Description

Technical Field

[0001] The invention relates to the technical field of screw extruders, in particular to an adjustable twin-screw extruder for processing rubber products and a use method thereof. Background Art

[0002] Screw extruder, also known as extruder, is one of the main equipment for rubber processing. It has been used in the rubber industry for more than 100 years. With the continuous emergence of new materials, new processes and new technologies in the rubber industry, screw extruders have also been continuously developed and improved. There are various types and specifications of extruders to meet the processing needs of different rubber products. Twin-screw extruders are divided into two categories: one is a vertical twin-screw extruder, in which the two screws are arranged vertically, one is responsible for precise feeding, and the other is responsible for efficient feeding. The two work together to ensure the smoothness and uniformity of the material during the extrusion process; the other is a parallel twin-screw extruder, in which the two screws are arranged in parallel and jointly bear the heavy task of feeding. Through precise screw design and coordination, deep mixing and efficient plasticization of rubber materials are achieved, thereby improving the quality and production efficiency of the products.

[0003] At present, there are some problems that need to be improved in the extruders with two screws arranged in a vertical layout. The discharge angle cannot be adjusted and there is a lack of necessary adjustment mechanism. This directly leads to the fact that in certain specific processing scenarios, the feeding speed appears to be relatively slow and it is difficult to flexibly adjust according to production needs, which limits the improvement of production efficiency to a certain extent. In addition, the flow of materials in the pipeline may encounter resistance, affecting the continuity and smoothness of the feed, which poses a potential threat to ensuring the quality consistency of rubber products. At the same time, the efficiency of the pipeline heating system needs to be improved, and the plasticization effect of rubber materials is not good enough. Summary of the invention

[0017] S2. According to processing requirements, the height of the top plate is adjusted through the adjustment mechanism to facilitate the flow of materials out of the second tube body;

[0018] S3, adjusting the position of the electric heater on the first tube body and the position of the vibration motor on the second tube body through the driving mechanism, starting the electric heater to heat the material in the first tube body to reach a suitable extrusion temperature, and at the same time, starting the vibration motor to vibrate the second tube body to promote the flow of the material in the tube body to prevent blockage;

[0019] S4. After the material is fully mixed and heated in the second tube body, the material is pushed out from the outlet of the second tube body by the second pushing screw to form the desired rubber product.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] Firstly, in the present invention, two power components are installed on the base, and the power components are used to drive the second block to move. The second block pushes the hinge rod to rotate the hinge rod on the first block, so that the first block drives the top plate to rotate. The hinge plate connected to the top plate rotates in the fixed block, and the inclination angle of the top plate can be adjusted. Therefore, the discharge point of the second tube body is tilted, and the material discharge speed is increased under the action of gravity. It can be flexibly adjusted according to production needs, making the production process smoother and greatly improving the overall production efficiency.

After the fourth motor drives the second screw to rotate, the second screw block drives the first moving ring to move, and the third screw is driven to rotate through the transmission assembly, so that the third screw block drives the second moving ring to move. During this process, the electric heater moves back and forth with the first moving ring on the outside of the first tube body to perform reciprocating heating, which not only ensures that the material reaches the ideal temperature state when entering the processing area, but also greatly improves the heating efficiency and uniformity. At the same time, the vibration motor vibrates the second tube body as the second moving ring moves back and forth, effectively preventing the blockage and accumulation of materials at the outlet, improving the smoothness and continuity of the feeding, and thus facilitating the processing of rubber products.

[0042] S4. After the material is fully mixed and heated in the second tube body 33, the material is pushed by the second pushing screw 34 to be extruded from the outlet of the second tube body 33 to form the desired rubber product.

[0043] The working principle of the present invention is: when it is necessary to adjust the inclination of the first tube body 31, the third motor 541 is used to drive the second shaft rod 543 to rotate, the second shaft rod 543 drives the worm 544 to rotate, the worm 544 drives the worm wheel 545 to rotate, and the two worm wheels 545 drive the first screw rod 546 to rotate, thereby driving the first screw block 547 to slide in the first slide groove 55, and the movement is more stable under the action of the first limit rod 56, so that the first screw block 547 drives the second matching block 533 to move, and the hinge rod 532 rotates between the first matching block 531 and the second matching block 533, so that the hinge plate 52 can be rotated at the fixed block 51, so as to adjust the inclination angle of the first tube body 31 above the top plate 2, improve the material discharging speed, and can be flexibly adjusted according to production needs, so that the production process is smoother, and the fourth motor 81 drives the second matching block 533 to move.
