Description

Technical Field

[0001] The utility model relates to the technical field of adhesive film winding, in particular to a traction device capable of taking into account two kinds of adhesive films, one coated with a PE film and the other not coated with a PE film. Background Art

[0002] In the production process of adhesive film, a colloidal substance is coated on the surface of the substrate, and then heated or cured to form an adhesive film. A glue coating device is required for the glue coating production, and the glue coating device is different according to the viscosity of the resin matrix. If the resin viscosity is high (non-sticky), the prepared adhesive film does not need to be covered with a PE isolation film. If the resin viscosity is low (sticky), the prepared adhesive film needs to be covered with a PE isolation film on the surface before it can be rolled up. If it is covered with a PE isolation film, it can be pulled by a pair of rollers, but if it is not covered with a PE isolation film, it cannot be pulled by a pair of rollers due to its high viscosity.

[0003] An existing adjustable traction type film rewinder (Announcement No.: CN220664366U) has the following defects: the above device adopts an adjustable traction mechanism to achieve traction of the film, but still only adopts the roller traction method to pull the film. If the film to be pulled is not covered with a PE isolation film, it is impossible to use the roller for traction, resulting in only the winding mechanism to complete the traction, so that there is no limiting mechanism in the middle section of the traction, resulting in poor final winding quality.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please see attached Figure 1 -Attached Figure 4 A traction device for both PE-coated and non-PE-coated adhesive films comprises an outer bracket 1, a bottom plate is fixed between the supporting legs of the outer bracket 1, a top surface of the outer bracket 1 is rotatably connected with an unwinding roller 15, and an adhesive film is rolled up on the unwinding roller 15, a pair of roller traction mechanisms are arranged on the inner rear side of the outer bracket 1, an adsorption traction mechanism is arranged on the inner front side of the outer bracket 1, and the pair of roller traction mechanisms include cylinders 11 fixed on the top surface of the outer bracket 1 near the left and right sides, a mounting frame 31 is arranged near the rear side of the inner top surface of the outer bracket 1, an upper pressing roller 12 is rotatably connected to the mounting frame 31, and telescopic rods of the two cylinders 11 both penetrate the top surface of the outer bracket 1 and are connected to the mounting frame The top surface of 31 is fixed, and the inner bottom surface of the outer bracket 1 is rotatably connected to the lower rubber roller 13 near the rear side. Two motors and reducers are fixed on the top surface of the bottom plate of the outer bracket 1 near the front and rear sides. The output shaft of the reducer near the rear side of the outer bracket 1 is driven by the lower rubber roller 13 through a sprocket and a chain. Through the setting of the roller traction mechanism, the movable upper pressure roller 12 and the lower rubber roller 13 can cooperate to pull the rubber film with a PE isolation film on the surface. When it is necessary to pull the rubber film without a PE isolation film on the surface, the upper pressure roller 12 and the lower rubber roller 13 can be driven to separate, and then the rubber film without a PE isolation film on the surface can be adsorbed and pulled by the adsorption traction mechanism.

[0022] In the embodiment, the adsorption and traction mechanism includes a driven roller 21 rotatably connected to the inside of the outer bracket 1, the driven roller 21 is located directly in front of the lower rubber roller 13, and the inside of the outer bracket 1 near the front side is rotatably connected to a main drive roller 24. The output shaft of the reducer near the front side of the outer bracket 1 is transmitted to the main drive roller 24 through a sprocket and a chain. A breathable felt 27 is also provided inside the outer bracket 1, and the breathable felt 27 wraps the driven roller 21 and the main drive roller 24 respectively.

[0023] In the embodiment, a vacuum adsorption box 23 is fixed inside the outer bracket 1 between the driven roller 21 and the main driving roller 24, and the air suction port end of the vacuum adsorption box 23 is connected to a vacuum suction cup 22, and a plurality of adsorption holes are opened on the vacuum suction cup 22. The vacuum suction cup 22 is in contact with the inner wall of the breathable felt 27, and a vortex air pump 28 is also fixed to the top surface of the bottom plate of the outer bracket 1. One end of the air suction pipe of the vortex air pump 28 is connected to the air outlet end of the vacuum adsorption box 23. By setting the adsorption and traction mechanism and adopting the cooperation between the breathable felt 27 and the vacuum suction cup 22, when the adhesive film whose surface is not covered with PE isolation film is pulled, the adhesive film can be effectively adsorbed and positioned on the surface of the breathable felt 27, which increases the winding quality compared with the traditional traction method of winding alone.

[0024] In the embodiment, linear guide rails 32 are fixed on the front and rear sides of the mounting frame 31 inside the outer bracket 1, and the front and rear sides of the mounting frame 31 are respectively slidably arranged on the linear guide rails 32. Through the setting and use of the linear guide rails 32, the mounting frame 31 can be limited to ensure the parallelism of the upper pressure roller 12 and the lower rubber roller 13 during the up and down movement.

[0025] In the embodiment, the rear side of the outer bracket 1 is rotatably connected to a bending roller 14. Through the setting and use of the bending roller 14, the bending roller 14 is a curved flattening roller. At a suitable curvature and angle, the film can be flattened to increase the winding quality of the film.

[0026] In the embodiment, the inner part of the outer bracket 1 is rotatably connected to a bulging roller 25 near the bottom surface, the bulging roller 25 is located below the air felt 27 and fits with the outer wall of the air felt 27, and the inner part of the outer bracket 1 is also rotatably connected to a redirecting guide roller 26 near the bottom surface, the redirecting guide roller 26 is located inside the air felt 27 and fits with the inner part of the air felt 27. Through the arrangement and use of the bulging roller 25 and the redirecting guide roller 26, the air felt 27 can be limited and stretched, thereby ensuring the stability of the air felt 27 when moving.

[0027] Working principle: When in use, when it is necessary to pull the film with PE isolation film on the surface, the film with PE isolation film on the surface of the unwinding roller 15 passes through the upper pressure roller 12 and the lower rubber roller 13 and extends from the front side of the outer bracket 1, and then the cylinder 11 is started to drive the mounting frame 31, the upper pressure roller 12 and the lower rubber roller 13 to approach each other. In this process, the mounting frame 31 slides on the linear guide rail 32, and then the upper pressure roller 12 and the lower rubber roller 13 press the film against each other. At this time, the motor and the reducer near the rear side of the outer bracket 1 are started to drive the lower rubber roller 13 to rotate, so as to pull the film with PE isolation film on the surface. When it is necessary to pull the film without PE isolation film on the surface, the cylinder 11 is started to drive the mounting frame 31, the upper pressure roller 12 and the lower rubber roller 13 away from each other, and then the unwinding roller 15 is moved away from the upper pressure roller 12 and the lower rubber roller 13. The adhesive film without PE isolation film on the surface passes through between the upper pressure roller 12 and the lower rubber roller 13 and extends from the front side of the outer bracket 1. At this time, the adhesive film without PE isolation film on the surface is in contact with the top surface of the breathable felt 27. Then, the vortex air pump 28 is started to cooperate with the pipeline, vacuum adsorption box 23, vacuum suction cup 22 and the adsorption holes on the vacuum suction cup 22 to form a near vacuum state on the surface of the breathable felt 27 on the vacuum suction cup 22, so that the adhesive film without PE isolation film on the surface is firmly adsorbed on the surface of the breathable felt 27. Then, the motor and reducer close to the front side of the outer bracket 1 are started to drive the main driving roller 24 to rotate, so that the breathable felt 27 moves between the driven roller 21, the main driving roller 24, the bulging roller 25 and the redirecting guide roller 26, thereby pulling the adhesive film without PE isolation film on the surface to move.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
