Problems solved by technology
[0003] A Chinese patent discloses a cooling drum (authorized notification number CN208118252U). This patent technology makes the water inlet speed higher than the water outlet speed by making the water inlet flow opening area larger than the water outlet flow opening area to ensure that the water interlayer is at full capacity. state, thereby improving its cooling effect, but the seal between the roller and the roller shaft is not good, and it is prone to leakage during long-term use, which will cause production accidents

The invention relates to the technical field of plastic film production, and discloses a cooling drum structure for plastic film production, including a drum assembly, the front and rear ends of the drum assembly are fixedly connected with rotary joints, and the front and rear ends of the outer side of the drum assembly are close to the Bearing housings are installed on one side of the rotary joint, and the side of the outer side of the drum assembly close to the rear rotary joint is fixedly connected with a motor through a pulley set. In the present invention, the protruding piece of the rotating disk is embedded in the sealing piece of the cooling drum, and an "O" ring is placed between the protruding piece and the sealing piece for sealing, so that the drum assembly forms a whole, thereby ensuring the safety of the drum assembly. Cooling water leakage occurs during high-speed rotation. When the drum assembly rotates at high speed, the rotor of the rotating assembly rotates with the joint water pipe of the rotating disc, while the inner pipe assembly of the rotating joint remains stable, which further ensures the cooling water. The tightness of the cooling drum improves the safety when the cooling drum is working.
Description
technical field [0001] The invention relates to the technical field of plastic film production, in particular to a cooling drum structure for plastic film production. Background technique [0002] The temperature of the surface of the drum will continue to rise during the production process of high-temperature melting plastic raw materials. If the temperature cannot be dissipated quickly, the quality of the plastic film will be seriously affected. Therefore, it is necessary to provide circulating cooling water in the drum to bring Take the heat of the film, so that the film can quickly drop to the appropriate temperature, so as to achieve the purpose of setting. [0003] A Chinese patent discloses a cooling drum (authorized notification number CN208118252U). This patent technology makes the water inlet speed higher than the water outlet speed by making the water inlet flow opening area larger than the water outlet flow opening area to ensure that the water interlayer is at f...
