Description

Technical Field

[0001] This utility model relates to the technical field of gauze production equipment, specifically a cloth roll limiting structure. Background Technology

[0002] Gauze is a common medical supply. It is generally characterized by good breathability, softness, comfort, and low allergenicity. Gauze is used to apply to wounds after injury or surgery to stop bleeding, relieve pain, and protect the wound. In the production process, gauze fabric cut to a certain width is wound onto a fabric roll. The roll is then removed from the roll to form a standard gauze roll. This facilitates subsequent processing of the fabric and also makes the transport and storage of the gauze rolls convenient.

[0003] Existing fabric roll structures typically have fixed dimensions, meaning that a single fabric roll can usually only be used for a single width of yarn. Furthermore, during rotation, these fabric rolls are prone to misalignment due to fabric feeding deviations, resulting in unevenly rolled fabric. This directly affects subsequent cutting and storage, causing numerous difficulties in yarn production. Utility Model Content

[0006] Each of the limiting sleeves includes a positioning sleeve and a limiting baffle. The limiting baffle is fixed to the end of the positioning sleeve near the fixed sleeve, and the side of the limiting baffle near the fixed sleeve is provided with a limiting slope.

[0007] The positioning sleeve is provided with a first positioning hole, which is a threaded hole. A first positioning bolt is provided in the positioning hole. The end of the first positioning bolt passes through the first positioning hole and presses against the roller rod, thereby locking and fixing the positioning sleeve.

[0008] Furthermore, the fixing sleeve includes an inner sleeve body, an outer sleeve body, and two fixing ring pieces.

The inner ring of the fixing ring piece is connected to the inner sleeve body, and the outer ring of the fixing ring piece is connected to the outer sleeve body.

[0009] Furthermore, the inner sleeve is provided with second positioning holes at both ends, and a second positioning bolt is provided in the second positioning hole. The end of the second positioning bolt passes through the second positioning hole and presses against the roller rod, thereby locking and fixing the fixing sleeve.

[0010] Furthermore, positioning retaining rings are provided at both ends of the inner sleeve, and the two retaining rings are fixed at both ends of the inner sleeve.

[0011] Furthermore, the surface of the reel rod is provided with a strip-shaped positioning groove, the ends of the first positioning bolt and the second positioning bolt are both located in the positioning groove, and the ends of the first positioning bolt and the second positioning bolt are both pressed against the bottom of the positioning groove.

[0012] Furthermore, the positioning sleeve is also provided with a locking plane.

[0013] Furthermore, each end of the reel is provided with a mounting shaft, the two mounting shafts are coaxially arranged with the reel, and the diameter of the two reel is smaller than the diameter of the reel.

Detailed Implementation

[0023] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] Please refer to Figures 1 to 4 This utility model provides a cloth roll shaft limiting structure, including a roll shaft 1, a fixing sleeve 2, and two limiting sleeves.

[0025] The roller rod 1 is a cylindrical shaft rod. The fixed sleeve 2 and the two limiting sleeves are all sleeved on the roller rod 1. The fixed sleeve 2 and the two limiting sleeves can slide along the axial direction of the roller rod 1. The two limiting sleeves are symmetrically arranged on both sides of the fixed sleeve 2. The fixed sleeve 2 is used to support the fabric so that the fabric is rolled up and stored on the fixed sleeve 2.

[0026] Each of the limiting sleeves includes a positioning sleeve 4 and a limiting baffle 5. The limiting baffle 5 is fixed to the end of the positioning sleeve 4 near the fixed sleeve 2. The limiting baffle 5 is provided with a limiting inclined surface 51 on the side near the fixed sleeve 2. In this embodiment, the limiting inclined surface 51 is a frustum-shaped surface. As the limiting inclined surface 51 approaches the fixed sleeve 2, it gradually becomes thinner. The limiting inclined surface 51 is used to concentrate the fabric towards the middle of the two limiting inclined surfaces during the fabric storage process, which can effectively prevent the problem of unevenly rolled fabric.

[0027] The positioning sleeve 4 is provided with a first positioning hole, which is a threaded hole. A first positioning bolt 41 is provided in the positioning hole. The end of the first positioning bolt 41 passes through the first positioning hole and presses against the roll rod 1. The first positioning bolt 41 is used to lock and fix the positioning sleeve 4 after the position of the positioning sleeve 4 is adjusted. This ensures that the distance between the two limiting baffles 5 is adjustable to adapt to the rolling process of fabrics of different widths.

[0028] In a preferred embodiment, the fixing sleeve 2 includes an inner sleeve 21, an outer sleeve 22, and two fixing rings 23. The outer sleeve 22 is fitted onto the inner sleeve 21, and the two are coaxially arranged. The two fixing rings 23 are located at both ends of the two outer sleeves 22. The inner rings of the fixing rings 23 are connected to the inner sleeve 21, and the outer rings of the fixing rings 23 are connected to the outer sleeve 22. The inner sleeve has second positioning holes at both ends, and second positioning bolts 3 are provided in the second positioning holes. The ends of the second positioning bolts 3 pass through the second positioning holes and press against the roll rod 1, thereby locking and fixing the fixing sleeve 2. In the above structure, the fixing sleeve 2 can be removed from the roll rod 1 after the second positioning bolts 3 are removed, which allows the rolled gauze to be quickly and conveniently removed, improving the convenience of using the cloth roll limiting structure.

[0029] In a preferred embodiment, the inner sleeve 21 is provided with positioning retaining rings 6 at both ends, which are fixed to the two ends of the inner sleeve 21. The positioning retaining rings 6 ensure that the fixing sleeve 2 is axially fixed firmly on the roller rod 1, and also facilitate disassembly.

[0030] In a preferred embodiment, the surface of the reel rod 1 is provided with a strip-shaped positioning groove 11. The ends of the first positioning bolt 41 and the second positioning bolt 3 are both located within the positioning groove 11, and the ends of the first positioning bolt 41 and the second positioning bolt 3 are both pressed against the bottom of the positioning groove 11. The bottom of the positioning groove 11 is flat, which increases the contact area between the ends of the first positioning bolt 41 and the second positioning bolt 3 and the reel rod 1, thereby improving the reliability of the fastening of the first positioning bolt 41 and the second positioning bolt 3.

[0031] In a preferred embodiment, the positioning sleeve 4 is further provided with a locking plane 42, which facilitates the installation of the first positioning bolt 41.

[0032] In a preferred embodiment, each end of the roll rod 1 is provided with a mounting shaft 12, and the two mounting shafts 12 are coaxially arranged with the roll rod 1. The diameter of the two roll rods 1 is smaller than that of the roll rod 1. The fabric roll limiting structure also includes two rotating brackets 7. Each of the two mounting shafts 12 is fitted with a rotating bearing 8, and the two mounting shafts 12 are rotatably mounted on the two rotating brackets 7 through the rotating bearings 8. Each rotating bracket 7 is provided with a lower mounting groove, and the rotating bearing 8 is installed in the lower mounting groove. Each rotating bracket 7 is also provided with an upper cover 71, and the upper cover 71 is provided with an upper mounting groove. The upper cover 71 is fixed to the rotating bracket 7 by fastening bolts. The cooperation structure between the mounting shafts 12 and the rotating brackets 7 ensures that the roll rod 1 can rotate smoothly and allows the roll rod 1 to be easily disassembled, improving the convenience of using the fabric roll limiting structure.
