Degreasing mesh belt automatic tensioning structure for continuous degreasing sintering furnace

Abstract

The invention discloses an automatic degreasing mesh belt tensioning structure for a continuous degreasing sintering furnace, which relates to the technical field of tensioning structures and comprises a first smooth roller, an internal rocker arm, a second smooth roller and an elastic mechanism. The first smooth roller is rotatably arranged below the degreasing mesh belt, and one end of the internal rocker arm is connected with a rotating shaft of the first smooth roller; the other end of the internal rocker arm is connected with a rotating shaft of the second smooth roller; one end of the elastic mechanism is fixed to a box body of the continuous degreasing sintering furnace, and the other end of the elastic mechanism is connected with a rotating shaft of the first smooth roller. The automatic tensioning structure can ensure that the degreasing mesh belt is always in a tensioned state when the temperature is increased, so that the mesh belt runs stably; and when the temperature is reduced to the cold state, the equipment is recovered to the original state. The tensioning spring is located outside the box body, and the tensioning force on the mesh belt can be adjusted at any time. And a mesh belt tensioning stop rod and a mesh belt tensioning rocker arm limiting rod are arranged outside the box body to control the motion amplitude of the internal tensioning roller.

Description

technical field [0001] The invention relates to the technical field of tensioning structures, in particular to an automatic tensioning structure of a degreasing mesh belt used in a continuous degreasing sintering furnace. Background technique [0002] The continuous degreasing sintering furnace is one of the main equipment for firing metal injection molding (MIM) process products at present. The smoothness of the continuous degreasing and sintering furnace operation plays a vital role in product quality and production efficiency. During the production process, the main parts where the running stability problem will occur are the degreasing section, the transverse transportation section and the sintering section. Among them, the main reason for the unstable operation of the mesh belt in the degreasing section is that when the furnace body heats up, the length of the mesh belt increases, the operation becomes loose, the number of meshes between the driving roller rack and the...

Among them, the main reason for the unstable operation of the mesh belt in the degreasing section is that when the furnace body heats up, the length of the mesh belt increases, the operation becomes loose, the number of meshes between the driving roller rack and the mesh belt decreases, and the mesh belt skips teeth and the boat jams. As a result, the operation of the material boat is unstable, the product is displaced in the material boat, and the surface is cracked or even broken, which affects the yield of product production
