The top end of the main shaft is fixedly connected to a motor, and the lower surface of the motor is fixedly connected to the top surface of the mixing tank. The plaster raw material is added into the mixing tank through a feeding pipe, and the heating furnace is started. The heating furnace heats the mixing tank to melt the plaster raw material. The motor is then started. The motor drives the main shaft to rotate, and the main shaft drives the transmission connecting plate to rotate. The transmission connecting plate drives the transmission rod to rotate in a circle. The transmission rod then pushes the stirring plate to rotate in a circle along the axis of the main shaft. When the stirring plate rotates in a circle, the plaster raw material in the mixing tank is stirred. The rotation of the transmission connecting plate drives the reciprocating screw to rotate. The reciprocating screw drives the groove nut to move back and forth up and down. The groove nut drives the transmission sleeve to move back and forth up and down.

When the stirring plate reciprocates up and down, it drives the clamping transmission member to reciprocate up and down, and the clamping transmission member drives the annular lifting plate to reciprocate up and down. The annular lifting plate then drives the annular scraper to reciprocate up and down through the telescopic elastic rod. When the annular scraper reciprocates, it scrapes off the plaster raw materials adhered to the inner wall of the mixing tank. When the annular scraper reciprocates up and down, it drives the slide groove frame to reciprocate up and down, and the slide groove frame drives the telescopic elastic rod The second and telescopic triangular plate move reciprocatingly up and down, and the telescopic triangular plate contacts the inclined surface of the trapezoidal resistance block when moving upward.

[0009] The present invention adopts the above technical solution to bring the following beneficial effects: 1. The plaster mixing device used in the production of the plaster patch stirs the plaster raw materials in the mixing tank when the stirring plate rotates in a circle, which improves the fluidity of the plaster raw materials after melting, thereby making the plaster raw materials mixed more evenly.

The annular scraper vibrates and shakes off the plaster raw materials adhering to the annular scraper after scraping, thereby further improving the completeness of the plaster mixing.

[0011] 3. In the plaster mixing device used in the production of the plaster patch, the zirconium oxide powder enters the heating furnace through the feeding pipe, which improves the heating efficiency of the heating furnace and reduces the energy consumption of the heating furnace, so that the device has a better heating effect on the plaster raw materials and promotes the mixing quality of the plaster. After the sliding cover plate covers the limiting convex plate and the feeding pipe, the zirconium oxide powder cannot enter the heating furnace, so that the zirconium oxide powder enters the heating furnace intermittently, and then the temperature of the heating furnace rises in a step-by-step manner, so that the plaster raw materials are heated more evenly, further promoting the mixing quality of the plaster.

9. A mixing method of a plaster mixing device for producing a plaster patch, using the plaster mixing device for producing a plaster patch according to claim 8, characterized in that: The following steps are involved: Step 1: First, add the plaster raw material into the mixing tank (1) through the feeding pipe (3), start the heating furnace (2), and the heating furnace (2) heats the mixing tank (1) to melt the plaster raw material; Step 2: Then, the motor is started, the motor drives the main shaft (5) to rotate, and the main shaft (5) drives the transmission connecting plate (51) to rotate; Step 3: Subsequently, the transmission connecting plate (51) drives the transmission rod (52) to rotate in a circle, and the transmission rod (52) then drives the stirring plate (53) to rotate in a circle along the axis of the main shaft (5); Step 4: Finally, the stirring plate (53) stirs the plaster raw materials in the mixing tank (1) while rotating in a circular motion, so that the plaster raw materials are evenly mixed; Step 5: The transmission connecting plate (51) rotates to drive the reciprocating screw (54) to rotate, the reciprocating screw (54) drives the groove nut (56) to move back and forth up and down, the groove nut (56) drives the transmission collar (57) to move back and forth up and down, the transmission collar (57) drives the stirring plate (53) to move back and forth up and down, and because the transmission collar (57) and the groove nut (56) are rotatably connected, the stirring plate (53) can move back and forth up and down while rotating; Step 6: When the stirring plate (53) moves up and down reciprocatingly, the clamping transmission member (65) drives the annular lifting plate (62) to move up and down reciprocatingly. When the annular lifting plate (62) moves up and down reciprocatingly, the lifting inclined plate (79) is driven to move up and down reciprocatingly. When the lifting inclined plate (79) moves upward, it pushes the transmission inclined plate (78) to move backward through the guidance of the inclined surface. The transmission inclined plate (78) drives the push rod (77) to move backward. The push rod (77) drives the push plate (76) to move backward. The push plate (76) then drives the sliding cover plate (75) to slide backward in the medicine adding box (71), so that the sliding cover plate (75) is away from the limiting convex plate (74). Step 7: At this time, the feed pipe (73) is exposed, and the zirconium oxide powder can enter the heating furnace (2) from the feed pipe (73). When the transmission inclined plate (78) descends, the transmission inclined plate (78) loses the resistance of the lifting inclined plate (79). At this time, the elastic restoring action of the return spring (710) pulls the push plate (76) and the push rod (77) to move forward and reset. The push plate (76) then drives the sliding cover plate (75) to move forward and reset and cover the limiting convex plate (74) and the feed pipe (73). At this time, the zirconium oxide powder cannot enter the heating furnace (2), thereby allowing the zirconium oxide powder to intermittently enter the heating furnace (2).
