Description

Technical Field

[0001] This utility model belongs to the field of printing and dyeing equipment technology, specifically relating to a high-efficiency pretreatment device for polyester fabrics. Background Technology

[0002] During the production of polyester fabrics, a lot of fuzz is generated on the surface of the fabric. In order to obtain a smoother fabric, it is necessary to remove the fuzz through singeing. After the singeing is completed, a dust collection device is needed to remove the fuzz and debris remaining on the surface of the fabric. However, the existing dust collection device cannot completely remove the fuzz from the fabric when vacuuming both sides of the fabric. As a result, the fabric with fuzz remaining is prone to causing numerous irregular small white spots on the fabric surface or irregular waxy white streaks on the warp yarns during the subsequent printing and dyeing process, which reduces the printing and dyeing quality of the fabric. Summary of the Invention

[0003] The present invention aims to solve the technical problems existing in the prior art and provide a high-efficiency pretreatment device for polyester fabrics.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a high-efficiency pretreatment device for polyester fabric, including a tube shell, the tube shell being a hollow structure, with inlet and outlet holes for fabric at both the top and bottom of the tube shell, and rubber flaps on both the front and rear sides of the inlet and outlet holes on the upper side, the rubber flaps being rotatably connected to the front and rear ends of the inlet and outlet holes, a support spring for supporting the rubber flaps being provided inside the tube shell, the bottoms of the two rubber flaps abutting against each other, and a symmetrical insert plate being provided at the lower middle position of the tube shell, the insert plate being slidably connected to the tube shell, the inner of the two insert plates... Each end is provided with a sealing rubber plate, and the inner ends of the two sealing rubber plates abut against each other. Two sets of brush assemblies are symmetrically arranged on the shell of the two sealing rubber plates. The brush assembly includes two rotating handles located at the left and right ends of the shell, and the two rotating handles extend into the shell. A brush plate is connected between the two rotating handles. The inner ends of the two rotating handles are rotatably connected to the brush plate. Two pressure rollers are symmetrically arranged inside the shell on the lower side of the two insert plates. The two pressure rollers are rotatably connected inside the shell. Multiple scrapers are arranged in a ring array along the axis on the surface of the pressure rollers. A duct is connected to the shell on both the upper and lower sides of the insert plate.

[0005] Preferably, the brush plate has several bristles at the end away from the rotating handle.

[0006] Preferably, the surface of the pressure roller between two adjacent scrapers is covered with felt.

[0007] Preferably, the height of the scraper is greater than the thickness of the felt.

[0008] The beneficial effects of this invention are as follows: By setting up a brush assembly, the brush plate in the brush assembly performs preliminary brushing on both surfaces of the fabric, and the dust and lint brushed off are sucked away through the air duct. Then, the two surfaces of the fabric are quickly brushed by the pressure roller. The scraper set on the surface of the pressure roller can deeply scrape the surface of the fabric, scraping off the sintered particles that are tightly attached to the surface of the fabric after lint removal, and sucking them away through the air duct. The scraper set on the surface of the pressure roller can efficiently remove the sintered particles remaining on the surface of the fabric, and the brush plate can remove dust and lint from the surface of the fabric, which can further improve the cleanliness of the fabric surface and avoid affecting the printing and dyeing quality of the fabric.

[0012] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0013] Example: A high-efficiency pretreatment device for polyester fabrics, such as Figures 1-2 As shown, the device includes a hollow tube shell 1. Both the top and bottom of the tube shell 1 have inlet / outlet holes 2. Rubber flaps 3 are provided on both the front and rear sides of the upper inlet / outlet holes 2, and the rubber flaps 3 are rotatably connected to the front and rear ends of the inlet / outlet holes 2. A support spring 4 is provided inside the tube shell 1 to support the rubber flaps 3. The bottoms of the two rubber flaps 3 abut against each other. A symmetrical insert plate 5 is provided at the lower center of the tube shell 1, and the insert plate 5 is slidably connected to the tube shell 1. A sealing rubber plate 6 is provided at the inner end of each of the two insert plates 5. The inner ends abut against each other. Two sets of brush assemblies are symmetrically arranged on the shell of the two sealing rubber plates 6. The brush assembly includes two rotating handles 7 located at the left and right ends of the tube shell 1. The two rotating handles 7 extend into the inside of the shell. A brush plate 8 is connected between the two rotating handles 7. The inner ends of the two rotating handles are rotatably connected to the brush plate 8. Two pressure rollers 9 are symmetrically arranged inside the tube shell 1 on the lower side of the two insert plates 5. The two pressure rollers 9 are rotatably connected inside the tube shell 1. Multiple scrapers 10 are arranged in a ring array along the axis on the surface of the pressure rollers 9. A duct 11 is connected to the tube shell 1 on both the upper and lower sides of the insert plate 5.

[0014] The brush plate 8 is provided with a number of bristles 12 at the end away from the rotating handle 7; the surface of the pressure roller 9 between two adjacent scrapers 10 is covered with felt 13; the height of the scraper 10 is higher than the thickness of the felt 13.

[0015] The principle of this utility model: Two air ducts 11 need to be connected to a dust collection device, and two pressure rollers 9 are connected to a motor for driving. When in use, the cloth enters from the inlet and outlet of the top of the tube shell 1 and exits from the inlet and outlet of the bottom. The cloth passes between two rubber flaps 3, brush plates 8, two sealing rubber plates 6 and two brush rollers. The rubber flaps 3 can prevent the internal dust from leaking out, and the sealing rubber plates 6 can prevent the dust and impurities in the two parts from communicating with each other. The cloth passes between the brush plates 8 and the brush bristles 12 clean the surface of the cloth. The brushed impurities and dust are discharged through the air ducts 11. The two pressure rollers 9 are attached to the surface of the cloth and rotate quickly. The scraper touches the surface of the cloth to achieve a scraping effect. The scraped sintered particles are also discharged by the air ducts 11.

[0016] There is a gap between the inner ends of the two sealing plates 6 for the fabric to pass through, and they will not directly contact the fabric.

[0017] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
