CN202826396U - Pressure feed device of plastic film two-way stretch equipment - Google Patents

Abstract

The utility model provides a pressure feed device of plastic film two-way stretch equipment. The pressure feed device comprises a base, transmission shafts, and pressure rollers, and is characterized in that the pressure rollers are formed by an upper roller and a lower roller, outer surfaces of the two pressure rollers are respectively wrapped with a rubber layer, the two pressure rollers are respectively connected on the base through the two transmission shafts, and the axial length of the upper roller is smaller than that of the lower roller. The pressure feed device enables the plastic film two-way stretch equipment to work better and well press and guide films, enables the next procedure, namely the edge cutting procedure for cutting the full-size films, to be smooth, and enables edges of the films to be in order.

Description

The force feed device of plastic sheeting biaxial tension equipment

Technical field

A kind of plastic sheeting biaxial tension of the utility model equipment, particularly a kind of plastic sheeting biaxial tension equipment are assisted the force feed device.

Background technology

In the prior art, plastic sheeting biaxial tension equipment is the equipment by the obtained plastic sheeting of biaxial tension, its operation principle is the technique through the processing of the means specially-shapeds such as physics, chemistry, machinery, be lower than the film fusing point, be higher than under the vitrification point, thick film or plastics plain film are carried out biaxial tension, carry out under tense situation then that thermal finalization is processed and the goods that obtain.In the process of this oriented film, owing to not being equipped with corresponding force feed device, can cause the edge generation of the film that is stretched irregular, be difficult to cooperate next process to carry out smoothly.This is the deficiencies in the prior art.

Summary of the invention

The purpose of this utility model is to provide a kind of and can compresses preferably and the servicing unit of the biaxial tension equipment of delivery film.

The utility model is achieved in that a kind of force feed device of plastic sheeting biaxial tension equipment, comprise support, power transmission shaft, pinch roller, pinch roller by on take turns with lower whorl and form, two pinch roller outer surfaces are coated with one deck rubber layer, two pinch rollers are connected on the support by two power transmission shafts respectively, on the axial length of taking turns less than the axial length of lower whorl.

The radially oscilaltion of described upper wheel shaft, its range is 2/3rds of rubber layer thickness.

The utility model beneficial effect is: plastic sheeting biaxial tension equipment is better worked, can compress better film and delivery film, can make the next process of this equipment, the rim charge operation that namely cuts off the view picture film becomes more smooth, makes the film not care about one's appearance more neat.The rubber layer that can also ensure better pinch roller can not produce too large damage, prolongs its service life.In addition, can also make the easy fast dismantling of upper whorl axial from, shorten maintenance time of this device.

The specific embodiment

Such as Fig. 1-shown in Figure 5, as seen the device shown in the utility model, it is a kind of force feed device of plastic sheeting biaxial tension equipment, mainly combined by support 1, power transmission shaft, pinch roller, pinch roller by on take turns 2 and form with lower whorl 3, on take turns 2 and play the press mold effect, lower whorl 3 plays leads membrane interaction, two pinch roller outer surfaces are coated with one deck rubber layer, and two pinch rollers are connected on the support 1 by two power transmission shafts respectively, on take turns 2 axial length less than the axial length of lower whorl 3.On take turns the radially oscilaltion of 2 power transmission shafts, its range is 2/3rds of rubber layer thickness.The utility model beneficial effect is: plastic sheeting biaxial tension equipment is better worked, can compress better film and delivery film, can make the next process of this equipment, the rim charge operation that namely cuts off the view picture film becomes more smooth, makes the film not care about one's appearance more neat.The rubber layer that can also ensure better pinch roller can not produce too large damage, prolongs its service life.In addition, can also make the easy fast dismantling of upper whorl axial from, shorten maintenance time of this device.
