Description

Folding paper cup and bowl making equipment Technical Field

The invention relates to equipment for making paper cups and bowls.

Background Art

The molding and production of paper containers such as paper cups or paper bowls (collectively referred to as cups and bowls) requires the intervention of a turntable. There are relatively many workstations. Not only the bottom of the cup needs to be made, but also the mouth of the cup. Both the bottom and the mouth of the cup require multiple processes at different workstations, and the turntable carries the body of the cup and bowl to rotate to each workstation for corresponding molding and production. The turntable corresponds to many workstations and the rotation method of the turntable leads to complex structures, workstations and coordinated operation. It is necessary to make an additional cup bottom and connect it to the body to form a cup body. In some other molding processes, multiple turntables are required (the bottom of the cup and the mouth of the cup are made on different turntables) for coordination and connection (the body is transferred and formed on multiple turntables, which makes the entire processing technology more complicated and less stable. Not only the body molding process is required, but also the cup bottom production work and the cup bottom and body connection process are required.

After the cup body is made, the whole body of the cup body usually presents a taper or slope, and opens at a certain angle. When rolling, it needs to be rolled in accordance with the taper or slope. The rolling is difficult, the rolling effect is poor, and it is easy to deform and wrinkle, and the requirements for paper materials are high. For this reason, the upper part of the cup body is developed as a vertical section to reduce the difficulty of rolling, reduce the material requirements for paper, and better ensure the rolling effect. The rolling is not easy to deform and wrinkle. How to roll the lower section of the cup body with a taper or slope and the upper part of the cup body as the vertical section to be rolled needs to be solved.

During the production of cups and bowls, paper sheets need to be fed forward. Currently, the paper sheets are pushed forward by the paper support platform (there is a channel on the paper support platform for the paper pusher to move back and forth). There is a tube body enclosure molding mold above the paper support platform. The paper sheets on the paper support platform are embraced on the tube body enclosure molding mold, and the left and right overlaps of the paper sheets are bonded (by glue or ultrasound, etc.). Now we are developing a device that does not perform tube body enclosure molding above the paper support platform. For example, the cup body (including the tube body and the bottom of the cup) is directly formed in front of the paper support platform through the upper and lower molds in combination with stamping and folding. How to adapt to this molding method to the paper sheet feeding needs to be solved urgently. It not only needs to meet the paper sheet feeding needs, but also needs to be able to cooperate with the molding needs.

After paper containers such as paper cups or paper bowls are made in the forming equipment, they will be output one by one. Usually, the cups and bowls are demolded from the forming mold and put into the pneumatic pipe, and the wind blows the cups and bowls to fly in the pipe for collection. Now a device has been developed in which the cups and bowls are clamped and translated by a robot after forming and output one by one (cups and bowls). How to configure the cup collection device to meet the cup collection needs in the future needs to be solved, and how to collect the output cups and bowls needs to be solved urgently.

The cup body folding and forming station 28 is equipped with a cup body folding and forming device, and the cup body folding and forming device folds the paper sheet into the cup body of the paper cup bowl at the cup body folding and forming station 28 .

The cup mouth oil dipping station 29 is equipped with an oil dipping device, and the cup body is dipped in oil at the cup mouth oil dipping station 29 by the oil dipping device, and the cup mouth can be rolled smoothly after oil dipping and lubrication.

The cup mouth preheating station 30 is equipped with a preheating device. After the cup body is dipped in oil, the preheating device completes the preheating of the cup mouth of the cup body in the cup mouth preheating station 30. The preheated cup mouth can be rolled more smoothly.

The collecting station 32 is equipped with a cup receiving device, and finally the cup body is output from the collecting station 32 and received and collected by the cup receiving device.

The heating component and/or gluing component in the paper feeding device can heat and/or gluing the paper to be bonded for subsequent folding and forming connection. The cup body folding and forming device configured at the cup body folding and forming station has a matching upper forming mold and a lower forming mold for folding and forming the paper.

The station layout is arranged in a straight line and the station combination method of paper feeding station 33, cup body folding and forming station 28, cup bowl dipping oil station 29, cup bowl preheating station 30, cup bowl curling station 31 and collection station 32 is adopted to optimize the station combination structure, and only need to fold and form paper cups and bowls at the folding and forming station (single station), simplify the structural layout, can run relatively stably in a straight line, and avoid the use of a complex rotary station connection method. Among them, the cups and bowls (semi-finished products and finished products) are transferred and connected by the translation manipulator longitudinally, and can be transferred to different stations in a straight line to stay for corresponding processing and production. It adopts a linear operation, with a relatively simple structure, relatively low cost, and relatively high stability. Avoid the complex structure of a turntable with multiple stations and multiple links.

Based on the above embodiments, the following optimization or further explanation may be performed.

As shown in the figure, the paper feeding device in the embodiment of the present embodiment includes a paper support platform 35, and the paper support platform 35 has a paper support feeding surface 36, and the paper sheet is supported and slid by the paper support feeding surface 36, and the paper support feeding surface 36 is also equipped with a paper pushing component 37, and the paper pushing component 37 will cooperate to push the paper sheet forward to slide on the paper support feeding surface 36. The paper pushing component 37 can be a straight pushing component (for straight-line pushing forward), such as a pushing head (for example, a one-way pushing head) and other mature structured paper pushing components, or multiple paper pushing components can be used to form a multi-stage pushing structure to push the paper sheet forward.

The upper side of the paper support feeding surface 36 is also provided with a heating component 38 (such as a hot air blowing device) and/or a gluing component (such as a glue gun device). The heating component 38 can heat the coating layer at the paper sheet to be bonded so as to facilitate bonding during subsequent molding and/or the gluing component can heat the gluing (such as dispensing glue, etc.) at the paper sheet to be bonded so as to facilitate bonding during subsequent (folding) molding.

The paper support platform 35 is also provided with a folding and forming feed opening 39. The paper pieces on the paper support feeding surface 36 of the paper support platform 35 will go down from the folding and forming feed opening 39 for subsequent folding and forming. The cup body folding and forming device will be arranged at the folding and forming feed opening 39. The folding and forming feed opening 39 is opened on the paper support feeding surface 36 so that the paper pieces can be pushed and slid forward to go down to the folding and forming feed opening 39; the left side, right side and rear side of the folding and forming feed opening 39 are respectively connected with the paper support feeding surface 36, that is, the paper support feeding surface 36 has corresponding parts connected on the left side, right side and rear side of the folding and forming feed opening 39. When the paper pieces are pushed and slid forward, they can smoothly and stably reach the folding and forming feed opening 39 to wait (to enter the cup body folding and forming device of the cup body folding and forming station 28), and the cup body folding and forming station 28 will be connected at the folding and forming feed opening 39.

The folding and forming feed opening 39 is located at the front side (output side) of the heating component 38 and/or the gluing component, that is, when the paper sheet is pushed and slid forward, it first passes through the heating component 38 and/or the gluing component to process the adhesion area, and then is pushed to the folding and forming feed opening 39.

Principle and effect: The paper feeding device can push the paper forward in a straight line, and preheat or gluing (i.e. pretreatment) the part of the paper to be bonded during the pushing process, so that it can be smoothly bonded and fixed during the subsequent folding and forming. It combines paper feeding with pretreatment, and directly transports the pretreated paper to the folding and forming feed port 39 to wait for subsequent folding and forming. It can not only cooperate with efficient paper feeding to the folding and forming feed port 39, but also cooperate with folding and forming for pretreatment, thereby meeting the needs of folding paper into cups and bowls.

For example, the left and right sides of the folding and forming feed opening 39 are respectively provided with a paper pressing paper 40, and a paper passing matching gap is left between the paper pressing paper 40 and the paper supporting and feeding surface 36 below. The left and right edges of the paper sheet can be pressed on the paper supporting and feeding surface 36 by the paper pressing paper 40 on the left and right sides of the folding and forming feed opening 39, and the left and right edges of the paper sheet will be located in the paper passing matching gap to advance, ensuring that the paper sheet advances smoothly and stably through the folding and forming feed opening 39, so that the paper sheet can cover the folding and forming feed opening 39, and when the subsequent paper sheet goes down for folding and forming, the paper passing matching gap can also protect the left and right edges of the paper sheet to allow the paper sheet to go down stably. The inner edge of the paper pressing paper 40 can be set as an arc edge to better fit the arc shape on both sides of the paper sheet, avoiding the edge bending when the paper sheet goes down.

The paper pressing paper 40 is connected to the paper supporting platform 35, and the installation and connection are relatively convenient. A gap height adjustment replacement block 42 is also connected between the paper pressing paper 40 and the paper supporting platform 35. By replacing the gap height adjustment replacement block 42 with different thicknesses, the size of the paper matching gap can be adjusted, and the pressure of the paper matching gap to protect the clamped paper can be adjusted. The input side of the paper pressing paper 40 can be provided with an upward introduction trumpet to facilitate paper introduction.

The left and right sides of the paper support feeding surface 36 are also provided with paper sheet side limit stoppers 43, which can limit the left and right sides of the paper sheet so that the position of the paper sheet does not shift when it is pushed forward on the paper support feeding surface 36. The paper sheet side limit stoppers 43 on the left and right sides of the folding and forming feeding opening 39 are located between the paper support feeding surface 36 and the paper pressing paper 40, so that the left and right sides of the paper sheet advancing at the folding and forming feeding opening 39 can also be limited.

The paper support platform 35 is also provided with a feed opening adjustment and replacement frame 44. The paper feeding surface 36 includes the upper side surface of the feed opening adjustment and replacement frame 44. The upper side surface of the feed opening adjustment and replacement frame 44 will also serve as a part of the paper feeding surface 36. A plurality of plates (such as a heat dissipation plate with a heat dissipation structure (such as a heat dissipation hole) can be provided on the paper support platform 35 corresponding to the heating component 38) or a combination of frames to form the paper feeding surface 36. The inner edge of the feed opening adjustment and replacement frame 44 is the edge of the folding and forming feed opening 39. The feed opening adjustment and replacement frames 44 of different specifications and sizes are replaced to adapt to paper sheets of different sizes for folding and forming.

The front side of the folding and forming discharge port 39 is also provided with a paper feeding limiting component 45 (such as a paper feeding limiting block, etc.), and the paper feeding limiting component 45 is arranged on the left and right sides of the folding and forming discharge port 39. The paper feeding limiting component 45 (such as a paper feeding limiting block, etc.) can be adjusted in position to adapt to paper sheets of different specifications, sizes and shapes.

In addition, the front side of the folding and forming feed opening 39 is also equipped with an auxiliary paper supporting component (such as an auxiliary paper supporting platform 35), which can support the front side of the paper sheet, making the paper sheet more stable when staying and going down at the folding and forming feed opening 39. The auxiliary paper supporting component is installed on the support frame.

As an additional optimization, the upper side of the paper support and feeding surface 36 is also provided with a paper pressing mechanism 46, which can cooperate to press the paper sheet on the paper support and feeding surface 36 to prevent the paper sheet from shifting when being pushed forward. By pressing the paper, the paper sheet will not be lifted up to prevent the paper pushing component 37 from pushing in vain. The paper pressing mechanism 46 can also cooperate with the paper pressing to ensure that the one-way paper pushing component 37 (including a paper pushing block with a spring swing on the paper pushing seat) can be smoothly retracted without shifting the paper. The paper pressing mechanism 46 includes a paper pressing rod 47 and a paper pressing chain 48. The paper pressing rod 47 is arranged on the left and right sides of the paper pressing chain 48. The front and rear ends of the paper pressing chain 48 are respectively connected to the mounting seat 49 for setting and fixing. The paper pressing rod 47 can press the paper to prevent the paper from curling up, and can also press the paper to make it move forward smoothly. However, it is difficult to achieve compaction and stabilization by the paper pressing rod 47 alone. The paper pressing chain 48 is compacted and stabilized in the middle position. The paper pressing chain 48 is relatively soft and can be deformed so that it can fit and compact the paper. The paper is not easy to deviate, and the cost of combining the paper pressing rod 47 and the paper pressing chain 48 is relatively low. A gantry frame can be set on the paper support platform 35 for the mounting seat 49, the paper pressing rod 47, the heating component 38 and/or the gluing component to be suspended and installed.

In addition, there are many ways to feed paper sheets to the paper support 35. For example, currently single paper sheets are stacked in a material library, and a suction nozzle is used to suck each paper sheet from the bottom of the material library downward to the paper support 35, and then the paper pushing component 37 pushes the paper forward. Other feeding methods are also possible.

As shown in the figure, the translation robot 200 in the embodiment of this embodiment includes four groups of cup-bowl clamping assemblies 1, and the cup-bowl clamping assemblies 1 include a left clamping part 2 and a right clamping part 3 that are paired on the left and right. The left clamping part 2 and the right clamping part 3 in each group of cup-bowl clamping assemblies 1 will clamp the cups and bowls when they are brought together, and release the cups and bowls when they are separated.

The left clamping parts 2 in each group of cup and bowl clamping assemblies 1 are respectively arranged on the left bracket 4, and the left bracket 4 is connected to the first movable assembly 5. The left bracket 4 moves together with the first movable assembly 5. The first movable assembly 5 includes a first transverse displacement seat 6 (capable of transverse displacement) and a first longitudinal displacement seat 7 (capable of longitudinal displacement) that are connected to each other, so that the first movable assembly 5 can move transversely and longitudinally. The left bracket 4 will move transversely (left and right) and longitudinally (forward and backward) with the first movable assembly 5.

The right clamping parts 3 in each group of cup and bowl clamping assemblies 1 are respectively arranged on the right bracket 8, and the right bracket 8 is connected to the second movable assembly 9. The right bracket 8 moves together with the second movable assembly 9. The second movable assembly 9 includes a second transverse displacement seat 10 (capable of transverse displacement) and a second longitudinal displacement seat 11 (capable of longitudinal displacement) that are connected to each other, so that the second movable assembly 9 can move transversely and longitudinally, and the right bracket 8 will move transversely (left and right) and longitudinally (forward and backward) with the second movable assembly 9.

Principle and effect: The left clamping part 2 and the right clamping part 3 in each group of cup and bowl clamping assemblies 1 cooperate with each other to clamp the corresponding cup and bowl for longitudinal movement, so that the cup and bowl can be transferred in a straight line direction so as to stop at different stations for corresponding processing and production. The linear operation is adopted, and the multi-station stop structure is coordinated. The structure is relatively simple, the cost is relatively low, and the stability is relatively high. The four groups of cup and bowl clamping assemblies 1 can operate synchronously and cooperate to efficiently transfer cups and bowls. Avoid the complex structure of a turntable with multiple stations and multiple links.

For example, the first transverse seat 6 is connected to the first longitudinal seat 7, that is, the first transverse seat 6 moves transversely on the first longitudinal seat 7, and the first transverse seat 6 can move longitudinally with the first longitudinal seat 7; the second transverse seat 10 is connected to the second longitudinal seat 11, that is, the second transverse seat 10 moves transversely on the second longitudinal seat 11, and the second transverse seat 10 can move longitudinally with the second longitudinal seat 11, and the structure is relatively compact. Or, the first longitudinal seat 7 is connected to the first transverse seat 6, and the second longitudinal seat 11 is connected to the second transverse seat 10.

For another example, the first transverse movement seat 6 is equipped with a first transverse movement guide rail 12, and the first transverse movement seat 6 can be guided to move transversely by the first transverse movement guide rail 12; the first longitudinal movement seat 7 is equipped with a first longitudinal movement guide rail 13, and the first longitudinal movement seat 7 is guided to move longitudinally by the first longitudinal movement guide rail 13, and the movement is more stable through the guided cooperation; the second transverse movement seat 10 is equipped with a second transverse movement guide rail 14, and the second transverse movement seat 10 can be guided to move transversely by the second transverse movement guide rail 14; the second longitudinal movement seat 11 is equipped with a second longitudinal movement guide rail 15, and the second longitudinal movement seat 11 is guided to move longitudinally by the second longitudinal movement guide rail 15, and the movement is more stable.

For example, a first transverse guide rail 12 is arranged on the first longitudinal movement seat 7, the first transverse movement seat 6 is connected with the first transverse guide rail 12, the first longitudinal movement seat 7 is connected with the first longitudinal movement guide rail 13, and the first longitudinal movement guide rail 13 is connected and installed on the left support frame 16 for support; a second transverse guide rail 14 is arranged on the second longitudinal movement seat 11, the second transverse movement seat 10 is connected with the second transverse guide rail 14, the second longitudinal movement seat 11 is connected with the second longitudinal movement guide rail 15, and the second longitudinal movement guide rail 15 is connected and installed on the right support frame 17 for support.

For example, the first transverse shift seat 6 is connected to the first transverse shift driving device, and the second transverse shift seat 10 is connected to the second transverse shift driving device; the first longitudinal shift seat 7 is connected to the first longitudinal shift driving device, and the second longitudinal shift seat 11 is connected to the second longitudinal shift driving device. The corresponding driving device drives the transverse or longitudinal shift, and there are many types of driving devices, such as motors or cylinders as power drives.

For another example, the first transverse shift seat 6 is connected to the first transverse shift driving cylinder 18 or the motor, and the first transverse shift driving cylinder 18 or the motor is arranged on the first longitudinal shift seat 7, and the first transverse shift seat 6 is driven by the first transverse shift driving cylinder 18 or the motor to perform transverse shift on the first longitudinal shift seat 7;

The first longitudinal shift seat 7 is connected to the first synchronous belt 20, which is wound around the first pulley set 21. The first pulley set 21 includes a first input wheel 22 and a corresponding driven wheel. The first input wheel 22 is connected to the first synchronous belt 20, and the first synchronous belt 20 is wound around the first pulley set 21. The first synchronous belt 20 drives the first longitudinal shift seat 7 to move longitudinally.

The second longitudinal shift seat 11 is connected to a second synchronous belt 23, which is wound around a second pulley assembly. The second pulley assembly includes a second input wheel and a corresponding driven wheel. The second input wheel is connected to the second synchronous belt 23, and the second synchronous belt 23 is wound around the second pulley assembly. The second longitudinal shift seat 11 is driven by the second synchronous belt 23 to move longitudinally.

The first input wheel 22 is transmission-connected to the first drive motor, and the second input wheel is transmission-connected to the second drive motor, and they are driven by the drive motors respectively, or the first input wheel 22 and the second input wheel are transmission-connected to the synchronous shaft 24, and the synchronous shaft 24 is transmission-connected to the synchronous drive motor 25, and the synchronous drive motor 25 drives the first input wheel 22 and the second input wheel through the synchronous shaft 24, so that the first synchronous belt 20 and the second synchronous belt 23 can be synchronously driven to bypass, so that the first longitudinal movement seat 7 and the second longitudinal movement seat 11 are synchronously longitudinally moved.

The left clamping component 2 and the right clamping component 3 include a mounting plate 26 and a clamping seat 27 disposed on the mounting plate. Different specifications, sizes and shapes of the clamping seat 27 can be replaced according to requirements (such as the shape and size of a cup or bowl, etc.), and multiple clamping seats 27 can be provided.

Between the left clamping part 2 and the right clamping part 3, the cup body folding and forming station 28, the cup bowl mouth oil dipping station 29, the cup bowl mouth preheating station 30, the cup bowl mouth curling station 31 and the collection station 32 are arranged in sequence along the longitudinal direction, that is, the corresponding stations are arranged in a straight line along the longitudinal direction. Then the four groups of cup and bowl clamping assemblies 1 can cooperate to efficiently transfer the cups and bowls along the stations, and cooperate with the five-station stop structure. The first group of cup and bowl clamping assemblies 1 is connected between the cup body folding and forming station 28 and the cup bowl mouth oil dipping station, the second group of cup and bowl clamping assemblies 1 is connected between the cup bowl mouth oil dipping station and the cup bowl mouth preheating station 30; the third group of cup and bowl clamping assemblies 1 is connected between the cup bowl mouth preheating station 30 and the cup bowl mouth curling station 31; the fourth group of cup and bowl clamping assemblies 1 is connected between the cup bowl mouth curling station 31 and the collection station 32.

The first moving assembly 5 and the second moving assembly 9 operate synchronously, that is, the first moving assembly 5 and the second moving assembly 9 move laterally (transversely) and longitudinally (longitudinal) synchronously.

As shown in the figure, the folding and forming device for a paper cup body in an embodiment of the present embodiment comprises a matching forming upper die 65 and a forming lower die 66. The forming upper die 65 is transmission-connected to the upper die lifting drive device, and the forming upper die 65 is lifted and lowered as a whole by the upper die lifting drive device. The upper die lifting drive device can use a motor or a cylinder as a power source. The forming lower die 66 is arranged below the forming upper die 65. When the forming upper die 65 descends, it will cooperate with the forming lower die 66 to fold and form the paper sheet to form the paper cup body.

The following optimization is also adopted in this embodiment, which can vertically arrange the portion of the cup body to be rolled after the paper sheet is folded (almost in an upright state, which can be regarded as a vertical state, with relatively no slope or taper).

The upper molding die 65 includes a first molding surface 68 and a second molding surface 69. The first molding surface 68 is connected to the lower part of the second molding surface 69. The first molding surface 68 is larger at the top and smaller at the bottom and has a taper and/or slope. The second molding surface 69 is vertically arranged.

The lower molding die 66 includes a molding cavity 70, and the molding cavity 70 includes a third molding surface 71 and a fourth molding surface 72. The third molding surface 71 is connected to the bottom of the fourth molding surface 72. The third molding surface 71 is larger at the top and smaller at the bottom and has a taper and/or slope. The third molding surface 71 corresponds to and matches the first molding surface 68. The fourth molding surface 72 is vertically arranged, and the fourth molding surface 72 corresponds to and matches the second molding surface 69.

For example, when making square cups and bowls, the four side surfaces are inclined surfaces with slopes, and the four side surfaces (inclined surfaces) are tapered curved surfaces. The bottom surface is usually a plane, and additional concave and convex embossing can also be provided on the plane.

Principle and effect: After the paper sheet between the upper forming mold 65 and the lower forming mold 66 (usually the paper sheet is pre-die-cut and creasing for smooth folding and forming) is in place, the upper forming mold 65 descends and presses the paper sheet into the forming mold cavity 70 of the lower forming mold 66. The whole paper sheet will be folded and formed into a paper cup body. The first forming surface 68 and the third forming surface 71 cooperate to fold out the main part of the paper cup body, and the second forming surface 69 and the fourth forming surface 72 cooperate to fold out the part to be rolled on the upper side of the main part of the paper cup body. The second forming surface 69 and the fourth forming surface 72 are respectively arranged vertically, so that the paper in the part to be rolled is in a vertical state (almost in an upright state, which can be regarded as a vertical state, with relatively no slope or taper). The paper in the part to be rolled in a vertical state is convenient for later rolling, the difficulty of rolling is relatively reduced, the rolling effect is relatively good, it is not easy to deform or wrinkle, and the requirements for paper materials are relatively low.

For example, the first roller paper guide pre-folding device 73 and the second roller paper guide pre-folding device are provided at the upper entrance of the molding cavity 70. The first roller paper guide pre-folding device 73 and the second roller paper guide pre-folding device 74 are arranged in staggered layers, that is, one is relatively on the top and the other is relatively on the bottom.

There are many ways of receiving cups, such as directly using a conveyor belt to output one by one or using a lifting material receiving platform to receive cups, etc. In this embodiment, the cup receiving device adopts a cup receiving and stacking device.

The cup receiving, material collecting and stacking device comprises a cup receiving and falling channel 51, which is vertically arranged so that cups and bowls can fall in the cup receiving and falling channel 51, and the upper end of the cup receiving and falling channel 51 is a translation cup feeding position 52, so that cups and bowls can be input into position from the translation cup feeding position 52, and after being input into position, the cups and bowls will fall into the cup receiving and falling channel 51 for cup receiving, material collecting and stacking.

The lifting and connecting cup-feeding air nozzle 53 can cooperate with sucking the cups and bowls in place at the translation cup feeding position 52 by descending. After sucking the cups and bowls, the lifting and connecting cup-feeding air nozzle 53 can descend again to cooperate with sending the sucked cups and bowls downward into the cup receiving and falling channel 51 to fall. The connecting and sending of cups is more efficient and stable. After the cups and bowls at the translation cup feeding position 52 are sucked by the lifting and connecting cup-feeding air nozzle 53, the device (such as a translation robot) that sends the cups and bowls to the translation cup feeding position 52 can retreat to process the next cup and bowl, and the cups and bowls are sucked and sent downward into the cup receiving and falling channel 51 more stably.

The cups and bowls are stacked on the lifting material receiving cup supporting component 54 one by one. The lifting material receiving cup supporting component 54 can also sort the stacked cups and bowls during the repeated lifting and lowering process (shaking up and down), and the lifting material receiving cup supporting component 54 gradually descends during the lifting and lowering process so that after the stacked cups and bowls form a set height, the lifting material receiving cup supporting component 54 will descend into place (i.e., land).

The bottom of the cup-receiving falling channel 51 is also provided with a cup-receiving component 55, which has an escape opening 56 for the lifting and lowering of the material-receiving cup-holder component 54. When the lifting and lowering material-receiving cup-holder component 54 is lowered into place, it will enter the escape opening 56, and the stacked cups and bowls on the lifting and lowering material-receiving cup-holder component 54 will be received by the cup-receiving component 55, completing the cup-receiving material stacking. At this time, the cups and bowls on the cup-receiving component 55 can be taken away or pushed away or transported away by a conveyor belt, and the lifting and lowering material-receiving cup-holder component will rise again to cooperate in receiving the cups and bowls.

Principle and effect: The cup receiving and stacking device can cooperate to collect and stack cups and bowls. It can adapt to cups and bowls that are translated and output by (such as a robot), and can efficiently receive cups through the lifting and connecting cup delivery air nozzle 53 and the lifting and connecting material cup support component 54. The efficiency is relatively high, and the lifting and connecting material cup support component 54 can continuously float and organize the cups and bowls during the descent process, so that the cups and bowls are stacked more neatly. The lifting and connecting cup delivery air nozzle 53 can cooperate with the translation cup feeding position 52 to connect and deliver cups, and cooperate with the lifting and connecting material cup support component 54 to stack cups and bowls in the cup receiving and falling channel 51.

For example, the lifting and connecting cup delivery air nozzle 53 is connected to the air nozzle lifting driving device 57, and the lifting and connecting cup delivery air nozzle 53 is driven to rise and fall by the air nozzle lifting driving device 57. The lifting and connecting cup receiving support cup component 54 is connected to the support cup servo motor 58, and the support cup servo motor 58 drives the lifting and connecting cup component 54 to rise and fall, and can additionally float (shake up and down) to arrange the cups and bowls during the overall lifting process.

For example, the nozzle lifting drive device 57 includes a double-stroke driving cylinder device (such as a double-stroke cylinder or a double-head cylinder or two connected cylinders) or includes a driving motor (the driving motor directly drives the lifting and connecting cup feeding nozzle 53 to double-stroke descend). The lifting and connecting cup receiving component 54 is connected to the cup supporting servo motor 58 through a screw rod and nut transmission mechanism. There are many transmission connection methods and they will not be described in detail.

The cup receiving and falling passage 51 is surrounded by a cup receiving rod and/or a cup receiving plate, and the cup receiving rod and/or the cup receiving plate surround the cup receiving and falling passage 51. If the cup receiving rod and/or the cup receiving plate are installed on the cup receiving bracket 59, it is convenient to install and set.

A translational cup outlet 60 may be provided beside the cup receiving and dropping channel 51, so that the cups and bowls (completely stacked) on the cup receiving component 55 can be discharged from the translational cup outlet 60. For example, the cup receiving component includes a translational cup outlet conveying component 61 (such as a conveyor belt), which can be used to translate and convey the cups and bowls out through the translational cup outlet 60 in cooperation with the cup receiving component.

In addition, the cup receiving and dropping channel 51 is also equipped with a front-to-back or left-to-right stacking side-shooting mechanism 62, which includes a side-shooting component and a side-shooting driving component (such as a cylinder or a motor, etc.), and the side-shooting component is connected to the side-shooting driving component, and the side-shooting driving component drives the side-shooting component to perform side-shooting, so as to perform side-shooting and sorting of the cups and bowls stacked in the cup receiving and dropping channel 51. For example, the front-to-back or left-to-right stacking side-shooting mechanism 62 is arranged above the cup-moving outlet 60 of the cup receiving and dropping channel 51, and the stacked cups and bowls can be sorted by side-shooting and subsequently go out of the cup-moving outlet 60.

The oil dipping device and preheating device are relatively mature technologies in paper cup forming machines, and existing conventional oil dipping devices and preheating devices can be used. In addition, if a lifting oil dipping component (which can be additionally equipped with a spring buffer) is used in the oil dipping device, the cup mouth oil dipping station 29 can also be equipped with a lifting oil dipping bottom support to cooperate with the lifting oil dipping component above it, and the lifting oil dipping bottom support is equipped with an oil dipping bottom support buffer return spring. The lifting oil dipping bottom support and the lifting oil dipping component can clamp the cup body and lower it for oil dipping. After the oil dipping is completed, it can rise and return to the initial position, which is convenient for oil dipping and translational conveying by the translational manipulator. For example, the preheating device may use a lifting preheating component (with a heating element (such as an electric heating wire or electric heating tube, etc.) and may be additionally equipped with a spring buffer), and the cup mouth preheating station 30 may also be equipped with a lifting preheating base to cooperate with the lifting preheating component above, and the lifting preheating base is equipped with a preheating base buffer return spring, and the lifting preheating base and the lifting preheating component can clamp the cup body and lower it for preheating, and the position where it is lowered is also equipped with a preheating unit (such as hot air blowing or steam) for additional heating of the cup mouth, and after the preheating is completed, it can rise and return to the initial position, which is convenient for preheating and translational conveying by the translational manipulator. Or, the lifting preheating component does not have a heating element and only cooperates to clamp the cup body and lower it, and the preheating unit performs preheating.
