Description

Technical Field

[0001] The invention relates to the technical field of rubber mixing equipment, in particular to rubber mixing equipment for producing steel wire core conveyor belts. Background Art

[0002] Steel wire conveyor belt is a high-performance industrial conveyor belt, which uses high-strength steel wire rope as the load-bearing skeleton and is covered with rubber or other wear-resistant materials. Compared with traditional fabric core conveyor belts, steel wire conveyor belts have higher tensile strength, lower elongation, better troughability and stronger impact resistance. They are suitable for long-distance, large-volume, high-speed material transportation occasions and are widely used in mining, ports, electric power, metallurgy, chemical industry and other industries.

[0003] The first step in the production of steel wire conveyor belts is to use an internal mixer to mix the rubber. Rubber mixing refers to the process of mixing and plasticizing raw rubber with various compounding agents (such as vulcanizers, accelerators, fillers, softeners, antioxidants, etc.) in a closed mixer according to a certain formula and sequence. This process is crucial to the quality of rubber products because it directly affects the physical and mechanical properties, processing performance and appearance of the final product.

[0004] The current rubber mixing process has the following defects:

[0005] 1. In order to avoid bumps and abrasions during transportation of rubber raw material blocks, a protective film will be wrapped around the outer wall of the rubber raw material blocks. Before loading, the protective film needs to be torn off manually, which is time-consuming and laborious, and increases the workload;

[0006] 2. The rubber after mixing is mostly unloaded by a bucket. In this way, the rubber after mixing is fully exposed, and the odorous gas is released in the workshop, polluting the processing environment. The mixed rubber is easy to adhere to the bucket and needs to be taken out manually. Summary of the invention

[0041] 6. The partition component is set to extend out to block the temporary storage chamber. One batch of materials is kneaded in the stirring and molding component, and another batch of materials is cut and temporarily stored in the block stripping component. In this way, when the kneading is completed, the sealed rubber is output and the temporarily stored materials are input, so as to realize rapid material replenishment and effectively reduce the waiting time; when the kneading is completed and opened, the stirring and molding component can absorb the odorous gas under negative pressure, and the odorous gas is discharged after being processed, which is more environmentally friendly, reduces the impact on the working environment, and improves the working environment of workers;

[0042] 7. When unloading, the bottom sealing component is moved vertically to open, so as to realize vertical unloading, and the stirring and forming component can be moved horizontally to push out, so as to fully clean the stirring and forming component. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, a winding wheel is provided on one side of the triangle plate. The second negative pressure hole of the winding wheel can pre-absorb and position the protective film. As the winding wheel rotates, the peeled protective film is rolled up and stored. At the same time, the main peeling force in the subsequent peeling operation comes from the winding traction of the winding wheel.

[0093] S3, when the film opening assembly 8 moves outward to the outermost end, the film opening assembly 8 peels off the protective film 91b on the bottom and side surfaces of the rubber raw material block 9b, and at the same time, the rubber raw material block 9b falls to the top surface of the grid frame 9c;

[0094] S4, the pressing plate 42 presses down the rubber raw material block 9b, and the rubber raw material block 9b is cut and falls into the temporary storage chamber;

[0095] S5, the pressing plate 42 is reset upward to above the side discharge hole, the winding wheel 842 is reversed to release the protective film 91b, and the first negative pressure hole 421 adsorbs the protective film 91b and moves upward;

[0096] S6, the swing plate 43 reciprocates and flips to hit the protective film 91b, so that the residual material blocks on the protective film 91b fall off;

[0097] S7, the swing plate 43 remains in a horizontal state, and the negative pressure fan 521 in the waste storage box 52 starts to work, so that the protective film 91b is discharged from the side discharge port 512.

A seventh driving rod 63 is installed on the back of the stirring frame 61. A stirring wheel 64 is symmetrically installed inside the stirring frame 61. The end of the stirring wheel 64 is connected to the second motor 66. The second motor 66 is fixed on the surface of the slide plate 65. The slide plate 65 is slidably installed on the top of the transverse guide rail 67.

The outer end of the bottom sealing plate 71 is slidably installed on the surface of the storage seat 72, and the output end of the fifth driving rod 73 is connected to the bottom sealing plate 71.

[0102] In the above scheme:

[0103] When unloading, the fifth driving rod drives the bottom sealing plate to move longitudinally and open, so that the sealing rubber falls out and is discharged. While unloading, the stirring wheel rotates to improve the unloading efficiency;

[0104] The operator observes the residual condition of the stirring frame through the observation window. If the residual condition is too much, the seventh driving rod drives the stirring frame to move horizontally. In this way, the stirring frame is fully exposed, and the operator can fully clean the stirring frame from the outside to ensure the mixing effect.
