Movable door structure of box type furnace

Abstract

The invention relates to a movable door structure of a box type furnace, which belongs to the technical field of the electronic products of sintering kilns. The box type furnace comprises a furnace body. A movable door mechanism comprises a movable portal, a driven carriage, a driving carriage, a movable door, a power transmission device, a first locking device and a second locking device, wherein the movable portal is configured at one side of the length direction of the furnace body, the upper part at the length direction of the movable portal is fixedly provided with a pair of upper guide rails, and the lower part is fixedly provided with a pair of lower guide rails; each pivot at both ends of the length direction of the driven carriage is provided with a pair of upper rollers; both ends of the length direction of the driving carriage are respectively pivoted and provided with a pair of lower rollers; the upper edge of the movable door is connected with the driven carriage, the lower edge is connected with the driving carriage, a sealing strip groove is concavely arranged on the movable door, and a sealing strip is embedded and arranged in the groove; the power transmission device is arranged on the driving carriage and is connected with the driving carriage in a transmission way; and the first locking device and the second locking device are respectively arranged on the driven carriage and the driving carriage. The opening or the closing of the movable door is labor-saving, quick and convenient, and the labor strength of an operator is lowered; and the invention is beneficial to saving energy and guaranteeing the quality of a product in the furnace.

Description

technical field [0001] The invention belongs to the technical field of sintering kilns for electronic products, and in particular relates to a sliding door structure of a box-type furnace. Background technique [0002] People are used to calling the sintering kiln for electronic products whose appearance and shape resembles the shape of a box as a box furnace. Box-type furnaces are widely used in the production process of electronic products, such as ceramic capacitor piezoelectric transducers, ceramic filters and ceramic thermistor elements, etc., which are fed into the box-type furnace after batching, mixing and tableting For sintering, the box furnace is usually equipped with a furnace door for charging, discharging, cleaning and maintenance of the furnace. [0003] In the prior art, the furnace door structure equipped on the box furnace mainly includes the following two types: one is to use a hinge (hinge) to hinge the furnace door to one side of the furnace entrance an...

Problems solved by technology

However, the sliding door structure still has the following disadvantages: the one is that the opening and closing of the door body are all manually operated, so it does not have the advantages of lightness and labor-saving; Satisfactory degree, the heat in the furnace is easy to escape from the gap between the door body and the furnace body, resulting in energy waste, especially when the sintering is completed and the temperature is lowered, once the outside air enters the furnace, the product will be oxidized and the quality will be affected

[0004] The applicant has searched the literature, no matter whether it is patent literature or non-patent literature, there is no technical revelation that can make up for the lack of the aforementioned sliding door structure, and there is no report of successful application in the industry.
