Description

Technical Field

[0001] The utility model relates to the technical field of upper auxiliary machines, in particular to an upper auxiliary machine for a rubber internal mixer. Background Art

[0002] The upper auxiliary machine of an internal mixer is an auxiliary device for conveying, weighing and feeding various rubbers and their compound raw materials to the internal mixer. In actual production, due to some storage reasons, some raw materials may agglomerate. The existing upper auxiliary machine can only perform the functions of storage and discharging, but cannot crush the products that are affected by moisture and agglomerate. The agglomerated products will be discharged into the internal mixer together with the normal products, which will affect the quality of the mixed products.

[0003] Therefore, we propose an upper auxiliary machine for a rubber internal mixer. Summary of the Utility Model

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides an upper auxiliary machine for a rubber internal mixer.

[0005] To achieve the above object, the utility model adopts the following technical scheme. An upper auxiliary machine for a rubber internal mixer includes a storage tank body. The top wall surface of the storage tank body is hermetically connected with a feed pipe. The bottom wall surface of the storage tank body is in a conical shape. The bottom wall surface of the storage tank body is hermetically connected with a discharge pipe. A feeding mechanism is arranged on the discharge pipe. A driveable first motor is fixedly installed on the top wall surface of the storage tank body. A vertically arranged transmission rotating rod is rotatably installed inside the storage tank body. A broken stirring rotating rod is fixedly installed on the outer wall of the transmission rotating rod. The output end of the first motor is in transmission connection with the transmission rotating rod. A connecting cylinder and a filter plate are arranged inside the storage tank body. The filter plate is fixedly installed on the outer wall of the connecting cylinder. The connecting cylinder is arranged on the outer wall of the transmission rotating rod. Uniformly distributed screening holes are formed on the upper side wall surface of the filter plate.

[0006] Preferably, the outer wall of the transmission rotating rod movably penetrates through the top wall surface of the connecting cylinder. A fixing rod is fixedly installed on the outer wall of the transmission rotating rod. The fixing rod is in an L shape. A sliding roller is rotatably installed on the upper side wall surface of the vertical end of the fixing rod. A contact block is fixedly installed on the top wall surface inside the cavity of the connecting cylinder.

[0007] Preferably, the outer wall of the sliding roller is in sliding contact with the lower side wall surface of the contact block. The lower side wall surface of the contact block is in an arc shape. The upper side wall surface of the filter plate is in a conical shape with a smaller upper part and a larger lower part.

[0008] Preferably, the feeding mechanism includes a connecting pipe. The connecting pipe is rotatably installed inside the discharge pipe. A spiral conveyor pipe for uniform discharging is hermetically connected to the bottom wall surface of the connecting pipe. A spiral pipe that can rotate is arranged inside the spiral conveyor pipe.

[0009] Preferably, a horizontally arranged mounting bracket is fixedly installed on the outer wall of the discharging pipeline, and a second motor capable of driving is fixedly installed on the upper side wall surface of the mounting bracket.

[0010] Preferably, the output end of the second motor is drivingly connected to a connecting plate, and the vertical end of the connecting plate is fixedly installed on the upper outer wall of the screw conveyor pipe.

[0011] Advantageous Effects

[0012] The utility model provides an upper auxiliary machine for a rubber internal mixer. It has the following advantageous effects:

[0013] (1) For the upper auxiliary machine for a rubber internal mixer, during the use of the utility model, the storage tank body is filled through the feeding pipeline. By starting the first motor, the output end of the first motor drives the transmission rotating rod to rotate, and the stirring rotating rod starts to rotate to stir the products inside the storage tank body. The stirring rotating rod contacts the products and breaks up the agglomerated products to ensure the quality of the products. In addition, the qualified products will pass through the screening holes on the filter plate, fall to the bottom of the storage tank body and be discharged through the discharging pipeline, while the filter plate will block the agglomerated products to further improve the quality of the products.

[0014] (2) For the upper auxiliary machine for a rubber internal mixer, during the use of the utility model, when the transmission rotating rod rotates, the fixed rod will move together with it. The sliding roller will move along the arc surface of the contact block and move away from the contact block. Finally, the sliding roller will contact the top wall surface inside the connecting cylinder cavity. In this way, the sliding roller reciprocally moves closer to or away from the contact block, and the connecting cylinder will drive the filter plate to move up and down, which can reduce the risk of blockage of the screening holes. In addition, by starting the mounting bracket, the output end of the mounting bracket drives the connecting plate to rotate, which can change the horizontal angle of the screw conveyor pipe. Since in actual production, multiple upper auxiliary machine devices are required to supply materials to the internal mixer at the same time. During the installation of the upper auxiliary machine, the left ends of the screw conveyor pipes of multiple upper auxiliary machines need to be connected to the feeding funnel of the internal mixer. If the screw conveyor pipe is not facing the feeding funnel during the installation of the upper auxiliary machine, the whole device needs to be rotated, which is rather inconvenient to operate. Obviously, the above-mentioned way that the screw conveyor pipe can be rotated facilitates the installation process. Description of the Drawings

By turning on the first motor 3, the output end of the first motor 3 will drive the driving rotating rod 4 to rotate, and the stirring rotating rod 5 will start to rotate to stir the products inside the storage tank body 1. The stirring rotating rod 5 will contact the products and break up the agglomerated products to ensure the quality of the products. In addition, the qualified products will fall through the screening holes on the filter plate 7 to the bottom of the storage tank body 1 and be discharged through the discharge pipeline 2, while the filter plate 7 will block the agglomerated products.

[0021] Embodiment 2: On the basis of Embodiment 1, as Figure 1 , Figure 2 and Figure 3 shown, the outer wall of the driving rotating rod 4 movably penetrates through the top wall surface of the connecting cylinder 6. The outer wall of the driving rotating rod 4 is fixedly installed with a fixed rod 8. The fixed rod 8 is L-shaped. The upper side wall surface of the vertical end of the fixed rod 8 is rotatably installed with a sliding roller 9. The top wall surface inside the cavity of the connecting cylinder 6 is fixedly installed with a contact block 10.
