Description

Technical Field

[0001] This utility model relates to the field of rubber mixing machine technology, and in particular to an automatic turning device for an open rubber mixing machine. Background Technology

[0002] Open mixing mills are key pieces of equipment in the rubber industry used for rubber compounding, plasticizing, and sheeting. During the mixing process, the rubber compound is crushed and sheared on rollers, requiring periodic turning to promote uniform mixing. Traditional turning operations rely entirely on manual labor, with workers using hand tools such as shovels or hooks. This method is labor-intensive, inefficient, and poses safety hazards, such as the risk of workers' hands being pinched by the rollers. Furthermore, manual turning results in poor consistency, is influenced by the operator's experience, and is prone to fluctuations in rubber compound quality. Although some automated turning devices have been proposed, they are often complex in structure, expensive, and inconvenient to change turning tools, making them difficult to adapt to different rubber compounds and process requirements.

However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0016] like Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides an automatic turning device for an open-type rubber mixing mill, including: a support mechanism 1, which includes a horizontally arranged base 2 and two vertically arranged support plates 3 on the base 2, the two support plates 3 being located on opposite axial sides of the rollers of the open-type rubber mixing mill; a transverse moving mechanism 4, which includes two horizontal linear guides 5 arranged on the upper part of the support plates 3, a servo motor 6 mounted on the support plates 3, the output shaft of the servo motor 6 driving the sliders of the two horizontal linear guides 5 to move synchronously through a synchronous belt transmission assembly 7, the synchronous belt transmission assembly 7 including a driving pulley, a driven pulley and a synchronous belt, the output shaft of the servo motor 6 driving the driving pulley to rotate through the synchronous belt driving the driven pulley to rotate, the driving pulley and the driven pulley driving the ball screws of the two horizontal linear guides 5 to rotate, thereby making the sliders of the horizontal linear guides 5 move horizontally and linearly, ensuring the synchronicity of the slider movement on the two horizontal linear guides 5 and precise positioning control; vertical lifting The vertical lifting mechanism 8 includes a connecting plate 23 mounted on two sliders of two horizontal linear guide rails 5. A vertically downward cylinder 9 is mounted in the middle of the connecting plate 23, and a mounting plate 10 is connected to the piston rod of the cylinder 9. The glue-turning execution mechanism 11 includes a U-shaped fixing plate 24 located in the middle of the mounting plate 10. A vertically downward transmission shaft 12 is located at the bottom of the fixing plate 24. A drive motor 13 for driving the transmission shaft 12 to rotate is installed inside the fixing plate 24. A glue-turning tool head 15 is detachably connected to the transmission shaft 12 through a magnetic connector 14. Through the coordinated action of the support mechanism 1, the lateral movement mechanism 4, the vertical lifting mechanism 8, and the glue-turning execution mechanism 11, the support mechanism 1 provides a stable foundation, the lateral movement mechanism 4 achieves axial coverage, the vertical lifting mechanism 8 adjusts the height, and the glue-turning execution mechanism 11 performs the turning action, realizing automated turning, replacing manual operation, and improving production efficiency and safety.

[0017] The horizontal linear guide 5 is parallel to the axis of the rolling mill roller. The length of the horizontal linear guide 5 is 200-300mm longer than the working length of the rolling mill roller. The extended design of the horizontal linear guide 5 allows the rubber turning tool head 15 to move beyond both ends of the roller, ensuring full coverage of the working area and eliminating turning dead angles by expanding the range of movement.

[0018] The slider of the horizontal linear guide rail 5 is provided with guide posts 16 located on both sides of the cylinder 9. The mounting plate 10 is provided with guide holes for the guide posts 16 to pass through. The bottom end of the guide post 16 is provided with a limit block 25. The guide post 16 guides the lifting movement, and the limit block 25 sets the lower limit. The lifting accuracy and safety are improved by guiding the guide post 16.

[0019] The magnetic connector 14 includes a permanent magnet base 17 fixed to the bottom end of the drive shaft 12 and a magnetic guide base 18 fixed to the glue-turning tool head 15. The permanent magnet base 17 is embedded with a ring of neodymium iron boron permanent magnets 19. Magnetic attraction is used to achieve quick connection of the glue-turning tool head 15. The neodymium iron boron permanent magnets 19 generate a strong magnetic force, attracting the magnetic guide base 18 to complete the fixation. The magnetic attraction between the permanent magnet base 17 and the magnetic guide base 18 is designed to be much greater than the maximum axial resistance of the glue-turning tool head 15 during operation, ensuring a safe and reliable connection.

[0020] The bottom surface of the permanent magnet base 17 is provided with a positioning boss 20, and the magnetic guide base 18 is embedded with a magnetic guide sheet 21 made of soft magnetic material. The top surface of the magnetic guide sheet 21 is provided with a positioning groove 22 that cooperates with the positioning boss 20. The positioning boss 20 and the positioning groove 22 cooperate to achieve rapid positioning and prevent the glue-turning tool head 15 from shifting when rotating.

[0021] The positioning boss 20 is designed in the shape of a pyramid, and the positioning groove 22 is designed in the shape of a pyramid with matching pyramid shape. The facets of the pyramid cooperate to form a mechanical interlock, which can directly transmit the large torque generated by the drive motor 13. This avoids the circumferential slippage or rotation of the turning tool head 15 relative to the transmission shaft 12 during operation, ensuring the accuracy and stability of the turning action and realizing reliable circumferential positioning and torque transmission. At the same time, the axial adsorption force provided by the magnetic connector 14 works together with the mechanical interlock structure to ensure the integrity and reliability of the connection under high torque conditions.

[0022] The rubber turning tool head 15 includes a spike-tooth rubber turning head, a paddle-type rubber turning head, and a scraper-type rubber turning head. The various rubber turning tool heads 15 are adapted to different processes. The type of tool head is selected according to the characteristics of the rubber material. For example, the spike-tooth rubber turning head is used to tear and disperse high-viscosity or undispersed rubber materials, the paddle-type rubber turning head is used to gently stir and fold the intermediate-stage compounded rubber material, and the scraper-type rubber turning head is used to scrape up the entire sheet of rubber material on the roller surface and guide it back down during the sheeting stage to achieve overall flipping.

[0023] During operation, the servo motor 6 drives the sliders of the two horizontal linear guides 5 to move synchronously via the synchronous belt transmission assembly 7, thereby driving the vertical lifting mechanism 8 and the rubber turning execution mechanism 11 to move along the roller axis; the cylinder 9 pushes the mounting plate 10 down, so that the rubber turning tool head 15 contacts the rubber material; the drive motor 13 drives the rubber turning tool head 15 to rotate via the transmission shaft 12, turning the rubber material; the magnetic connector 14 allows for quick replacement of the rubber turning tool head 15 to adapt to different turning requirements. The device can be controlled by a programmable logic controller (PLC), which can preset the turning path, speed, and depth to achieve fully automated continuous operation.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
