Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag surface coating, in particular to a packaging bag coating circulating water cooling device. Background Art

[0002] The commonly used 25KG chemical packaging bags now all use paper-plastic composite bags, with kraft paper as the outer layer and woven cloth as the inner layer, and the inner and outer layers are tightly bonded together by a coating layer in the middle to achieve a certain strength; the originally brittle paper has a certain tension due to the longitudinal and transverse ribs of the inner layer, and maintains the original colorful printing performance of the paper and the anti-slip performance with a large friction coefficient between the papers; after the inner layer of woven cloth is composited and fixed, the longitudinal and transverse warp threads will not be loose, thereby improving the strength of the composite bag; and the dense coating layer in the middle plays a good sealing role, which is particularly suitable for the packaging and transportation of chemical granular materials; however, this kind of paper-plastic composite bag is not easy to recycle after use, and incineration is not only a waste of resources, but also causes great pollution to the environment.

[0003] In the prior art, the surface of the packaging bag needs to be cooled and shaped after coating, so that the film layer of the packaging bag will not be rubbed off. However, the prior art is to cool naturally, which has a slow cooling speed and low efficiency. Summary of the invention

[0004] In view of this, the purpose of the utility model is to provide a packaging bag coating circulating water cooling device which can cool the surface of the packaging bag after the packaging bag is coated.

[0005] The utility model is implemented by the following method: a packaging bag coating circulating water cooling device comprises a sprayer, a conveyor belt is provided at the material outlet of the sprayer, a gantry is provided on the conveyor belt, a cooling box is provided on the upper surface of the horizontal plate of the gantry, a water storage box is provided at the left end of the upper surface of the cooling box, an air outlet pipe is provided in the cooling box, an air inlet pipe is connected to the air outlet pipe, a plurality of air outlet branch pipes are connected to the lower surface of the air outlet pipe at equal distances, a plurality of air outlet nozzles are connected to the air outlet branch pipes, the air outlet nozzles are arranged on the lower surface of the cooling box, a cooling element is provided in the cooling box, and the cooling element is connected to the water storage box.

[0006] Furthermore, a first meandering cooling pipe is arranged in the water storage tank body, the cooling element includes a second meandering cooling pipe, the second meandering cooling pipe is arranged in the cooling tank body, the water inlet of the second meandering cooling pipe is connected to the water storage tank body, the water outlet of the second meandering cooling pipe is connected to a water pump, the water pump is arranged in the lower left corner of the water storage tank body, and the second meandering cooling pipe is arranged around between the air outlet pipe and the air outlet branch pipe.

[0007] The beneficial effects of the utility model are as follows: the utility model adds a cooling box, a water storage box and an air outlet nozzle to the device, which can evenly spray cold air onto the surface of the packaging bag after coating, thereby facilitating the cooling of the surface of the packaging bag and better facilitating the cooling and fixing of the film layer on the surface of the packaging bag; the utility model has a simple structure and is easy to operate, and can effectively save manpower and material resources and improve work efficiency.
