Discharge gate mechanism

Abstract

The invention relates to a discharge gate mechanism. The mechanism comprises a discharge gate which rests against a discharge hopper port inside a discharge bin, a coupler, an L-shaped connecting lever, an axial supporting device of the L-shaped connecting lever, a drive unit of the L-shaped connecting lever and a sealing member for sealing a connecting part of the parts; the coupler consists of a pin boss and a pin inserted into the same, and is externally provided with a matching sealing rubber sleeve; one arm of the L-shaped connecting lever is connected with the discharge gate by the coupler, and the other arm is provided with a stepped section which hermetically passes through a discharge bin shell and is connected with the drive unit, and the stepped section is sequentially sheathed with a sealing rubber cup, a supporting casing and a retaining ring of the axial supporting device; the sealing rubber cup, the supporting casing and the retaining ring are arranged inside a supporting sleeve, one end of the supporting sleeve is fixedly arranged outside the discharge bin shell, and the other end of the supporting sleeve is fixedly connected with the drive unit; and a sealing ring is arranged between the supporting casing and the supporting sleeve. The discharge gate mechanism has the advantages of good tightness, convenient opening and closing and easy assembly and disassembly for cleaning.

Description

technical field [0001] The invention relates to a material discharging door mechanism. Background technique [0002] Medicine, food, etc. are related to the safety of human life. Therefore, the country has extremely strict hygienic requirements for products in the medicine and food industries, and regular or irregular spot checks and testing are required for the production environment, production equipment, material hygiene conditions and products. To ensure product safety, no harm to human consumption.

[0003] At present, in some pharmaceutical and food production equipment, the unloading door mechanism of the necessary unloading cabin usually adopts a large ball valve or a butterfly valve, which has poor sealing performance, easily enters dust, generates pollution, and causes material denaturation. It is beneficial to the transportation, production and storage of materials with high sealing requirements such as powder and granular materials, which will easily lead to waste of production materials and decrease in production efficiency; and due to the heavy weight of ball valves or butterfly valves, it is not conducive to control and brings a lot of inconvenience to production.
