Description

Technical Field

[0001] The utility model relates to the technical field of carding machines, in particular to a feeding structure of a carding machine with high feeding efficiency. Background Art

[0002] A cotton carding machine is a textile machine used to process cotton fibers and chemical fibers. The cotton carding machine uses a flat or roller-type cotton carding machine to comb small cotton bundles into single fiber state with the help of needle movement, further remove impurities and unspinnable short fibers, make the fibers parallel and straight, and finally make them into cotton strips and put them into strip cans.

[0003] Before the carding machine is used, the cotton yarn needs to be fed through the feeding device. In the existing technology, most feeding devices usually use two clamping rollers to clamp the cotton yarn when in use. After the two clamping rollers are used for a long time, a large amount of cotton yarn will be adhered to the outer wall. When there are too many cotton yarns adhered to the outer wall, it is easy to affect the clamping effect of the cotton yarn, thereby reducing the feeding efficiency of the carding machine and the practicality is insufficient. Therefore, it is necessary to redesign a carding machine feeding structure with high feeding efficiency to address the above problems. Utility Model Content

[0012] Beneficial effects of the utility model:

[0013] 1.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 , a feeding structure of a cotton carding machine with high feeding efficiency, including a transport device 1, two support plates 2 are fixedly installed on the upper end surface of the transport device 1, and the inner walls of the support plates 2 are fixedly connected to the upper hopper 4 through a connecting mechanism, and the connecting mechanism includes a connecting block 3 fixedly installed on the inner wall of the support plate 2, and the end of the connecting block 3 is fixedly connected to the outer wall of the upper hopper 4. Two clamping rollers 5 are rotatably installed between the two support plates 2, and gears 6 are fixedly installed on the outer walls of the rotating shafts of the two clamping rollers 5. The two gears 6 are engaged with each other. A motor 7 connected to one of the clamping rollers 5 is fixedly installed on the outer wall of one of the support plates 2, and a cylinder 9 is fixedly installed on the outer walls of both sides of the upper hopper 4 through a connecting mechanism. The connecting mechanism includes a connecting plate 8 fixedly installed on the outer wall of the upper hopper 4, and the cylinder 9 is fixedly mounted on the inner wall of the connecting plate 8.

[0023] Scrapers 10 are fixedly installed at the telescopic ends of the two cylinders 9. A collecting box 12 and an exhaust fan 13 are fixedly installed on the upper end surface of the transport equipment 1 through a supporting mechanism. The supporting mechanism includes a supporting frame 11 fixedly installed on the upper end surface of the transport equipment 1. The collecting box 12 and the exhaust fan 13 are both fixedly installed on the upper end surface of the support frame 11. The inlet pipe of the exhaust fan 13 extends to the interior of the collecting box 12. A connecting pipe 14 communicating with the interior is fixedly installed on the outer wall of the collecting box 12. A suction hood 15 is fixedly connected to the end of the connecting pipe 14. A filter plate 16 is fixedly installed inside the collecting box 12.

[0024] A cover plate 18 is slidably installed on the upper end surface of the collection box 12 through a mounting groove, and a sealing gasket 17 is fixedly installed on the bottom wall of the cover plate 18. The sealing gasket 17 is made of rubber. A fixing pin 19 is slidably installed through the outer wall of the collection box 12. A socket that cooperates with the fixing pin 19 is opened on the outer wall of the cover plate 18. A shift block 20 is fixedly installed on the outer wall of the fixing pin 19. The inner wall of the shift block 20 is connected to the outer wall of the collection box 12 through a fixing mechanism. The fixing mechanism includes a fixing spring 21 installed on the outer wall of the fixing pin 19. The two ends of the fixing spring 21 are elastically connected to the outer wall of the collection box 12 and the inner wall of the shift block 20 respectively.

[0025] When the utility model is used, cotton yarn can be put into the loading hopper 4. When the cotton yarn is loaded into the carding machine, the motor 7 can drive one of the clamping rollers 5 to rotate, and one of the clamping rollers 5 can drive the other clamping roller 5 to rotate through two gears 6 that mesh with each other, thereby making the two clamping rollers 5 rotate toward each other and clamp the cotton yarn during the rotation, so that the cotton yarn can be clamped into sheets. The sheet-like cotton yarn can fall on the upper end surface of the transport device 1 and be transported. During the transportation process, the exhaust fan 13 is started to form a negative pressure inside the collection box 12. At this time, the negative pressure can generate corresponding suction, and the suction can be used to extract the flying catkins during transportation through the cooperation of the connecting pipe 14 and the suction cover 15, and intercept it inside the collection box 12 for collection through the cooperation of the filter plate 16;

[0026] When cotton yarn is stuck on the outer walls of the two clamping rollers 5, the cylinders 9 on both sides can respectively drive the scrapers 10 on the same side to move, so that the two scrapers 10 can respectively contact the outer walls of the adjacent clamping rollers 5. As the clamping rollers 5 rotate, the scrapers 10 can scrape off the cotton yarn stuck on their outer walls, thereby avoiding affecting the clamping effect of the clamping rollers 5 on the cotton yarn and preventing the feeding efficiency of the carding machine from being reduced. When it is necessary to clean the flying catkins inside the collecting box 12, the dial block 20 can be moved to drive the fixing pin 19 to move out of the socket, thereby releasing the fixation of the cover plate 18 inside the mounting groove, and then the cover plate 18 can be removed from the upper end surface of the collecting box 12, and then the flying catkins inside the collecting box 12 can be cleaned.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
