[0033] Through the rotation of decontamination roller 10, the adherent on the surface of decorative film in the production process is effectively removed, which avoids that the adherent easily causes visual interference to the detection personnel when the decorative film is detected, avoids that the detection efficiency is reduced due to the increase of the pause frequency of the staff in the detection process; through the movement and rotation of transmission plate 15 and smoothing roller 16, the folding or wrinkling phenomenon of both ends of decorative film in the detection conveying process is prevented, which ensures that the decorative film always passes through the detection area of frame 1 in the flat and flat posture, and avoids that both ends of the decorative film are wound in the folded posture, so as to affect the later use effect.

[0034] In use, one end of the decorative film is wound around the outer wall of the transmission mechanism 3, the decorative film is pulled down to pass the limiting mechanism 4, and then pulled up to contact the outer wall of the top of the conveying roller 2, and the other end is the same, and the decorative film is wound through the other end of the transmission mechanism 3 for detection. At this time, the decorative film passes through the detection area at the top of the frame 1, is irradiated by the lamp group 7, and is convenient for the worker to detect whether the decorative film has defects.

The decorative film in the transmission process promotes the rotating force of the decontamination roller 10, at this time the decontamination roller 10 drives the horizontal rod 9 to rotate and starts to rotate inside the U-shaped plate 8, and the decontamination roller 10 removes the attachments or dirt on the top of the decorative film when rotating.

[0035] According to the above embodiment, the decontamination roller 10 is rotated to effectively remove the attachments on the surface of the decorative film in the production process, so that the attachments do not easily cause visual interference to the detection personnel during the winding and unwinding detection, and the frequency of the worker's pause during the detection process is reduced, thereby improving the detection efficiency.

[0036] Please refer to Figures 1-8 On the basis of the above embodiment, another embodiment of the present application further comprises a flow device 17.

[0037] The flow device 17 comprises a cylinder 171, which is fixedly installed on the outer wall of the hollow ladder plate 12 near one end of the electric rotating lever 11. The cylinder 171 is fixedly installed with a sliding plate 172 away from the other end of the hollow ladder plate 12. The inside of the sliding plate 172 penetrates and is fixedly installed with a negative pressure device 173. The bottom of the negative pressure device 173 is fixedly installed with a collection mechanism 174 through a spiral hose.

[0038] The sliding plate 172 is installed through and slides in the ventilation groove, and is used for ventilation of the back position when detecting. The negative pressure device 173 is used for sucking floating dirt in the detection range. The collecting mechanism 174 is fixedly installed on the back outer wall of the L-shaped plate 5, and provides power for the negative pressure device 173 and concentrates the dirt.

[0039] The L-shaped strip 175 is fixedly installed through the outer wall of the cylinder 171 and is located between the transmission mechanism 3 and the limiting mechanism 4. The fixed rod 176 is fixedly installed on the bottom end of the L-shaped strip 175. The pressing roller 177 is rotatably installed through the outer wall of the fixed rod 176.

[0040] The negative pressure device 173 reciprocatingly sucks up and down, improves the absorption and separation effect of the floating object in the detection area, prevents external dust from adhering to the surface of the decorative film during the detection process, easily confuses the line of sight of the detection personnel, increases the detection difficulty, and affects the cleanliness of the decorative film, thereby reducing the quality of the decorative film. The pressing roller 177 is indirectly pressed downward, without damaging the decorative film, and enhances the tightness of the decorative film during transmission with the two-end transmission mechanism 3, preventing the decorative film from being too soft to adhere to the detection area on the top of the frame 1 during transmission and detection.

[0041] In use, the hollow ladder plate 12 drives the cylinder 171 to move downward and reset. The cylinder 171 pulls the sliding plate 172 to slide downward and reset in the L-shaped plate 5. The sliding plate 172 indirectly opens and accelerates the air flow speed in the detection area. The sliding plate 172 drives the negative pressure device 173 to move synchronously during the movement process. The negative pressure device 173 promotes the deformation of the spiral hose, and generates suction force through the power provided by the collecting mechanism 174. At this time, the negative pressure device 173 absorbs the dirt floating in the detection area of the decorative film up and down. The cylinder 171 moves downward and resets to drive the L-shaped strip 175 to move synchronously. The L-shaped strip 175 drives the fixed rod 176 to move synchronously. The fixed rod 176 drives the pressing roller 177 to move toward the decorative film between the transmission mechanism 3 and the limiting mechanism 4. When the pressing roller 177 contacts the decorative film in the transmission process, a certain friction force is generated. At this time, the pressing roller 177 rotates along the outer wall of the fixed rod 176, so as to press the decorative film without affecting the transmission of the decorative film.

[0042] According to the above embodiment, by reciprocating the negative pressure device 173 up and down, the absorption and separation effect of the floating objects in the detection area is improved, preventing external dust from adhering to the surface of the decorative film during the detection process, which can easily confuse the line of sight of the detection personnel, increase the detection difficulty, and affect the cleanliness of the decorative film, thereby reducing the quality of the decorative film. By indirectly pressing down through the pressing roller 177, the tightness of the decorative film during transmission is enhanced without damaging the decorative film, preventing the decorative film from being too soft and difficult to adhere to the top of the detection area of the frame 1 during transmission and detection.

[0043] Please refer to Figures 1-8 On the basis of the above embodiment, another embodiment of the present application further comprises a fitting device 18.

[0044] The fitting device 18 comprises a U-shaped telescopic frame 181, the bottom of the telescopic end of the U-shaped telescopic frame 181 is fixedly installed at the top edge of the frame 1, the inner wall top of the U-shaped telescopic frame 181 is fixedly installed with a heating mechanism 182, and the side away from the cylinder 171 of the U-shaped telescopic frame 181 is fixedly installed with a heat gathering plate 183.

[0045] The top of the fixed end of the U-shaped telescopic frame 181 is in contact with the inner wall top of the L-shaped strip 175, and the U-shaped telescopic frame 181 is internally provided with a spring, the heating mechanism 182 heats and softens the conveying end of the decorative film, and the heat gathering plate 183 gathers the heat emitted through its arc surface.

[0046] The side close to the cylinder 171 of the U-shaped telescopic frame 181 is fixedly installed with an L-shaped frame 184, the inside of the sliding groove of the U-shaped plate 8 is fixedly installed with a friction cotton block 185, the bottom of the L-shaped frame 184 is hingedly connected with a U-shaped pressing plate 186 through a torsion spring, the inside of the U-shaped pressing plate 186 is fixedly installed at the outer wall of the friction cotton block 185, the bottom of the U-shaped pressing plate 186 is in contact with the top of the U-shaped plate 8, and the bottom of the friction cotton block 185 is in contact with the surface of the decontamination roller 10.

[0047] Through the heating effect of the heating mechanism 182, the decorative film is conveyed in a more soft state, improving the fit between the decorative film and the conveying roller 2, avoiding damage to the decorative film due to poor fit during transmission, and ensuring that the decorative film can be closely detected on the top of the frame 1; the outer wall of the decontamination roller 10 is always in contact with the friction cotton block 185, which quickly removes the dirt attached to the surface of the decontamination roller 10, ensuring that the decontamination roller 10 always contacts the decorative film with a clean surface, preventing the decorative film from being damaged, and the reciprocating friction cotton block 185 speeds up the air circulation in its interior, avoiding the increase of the probability of water vapor breeding in its interior due to heat radiation, and preventing the water vapor from wetting the decorative film.

[0048] In use, when the L-shaped strip 175 moves downward, the fixed end of the U-shaped telescopic frame 181 is pressed to move downward, and then the U-shaped telescopic frame 181 is reset by the spring. The U-shaped telescopic frame 181 drives the heating mechanism 182 to move in the direction of the conveying roller 2. At this time, the heating mechanism 182 performs heating treatment on the decorative film conveyed in the range of the conveying roller 2. Through heat, the decorative film in the bending stage is softened to a certain extent. At the same time, the U-shaped telescopic frame 181 drives the heat collecting plate 183 to move synchronously. The heat collecting plate 183 guides the heat to the direction close to the conveying roller 2 through the curved surface, reducing the heat dissipation loss. The U-shaped telescopic frame 181 drives the L-shaped frame 184 to move downward and reset. When the L-shaped frame 184 moves downward, it touches the U-shaped pressing plate 186 to generate a downward movement force. The bottom of the U-shaped pressing plate 186 is limited by the top of the U-shaped plate 8, so that the hinge shaft of the U-shaped pressing plate 186 generates a rotating force. At this time, the U-shaped pressing plate 186 starts to overturn around the hinge shaft, and the U-shaped pressing plate 186 pushes the friction cotton block 185 in contact with the dirt roller 10 to deform. Then the U-shaped pressing plate 186 is reset by the torsional spring, and the process is repeated.

[0049] According to the above embodiment, the heating effect of the heating mechanism 182 makes the decorative film be conveyed in a more soft form, improves the adhesion between the decorative film and the conveying roller 2, avoids damage to the decorative film due to poor adhesion during conveying, and ensures that the decorative film can be closely attached to the top of the frame 1 for detection. The friction cotton block 185 is always in contact with the outer wall of the dirt roller 10, which quickly removes the dirt attached to the surface of the dirt roller 10, so that the dirt roller 10 always contacts the decorative film with a clean surface, preventing the decorative film from being damaged. At the same time, the reciprocating deformation of the friction cotton block 185 accelerates the air circulation in the interior of the friction cotton block 185, avoids increasing the probability of water vapor breeding in the interior under heat radiation, and prevents the water vapor from wetting the decorative film.

[0050] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
