Description

Technical Field

[0001] This utility model relates to the field of roller support structure, specifically to unwinding roller brake. Background Technology

[0002] With the continuous development of industrialization, the garment industry is gradually transforming from a traditional labor-intensive industry to one of industrialization and automation. Since most fabrics are produced and transported in rolls, an important process at the user's factory is to unroll the rolls into multi-layered, flat sheets for efficient cutting. In the garment-making process, fabric spreading and cutting play a crucial role. Only regular cut pieces can be sewn into garments that meet specifications. If the cut pieces are not regular, even the best sewing machine and the most skilled sewing worker will not be able to sew high-quality garments. Fabric spreading is the prerequisite for fabric cutting and the first step in garment making. The quality of fabric spreading directly determines the quality of the finished garment.

[0003] For example, our company's patent with authorization announcement number CN217376776U discloses a multi-roll fabric pulling structure, comprising: a base and multiple fabric pulling mechanisms; the fabric pulling mechanism comprises: a fabric roll support assembly for rotatably supporting the fabric roll; a guide assembly disposed between two support crossbars; an adjustment assembly for adjusting it to move along the guide assembly; two support uprights, respectively vertically disposed on the two support crossbars; a transition rod, horizontally disposed between the two support uprights; a fixing rod, horizontally disposed between the two support uprights; and an opposite-side photoelectric sensor disposed on one of the two support uprights, located between the transition rod and the fixing rod; the fabric roll supported on the fabric roll support assembly sequentially passes below the transition rod, above the opposite-side photoelectric sensor and the fixing rod, thereby being tensioned by the transition rod and the fixing rod during the fabric roll being pulled.

[0004] The multi-roll fabric pulling structure of the aforementioned patent can improve the efficiency of fabric pulling and allows for pulling multiple rolls of fabric together. It also enables independent control of the edge alignment for each roll of fabric. However, the disadvantage of the aforementioned patent is that the support shaft of the fabric roll is supported by a fabric threading rod. This unpowered unwinding structure cannot control the rotation speed of the fabric roll.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a brake for the unwinding roller to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The unwinding roller brake includes a fabric guide rod. A mounting plate is located at the top front end of the fabric guide rod, and the mounting plate is inclined. A connector is bolted to the top of the mounting plate, and a rotating wheel seat is fixedly mounted on the top of the connector. A pressure-bearing rotating wheel is rotatably connected to the rotating wheel seat via a rotating shaft. Simultaneously, a movable plate is located at the top rear side of the fabric guide rod. The movable plate is U-shaped, and its bottom is rotatably connected to the fabric guide rod via a rotating shaft. An anti-detachment shaft is located forward on the top left side of the movable plate, and an anti-detachment rotating wheel is rotatably connected to the anti-detachment shaft. A brake pad mounting plate extends forward from the top right side of the movable plate, and a brake pad is fixedly mounted on the brake pad mounting plate. The movable plate also has positioning holes, and the fabric guide rod has arc-shaped waist holes. The positioning holes and waist holes are correspondingly arranged, and positioning bolts are fixedly connected to the positioning holes and waist holes.

[0009] Furthermore, the rear side of the mounting plate is welded to the front end of the fabric-threading rod.

[0010] Furthermore, the brake pads are bonded to the surface of the brake pad mounting plate.

[0011] Furthermore, the brake pads are made of resin material.

[0012] Furthermore, since there are two positioning holes, there are also two corresponding waist holes, and they are set one-to-one.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0022] This solution is mainly used to improve the structure of the fabric threading rod in the existing technology so that it can control the rotation speed of the supporting shaft;

[0023] Please see Figure 1-5 The unwinding roller brake includes a fabric threading rod 1. The top front end of the fabric threading rod 1 is provided with a mounting plate 2. The mounting plate 2 is inclined. A plug-in seat 201 is fixedly installed on the top of the mounting plate 2 by bolts. A rotating wheel seat 3 is fixedly installed on the top of the plug-in seat 201. A pressure-bearing rotating wheel 301 is rotatably connected to the rotating wheel seat 3 by a rotating shaft.

[0024] Meanwhile, a movable plate 4 is provided on the rear side of the top of the fabric threading rod 1. The movable plate 4 is U-shaped in general. The bottom of the movable plate 4 is rotatably connected to the fabric threading rod 1 through a pivot. An anti-detachment shaft 401 is provided on the top left side of the movable plate 4. An anti-detachment rotating wheel 402 is rotatably connected to the anti-detachment shaft 401.

[0025] A brake pad mounting plate 403 is provided extending forward from the top right side of the movable plate 4, and a brake pad 404 is fixedly mounted on the brake pad mounting plate 403; the brake pad 404 is made of resin material.

[0026] In this solution, the movable plate 4 is provided with a positioning hole 405, and the fabric rod 1 is provided with an arc-shaped waist hole 406. The positioning hole 405 and the waist hole 406 are provided in a corresponding manner, and the positioning bolt 407 is fixedly connected in the positioning hole 405 and the waist hole 406.

[0027] In this solution, there are two positioning holes 405, and there are also two corresponding waist holes 406, which are set one-to-one.

[0028] like Figure 6As shown, when this solution is used, the support shaft 9 is placed on the pressure roller 301. At this time, the lower part of the support shaft 9 is close to the pressure roller 301, and the right side of the support shaft 9 rests on the brake pad 404. Meanwhile, there is an anti-detachment roller 402 on the left side of the support shaft 9 to prevent the support shaft 9 from detaching.

[0029] When using this solution, if faster unwinding is required, the brake needs to be loosened slightly to allow the support shaft 9 to rotate more smoothly. This can be achieved by rotating the movable plate 4 counterclockwise and then fixing the positioning bolt 407. At this point, the brake pad 404 is more vertical, and more of the weight of the support shaft 9 is borne by the pressure roller 301, resulting in less pressure between the support shaft 9 and the brake pad 404. Consequently, the friction between the support shaft 9 and the brake pad 404 is also reduced, allowing the support shaft 9 to rotate more smoothly.

[0030] Conversely, if the unwinding needs to be slower, the brake needs to be tighter, meaning the support shaft 9 needs to rotate more heavily. In this case, the movable plate 4 can be rotated clockwise, and then the positioning bolt 407 can be fixed. At this time, the brake pad 404 is more horizontal, and the pressure borne by the pressure roller 301 will be distributed more between the support shaft 9 and the brake pad 404. The friction between the support shaft 9 and the brake pad 404 will also increase, making it more difficult for the support shaft 9 to rotate.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
