Problems solved by technology

The extrusion linkage production line occupies a large area, and the process route is complicated. Each process has a certain impact on the final molding compound, and the product uniformity is difficult to guarantee.
The ring is formed through the end-to-end joint, and the material at the joint is more or less uneven, which greatly reduces the uniformity of the tire's dynamic balance. In addition, if the fit is not firm, it is easy to produce air bubble interlayers and reduce the strength of the tire tread.
As can be seen from the above, the uniformity of tires produced by existing tire production equipment is relatively poor

Abstract

The invention provides a tire production device including: a moulding drum (10), which is provided with an annular moulding surface (11). The moulding drum is arranged in a pivot manner, wherein a pivot axial line of the moulding drum (10) is coincided with the axial line of the annular moulding surface (11) and is extended in a horizontal first direction. The tire production device also includes a rubber supply apparatus (100), which includes: a rubber supply extruder (20) comprising a rubber material inlet (21) and a rubber strip extrusion outlet (22); a pressing mechanism (30) including a pressing part (31) which has a pressing status in which a rubber strip extruded from the rubber strip extrusion outlet (22) is pressed onto the annular moulding surface (11) and a de-pressing status in which the pressing part (31) is far away from the annular moulding surface (11). The rubber supply extruder (20) includes a melt metering pump (23), which is arranged at the rubber strip extrusion outlet (22). The tire production device improves uniformity of tires.

Description

technical field [0001] The invention relates to the technical field of tire production, in particular to a tire production equipment. Background technique [0002] The dynamic balance and uniformity of the tire are directly related to the driving stability, safety and energy saving of the car. With the rapid development of the automobile industry, higher requirements are put forward for performance indicators such as tire dynamic balance and uniformity. [0003] The current manufacturing process of tires is that the sidewall and tread are prefabricated and cooled for later use. When the tire is formed, the prefabricated cold tread is cold-pasted on the forming machine for head-to-tail butt joint. The disadvantage is that the material at the joint is more or less uneven. Greatly reduce the uniformity of tire dynamic balance, and in addition, if the bonding is not firm, air bubble interlayers will easily occur and the strength of the tire tread will be reduced. [0004] In t...
