Description

Technical Field

[0001] This utility model relates to the field of papermaking machine technology, and in particular to a spraying device for the production of biological antibacterial single-layer paper. Background Technology

[0002] Before the invention of the papermaking machine, papermaking was a completely manual process. It involved a series of manual operations, such as soaking, boiling, and pounding plant fiber raw materials like hemp and bark, to make pulp. The pulp was then spread evenly on bamboo screens and allowed to drain and dry naturally to remove moisture, thus forming paper pulp.

[0003] The spraying device used in the production of bio-antibacterial single-layer paper refers to the spray head equipment used in the production process of bio-antibacterial single-layer paper. The humidity sensor detects the humidity of the pulp and feeds it back to the control unit. If the humidity is lower than the standard value, the control unit starts the water pump to pump water, which is then transported to the spray head through the water pipe and sprayed according to the set mode. Based on the feedback information, the water pump speed and the spray mode of the spray head are adjusted to keep the pulp humidity within the preset range.

[0004] The main frame of the existing paper machine is made of steel, carbon steel and alloy steel. During use, the staff holds a sprayer and sprays water evenly on the pulp. Since the staff cannot judge the dryness of the pulp, it is easy for some pulp to be too dry or too wet, which cannot meet the production requirements of bio-antibacterial single-layer paper. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a spraying device for the production of bio-antibacterial single-layer paper, which aims to improve the problem in the prior art where workers cannot judge the dryness and moisture content of the pulp, which easily leads to some pulp being too dry or too wet, thus failing to meet the production requirements of bio-antibacterial single-layer paper.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a spraying device for the production of bio-antibacterial single-layer paper, comprising a water tank, rotating columns fixedly connected to the front and rear sides of the right end of the inner wall of the water tank, a placement net rotatably connected to the outer walls of the two rotating columns, a water pump fixedly connected to the rear side of the inner wall of the water tank, the output end of the water pump connected to a water pipe, fixing frames fixedly connected to the front and rear ends of the right side of the outer wall of the water tank, multiple water storage blocks fixedly connected to the top of the two fixing frames, the multiple water storage blocks connected to the water pipe, and adjacent sides of the multiple water storage blocks... Each of the two fixed frames is fixedly connected to an atomizing nozzle. Rollers are rotatably connected to adjacent sides of each of the two fixed frames. A transmission belt is rotatably connected to the front side of the outer wall of each of the rollers. A fixed column is fixedly connected to the right side of the outer wall of each of the two fixed frames. A pressing roller is rotatably connected to adjacent sides of the two fixed columns. A servo motor is fixedly connected to the front end of the outer wall of the bottom pressing roller. A transmission belt is rotatably connected to the outer wall of the right roller and the outer wall of the bottom pressing roller. The rollers and the pressing roller are rotatably connected through the transmission belt. A cleaning mechanism is provided at the bottom of the two fixed frames.

[0007] The above technical solution utilizes a water tank as the core component. The water tank not only stores water but also integrates key connection and transmission structures. A placement net is connected to the right end of the inner wall of the water tank via rotating columns on the front and rear sides. This placement net holds pulp. A water pump is installed on the rear side of the inner wall of the water tank, responsible for pumping water out of the tank. Its output end is connected to external water storage blocks via water pipes, thus realizing water transportation. Two fixed frames are located at the front and rear ends of the right side of the outer wall of the water tank. Multiple water storage blocks are fixed to the top of each frame. These water storage blocks are connected to the water pipes, serving to temporarily store and distribute water. The system consists of atomizing nozzles fixedly connected between adjacent water storage blocks. These nozzles convert water into fine mist, allowing for more even spraying onto the pulp. Rollers are rotatably connected to adjacent sides of the two fixed frames. The outer walls of multiple rollers are connected via a transmission belt, enabling them to rotate synchronously for subsequent pulp transmission and pressing operations. Press rollers are connected to the right side of the outer walls of the two fixed frames via fixed columns. A servo motor is fixedly connected to the front end of the outer wall of the bottom press roller. The press rollers perform pressing and dewatering operations on the pulp, while simultaneously adjusting the pulp's humidity in conjunction with the spraying device.

[0008] As a further description of the above technical solution:

[0009] The cleaning mechanism includes a water storage tank. The left side of the outer wall of the water storage tank is fixedly connected to the right side of the outer wall of the water tank. A filter screen is fixedly connected to the middle of the inner wall of the water storage tank. A rotary valve is fixedly connected to the left side of the outer wall of the water storage tank. A threaded rod is fixedly connected to the rear side of the outer wall of the rotary valve. A sliding block is threadedly connected to the outer wall of the threaded rod. A brush is rotatably connected to the right side of the outer wall of the sliding block.

[0010] The above technical solution utilizes a water storage tank as the basic component for the cleaning mechanism. The left side of the outer wall of the water storage tank is fixedly connected to the right side of the outer wall of the water tank, ensuring a tight connection between the cleaning mechanism and the entire spraying device. This facilitates the collection and treatment of impurities and wastewater generated during the operation of the device. A filter screen is fixedly connected to the middle of the inner wall of the water storage tank. The function of the filter screen is to filter the liquid entering the water storage tank, intercepting impurities on one side of the filter screen, allowing the cleaned water to continue flowing through the filter screen. This achieves preliminary separation of impurities and prevents impurities from accumulating in the water storage tank and affecting subsequent cleaning operations. A sliding block is threadedly connected to the outer wall of the threaded rod. When the threaded rod rotates, the sliding block moves up and down along the threaded rod. A brush is rotatably connected to the right side of the outer wall of the sliding block. The brush moves with the movement of the sliding block, thereby cleaning the filter screen.

[0011] As a further description of the above technical solution:

[0012] The inner wall of the water tank is fixedly connected to the front and rear ends of the left side with a fixing plate. The bottom of the inner wall of the two fixing plates is fixedly connected to a spring. The bottom of the two springs is fixedly connected to a pressure plate. The top of the two pressure plates is fixedly connected to the bottom left side of the placement net.

[0013] The above technical solution involves setting two fixing plates at the front and rear ends of the left side of the inner wall of the water tank. These two fixing plates provide a basic structure for the fixed support of subsequent components. When the pulp is placed on the placement net, the pressure will be compressed downward by the spring, so that the pulp on the placement net will come into contact with the water in the water tank.

[0014] As a further description of the above technical solution:

[0015] Both of the fixed columns are fixedly connected to a top plate, and the top of the top plate has multiple square holes, and the inner walls of the multiple square holes are fixedly connected to sprinkler heads.

[0016] The above technical solution involves fixing a top plate to the top of two fixed columns. The top plate serves as a load-bearing component, providing an installation position for the subsequent water spraying device. Multiple square holes are opened on the top of the top plate, and water spray heads are fixedly connected to the inner walls of the multiple square holes. The water spray heads play a role in supplementing water during the pulp production process.

[0017] As a further description of the above technical solution:

[0018] A discharge box is fixedly connected to the right side of the outer wall of the two fixed columns, and a discharge plate is fixedly connected to the right side of the outer wall of the discharge box.

[0019] The above technical solution involves a discharge box fixedly connected to the right side of the outer wall of two fixed columns. The discharge box serves as a transfer structure to receive the processed pulp. A discharge plate is fixedly connected to the right side of the outer wall of the discharge box. The function of the discharge plate is to guide the pulp to be smoothly discharged from the discharge box, so that it can continue to the subsequent production process in a predetermined direction and path.

[0020] As a further description of the above technical solution:

[0021] A mobile vehicle is provided on the right side of the outer wall of the two fixed columns. A groove is provided on the top of the mobile vehicle, and a loading box is fixedly connected to the inner wall of the groove.

[0022] The above technical solution involves a mobile cart located on the right side of the outer wall of two fixed columns. The mobile cart can move flexibly, and a loading box is fixedly connected to the inner wall of the groove. The loading box is used to collect the pulp after a series of treatments, so that the pulp can be further inspected, packaged, or transported, ensuring the continuity and efficiency of the pulp production process.

[0023] As a further description of the above technical solution:

[0024] A second fixing plate is fixedly connected to the lower middle part of the outer wall of the front fixing frame, and the second fixing plate is fixedly connected to the servo motor.

[0025] The above technical solution involves fixing the servo motor to the fixed plate two, which ensures the stability of the servo motor during the operation of the device. The servo motor plays a key role in the entire device, enabling it to rotate normally to perform pressing and dewatering operations on the pulp. The fixed plate two firmly fixes the servo motor to the fixed frame, preventing the servo motor from shifting due to vibration or other external forces during operation, thereby ensuring the stable rotation of the press roller and the normal operation of the entire device.

[0026] As a further description of the above technical solution:

[0027] A controller is fixedly connected to the upper middle part of the outer wall of the front fixing frame. The controller is electrically connected to the water pump and the servo motor respectively.

[0028] The above technical solution involves electrically connecting the controller to the water pump and servo motor, enabling control of both. This ensures the water pump's start-up, stop, and speed, thereby adjusting the water spray volume to meet the pulp moisture requirements during the production of bio-antibacterial single-layer paper. For the servo motor, the controller can control its start-up, stop, speed, and rotation direction, thus precisely controlling the working state of the press roll. This ensures the press roll performs appropriate pressing and dewatering operations on the pulp, guaranteeing pulp quality and smooth production.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the pulp can be effectively soaked by the placement net inside the water tank. The water pump on the back side of the inner wall of the water tank is connected to the water pipe, which can stably draw out water and deliver it to each water storage block, ensuring that the atomizing nozzle has a continuous and stable water supply. This ensures that the atomizing nozzle can work continuously and stably, meeting the needs of pulp humidity regulation in the production process of bio-antibacterial single-layer paper.

[0031] 2. In this utility model, the filter screen in the middle of the inner wall of the water storage tank can effectively filter impurities entering the water storage tank. When impurities generated during the operation of the device enter the water storage tank with the water flow, the filter screen will intercept these impurities, allowing clean water to continue to flow through the filter screen, thereby preventing impurities from accumulating in the water storage tank and improving cleaning efficiency.

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.

[0040] Reference Figure 1 , Figure 3 and Figure 2 This utility model provides an embodiment of a spraying device for the production of bio-antibacterial single-layer paper, comprising a water tank 1. Rotating columns 3 are fixedly connected to the front and rear sides of the right end of the inner wall of the water tank 1. A placement net 4 is rotatably connected to the outer wall of the two rotating columns 3 for placing pulp. A water pump 5 is fixedly connected to the rear side of the inner wall of the water tank 1 for transporting water from the water tank 1. The output end of the water pump 5 is connected to a water pipe 6. Fixing frames 7 are fixedly connected to the front and rear ends of the right side of the outer wall of the water tank 1. Multiple water storage blocks 8 are fixedly connected to the top of each of the two fixing frames 7. The multiple water storage blocks 8 are connected to the water pipe 6, and the pumped water is transported to each water storage block 8 through the water pipe 6. Atomizing nozzles 28 are fixedly connected to adjacent sides of each of the multiple water storage blocks 8. Atomizing nozzle 28 sprays water onto the pulp. Rollers 9 are rotatably connected to adjacent sides of the two fixed frames 7 for transferring the pulp. Drive belt 10 is rotatably connected to the front side of the outer wall of multiple rollers 9. Fixed columns 11 are fixedly connected to the right side of the outer wall of the two fixed frames 7. Press rollers 12 are rotatably connected to adjacent sides of the two fixed columns 11. Servo motor 26 is fixedly connected to the front end of the outer wall of the bottom press roller 12. Drive belt 23 is rotatably connected to the outer wall of the right roller 9 and the outer wall of the bottom press roller 12. The rollers 9 and the press roller 12 are rotatably connected through drive belt 23. The press roller 12 performs pressing and dewatering operations on the pulp. A cleaning mechanism 2 is provided at the bottom of the two fixed frames 7.

[0041] Specifically, the pulp is placed in the placement net 4, which sinks due to the spring 15. The pulp is then soaked in the water tank 1. When the soaking time is up, the worker rotates the placement net 4 to pour it into the roller 9 for the next step. The water pump 5 on the back of the inner wall of the water tank 1 is started and pumps water out of the tank. The output end of the water pump 5 is connected to the water pipe 6, and the pumped water is transported to each water storage block 8 through the water pipe 6. The rollers 9 on the adjacent sides of the two fixed frames 7 are connected to each other by a transmission belt 10. When one roller 9 rotates, the other rollers 9 rotate synchronously. The pulp is placed on the rollers 9, and the rotation of the rollers 9 drives the pulp forward, realizing the transfer of the pulp in the device. The right side of the outer wall of the two fixed frames 7 is connected to the rollers 9. The press roller 12, connected by the fixed column 11, rotates under the drive of the servo motor 26. The servo motor 26 is fixedly connected to the front end of the outer wall of the bottom press roller 12. The outer wall of the right roller 9 is rotatably connected to the outer wall of the bottom press roller 12 through the transmission belt 2 13. All rollers 9 and press rollers 12 are rotatably connected through the transmission belt 2 13. When the pulp passes through the press roller 12, the press roller 12 will perform a pressing and dewatering operation on the pulp to remove excess water. Multiple water storage blocks 8 are connected to the water pipe 6, and atomizing nozzles 28 are fixedly connected to adjacent sides of the multiple water storage blocks 8. When water is delivered to the water storage block 8, the atomizing nozzles 28 will convert the water into fine water mist and spray it onto the pulp.

[0042] Reference Figure 1 , Figure 2 and Figure 5 The cleaning mechanism 2 includes a water storage tank 201. The left side of the outer wall of the water storage tank 201 is fixedly connected to the right side of the outer wall of the water tank 1. A filter screen 202 is fixedly connected to the middle of the inner wall of the water storage tank 201. The filter screen 202 intercepts impurities in the water. A rotary valve 203 is fixedly connected to the left side of the outer wall of the water storage tank 201. A threaded rod 204 is fixedly connected to the rear side of the outer wall of the rotary valve 203. Rotating the rotary valve 203 causes the sliding block 205 to move up and down along the threaded rod 204. The outer wall of the threaded rod 204 is threadedly connected to the sliding block 205. A brush 206 is rotatably connected to the right side of the outer wall of the sliding block 205. The brush 206 cleans the filter screen 202.

[0043] Specifically, the filter screen 202 in the middle of the inner wall of the water storage tank 201 filters the incoming liquid. Impurities are intercepted on one side by the filter screen 202, while clean water can continue to flow through the filter screen 202. A rotary valve 203 is fixedly connected to the left side of the outer wall of the water storage tank 201. When the rotary valve 203 rotates, the threaded rod 204 fixedly connected to the rear side of its outer wall will rotate synchronously. Since a sliding block 205 is threadedly connected to the outer wall of the threaded rod 204, according to the principle of thread transmission, when the threaded rod 204 rotates, the sliding block 205 will move up and down along the threaded rod 204. A brush 206 is rotatably connected to the right side of the outer wall of the sliding block 205. The brush 206 moves with the movement of the sliding block 205. When the sliding block 205 moves upward, the brush 206 will clean the filter screen 202.

[0044] Reference Figure 2 , Figure 3 and Figure 4 The inner wall of water tank 1 has fixed plates 14 at both the front and rear ends on the left side. The bottom of the inner wall of the two fixed plates 14 is fixedly connected to springs 15. The bottom of the two springs 15 is fixedly connected to pressure plates 16. The springs 15 and pressure plates 16 form an elastic support. The tops of the two pressure plates 16 are fixedly connected to the bottom left side of the placement net 4. The tops of the two fixed columns 11 are fixedly connected to top plates 17. The top of the top plates 17 has multiple square holes 18. The inner walls of the multiple square holes 18 are fixedly connected to sprinklers 19, which can perform additional watering operations on the pulp. The outer right side of the two fixed columns 11 is fixedly connected to a discharge box 20 to collect the processed pulp. The outer right side of the discharge box 20 is fixedly connected to a discharge plate 21 to guide the pulp to be output smoothly.

[0045] Specifically, the fixed plate 14 at the front and rear ends of the left side of the inner wall of the water tank 1 is a support structure. The spring 15 and pressure plate 16 connected to the bottom of its inner wall form an elastic support. When the placement net 4 is subjected to pressure from the pulp, the placement net 4 transmits the force to the pressure plate 16. The pressure plate 16 compresses the spring 15, and the spring 15 undergoes elastic deformation. Multiple square holes 18 are opened on the top plate 17 at the top of the two fixed columns 11. Sprinkler heads 19 are fixedly connected to the inner wall of the square holes 18. During the pulp production process, after the pulp passes through the roller 9 and the press roller 12 below, the sprinkler heads 19 can perform additional watering operations on the pulp to supplement the required humidity of the pulp and ensure that the pulp humidity meets the requirements for the production of bio-antibacterial single-layer paper. The discharge box 20 fixedly connected to the right side of the pulp outer wall of the two fixed columns 11 is used to collect the treated pulp. The discharge plate 21 further guides the pulp to be smoothly discharged from the discharge box 20.

[0046] Reference Figure 1 , Figure 2 and Figure 4A mobile cart 22 is provided on the right side of the outer wall of the two fixed columns 11 for easy movement of the collected pulp. The top of the mobile cart 22 has a groove 23, and the inner wall of the groove 23 is fixedly connected to a material box 24, providing temporary storage space. A fixing plate 25 is fixedly connected to the lower middle part of the outer wall of the front fixed frame 7 to ensure that the servo motor 26 will not shift due to vibration during operation. The fixing plate 25 is fixedly connected to the servo motor 26. A controller 27 is fixedly connected to the upper middle part of the outer wall of the front fixed frame 7. The controller 27 is electrically connected to the water pump 5 and the servo motor 26 respectively for starting and stopping.

[0047] Specifically, the movable cart 22, located on the right side of the outer wall of the two fixed columns 11, is flexibly movable. The loading box 24 within the groove 23 at its top is used to collect the pulp after it has passed through. When the pulp is output from the discharge box 20 via the discharge plate 21, it falls into the loading box 24. The loading box 24 provides temporary storage space for the pulp, facilitating further inspection, packaging, or transportation. The fixing plate 25 at the lower middle part of the outer wall of the front fixed frame 7 is fixedly connected to the servo motor 26, ensuring that the servo motor 26 is not affected by vibration or other factors during operation. Displacement occurs due to external force, and the servo motor 26 provides power to the press roller 12. Through this stable connection, the power can be stably transmitted to the press roller 12, enabling the press roller 12 to rotate normally and perform pressing and dewatering operations on the pulp. The controller 27 on the upper part of the outer wall of the front fixing frame 7 is electrically connected to the water pump 5 and the servo motor 26. The controller 27 will reduce the speed of the water pump 5 and reduce the amount of water sprayed, thereby achieving precise control of the pulp moisture. The controller 27 can control the start, stop, speed and rotation direction of the servo motor 26.

[0048] Working principle: The pulp is placed in the placement net 4 and then soaked in the water tank 1 to ensure full contact with water. The rollers 9 on adjacent sides of the two fixed frames 7 are connected to each other by a transmission belt 10. The pulp is placed on the rollers 9, and the rotation of the rollers 9 moves the pulp forward, achieving stable transmission of the pulp in the device. The press rollers 12, connected to the outer right side of the two fixed frames 7 by fixed columns 11, rotate under the drive of the servo motor 26. The servo motor 26 is fixedly connected to the front end of the outer wall of the bottom press roller 12. The outer wall of the right roller 9 is rotatably connected to the bottom press roller 12 by a transmission belt 13. All rollers 9 and press rollers 12 are connected by a transmission belt 13. A rotating connection is achieved. When the pulp passes through the press roller 12, the press roller 12 will press and dewater the pulp to remove excess water. After the water pump 5 on the back side of the inner wall of the water tank 1 is started, it will draw water out of the water tank 1. The output end of the water pump 5 is connected to the water pipe 6. The drawn water is transported to each water storage block 8 through the water pipe 6. Multiple water storage blocks 8 are connected to the water pipe 6, and each adjacent side of multiple water storage blocks 8 is fixedly connected to an atomizing nozzle 28. When the water is transported to the water storage block 8, the atomizing nozzle 28 will convert the water into fine water mist and spray it on the pulp. This atomizing spraying method can make the water more evenly distributed on the surface of the pulp and avoid local water accumulation or dryness.

[0049] Furthermore, the filter screen 202 located in the middle of the inner wall of the water storage tank 201 serves to filter impurities. During operation, when water containing impurities from the rollers 9, press rollers 12, and water tank 1 enters the water storage tank 201, the filter screen 202 intercepts these impurities, preventing their accumulation within the tank. This ensures the water in the tank can be recycled or discharged smoothly, and also provides a relatively clean environment for subsequent cleaning operations. A rotary valve 203 is fixedly connected to the left side of the outer wall of the water storage tank 201. When cleaning is required, the operator rotates the rotary valve 203. The rotation of the rotary valve 203 will drive the threaded rod 204 fixedly connected to the rear side of its outer wall to rotate synchronously. Since the outer wall of the threaded rod 204 is threadedly connected to the sliding block 205, according to the principle of thread transmission, when the threaded rod 204 rotates, the sliding block 205 will move up and down along the threaded rod 204. The right side of the outer wall of the sliding block 205 is rotatably connected to the brush 206. The brush 206 moves with the movement of the sliding block 205. When the sliding block 205 moves upward, the brush 206 will clean the filter screen 202.

Although the present utility model 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.
