Description

Technical Field

[0001] This utility model relates to the technical field of tire processing, and in particular to a two-roll hot refining machine. Background Technology

[0002] Aviation tire rubber compounds (such as natural rubber / high styrene-butadiene rubber blends) require high temperature and high pressure molding.

[0003] In the prior art, patent document CN211221533U discloses a two-roll open mill, including an open mill body and two rollers installed on the open mill body for plasticizing or mixing rubber materials. It also includes two scraping devices that are arranged one-to-one with the rollers for cutting the rubber materials adhering to the rollers, and each of the scraping devices is connected to a conveying device for conveying the rubber materials cut by the scraping devices.

[0004] During use, it was found that the above-mentioned device requires workers to fold and move the rubber material left and right using tools, and then the two sets of rollers mix the molded rubber material, which affects the processing efficiency and increases the labor intensity of the workers. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a twin-roll hot refining mill.

[0006] This utility model discloses a two-roll hot refining mill, comprising a main body, a controller, and hot refining rolls. Two sets of hot refining rolls are mounted on the main body for hot refining of rubber compound. A controller is located at the front end of the main body, which also includes a lifting component, a moving component, and a mixing component. A lifting component is located at the top of the main body, used for adjusting the height of the moving component and for the left-right reciprocating movement of the two mixing components. In use, the controller causes the two sets of hot refining rolls to rotate in opposite directions, placing the rubber compound between the two controllers. The two controllers heat the rubber compound while extruding it into sheets. The bottom end of the sheet rubber compound is then passed around one of the front sets of hot refining rolls and re-enters the space between the two sets of hot refining rolls, transforming the sheet rubber compound into a sealed annular shape. The lifting component is operated to lower the moving component, activating the mixing components. The two mixing components fold the left and right ends of the sealed annular rubber compound, and the two sets of hot refining rolls re-extrude the folded annular rubber compound, improving mixing efficiency.

[0007] Preferably, the lifting assembly includes a vertical pole, a top plate, a servo electric cylinder, and a U-shaped frame. The top of the hot refining mill body is provided with a vertical pole, the top of which is connected to the bottom of the top plate. A servo electric cylinder is installed on the top of the top plate, and the bottom moving end of the servo electric cylinder extends to the bottom of the top plate and is connected to the top of the U-shaped frame. The moving assembly is installed inside the U-shaped frame. After the rubber compound is placed, the controller operates the servo electric cylinder to extend, thereby causing the U-shaped frame to move the mixing assembly between the two sets of hot refining rollers through the moving assembly, and folding and mixing the rubber compound left and right.

[0008] Preferably, the moving assembly includes a first motor, a reciprocating screw, a moving block, a round shaft, and a second guide rod. A set of reciprocating screws is installed at each end of the round shaft, and the two sets of reciprocating screws are rotatably mounted inside the U-shaped frame. A second guide rod is installed inside the U-shaped frame. Each set of reciprocating screws is threadedly connected to a set of moving blocks, and both sets of moving blocks are slidably connected to the second guide rod. A first motor is installed on the U-shaped frame, and the output end of the first motor is connected to one end of a set of reciprocating screws. A mixing component is installed at the bottom of each set of moving blocks. Starting the first motor causes the two sets of reciprocating screws to rotate synchronously, further causing the two sets of moving blocks, in cooperation with the second guide rod, to drive the corresponding mixing components to reciprocate left and right. The two sets of mixing components cooperate to fold the annular rubber material on the outer side of the hot refining rollers on both sides, thereby causing the two sets of hot refining rollers to mix and extrude the material.

[0009] Preferably, the mixing assembly includes a second motor, a rotating shaft, and a mixing head. The second motor is located at the bottom of the moving block, and the rotating shaft is located at the output end of the second motor. The mixing head is located at the bottom of the rotating shaft, and the outer wall of the mixing head is adapted to the outer wall of the hot refining roller. When the mixing head moves between the two sets of hot refining rollers and the outer wall of the mixing head contacts the outer walls of the two sets of hot refining rollers, the second motor is started. This causes the rotating shaft to drive the mixing head to rotate rapidly, while the moving block drives the mixing head to move laterally between the two sets of hot refining rollers. This causes the two sets of mixing heads to fold the annular rubber compound left and right, and the two sets of hot refining rollers to squeeze the folded part of the rubber compound again, thus achieving mixing.

[0010] Preferably, it also includes a first optical bar, which is provided at the top of the U-shaped frame and is slidably connected to the top plate; the servo electric cylinder drives the U-shaped frame to rise and fall stably with the cooperation of the first optical bar, thereby improving stability.

[0011] Preferably, it also includes adjustable feet, with a set of adjustable feet provided at each of the four corners of the bottom of the hot refining mill body; the four sets of adjustable feet work together to provide stable support for the hot refining mill body and improve stability.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the controller makes two sets of hot refining rollers rotate in opposite directions, and the rubber material is placed between the two sets of controllers. The two sets of controllers heat the rubber material and extrude it into sheets. Then, the bottom end of the sheet rubber material passes around the front set of hot refining rollers and enters the space between the two sets of hot refining rollers again. The sheet rubber material becomes a ring-shaped sealed rubber material. The lifting component is operated to move the moving component down and start the mixing component. The two sets of mixing components fold the left and right ends of the ring-shaped sealed rubber material. The two sets of hot refining rollers re-extrude the folded ring-shaped sealed rubber material, thereby improving the mixing efficiency. Attached Figure Description
