Description

Technical Field

[0001] This utility model relates to the field of automatic sheet-shaping technology for rubber mixing machines, and more particularly to an automatic sheet-shaping device for rubber mixing machines. Background Technology

[0002] The rubber mixing mill is considered the core equipment in the rubber processing industry, playing an irreplaceable and crucial role in the entire rubber product manufacturing process. Its main structure consists of two opposing rotating rollers, which are the main working components for the mixing operation. During operation, raw rubber and various compounding agents are fed between these two rollers. The rotation of the rollers generates strong mechanical force, while simultaneously controlling the temperature of the equipment, allowing the raw rubber and compounding agents to fully blend and disperse evenly under the combined action of high temperature and mechanical force. This mixed rubber lays the foundation for subsequent manufacturing of tires, rubber hoses, rubber seals, and other rubber products, and is a key step in determining the final quality and performance of rubber products.

[0003] Existing film production equipment mainly consists of basic conveying devices and simple stacking platforms. The film is conveyed to the stacking platform via a conveyor system, which uses a motor to drive rollers to move the film. The stacking platform is simply a flat surface used to support the film.

[0004] During the production of rubber sheets, static electricity is generated by friction between the rubber sheets and the equipment, causing the sheets to stick together and be stacked haphazardly. This not only delays the production schedule but also affects product quality. Furthermore, when encountering rubber sheets of different specifications, the stacking method can only be adjusted manually, which is inefficient and difficult to adjust precisely, resulting in uneven stacking, causing trouble for subsequent production and affecting product quality. Therefore, an automatic sheet-laying device for rubber mixing mills is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic sheet-laying device for rubber mixing machines, which aims to improve the problems of rubber sheet adhesion, messy stacking, and low efficiency and unevenness caused by manual stacking of rubber sheets of different specifications in existing rubber sheet production equipment.

Two swing rollers are rotatably connected at equal intervals between the inner sides of the two mounting frames. A trolley is provided between the columns, and the trolley is connected to a corresponding locking assembly.

[0007] As a further description of the above technical solution: an anti-static component is also provided on the outside of the column to remove static electricity generated during operation;

[0008] As a further description of the above technical solution: the static elimination component includes a static column, which is disposed on the outside of the column. The receiving end of the static column is connected to one end of a spring static tube, and the other end of the spring static tube is connected to a placement plate.

[0009] As a further description of the above technical solution: the locking assembly includes a U-shaped plate, each U-shaped plate is disposed on the outer side of the corresponding column, each U-shaped plate has a sliding locking rod inside, each locking rod has a fixing ring on the outer side of the locking ring, each fixing ring has a spring between the fixing ring and the inner side of the U-shaped plate, and each fixing ring has a pull rod on the outer side.

[0013] As a further description of the above technical solution: the electric telescopic rod can automatically adjust the telescopic stroke according to the different lengths of the rubber sheet, so as to adapt to the stacking of rubber sheets of different specifications;

[0014] As a further description of the above technical solution: the electric slider works in conjunction with the slide rail to enable the placement plate to move horizontally at an appropriate speed, thereby ensuring that the rubber sheets are placed evenly and neatly.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, an antistatic assembly composed of an electrostatic column and a spring electrostatic tube is used to effectively eliminate static electricity on the film surface.

[0025] Reference Figures 1-2This utility model provides an embodiment of an automatic sheet-laying device for a rubber mixing mill, including columns 1, which support the frame structure of the entire device, ensuring the stability and load-bearing capacity of each component. The columns 1 are connected by connecting rods 6, linking adjacent columns 1 to enhance the overall integrity and stability of the structure. Two slide rails 7 are symmetrically distributed at the top of the four columns 1, providing guidance for the sliding of electric sliders 8 and ensuring the accuracy of their horizontal movement. Electric sliders 8 slide along the outside of each slide rail 7, driving the fixed plate 12 to move horizontally, thus achieving the horizontal movement of the placement plate 13. For positioning, a fixed plate 12 is provided between the two electric sliders 8. The fixed plate 12 connects the electric sliders 8 and the electric telescopic rod 9 to transmit power and ensure the positioning of the placement plate 13. The electric telescopic rod 9 is provided in the middle of the fixed plate 12. The electric telescopic rod 9 can automatically adjust its extension stroke according to the different lengths of the rubber sheets to accommodate the stacking of rubber sheets of different specifications. Limiting rods 10 are slidably provided on the fixed plate 12 and on both sides of the electric telescopic rod 9. The limiting rods 10 are connected to the electric telescopic rod 9 to limit the vertical movement range of the placement plate 13 and prevent it from exceeding the predetermined position. Limiting plates 11 are provided at the top of each limiting rod 10. A placement plate 13 is provided between the output end of the telescopic rod 9 and the bottom end of the limiting rod 10 to support rubber sheets and move vertically to stack the sheets. A slide rail 14 is provided on the outer side of the placement plate 13 to guide the sliding of sliders 15. Two sliders 15 slide equidistantly on the outer side of the slide rail 14, driving the limiting roller 16 to move horizontally and adjust the placement position of the rubber sheets. Limiting rollers 16 are rotatably connected to the outer side of each slider 15 to adjust the placement position of the rubber sheets and ensure neat stacking. Mounting brackets 17 are provided at both ends of the placement plate 13. Two swing rollers 18 are equidistantly rotatably connected to the inner sides of the frame 17. The two ends of the placement plate 13 are fixed to the inner side of the mounting frame 17 to support the rotation of the swing rollers 18. An antistatic assembly is also provided on the outer side of the column 1. The antistatic assembly includes an antistatic column 2, which is located on the outer side of the column 1. The receiving end of the antistatic column 2 is connected to one end of the spring antistatic tube 3, and the other end of the spring antistatic tube 3 is connected to the placement plate 13 to eliminate static electricity on the surface of the film and prevent the film from sticking together. A trolley 4 is provided between the columns 1, and the trolley 4 is connected to the corresponding locking assembly to carry the stacked film for easy transportation and handling.

[0026] Guide plates 21 are provided between the columns 1 on both sides of the placement plate 13. Guide plates 20 are provided on the top of the guide plates 21. The guide plates 20 and 21 are for the purpose of placing the trolley 4 better inside the column 1.

[0027] The electric slider 8 works in conjunction with the slide rail 7 to allow the placement plate 13 to move horizontally at an appropriate speed, ensuring that the rubber sheets are placed evenly and neatly.

[0028] Reference Figures 3-4 The locking assembly includes a U-shaped plate 22, which is set on the outer side of the corresponding column 1. A locking rod 25 slides inside the U-shaped plate 22. A fixing ring 23 is set on the outer side of the locking rod 25. A spring 26 is set between the fixing ring 23 and the inner side of the U-shaped plate 22. The spring 26 provides the power for the pull rod 24 to return. A pull rod 24 is set on the outer side of the fixing ring 23. The pull rod 24 is used to facilitate the unlocking by the staff and to fix the cart 4 to prevent it from shifting during transportation.

[0029] Each of the two outer corners of the flatbed cart 4 is provided with a locking block 27, and the locking rod 25 can engage with the round hole of the corresponding locking block 27. The locking block 27 is located at the two outer corners of the flatbed cart 4 and engages with the locking rod 25 to fix the flatbed cart 4.

[0030] The two sides of the flatbed cart 4 are respectively provided with single-piece hanging ears 5 and U-shaped hanging ears 19. When two flatbed carts 4 are connected, the adjacent single-piece hanging ears 5 and U-shaped hanging ears 19 on the two flatbed carts can be engaged. The single-piece hanging ears 5 and U-shaped hanging ears 19 are engaged by pins. The single-piece hanging ears 5 and U-shaped hanging ears 19 are set on both sides of the flatbed cart 4 and connected by pins, which facilitates the movement and disassembly of the flatbed cart 4. The pins are used to connect the single-piece hanging ears 5 and U-shaped hanging ears 19 to realize the disassembly and connection of the flatbed cart 4.

[0031] Working principle: First, the equipment moves horizontally on the slide rail 7 via the electric slider 8 to adjust the overall working position of the equipment. When the electric slider 8 slides to the appropriate position, the electric telescopic rod 9 starts to work to drive the placement plate 13 to move vertically to accommodate rubber sheets of different sizes. The placement plate 13 places the rubber sheet in the appropriate position inside the trolley 4 through the telescopic function of the electric telescopic rod 9.

[0032] After the film comes out of the rubber mixing mill production line, the workers place the film between the oscillating rollers 18 and guide it through the limiting rollers 16. The oscillating rollers 18 rotate in cooperation with the placement plate 13 to ensure the film is placed stably. At the same time, the electric telescopic rod 9 adjusts the vertical position of the placement plate 13 so that the film is stacked layer by layer with an appropriate spacing between each layer. During the placement process, the film is guided by the limiting rollers 16 and the oscillating rollers 18 to prevent misalignment or overlap between the film.

[0033] During the stacking of the rubber sheets, the trolley 4 is connected to the locking assembly, U-shaped plate 22, locking rod 25 and locking block 27 to ensure stability. The locking rod 25 engages with the round hole of the locking block 27 to lock the trolley 4 and prevent any unnecessary displacement or shaking during the stacking process. In this way, the trolley 4 provides a stable carrier and ensures the accurate stacking of the rubber sheets.

[0034] During the stacking of film, the placement plate 13 will gradually move upward in the vertical direction. Each time a layer of film is placed, the placement plate 13 can be raised accordingly to eventually form a neat stacking structure. During this process, the electrostatic column 2 eliminates the static electricity on the surface of the film through the spring electrostatic tube 3 to prevent the film from sticking together and ensure the separation of the film during the stacking process.

[0035] Once stacking is complete, the trolley 4, through the single-piece hanging lug 5 connected to the pin and the U-shaped hanging lug 19, moves the stacked film out of the stacking area, ready to enter the next process. At this time, the placement plate 13 will return to its original position, and the electric slider 8 will continue to slide, readjusting the device to the working position of the next film to be stacked, and starting a new stacking process.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
