A kind of packaging material tension force and conveying anti-deflection device
Technical field
The utility model belongs to package packing machine field, more particularly, to a kind of packaging material tension force and conveying anti-deflection device.
Background technology
Its structure of the tenslator of existing packaging facilities is essentially the patent such as Publication No. CN203064241U
Technology, the tenslator of the case includes the first support shaft 2, the second support shaft 3, the 3rd support shaft 5, and packaging film 1 leads to successively
The first support shaft, the second support shaft, the 3rd support shaft are crossed, GRAVITY CONTROL device is provided between the second support shaft and the 3rd support shaft
4, the GRAVITY CONTROL device is less than the second support shaft and the level height of the 3rd support shaft.
This prior art, the concentric and scale error produced due to roller in processing, assembling is so that packaging material conveying
During produce deviation phenomenon, cause packaging material flash, cut unequal defect.
The content of the invention
The purpose of this utility model is to provide one kind and is difficult few sideslip, flash, the uniform packaging material tension force of cutting and conveys anti-
Deflection device, is especially suitable for packaging facilities.
The technical solution of the utility model is:A kind of packaging material tension force and conveying anti-deflection device, including the first deflector roll, second lead
Roller, the 3rd deflector roll and weight edger roll, the lower section between first deflector roll and the second deflector roll are provided with gravity-roller, second deflector roll
Side is provided with the 3rd deflector roll, and first deflector roll, the second deflector roll, the concentric place of the 3rd deflector roll and gravity-roller are equipped with central shaft,
First deflector roll, the second deflector roll, the central shaft of the 3rd deflector roll and gravity-roller are mounted in frame, first deflector roll,
Two deflector rolls, the two ends of the 3rd deflector roll are equipped with adjustable back-up ring;
Further, the two ends of the central shaft of the gravity-roller are provided with gravitational equilibrium regulation ring at gravity-roller, described
The axle surface at the two ends of the central shaft of gravity-roller is provided with graduated scale.
The utility model has the advantages and positive effects of:Due to using above-mentioned technical proposal, packaging material is difficult sideslip, hair
Side is few, cutting is uniform.

Fig. 3 is lateral section structural representation of the present utility model.
In figure:
First deflector roll 1, the second deflector roll 2, the 3rd deflector roll 3, weight edger roll 4, central shaft 5, adjustable back-up ring 6, gravitational equilibrium are adjusted
Save ring 7, graduated scale 8.
Embodiment
The utility model is elaborated below in conjunction with the accompanying drawings.
As Figure 1-3, a kind of packaging material tension force of the utility model and conveying anti-deflection device, including the first deflector roll 1, second lead
Lower section between roller 2, the 3rd deflector roll 3 and weight edger roll 4, the deflector roll 2 of the first deflector roll 1 and second is provided with gravity-roller 4, described second
The side of deflector roll 2 is provided with the 3rd deflector roll 3, first deflector roll 1, the second deflector roll 2, the 3rd deflector roll 3 and gravity-roller 4 concentric place it is equal
Provided with central shaft 5, first deflector roll 1, the second deflector roll 2, the central shaft 5 of the 3rd deflector roll 3 and gravity-roller 4 are mounted in frame
(not shown), first deflector roll 1, the second deflector roll 2, the two ends of the 3rd deflector roll 3 are equipped with adjustable back-up ring 6;
Further, the two ends of the central shaft 5 of the gravity-roller 4 are provided with gravitational equilibrium regulation ring 7 at gravity-roller 4,
The axle surface at the two ends of the central shaft 5 of the gravity-roller 4 is provided with graduated scale 8.
The course of work of this example:The graduated scale 8 at the two ends of the gravity regulation ring with weight edger roll 4 and the central shaft 5 of gravity-roller 4
Avoid because the weight that cause such as processing, assembling and scale error are so that produce deviation phenomenon, simultaneously in packaging material course of conveying
First deflector roll 1, the second deflector roll 2, the 3rd deflector roll 3 be with adjustable back-up ring, it is to avoid packaging material flash, cuts unequal defect.
One embodiment of the present utility model is described in detail above, but the content is only of the present utility model
Preferred embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.It is all to be made according to present utility model application scope
Equivalent change with improve etc., all should still belong within patent covering scope of the present utility model.
