Filter element drying tunnel improved device of filter

Abstract

The invention discloses an improved device of a baking channel used in the production process of an automobile filter core, comprising a heating baking box (2) and a conveying chain (3) with metal pieces connected in series in the interior in order to pass through the whole inlet and outlet; the external ring of the conveying chain (3) is circularly provided with a group along the length direction, namely two supporting cushions (4) with mutual distance more than the diameter of a central bulge of an end cover (1b) and less than the diameter of the external ring of an end cover (1b); the length of the supporting cushion (4) is not less than that of the central bulge of the end cover (1b). The supporting cushion (4) is a long strip-shaped steel wire spiral spring end to end. When paper core inserted into the glued end cover (1b) is sent to the baking box (2), the bulge section of the end cover (1b) is arranged on the two supporting cushions (4) of the conveying chain, thus enlarging the mutual contact area, reinforcing the stability of the operation of the conveying chain (3), reducing the side turnover of the filter core (1) in the baking passage, and improving the product quality in process.

Description

technical field [0001] The invention relates to an improved device for manufacturing equipment of auto parts, in particular to an improved device for using a drying tunnel in the production process of an auto filter element. Background technique [0002] As we all know, an important part in the middle of the car filter is the filter element. The filter element is made of filter paper folded into a chrysanthemum-shaped annular cylindrical paper filter element with a certain height, and then the paper filter element is glued to two disc-shaped end caps at both ends by glue. In the process, the glue is cured through the drying tunnel, and the paper filter element is firmly bonded with the end covers on both sides to form a filter element component. [0003] The end caps at both ends of the filter element are generally flat end caps at one end, and a cylindrical pipe section protruding outward from the center at one end, so that parts such as check valves can be assembled on the...

Problems solved by technology

This patent is mainly to adjust the horizontal position of the conveyor belt, and cannot solve the problem of vibration and bumps during the conveying operation of the conveyor belt in the form of metal sheets connected in series

[0007] After searching, at present, domestic and foreign filter element heating and curing ovens all use metal sheets in series with the conveyor chain structure, and both have the same adverse consequences. The applicant for this patent is a Sino-foreign joint venture professional enterprise. It is known that there are similar problems in foreign countries. Disadvantages
