Description

Technical Field

[0001] This application relates to the field of synchronous belt vulcanization, and in particular to a dual-drum vulcanization device. Background Technology

[0002] The production process of rubber synchronous gears requires the use of a drum vulcanizing machine. When the drum vulcanizing machine is working, the rubber semi-finished product is first led out by the auxiliary machine guide device and enters between the pressure belt and the vulcanizing drum through the lower adjusting roller. The tensioned pressure belt applies vulcanizing pressure to the rubber semi-finished product, and the vulcanizing drum heats the rubber semi-finished product to the vulcanizing temperature. The drive roller drives the pressure belt to move, and through the friction transmission of the pressure belt, it drives the vulcanizing drum and other rollers to rotate. Therefore, under the process conditions of ensuring vulcanizing time, vulcanizing temperature, and vulcanizing pressure, the vulcanization process of the product is completed.

[0003] Existing drum vulcanizing machines have only one vulcanizing drum. In order to facilitate the loading and unloading of rubber semi-finished products, the wrap angle of the vulcanizing drum (the enclosing angle between the pressure band and the two tangent points of the vulcanizing drum) is generally 270°-280°, which affects the vulcanization efficiency. Summary of the Invention

[0004] To address the technical problem of low vulcanization efficiency in drum vulcanizing machines, this application provides a dual-drum vulcanizing device.

[0005] The dual-drum vulcanizing equipment provided in this application adopts the following technical solution:

[0006] A dual-drum vulcanizing device includes a base and a vulcanizing unit mounted on the base. The vulcanizing unit includes a vulcanizing support frame fixed to the upper surface of the base, a pair of horizontally distributed vulcanizing drums rotatably connected to the vulcanizing support frame, a pair of horizontally distributed guide rollers rotatably connected to the vulcanizing support frame, a central pressure roller mechanism, a pair of drive roller mechanisms, a pair of tension roller mechanisms, and a thin steel plate pressure belt. The central pressure roller mechanism includes a central roller support assembly and a central pressure roller rotatably connected to the central roller support assembly. The drive roller mechanism includes a drive roller support assembly, a drive roller rotatably connected to the drive roller support assembly, and a drive roller for driving the drive rollers. The roller drive assembly; the tensioning roller mechanism includes a tensioning roller support assembly and a tensioning roller rotatably connected to the tensioning roller support assembly; a pair of guide rollers are located above a pair of vulcanizing drums and between a pair of guide rollers; a pair of tensioning rollers are located below a pair of vulcanizing drums and between a pair of tensioning rollers; a pair of drive rollers are located between the lower parts of a pair of vulcanizing drums; a central pressure roller is located between the upper parts of a pair of vulcanizing drums; a thin steel plate pressure band is wound around a pair of tensioning rollers, a pair of guide rollers, a pair of vulcanizing drums, a central pressure roller, and a pair of drive rollers.

[0007] By adopting the above technical solution, the rubber semi-finished product enters from the drive roller on one side between the vulcanizing drum and the thin steel plate pressure belt, then passes through the central pressure roller and enters between the thin steel plate pressure belt and another vulcanizing drum, and finally exits from the drive roller on the other side. In this way, the inlet and outlet are both on the lower side between a pair of vulcanizing drums, which allows the wrap angle of the vulcanizing drums on both sides to be set larger, thereby improving the vulcanization efficiency.

[0008] Optionally, the tensioning roller mechanism further includes a tensioning drive assembly disposed on the base; the tensioning drive assembly is used to drive the tensioning roller support assembly to move horizontally.

[0009] By adopting the above technical solution, the tensioning drive assembly drives the tensioning roller support assembly to move horizontally, thereby tensioning or relaxing the thin steel plate pressure belt. When the thin steel plate pressure belt is relaxed, it is convenient to feed the rubber semi-finished product; when the thin steel plate pressure belt is tensioned, it is beneficial to apply pressure to the rubber semi-finished product.

[0010] Optionally, the drive roller mechanism further includes a lifting drive assembly disposed on the base; the tensioning drive assembly is used to drive the drive roller support assembly to move vertically; the drive assembly is disposed on the drive roller support assembly.

[0011] By adopting the above technical solution, when the pressure belt of the thin steel plate is relaxed, the tensioning drive assembly drives the drive roller support assembly to descend, and the drive roller descends at the same time, which is more conducive to the feeding of rubber semi-finished products.

[0012] Optionally, the central pressure roller mechanism further includes a central lifting assembly disposed on the vulcanizing support frame; the central lifting assembly is used to drive the central pressure roller to move vertically.

[0013] By adopting the above technical solution, the central lifting component can drive the central pressure roller to move vertically. In conjunction with the tensioning drive component, the wrap angle of the vulcanizing drum can be adjusted, thus making the vulcanizing equipment more adaptable.

[0014] Optionally, the vulcanizing support frame includes a pair of parallel vulcanizing support plates; the pair of vulcanizing support plates are fixed on the base; a horizontally arranged lower partition is formed between the pair of vulcanizing support plates; the lower partition is located directly below the central pressure roller and directly above the pair of drive rollers; a heat-collecting cavity is formed between the pair of vulcanizing drums, the lower partition, and the thin steel plate pressure band portion on the lower side of the central pressure roller.

[0015] By adopting the above technical solution, the presence of the heat-concentrating cavity makes it difficult for the heat emitted by the two vulcanizing drums to dissipate. In this way, the rubber semi-finished product between the two vulcanizing drums can still be heated, thereby improving the vulcanization efficiency.

[0016] Optionally, the lower partition is detachably and rotatably connected to each end of the pair of vulcanizing drums; the felt rollers correspond one-to-one with the vulcanizing drums and abut against the vulcanizing drums.

[0017] By adopting the above technical solution, the felt rollers clean the surfaces of the two vulcanizing drums simultaneously during their rotation, which facilitates the cleaning of the vulcanizing drums.

[0018] Optionally, a vertically penetrating rectangular clearance hole is formed between the lower parts of a pair of parallel vulcanizing support plates; the lower partition plate is formed between the upper sidewalls of the pair of clearance holes; the lower partition plate is formed with mounting holes near the two ends of the pair of vulcanizing drums for vertical insertion of felt rollers from bottom to top; felt roller rotating columns are formed on the two axial end faces of the felt rollers; vertical mounting grooves with downward openings, U-shaped grooves that mate with the felt roller rotating columns, are formed on the lower end faces of the front and rear sidewalls of the mounting holes; the lower partition plate is formed near the two ends of the pair of vulcanizing drums. Felt roller limiting assemblies are respectively provided on the end faces of the vulcanizing support plate; the felt roller limiting assembly includes a pair of felt roller limiting members; the felt roller limiting member includes a translation limiting seat that is horizontally movably disposed on the lower partition plate and a translation limiting drive member for driving the translation limiting seat to move horizontally; on the end faces of the pair of translation limiting seats of the felt roller limiting assembly that are far apart from each other, U-shaped horizontal placement grooves that cooperate with the felt roller rotating column are respectively formed; when working, the felt roller rotating column is located in the vertical placement groove and the horizontal placement groove on the corresponding side.

[0019] By adopting the above technical solution, when the felt roller is disassembled, the translation limit drive component drives the translation limit seat to move horizontally, thereby causing the felt roller rotating column to disengage from the horizontal mounting groove. When the felt roller rotating columns on both sides of the felt roller are disengaged from the horizontal mounting groove, the felt roller can be moved downwards, thus making the disassembly and assembly of the felt roller convenient.

[0020] Optionally, a pressure band cleaning assembly is provided on the top of the vulcanizing support frame; the pressure band cleaning assembly includes a pressure band cleaning seat, a wire brush roller rotatably connected to the pressure band cleaning seat, and a pressure band cleaning drive for driving the pressure band cleaning seat to move vertically; the wire brush roller is located above the thin steel plate pressure band between a pair of guide rollers.

[0021] By adopting the above technical solution, when it is necessary to clean the thin steel plate pressure belt, the pressure belt cleaning drive unit drives the pressure belt cleaning seat and the wire brush roller to move and descend until the wire brush roller contacts the thin steel plate pressure belt between a pair of guide rollers. In this way, as the thin steel plate pressure belt moves, it drives the wire brush roller to rotate and clean the thin steel plate pressure belt.

[0022] Optionally, the base includes a pair of parallel vertical support plates; a gap is provided between the pair of vertical support plates for an operator to pass through.

[0023] By adopting the above technical solution, operators can feed rubber semi-finished products and perform equipment maintenance between a pair of vertical support plates, making equipment operation and use more convenient.

[0024] Optionally, a winding device is provided between the ends of the pair of vertical support plates near the discharge side; the winding device includes a winding trolley and a winding mechanism disposed on the winding trolley; the winding mechanism is used to wind up the synchronous belt semi-finished product; the winding trolley is movably disposed between the pair of vertical support plates.

[0025] By adopting the above technical solution, during operation, the winding device is located between a pair of vertical support plates, which reduces the floor space occupied by the equipment. The winding mechanism is located on the winding moving trolley, which allows the winding shaft to be replaced outside the pair of vertical support plates, making the winding shaft replacement convenient.

[0026] In summary, the beneficial effects of this application are as follows:

[0027] 1. The feeding and discharging are both located on the lower side between a pair of vulcanizing drums, which allows the wrap angle of the vulcanizing drums on both sides to be set larger, thereby improving vulcanization efficiency.

[0069] Working principle of a dual-drum vulcanizing device:

[0070] The semi-finished rubber product 100 is fed from the drive roller 44, which is away from the winding device 80. The semi-finished rubber product 100 enters between the thin steel plate pressure belt 90 and the vulcanizing drum 70, which is away from the winding device 80. A pair of drive motors 45 drive a pair of drive rollers 44 to rotate, thereby moving the thin steel plate pressure belt 90. The thin steel plate pressure belt 90 drives a pair of vulcanizing drums 70 to rotate through friction, so that the semi-finished rubber product 100 moves along the space between the thin steel plate pressure belt 90 and the pair of vulcanizing drums 70. The thin steel plate pressure belt 90 applies pressure to the semi-finished rubber product 100, and the vulcanizing drums 70 apply heat to the semi-finished rubber product 100. Finally, the vulcanized semi-finished rubber product 100 is discharged from the drive roller 44, which is close to the winding device 80, and finally, it is wound up at the winding device 80.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
