[0038] Please see Figures 1-5 An automatic separation and correction assembly for a blanket 100 is installed inside a printing machine. The printing machine has a left end plate 1 and a right end plate 2 arranged opposite to each other. It includes a separation mechanism 4 and a correction mechanism 3. Both the separation mechanism 4 and the correction mechanism 3 are installed between the left end plate 1 and the right end plate 2, and the separation mechanism 4 is located above the correction mechanism 3.

[0039] A main motor 6 is mounted on the outer side of the left end plate 1 via a fixing frame 5. A main gear 7 is sleeved on the shaft of the main motor 6. The main gear 7 is connected to a main drive gear 9 via a main chain 8. A main shaft 10 is connected to the inner wall of the main drive gear 9. The two ends of the main shaft 10 are rotatably mounted on the left end plate 1 and the right end plate 2 via bearings, respectively. The main shaft 10, the correction mechanism 3, and the separation mechanism 4 are all tumblingly connected to the blanket 100. When the main motor 6 is working, it drives the main gear 7, the main chain 8, and the main drive gear 9 to rotate via its shaft, thereby driving the main shaft 10 to rotate, which in turn drives the blanket 100 to roll and transfer.

[0040] Please see Figures 1-4 , Figure 6 and Figure 7The correction mechanism 3 includes a fixed bracket 31, two first mounting seats 32, and two first guide plates 33. The fixed bracket 31 is fixedly installed on the outer side of the right end plate 2. A correction motor 301 is installed on one side of the fixed bracket 31. One end of the shaft of the correction motor 301 passes through the fixed bracket 31 and is fitted with a first gear 302. The first gear 302 is connected to a second gear 304 through a first chain 303. The two first mounting seats 32 are fixedly installed on the outer side of the right end plate 2. The inner walls of the two first mounting seats 32 are provided with rotatable first lead screws 305 through bearings. One end of the first lead screw 305 is fitted with a second gear 304. The first gear 302 is driven to rotate by the shaft of the correction motor 301. The first gear 302 drives the second gear 304 to rotate through the first chain 303. The second gear 304 drives the first lead screw 305 to rotate.

[0041] A nut 306 is fitted onto the first lead screw 305, and a correction plate 307 is fitted onto the nut 306. The correction plate 307 is slidably disposed on the inner side of the two first guide plates 33, which are fixedly installed on the outer side of the right end plate 2. One end of a correction shaft 308 is fitted onto the inner wall of the correction plate 307 through a bearing. The correction shaft 308 is tumbledly connected to the blanket 100 and is used to correct the offset of the blanket 100 on the main rotating shaft 10. The rotation of the first lead screw 305 drives the nut 306 to move. Through the cooperation between the nut 306 and the first lead screw 305, the correction plate 307 moves along the direction of the first lead screw 305, thereby enabling the correction plate 307 to drive the correction shaft 308 to move along the direction of the first lead screw 305.

[0042] The other end of the correction shaft 308 is fitted with an adjusting block 309 via a bearing. A push rod 310 is fixedly connected to one side of the adjusting block 309. A cylinder (not shown in the figure) is driven to the end of the push rod 310 away from the adjusting block 309. The cylinder (not shown in the figure) is installed on the printing machine or on the outer side of the left end plate 1. A first guide seat 311 is fitted on the push rod 310. The first guide seat 311 is fixedly installed on the outer side of the left end plate 1 and guides the movement of the push rod 310. Two second guide plates 312 are slidably connected to both sides of the adjusting block 309. The two second guide plates 312 are fixedly installed on the inner side of the left end plate 1. The two first guide plates 33 and the two second guide plates 312 guide the movement of the correction plate 307 and the adjusting block 309, respectively.

[0043] A first bevel gear 313 is fitted onto one end of the first lead screw 305 relative to the correction plate 307. The first bevel gear 313 meshes with a second bevel gear 314. A first rotating rod 315 is provided on the inner wall of the second bevel gear 314. The first rotating rod 315 is rotatably mounted on the right end plate 2 via bearings. A third gear 316 is fitted onto the inner side of the first rotating rod 315 on the right end plate 2. The third gear 316 is connected to a fourth gear 318 via a second chain 317. A correction bracket 319 is also fixedly installed on the inner side of the right end plate 2. Two second mounting seats 320 are installed at both ends of the bottom of the correction bracket 319. A rotatable second lead screw 321 is mounted on the inner wall of the mounting base 320 via bearings. A fourth gear 318 is sleeved on one end of the second lead screw 321, and a correction block 322 that cooperates with it is mounted on the second lead screw 321. A sensing device 323 is provided at the bottom of the correction block 322. The sensing device 323 is used to detect the position of the blanket 100 in real time. The sensing device 323 can be a sensor or the like. A baffle plate 327 is also provided on the inner side of the right end plate 2, located on one side of the second chain 317. The baffle plate 327 is used to protect the operation of the second chain 317 from being disturbed by other accessories, ensuring the stability and reliability of the operation.

[0044] The sensor 323 detects whether the blanket 100 has shifted position on the correction shaft 308, triggering the correction motor 301 to drive the first gear 302, first chain 303, second gear 304, and first lead screw 305 to rotate synchronously. The rotation of the first lead screw 305 causes the nut 306 to move, which in turn causes the correction plate 307 to move, thereby moving the correction shaft 308 to correct the blanket 100's rolling deviation. Simultaneously with the triggering of the correction motor 301, the first bevel gear 313 drives the second bevel gear 314 to rotate synchronously, and the second bevel gear 314 drives the first rotating rod 3... When the first rotating rod 315 rotates, it drives the third gear 316 to rotate. The third gear 316 drives the fourth gear 318 to rotate via the second chain 317. The fourth gear 318 drives the second lead screw 321 to rotate. The second lead screw 321 drives the correction block 322 to move, thereby moving the correction block 322 to the correction position to adjust and correct the rolling position of the blanket 100 on the correction shaft 308. At the same time, the adjusting block 309 at the other end of the correction shaft 308 is adjusted by a cylinder. In conjunction with the movement adjustment of the correction plate 307, the blanket 100 offset can be accurately corrected, ensuring the printing quality.

[0045] The left end plate 1 and the right end plate 2 are provided with oblique rectangular guide holes 326. Two first guide plates 33 are installed on the symmetrical sides of the rectangular guide holes 326, and two first mounting seats 32 are installed on the other symmetrical sides of the rectangular guide holes 326. The two first guide plates 33 and the two first mounting seats 32 are set perpendicularly. The correction shaft 308 passes through the rectangular guide holes 326. The rectangular guide holes 326 provide space for the movement of the correction shaft 308. The oblique rectangular guide holes 326 make the movement direction of the correction shaft 308 oblique. This movement can improve the rapid correction of the correction shaft 308 and the blanket 100, and improve the correction efficiency by 30% compared with the traditional lateral movement.

[0046] In addition, a bending plate 324 is installed on the outer side of the right end plate 2, on one side of the correction plate 307. Two position detection devices 325 are installed on the bending plate 324. The position detection devices 325 can be formed switches or proximity switches 422, etc., to detect the movement position of the correction plate 307, identify the movement position of the correction plate 307 in real time, so that the operator can know it, and also prevent the correction plate 307 from moving excessively.

[0047] Please see Figure 1 , Figure 3 , Figure 4 , Figures 8-10 The separation mechanism 4 includes a mounting bracket 41, which is fixedly installed on the outside of the right end plate 2. A separation motor 401 is installed on one side of the mounting bracket 41. The shaft of the separation motor 401 passes through the mounting bracket 41 and is fitted with a fifth gear 402. The fifth gear 402 is connected to a sixth gear 404 through a third chain 403. The separation motor 401 drives the fifth gear 402 to rotate, and the fifth gear 402 drives the sixth gear 404 to rotate synchronously through the third chain 403.

[0048] A gearbox 405 is mounted on the mounting bracket 41. A gearbox shaft 406 is installed inside the top of the gearbox 405. A sixth gear 404 is sleeved on one end of the gearbox shaft 406. A second rotating rod 407 is provided inside the gearbox 405 and is connected to the gearbox shaft 406. The two ends of the second rotating rod 407 are rotatably mounted on the left end plate 1 and the right end plate 2 through bearings. The second rotating rod 407 is located on the inner side (proximate side) of the left end plate 1 and the right end plate 2, respectively, with a left drive gear 408 and a right drive gear 411 sleeved on each side. Two left slide rails 409 and two right slide rails 412 are provided on the inner side of the left end plate 1 and the right end plate 2, respectively. A left rack plate 410 is slidably connected between the two left slide rails 409. The top of the left rack plate 410 is engaged with the left drive gear 408. A right rack plate 413 is slidably connected between the two right slide rails 412. The right rack plate 413 is engaged with the right drive gear 411.

[0049] The inner walls of the left rack plate 410 and the right rack plate 413 are provided with a rotatable separation shaft 414 via bearings. The separation shaft 414 is tumbledly connected to the blanket 100 and is used to separate the blanket 100 from the main rotating shaft 10. The inner sides of the left end plate 1 and the right end plate 2 are also provided with a left support block 415 and a right support block 416. The top of the left support block 415 slides against the left rack plate 410, providing support and guidance for the left rack plate 410. The top of the right support block 416 slides against the right rack plate 413, providing support and guidance for the right rack plate 413.

[0050] When the sixth gear 404 rotates, it drives the transmission shaft 406 to rotate, which in turn drives the second rotating rod 407 to rotate. The second rotating rod 407 drives the left transmission gear 408 and the right transmission gear 411 to rotate synchronously. The left transmission gear 408 and the right transmission gear 411 drive the left rack plate 410 and the right rack plate 413 to move synchronously on the left slide rail 409 and the right slide rail 412, respectively. This drives the separation shaft 414 to move synchronously on the left slide rail 409 and the right slide rail 412, thereby separating the blanket 100 from the entire contact surface on the main rotating shaft 10. The separation efficiency is high and the separation is thorough, effectively avoiding manual partial separation and effectively preventing the problem of blanket 100 sticking together.

[0051] Please see Figures 8-10 A universal joint 417 is fitted at the other end of the gearbox 406. A manual lever 418 is fixedly connected to one end of the universal joint 417 relative to the gearbox 405. A hand crank 419 is fitted at one end of the manual lever 418 relative to the universal joint 417. A second guide seat 420 is also fitted on the manual lever 418. The second guide seat 420 is installed on the outside of the printing machine and provides support and guidance for the manual lever 418. When the internal working of the separation motor 401 fails, and it is necessary to separate the blanket 100, the separation mechanism 4 can be manually operated. The hand crank 419, when manually rotated, drives the manual lever 418, universal joint 417, and gearbox 406 to rotate, thereby driving the second rotating lever 407 and the left and right transmission gears 411 to rotate synchronously. The left and right transmission gears 411 drive the left and right rack plates 413 to move synchronously on the left and right slide rails 412, thereby driving the separation shaft 414 to move synchronously on the left and right slide rails 412. This makes it easy for the operator to know the position of the separation shaft 414 and also prevents the left and right rack plates 413 from moving excessively.

[0052] In addition, two sensing brackets 421 are installed on the outer side of the left end plate 1. Two proximity switches 422 are installed on the two sensing brackets 421 respectively. Two detection holes 423 are opened on the left end plate 1 on one side of the two proximity switches 422 respectively. The two proximity switches 422 are used to detect the moving position of the left rack plate 410 in real time, that is, to detect the moving position of the left rack plate 410 and the right rack plate 413 in real time, that is, to detect the moving position of the separation shaft 414 in real time.

[0053] Please see Figures 8-11 The left rack plate 410 and the right rack plate 413 are both integrally connected elongated plates 424 and square plates 425. The top of the elongated plate 424 has a rack shape and meshes with the left transmission gear 408 and the right transmission gear 411 respectively. The bottom of the elongated plate 424 slides against the left support block 415 and the right support block 416 respectively. The square plates 425 abut against the two left slide rails 409 and the two right slide rails 412 respectively. The inner walls of the two square plates 425 are provided with rotatable separation shafts 414 through bearings. The bearings can reduce the friction between the components and improve the transmission efficiency and service life.

[0054] The working principle of this utility model is as follows:

[0055] When working, the main motor 6 starts, and drives the main shaft 10 to rotate through the main gear 7, main chain 8, and main transmission gear 9. The main shaft 10 drives the blanket 100 to roll and transfer.

[0056] When the sensing device 323 detects a shift in the blanket 100, it sends a signal to the control system (not shown in the figure). The control system then activates the correction motor 301. The correction motor 301 drives the first gear 302 to rotate. The first gear 302 drives the second gear 304 to rotate via the first chain 303. The second gear 304 drives the first lead screw 305 to rotate. The nut 306 moves on the first lead screw 305, causing the correction plate 307 to slide along the first guide plate 33. The correction plate 307 then moves the correction shaft 308. Simultaneously, a cylinder (not shown in the figure) drives the push rod 310 to move, causing the adjusting block 309 to slide along the second guide plate 312. The adjusting block 309 then moves the other end of the correction shaft 308. Under the action, the offset of the blanket 100 is corrected; at the same time, the rotation of the first lead screw 305 drives the first bevel gear 313 to rotate, the first bevel gear 313 drives the second bevel gear 314 to rotate, the second bevel gear 314 drives the first rotating rod 315 to rotate, the first rotating rod 315 drives the third gear 316 to rotate, the third gear 316 drives the fourth gear 318 to rotate through the second chain 317, the fourth gear 318 drives the second lead screw 321 to rotate, the correction block 322 moves on the second lead screw 321, and drives the sensing device 323 to follow the blanket 100 to move until the sensing device 323 moves to the correction position, so as to realize the position correction of the blanket 100. At the same time, the sensing device 323 can continuously detect the position of the blanket 100.

[0057] When it is necessary to separate the blanket 100 from the main rotating shaft 10, the separation motor 401 starts, driving the fifth gear 402 to rotate. The fifth gear 402 drives the sixth gear 404 to rotate via the third chain 403. The sixth gear 404 drives the gear shift shaft 406 to rotate. The gear shift shaft 406 drives the second rotating rod 407 to rotate. The second rotating rod 407 drives the left transmission gear 408 and the right transmission gear 411 to rotate. The left transmission gear 408 drives the left rack plate 410 along the left slide rail 4. 09. The right transmission gear 411 drives the right rack plate 413 to move along the right slide rail 412. The left rack plate 410 and the right rack plate 413 drive the separation shaft 414 to move synchronously. The separation shaft 414 separates the blanket 100 from the main rotating shaft 10. The proximity switch 422 detects the moving position of the left rack plate 410 through the detection hole 423. When the left rack plate 410 moves to the set position, it sends a signal to the control system. The control system controls the separation motor 401 to stop working.
