[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a high-efficiency mixing and stirring device for the production of rigid polyvinyl chloride (PVC) sheets. (Refer to...) Figure 1 and Figure 5A high-efficiency mixing and stirring device for the production of rigid polyvinyl chloride sheets includes a mixing tank 1, a support column 2 fixedly connected to the bottom of the mixing tank 1, the number of support columns 2 being four, a closable discharge port provided at the bottom of the mixing tank 1, an inclined stirring mechanism 3 provided at the top of the mixing tank 1, a rotating mechanism 4 provided on the surface of the inclined stirring mechanism 3, and an adjustment mechanism 5 provided on one side of the mixing tank 1.

[0026] The inclined stirring mechanism 3 includes a first motor 301, which is located at the top of the stirring tank 1. The output end of the first motor 301 is fixedly connected to a rotating rod 307. The inner cavity of the rotating rod 307 is movably connected to a rotating rod 302. The surface of the rotating rod 302 is fixedly connected to a movable ball 303. The surface of the movable ball 303 is movably connected to a support block 304. The surface of the rotating rod 302 is fixedly connected to a stirring rod 305. There are four stirring rods 305, which are located in the inner cavity of the stirring tank 1.

[0027] Reference Figure 2 A guide plate 306 is fixedly connected to the bottom of the inner cavity of the mixing tank 1. The guide plate 306 is set at an angle. The guide plate 306 guides the material in the inner cavity of the mixing tank 1, so that the material can slide into the center of the inner cavity of the mixing tank 1 through the angle of the guide plate 306 and slide out smoothly when the discharge port is opened.

[0028] Reference Figure 2 The rotating mechanism 4 includes a second motor 404. The surface of the second motor 404 is fixedly connected to the surface of the rotating rod 307. The output end of the second motor 404 passes through the rotating rod 307 and is fixedly connected to a drive gear 401. The surface of the drive gear 401 is meshed with a driven gear 402. The inner cavity of the driven gear 402 is fixedly connected to the surface of the rotating rod 302. By setting the drive gear 401, the driven gear 402 and the second motor 404 to work together, the drive gear 401 can be driven to rotate by working, and the drive gear 401 can drive the driven gear 402 to rotate, which in turn drives the rotating rod 302 and the stirring rod 305 to rotate, thereby improving the mixing effect of the material in the inner cavity of the mixing tank 1.

[0029] Reference Figure 2 A bearing 403 is fixedly connected to the surface of the rotating rod 302. The outer ring of the bearing 403 is fixedly connected to the surface of the rotating rod 307. The bearing 403 limits the position of the rotating rod 302 to prevent the rotating rod 302 from shaking during rotation or movement.

[0030] Reference Figure 2The adjusting mechanism 5 includes a support rod 502, the bottom of which is fixedly connected to the surface of the mixing tank 1. A cylinder 501 is fixedly connected to the surface of the support rod 502. A connecting rod 503 is fixedly connected to the telescopic end of the cylinder 501. A movable rod 504 is fixedly connected to the surface of the connecting rod 503. A support plate 509 is fixedly connected to the surface of the movable rod 504. The top of the support plate 509 is movably connected to the surface of the first motor 301, and the inner cavity of the support plate 509 is movably connected to the output end of the first motor 301. By setting the cylinder 501, connecting rod 503, movable rod 504, and support plate 502, the adjustment mechanism 5 achieves the desired effect. When used in conjunction with cylinder 501, the connecting rod 503 moves up and down, which in turn moves the movable rod 504 and the support plate 509, ultimately moving the first motor 301 and the parts connected to its output. Since the opening of the movable groove 308 on the surface of the support block 304 is smaller than the diameter of the movable ball 303, the movable ball 303 will not detach from the inner cavity of the support block 304. Therefore, when the first motor 301 moves, it can indirectly cause the inner cavity of the bucket cover 505 to detach from or contact the surface of the mixing bucket 1, thereby sealing or opening the opening of the mixing bucket 1.

[0031] Reference Figure 3 The surface of the support block 304 is provided with a movable groove 308. The inner cavity of the movable groove 308 is movably connected to the surface of the movable ball 303. The movable groove 308 is provided so that the opening of the movable groove 308 is smaller than the diameter of the movable ball 303, thus limiting the position of the movable ball 303 and preventing the movable ball 303 from detaching from the inner cavity of the support block 304 when the inner cavity of the support block 304 rotates.

[0032] Reference Figure 4 The bottom of the support block 304 is fixedly connected to the bucket cover 505. The surface of the bucket cover 505 is provided with a snap-fit ​​groove 506. The inner cavity of the snap-fit ​​groove 506 is movably connected to the surface of the mixing bucket 1. Through the bucket cover 505 and the snap-fit ​​groove 506, when the bucket cover 505 moves to the point where the inner cavity of the snap-fit ​​groove 506 contacts the surface of the mixing bucket 1, the opening of the mixing bucket 1 is sealed.

[0033] Reference Figure 5 The inner cavity of the support rod 502 is provided with a dovetail groove 507, and a dovetail block 508 is movably connected to the inner cavity of the dovetail groove 507. The surface of the dovetail block 508 is fixedly connected to the surface of the movable rod 504. Through the setting of the dovetail groove 507 and the dovetail block 508, the movable rod 504 plays a limiting and guiding role when sliding in the inner cavity of the support rod 502, thereby improving the stability of the movable rod 504 sliding in the inner cavity of the support rod 502.

[0034] Working Principle: When it is necessary to stir and mix the PVC sheets and additives inside the mixing tank 1, the cylinder 501 first starts working. The telescopic end of the cylinder 501 drives the connecting rod 503 to move upward, which in turn drives the support plate 509 to move. The support plate 509 indirectly drives the first motor 301 and the mechanism connected to the output end of the first motor 301 to move. Since the opening of the movable groove 308 in the inner cavity of the support block 304 is smaller than the diameter of the movable ball 303, the movable ball 303 will not detach from the inner cavity of the support block 304. Therefore, the support plate 509 can indirectly drive the support block 304 to move upward, thereby causing the inner cavity of the tank cover 505 to detach from the surface of the mixing tank 1. At this time, the PVC sheets and additives can be placed into the inner cavity of the mixing tank 1. Then, the telescopic end of the cylinder 501 begins to retract inward, indirectly causing the inner cavity of the tank cover 505 to re-contact the surface of the mixing tank 1, thereby stirring the mixing tank. The top of mixing tank 1 is sealed. At this time, the first motor 301 starts working, driving the rotating rod 307 to rotate through the output end of the first motor 301. The rotating rod 307 drives the rotating rod 302 to move, and the rotating rod 302 drives the movable ball 303 to rotate in the inner cavity of the support block 304. At the same time, the rotating rod 302 drives the stirring rod 305 to rotate, stirring the material in the inner cavity of mixing tank 1. Simultaneously, the second motor 404 starts working, driving the drive gear 401 to rotate through the output end of the second motor 404. The teeth on the surface of the drive gear 401 mesh with the teeth on the surface of the driven gear 402, thereby driving the driven gear 402 to rotate. The driven gear 402 drives the rotating rod 302 to rotate, and at the same time drives the movable ball 303 and the stirring rod 305 to rotate around the rotating rod 302 as the axis. The rotation of the stirring rod 305 can improve the mixing effect of the material inside mixing tank 1. After mixing is completed, the discharge port of mixing tank 1 can be opened for discharge.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
