[0002] In the modern paper tube production process, paper tubes have a very wide range of applications, covering multiple industries such as textile, packaging, and printing. In order to meet the diverse market demands, paper tubes usually need to be cut according to specific uses to obtain finished products with different diameters and thicknesses. After cutting, there may be certain differences in the sizes of paper tubes, which are mainly manifested as different diameters and wall thicknesses. However, paper tubes in the production process are usually processed in batches. Traditional paper tube sorting usually relies on manual operations. Workers need to manually classify and stack paper tubes. This method is not only inefficient and labor-intensive, but also prone to insufficient sorting accuracy due to human errors. In addition, the manual sorting method is difficult to meet the requirements of modern industrial production, especially on production lines that require high precision and high speed.

Detailed Embodiment

[0026] 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 of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-9 , the present invention provides a technical solution for an automatic sorting device applied to paper tube production. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0028] An automatic sorting device applied to paper tube production includes: a base 1, a screening device 3, and an adjustment device 2. The base 1 is used to provide a support foundation for the entire device, ensuring the stability and reliability of each component, and at the same time bearing the weight of the entire sorting system to ensure that the sorting device will not tilt or displace during the working process. The screening device 3 is arranged on the base 1 and is used to preliminarily screen the paper tubes processed by the adjustment device 2 for subsequent sorting operations. The screening device 3 can quickly classify the paper tubes according to their diameters and thicknesses to improve the overall sorting efficiency. The adjustment device 2 is arranged on the top surface of the screening device 3 and is mainly used to preliminarily adjust the directions of the paper tubes so that the disorderly paper tubes can enter the screening device 3 in a consistent direction, reducing jams or sorting errors caused by inconsistent directions in the subsequent sorting process.

[0029] The screening device 3 includes: a fixed disk 301, a rotating ring 302, a retaining ring 3031, a discharge port 3032, an outer ring 3041, a slide 3042, a discharge pipe 305, a top cover 306, a limiting ring 307, a fixed rod 308, a movable rod 309, a pressure rod 310, a receiving rod 311, a shaft rod 312, a dial rod 313, a spring 314 and a power mechanism 315. The fixed disk 301 is fixedly arranged on the outer wall of the top of the base 1 as the supporting basis of the screening device 3 and is fixedly connected to the outer wall of the top of the base 1. The rotating ring 302 is rotatably arranged on the annular outer wall of the fixed disk 301. The rotating ring 302 and the fixed disk 301 are located on the same axis and rotate on the outside of the fixed disk 301. The rotation of the rotating ring 302 is driven by the power mechanism 315. The retaining ring 30 31 is set on the top surface of the rotating ring 302 and is located on the same rotation axis as the rotating ring 302. A discharge port 3032 is provided on the arc-shaped outer wall of the retaining ring 3031 for directional export of the paper tube. The number of the discharge ports 3032 can be adjusted according to actual needs. The top surface of the base 1 and the top surface of the retaining ring 3031 are located on the same plane. The annular space between the base 1 and the retaining ring 3031 is the moving path of the paper tube. The outer ring 3041 is rotatably set on the annular outer wall of the rotating ring 302. A slide groove 3042 is provided on the top surface of the outer ring 3041. The slide groove 3042 is opened along the axial direction of the outer ring 3041 to accommodate the lever 313 and ensure that it can slide along the predetermined path. 305 is set on the arc-shaped outer wall of the outer ring 3041, and is used to receive the sorted paper tubes and guide them to the collection area. The cross-sectional shape of the discharge tube 305 is a rectangular tubular structure, and the design of each discharge tube 305 is optimized according to the diameter of the paper tube to ensure that the paper tube can smoothly enter and be collected. The top cover 306 is set on the outer ring 3041 to protect the internal structure of the sorting device and prevent external dust or debris from entering and affecting the normal operation of the device. The installation method of the top cover 306 is convenient for disassembly to facilitate equipment maintenance and inspection. The limiting ring 307 is set on the top cover 306 and is located on the inner wall of the retaining ring 3031. The number of openings of the limiting ring 307 matches the number of discharge ports 3032. When the retaining ring 3031 and the limiting ring 307 are generated When rotating relative to each other, ensure that at the position where the fixed rod 308 and the movable rod 309 contact each other, the limiting ring 307 is open to ensure that there is no obstruction at the discharge port 3032, and the paper tube can move from the discharge port 3032 out of the area between the base 1 and the retaining ring 3031 to the area outside the retaining ring 3031. The fixed rod 308 is arranged on the top surface of the fixed disk 301. When the rotating ring 302 rotates, the fixed rod 308 and the rotating ring 302 move relative to each other. The movable rod 309 is arranged on the inner wall of the retaining ring 3031 and is located on one side of the discharge port 3032. It is used to cooperate with the fixed rod 308 to guide the movement direction of the paper tube during the sorting process to ensure that it smoothly enters the corresponding discharge port 3032. The pressure rod 310 is arranged on the outer wall of the retaining ring 3031 and is symmetrically distributed with the movable rod 309.The connection between the compression rod 310 and the retaining ring 3031 is elastically hinged. When the compression rod 310 is not subjected to external force, the compression rod 310 abuts against the outer arc wall of the retaining ring 3031. When the paper tube is moved out from the discharge port 3032, the compression rod 310 is lifted up and rotates with the retaining ring 3031. In cooperation with the limiting ring 307, the discharge port 3032 is closed, and the paper tube will move with the retaining ring 3031. The receiving rod 311 is hinged to the inner cavity of the discharge pipe 305 through the shaft rod 312, and is used to receive and guide the paper tube into the discharge pipe 305. At the same time, the receiving rod 311 and the compression rod 310 are staggeredly distributed, and their relative movements will not interfere with each other, ensuring that they can stagger each other during the working process and avoiding mutual influence. This structure enables each rod to maintain an independent working path during movement, thus effectively avoiding possible collisions or jams. The shift lever 313 is slidably arranged in the chute 3042. One end of the reed 314 is arranged on the shaft rod 312, and the other end of the reed 314 is arranged on the shift lever 313. When the shift lever 313 is driven to slide, the receiving rod 311 will be driven to rotate through the reed 314. The power mechanism 315 is arranged on the outer wall of the base 1 and extends to the bottom surface of the outer ring 3041.,

[0030] The outer ring 3041 and the fixed disk 301 remain relatively stationary, and the rotating ring 302 and the fixed disk 301 are in a state of relative rotation. The outer ring 3041 and the fixed disk 301 are fixed at a fixed position and will not move with the rotation of the rotating ring 302, enabling the outer ring 3041 to serve as a stable platform for connecting key components such as the discharge pipe 305. At the same time, the rotating ring 302 can freely rotate relative to the fixed disk 301, and with the drive of the power mechanism 315, the paper tube can be circulated and moved in the sorting device.

[0031] Both the fixed rod 308 and the movable rod 309 are arc-shaped rods, and the bending directions of the fixed rod 308 and the movable rod 309 are the same. The arc design enables the paper tube located between the fixed rod 308 and the movable rod 309 to be pushed to the discharge port 3032 when the distance between the fixed rod 308 and the movable rod 309 gradually decreases. By using their synergistic effect, the paper tube is guided into the correct discharge channel, reducing the resistance when the moving direction of the paper tube changes and avoiding the paper tube from being squeezed and deformed or even damaged.

[0032] The number of discharge pipes 305 is at least two, and the numbers of the receiving rods 311, the shift levers 313 and the reeds 314 match the number of the discharge pipes 305. Each discharge pipe 305 is equipped with corresponding numbers of receiving rods 311, shift levers 313 and reeds 314, ensuring the independence and coordination of each sorting channel. This matching design enables each discharge pipe 305 to be optimized for paper tubes of specific sizes, improving the sorting accuracy and efficiency and meeting the requirements of diversified production.

[0033] At least two lever rods 313 are located at different diameter positions of the outer ring 3041, and are arranged in sequence according to the different distances from the center of the outer ring 3041. They are arranged in order from near to far from the center of the outer ring 3041. This layout enables the device to effectively distinguish and guide paper tubes according to their diameters. A paper tube with a smaller diameter will cause the pressing rod 310 to contact the lever rod 313 closer to the center, while a paper tube with a larger diameter will cause the pressing rod 310 to contact the lever rod 313 farther from the center, and thus be respectively guided into the corresponding discharge pipe 305. This sequential distribution design improves the accuracy of sorting.

[0034] The widths of at least two discharge pipes 305 are different, and are arranged in sequence according to the different widths. The receiving rod 311 in each discharge pipe 305 matches the pipe orifice of the discharge pipe 305.

[0035] The outer arc side of the reed 314 points to the center of the fixed disk 301, ensuring that the reed 314 can produce appropriate elastic deformation when subjected to an external force, providing the necessary reaction force to control the receiving rod 311, so that the receiving rod 311 and the paper tube or the lever rod 313 can make effective contact and interaction during rotation, and guide the paper tube from the outside of the rotating ring 302 into the discharge pipe 305.

[0036] The lever rod 313 is composed of a first-stage lever rod and a second-stage lever rod. The second-stage lever rod is located on the top surface of the first-stage lever rod. The first-stage lever rod is slidably arranged in the chute 3042. The first-stage lever rod and the second-stage lever rod are connected by a flexible connection device, such as an elastomer, a spring or a flexible material, etc. When the pressing rod 310 contacts the second-stage lever rod, it can drive the first-stage lever rod and the second-stage lever rod to move synchronously along the chute 3042. When the first-stage lever rod moves to the maximum limit of the chute 3042, the pressing rod 310 continues to move, and the second-stage lever rod bends. After the pressing rod 310 moves past, under the action of the flexible connection device, it returns to its original position. At the same time, under the action of the reed 314, the first-stage lever rod returns to its original position.

[0037] The power mechanism 315 includes: two fixing plates 3151, a driving motor 3152 and a gear 3153. The two fixing plates 3151 are mirror-image spaced on the outer wall of the base 1. The fixing plate 3151 located above is fixed to the bottom surface of the fixed disk 301 and the bottom surface of the outer ring 3041 to achieve the effect that the rotating ring 302 and the fixed disk 301 and the outer ring 3041 can rotate relatively. The driving motor 3152 is arranged between the two fixing plates 3151. The gear 3153 is installed at the output end of the driving motor 3152. A tooth groove 6154 is opened on the bottom surface of the rotating ring 302, which matches and meshes with the gear 3153.

[0038] The adjusting device 2 includes: a hopper 21, a feed pipe 22, a partition plate 23, an adjusting rope 24, an auxiliary motor 25 and a turntable 26. The partition plate 23 is arranged in the inner cavity of the hopper 21, dividing the hopper 21 into two equal parts. When the messy paper tubes are poured into the hopper 21, several paper tubes will be divided into two parts by the partition plate 23. Two feed pipes 22 are respectively connected to the bottom end of the hopper 21, corresponding to the two regions divided by the partition plate 23. The bottom end of the feed pipe 22 is connected to the top cover 306 and penetrates through the top cover 306. The bottom end of the feed pipe 22 corresponds to the position of the fixed rod 308. When the paper tube falls from the feed pipe 22 onto the fixed disk 301 and rotates with the rotating ring 302, the paper tube will be located between the top rod and the moving rod 309. The number of the adjusting ropes 24 is two. One end of each of the two adjusting ropes 24 is fixedly installed on the inner wall of the hopper 21. The other ends of the two adjusting ropes 24 penetrate through the side wall of the hopper 21 and are slidably connected to the hopper 21. The two adjusting ropes 24 are along the horizontal extension direction of the partition plate 23 and are respectively located on both sides of the partition plate 23. The distance between the two adjusting ropes 24, the partition plate 23 and the hopper 21 is less than the outer diameter of the smallest paper tube. At the same time, the adjusting rope 24 can generate elastic deformation. The auxiliary motor 25 is arranged on the outer wall of the hopper 21. The turntable 26 is arranged at the output end of the auxiliary motor 25. The end parts of the two adjusting ropes 24 located outside the hopper 21 are respectively arranged on the turntable 26, and the connection points of the two adjusting ropes 24 and the turntable 26 are located at the eccentric positions of the turntable 26. The cross-sectional shape of the feed pipe 22 is a rectangular structure, which ensures the direction of the paper tube and at the same time ensures that when the paper tube falls on the fixed disk 301, the axial direction of the paper tube is in a vertical state.

[0039] Working principle: Start the auxiliary motor 25. As the auxiliary motor 25 rotates, along with the rotation of the turntable 26, the two adjusting ropes 24 will be cyclically pulled. The two adjusting ropes 24 will generate displacement and slight vibration. Pour a number of paper tubes with different diameters into the hopper 21 uniformly. When the direction of the paper tube is consistent with the corresponding feed pipe 22, it will directly slide down along the edge of the hopper 21 into the feed pipe 22. When the direction of the paper tube is inconsistent with the corresponding feed pipe 22, it will contact the adjusting rope. By using the acting force of the adjusting rope, and in combination with the distance between the hopper 21 and the adjusting rope, as well as the distance between the adjusting rope and the partition plate 23, which are both smaller than the diameter of the poured paper tube, the paper tube will change its direction and all slide from the hopper 21 into the feed pipe 22, and finally fall onto the surface of the fixed plate 301. Start the power motor to drive the rotating ring 302 to rotate. Along with the rotation of the rotating ring 302, the moving rod 309 will rotate synchronously. When the paper tube comes into contact with both the moving rod 309 and the fixed rod 308, a slight extrusion will be exerted on the paper tube by using the arcs of the ejector rod and the moving rod 309, causing the paper tube to be discharged from the discharge port 3032 and lifting the pressure rod 310. The paper tube rotates synchronously with the rotating ring 302. At the same time, under the action of the limiting ring 307, the discharge port 3032 closes. According to the diameter of the paper tube, the opening angle of the pressure rod 310 is different. When the paper tube moves to the position of the matching discharge pipe 305, the pressure rod 310 contacts the corresponding second-stage lever, driving the corresponding first-stage lever to move along the chute 3042, squeezing the reed 314. At the same time, the corresponding receiving rod 311 rotates. The distal end of the receiving rod 311 away from the shaft rod 312 will move towards the center of the rotating ring 302. The paper tube contacts the receiving pipe. Along with the rotation of the rotating ring 302, and in combination with the arc of the receiving rod 311, the pressure rod 310 squeezes the paper tube, and the paper tube will move towards the corresponding conveying pipe. The end of the conveying pipe is connected to the corresponding storage bag, etc., to complete the sorting. When the rotating ring 302 continues to move, the second-stage lever bends, and the pressure rod 310 separates from the second-stage lever. Under the action of the reed 314, the first-stage lever resets, and the receiving rod 311 resets. The rotating ring 302 continues to rotate to perform the next sorting operation.
