Description

Technical Field

[0001] The invention belongs to the technical field of material processing, in particular to a preparation device and process for a high-friction conveyor belt material. Background Art

[0002] High friction conveyor belts are often used in conveying applications that require greater grip and traction, especially when it is necessary to prevent material from sliding or to ensure stable contact between the conveyor belt and the material. Such conveyor belts usually use special surface materials and structures to increase the coefficient of friction. The surface of high friction conveyor belts is usually made of rubber, polyurethane or other high friction materials with a high coefficient of friction. The closed mixer is referred to as an internal mixer. It is mainly used for plasticating and mixing rubber. The internal mixer is a machine with a pair of rotors of a specific shape that rotate relative to each other. It intermittently plasticates and mixes polymer materials under a closed state with adjustable temperature and pressure. It is mainly composed of a mixing chamber, a rotor, a rotor sealing device, a feeding and pressing device, a discharging device, a transmission device and a machine base.

[0003] A patent application CN114474461B discloses a closed mixer with adjustable ratio. The key points of its technical solution are: it includes a base, the top of the base is fixedly connected to the internal mixer body, the internal mixer body is provided with a mixing bin, the top of the base is fixedly connected to an equipment box located on one side of the internal mixer body, the top of the equipment box is rotatably connected to a top plate, the bottom of the top plate is fixedly connected to a feed bin matched with the mixing bin, this closed mixer with adjustable ratio is provided with a weighing plate, and a pressure sensor is provided in the weighing plate. Therefore, when the pressure sensor detects that the material reaches the set pressure value, the weighing plate is driven to move by the set moving component, so that the feed bin is connected to the mixing bin, so that the material enters the mixing bin, thereby solving the problem in the prior art that the internal mixer body cannot control the proportion of each group of materials.

[0004] However, the above technology often has the following defects: the above device needs to completely retract the extrusion plate into the groove when loading separately, and then rotate the top plate and the cylinder together through the driving structure to open the top of the feed bin. The operation is relatively cumbersome and the loading takes a long time. The raw material composition of the high-friction conveyor belt is more complex, including rubber, friction enhancer (such as filler, metal particles, carbon black, quartz sand, silica sand and other additives, etc.). The loading process is more complicated than the loading process of the traditional device. The cumbersome loading operation of the above device will further reduce the loading and preparation efficiency of the high-friction conveyor belt material. To this end, the present invention provides a preparation device and process for high-friction conveyor belt materials. Summary of the invention

[0024] S6. After the mixing is completed, the hydraulic cylinder drives the telescopic rod, the fixed plate and the movable plate to move to a position relative to the feed port, and the drive motor drives the mixer body to rotate and open, pouring out the mixed material, and at the same time, the raw material is added again through the feed port to achieve continuous operation.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. The present invention discloses a device and process for preparing high-friction conveyor belt materials. By setting an extrusion assembly and a driving assembly, the raw materials are put into the feed port. At this time, the movable plate is supported by a torsion spring so that the movable plate maintains a water level state to carry the raw materials. The hydraulic cylinder drives the telescopic rod, the fixed plate, the movable plate and the raw materials to move downward together. When the gear and the teeth are in contact and meshing, the movable plate is driven to flip downward to pour the raw materials into the mixing chamber of the internal mixer body. When the gear completely passes the teeth, the movable plate is reset to a horizontal position by the torsion spring, and the hydraulic cylinder continues to drive the telescopic rod, the fixed plate, the movable plate and the raw materials to move downward together. The plate and the movable plate move down to squeeze the raw materials below and assist the internal mixer body to mix the raw materials; after mixing is completed, the hydraulic cylinder drives the telescopic rod, the fixed plate and the movable plate to move up to a position relative to the feed port, and the internal mixer body is driven by the driving motor to rotate and open, and the mixed material is poured out, and the raw materials are put into the feed port again to achieve continuous operation. In this way, the raw materials needed for the next mixing can be placed on the top plate of the movable plate while the material is discharged. When the internal mixer body is aligned with the feed bin again, mixing can be carried out again, which shortens the waiting time for loading and improves the processing efficiency.

[0027] 2. The device and process for preparing a high-friction conveyor belt material described in the present invention are provided with an elastic rod and a sphere; when the gear completely passes through the teeth, the movable plate is reset to a horizontal position by a torsion spring. During the resetting process of the movable plate, the elastic rod, the sphere and the movable plate move asynchronously due to inertia and move relative to each other. The elastic rod is deformed so that the sphere repeatedly hits the inner wall of the cavity. The vibration generated by the impact shakes off the residual raw material attached to the surface of the movable plate, thereby preventing the raw material from adhering to the surface of the movable plate and causing waste of raw material.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] Embodiment 1: Figures 1 to 6 As shown, a device for preparing a high friction conveyor belt material according to an embodiment of the present invention comprises:

[0039] A base 1, on which a mixer body 2 and an equipment box are fixedly mounted, a top plate 3 is fixed on the top of the equipment box, a feed bin 4 is fixed on the lower end surface of the top plate 3, a feed port 5 is provided on the side wall of the feed bin 4, and the feed bin 4 is adapted to the mixer body 2;

[0040] An extrusion assembly, through which the material inside the internal mixer body 2 is extruded, the extrusion assembly includes a pressing plate 9, the pressing plate 9 is composed of a fixed plate 10 and a movable plate 11, the movable plate 11 is provided with two and is rotatably mounted on both sides of the fixed plate 10 through a connecting shaft 12, a torsion spring 13 is fixed on the connecting shaft 12 to reset the movable plate 11, a hydraulic cylinder 6 is fixed above the top plate 3, a telescopic rod 7 is movably mounted on the output end of the hydraulic cylinder 6, the telescopic rod 7 extends downward to the inside of the feed bin 4 and the bottom end is fixedly connected to the fixed plate 10;

[0041] A driving assembly, through which the movable plates 11 on both sides are driven to flip downward, so as to add materials into the internal mixer body 2;

[0042] When working, first select the raw materials for making high-friction conveyor belts, the raw materials include rubber, friction enhancers (such as fillers, metal particles, carbon black, quartz sand, silica sand, etc.) and other additives; weigh various raw materials according to preset proportions, and then put various raw materials into the feed port 5 according to corresponding proportions. At this time, the movable plate 11 is supported by the torsion spring 13, so that the movable plate 11 maintains the water level state to carry the raw materials, and then the movable plates 11 on both sides are driven to flip downward by the driving component, and the raw materials are put into the internal mixer body 2 for mixing; after the raw materials are added, the movable plate 11 is reset by the torsion spring 13, and then the telescopic rod 7, the fixed plate 10 and the movable plate 11 are continued to be driven downward by the hydraulic cylinder 6 to squeeze the raw materials below, thereby assisting the internal mixer body to The raw materials are mixed, and the raw materials in the mixing chamber and the mixing rollers are pressed together by downward pressure, so that the density of the raw materials inside the mixer can be maintained, ensuring that the various components are fully in contact and evenly mixed, and appropriate pressure helps to improve the mixing efficiency; after the mixing is completed, the hydraulic cylinder 6 drives the telescopic rod 7, the fixed plate 10 and the movable plate 11 to move up to a position relative to the feed port 5, and the mixer body is driven by the driving motor to rotate and open, and the mixed materials are poured out, and the raw materials are added again through the feed port 5 to achieve continuous operation, so that the raw materials required for the next mixing can be placed on the top plate 3 of the movable plate 11 while the materials are discharged, and when the mixer body is aligned with the feed bin 4 again, mixing can be carried out again, which shortens the waiting time for loading and improves the processing efficiency.

[0043] The driving assembly includes a gear 15, which is fixedly installed in an opening 1 in the middle of the side of the movable plate 11 close to the fixed plate 10. The fixed plate 10 has an opening 2 opposite to the opening 1 on the side, and a vertical rod 14 is arranged in the opening 2. The top of the vertical rod 14 is fixedly connected to the top plate 3, and a plurality of teeth 18 are fixed to the lower side wall of the vertical rod 14, and the teeth 18 are adapted to the gear 15. When working, the telescopic rod 7 is driven downward by the hydraulic cylinder 6, thereby driving the fixed plate 10 and the movable plate 11 to move downward. The gear 15 moves downward together with the raw materials. When the gear 15 and the teeth 18 are in contact and meshing, the movable plate 11 can be driven to flip downward to pour the raw materials into the mixing chamber of the internal mixer body 2. The number of teeth 18 is limited, and the angle of driving the movable plate 11 to rotate is less than 90 degrees. When the gear 15 completely passes through the teeth 18, the movable plate 11 is reset to a horizontal position through the torsion spring 13, so that the fixed plate 10 and the movable plate 11 can be combined to form a pressing plate 9 to squeeze the raw materials below, thereby assisting the internal mixer body to mix the raw materials.

[0044] A sealing plate 8 is fixed on the telescopic rod 7 and above the pressure plate 9, a vertical plate 16 is fixed on the lower end surface of the sealing plate 8, a vertical plate 2 17 is fixed on the top of the movable plate 11, and an electromagnetic block 22 is fixed on the side wall of the vertical plate 16, and the electromagnetic block 22 can adsorb the vertical plate 2 17 after being energized; when working, the movable plate 11 is in a horizontal state through the torsion spring 13, and the electromagnetic block 22 is energized at this time, and the electromagnetic block 22 generates a magnetic force to stably adsorb the vertical plate, so that the movable plate 11 is stably maintained at the water level position, so that the raw material can be stably supported, and when the movable plate 11 drives the raw material to move down to a position adjacent to the teeth 18, the electromagnetic block 22 is powered off and the suction force disappears, so that it is convenient to drive the movable plate 11 to flip downward and open through the cooperation of the teeth 18 and the gear 15, and then the raw material is quickly put into the internal mixer body 2.

[0045] The sides of the sealing plate 8, the vertical plate 1 16, the vertical plate 2 17, the fixed plate 10, the movable plate 11 and the electromagnetic block 22 are all in contact with the inner walls of the feed bin 4 and the mixing bin of the internal mixer body 2, and the vertical rod 14 seals and slides through the through hole provided on the sealing plate 8; during operation, the raw materials need to be heated while being mixed, and the adjacent positions of the above structures are closely fitted to reduce heat dissipation, so as to save resources, and at the same time, the raw materials are kept at a suitable processing temperature to ensure the processing efficiency of the raw materials.

[0046] An elastic member 21 is fixed to the side of the movable plate 11 away from the fixed plate 10, and an elastic block 19 is fixed to the upper side wall of the vertical plate 2 17. The elastic block 19 and the elastic member 21 are both hollow structures, and air is stored inside the elastic block 19. The elastic block 19 and the elastic member 21 are connected through the airway 20. During operation, when the electromagnetic block 22 and the vertical plate 2 17 are adsorbed together, the vertical plate 1 16 and the vertical plate 2 17 simultaneously squeeze the elastic block 19, and press the air inside the elastic block 19 into the elastic member 21 along the airway 20, so that the elastic member 21 expands outward, so that the elastic member 21 fits with the inner walls of the mixing bin of the feed bin 4 and the internal mixer body 2, so as to block the gap between the end of the movable plate 11 and the inner walls of the mixing bin of the feed bin 4 and the internal mixer body 2, and further prevent heat loss.

[0047] When the lower end surface of the pressing plate 9 contacts the material inside the internal mixer body 2, the sealing plate 8 moves to below the feed port 5; during operation, the side edges of the sealing plate 8 fit against the inner walls of the feed bin 4 and the mixing bin of the internal mixer body 2, and by positioning the sealing plate 8 below the feed port 5, heat is further prevented from being lost from the feed port 5.

[0048] When the vertical plate 17 is in contact with the electromagnetic block 22, the lower end surfaces of the fixed plate 10 and the movable plate 11 are flush; during operation, the lower end surface of the pressing plate 9 formed by the fixed plate 10 and the movable plate 11 is flat, so that the top of the raw material is evenly stressed, so that the raw material and the mixing roller are pressed together.

[0049] A cavity 23 is provided inside the movable plate 11, an elastic rod 24 is fixed in the middle of the cavity 23, and a sphere 25 is fixed at the end of the elastic rod 24; during operation, when the gear 15 completely passes through the tooth 18, the movable plate 11 is reset to a horizontal position through the torsion spring 13. During the resetting process of the movable plate 11, the elastic rod 24, the sphere 25 and the movable plate 11 move asynchronously due to inertia, and move relative to each other. The elastic rod 24 is deformed, so that the sphere 25 repeatedly hits the inner wall of the cavity 23. The vibration generated by the impact shakes off the residual raw materials attached to the surface of the movable plate 11, thereby preventing the raw materials from being attached to the surface of the movable plate 11 and causing a waste of raw materials.

[0050] Embodiment 2: Figure 5 and Figure 6 As shown, compared with Example 1, another implementation of the present invention is that the sphere 25 is an elastic ball; when working, the sphere 25 can collide with the inner wall of the cavity 23 multiple times to enhance the shaking effect, which is conducive to shaking off the residual raw materials.

[0055] S4, the hydraulic cylinder 6 drives the telescopic rod 7 to move downward, thereby driving the fixed plate 10, the movable plate 11 and the raw material to move downward together. When the gear 15 and the teeth 18 are in contact and meshing, the movable plate 11 is driven to flip downward, and the raw material is poured into the mixing chamber of the internal mixer body 2;

[0056] S5. When the gear 15 completely passes through the teeth 18, the movable plate 11 is reset to the horizontal position through the torsion spring 13, and the hydraulic cylinder 6 continues to drive the telescopic rod 7, the fixed plate 10 and the movable plate 11 to move downward, squeezing the raw materials below and assisting the internal mixer body to mix the raw materials;

[0057] S6. After the mixing is completed, the hydraulic cylinder 6 drives the telescopic rod 7, the fixed plate 10 and the movable plate 11 to move up to a position relative to the feed port 5, and the drive motor drives the mixer body to rotate and open, pouring out the mixed material, and at the same time, the raw material is added again through the feed port 5 to achieve continuous operation.

[0058] Working principle: First, select the raw materials for making the high-friction conveyor belt; weigh the various raw materials according to the preset ratio, and then put the various raw materials into the feed port 5 according to the corresponding ratio. At this time, the movable plate 11 is supported by the torsion spring 13, so that the movable plate 11 maintains the water level state to carry the raw materials; the hydraulic cylinder 6 drives the telescopic rod 7 to move downward, and then drives the fixed plate 10, the movable plate 11 and the raw materials to move downward together. When the gear 15 and the teeth 18 are in contact and meshing, the movable plate 11 is driven to flip downward, and the raw materials are poured into the mixing In the refining chamber; when the gear 15 completely passes through the teeth 18, the movable plate 11 is reset to the horizontal position through the torsion spring 13, and the hydraulic cylinder 6 continues to drive the telescopic rod 7, the fixed plate 10 and the movable plate 11 to move downward, squeezing the raw materials below, and assisting the internal mixer body to mix the raw materials; after mixing, the hydraulic cylinder 6 drives the telescopic rod 7, the fixed plate 10 and the movable plate 11 to move up to a position relative to the feed port 5, and drives the internal mixer body to rotate and open through the drive motor to pour out the mixed material, and at the same time, the raw materials are put in again through the feed port 5 to achieve continuous operation.
