The ends of the two groups of limiting sliders 8 are fixed with a mounting top frame 2, and the lateral longitudinal section of the mounting top frame 2 is set to an inverted U shape.

[0030] Please refer to the attached figure in the instruction manual Figure 1 and 2 A threaded component is fixed on the top wall of the mounting frame 2, and the threaded component includes a threaded tube 14, which is fixedly embedded on the top wall of the mounting frame 2. A screw 1 that penetrates the threaded tube 14 is threaded through the inner cavity of the threaded tube 14, and the bottom wall of the screw 1 is rotatably connected with a scraping plate 3 through a bearing. A handle 13 is fixed on the top wall of the screw 1, and mounting vertical rods 4 are installed on both sides of the bottom wall of the scraping plate 3. Collection frames 5 are installed on the bottom walls of the two groups of mounting vertical rods 4, and the top of the collection frame 5 is set to be open.

[0031] The molten raw material is laid on the top wall of the mounting base 10, and then the handle 13 is rotated to drive the screw 1 to rotate. Under the action of the threaded tube 14, the screw 1 drives the scraper plate 3 to move downward during the rotation until there is a gap of appropriate spacing between the bottom wall of the scraper plate 3 and the top wall of the mounting base 10. Then, the mounting top frame 2 is pushed to drive the limiting slider 8 to move horizontally in the inner cavity of the limiting slide groove 9, so that film processing can be carried out and the thickness of the film can be adjusted conveniently. During the scraping operation, the scraper plate 3 moves horizontally and automatically flows the excess molten raw material on the top wall of the mounting base 10 into the inner cavity of the collecting frame 5 for collection, so as to facilitate its subsequent recycling.

[0032] Please refer to the attached figure in the instruction manual Figure 1 , 2 And 3, multiple groups of limiting vertical tubes 17 are evenly fixed on the top wall of the scraper plate 3, and the multiple groups of limiting vertical tubes 17 are arranged on the outer side of the screw 1.

When the scraping plate 3 moves up and down, the scale rod 11 can be driven to move up and down, so that the scale rod 11 and the reading ring 12 move relative to each other. Under the action of the reading concave hole 18, it is convenient for the staff to check the scale value on the scale rod 11, and it is convenient to grasp and read the distance that the scraping plate 3 moves downward in real time, so as to control the vertical spacing value between the scraping plate 3 and the mounting base 10 and the thickness of the film.

A control valve is installed outside the discharge pipe 6. Under the action of the wedge-shaped structure of the guide block 7, the collected molten raw materials are conveniently accumulated near the discharge pipe 6. Then, the control valve on the discharge pipe 6 is opened so that the molten raw materials can be discharged, which is convenient for recycling.

[0036] Working principle: When using the pressure regulating equipment for the scraper machine, first install the mounting frame 10 at an appropriate position on the main body of the scraper machine, then lay the molten raw material on the top wall of the mounting frame 10, and then twist the handle 13 to drive the screw 1 to rotate. Under the action of the threaded tube 14, the screw 1 drives the scraper plate 3 to move downward during the rotation until there is a gap of appropriate spacing between the bottom wall of the scraper plate 3 and the top wall of the mounting frame 10, and then push the mounting top frame 2 to drive the limiting slider 8 to move horizontally in the inner cavity of the limiting slide groove 9, so that film processing can be carried out and the thickness of the film can be adjusted conveniently.

[0037] During the scraping operation, the scraping plate 3 moves horizontally and automatically flows the excess molten raw material on the top wall of the mounting base 10 into the inner cavity of the collecting frame 5 for collection, so as to facilitate its subsequent recycling. Under the action of the wedge-shaped structure of the guide block 7, the collected molten raw material is conveniently accumulated near the discharge pipe 6, and then the control valve on the discharge pipe 6 is opened to allow the molten raw material to be discharged, so as to facilitate its recycling. When the scraping plate 3 moves up and down, it can drive the limiting vertical rod 15 to move relative vertically in the inner cavity of the limiting vertical pipe 17, so that the spring 16 can be stretched and contracted to produce elastic deformation, thereby limiting the moving path of the scraping plate 3.

[0038] When the scraper plate 3 moves up and down, it can drive the scale rod 11 to move up and down, so that the scale rod 11 and the reading ring 12 move relative to each other. Under the action of the reading recessed hole 18, the staff can conveniently check the scale value on the scale rod 11, and conveniently grasp and read the distance moved downward by the scraper plate 3 in real time, thereby facilitating the control of the vertical spacing value between the scraper plate 3 and the mounting base 10 and the thickness of the film.
