Description

Technical Field

[0001] This utility model relates to the technical field of paper cup stacking devices, and in particular to an automatic stacking device for disposable paper cup production. Background Technology

[0002] In modern disposable paper cup production, efficient and precise automatic stacking devices play a crucial role in improving production efficiency and ensuring product quality. With the continuous growth in market demand for disposable paper cups, manufacturers are increasingly reliant on automated production equipment. Among these, the performance of automatic stacking devices, as a key component of the production process, directly impacts the smoothness and stability of the entire production flow.

[0003] Existing automated stacking devices for disposable paper cup production typically employ relatively conventional mechanical structures. The conveyor belt, as the main component for transporting paper cups, is usually driven by a motor that rotates rollers, using the friction between the rollers and the conveyor belt to transfer the cups. In the stacking stage, simple robotic arms or baffles are generally used to stack the cups according to a fixed program. The underlying technology is based on converting the rotational motion of the motor into the linear motion of the conveyor belt, and the preset actions of the robotic arm to complete the stacking of the paper cups.

[0004] However, existing equipment has certain problems. The position of the conveyor belt is relatively fixed. In actual production, disposable paper cups of different specifications vary in size. The fixed-position conveyor belt is difficult to adjust according to the different sizes of paper cups. This makes it impossible to guarantee the optimal position and stability of paper cups on the conveyor belt when conveying and stacking paper cups of different specifications. This affects the stacking effect and production efficiency of paper cups and greatly limits the applicability of the equipment to different product specifications. Therefore, an automatic stacking device for disposable paper cup production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic stacking device for disposable paper cup production, which aims to improve the problem that the conveyor belt position is relatively fixed and it is difficult to make targeted adjustments according to different paper cup sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic stacking device for disposable paper cup production includes a protective shell. The inner wall of the protective shell is provided with a bottom plate. Multiple conveyor belts are provided on the top of the bottom plate. Multiple pulleys are provided on the inner wall of each conveyor belt. An adjustment component is provided on the outer wall of each pulley. A fixing component is provided on one side of each pulley. A shaped rotating shaft is slidably connected inside each pulley. A connecting plate is fixedly connected to both ends of each shaped rotating shaft. The connecting plate is rotatably connected inside the protective shell.

[0008] The adjustment assembly includes multiple connecting strips, all located on both sides of the pulley. An electric telescopic rod is fixedly connected inside the protective shell, and the output end of the electric telescopic rod is fixedly connected to one side of the base plate. Multiple guide grooves are provided inside the base plate, and the guide grooves at the bottom of the pulleys on adjacent sides are symmetrically distributed. A limit assembly is provided on the outer wall of the pulley.

[0009] As a further description of the above technical solution:

[0010] The limiting assembly includes multiple limiting rings, which are located on both sides of each pulley. A turntable is fixedly connected to both sides of each pulley. A limiting ring is fixedly connected to the outer wall of each turntable. A fixing plate is rotatably connected to the outer wall of each limiting ring.

[0011] As a further description of the above technical solution:

[0012] Each of the fixed plates is fixedly connected to the top of the connecting strip, and multiple protruding strips are fixedly connected to the outer wall of the irregular rotating shaft. The protruding strips are slidably connected inside the turntable and the pulley.

[0013] As a further description of the above technical solution:

[0014] Both sides of the base plate are slidably connected to slide blocks, and the outer wall of the slide blocks is fixedly connected to the inner wall of the protective shell.

[0015] As a further description of the above technical solution:

[0016] A fixing block is fixedly connected to one side of the protective shell, and a motor is fixedly connected inside the fixing block. The output end of the motor is fixedly connected to the outer wall of one of the connecting plates.

[0017] As a further description of the above technical solution:

[0018] A cover plate is fixedly connected to one side of the inner wall of the protective shell, and a second fixing plate is fixedly connected to the other side of the inner wall of the protective shell. Multiple guide plates are fixedly connected to the top of the second fixing plate, and a fixing frame is fixedly connected to the top of the protective shell. A brush shaft is rotatably connected inside the fixing frame.

[0019] As a further description of the above technical solution:

[0020] The fixing assembly includes multiple rubber rollers located on one side of the pulley. Multiple guide grooves are provided inside the base plate. Each rubber roller is fixedly connected to a rotating bar, and connecting frames are fixedly connected to the outer walls of the rotating bars on adjacent sides.

[0021] As a further description of the above technical solution:

[0022] Each of the connecting frames is fixedly connected to a connecting strip 2 at its bottom. The connecting strip 2 is slidably connected to the inner wall of the guide groove 2, and the guide grooves 2 on adjacent sides are symmetrically distributed.

[0023] This utility model has the following beneficial effects:

[0024] In this invention, the guide groove inside the base plate is moved by an electric telescopic rod, thereby adjusting the spacing between the conveyor belts on both sides. This solves the problem that the position of the conveyor belt is relatively fixed and it is difficult to make targeted adjustments according to different paper cup sizes, thus enhancing the applicability of the equipment.

[0025] In this invention, the paper cup is clamped and fixed on both sides by a rubber roller. At the same time, the softness of the rubber roller is used to buffer the slight vibration force transmitted from the equipment to the surface of the paper cup, thereby achieving the effect of fixing the paper cup. This solves the problem that the vibration force of traditional equipment can easily cause the paper cup stack to shift and make it difficult for new paper cups to be accurately fitted onto one end of the paper cup stack, thus enhancing the stability of the paper cups during the stacking process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 An embodiment of this utility model provides an automatic stacking device for disposable paper cup production, including a protective shell 1. A bottom plate 15 is provided on the inner wall of the protective shell 1. Multiple conveyor belts 18 are provided on the top of the bottom plate 15. Multiple pulleys 12 are provided on the inner wall of each conveyor belt 18. An adjustment component is provided on the outer wall of the pulley 12. A fixing component is provided on one side of the pulley 12. A shaped rotating shaft 8 is slidably connected inside each pulley 12. A connecting plate 7 is fixedly connected to both ends of the shaped rotating shaft 8. The connecting plate 7 is rotatably connected inside the protective shell 1.

[0034] The adjustment assembly includes multiple connecting strips 13, all located on both sides of the pulley 12, for supporting and connecting the pulley 12 to ensure its stable operation. An electric telescopic rod 17 is fixedly connected inside the protective housing 1. The output end of the electric telescopic rod 17 is fixedly connected to one side of the base plate 15. The telescopic movement of the electric telescopic rod 17 drives the base plate 15 to move, thereby achieving the spacing adjustment function. Multiple guide grooves 14 are provided inside the base plate 15. The guide grooves 14 on the bottom of adjacent pulleys 12 are symmetrically distributed. The guide grooves 14 guide the sliding of the connecting strips 13, ensuring the smoothness and accuracy of the adjustment process. The outer wall of the pulley 12 is provided with a limiting component, which includes multiple limiting rings 10. The multiple limiting rings 10 are located on both sides of each pulley 12 to limit the axial movement of the pulley 12 and ensure its stability during rotation. A turntable 9 is fixedly connected to both sides of each pulley 12. The turntable 9 is used to transmit power and support the rotation of the pulley 12. A limiting ring 10 is fixedly connected to the outer wall of each turntable 9. The limiting ring 10 is used to further fix the position of the turntable 9 and prevent it from shifting. A fixing plate 11 is rotatably connected to the outer wall of each limiting ring 10. The fixing plate 11 is used to support the limiting ring 10 and ensure its smooth rotation. Each fixed plate 11 is fixedly connected to the top of the connecting strip 13 at its bottom. The fixed plate 11 is linked to the base plate 15 through the connecting strip 13 to ensure the coordination of the overall structure. Multiple protrusions are fixedly connected to the outer wall of the irregular rotating shaft 8. The protrusions are slidably connected inside the turntable 9 and the pulley 12. The protrusions are used to transmit power and ensure the synchronous rotation of the turntable 9 and the pulley 12. Slide seats 16 are slidably connected to both sides of the base plate 15. The slide seats 16 are used to support the base plate 15 and guide its sliding to ensure the smoothness of the adjustment process. The outer wall of the slide seat 16 is fixedly connected to the inner wall of the protective shell 1. The connection between the slide seat 16 and the protective shell 1 enhances the stability of the overall structure. A fixed block 5 is fixedly connected to one side of the protective shell 1. The fixed block 5 is used to fix the motor 6 and provide support for it. The motor 6 is fixedly connected inside the fixed block 5. The motor 6 is used to provide power to drive the entire adjustment assembly. The output end of the motor 6 is fixedly connected to the outer wall of one of the connecting discs 7. The motor 6 drives the irregular rotating shaft 8 to rotate through the connecting disc 7, thereby realizing the adjustment function of the pulley 12.

[0035] Specifically, in the process of adjusting the distance between the two conveyor belts 18, the electric telescopic rod 17 is first started. The output end of the electric telescopic rod 17 drives the base plate 15 to slide inside the two sliding blocks 16. During the movement of the base plate 15, the connecting strip 13 will slide through the guide groove 14, thereby causing the pulley 12 to slide on the outer wall of the irregular rotating shaft 8, thus achieving precise adjustment of the distance between the two pulleys 12. This adjustment process ensures that the distance between the conveyor belts 18 can be flexibly adjusted according to actual needs. Then, the motor 6 is started, and the output end of the motor 6 drives the irregular rotating shaft 8 at one end of one of the connecting discs 7 to rotate. Multiple protrusions on the outer wall of the irregularly shaped rotating shaft 8 will drive the turntable 9 and the pulley 12 to rotate synchronously. While the turntable 9 is rotating, it will drive the limiting ring 10 to slide on the inner wall of the fixed plate 11. The limiting ring 10 limits the position of the turntable 9, thereby ensuring the rotational stability and accuracy of the pulley 12. This realizes the dual function of the pulley 12, which can both rotate and move. This not only improves the applicability of the equipment, but also enhances the flexibility and production efficiency of the equipment, enabling it to better adapt to diverse production needs.

[0036] Reference Figure 2 and Figure 4A cover plate 2 is fixedly connected to one side of the inner wall of the protective shell 1. The cover plate 2 is used to close one side of the protective shell 1 to prevent external dust or debris from entering the equipment and to protect the internal components. A fixing plate 29 is fixedly connected to the other side of the inner wall of the protective shell 1. The fixing plate 29 is used to support and fix the guide plate 20 to ensure its positional stability. Multiple guide plates 20 are fixedly connected to the top of the fixing plate 29. The guide plates 20 are used to guide the sliding of the connecting strip 22 to ensure the accurate movement trajectory of the rubber roller 25. A fixing frame 3 is fixedly connected to the top of the protective shell 1. The fixing frame 3 is used to support and fix the brush shaft 4 to ensure its rotational stability. The brush shaft 4 is rotatably connected inside the fixing frame 3. The brush shaft 4 is used to clean the surface of the paper cups to ensure that the paper cups remain clean during stacking. The fixing assembly includes multiple rubber rollers 25, which are located on one side of the pulley 12. The rubber rollers 25 are used to clamp and fix the paper cups to prevent them from shifting during conveying. Multiple guide grooves 21 are provided inside the plate 15. The guide grooves 21 are used to guide the sliding of the connecting strips 22, ensuring that the rubber roller 25 moves smoothly and accurately. Each rubber roller 25 is fixedly connected to a rotating strip 24, which supports the rubber roller 25 and allows it to rotate around the rotating strip 24 as an axis. Connecting frames 23 are fixedly connected to the outer walls of adjacent rotating strips 24. The connecting frames 23 are used to connect the rotating strips 24 and the connecting strips 22, ensuring the linkage between the rubber roller 25 and the base plate 15. Each connecting frame 23 is fixedly connected to the bottom of the connecting strip 22, which is used to transmit power and ensure the synchronous movement of the rubber roller 25. The connecting strips 22 are slidably connected to the inner wall of the guide grooves 21. The guide grooves 21 are used to limit the movement trajectory of the connecting strips 22, ensuring the positional accuracy of the rubber roller 25. The guide grooves 21 on adjacent sides are symmetrically distributed, which ensures the balance and stability of the rubber roller 25 during movement.

[0037] Specifically, during the process of fixing the paper cups, the movement of the paper cups causes the rubber roller 25 to rotate around the rotating bar 24. The rubber roller 25 clamps and fixes the paper cups by contacting both sides. At the same time, the rubber roller 25, with its own softness, can effectively absorb the slight vibrations transmitted to the surface of the paper cups by the equipment, thereby preventing the paper cup stack from shifting. This not only ensures the stability of the paper cups during the stacking process, but also prevents the situation where new paper cups are difficult to accurately fit onto one end of the paper cup stack, further improving the operating accuracy and efficiency of the equipment. In addition, the rotation of the rubber roller 25 is synchronized with the movement of the paper cups, ensuring the uniform distribution of clamping force and avoiding deformation or damage to the paper cups due to excessive local pressure. The flexibility and elasticity of the rubber roller 25 also reduces frictional damage to the surface of the paper cups during equipment operation, extending the service life of the paper cups, while also reducing the frequency and cost of equipment maintenance. This significantly improves the stability of paper cup stacking and the applicability of the equipment, providing a reliable guarantee for efficient production.

[0038] Working principle: During the adjustment of the distance between the two conveyor belts 18, the electric telescopic rod 17 is activated. The output end of the electric telescopic rod 17 drives the base plate 15 to slide inside the two sliding seats 16. During the movement of the base plate 15, the connecting strip 13 will slide through the guide groove 14, causing the pulley 12 to slide on the outer wall of the irregular rotating shaft 8, thereby adjusting the distance between the pulleys 12 on both sides. Then, the motor 6 is activated. The output end of the motor 6 drives the irregular rotating shaft 8 at one end of one of the connecting discs 7 to rotate. Multiple protrusions on the outer wall of the irregular rotating shaft 8 rotate the turntable 9 and the pulley 12. While rotating, the turntable 9 will drive the limiting ring 10 to slide on the inner wall of the fixed plate 11. The limiting ring 10 limits the position of the turntable 9, thereby achieving the rotation of the pulley 12. This achieves the purpose of both rotating and moving the pulley 12, and achieves the effect of portable adjustment of the distance between the adjacent two conveyor belts 18 according to different sizes of paper cups, enhancing the applicability of the equipment.

[0039] During the process of fixing the paper cups, the movement of the paper cups will cause the rubber roller 25 to rotate around the rotating bar 24 as the axis. The rubber roller 25 is used to clamp and fix the two sides of the paper cups. At the same time, the softness of the rubber roller 25 itself is used to absorb the slight vibrations generated by the equipment to the surface of the paper cups, preventing the paper cups from shifting and making it difficult for new paper cups to be accurately fitted onto one end of the paper cup stack, thus enhancing the stability of the paper cups during the stacking process.
