Novel rubber covered roller winding and surface-covering machine

Abstract

The invention particularly discloses a novel rubber covered roller winding and surface-covering machine which comprises a machine body; the machine body is provided with a workpiece fixing device; a rubber feeding machine, a feed extruder and a cooling device are arranged at one side of the machine body; the cooling device is connected with the feed extruder matched with the rubber feeding machine, so that rubber reaches the surface of a workpiece and then is wound; the rubber feeding machine is provided with an axial surface rubber covering device and an end surface rubber covering device, and mixed rubber can be used for continuously providing compact rubber bars with certain temperature through the feed extruder, so that a wound workpiece rotates; a working table for providing rubber bars moves along the wound workpiece; and the rubber bars are extruded to the wound workpiece through a rubber bar conveying mechanism. During the whole process, rubber bar rotation, moving and conveying are combined so as to finish the winding and surface covering processes of a rubber roller can be finished by organically combining the extrusion, the rotation, the moving and the rubber bar conveying.

Description

technical field [0001] The invention discloses a rubber roller wrapping machine, in particular a novel rubber roller wrapping machine. Background technique [0002] With the improvement of automation, many industries need to use rubber rollers. The speed of mechanical operation in these industries is getting faster and faster, and the requirements for rubber rollers are getting higher and higher. Of course, some automatic rubber roller winding and covering machines have appeared. But all there are various problems, there is following shortcoming in present rubber roller wrapping machine: [0003] (1) The rubber roller wrapping machine adopts hydraulic rolling coating. When the pressure of the oil cylinder is constant, it is difficult to use the increase of the rubber elastic body to give the oil cylinder a reaction force to move the oil cylinder backward and increase the pressure; [0004] (2) When the ambient temperature is high and high hardness compound rubber is ext...

AI Technical Summary

Problems solved by technology

[0003] (1) The rubber roller wrapping machine adopts hydraulic rolling coating. When the pressure of the oil cylinder is constant, it is difficult to use the increase of the rubber elastic body to give the oil cylinder a reaction force to move the oil cylinder backward and increase the pressure;

[0004] (2) When the ambient temperature is high and high hardness compound rubber is extruded, the temperature of the extruder will continue to rise with long-term continuous operation, and it is difficult to control the temperature at the required level by using conventional tap water cooling methods When some high-hardness mixed rubber meets the optimum extrusion temperature between 85-95 degrees Celsius, cooling with tap water at normal temperature is difficult to control, and a lot of water will be wasted;

[0005] (3) There are serious feeding problems when the compound rubber such as silicone rubber with high Mooney viscosity, poor self-adhesiveness and extremely poor strength

[0006] (4) The end surface of the workpiece cannot be glued. At present, the coating of the end surface of the rubber roller can only be done manually. First, it is time-consuming and laborious, and second, the yield is low.
