Description

Technical Field

[0001] This utility model belongs to the field of textile equipment, and specifically relates to a combing roller structure. Background Technology

[0002] The carding machine is a key piece of equipment in the textile industry used to comb fibers. It is mainly used to further comb the opened fibers into parallel, uniform and clean fiber webs, providing high-quality raw materials for subsequent spinning or nonwoven fabric production.

[0003] The combing roller is the main component of the combing machine. The existing combing rollers usually have a relatively simple structure and have shortcomings such as heavy weight, lack of hair storage function, and unbalanced operation. Utility Model Content

[0004] To address the shortcomings of existing combing rollers described in the background art, this application provides a combing roller structure in which mounting holes are provided axially on the combing roller body, and annular grooves are provided around the mounting holes on both ends of the combing roller body. The cross-section of the annular groove is an isosceles trapezoid, and the opening surface of the annular groove is smaller than the bottom surface of the annular groove. This design of the annular groove can reduce the weight of the combing roller, and the annular groove can also store lint, which can prevent the fly hair generated during fiber combing from flying everywhere.

[0005] Preferably, the depth of the annular groove is 15-25mm, more preferably 20mm, and the isosceles trapezoidal cross-section of the annular groove has an angle of 5-10° with the hypotenuse of the groove and the axis of the combing roller body, more preferably 6°. This type of annular groove also facilitates the cleaning of lint inside the annular groove.

[0006] Furthermore, the mounting hole is a stepped hole, which is divided into an assembly hole and a shaft hole. The diameter of the assembly hole is larger than that of the shaft hole. The shaft hole of the combing roller body is used to fix it to the end of the rotating shaft, and its assembly hole is used to make clearance fit with the outer ring of the bearing on the rotating shaft. In this way, the center of gravity of the combing roller connected to the rotating shaft can be located on the outer side, increasing the lever arm. The outward shift of the center of gravity can also form a good balance with the bearing and other components on the other side of the rotating shaft, so that the combing roller rotates smoothly.

[0007] Furthermore, combing burrs are fixedly connected to the circumferential surface of the combing roller body.

[0008] Through the above technical solutions, this utility model has at least the following beneficial effects:

[0009] The combing roller structure described in this application features a special design of annular grooves on both ends, which reduces weight, thereby lessening the load on the drive motor and lowering the manufacturing cost of the combing roller. At the same time, the annular grooves can also store lint, preventing the fly hair generated during fiber combing from flying everywhere. The special design of its mounting holes allows the center of gravity of the combing roller connected to the rotating shaft to be on the outer side, increasing the lever arm. The outward shift of the center of gravity can also form a good balance with the bearings and other components on the other end of the rotating shaft, making the combing roller rotate smoothly.
