Detailed Implementation

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Please see Figures 1-9 This invention provides a technical solution for an automatic sorting device applied to paper tube production. Its detailed connection means are well known in the field. The working principle and process are mainly described below. The specific work is as follows.

[0020] An automatic sorting device for paper tube production includes: a base 1, a screening device 3, and an adjustment device 2. The base 1 provides a supporting foundation for the entire device, ensuring the stability and reliability of each component, and also bears the weight of the entire sorting system to ensure that the sorting device does not tilt or shift during operation. The screening device 3 is set on the base 1 and is used to perform preliminary screening of the paper tubes after being processed by the adjustment device 2, so as to facilitate subsequent sorting operations. The screening device 3 can quickly classify the paper tubes according to their diameter and thickness, improving the overall sorting efficiency. The adjustment device 2 is set on the top surface of the screening device 3 and is mainly used to perform preliminary adjustment of the orientation of the paper tubes, so that the disordered paper tubes can enter the screening device 3 with a consistent orientation, reducing jamming or sorting errors caused by inconsistent orientation in subsequent sorting stages.

[0021] 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 chute 3042, a discharge pipe 305, a top cover 306, a limiting ring 307, a fixed rod 308, a moving rod 309, a pressure rod 310, a receiving rod 311, a shaft 312, a lever 313, a spring 314, and a power mechanism 315. The fixed disk 301 is fixedly mounted on the outer wall of the top of the base 1, serving as the supporting foundation for the screening device 3. The rotating ring 302 is rotatably mounted 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 the rotating ring 302 rotates outside the fixed disk 301. The rotation of the rotating ring 302 is driven by the power mechanism 315. The retaining ring 3031... 31 is disposed 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 the directional discharge of the paper tube. The number of 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 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 disposed on the annular outer wall of the rotating ring 302. A sliding groove 3042 is provided on the top surface of the outer ring 3041. The sliding 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 a predetermined path. 305 is located on the arc-shaped outer wall of the outer ring 3041, used to receive the sorted paper tubes and guide them to the collection area. The cross-sectional shape of the discharge pipe 305 is a rectangular tubular structure, and the design of each discharge pipe 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 located 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 easy to disassemble for equipment maintenance and repair. The limiting ring 307 is located 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 interact, the limiting ring 307 will generate a certain number of openings. During relative rotation, the limiting ring 307 is open at the contact position of the fixed rod 308 and the moving rod 309, ensuring that the discharge port 3032 is unobstructed. 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 set on the top surface of the fixed plate 301. When the rotating ring 302 rotates, the fixed rod 308 and the rotating ring 302 move relative to each other. The moving rod 309 is set on the inner wall of the retaining ring 3031 and is located on one side of the discharge port 3032. It is used to guide the movement direction of the paper tube in conjunction with the fixed rod 308 during the sorting process, ensuring that it smoothly enters the corresponding discharge port 3032. The pressure rod 310 is set on the outer wall of the retaining ring 3031 and is symmetrically distributed with the moving rod 309.The connection between the pressure rod 310 and the retaining ring 3031 is elastically hinged. When the pressure rod 310 is not subjected to external force, it abuts against the outer arc wall of the retaining ring 3031. When the paper tube moves out of the discharge port 3032, the pressure rod 310 is lifted up and rotates with the retaining ring 3031. With the cooperation of 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 312. It is used to receive and guide the paper tube into the discharge pipe 305. At the same time, the receiving rod 311 and the pressure rod 310 are staggered and opposite to each other. The movement does not cause interference, ensuring that the components are staggered during operation and avoiding mutual influence. This structure allows each component to maintain an independent working path during movement, effectively preventing potential collisions or jamming. The lever 313 is slidably disposed within the groove 3042. One end of the spring 314 is disposed on the shaft 312, and the other end of the spring 314 is disposed on the lever 313. When the lever 313 is driven to slide, the spring 314 causes the receiving rod 311 to rotate. The power mechanism 315 is disposed on the outer wall of the base 1 and extends to the bottom surface of the outer ring 3041.

[0022] The outer ring 3041 remains relatively stationary with respect to the fixed disk 301, while the rotating ring 302 rotates relative to the fixed disk 301. The outer ring 3041 and the fixed disk 301 are fixed in a fixed position and will not move with the rotation of the rotating ring 302. This allows the outer ring 3041 to serve as a stable platform for connecting key components such as the discharge pipe 305. Meanwhile, the rotating ring 302 can rotate freely relative to the fixed disk 301. Driven by the power mechanism 315, the paper tube can circulate within the sorting device.

[0023] Both the fixed rod 308 and the moving rod 309 are arc-shaped rods, and the bending directions of the fixed rod 308 and the moving rod 309 are the same. The arc design means that when the distance between the fixed rod 308 and the moving rod 309 gradually decreases, the paper tube located between the two will be pushed to the discharge port 3032. By utilizing the synergistic effect of the two, the paper tube is guided into the correct discharge channel, reducing the resistance of the paper tube when changing the direction of movement, and avoiding the paper tube from being squeezed and deformed or even broken.

[0024] There are at least two discharge tubes 305, and the number of receiving rods 311, levers 313, and springs 314 matches the number of discharge tubes 305. Each discharge tube 305 is equipped with a corresponding number of receiving rods 311, levers 313, and springs 314 to ensure the independence and coordination of each sorting channel. This matching design allows each discharge tube 305 to be optimized for paper tubes of a specific size, improving the accuracy and efficiency of sorting and meeting the needs of diversified production.

[0025] At least two levers 313 are located at different diameter positions on the outer ring 3041 and are distributed sequentially according to their distance from the center of the outer ring 3041. This arrangement allows the device to effectively distinguish and guide the paper tubes based on their diameter. Paper tubes with smaller diameters will cause the pressure lever 310 to contact the lever 313 closer to the center, while paper tubes with larger diameters will cause the pressure lever 310 to contact the lever 313 farther from the center, thus being guided into the corresponding discharge tube 305. This sequential distribution design improves the accuracy of sorting.

[0026] At least two discharge pipes 305 have different widths and are distributed in sequence according to their different widths. The receiving rod 311 in each discharge pipe 305 is matched with the opening of the discharge pipe 305.

[0027] The outer arc of the spring 314 points towards the center of the fixed disk 301, ensuring that the spring 314 can generate appropriate elastic deformation when subjected to external force, providing the necessary reaction force to control the receiving rod 311, so that the receiving rod 311 can make effective contact and act with the paper tube or lever 313 during rotation, guiding the paper tube from the outer side of the rotating ring 302 into the discharge tube 305.

[0028] The lever 313 consists of a first lever and a second lever. The second lever is located on the top surface of the first lever. The first lever is slidably disposed in the slide groove 3042. The first lever and the second lever are connected by a flexible connecting device, such as an elastic body, spring, or flexible material. When the pressure rod 310 contacts the second lever, it can drive the first lever and the second lever to move synchronously along the slide groove 3042. When the first lever moves to the maximum limit of the slide groove 3042, the pressure rod 310 continues to move, and the second lever bends. After the pressure rod 310 moves past, it returns to its original position under the action of the flexible connecting device. At the same time, under the action of the spring 314, the first lever returns to its original position.

[0029] The power mechanism 315 includes two fixed plates 3151, a drive motor 3152, and a gear 3153. The two fixed plates 3151 are mirror-separated on the outer wall of the base 1. The upper fixed plate 3151 is fixed to the bottom surface of the fixed disk 301 and the bottom surface of the outer ring 3041, so that the rotating ring 302 can rotate relative to the fixed disk 301 and the outer ring 3041. The drive motor 3152 is disposed between the two fixed plates 3151. The gear 3153 is installed at the output end of the drive motor 3152. The bottom surface of the rotating ring 302 has a toothed groove 6154, which matches and meshes with the gear 3153.

[0030] The adjusting device 2 includes: a hopper 21, a feed pipe 22, a partition plate 23, adjusting ropes 24, an auxiliary motor 25, and a turntable 26. The partition plate 23 is located inside the hopper 21, dividing the hopper 21 into two equal parts. When 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 areas divided by the partition plate 23. The bottom end of the feed pipe 22 is connected to the top cover 306 and passes 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 tubes fall from the feed pipes 22 onto the fixed plate 301, with the rotation of the rotating ring 302, the paper tubes will be located between the top rod and the moving rod 309. There are two adjusting ropes 24, one end of which is fixedly installed on the inner wall of the hopper 21. The other ends of the two adjusting ropes 24 pass through the side wall of the hopper 21 and are slidably connected to the hopper 21. The two adjusting ropes 24 extend horizontally along the partition plate 23 and are 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 minimum paper tube. The adjusting ropes 24 can undergo elastic deformation. The auxiliary motor 25 is set on the outer wall of the hopper 21. The turntable 26 is set at the output end of the auxiliary motor 25. The ends of the two adjusting ropes 24 located outside the hopper 21 are respectively set on the turntable 26, and the connection point between the two adjusting ropes 24 and the turntable 26 is located at the eccentricity of the turntable 26. The cross-sectional shape of the feed pipe 22 is rectangular to ensure the direction of the paper tube and to ensure that the axial direction of the paper tube is vertical when the paper tube falls on the fixed plate 301.

[0031] Working principle: The auxiliary motor 25 is started, and as it rotates with the turntable 26, it cyclically pulls on the two adjusting ropes 24. This causes the adjusting ropes 24 to shift and vibrate slightly, drawing paper tubes of different diameters into the hopper 21. When the paper tube's direction aligns with the corresponding feed pipe 22, it slides directly down the edge of the hopper 21 into the feed pipe 22. When the paper tube's direction does not align with the corresponding feed pipe 22, it comes into contact with the adjusting ropes. The force of the adjusting ropes, combined with the movement of the hopper 21, causes the paper tube to... The spacing between the adjusting ropes and the spacing between the adjusting ropes and the partition plate 23 are both smaller than the diameter of the paper tube, causing the paper tube to change direction and slide from the hopper 21 into the feed pipe 22, eventually falling onto the surface of the fixed plate 301. The power motor is then started, driving the rotating ring 302 to rotate. As the rotating ring 302 rotates, the moving rod 309 rotates synchronously. When the paper tube comes into contact with both the moving rod 309 and the fixed rod 308, the curvature of the push rod and the moving rod 309 applies slight pressure to the paper tube, causing it to exit through the discharge port 303. 2. Discharge: The pressure rod 310 is lifted, and the paper tube rotates synchronously with the rotating ring 302. Simultaneously, under the action of the limiting ring 307, the discharge port 3032 closes. Depending on the diameter of the paper tube, the opening angle of the pressure rod 310 varies. When the paper tube moves to the matching discharge pipe 305 position, the pressure rod 310 contacts the corresponding second-stage lever, driving the corresponding first-stage lever to move along the slide groove 3042, squeezing the spring 314. Simultaneously, the corresponding receiving rod 311 rotates, and the end of the receiving rod 311 furthest from the shaft 312 will... As the rotating ring 302 moves in the direction of its center, the paper tube comes into contact with the receiving tube. With the rotation of the rotating ring 302, in conjunction with the curvature of the receiving rod 311, the pressure rod 310 squeezes the paper tube, causing it to move towards the corresponding conveying tube. The end of the conveying tube is connected to the corresponding storage bag, etc., completing the sorting. When the rotating ring 302 continues to move, the second section lever bends, and the pressure rod 310 separates from the second section lever. Under the action of the spring 314, the first section lever resets, the receiving rod 311 resets, and the rotating ring 302 continues to rotate for the next sorting operation.
