Description

Technical Field

[0001] The utility model relates to the technical field of rubber rollers, in particular to an air-spinning guide rubber roller. Background Art

[0002] Rubber rollers are roll-shaped products made of metal or other materials as the core and rubber covered by vulcanization. Air-spinning rubber rollers need to be made of high-quality materials, usually high-quality carbon steel, alloy steel, stainless steel and other materials. The materials are required to have high strength, wear resistance, corrosion resistance and other characteristics to meet the use requirements in the production process. The rubber rollers currently used in the textile industry include single-layer rubber rollers, double-layer rubber rollers and aluminum-lined rubber rollers. They are the main drafting components of spinning equipment such as cotton, wool, linen, silk, and chemical fibers. They form a drafting mechanism with metal bearings, rotate with the bearings, can well control the fiber, and stabilize the draft. In order to improve the processing efficiency of textiles, a rubber roller is needed, but the existing rubber rollers still have the following shortcomings:

[0003] For example, the utility model with application number 202123272866.2 discloses a textile rubber roller with high efficiency in cooling. The utility model cooperates with the rubber roller body and the water inlet assembly to make the cooling water completely contact with the inner wall of the rubber roller body, thereby avoiding voids inside the rubber roller body, thereby improving the cooling effect of the textile rubber roller. At the same time, the spiral guide vane can rotate the cooling water to mix the cooling water on the upper and lower sides of the rubber roller body, thereby accelerating heat transfer, avoiding uneven heat absorption of the cooling water, and improving the heat absorption efficiency of the cooling water. However, similar to the comparative documents of the above-mentioned application, when the existing rubber rollers are used, since most rubber rollers and roller cores are of an integrated structure, the rubber rollers cannot replace the rubber roller body or the core shaft separately, resulting in a waste of resources, and causing the practicality of the rubber rollers to decrease and the efficiency of use to decrease.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an air-spinning guide rubber roller is proposed. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air-spinning guide rubber roller, comprising a first spliced ​​rubber roller body and an installation assembly, a second spliced ​​rubber roller body is distributed outside the first spliced ​​rubber roller body, and a cross installation groove is opened inside the first spliced ​​rubber roller body, an installation assembly is arranged outside the first spliced ​​rubber roller body, and the installation assembly comprises a cross roller core, a fixed mandrel, a threaded installation groove, a limit installation piece, a docking block, a clamping groove, a docking groove and a clamping block, fixed mandrels are fixed at both ends of the cross roller core, and a threaded installation groove is opened on the outside of the fixed mandrel close to the cross roller core, and a limit installation piece is connected to the outside of the threaded installation groove, a docking block is added on one side of the outside of the first spliced ​​rubber roller body, and clamping grooves are opened on the four corners of the outside of the docking block, a docking groove is opened on one side of the inside of the second spliced ​​rubber roller body, and clamping blocks are added on the four corners of the inside of the docking groove, and a protective assembly is arranged inside the first spliced ​​rubber roller body.

[0007] Furthermore, the inner dimension of the cross mounting groove matches the outer dimension of the cross roller core, and the cross roller core is connected to the first spliced ​​rubber roller body through the cross mounting groove.

[0008] Furthermore, the outer dimensions of the threaded mounting groove match the inner dimensions of the position limiting mounting piece, and the position limiting mounting piece is rotatably connected to the fixed core shaft via the threaded mounting groove.

[0009] Furthermore, the outer dimensions of the docking block match the inner dimensions of the docking groove, and the first splicing rubber roller body is connected to the second splicing rubber roller body through the docking block.

[0010] Furthermore, the inner dimensions of the clamping slot match the outer dimensions of the clamping block, and the clamping block is embeddedly connected to the docking block via the clamping slot.

[0011] Furthermore, the protective component includes an anti-adhesion layer, an elastic layer, a wear-resistant layer, a thermal insulation layer and a rubber layer. The elastic layer is arranged on the inner side of the anti-adhesion layer, and the wear-resistant layer is arranged on the inner side of the elastic layer. A thermal insulation layer is additionally arranged on the inner side of the wear-resistant layer, and a rubber layer is arranged inside the thermal insulation layer.

[0012] Furthermore, an elastic layer and a heat-insulating layer are respectively arranged on the upper and lower sides of the wear-resistant layer, and the wear-resistant layer is arranged and confined between the elastic layer and the heat-insulating layer.

[0013] Furthermore, the outer side of the heat insulation layer is flush with the outer side of the rubber layer, and the outer side of the heat insulation layer is tightly fitted with the outer side of the rubber layer.

[0014] The utility model provides an air-spinning guide rubber roller, which has the following beneficial effects:

[0015] 1. The utility model can avoid the problem that most rubber rollers and roller cores are integrated structures by using the installation assembly arranged on the outside of the first spliced ​​rubber roller body when the air-spinning guide rubber roller is used, so that the rubber roller cannot replace the rubber roller body or the core shaft alone, which wastes resources and causes the problem of reduced practicality of the rubber roller. The internal size of the cross installation groove matches the external size of the cross roller core, so that the cross roller core is installed into the first spliced ​​rubber roller body through the cross installation groove, and the external size of the threaded installation groove opened on the outside of the fixed core shaft fixedly installed on both sides of the outside of the cross roller core matches the internal size of the limit installation piece, and then the limit installation piece is rotatably installed on the fixed core shaft through the threaded installation groove. The outside of the cross roller core is limited by the limiting installation part, and at the same time, the external size of the docking block added on the outside of the first spliced ​​rubber roller body matches the internal size of the docking groove opened on the outside of the second spliced ​​rubber roller body, and the internal size of the clamping groove opened on the outside of the docking block matches the external size of the clamping block added inside the docking groove, so that the docking block is installed into the docking groove through the clamping groove and the clamping block, so that the first spliced ​​rubber roller body and the second spliced ​​rubber roller body are docked and installed, and after several rubber rollers are installed, the multiple rubber rollers are limited by the limiting installation part at the other end, so that the rubber rollers are easy to disassemble and install, and the mobility of the rubber rollers during use is further improved.

[0016] 2. The utility model can prevent the majority of rubber rollers from contacting with fibers during the production process by setting a protective component when the air-spinning guide rubber roller is in use, through the protective component set inside the first spliced ​​rubber roller body, which causes the fibers to easily adhere to the rubber roller, making the fibers bloated and reducing the use efficiency of the rubber roller. The anti-adhesion layer set on the outermost side of the first spliced ​​rubber roller body prevents the fibers from adhering to the rubber roller, thereby improving the production efficiency and product quality of the fibers. The elastic layer set on the inner side of the anti-adhesion layer makes the rubber roller as a whole have a certain elasticity, thereby better contacting with the fibers, thereby improving the yield rate of fiber processing. The wear resistance of the rubber roller as a whole is increased by the wear-resistant layer, thereby extending the overall service life of the rubber roller. The heat insulation layer is used to prevent the rubber roller from overheating after contacting the fibers. At the same time, the overall weight of the rubber roller is increased by the rubber layer, making the fiber processing more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
