Description
Technical Field
[0001] This utility model relates to the field of paper tube production technology, specifically to a seamless paper tube production equipment. Background Technology
[0002] Paper tubes: Tubular objects made from paper. Most paper tubes are spiral paper tubes and seamless paper tubes. Seamless paper tubes are used to wind brittle and valuable threads or strips. When the product is wound on the paper tube, the surface of the product is flat with little bumps and a low chance of breakage. In the production process of seamless paper tubes, paper is impregnated with resin. After the resin solidifies, it is polished to form a cylindrical paper tube.
[0003] Grinding is a step that affects the quality of paper tube production. During the grinding process, the paper tube is held by a clamping component. The existing clamping components have relatively fixed dimensions. When grinding paper tubes of different sizes, different clamping components need to be replaced, which affects the grinding efficiency of the paper tube.
[0004] Therefore, it is necessary to invent a seamless paper tube production equipment to solve the above problems. Utility Model Content

[0014] Optionally, the abutment plate is fixedly connected to the left end of the support rod, and the plug block is fixedly connected to the right end of the support rod.
[0015] By adopting the above technical solution, the abutment plate limits the leftmost first transmission rod, so that when the first transmission rod rotates to its maximum angle, it is perpendicular to the support rod.
[0016] Optionally, the right end of the movable sleeve is engaged inside the snap-fit groove.
[0017] By adopting the above technical solution, the piston rod in the cylinder slides left and right through the snap-fit block during the extension and retraction process.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0032] This utility model provides, for example Figures 1 to 4The seamless paper tube production equipment shown includes a mounting base 1. Two sets of cylinders 11 are fixedly mounted on the right side surface of the mounting base 1. A snap-fit block 12 is fixedly connected to the left end of the piston rod in the cylinder 11. A snap-fit groove 13 is opened at the close end of the two sets of snap-fit blocks 12. A clamping assembly 2 is mounted on the left side of the mounting base 1. The clamping assembly 2 includes a support rod 21, a fixing sleeve 22, a first fixing block 23, a first transmission rod 24, a support plate 25, a support pad 26, a movable sleeve 27, a second fixing block 28, a second transmission rod 29, an abutment plate 210, and an insertion block 211. The abutment plate 210 is fixedly connected to the left end of the support rod 21, and the insertion block 211 is fixedly connected to the right end of the support rod 21. The right end of the movable sleeve 27 is snapped into the snap-fit groove 13. A paper tube body 3 is sleeved on the surface of the clamping assembly 2.
[0033] After the clamping component 2 is installed on the left side of the mounting base 1, the right end of the movable sleeve 27 is just locked inside the snap-fit groove 13. At this time, during the extension and retraction of the piston rod in the cylinder 11, the movable sleeve 27 will be pushed to slide left and right on the surface of the support rod 21, thereby extending or retracting the support plate 25 and the support pad 26. By adjusting the sliding distance of the movable sleeve 27, the extension distance of the support plate 25 and the support pad 26 can be adjusted, thereby fixing paper tubes of different diameters.
[0034] See Figure 2 and Figure 3 Multiple sets of fixing sleeves 22 are fixedly connected to the surface of the support rod 21. Multiple sets of first fixing blocks 23 are fixedly connected to the side of the fixing sleeves 22. A first transmission rod 24 is rotatably connected to the outer end of each set of first fixing blocks 23. Multiple sets of support plates 25 are provided on the outer side of the support rod 21. The outer end of each set of first transmission rods 24 is rotatably connected to the surface of each set of support plates 25. A support pad 26 is fixedly connected to the outer end of the support plate 25. A movable sleeve 27 is slidably connected to the surface of the support rod 21 near the right end. Multiple sets of second fixing blocks 28 are fixedly connected to the surface of the movable sleeve 27. A second transmission rod 29 is rotatably connected to the outer end of each set of second fixing blocks 28. The outer end of each second transmission rod 29 is rotatably connected to the right end of each set of support plates 25.
[0035] Specifically, during the process of fixing the paper tube body 3, the movable sleeve 27 is first slid to the rightmost end. The movable sleeve 27 drives multiple sets of second fixing blocks 28 to move to the right, thereby pulling the inner end of the second transmission rod 29 to the right, and then pulling the support plate 25 to the right. At this time, the inner end of multiple sets of first transmission rods 24 will rotate to the right around the first fixing block 23, causing multiple sets of support plates 25 to move inward at the same time, and retracting the support plate 25 and the support pad 26 inward.
[0036] After the support plate 25 and support pad 26 are returned to their original state, the paper tube body 3 is placed on the outside of the support pad 26. Then, the movable sleeve 27 is pushed to the farthest point, which in turn pushes the inner end of the second transmission rod 29 to the left. Together with the first transmission rod 24, the support plate 25 is pushed to the left, so that it is spread outwards. The paper tube body 3 is supported and fixed from the inside out. Since the multiple sets of support pads 26 are all arc-shaped, they can fit well with the inner wall of the paper tube body 3 after being spread out, so that the paper tube body 3 can maintain the best cylindricity during the polishing process, effectively improving the polishing quality of the paper tube body 3.
[0037] See Figure 2 and Figure 4 An electric motor 14 is fixedly mounted on the right side surface of the mounting base 1. A connecting block 15 is fixedly connected to the left end of the output end of the electric motor 14. A plug-in groove 16 is opened on the surface of the connecting block 15. The plug-in block 211 is plugged into the plug-in groove 16 and fixed. Threaded holes 17 are opened on the upper surface of the connecting block 15 at the front and rear sides of the plug-in groove 16. Locking screws 18 are threaded inside the threaded holes 17. A positioning block 19 is sleeved on the surface of the locking screws 18.
[0038] In addition, during the installation of the clamping assembly 2, first rotate the two positioning blocks 19 to the outer end, then directly insert the plug block 211 into the inside of the plug slot 16, and then rotate the positioning block 19 to the upper side of the plug block 211 to tightly fix the plug block 211 inside the plug slot 16, thereby installing and fixing the clamping assembly 2. In order to improve the fixing strength of the plug block 211, the locking screw 18 can be tightened to prevent the positioning block 19 from shifting and further improve the stability of the clamping assembly 2.
[0039] Meanwhile, during the polishing process, the output end of the electric motor 14 drives the connecting block 15 to rotate, the connecting block 15 drives the clamping assembly 2 to rotate, and then drives the paper tube body 3 to rotate, thereby improving the uniformity of polishing the paper tube body 3.
[0040] The working principle of this utility model is as follows: By using the cylinder 11 to drive the movable sleeve 27 to slide left and right, it cooperates with the first fixed block 23, the first transmission rod 24, the second fixed block 28 and the second transmission rod 29 to drive multiple sets of support plates 25 to move inward or outward. By adjusting the opening and closing degree of the support plates 25, paper tubes of different diameters can be externally supported and clamped, improving adaptability and eliminating the need for frequent replacements, thus effectively improving the grinding efficiency of the paper tube body 3. By inserting the plug 211 into the plug slot 16 and then rotating the positioning block 19 to the upper side of the plug 211, the plug 211 can be locked and fixed, which facilitates quick fixation of the clamping assembly 2 and effectively improves the convenience of assembling and disassembling the clamping assembly 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
