Description

Technical Field

[0001] The utility model relates to the technical field of fabric processing equipment, in particular to an antistatic coating device for fabrics. Background Art

[0002] Sofa fabrics are the general or abbreviated terms for various main coverings used in the manufacture of sofas. With the development of technology and the improvement of people's living standards, sofa fabrics with antistatic functions have entered the market. Antistatic sofa fabrics are made of antistatic fabrics, which are fabrics processed by antistatic treatment.

[0003] At present, the working principle of the static coating device used in textile factories is a simple process of applying fabric antistatic agent to the surface of the fabric. Since when applying, a dipping brush is used to dip too much antistatic agent and then directly apply it to the surface of the fabric, this will cause direct waste of the excess antistatic agent.

[0004] Moreover, using a brush to apply the antistatic agent cannot evenly distribute the antistatic agent on the entire fabric. At the same time, simply applying on the surface cannot make the antistatic agent penetrate into the fabric interior, resulting in a significant reduction in the antistatic effect of the fabric after washing.

[0005] In addition, after the antistatic agent liquid is applied, it has a certain viscosity. If it is directly wound around the roller, a part of the antistatic agent will be adhered and removed, which will also reduce the antistatic effect of the fabric.

[0006] The above problems need to be improved and solved urgently. Content of the Utility Model

[0007] In order to overcome the deficiencies of the prior art, an antistatic coating device for fabrics is proposed.

[0008] The technical solution adopted by the utility model is: to provide an antistatic coating device for fabrics, including a frame, a driving device installed on the frame, a conveying device connected to the driving device, a coating and leveling device arranged on the conveying device, a negative pressure collection device arranged under the coating and leveling device, and a drying device arranged under the negative pressure collection device; the conveying device is provided with a fabric.

[0009] Preferably, the conveying device is a roller conveying system.

[0010] Preferably, the coating and leveling device includes a coating device and a leveling scraper arranged on one side of the coating device; the coating device and the leveling scraper are arranged above the fabric and installed on the frame.

[0011] Preferably, the leveling scraper includes a scraping plate, a liquid collecting groove opened on the scraping plate, and a scraping head arranged on one side of the liquid collecting groove.

[0012] Preferably, the negative pressure collection device includes a negative pressure device and a collection frame disposed on one side of the negative pressure device; the negative pressure device and the collection frame are installed on the frame.

[0013] Preferably, the collection frame is placed at the lower end of the squeegee and has a length greater than that of the squeegee.

[0014] Preferably, the negative pressure device includes a vacuum pump and a porous ceramic plate installed on the vacuum pump.

[0015] Advantages of the present utility model:

[0016] The present utility model adopts a uniform coating device to evenly attach the applied antistatic agent liquid to the surface of the fabric. At the same time, through the negative pressure collection device, the antistatic agent liquid penetrates into the fabric by negative pressure, and then the excess antistatic agent is collected. Finally, the fabric is preliminarily dried by a drying device and then wound around a roller. Specifically, the fabric is coated with the antistatic agent liquid through the coating device. When passing through the negative pressure device, under the action of negative pressure, the antistatic agent liquid penetrates into the fabric. Finally, under the action of the squeegee, the antistatic agent liquid is evenly attached to the surface of the fabric, and at the same time, the excess antistatic agent liquid is scraped off and collected into the collection frame. Finally, the fabric is preliminarily dried by a drying device and then wound around a roller. This process not only solves the problem of excessive waste of antistatic, but also solves the problem of poor antistatic effect caused by non-uniform coating of the antistatic agent and non-penetration of the antistatic agent into the fabric.

[0019] Figure 3 is Figure 1 a schematic structural diagram of the negative pressure device in Detailed Embodiments

[0020] The present utility model will be further described below with reference to specific drawings.

[0021] Specifically, an antistatic coating device for fabrics is provided, which includes a frame 10, a driving device 20 installed on the frame 10, a conveying device 30 connected to the driving device 20, a uniform coating device 40 disposed on the conveying device 30, a negative pressure collection device 50 disposed under the uniform coating device 40, and a drying device 60 disposed under the negative pressure collection device 50; a fabric 70 is provided on the conveying device 30.

[0022] AsFigure 1 As shown, the fabric 70 is conveyed by the conveying device 30 to be under the spreading device 40 and above the negative pressure collecting device 50. Under the spreading device 40, the antistatic agent liquid is evenly spread on the surface of the fabric. At the same time, under the action of the negative pressure collecting device 50, the antistatic agent liquid is adsorbed into the fabric, and the excess antistatic agent liquid is collected. Under the action of the conveying device 30, the fabric coated with the antistatic agent liquid is conveyed above the drying device 60 for preliminary drying, and finally wound around the roller of the conveying device 30.

[0023] The drying device 60 can be ultraviolet drying, and the temperature is 30 - 40 degrees Celsius.

[0024] Furthermore, the conveying device 30 is a roller conveying system.

[0025] Furthermore, the spreading device 40 includes a spreading device 41 and a leveling device 42 arranged on one side of the spreading device 41; the spreading device 41 and the leveling device 42 are arranged above the fabric 70 and installed on the frame 10.

[0026] Furthermore, the leveling device 42 includes a scraping plate 421, a liquid collecting groove 422 opened on the scraping plate 421, and a scraping head 423 arranged on one side of the liquid collecting groove 422.

[0027] Furthermore, the negative pressure collecting device 50 includes a negative pressure device 51 and a collecting frame 52 arranged on one side of the negative pressure device 51; the negative pressure device 51 and the collecting frame 52 are installed on the frame 10.

[0028] Furthermore, the collecting frame 52 is placed at the lower end of the scraping plate 421, and its length is greater than that of the scraping plate 421.

[0029] The length of the scraping plate 421 is greater than the width of the fabric 70.

[0030] As Figure 2 shown, when the fabric 70 passes through the leveling device 42, the scraping head 423 on the leveling device 42 abuts against the surface of the fabric 70 to level the antistatic agent liquid on the fabric 70. The excess antistatic agent liquid converges in the liquid collecting groove 422 and flows towards both ends of the liquid collecting groove 422. Since the length of the scraping plate 421 is greater than the width of the fabric 70, the antistatic agent liquid flows out from both ends of the scraping plate 421. Since the collecting frame 52 is placed at the lower end of the scraping plate 421 and its length is greater than that of the scraping plate 421, the flowing-out antistatic agent liquid flows into the collecting frame 52.

[0031] Furthermore, the negative pressure device 51 includes a vacuum pump 511 and a porous ceramic plate 512 installed on the vacuum pump 511.

[0032] As Figure 3As shown, in order to enhance the negative pressure performance of the negative pressure device 51, a porous ceramic plate 512 is installed on the vacuum pump 511, and the porous ceramic plate 512 itself has good adsorption capacity.

[0033] As Figures 1 to 3 shown, the negative pressure device 51 is arranged between the coating device 41 and the leveling device 42, and the collection frame 52 is arranged below the leveling device 42. In this way, after the coating device 41 applies the antistatic agent liquid to the fabric 70, the surface of the fabric 70 is relatively wet. When passing through the negative pressure device 51, it can better adsorb the antistatic agent liquid and make it penetrate into the interior of the fabric 70. Then, the leveling device 42 levels the antistatic agent liquid on the surface of the fabric 70 and collects the excess antistatic agent liquid into the collection frame 52.

[0034] For the present utility model, the specific operation is divided into the following steps: After the fabric 70 is output from the conveying device 30, the coating device 41 applies the antistatic agent liquid to the fabric 70. When the fabric 70 coated with the antistatic agent liquid passes above the negative pressure device 51, under the action of the adsorption force, the antistatic agent liquid penetrates into the interior of the fabric 70. When the fabric 70 with good penetration passes through the leveling device 42, under the action of the scraping plate 421, the antistatic agent liquid on the surface of the fabric 70 is leveled, and the excess antistatic agent liquid is guided to the collection frame 52 through the liquid collecting tank 422 for collection. Finally, when passing through the drying device 60, the fabric 70 is preliminarily dried and then wound around the roller of the conveying device 30.

[0035] In the above process, not only does the leveling device 42 and the collection frame 52 cooperate with each other to level the antistatic agent liquid on the fabric 70 and collect the excess antistatic agent liquid, but also the negative pressure device 51 is adopted to make the antistatic agent liquid penetrate into the interior of the fabric 70, solving the problems in the prior art that the antistatic agent liquid is only applied on the surface of the fabric 70 and the application is uneven, resulting in poor antistatic effect. At the same time, the drying device 60 is also adopted to preliminarily dry the fabric 70, solving the problem in the prior art that the directly coated fabric 70 is wound around the roller, resulting in partial removal of the antistatic agent and reduction of the antistatic effect of the fabric.
