[0002] TPR material is a thermoplastic rubber material. It is a kind of thermoplastic soft rubber material with rubber elasticity and does not require vulcanization, and can be directly processed and formed (such as injection molding, extrusion, blow molding, etc.). TPR material is based on thermoplastic styrene-butadiene rubber as the basic raw material, and is blended and modified with resin, filler, plasticizing oil agent and other functional additives. In the process of making TPR material, a mixing device is needed to mix and stir the above-mentioned various materials.
[0003] In the process of making TPR material, a mixing device is needed to mix and stir the above-mentioned various materials. Before production, the proportions of the raw materials need to be accurately calculated. After calculation, different raw materials need to be mixed and prepared according to the proportions. However, in the actual stage of making TPR material, due to the inconvenient opening and closing of the feeding end of the stirring device, it is usually necessary to weigh all TPR raw materials one by one in advance, and then add them to the stirring device at one time. If the staff finds that the raw material ratio is unreasonable or a certain raw material is missing, the stirring device needs to be shut down, and the convenience of use is poor.
[0004] Therefore, a stirring device for TPR gas pipe raw materials used in production is proposed, which has the advantage of online feeding, and thus solves the problems in the above background art. Summary of the Utility Model

[0022] Now, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments. As Figures 1-3 shown, a stirring device for raw materials of TPR gas pipes for production according to an embodiment of the present invention includes a support frame 1 and a stirring cylinder 4. Two supports 2 are welded on the support frame 1, and a stirring cylinder 4 is arranged between the two supports 2. A feed nozzle 6 is welded to the left end of the stirring cylinder 4, and an end shaft 9 is welded to the right end of the stirring cylinder 4. The feed nozzle 6 and the end shaft 9 are respectively rotatably connected to the two supports 2 through bearings. A fixing frame 3 is fixedly installed on the left side of the support frame 1 by bolts. A feed hopper 7 is welded to the upper surface of the fixing frame 3, and a horn mouth 15 is welded to the bottom of the feed hopper 7. A bushing 16 is arranged corresponding to the horn mouth 15 on the upper right side of the fixing frame 3, and the inner ring of the bushing 16 is rotatably connected to the outer wall of the feed nozzle 6 through a ball bearing. A motor 11 is fixedly installed on the right side of the support frame 1, and a transmission belt 10 is wound around the output end of the motor 11.

An arc shell 12 is welded at the discharge port opened in the middle of the stirring cylinder 4, and a discharge horn 13 is welded to the surface of the arc shell 12 corresponding to the discharge port of the stirring cylinder 4. An arc baffle 14 is inserted and installed on the side surface of the arc shell 12, and the concave surface of the arc baffle 14 fits the discharge port of the stirring cylinder 4. A plurality of stirring columns 5 are welded on the inner wall surface of the stirring cylinder 4. The control mode of the motor 11 of the present invention is controlled by manually starting and closing the switch. The wiring diagram of the power element and the power supply are common knowledge in the art. And the present invention mainly protects mechanical devices, so the control mode and wiring layout will not be further explained in the present invention. Among them, the setting of the bushing 16 is conducive to the positioning during the installation stage of the feed hopper 7, and the ball bearing built in the bushing 16 is used to keep connected with the rotating feed nozzle 6;
[0023] In one embodiment, a support frame 17 is welded to one end of the arc-shaped baffle 14 extending out of the arc-shaped shell 12. A threaded column 18 is connected in the support frame 17 through a shaft seat. A threaded sleeve 19 is screwed onto the surface of the threaded column 18. A contact block 20 is fixedly connected to the part of the threaded sleeve 19 extending out of the support frame 17. A positioning groove 22 is formed on the outer wall surface of the arc-shaped shell 12. A positioning column 21 is welded to the surface of the contact block 20 facing the arc-shaped shell 12, and the positioning column 21 extends into the positioning groove 22 on the outer wall of the arc-shaped shell 12. By inserting the arc-shaped baffle 14 into the arc-shaped shell 12 from left to right, the arc-shaped baffle 14 can block the discharge port in the middle of the mixing cylinder 4, which is conducive to the mixing of TPR raw materials. Then, rotate the threaded column 18 arranged in the support frame 17, so that the threaded sleeve 19 drives the contact block 20 to contact the outer wall of the arc-shaped shell 12 during the movement along the surface of the threaded column 18, so that the positioning hole block on the contact block 20 extends into the positioning groove 22 formed on the outer wall surface of the arc-shaped shell 12, so as to lock the arc-shaped baffle 14 inserted into the arc-shaped shell 12.

Through the arrangement of the hot air pipe 8, it is easy to introduce hot air into the mixing cylinder 4, so as to achieve the purpose of heating while mixing the TPR raw materials, which provides convenience for the subsequent extrusion production of TPR gas pipes.
[0027] In one embodiment, the concave surface of the arc-shaped baffle 14 fits the outer wall of the mixing cylinder 4, and a strip-shaped opening is formed in the side of the support frame 17 of the arc-shaped baffle 14 corresponding to the threaded sleeve 19.
