Clamping mechanism for processing living paper

Abstract

This utility model discloses a clamping mechanism for processing tissue paper, including a mounting base. Adjusting sleeves are rotatably mounted on both sides of the mounting base for clamping and fixing the paper strip. A set of bushings is mounted on the outer side of each of the two adjusting sleeves. A bidirectional threaded rod is rotatably mounted between the two corresponding bushings in the same set, and the two clamping rods are threadedly connected to the bidirectional threaded rods. After the end of the paper strip passes through the two clamping rods, a micro-motor drives the clamping rods to achieve initial flexible clamping through the clamping sleeves. Then, the driving motor drives the adjusting sleeves to rotate one to two turns, thereby winding and tightening the clamped paper strip so that the clamping end of the paper strip can be tightly attached to the outer walls of the two clamping sleeves. Furthermore, a pressure sensor can be used to adjust the clamping force of the clamping rods to accommodate paper strips of different thicknesses, ensuring the stability of the paper strip clamping and preventing the paper strip from sagging or loosening during transmission, thus facilitating the smooth pulling and transmission of the paper strip.

Description

Technical Field

[0001] This utility model relates to the field of tissue paper processing technology, specifically a clamping mechanism for tissue paper processing. Background Technology

[0002] In the process of processing tissue paper, the stability of the paper tape clamping and conveying process directly affects the processing accuracy and production efficiency of the product.

[0003] Because existing clamping methods used in tissue paper processing mostly employ a single clamping structure, simply clamping and fixing the ends of the paper strip without subsequent auxiliary tensioning and stabilizing mechanisms, the following issues arise. Firstly, since the paper strip is held in place solely by the clamping force of the clamping rods, if the clamping force is too weak, the paper strip is prone to sagging, loosening, or even detaching from the clamping mechanism during transport due to its own weight or external forces. Conversely, if the clamping force is too strong, it can easily cause edge damage or tearing of the paper strip, affecting product quality. Secondly, the lack of effective winding and tightening measures after clamping the ends of the paper strip results in gaps between the clamping end and the clamping rods, preventing a tight, tensioned fit and thus affecting the stability of subsequent conveying and cutting processes.

[0004] Therefore, there is an urgent need for a clamping mechanism that combines flexible clamping and winding tightening functions to ensure the stability of paper tape clamping and avoid damage to the paper tape, thereby overcoming the shortcomings of existing technologies. Utility Model Content

[0005] In view of the fact that the existing paper tape clamping structure is relatively simple and has certain limitations in practical use, this utility model provides a clamping mechanism for processing household paper that has both flexible clamping and winding tightening functions.

[0006] The technical implementation scheme of this utility model is as follows: a clamping mechanism for processing tissue paper includes a mounting base, with adjusting sleeves rotatably arranged on both sides of the mounting base. Each adjusting sleeve has a guide groove in its middle, and two clamping rods are slidably arranged within the guide grooves for clamping and fixing the paper strip. The mechanism also includes a clamping structure, which includes bushings. A set of bushings is arranged on the outer side of each of the two adjusting sleeves, and a bidirectional threaded rod is rotatably arranged between corresponding bushings in the same set. The two clamping rods are threadedly connected to the bidirectional threaded rods. A micro motor is also mounted on the outer side of each of the two adjusting sleeves. A worm gear is connected to the output shaft of each micro motor. One end of the worm gear is connected to the other side of the adjusting sleeve through the bushing, and the worm gear is rotatably sleeved with the bushing. A worm wheel is sleeved in the middle of the bidirectional threaded rod, and the worm gear and worm wheel are engaged in transmission. A rotating component is arranged on one side of the mounting base to drive the adjusting sleeves to rotate synchronously with the clamping rods, thereby winding and tightening the end of the clamped paper strip.

[0007] More preferably, the rotating assembly includes a drive motor, a drive gear, and a driven gear. The drive motor is provided on one side of the mounting base, the drive gear is provided at the output end of the drive motor, and the driven gear is fitted on the outer periphery of the adjusting sleeve near the drive motor, and the drive gear meshes with the driven gear.

[0008] More preferably, the clamping rod has slots at both ends that slide with the guide groove.

[0009] More preferably, it also includes a positioning sleeve and a pressure sensor. Positioning sleeves are respectively provided on opposite sides of both ends of the clamping rod. A pressure sensor and a contact rod are respectively provided inside the positioning sleeve. When the clamping rods are closed together, the pressure sensor can abut against the contact rod.

[0010] More preferably, it also includes a sleeve, which is detachably fitted onto the clamping section of the clamping rod.

[0011] More preferably, it also includes a spring, with a spring connecting the two corresponding positioning sleeves on the same side.

[0012] The beneficial effects of this utility model are as follows: After the end of the paper tape passes through the two clamping rods, the clamping rods are first driven by a micro motor to achieve flexible initial clamping through the clamping sleeves. Then, the adjusting sleeve is rotated one to two turns by the drive motor, which can wind and tighten the clamped paper tape so that the clamping end of the paper tape can be tightly attached to the outer wall of the two clamping sleeves. In addition, the clamping force of the clamping rods can be adjusted accordingly by the pressure sensor to adapt to paper tapes of different thicknesses. This ensures the stability of the paper tape clamping and prevents the paper tape from sagging or loosening during transmission, which is conducive to the smooth pulling and transmission of the paper tape.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] This utility model provides a clamping mechanism for processing household paper, see below. Figures 1 to 4 As shown, the device includes a mounting base 1, with horizontally distributed adjusting sleeves 2 rotatably mounted on both sides of the mounting base 1. Each adjusting sleeve 2 has an axially penetrating guide groove 20 in its center, within which two clamping rods 3 are slidably mounted for clamping and fixing the paper tape 100. The clamping rods 3 have slots 30 at both ends that slidably engage with the guide grooves 20, providing directional guidance. The device also includes a clamping structure comprising bushings 32. A set of bushings 32 is mounted on the outer side of each of the two adjusting sleeves 2, with three bushings in each set. A bidirectional threaded rod 33 is rotatably mounted between corresponding bushings 32 in the same set, and the two clamping rods 3 are threadedly connected to the bidirectional threaded rod 33. Finally, a clamping sleeve 31 is included, detachably fitted onto the clamping section of the clamping rods 3, enabling flexible clamping of the paper tape 100's clamping surface, thus protecting the paper tape 100's surface and preventing... Obvious indentations appear; micro motors 4 are also installed on the outer sides of the two adjusting sleeves 2 respectively. The output shaft end of the micro motor 4 is connected to a worm gear 40. One end of the worm gear 40 is connected to the other side of the adjusting sleeve 2 through a bushing 32. The worm gear 40 and the bushing 32 are rotatably sleeved. A worm wheel 41 is sleeved in the middle of the bidirectional threaded rod 33, and the worm gear 40 and the worm wheel 41 are engaged in transmission. The micro motor 4 drives the worm gear 40 to drive the worm wheel 41 to rotate in the forward or reverse direction, so that the bidirectional threaded rod 33 drives the two clamping rods 3 on it to move closer to each other or spread out, which is used to conveniently and firmly clamp paper tapes 100 of different thicknesses. A rotating component is provided on one side of the mounting base 1, which is used to drive the adjusting sleeve 2 to drive the clamping rods 3 to rotate synchronously, so as to wind and tighten the end of the paper tape 100 that has been initially clamped, thereby improving the stability of the paper tape 100 clamping and facilitating the subsequent smooth and orderly processing of the paper tape 100.

[0020] Furthermore, the rotating assembly includes a drive motor 34, a drive gear 35, and a driven gear 36. The drive motor 34 is located on one side of the mounting base 1, and the drive gear 35 is located at the output end of the drive motor 34. The driven gear 36 is fitted around the outer periphery of the adjusting sleeve 2 near the drive motor 34, and the drive gear 35 meshes with the driven gear 36. By controlling the drive motor 34 to drive the drive gear 35 and the driven gear 36 to rotate, the adjusting sleeve 2 drives the two clamping rods 3 on it to rotate synchronously one to two revolutions, thereby enabling the initial clamping and fixing of the paper tape 100 to be wound and wound up, which is beneficial to further improve the stability of the clamping of the paper tape 100.

[0021] In addition, it also includes positioning sleeves 5 and pressure sensors 7. Positioning sleeves 5 are respectively provided on opposite sides of both ends of the clamping rods 3. Pressure sensors 7 and contact rods are respectively provided inside the positioning sleeves 5. When the two clamping rods 3 are brought close together, the pressure sensors 7 can abut against the contact rods, thereby sensing the clamping force between the two clamping rods 3. This is beneficial for real-time control of the clamping state and is suitable for clamping paper tapes 100 of different specifications. It also includes springs 6. Springs 6 are connected between the two positioning sleeves 5 on the same side to cooperate with the pressure sensors 7 and contact rods, providing instantaneous buffer protection.

[0022] The end of the paper tape 100 is passed between the two clamping rods 3. After the micro motor 4 is started, it drives the bidirectional threaded rod 33 to rotate synchronously through the meshing transmission of the worm gear 40 and the worm wheel 41. This causes the clamping rods 3 to move their clamping sleeves 31 together. During this clamping process, the paper tape 100 can be flexibly clamped and fixed by the cooperation of the spring 6 and the clamping sleeves 31. In actual operation, the pressure feedback of the clamping force of the paper tape 100 through the preset pressure sensor 7 can also be used to adjust the clamping force of the two clamping rods 3 according to the different thicknesses of the paper tape 100. The clamping force is adjusted accordingly to improve the overall usability. Then, the drive motor 34 is started, and the driven gear 36 and the adjusting sleeve 2 are driven by the drive gear 35 to rotate synchronously one to two revolutions. This can wind and tighten the paper tape 100 that has been initially clamped and fixed, so that the clamping end of the paper tape 100 can be tightly attached to the outer wall of the two clamps 31. This can achieve the purpose of clamping and tensioning the paper tape 100, which helps to maintain the stability of the paper tape 100 clamping and prevent the paper tape 100 from sagging or loosening during the transmission process.
