[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will describe the implementation manners of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] As Figures 1-3 shown, this embodiment provides a plastic raw material mixing device, including: a support frame 100, a tank body 200, and a stirring assembly 300.

[0021] The tank body 200 is horizontally arranged and rotatably installed at both ends on the support frame 100. Both ends of the tank body 200 are provided with openings 201, and in the openings 201 are provided baffles 202 in rotational fit, and the baffles 202 are installed on the support frame 100. The side wall of the tank body 200 is provided with two annular notches 203, and in the notches 203 are provided retaining rings 204 that move along the axis of the tank body 200. During the process of the tank body 200 stirring the raw materials, the retaining rings 204 close the notches 203 to prevent the raw materials from falling from the notches 203; the stirring assembly 300 includes a sleeve 301 rotatably installed inside the tank body 200. The circumferential side of the sleeve 301 is provided with a plurality of stirring rods 302 arrayed along its axis and circumferentially, and outside the sleeve 301 is also provided with a turning plate 303 that rotates around its axis, thereby stirring the raw materials.

[0022] Specifically, both ends of the tank body 200 are provided with gear rings 205, the gear rings 205 are engaged with a driving gear 206, the driving gear 206 is sleeved on a transmission shaft 207, the transmission shaft 207 is rotatably installed on the support frame 100 and connected to the output end of a first power device. By driving the transmission shaft 207 to rotate through the first power device, the tank body 200 is driven to rotate under the engagement of the driving gear 206 and the gear rings 205, thereby driving the raw materials located at the bottom of the tank body 200 to move and reducing the occurrence of the phenomenon of settling to the bottom.

[0023] Specifically, a ring groove 209 is provided outside the notch 203, and the diameter of the ring groove 209 is the same as the diameter of the retaining ring 204. When it is necessary to push out the raw materials in the tank body 200, the retaining ring 204 is fitted into the ring groove 209. The outer wall of the retaining ring 204 is provided with a plurality of convex plates 210, the convex plates 210 are sleeved on a cross bar 211, one end of the cross bar 211 is installed on a connecting block 212, the connecting block 212 is installed on the tank body 200, and a spring 213 is sleeved on the cross bar 211. Both ends of the spring 213 respectively abut against the connecting block 212 and the convex plate 210 and are always in a compressed state. Under the action of the spring 213, the retaining ring 204 always has a tendency to move towards the center of the tank body 200, thereby blocking the notch 203 and preventing leakage during the stirring process.

[0024] Specifically, two push plates 214 are further provided between the notches 203 for abutting against the convex plates 210. The push plates 214 are connected to the moving end of a bidirectional linear mechanism. The bidirectional linear mechanism is installed on the support frame 100. By means of the bidirectional linear mechanism, the two push plates 214 can be driven to move away from each other, so as to move the retaining ring 204 out of the notch 203 until the retaining ring 204 is completely located in the annular groove 209, thereby facilitating the complete pouring out of the raw materials in the tank body 200 as soon as possible after the stirring is completed.

[0025] Specifically, a plurality of partition plates 208 are provided on the inner wall of the tank body 200 along the circumferential direction. The partition plates 208 pass through the notches 203. Thus, when the tank body 200 rotates, the partition plates 208 can play a certain supporting role for the raw materials located at the bottom, so as to ensure that the raw materials located at the bottom of the tank body 200 can be successively moved to the upper part and sprinkle downward under the action of gravity, thereby ensuring uniform mixing of the raw materials. Moreover, push rings 215 are provided at both ends of the tank body 200. A plurality of protrusions are provided on the inner side of the push rings 215, and the protrusions cooperate with the partition plates 208. A plurality of connecting rods 216 are provided on the side surface of the push rings 215. The connecting rods 216 penetrate through the tank body 200. After the stirring is completed, the push rings 215 can be driven to move towards the center of the tank body 200 through the connecting rods 216, so as to push the raw materials located at both ends of the tank body 200 to the notches 203 and push them out from the notches 203.

[0026] Specifically, the turning plate 303 is U-shaped and is connected to the rotating ring 304. Both the rotating ring 304 and the sleeve 301 are sleeved on the rotating shaft 305. Both ends of the rotating shaft 305 penetrate through the baffle 202 and are rotatably installed on the support frame 100. One end of the rotating shaft 305 is connected to the output end of a second power device. The second power device is installed on the support frame 100. Driven by the rotating shaft 305, the turning plate 303 and the stirring rod 302 start to rotate synchronously to stir the plastic raw materials.

[0027] Specifically, feed inlets 217 are provided on the baffle plates 202 to facilitate the feeding of raw materials into the tank body 200 during the stirring process.

[0028] Since the above is only a preferred embodiment of the present invention and is not used to limit the present invention, obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
