Description

Technical Field

[0001] The utility model belongs to the technical field of cold rolling rollers, in particular to an oil-removing and stain-removing non-woven fabric roller. Background Art

[0002] A non-woven degreasing roller is a device that removes oil and stains from the surface of the product by rolling. During the non-woven fabric production process, the fiber web is pressed in a press to form a dense non-woven fabric, achieving a certain hardness, and then lathe-ground to dimensional accuracy. The roller can cause the flange's inertial rotation to cause the guide screws to loosen. The flange's embedded shaft is designed as a square shaft, which, while effective in preventing inertial rotation, presents a significant manufacturing challenge. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to improve an oil-removing and stain-removing non-woven fabric roller which can prevent the flange from rotating inertia during use.

[0004] In order to solve the above technical problems, the present invention is implemented through the following technical solutions: a non-woven fabric roller for removing oil and stains, comprising a roller core, a non-woven fabric roller sleeve, a flange and a roller shaft, the inner end of the roller shaft is set as a threaded rod structure, and a first limiting groove is provided in an annular array on the roller core, and a first limiting protrusion matching the first limiting groove is provided in the non-woven fabric roller sleeve, and the non-woven fabric roller sleeve is slidably sleeved and installed on the roller core, and the first limiting protrusion is slidingly embedded in the first limiting groove with a clearance fit, the inner end face of the flange is set as a protrusion structure, and grooves matching the inner end face of the flange are provided at both ends of the roller core, and the two flanges are slidably embedded in the grooves at both ends of the roller core, and the threaded rod structure of the roller shaft is screwed into the roller core and the flange is pressed and fixed.

[0005] Preferably, four first limiting grooves are arranged in a ring array.

[0006] Preferably, it also includes a limiting ring, and a second limiting groove corresponding to the first limiting groove is arranged in an annular array on the flange, and second limiting protrusions matching the first limiting groove and the second limiting groove are arranged in an annular array on both sides of the limiting ring. The limiting ring is installed on the first limiting protrusion of the non-woven fabric roller sleeve with a sliding clearance, and the second limiting protrusion is embedded in the first limiting groove and the second limiting groove with a clearance.

[0007] Preferably, mesh anti-slip patterns are provided on both sides of the limiting ring.

[0008] Compared with existing technologies, the present invention offers the advantage of threaded mounting of the roller shaft with a compression flange, making it easier to install, maintain, and replace the non-woven fabric roller sleeve. By providing a retaining ring, the second retaining protrusions on either side of the retaining ring fit within the first and second retaining grooves, providing inertial anti-rotation protection for the flange. This improves the stability of the oil-removing and stain-removing non-woven fabric roller during use and prevents the flange and roller shaft from becoming loose. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention is described in detail below in conjunction with specific embodiments:

[0017] like Figures 1 to 6 The oil-removing and stain-removing non-woven fabric roller shown includes a roller core 1, a non-woven fabric roller sleeve 2, a flange 3 and a roller shaft 4, the inner end of the roller shaft 4 is set as a threaded rod structure 41, and the roller core 1 is provided with a first limiting groove 11 in an annular array, and the non-woven fabric roller sleeve 2 is provided with a first limiting protrusion 21 that cooperates with the first limiting groove 11. The non-woven fabric roller sleeve 2 is slidably sleeved and installed on the roller core 1, and the first limiting protrusion 21 is slidingly embedded in the first limiting groove 11 with a clearance fit. The inner end face of the flange 3 is set as a convex structure, and grooves that cooperate with the inner end face of the flange 3 are provided at both ends of the roller core 1. The two flanges 3 are slidably embedded in the grooves at both ends of the roller core 1, and the threaded rod structure 41 of the roller shaft 4 is screwed into the roller core 1 and presses the flange 3 tightly.

[0018] As a preferred arrangement structure of the first limiting grooves 11 , four first limiting grooves 11 are arranged in a ring array.

[0019] When the flange 3 rotates with the roller core 1, there is a problem that the flange 3 shakes and the threaded rod structure 41 of the roller shaft 4 is loosened. Therefore, a limiting ring 6 is also included, and the limiting ring 6 is installed in the gap 5 between the roller core 1 and the flange 3. The flange 3 is provided with a second limiting groove 31 corresponding to the first limiting groove 11 in an annular array, and second limiting protrusions 61 matching the first limiting groove 11 and the second limiting groove 31 are provided in an annular array on both sides of the limiting ring 6. The limiting ring 6 is installed on the first limiting protrusion 21 of the non-woven fabric roller sleeve 2 with a sliding clearance fit, and the second limiting protrusion 61 is loosely fitted and embedded in the first limiting groove 11 and the second limiting groove 31. The second limiting protrusion 61 of the limiting ring 6 limits and fixes the flange 3 to prevent it from freely rotating to the threaded rod structure 41 of the roller shaft 4 and loosening. At the same time, the two ends of the first limiting protrusion 21 do not extend to the outer end surface of the non-woven fabric roller sleeve 2 to avoid interference between the first limiting protrusion 21 and the second limiting protrusion 61. The two sides of the limit ring 6 are provided with mesh anti-skid patterns, which further increase the contact friction between the limit ring 6 and the roller core 1 and the flange 3, and compensate for the problem of displacement of the limit ring 6 caused by the slight movement gap existing in the clearance fit.
