Description

TECHNICAL FIELD

[0001] The application relates to the field of tire butt joint technology, in particular to a novel electric knife structure. BACKGROUND

[0002] In the field of tire manufacturing, the processing of the tread is one of the key steps in the tire forming process. As the main component of the tire, the tread needs to be accurately cut and spliced after preliminary processing such as mixing and calendering to form a ring-shaped structure of the belt-shaped tire blank with a specific shape and size. The tread needs to be cut at both ends in the cutting stage, and the tread needs to be spliced after cutting to form a ring-shaped structure of the belt-shaped tire blank. This step is usually achieved by hot pressing technology, which uses high temperature and pressure to tightly combine the two sides of the tread to form a stable ring-shaped structure. The belt-shaped tire blank after hot pressing splicing has high strength and stability, and then enters the vulcanization process. The chemical reaction of the rubber in the tire blank during vulcanization converts it into a rubber product with elasticity and toughness. The vulcanized tire has the appearance, pattern, font and tread pattern of the finished tire, and has good use performance.

[0003] In the cutting of the tread, the current general method is manual cutting, but this method has the defects of uneven cutting surface and easy generation of burrs, and low efficiency. If a machine is used to cut automatically by an electric knife, the size of the blade of the electric knife is limited, and in the process of cutting the rubber strip from back to front, the temperature of the cut rubber strip is not uniform, which will cause inconsistent rubber strip butt joint effect in the subsequent butt joint of the tread end. If the electric knife is designed to be wider, the first cut rubber strip will be vulcanized due to long-term contact with high temperature, thereby affecting the quality and yield of the tire. Therefore, how to improve the uniformity of the temperature in the cutting process of the tread and improve the cutting and hot pressing efficiency has become a technical problem that needs to be solved by those skilled in the art. SUMMARY

[0006] A left splice plate and a right splice plate are provided above the two splice plates, and a clamping assembly for clamping the end of the tread is arranged on the two splice plates;

[0007] An electric cutter assembly is arranged between the left splice plate and the right splice plate, and the electric cutter assembly is connected with a cutting driving assembly.

[0010] Based on the above technical scheme, the heating block is additionally arranged at the rear end of the electric knife in the electric knife assembly, which provides a heat preservation effect for the strip interface after the cutting operation of the electric knife; the heating block can quickly and stably maintain a certain temperature of the rubber strip cutting area, so as to ensure that the strip interface will not affect the adhesion effect due to temperature drop before the rubber strip joint is processed; through this heat preservation mechanism, not only the adhesion strength between the rubber strip and the strip interface is enhanced, but also the stability of the overall structure is effectively improved, which lays a solid foundation for the subsequent rubber strip splicing work.

[0011] Preferably, the translation assembly for adjusting the distance between the left splicing plate and the right splicing plate is arranged, and the translation assembly is a linear driving structure.

[0015] Preferably, the cutting driving assembly further comprises a fourth air cylinder and a first guide rail arranged vertically, the lifting seat is vertically slidably connected with the first guide rail, and the air arm end of the fourth air cylinder is connected with the lifting seat.

[0016] Based on the above technical scheme, through the third cylinder and the fourth cylinder arranged in the longitudinal direction and the transverse direction respectively, the bidirectional control of the electric cutter assembly can be realized. The two cylinders cooperate to enable the electric cutter assembly to perform the action of descending cutting, and can also drive the electric cutter assembly to cut the rubber strip step by step along the width direction of the rubber strip, thereby improving the flexibility and accuracy of cutting, and greatly enhancing the automation level in the production process.

[0017] Preferably, the clamping assembly is composed of a clamping arm and a first cylinder mounted on the clamping arm, and the first cylinder is used to adjust the distance between the clamping arm and the spliced plate.

[0019] Based on the above technical scheme, the arm of the first cylinder can be driven to stably and reliably clamp the two ends of the rubber strip by using the clamping arm, the left spliced plate and the right spliced plate, which not only ensures that the rubber strip always maintains a stable state during cutting, avoids cutting errors caused by shaking or displacement, and greatly improves the accuracy of subsequent cutting operations.

[0020] In summary, the present application has the following beneficial technical effects:

[0021] 1. In the electric cutter assembly of the utility model, a heating block is additionally arranged at the rear end of the electric cutter, which provides heat preservation effect for the tire strip interface after cutting by the electric cutter, thereby increasing the bonding effect of the rubber strip joint and improving the splicing quality of the subsequent rubber strip.
