[0003] According to Chinese Patent No. CN201910513665.5, a decorative film fish scale pattern scraping device is provided. The document includes an outer shell, a coating device and a scraping device fixed inside the outer shell and moved up and down by a first cylinder and a second cylinder respectively, and a control device electrically connected to the coating device and the scraping device. The coating device includes a support plate, a scraper fixed to one side of the support plate, and several paint bottles. The paint bottles are located on the scraper, and the outlet end of the bottom discharge pipe of the paint bottle contacts the upper side of the scraper. The lower end of the scraper is bent towards the support plate. The scraping device includes a support frame, pulleys, a scraper comb, a motor, a drive wheel, and a synchronous belt. The pulleys and the drive wheel are rotatably fixed inside the support frame by a rotating shaft, and the synchronous belt is wound around their outer sides. The pulleys are arranged in two parallel rows, and the pulleys in the front and rear rows are staggered. The first fixing rod on the bottom side of the pulley extends out of the support frame and is connected to one end of the scraper comb. The motor is fixed to the top surface of the top plate of the support frame, and its output shaft is connected to the drive wheel.

[0004] However, the decorative film fish scale pattern scraping device proposed in the document can only scrape out a single texture on the coating layer, which is not convenient to use. Summary of the Invention

It breaks through the limitations of traditional scraping. Through the parallel and equally high slide rod and screw forming a double guide rail structure, and with the motor driving the screw sleeve, it ensures that the scraper moves without deviation and with little vibration, thus improving the uniformity of the scraping.

[0021] 2. The decorative film coating scraping device is driven by an electric push rod to vertically raise and lower the entire lifting plate, quickly adjusting the distance between the scraper and the decorative film to adapt to different coating thicknesses or texture depth requirements.

[0022] 3. This decorative film coating scraping device uses a hollow limiting vertical rod, main body and inner rod as airflow passage, eliminating the need for external pipeline winding. The raising and lowering of the outer rod is controlled by the air pump inflation / deflation. When the air pump is inflating, the outer rod can be used for local scraping and edge scraping. When the air pump is deflating, the scraper is fully raised to avoid accidental contact with uncured coating and reduce the defect rate. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] This invention provides a decorative film coating scraping device, such as... Figure 1-6As shown, it includes a lifting plate 1 and a scraper 9. The lifting plate 1 has a track groove 2 and a drive mechanism for driving the scraper 9 to move along the track groove 2.

[0032] The track groove 2 is set as a curve and is opened along the length direction of the lifting plate 1.

[0033] An electric push rod 3 is fixedly connected to the top of the lifting plate 1, and the electric push rod 3 is mounted on the frame.

[0034] The entire lifting plate 1 is vertically raised and lowered by the electric push rod 3, which quickly adjusts the distance between the scraper 9 and the decorative film to adapt to different thicknesses of coatings or texture depths.

[0035] The drive mechanism includes a screw 6, a slide bar 5, a mounting plate 4, a motor 7, a crossbar 8, a sliding sleeve 16, a threaded sleeve 17, a sliding frame 11, and a limiting vertical rod 10. The mounting plate 4 is fixedly connected to the top of the lifting plate 1. The slide bar 5 and the screw 6 are fixedly connected to each other, and the slide bar 5 and the screw 6 are at the same horizontal height. The sliding sleeve 16 is slidably fitted on the slide bar 5, and the threaded sleeve 17 is threadedly fitted on the screw 6. The motor 7 is fixedly connected to the mounting plate 4, and the output end of the motor 7 is coaxially connected to the screw 6. The two ends of the crossbar 8 are fixedly connected to the sliding sleeve 16 and the threaded sleeve 17, respectively. The sliding frame 11 is slidably fitted on the crossbar 8, and the limiting vertical rod 10 is fixedly connected to the sliding frame 11. The limiting vertical rod 10 passes vertically through the track groove 2 and is fixedly connected to the scraper 9.

[0036] By cooperating with the curved track groove 2 and the limiting vertical rod 10, the scraper 9 is forced to move along a predetermined complex path to achieve customized textures on the decorative film, such as waves and arcs, breaking through the limitations of traditional scraping. The parallel and equally high slide rod 5 and screw 6 form a double guide rail structure, which, together with the motor 7 driving the screw sleeve 17, ensures that the scraper 9 moves without deviation and with little vibration, thus improving the uniformity of the scraping.

[0037] The sliding frame 11 is configured as a U-shaped frame, and the sliding frame 11 has through holes that match the crossbar 8.

[0038] The scraper 9 includes a main body 14 and a scraper bar 15. The main body 14 is horizontally arranged, and its top center is fixedly connected to the limiting vertical bar 10. At least one scraper bar 15 is fixedly connected to the bottom of the main body 14.

[0039] There are three scraper rods 15, one of which is located in the middle of the main body 14, and the other two scraper rods 15 are symmetrically located on both sides of the main body 14.

[0040] Each scraper 15 has a telescopic rod symmetrically arranged on both sides. The telescopic rod includes an outer rod 19 and an inner rod 18. The inner rod 18 is fixedly connected to the main body 14 and slides and seals with the outer rod 19, so that an air cavity is formed inside the outer rod 19. When the air cavity is fully inflated, the bottom end of the outer rod 19 is flush with the bottom end of the scraper 15.

[0041] The inner rod 18, the main body 14 and the limiting vertical rod 10 are all hollow structures and are interconnected. An air pump 13 is fixedly connected to the sliding frame 11. An air pipe 12 is fixedly connected to the output end of the air pump 13, and the air pump 13 is connected to the top of the limiting vertical rod 10 through the air pipe 12. The air pump 13 is connected to the air chamber through the air pipe 12, the limiting vertical rod 10, the main body 14 and the inner rod 18.

[0042] By utilizing the hollow limiting vertical rod 10, the main body 14, and the inner rod 18 as airflow channels, the external pipeline winding is eliminated. The raising and lowering of the outer rod 19 is controlled by the air pump 13 charging / discharging. When the air pump 13 is charging, the outer rod 19 can be locally scratched and the boundary texture can be scratched. When the air pump 13 is de-airing, the scraper 15 is fully raised to avoid accidental contact with uncured coating and reduce the defect rate.

[0043] When the air pump 13 draws air, the air pressure in the air chamber decreases, and the outer rod 19 rises, causing the bottom of the outer rod 19 to move away from the scratch position; when the air pump 13 inflates, the air pressure in the air chamber increases, and the outer rod 19 descends, causing the bottom of the outer rod 19 to press down to the scratch position.

[0044] Working principle: Through the cooperation of the curved track groove 2 and the limiting vertical rod 10, the scraper 9 is forced to move along a predetermined complex path to achieve customized textures on the decorative film, such as waves and arcs, breaking through the limitations of traditional scraping. The parallel and equally high slide rod 5 and screw 6 form a double guide rail structure, which, together with the motor 7 driving the screw sleeve 17, ensures that the scraper 9 moves without deviation and with little vibration, thus improving the uniformity of the scraping.
