Anti-rolling mechanism for strong cross film stretching equipment
The utility model belongs to the technical field of film stretching equipment, and particularly relates to an anti-rolling mechanism for strong cross film stretching equipment, which comprises a rack, a stretching mechanism and an anti-rolling mechanism are arranged on the rack, and the stretching mechanism comprises a first heating cylinder, a first upper traction mechanism and a first lower traction mechanism. The traction speed of the first upper traction mechanism is smaller than that of the first lower traction mechanism, the anti-rolling mechanism comprises a second heating cylinder, a second upper traction mechanism and a second lower traction mechanism are arranged above and below the second heating cylinder respectively, and the traction speed of the second upper traction mechanism is the same as that of the second lower traction mechanism. According to the utility model, the powerful crossed film is heated in the first heating cylinder, then the powerful crossed film is stretched through the speed difference between the first upper traction mechanism and the first lower traction mechanism, the powerful crossed film is secondarily heated in the second heating cylinder, and the speed of the second upper traction mechanism is the same as that of the second lower traction mechanism; and the strong cross film is prevented from curling after being stretched.

Ultrafiltration membrane stretching device
ActiveCN222605967UImprove finished product qualityUltrafiltrationMembrane stretchFiltration membrane
The utility model discloses an ultrafiltration membrane stretching device which comprises a stable base, a heating box is fixedly arranged at the left end of the top face of the stable base, a refrigerating box symmetrical to the heating box is arranged on the top face of the stable base, the top end of the heating box and the top end of the refrigerating box are jointly connected with a workbench, and a stretching frame is fixedly arranged on the top face of the workbench. A set of moving plates are arranged in the stretching frame in a bilateral symmetry and sliding mode, an air cavity communicating with the heating box and the refrigerating box is formed in the workbench, and an air expansion net plate communicating with the air cavity is arranged in the stretching frame. Compared with the prior art, the ultra-filtration membrane stretching device has the advantages that by arranging the heating box and the refrigerating box, hot air can be generated in the stretching process and is uniformly diffused into the stretching frame through the air diffusion screen plate at the top end of the air cavity, the required temperature is provided for stretching work of an ultra-filtration membrane, and after stretching is completed, the heating box stops working, so that the working efficiency is improved. The refrigeration box rapidly refrigerates to cool and mold the ultrafiltration membrane, so that the quality of finished products is improved.
