Production method of chain tightness adjusting device for PVC glove production line

- Jun 11, 2019-

Background technology:

PVC gloves are made of PVC paste resin, plasticizer, debonding agent, heat stabilizer, colorant and filling.the gloves are of good anti-static property and suitable for semiconductor processing, food processing, sales and other industries.The transmission of PVC glove production line mainly relies on the chain. As PVC gloves need to be heated up and cooled down during production, the chain will be too loose to cause the phenomenon of trucks, and the chain will be too tight to cause the fracture phenomenon during cooling, which seriously affects the normal operation of PVC glove production line and reduces the production efficiency.

Technical implementation elements:

The utility model aims to solve the existing technology of PVC gloves production line of the chain is affected by the heating and cooling, it's easy to have a loose trucks and too close fracture defects, provide a PVC gloves production line with the chain elastic adjusting device, the cooling process of heating in the chain of adjusted firmness, avoid trucks and cooling heating when the chain too loose chain is too tight to cause fracture phenomenon in the process, to ensure the normal operation of PVC gloves production line.

The utility model is realized through the following technical scheme:

Is a kind of PVC gloves production line with the chain elastic adjusting device, including the chain wheel, the ends of the chain wheel spindle is equipped with the chain wheel, its characteristic is to include the chain wheel spindle is equipped with square fixed frame, the activities of the fixed frame inside a square square frame, equipped with roller on the bottom of the activity framework, fixed frame has to match the roller track, activities at both ends of the frame respectively through bearing and chain wheel shaft connection, activity framework backend with screw, screw for two, left and right sides of each one, the outer end of the screw through the external fixed framework extends to the fixed frame, screw and a fixed frame joint has a nut.

The lead screw of the utility model is one on each side, and the roller and track are installed symmetrically on both sides. When adjusting the lead screw, the length of both sides should be the same to prevent the chain from running off and ensure smooth operation.

The principle of the utility model is as follows:

By turning the nut fixed on the fixed frame and the lead screw with a special wrench, the movable frame and chain wheel are driven to move left and right on the track, and the chain also expands and contracts with the left and right movement of the chain wheel, so as to achieve the purpose of adjusting the tightness.

The utility model has the advantages of reasonable structure, flexible and convenient use.By using the utility model, the tightness of the chain can be adjusted quickly and efficiently, and the phenomenon of rupture caused by excessive tightness of the chain during the heating process of truck and cooling process can be avoided, so as to ensure the normal operation of PVC glove production line.
