Tensioning device of conveyer belt of sealing machine

Abstract

The invention relates to a tensioning device of a conveyer belt of a sealing machine. The tensioning device comprises a tensioning wheel. The tensioning wheel is arranged on the inner side of the conveyer belt. The tensioning device additionally comprises a movable frame. The tensioning wheel is hinged to the movable frame through a pin roll. The movable frame is arranged on a support through a guide rail. The movable frame can slide along the guide rail. A raised part is formed on one side of the support towards the movable frame. An adjusting bolt penetrates through a hole in the movable frame and is connected with the raised part. The adjusting bolt is used for adjusting the position of the tensioning wheel, so that the tensioning extent of the conveyer belt can be adjusted and the demands for conveying different articles can be met; since a spring is arranged between the movable frame and the adjusting bolt, automatic tensioning can be realized and the relaxation of the conveyer belt due to deformation is compensated; since the conveyer belt has certain elasticity, the requirements for conveying different articles can be self-adapted within a certain range.

Description

technical field [0001] The invention relates to a conveyor belt tensioning device for a sealing machine, in particular to a conveyor belt tensioning device for a food packaging sealing machine, which belongs to the technical field of sealing machinery. Background technique [0002] The sealing machine is a machine that seals a container filled with packaging. After the product is loaded into the packaging container, in order to keep the product sealed and preserved, maintain product quality, and avoid product loss, it is necessary to seal the packaging container. This operation is in Finished on the sealer. To put it simply, a sealing machine refers to a machine that seals a container after it is filled with a product. In the food industry, the sealing machine is widely used. Usually, food is put into plastic bags or paper bags, etc., and then sealed with a sealing machine. The sealed food has a long storage time, is clean, and is easy to transport. [0003] Generally, the...

Problems solved by technology

The conveying device is mainly composed of a motor and a conveyor belt. The conveyor belt is generally equipped with a tensioning device to ensure the friction between the conveyor belt and the driving wheel, so as to ensure the normal operation of the conveyor belt. In addition, it can also compensate for the slack caused by the deformation of the conveyor belt. Existing The tensioning device generally uses the self-weight of the motor to achieve automatic tensioning. It has a defect that the belt after tensioning is small in elasticity, and it is easy to slip when transporting small food packaging bags, and it cannot be used when transporting different items. adjustment, adaptability
