Abstract

The utility model discloses a rolling mechanism for a film blowing unit. The rolling mechanism comprises a rolling bracket, two groups of rolling shafts which are arranged on the rolling bracket in a rotatable mode and two rolling motors, and is characterized in that: the two groups of rolling shafts are symmetrically arranged right and left; two rolling shafts are arranged in each group up and down; the two rolling motors are arranged right and left; and one rolling motor on the left side drives one group of rolling shafts on the left side, and the other rolling motor on the right side drives the other group of rolling shafts on the right side. The rolling mechanism has the advantages that: the rolling requirement of the film blowing unit is well met, and the rolling efficiency of the film blowing unit is improved.

Description

The rolling-up mechanism of blown film unit

[technical field]

The utility model relates to a kind of blown film unit that plastic sheeting is produced that is used for, and is specifically related to a kind of rolling-up mechanism of blown film unit.

[background technology]

The blown film unit is used for the production of plastic sheeting, and present blown film unit, its rolling-up mechanism comprise rolling support, a Scroll and a winding motor, and function ratio is more single.Because have only a Scroll, the film that the blown film unit blows out can only carry out rolling by bilayer, can not satisfy the needs of rolling single thin film.In addition, after the film of Scroll rolling reached given size, needs unloaded the film of rolling earlier from Scroll, and then change new core film tube, and for this reason, the middle time gap that pauses is longer, and rolling efficient is lower.

[summary of the invention]

In view of the deficiency that background technology exists, the technical matters that the utility model will solve is to be to provide a kind of can better satisfy the rolling needs, improves the blown film unit rolling-up mechanism of rolling efficient.

The utility model is implemented through following technical scheme:

The rolling-up mechanism of blown film unit; Comprise rolling support, Scroll and winding motor, Scroll is located on the rolling support rotationally, it is characterized in that: said Scroll left-right symmetric is provided with two groups; Have two on every group; Be provided with two about said winding motor, a winding motor on the left side drives one group of Scroll on the left side, and a winding motor on the right drives one group of Scroll on the right.

After adopting technique scheme; If the bilayer film that the blown film unit blows out is split up into two single thin films with cutting knife; So two single layer films can through about last Scroll carry out rolling respectively, so the utility model has satisfied the needs of rolling single thin film; In addition; After the film of last Scroll rolling reaches given size; Can the film quick traction be carried out rolling to following Scroll, after Scroll began rolling work down, the rolling film that will go up Scroll again unloads changed new core film tube; Because the rolling of film does not almost pause, so improved rolling efficient.

[description of drawings]

Accompanying drawing 1 is the structural representation of the utility model

[specific embodiment]

Shown in accompanying drawing 1, the rolling-up mechanism of blown film unit comprises rolling support 8, Scroll 6 and winding motor 2; Scroll 6 is located on the rolling support 8 rotationally, and said Scroll 6 left-right symmetric are provided with two groups, has two on every group; The axle head of every Scroll 6 is connected with rolling gear 7, rolling gear 7 and transmission gear 5 engagements, and the outside axle head that the transmission shaft 4 of transmission gear 5 is installed is equipped with driving chain wheel 3; About said winding motor 2 is provided with two, the axle head of winding motor 2 is connected with motor sprocket 1, two driving chain wheels on the motor sprocket transmission left side of left side winding motor axle head; Two driving chain wheels on motor sprocket transmission the right of the right winding motor axle head; Like this, the winding motor on the left side drives one group of Scroll on the left side, and the winding motor on the right drives one group of Scroll on the right.

The utility model is performed such work; Under the traction of nip rolls 9; Bilayer film is carried from the bottom up, and being separated at cutting knife 10 places is two single thin films, under the driving of left and right sides winding motor; About two go up Scrolls two single thin films carried out rolling respectively, satisfied the needs of rolling single thin film; After the film of last Scroll rolling reaches given size; The film quick traction is carried out rolling to following Scroll; After Scroll begins rolling work down; The rolling film that to go up Scroll again unloads changes new core film tube, because almost not pause of the rolling of film, so improved rolling efficient.

Claims
