Description

Technical Field

[0001] This utility model relates to the field of textile equipment, specifically to a combing and cleaning machine that facilitates adjustment of combing height. Background Technology

[0002] A carding and combing machine is a piece of equipment used in textile production that transforms raw fibers into high-quality slivers, laying the foundation for subsequent spinning processes. It is one of the indispensable key pieces of equipment in a modern spinning production line. The slivers are typically wound in an orderly fashion inside a drum.

[0003] Chinese Patent CN213896088U discloses a carding and combing machine with adjustable carding height, comprising a base, a guide wheel, a coiler, and a material bin. A first motor is fixed inside the base, and a bevel gear is mounted at the front end of the first motor. The bevel gear meshes with the first gear. A bracket is fixed to the top left side of the base, and support rods are distributed on the bracket. A second motor is fixed to the bottom of the bracket, and a second gear is mounted at the top of the second motor. The second gear meshes with a threaded rod, and the threaded rod passes through the bracket. A cover plate is fixed to the bottom of the threaded rod, and a coiler is mounted on the cover plate. A material bin is located at the lower end of the coiler, and the first gear is located at the bottom of the material bin. This carding and combing machine with adjustable carding height, equipped with a second motor and a threaded rod, allows the second motor to rotate and engage the second gear with the threaded rod, preventing material from becoming tangled and affecting the quality of the finished product due to the inability to raise or lower the material bin.

[0004] The above-disclosed technical solution has the following shortcomings: setting the threaded rod vertically to adjust the combing height will result in a large vertical dimension of the equipment, and the threaded rod that moves up and down also poses certain safety hazards. Utility Model Content

[0005] The purpose of this invention is to address the safety hazards posed by the large vertical dimension of the equipment caused by the threaded rod in the background technology, and to propose a combing and cleaning machine that facilitates adjustment of the combing height.

[0006] The technical solution of this utility model: a combing and cleaning machine that facilitates adjustment of combing height, comprising:

[0007] The frame has a turntable mounted on its bottom and a power device that drives the turntable to rotate.

[0008] The box body is located on the top of the frame. Rigid chain clearance grooves are provided at the bottom of the box body and the top of the frame. An inlet for cotton strips to enter is provided at the top of the box body.

[0009] The rigid chain retraction box is slidably mounted on the inner wall of the bottom of the box body. Inside it is a power mechanism for retracting and extending the rigid chain. The rigid chain passes through the rigid chain avoidance groove and extends vertically and rigidly downward.

[0010] The carding box is located at the bottom of the rigid chain. The cotton sliver passes through the carding box, which is equipped with a conveying mechanism that drives the cotton sliver downward.

[0011] The control system is located inside the box and is connected to the telescopic device and the conveying mechanism.

[0012] Preferably, the power unit is located below the turntable, and the rotation output shaft of the power unit is connected to the bottom of the turntable; multiple elastic plates are provided on the frame, and limit rollers are rotatably installed at the ends of the elastic plates, and the limit rollers make rolling contact with the outer wall of the material barrel.

[0013] Preferably, a telescopic device is provided on the inner wall of the bottom of the box, and the telescopic end of the telescopic device is connected to the outer wall of the rigid chain storage box.

[0014] Preferably, a guide frame is provided on the box body, and multiple guide wheels are provided on the guide frame. The guide wheels guide and convey the cotton strips after they are formed, and the cotton strips enter from the top inlet of the box body.

[0015] Preferably, the conveying mechanism includes two conveying guide wheels rotatably disposed inside the carding box, and a power mechanism disposed on the carding box to drive the two conveying guide wheels to rotate in opposite directions.

[0016] Preferably, motor cable clearance slots are provided at the bottom of the housing and the top of the frame, through which the motor cable of the power mechanism passes and is connected to the control system.

[0017] Preferably, the control system is equipped with two rotating conveyor rollers, and the motor cable is driven by the two conveyor rollers to always tend to move into the control system.

[0018] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: After being guided by the guide wheel, the cotton sliver passes sequentially through the top inlet of the box, the rigid chain avoidance groove, and the combing box. During the combing and receiving process, the telescopic device continuously drives the rigid chain receiving and receiving box to move back and forth, changing the bottom coiling position of the cotton sliver. As the coiling continues, the rigid chain continuously contracts upward, thereby continuously increasing the combing height. The material bucket rotates under the drive of the power device, thereby continuously coiling the cotton sliver inside the material bucket. Changing the combing height through the rigid chain does not additionally increase the vertical dimension of the equipment, and the up-and-down movement of the rigid chain poses no safety hazard.

[0029] The carding box 17 is located at the bottom of the rigid chain 11. The cotton sliver 16 passes through the carding box 17. The carding box 17 is equipped with a conveying mechanism that drives the cotton sliver 16 to move downward.

[0030] The control system 20 is located inside the box 7 and is connected to the telescopic device 13 and the conveying mechanism.

[0031] Example 2

[0032] like Figure 3 As shown, this utility model proposes a combing machine that facilitates adjustment of combing height. Compared with Embodiment 1, this embodiment details the moving structure of the power unit 3 and the rigid chain take-up and drop box 9.

[0033] The power unit 3 is located below the turntable 2, and the rotation output shaft of the power unit 3 is connected to the bottom of the turntable 2. Multiple elastic plates 6 are provided on the frame 1, and limiting rollers 5 are rotatably provided at the ends of the elastic plates 6. The limiting rollers 5 roll in contact with the outer wall of the material bucket 4.

The motor cable 19 supplies power to the second motor and transmits control signals. To ensure that the motor cable 19 remains taut during the up-and-down movement of the comb box 17, two rotating conveyor rollers are installed inside the control system 20. The motor cable 19 is driven by the two conveyor rollers and always tends to move into the control system 20, so that the exposed motor cable 19 remains taut. To ensure the stability of the joint, a cable holder is installed on the comb box 17, through which the motor cable 19 passes.

[0038] In summary, during use, the cotton slivers 16, guided by the guide wheel 15, pass sequentially through the top inlet of the box 7, the rigid chain clearance groove 12, and the combing box 17. During the combing and collecting process of the cotton slivers 16, the telescopic device 13 continuously drives the rigid chain take-up and take-down box 9 to move back and forth, changing the bottom coiling position of the cotton slivers 16. As the coiling continues, the rigid chain continuously contracts upward, thereby continuously increasing the combing height. The material bin 4 rotates under the drive of the power device, thereby continuously coiling the cotton slivers 16 inside the material bin 4. In this invention, changing the combing height through the rigid chain 11 does not additionally increase the vertical dimension of the equipment, and the up-and-down movement of the rigid chain 11 poses no safety hazard.
