Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile machinery technology, and more specifically, it relates to a slitting device for processing heating pad backing. Background Technology
[0002] The backing of pediatric fever patches is often made of breathable, soft, and comfortable medical non-woven fabric. Before final application, this type of backing is rectangular, so the non-woven fabric needs to be cut into strips of equal width, and then the strips are cut into equal lengths to obtain a rectangular sheet structure.
[0003] Traditional fabric slitting machines can slit non-woven materials and adjust the axial position of the slitting ring blades to achieve adjustable slitting width. However, each slitting blade needs to be adjusted individually, which is not only cumbersome but also results in inconsistent spacing between adjacent blades, large errors, and poor overall performance. Therefore, this invention proposes a slitting device for processing heating pad backing. Utility Model Content

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0016] Example 1 See Figure 1 and Figure 2As shown, the slitting device for processing heating patch backing involved in this embodiment includes a fabric slitting machine (not shown), on which a fabric slitting roller is provided. The fabric slitting roller includes a roller shaft body 1, one end of which is a smooth rod portion 101 and the other end is a stud portion 102. A fixed limiting member 2 is provided on the smooth rod portion 101, and a movable limiting member 3 is provided on the stud portion 102. A plurality of self-adjusting slitting components 4 are provided between the movable limiting member 3 and the fixed limiting member 2.
[0017] Furthermore, the self-adjusting slitting assembly 4 includes a blade cylinder 401 slidably connected to the roller body 1. One end of the blade cylinder 401 is provided with a blade fixing retaining ring 402, and the other end is provided with a blade movable retaining ring 403. The inner wall surface of the blade movable retaining ring 403 is provided with internal threads, and the outer wall surface of the blade cylinder 401 is provided with matching external threads. The blade movable retaining ring 403 is threadedly connected to the blade cylinder 401. A circular slitting blade 404 is sleeved on the blade cylinder 401. The circular slitting blade 404 is located between the blade fixing retaining ring 402 and the blade movable retaining ring 403. The self-adjusting slitting assembly 4 also includes an elastic element 405 sleeved on the roller body. The elastic element 405 is a compression spring, and one end of the elastic element 405 is connected to the blade fixing retaining ring 402.
[0018] Furthermore, the fixed limiting member 2 includes a fixed shaft end retaining ring 201 that is sleeved on the smooth rod portion and moves axially relative to it, and a first locking sleeve 202. The first locking sleeve 202 is connected to the fixed shaft end retaining ring 201, and a set screw 203 with its end abutting against the smooth rod portion 101 is threaded onto the first locking sleeve 202.
[0019] Furthermore, the movable limiting member 3 includes a movable shaft end retaining ring 301 that is sleeved on the stud portion and moves axially relative to it, and a second locking sleeve 302 that is threadedly connected to the stud portion. The second locking sleeve 302 is connected to the movable shaft end retaining ring 301, and the side of the second locking sleeve 302 is provided with a swivel groove 303.
[0020] In this embodiment, the fixed limiting member 2 is fixed to the roller body 1 under the locking action of the set screw 203, and the two do not move axially relative to each other. The various self-adjusting slitting components 4 arranged between the fixed limiting member 2 and the movable limiting member 3 are subjected to axial extrusion force, which can change the distance between them.
[0021] When the movable limiting member 3 moves toward the fixed limiting member 2, the elastic elements on each self-adjusting slitting component 4 are compressed, and the distance between two adjacent annular slitting blades 404 decreases; when the movable limiting member 3 moves away from the fixed limiting member 2, the elastic elements on each self-adjusting slitting component 4 deform and reset, and extend appropriately, and the distance between two adjacent annular slitting blades 404 increases.
[0022] The movable limiting member 3 moves as follows: using an external turning tool, insert one end of it into the turning groove 303, apply a tangential force along the second locking sleeve 302, causing it to rotate the entire movable limiting member 3. Through threaded transmission, the movable limiting member 3 can move axially relative to the roller body 1.
[0023] The annular slitting blade 404 on the self-adjusting slitting assembly 4 is detachable from the assembly body. It can be removed by first unscrewing the blade retaining ring 403 and then taking off the annular slitting blade 404, which facilitates replacement or maintenance.
[0024] The present invention relates to a slitting device for processing heating pad backing. The slitting width of the slitting device is adjustable, making it suitable for slitting fabrics of different widths. Furthermore, one end of the roller body is unidirectionally adjustable, and through linkage, all the annular slitting blades can be adjusted in a coordinated manner, making adjustment quick and convenient. In addition, by using elastic elements of the same specification, and ensuring the same force, the device achieves an equal-space adjustment function. The overall function is complete and highly practical.
