Abstract

The invention discloses a continuous horizontal tension control device which comprises two sets of roller sets which are arranged on the left side and the right side of a film respectively. The two roller sets comprise two sets of upper pressing wheels and lower pressing wheels which are located on the upper side and the lower side of the film respectively and can clamp the film, the upper pressing wheels and the lower pressing wheels are connected with motors which drive the upper pressing wheels and the lower pressing wheels to rotate to apply force to the film and drive the film to be unfolded towards two outer sides, and the motors are connected with controllers which control the output torque of the motors. The continuous horizontal tension control device applies horizontal action force (namely friction force) to the film, and meanwhile the motors output stable torque through the controllers, so that the film bears constant tension force in the uncoiling or coiling process when moving longitudinally, the phenomenon that the damage, shrink and tensile deformation of the film surface due to tension change can not occur, production technology stability of products is increased, and product quality is improved.

Description

A kind of continuous transverse tenslator

Technical field

The present invention relates to a kind of tenslator, especially relate to film series products in rolling and unreel the control setup of the horizontal tension in process.

Background technology

Conventionally need to be to film rolling in masking or the film course of processing and tension force while unreeling control, to guarantee that face can not produce breakage, wrinkling and tensile deformation etc. because of tension variation, also to guarantee that the phenomenons such as the lax or volume heart of film is wrinkling can not occur finished product (rolling) simultaneously.

Traditional tension control system has the controller+receipts (putting) of tension control assembly+magnetic-powder clutch+receipts (putting) volume actuating unit, frequency converter+receipts (putting) volume actuating unit, tape pulse output to roll up three kinds of actuating units, these systems can only be used for controlling longitudinal tension force, can not be used for the control of horizontal tension.Conventional horizontal tension control process generally adopts chain-type or pin type extension fixture, and equipment complexity, can only carry out lateral magnification in addition, can not control the size of horizontal tension.

Summary of the invention

In order to address the above problem, the object of the present invention is to provide a kind of simple in structure, again can continuous control film series products in rolling with unreel the control setup of the horizontal tension in process.

The present invention is that the technical scheme that its technical matters of solution adopts is:

A kind of continuous transverse tenslator, comprise two groups of roller set that are separately positioned on the film left and right sides, two groups of roller set comprise two groups of upper contact roller and lower contact rollers that lay respectively at film upper and lower sides and can clamp this film, described upper contact roller and lower contact roller are connected with the motor that drives their rotations and force on film and drive film to open toward its two lateral direction, and described motor is connected with the controller of controlling its output torque.

As the improvement of technique scheme, in the wheel outer rim of described upper contact roller and lower contact roller, be evenly distributed with multiple bearings that can freely rotate around its rotating shaft, the rotating shaft of described bearing is respectively perpendicular to the rotating shaft of upper contact roller and lower contact roller.

As the further improvement of technique scheme, the appearance of described bearing is also enclosed with one deck rubber.

In order to make it possible to regulate the gap between upper contact roller and lower contact roller, avoid contact roller and lower contact roller too small or excessive to the thrust of film, described upper contact roller and/or lower contact roller are connected with and drive its actuating device moving up and down.

Further, described actuating device is cylinder or hydraulic actuating cylinder.

The invention has the beneficial effects as follows: because horizontal tension control setup of the present invention applies horizontal force (being friction force) by two groups of roller set to film, simultaneously by the torque of controller control motor stable output, make film can be subject to constant tension force in the uncoiling vertically moving or wrapup procedure, guarantee that face can not produce because of tension variation the phenomenons such as breakage, wrinkling and tensile deformation, both increase the stable processing technique of product, improved again the quality of product.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.

Fig. 1 is structural representation of the present invention;

Fig. 2 is the structural representation of one group of roller set in the present invention.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of continuous transverse tenslator, comprise two groups of roller set 1 that are separately positioned on film 5 left and right sides, two groups of roller set 1 comprise two groups of upper contact roller 11 and lower contact rollers 12 that lay respectively at film 5 upper and lower sides and can clamp this film 5, described upper contact roller 11 and lower contact roller 12 are connected with the motor 2 that drives their rotations and force on film 5 and drive film 5 to open toward its two lateral direction, described motor 2 is connected with the controller 4 of controlling its output torque, horizontal tension control setup of the present invention applies horizontal force (being friction force) by two groups of roller set to film, simultaneously by the torque of controller control motor stable output, make film can be subject to constant tension force in the uncoiling vertically moving or wrapup procedure, guarantee that face can not produce breakage because of tension variation, the phenomenons such as wrinkling and tensile deformation, both increased the stable processing technique of product, improve again the quality of product, the present invention can apply continuous horizontal force to it by two groups of roller set 1 in the uncoiling of film 5 or wrapup procedure in addition, realize the continuous transverse tension force control to film 5.

Further, in order to reduce uncoiling that upper contact roller 11 and lower contact roller 12 vertically move film 5 or the impact of rolling work, in the wheel outer rim of described upper contact roller 11 and lower contact roller 12, be evenly distributed with multiple bearings 3 that can freely rotate around its rotating shaft, the rotating shaft of described bearing 3 is respectively perpendicular to the rotating shaft of upper contact roller 11 and lower contact roller 12, in the time that two groups of roller set 1 are worked, rotate and the horizontal tension force of generation that rubs on the surface of film 5 by upper contact roller 11 and lower contact roller 12, make film 5 be subject to the constant-tension of two groups of roller set 1 to it and keep open configuration and can not produce breakage, the phenomenons such as wrinkling and tensile deformation, simultaneously because bearing 3 can freely rotate around its rotating shaft, therefore film 5 is in the process of the uncoiling vertically moving or rolling, also can be with dynamic bearing 3 rotations, make contact roller 11 and lower contact roller 12 in the time rotating, can not have influence on vertically moving of film 5, in order to prevent that bearing 3 from damaging film 5, preferably, the appearance of described bearing 3 is also enclosed with one deck rubber.

Further again, in order to regulate the gap between upper contact roller 11 and lower contact roller 12, contact roller 11 and the gripping power of lower contact roller 12 to film 5 in control, described upper contact roller 11 and/or lower contact roller 12 are connected with and drive its actuating device moving up and down, in the present invention, described actuating device is cylinder or hydraulic actuating cylinder, certainly adopts driven by motor screw body mode to realize moving up and down of contact roller 11 and/or lower contact roller 12 also passable.

The foregoing is only preferential embodiment of the present invention, as long as within the technical scheme that realizes the object of the invention with basic identical means all belongs to protection scope of the present invention.
