Self-adapting baffle plate assembly for tunnel type sterilization drier

Abstract

The invention discloses a self-adapting baffle plate assembly for a tunnel type sterilization drier, which comprises a baffle plate and an opening and closing mechanism of the baffle plate, wherein the opening and closing mechanism of the baffle plate is installed on an outer side plate of a box body, the baffle plate is connected with a self-adapting regulation mechanism, the self-adapting regulation mechanism comprises a compression bar, a roller and a compression spring, the middle section of the compression bar is connected with a supporting point and can rotate around the supporting point, the roller is connected with one end of the compression bar by a rolling shaft and contacts with the baffle plate, and the compression spring is arranged between the other end of the compression bar and the outer side plate of the box body. The invention is the self-adapting baffle plate assembly used for the tunnel type sterilization drier, which has simple and compact structure, low cost, convenient operation and good reliability and can carry out self-adapting regulation according to thermal expansion and cold contraction.

Description

technical field [0001] The invention mainly relates to the field of food and medicine packaging equipment, in particular to a tunnel type sterilization dryer. Background technique [0002] In the food, pharmaceutical and other packaging machinery industries, the tunnel sterilization dryer is divided into a preheating section, a heating section and a cooling section, and is mainly used to complete the drying, sterilization and depyrogenation of medicine bottles and the cooling process. The above-mentioned sections carry different processes. The tunnel-type sterilizing dryer feeds bottles continuously, and the conveying mesh belt passes through each section. The inlet and outlet are reserved between each section, and at the same time, the air in each section cannot flow through each other excessively. The temperature of the circulating hot air in the oven in the heating section reaches 300-350°C. If a large amount of hot air flows to the preheating section or the cooling secti...

Problems solved by technology

Usually, a rack is installed on the partition, and a gear is installed on the driving shaft. The gear drives the rack to adjust up and down. However, the coordination between the gear and the rack requires high precision, and the adjustment of the center distance is small. Because the oven in the heating section is heating Finally, under the influence of thermal expansion and contraction, the side of the box body is elongated and deformed outwards, and the deformation amount is 2-6mm, and the partition plate fixed on the box body is also deformed outwards, resulting in the change of the center distance between the gear and the rack. Small, stuck in severe cases, so that it cannot be adjusted
