Description

Technical Field

[0001] The utility model belongs to the technical field of wire stripping machines, in particular to a wire stripping machine roller. Background Art

[0002] Wire stripping machine is a machine that separates the metal from the plastic and rubber of waste wires or cables. The wire stripping machine feeds the wires and cables into the equipment through the feed hole, and then the outer skin of the wires and cables is cut off by the high-speed rotating cutter.

[0003] The existing wire stripping equipment, such as the multifunctional wire stripping machine disclosed in the Chinese patent (application number 202021699454X), includes a knife roller and a roller. The knife roller and the roller are arranged up and down and can be switched up and down. The wire stripping working area is between the knife roller and the roller. Several feed slots of the roller are provided with grooves to increase friction. The cable moves forward by rolling through the grooves. However, due to the lack of grip in the grooves of the feed slot, the cable cannot move forward smoothly, resulting in slippage. How to make the anti-slip ability of the wire stripping machine roller better and use it longer. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a wire stripping machine roller.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a wire stripping machine roller, including a shaft body, on which a plurality of rollers arranged unequally in the axial direction are integrally formed, the roller having an outer circumferential surface coaxial with the shaft body and an inclined surface connecting the outer circumferential surface to the shaft body, two adjacent inclined surfaces and the shaft body forming a feed trough, the inclined surface being provided with a plurality of axially arranged stepped serrated rings, the outer diameters of the plurality of serrated rings gradually becoming smaller toward the bottom of the feed trough.

[0006] Several rollers arranged unequally along the axial direction form a wire stripping work area suitable for wires or cables of multiple sizes; two adjacent inclined surfaces and the shaft body form a feed trough which is a trapezoidal trough that is larger on the outside and smaller on the inside, and the feed trough is the wire stripping work area; a number of axially arranged stepped serrated rings are provided on the inclined surface of the feed trough, and the serrated rings have good grip and can hook the waste wires or cables to transport them to prevent them from slipping; a blade opposite to the feed trough is fixed on the wire stripping machine, and the waste wires or cables are hooked by the serrated ring in the feed trough and transported to the blade to be separated, separating the metal and plastic.

[0007] Furthermore, the sawtooth ring has a plurality of sawtooth blocks equally divided in the circumferential direction, and the sawtooth blocks include sawtooth outer cylindrical surfaces, sawtooth side surfaces, and sawtooth triangular surfaces connecting the sawtooth outer cylindrical surfaces and the sawtooth side surfaces. The sawtooth blocks have gripping power, and the vertex of the sawtooth triangular surface of the sawtooth blocks can hook the wires or cables to transport them forward. The sawtooth blocks can prevent slipping, are relatively wear-resistant, can be used for a long time, and extend the service life of the roller.

[0008] Furthermore, the bottom edge of the sawtooth triangle extends toward the vertex of the adjacent sawtooth triangle but does not approach it, forming a sawtooth inclined triangle. The distance gap between the bottom edge of the sawtooth inclined triangle and the vertex of the sawtooth inclined triangle enables the sawtooth block to have better grip, and the distance gap between the vertex of the sawtooth inclined triangle to the vertex of the sawtooth triangle enables the sawtooth block to have more wear space, thereby extending the service life of the roller.

[0009] Furthermore, the number of sawtooth blocks on each sawtooth ring is the same, which is convenient for processing and manufacturing.

[0010] Furthermore, the sawtooth blocks on each sawtooth ring are arranged one by one, and the sawtooth triangular faces on the correspondingly arranged sawtooth blocks are on the same plane, and the sawtooth inclined triangular faces are also on the same plane, which is convenient for machining and manufacturing.

[0011] Furthermore, one of the inclined surfaces has two or more serrated rings.

[0012] Furthermore, one of the inclined surfaces has three circles of sawtooth rings.

[0013] Furthermore, one of the inclined surfaces has four circles of sawtooth rings.

[0014] Furthermore, the width of the feed trough varies with the distance between the two rollers.

[0015] Compared with the prior art, the technical effects of the utility model are as follows: a stepped serrated ring is arranged on the inclined surface, and the serrated ring has a gripping force that can better hook the wires or cables for transportation to prevent them from slipping; the serrated block structure on the serrated ring increases the gripping force on the wires or cables and increases the wear resistance of the serrated blocks, preventing the wires or cables from slipping during transportation, allowing the roller to better perform press material transportation and extending the service life of the wire stripping machine roller; the serrated blocks on the serrated ring are arranged one by one, and the serrated triangular surfaces on the correspondingly arranged serrated blocks are on the same plane, and the serrated inclined triangular surfaces are also on the same plane, making processing more convenient.

DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] according to Figures 1 to 3 As shown: a wire stripping machine roller, including an axis body 1, on which a plurality of rollers 11 arranged along the axis are integrally formed, the spacing between two adjacent rollers 11 is not equal, a feed groove 13 is formed between two adjacent rollers 11, and the width of the feed groove 13 varies with the distance between the two rollers 11. The plurality of rollers 11 arranged unequally along the axial direction form a wire stripping working area suitable for wires or cables of multiple sizes, and the feed groove 13 is the working area.

[0022] The roller 11 has an outer circumferential surface 11a coaxial with the shaft body 1 and an inclined surface 11b connecting the outer circumferential surface 11a with the shaft body 1. The feed trough 13 is composed of two adjacent inclined surfaces 11b and the shaft body 1. The inclined surface 11b is provided with a plurality of axially arranged stepped sawtooth rings 12, which can increase the gripping force on the wires or cables. The outer diameters of the plurality of sawtooth rings 12 gradually decrease toward the bottom of the feed trough 13, that is, the sawtooth rings 12 arranged on the inclined surface 11b are inclined along with the inclined surface 11b, which can provide better gripping force to prevent the wires or cables from slipping and allow the wires or cables to pass smoothly in the wire stripping working area.

[0023] The sawtooth ring 12 has a plurality of sawtooth blocks 121 equally divided in the circumferential direction, and the sawtooth block 121 includes a sawtooth outer cylindrical surface 121a, a sawtooth side surface 121b, and a sawtooth triangular surface 121c connecting the sawtooth outer cylindrical surface 121a and the sawtooth side surface 121b. The sawtooth block 121 has better gripping power and is relatively wear-resistant, can be used for a long time, and prolongs the service life of the roller. The bottom edge of the sawtooth triangular surface 121c extends toward the vertex of the adjacent sawtooth triangular surface 121c but does not approach, forming a sawtooth inclined triangular surface 121d. The distance gap between the bottom edge of the sawtooth inclined triangular surface 121d and the vertex of the sawtooth inclined triangular surface 121d enables the sawtooth block 121 to have better gripping power, and the distance gap from the vertex of the sawtooth inclined triangular surface 121d to the vertex of the sawtooth triangular surface 121c enables the sawtooth block 121 to have more wear space, thereby prolonging the service life of the roller.

[0024] In order to facilitate the processing and manufacturing, the number of sawtooth blocks 121 on each sawtooth ring 12 is the same. The sawtooth blocks 121 on each sawtooth ring 12 are arranged one by one, and the sawtooth triangular faces 121c on the correspondingly arranged sawtooth blocks 121 are on the same plane, and the sawtooth inclined triangular faces 121d are also on the same plane. There are two or more circles of sawtooth rings 12 on an inclined surface 11b. Preferably, there are three circles of sawtooth rings 12 on an inclined surface 11b. Preferably, there are four circles of sawtooth rings 12 on an inclined surface 11b.

[0025] A stepped serrated ring 12 is provided on the inclined surface 11b, and the serrated blocks 121 on the serrated ring 12 can increase the grip of the inclined surface 11b, prevent the wires or cables from slipping, and are not easy to wear; the serrated triangular surfaces 121c on the correspondingly arranged serrated blocks 121 are on the same plane, and the serrated inclined triangular surfaces 121d are also on the same plane, making processing more convenient.
