[0017] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The roller adjustment mechanism of the oil seal rubber open mill involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Reference Figures 1 to 5This utility model provides a roller adjustment mechanism for an oil seal rubber open mill, including an open mill body 1, and further including: an adjustment mechanism 2 and a roller mechanism 3. The side of the open mill body 1 is fixedly connected to the side of the roller mechanism 3, and the side of the adjustment mechanism 2 is movably connected to the inner wall of the side of the roller mechanism 3. The open mill body 1 includes a side plate 101, and a roller 102 is movably sleeved on the side of the side plate 101. The roller mechanism 3 includes a connecting frame 306, the side of the connecting frame 306 is fixedly connected to the side of the side plate 101, and a mounting frame 301 is movably connected to the side of the connecting frame 306 by a pin. A pneumatic telescopic mechanism is movably connected to the side of the side plate 101 by a pin. The pneumatic telescopic rod 303 is movably connected to the side of the mounting bracket 301 via a pin. A groove 311 is formed on the inner wall of the bottom end of the mounting bracket 301. The adjusting mechanism 2 includes a slider 201, the bottom end of which is movably connected to the bottom end of the groove 311. A through hole 210 is formed on the side of the slider 201, and a mounting groove 211 is formed on the side of the through hole 210. A threaded block 203 is movably sleeved on the side of the mounting groove 211. A threaded shaft 202 is threadedly connected to the inner wall of the side of the threaded block 203. The side of the threaded shaft 202 is movably sleeved on the side of the mounting bracket 301. A servo motor 20 is fixedly connected to the side of the mounting bracket 301. 5. The output shaft of the servo motor 205 is fixedly connected to the side of the threaded shaft 202. The top of the slider 201 is movably sleeved with the mounting shaft 307. The side of the mounting shaft 307 is fixedly sleeved with the hob body 305. The slide groove 311 is provided with multiple adjustment mechanisms 2. The threaded block 203 is a cylindrical structure that can rotate inside the mounting groove 211. It is fixed inside by a second electromagnetic component 209. When the position of the hob body 305 does not need to be adjusted, the second electromagnetic component 209 does not fix the threaded block 203. The threaded block 203 rotates with the threaded shaft 202 and cannot drive the slider 201 to move laterally. When the position needs to be adjusted... The corresponding second electromagnetic component 209 of the cutter body 305 fixes the threaded block 203. The servo motor 205 is started to drive the threaded shaft 202 to rotate. Through the thread, the threaded block 203 drives the slider 201 to move laterally along the slide groove 311, so that the cutter body 305 moves to a suitable position, thereby realizing the adjustment of the position of each cutter body 305. The pneumatic telescopic rod 303 pushes the mounting frame 301 to rotate along the side pin of the connecting frame 306, so that the cutter body 305 moves closer to the roller 102 to cut the rubber. After the cutting is completed, the pneumatic telescopic rod 303 retracts to move the cutter body 305 away from the roller 102 and stop cutting.

[0019] The mounting bracket 301 has a drive motor 304 fixedly connected to its side. The output shaft of the drive motor 304 is fixedly connected to a transmission shaft 302. The mounting shaft 307 has a slot 308 on its side. The side of the slot 308 meshes with the side of the transmission shaft 302. The transmission shaft 302 has a rhomboid structure. During the movement of the cutter body 305, the slot 308 slides along the transmission shaft 302. During the cutting process, the drive motor 304 drives the transmission shaft 302 to rotate. The meshing of the transmission shaft 302 and the slot 308 causes the mounting shaft 307 to drive the cutter body 305 to rotate and cut the rubber.

[0020] The mounting groove 211 has a third mounting hole 213 on its side, and a second electromagnetic component 209 is fixedly connected to the side of the third mounting hole 213. A fourth mounting hole 214 is provided on the side of the third mounting hole 213 corresponding to the position of the second electromagnetic component 209. A fixing hole 212 is provided on the side of the threaded block 203 corresponding to the position of the second electromagnetic component 209. When the position of the hob body 305 needs to be adjusted, the second electromagnetic component 209 is inserted into the fixing hole 212 to fix the threaded block 203. When the position of the hob body 305 does not need to be adjusted, the second electromagnetic component 209 is moved out of the fixing hole 212, and the threaded block 203 rotates with the threaded shaft 202, preventing the slider 201 from moving laterally.

[0021] The bottom end of the slider 201 is fixedly connected to a grating sensor 208, and the bottom inner wall of the mounting bracket 301 is fixedly connected to a scale grating 310 corresponding to the position of the grating sensor 208. During the movement of the slider 201, the scale grating 310 is scanned by the grating sensor 208 to determine the position of the corresponding hob body 305, so as to facilitate the adjustment of the hob body 305.

[0022] The mounting bracket 301 has a positioning rack 309 fixedly connected to the inner wall of its bottom end. The bottom end of the slider 201 has a first mounting hole 206. The side of the first mounting hole 206 is fixedly connected to a first electromagnetic component 204. The top of the first mounting hole 206 has a second mounting hole 207 corresponding to the position of the first electromagnetic component 204. When the position of the hob body 305 needs to be adjusted, the first electromagnetic component 204 separates from the positioning rack 309, allowing the slider 201 to move laterally. When the position of the hob body 305 does not need to be adjusted, the first electromagnetic component 204 and the positioning rack 309 mesh with each other to position the slider 201 and prevent lateral movement.

[0023] The structure of the first electromagnetic component 204 is the same as that of the second electromagnetic component 209. The first electromagnetic component 204 includes a fixing pin 2041, and a connecting rod 2044 is fixedly connected to the top end of the fixing pin 2041. The top end of the connecting rod 2044 is fixedly connected to the top end of the first mounting hole 206. The bottom end of the fixing pin 2041 is provided with a toothed groove. When it is not necessary to adjust the position of the slider 201, the connecting rod 2044 pushes the fixing pin 2041 downward, so that the bottom toothed groove of the fixing pin 2041 meshes with the positioning rack 309 to fix the slider 201.

[0024] An electromagnet 2042 is fixedly connected to the top of the second mounting hole 207, a return spring 2045 is fixedly connected to the top of the fixing pin 2041, and an iron plate 2043 is fixedly connected to the top of the return spring 2045. When the position of the corresponding hob body 305 needs to be adjusted, the electromagnet 2042 generates magnetic force through the internal power supply, which attracts the iron plate 2043, causing the return spring 2045 to drive the fixing pin 2041 to move upward and separate from the positioning rack 309, allowing the slider 201 to move freely.

[0025] The working principle of this utility model is as follows: When the position of the hob body 305 needs to be adjusted according to usage requirements, the electromagnet 2042 inside the corresponding slider 201 generates magnetic force through internal power supply, which attracts the iron plate 2043, causing the return spring 2045 to drive the fixing pin 2041 to move upward and separate from the positioning rack 309, allowing the slider 201 to move freely. The second electromagnetic component 209 inside the slider 201 is de-energized and inserts into the fixing hole 212 to fix the threaded block 203. For other hob bodies 305 that do not require position adjustment, the electromagnet 2042 inside the corresponding slider 201 is de-energized, the connecting rod 2044 pushes the fixing pin 2041 downward, so that the bottom tooth groove of the fixing pin 2041 meshes with the positioning rack 309 to fix the slider 201. The second electromagnetic component 209 is energized, causing the second electromagnetic component 209 to move out of the fixing hole 212, allowing the threaded block 203 to move with the threaded shaft 202. The position cannot be changed by rotation within the mounting slot 211. The servo motor 205 is started to drive the threaded shaft 202 to rotate. The threaded block 203 drives the slider 201 to move laterally along the slide groove 311 through the thread. During the movement of the slider 201, the grating sensor 208 scans the scale grating 310 to determine the position of the corresponding roller body 305, so that the adjacent roller bodies 305 maintain a suitable distance, and the excess roller bodies 305 move to both sides of the mounting frame 301 and do not participate in cutting. The pneumatic telescopic rod 303 is started to push the mounting frame 301 to rotate along the side pin of the connecting frame 306, so that the roller body 305 is close to the roller 102. At the same time, the drive motor 304 drives the transmission shaft 302 to rotate. Through the meshing of the transmission shaft 302 and the slot 308, the mounting shaft 307 drives the roller body 305 to rotate and cut the rubber. After the cutting is completed, the pneumatic telescopic rod 303 retracts to move the roller body 305 away from the roller 102 and stop cutting.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
