Abstract
Description
Technical Field
[0001] This utility model relates to sand washing of underwear fabrics, specifically to a sand washing device for underwear fabrics. Background Technology
[0002] Sand washing of lingerie fabrics is a special washing process that alters the appearance and feel of the fabric through specific chemical agents and mechanical friction. The sand washing process is usually carried out after the fabric has been pre-shrinked by washing. By adding alkaline reagents, the texture of the fabric surface, especially the silk surface, is disrupted, creating extremely fine fibers. Fabrics treated in this way are exceptionally soft and skin-friendly, making them very comfortable to wear. These characteristics make sand-washed fabrics ideal for lingerie manufacturing, as they not only provide a comfortable wearing experience but also enhance the fabric's aesthetic appeal.
[0003] Currently, when sand washing multiple fabrics simultaneously, all of them are directly placed into the drum. As a result, the fabrics tend to entangle with each other during the sand washing process. After the sand washing is completed, it is inconvenient to remove the entangled fabrics from the drum, which affects their use. Utility Model Content
[0004] In view of the problems in the related technologies, this utility model proposes a sand washing device for underwear fabrics to overcome the above-mentioned technical problems existing in the existing related technologies.
[0005] Therefore, the specific technical solution adopted by this utility model is as follows:
[0006] A sand washing device for underwear fabric includes a sand washing device and a washing cylinder. The inner sidewall of the washing cylinder is fixedly connected with a retaining ring and a retaining post, and the inner wall of the washing cylinder is fixedly connected with a limit block. The outer wall of the retaining post is movably connected with a first retaining tube. One end of the first retaining tube is movably connected with a connecting post, and the outer wall of the connecting post is movably connected with an installation ring.
[0007] A trapezoidal connecting groove is provided on one side of the mounting ring. A nylon mesh is fixedly connected to the inner wall of the mounting ring, and a plastic fishbone is fixedly connected to the outer wall of the nylon mesh. A connecting rod is movably connected to the inner wall of the trapezoidal connecting groove, and a limit ring is movably connected to the outer wall of the connecting rod. This can play a separating role when sand washing underwear fabrics, enabling sand washing of different types of underwear fabrics. Furthermore, the separating role during sand washing can reduce the possibility of underwear fabrics tangling together, avoiding inconvenience in handling and separating them after sand washing.
[0008] Preferably, the inner wall of the first clamping tube is provided with a clamping groove, the outer wall of the connecting column is provided with a square slot, the inner wall of the square slot is movably connected to a square rod, and one end of the connecting column is movably connected to a second clamping tube. The length of the first and second clamping tubes installed with the connecting column can be adjusted, so that they can be disassembled and assembled with the cleaning cylinder in the sand washing device to meet different usage needs. At the same time, the first and second clamping tubes can also be disassembled and assembled for easy replacement and cleaning.
[0009] Preferably, the outer wall of the connecting rod and the inner wall of the limiting ring are both provided with threads, and the connecting rod is threadedly connected to the limiting ring, which can limit the nylon mesh and facilitate disassembly and assembly, thus meeting different usage needs.
[0010] Preferably, both the first and second clamping tubes are movably engaged with the connecting post via a groove. The outer wall of the connecting post is provided with a protrusion that matches the diameter of the groove, which allows the distance between the first and second clamping tubes to be adjusted, making disassembly and assembly convenient, and also improving the tightness of the connection between the clamping tubes and the connecting post.
[0011] Preferably, the first clamping tube is movably connected to the clamping post via a clamping groove, and the outer wall of the first clamping tube is movably connected to the inner wall of the clamping ring, which can improve the stability of the connection between the first clamping tube, the clamping post, and the clamping ring, and reduce the possibility of disengagement.
[0012] Preferably, the outer wall of the square rod is provided with a rubber layer, and the square rod is tightly connected to the square slot through the rubber layer, which can improve the tightness of the fit between the square rod and the square slot, so that it can be stably installed in the connecting column.
[0013] Preferably, the number of limiting blocks and the number of nylon nets are both four, and the limiting blocks are made of hard rubber, which can limit the four nylon nets and prevent them from shifting when the fabric is squeezed during sand washing.
[0014] The beneficial effects of this utility model are as follows:
[0015] The system, consisting of a limiting block, a first clamping tube, a connecting column, an installation ring, a trapezoidal connecting groove, a nylon mesh, a plastic fishbone, a connecting rod, a limiting ring, and a second clamping tube, can separate different types of underwear fabrics during sand washing. This allows for sand washing of different types of underwear fabrics, and the separation during sand washing also reduces the likelihood of underwear fabrics tangling together, preventing inconvenience in handling and separating them after sand washing.
[0016] The first and second clamping tubes, along with the connecting column, can be adjusted in length by means of a retaining ring, a retaining post, a first clamping tube, a groove, a connecting post, a square slot, a square rod, and a second clamping tube. This allows for easy assembly and disassembly of the first and second clamping tubes with the connecting post, meeting different usage requirements. The first and second clamping tubes can also be disassembled for easy replacement and cleaning. Attached Figure Description

[0036] Furthermore, the outer wall of the square rod 10 is provided with a rubber layer, and the square rod 10 is tightly connected to the square slot 9 through the rubber layer, which can improve the tightness of the fit between the square rod 10 and the square slot 9, so that it can be stably installed in the connecting column 8.
[0037] In addition, there are four limit blocks 5 and four nylon meshes 13. The limit blocks 5 are made of hard rubber and can limit the four nylon meshes 13 to prevent them from shifting when the fabric is squeezed during sand washing.
[0038] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0039] In practical applications, the nylon mesh 13 is first installed outside the first clamping tube 6, and then the connecting rod 15 is inserted into the trapezoidal connecting groove 12 on the mounting ring 11 and positioned by the limiting ring 16. Then, the other nylon meshes 13 are installed with the first clamping tube 6 and the second clamping tube 17 in the same way. Then, the first clamping tube 6 and the second clamping tube 17 are respectively clamped and installed with the connecting post 8. After the whole is placed into the washing cylinder 2, the first clamping tube 6 is clamped with the clamping post 4 and further positioned by the clamping ring 3. After adjusting the second clamping tube 17 so that one end is installed with the clamping post 4 and the clamping ring 3 on the other side, the square rod 10 is installed in the square slot 9 for positioning. After the installation is completed, it is convenient to separate and sand wash different types of fabrics and reduce fabric tangling and knotting.
