Description

Technical Field

[0001] The utility model relates to the technical field of tire manufacturing, in particular to an automatic tire hair trimming machine. Background Art

[0002] Tire vulcanization refers to putting semi-finished tires (green tires) into the mold of the vulcanizer for vulcanization and forming. In order to discharge the air in the semi-finished tires (green tires) during the vulcanization process, the mold is provided with exhaust holes. After the air is discharged, the rubber of the semi-finished tire is also discharged into the exhaust holes and connected to the tire, so that the tread (outer circle) and the sidewalls (both sides) of the vulcanized tire form rough rubber. The rough rubber seriously affects the driving performance and appearance of the tire, and the wear and tear during the driving of the tire causes the rough rubber to fall off, affecting the environment, so the rough rubber must be repaired and removed. The automatic tire rough rubber repair machine is a special production equipment that automatically removes the rough rubber of the tire after vulcanization according to the production process requirements during the tire manufacturing process. It is an indispensable and important process link in the tire production process. Specifically, most of the existing tire rough rubber repair machines are still manually operated or have a low degree of automation. The tire positioning and tightening precision is low, resulting in tire deformation and uneven roundness; the rough rubber repair is not thorough and the rough rubber repair knife cuts the tire surface, which obviously affects the quality of the tire and the low production efficiency of the equipment.

[0003] Chinese Patent 201711175580.8 A hair trimming mechanism, which drives the hair trimming assembly to rotate through a driving device until the end of the seat plate connected to the blade rotates to be opposite to the crown of the tire to be processed, and then the blade is driven to rotate relative to the seat plate through the telescopic movement of the first telescopic member, and finally the blade edge is opposite to the crown, so that the blade can cleanly trim the hair on the crown. When it is necessary to trim the hair on the shoulder, the hair trimming assembly can be driven to rotate again through the driving device until the end of the seat plate connected to the blade rotates to be opposite to the shoulder of the tire to be processed, and then the blade is driven to rotate relative to the seat plate through the telescopic movement of the first telescopic member, and finally the blade edge is opposite to the shoulder, so that the blade can cleanly trim the hair on the shoulder. The angle of the blade edge can be adjusted at any time through the first telescopic member to ensure that the blade edge can always cooperate with the surface of the tire to be processed, avoiding the situation where the hair trimming glue is not clean due to inappropriate blade angle. In addition, when the driving device drives the entire trimming assembly to rotate, the blade can be rotated to the crown position and the shoulder position, so that the rubber on the crown and shoulder can be trimmed more cleanly. However, this technology does not tighten the tire. When trimming, the blade is too deep to affect the tire surface, and too shallow to trim thoroughly.

[0004] The prior art uses 1-2 fixed wheels and 1-2 tensioning wheels to tighten the inner hole of the tire, which can reduce the deformation of the tire. At the same time, when the expansion and contraction cylinder is used for tightening, a pressure reducing valve is provided to control the expansion force. Although this technology uses a pressure reducing valve to adjust the pressure of the expansion and contraction cylinder to control the tension, it can only control the expansion force of the inner hole of the tire and cannot accurately position it. The prior art relies on the expansion force of the cylinder to control the expansion force of the inner hole of the tire, which will cause the tire to deform and become uneven, and the unevenness will cause the trimming glue to be incomplete, and the trimming glue knife will damage the tire surface. Therefore, the applicant hopes to seek a technical solution to improve this technical problem. Utility Model Content

A mechanism is provided for the three rubber trimming knives to automatically adjust the angles, of which one middle rubber trimming knife is used to trim the rubber in the middle area of ​​the tire tread, and the remaining one left rubber trimming knife and one right rubber trimming knife are used to trim the rubber in the left and right areas of the tire and the left and right side areas of the tire respectively. The three rubber trimming knives are designed to be attached to the tire surface for rubber trimming. The three rubber trimming knives are respectively driven by three cylinders, and the three cylinders are respectively connected to three precision pressure reducing valves. The three precision pressure reducing valves can respectively set pressures to control the pressure between the three rubber trimming knives and the tire surface. The knife automatically adjusts the angle according to the shape of the middle area of ​​the tire tread by the middle angle self-adjusting frame, and the other left rubber trimming knife and right rubber trimming knife automatically adjust the angle according to the shape of the left and right sides of the tire tread and the left and right sides by the left rubber trimming knife angle self-adjusting bracket and the right rubber trimming knife angle self-adjusting bracket, respectively.
