Description

Technical Field

[0001] The invention relates to the technical field of tourniquet production, in particular to a cooling molding device and method for producing a tourniquet. Background Art

[0002] The tourniquet is made of natural rubber or special rubber, a medical polymer material, and is long, flat, and highly elastic. It is suitable for one-time use in medical institutions for infusion, blood drawing, blood transfusion, and hemostasis during routine treatment and rescue; or for emergency hemostasis in limb bleeding, snake and insect bites in the wild. In the production process of the tourniquet, the product extruded by the hot melt equipment needs to be cooled to accelerate the molding of the product.

[0003] For example, the prior art CN112976530B proposes a rubber belt extrusion cooling device, which includes a water pool, a rotating disk and a water pipe located above the water pool. The water pipe is arranged horizontally, a water pump is provided between the water pipe and the water pool, a plurality of nozzles are provided on the bottom of the water pipe, and the rotating disk is located above the water pool. The device utilizes a winding device to first wind up the rubber belt, and then utilizes the centrifugal force of rotation to throw away the water to achieve water removal treatment of the rubber belt.

[0004] However, the above-mentioned prior art still has certain defects in practical application. Although the above-mentioned device can remove water from the rubber belt by utilizing centrifugal force, the above-mentioned device needs to wind the rubber belt on a turntable when in use. During winding, the rubber belts will overlap with each other, and the water at the overlapping position is difficult to be thrown out, which will result in the problem that the outer layer of the wound rubber belt is dry while the rubber belt wound on the inner layer is still wet. Moreover, after a roll of rubber belt is processed, it is necessary to stop the device and take out the rubber belt roll before continuing the processing, which is very troublesome. In view of the above problems, we provide a cooling molding device and method for producing a tourniquet to solve the above-mentioned problems. Summary of the invention
