Description

Technical Field

[0001] This invention relates to the field of fabric cleaning technology, and in particular to a fabric surface lint removal device. Background Technology

[0002] As textile machinery operates at increasingly higher speeds, coupled with the expanded use of cotton picking machines and metal needle cloth in cotton spinning, the concentration of dust in the air in spinning workshops has increased.

[0003] Most existing equipment uses both positive and negative air pressure to clean fabrics. Positive pressure involves blowing away fiber debris, dust, and other impurities from the fabric before it enters the next processing stage; however, these devices often lack a collection container. Negative pressure uses vacuum cleaners or similar devices to suck up the fiber debris, dust, and other impurities. To improve cleaning efficiency, this suction power is high, but the sucked-in fiber debris, dust, and other impurities easily clog the filter, resulting in a shorter filter cleaning cycle, higher energy consumption, and the inhaled air cannot be circulated. Summary of the Invention

[0004] To address the aforementioned problems, this invention discloses a fabric surface lint removal device, comprising a support frame, a dust collection mechanism positioned above the support frame, and an electrostatic adhesion roller disposed inside the support frame. The electrostatic adhesion roller includes a positive electrode sleeve and a negative electrode sleeve, with the positive electrode sleeve located inside the negative electrode sleeve. A protective sleeve, made of a high-resistance material, is fitted over the outer side of the negative electrode sleeve. A capacitor is formed between the positive and negative electrode sleeves. When a high voltage is applied, electrons accumulate on the negative electrode sleeve, and these electrons adhere to the fabric passing over the electrostatic adhesion roller, thus charging the fabric.

[0005] The dust collection mechanism includes a flat "O"-shaped outer shell. An air duct is located inside the shell, with an air inlet at the lower part of the duct. A bending plate is located above the air inlet, and several inclined electrode plates are located below the bending plate. These electrode plates are electrically connected to a positive electrode. The electrode plates are positively charged and interact with electrons on the fabric, drawing fabric fibers, dust, and other debris into the air inlet.

[0006] A cross-flow impeller is installed on one side of the upper end of the air duct, and a drive motor is fixedly connected to the side wall of the outer casing. The output end of the drive motor is fixedly connected to the cross-flow impeller, and a filter screen is installed at an angle inside the air duct. When the drive motor is started, the cross-flow impeller rotates and generates suction at the air inlet. At the same time, in conjunction with the action of the positive electrode plate, it sucks in fiber debris, dust, and other impurities.

[0007] Preferably, the support frame further includes two side plates, with a plurality of guide rollers disposed between the two side plates. The ends of the guide rollers and the electrostatic adhesion rollers are rotatably fitted onto the side plates. The side plates serve as support components, and transmission boxes and other components are also disposed on both sides of the side plates for driving the guide rollers and the electrostatic adhesion rollers to rotate.

[0008] Preferably, an electrostatic removal roller is disposed between the two side plates, and the electrostatic removal roller is grounded or electrically connected to a positive electrode. That is, the electrostatic removal roller conducts electrons away from the fabric.

[0009] Preferably, a connecting rod is fixedly connected between the lower parts of the two side plates, making the two side plates a single unit.

[0010] Preferably, a connector is fixedly connected to the lower part of the outer casing, and the lower part of the connector is fixedly connected to the side plate. The connector is L-shaped, realizing the connection between the support frame and the dust collection box.

[0011] Preferably, a storage box is provided below the filter screen. Debris trapped by the filter screen falls into the storage box for convenient centralized processing.

[0012] Preferably, a first handle is fixedly connected to one side of the filter screen, and a second handle is fixedly connected to one side of the storage box. The first handle and the second handle are used to remove the filter screen and the storage box, respectively.

[0013] Preferably, a pressure relief port is provided on one side of the upper end of the housing, and the pressure relief port is located between the cross-flow impeller and the filter screen. This allows the gas drawn into the air duct to be discharged.

[0014] The beneficial effects of this invention are as follows: 1. It is equipped with an electrostatic adhesion roller to charge the fabric. With the help of the electrode plate, the electric field generated when the fabric passes through the air inlet will adsorb the impurities on the fabric. In addition, the cross-flow impeller allows the gas to circulate in the air duct, and the setting of the air inlet bending plate makes it easier for impurities on the fabric to be sucked into the air inlet.

[0015] 2. With the help of an electrostatic field, the speed of the cross-flow impeller does not need to be too high. In addition, the air circulates in the air duct, which can utilize some of the kinetic energy of the air flow. Relatively speaking, the energy consumption of the dust collection mechanism is relatively low.

[0016] 3. At relatively low wind speeds, and with the filter screen tilted to increase the filtration area, the cleaning cycle of the filter screen is greatly extended. Attached Figure Description

[0019] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] like Figures 1 to 6 As shown, a fabric lint removal device includes a support frame 3, a dust collection mechanism 1 above the support frame 3, and an electrostatic adhesion roller 33 inside the support frame 3. Fabric 2 passes through the electrostatic adhesion roller 33, causing the fabric 2 to carry electrons. The electrostatic adhesion roller 33 includes a positive electrode sleeve 331 and a negative electrode sleeve 333, which together form a capacitor. The positive electrode sleeve 331 is located inside the negative electrode sleeve 333. A protective sleeve 332 is fitted over the outside of the negative electrode sleeve 333 to prevent direct exposure of the negative electrode sleeve 333. The protective sleeve 332 enhances safety by being made of a high-resistance material, meaning it is not completely insulated, ensuring that electrons can reach the surface of the protective sleeve 332. For safety, the resistance value of the protective sleeve 332 is not less than 10 ohms. 6 Ω, due to the different fabric materials, protective covers of different materials can be replaced according to the needs of production efficiency 332.

[0021] The vacuuming mechanism 1 includes a flat "O"-shaped outer shell 11. An air duct 110 is located inside the outer shell 11; the air duct 110 is also O-shaped to maximize the circulation of internal air, thereby reducing kinetic energy loss and energy consumption. An air inlet 113 is located at the lower part of the air duct 110, and a bending plate 112 is located at the upper part of the air inlet 113. When air circulates in the air duct 110, the cross-section at the air inlet 113 is adjusted due to the bending plate 112. The reduced area increases the wind speed through the air inlet 113, which helps to improve the Bernoulli principle effect at the air inlet 113, that is, the suction force of the air inlet 113 is greater. Several inclined electrode plates 111 are arranged below the bending plate 112. The electrode plates 111 are electrically connected to the positive electrode sleeve 331. Since the fabric 2 carries electrons and the electrode plates 111 carry positive charges, together with the suction force at the air inlet 113, the fiber debris, dust and other debris on the fabric 2 are sucked away, thereby achieving the cleaning effect.

[0022] A cross-flow impeller 19 is provided on one side of the upper end of the air duct 110. A drive motor 14 is fixedly connected to the side wall of the outer casing 11. The output end of the drive motor 14 is fixedly connected to the cross-flow impeller 19. When the drive motor 14 is started, the cross-flow impeller 19 rotates, causing the gas in the air duct 110 to flow. A filter screen 15 is inclinedly arranged inside the air duct 110. The filter screen 15 is used to trap the sucked-in fiber debris, dust, etc. At the same time, the purpose of the inclined arrangement of the filter screen 15 is to greatly increase the filtration area and extend the cleaning cycle of the filter screen 15.

[0023] The support frame 3 also includes two side plates 34, which are the support components of the device. Several guide rollers 31 are arranged between the two side plates 34. The ends of the guide rollers 31 and the electrostatic adhesion rollers 33 are rotatably fitted on the side plates 34.

[0024] An electrostatic removal roller 35 is provided between the two side plates 34. The electrostatic removal roller 35 is grounded or electrically connected to the positive electrode sleeve 331 to remove electrons from the fabric 2, that is, to remove static electricity from the fabric 2.

[0025] A connecting rod 32 is fixedly connected between the two side plates 34 at the bottom, making the two side plates 34 a single structure.

[0026] A connector 13 is fixedly connected to the lower part of the outer casing 11. The connector 13 is L-shaped and the lower part of the connector 13 is fixedly connected to the side plate 34. The vacuuming mechanism 1 and the support frame 3 are integrated into one unit through the connector 13.

[0027] Below the filter screen 15 is a storage box 17, which collects the fiber debris, dust and other particles trapped by the filter screen 15, making it easy to clean regularly.

[0028] A first handle 18 is fixedly connected to one side of the filter screen 15. The filter screen 15 is removed from the inside of the outer casing 11 by means of the first handle 18. A second handle 16 is fixedly connected to one side of the storage box 17. The storage box 17 is removed from the outer casing 11 by means of the second handle 16.

[0029] A pressure relief port 12 is provided on one side of the upper end of the outer casing 11. The pressure relief port 12 is located between the cross-flow impeller 19 and the filter screen 15. That is, gas is drawn in at the air inlet 113, while the pressure relief port 12 sends out excess gas in the air duct 110.
