Description

Technical Field

[0001] The invention relates to the technical field of transmission equipment, in particular to a belt pressing device for preventing the fluttering belt of a belt conveyor. Background Art

[0002] Belt conveyor, also known as rubber belt conveyor, is widely used in household appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, food and other industries, assembly, testing, debugging, packaging and transportation of objects, etc. Line conveying can adopt various control methods such as ordinary continuous operation, beat operation, variable speed operation, etc. according to process requirements; the line body can be selected according to local conditions: straight line, curve, slope and other line forms, conveying equipment including belt conveyor, also called belt conveyor or rubber belt conveyor, etc., is an indispensable economical logistics conveying equipment for rhythmic assembly lines. Belt conveyors can be divided into heavy-duty belt conveyors such as mining belt conveyors and light-duty belt conveyors such as those used in electronic plastics, food and light industry, chemical and pharmaceutical industries according to their conveying capacity.

[0003] During the use of existing conveyors, the belt and the roller may slip when they are in operation for a long time. The contact between the belt and the roller is mainly achieved through the friction between the belt's own gravity and the roller to achieve the transportation of surface objects and the transmission of power. At the same time, the friction is mainly adjusted by the internal tensioning device to increase the pressure between the belt and the roller, thereby preventing the occurrence of streamers. However, this adjustment method will increase the pressure inside the belt. Long-term tensioning will cause cracks on the surface and inside of the belt, reducing the service life of the belt. At the same time, placing transported items on the surface of the belt after it is tightened will further increase the bearing capacity of the belt and increase the workload of the belt. If the belt is loosened, it will cause the belt to float due to the centrifugal force when it is rotating and no items are placed. For this reason, we propose a belt pressing device for preventing streamers in belt conveyors. Summary of the invention

[0033] A pressing component 3, which is arranged on the side of the transmission component 2, and the bottom end of the pressing component 3 is in contact with the ground;

[0034] The limiting component 4 is arranged on one side of the pressing component 3. The pressing component 3 can be used to limit the top of the crawler 7, and the limiting component 4 can be used to limit the two sides of the crawler 7.

[0035] The pressing component 3 includes a base 9, and a base 9 is provided on the side of the transmission component 2. The top of the base 9 is fixedly connected to a support frame 10, and the internal rotation of the support frame 10 is connected to a transmission shaft 11, and the outer edge of the transmission shaft 11 is fixedly connected to a shell 12, and the outer edge of the shell 12 is slidably connected to an inner shaft 13, and one end of the inner shaft 13 is provided with a plurality of groups of fixing holes 14, and the internal rotation of the fixing hole 14 is connected with a fixing bolt 15.
