Abstract

The utility model relates to a film edge breakage preventing mechanism which comprises air blowing pipes symmetrically arranged at the left end and the right end of a guide roller at the outlet of a plastic extruding machine, wherein the air outlet directions of the air blowing pipes face to the same side edge of a plastic film wound on the guide roller, the air blowing pipes are all arranged on installation blocks, and the installation blocks are all connected with a rack through swing rods. Simple structure, the plastic film homonymy border of establishing is all gone up around to the deflector roll to the direction of giving vent to anger of gas blow pipe, can be to the plastic film border of homonymy toward inboard high pressure gas of blowing, makes high temperature, soft thin plastic film border toward inboard deformation bodiness under high pressure draught's disturbance, and subsequent transmission in-process is difficult for tearing the tear.

Description

Film edge breaking prevention mechanism

Technical Field

The utility model relates to a film edge breakage preventing mechanism.

Background

After passing through the outlet of the plastic extruding machine, the plastic film is wound and conducted on the upper part of the guide roller, so that the plastic film is conveniently transmitted to the guide roller of other working procedures. The plastic film passing through the outlet of the plastic extruding machine has higher temperature and thin and soft texture, and the left and right edges of the plastic film are easy to tear and tear in the conveying process.

SUMMERY OF THE UTILITY MODEL

In view of the defects of the prior art, the utility model aims to provide a film edge breakage preventing mechanism which is simple in structure, convenient and efficient.

In order to solve the technical problems, the technical scheme of the utility model is as follows: the utility model provides a prevent membrane broken edge mechanism, includes the gas blow pipe at both ends about the deflector roll of symmetry position extruding machine export, and the plastic film homonymy border of establishing is all around on the deflector roll to the direction of giving vent to anger of gas blow pipe, and the gas blow pipe is all installed on the installation piece, and the installation piece is all connected with the frame through the pendulum rod.

Preferably, the top end of the swing rod is fixedly connected with the rack through a bolt, through holes for the swing rods on the same side to penetrate through from top to bottom are formed in the mounting block, and first fastening screws for jacking the swing rods in the through holes are screwed on the mounting block.

Preferably, all be equipped with on the installation piece and be used for the homonymy gas blow pipe along the through-hole that the deflector roll axial was worn to establish, all the spiro union has the second holding screw that is used for the inside gas blow pipe of tight through-hole in top on the installation piece.

Preferably, the inner ends of the air blowing pipes extend obliquely from top to bottom towards the inner side and are not in contact with the edges of the plastic films wound on the guide rollers, and the outer ends of the air blowing pipes are connected with an air source through hoses.

Preferably, the material of the air blowing pipe is stainless steel.

Compared with the prior art, the utility model has the following beneficial effects: simple structure, the plastic film homonymy border of establishing is all gone up around to the deflector roll to the direction of giving vent to anger of gas blow pipe, can be to the plastic film border of homonymy toward inboard high pressure gas of blowing, makes high temperature, soft thin plastic film border toward inboard deformation bodiness under high pressure draught's disturbance, and subsequent transmission in-process is difficult for tearing the tear.

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

FIG. 1 is a schematic configuration diagram of an embodiment of the present invention.

Fig. 2 is a partially enlarged view a of fig. 1.

Detailed Description

The utility model is further explained below with reference to the drawings and the embodiments.

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

As shown in fig. 1-2, the embodiment provides a film edge breakage preventing mechanism, which includes blowing pipes 3 symmetrically located at the left and right ends of a guide roller 2 at the outlet of an extruding machine 1, wherein the air outlet directions of the blowing pipes are all towards the same side edge of a plastic film wound on the guide roller, the blowing pipes are all installed on an installation block 4, and the installation block is connected with a rack through a swing rod 5.

In the embodiment of the utility model, the top ends of the swing rods are fixedly connected with a machine frame 7 through bolts 6, through holes for the swing rods to penetrate from top to bottom on the same side are formed in the mounting blocks, and first set screws 8 for jacking the swing rods in the through holes are screwed on the mounting blocks.

In the embodiment of the utility model, through holes for the air blowing pipes on the same side to axially penetrate along the guide roller are arranged on the mounting blocks, and second set screws 9 for jacking the air blowing pipes in the through holes are screwed on the mounting blocks.

In the embodiment of the utility model, the inner ends of the air blowing pipes extend obliquely from top to bottom towards the inner side and are not in contact with the edge of the plastic film wound on the guide roller, and the outer ends of the air blowing pipes are connected with an air source through hoses.

In the embodiment of the utility model, the material of the air blowing pipe is stainless steel.

The working principle of the film edge breakage preventing mechanism is as follows: simple structure, the plastic film 10 homonymy border of establishing is all gone up around to the deflector roll to the direction of giving vent to anger of gas blow pipe, can be to the plastic film border of homonymy toward inboard high pressure gas of blowing, makes high temperature, soft thin plastic film border toward inboard deformation bodiness under high pressure draught's disturbance, and subsequent transmission in-process is difficult for tearing the tear.

When the device is used, the bolt at the top end of the swing rod can be loosened and tightened, and the angle of the swing rod can be adjusted. The set screw can be tightened and loosened to adjust the height and the axial position of the air blowing pipe. So as to adapt to plastic films with different specifications.

The foregoing is directed to preferred embodiments of the present invention, other and further embodiments of the utility model may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention are within the protection scope of the technical solution of the present invention.
