At this time, the airflow sprayed from top to bottom can enter this part of the space to achieve the drying effect on the bottom of the product, avoiding the poor bottom drying effect in the traditional product drying process. The setting of the connecting pipe can inhale the airflow through the connecting hole under the action of the first fan, realize the guidance of the airflow, so that the airflow can better pass through the space formed between the bottom of the product and the connecting box, thereby improving the drying effect.

[0018] 3. By setting up an auxiliary structure, the preheated airflow can be guided into the interior of the installation box under the joint action of the second fan and the duct and finally discharged through the nozzle hole. The airflow ejected through the nozzle hole can blow away a large amount of impregnation liquid adhering to the paper, reducing the difficulty of subsequent drying. The blown-off impregnation liquid can fall into the interior of the impregnation box for reuse. At the same time, the pressure of the two adjusting rollers on the paper during the conveying process can be changed by rotating the screw rod to adjust the position of the slider. It can be adjusted according to the actual situation to reduce the situation where the paper breaks due to excessive tension changes. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figure 1-Figure 7 The impregnation and drying integrated equipment for impregnated paper shown in the figure comprises an impregnation box 1, a drying box 2 is arranged on one side of the impregnation box 1, two symmetrically distributed guard plates 102 are fixedly connected to the top of the impregnation box 1, a pressing roller 103 is arranged inside the impregnation box 1, two groups of guide rollers 101 are arranged between the two guard plates 102, an auxiliary structure 4 is arranged on the surface of the impregnation box 1, a drying structure 3 is arranged inside the drying box 2, and a transmission mechanism 5 is arranged inside the drying box 2;

[0030] Among them, the drying structure 3 includes three mounting blocks 302 fixedly connected to the inner top wall of the drying box 2, and two partitions 305 are arranged at the bottom of the three mounting blocks 302. The two partitions 305 separate the inner wall of the drying box 2 and the bottom of the mounting blocks 302 in sequence along the conveying direction of the transmission mechanism 5 to form a preheating zone, a drying zone and a cooling zone.

[0031] like Figure 1-Figure 7As shown, an installation cavity is provided inside the installation block 302, a first fan 304 is arranged inside the installation cavity, a through slot 303 is provided on the top of the installation block 302 located inside the cooling zone, a through slot connected to the through slot 303 is provided on the top of the drying box 2, a filter screen 301 is embedded in the inner wall of the through slot, a heating tube 306 is provided inside the installation block 302 located inside the drying zone, and the heating tube 306 is located inside the installation cavity.

[0032] A groove is formed at the bottom of the mounting block 302, and the inner bottom wall of the mounting cavity is provided with nozzles 307 which are evenly distributed and communicated with the groove.

[0033] By starting the first fan 304, the outside air can be guided to pass through the filter 301, the through groove and the through groove 303 in turn into the interior of the installation cavity, and the gas is discharged through the nozzle 307 connected thereto. The discharged gas acts on the cooling zone to cool the surface of the dried product. The partition 305 is set to reduce the interference of the airflow on the adjacent area.

[0034] The three mounting blocks 302 are internally provided with uniformly distributed conduits 308 , the cross-section of which is an inverted “L” shape, one end of which is connected to the interior of the drying box 2 , and the other end of which is connected to the adjacent mounting cavity.

[0035] The inner wall of the conduit 308 is fixedly connected to a mounting plate 309, the top of the mounting plate 309 is fixedly connected to a connecting rod 312, the surface of the connecting rod 312 is slidably connected to a sealing ring 311, the outer side of the sealing ring 311 is slidably connected to the inner wall of the conduit 308, a through hole 313 is opened in the middle of the surface of the connecting rod 312, and a spring 310 is fixedly connected between the bottom of the sealing ring 311 and the top of the mounting plate 309.

[0036] The setting of the duct 308 can make the air flow from the outside pass through the cooling zone in sequence and then be introduced into the installation cavity inside the drying zone under the action of the first fan 304 inside the three installation blocks 302, and then be sprayed out through the nozzle 307 after the air flow is heated by the heating tube 306. The air flow after drying can be introduced into the interior of the preheating zone under the action of the duct 308 connected to the installation cavity in the preheating zone, and the air flow carrying the residual heat is used to preheat and dry the products in the preheating zone through the nozzle 307. The preheating method is used to improve the use of heat in the drying process and enhance the drying effect. At the same time, it avoids the situation where the impregnation layer on the surface of the product is damaged due to rapid heating and drying, reduces heat loss and improves the utilization rate of heat. In addition, in the process of cooling the product in the cooling zone, part of the residual heat can be carried into the installation cavity provided with the heating tube 306, thereby improving the heating efficiency of the air flow, reducing energy loss and reducing the use cost.

[0037] The mutual cooperation of the sealing ring 311, the connecting rod 312, the through hole 313, the spring 310 and the mounting plate 309 can limit the moving direction of the airflow, so that the airflow can only be introduced into the mounting cavity in one direction through the interior of the drying box 2. Therefore, in the process of the airflow passing through the interior of the drying box 2 and being introduced into the interior of the conduit 308, the sealing ring 311 can be pushed to slide along the surface of the connecting rod 312. In this process, the spring 310 can be compressed until the sealing ring 311 moves to the middle of the connecting rod 312. The airflow can bypass the sealing ring 311 under the action of the through hole 313 and be introduced into the interior of the mounting cavity through the conduit 308. When the airflow flows in the reverse direction, the sealing ring 311 is reset under the action of the spring 310, thereby limiting the reverse flow of the airflow inside the mounting cavity.

[0038] like Figure 1-Figure 7 As shown, the drying structure 3 also includes three guide blocks 314 respectively arranged inside the preheating zone, the drying zone and the cooling zone, a slope 318 is provided on one side of the guide block 314, a connecting box 315 is fixedly connected to the other side of the guide block 314, and evenly distributed connecting holes 316 are provided on the top of the connecting box 315, one side of the connecting box 315 is connected to a connecting pipe 317, and the other end of the connecting pipe 317 is connected to the adjacent installation cavity.

[0039] The setting of the inclined surface 318 can use the inclined surface 318 to shovel up the bottom of the product during the process of conveying the product by the transmission mechanism 5, so that a certain space is formed between the bottom of the product and the connecting box 315. At this time, the airflow sprayed from top to bottom can enter this part of the space to achieve the drying effect on the bottom of the product, avoiding the situation where the bottom drying effect is poor during the traditional product drying process. The setting of the connecting pipe 317 can inhale the airflow through the connecting hole 316 under the action of the first fan 304, realize the guidance of the airflow, so that the airflow can better pass through the space formed between the bottom of the product and the connecting box 315, thereby improving the drying effect.

[0040] like Figure 1-Figure 7 As shown, the auxiliary structure 4 includes a slider 411 slidably connected to the surface of the impregnation box 1, a cavity 412 and a connecting cavity 406 are provided inside the slider 411, a connecting channel 410 is connected between the cavity 412 and the connecting cavity 406, two fixed tubes 409 connected to the connecting cavity 406 are fixedly connected to one side of the slider 411, the other end of the fixed tube 409 passes through the impregnation box 1 and is connected to an adjusting roller 407, and a uniformly distributed spray hole 408 is provided on the surface of the adjusting roller 407.

[0041] The auxiliary structure 4 also includes an installation box 401 fixedly connected to one side of the drying box 2, one side of the installation box 401 is connected to one end of the adjacent conduit 308, a second fan 402 is arranged inside the installation box 401, one end of the installation box 401 is connected to a connecting hose 403, and the other end of the connecting hose 403 is connected to the cavity 412.

[0042] The surface of the dipping box 1 is rotatably connected to a screw rod 404, a slider 411 is threadedly connected to the surface of the screw rod 404, two symmetrically distributed guide rods 405 are fixedly connected to the surface of the dipping box 1, and a slide plate slidably connected to the surface of the guide rod 405 is fixedly connected to the surface of the slider 411.

[0043] The airflow after preheating can be introduced into the interior of the installation box 401 under the joint action of the second fan 402 and the duct 308 and discharged through the connecting hose 403. The airflow discharged through the connecting hose 403 can be introduced into the interior of the cavity 412 and into the interior of the connecting cavity 406 under the action of the connecting channel 410, and then can be introduced into the interior of the adjusting roller 407 under the action of the fixing tube 409, so that the airflow can be discharged through the spray hole 408.

[0044] The paper to be impregnated is introduced into the drying box 2 by passing through one of the guide rollers 101, the pressure roller 103 and the other guide roller 101 in turn. During this process, the paper is approximately V-shaped, and under the action of the guide roller 101, it can be fully in contact with the impregnation liquid inside the impregnation box 1, and the impregnated paper can pass between the two adjusting rollers 407. At this time, the airflow sprayed through the nozzle 408 can blow away a large amount of impregnation liquid adhering to the paper, reducing the difficulty of subsequent drying. The blown-off impregnation liquid can fall into the impregnation box 1 for reuse. At the same time, the position of the slider 411 can be adjusted by rotating the screw rod 404 to change the pressure of the two adjusting rollers 407 on the paper during transportation, and can be adjusted according to actual conditions to reduce the situation where the tension changes too much and causes paper breakage.

[0045] Working principle: the paper to be impregnated is introduced into the drying box 2 by bypassing one set of guide rollers 101, the pressure roller 103 and the other set of guide rollers 101 in turn. In this process, the paper is approximately V-shaped and passes through two adjusting rollers 407. The paper entering the drying box 2 can pass through the preheating zone, the drying zone and the cooling zone in turn under the action of the transmission mechanism 5. The airflow can be guided by setting the drying structure 3. In this process, the preheating zone uses the residual heat in the airflow after drying in the drying zone for preheating operation, and the airflow can carry part of the residual heat to enter the installation cavity provided with the heating pipe 306 when the cooling zone cools the product, thereby improving the heating efficiency of the airflow, reducing energy loss and reducing the use cost. The preheated airflow is combined with the second fan 402 and the duct 308 to It is introduced into the interior of the installation box 401 and discharged through the connecting hose 403. The airflow discharged through the connecting hose 403 can be introduced into the interior of the cavity 412 and introduced into the interior of the connecting cavity 406 under the action of the connecting channel 410, so that it can be introduced into the interior of the adjusting roller 407 under the action of the fixed tube 409, so that the airflow can be discharged through the spray hole 408. The airflow sprayed through the spray hole 408 can blow away a large amount of impregnation liquid adhering to the paper, reducing the difficulty of subsequent drying. The blown-off impregnation liquid can fall into the interior of the impregnation box 1 for reuse. At the same time, the position of the slider 411 can be adjusted by rotating the screw rod 404 to change the pressure of the two adjusting rollers 407 on the paper during the transportation process, and it can be adjusted according to the actual situation to reduce the situation where the tension changes too much and causes the paper to break.
