For the purpose of making the technical solution and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and examples of implementation. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

Referring to fig. 1a, the present invention provides a film wrapping machine 100 for pushing a package into a package having an opening at one side and transferring the package to a designated position for corner cutting during the production of film wrapping.

The film packaging machine 100 comprises a box pushing mechanism 3, a bag expanding mechanism 4, a feeding mechanism 5, a conveying mechanism 6 and a corner cutting mechanism 7, wherein the bag expanding mechanism 4 is used for providing packaging bags with one side opening; the feeding mechanism 5 is used for providing a packaging box; the box pushing mechanism 3 is used for pushing the packaging box into the packaging bag, and alternatively, the box pushing mechanism 3 is also used for pushing the packaging bag together with the packaging box into the conveying mechanism 6, so that the conveying mechanism 6 can be used for fixing the packaging box wrapped with the packaging bag and conveying the packaging box to the corner cutting mechanism 7 for corner cutting.

It will be appreciated that the conveying mechanism 6 includes at least two fixed box assemblies, the at least two fixed box assemblies are used for alternately fixing the packing boxes pushed by the pushing mechanism 3, the conveying mechanism 6 further includes a rotating assembly, the at least two fixed box assemblies are uniformly arranged on the rotating assembly and used for fixing the packing boxes, and the rotating assembly rotates to enable the at least two fixed box assemblies to sequentially and circularly convey the packing boxes. The conveying mechanism 6 may also be a manipulator capable of alternately clamping and conveying the packages, so long as the manipulator can alternately fix the packages and convey the packages to the corner cutting mechanism 7 for corner cutting.

Referring to fig. 1b, specifically, the pushing mechanism 3 includes at least two pushing assemblies 31, in this embodiment, two pushing assemblies 31 are disposed opposite to each other in a direction perpendicular to the ground.

Referring to fig. 2a, the pushing assembly 31 includes a pushing member 311 and a first rail 312, wherein the pushing member 311 is slidably connected to the first rail 312, so that the pushing member 311 can be moved to any position along the direction of the first rail 312 and fixed.

Specifically, the first track 312 includes a push drive 3121, a push lead screw 3123, and a push travel 3125. The pushing driving member 3121 is used for driving the pushing screw 3123 to rotate, and the pushing moving member 3125 is sleeved on the pushing screw 3123. The pushing member 3125 is fixed to the pushing member 311, and when the pushing screw 3123 rotates, the pushing member 3125 drives the pushing member 311 to move along the pushing screw 3123.

As an embodiment, the packages pushed by the at least two pushing assemblies 31 are located at the same position, i.e. the packages are pushed by the at least two pushing assemblies 31 at the same position. The contact positions of the at least two pushing box components 31 when pushing the packing box are the same as the contact positions of the packing box, namely, when pushing the packing box, the at least two pushing box components 31 need to adjust the positions among the pushing box components 31 each time, as long as the positions among the pushing box components 31 are adjusted to ensure that the contact positions of the pushing box components 31 and the packing box are the same each time when pushing the packing box, at least one pushing box component 31 needs to move the adjustment positions when pushing the packing box.

Referring to fig. 2b, it can be understood that the movement path of the pushing element 311 in the single pushing cycle includes a travel path S1, a return path S2 and a position adjustment path S3, wherein the travel path S1 is a forward path for pushing the package, the return path S2 is a return path opposite to the travel path S1, and the yielding path S3 is a path for the pushing element 311 to exit the travel path S1 after the pushing element 311 is pushed to yield the pushing position for the other pushing element 311. When one pushing element 311 pushes the package (i.e. is located in the going path S1), the other pushing element 311 is located in the returning action (i.e. is located in the returning path S2) or the yielding action (i.e. is located in the yielding path S3), so as to ensure that the two pushing elements 311 push the package alternately, reduce the interval time of pushing the package, and improve the pushing efficiency.

Referring to fig. 2b, the travel path S1 is greater than the pushed distance S3 of the package. So long as it is ensured that when one push member 311 is located on the outgoing path S1 (i.e. pushing the package), the other push member 311 is in the return path.

Referring to fig. 3a and 3b, an X-Y-Z axis is defined, wherein the X axis is a direction along which the pushing member 311 moves along the first track 312, the Y axis is a direction parallel to the ground and perpendicular to the X axis, and the Z axis is perpendicular to the ground.

The push box 311 comprises a first structure 3111, a second structure 3113 and a pin 3118, the pin 3118 being adapted to contact and push the package. The first structure 3111 is slidably coupled to the second structure 3113, and the thimble 3118 is slidably coupled to the second structure 3113. The first structure 3111 and the second structure 3113 are relatively slidable in the Z-axis direction to adjust a distance between the first structure 3111 and the second structure 3113. The first structure 3111 is fixed to the pushing member 3125 such that the pushing member 3125 moves the first structure 3111 and the second structure 3113.

Referring to fig. 3a-3d, specifically, the first structural member 3111 includes a second track 3112 and a third track 3114, the third track 3114 is slidably connected to the second track 3112, and the third track 3114 is movable to an arbitrary position along the direction of the second track 3112 and fixed.

The second structure 3113 is slidably connected to the third rail 3114, and the second structure 3113 is movable to an arbitrary position along the third rail in the Z-axis direction and fixed.

Referring to fig. 3a and 3e, the second structural member 3113 includes a fourth rail 3116, the fourth rail 3116 is slidably connected to the third rail 3114, and the fourth rail 3116 is movable to an arbitrary position along the direction of the third rail 3114 and fixed. The needle 3118 is slidably coupled to the fourth track 3116.

It is appreciated that the needle 3118 may be fixed to the fourth track 3116, and that the position of the needle 3118 in the Y-axis direction may be adjusted via the second track 3112.

Optionally, the surface of the thimble 3118 contacting the package is provided with a soft pad, so that the thimble 3118 forms a buffer when pushing the package, and reduces impact on the package caused by the pushing force of the thimble 3118, and prevents deformation of the package.

The direction of the fourth track 3116 is the same as the direction of the second track 3112, and the thimble 3118 may be moved to an arbitrary position along the direction of the second track 3112 and fixed.

It will be appreciated that the second and third tracks 3112, 3114 are configured such that the push assembly 31 can adjust the position of the needle 3118 in multiple directions to accommodate pushing of packages of various sizes, depending on the size of the package or the position of the device.

It will be appreciated that, as another embodiment, the second track 3112, the third track 3114 and the fourth track 3116 may be provided with a combination of one or more tracks, as long as the needle 3118 is movable in the Y-axis and/or the Z-axis and can push the package.

It should be understood that, as another embodiment, the second track 3112, the third track 3114 and the fourth track 3116 may be omitted, that is, the thimble 3118 may be directly fixed to the pushing member 3123, so long as the pushing assembly 31 can push the package.

Optionally, referring to fig. 4, the pushing mechanism 3 further includes a flattening component 32, where the flattening component 32 is connected to the pushing component 31, specifically, the flattening component 32 includes a first bag-expanding sheet 321 and a second bag-expanding sheet 322 slidably connected to a fourth track 3116, a rotating belt 323 driven by a rotating wheel is disposed on the fourth track 3116, the rotating belt 323 is an endless conveyor belt, when the rotating belt 323 is rotationally driven by the rotating wheel, the rotating belt 323 is divided into two moving belts with opposite moving directions on both sides of the rotating wheel, the first bag-expanding sheet 321 is fixed to one moving belt, the second bag-expanding sheet 322 is fixed to the other moving belt, so that when the rotating belt 323 rotates, the first bag-expanding sheet 321 and the second bag-expanding sheet 322 can be relatively close to or far away from each other, so that when the ejector pin 3118 pushes the package into the package, the first bag-expanding sheet 321 and the second bag-expanding sheet 322 are inserted into the package and far away from each other to expand the package, so as to press the gap on the surface of the package to the package on the surface of the package to the two sides of the first bag-expanding sheet 321 and the second bag-expanding sheet 322, so as to facilitate the processing of the next package.

As an embodiment, the first and second expansion pieces 321 and 322 are flush with the top needle 3118 at the side contacting the package, and the positions of the first and second expansion pieces 321 and 322 are matched with the positions of the top needle 3118 in the Y direction, so long as the first and second expansion pieces 321 and 322 are simultaneously inserted into and spread out the package when the push box assembly 31 pushes the package into the package with one side opened through the top needle 3118.

Referring to fig. 5a-5d, in particular, the feeding mechanism 5 includes a feeding belt 51 and a lifting assembly 52. The feeding belt 51 is used for conveying the packing boxes, and the jacking component 52 is used for conveying the packing boxes on the feeding belt 51 to the same height as the bag expanding mechanism 4. The jacking component 52 is arranged between the feeding belt 51 and the bag expanding mechanism 4.

When feeding, the initial position of the jacking component 52 (such as the relative position of the jacking component 52 and the feeding belt 51 in fig. 5 a) is located at the same height as the feeding belt 51, and the feeding belt 51 conveys the package boxes to the jacking component 52;

when lifting, as shown in fig. 5b, the lifting component 52 sends the package to the opening of the package, so that the two pushing components 31 can push the package into the package;

in the first pushing process, as shown in fig. 5c, one of the two pushing assemblies 31, the pushing assembly 31 pushes the package into the package bag in the bag expanding mechanism 4;

when the return stroke of the box pushing assembly 31 is not finished, as shown in fig. 5d, the jacking assembly 52 returns to the initial position, the next package box is sent to the jacking assembly 52 by the feeding belt 51, and meanwhile, the bag expanding mechanism 4 provides the next package bag with one side opening;

in the second pushing, as shown in fig. 5e, the jacking component 52 pushes the next package box into the opening of the next package bag from the other pushing component 31, and the other pushing component 31 pushes the package box into the package bag according to the above manner, at this time, the returning of the pushing component 31 in the first pushing is completed.

The above steps are cycled to alternately push the packages into the corresponding packages.

It will be appreciated that the above-mentioned jacking assembly 52 enables the bag expanding mechanism 4 to deliver the bags having one side open to a predetermined position before jacking up the packages to the opening of the bags, ensuring that one package corresponds to one bag.

In the process of returning the package bags to the first pushing assembly 31, the other pushing assembly 31 starts to push the next package bag, and the two pushing assemblies 31 alternately push the package bags in a circulating manner, so as to alternately push the package bags into the corresponding package bags.

It will be appreciated that the frequency of pushing of any one of the push assemblies 31 is lower than the frequency with which the bag expansion mechanism 4 provides the packages and the feed mechanism 5 provides packages, so long as it is ensured that when one push assembly 31 is pushing a package, the other push assembly 31 is in return.

It will be appreciated that, as another embodiment, the pushing mechanism 3 may include more than two pushing assemblies 31, for example, three, four or more pushing assemblies 31 may be provided, and the plurality of pushing assemblies 31 may push the packages in a circulating and alternating manner, so as to further improve the working efficiency of pushing the packages.

The packing box is alternately pushed, at least two box pushing components 31 are arranged in the box pushing mechanism 3, so that the process of pushing the packing box into a packing bag can be ensured to be alternately continuous, and the phenomenon that the single box pushing component 31 pushes the packing box into the packing bag and then waits for returning to push for the next time in an idle stroke manner is avoided, and the production efficiency is influenced.

The above embodiments are merely preferred embodiments of the present invention, and are not intended to limit the present invention, but any modifications, equivalents, improvements, etc. within the principles of the present invention should be included in the scope of the present invention.
