Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carding machine equipment, in particular to a sealing structure for the shaft ends of the upper and lower rollers of a carding machine. Background Art
[0002] In the field of textile machinery, as an important equipment for fiber pretreatment, the operating stability and sealing effect of a carding machine are directly related to the quality of fiber treatment and production efficiency. In the design of a carding machine, the shaft end sealing of the upper and lower rollers is an important technical link, which can effectively enhance the preservation effect of lubricating oil on the shaft and reduce the intrusion of external impurities.
[0003] At present, most of the shaft ends of the upper and lower rollers of a carding machine are sealed by adding felt rings to avoid the entanglement of cotton fibers. However, when the shaft end rotates, friction is likely to occur between the felt ring on the shaft end and the wallboard, resulting in wear of the felt ring and heat deformation of the wallboard. Moreover, after the felt ring has been running for a long time and is worn, it is very easy to entangle cotton fibers, affecting the normal operation of the carding machine. Summary of the Utility Model
[0004] In view of the problem that the above-mentioned method of sealing the shaft end by adding a felt ring is prone to wear and is likely to entangle cotton fibers after wear, the utility model discloses a sealing structure for the shaft ends of the upper and lower rollers of a carding machine.
[0005] To solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A sealing structure for the shaft ends of the upper and lower rollers of a carding machine includes a roller body and a shaft sleeve. The shaft sleeve is sleeved on the roller neck of the roller body in a matching manner and is connected to the roller body through a bearing. A groove is provided at the end of the roller body of the roller, and one end of the shaft sleeve has a protrusion adapted to the groove. The shaft sleeve is connected to the groove through the protrusion.
[0007] Further, the shaft sleeve has a through hole adapted to the roller neck, and the shaft head at one end of the roller body protrudes from the shaft sleeve and is connected with a plurality of synchronous belt wheels.
[0008] Further, the shaft sleeve includes a first connection section, a second connection section, and a third connection section, and the second connection section is located between the first connection section and the third connection section.
[0009] Further, the cross-section of one side of the whole formed by the first connection section, the second connection section, and the third connection section is U-shaped.
[0010] Further, the protrusion is located on the outer side surface of the first connection section.
[0011] Further, the groove includes a first groove and a second groove. The second groove is located inside the first groove. The first groove is adapted to the first connecting section, and the second groove is adapted to the protrusion.
[0012] Further, the bearing is arranged inside the third connecting section, and the bushing is sleeved on the shaft head of the roll body in a matching manner.
[0013] Further, a sealing portion is arranged inside the third connecting section. The sealing portion is located outside the bearing, and a retaining ring is arranged between the sealing portion and the bearing.
[0014] Further, the sealing portion has a connecting hole and is sleeved on the shaft head in a matching manner through the connecting hole. A sealing ring is arranged between the sealing portion and the third connecting section.
[0015] Further, the roll body includes an upper roll body and a lower roll body, and a photoelectric detection structure is arranged on the bushing on one side of the upper roll.
[0016] The beneficial effects of the present utility model are as follows: By cooperating the bushing with the roll body to form a zigzag circuit, the present utility model can effectively reduce the entry of fibers into the roll body and avoid winding. The present utility model does not need to use a felt ring for sealing, preventing friction and heat generation with the wall panel, and avoiding the influence of part thermal deformation on the stability of part accuracy. The present utility model uses a sealing portion to prevent fibers and dust from entering the bushing and adhering to the bearing, thereby prolonging the service life of the bearing.
