Film pipe internal circulation water cooling device of film blowing machine

Abstract

The invention discloses a film pipe internal circulation water cooling device of a film blowing machine. Previous film pipe water cooling device is arranged outside a film pipe, the cooling speed is slow and water resource is wasted. An internal circulation water cooling device is arranged inside a film pipe and the internal circulation water cooling device composed of a cooling core model, a vacuum chamber inner container, various cooling inlet and outlet pipes which are sleeved coaxially and mutually, a multifolded bent water flow channel and a water absorption ring. Water in the water flow channel goes out and directly flows into the outer core walls of the cooling core model along the film pipe, a water film is formed and the inner wall of the film pipe is subjected to water cooling directly and effectively. The water stained on the inner wall of the film pipe is rapidly sucked dry in a vacuum suction way by the water absorption ring connected with the vacuum chamber inner container, thus the film pipe after cooling can go into the next production process rapidly. The whole device is simple in structure, has rapid cooling speed, raises the production benefits and saves energy. The water cooling device is widely suitable for film pipes or molding pipes of various film blowing machines, blow molding machines and the like.

Description

technical field [0001] The invention relates to a cooling device inside a film tube of a blown film machine, in particular to a circulating water cooling device inside the film tube of a blown film machine. Background technique [0002] The film blowing process of the film blowing machine is not in place in one step, but the required film can be achieved through multiple blown film production processes, and in the process of each blown film production process, the cooling of the film tube has a great impact on the quality and production of the product. Benefits will have a huge impact; in order to shorten the cooling time, the general blown film production process is to set an annular water spray ring outside the film tube or spray water directly to the film tube. Water-cooling the outside of the unit is a waste of water resources and the cooling effect is not very good. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present...
