Description

Technical Field

[0001] The invention relates to the technical field of fabric cleaning, and in particular to a device for removing fluff from the surface of fabric. Background Art

[0002] Certain processes in cotton, wool, linen and silk spinning factories, such as cotton blending, wool selection, soft linen, loosening and combing, will discharge a lot of dust. Some spinning equipment, such as blow room machinery, uses airflow to transport and condense fibers or remove waste during processing, which will also discharge a lot of dusty air. If textile factories do not take air purification measures, a large amount of dusty air will spread widely, seriously polluting the workshop and the surrounding environment, directly endangering the health of employees and affecting product quality. The operating speed of textile machinery is getting higher and higher, and the expanded use of machine picking and metal needle clothing in cotton spinning has increased the dust concentration in the air of the spinning workshop. The world's industrial countries have increasingly stringent requirements on the air quality of textile workshops. Therefore, dust removal in textile mills has become a prominent issue in the design of new factories and the technical transformation of existing factories.

[0003] Most of the existing equipment uses positive and negative wind pressure to clean fabrics. In the case of positive pressure, fiber debris, dust and other debris on the fabric are blown away by wind before the fabric is sent to the next treatment process, but most of the devices are not equipped with a collection container. In the case of negative pressure, fiber debris, dust and other debris on the fabric are sucked away by equipment such as vacuum cleaners. In order to improve the cleaning effect, the suction force is relatively large, and the fiber debris, dust and other debris sucked in are easy to clog the filter. The filter cleaning cycle is short, the energy consumption is high, and the sucked gas cannot be circulated. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a device for removing fluff from the surface of fabrics, including a support frame, a dust suction mechanism is arranged above the support frame, an electrostatic adhesion roller is arranged inside the support frame, the electrostatic adhesion roller includes a positive electrode sleeve and a negative electrode sleeve, and the positive electrode sleeve is located inside the negative electrode sleeve, and a protective sleeve is sleeved on the outer side of the negative electrode sleeve, and the protective sleeve is located on a high resistance material. A capacitor is formed between the positive electrode sleeve and the negative electrode sleeve, and high voltage electricity is connected. Electrons gather on the negative electrode sleeve, and electrons are attached to the fabric bypassing the electrostatic adhesion roller, so that the fabric is charged.

[0005] The dust collecting mechanism comprises a flat "O"-shaped shell, an air duct is arranged inside the shell, an air inlet is arranged at the lower part of the air duct, a bending plate is arranged at the upper part of the air inlet, and a plurality of electrode plates are arranged obliquely below the bending plate, and the electrode plates are electrically connected to the positive electrode sleeve. The electrode plates are positively charged and act on the upper electrons of the fabric, and the fiber debris, dust and other debris of the fabric are sucked into the air inlet.

[0006] A crossflow impeller is arranged on one side of the upper end of the air duct, a driving motor is fixedly connected to the side wall of the housing, an output end of the driving motor is fixedly connected to the crossflow impeller, and a filter is obliquely arranged inside the air duct. When the driving motor is started, the crossflow impeller rotates and generates suction at the air inlet, and at the same time cooperates with the positive plate to suck in fiber debris, dust and other debris.

[0007] Preferably, the support frame further comprises two side plates, a plurality of guide rollers are arranged between the two side plates, and the ends of the guide rollers and the electrostatic adhesion rollers are rotatably engaged on the side plates. The side plates are support members, and transmission boxes and other components are also arranged on both sides of the side plates for driving the guide rollers and the electrostatic adhesion rollers to rotate.

[0008] Preferably, a static electricity removal roller is arranged between the two side plates, and the static electricity removal roller is grounded or electrically connected to the positive electrode sleeve, that is, the static electricity removal roller conducts away the electrons of the fabric.

[0009] Preferably, a connecting rod is fixedly connected at the lower part between the two side panels, so that the two side panels become a whole.

[0010] Preferably, a connecting piece is fixedly connected to the lower part of the shell, and the lower part of the connecting piece is fixedly connected to the side plate. The connecting piece is L-shaped to achieve the connection between the support frame and the dust box.

[0011] Preferably, a storage box is provided below the filter screen, and the debris intercepted by the filter screen falls into the storage box, which is convenient for 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 to discharge the inhaled gas in the air duct.

[0014] The beneficial effects of the present invention are as follows: 1. An electrostatic adhesion roller is provided to charge the fabric. When the fabric passes through the air inlet, the electric field generated will adsorb the debris on the fabric. In addition, the cross-flow impeller makes the gas circulate in the air duct, and the setting of the air inlet bending plate makes it easier for the debris on the fabric to be sucked into the air inlet.

[0015] 2. With the help of the 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 part of the kinetic energy of the gas flow. Relatively speaking, the energy consumption of the dust collection mechanism is relatively low.

[0016] 3. At relatively low wind speeds, the filter is tilted to increase the filter area, greatly extending the filter cleaning cycle. BRIEF DESCRIPTION OF THE DRAWINGS
