Description

Technical Field

[0001] This utility model relates to the field of paper processing technology, specifically to a spray-wet device for paper processing. Background Technology

[0002] The main reasons for spraying paper with water include improving paper flexibility, preventing static electricity, preventing paper deformation, and improving the working environment. Specifically: Improving paper flexibility: Spraying makes paper softer and more elastic, reducing creases and curling edges, ensuring smoother folding. Preventing static electricity: Static electricity causes paper to attract dust and impurities, affecting print quality; spraying can eliminate static electricity to some extent, improving print quality. Preventing paper deformation: Spraying helps achieve humidity balance between the paper and the environment, reducing the likelihood of paper deformation or breakage due to dryness.

[0003] Publication number CN112301793B discloses a paper processing spraying device. By installing a spraying mechanism on the frame and activating the water supply assembly to supply water to the spray heads, the paperboard is kept moist through spraying. During the packaging process, the pressing device on the paperboard is less likely to damage it, resulting in higher processing efficiency. However, this patent still has the following problems in practical use:

[0004] It is not convenient to recycle the excess water that is sprayed onto the paper, which leads to the excess water flowing directly from the device onto the ground, resulting in a higher demand for water and a waste of water resources.

[0005] A spray-wetting device for paper processing is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a spraying device for paper processing, in order to solve the problem mentioned in the background art that it is currently inconvenient to recycle and reuse excess water sprayed on paper, which leads to excess water flowing directly from the device to the ground, resulting in a higher demand for water and a waste of water resources.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a paper processing spraying device, comprising a base plate and a conveyor belt structure installed on top of the base plate;

[0008] The bottom of the base plate is provided with a water tank, and a water pump is installed on the water tank. The output end of the water pump is fixedly connected to the water tank, and a telescopic hose is installed on the output end of the water pump. A water inlet is fixedly connected to the top of the water tank, and a fixing structure is installed on the top of the base plate.

[0009] Also includes:

[0010] A collection and cleaning assembly is provided between the support legs on one side of the bottom of the base plate. The collection and cleaning assembly includes a drain outlet, which is opened inside the base plate and is symmetrically arranged in two places. A conical shell is fixedly connected to the bottom of the base plate, and the bottom of the conical shell is hollow.

[0011] Among them, a connecting plate is fixedly connected between the support legs on one side, and a filter screen is fixedly connected inside the connecting plate. The filter screen corresponds to the bottom of the conical shell, and a fixing plate is fixedly connected to one side of one of the support legs.

[0012] The first motor is mounted on the back of the fixing plate, and a rotating rod is rotatably connected to the front of the fixing plate. The output end of the first motor is fixedly connected to the fixing plate, and a through groove is opened inside one side of the connecting plate.

[0013] Preferably, a limiting rod is fixedly connected inside the through groove, and a sliding plate is slidably connected to the outside of the limiting rod.

[0014] Preferably, a spring is sleeved on the outside of the limiting rod, and the spring is fixed between the sliding plate and the connecting plate.

[0015] Preferably, a scraper is fixedly connected to one side of the slide plate, and a collection shell is connected to the top of the connecting plate, with the collection shell located on one side of the filter screen.

[0016] Preferably, the top of the base plate is provided with a movable component, the movable component includes a panel, the panel is fixed to the top of the base plate, a second motor is installed on the back of the panel, a disc is rotatably connected to the front of the panel, the output end of the second motor is fixedly connected to the disc, and a fixing column is connected to the front of the disc.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this paper processing spraying and wetting equipment can filter and recover excess water generated from spraying and wetting paper, thereby reusing it and saving resources. At the same time, it can also clean impurities on the filter screen and prevent the filter screen from clogging. The specific details are as follows:

[0020] 1. Excess water from spraying the paper flows into the drain and into the conical shell, then flows out from the bottom of the shell. It then passes through a filter screen to remove impurities before flowing into the water tank through the inlet. This process collects the excess water from the spraying process. The first motor is then activated, driving a rotating rod. This rotation presses against a sliding plate, causing it to move to the left. As the sliding plate moves, it compresses a spring, simultaneously moving a scraper that pushes away the accumulated impurities on the filter screen. The cleaned impurities are then pushed into the collection shell for collection. This causes the rotating rod to reverse, and with the sliding plate no longer pressed against it, it returns to its original position. The first motor then stops. This completes one cleaning of the filter screen. To clean the filter screen again, repeat the above steps.

[0021] 2. Start the second motor. The second motor will drive the disc to rotate, and the disc will drive the fixed column to move in a circular motion. Since the fixed column changes position during operation, it will drive the sliding frame to move. Since the fixed column moves in a circular motion, the sliding frame will move back and forth. Then the sliding frame will drive the moving block to move back and forth. Then the moving block will cause the nozzle to move back and forth, thereby increasing the spraying range of the nozzle and making the paper more evenly wetted. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 - Figure 5 The present invention provides the following technical solution:

[0030] A paper processing spraying device includes a base plate 1 and a conveyor belt structure 2 installed on top of the base plate 1. A water tank 101 is located at the bottom of the base plate 1, and a water pump 102 is installed on the water tank 101. The output end of the water pump 102 is fixedly connected to the water tank 101, and a telescopic hose 103 is installed at the output end of the water pump 102. A water inlet 1021 is fixedly connected to the top of the water tank 101, and a fixing structure 104 is installed on the top of the base plate 1. The fixing component 104 is well-known in the prior art, and its function is to limit the position of the sprayed paper, thereby facilitating packaging and fixing. A hydraulic rod can be used to move and limit the pressure plate in the fixing structure 104. A collection and cleaning component 3 is provided between the support legs on one side of the bottom of the base plate 1. The collection and cleaning component 3 includes a drain outlet 301, which is opened inside the base plate 1 and symmetrically arranged in two places. A conical shell 302 is fixedly connected to the bottom of the base plate 1. Figure 1 , 2As shown in Figure 4, the paper is placed on the conveyor belt structure 2 for conveying. Then, the water pump 102 is started, and the water in the water tank 101 is sprayed out from the nozzle 408 through the telescopic hose 103. The excess water generated by spraying the paper will flow into the drain 301 and fall into the conical shell 302. Then, it will flow out from the bottom of the conical shell 302 and pass through the filter screen 304 to filter out impurities in the water. Finally, it will fall into the water tank 101 through the inlet 1021, thus completing the collection of excess water during spraying.

[0031] Furthermore, the bottom of the conical shell 302 is hollow; a connecting plate 303 is fixedly connected between the support legs on one side, and a filter screen 304 is fixedly connected inside the connecting plate 303. Secondly, when cleaning the filter screen 304, the paper cannot be sprayed with water. The filter screen 304 corresponds to the bottom of the conical shell 302, and a fixing plate 305 is fixedly connected to one side of one of the support legs. A first motor 306 is mounted on the reverse side of the fixing plate 305, and a rotating rod 307 is rotatably connected to the front side of the fixing plate 305. The output end of the first motor 306 is fixedly connected to the fixing plate 305. Figure 3 As shown, secondly, as the filter screen 304 is used for longer, impurities on its surface will accumulate. At this time, the first motor 306 can be started. The first motor 306 will drive the rotating rod 307 to rotate. Then the rotation of the rotating rod 307 will squeeze the slide plate 310. A through groove 308 is provided inside one side of the connecting plate 303.

[0032] A limiting rod 309 is fixedly connected inside the through groove 308, and a sliding plate 310 is slidably connected to the outside of the limiting rod 309. A spring 3091 is sleeved on the outside of the limiting rod 309, and the spring 3091 is fixed between the sliding plate 310 and the connecting plate 303. A scraper 311 is fixedly connected to one side of the sliding plate 310, and a collection shell 312 is connected to the top of the connecting plate 303. Figure 2 , 3As shown, with the limiting rod 309 in place, the slide plate 310 moves to the left. As the slide plate 310 moves, it compresses the spring 3091. Simultaneously, the scraper 311 is also driven by the slide plate 310, pushing and cleaning the impurities accumulated on the filter screen 304. The cleaned impurities are then pushed into the collection shell 312 for collection. Then, the first motor 306 reverses its direction, causing the rotating rod 307 to reverse. At this point, since one side of the slide plate 310 is no longer pressed by the rotating rod 307, the spring 3091 will rebound. This causes the slide plate 310 and scraper 311 to reset, at which point the first motor 306 stops running. This completes a single cleaning of the filter screen 304. When the filter screen 304 needs to be cleaned again, the above actions can be repeated. The collection shell 312 is located on one side of the filter screen 304. Next, when it is necessary to clean the impurities inside the collection shell 312, simply pull the collection shell 312 upwards to remove it. Finally, pour the impurities inside the collection shell 312 into the trash can, and then reinsert the collection shell 312.

[0033] A movable assembly 4 is provided on the top of the base plate 1. The movable assembly 4 includes a panel 401, which is fixed to the top of the base plate 1. A second motor 402 is mounted on the back of the panel 401, and a disc 403 is rotatably connected to the front of the panel 401. The output end of the second motor 402 is fixedly connected to the disc 403. A fixing post 404 is connected to the front of the disc 403. A sliding frame 405 is slidably connected to the outside of the fixing post 404. A movable block 406 is fixedly connected to the front of the sliding frame 405. A limiting piece 407 is fixedly connected to the front of the panel 401, and the movable block 406 can slide outside the limiting piece 407. A nozzle 408 is fixedly connected to the bottom of the movable block 406. Figure 1 , 5 As shown, when the second motor 402 is started, the second motor 402 will drive the disc 403 to rotate. The disc 403 will drive the fixed column 404 to move in a circular motion. Since the position of the fixed column 404 changes during operation, it will drive the sliding frame 405 to move. Since the fixed column 404 moves in a circular motion, the sliding frame 405 will move back and forth. Then the sliding frame 405 will drive the moving block 406 to move back and forth. Then the moving block 406 will cause the nozzle 408 to move back and forth, thereby increasing the spraying range of the nozzle 408 and making the paper spraying more even. The output end of the telescopic hose 103 is fixedly connected to the nozzle 408.

[0034] Working principle: Before using this type of paper processing spraying equipment, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, firstly, the paper is placed on the conveyor belt structure 2 for conveying. Then, the water pump 102 is started, and water from the water tank 101 is sprayed out from the nozzle 408 through the telescopic hose 103. The excess water generated from wetting the paper flows into the drain 301 and falls into the conical shell 302. It then flows out from the bottom of the conical shell 302 and passes through the filter screen 304 to filter out impurities. Finally, it falls back into the water tank 101 through the inlet 1021, thus completing the collection of excess water from the wetting process. Secondly, as the filter screen 304 is used for a longer period, impurities will accumulate on its surface. At this time, the first motor 306 can be started. The first motor 306 will drive the rotating rod 307 to rotate, and the rotation of the rotating rod 307 will squeeze... The slide plate 310, in conjunction with the limiting rod 309, moves to the left. As the slide plate 310 moves, it compresses the spring 3091. Simultaneously, the scraper 311 is also driven by the slide plate 310, pushing and cleaning the impurities accumulated on the filter screen 304. The cleaned impurities are then pushed into the collection shell 312 for collection. Then, the first motor 306 reverses its rotation, causing the rotating rod 307 to reverse. At this point, since one side of the slide plate 310 is no longer pressed by the rotating rod 307, the spring 3091 rebounds, thereby resetting the slide plate 310 and the scraper 311. The first motor 306 then stops running. This completes a single cleaning of the filter screen 304. When the filter screen 304 needs to be cleaned again, the above actions are repeated.

[0035] When the second motor 402 is started, it drives the disc 403 to rotate. The disc 403 drives the fixed column 404 to move in a circular motion. As the fixed column 404 changes position during operation, it drives the sliding frame 405 to move. Since the fixed column 404 moves in a circular motion, the sliding frame 405 moves back and forth. Then, the sliding frame 405 drives the moving block 406 to move back and forth. The moving block 406 causes the nozzle 408 to move back and forth, thereby increasing the spraying range of the nozzle 408 and making the paper sprayed more evenly.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
