Description

Technical Field

[0001] The utility model relates to the field of mixing devices, in particular to a rubber mixing device. Background Art

[0002] When processing rubber products, a rubber mixing mill is usually used to mix rubber materials. The rubber mixing mill generally consists of a frame, two pressure rollers, a driving mechanism and a cutting mechanism.

[0003] The driving mechanism drives the two pressure rollers to rotate relative to each other to press the rubber material. After the rubber material is pressed and mixed, the cutting mechanism is used to cut the rubber material to a fixed width, so that the rubber material forms a certain width for subsequent processing.

[0004] The existing cutting mechanism usually includes a carrying rod, a mounting plate and a cutting tool. When the mounting plate rotates relative to the carrying rod, the cutting tool can move towards or away from the pressure roller. And when the mounting plate drives the cutting tool to work, the mounting plate is usually locked on the carrying rod by bolts. However, in this locked state, when the cutting tool is extruded by the rubber material, the mounting plate will rotate relative to the carrying rod, resulting in the cutting tool moving away from the pressure roller, and then the cutting tool cannot cut the side of the rubber material, thus reducing the stability of the cutting tool during operation.

Specific implementation manner

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The present invention provides a rubber mixing device as Figures 1-3 shown, which includes a rubber mixing machine 1. The rubber mixing machine 1 includes a frame 11 and a pressing roller 12. The pressing roller 12 is rotatably installed inside the frame 11, and a motor and gears for driving the two pressing rollers 12 to move relatively are installed on the frame 11, so that the two pressing rollers 12 rotate to press the rubber material. A cutting component 2 is arranged on the frame 11. The cutting component 2 includes a first mounting rod 21, a second mounting rod 22, a mounting plate 23, a cutting tool 24 and a locking component 25. The first mounting rod 21 and the second mounting rod 22 are parallelly installed inside the frame 11. The cutting tool 24 is rotatably installed at the end of the mounting plate 23. The mounting plate 23 is slidably arranged outside the first mounting rod 21 and the second mounting rod 22. When the two mounting plates 23 move along the axis of the first mounting rod 21 and the second mounting rod 22, the distance between the two cutting tools 24 can be changed. When the mounting plate 23 moves along the perpendicular line of the axis of the first mounting rod 21 and the second mounting rod 22, the cutting tool 24 can move towards or away from the pressing roller 12. The locking component 25 is arranged inside the mounting plate 23. The locking component 25 is used to lock the mounting plate 23 outside the first mounting rod 21 and the second mounting rod 22. And under the action of the locking component 25, the mounting plate 23 can be stably installed outside the first mounting rod 21 and the second mounting rod 22, so that the cutting tool 24 is in a stable state to quantitatively cut the rubber material outside the pressing roller 12.

[0027] In particular, the locking component 25 includes a connecting collar 251, an adjusting screw 252 and a brake pad 253. The connecting collar 251 is slidably sleeved outside the first mounting rod 21. A threaded hole matching the adjusting screw 252 is provided at the end of the mounting plate 23. One end of the adjusting screw 252 is rotatably connected to the connecting collar 251, that is, a connecting sleeve is fixedly connected to one side of the connecting collar 251, and one end of the outer wall of the adjusting screw 252 is rotatably connected to the connecting sleeve. Thus, by rotating the adjusting screw 252, the adjusting screw 252 can drive the mounting plate 23 to move towards the pressure roller 12, so that the cutting tool 24 can be butted against the pressure roller 12 to cut the rubber product. The brake pad 253 is embedded inside the mounting plate 23 and corresponds to the second mounting rod 22. A first sliding hole 254 is provided on one side of the mounting plate 23, and the outer wall of the second mounting rod 22 is slidably sleeved in the inner cavity of the first sliding hole 254. The brake pad 253 is fixedly embedded on one side of the inner wall of the first sliding hole 254. And when the mounting plate 23 moves towards the pressure roller 12, the brake pad 253 inside the mounting plate 23 can be pressed against and fitted with the second mounting rod 22, so as to brake the mounting plate 23, thereby ensuring the stability of the mounting plate 23 mounted outside the first mounting rod 21 and the second mounting rod 22.

[0028] Furthermore, a second sliding hole 255 matching the first mounting rod 21 is provided on one side of the mounting plate 23, and the length of the second sliding hole 255 is greater than that of the first sliding hole 254. Thus, when the mounting plate 23 slides relative to the first mounting rod 21 and the second mounting rod 22, the mounting plate 23 first fits with the second mounting rod 22 through the inner wall of the first sliding hole 254. A connecting groove 256 is provided on the inner wall of the second sliding hole 255, and the outer wall of the connecting collar 251 is slidably clamped in the inner cavity of the connecting groove 256. Under the limitation of the connecting groove 256, the mounting plate 23 can drive the connecting collar 251 to slide on the first mounting rod 21. A locking nut 257 is threadedly sleeved on the outer wall of the adjusting screw 252, and the locking nut 257 is pressed against and fitted with the end of the mounting plate 23. The other end of the adjusting screw 252 is fixedly connected with a turntable 258. The turntable 258 can drive the adjusting screw 252 to rotate, and the locking nut 257 can lock the adjusting screw 252.

[0029] Specifically, fixed collars 27 are slidably sleeved on the ends of the outer walls of the first mounting rod 21 and the second mounting rod 22. A fixing plate 26 is fixedly connected to one side of the fixed collar 27. A fixing bolt is provided on one side of the fixing plate 26. The fixing plate 26 is fixedly connected to the frame 11 through the fixing bolt. By removing the fixing bolt, the two fixing plates 26 can be removed from the frame 11, and then the first mounting rod 21 and the second mounting rod 22 can be detached from the fixed collar 27, so as to disassemble and maintain the mounting plate 23.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
