[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] like Figure 1-8 As shown, a printing roller cooling device for non-woven fabrics comprises:

[0038] Two printing rollers 1 are arranged in parallel, and the two printing rollers 1 are used to heat-roll the multiple cloth embryos passing through to form a synthetic non-woven fabric;

[0039] The hard shell separation mechanism 4 includes a rotating sleeve 42, a plurality of separation rods 43 slidably connected to the rotating sleeve 42 in a circular array, and a fixed cam shaft 41 disposed in the rotating sleeve 42. The first end of the separation rod 43 is provided with a toggle point 431;

[0040] The separation rod 43 slides back and forth along the fixed cam shaft 41 as the rotating sleeve 42 rotates, so as to drive the toggle point 431 to slide along the printing roller 1 toward the non-woven fabric.

[0041] Specifically, the two printing rollers 1 are used to heat-roll the synthetic non-woven fabrics passing through the multiple cloth embryos. The hard shell separation mechanism 4 includes a rotating sleeve 42. The rotating sleeve 42 is slidably connected to multiple separation rods 43 in a circumferential array. A fixed cam shaft 41 is provided in the rotating sleeve 42. The fixed cam shaft 41 is fixed and does not move. The first end of the separation rod 43 (with Figure 4 For reference, the end away from the fixed cam shaft 41 is the first end, and the end close to the fixed cam shaft 41 is the second end) is provided with a toggle sharp corner 431, and the toggle sharp corner 431 is made of a metal elastic sheet with an outer layer wrapped with heat-resistant silicone, which is not easy to puncture when it contacts the non-woven fabric. The second end of the separation rod 43 is provided with a sliding ball 432 that fits the surface of the fixed cam shaft 41. The sliding ball 432 and the rotating sleeve 42 are provided with a first elastic plate 433. The first elastic plate 433 can make the separation rod 43 fit the surface of the fixed cam shaft 41 when sliding along the rotating sleeve 42; when in use, the rotating The sleeve 42 is driven to rotate so that the sliding ball 432 slides along the surface of the fixed cam shaft 41, and at the same time drives the separation rod 43 to extend along the rotating sleeve 42 to make the toggle sharp corner 431 fit the surface of the printing roller 1, and as the rotating sleeve 42 continues to rotate, the toggle sharp corner 431 is made to slide along the surface of the printing roller 1, and the non-woven fabric hardened on the surface of the printing roller 1 is peeled off, and then the toggle sharp corner 431 is retracted to push the separated non-woven fabric back to its position, which can peel off the non-woven fabric that has cooled and hardened on the surface of the printing roller 1, so as to avoid the non-woven fabric from adhering to the surface of the printing roller 1 for a long time and hindering the next hot rolling.

[0042] In the above technical solution, when the two printing rollers 1 rotate and hot-roll out the non-woven fabric, the rotating sleeve 42 is also driven to rotate. At this time, the separation rod 43 will extend along the fixed camshaft 41 as the rotating sleeve 42 rotates, and the toggle sharp corner 431 will fit the surface of the printing roller 1. As the rotating sleeve 42 continues to rotate, the toggle sharp corner 431 will pass along the surface of the printing roller 1, so that the non-woven fabric on the surface of the printing roller 1 due to cooling and hardening is separated from the printing roller 1 and fits the toggle sharp corner 431. Then the rotating sleeve 42 continues to rotate to retract the separation rod 43, so as to push the separated non-woven fabric back to its position by the toggle sharp corner 431, and the non-woven fabric cooled and hardened on the surface of the printing roller 1 can be peeled off to avoid the non-woven fabric from adhering to the surface of the printing roller 1 for a long time and hindering the next hot rolling.

[0043] Furthermore, the structure that drives the rotating sleeve 42 to rotate can be a motor, and the output end of the motor is connected to the rotating sleeve 42 through a coupling; it can also be a belt arranged between the printing roller 1 and the rotating sleeve 42, and the rotation of the printing roller 1 drives the rotating sleeve 42 to rotate; or it can be any driving structure known to those skilled in the art.

[0044] As a further embodiment provided by the present invention, it also includes an air cooling mechanism 3, which includes a blowing shell 31. A rotating shaft 33 is rotatably connected inside the blowing shell 31, and a driving fan blade 32 is provided on the rotating shaft 33. A transmission belt is provided between the rotating shaft 33 and the rotating sleeve 42. The driving fan blade 32 rotates with the airflow to drive the rotating shaft 33 to drive the toggle tip 431 to rotate.

[0045] Specifically, the air cooling mechanism 3 includes a blowing shell 31, a rotating shaft 33 is rotatably connected in the blowing shell 31, and a driving fan blade 32 is provided on the rotating shaft 33. When the air flow passes through the blowing shell 31, the air flow drives the driving fan blade 32 to rotate, thereby driving the rotating shaft 33 to rotate. A first gear 331 is provided on the rotating shaft 33, and a second gear 332 meshing with the first gear 331 is provided on the blowing shell 31. A transmission belt is provided between the second gear 332 and the rotating sleeve 42, and a blowing port 311 is opened on the blowing shell 31, and the blowing port 311 faces the printing roller 1; when in use, the air flow passes through the blowing shell 31, which drives the driving fan blade 32 to rotate to drive the rotating shaft 33 The driving shaft 33 rotates, and the second gear 332 engaged with the first gear 331 drives the rotating sleeve 42 to rotate, so that the sliding ball 432 slides along the surface of the fixed cam shaft 41, and at the same time drives the separation rod 43 to extend along the rotating sleeve 42 to make the toggle point 431 fit the surface of the printing roller 1, and as the rotating sleeve 42 continues to rotate, the toggle point 431 is made to slide along the surface of the printing roller 1, and the non-woven fabric hardened on the surface of the printing roller 1 is peeled off, and then the toggle point 431 is retracted to push the separated non-woven fabric back to its position, which can peel off the non-woven fabric that has cooled and hardened on the surface of the printing roller 1, so as to avoid the non-woven fabric from adhering to the surface of the printing roller 1 for a long time and hindering the next hot rolling.

[0046] As a further embodiment provided by the present invention, the driving blades 32 are rotatably connected to the rotating shaft 33 in a linear array, and the driving blades 32 include the following two states:

[0047] First state: the driving blades 32 drive the rotating shaft 33 to rotate together;

[0048] Second state: the driving blades 32 and the rotating shaft 33 rotate separately.

[0049] Specifically, a plurality of driving blades 32 are connected to the rotating shaft 33 in a linear array. The driving blades 32 will have the following two states depending on the speed difference between the driving blades 32 and the rotating shaft 33:

[0050] First state: The speed of the driving blades 32 exceeds that of the rotating shaft 33. At this time, the driving blades 32 drive the rotating shaft 33 to rotate together;

[0051] The second state: the rotation speed of the driving blades 32 is lower than that of the rotating shaft 33. At this time, the driving blades 32 will not drive the rotating shaft 33 to rotate, and the driving blades 32 will not be rotated by the rotating shaft 33 (that is, it will not affect the normal rotation of the rotating shaft 33); when in use, the air flow passes through the blowing shell 31, which will drive the driving blades 32 to rotate to drive the rotating shaft 33 to rotate. At this time, the second gear 332 engaged with the first gear 331 drives the rotating sleeve 42 to rotate. When different driving blades 32 have different flow rates in different areas, the driving blades 32 with a faster rotation speed will drive the rotating shaft 33 to rotate together, while the driving blades 32 with a lower rotation speed than the rotating shaft 33 will not drive the rotating shaft 33 to rotate. When the fan blades 32 are driven, they will not be rotated by the rotating shaft 33 (that is, they will not affect the normal rotation of the rotating shaft 33). The rotation of the rotating sleeve 42 drives the sliding ball 432 to slide along the surface of the fixed cam shaft 41, and at the same time drives the separation rod 43 to extend along the rotating sleeve 42 to make the toggle point 431 fit the surface of the printing roller 1, and as the rotating sleeve 42 continues to rotate, the toggle point 431 is made to slide along the surface of the printing roller 1 to peel off the non-woven fabric hardened on the surface of the printing roller 1, and then the toggle point 431 is retracted to push the separated non-woven fabric back to its original position, which can peel off the non-woven fabric that has cooled and hardened on the surface of the printing roller 1, so as to avoid the non-woven fabric from adhering to the surface of the printing roller 1 for a long time and hindering the next hot rolling.

[0052] As the optimal embodiment provided by the present invention, a dial plate 324 is provided in the driving fan blade 32, and a one-way rotating plate 34 and a limiting plate 342 are rotatably connected to the rotating shaft 33. The dial plate 324 is driven to fit the one-way rotating plate 34 and flip to fit or move away from the limiting plate 342.

[0053] When the cam 33 is in the unlock state, the cam 33 is locked and the locking plate 342 is unlocked, so the cam 33 is locked. The driving shaft 33 rotates together, and the driving fan blade 32 rotates at a speed lower than that of the rotating shaft 33, so that the one-way rotating plate 34 will flip along the dial plate 324. At this time, the rotating shaft 33 will not be driven to rotate, and the driving fan blade 32 will not be rotated by the rotating shaft 33 (that is, it will not affect the normal rotation of the rotating shaft 33). The rotation of the rotating sleeve 42 drives the sliding ball 432 to slide along the surface of the fixed cam shaft 41, and at the same time drives the separation rod 43 to extend along the rotating sleeve 42 to make the toggle point 431 fit the surface of the printing roller 1, and as the rotating sleeve 42 continues to rotate, the toggle point 431 is made to slide along the surface of the printing roller 1, and the non-woven fabric hardened on the surface of the printing roller 1 is peeled off, and then the toggle point 431 is retracted to push the separated non-woven fabric back to its position, which can peel off the non-woven fabric that has cooled and hardened on the surface of the printing roller 1, so as to avoid the non-woven fabric from adhering to the surface of the printing roller 1 for a long time and hindering the next hot rolling.

[0054] As a further embodiment provided by the present invention, a temperature sensor 44 is provided on the toggle corner 431, and a wind control component 5 is provided on the blowing housing 31. The temperature sensor 44 is electrically connected to the wind control component 5. The wind control component 5 is used to adjust the speed of the driving blades 32. The driving blades 32 include elastic blades arranged in a circular array. The elastic blades include the following two states:

[0055] First state: multiple elastic blades are fitted together and folded;

[0056] Second state: the multiple elastic blades are opened and attached to the inner wall of the blowing shell 31 .

[0057] Specifically, a temperature sensor 44 is provided on the toggle corner 431, and the temperature sensor 44 is used to detect the local temperature of the printing roller 1. A wind control component 5 is provided on the blowing shell 31, and the temperature sensor 44 is electrically connected to the wind control component 5. The driving blades 32 include elastic blades arranged in a circumferential array. The wind control component 5 is used to deform the elastic blades to adjust the speed of the driving blades 32. When the elastic blades are deformed, they include the following two states:

[0058] In the first state, the multiple elastic blades are fitted together and folded so that the driving blades 32 do not touch the inner wall of the blowing housing 31 during rotation, ensuring the normal rotation of the driving blades 32. At this time, the rotation speed is controlled by the air flow speed.

[0059] Second state: the multiple elastic blades are opened and attached to the inner wall of the blowing shell 31. At this time, the airflow pushing the driving blades 32 to rotate is hindered by the inner wall of the blowing shell 31, so that the driving blades 32 rotate slowly or do not rotate;

[0060] When in use, the air flow passes through the blowing shell 31, driving the driving blades 32 to rotate and drive the rotating shaft 33 to rotate. At this time, the second gear 332 engaged with the first gear 331 drives the rotating sleeve 42 to rotate. When different driving blades 32 have different flow rates in different areas, the driving blades 32 with a faster rotation speed will push the dial plate 324 against the one-way rotating plate 34 to flip toward the limit plate 342, thereby driving the rotating shaft 33 to rotate together. The driving blades 32 have a lower rotation speed than the rotating shaft 33, so that the one-way rotating plate 34 will flip along the dial plate 324, and will not drive the rotating shaft 33 to rotate. At this time, the driving blades 32 will not be driven by the rotating shaft 33 The rotating sleeve 42 rotates (that is, it will not affect the normal rotation of the rotating shaft 33), and the rotation of the rotating sleeve 42 drives the sliding ball 432 to slide along the surface of the fixed cam shaft 41, and at the same time drives the separation rod 43 to extend along the rotating sleeve 42 to make the sharp corner 431 fit the surface of the printing roller 1, and as the rotating sleeve 42 continues to rotate, the sharp corner 431 is made to slide along the surface of the printing roller 1 to peel off the non-woven fabric hardened on the surface of the printing roller 1, and then the sharp corner 431 is retracted to push the separated non-woven fabric back to its position, which can peel off the non-woven fabric that has cooled and hardened on the surface of the printing roller 1, so as to avoid the non-woven fabric from adhering to the surface of the printing roller 1 for a long time and hindering the next hot rolling. When the pointed corner 431 is moved close to the printing roller 1, the temperature sensor 44 will detect the temperature of the printing roller 1. When the temperature of the printing roller 1 is excessively reduced by the air cooling mechanism 3, the wind control component 5 will open the elastic blades to fit the inner wall of the blowing shell 31. At this time, the airflow drives the driving blades 32 to rotate, but is hindered by the inner wall of the blowing shell 31, so that the driving blades 32 rotate slowly or do not rotate, so as to increase the temperature of the printing roller 1. When the temperature of the printing roller 1 is too high, the wind control component 5 will fit the multiple elastic blades together to make the driving blades 32 not contact the inner wall of the blowing shell 31 when rotating, so as to ensure the normal rotation of the driving blades 32. At this time, the rotation speed is controlled by the airflow speed to cool the printing roller 1.

[0061] As the optimal embodiment provided by the present invention, a hollow portion is provided on the elastic blade, and a negative pressure adsorption port 321 and a suction opening 322 are respectively provided on the elastic blade. The air flow is driven to flow along the suction opening 322 to drive the negative pressure adsorption port 321 on the elastic blade to be adsorbed on the side wall of an adjacent elastic blade.

[0062] When the airflow is in the air-conditioning state, the air flow is in the air-conditioning state, and the suction pipe 322 is fixed on the upper surface of the air-conditioning base 32 so as to prevent the air from leaking out of the air-conditioning base 32. When the airflow is in the air-conditioning state, the suction pipe 322 is fixed on the upper surface of the air-conditioning base 32 so as to prevent the air from leaking out of the air-conditioning base 32. The cam 33 is rotated by the rotating shaft 33, and the driving blade 32 is not driven by the rotating shaft 33. The rotation of the driving blade 32 is not caused by the rotating shaft 33 (i.e., it does not affect the normal rotation of the rotating shaft 33). The rotation of the rotating sleeve 42 drives the sliding ball 432 to slide along the surface of the fixed cam shaft 41, and at the same time drives the separating rod 43 to extend along the rotating sleeve 42 to make the toggle point 431 fit the surface of the printing roller 1. As the rotating sleeve 42 continues to rotate, the toggle point 431 is moved along the surface of the printing roller 1 to peel off the non-woven fabric hardened on the surface of the printing roller 1. Then, the toggle point 431 is retracted to push the separated non-woven fabric back to its original position, so as to peel off the non-woven fabric cooled and hardened on the surface of the printing roller 1, so as to prevent the non-woven fabric from adhering to the surface of the printing roller 1 for a long time and hindering the next hot rolling. When the sharp corner 431 is moved close to the printing roller 1, the temperature sensor 44 will detect the temperature of the printing roller 1. When the temperature of the printing roller 1 is excessively reduced by the air cooling mechanism 3, the wind control component 5 separates the negative pressure adsorption port 321 of one elastic blade from the adsorption protrusion 323 of the adjacent elastic blade. At this time, the elastic blade opens and fits the inner wall of the blowing shell 31, so that the airflow drives the driving blade 32 to rotate, which is hindered by the inner wall of the blowing shell 31, causing the driving blade 32 to rotate slowly or not rotate, thereby increasing the temperature of the printing roller 1. When the printing roller 1 is cooled, the temperature of the printing roller 1 is increased ... 1 is too high, the wind control component 5 will fit the negative pressure adsorption port 321 to the adsorption protrusion 323 of an adjacent elastic blade. At this time, the air flow will flow along the suction opening 322 and take away part of the gas in the suction opening 322, so that the hollow part becomes a negative pressure space, so that the negative pressure adsorption port 321 continues to adsorb the adsorption protrusion 323 due to the negative pressure space; so that the driving fan blade 32 will not contact the inner wall of the blowing shell 31 when rotating, ensuring the normal rotation of the driving fan blade 32. At this time, the rotation speed is controlled by the air flow speed to cool the printing roller 1.

[0063] As an embodiment further provided by the present invention, the wind control component 5 includes a sliding shell 51 fixedly connected to the blowing shell 31 and a sealing plate 54 on the sliding shell 51. The sliding shell 51 is slidably connected with a folding column 55, and the folding column 55 is driven to approach the driving blades 32 to fold the driving blades 32. The sliding shell 51 is fixedly connected with an air supply pipe 6, and the sealing plate 54 is driven to slide along the sliding shell 51 to seal the sliding shell 51 and the blowing shell 31.

[0064] Specifically, the wind control component 5 includes a sliding shell 51 and a sliding block 53 fixedly connected to the blowing shell 31. The sliding shell 51 is fixedly connected to the fixing plate 52. The fixing plate 52 is symmetrically provided with a guide sleeve 520. The two guide sleeves 520 are respectively provided with a guide channel 521 and a guide slope 522 in a circumferential array. The guide channels 521 and the guide slopes 522 on the two guide sleeves 520 are staggered. The sliding block 53 is symmetrically provided with a first sliding column 531. The first sliding column 531 is provided with a toggle block 532 in a circumferential array. The toggle block 532 is slidably connected to On the guide channel 521, the first sliding column 531 is rotatably connected to the rotating column 50, and the rotating column 50 is provided with a circumferential array of guiding inclined columns 501. The blocking plate 54 and the retracting column 55 are respectively rotatably connected to the two rotating columns 50, and the blocking plate 54 and the retracting column 55 are both provided with a spring fixedly connected to the fixed plate 52. The air supply pipe 6 transports the airflow to the sliding shell 51, and then transports it to the blowing shell 31 through the sliding shell 51. The sliding block 53 is fixedly connected to the output end of the cylinder. When the blocking plate 54 and the retracting column 55 are extended or retracted at the output end of the cylinder, they have the following three states:

[0065] First state: The cylinder output end extends to make the toggle block 532 slide along the guide channel 521, so that the blocking plate 54 and the retracting column 55 are both pushed out. At this time, the blocking plate 54 blocks the sliding housing 51 and the blowing housing 31, and the retracting column 55 is in contact with the driving blade 32.

[0066] Second state: The cylinder output end retracts, and the force pushing against the sliding block 53 is lost. Then, the spring pulls the blocking plate 54 and the retracting post 55 toward the fixed plate 52. At this time, the guiding inclined post 501 on the blocking plate 54 slides into the guiding inclined surface 522 to continuously block the sliding housing 51 and the blowing housing 31, while the guiding inclined post 501 on the retracting post 55 slides into the guiding channel 521 to move away from the driving blades 32.

[0067] The third state: the output end of the cylinder retracts, and the force to push the sliding block 53 is lost. Then the spring pulls the blocking plate 54 and the folding column 55 close to the fixed plate 52. At this time, the guiding inclined column 501 on the blocking plate 54 slides into the guide channel 521 to lose the ability to block the sliding shell 51 and the blowing shell 31, and the guiding inclined column 501 on the folding column 55 slides into the guiding inclined surface 522 to always fit the driving blades 32.

[0068] When in use, the air flow passes through the blowing shell 31, driving the driving blades 32 to rotate and drive the rotating shaft 33 to rotate. At this time, the second gear 332 engaged with the first gear 331 drives the rotating sleeve 42 to rotate. When different driving blades 32 have different flow rates in different areas, the driving blades 32 with a faster rotation speed will push the dial plate 324 against the one-way rotating plate 34 to flip toward the limit plate 342, thereby driving the rotating shaft 33 to rotate together. The driving blades 32 have a lower rotation speed than the rotating shaft 33, so that the one-way rotating plate 34 will flip along the dial plate 324, and will not drive the rotating shaft 33 to rotate. At this time, the driving blades 32 will not be driven by the rotating shaft 33 The rotating sleeve 42 rotates (that is, it will not affect the normal rotation of the rotating shaft 33), and the rotation of the rotating sleeve 42 drives the sliding ball 432 to slide along the surface of the fixed cam shaft 41, and at the same time drives the separation rod 43 to extend along the rotating sleeve 42 to make the sharp corner 431 fit the surface of the printing roller 1, and as the rotating sleeve 42 continues to rotate, the sharp corner 431 is made to slide along the surface of the printing roller 1 to peel off the non-woven fabric hardened on the surface of the printing roller 1, and then the sharp corner 431 is retracted to push the separated non-woven fabric back to its position, which can peel off the non-woven fabric that has cooled and hardened on the surface of the printing roller 1, so as to avoid the non-woven fabric from adhering to the surface of the printing roller 1 for a long time and hindering the next hot rolling.When the temperature of the printing roller 1 is excessively decreased by the air cooling mechanism 3, the air cylinder is driven to extend to make the sliding block 532 slide along the guide channel 521, so that the blocking plate 54 and the folding column 55 are pushed out. At this time, the blocking plate 54 blocks the sliding shell 51 and the air blowing shell 31, and the folding column 55 is attached to the driving fan blade 32. Then the output end of the air cylinder is retracted, and the spring pulls the blocking plate 54 and the folding column 55 close to the fixed plate 52. At this time, the guide inclined column 501 on the blocking plate 54 slides into the guide inclined surface 522 to continuously block the sliding shell 51 and the air blowing shell 31, and the guide inclined column 501 on the folding column 55 slides into the guide channel 521 to be away from the driving fan blade 32, so that part of the airflow is retained in the sliding shell 51 to reduce the airflow blowing to the driving fan blade 32, resulting in a decrease in the negative pressure of the hollow part. At this time, one of the elastic blades is opened due to the elastic opening, so that the negative pressure suction port 321 and the suction protrusion 323 of the adjacent elastic blade are separated. At this time, the elastic blade is opened and attached to the inner wall of the air blowing shell 31, so that when the airflow drives the driving fan blade 32 to rotate, it is hindered by the inner wall of the air blowing shell 31, so that the driving fan blade 32 is slowly rotated or not rotated, so as to increase the temperature of the printing roller 1. When the temperature of the printing roller 1 is too high, the air cylinder is retracted again, so that the guide inclined column 501 on the blocking plate 54 slides into the guide channel 521 to lose the ability to block the sliding shell 51 and the air blowing shell 31, and the guide inclined column 501 on the folding column 55 slides into the guide inclined surface 522 to always attach to the driving fan blade 32. At this time, the negative pressure suction port 321 is attached to the suction protrusion 323 of the adjacent elastic blade, so that the airflow flows along the suction opening 322 and carries away part of the gas in the suction opening 322, so that the hollow part becomes a negative pressure space, so that the negative pressure suction port 321 continuously adsorbs the suction protrusion 323 due to the negative pressure space; so that the driving fan blade 32 does not contact the inner wall of the air blowing shell 31 when rotating, ensuring the normal rotation of the driving fan blade 32. At this time, the speed is controlled by the airflow speed to cool the printing roller 1.

[0069] As the optimal embodiment provided by the application, the fixed camshaft 41 is provided with the extension contour 411 and the retraction contour 412.

[0070] Specifically, there is a stagnation profile between the extending profile 411 and the retracting profile 412, and the cross-section of the stagnation profile is a regular arc, and the sliding ball 432 will fit the extending profile 411, the retracting profile 412, and the stagnation profile as it rotates; when in use, the air flow passes through the blowing shell 31, which will drive the driving blades 32 to rotate to drive the rotating shaft 33 to rotate. At this time, the second gear 332 engaged with the first gear 331 drives the rotating sleeve 42 to rotate. When different driving blades 32 have different flow rates in different areas, the driving blades 32 with a faster rotation speed will push the dial plate 324 against the one-way rotating plate 34 to flip toward the limit plate 342, so as to drive the rotating shaft 33 to rotate together, and the driving blades 32 have a lower rotation speed than the rotating shaft 33, so that the one-way rotating plate 34 will flip along the dial plate 324, and will not drive the rotating shaft 33 to rotate. At the same time, the driving fan blades 32 will not be rotated by the rotating shaft 33 (that is, it will not affect the normal rotation of the rotating shaft 33). The rotation of the rotating sleeve 42 drives the sliding ball 432 to slide along the surface of the extended profile 411, and at the same time drives the separation rod 43 to extend along the rotating sleeve 42 to make the toggle sharp corner 431 fit the surface of the printing roller 1, and as the rotating sleeve 42 continues to rotate, the sliding ball 432 slides along the surface of the stagnant profile to make the toggle sharp corner 431 pass along the surface of the printing roller 1, and the non-woven fabric hardened on the surface of the printing roller 1 is peeled off, and then the sliding ball 432 slides along the surface of the retraction profile 412 to make the toggle sharp corner 431 retract to push the separated non-woven fabric back to its position, which can peel off the non-woven fabric that has cooled and hardened on the surface of the printing roller 1, so as to avoid the non-woven fabric from adhering to the surface of the printing roller 1 for a long time and hindering the next hot rolling.When the pointed corner 431 is moved close to the printing roller 1, the temperature probe 44 will detect the temperature of the printing roller 1. When the temperature of the printing roller 1 is excessively reduced by the air cooling mechanism 3, the cylinder is driven to extend to make the toggle block 532 slide along the guide channel 521, so that the blocking plate 54 and the retracting column 55 are both pushed out. At this time, the blocking plate 54 blocks the sliding shell 51 and the blowing shell 31, and the retracting column 55 fits the driving fan blade 32, and then the cylinder output end retracts. At this time, the force of pushing the sliding block 53 is lost, and then the spring pulls the blocking plate 54 and the retracting column 55 close to the fixed The fixed plate 52, at this time, the guiding inclined column 501 on the blocking plate 54 slides into the guiding inclined surface 522 to continuously block the sliding shell 51 and the blowing shell 31, and the guiding inclined column 501 on the retracting column 55 slides into the guiding channel 521 to stay away from the driving fan blade 32, so that part of the air flow is retained in the sliding shell 51, so as to reduce the air flow blowing to the driving fan blade 32, resulting in a decrease in the negative pressure of the hollow part. At this time, one of the elastic blades is elastically opened, so that the negative pressure adsorption port 321 and the adsorption protrusion 323 of the adjacent elastic blade are separated. At this time, the elastic blades are opened and fit against the inner wall of the blowing shell 31, so that the airflow drives the driving blades 32 to rotate but is blocked by the inner wall of the blowing shell 31, so that the driving blades 32 rotate slowly or do not rotate, so as to increase the temperature of the printing roller 1. When the temperature of the printing roller 1 is too high, the cylinder retracts and contracts again, so that the guiding inclined column 501 on the blocking plate 54 slides into the guiding channel 521, so as to lose the ability to block the sliding shell 51 and the blowing shell 31, and the guiding inclined column 501 on the retracting column 55 slides into the guiding inclined surface 522, so as to increase the temperature of the printing roller 1. It is always in contact with the driving fan blade 32. At this time, the negative pressure adsorption port 321 is in contact with the adsorption protrusion 323 of an adjacent elastic blade. At this time, the air flow will flow along the suction opening 322 and take away part of the gas in the suction opening 322, so that the hollow part becomes a negative pressure space, so that the negative pressure adsorption port 321 continues to adsorb the adsorption protrusion 323 due to the negative pressure space; so that the driving fan blade 32 will not contact the inner wall of the blowing shell 31 during rotation, ensuring the normal rotation of the driving fan blade 32. At this time, the rotation speed is controlled by the air flow speed to cool the printing roller 1.
