[0002] UV thermal transfer film is a material specially used in thermal transfer technology. It combines the advantages of ultraviolet curing technology and thermal transfer technology. It is mainly used in printing, packaging, advertising and handicrafts. It can achieve high-quality image transfer effects. In the production process of UV transfer film, it is usually necessary to conduct quality inspections on the produced film, such as testing the adhesion of the transfer film.

The upper part of the outer periphery of the storage barrel 11 is fixedly connected with a feed port 14, and the feed port 14 is communicated with the inner wall of the storage barrel 11. The lower part of the storage barrel 11 is rotatably connected with a roller brush 13. The rear side of the top wall of the turntable 6 is fixedly connected with an electric push rod 2 19, and the output end of the electric push rod 2 19 passes through the turntable 6 and is fixedly connected to a fixed plate 15. Both sides of the fixed plate 15 are rotatably connected with a winding roller 16, and a tape 17 is sleeved on the outer periphery of the winding roller 16 on one side. One end of the tape 17 is connected to the winding roller 16 on the other side. The outer periphery of the rear end of the two winding rollers 16 is threadedly connected with a positioning piece 18, and the front ends of the two positioning pieces 18 abut against the rear wall of the tape 17. A drive motor 2 12 is fixedly connected to one side of the front wall of the fixed plate 15, and the output end of the drive motor 2 12 is connected to the winding roller 16.

[0024] When the thermal transfer film needs to be inspected, the staff can first place the thermal transfer film on the upper surface of the base 1 and on the lower side of the turntable 6, and then control the electric push rod 3 to start and drive the turntable 6 fixed at the output end to move downward through the controller 26. When the turntable 6 moves downward, the connected storage barrel 11 can be driven downward, so that the roller brush 13 at the lower part of the storage barrel 11 can abut against the thermal transfer film, and then start the driving motor 7 to drive the gear 8 fixed at the output end to rotate. When the gear 8 rotates, it can drive the gear 2 9 engaged on one side to rotate. When the gear 2 When the connecting rod 10 is rotated, it drives the connecting rod 10 fixed at the bottom to rotate. When the connecting rod 10 rotates, it drives the storage barrel 11 fixed at the bottom and the roller brush 13 at the lower part of the storage barrel 11 to rotate. Since the staff can pour alcohol into the storage barrel 11 through the feed port 14, the alcohol entering the storage barrel 11 will contact the roller brush 13 through the capillary of the inner bottom wall and make the roller brush 13 absorb the alcohol. Therefore, when the roller brush 13 rotates, alcohol can be applied to the surface of the thermal transfer film to detect the state of the thermal transfer film after contacting the alcohol. At the same time, the electric push rod 1 can be activated. 9 drives the fixed plate 15 fixed at the output end to move downward. When the fixed plate 15 moves downward, it will drive the winding roller 16 and the adhesive tape 17 to move downward. When the adhesive tape 17 contacts the thermal transfer film, the portion of the thermal transfer film that is not coated with alcohol can be pasted. Then the electric push rod 2 19 is reset to drive the fixed plate 15 to move upward and tear off the adhesive tape 17. The adhesion test can be performed by repeatedly pasting. When the alcohol application is completed, the electric push rod 2 19 can be reset and the electric push rod 1 3 can be moved upward so that the roller brush 13 is slightly raised to cancel the contact with the thermal transfer film. Then the servo motor 5 can be driven The turntable 6 rotates, and when the turntable 6 rotates, the adhesive tape 17 can be driven to move above the alcohol-applied area. At this time, by starting the drive motor 2 12, the winding roller 16 on one side can be driven to rotate, so that the adhesive tape 17 can be wound up. Then, the electric push rod 2 19 is started again to perform an adhesion test on the area after the alcohol is applied, and then the film can be tested for alcohol, and the adhesion of the film before and after contact with alcohol can be tested respectively. At the same time, by providing a positioning member 18, the positioning member 18 can be assembled and disassembled to achieve the replacement of the adhesive tape 17.

[0025] Reference Figure 1 、 Figure 4 and Figure 5The middle part of the front wall of the base 1 is fixedly connected to a fixed frame 21, and both sides of the top wall of the fixed frame 21 are fixedly connected to a cylinder 22. The output ends of the two cylinders 22 pass through the inner top wall of the fixed frame 21 and are fixedly connected to the movable plate 2 at both ends. The movable plate 2 is slidably connected to the inner wall of the base 1, and the bottom wall of the movable plate 2 is fixedly connected to a plurality of pressure rods 24. The plurality of pressure rods 24 are evenly distributed in a ring shape. One side of the inner wall of the plurality of pressure rods 24 is rotatably connected to one end of a rotating shaft 27, and the other end of the plurality of rotating shafts 27 are rotatably connected to the other side wall of the pressure rod 24. The middle part of the plurality of rotating shafts 27 is fixedly connected to a connecting rod 25, and the bottom ends of the plurality of connecting rods 25 are lower than the bottom end of the pressure rod 24, and the two side walls of the plurality of connecting rods 25 are rotatably connected to the rollers 23. The upper parts of the two side walls of the plurality of connecting rods 25 are fixedly connected to one end of a torsion spring 20, and the other ends of the plurality of torsion springs 20 are fixedly connected to the inner wall of the pressure rod 24, and the plurality of torsion springs 20 are arranged on the outer periphery of the rotating shaft 27.

[0026] When the cylinder 22 drives the movable plate 2 fixed at the output end to move downward, the movable plate 2 moves downward, and the pressure rods 24 fixed to the bottom wall of the movable plate 2 move downward. When the pressure rods 24 move downward, the corresponding connecting rods 25 move downward and contact the thermal transfer film. Then, as the pressure rods 24 continue to move downward, downward pressure is applied to the connecting rods 25, thereby pushing the multiple connecting rods 25 to rotate outward with the corresponding connected rotating shafts 27 as the axis, thereby tightening the abutting thermal transfer film, and reducing friction under the action of the roller 23, reducing damage to the thermal transfer film when the connecting rods 25 move, and pulling the torsion spring 20 when the connecting rods 25 rotate outward. Therefore, when the cylinder 22 drives the movable plate 2 to reset, the connecting rods 25 can be reset under the action of the torsion spring 20, thereby smoothing the thermal transfer film before detection, ensuring the accuracy of detection.

[0027] Working principle: During actual use, the thermal transfer film can be placed on the upper surface of the base 1, and the storage barrel 11 is driven downward by starting the electric push rod 3 and the roller brush 13 is brought into contact with the thermal transfer film. Then, the drive motor 7 is started to drive the roller brush 13 to rotate and apply alcohol to the surface of the thermal transfer film to detect the state of the film after contact with alcohol. While applying, the electric push rod 2 19 is started to drive the fixed plate 15 and the tape 17 to move downward and stick the part of the thermal transfer film that is not coated with alcohol. Then, the electric push rod 2 19 drives the fixed plate 15 to move upward and pulls off the tape 17 for adhesion detection. When the electric push rod 1 3 is reset, the servo motor 5 can drive the turntable 6 to rotate and move the tape 17 above the alcohol-applied area, so that the adhesion of the area after alcohol application can be detected again, and then the film can be tested for alcohol, and the adhesion of the film can be detected separately before and after contact with alcohol.

[0028] In addition, before the inspection, the cylinder 22 can drive the movable plate 2 and the pressure rod 24 fixed to the bottom wall of the movable plate 2 to move downward. When the pressure rod 24 moves downward, it will drive the connecting rod 25 to move downward and contact the thermal transfer film. The continued downward movement of the pressure rod 24 will push the connecting rod 25 to rotate outward with the rotating shaft 27 as the axis and tighten the thermal transfer film, so that the thermal transfer film can be smoothed before the inspection to ensure the accuracy of the inspection.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
