[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0036] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8 A continuous printing drying device includes conveyor line 1 and conveyor line 2 5;

[0037] The upper end of the conveyor line 1 is equipped with a destacking and feeding mechanism 2 for disassembling stacked materials one by one;

[0038] The conveyor belt of the second conveyor line 5 is made of wire mesh.

[0039] The outer casing 6 is fixedly installed on the outside of the second conveyor line 5;

[0040] Multiple sets of drying components 3 for drying materials are fixedly installed inside the outer shell 6; the multiple sets of drying components 3 are arranged on the upper and lower sides of the conveyor line 5.

[0041] The outer casing 6 is equipped with a gas filtration mechanism 4 for extracting and filtering the gas generated during drying from inside the outer casing 6.

[0042] The gas filtration mechanism 4 includes an exhaust nozzle 41, an exhaust pipe 42, a fan 43, and a quick-change filter assembly 44; multiple sets of exhaust nozzles 41 are arranged in the left-right direction, each set of exhaust nozzles 41 contains two exhaust nozzles 41 symmetrically arranged about the upper and lower parts of the conveyor line 5, each set of exhaust nozzles 41 is connected to a fan 43 through the exhaust pipe 42, and the front and rear ends of the exhaust nozzles 41 are fixedly connected to the outer casing 6; multiple fans 43 are fixedly installed at the front end of the outer casing 6; the fans 43 are connected to the quick-change filter assembly 44, and the quick-change filter assembly 44 is connected to the upper left side of the front end of the outer casing 6;

[0043] When using the equipment, the operator turns on conveyor line 1 and conveyor line 2. Conveyor line 1 works in conjunction with the destacking and feeding mechanism 2 to destacking the materials that need to be dried and are about to be sealed, and conveying them one by one to the top of conveyor line 2. Conveyor line 2 carries individual cardboard or paperboard into the outer shell 6. Inside the outer shell 6, the drying component 3 dries the cardboard or paperboard. The dried cardboard or paperboard will be sealed immediately. The gas generated during drying is drawn out by the blower 43 through the exhaust pipe 42 and the exhaust nozzle 41 and sent to the filter block quick-change filter component 44 for filtration. The filtered gas is then discharged from the filter block quick-change filter component 44. The filter block quick-change filter component 44 can filter the gas and also quickly replace the filter block that needs to be replaced.

[0044] This invention can automatically feed hard cardboard or paperboard that is about to be sealed and dried inside the feeding mechanism 2, and can also filter the gas generated during the drying process and quickly replace the filter block.

[0045] The quick-change filter assembly 44 includes a cylinder 441, a base plate 442, an air inlet pipe 443, a filter block baffle 444, a bracket 445, a filter assembly housing 446, a sliding limit block 447, and a sliding limit groove 448. The rear end of the filter assembly housing 446 is fixedly connected to the housing 6, and the lower end of the filter assembly housing 446 is slidably connected to the base plate 442. A sliding limit block 447 is installed on the lower side of the base plate 442 to limit the sliding of the base plate 442. The lower end of plate 442 is fixedly connected to air inlet pipe 443, and the end of air inlet pipe 443 away from base plate 442 is connected to air outlet of fan 43; a sliding limiting groove 448 for limiting the sliding of filter block baffle 444 is provided in the middle of the left end of filter assembly housing 446; the front end of filter block baffle 444 and base plate 442 are both fixedly connected to bracket 445, bracket 445 is fixedly connected to drive end of cylinder 441, and cylinder 441 is fixedly connected to front end of filter assembly housing 446;

[0046] After the operator starts the device, the harmful gases generated during the drying of cardboard or paperboard are drawn into the inlet pipe 443 by the fan 43 through the exhaust pipe 42 and the exhaust nozzle 41. The inlet pipe 443 delivers the harmful gases to the inside of the filter assembly housing 446, where they are filtered by the filter blocks and discharged from the top. Because the harmful gases enter from the bottom of the filter assembly housing 446 and exit from the top, the filter blocks inside the filter assembly housing 446 that need to be replaced are those at the bottom of the housing. These filter blocks are square with tapered ends. The cylinder 441 is activated, which moves the support 445 to the right. The filter block baffle 444 moves to the right and inserts into the gap between the first and second filter blocks below through the conical slit of the filter block. At the same time, the base plate 442 moves to the right to remove the restriction on the bottom filter block, and the bottom filter block falls down. Then, the cylinder 441 is activated again, which moves the filter block baffle 444 and the base plate 442 back to their original positions through the support 445. The filter block baffle 444 removes the restriction on the filter block, and the filter block falls on the base plate 442. At this time, the operator only needs to put in the top filter block to complete the filter block replacement.

[0047] This invention can filter harmful gases generated during drying and allows for quick replacement of the filter blocks.

[0048] The destacking and feeding mechanism 2 includes a feeding component 21 and an adjustable blocking component 22; both the feeding component 21 and the adjustable blocking component 22 are connected to the conveyor line 1, and the feeding component 21 is connected to the adjustable blocking component 22.

[0049] The feeding assembly 21 includes a feeding bin 211, a clearance groove 212, and a pusher block 213. The lower end of the feeding bin 211 is fixedly connected to the housing of the conveyor line 1 on both the front and rear sides. The clearance groove 212 is provided on the left and right sides of the lower middle part of the feeding bin 211. The pusher block 213 is slidably connected to the feeding bin 211 through the clearance groove 212. Multiple pushers 213 are fixedly connected to the outer side of the belt of the conveyor line 1.

[0050] The adjustable baffle assembly 22 includes a baffle 221, a screw 222, a slide groove 223, a handwheel 224, and a baffle bracket 225. The lower end of the baffle bracket 225 is fixedly connected to the housing of conveyor line 1 on both the front and rear sides, and the left end of the baffle bracket 225 is fixedly connected to the right end of the discharge bin 211. The inner sidewalls of the front and rear sides of the baffle bracket 225 are provided with slide grooves 223 for limiting the sliding of the baffle 221. The baffle 221 is limited and slidably connected to the baffle bracket 225 through the slide grooves 223. The upper middle part of the baffle 221 is rotatably connected to the screw 222, and the screw 222 is threadedly connected to the baffle bracket 225 through a threaded sleeve. The upper end of the screw 222 is fixedly connected to the handwheel 224.

[0051] After the operator starts conveyor line 1, conveyor line 1 drives pusher block 213 to move. Pusher block 213 enters the feeding bin 211 and pushes the bottom hard cardboard or paperboard forward, passing under baffle 221. Due to friction, the bottom hard cardboard or paperboard drives the upper hard cardboard or paperboard to move. Baffle 221 blocks the upper hard cardboard or paperboard from moving. If it is necessary to adjust the height of the baffle according to the thickness of different hard cardboard or paperboard, simply turn handwheel 224. Handwheel 224 drives screw 222 to rotate. After the screw 222 rotates, it moves relative to the baffle bracket 225 through the threaded sleeve. Screw 222 drives baffle 221 to slide through the slide groove 223 and the baffle bracket 225. After the baffle 221 moves to the required position, stop turning handwheel 224. The position adjustment is completed.

[0052] This invention enables the unstacking and loading of rigid cardboard or paperboard of different thicknesses.

[0053] Both conveyor line 1 and conveyor line 2 5 use belt conveyors.

[0054] The drying component 3 is a drying lamp.

[0055] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
