A flame-retardant finishing device for flame-retardant and antistatic fabrics

Abstract

This utility model provides a flame-retardant finishing device for flame-retardant and antistatic fabrics, belonging to the technical field of flame-retardant finishing equipment. It addresses the problem that the flame retardant is difficult to fully penetrate the inner fiber layer of the fabric due to multiple factors such as fabric structure, solution surface tension, and immersion time during the solution penetration process. The device includes: an inner adjusting frame; two sets of opposing extrusion scrapers fixed to the outer wall of the inner adjusting frame; an adjusting screw threaded onto the outer adjusting block; and the adjusting screw being a bidirectional threaded rod rotatably connected to a positioning groove. The device employs a combination of vibration and extrusion, effectively promoting the penetration of the flame-retardant material into the fabric. A telescopic cylinder moves the inner adjusting frame up and down, causing the fabric to vibrate within the flame-retardant material. Simultaneously, the extrusion scrapers further extrude the flame-retardant material into the fabric through a scraping motion, ensuring sufficient contact between the flame-retardant material and the fabric fibers, thus improving the overall flame-retardant performance of the fabric.

Description

Technical Field

[0001] This utility model belongs to the technical field of flame retardant finishing equipment, and more specifically, it relates to a flame retardant finishing equipment for flame retardant and antistatic fabrics. Background Technology

[0002] In today's industrial production and daily life, flame-retardant and antistatic fabrics play a crucial role in many fields due to their excellent safety. At the same time, with the advancement of technology and the continuous improvement of market demand, the performance requirements for flame-retardant and antistatic fabrics are becoming increasingly stringent. Not only are the fabrics required to have more durable and efficient flame-retardant and antistatic properties, but it is also expected that the finishing equipment can improve production efficiency while reducing energy consumption and production costs. However, existing flame-retardant finishing equipment is difficult to meet these new demands, so a flame-retardant finishing equipment is needed.

[0003] Based on existing technologies, the impregnation method is the mainstream process for applying flame retardant materials. This process involves completely immersing the fabric in a flame retardant solution and using the direct contact between the solution and the fabric to achieve the adhesion of the flame retardant material. However, the solution penetration process is constrained by multiple factors such as the fabric structure, the surface tension of the solution, and the immersion time, making it difficult for the flame retardant to fully penetrate into the internal fiber layer of the fabric. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, this utility model relates to a flame-retardant finishing device for flame-retardant and antistatic fabrics, so as to solve the problem that the flame retardant is difficult to fully penetrate into the inner fiber layer of the fabric due to multiple factors such as the fabric structure, solution surface tension and immersion time during the solution penetration process.

[0012] Preferably, the four sets of external adjustment blocks are slidably connected in the two sets of position adjustment grooves, and each of the four sets of external adjustment blocks has a threaded through hole.

[0013] The flame-retardant finishing equipment for flame-retardant and antistatic fabrics proposed in this utility model has the following beneficial effects:

[0014] 1. The method of combining vibration and compression is adopted to effectively promote the penetration of flame retardant materials into the fabric. The telescopic cylinder drives the inner adjustment frame to move up and down, causing the fabric to vibrate in the flame retardant material. This breaks the limitation of traditional impregnation methods where flame retardant materials are difficult to penetrate into the inner layer of the fabric. At the same time, the compression scraper further compresses the flame retardant material into the fabric through a scraping method, so that the flame retardant material can fully contact the fabric fibers and improve the overall flame retardant performance of the fabric.

[0015] 2. By adjusting the screw and the external adjusting block, the distance between the fixed roller frames can be easily adjusted, thereby adjusting the relative position of the inner clamping rollers. This adjustment function allows the equipment to flexibly constrain the fabric according to its thickness, width and material characteristics, avoiding the overlap of the fabric during vibration and ensuring the flatness and uniformity of the fabric during processing.

[0031] The specific usage and function of this embodiment are as follows:

[0032] In this invention, during use, four sets of top fixing frames 301 are inserted into the top of the material loading trough 1, and then the locking blocks 302 are used to lock the top fixing frames 301 to ensure that the top fixing frames 301 are stably fixed at the top of the material loading trough 1, thereby ensuring the overall stability of the telescopic cylinder 306. The fabric to be flame-retardant treated is introduced from one side of the material loading trough 1 and conveyed by the auxiliary rollers 202. The auxiliary rollers 202 help the fabric move smoothly in the material loading trough 1, ensuring that the fabric smoothly enters the processing area of ​​the inner adjusting frame 401. When installing the fabric, it is necessary to ensure that the fabric is flat and avoid wrinkles or twists. According to the thickness, width and material characteristics of the fabric, the spacing between the fixing roller frames 501 is adjusted. Specifically, the adjusting screw 504 in the adjusting groove 402 is rotated. Since the adjusting screw 504 is a bidirectional threaded rod, when rotated, the relative position of the outer adjusting block 503 is adjusted through the bidirectional thread, thereby driving the fixing roller frames 501 and The inner clamping roller 502 moves to adjust the spacing. After adjusting to a suitable spacing, it ensures that the fabric can be stably constrained by the inner clamping roller 502, avoiding overlap during subsequent processing. The telescopic cylinder 306 is activated, and the telescopic rod of the telescopic cylinder 306 drives the top plate 403 to move up and down, thereby allowing the inner adjusting frame 401 to rise and fall within the inner groove 102. The up and down movement of the inner adjusting frame 401 causes the fabric constrained by the inner clamping roller 502 to vibrate and adjust within the flame retardant material. During the vibration, the flame retardant material can more easily penetrate into the fabric, achieving full impregnation treatment. The extrusion scraper 404 on the outer wall of the inner adjusting frame 401 moves with the inner adjusting frame 401, further squeezing the flame retardant material into the fabric through a scraping method, enhancing the impregnation effect between the fabric and the flame retardant material. After the fabric has completed the flame retardant finishing treatment, the telescopic cylinder 306 is stopped, causing the inner adjusting frame 401 to stop moving.
