Description

Technical Field

[0001] The present invention relates to the technical field of paper cup production, and specifically to an automatic palletizing device for paper cup production. Background Art

[0002] Paper cups are a widely used disposable container, mainly made of coated paper or laminated paper. By coating materials such as polyethylene on the surface of the base paper or through hot-pressing to composite plastic films, it has good waterproof performance to prevent liquid leakage. After the production of paper cups is completed, palletizing of paper cups is required. A paper cup palletizing device is a specialized automatic mechanical device for orderly stacking and arranging paper cups. It usually consists of multiple parts. First, there is a conveying device that can stably and efficiently transport paper cups from the production line to the palletizing area to ensure the continuous supply of paper cups. Secondly, there is a palletizing execution mechanism that precisely operates according to a preset program. It can stack paper cups neatly together according to different paper cup specifications and palletizing patterns to improve space utilization. Finally, there is also a control system that has a flexible parameter setting function. Operators can easily adjust parameters such as the number of layers, columns, and spacing of palletizing.

[0003] During the palletizing process of paper cups, they are prone to deviation, resulting in uneven palletizing. The texture of paper cups is not hard enough, and they are easily damaged by collision during transportation. Therefore, we have proposed an automatic palletizing device for paper cup production. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: An automatic palletizing device for paper cup production, including a workbench. One side of the top of the workbench is fixedly connected with a fixing plate. One side of the fixing plate is provided with a round hole one. The inner wall of the round hole one is fixedly connected with a feeding device. A chute is provided on the top of the workbench on the side away from the fixing plate. One side of the workbench is fixedly connected with a motor. The driving shaft of the motor is fixedly connected with a threaded rod. A conveying device is slidably connected to the inner wall of the chute. A through hole is provided at the bottom of the inner wall of the chute. A discharging device is fixedly connected to the bottom of the workbench. Supporting legs are fixedly connected to the bottom of the workbench. One end of the threaded rod penetrates through the workbench and is threadedly connected with the workbench. One end of the threaded rod penetrates through the conveying device and is threadedly connected with the conveying device.

[0005] The feeding device includes a conveying pipe. One end of the conveying pipe is fixedly connected with a semi-open pipe. A spring is fixedly connected to the inner side of the semi-open pipe. One end of the spring away from the semi-open pipe is fixedly connected with a push plate. As a component directly acting on the paper cup, the push plate can apply a thrust to the paper cup under the drive of the spring, pushing the paper cup into the conveying pipe from the semi-open pipe to realize the position transfer of the paper cup. A round rod is fixedly connected to the side of the push plate close to the spring. A elastic rope is fixedly connected to the side of the push plate close to the spring. The elastic rope generates elastic deformation when the spring rebounds. When the maximum elastic deformation is reached, it generates a resistance to the spring, effectively preventing the rebound thrust of the spring from being too large and damaging the paper cup, and protecting the paper cup from excessive impact through its own elastic buffering characteristics. A magnetic block is fixedly connected to the side of the round rod away from the push plate. A U-shaped rod is fixedly connected to the outside of the semi-open pipe. An electromagnetic chuck is fixedly connected to the inner side of the U-shaped rod. A ventilation ring plate is sleeved and communicated with the conveying pipe. The ventilation ring plate receives the air flow from the three-way pipe and distributes it evenly, ensuring that the air flow has a relatively uniform distribution and a stable flow rate when entering the inclined air pipe. An inclined air pipe is communicated with the inner side of the ventilation ring plate. The inclined air pipe guides the air flow to enter the conveying pipe in an inclined manner, changing the direction and flow rate of the air flow. It can not only form a thrust on the paper cup, but also avoid the paper cup getting stuck in the conveying pipe through the action of the inclined thrust. An elastic wave plate is fixedly connected to the side of the ventilation ring plate close to the semi-open pipe. The elastic wave plate prevents the uneven thrust of the push plate on the paper cup from pushing the paper cup out of the semi-open pipe. A three-way pipe is communicated with the ventilation ring plate. One end of the three-way pipe away from the ventilation ring plate is communicated with an air pump. One side of the ventilation ring plate is fixedly connected to the inner wall of the first round hole. One side of the air pump is fixedly connected to one side of the fixed plate. One end of the round rod penetrates through the semi-open pipe and is slidably connected with the semi-open pipe. One end of the elastic rope away from the push plate is fixedly connected to the inner side of the semi-open pipe.

[0006] Further, the conveying device includes a sliding plate. A deviation prevention mechanism is fixedly connected to the top of the sliding plate. Circular holes II are formed in both the top and bottom of the sliding plate. A rectangular groove is formed in one side of the sliding plate. One side of the inner wall of the rectangular groove is fixedly connected with a telescopic spring. When the baffle is subjected to pressure, the telescopic spring is compressed, absorbing the impact force received by the baffle, playing a role in buffering and protecting the system, avoiding component damage caused by impact, and at the same time providing an elastic restoring force for the movement of the baffle. One end of the telescopic spring away from the inner wall of the rectangular groove is fixedly connected with a baffle. The baffle plays a limiting role. When the sliding plate is about to move to the top, it contacts the inner wall of the chute and moves inward by applying pressure to the telescopic spring. Its moving position ensures that the paper cup can smoothly fall from the circular hole II through the circular hole III. A circular hole III is formed in the top of the baffle. One side of the sliding plate is slidably connected with the inner wall of the chute. There are two deviation prevention mechanisms, and the two deviation prevention mechanisms are distributed on both sides of the center position of the top of the sliding plate. The deviation prevention mechanism includes an arc-shaped column. During the falling process of the paper cup, the inclined arc-shaped block provides an annular fixed channel for the paper cup, preventing the paper cup from shifting during the falling process, so that the paper cup enters the subsequent palletizing in the correct posture. A rectangular hole is formed in the top of the arc-shaped column. One side of the inner wall of the rectangular hole is fixedly connected with a connecting rod. The connecting rod away from the rectangular hole is fixedly connected with an inclined arc-shaped block. One side of the bottom of the inner wall of the rectangular hole is fixedly connected with an electric push rod. The movable end of the electric push rod is fixedly connected with an arc-shaped rod. The electric push rod moves according to the size of the paper cup opening, drives the arc-shaped rod to adjust the position, and precisely fixes the paper cup, realizing the adaptive palletizing of paper cups of different sizes, being able to flexibly adjust according to the size of the paper cup. The arc-shaped rod fixes the cup mouth of the paper cup, ensuring that the paper cup is fixed during the palletizing process, preventing the paper cup from tipping or misaligning during the palletizing process, ensuring the quality of the paper cup palletizing. At the same time, it prevents the baffle from shifting the palletized paper cups during movement. The bottom of the arc-shaped column is fixedly connected with the top of the sliding plate. There are multiple connecting rods, and the multiple connecting rods are distributed on one side of the inner wall of the rectangular hole.

[0007] Furthermore, the discharging device includes an arc-shaped elbow pipe. One end of the arc-shaped elbow pipe is fixedly connected with an annular plate. On the side of the annular plate away from the arc-shaped elbow pipe, an L-shaped platform is fixedly connected. An arc-shaped groove is formed in the top of the L-shaped platform. A circular groove is formed in one side of the inner wall of the arc-shaped groove. A buffer spring is fixedly connected to one side of the inner wall of the arc-shaped groove. When the bottom of the paper cup contacts the T-shaped rod, impacted by the falling of the paper cup, the buffer spring is compressed. The buffer spring serves as a buffer component to absorb the impact force when the paper cup falls, convert the impact force into elastic potential energy, thereby buffering the impact force of the paper cup, preventing the bottom of the paper cup from being damaged due to the impact, and protecting the integrity of the paper cup. One end of the buffer spring away from the inner wall of the arc-shaped groove is fixedly connected with a T-shaped rod. An inclined sliding platform is fixedly connected to the inner wall of the arc-shaped groove. The inner slope of the inclined sliding platform fits the slope of the paper cup wall. When the paper cup slides onto it, it can make the paper cup return to the horizontal and transverse state and reduce the speed of the paper cup, playing a role in adjusting the state of the paper cup and buffering the speed. A semi-circular rod is fixedly connected to the top of the inclined sliding platform. The semi-circular rod fixes the paper cup to ensure that the paper cup maintains a stable position in subsequent operations. A rotating sleeve block is sleeved on and rotatably connected to the semi-circular rod. The rotating sleeve block prevents the paper cup from being damaged due to excessive friction on the cup wall when fixed by the semi-circular rod. Through its own rotating characteristics, it reduces the friction between the paper cup and the semi-circular rod and protects the surface of the paper cup from being damaged. The end of the arc-shaped elbow pipe away from the annular plate is fixedly connected to the bottom of the workbench. One end of the T-shaped rod is slidably connected to the inner wall of the circular groove.

[0008] The present invention provides an automatic palletizing device for paper cup production. It has the following beneficial effects:

[0009] 1. In this automatic palletizing device for paper cup production, a push plate is provided as a component directly acting on the paper cup. It can apply a thrust to the paper cup under the drive of a spring, push the paper cup from the semi-open pipe into the conveying pipe, and realize the position transfer of the paper cup. The elastic cord generates elastic deformation when the spring rebounds. When the maximum elastic deformation is reached, it generates a resistance to the spring, effectively preventing the excessive rebound thrust of the spring from damaging the paper cup. Through its own elastic buffering characteristics, it protects the paper cup from excessive impact. During the falling process of the paper cup, the inclined arc block provides an annular fixing channel for the paper cup, preventing the paper cup from shifting during the fall and enabling the paper cup to enter the subsequent palletizing in the correct posture. The inner slope of the inclined sliding platform fits the slope of the paper cup wall. When the paper cup slides onto it, it can make the paper cup return to the horizontal and transverse state and reduce the speed of the paper cup, playing a role in adjusting the state of the paper cup and buffering the speed.

[0010] 2. The automated palletizing equipment for paper cup production is provided with a feeding device. The push plate, as a component directly acting on the paper cups, can apply a thrust to the paper cups under the drive of the spring, pushing the paper cups from the semi-open tube into the conveying tube to achieve the position transfer of the paper cups. The elastic cord undergoes elastic deformation when the spring rebounds. When the maximum elastic deformation is reached, it generates a resistance to the spring, effectively preventing the excessive rebound thrust of the spring from damaging the paper cups. Through its own elastic buffering characteristics, it protects the paper cups from excessive impact. The ventilation ring plate receives the air flow from the tee pipe and distributes it evenly, ensuring that the air flow has a relatively uniform distribution and a stable flow rate when entering the inclined air duct. The inclined air duct guides the air flow to enter the conveying tube in an inclined manner, changing the direction and flow rate of the air flow. It can not only form a thrust on the paper cups but also avoid the paper cups getting stuck in the conveying tube through the action of the inclined thrust. The elastic wave plate prevents the uneven thrust of the push plate on the paper cups from pushing the paper cups out of the semi-open tube.

[0011] 3. The automated palletizing equipment for paper cup production is provided with a conveying device. During the falling process of the paper cups, the inclined arc blocks provide an annular fixed channel for the paper cups to prevent the paper cups from shifting when falling, enabling the paper cups to enter the subsequent palletizing in the correct posture. The electric push rod moves according to the opening size of the paper cups, driving the arc-shaped rod to adjust its position to precisely fix the paper cups, achieving the adaptive palletizing of paper cups of different sizes and being able to flexibly adjust according to the size of the paper cups. The arc-shaped rod fixes the cup mouth of the paper cups to ensure the fixation of the paper cups during palletizing, preventing the paper cups from toppling or being misaligned during palletizing, and ensuring the quality of paper cup palletizing. At the same time, it prevents the baffle from causing the offset of the palletized paper cups when moving. The baffle plays a limiting role. When the sliding plate is about to move to the top, it contacts the inner wall of the chute and moves inward by applying pressure to the telescopic spring. Its moving position ensures that the paper cups can smoothly fall from the round hole two through the round hole three. The telescopic spring is compressed when the baffle is under pressure, absorbing the impact force received by the baffle, playing a buffering and protecting role for the system, avoiding component damage caused by impact, and at the same time providing an elastic restoring force for the movement of the baffle.

[0012] 4. The automatic palletizing equipment for paper cup production is provided with a discharging device. The inner slope of the inclined slide is fitted with the slope of the paper cup wall. When the paper cup slides onto it, the paper cup can be restored to a horizontal lateral state and its speed can be reduced, playing the role of adjusting the state of the paper cup and buffering the speed. When the bottom of the paper cup contacts the T-shaped rod, it is impacted by the falling of the paper cup, causing the buffer spring to be compressed. The buffer spring, as a buffer component, absorbs the impact force when the paper cup falls, converts the impact force into elastic potential energy, thereby buffering the impact force of the paper cup and preventing the bottom of the paper cup from being damaged due to the impact, protecting the integrity of the paper cup. The semi-circular rod fixes the paper cup to ensure that the paper cup maintains a stable position in subsequent operations. The rotating sleeve block prevents the paper cup from being damaged due to excessive friction on the cup wall when it is fixed by the semi-circular rod. Through its own rotation characteristics, it reduces the friction between the paper cup and the semi-circular rod and protects the surface of the paper cup from being damaged.

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] The first embodiment, please refer to Figures 1 - 4 , the present invention is an automatic palletizing device for paper cup production, including a workbench 1. One side of the top of the workbench 1 is fixedly connected with a fixed plate 2. One side of the fixed plate 2 is provided with a first round hole 3. The inner wall of the first round hole 3 is fixedly connected with a feeding device 4. One side of the top of the workbench 1 away from the fixed plate 2 is provided with a chute 5. One side of the workbench 1 is fixedly connected with a motor 6. The driving shaft of the motor 6 is fixedly connected with a threaded rod 7. The inner wall of the chute 5 is slidably connected with a conveying device 8. The bottom of the inner wall of the chute 5 is provided with a through hole 9. The bottom of the workbench 1 is fixedly connected with a discharging device 10. The bottom of the workbench 1 is fixedly connected with support legs 11. One end of the threaded rod 7 penetrates through the workbench 1 and is threadedly connected with the workbench 1. One end of the threaded rod 7 penetrates through the conveying device 8 and is threadedly connected with the conveying device 8;

[0024] The feeding device 4 includes a conveying pipe 41. One end of the conveying pipe 41 is fixedly connected with a semi-open pipe 42. A spring 43 is fixedly connected to the inner side of the semi-open pipe 42. One end of the spring 43 away from the semi-open pipe 42 is fixedly connected with a push plate 44. A round rod 45 is fixedly connected to the side of the push plate 44 close to the spring 43. An elastic cord 46 is fixedly connected to the side of the push plate 44 close to the spring 43. A magnetic block 47 is fixedly connected to the side of the round rod 45 away from the push plate 44. A U-shaped rod 48 is fixedly connected to the outer side of the semi-open pipe 42. An electromagnetic chuck 49 is fixedly connected to the inner side of the U-shaped rod 48. A ventilation ring plate 410 is sleeved and communicated with the conveying pipe 41. An inclined air pipe 411 is communicated with the inner side of the ventilation ring plate 410. An elastic wave plate 412 is fixedly connected to the side of the ventilation ring plate 410 close to the semi-open pipe 42. A three-way pipe 413 is communicated with the ventilation ring plate 410. One end of the three-way pipe 413 away from the ventilation ring plate 410 is communicated with an air pump 414. One side of the ventilation ring plate 410 is fixedly connected to the inner wall of the round hole 1 3. One side of the air pump 414 is fixedly connected to the side of the fixing plate 2. One end of the round rod 45 penetrates through the semi-open pipe 42 and is slidably connected with the semi-open pipe 42. One end of the elastic cord 46 away from the push plate 44 is fixedly connected to the inner side of the semi-open pipe 42. When in use, the paper cup horizontally falls onto the inner wall of the semi-open pipe 42. The power supply inside the electromagnetic chuck 49 is turned on, and the magnetic block 47 is moved towards the electromagnetic chuck 49 by magnetic force. Since the magnetic block 47 is connected to the round rod 45 and the round rod 45 is connected to the push plate 44, the movement of the magnetic block 47 drives the round rod 45 and the push plate 44 to move synchronously. During the movement of the push plate 44, the spring 43 connected to the push plate is subjected to the force transmitted by the push plate and begins to be compressed. As the magnetic block 47 continues to move, the spring 43 continues to be compressed and stores elastic potential energy. When the magnetic block 47 drives the push plate 44 to move a certain distance, the power supply of the electromagnetic chuck 49 is disconnected. At this time, the magnetic force generated by the electromagnetic chuck quickly disappears, and the pressure exerted on the spring 43 by the push plate 44 also disappears. The spring begins to rebound. During the rebound process, the spring 43 converts the stored elastic potential energy into kinetic energy, drives the push plate 44 to move towards the paper cup, and exerts a thrust on the paper cup. Under the action of this thrust, the paper cup enters the conveying pipe 41 from the inner wall of the semi-open pipe 42. At the same time as the spring 43 rebounds, the elastic cord 46 connected to the push plate 44 or related structures also undergoes elastic deformation together. As the spring 43 rebounds, the deformation degree of the elastic cord 46 gradually increases. When the elastic cord 46 reaches its maximum elastic deformation, it will generate a resistance to the continuous rebound of the spring 43, preventing the thrust exerted on the paper cup by the spring 43 from being too large and thus damaging the paper cup, playing a role in protecting the paper cup. After the paper cup enters the conveying pipe 41, the air pump 414 is started. The airflow generated by the air pump is first shunted and guided through the three-way pipe 413, so that the airflow enters the ventilation ring plate 410. After the ventilation ring plate 410 evenly distributes the airflow, the airflow then enters the conveying pipe 41 in an inclined manner through the inclined air pipe 411. In the conveying pipe 41, the airflow forms an additional thrust on the paper cup, enabling the paper cup to pass through the conveying pipe 41 faster.Meanwhile, due to the acting direction of the air flow and the oblique entry method, it is possible to prevent the paper cup from being stuck inside the conveying pipe 41 due to reasons such as friction and the shape of the paper cup itself, ensuring the smoothness of the paper cup conveying process, and the paper cup falls from the conveying pipe 41 into the second round hole 83.,

[0025] For the second embodiment, please refer to Figures 1 - 8 , the present invention provides an automatic palletizing device for paper cup production: The conveying device 8 includes a sliding plate 81. A deviation prevention mechanism 82 is fixedly connected to the top of the sliding plate 81. Second round holes 83 are opened at both the top and bottom of the sliding plate 81. A rectangular groove 84 is opened on one side of the sliding plate 81. One side of the inner wall of the rectangular groove 84 is fixedly connected to a telescopic spring 85. One end of the telescopic spring 85 away from the inner wall of the rectangular groove 84 is fixedly connected to a baffle 86. A third round hole 87 is opened at the top of the baffle 86. One side of the sliding plate 81 is slidably connected to the inner wall of the chute 5. There are two deviation prevention mechanisms 82, and the two deviation prevention mechanisms 82 are distributed on both sides of the center position of the top of the sliding plate 81. The deviation prevention mechanism 82 includes an arc-shaped column 821. A rectangular hole 822 is opened at the top of the arc-shaped column 821. One side of the inner wall of the rectangular hole 822 is fixedly connected to a connecting rod 823. One end of the connecting rod 823 away from the rectangular hole 822 is fixedly connected to an inclined arc-shaped block 824. One side of the bottom of the inner wall of the rectangular hole 822 is fixedly connected to an electric push rod 825. The movable end of the electric push rod 825 is fixedly connected to an arc-shaped rod 826. The bottom of the arc-shaped column 821 is fixedly connected to the top of the sliding plate 81. There are multiple connecting rods 823, and the multiple connecting rods 823 are distributed on one side of the inner wall of the rectangular hole 822;

[0026] The discharging device 10 includes an arc-shaped elbow 101. One end of the arc-shaped elbow 101 is fixedly connected with an annular plate 102. On the side of the annular plate 102 away from the arc-shaped elbow 101, an L-shaped platform 103 is fixedly connected. An arc-shaped groove 104 is formed at the top of the L-shaped platform 103. A circular groove 105 is formed on one side of the inner wall of the arc-shaped groove 104. A buffer spring 106 is fixedly connected to one side of the inner wall of the arc-shaped groove 104. One end of the buffer spring 106 away from the inner wall of the arc-shaped groove 104 is fixedly connected with a T-shaped rod 107. An inclined sliding platform 108 is fixedly connected to the inner wall of the arc-shaped groove 104. A semi-circular rod 109 is fixedly connected to the top of the inclined sliding platform 108. A rotating sleeve block 1010 is sleeved on and rotatably connected to the semi-circular rod 109. The end of the arc-shaped elbow 101 away from the annular plate 102 is fixedly connected to the bottom of the workbench 1. One end of the T-shaped rod 107 is slidably connected to the inner wall of the circular groove 105. During use, during the falling process of the paper cup, the inclined arc block 824 sets a fixed channel for the paper cup in a circular shape to prevent the paper cup from shifting. The opening of the paper cup faces upward. The electric push rod 825 moves according to the size of the paper cup opening, driving the arc-shaped rod 826 to just fix the bottom paper cup. After the paper cups are stacked, the motor 6 is started to drive the threaded rod 7 to rotate. The threaded rod 7 cooperates with the internal thread of the sliding plate 81, and the sliding plate 81 moves along the inner wall of the chute 5. When the sliding plate 81 is about to move to the top, the baffle 86 contacts the inner wall of the chute 5. The baffle 86 is subjected to pressure, applying pressure to the telescopic spring 85. The telescopic spring 85 is compressed, and the baffle 86 moves inward. When the sliding plate 81 moves to the top, the circular hole two 83 is located directly above the through hole 9. The baffle 86 moves to a position where the circular hole three 87 is exactly directly below the circular hole two 83. The electric push rod 825 contracts, and the arc-shaped rod 826 leaves the cup mouth. The paper cup falls and slides out from the through hole 9, falling into the track formed by the surrounding of the arc-shaped elbow 101 and entering the arc-shaped groove 104. The inner slope of the inclined sliding platform 108 fits the slope of the paper cup wall. When the paper cup slides onto the inclined sliding platform 108, the paper cup is restored to a horizontal and transverse state, and at the same time, the speed of the paper cup is reduced. When the bottom of the paper cup contacts the T-shaped rod 107, due to the gravity and inertia during falling, a certain impact is caused to the T-shaped rod 107. The buffer spring 106 is compressed to buffer the impact force and prevent the bottom of the paper cup from being damaged. The semi-circular rod 109 fixes the paper cup, and the rotating sleeve block 1010 prevents damage to the cup wall due to excessive friction when the paper cup is fixed by the semi-circular rod 109.

[0027] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without making creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.

[0028] When the present invention is in operation, the paper cup falls horizontally into the feeding device 4. The feeding device 4 is activated to push the paper cup and make the paper cup slide into the conveying device 8 through the air flow. After the paper cups are stacked to a certain number in the conveying device 8, the motor 6 is activated to drive the threaded rod 7 to rotate. The threaded rod 7 cooperates with the threads of the conveying device 8, causing the conveying device 8 to move to the top inner wall of the chute 5. When the conveying device 8 reaches this position, the discharge holes inside it open, and the stacked paper cups enter the discharging device 10 through the through holes 9 and slide out from the discharging device 10. The paper cup falls horizontally onto the inner wall of the semi-open tube 42. The power supply inside the electromagnetic chuck 49 is turned on, and the magnetic block 47 is moved towards the electromagnetic chuck 49 by the magnetic force. Since the magnetic block 47 is connected to the round rod 45 and the round rod 45 is connected to the push plate 44, the movement of the magnetic block 47 drives the round rod 45 and the push plate 44 to move synchronously. During the movement of the push plate 44, the spring 43 connected to the push plate is subjected to the force transmitted by the push plate and begins to be compressed. As the magnetic block 47 continues to move, the spring 43 continues to be compressed and stores elastic potential energy. When the magnetic block 47 drives the push plate 44 to move a certain distance, the power supply of the electromagnetic chuck 49 is disconnected. At this time, the magnetic force generated by the electromagnetic chuck quickly disappears, and the pressure exerted on the spring 43 by the push plate 44 also disappears. The spring starts to rebound. During the rebound process, the spring 43 converts the stored elastic potential energy into kinetic energy, driving the push plate 44 to move towards the paper cup and applying a thrust to the paper cup. Under the action of this thrust, the paper cup enters the conveying pipe 41 from the inner wall of the semi-open tube 42. At the same time as the spring 43 rebounds, the elastic cord 46 connected to the push plate 44 or related structures also undergoes elastic deformation. As the spring 43 rebounds, the degree of deformation of the elastic cord 46 gradually increases. When the elastic cord 46 reaches its maximum elastic deformation, it will generate a resistance to the continued rebound of the spring 43, preventing the thrust applied to the paper cup by the spring 43 from being too large and thus damaging the paper cup, playing a role in protecting the paper cup. After the paper cup enters the conveying pipe 41, the air pump 414 is activated. The air flow generated by the air pump is first shunted and guided through the tee pipe 413, causing the air flow to enter the ventilation ring plate 410. After the ventilation ring plate 410 distributes the air flow evenly, the air flow then enters the conveying pipe 41 in an oblique direction through the inclined air pipe 411. In the conveying pipe 41, the air flow forms an additional thrust on the paper cup, enabling the paper cup to pass through the conveying pipe 41 faster. At the same time, due to the acting direction of the air flow and the oblique entry method, it can prevent the paper cup from getting stuck inside the conveying pipe 41 due to friction, the shape of the paper cup itself, etc., ensuring the smoothness of the paper cup conveying process. The paper cup falls from the conveying pipe 41 into the round hole two 83. During the falling process, the inclined arc block 824 sets a fixed channel for the paper cup in a circular shape to prevent the paper cup from shifting. The opening of the paper cup faces upward, and the electric push rod 825 moves according to the size of the paper cup opening, driving the arc-shaped rod 826 to just fix the bottom paper cup. After the paper cups are stacked, the motor 6 is activated to drive the threaded rod 7 to rotate. The threaded rod 7 cooperates with the internal threads of the sliding plate 81, and the sliding plate 81 moves along the inner wall of the chute 5. When the sliding plate 81 is about to move to the top,The baffle 86 contacts the inner wall of the chute 5. The baffle 86 is under pressure, applying pressure to the telescopic spring 85. The telescopic spring 85 is compressed, and the baffle 86 moves inward. When the sliding plate 81 moves to the top, the second round hole 83 is directly above the through hole 9. The baffle 86 moves to a position where the third round hole 87 is exactly directly below the second round hole 83. The electric push rod 825 contracts, the arc-shaped rod 826 leaves the cup mouth, and the paper cup falls, slides out from the through hole 9, and falls into the track formed by the surrounding of the four arc-shaped bent pipes 101 and enters the arc-shaped groove 104. The inner slope of the inclined slide 108 fits the slope of the paper cup wall. When the paper cup slides onto the inclined slide 108, the paper cup is restored to a horizontal and transverse state, and at the same time, the speed of the paper cup is reduced. When the bottom of the paper cup contacts the T-shaped rod 107, due to the gravity and inertia of the fall, a certain impact is caused to the T-shaped rod 107. The buffer spring 106 is compressed to buffer the impact force and prevent the bottom of the paper cup from being damaged. The semi-circular rod 109 fixes the paper cup, and the rotating sleeve block 1010 prevents damage to the cup wall due to excessive friction when the paper cup is fixed by the semi-circular rod 109.
