This patent is of great significance. The patent abstract shows that the present invention relates to the technical field of forming machines. A disclosed forming machine for tire production includes a base on which a belt transfer ring, a forming drum and a conveyor belt are arranged.
There is a first motor on the inner wall of the base to drive the adjustment plate to move. There is an installation bracket on the bottom installation box of the adjustment plate. The first cylinder in the installation bracket can adjust the attitude of the laser displacement sensor. It is equipped with a laser alignment detection device to achieve real-time and accurate detection of the belt layer joint fitting position and angular deviation.
The second motor on the installation box drives the belt drum to run, and the second cylinder in the installation box drives the lifting block to adjust vertically. The third cylinder cooperates with the connecting frame, slide block, slide rail and other structures to link the support plate, connecting plate and connecting seat to complete multi-angle and multi-directional posture fine-tuning.
Each structure is coordinated and linked, eliminating the need for manual calibration of the joint fitting angle, improving accuracy and consistency, adapting to the production of tires of different specifications, and improving molding quality and production stability.
