[0001] The utility model relates to the field of tire production equipment, in particular to a pressing device and a tire production system. Background Art

[0002] In the current production process of semi-steel tires, in order to meet the quality requirements of tires, manufacturers will require the joints at the end of the tire body to be pressed. At present, most of the stitching rollers arranged by various manufacturers are single stitching rollers to complete the pressing of the PA joints. However, with the advancement of technology and the improvement of product quality, in addition to the PA joints, the joints between the cords also need to be pressed.

[0003] The working principle of the existing single stitching roller during lamination is as follows: after the laminating drum is positioned at an angle, the stitching roller is driven by a cylinder to move along the radial direction of the laminating drum to press the material head. The laminating drum needs to be positioned three times and the roller needs to be reciprocated for three times to complete the lamination of the entire joint. Therefore, there is a problem of long lamination time, which cannot meet the efficiency of tire production.

[0004] Therefore, there are problems in the prior art such as long pressing time of the pressing rollers and low efficiency. Utility Model Content

[0005] The main purpose of the utility model is to provide a laminating device and a tire production system to solve the problems of long laminating time and low efficiency of the pressure rollers in the prior art.

[0029] When the lamination device in the present application is used, since the lamination device has a first pressing roller assembly 10, a second pressing roller assembly 20 and a third pressing roller assembly 30, the tire bead can be pressed from three different directions by the first pressing roller assembly 10, the second pressing roller assembly 20 and the third pressing roller assembly 30. In other words, the PA joint of the tire bead and the cord fabrics can be pressed from the front, back and top positions by the first pressing roller assembly 10, the second pressing roller assembly 20 and the third pressing roller assembly 30, thereby improving the lamination efficiency. Therefore, the lamination device in the present application effectively solves the problem of long pressing time and low efficiency of the pressing rollers in the prior art.

[0030] In a specific embodiment of the present application, the laminating device further includes a frame 40, and the first pressing roller assembly 10 and the second pressing roller assembly 20 are respectively arranged on the frame 40. Preferably, the first pressing roller assembly 10 and the second pressing roller assembly 20 are symmetrically arranged on both sides of the frame 40. That is, in this embodiment, the first pressing roller assembly 10 and the second pressing roller assembly 20 are symmetrically arranged at both ends of the length direction of the frame 40.

[0031] Specifically, the pressing device further includes a bracket 50 , which is disposed on one side of the frame body 40 in the width direction, and the third pressing roller assembly 30 is disposed on the bracket 50 .

[0032] Preferably, the bracket 50 is arranged along the vertical direction.

When the suction cup of the tire bead transfer ring is adsorbed to the tire bead, the first pressure roller assembly 10 and the second pressure roller assembly 20 are extended to the diameter range of the corresponding inch level through the action of the large cylinder, and then the right tire bead transfer ring carries the tire bead to the waiting position. After the inner liner and the sidewall are attached to the forming drum, the forming drum is immediately moved horizontally to the upper ring position. At the same time as this action, the first pressure roller assembly 10 and the second pressure roller assembly 20 are extended and pressed to the joint under the action of the small cylinder. As the forming drum moves, the first pressure roller assembly 10 and the second pressure roller assembly 20 rotate around their own internal rotating shafts, thereby achieving the purpose of the first pressure roller assembly 10 and the second pressure roller assembly 20 pressing the joint.
