Description

Technical Field

[0001] This utility model relates to the field of indentation devices, specifically an indentation device for paper tube production. Background Technology

[0002] Paper tubes are tubular objects made from paper. Most paper tubes are spiral paper tubes or seamless paper tubes. In production and daily life, paper tubes are usually used for winding yarn, cloth or paper products. Compared with metal tubes, paper tubes need to be creasing during the production process to meet the needs of use. Therefore, there is a special need for an efficient creasing device for paper tube production.

[0003] According to publicly available patent 202320943304.6, a high-efficiency creasing device for paper tube production includes a worktable and a fixing mechanism. A fixing block is fixedly connected to the outer surface of the worktable, a fixing roller is fixedly connected to the outer surface of one end of the connecting shaft, and a baffle is fixedly connected to the outer surface of one end of the fixing roller. The outer surface of the worktable is equipped with both the fixing mechanism and the creasing mechanism. In realizing this invention, the inventors discovered that at least the following problems remain unsolved in the prior art: With the fixing mechanism, the paper tube is first placed on the outer surface of the fixing roller, and then an external power supply is connected to make the first electric slide... The block slides along the outer surface of the first electric slide rail. The sliding of the first electric slider on the surface of the first electric slide rail causes the first electric slider to push the fixed sleeve towards the fixed roller via the fixed column. This causes the fixed sleeve to fit against the outer surface of the outer rotating shaft of the fixed roller and clamp it, solving the problem of the complex fixation of the fixed roller. In traditional paper tube production creasing devices, the creasing component is a single, integral structure that cannot be adjusted according to the spacing, number, or shape of the creasing marks. When the spacing, number, or shape of the creasing marks changes, a new, integral creasing component needs to be replaced, thus limiting the range of the paper tube during the creasing process. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a creasing device for paper tube production. This solves the technical problem that the current creasing device for paper tube production has a single, integral structure for the creasing component, which cannot be adjusted according to the spacing, number, or shape of the creasing. When the spacing, number, or shape of the creasing changes, a new integral creasing component needs to be replaced, thus limiting the range of the paper tube in the creasing process.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a creasing device for paper tube production is designed, including a creasing table. Two mounting brackets are slidably connected to the upper surface of the creasing table. A drive motor is fixedly connected to one side of the two mounting brackets. The output end of the drive motor movably passes through one end of the mounting bracket and is fixedly connected to a drive shaft. The other end of the drive shaft is rotatably connected to the other end of the mounting bracket. Multiple creasing discs are slidably connected to the outside of one drive shaft. A connecting plate is fixedly connected to one side of the multiple creasing discs. A limit bolt is threaded inside the connecting plate. One end of the limit bolt abuts against the outer surface of one drive shaft. A spiral creasing blade is fixedly connected to the outer surface of the other drive shaft.

[0006] Preferably, the surface of the indentation table has two symmetrical track grooves, and a lead screw is rotatably connected inside the two track grooves. One end of the lead screw moves through one end of the track groove and is fixedly connected to the output end of the servo motor. The mounting end of the servo motor is fixedly connected to the outer side of the indentation table, and the external threads of the two lead screws are connected to the bottom end of the mounting bracket.

[0007] Preferably, a support plate is fixedly connected to the middle of one side of the indentation table, a baffle is rotatably connected to one side of the support plate, and a carrier plate is fixedly connected to the other side of the baffle.

[0008] Preferably, limit posts are fixedly connected to all four sides of the carrier plate, and springs are sleeved on the outside of the limit posts. The other end of the springs is connected to an abutment block through a through hole.

[0009] Preferably, the through hole is located inside one end of the abutment block, the other end of the spring is inserted into the through hole, and two limiting plates are fixedly connected to both sides of the abutment block.

[0010] Preferably, the other end of the abutment block is movably connected to the slot of the sleeve post, the sleeve post is fitted on the outside of the carrier plate, one end of which is fixedly connected to the other side of the baffle plate, and the slots are evenly distributed around the sleeve post.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] When the paper tube needs to be creasing at intervals, this utility model first adjusts the number and spacing of the creasing discs according to the length of the paper tube and the spacing of the creasing intervals. The operator first loosens the limiting bolts, then moves the excess creasing discs to the mounting bracket end away from the sleeve column, adjusts the spacing of the remaining creasing discs, and tightens the limiting bolts on all creasing discs to fix them in place. Then, a drive motor drives a drive shaft to rotate, which in turn drives the creasing discs to rotate, thus creasing the paper tube. This allows the spacing and number of creasing discs to be adjusted according to the spacing and number of paper tube creasing intervals, increasing the range of the creasing device during the paper tube creasing process. When the paper tube needs to be spirally creasing, the drive motor drives another drive shaft to rotate, which in turn drives the spiral creasing blades to rotate, thus spirally creasing the paper tube. This further increases the range of the creasing device during the paper tube creasing process, improving the convenience of the creasing device during paper tube creasing.

[0013] When the position of the creasing disc or spiral creasing blade is adjusted, the output of the servo motor will drive the lead screw to rotate, and the lead screw will then drive the mounting bracket to move towards the position of the sleeve column. This allows the position of the creasing disc or spiral creasing blade to be adjusted according to the diameter of the paper tube, which helps to further improve the convenience of the creasing device in the process of creasing the paper tube.

[0014] When the paper tube needs to be fixed, first put one end of the paper tube onto one end of the sleeve post, and then move it to the other end of the sleeve post. During this process, the paper tube will exert a squeezing force on the abutment block, so that the abutment block is housed inside the slot. During this process, the abutment block will squeeze the spring, and the limiting post will restrict the position of the spring. When one end of the paper tube abuts against the side of the baffle, the spring will generate a rebound force on the abutment block, so that the paper tube is fixed on the sleeve post, avoiding the phenomenon of the paper tube deviating from the sleeve post during the indentation process. When the paper tube needs to be removed from the sleeve post, a pulling force can be applied directly from one end of the paper tube to remove the paper tube from the sleeve post, which helps to improve the convenience of the paper tube in the disassembly and assembly process.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] Example 1: A creasing device for paper tube production, see [link to example]. Figures 1 to 5 The system includes a creasing table 1, with two mounting brackets 11 slidably connected to its upper surface. A drive motor 12 is fixedly connected to one side of each mounting bracket 11. The output end of the drive motor 12 movably passes through one end of the mounting bracket 11 and is fixedly connected to a drive shaft 13. The other end of the drive shaft 13 is rotatably connected to the other end of the mounting bracket 11. Multiple creasing discs 14 are slidably connected to the outside of one drive shaft 13. A connecting plate 15 is fixedly connected to one side of each creasing disc 14. A limit bolt 16 is threaded inside the connecting plate 15. One end of the limit bolt 16 abuts against the outer surface of one drive shaft 13. A spiral creasing blade 17 is fixedly connected to the outer surface of the other drive shaft 13. When the paper tube needs to be creasing at intervals, the number and spacing of the creasing discs 14 are first adjusted according to the length of the paper tube and the creasing interval. The operator then first loosens the limit bolt 16 and removes any excess creasing material. The disc 14 is moved to the end of the mounting bracket 11 away from the sleeve 29. The spacing of the remaining creasing discs 14 is then adjusted, and the limiting bolts 16 on all the creasing discs 14 are tightened to fix the creasing discs 14. Then, the drive motor 12 drives a drive shaft 13 to rotate, and the drive shaft 13 drives the creasing discs 14 to rotate, thereby creasing the paper tube. This allows the spacing and number of creasing discs 14 to be adjusted according to the spacing and number of paper tube creasing, increasing the range of the creasing device in the paper tube creasing process. When the paper tube needs to be spirally creasing, the drive motor 12 drives another drive shaft 13 to rotate, and the other drive shaft 13 drives the spiral creasing blade 17 to rotate, thereby spirally creasing the paper tube, further increasing the range of the creasing device in the paper tube creasing process and improving the convenience of the creasing device in the paper tube creasing process.

[0024] For details, see Figures 1 to 3Two track grooves 18 are symmetrically opened on the surface of the creasing table 1. The two track grooves 18 are rotatably connected to lead screws 19. One end of the lead screw 19 moves through one end of the track groove 18 and is fixedly connected to the output end of the servo motor 2. The mounting end of the servo motor 2 is fixedly connected to the outer side of the creasing table 1. The external threads of the two lead screws 19 are connected to the bottom end of the mounting frame 11. When the position of the creasing disc 14 or the spiral creasing blade 17 is adjusted, the output end of the servo motor 2 will drive the lead screw 19 to rotate, and then the lead screw 19 will drive the mounting frame 11 to move towards the position of the sleeve 29. This allows the position of the creasing disc 14 or the spiral creasing blade 17 to be adjusted according to the diameter of the paper tube, which helps to further improve the convenience of the creasing device in the process of creasing the paper tube.

[0025] Further, see Figures 3 to 5 A support plate 22 is fixedly connected to the middle of one side of the indentation table 1. A baffle 23 is rotatably connected to one side of the support plate 22. A carrier plate 24 is fixedly connected to the other side of the baffle 23. Limiting posts 25 are fixedly connected to all four sides of the carrier plate 24. A spring 26 is sleeved on the outside of the limiting post 25. The other end of the spring 26 is connected to a stop block 28 through a through hole 27. The through hole 27 is located inside one end of the stop block 28. The other end of the spring 26 is inserted into the through hole 27. Two limiting plates 21 are fixedly connected to both sides of the stop block 28. The other end of the stop block 28 is movably connected to the slot 3 of the sleeve post 29. The sleeve post 29 is sleeved on the outside of the carrier plate 24. One end is fixedly connected to the other side of the baffle 23. The slots 3 are evenly distributed around the sleeve post 29. When the paper tube needs to be fixed... First, one end of the paper tube is placed on one end of the sleeve post 29, and then moved to the other end of the sleeve post 29. During this process, the paper tube will exert a squeezing force on the abutment block 28, so that the abutment block 28 is housed inside the slot 3. During this process, the abutment block 28 will squeeze the spring 26, and the limiting post 25 will restrict the position of the spring 26. When one end of the paper tube abuts against the side of the baffle 23, the spring 26 will exert a rebound force on the abutment block 28 so that the paper tube is fixed on the sleeve post 29, avoiding the phenomenon of the paper tube deviating from the sleeve post 29 during the indentation process. When the paper tube needs to be removed from the sleeve post 29, a pulling force can be applied directly from one end of the paper tube to remove the paper tube from the sleeve post 29, which helps to improve the convenience of the paper tube in the disassembly and assembly process.

[0026] It should be noted that one side of the abutment block 28 is beveled, which makes it easier for the paper tube to squeeze the abutment block 28 so that the abutment block 28 can be inserted into the inside of the paper tube.
