Description

Technical Field

[0001] The present application belongs to the field of carding fiber web production, and in particular to a carding machine web coagulation device. Background Art

[0002] Fiber web carding machine, also known as carding machine, is a very important equipment in textile technology. Its main function is to loosen the fibers initially, further loosen the mixed fiber pieces and bundles, and comb them into single fibers, so as to reduce fiber damage and lint or neps.

[0003] The existing carding machine has doffer, first condensation, second condensation, stripping roller, cleaning roller and net curtain after the main cylinder; the fiber web is transferred to the condensation through the doffer, and the fiber web is condensed by the speed difference of the two condensations, and then transferred to the net curtain through the stripping roller; when producing thin weight, the fiber web is easy to entangle the condensation and stripping rollers; when producing thick weight, the fiber web is not easy to transfer, so the normal production of single-layer fiber web is 20g / m 2 About 40g / m2 for two layers 2 , the limitations are high and the specifications of the products produced are relatively limited.

[0004] Therefore, a new carding machine web-condensing device is needed to solve the above problems. Summary of the invention

[0005] In order to address the deficiencies of the prior art, the present application provides a carding machine web coagulation device, which simplifies the complexity of the equipment and facilitates transfer and coagulation. Fiber webs of different specifications can be produced by adjusting the speed of conveying the web curtain.

[0006] The technical effects to be achieved by this application are achieved through the following solutions:

[0007] According to the first aspect of the present application, there is provided a carding machine web coagulation device, comprising a main cylinder and a plurality of doffers, wherein the doffers are arranged at the rear end of the main cylinder and are arranged side by side up and down, and a conveying net curtain is provided under the doffers, and fibers are transferred between the doffers and the conveying net curtain by a blower mechanism, and an adsorption mechanism is provided in the conveying net curtain, and the adsorption mechanism is used to adsorb fibers to the surface of the conveying net curtain.

[0008] Through this solution, the blower mechanism blows the fibers on the doffer onto the conveying mesh curtain. The adsorption mechanism on the conveying mesh curtain can adsorb the fibers to achieve coagulation. The weight of the fiber web can be adjusted by adjusting the speed of the conveying mesh curtain. Not only is the equipment simple, but the production is also convenient.

[0009] Preferably, the conveying mesh curtain comprises an air-permeable mesh curtain and a plurality of conveying rollers, and the air-permeable mesh curtain surrounds the conveying rollers to form a conveying loop.

[0010] Through this solution, the breathable mesh curtain can allow air flow to pass through, so that the fibers are adsorbed to the surface of the breathable mesh curtain under the action of the adsorption mechanism.

[0011] Preferably, the adsorption mechanism is disposed below the breathable mesh curtain and is arranged in close contact with the breathable mesh curtain.

[0012] Preferably, the adsorption mechanism comprises a negative pressure box and a negative pressure pump, wherein the negative pressure pump is used to provide negative pressure for the negative pressure box, and the top of the negative pressure box is open.

[0013] Through this solution, the opening at the top of the negative pressure box can inhale a large amount of air, thereby achieving adsorption through the breathable mesh curtain.

[0014] Preferably, the top opening of the negative pressure box is provided with a mesh plate.

[0015] Through this solution, the mesh plate plays a supporting role and improves the flatness of the surface of the breathable mesh curtain, thereby ensuring the cohesion effect of the fiber mesh and avoiding depression under the action of negative pressure and affecting product quality.

[0016] Preferably, a first air uniforming plate is provided in the negative pressure box, a plurality of first ventilation holes are evenly provided on the first air uniforming plate, and the negative pressure pump is connected to the negative pressure box below the first air uniforming plate.

[0017] Through this solution, the first air uniformity plate can ensure the pressure balance in the negative pressure box, so that the adsorption force of the breathable mesh curtain is consistent at all locations, ensuring the uniformity of the condensation process and improving product quality.

[0018] Preferably, the negative pressure box comprises a plurality of negative pressure chambers, each of which is connected to a pressure regulating valve, and the pressure regulating valve is used to adjust the pressure of the negative pressure chamber.

[0019] Through this solution, the pressure of each negative pressure chamber can be adjusted individually to meet the requirements of different production processes. For example, the condensed fiber web can be easily peeled off during transportation.

[0020] Preferably, the width of the air permeable portion of the air permeable mesh curtain is consistent with the width of the mesh plate, and sealing strips are provided on both sides of the air permeable portion.

[0021] Through this solution, the sealing strip can prevent air leakage on both sides of the breathable mesh curtain from affecting the adsorption effect, thereby ensuring the effectiveness of condensation.

[0022] Preferably, the blowing mechanism comprises a bellows and a blower, the bottom opening of the bellows faces the doffer and the conveying mesh curtain, a second air uniforming plate is arranged at the bottom opening of the bellows, and a plurality of second ventilation holes are evenly arranged on the second air uniforming plate.

[0023] Through this solution, the second wind uniformity plate can ensure that the wind blown into the bellows is more uniform, ensure that the air volume blown out from the opening is consistent, and ensure that the fibers peeled off the doffer are evenly condensed on the breathable mesh curtain.

[0024] Preferably, ends of several of the conveying mesh curtains are stacked.

[0025] Through this solution, it is convenient to stack the condensed fiber web to form fiber webs of different layers.

[0026] According to one embodiment of the present application, the beneficial effect of using the web coagulation device of the carding machine is that the first coagulation, second coagulation, stripping roller and cleaning roller of the conventional carding machine are eliminated, the net curtain is changed to an anti-static breathable net curtain, and an adsorption mechanism for under-net suction is added underneath, and the variable frequency fan can adjust the fan speed by adjusting the frequency of the inverter through electrical control, so that the suction of the negative pressure chamber in each zone can be adjusted separately; there is a certain distance (2-10mm) between the doffer and the breathable net curtain, and the fiber web on the doffer reaches the net curtain by being stripped onto the breathable net curtain through under-net suction and coagulated on the breathable net curtain, and the coagulation degree and gram weight of the fiber web are adjusted by adjusting the speed difference between the breathable net curtain and the doffer; the residual fibers on the doffer are blown down by the hair dryer and adsorbed onto the breathable net curtain, which can achieve a larger longitudinal and transverse strength ratio and a wide range of gram weight fiber web production.
