting in more wrinkles in the tape when it is wrapped. If the foam box is not packed tightly enough and the joints of the foam box are not tightly closed, the fresh goods inside will also spoil too quickly. Therefore, a There is a synchronous radial movable buffer control component. The synchronous radial movable buffer control component allows the three arc seat plates 96 and the arc friction plates 97 to provide friction for the rotation of the friction disc 91 in three directions, so that the friction disc 91 is more evenly subjected to the friction in all directions, to avoid the bottom shaft 812 and the tape round shell 81 from having a clearance after long-term use, causing the tape roll to shake left and right when rotating, and to avoid the release of the tape being unstable and causing wrinkles. At this time, there is resistance to the rotation of the tape roll, the tape sleeve 86, the tape roll round support plate 813 and the bottom shaft 812. Due to the resistance to the rotation of the tape roll, the released tape can be tightened to the foam box, allowing the tape to be more evenly attached to the joints of the foam box, thereby providing better protection for the fresh goods inside and making the foam box more beautiful after packaging.

Embodiment 4, please refer to Figures 1 to 13, this embodiment provides a technical solution: an automatic production line for packaging goods, the structure of this embodiment is roughly the same as that of embodiment 3, the difference is that:

Two guiding and straightening plates 32 are installed at the bottom of the left ends of the two horizontal rectangular tubes 21 through the guiding and straightening plate synchronous movement control component. The two guiding and straightening plates 32 are located on the upper side of the left end of the roller conveying component, and the left ends of the two guiding and straightening plates 32 are respectively opened outward, and the left ends of the two guiding and straightening plates 32 are arc-shaped structures. Grooves 36 are equidistantly arranged on the opposite sides of the two guiding and straightening plates 32, and a vertical guiding roller 37 is rotatably connected in each groove 36.

The synchronous movement control assembly of the guiding and squaring plate includes a longitudinal guide rod 31, a vertical plate 33, an adjustment hand wheel 34, and a vertical plate longitudinal screw 35. The longitudinal guide rod 31 is fixedly connected between the left ends of the two horizontal rectangular tubes 21.

The threads on the two vertical plate longitudinal screws 35 are in opposite directions. The two vertical plate longitudinal screws 35 are correspondingly arranged front and back, and the ends of the two vertical plate longitudinal screws 35 are fixedly connected together. The end of the vertical plate longitudinal screw 35 is fixedly connected with an adjusting hand wheel 34. By means of the adjusting hand wheel 34, the two vertical plate longitudinal screws 35 are twisted clockwise. Since the threads on the two vertical plate longitudinal screws 35 are in opposite directions, the threads of the vertical plate longitudinal screws 35 and the vertical plate 33 can drive the two vertical plates 33 to approach each other along the longitudinal guide rod 31, thereby driving the two guide squaring plates 32 to approach each other, which is suitable for narrower foam boxes. By means of the adjusting hand wheel 34, the two vertical plate longitudinal screws 35 are twisted counterclockwise, and the two vertical plates 33 move away from each other along the longitudinal guide rod 31, thereby driving the two guide squaring plates 32 move away from each other, which is suitable for wider foam boxes.

When the foam box moves from left to right with the roller conveyor assembly, it cannot be guaranteed that the foam box will swing exactly in a square shape. After the foam box is lifted up by the pallet 48, if the pallet 48 does not swing, it is not easy to be clamped by the cargo clamping assembly. Therefore, a cargo guiding and straightening mechanism 3 is provided. The foam box moves from left to right and first enters between the left ends of the two guiding and straightening plates 32. Due to the guidance of the two guiding and straightening plates 32, the foam box is gradually swung and passes between the right ends of the two guiding and straightening plates 32. The foam box is completely swung. Since the material of the foam box is easily worn by the guiding and straightening plates 32, a guide roller 37 is provided. The guide roller 37 is in rolling contact with the foam box to avoid wear on the foam box.
