Description

The rubber roller generally comprises an outer layer of rubber, a hard rubber layer, a metal core, a roller neck and a vent hole, and the processing comprises the working procedures of roller core sand blasting, bonding treatment, rubber coating forming, binding belt coating, vulcanizing in a vulcanizing tank, surface processing and the like. The rubber strip extruded by the rubber extruder is matched with a guide wheel of the gluing machine in the rubber coating forming process, and the rubber strip is extruded to a rotating workpiece through a rubber strip conveying mechanism, so that a workbench for providing the rubber strip moves along the axial direction of the workpiece, and the rubber strip is wound on the surface of the workpiece. Rubber roll production equipment on the market at the present stage has the following problems:
(1) the movement of the glue pressing rod on the workbench glue coating device is realized by the driving of the air cylinder. Due to the difference of the use requirements of various industries on the rubber roller, the diameter of the rubber covered on the rubber roller is within the range of 15 mm-1500 mm. If one glue coating machine is required to complete the production of rubber rollers with multiple specifications, an air cylinder with the stroke of at least 1000mm needs to be configured for the workbench, so that the length size of the glue coating device is larger than 1 meter, and the glue coating device is very inconvenient for a limited space on a walking workbench.
(2) When the workpiece rotates, the extruded adhesive tape is wound on the workpiece and moves along the axial direction of the workpiece, and the organic matching of the adhesive tape conveying speed, the workpiece rotating speed and the three movement speeds of the workbench moving along the axial direction of the workpiece is realized by completely depending on the experience and proficiency of operators and depending on human factors, so that certain difficulty exists in improving the efficiency and the quality.
(3) The rubber strip conveying process needs to pass through a series of guide wheels, the rubber strip needs to be tensioned by a tensioning wheel to ensure the rubber coating quality, the position of the tensioning wheel needs to be irregularly adjusted due to the change of the conveying speed of the rubber strip, the traditional adjustment mode depends on manual adjustment of a potentiometer, errors generated by manual operation are large, and the adjustment precision is difficult to ensure.
(4) The rubber covered by the rubber roller is immediately bound tightly by a temperature-resistant and pressure-resistant cloth belt on an original station after the rubber roller is wound and covered, so that the cross-linking reaction of the rubber in the vulcanization process is improved. The tightening force of the cloth belt is not detected, so that the hardness, density, strength, wear resistance and service life of vulcanized rubber can not reach the effect of a laboratory, and the service performance in actual production is influenced.
(5) The operating systems of the rubber roller winding covering machine which are commonly used at present mostly adopt a three-axis variable-frequency speed-regulating manual control system. When the workpiece rotates, the extruded adhesive tape is wound on the workpiece and moves along the axial direction of the workpiece, the matching of the speed of extruding the adhesive tape by the extruder, the rotating speed of the workpiece and the moving speed of the adhesive tape along the axial direction of the workpiece needs to be completely dependent on the experience and proficiency of operators, the influence of human factors is large, and certain difficulties exist in improving the efficiency and the quality.
