Description

Technical Field

[0001] This invention belongs to the field of textile technology, specifically relating to a combing machine and combing method for improving the quality of wool web. Background Technology

[0002] Carding machines are widely used as key production equipment in cashmere textile manufacturing enterprises. The condition of the wool web in a carding machine directly affects the quality of the output sliver, and consequently, the quality of the yarn. In production applications, the first-pass carding area of ​​the Japanese Kyowa carding machine is equipped with a pressing roller device. The function of the pressing roller device is to remove straw and impurities from the wool web. However, the cashmere raw materials used by cashmere manufacturers today are dehaired cashmere that has already been carded and is free of straw and impurities. During equipment use, when the moisture regain of the cashmere and the temperature and humidity of the workshop fluctuate, the pressing roller is prone to tangling and wrapping, causing damage to the wool web and resulting in poor sliver quality from the carding machine. Moreover, during the lifting operation, the pressing roller area is also prone to pinching hands, posing a safety hazard. Summary of the Invention

[0003] The purpose of this invention is to provide a combing machine and combing method to improve the quality of the wool web, which solves the problem of wool web damage caused by the pressing roller easily getting tangled with wool during the production process of the combing machine, thus affecting the output quality of the combing machine.

[0004] To achieve the above objectives, the technical solution used in this invention is as follows: A carding machine for improving the quality of wool web includes: a frame, a doffer gear, a cylinder pulley, a transport curtain pulley, and a lifting cord gear. The frame has support feet on its sides, each consisting of a shaft hole plate, a fixing plate, and a connecting post. Two pairs of fixing plates and connecting posts are located on opposite sides of the shaft hole plate. The fixing plate has fixing holes, and one end of the connecting post connects to the fixing plate, while the other end connects to the shaft hole plate. The shaft hole plate has a first shaft hole, a second shaft hole, a third shaft hole, and a fourth shaft hole. The first and second shaft holes are elongated holes extending perpendicularly to each other. The third shaft hole is a round hole, and the fourth shaft hole is an arc-shaped elongated hole, the center of which coincides with the center of the third shaft hole. The first shaft hole is used to install the shaft of the doffer gear, the second shaft hole is used to install the shaft of the cylinder pulley, the third shaft hole is used to install the shaft of the transport curtain pulley, and the fourth shaft hole is used to install the shaft of the lifting cord gear.

[0005] Furthermore, the two fixing plates are located on the same side of the shaft hole plate, the shaft hole plate and the fixing plates are parallel to each other, and the connecting columns are perpendicular to the shaft hole plate and the fixing plates respectively.

[0006] Furthermore, the fixing plate includes: a first fixing plate and a second fixing plate, which are located on both sides of the shaft hole plate. The first fixing plate has one fixing hole and the second fixing plate has two fixing holes, which are elongated holes. The connecting column is a hollow columnar body, including: a first connecting column and a second connecting column. The first connecting column is connected to the first fixing plate and the shaft hole plate at both ends, and the second connecting column is connected to the second fixing plate and the shaft hole plate at both ends.

[0007] Furthermore, one end of the doffer gear's shaft is installed in the first shaft hole, and the other end is installed in the shaft hole of the other side frame; one end of the cylinder pulley's shaft is installed in the second shaft hole, and the other end is installed in the shaft hole of the other side frame; one end of the conveyor curtain pulley's shaft is installed in the third shaft hole, and the other end is installed in the shaft hole of the other side frame; one end of the lifting curtain gear's shaft is installed in the fourth shaft hole, and the other end is installed in the shaft hole of the other side frame.

[0008] Furthermore, the shafts of the doffer gear, cylinder pulley, transport curtain pulley, and lifting curtain gear are respectively mounted on the support feet of the two side frames.

[0009] Combing methods to improve the quality of the wool web include: Remove the straw pressing roller device located between the doffer and the transport curtain in the first combing area, and install a support foot in the empty position on the side of the cylinder belt. Fix the support foot to the frame with bolts. The shaft for installing the doffer gear is installed in the first shaft hole, the shaft for the cylinder pulley is installed in the second shaft hole, the shaft for the conveyor curtain pulley is installed in the third shaft hole, and the shaft for the lifting curtain gear is installed in the fourth shaft hole, thereby realizing the transmission between the cylinder, the doffer, and the conveyor curtain. The wool web, after being combed in the first combing zone, is stripped off by the doffer cutter and transferred to the lifting screen via the transport curtain before entering the second combing zone.

[0010] Preferably, a carding machine is used to produce 11-32 count pure cashmere yarn and cashmere blended yarn.

[0011] The technical effects of this invention include: This invention solves the problem of damaged wool web caused by the pressing rollers easily getting tangled and wrapped around wool during the production process of the combing machine (Kyowa, Japan), which affects the output quality of the combing machine. It also eliminates the safety hazard of workers accidentally squeezing their hands during the lifting operation.

[0012] This invention not only allows the wool web cut by the first doffer to be directly transferred to the transport curtain in good condition, improving the output quality of the carding machine, but also eliminates the safety hazard of hand squeezing accidents at the straw pressing roller part during the operation of the lifting head.

[0013] This invention has a simple structure, is easy to assemble, and requires fewer parts. Through production practice, it has improved the yarn quality in the combing process while ensuring the quality of the wool web, and has avoided safety accidents such as hand squeezing. It has broad application and promotion prospects. Attached Figure Description
