Description

Technical Field

[0001] The utility model relates to the technical field of wire and cable manufacturing, in particular to a conductor roller. Background Art

[0002] In the field of wire and cable production, due to site limitations or special requirements of the production line, the production line of wire and cable will not be a straight line. It usually needs to go through multiple changes of direction to change the direction of travel of the wire and cable, and use different equipment to complete different production processes. With the advancement of technology, the production of wire and cable is becoming more and more efficient and high-speed. The production line speed of some processes of wire and cable exceeds 1500 meters / minute. Ordinary wire rollers are commonly made of various metals, plastics, etc. For example, CN202130827U discloses a new type of lightweight unpowered roller, which has a cylinder body, a PVC cylinder body is arranged in the cylinder body, and a rolling bearing is arranged in the PVC cylinder body. The cylinder body is made of thin-walled SUS304 stainless steel pipe.

[0003] When high-speed wires and cables pass over the surface of ordinary wire rollers, friction is generated, causing the surface of the ordinary wire rollers to wear. When the wear depth reaches a certain depth, the grooves worn out will cause scratches on the surface of the wires and cables, thereby causing the produced wire and cable products to fail to meet product quality requirements. For this reason, maintenance personnel are required to regularly inspect the wire rollers, which results in a large maintenance workload. Utility Model Content

[0004] In view of this, the utility model proposes a wire roller, which arranges a ceramic layer on the outer wall of the cylinder, so as to improve the wear resistance of the wire roller through the ceramic layer and increase the service life of the wire roller, thereby effectively reducing the maintenance frequency and reducing the workload of maintenance personnel, solving the problem that the existing wire roller requires frequent maintenance during use and has a large maintenance workload.

DETAILED DESCRIPTION

[0038] The following will be combined with the specific embodiments of the present invention to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] like Figure 1-7 As shown, a conductor drum of the present invention comprises a central shaft 1 and a cylinder body 2.

[0040] Among them, the cylinder 2 is made of metal or hard plastic material, and is rotatably arranged on the central axis 1 through a bearing. A ceramic layer 201 is provided on the outer wall of the cylinder 2. The ceramic layer 201 is used to enhance the wear resistance of the wire drum and improve the service life of the wire drum, thereby effectively reducing the maintenance frequency and reducing the workload of maintenance personnel.

[0041] The ceramic layer 201 is cylindrical, and the outer surface of the cylindrical ceramic layer 201 is smooth, and the inner surface of the cylindrical layer is evenly distributed with a number of grooves 20101 for filling structural adhesive. When installed, the ceramic layer 201 is coaxially sleeved on the cylinder 2. The wall thickness of the cylindrical ceramic layer 201 is 4-5 mm, and the outer diameter of the cylinder 2 is 3-4 mm smaller than the inner diameter of the ceramic layer 201. When installed, a gap 202 filled with adhesive will be formed between the ceramic layer 201 and the cylinder 2. Figure 1 As shown, the glue-filled gap 202 is used to fill with structural glue, and the ceramic layer 201 is fixedly connected to the cylinder 2 by the structural glue. After installation, the outer cylinder surface of the ceramic layer 201 is used to fit the outer surface of the cable, that is, during the transmission of the wire, the side surface of the wire is in contact with the outer cylinder surface of the ceramic layer 201.

[0042] like Figure 3 As shown, a groove 203 is provided on the outer wall of the cylinder 2, and the groove 203 is used to fill the structural adhesive. Through this structure, the structural strength of the structural adhesive after curing can be improved, thereby improving the firmness of the ceramic layer 201 after pasting. The groove 203 is a spiral groove or an annular groove. When the groove 203 is an annular groove, the groove 203 is provided with a plurality of axial intervals along the cylinder 2, such as Figure 5As shown, when the groove 203 is a spiral groove, both ends of the spiral groove extend to both ends of the cylinder 2. When injecting glue, the glue is injected from one end of the spiral groove, which makes it easier to fill the glue filling gap 202 with structural glue and facilitates glue injection.

[0043] In addition, there are two bearing mounting positions on the cylinder 2 for fixing the outer ring of the bearing, specifically, Figure 3 As shown, the cylinder 2 has a center hole 205, and bearing mounting holes 206 are provided on both ends of the center hole 205. The inner diameter of the bearing mounting hole 206 is larger than the inner diameter of the center hole 205, wherein the bearing mounting hole 206 is a bearing mounting position, and its inner side is used to fix the bearing.

[0044] To match the installation of the bearing, such as Figure 2 As shown, two bearing mounting portions 104 are provided at positions corresponding to the bearing mounting holes 206 on the central shaft 1 , and the bearing mounting portions 104 are used to fix the inner ring of the bearing, wherein the outer diameter of the bearing mounting portion 104 is larger than the diameter of the central shaft 1 .

[0045] In addition, to prevent the bearing from falling off, Figure 2 As shown, a retaining spring installation groove 103 is provided on one end of the central shaft 1 away from the installation flange 101. The retaining spring installation groove 103 is used to clamp the retaining spring, which limits the bearing to prevent it from falling off.

[0046] In the above-mentioned wire drum, one end of the central axis 1 is rotatably arranged inside the cylinder 2 through a ball bearing, and a mounting flange 101 is provided on the other end, wherein the diameter of the mounting flange 101 is equal to the outer diameter of the ceramic layer 201, and a screw mounting hole 102 is provided on the end of the mounting flange 101 away from the cylinder 2. When installing the wire drum, the mounting flange 101 is placed on the mounting surface, and then a screw is screwed into the screw mounting hole 102 to fix the wire drum to the mounting surface by the screw.

[0047] like Figure 1 As shown, one end of the cylinder 2 is aligned with one end of the ceramic layer 201, and a limiting flange 204 is provided on the other end, wherein the diameter of the limiting flange 204 is less than or equal to the outer diameter of the ceramic layer 201, and one end of the ceramic layer 201 and one end of the limiting flange 204 are abutted against each other, and one end of the glue filling gap 202 is closed by the abutting structure, which facilitates the restraint of the structural glue through the structure. When injecting glue, the structural glue is not easy to leak, which facilitates the installation of the ceramic layer 201.

[0048] In the above structure, the structural adhesive is a soft structural adhesive. After solidification, it has a certain elasticity and can play a good buffering role to prevent the cylindrical ceramic layer 201 from being broken by external impact.

[0049] The method of using a wire roller of the utility model is as follows:

[0050] First, the mounting flange 101 is placed on the mounting surface, and then screws are screwed into the screw mounting holes 102 to fix the mounting flange 101 to the mounting surface, thereby achieving the installation and fixation of the wire roller. When conveying the wire, the wire passes through the side of the cylindrical ceramic layer 201.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
