Technical Field
[0001] This utility model relates to the field of paper processing technology, and in particular to a vacuum press roller grinding transmission device. Background Technology
[0002] Paper processing can be divided into five categories according to different processing methods: coated paper, impregnated absorbent paper, modified paper, composite paper, and mechanically processed paper. Among them, the vacuum press roll grinding transmission device is a piece of equipment used in the press section of a papermaking machine. Its main function is to dehydrate and grind the paper through the rotation and grinding action of the vacuum press roll, so as to improve the quality of the paper and production efficiency.
[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: In the use of existing technologies, fiber residues, impurities and dirt will inevitably accumulate on the surface of the press roller. If these deposits are not cleaned in time, they will gradually harden and adhere to the roller surface, affecting the grinding effect and dewatering efficiency of the press roller. The accumulation of dirt may also lead to accelerated wear on the surface of the press roller, shortening its service life and increasing equipment maintenance costs. Moreover, operators need to manually clean the surface of the press roller regularly, which not only increases labor intensity and working time, but may also cause defects on the paper surface due to untimely or incomplete cleaning, affecting product quality. Summary of the Invention
[0004] The technical problem to be solved by this utility model is that the existing technology does not have the function of cleaning the surface residue of the press roll, which leads to the accumulation of residue and may also cause the surface wear of the press roll to be aggravated, affecting the final quality of the paper. To this end, we propose a vacuum press roll grinding transmission device.
[0005] To achieve the above objectives, this application adopts the following technical solution: a vacuum press roller grinding transmission device, comprising a first base, a first control console mounted on one side of the first base, a first bracket mounted on one end of the top of the first base, a first servo motor mounted on one side of the first bracket, a press roller body mounted on the output end of the first servo motor, a vacuum machine body mounted on the other end of the first bracket, a second bracket mounted on the top of the first bracket, a first lifting cylinder mounted on the top of the second bracket, a first drive motor mounted on the telescopic end of the first lifting cylinder, a grinding roller body mounted on the output end of the first drive motor, a grinding roller body mounted on the other end of the top of the first base, a first water pump mounted on the bottom of the first base, a first input water pipe mounted on one end of the first water pump, a first high-pressure spray device mounted on the output end of the first water pump, a first water filter bracket mounted on one end of the bottom of the first base, a first dust filter screen slidably connected to the inner wall of the first water filter bracket, a first limiting pin fixedly connected to one side of the first dust filter screen, and first clamping blocks rotatably connected to both sides of the first water filter bracket via rotating shafts, with the inner wall of the first clamping block inserted into one end of the first limiting pin.
[0006] Preferably, a first sliding groove is provided at both ends of the bottom of the first base, and a first limiting rod is slidably connected to the inner wall of the first sliding groove. The inner wall of the first limiting rod is slidably connected to the surface of the first clamping block.
[0007] Preferably, both ends of the first limiting rod are provided with a first circular groove, and a first sliding rod is slidably connected to the inner wall of the first circular groove. The two ends of the first sliding rod are fixedly connected to the two sides of the inner wall of the first sliding groove.
[0008] Preferably, both ends of the first limiting rod are fixedly connected to a first spring, and the other end of the first spring is fixedly connected to one side of the inner wall of the first groove.
[0009] Preferably, a first limiting groove is provided on both sides of the inner wall of the first water filter bracket, and a first slider is slidably connected to the inner wall of the first limiting groove. One side of the first slider is fixedly connected to one side of the first dust filter.
[0010] Preferably, a second drive motor is installed on one side of the first bracket, and a first cleaning roller brush is installed at the output end of the second drive motor.
[0011] Preferably, a first baffle is installed at one end of the top of the first base.
[0012] Technical effects and advantages of this utility model: In this invention, the user rotates the first clamping block via a pivot to disengage it from the first limiting pin. The user then uses the handle on one side of the first dust filter to remove it from the inner wall of the first water filter bracket for cleaning or replacement. These deposits not only affect the pressing effect and reduce dewatering efficiency, but may also cause defects on the paper surface, affecting product quality. The rinsing by the first high-pressure spray device can effectively clean the surface of the press roller before, during, or in the intervals of pressing operations. This not only reduces the workload and time cost of manual cleaning, but also ensures that the surface of the press roller is always kept clean, thereby improving pressing efficiency and extending the service life of the press roller.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0016] Reference Figures 1-5As shown, this utility model provides a technical solution: a vacuum press roller grinding transmission device, including a first base 1, a first control console 2 installed on one side of the first base 1, a first bracket 3 installed at one end of the top of the first base 1, a first servo motor 4 installed on one side of the first bracket 3, a press roller body 5 installed at the output end of the first servo motor 4, a vacuum machine body 6 installed at the other end of the first bracket 3, a second bracket 7 installed on the top of the first bracket 3, a first lifting cylinder 8 installed on the top of the second bracket 7, a first drive motor 9 installed at the telescopic end of the first lifting cylinder 8, a grinding roller body 10 installed at the output end of the first drive motor 9, a grinding roller body 11 installed at the other end of the top of the first base 1, and a vacuum machine body 11 installed at the bottom of the first base 1. The device includes a first water pump 12, with a first input water pipe 13 installed at one end and a first high-pressure spray device 14 installed at the output end. A first water filter bracket 15 is installed at one end of the bottom of the first base 1, and a first dust filter 16 is slidably connected to the inner wall of the first water filter bracket 15. A first limiting pin 17 is fixedly connected to one side of the first dust filter 16. Both sides of the first water filter bracket 15 are rotatably connected to first clamping blocks 18 via rotating shafts, and the inner wall of the first clamping block 18 is inserted into one end of the first limiting pin 17. When the user starts the device through the first control console 2, the height of the pressing roller body 10 is adjusted by driving the first lifting cylinder 8, and then the pressing roller body is driven by controlling the first servo motor 4 and the first drive motor 9 respectively. The press roller body 5 and the pressing roller body 10 squeeze the moisture inside the paper. After the paper is conveyed to the interior of the grinding roller body 11, the grinding roller body 11 grinds the surface of the paper in the transmission process to make the paper surface smoother. At this time, the user connects the first water inlet pipe 13 to the water source, and then the first water pump 12 inputs the water source into the first high-pressure spray device 14. The first high-pressure spray device 14 sprays and washes the bottom of the press roller body 5 to clean the residual pulp, dust, and foreign matter on the surface of the press roller body 5. The vacuum machine body 6 then vacuum-extracts the small amount of water remaining on the surface of the press roller body 5 after washing, reducing the water residue on the surface of the press roller body 5. The impurities are flushed into the first base 1 through the inclined surface of the inner wall of the first base 1. Inside the dust filter 16, moisture from impurities is discharged through the perforations of the first dust filter 16 and the drain holes of the first water filter bracket 15, effectively separating impurities from moisture. The impurities remain inside the first dust filter 16 for subsequent centralized processing. When the first dust filter 16 is full of impurities, the user rotates the first clamping block 18 via the pivot, disengaging the first clamping block 18 from the first limiting pin 17. The user then uses the handle on one side of the first dust filter 16 to remove it from the inner wall of the first water filter bracket 15 for cleaning and replacement. The surface of the press roller often accumulates fiber residue, impurities, or dirt due to prolonged contact with pulp. These deposits not only affect the pressing effect and reduce dewatering efficiency but may also cause defects on the paper surface, affecting product quality.The rinsing by the first high-pressure spray device 14 effectively cleans the surface of the press rolls before, during, or in between pressing operations. This not only reduces the workload and time cost of manual cleaning but also ensures that the surface of the press rolls remains clean, thereby improving pressing efficiency and extending the service life of the press rolls.
[0017] Reference Figure 1 , Figure 4 and Figure 5 As shown in this embodiment: both ends of the bottom of the first base 1 are provided with first sliding grooves 19. The inner wall of the first sliding groove 19 is slidably connected to a first limiting rod 20. The inner wall of the first limiting rod 20 is slidably connected to the surface of the first clamping block 18. When the user inserts the first clamping block 18 into the first limiting pin 17, the first limiting rod 20 is pulled to move it along the inner wall of the first sliding groove 19, so that the first limiting rod 20 restricts the movement space of the first clamping blocks 18 on both sides, preventing them from unfolding to both sides. The connection between the first dust filter 16 and the first water filter bracket 15 is more stable through the first limiting rod 20.
[0018] Reference Figure 1 , Figure 4 and Figure 5 As shown in this embodiment: both ends of the first limiting rod 20 are provided with a first circular groove 21, and the inner wall of the first circular groove 21 is slidably connected to a first sliding rod 22. The two ends of the first sliding rod 22 are fixedly connected to the two sides of the inner wall of the first sliding groove 19. When the user moves the first limiting rod 20 through the first circular groove 21 to the surface of the first sliding rod 22 installed inside the first water filter bracket 15, the movement trajectory of the first limiting rod 20 is fixed, making it more stable when moving.
[0019] Reference Figure 1 , Figure 4 and Figure 5 As shown in this embodiment: both ends of the first limiting rod 20 are fixedly connected to the first spring 23, and the other end of the first spring 23 is fixedly connected to one side of the inner wall of the first slide groove 19. When the user pulls the first limiting rod 20 to move it to the inner wall of the first water filter bracket 15 to release the restriction of the first clamp 18, the first limiting rod 20 squeezes the first spring 23, causing the first spring 23 to store and compress. When the user needs the first limiting rod 20 to move back to its original position, the user releases the first limiting rod 20, causing the first spring 23 to release and rebound, pushing the first limiting rod 20 back to its original position automatically. The operability of the equipment is improved by the first spring 23.
[0020] Reference Figure 2 and Figure 3As shown in this embodiment: a first limiting groove 24 is provided on both sides of the inner wall of the first water filter bracket 15. A first slider 25 is slidably connected to the inner wall of the first limiting groove 24. One side of the first slider 25 is fixedly connected to one side of the first dust filter 16. When the user installs or removes the first dust filter 16, the first slider 25 moves along the inner wall of the first limiting groove 24, making the first dust filter 16 more stable when moving along the inner wall of the first water filter bracket 15.
[0021] Reference Figure 3 and Figure 4 As shown in this embodiment: a second drive motor 26 is installed on one side of the first bracket 3, and a first cleaning roller brush 27 is installed at the output end of the second drive motor 26. When the user starts the equipment, the second drive motor 26 drives the first cleaning roller brush 27, so that the first cleaning roller brush 27 cleans the surface of the press roller body 5 through the cleaning brush on the surface, thereby effectively removing impurities and particles attached to the surface of the press roller body 5, ensuring the cleanliness of the surface of the press roller body 5, and providing good conditions for subsequent grinding and transmission work.
[0022] Reference Figure 2 and Figure 4 As shown in this embodiment: a first baffle 28 is installed at one end of the top of the first base 1. When the user starts the first high-pressure spray device 14 to spray and wash the press roller body 5, the first baffle 28 allows the sprayed water to cover the part of the press roller body 5 that needs to be washed in a more concentrated manner, avoiding water splashing everywhere and wasting water resources, facilitating subsequent collection and treatment, ensuring the cleanliness of the environment around the equipment, and providing a guarantee for the continuous and stable operation of the equipment.
[0023] Working principle: Step 1: After the user starts the device via the first control console 2, the height of the pressing roller body 10 is adjusted by driving the first lifting cylinder 8 to achieve a suitable pressing position. The first servo motor 4 and the first drive motor 9 are then controlled to drive the pressing roller body 5 and the pressing roller body 10 respectively to press the moisture inside the paper. After the paper is conveyed to the grinding roller body 11, the grinding roller body 11 grinds the paper surface, making it smoother. The user connects the first water inlet pipe 13 to a water source and uses the first water pump 12 to input water into the first high-pressure spray device 14. The first high-pressure spray device 14 sprays and rinses the bottom of the pressing roller body 5 to clean its surface residue. The remaining pulp, dust, and foreign matter are removed by vacuum extraction of the small amount of water remaining after rinsing the surface of the press roller body 5 by the vacuum machine body 6, reducing water residue. The impurities after rinsing are flushed into the interior of the first dust filter 16 through the inclined surface of the inner wall of the first base 1. The filter holes of the first dust filter 16 discharge the water in the impurities through the leakage holes of the first water filter bracket 15, achieving effective separation of impurities and water. The impurities are retained in the first dust filter 16 for subsequent centralized processing. When the impurities inside the first dust filter 16 are full, the user can rotate the first clamp 18 to disconnect it from the first limiting pin 17, and then remove it from the inner wall of the first water filter bracket 15 for cleaning or replacement by using the handle on one side of the first dust filter 16. Step two: After the user inserts the first clamping block 18 into the first limiting pin 17, the user pulls the first limiting rod 20 to move it along the inner wall of the first slide groove 19, thereby limiting the movement space of the first clamping blocks 18 on both sides and preventing them from unfolding to the sides. This ensures a more stable connection between the first dust filter 16 and the first water filter bracket 15. The user moves the first limiting rod 20 along the surface of the first slide rod 22 inside the first water filter bracket 15 through the first circular groove 21, fixing its movement trajectory and further enhancing its stability. When it is necessary to release the restriction of the first clamping block 18, the user pulls the first limiting rod 20 to move it along the inner wall of the first water filter bracket 15 and squeeze the first spring 23, causing the first spring 23 to store and compress. When the user releases the first limiting rod 20, the first spring 23 releases and rebounds, pushing the first limiting rod 20 back to its original position automatically. Step 3: When the user installs or removes the first dust filter 16, the movement of the first slider 25 on the inner wall of the first limiting groove 24 ensures that the movement of the first dust filter 16 on the inner wall of the first water filter bracket 15 is more stable. The second drive motor 26 drives the first cleaning roller brush 27 to clean the surface of the press roller body 5 using the cleaning brush on its surface, effectively removing attached impurities and particles, ensuring the cleanliness of the surface of the press roller body 5, and creating good conditions for subsequent grinding and transmission work. When the first high-pressure spray device 14 is started to spray and rinse the press roller body 5, the first baffle 28 can concentrate the water flow to cover the part of the press roller body 5 that needs to be rinsed, avoiding water splashing and wasting water resources, facilitating subsequent collection and treatment, and ensuring a clean environment around the equipment.
