Description

Technical Field

[0001] This application relates to the technical field of paper cup forming machines, and in particular to a paper cup conveying device for a medium-speed paper cup machine. Background Technology

[0002] In automated paper cup production, medium-speed paper cup machines need to efficiently transport formed paper cups to the stacking station for subsequent boxing or packaging. However, existing conveying and stacking devices have the following shortcomings: In traditional stacking and conveying methods, a pusher plate needs to push new paper cups into the bottom of a tightly stacked pile. The pusher plate directly moves the entire stack of paper cups upwards. With each additional paper cup, the friction and gravity that the pusher plate needs to overcome increases. This not only leads to increased energy consumption but also easily causes the bottom paper cups to deform due to continuous pressure, especially causing irreversible damage to the rolled edge structure. There are no buffer gaps between vertically stacked paper cups, and the rolled edges of the cup mouths become nested together under pressure, forming a mechanical lock. Subsequent packing requires an additional separation mechanism (such as air blowing or vibratory feeder), which increases the failure rate and may scratch the coating layer on the surface of the cup. Utility Model Content

[0003] In order to improve the problems of the bottom paper cups being easily deformed by pressure and the paper cups sticking tightly together, this application provides a paper cup conveying device for a medium-speed paper cup machine.

[0004] The paper cup conveying device for a medium-speed paper cup machine provided in this application adopts the following technical solution: A paper cup conveying device for a medium-speed paper cup machine includes a paper cup machine housing. A support column is fixedly connected to one side of the surface of the paper cup machine housing. A circular frame is fixedly connected to the outer surface of the support column. A circular arc frame for statically supporting paper cups is symmetrically fixedly connected to one side of the surface of the circular frame. Stacking plates, which are arranged alternately in a circular array with the circular arc frame and dynamically support the paper cups, are symmetrically and movably connected to the outside of the circular frame. A first hanger and a second hanger for preventing the paper cups from being tightly connected are linearly arrayed on the outside of the stacking plates and the circular arc frame, respectively. An adjusting block for changing the distance between the first hanger and the second hanger is slidably connected through the inside of the stacking plates and the circular arc frame.

[0005] By adopting the above technical solution, the arc-shaped frame provides stable static support, ensuring the paper cups remain fixed in position during non-moving phases. The stacking plate provides dynamic lifting support, allowing the paper cups to be lifted or lowered as a whole when needed. The alternating circumferential arrays of both ensure even distribution of support points, balanced force on the paper cups, and smoother conveying. The first and second hangers are respectively installed on the stacking plate and the arc-shaped frame, inserting between or along the edges of the paper cups to effectively physically separate adjacent cups, preventing them from sticking together tightly due to static electricity, shape, or compression, ensuring smooth separation and conveying. An adjusting block slides through the stacking plate and the arc-shaped frame and is associated with the hangers. By moving the adjusting block, the distance between the first and second hangers can be changed. This allows the same device to easily adapt to paper cups of different heights or diameters, greatly improving the versatility and flexibility of the equipment without requiring replacement of major components.

[0006] Preferably, the outer surface of the ring frame is movably connected to a ring plate, and a connecting block that is fixedly connected to the surfaces of two stacked plates is symmetrically fixedly connected to one side of the surface of the ring plate. A limiting post that is symmetrically fixedly connected to the upper surface of the ring frame and is slidably connected through the ring plate.

[0007] By adopting the above technical solution, the annular plate connects two stacked plates simultaneously via connecting blocks. When the electric actuator drives the annular plate, it ensures that the two stacked plates rise and fall synchronously and consistently, with precise and reliable action, preventing paper cups from tilting or jamming. The limiting post penetrates the annular plate, playing a role in precise guidance and limiting rotation during the raising and lowering of the annular plate. This ensures that the stacked plates can only move in the vertical direction, without twisting or shifting, maintaining the stability and positional accuracy of the entire support structure.

[0008] Preferably, a torsion spring is fitted at one end of the adjusting block, one side of the surface of the first bracket is fixed to the surface of the torsion spring near the stacking plate, one side of the surface of the second bracket is fixed to the surface of the torsion spring near the arc frame, and a limit block is fixedly connected to the end surface of the adjusting block near the torsion spring.

[0009] By adopting the above technical solution, one end of the torsion spring is fixed to the hanger, and the other end acts on the adjusting block. When the adjusting block is moved to change the hanger spacing, the torsion spring is twisted and stores energy. After the adjusting block is released, the torque of the torsion spring automatically pulls the adjusting block back and stabilizes it in the preset position, simplifying operation and ensuring reliable positioning. The limiting block is fixedly connected to the end of the adjusting block near the torsion spring. It limits the rotation angle of the adjusting block under the action of the torsion spring, preventing excessive rotation that could lead to mechanism failure or damage, and also defines the adjustment range of the hanger spacing.

[0010] Preferably, both ends of the stacking plate and the arc frame are symmetrically provided with circular grooves, the inner walls of the circular grooves are symmetrically provided with side grooves, a fixed column is slidably connected inside the circular groove, a side plate that is adapted to the size of the side groove and slides inside the side groove is fixedly connected to the outer surface of the fixed column, and a spring is fixedly connected between the surface of the side plate and the inner wall of the side groove.

[0011] By adopting the above technical solution, the fixing column is used to lock the position of the adjusting block.

[0012] Preferably, both ends of the adjusting block are symmetrically provided with linearly arrayed limiting grooves that are slidably connected to the surface of the fixed column.

[0013] By adopting the above technical solution, the fixing column is used to be inserted into one of the limiting grooves to fix it.

[0014] Preferably, the stacking plate and the end of the fixed column inside the arc frame away from the adjusting block are respectively fixedly connected to a second connecting plate, and the end of the stacking plate and the end of the adjusting block inside the arc frame away from the torsion spring are respectively fixedly connected to a first connecting plate.

[0015] By adopting the above technical solution, the stacking plate and all the adjusting blocks on the arc frame can be moved synchronously by operating the first connecting plate. Correspondingly, the second connecting plate ensures that all the fixed columns on the stacking plate and the arc frame also change in linkage. This greatly simplifies the adjustment process. The operator only needs to operate in one position to adjust the distance between all the first and second hangers at once, ensuring the consistency of the adjustment of all the first and second hangers and improving efficiency.

[0016] Preferably, the inside of the paper cup machine housing is provided with a conveyor plate, and a pusher column located below the conveyor plate is slidably connected through the inside of the paper cup machine housing.

[0017] By adopting the above technical solutions, the conveyor plate and pusher column realize the automated and continuous transfer of paper cups from the conveying device to the subsequent processes, thereby improving the overall production efficiency.

[0018] Preferably, an electric actuator is fixedly connected to one side of the surface of the support column, and the movable end of the electric actuator passes through the interior of the circular frame and is fixed to the surface of the circular plate.

[0019] By adopting the above technical solution, the electric actuator provides controllable and stable linear power for the lifting and lowering of the circular plate. The electric actuator is easy to control in terms of stroke, speed and start / stop, making the lifting and lowering action of the stacking plate precise, reliable and programmable, perfectly adapting to the production cycle of medium-speed paper cup machines.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By alternating the static first hanger of the stacking plate and the dynamic second hanger of the arc frame, a stepped transfer of paper cups from the lowest layer to the highest layer is achieved. Each time the arc frame is raised, all the paper cups hanging on the first hanger are raised to the next layer above the second hanger of the stacking plate. After the arc frame is reset downwards, the lowest first hanger and the lowest second hanger of the stacking plate are empty. At this time, the pusher only needs to overcome the weight and friction of one paper cup, and the pusher does not need to push the entire stack of paper cups that are already hanging above, thus avoiding deformation of the bottom paper cups due to continuous pressure.

[0021] 2. The first and second hangers are linearly arrayed and equidistantly distributed on the stacking plate and the arc frame, with each paper cup suspended by only one layer of the first and second hangers. There is no direct vertical pressure between the paper cups, only slight contact. Precise spacing is provided between the first and second hangers, ensuring that the paper cups maintain their shape, remain independent, and are easily separated (simply lift them upwards to detach them from the first and second hangers), greatly improving the efficiency and reliability of subsequent automated cup retrieval.

[0022] 3. The positions of the first and second hangers can be changed by moving the adjusting block. The connecting plate, the fixed column, and the limiting groove enable locking and unlocking of the positions. After unlocking, the adjusting block can be moved as a whole to change the distance between the first and second hangers, and then locked again. One set of equipment can handle paper cups of different heights (different edge curling distances). Only the distance between the first and second hangers needs to be adjusted to match their edge curling positions, which improves the versatility and flexibility of the equipment.

[0025] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0026] This application discloses a paper cup conveying device for a medium-speed paper cup machine.

[0027] Reference Figure 1 , Figure 2 A paper cup conveying device for a medium-speed paper cup machine includes a paper cup machine housing 1. The upper surface of the paper cup machine housing 1 is fixed to the lower surface of a support column 21 at its middle position. The top outer surface of the support column 21 is fixed to the interior of one end of a circular ring frame 2. The support column 21 penetrates the interior of the circular ring frame 2. The upper surface of the circular ring frame 2 is fixed to the lower surface of two arc-shaped frames 5. The two arc-shaped frames 5 are symmetrically arranged and parallel to the support column 21. The arc-shaped frames 5 are used for statically supporting paper cups. The top of the circular ring frame 2 is connected to two stacking plates 4. The two stacking plates 4 are symmetrically arranged and perpendicular to the support column 21. The stacking plates 4 and the arc frame 5 are arranged in a circumferential array and are alternately distributed. The stacking plates 4 are used to dynamically support the paper cups. The paper cup machine housing 1 is provided with a conveying plate 11 inside. The paper cup machine housing 1 is located at the bottom of the ring frame 2 and is slidably connected to the push column 12. The push column 12 is located below the conveying plate 11. The conveying plate 11 is used to rotate and convey the formed paper cups located directly below the ring frame 2 and directly above the push column 12.

[0028] The circular arc frame 5 is fixed to the circular ring frame 2, while the stacking plate 4 is not fixed to the circular ring frame 2. When the stacking plate 4 moves upward, it drives all the paper cups to move upward, realizing the step-like transfer of paper cups from the lowest layer to the higher layer. The empty lowest layer is used to stack new paper cups. The push column 12 moves upward to push the paper cups located in the conveyor plate 11 into the bottom of the stacking plate 4 and the circular arc frame 5. The push column 12 only needs to overcome the weight and friction of one paper cup, and the push column 12 does not need to push the whole stack of paper cups that are already hanging above, avoiding the deformation of the bottom paper cups due to continuous pressure.

[0029] Reference Figure 4 , Figure 5The stacking plate 4 is provided with a first hanger 6 on its outside, and the arc frame 5 is provided with a second hanger 7 on its outside. The first hanger 6 and the second hanger 7 are linearly arrayed. The array arrangement of the first hanger 6 and the second hanger 7 is used to prevent the paper cups from being tightly connected. The interior of the stacking plate 4 and the arc frame 5 are slidably connected to the surface of the adjusting block 8. The adjusting block 8 is used to change the distance between the first hanger 6 and the second hanger 7. The gap between the first hanger 6 and the second hanger 7 can both be set to 5mm. This can prevent the paper cups from being tightly connected and ensure that the paper cups are not easy to slip off, avoiding friction.

[0030] The second hanger 7, connected to the arc frame 5, is fixed in position. The first hanger 6 moves as the stacking plate 4 moves. The conveyor plate 11 rotates to transport the formed paper cup to the bottom of the ring frame 2. The pusher 12 pushes the paper cup from below into the middle of the circle formed by the stacking plate 4 and the arc frame 5. The top edge of the paper cup is provided with a rolled edge, which is raised. As the paper cup moves upward, it will squeeze the first hanger 6 and the second hanger 7 to rotate. When the rolled edge of the top of the paper cup exceeds the first hanger 6 and the second hanger 7, the first hanger 6 and the second hanger 7 rotate to be below the edge of the paper cup and hang the paper cup. When the first hanger 6 moves upward, it will drive the paper cup to move upward. The movement of the paper cup will squeeze the second hanger 7 on the second layer. When the first hanger 6 stops moving, the paper cup is hung on the second hanger 7 on the second layer. Then the stacking plate 4 drives the first hanger 6 to reset back to its original position, waiting for the next rotation of the conveyor plate 11 to send the paper cup in.

[0031] Reference Figure 3 , Figure 4 The top of the ring frame 2 is movably connected to the bottom of the ring plate 3. The inner side of the ring plate 3 is fixed to the surface of the two connecting blocks 32. The sides of the two connecting blocks 32 that are close to each other are fixed to the outer surfaces of the two stacking plates 4 respectively. The upper surface of the ring frame 2 is fixed to the lower surface of the two limiting posts 33. The two limiting posts 33 are slidably connected inside the ring plate 3. The side of the support post 21 that is close to the conveying plate 11 is fixed to the mounting end of the electric push rod 31. The output end of the electric push rod 31 passes through the interior of the ring frame 2. The output end of the electric push rod 31 is fixed to the lower surface of the ring plate 3.

[0032] When the pusher 12 pushes the paper cup into the stacking plate 4 and the arc frame 5, and the paper cup is hung in the lowest layer of the first hanger 6 and the second hanger 7, the electric push rod 31 starts to extend its output end, causing the annular plate 3 to move upward. The annular plate 3 slides on the outer surface of the limiting post 33. When the annular plate 3 moves, it causes the connecting block 32 to move. When the connecting block 32 moves, it causes the two stacking plates 4 to move upward, realizing the step-like transfer of the paper cup from the lowest layer to the higher layer. The adjusting block 8 has a notch at the end near the paper cup, and a cylinder is formed in the middle of the notch. The cover is equipped with a torsion spring 81. The bottom end of the first hanger 6 is fixed to one end of the torsion spring 81 near the stacking plate 4. The first hanger 6 is initially set at an angle. The other end of the torsion spring 81 abuts against the inside of the notch of the adjusting block 8. The bottom end of the second hanger 7 is fixed to one end of the torsion spring 81 near the arc frame 5. The surface of the adjusting block 8 is fixed to the surface of the limiting block 82. The limiting block 82 is set at one end near the torsion spring 81. The second hanger 7 abuts against the inside of the limiting block 82. The limiting block 82 is used to limit the initial position of the second hanger 7 to prevent the paper cup from being squeezed.

[0033] Reference Figure 4 , Figure 5 When the pusher 12 pushes the paper cup into the stacking plate 4 and the arc frame 5, and the paper cup is hung in the lowest layer of the first hanger 6 and the second hanger 7, the electric pusher 31 starts to extend the output end and drives the annular plate 3 to move upward. The annular plate 3 slides on the outer surface of the limiting post 33. When the annular plate 3 moves, it drives the connecting block 32 to move. When the connecting block 32 moves, it drives the two stacking plates 4 to move upward, realizing the step-like transfer of the paper cup from the lowest layer to the higher layer. When the paper cup squeezes the first hanger 6 and the second hanger 7, it will cause the torsion spring 81 to deform. When it exceeds the first hanger 6 and the second hanger 7, it will rebound and hold the paper cup.

[0034] Both ends of the stacking plate 4 and the arc frame 5 are provided with circular grooves 83, which are symmetrically arranged inside the stacking plate 4 and the arc frame 5. Each circular groove 83 has two side grooves 84 on its inner wall, symmetrically arranged on both sides of the circular groove 83. The interior of the circular groove 83 is slidably connected to the fixing post 85. The outer surface of the fixing post 85, near the side groove 84 at the middle of the stacking plate 4, is fixed to the inner side of the side plate 86. The side plate 86 is penetrated by the fixing post 85 and slides against the inner wall of the side groove 84. The dimensions of the side plate 86 are matched with the dimensions of the side groove 84 without gaps, to prevent [missing information] when the side plate 86 slides. The side groove 84 is offset, and one end of the side plate 86 away from the side plate 86 is fixed to one end of the spring 87. The other end of the spring 87 is fixed to the surface of the side plate 86. Multiple limiting grooves 88 are provided at both ends of the adjusting block 8. The limiting grooves 88 are distributed in a parallel line array along the adjusting block 8. The inner wall of the limiting groove 88 is slidably connected to the outer surface of the fixing column 85. The size of the limiting groove 88 is adapted to the size of the fixing column 85 to improve the stability of the paper cup support. The fixing columns 85 on both sides of each stacking plate 4 and the arc frame 5 are respectively fixed to a connecting plate 810. The adjusting block 8 inside each stacking plate 4 and the arc frame 5 is respectively fixed to a connecting plate 89.

[0035] Reference Figure 6 , Figure 7 Initially, the fixed column 85 is located inside the limiting groove 88, and the spring 87 is in an uncompressed state. When it is necessary to adjust the distance between the first hanger 6 and the second hanger 7 of each layer, the operator pushes the connecting plate 2 810 outward. The connecting plate 2 810 drives all the fixed columns 85 to move out of the limiting groove 88 simultaneously. When the fixed column 85 moves, it drives the side plate 86 to squeeze the spring 87. At this time, the adjusting block 8 is not locked. The operator moves the connecting plate 1 89, thereby driving all the adjusting blocks 8 to move synchronously for adjustment, avoiding the distance difference between each adjusting block 8. After the position of the adjusting block 8 is adjusted, the operator releases the connecting plate 2 810. The connecting plate 2 810 drives the fixed column 85 into the limiting groove 88 through the elastic force of the spring 87, thereby locking the adjusting block 8. The size of the limiting groove 88 and the fixed column 85 can be set according to the actual situation. The adjustable range of the spacing of the adjusting block 8 is designed to be 50mm-150mm, which can be adapted to most paper cups produced by medium-speed paper cup machines.

[0036] Among them, the electric actuator 31 is existing technology, and its structural principle will not be described in detail. The electric actuator 31 can be a Limtech mini electric actuator 31, LAM model, rated power: 50W, maximum load capacity: 200N, stroke range: 200mm-500mm, which meets the requirements of precision control. The electric actuator 31 can be controlled by a microcontroller (MCU) in conjunction with PWM signal to adjust the speed and stroke, ensuring that the lifting and lowering action of the stacking board 4 is accurate and smooth. The signal line is connected to the control board MCU, and the MCU outputs PWM signal to the motor driver to drive the DC motor of the electric actuator 31. The motor shaft is connected to the push rod screw through a coupling to realize the telescopic movement. The control accuracy of the electric actuator 31 is 1mm to ensure the accuracy of each lifting and lowering action and avoid errors in the process of stacking paper cups.

[0037] The implementation principle of the paper cup conveying device of a medium-speed paper cup machine according to an embodiment of this application is as follows: After the paper cup is formed, it is rotated to the top of the push column 12 by the conveying plate 11. It is pushed into the interior of the stacking plate 4 and the arc frame 5 by the push column 12. When the paper cup is pushed in, the edge of the paper cup will squeeze the lowest first hanger 6 and the second hanger 7. When the paper cup exceeds the lowest first hanger 6 and the second hanger 7, it stops moving. At this time, the first hanger 6 and the second hanger 7 are not squeezed. The first hanger 6 and the second hanger 7 extend and hang on the edge of the paper cup. The electric push rod 31 extends and drives the ring plate 3 to move upward. The ring plate 3 drives the stacking plate 4 and the first hanger 6 fixed thereto to move upward, thereby driving the paper cup to move upward and squeeze the second layer second hanger 7 fixed to the arc frame 5, hanging the paper cup on the second layer first hanger 6 of the stacking plate 4. Then the stacking plate 4 drives the first hanger 6 to move downward and reset. The second formed paper cup is hung on the lowest first hanger 6 and the second hanger 7 by the push column 12.

[0038] By alternating the static first hanger 6 of the stacking plate 4 and the dynamic second hanger 7 of the arc frame 5, the paper cups are transferred in a stepped manner from the lowest layer to the highest layer. Each time the arc frame 5 is raised, all the paper cups hanging on the first hanger 6 are raised to the next layer above the second hanger 7 of the stacking plate 4. After the arc frame 5 is reset downwards, the lowest layer first hanger 6 and the lowest layer second hanger 7 of the stacking plate 4 are empty. At this time, the push column 12 only needs to overcome the weight and friction of one paper cup, and the push column 12 does not need to push the entire stack of paper cups that are already hung above, thus avoiding the deformation of the bottom layer paper cups due to continuous pressure. Then the stacking plate 4 drives all the formed paper cups to move upwards again. The first hanger 6 and the second hanger 7 are linearly arrayed and equidistantly distributed on the stacking plate 4 and the arc frame 5, and each paper cup is suspended by only one layer of the first hanger 6 and the second hanger 7. There is no direct vertical pressure between the paper cups, only slight contact. The first hanger 6 and the second hanger 7 provide precise spacing, keeping the paper cups in good shape and independent of each other. Separation is very easy (simply lift upwards to detach from the first hanger 6 and the second hanger 7), greatly improving the efficiency and reliability of subsequent automated cup retrieval.

[0039] Each first hanger 6 and second hanger 7 is adjustable within the stacking plate 4 and the arc frame 5. By pushing open the two connecting plates 810, the fixing post 85 can be pushed out of the limiting groove 88, unlocking the adjusting block 8 connecting the first hanger 6 and the second hanger 7. The adjusting block 8 can be adjusted according to the size of the paper cup, and is fixed by inserting the fixing post 85 into the corresponding movable limiting groove 88. Each adjusting block 8 connected to the first hanger 6 and the second hanger 7 is fixed by a connecting plate 89. Adjusting the position of the first hanger 6 and the second hanger 7 by moving the adjusting block 8 allows the connecting plate 810, the fixing post 85, and the limiting groove 88 to achieve locking and unlocking. After unlocking, the adjusting block 8 can be moved as a whole to change the distance between the first hanger 6 and the second hanger 7, and then relocked. One set of equipment can handle paper cups of different heights (different edge curling distances) by simply adjusting the distance between the first hanger 6 and the second hanger 7 to match their edge curling positions, improving the versatility and flexibility of the equipment.
