Blown film machine tube film water removal device

Abstract

The invention discloses a tube film dewatering device of a film blowing machine. The tube film dewatering device comprises a supporting frame, the supporting frame comprises a lower supporting plate,a supporting column and an upper supporting plate, the lower supporting plate and the upper supporting plate are fastened and connected through the supporting column, and first telescopic cylinders symmetrically distributed are arranged at the upper end of the lower supporting plate and the lower end of the upper supporting plate; and the top ends of the telescopic rods of the two first telescopiccylinders located at the upper end of the lower supporting plate and the lower end of the upper supporting plate are fastened and connected with a first supporting block and a second supporting block, a first limiting ring is arranged at the upper end of the first supporting block, and a clamping unit is arranged at the upper end of the second supporting block. A tube film device needing to suckthe surface water is placed between sponge in a clamping block and sponge clamped in the first limiting ring, the first telescopic cylinder is adjusted, the sponge is attached to the tube film surface, and water sucking is conducted on the tube film.

Description

technical field [0001] The invention relates to a tube film processing device of a film blowing machine, in particular to a water removal device for the tube film of a film blowing machine. Background technique [0002] In the production process of the tube film of the blown film machine, after cooling with water, removing the water on the surface of the tube film is one of the important steps. At present, the method of wrapping the rag around the tube film is usually used. Although this method wraps the rag tightly On both sides of the tube film, but the water removal effect is not ideal, and too tight winding will form a ribbon-like pattern in the tube film, which seriously affects the transparency of the tube film, and the product qualification rate is low. [0003] The prior art has a dewatering device for the tube film of the blown film machine. For example, the Chinese patent document discloses a dewatering device for the tube film of the blown film machine [applicatio...

Problems solved by technology

[0005] 2. In the process of dewatering the surface of the tube membrane, when the sponge absorbs a certain amount of water, if it continues to absorb the water quality of the tube membrane surface, it is easy to leave water quality traces on the surface of the tube membrane. At this time, the sponge needs to be dehydrated, and the utility model, There is no introduction to dewatering the sponge from time to time in the process of removing water from the tube membrane, but in industrial production, the tube membrane is produced in an assembly line, so the utility model has certain limitations on the water removal of the tube membrane
