Abstract

The utility model discloses a guide roller of a film blowing machine. The guide roller of the film blowing machine comprises a roller body. The outer surface of the roller body is provided with an antiskid stripe structure; the outer layer of the roller body is provided with an elastic layer; a plurality of grooves are evenly distributed on the outer surface of the elastic layer; the depth and the width of each groove are respectively bigger than 0.8mm; each groove is spiral; the interior of the roller body is of a hollow structure; the end part of the roller body is provided with a bearing; the bearing and a transmission structure are in transmission connection; the elastic layer is a spongy layer or a foam layer. The guide roller disclosed by the utility model has the advantage that the guide roller can be used for positioning guide or flattening during a transfer process of the film blowing machine. As the outer layer of the roller body is additionally provided with the flexible spongy layer, under the condition that stress between the surface of the guide roller and a plastic film is too high due to various reasons, the spongy layer on the surface of the guide roller firstly elastically deforms always, and therefore, the plastic film can be prevented from being pulled and damaged.

Description

A kind of deflector roll of inflation film manufacturing machine

Technical field

The utility model belongs to the technical field of film blowing device, is specifically related to a kind of deflector roll of inflation film manufacturing machine.

Background technology

Guide rail outside face in existing inflation film manufacturing machine is all hard, is easy to pull film.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of guide roller of film blowing machine is provided, and it can effectively avoid pulling plastic film.

The utility model is that the technical scheme that its technical matters of solution is taked is:

A kind of deflector roll of inflation film manufacturing machine, comprise roll body, the outside face of described roll body is provided with anti-skidding striated structure, at the skin of described roll body, is provided with posterior limiting, and the outside face of described elastic layer is evenly equipped with many grooves, and depth of groove and width all are greater than 0.8mm, groove is spiral fashion, roll body inner hollow structure, and the end of roll body is provided with bearing, bearing and drive mechanism are in transmission connection, and described elastic layer is spongy layer or froth bed.

The utlity model has following advantage and effect: deflector roll of the present utility model can be for orientation direction or the flattening of the transport process of inflation film manufacturing machine.Owing at the roll body skin, setting up soft spongy layer, between deflector roll appearance and plastic film, due to various former solid, in the excessive situation of stress, always elastic deformation first appears in the spongy layer of deflector roll appearance, thereby can avoid pulling plastic film.

The accompanying drawing explanation

The schematic diagram of the cross-sectional plane that Fig. 1 is the utility model deflector roll.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further illustrated.

The deflector roll of a kind of inflation film manufacturing machine as shown in Figure 1, comprise roll body 1, the outside face of described roll body 1 is provided with anti-skidding striped 2 structures, at the skin of described roll body 1, is provided with a spongy layer 3, the outside face of described spongy layer 3 is evenly equipped with many grooves 4, and groove 4 degree of depth and width all are greater than 0.8mm.Roll body inner hollow structure, lightweight, the end of roll body is provided with bearing, and bearing and drive mechanism are in transmission connection, and transmission is more flexible, and described elastic layer is spongy layer or froth bed, surface is soft.

Deflector roll of the present utility model can be for orientation direction or the flattening of the transport process of inflation film manufacturing machine.Owing at the roll body skin, setting up soft spongy layer, between deflector roll appearance and plastic film, due to various former solid, in the excessive situation of stress, always elastic deformation first appears in the spongy layer of deflector roll appearance, thereby can avoid pulling plastic film.

Claims

1. the deflector roll of an inflation film manufacturing machine, comprise roll body, it is characterized in that: the outside face of described roll body is provided with anti-skidding striated structure, at the skin of described roll body, is provided with posterior limiting, and the outside face of described elastic layer is evenly equipped with many grooves, and depth of groove and width all are greater than 0.8mm, groove is spiral fashion, roll body inner hollow structure, and the end of roll body is provided with bearing, bearing and drive mechanism are in transmission connection, and described elastic layer is spongy layer or froth bed.
