Description

Technical Field

[0001] The utility model relates to the technical field of toilet paper production equipment, in particular to an indentation device for roll paper production. Background Art

[0002] In the roll paper production process, indentation processing is a key link. By forming a specific indentation pattern on the surface of the roll paper, it not only beautifies the appearance of the product, but also enhances the convenience of using the roll paper, allowing users to more easily tear off the required length of paper.

[0003] However, in traditional roll paper production creasing equipment, the support shaft used to install the roll paper is relatively simple in design, and the roll paper is usually fixed only by friction or a simple slot structure. This design has obvious defects in the actual production process: when the roll paper is heavy or the production line speed is fast, the roll paper is prone to swing on the support shaft due to insufficient fixing force of the support shaft on the roll paper. This swing not only affects the accuracy and consistency of the creasing process, but may also cause damage to the roll paper and even cause the production line to stop, thereby reducing production efficiency and product quality.

[0004] Therefore, it is necessary to design a creasing device that can stably fix the paper roll to ensure that the paper roll maintains a smooth operation during the creasing process. Utility Model Content

[0005] The purpose of the present invention is to overcome the above technical deficiencies, propose a creasing device for roll paper production, and solve the technical problems raised in the background technology.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] Reference Figure 1 The utility model provides an indentation device for roll paper production, which mainly includes a base 1, on which an indentation bracket 2 is firmly arranged, and a pattern roller 3 and a rubber roller 4 are installed in the indentation bracket 2, which are used to form an indentation pattern on the surface of the roll paper. An adjustment chute 5 and an adjustment screw 6 are also provided on the indentation bracket 2. Both ends of the rubber roller 4 are arranged in the adjustment chute 5, and one end of the adjustment screw 6 passes through the adjustment chute 5 and is rotatably connected to the rubber roller 4. This design allows the operator to easily adjust the distance between the rubber roller 4 and the pattern roller 3 to accommodate roll paper of different specifications and thicknesses. The outside of the indentation bracket 2 is equipped with a motor 7 and an unwinding support rod 8. The output shaft of the motor 7 is connected to the pattern roller 3 to drive it to rotate; the unwinding support rod 8 is installed with a fixing mechanism 9 to solve the problem of unstable fixation of the roll paper in traditional equipment.

[0022] Reference Figure 2 、 Figure 3 The core design of the fixing mechanism 9 includes a core rod 901, which is fixedly connected to the top of the unwinding support rod 8; a coaxial inner tube 903 and an outer tube 904 are rotatably provided on the core rod 901, and bearings 902 are also provided on the core rod 901 at both ends of the inner tube 903, the inner ring of the bearing 902 is fixedly connected to the core rod 901, and the outer ring is fixedly connected to the inner tube 903; a locking mechanism 905 is provided on the end of the outer tube 904 adjacent to the unwinding support rod 8, and a compression spring 10 is provided between the locking mechanism 905 and the unwinding support rod 8; a support tube groove 907 is provided on the outer tube 904, and an outer support piece 906 is installed in the tube groove 907, one end of which is rotatably connected to the inner wall of the support tube groove 907, so that it can be flexibly opened or closed when needed; refer to Figure 4 The inner tube 903 is provided with a guide chute 908 that directly faces the support tube groove 907. A roller 909 is also provided on the side of the outer support plate 906 adjacent to the guide chute 908. A buffer spring 916 is also provided between the roller 909 and the outer support plate 906. In actual application, the inner tube 903 can be made of magnetic material, and the roller 909 is designed as a magnet. This design allows the roller 909 to be more stably adsorbed on the inner tube 903 during movement, thereby improving the fixing effect and overall stability of the support tube mechanism.

[0023] When the locking mechanism 905 drives the outer tube 904 to move toward the unwinding support rod 8, the roller 909 rises along the inclined surface of the guide inclined groove 908, thereby opening the outer support piece 906 and pressing it against the inner wall of the paper roll. When the locking mechanism 905 moves to the extreme position, the outer tube is locked, thereby achieving a stable fixing effect. In actual application, the outer support piece 906 is made of wear-resistant and elastic material to ensure that it can effectively press against the inner wall of the paper roll for a long time.

[0024] Reference Figure 5 、 Figure 6 The locking mechanism 905 includes a locking ring 910, in which a locking tongue 911 and a return spring 912 are provided. The locking tongue 911 passes through the inner annular surface of the locking ring 910 and cooperates with the locking groove 913 on the inner tube 903. An unlocking block 914 that cooperates with the locking tongue 911 is also slidably provided in the locking groove 913. The end of the unlocking block 914 is triangular in design, which is convenient for mating or separating with the locking tongue 911; the end of the locking groove 913 adjacent to the outer tube 904 is a groove design that fits with the unlocking block 914, and a tension spring 915 is also provided between the unlocking block 914 and the other end of the locking groove 913. The setting of the tension spring 915 enables the unlocking block 914 to maintain contact with the end wall of the locking groove 913 when there is no external force.

[0025] When installing the paper roll, the locking mechanism 905 is pushed to move toward the unwinding support rod 8, and the compression spring 10 is compressed. When the lock tongue 911 moves to the top of the locking groove 913, it is inserted into the locking groove 913 under the action of the return spring 912 to achieve locking ( Figure 5 When the paper roll is removed, the locking mechanism 905 is pushed further toward the unwinding support rod 8. At this time, the lower end of the locking tongue 911 rises along the inclined surface of the unlocking block 914 and passes over its upper end to the other side. Then, the locking mechanism 905 is released. Under the restoring force of the compression spring 10, the locking tongue 911 pushes the unlocking block 914 to move and fit into the groove of the locking groove 913. Then, the locking tongue 911 rises along the inclined surface of the unlocking block 914 and disengages from the locking groove 913, thereby achieving unlocking.

[0026] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
