Description

Technical Field

[0001] The utility model belongs to the field of belt processing equipment, and in particular relates to a belt connection mold and a hot press comprising the mold. Background Art

[0002] A belt is a mechanical transmission device that transmits motion and power through friction. It is widely used in various mechanical equipment such as automobiles, robots, and transmission machinery. Some belt products have guide strips on the inside, which prevent the belt from running off the track and increase friction. For the processing of the guide strips, the belt is usually flipped over to expose the inside of the belt for easy processing, and then the guide strips are welded to the inside of the belt, and finally the inside of the belt is flipped over to restore. However, in actual production and processing, this method is not suitable for processing some small belts, which need to meet certain conditions. The circumference of the belt loop must not be less than 4 times its width, otherwise the inside of the belt is difficult to flip out for processing the guide strips. Even if it is forcibly flipped, it will leave creases and damage that are difficult to recover.

[0003] Faced with this situation, the existing technology solution is to first unfold the inner side of the semi-finished bottom belt of the belt product and open the teeth, weld the guide bar to the inner side of the belt, and reserve a space for the guide bar at the belt joint (toothed part). After the production workers use the belt hot press to connect the belts, they manually weld the guide bar at the joint. This existing technology has the following disadvantages: First, the finished belts produced by this technology are of poor quality and the guide bar is not firm; second, the guide bar at the joint must be manually welded, the cost of training skilled workers is high, and it is difficult to ensure neatness and unsightly; third, the production efficiency is low. Utility Model Content
