[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This raw material mixing device for processing polymer plastic materials comprises a first motor, a threaded screw, a movable block, a guide sleeve, clamping plates, a hydraulic push rod, and a lifting arm. The operator starts the first motor to rotate the threaded screw, causing the movable block to move the clamping plates along the guide groove through the threaded engagement of the guide sleeve and the threaded screw. The opposing threads at both ends of the threaded screw allow the two clamping plates to move in opposite directions, thus clamping and fixing the mixing drum. Operation is simple and positioning is easy. Reversing the rotation of the threaded screw allows the mixing drum to be removed from the worktable, and the hydraulic push rod pushes the lifting arm upward, separating the mixing plate from the mixing drum for easy observation and subsequent cleaning and maintenance.

[0014] This raw material mixing device for processing polymer plastic materials includes a second motor, a rotating rod, a stirring plate, a hollow rod, a spring, a connecting rod, and a scraper. The second motor drives the rotating rod to rotate, so that when the hydraulic push rod pulls the lifting arm down, the stirring plate can scrape and stir the raw materials in the mixing tank, causing the rotating rod to enter the mixing tank. During the rotation of the rotating rod, the scraper will scrape off the raw materials adhering to the inner wall of the mixing tank, thereby avoiding residue. The connecting rod slides inside the hollow rod and compresses the spring, so that the scraper can adapt to the inner wall of the mixing tank. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a raw material mixing device for processing polymer plastic materials, including a support frame 1, an anti-slip pad 2 connected below the support frame 1, a worktable 3 connected above the support frame 1, a column 4 connected on the worktable 3, a hollow column 5 connected on the column 4, a guide groove 16 opened on the hollow column 5, a clamping plate 10 sliding in the guide groove 16 and in close contact with the groove wall of the guide groove 16, the contact between the clamping plate 10 and the groove wall of the guide groove 16 allows the guide groove 16 to restrict the clamping plate 10, thereby allowing the clamping plate 10 to move smoothly and avoid tilting.

[0022] A first motor 6 is installed at one end of the hollow column 5. The output shaft of the first motor 6 is connected to a threaded screw 7. Two movable blocks 8 are installed on the threaded screw 7. A guide sleeve 9 is connected to the movable block 8. The threaded screw 7 is rotatably connected inside the hollow column 5. The two ends of the threaded screw 7 are provided with threads in opposite directions. The guide sleeve 9 is threadedly engaged with the threaded screw 7. By rotating the threaded screw 7 through the first motor 6, the two movable blocks 8 drive the two clamping plates 10 to move in opposite directions, thereby clamping and fixing the mixing barrel 22 and preventing the mixing barrel 22 from sliding or tilting during stirring.

[0023] A clamping plate 10 is connected to the movable block 8, and a hydraulic push rod 11 is installed on the column 4. The movable end of the hydraulic push rod 11 is connected to a lifting arm 12. A sliding groove 21 is opened on the lifting arm 12. The sliding groove 21 is concave in shape. The lifting arm 12 is slidably connected to the column 4 through the sliding groove 21. A mixing tank 22 is set on the workbench 3. The lifting arm 12 is moved by pulling or pushing the hydraulic push rod 11, so that the rotating rod 14 can enter or move out of the mixing tank 22. The operation is simple and convenient for staff to inspect and maintain.

[0024] A second motor 13 is installed above the lifting arm 12. The output shaft of the second motor 13 is connected to a rotating rod 14. Multiple hollow rods 17 are connected to the rotating rod 14. Springs 18 are connected inside the hollow rods 17. One end of the springs 18 is connected to a connecting rod 19. The connecting rod 19 slides inside the hollow rods 17 and is connected to a scraper 20 at one end. When the rotating rod 14 rotates, it will drive the scraper 20 to rotate synchronously, thereby scraping the inner wall of the mixing tank 22 through the scraper 20 to avoid the raw materials sticking and remaining. At the same time, the hollow rods 17 and the connecting rods 19 will also stir the raw materials in the mixing tank 22 synchronously to improve the mixing efficiency.

[0025] One end of the rotating rod 14 is connected to multiple stirring plates 15. There are four stirring plates 15 arranged evenly in a centrally symmetrical manner. The bottom of the stirring plates 15 is designed with an inclined surface. The multiple stirring plates 15 at one end of the rotating rod 14 agitate the raw materials in the mixing tank 22, thereby improving the mixing effect of the raw materials in the mixing tank 22.

[0026] The working principle of this utility model is as follows:

[0027] The operator places the mixing drum 22 on the workbench 3, then starts the first motor 6 to rotate the threaded screw 7. The guide sleeve 9 engages with the threaded screw 7, causing the movable block 8 to move the clamping plate 10 along the guide groove 16. The opposing threads at both ends of the threaded screw 7 allow the two clamping plates 10 to move in opposite directions, thus clamping and fixing the mixing drum 22. Then, the second motor 13 is started to rotate the rotating rod 14 and activate the hydraulic push rod 11, which pulls the lifting arm 12 downwards. At this time, the stirring plate 15 scrapes and agitates the raw materials inside the mixing drum 22, causing the rotating rod 14 to enter the mixing drum 22. During the rotation of the rotating rod 14, the scraper 20 scrapes away the raw materials adhering to the inner wall of the mixing drum 22, while the hollow rod 17 and connecting rod 19 simultaneously agitate the raw materials inside the mixing drum 22 to improve mixing efficiency.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
