Description

Technical Field

[0001] The present application relates to the technical field of crimping devices, and in particular to a green tire crimping head device. Background Art

[0002] Tires are the components of a car that come into direct contact with the ground. Their performance directly affects the safety of the car. Tire crimping is a very important process in tire production. It involves crimping the joints at both ends of the flat raw tire material to form a cylindrical semi-finished product that is then transported to the subsequent process.

[0003] During the crimping process, existing tire crimping devices often use iron wheels to press the joints together. This method often results in a flat surface. However, the contour of the molded tire has a certain curvature. When the crimped green tire is formed, deformation of the green tire can cause the joint to crack, increasing rework and production costs. Therefore, the purpose of this application is to reduce the cracking of the crimped green tire.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection of this application.

[0024] As one of the embodiments of this application, please refer to Figure 1-3 As shown, the present application provides a green tire pressing joint device, which mainly includes: a support frame 1, a sliding frame 2 is provided on one side of the support frame 1, and a support column 3 is provided below the sliding frame 2; a driving device 4, which is movably arranged in the sliding frame 2, and the output end of the driving device 4 is directed downward; a pressing device 5, including a pressing wheel 51, a pressing shell 52, and a motor 53, the pressing wheel 51 and the support column 3 have a V-shaped profile, the pressing shell 52 is installed on the output end of the driving device 4, the pressing wheel 51 is rotatably arranged inside the pressing shell 52, and the shaft of the pressing wheel 51 is connected to the output shaft of the motor 53 arranged outside the pressing shell 52.

[0025] By fitting the two joints of the unformed green tire together and inserting the support column 3, adjusting the position of the driving device 4 to adapt to the corresponding tire, the driving device 4 moves the pressing device 5 downward, and the motor 53 starts to drive the pressing wheel 51 to rotate synchronously to complete the pressing operation on the green tire, and two contact points are generated between the V-shaped pressing wheel 51 and the support column 3, and a certain space is reserved between the center and the pressing wheel 51. The reserved space helps to additionally thicken the pressing point and further enhance the strength of the pressing joint.

[0026] As another embodiment of the present application, refer to Figure 1 、 Figure 4 、 Figure 5 As shown, the present application provides a green tire pressing joint device, which mainly includes: a support frame 1, a sliding frame 2 is provided on one side of the support frame 1, and a support column 3 is provided below the sliding frame 2; a driving device 4, which is movably arranged in the sliding frame 2, and the output end of the driving device 4 is directed downward; a pressing device 5, including a pressing wheel 51A, a pressing shell 52, and a motor 53, the contour of the pressing wheel 51A cooperating with the support column 3 is arc-shaped, the pressing shell 52 is installed on the output end of the driving device 4, the pressing wheel 51A is rotatably arranged inside the pressing shell 52, and the shaft of the pressing wheel 51A is connected to the output shaft of the motor 53 arranged outside the pressing shell 52.

[0027] By fitting the two joints of the unformed green tire together and inserting the support column 3, adjusting the position of the driving device 4 to adapt to the corresponding tire, the driving device 4 moves the pressing device 5 downward, and the motor 53 starts to drive the pressing wheel 51A to rotate synchronously to complete the pressing operation on the green tire.
