Adjusting seats 11 are symmetrically fixedly installed on the outside of the adjusting shaft 10, and the bottoms of the two adjusting seats 11 extend to the bottom of the strip frame 9 and are fixedly connected to the top of the tool holder 5. An adjusting motor 12 is fixedly installed at the top inside the frame 7 and is energized by the control switch 8. A rotating sleeve 13 is fixedly installed at the bottom of the output shaft of the adjusting motor 12. A positioning ring 22 is symmetrically rotatably installed on the outside of the rotating sleeve 13 and is fixedly installed inside the frame 7. A rotating support rod 14 is installed inside the rotating sleeve 13. A sliding strip 15 is symmetrically fixedly installed on the outside of the top of the rotating support rod 14. The inner wall of the cylinder is symmetrically provided with sliding grooves 16, and the sliding strip 15 is slidably installed inside the sliding grooves 16.

The bottom of the rotating support rod 14 extends into the inner wall of the strip frame 9. The bottom of the rotating support rod 14 is fixedly installed with an adjusting bevel gear 18. The outer side of the adjusting bevel gear 18 is meshed with a transmission bevel gear 19, and the transmission bevel gear 19 is fixedly installed on the outer side of the adjusting shaft 10. An electric telescopic rod 20 is provided inside the frame 7 and outside the rotating sleeve 13. The electric telescopic rod 20 is energized and connected to the control switch 8. A fixing ring 21 is symmetrically fixedly installed on the outer side of the electric telescopic rod 20, and the fixing ring 21 is fixedly installed inside the frame 7.

[0014] Working Principle: During operation, the mounting plate 1 is first fixed in place using mounting bolts that match the diameter of the mounting hole 2. Then, the control switch 8 activates the electric telescopic rod 20, pushing the strip frame 9 downwards. The strip frame 9 drives the positioning slide rod 24 to slide downwards inside the positioning sleeve, ensuring better stability during movement. Simultaneously, the strip frame 9 drives the rotating support rod 14 to slide downwards inside the rotating sleeve 13 via the positioning bearing 17. The rotating support rod 14 drives the sliding strip 15 to slide inside the sliding groove 16. At the same time, the strip frame 9 drives the adjusting shaft 10 downwards. The adjusting shaft 10 drives the blade holder 5 downwards via the adjusting seat 11. The blade holder 5 drives the scraper body 6 downwards. Once the scraper body 6 has reached the desired position, the electric telescopic rod 20 is stopped, and then the adjusting motor 12 is started. The rotating sleeve 13 rotates inside the two positioning rings 22, ensuring better stability during rotation. Simultaneously, the rotating sleeve 13, through the interaction of the sliding groove 16 and the sliding strip 15, drives the rotating support rod 14 to rotate. The rotating support rod 14 drives the adjusting bevel gear 18 to rotate, which in turn drives the transmission bevel gear 19 to rotate. The transmission bevel gear 19 then drives the adjusting shaft 10 to rotate. The adjusting shaft 10, through the adjusting seat 11, drives the blade holder 5 to move, which in turn drives the scraper body 6 to move. Once the scraper body 6 reaches the desired angle, the adjusting motor 12 stops. This allows the scraper assembly for plastic bag composite film processing to be quickly adjusted during use, improving work efficiency and enhancing practicality.
