Abstract
The utility model discloses a thermoplastic polyurethane (TPU) film blowing machine which comprises an extruder and a thin film rack, wherein an extrusion handpiece is arranged at one end of the extruder and connected with the thin film rack; a film blowing device is arranged on the thin film rack and comprises a film material channel, a main air ring arranged on the extrusion handpiece and a plurality of auxiliary air rings arranged on the thin film rack; a traction device is arranged above the thin film rack; and a finished product winding device is arranged on the side of the thin film rack and matched with the traction device. According to the TPU film blowing machine, a plurality of auxiliary air rings are arranged on the thin film rack; when dragged, a thin film is subjected to blow molding of compressed air, so deformation or ruckling of the thin film, which is caused by a gravity reason, can be effectively avoided; the thin film is flat and the quality of the thin film is improved.
Description
Technical field
The utility model relates to the film production equipment technical field, is specifically related to a kind of TPU inflation film manufacturing machine.
Background technology
TPU is a thermoplastic polyester, is a kind of environment-friendly type macromolecule polymer, and this material has overcome many deficiencies of PVC and PU material, has most of characteristic of rubber and common plastics, is a kind of good thin-film material.The TPU film that utilizes the TPU coating materials to prepare has good physical property avirulence, and range of application is very extensive.
At present, produce the TPU film and mainly adopt the TPU inflation film manufacturing machine, this inflation film manufacturing machine comprises that extruder and film frame are with TPU peplomer heating and melting, extrudes and steeps with utilizing compressed air to blow out film through extruder, makes film.The mode of the TPU film of the TPU inflation film manufacturing machine blowing of this mode mainly adopts upper blowing method, flat mode of blowing method and lower blowing method, and wherein upper blowing method is the mode that the most often adopts in producing.The thickness range broad of the TPU film that upper blowing method makes, thickness is relatively even, and this occupation area of equipment is less simultaneously, therefore, maximum technology of using when upper blowing method is inflation film.The equipment of this upper blowing method system TPU film generally can be provided with vane in the head position of extruder, utilizes the compressed air blown film that blows out in the vane.This upper blowing method equipment only is provided with vane in the head position, and the film that makes is again through the traction rolling, and in this process, owing to the blowing scope away from vane, film is prepattern still again, and distortion under the effect of gravity easily is wrinkling, influences the quality of film.
Summary of the invention
The purpose of the utility model is: to the deficiency of prior art, the utility model provides a kind of film quality of production good, on-deformable TPU inflation film manufacturing machine.
To achieve these goals, the utility model has adopted following technical scheme: a kind of TPU inflation film manufacturing machine comprises extruder and film frame; One end of described extruder is provided with extruder head; Described extruder head is connected setting with the film frame, is provided with the blown film device on the described film frame, and described blown film device comprises the coating materials passage, is arranged at the main air ring on the extruder head; With some auxiliary vanes that are arranged on the film frame; Described film frame top is provided with draw-gear, and film frame side is provided with finished rolling device, and described finished rolling device matches with draw-gear.
As preferably, described film frame is provided with clamping plate.After adopting above-mentioned preferred version, the inflation film manufacturing machine of the utility model can play good clamping action to film when inflation film, further avoid film in trailed process, to be out of shape, and has improved the quality of film.
As preferably, described draw-gear comprises two carry-over pinch rolls, and described carry-over pinch rolls are mutually circumscribed.After adopting above-mentioned preferred version, film passes through between two carry-over pinch rolls, when again film being played draw, can flatten film, improves the service property (quality) of film.
As preferably, described finished rolling device comprises finished product rolling support and is arranged at the finished product wind-up roll on the finished product rolling support.After adopting above-mentioned preferred version, the utility model can carry out rolling to finished films better.
As preferably, be provided with some transfer rollers between described finished rolling device and draw-gear.After adopting above-mentioned preferred version, can transmit film more reposefully, guarantee the quality of film.
The TPU inflation film manufacturing machine of the utility model has been set up some auxiliary vanes on the film frame, when film is pulled, continue to be compressed the blowing of air, effectively avoids film because of gravity distortion or crumple, guarantees the smooth of film, has improved the quality of film.
