Further, the motor is located at the bottom of the base.

Furthermore, the number of the rollers is five, and the rollers are distributed around the rotating ring in a central symmetry manner.

Further, the inside of tensioning roller has seted up the cavity, circumference equidistance distributes in the cavity has a plurality of spring.

Further, the specific shape of the support is a C-shaped structure.

Further, the motor is specifically a direct current speed reduction motor.

Further, the tension roller forms an obtuse angle with the wrapping film and the rotating ring along a tangent line.

Compared with the prior art, the utility model discloses a beneficial technological effect:

the utility model discloses a tensioning device for film winder is through installing the tensioning roller for after the tensioning roller was walked around to the film, the twine is on article again. In the whole process, the motor drives the roller to rotate, the roller drives the article to revolve, and the winding film and the tensioning roller rotate under the action of the film, so that the article is sealed and packaged. In the rotation process of the tension roller, when the tension roller is stressed unevenly, the tension force of the film can be adjusted at any time due to the existence of the spring in the cavity, so that the film is transported with even force, and the sealing effect of the object is improved. In a word, the utility model discloses overspeed device tensioner for film coiler simple structure, the operation of being convenient for guarantees film tensile force homogeneity, improves the sealed quality of article.

Detailed Description

As shown in fig. 1-2, a tensioning device for a film winding machine comprises a base 1, a rotatable rotating ring 3 is mounted at the upper end of the base 1, a plurality of rollers 4 are frictionally contacted with the outer periphery of the rotating ring 3, the number of the rollers 4 is five, and the rollers are centrally and symmetrically distributed around the rotating ring 3. The roller 4 is connected with a motor 2, the motor 2 is located at the bottom of the base 1, and the motor 2 is specifically a direct-current speed reduction motor. The motor 2 drives the roller 4 to rotate, and the roller 4 gives friction force to the rotating ring 3, so that the rotating ring 3 rotates.

And a winding film 5 is arranged at the upper end of the base 1 close to the middle of the outer side of the rotating ring 3, and the winding film 5 can rotate relative to the base 1 and can rotate in the winding process of the winding film. Adjusting devices 7 are symmetrically arranged at the left end and the right end of the upper end face of the base 1, the adjusting devices 7 are located on the outer side of the rotating ring 3, and clamping devices 6 which are centrosymmetric are arranged on the two adjusting devices 7. The adjusting device 7 is used for adjusting the position of the clamping device 6 according to the requirement of the article. The clamping device 6 is used for clamping an article, ensures the stability of the article along with the operation of the rotating ring 3 and improves the film sealing quality.

The upper end of base 1 is close to install tensioning roller 8 on the side of winding membrane 5, tensioning roller 8 installs on support 9 through pivot 10, support 9 installs on base 1. The tension roller 8 forms an obtuse angle with the winding film 5 and the rotating ring 3 along a tangent line. As shown in fig. 3-4, a cavity 8-1 is formed in the tensioning roller 8, and a plurality of springs 8-2 are equidistantly distributed on the inner circumference of the cavity 8-1. The film is wound around the tensioning roller 8 and then is sealed, in the process, once the tensioning force on the uniform vertical surface is inconsistent, the tensioning roller 8 is inwards concave due to the large-force part, the conveying distance of the film is adjusted in a small range, and meanwhile, the output uniformity of the tensioning force is realized under the action of the spring 8-2, so that the sealing performance of the film wound on the article is improved.
