A positioning groove that is adapted to the positioning block is provided on the inner side surface of the electric engraving roller body.

[0004] However, based on the working principle proposed in the above patent, the applicant believes that although the above device has a certain degree of heat dissipation effect, the way the fan used in the above device guides the hot air flow is likely to affect the service life of the fan and the heat dissipation effect is relatively poor. The cooling rate of the copper tube is low, which is easy to affect the production efficiency when used.

[0005] Therefore, a kind of electric engraving plate for producing plastic bags is proposed in view of the above problems. Utility Model Content

[0006] The technical problem to be solved by the utility model is that the existing technology has the disadvantage of poor heat dissipation effect, so we propose an electric engraving plate for plastic bag production.

[0007] The technical solution adopted by the utility model to solve its technical problems is: an electric engraving plate for plastic bag production, comprising an inner tube; a water outlet pipe is arranged on the surface of the inner tube, a pump is fixedly installed on one side of the inner tube, a water inlet flange is fixedly installed on the outer side of the pump, a water outlet flange is fixedly installed on the other side of the inner tube, an outer copper tube is fixedly installed on the outer side of the inner tube, and a transmission line is arranged between the inner tube and the outer copper tube.

[0008] Preferably, fixing rods are fixedly installed on both sides of the outer copper tube, and connecting plates are fixedly installed on the outer sides of the fixing rods, and the surface of the connecting plates is provided with through holes.

[0009] Preferably, a groove plate is fixedly mounted on the inner surface of the outer copper tube, and a water groove is formed between the groove plate and the inner surface of the outer copper tube.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model provides a circulation site for refrigeration circulating water by setting an inner pipe, and guides refrigeration circulating water into the water trough formed by the outer copper pipe and the trough plate by setting an outlet pipe. When the water with a relatively low temperature flows through the water trough, the high temperature on the surface of the outer copper pipe is absorbed, so that the temperature of the surface of the outer copper pipe is rapidly reduced. Since water cooling can directly contact the surface of the high-temperature object, the refrigeration efficiency is higher than that of air cooling. The water inlet flange is set to guide refrigeration circulating water into the inner pipe. The pump is set to appropriately pressurize the refrigeration circulating water so that it can form a flow effect in the water trough. The outlet flange is set to guide the heated circulating water to flow out of the inner pipe. The transmission line is set to energize the electric heating coil.

[0015] 2.
