Manufacturing method of chain tension regulator for PVC glove production line

- Dec 31, 2020-

Background technique:


PVC gloves are glove products produced with polyvinyl chloride as the main raw material. The main raw materials used are PVC paste resin, plasticizers, viscosity reducers, heat stabilizers, colorants and fillers, etc. The gloves made of gloves have good antistatic properties , Suitable for semiconductor processing, food processing, sales and other industries. The transmission of the PVC glove production line mainly relies on chains. As PVC gloves need to be heated and cooled during production, the chain will be too loose and cause trucks when the temperature is raised. When the temperature is reduced, the chain will be too tight and cause breakage, which seriously affects the PVC glove production line The normal operation of the system reduces production efficiency.

PVC nitrile glove dipping machine

Technical realization elements:


The purpose of the utility model is to solve the problem that the chain of the PVC glove production line in the prior art is affected by heating and cooling, and is prone to over-loose trucks and over-tight breaks. It provides a chain tension adjustment device for the PVC glove production line, which is in the heating and cooling process. Adjust the tightness of the chain in the middle to avoid the phenomenon that the chain is too loose when the temperature rises and the chain is too tight and the chain is too tight during the cooling process to break, and to ensure the normal operation of the PVC glove production line.


The utility model is realized through the following technical solutions:


That is, a chain tension adjustment device for a PVC glove production line, which includes a chain wheel shaft. The two ends of the chain wheel shaft are provided with chain wheels. It is characterized in that a square fixed frame is provided at the chain wheel shaft and a square movable frame is arranged inside the square fixed frame. Frame, the bottom of the movable frame is provided with rollers, the fixed frame is provided with a track matching the rollers, the two ends of the movable frame are respectively connected with the chain axle through the bearing seat, the rear end of the movable frame is provided with lead screws, two lead screws , One on each of the left and right sides, the outer end of the lead screw extends through the fixed frame to the outside of the fixed frame, and a nut is provided at the connection between the lead screw and the fixed frame.


The lead screw of the utility model has one on the left and right sides, and the roller and the track are also installed symmetrically on the left and right sides. When the lead screw is adjusted, the length of the left and right sides should be the same to prevent the chain from deviating and ensure smooth operation.


The principle of the utility model is as follows:


The matching lead screw of the nut fixed on the fixed frame is rotated by a special wrench to drive the movable frame and the chain wheel to move left and right on the track. The chain also expands and contracts with the left and right movement of the chain wheel to achieve the purpose of adjusting the tightness.


The utility model has the advantages of reasonable structure, flexible and convenient use. Using the utility model, the tightness of the chain can be adjusted quickly and efficiently, and the phenomenon that the chain is too loose when the temperature rises and the chain is too tight and the chain is too tight to break during the temperature reduction process is avoided, and the normal operation of the PVC glove production line is ensured.
