Description

Novel compaction device for tire seams

Technical Field

The utility model belongs to the technical field of tire production corollary equipment, concretely relates to a novel compaction device that is arranged in tire production line tire concatenation seam.

Background

Currently, rubber tires are produced by extruding the tread of the tire in a planar manner by a tread extrusion device, and then performing final molding through cutting, butting, and the like.

When the tires of the farm tool cart are produced, because the production standards and requirements of the tires are far lower than those of automobile tires due to the influence of the use environment, the splicing seams of the tires are compacted at high pressure by using compacting equipment in the tire butt joint process.

The existing compaction equipment mostly utilizes an oil cylinder or an air cylinder to push a compaction roller, so that the compaction roller is aligned to a splicing seam of a tire to carry out reciprocating rolling compaction. However, the compacting method has certain disadvantages after long-term use, and because the tire is clamped between the upper compacting roller and the lower compacting roller in the compacting process of the compacting roller, the tire is always in point contact and does reciprocating motion, even if the tire has certain toughness, the shape of the tire can be twisted under reciprocating high-pressure rolling compaction. After the customer reaction is applied to the vehicle at a later stage, even if the running speed of the tire is not high, the dynamic balance of the tire may be changed when affected by the external environment or the high-load use state, and the tire may be damaged when serious.

Secondly, the reciprocating rotation of the compaction roller is driven by a motor, the length of the splicing seam of the tire is limited, the motor needs to perform repeated short-distance reciprocating switching in a short time, so that the performance requirement on the motor is high, and the related electric control system is also needed to be matched for operation, so that the inconvenience and the cost of later maintenance are increased.

Thirdly, the existing compaction effect also has certain defects, because the compaction roller rolls and compacts the splicing seam, the contact surface is always point contact, even if the roller rolls repeatedly, the compaction duration and the compaction effect are limited, and finally the splicing quality is also influenced. Moreover, under the influence of the thickness of the tire tread (the tire tread is in direct contact with the ground, so the thickness is large, and the tire side wall is not in contact with the ground, so the thickness is thin), the height of the splicing seam is not completely consistent but is changed along with the thickness change of the tire side wall and the tire tread, and when the compaction roller touches the height difference between the tire tread and the tire side wall, larger impact force can be generated, so that the compaction quality is influenced by uneven stress. And although other special compaction equipment has good compaction effect, the structure of the special compaction equipment is too complex, each production line needs to be purchased, the cost is high, the product price is high, the market competitiveness of the product is low, and the principle is also a physical compaction mode.

Therefore, it is necessary to provide a device for compacting in a surface contact manner to improve the quality of tire splicing, the effect of later application, and the safety.
