[0001] The invention relates to the technical field of roller deviation correction, in particular to a roller deviation correction device. Background Art

[0002] The roller body is easily deflected due to many factors during use, so a correction device is needed to correct the deviation of the roller body during use.

[0003] The roller correction devices commonly found on the market are usually unable to correct the roller during use, which requires the equipment to be stopped for roller correction, which is cumbersome and affects processing accuracy.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a roller deviation correction device is proposed. Summary of the invention

[0007] Furthermore, the base assembly includes a base seat, a first positioning spring, a mounting frame, an extension platform, a bottom plate and a second positioning spring. The first positioning spring is mounted on both sides of the interior of the base seat, and the outer end of the first positioning spring is connected to the mounting frame. Extension platforms are mounted on both ends of the bottom of the base seat, the bottom end of the mounting frame is provided with a bottom plate, and a second positioning spring is provided between the bottom plate and the extension platform.

[0008] Furthermore, the placement frame is elastically connected to the first position adjusting spring, and the placement frame is elastically connected to the second position adjusting spring via the bottom plate.

[0009] Furthermore, the entry component includes a slide plate, a docking seat, a guide roller and a product. The two ends of the rear of the slide plate are provided with docking seats, and the outer ends of the docking seats are connected to guide rollers, and the outer ends of the guide rollers are wrapped with products.

[0010] Furthermore, the slide plate is integrated with the base seat, and the product is laid on the surface of the slide plate after being wound off the guide roller.

[0011] Furthermore, the roller assembly also includes a motor, a driving gear, a rotating shaft seat, a rotating shaft, an air intake fan, a synchronous belt and a driven gear, the output end of the motor is connected to the driving gear, the outer end of the mounting frame is provided with a rotating shaft seat, and the outer end of the rotating shaft seat is connected to the rotating shaft, the outer end of the rotating shaft is connected to the air intake fan, a synchronous belt is provided between the motor and the rotating shaft, and the outer end of the docking plate is provided with a driven gear.

[0012] Furthermore, the docking plate and the rotating roller are fixed by bolts, and the pressing plate squeezes the rotating roller.

[0013] Furthermore, the clamping plate is fitted with the pressure sensor, and the clamping plate is elastically connected to the return spring.

[0014] Furthermore, the motor drives the rotating shaft to rotate through a synchronous belt, and the rotating shaft is sleeve-connected with the docking plate and the driven gear.

[0015] Furthermore, the docking plate and the driven gear are integrated, and the driven gear is meshed with the driving gear.

[0016] The present invention provides a roller deviation correction device, which has the following beneficial effects:

[0017] The camshaft of the present invention is driven by the synchronous belt to rotate during rotation, and the camshaft is driven to rotate inside the docking plate during rotation. The rotation of the camshaft allows the outside air to enter the docking plate through the one-way air inlet valve. After the air pressure inside the docking plate increases, the pressure plate will stretch the reset spring and fit the rotating roller due to the increased air pressure. Through this operation, the docking plate and the rotating roller can be squeezed and positioned by the pressure plate in addition to being fixed by bolts. The squeezing, positioning and deviation correction of the pressure plate can greatly reduce the situation in which the bolts become loose due to vibration caused by the long-term rotation of the rotating roller, resulting in the virtual position deviation of the rotating roller, which can improve the accuracy. In addition, when the air pressure in the docking plate is too high, the electronically controlled pressure relief valve can be opened to release the pressure, which can avoid damage to equipment parts caused by excessive pressure. In addition, because the air inlet fan is rotated by the rotating shaft driven by the synchronous belt, which is opposite to the rotation direction of the docking plate driven by the driven gear, the air inlet airflow of the air inlet fan will not be affected by the rotation of the docking plate.

[0018] 2. After the pressure plate of the present invention presses the rotating roller, it can fit with the pressure sensor inside the rotating roller. At this time, the pressure sensor can sense the extrusion pressure of the rotating roller. If the bolts between the docking plate and the rotating roller are loose, the pressure sensor will change the intensity of the pressure when being squeezed by the pressure sensor due to the unstable connection between the docking plate and the rotating roller. After the equipment senses a large fluctuation in the pressure sensing value of the pressure sensor, it can control the electric control pressure relief valve to close, which allows the air inlet fan to increase the pressure of the pressure plate by continuously taking in air. Through this operation, the equipment can temporarily increase the clamping force of the pressure plate to realize the deviation correction of the rotating roller when the connection between the docking plate and the rotating roller is unstable. This operation can be performed during the operation of the equipment, which can avoid the tediousness of pausing the equipment for deviation correction and also avoid the effect of the equipment caused by pausing for deviation correction.

[0019] 3. The base seat and the slide plate of the present invention are integrated, and the guide roller is connected to the slide plate through the docking seat. In addition, the bearing seat can be connected to the docking plate and the mounting frame. Through this design, the guide roller and the roller body can be integrated on the mounting frame at the same time, which can avoid the guide roller and the roller body being misaligned due to the deviation of their bearing components when the guide roller and the roller body are installed separately. In addition, thanks to the locking position of the rotating roller by the clamping plate, the deviation of the rotating roller itself can be effectively avoided. Through the cooperation of the two, the anti-bias effect of the equipment can be further improved. In addition, the mounting frame can be adjusted by the first adjustment spring and the second adjustment spring. The spring is connected to the base seat. When the base seat is hit by foreign objects or vibrates accidentally, the mounting frame can effectively absorb the external force through the displacement of the first adjusting spring and the second adjusting spring. In addition, thanks to the fact that the entry assembly and the roller assembly are integrated on the mounting frame at the same time, the mounting frame will not be affected by the position accuracy of the guide roller and the roller body when it is slightly displaced by the first adjusting spring and the second adjusting spring. The suction operation of the first adjusting spring and the second adjusting spring can effectively reduce the impact of external factors, and can also effectively prevent the position accuracy between equipment parts from being affected by external forces.

The entry component 2 includes a slide plate 201, a docking seat 202, a guide roller 203 and a product 204. The two ends of the rear of the slide plate 201 are provided with docking seats 202, and the outer ends of the docking seats 202 are connected to guide rollers 203. The outer ends of the guide rollers 203 are wound with the product 204. The slide plate 201 is integrated with the base seat 101. After the product 204 is wound from the guide rollers 203, it is laid on the surface of the slide plate 201. The roller assembly 3 further includes a motor 308, a driving gear 309, a rotating shaft seat 310, a rotating shaft 311, an air intake fan 312, a synchronous belt 313 and a driven gear 314. The output end of the motor 308 is connected to the driving gear 309. The outer end of the mounting frame 103 is provided with a rotating shaft seat 310, and the outer end of the rotating shaft seat 310 is connected to the rotating shaft 311. The outer end of the rotating shaft 311 is connected to the air intake fan 312. A synchronous belt 313 is provided between the motor 308 and the rotating shaft 311. The outer end of the docking plate 302 is provided with a The driven gear 314, the docking plate 302 and the rotating roller 303 are fixed by bolts, and the pressing plate 307 squeezes the rotating roller 303, the pressing plate 307 fits with the pressure sensor 304, and the pressing plate 307 is elastically connected with the return spring 306, the motor 308 drives the rotating shaft 311 to rotate through the synchronous belt 313, and the rotating shaft 311 is sleeve-connected with the docking plate 302 and the driven gear 314, the docking plate 302 and the driven gear 314 are integrated, and the driven gear 314 is meshed with the driving gear 309;

[0031] The specific operation is as follows. After the staff winds the product 204 out from the surface of the guide roller 203, the product 204 can be laid flat on the slide plate 201. At this time, the staff continues to pull the product 204, so that the product 204 can extend to the bottom end of the roller body 305 and contact the roller body 305. After the preparation work is completed, the motor 308 works to rotate the driving gear 309. Because the driving gear 309 is meshed with the driven gear 314, the driven gear 314 can drive the docking plate 302 to rotate on the inner side of the bearing seat 301. Because the docking plate 302 is docked with the rotating roller 303 through bolts, the rotating roller 303 can rotate, which makes the roller body 305 sleeved on the outer end of the rotating roller 303 drive the product 204 to move. The motor 308 During the rotation, the synchronous belt 313 can drive the rotating shaft 311 to rotate, and the rotating shaft 311 can drive the air intake fan 312 to rotate inside the docking plate 302 during the rotation. The rotation of the air intake fan 312 can allow the external air flow to enter the docking plate 302 through the one-way air intake valve 315. After the air pressure inside the docking plate 302 increases, the pressure plate 307 will stretch the reset spring 306 and fit the rotating roller 303 due to the increased air pressure. Through this operation, in addition to bolt fixation, the docking plate 302 and the rotating roller 303 can also be squeezed and positioned by the pressure plate 307. The squeezing and positioning correction of the pressure plate 307 can greatly reduce the loosening of the bolts due to vibration caused by the long-term rotation of the rotating roller 303. This causes the rotating roller 303 to be skewed, which can improve the accuracy. In addition, when the air pressure in the docking plate 302 is too high, the electronically controlled pressure relief valve 316 can be opened to release the pressure, which can avoid damage to equipment parts caused by excessive pressure. In addition, because the air inlet fan 312 is rotated by the rotating shaft 311 driven by the synchronous belt 313, which is opposite to the rotation direction of the docking plate 302 driven by the driven gear 314, the air flow of the air inlet fan 312 will not be affected by the rotation of the docking plate 302. After the pressing plate 307 presses the rotating roller 303, it can fit with the pressure sensor 304 inside the rotating roller 303. At this time, the pressure sensor 304 can sense the squeezing pressure of the rotating roller 303. If the docking plate 302 and the rotating roller 30 When the bolts between the two ends of the pressure sensor 304 become loose, the strength of the pressure sensor 304 when being squeezed by the pressure sensor 304 will change due to the unstable connection between the docking plate 302 and the rotating roller 303. After the device senses that the pressure sensing value of the pressure sensor 304 has a large fluctuation, it can control the electric control pressure relief valve 316 to close, so that the air intake fan 312 can increase the pressure of the clamping plate 307 by continuously taking in air. Through this operation, the device can temporarily increase the clamping force of the clamping plate 307 to correct the rotation of the rotating roller 303 when the connection between the docking plate 302 and the rotating roller 303 is unstable. This operation can correct the deviation during the operation of the device, which can avoid the tediousness of pausing the device for correction in the middle, and also avoid the effect of the device being affected by the correction in the middle.The base seat 101 and the slide plate 201 are integrated, and the guide roller 203 is connected to the slide plate 201 through the docking seat 202. In addition, the bearing seat 301 can be connected to the docking plate 302 and the mounting frame 103. Through this design, the guide roller 203 and the roller body 305 can be integrated on the mounting frame 103 at the same time, which can avoid the guide roller 203 and the roller body 305 from being misaligned due to the deviation of their bearing components when the guide roller 203 and the roller body 305 are installed separately. In addition, thanks to the locking position of the rotating roller 303 by the clamping plate 307, the rotating roller 303 itself can also be effectively prevented from deflecting. Through the cooperation of the two, the anti-bias effect of the equipment can be further improved. In addition, the mounting frame 103 can be adjusted by the first adjustment spring 10 2 and the second positioning spring 106 are connected with the base seat 101. When the base seat 101 is hit by foreign objects or vibrates unexpectedly, the placement frame 103 can effectively absorb the external force through the displacement of the first positioning spring 102 and the second positioning spring 106. In addition, thanks to the fact that the entry component 2 and the roller body component 3 are integrated on the placement frame 103 at the same time, the placement frame 103 will not affect the position accuracy of the guide roller 203 and the roller body 305 when it is slightly displaced by the first positioning spring 102 and the second positioning spring 106. Due to the suction operation of the first positioning spring 102 and the second positioning spring 106, the influence of external factors can be effectively reduced, and the position accuracy between equipment parts caused by external forces can also be effectively avoided.

[0032] In summary, when the roller deviation correction device is used, the staff first rolls the product 204 out from the surface of the guide roller 203, so that the product 204 can be laid flat on the slide 201. At this time, the staff continues to pull the product 204, so that the product 204 can extend to the bottom end of the roller body 305 and contact the roller body 305. After the preparation work is completed, the motor 308 works to rotate the driving gear 309. Because the driving gear 309 is meshed with the driven gear 314, the driven gear 314 can drive the docking plate 302 to rotate on the inner side of the bearing seat 301. Because the docking plate 302 is docked with the rotating roller 303 through bolts, the rotating roller 303 can rotate, which makes the roller body 305 sleeved on the outer end of the rotating roller 303 drive the product 204 to move.

[0033] Then, during the rotation of the motor 308, the synchronous belt 313 can drive the rotating shaft 311 to rotate, and during the rotation of the rotating shaft 311, the air intake fan 312 can be driven to rotate inside the docking plate 302. Through the rotation of the air intake fan 312, the external air flow can enter the docking plate 302 through the one-way air intake valve 315. After the air pressure inside the docking plate 302 increases, the pressure plate 307 will stretch the reset spring 306 and fit the rotating roller 303 due to the increase in air pressure. Through this operation, in addition to the bolt fixation between the docking plate 302 and the rotating roller 303, the pressure plate 307 can also be used to squeeze and fix. The position of the pressing plate 307 can be corrected by squeezing, positioning and deviation correction, which can greatly reduce the loosening of the bolts due to vibration caused by the long-term rotation of the rotating roller 303, resulting in the virtual position deviation of the rotating roller 303, which can improve the accuracy. In addition, when the air pressure in the docking plate 302 is too high, the electronically controlled pressure relief valve 316 can be opened to release the pressure, which can avoid damage to equipment parts caused by excessive pressure. In addition, because the air intake fan 312 is rotated by the rotating shaft 311 driven by the synchronous belt 313, which is opposite to the rotation direction of the docking plate 302 driven by the driven gear 314, the air intake airflow of the air intake fan 312 will not be affected by the rotation of the docking plate 302.

[0034] After that, after the pressing plate 307 presses the rotating roller 303, it can fit with the pressure sensor 304 inside the rotating roller 303. At this time, the pressure sensor 304 can sense the squeezing pressure of the rotating roller 303. If the bolts between the docking plate 302 and the rotating roller 303 are loose, the pressure sensor 304 will change the strength of being squeezed by the pressure sensor 304 due to the unstable connection between the docking plate 302 and the rotating roller 303. After the equipment senses that the pressure sensing value of the pressure sensor 304 has a large fluctuation, it can control the electric control pressure relief valve 316 to close, so that the air intake fan 312 can increase the pressure of the pressing plate 307 by continuously taking in air. Through this operation, the equipment can temporarily increase the pressing force of the pressing plate 307 to achieve the deviation correction of the rotating roller 303 when the connection between the docking plate 302 and the rotating roller 303 is unstable. This operation can correct the deviation during the operation of the equipment, which can avoid the tediousness of pausing the equipment for correction, and also avoid the effect of the equipment caused by pausing for correction.

[0035] Finally, because the base seat 101 and the slide plate 201 are integrated, and the guide roller 203 is connected to the slide plate 201 through the docking seat 202, in addition, the bearing seat 301 can be connected to the docking plate 302 and the mounting frame 103. Through this design, the guide roller 203 and the roller body 305 can be integrated on the mounting frame 103 at the same time, which can avoid the guide roller 203 and the roller body 305 from being misaligned due to the deviation of their bearing components when the guide roller 203 and the roller body 305 are installed separately. In addition, thanks to the locking position of the pressing plate 307 on the rotating roller 303, the rotating roller 303 itself can also be effectively prevented from deflecting. Through the cooperation of the two, the anti-bias effect of the equipment can be further improved. In addition, the mounting frame 103 can be adjusted by the first adjustment spring 1 02 and the second positioning spring 106 are connected to the base 101. When the base 101 is hit by foreign objects or vibrates accidentally, the mounting frame 103 can effectively absorb the external force through the displacement of the first positioning spring 102 and the second positioning spring 106. In addition, thanks to the fact that the entry component 2 and the roller component 3 are integrated on the mounting frame 103 at the same time, when the mounting frame 103 is slightly displaced by the first positioning spring 102 and the second positioning spring 106, it will not affect the position accuracy of the guide roller 203 and the roller body 305. Due to the suction operation of the first positioning spring 102 and the second positioning spring 106, the influence of external factors can be effectively reduced, and the position accuracy between equipment parts caused by external forces can also be effectively avoided.
