Description

Technical Field

[0001] This invention relates to the field of plastic belt conveying technology, and more specifically to a blown plastic belt conveyor for disposable plastic cups. Background Art

[0002] Disposable plastic cups are widely used in catering, retail, and other scenarios due to their convenience. Their processing efficiency and product quality directly affect the production capacity and market competitiveness of manufacturers. Currently, the main processing flow for disposable plastic cups is as follows: the material strip is usually fed into the blow molding machine from one side. After passing between the upper and lower molds, the material strip moves upwards at an angle to the top of the blow molding machine, and finally, the waste strip is wound up by a winding machine; the disposable plastic cups produced by the blow molding machine are blown out onto the hopper. However, the existing processing flow has the following drawbacks in practical applications: 1. Dust and other impurities easily adhere to the outer wall of the material strip used for blow molding during transfer and conveying. The current processing system lacks a cleaning process for the material strip. When the material strip with impurities enters the blow molding process, the impurities are easily embedded in the cup body molding structure, resulting in surface defects and insufficient structural strength of disposable plastic cups, which seriously affects the product molding quality. 2. The formed cups often require manual stacking, which is not only time-consuming, but also prone to microbial contamination due to individual contact with each cup. Although some existing technologies are designed with multiple sets of circular conveyor belts to receive the blown cups for rapid stacking, the cups often fall onto the conveyor belts in a disordered horizontal and vertical arrangement, requiring workers to clean and adjust them frequently, making the operation cumbersome. At the same time, the blow molding machine needs to be equipped with a material belt input system on one side and a circular conveyor belt on the other side, which greatly increases the length of the entire processing line and the floor space required, which is not conducive to the optimal use of space in the production workshop. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a blown plastic conveyor belt device for disposable plastic cups, which solves the problems mentioned in the background art.

[0014] This invention provides a blown plastic conveyor belt device for disposable plastic cups. Compared with the prior art, it has the following advantages: 1. The first, second, and third guide components of the material belt are arranged above the conveyor base of the cup body, and the material belt conveying direction is opposite to the cup body conveying direction, so that the cup body export and material belt processing are carried out simultaneously, reducing process intervals, improving overall production efficiency, and also reducing the overall floor space. 2. The first guiding component can output the material belt horizontally at a low position, which can achieve the following effects: The first guiding component can stretch the material belt up and down to ensure the guiding tension of the material belt; The horizontal part of the material belt is placed above the stacking area of ​​the circular conveyor belt, which can vertically restrain the floating stacked cups and prevent the cups from floating too much and falling off; When a certain amount of cups are stacked, one end of the first guiding component can be lowered to stop the cups, which can directly intercept the subsequent tilted cups without the need for an additional stop structure. 3. The design of the second guide assembly can achieve the following effects: The brush cleaning roller group (double-sided cleaning of material belt impurities) of the second guide assembly works in conjunction with the guide dust suction roller group (sucking in and cleaning impurities) to thoroughly remove impurities from the surface of the material belt and prevent impurities from entering the blow molding machine and affecting the quality of the cup; the brush cleaning roller group also reverses the cup body, allowing only cup bodies with qualified posture to pass through, realizing the posture adjustment of the cup body, which is convenient for subsequent stacking of cup bodies; 4. The cups can be output in rows using a circular conveyor belt. Combined with brush cleaning rollers and guide plates, the cups are adjusted to an inclined state so that the stacking assembly can intermittently push the cups, enabling the cups to be stacked one by one without manual stacking. Workers only need to adjust the packing, which effectively improves the processing efficiency of the cups. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Combination Figure 1 - Figure 10 As shown, the disposable plastic cup blow molding belt conveyor device provided by the present invention includes: The feeding roller 100 has a material belt 110 that is intermittently released wrapped around its outer wall; The first guiding component 200 is located at the output end of the feeding component. The feeding height of the first guiding component 200 is lower than the height of the feeding roller 100. The first guiding component is used to horizontally guide the material belt 110 at a low position. The second guiding component 300 is located at the output end of the first guiding component 200. It includes a guiding dust suction roller group 310 and a brush cleaning roller group 320 arranged sequentially along the guiding direction of the material belt 110. The brush cleaning roller group 320 is used to clean impurities on the outer wall of the material belt 110 on both sides, and the guiding dust suction roller group 310 is used to guide the material belt 110 and suck up the cleaned impurities. The third guide assembly 400 is located at the output end of the second guide assembly 300 and is used to guide the material belt 110 to the blow molding machine 800 to make the cup body 900 and to wind up the waste material belt. A plastic cup delivery assembly includes a conveyor base 500 located at the bottom of a first guide assembly 200 and a second guide assembly 300. Multiple sets of annular conveyor belts 510 are longitudinally spaced inside the conveyor base 500. One end of each annular conveyor belt 510 extends to the side of the blow molding machine to receive the blown cup 900. An operating plate 520 is installed at the other end of each annular conveyor belt 510. The conveying direction of the annular conveyor belt 510 is opposite to the conveying direction of the material belt 110. An upper stacking assembly 600 is installed at the junction of the operating plate 520 and the annular conveyor belt 510. The upper stacking assembly 600 is used to intermittently push the cups 900 at the end of the annular conveyor belt 510, so that the input cups 900 are stacked one by one. The circular conveyor belt 510 consists of a feeding area 511, an adjustment area 512, and a stacking area 513 along the conveying direction. The adjustment area 512 is located at the bottom of the brush cleaning roller group 320. The brush cleaning roller group 320 is used to reverse the cup 900 of the adjustment area 512 so that the cup 900 with the correct posture can pass through. The stacking area 513 is located at the bottom of the first guiding assembly 200. Multiple sets of guide plates 540 are provided in the stacking area 513 between adjacent annular conveyor belts 510. The guide plates 540 are used to adjust the vertical cups 900 to an inclined state with their openings facing the output end. A stacking constraint channel 530 is formed between the stacking area 513 and the horizontal material belt guided by the first guiding assembly 200. The first guiding assembly 200 is used to constrain the upward floating height of the stacked cups 900 and to stop the cups 900 input to the adjustment area at regular intervals.

[0019] In the above scheme: 1. The first guiding component 200, the second guiding component 300, and the third guiding component 400 of the conveyor belt 110 are arranged above the conveyor base 500 of the cup body 900, and the guiding direction of the conveyor belt 110 is opposite to the guiding direction of the cup body 900, so that the cup body 900 is discharged and the processing of the conveyor belt 110 are carried out simultaneously, reducing the process interval, improving the overall production efficiency, and also reducing the overall floor space. 2. The first guide assembly 200 can output the material belt 110 at a low horizontal position, which can achieve the following effects: 2.1 The first conveying assembly can stretch the material belt 110 vertically to ensure the conveying tension of the material belt 110: 2.2 The horizontal part of the material belt is placed above the stacking area 513 of the circular conveyor belt 510, which can vertically restrain the floating stacked cups 900 and prevent the cups 900 from floating too much and detaching. 2.3 When a certain amount of cups 900 are stacked, one end of the first guide component 200 can be lowered to stop the cups 900, which can directly intercept the subsequent tilted cups 900 without the need for an additional stop structure. 3. The design of the second guide component 300 can achieve the following effects: 3.1 The brush cleaning roller group 320 (double-sided cleaning of impurities on the material strip 110) of the second guiding component 300 works in conjunction with the guiding dust suction roller group 310 (sucking in and cleaning impurities) to thoroughly remove impurities from the surface of the material strip 110 and prevent impurities from entering the blow molding machine 800 and affecting the quality of the cup body 900. 3.2 The brush cleaning roller group 320 also reverses the direction of the cup body 900, allowing only cup bodies 900 with qualified postures to pass through, thereby adjusting the posture of the cup body 900 and facilitating the subsequent stacking of the cup bodies 900. 4. The circular conveyor belt 510 can output the cups 900 in rows. Combined with the brush cleaning roller group 320 and the guide plate 540, the cups 900 are adjusted to an inclined state so that the stacking assembly 600 can intermittently stack the cups 900, realizing the stacking of the cups 900 one by one. No manual stacking is required. Workers only need to adjust the box, which effectively improves the processing efficiency of the cups 900.

[0020] In this embodiment, the first guiding assembly 200 includes a first guiding roller 210, a second guiding roller 220, a third guiding roller 230, and a fourth guiding roller 240 arranged sequentially along the conveying direction. The height of the first guiding roller 210 is greater than the height of the discharge roller 100. A first driving rod 211 for driving the first guiding roller 210 to rise and fall is installed at the bottom of the first guiding roller 210. The height of the second guiding roller 220 is lower than that of the first guiding roller 210. A third guiding roller 240 is provided on one side of the second guiding roller 220. The roller 230 has two sets of vertically arranged third guide rollers 230. The material belt 110 between the second guide roller 220 and the third guide roller 230 is a horizontal material belt. A fourth guide roller 240 is provided on the output side of the third guide roller 230. A second drive rod 241 for driving the third guide roller 230 to rise and fall is installed on the top of the fourth guide roller 240. The material belt 110 passes sequentially through the top surface of the first guide roller 210, the bottom surface of the second guide roller 220, between the two sets of third guide rollers 230, and the bottom surface of the fourth guide roller 240. When the fourth guide roller 240 descends, the first guide roller 210 descends synchronously, so that the bottom of the fourth guide roller 240 is placed at the entrance end of the stacking constraint channel 530 to stop the cup body 900 from entering. When the fourth guide roller 240 rises, the first guide roller 210 rises synchronously, so that the fourth guide roller 240 is positioned above the third guide roller 230.

[0021] In the above scheme: 1. The first guide roller 210 and the fourth guide roller 240 can be raised and lowered to adjust the tension of the material belt 110, so that the material belt 110 is in a taut state and the flatness of the horizontal section of the material belt 110 is ensured. 2. When the cups 900 are stacked to a specified quantity, the fourth guide roller 240 and the first guide roller 210 descend synchronously. The material strip 110 at the bottom of the fourth guide roller 240 is placed at the entrance of the stacking constraint channel 530, which can directly intercept the subsequent tilted cups 900 without the need for an additional stop structure. It works in coordination with the manual removal of the stacked cups 900 to ensure the continuity of the operation.

[0022] In this embodiment, the height of the guide suction roller group 310 is lower than that of the feeding roller 100 and higher than that of the fourth guide roller 240. The guide suction roller group 310 includes a first positioning frame 311. Two sets of fifth guide rollers 312 are vertically symmetrically arranged inside the first positioning frame 311. The material belt 110 passes between the two sets of fifth guide rollers 312. The fifth guide roller 312 has a hollow structure and a suction port 313 is opened on the side facing the brush cleaning roller group 320. The sides of the two sets of fifth guide rollers 312 are connected in parallel with a suction fan 314.

[0023] In the above scheme: the two sets of fifth guide rollers 312 of the guide suction roller group 310 are hollow structures, and the suction port 313 is opened on the side. With the parallel suction fan 314, negative pressure can be generated immediately after cleaning impurities, so that the impurities cleaned by the brush are sucked into the interior of the fifth guide roller 312 through the suction port 313 and discharged, avoiding the scattering of impurities and causing secondary pollution.

[0024] In this embodiment, the brush cleaning roller assembly 320 includes a second positioning frame 321. An upper brush roller 322 is rotatably mounted on the upper part of the second positioning frame 321, and a lower brush roller 323 is rotatably mounted on the lower part of the second positioning frame 321. The material belt 110 passes horizontally between the upper brush roller 322 and the lower brush roller 323. The top of the lower brush roller 323 cleans the bottom surface of the material belt 110, and the bottom of the lower brush roller 323 reverses the direction of the cup 900 on the annular conveyor belt 510, so that only the cup 900 that falls vertically between the two sets of annular conveyor belts 510 passes through.

[0025] In the above scheme: 1. The upper brush roller 322 and the lower brush roller 323 of the brush cleaning roller group 320 are respectively attached to the top and bottom surfaces of the material strip 110 to simultaneously clean impurities on both sides of the material strip 110, making the cleaning more thorough and avoiding the impact of impurity residue on the blow molding quality of the cup body 900.

[0026] 2. The bottom of the lower brush roller 323 extends above the circular conveyor belt 510 and reverses the cup 900 in the adjustment area 512, allowing only the cup 900 that is vertically stuck between the two sets of circular conveyor belts 510 to pass through, thereby realizing automatic screening of the posture of the cup 900, reducing subsequent adjustment processes, and improving the posture qualification rate before stacking.

[0027] In this embodiment, the third guiding assembly 400 includes a sixth guiding roller 410, a seventh guiding roller 420, and a take-up roller 430 arranged sequentially along the conveying direction. The seventh guiding roller 420 and the take-up roller 430 are located on both sides of the blow molding machine 800. The material strip 110 passes through the bottom surface of the sixth guiding roller 410, the top surface of the seventh guiding roller 420, and the blow molding machine 800. The end of the material strip 110 is wrapped around the take-up roller 430.

[0028] In the above scheme: the sixth guide roller 410 and the seventh guide roller 420 of the third guide assembly 400 are arranged sequentially along the conveying direction of the material strip 110. The material strip 110 is conveyed along the path of "bottom surface of the sixth guide roller 410 → top surface of the seventh guide roller 420 → blow molding machine 800". Through the constraint of multiple sets of guide rollers, the conveying path of the material strip 110 is ensured to be stable and deviation is avoided, so that the circular material pieces cut by the blow molding machine 800 are accurately positioned, and the forming accuracy of the cup body 900 is improved. The cut waste strip is directly wound onto the take-up roller 430, and the waste strip is orderly wound up by the active rotation of the take-up roller 430.

[0029] During cleaning, the brush cleaning roller group 320 may generate static electricity on the membrane. To solve this problem, in this embodiment, a static electricity elimination group 330 is installed between the sixth guide roller 410 and the brush cleaning roller group 320. The static electricity elimination group 330 includes a third positioning frame 331. The plasma fan box 332 is vertically symmetrically arranged inside the third positioning frame 331. The material belt 110 passes between the two plasma fan boxes 332. The bottom surface of the lower plasma fan box 332 is provided with an assembly plate 333. A vertical actuation component 700 is installed on the bottom surface of the assembly plate 333. The vertical actuation component 700 is used to adjust the posture of the cup 900 of the feeding area 511.

[0030] In the above scheme, the two sets of plasma fan boxes 332 of the static eliminator group 330 are symmetrically distributed on both sides of the material strip 110. They can output plasma air to neutralize the static electricity on the surface of the material strip 110, prevent the material strip 110 from adsorbing environmental impurities, ensure that the material strip 110 remains clean until the blow molding process, and improve the molding quality of the cup body 900. At the same time, the static eliminator group 330 can also serve as the mounting base for the vertical toggle assembly 700.

[0031] Relying solely on the lower brush roller 323 will result in a significant amount of defective cups 900 remaining at the feeding area 511. To improve the adjustment dimension of the cups 900 and accelerate their output speed, in this embodiment, the vertical actuation assembly 700 includes an actuating element 710, a horizontal linkage rod 740, a vertical linkage rod 750, and a base plate 720. The side wall of the conveying base 500 is provided with the base plate 720. A first support rod 721 is fixedly mounted on the surface of the base plate 720, and a second support rod 722 is rotatably mounted on the surface of the base plate 720. A first rotating plate 730 is fixedly mounted at the top of the second support rod 722, and a first drive column 731 is provided on the top surface of the first rotating plate 730. A bevel tooth rod 324 is provided at the outer end of the lower brush roller 323. The outer wall of the second support rod 722 is provided with a mating bevel tooth 732 that meshes with the bevel tooth rod 324; the middle part of the horizontal linkage rod 740 is rotatably mounted on the top of the first support rod 721; the two ends of the horizontal linkage rod 740 are provided with a first sliding groove 741 and a second sliding groove 742, and the first drive column 731 vertically penetrates the second sliding groove 742; the longitudinal linkage rod 750 is longitudinally slidably mounted on the bottom surface of the assembly plate 333, the inner wall of the longitudinal linkage rod 750 is provided with a rack 751, the top surface of the outer end of the longitudinal linkage rod 750 is provided with a second drive column 752, the second drive column 752 vertically penetrates the first sliding groove 741, and the bottom surface of the assembly plate 333 is rotatably mounted with multiple sets of actuating elements 710, and the rack 751 is meshed with the multiple sets of actuating elements 710.

[0032] In the above scheme: 1. The vertical actuation component 700, through the linkage structure of the horizontal linkage rod 740 and the vertical linkage rod 750, converts the rotation of the first rotating plate 730 into the longitudinal sliding of the vertical linkage rod 750. The rack 751 of the vertical linkage rod 750 drives multiple sets of actuating components 710 to move synchronously, so as to achieve uniform actuation of the cup body 900 in the feeding area 511 and avoid the problem of local adjustment not being in place.

[0033] 2. The driving force of the horizontal linkage rod 740 comes from the bevel tooth rod 324 of the lower brush roller 323, which can ensure that the tossing action matches the conveying speed of the cup body 900, avoid adjustment lag or excessive tossing, improve the posture adjustment accuracy, and eliminate the need for a separate drive structure.

[0034] In this embodiment, the actuating component 710 includes a rotating column 711, a fixing plate 712, and vertical brush bristles 713. Multiple sets of rotating columns 711 are arranged longitudinally at intervals. All sets of rotating columns 711 are rotatably mounted on the bottom surface of the mounting plate 333. Each set of rotating columns 711 has a first gear 714 on its outer wall. The rack 751 is meshed with multiple sets of first gears 714. Each set of rotating columns 711 has a fixing plate 712 vertically arranged at its bottom end. Vertical brush bristles 713 are evenly embedded in the bottom surface of the fixing plate 712.

[0035] In the above solution: the bottom of the fixing plate 712 of the actuating component 710 is embedded with vertical brush bristles 713 (flexible material). When the cup body 900 is actuated, the vertical brush bristles 713 make flexible contact with the cup body 900, avoiding surface damage caused by rigid scratching and ensuring the appearance quality of the cup body 900. The rotating column 711 drives the fixing plate 712 and the vertical brush bristles 713 to make a circular motion. The vertical brush bristles 713 can stir the cup body 900 from multiple directions, making all-round adjustments to the tilted or horizontally placed cup body 900, ensuring that the cup body 900 is adjusted to a near-vertical state, and improving the posture qualification rate.

[0036] To ensure that the guide plate 540 can smoothly guide the cup body 900, in this embodiment, the guide plate 540 includes a horizontal support plate 541, a fixing rod 542 is provided on the bottom surface of the horizontal support plate 541, an arc-shaped guide plate 543 is provided at the input end of the horizontal support plate 541, and side constraint plates 544 are symmetrically provided on the surface of the horizontal support plate 541. The height of the horizontal support plate 541 is lower than the top height of the annular conveyor belt 510.

[0037] In the above scheme: the arc-shaped guide plate 543 of the guide plate 540 can abut against the bottom of the vertical cup 900, guiding the cup 900 to rise and gradually turn to an inclined state, avoiding tipping caused by direct collision; the horizontal support plate 541 supports the bottom of the inclined cup 900, ensuring a smooth transition process. The side constraint plates 544 of the guide plate 540 are symmetrically distributed on both sides of the horizontal support plate 541, providing lateral constraint on the inclined cup 900, preventing the cup 900 from shifting, and ensuring that the cup 900 accurately enters the stacking constraint channel 530 (in conjunction with the horizontal material belt of the first guide assembly 200), providing precise positioning for subsequent automatic stacking.

[0038] To achieve stable stacking of the cups 900, in this embodiment, the upper stacking assembly 600 includes a drive shaft 610, a horizontal guide rail 670, and an abutment plate 651. The drive shaft 610 is rotatably mounted inside the conveying base 500. The outer wall of the drive shaft 610 is provided with multiple sets of second gears 620. A vertical rod 660 is slidably mounted on the top of the horizontal guide rail 670. A sliding sleeve 650 is vertically fitted on the top outer wall of the vertical rod 660. The top of the sliding sleeve 650 is provided with an abutment plate 651. A connecting column 642 is provided on the side wall of the sliding sleeve 650. The connecting column 642 is fixed to the side wall of the second rotating plate 640. The second rotating plate 640 is rotatably mounted inside the support plate 630. A third gear 641 is provided at the rotating shaft end of the second rotating plate 640. The third gear 641 meshes with the second gear 620. The support plate 630 is fixedly installed inside the conveying base 500 to provide support.

[0039] In the above scheme: 1. The drive shaft 610 of the upper stacking assembly 600 drives the second gear 620 to rotate, and drives the second rotating plate 640 to rotate through the third gear 641. The second rotating plate 640 drives the sliding sleeve 650 to slide vertically along the vertical rod 660 through the connecting column 642, so that the contacting convex plate 651 reciprocates to extend outward from the annular conveyor belt 510, intermittently lifting the cup body 900 (temporarily holding the cup body 900). The subsequent cup body 900 can be accurately fitted onto the tail end of the previous temporary cup body 900, realizing automatic stacking without manual intervention.

[0040] 2. The vertical sliding range (top height) and lateral movement (resistance force) of the contact plate 651 are precisely controlled by gear transmission to avoid excessive force from damaging the cup body 900. At the same time, the rotation frequency of the drive shaft 610 is matched with the conveying speed of the ring conveyor belt 510 to ensure that the stacking rhythm is coordinated with the conveying rhythm of the cup body 900, thereby improving the compactness and efficiency of stacking.

[0041] Working principle and usage process of this invention: S1, Belt 110 Conveyor: The feeding roller 100 operates intermittently and actively, releasing the material belt 110. When the material belt 110 passes between the upper brush roller 322 and the lower brush roller 323, the upper brush roller 322 and the lower brush roller 323, which rotate in opposite directions, work together to clean the residual impurities on both sides of the material belt 110. The brushed-off impurities will move towards the fifth guide roller 312. The dust extraction fan 314 generates negative pressure at the dust extraction port 313, causing the impurities to be output through the interior of the fifth guide roller 312. Then the material strip 110 will pass through two sets of plasma fan boxes 332. The plasma fan box 332 can output plasma air to eliminate the static electricity on both sides of the material strip 110. Then the material strip 110 is output to the blow molding machine 800. Multiple circular pieces are cut downwards on the material strip 110. The circular pieces are heated and blown by the upper and lower molds in the blow molding machine 800 to produce disposable plastic cups. The cut waste strip is wound up on the take-up roller 430. When the upper and lower molds of the blow molding machine 800 are opened, the discharge fan 810 blows out high-pressure gas, causing the cup body 900 to be blown out and then discharged through the discharge ramp 820. S2, Cup body 900 output: The falling cup 900 lands irregularly on the annular conveyor belt 510. As the cup 900 passes each set of actuating components 710, the lower brush roller 323 rotates, driving the bevel gear 324 to rotate. The bevel gear 324 drives the mating bevel gear 732 to rotate, which in turn drives the second support rod 722 and the first rotating plate 730 to rotate. The first rotating plate 730 drives the first drive column 731 to rotate. The first drive column 731 moves within the second slide groove 742 and drives the horizontal linkage rod 740 to rotate around the hinge point of the first support rod 721. The first slide groove 742 of the horizontal linkage rod 740... 41. The second drive column 752 moves longitudinally against the second drive column 752, which drives the longitudinal linkage rod 750 to move longitudinally. The longitudinal linkage rod 750 drives each set of first gears 714 to rotate through the rack 751. The first gears 714 drive the rotating column 711 to rotate, which in turn drives the fixed plate 712 and the vertical brush 713 at the bottom to make a circular motion. The vertical brush 713 can agitate the cup 900, so that the cup 900 that is horizontally and vertically connected on the circular conveyor belt 510 is horizontally adjusted, so that most of the cups 900 are vertically stuck between the two circular conveyor belts 510. After one attitude adjustment, the cup body 900 passes the bottom of the lower brush roller 323. The lower brush roller 323 vertically adjusts the attitude of the cup body 900 so that only the cup body 900 stuck between the two circular conveyor belts 510 is output. After the second adjustment, the cup body 900 continues to be output along the circular conveyor belt 510. The bottom of the vertically arranged cup body 900 is first abutted by the arc-shaped guide plate 543, which makes the cup body 900 rise to an inclined near-horizontal state. The opening of the cup body 900 faces the upper stacking assembly 600. The inclined cup body 900 is continued to be transported by the circular conveyor belt 510. The horizontal material belt above and the circular conveyor belt 510 form a stacking constraint channel 530. Then the cup body 900 enters the stacking constraint channel 530, and the side constraint plate 544 constrains and guides the cup body 900. The drive shaft 610 drives the second gear 620 to rotate, which in turn drives the third gear to rotate. The third gear 641 drives the second rotating plate 640 and the connecting column 642 to rotate. The connecting column 642 drives the sliding sleeve 650 to move. The sliding sleeve 650 slides vertically along the vertical rod 660 and also drives the vertical rod 660 to move laterally along the horizontal guide rail 670, so that the contact plate 651 reciprocates and extends outward on the annular conveyor belt 510. The contact plate 651 contacts the cup body 900, so that the cup body 900 is lifted and temporarily held. The newly input cup body 900 will be fitted onto the tail end of the previously lifted and temporarily held cup body 900. The horizontal material belt can vertically stop the stacked cup bodies 900 to prevent the cup bodies 900 from being lifted too much and falling off. The first drive rod 211 and the second drive rod 241 are started at regular intervals. When started, a certain number of cups 900 have been stacked, and it is necessary to stop the subsequent cups 900 from entering the stacking constraint channel 530. The second drive rod 241 drives the fourth guide roller 240 to descend, and the first drive rod 211 drives the first guide roller 210 to descend. The fourth guide roller 240 drives the bottom material belt 110 to approach the circular conveyor belt 510 and place it in front of the entrance end of the stacking constraint channel 530. In this way, the fourth guide roller 240 and the bottom material belt 110 can stop the input cups 900 in an inclined state. At this time, the worker can quickly remove each stacked cup 900 to the operation plate 520 for further sorting and packing.
