Abstract
Description
Technical Field
[0001] This utility model belongs to the field of textile equipment and relates to a carding machine, specifically to a bearing anti-hair jamming installation structure for a carding machine. 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] When the combing rollers inside the combing box rotate at high speed, they generate a large amount of fly hair. This fly hair can get caught in the running bearings of the combing machine. Too much fly hair can even cause the bearings to seize up, damaging the equipment. Utility Model Content
[0004] To address the problems described in the background art, this utility model provides a bearing anti-hair-jamming installation structure for a combing machine, which can effectively prevent flying hair from getting caught inside the bearing.
[0005] A bearing anti-hair jamming installation structure for a combing machine is disclosed: the bearing is installed in the bearing mounting hole of the combing box, specifically by the outer ring of the bearing and the bearing mounting hole being interference fit to achieve installation; the rotating shaft passes through the bearing and is fixedly connected to the inner ring of the bearing; and a combing roller is fixedly connected to one end of the rotating shaft located inside the combing box.
[0006] The combing roller has an assembly hole at its end face near the bearing. One end of the bearing, located inside the combing box, protrudes from the bearing mounting hole and is situated within the assembly hole of the combing roller. A retaining ring is fixedly installed on the outer ring of the protruding end of the bearing, also located within the assembly hole of the combing roller. A protective sleeve is fitted onto the outer ring of the bearing, positioned between the retaining ring and the inner wall of the combing box. The outer wall of the protective sleeve and the inner wall of the assembly hole of the combing roller are fitted with a clearance, allowing lubricating grease to be injected into this clearance to ensure smooth operation of the combing roller. This clearance is also very small, specifically 0.1mm, preventing hair from entering the assembly hole of the combing roller through this clearance, thus preventing hair from being drawn into the bearing from this end. The protective sleeve is specifically a copper sleeve, and the retaining ring limits its position, ensuring stable installation on the outer ring of the bearing and preventing it from detaching.
[0007] Furthermore, a pulley is fixedly connected to the other end of the rotating shaft. The pulley is used to drive the rotating shaft. A retaining ring is provided between the pulley and the bearing end face. The retaining ring is fixedly connected to the outer ring of the bearing. The pulley is located inside the retaining ring and is in clearance fit with the retaining ring. This clearance does not affect the rotation of the pulley. At the same time, this clearance is too small, specifically 0.1mm, so that the fly hair outside the combing box cannot be rolled into the bearing through this end gap.
[0008] Preferably, the outer ring of the bearing has an annular groove at the corresponding position of the retaining spring, and the retaining spring is placed in the annular groove, so as to achieve the limiting and fixing installation of the retaining spring.
[0009] Through the above technical solutions, this utility model has at least the following beneficial effects:
[0010] The anti-hair-jamming mounting structure for the bearing of the carding machine described in this application, through the coordinated design of components such as the mounting holes of the carding rollers, the outer ring of the bearing, the retaining spring, and the protective sleeve inside the carding box, can prevent hair from the inside of the carding box from being rolled into the bearing from one end. In a further embodiment, at the other end of the bearing, through the coordinated design of components such as the pulley, the retaining ring, and the outer ring of the bearing, hair from outside the carding box cannot be rolled into the bearing from that end. Thus, the anti-hair-jamming mounting structure for the bearing of the carding machine described in this application provides good protection at both ends of the bearing, effectively preventing hair from being rolled into the bearing and causing it to seize.

[0015] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0016] refer to Figure 1 and Figure 2 A bearing anti-hair jamming installation structure for a combing machine is provided. The bearing 1 is installed in the bearing mounting hole 201 of the combing box 2. Specifically, the outer ring 101 of the bearing is interference-fitted with the bearing mounting hole 201 to achieve the installation. The rotating shaft 3 passes through the bearing 1 and is fixedly connected to the inner ring 102 of the bearing. The end of the rotating shaft 3 located inside the combing box 2 is fixedly connected to the combing roller 4.
[0017] The combing roller 4 has an assembly hole 401 at its end face near the bearing 1. One end of the bearing 1, located inside the combing box 2, protrudes from the bearing mounting hole 201 and is located within the assembly hole 401 of the combing roller 4. A retaining ring 5 is fixedly installed on the outer ring of the protruding end of the bearing 1. The retaining ring 5 is also located within the assembly hole 401 of the combing roller 4. An annular groove is provided on the outer ring 101 of the bearing at the corresponding position of the retaining ring 5. The retaining ring 5 is placed in the annular groove, thereby achieving the limiting and fixed installation of the retaining ring 5.
[0018] A protective sleeve 6 is fitted onto the outer ring 101 of the bearing. The protective sleeve 6 is located between the retaining spring 5 and the inner wall of the combing box 2. The outer wall of the protective sleeve 6 is fitted with the inner wall of the mounting hole 401 of the combing roller 4 with a clearance. Lubricating grease can be injected into this clearance to allow the combing roller 4 to operate smoothly. At the same time, this clearance is too small, specifically 0.1mm, so that the fly hair in the combing box 2 cannot enter the mounting hole 401 of the combing roller 4 through this clearance, thereby preventing the fly hair inside the combing box 2 from being rolled into the bearing 1 from this end. The protective sleeve 6 is specifically a copper sleeve. The retaining spring 5 limits the protective sleeve 6 so that it can be stably installed on the outer ring 101 of the bearing and prevents it from falling off the outer ring 101 of the bearing.
[0019] The other end of the rotating shaft 3 is fixedly connected to a pulley 7, which is used to drive the rotating shaft 3. A retaining ring 8 is provided between the pulley 7 and the end face of the bearing 1. The retaining ring 8 is fixedly connected to the outer ring 101 of the bearing. The pulley 7 is partially located inside the retaining ring 8 and is clearance-fitted with the retaining ring 8. This clearance does not affect the rotation of the pulley 7, and at the same time, this clearance is too small, specifically 0.1mm, so that the fly hair outside the combing box 2 cannot be rolled into the bearing 1 through this end gap.
