[0036] In summary, the technical effects and advantages of the present invention are as follows:

[0037] 1. In the present invention, the composite material is guided to move in the drying box by vertically arranged multi-layer guide rollers, the moving path of the composite fabric in the drying box is increased, the drying time of the composite fabric in the drying box is increased, the drying effect of the composite fabric is better, the drying power consumption is reduced, the length of the drying box is reduced, the floor space of the drying box is reduced, and the economy is improved;

[0038] 2. In the present invention, the heated air is discharged through the drying holes on the guide roller. As the composite fabric moves on the guide roller, the discharged heated air can quickly contact the composite fabric. The drying holes on the guide roller rotate continuously, and the direction of the heated air discharge is constantly changed, so that the hot air in the drying box is more evenly distributed, the drying time of the composite fabric is accelerated, and the energy efficiency is improved.

[0039] 3. In the present invention, the heating air sprayed toward the contact portion between the composite material and the guide roller is blocked in the guide roller by the blocking unit, so as to prevent the heating air from being directly sprayed toward the composite material at a close distance, prevent the heat-sensitive composite material from being overheated and failing, and improve the drying effect;

[0040] 4. In the present invention, the same-direction blocking shell and the reverse blocking shell in the blocking unit move in opposite directions and expand, thereby increasing the blocking range of the hot air discharged from the guide roller, so that different wrap angles of the composite material and the guide roller can be blocked. The same-direction blocking shell and the reverse blocking shell can rotate in the same direction, changing the positions of the same-direction blocking shell and the reverse blocking shell, thereby adapting to different contact parts between the composite material and the guide roller and improving adaptability.

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] Example 1: Reference Figure 1-Figure 10 A multi-layer drying system for thermal paper processing shown in the figure comprises a drying box 1, in which a plurality of drying modules are vertically arranged, the drying modules comprise a plurality of drying components 2 and a heating air component 3, the drying component 2 comprises a guide roller 21 and a blocking unit 22, a plurality of drying holes are formed on the guide roller 21, and the heating air component 3 can discharge the heated air through the drying holes;

[0057] The blocking unit 22 includes a same-direction blocking shell 221, a reverse blocking shell 222, a support shaft 223 and an operating shaft 224. The same-direction blocking shell 221 is sleeved on the reverse blocking shell 222. The guide roller 21 is fixedly connected to the support shaft 223 and is coaxial with the support shaft 223. When the support shaft 223 rotates, it can drive the operating shaft 224 to rotate around the support shaft 223. The same-direction blocking shell 221 and the reverse blocking shell 222 are both rotatably connected to the support shaft 223. When the operating shaft 224 rotates, it can drive the same-direction blocking shell 221 and the reverse blocking shell 222 to rotate in opposite directions.

[0058] The drying assembly 2 further includes a locking unit 23, the locking unit 23 includes a locking plate 231, and the locking plate 231 can be moved to switch between a locking state, an operating state, and an adjustment state;

[0059] In the locked state, the locking plate 231 can lock the support shaft 223 and the operating shaft 224;

[0060] In the operating state, both the support shaft 223 and the operating shaft 224 are able to rotate;

[0061] In the adjustment state, the locking plate 231 locks the operating shaft 224 .

[0062] The composite material is introduced into the drying box 1 and passes through a plurality of guide rollers 21 in sequence. The heated air component 3 introduces the heated air into the guide roller 21. The heated air is discharged through the drying holes on the guide roller 21 to dry the composite material near the guide roller 21. The same-direction blocking shell 221 and the reverse blocking shell 222 are located in the guide roller 21 and abut against the guide roller 21. The guide roller 21 rotates on the same-direction blocking shell 221 and the reverse blocking shell 222. The same-direction blocking shell 221 and the reverse blocking shell 222 block the drying holes of the guide roller 21 toward the composite material, so that the heated air in the guide roller 21 will not be sprayed toward the contact part between the composite material and the guide roller 21. When the wrap angles between different guide rollers 21 and the composite material are different, the locking plate 231 is moved to the operating state, and the operating shaft 224 is rotated. The operating shaft 224 drives the same-direction blocking shell 221 to rotate in the same direction. The operating shaft 224 also drives the reverse blocking shell 222 to rotate in the same direction. On the contrary, the same-direction blocking shell 221 and the reverse blocking shell 222 are moved in opposite directions and expanded, thereby increasing the blocking range and adapting to the different wrap angles of the composite material and the guide roller 21. When the contact positions of the guide roller 21 and the composite material are different, the locking plate 231 is moved to the adjustment state, the operating shaft 224 is locked, and the support shaft 223 is rotated. The support shaft 223 drives the operating shaft 224 to rotate around the support shaft 223. The operating shaft 224 cannot rotate on itself, thereby driving the same-direction blocking shell 221 and the reverse blocking shell 222 to rotate in the same direction, changing the positions of the same-direction blocking shell 221 and the reverse blocking shell 222 in the guide roller 21, and changing the blocking direction to correspond to the contact position between the guide roller 21 and the composite material. When the guide roller 21 rotates to dry the composite material, the locking plate 231 is moved to the locking state, and the support shaft 223 and the operating shaft 224 are locked, so that the blocking direction and blocking range of the same-direction blocking shell 221 and the reverse blocking shell 222 will not change.

[0063] The composite material is guided to move in the drying box 1 by the guide rollers 21 arranged vertically in multiple layers, thereby increasing the moving path of the composite fabric in the drying box 1 and increasing the drying time of the composite fabric in the drying box 1, thereby achieving a better drying effect on the composite fabric, reducing the drying power consumption, reducing the length of the drying box 1, reducing the floor space occupied by the drying box 1, and improving the economy.

[0064] The heated air is discharged through the drying holes on the guide roller 21. As the composite fabric moves on the guide roller 21, the discharged heated air can quickly contact the composite fabric. The drying holes on the guide roller 21 rotate continuously, and the direction in which the heated air is discharged is constantly changed, so that the hot air in the drying box 1 is more evenly distributed, thereby accelerating the drying time of the composite fabric and improving energy efficiency.

[0065] The heating air sprayed toward the contact portion of the composite material and the guide roller 21 is blocked in the guide roller 21 by the blocking unit 22, so as to prevent the heated air from being directly sprayed toward the composite material at a close distance, prevent the heat-sensitive composite material from being overheated and failing, and improve the drying effect.

[0066] The same-direction blocking shell 221 and the reverse blocking shell 222 in the blocking unit 22 move in opposite directions and expand, increasing the blocking range of the hot air discharged from the guide roller 21, so that different wrap angles of the composite material and the guide roller 21 can be blocked. The same-direction blocking shell 221 and the reverse blocking shell 222 can rotate in the same direction, changing the positions of the same-direction blocking shell 221 and the reverse blocking shell 222, thereby adapting to different contact parts between the composite material and the guide roller 21 and improving adaptability.

[0067] At the corners of the composite material, the wrap angle between the composite material and the corresponding guide roller 21 increases and the different wrap angles have different contact positions with the guide roller 21. By adjusting the blocking range and the blocking position, it is possible to adapt to the different wrap angles and contact positions between the composite material and the guide roller 21, so that the contact position with the guide roller 21 will not be overheated by the heated air directly ejected from the corresponding guide roller 21.

[0069] When the locking plate 231 is in the locked state, the supporting locking block 232 abuts against the supporting fixing block 233 .

[0070] When the locking plate 231 is in a locked state, the support locking block 232 and the support fixing block 233 abut against each other, the support locking protrusion and the support fixing protrusion engage with each other, the support fixing block 233 cannot rotate, and thus the support shaft 223 cannot rotate.

[0071] Example 3, reference Figure 1-Figure 10 , which is different from the above embodiment, the locking unit 23 further includes an operation locking block 234 and an operation fixing block 235, the operation fixing block 235 is fixedly mounted on the operation shaft 224, the operation locking block 234 is fixedly mounted on a side of the locking plate 231 close to the operation fixing block 235, an operation locking protrusion is fixed on the operation locking block 234, and an operation fixing protrusion is fixed on the operation fixing block 235;

[0072] When the locking plate 231 is in the locked state, the operation locking block 234 abuts against the operation fixing block 235 .

[0073] When the locking plate 231 is in a locked state, the operation locking block 234 and the operation fixing block 235 abut against each other, the operation locking protrusion and the operation fixing protrusion engage with each other, the operation fixing block 235 cannot rotate, and thus the operation shaft 224 cannot rotate.

[0074] Example 4, reference Figure 1-Figure 10 , which is different from the above embodiment, the locking unit 23 further includes a connecting and fixing ring 236 and a connecting and locking block 237, the connecting and fixing ring 236 is fixedly mounted on the side wall of the drying box 1, the connecting and locking block 237 is fixedly mounted on a side of the locking plate 231 close to the connecting and fixing ring 236, the connecting and fixing ring 236 is fixed with a connecting and fixing protrusion, and the connecting and locking block 237 is fixed with a connecting and locking protrusion;

[0075] When the locking plate 231 is in the locked state, the connection locking block 237 abuts against the connection fixing ring 236 .

[0076] When the locking plate 231 is in a locked state, the connecting locking protrusion and the connecting fixing protrusion engage with each other, so that the locking plate 231 cannot rotate, and the locking plate 231 locks the supporting fixing block 233 and the operating fixing block 235, so that the supporting shaft 223 and the operating shaft 224 cannot rotate, so that the positions of the same-direction blocking shell 221 and the reverse blocking shell 222 will not change, thereby improving stability.

[0077] Example 5, reference Figure 1-Figure 10 , which is different from the above embodiment, the locking unit 23 further includes an adjusting locking block 238 and an adjusting fixing block 239, the adjusting fixing block 239 is fixedly mounted on the operating shaft 224, the adjusting locking block 238 is fixedly mounted on the locking plate 231 on a side close to the adjusting fixing block 239, the adjusting fixing block 239 is fixed with an adjusting fixing protrusion, and the adjusting locking block 238 is fixed with an adjusting locking protrusion;

[0078] When the locking plate 231 is in the adjustment state, the adjustment locking block 238 abuts against the adjustment fixing block 239;

[0079] The locking plate 231 is sleeved on the operating shaft 224 and the supporting shaft 223 and is slidably matched with the operating shaft 224 and the supporting shaft 223;

[0080] When the locking plate 231 is in the operating state, the locking plate 231 is located between the operating fixing block 235 and the adjusting fixing block 239 .

[0081] The movement of the locking plate 231 drives the support locking block 232, the operation locking block 234 and the connection locking block 237 to move, thereby releasing the lock on the operation shaft 224 and the support shaft 223. At this time, rotating the operation shaft 224 can make the same-direction blocking shell 221 and the reverse blocking shell 222 move in reverse directions, thereby increasing the blocking range.

[0082] After that, the locking plate 231 continues to move, and the adjusting locking block 238 on the locking plate 231 is against the adjusting fixing block 239, and the adjusting locking protrusion is meshed with the adjusting fixing protrusion to lock the adjusting fixing block 239, thereby locking the operating shaft 224. At this time, the support shaft 223 is rotated, and the support shaft 223 drives the operating shaft 224 to rotate around the support shaft 223, so that the same-direction blocking shell 221 and the reverse blocking shell 222 rotate in the same direction to change their positions, and the blocking position is adjusted. The operating shaft 224 will not rotate during the movement, and will not cause the blocking range of the same-direction blocking shell 221 and the reverse blocking shell 222 to change.

[0092] A multi-layer drying method for thermal paper processing, using the above-mentioned multi-layer drying system for thermal paper processing, comprises the following steps:

[0094] The heated air component 3 passes the heated air into the guide roller 21, and the heated air is discharged through the drying holes on the guide roller 21 to dry the composite material near the guide roller 21;

[0095] The same-direction blocking shell 221 and the reverse blocking shell 222 are located in the guide roller 21 and abut against the guide roller 21.

[0096] When the wrap angles between different guide rollers 21 and the composite material are different, the locking plate 231 is moved to the operating state, and the operating shaft 224 is rotated.

The support shaft 223 drives the operating shaft 224 to rotate around the support shaft 223, and the operating shaft 224 cannot rotate by itself, thereby driving the same-direction blocking shell 221 and the reverse blocking shell 222 to rotate in the same direction, changing the positions of the same-direction blocking shell 221 and the reverse blocking shell 222 in the guide roller 21, and changing the blocking direction to correspond to the contact position between the guide roller 21 and the composite material;

[0098] When the guide roller 21 rotates to dry the composite material, the locking plate 231 is moved to a locked state, the support shaft 223 and the operating shaft 224 are locked, so that the blocking direction and blocking range of the same-direction blocking shell 221 and the reverse blocking shell 222 will not change.
