Description

Technical Field

[0001] This utility model relates to the technical field of cashmere combing machines, specifically a negative pressure dust removal device for cashmere combing machines. Background Technology

[0002] A cashmere carding machine is a device used to process cashmere fibers, primarily to comb and smooth them for subsequent processing and use. During operation, the cashmere raw material is fed into the machine via a feeding mechanism, then impurities are removed by a decoction and impurity removal mechanism, and finally, the combing is completed by a transmission and power mechanism. This design improves the removal of impurities from the raw fiber, contributing to higher quality finished wool fibers.

[0003] During the cashmere carding process, cashmere carding machines typically require a dust removal device to remove impurities from the cashmere. Existing dust removal devices usually absorb and filter floating impurities directly during the cashmere carding process. However, the impurities floating inside the cashmere carding machine contain a certain amount of cashmere. As the dust removal device absorbs the impurities, it also sucks away some cashmere, resulting in cashmere waste and reduced cashmere production. Furthermore, the impurities and cashmere sucked away by the dust removal device need to be further screened and processed, which increases the inconvenience for the staff. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cashmere flat comb negative pressure dust removal device, which solves the problem that traditional negative pressure dust removal devices suck up some cashmere along with impurities when processing cashmere. This prevents cashmere from being wasted during cashmere flat combing, increases cashmere production, and avoids the need for further screening of cashmere from impurities, reducing the trouble for workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cashmere flat comb negative pressure dust removal device, comprising a frame, a protective cover fixedly connected to the upper surface of the frame, and a dust collection component provided on the upper surface of the protective cover. An air suction hood is provided inside one end of the protective cover, and support plates are fixedly connected to the side surfaces of both ends of the air suction hood.

A through hole is opened on one side surface of the protective cover, and the through hole is aligned with the collecting roller.

[0006] Preferably, the drive assembly includes a mounting block, and support rods are fixedly connected to both sides of the mounting block. One end of the support rod is fixedly connected to the inner surface of the air intake hood. A drive shaft is rotatably connected to the lower surface of the mounting block, and fan blades are fixedly connected to the side surface of the drive shaft. A helical gear IV is fixedly connected to one end of the drive shaft.

[0007] Preferably, the transmission mechanism includes a rotating shaft II, which is rotatably connected to the inside of the air intake hood. One end of the rotating shaft II is fixedly connected to a helical gear V, and the other end of the rotating shaft II is fixedly connected to a helical gear III. One end of the helical gear III is provided with a transmission shaft, and the side surface of the transmission shaft is fixedly connected to the inner wall of the protective cover through a cross plate. Both ends of the transmission shaft are fixedly connected to helical gears II, and the helical gears II are respectively meshed with helical gear I and helical gear III.

A helical gear I 305 is fixedly connected to the other end of the rotating shaft I 304, and a transmission mechanism is provided on the side surface of the helical gear I 305. A drive component is connected to one end of the transmission mechanism. A through hole is opened on one side surface of the protective cover 2, and the through hole is aligned with the collecting roller 302.

[0019] As a technical optimization of this utility model, the drive assembly includes a mounting block 4, and support rods 401 are fixedly connected to both sides of the mounting block 4. One end of the support rods 401 is fixedly connected to the inner surface of the suction hood 3. A drive shaft 405 is rotatably connected to the lower surface of the mounting block 4, and a fan blade 402 is fixedly connected to the side surface of the drive shaft 405. A helical gear IV 403 is fixedly connected to one end of the drive shaft 405. The fan blade 402 on the side surface of the drive shaft 405 and the helical gear IV 403 at one end of the drive shaft 405 can drive the transmission assembly to rotate, thereby driving the collecting roller 302 to rotate and blocking the cashmere that is about to enter the suction hood 3.

[0020] As a technical optimization of this utility model, the transmission mechanism includes a rotating shaft II 309, which is rotatably connected to the inside of the air intake hood 3. One end of the rotating shaft II 309 is fixedly connected to a helical gear V 404, and the other end of the rotating shaft II 309 is fixedly connected to a helical gear III 308. One end of the helical gear III 308 is provided with a transmission shaft 306, and the side surface of the transmission shaft 306 is fixedly connected to the inner wall of the protective cover 2 through a horizontal plate. Both ends of the transmission shaft 306 are fixedly connected to helical gears II 307, and the helical gears II 307 are respectively meshed with helical gear I 305 and helical gear III 308.

[0021] As a technical optimization of this utility model, an air pump 202 is fixedly connected to the upper surface of the protective cover 2, and a pipe 203 is fixedly connected to one end of the air pump 202. One end of the pipe 203 passes through the protective cover 2 and is fixedly connected to the upper surface of the suction cover 3. A dust collection box 201 is fixedly connected to one side surface of the air pump 202. Through the cooperation of the air pump 202, the pipe 203 and the suction cover 3, the impurities floating inside the protective cover 2 can be extracted and collected by the dust collection box 201. A cover plate 2011 is installed at one end of the dust collection box 201, and filter holes 2012 are symmetrically opened on both sides of the dust collection box 201.

[0022] As a technical optimization of this utility model, a conveyor belt 101 is fixedly installed on the inner surface of one end of the frame 1, and a flat comb wheel 102 is rotatably installed on one end of the conveyor belt 101. A combing ring 103 is fixedly installed on the side surface of the flat comb wheel 102, and a conveyor roller 104 is rotatably connected to the inner surface of the other end of the frame 1.

[0023] In use, the cashmere to be combed is first placed on the upper surface of the conveyor belt 101 at one end of the frame 1. Simultaneously, the suction pump 202 on the upper surface of the protective cover 2 is started. The cashmere is then combed by the combing ring 103 on the side surface of the combing wheel 102 and then conveyed to the side surface of the conveyor roller 104 before being transported out. During the combing process by the combing ring 103, impurities and some cashmere inside the cashmere will float inside the protective cover 2. At this time, the suction pump 202 and pipe 203 will suck the impurities into the suction hood 3. Simultaneously, after the suction pump 202 is started, it drives the airflow, thereby driving the side surface of the fan blade 402. The drive shaft 405 rotates, and thus the drive shaft 405 will drive the rotating shaft II 309 and the transmission shaft 306 in the transmission mechanism to rotate through the helical gear IV 403. The transmission shaft 306 will drive the rotating shaft I 304 to rotate through the helical gear II 307. At this time, the rotating shaft I 304 drives the collecting roller 302 to rotate. During the rotation of the collecting roller 302, the hook 303 will wrap the floating cashmere around the side surface of the collecting roller 302, thereby blocking the cashmere and avoiding the waste of some cashmere. When the side surface of the collecting roller 302 is full of cashmere, the cashmere on the side surface of the collecting roller 302 can be taken out through the through hole on the side surface of the protective cover 2.
