Manufacturing method of coating liquid condensation system for coating tank of latex glove automatic production line

- Sep 26, 2020-

Background technique:


In the production process of latex gloves, it is necessary to evenly impregnate a coating solution on the surface of the glove before crimping and drying. The coating solution can form an isolation layer on the surface of the glove. After the glove is demolded and turned over, it will be produced on the inner wearing surface of the glove. The isolation effect can prevent adhesion and is easy to wear. However, the coating liquid is a high molecular water-based polymer dispersion. When the temperature rises, it will cause bacteria in the coating liquid to decompose the polymer. At the same time, the latex The penetration of protein into the coating liquid will also accelerate the growth of bacteria, which will eventually lead to deterioration, corruption, and odor of the coating, and then lose its efficacy. In actual use, it is inevitably affected by the mold temperature and it is difficult to control it. temperature.

Technical realization elements:


The purpose of the utility model is to provide a coating liquid condensing system for the coating tank of the latex glove automatic production line which can effectively prolong the use period of the coating liquid.


The technical solution of the utility model is:


A coating tank coating liquid condensation system of a latex glove automatic production line, including a coating tank, characterized in that: the outer surface of the coating tank is covered with a thermal insulation cotton layer, and the outer surface of the thermal insulation cotton layer is wrapped with an aluminum plate; Eight stainless steel coils are evenly laid on the bottom of the tank and on the surface of the aluminum plate. Both sides of the stainless steel coils are connected by stainless steel pipes as crosspieces. One side of the crosspiece is opened with a ø400mm hole on each side as the cooling water inlet. Install a stainless steel ball valve on the side of the water inlet and the water outlet, and a stainless steel check valve on the side of the water outlet. The inlet and outlet are connected with the external refrigeration unit for the closed loop of the condensing system;


The above-mentioned eight stainless steel coil pipes are divided into four groups with two adjacent ones as a group. The two adjacent groups are connected by crosspieces on both sides, and the group pipe and the group pipe form a one-way flow to ensure cooling Water always enters from the water inlet and flows out from the outlet on the other side;


The safety distance between the stainless steel coil and the fingertips of the mold running on the production line is more than 40mm, and the rails on both sides are lower than the coating liquid level, so that the entire condensing device is completely immersed below the coating liquid, and only The outlet pipe is connected with external equipment.


The heat exchange area of the eight stainless steel coils is 2.5 square meters, which is equivalent to the surface heat exchange area of the inner wall of the coating tank.


The utility model can effectively suppress the increase in the temperature of the coating liquid caused by the continuous immersion of the mold, and adopts methods such as built-in condenser, cooling water circulation, and heat preservation outside the tank to meet the temperature requirements of the coating liquid, and extend the service life of the coating liquid as much as possible , To achieve the desired purpose.
