Description

Technical Field

[0001] This utility model relates to the technical field of paper machine dewatering devices, and in particular to a dewatering device with adjustable water-throwing angle of paper machine idler rollers. Background Technology

[0002] In the papermaking process, paper dehydration is a crucial step. Traditional paper dehydration equipment mainly achieves dehydration through methods such as pressing and vacuum suction. With the development of papermaking technology, the requirements for paper quality and production efficiency are becoming increasingly stringent, and traditional dehydration equipment has gradually revealed some shortcomings, failing to meet the needs of modern papermaking processes.

[0003] Traditional equipment has fixed roller positions and angles, making it impossible to adjust them according to paper type and production needs. This limits the equipment's versatility and applicability, and it cannot meet the production requirements of various types of paper. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a dewatering device with an adjustable water-throwing angle for paper machine rollers.

[0005] This utility model is achieved using the following technical solution: a dewatering device with an adjustable water-spraying angle for a paper machine idler roller, comprising a vacuum dewatering protection box, wherein a connecting block is provided inside the vacuum dewatering protection box, and two connecting blocks are provided. An electric telescopic rod is fixedly connected to the bottom end of each of the two connecting blocks, and a connecting plate is fixedly connected to the bottom end of each of the electric telescopic rods, and two connecting plates are provided. An idler roller body is fixedly connected to one end of the two connecting plates that are close to each other. Vacuum suction holes are provided on the surface of the idler roller body, and a high-precision vacuum sensor is installed inside the idler roller body.

[0006] The above technical solution allows for adjustment of the roller's height via the telescopic movement of the electric telescopic rod, thereby changing the roller's angle. This enables flexible adjustment based on paper thickness and dewatering requirements, improving dewatering efficiency and paper quality. Connecting blocks and plates securely connect the electric telescopic rod to the roller body, ensuring transmission stability and reliability, and guaranteeing stable roller operation at different positions and angles. The vacuum suction holes on the surface of the idler roller generate negative pressure under the action of a vacuum pump, effectively extracting moisture from the paper to achieve dewatering. It is the core component of the dewatering device. A high-precision vacuum sensor is installed inside the idler roller to monitor the vacuum level in real time, ensuring its stability during dewatering. When the vacuum level deviates from the set range, an alarm is issued promptly, reminding operators to check and adjust, thus guaranteeing the stability and reliability of the dewatering effect.

[0007] As a further improvement to the above solution, a top plate is installed on the top of the vacuum dehydration protective box, and a guide slot is opened at the top of the top plate. There are two guide slots, and a side sealing plate is snapped into the inner wall of the two guide slots. There are two side sealing plates, and a lifting rod is fixedly connected to one end of the two side sealing plates that are close to each other. There are two lifting rods.

[0008] Through the above technical solution, the top plate is installed on the top of the vacuum dehydration protective box, serving as protection and support, while also providing a guiding structure for the installation and movement of the side sealing plates. The guide slots allow for easy installation and removal of the side sealing plates, facilitating maintenance and cleaning of the interior of the vacuum dehydration protective box, and ensuring the stability and reliability of the side sealing plate installation, preventing displacement during operation. The side sealing plate is installed inside the guide slot and cooperates with the side wall of the vacuum dehydration protective box to provide a seal, prevent vacuum leakage, ensure the stability of the vacuum level during dehydration, and thus improve the dehydration effect. The lifting rod allows operators to quickly disassemble and install the side sealing plate, improving equipment maintenance efficiency and facilitating inspection and replacement of the side sealing plate when needed, ensuring its sealing performance.

[0009] As a further improvement to the above solution, a servo motor is fixedly connected to the left end of the vacuum dehydration protection box, and two servo motors are provided. A transmission screw is provided inside the vacuum dehydration protection box, and two transmission screws are provided. The output ends of the two servo motors on the right end are connected to the left end of the two transmission screws through the inside of the vacuum dehydration protection box. A transmission sleeve is connected to the surface of the two transmission screws, and two transmission sleeves are provided. Two connecting blocks are fixedly connected to the surface of the two transmission sleeves. The surface of the two connecting blocks is fixedly connected to the inner wall of the mounting plate. Two mounting plates are provided, and the bottom ends of the two mounting plates are fixedly connected to the top ends of the two connecting plates.

[0010] Through the above technical solution, the transmission screw converts the power of the servo motor into linear motion, driving the transmission sleeve to move along the screw. The transmission sleeve is fixedly connected to the connecting block, thereby realizing the horizontal movement of the connecting block and the idler roller body, and achieving the adjustment of the idler roller spacing. This driving method has the advantages of high transmission accuracy, good stability, and long service life, ensuring the accuracy and reliability of idler roller spacing adjustment.

[0011] As a further improvement to the above solution, a bottom plate is fixedly connected to the bottom of the inner wall of the vacuum dehydration protective box, and a number of water seepage holes are provided on the surface of the bottom plate.

[0012] With the above technical solution, the base plate is fixedly installed on the bottom of the inner wall of the vacuum dehydration protective box, serving as support and load-bearing, while also providing a drainage channel for the water generated during the dehydration process. The drainage holes allow the extracted water to drain smoothly out of the vacuum dehydration protective box, preventing water accumulation inside the box, keeping the inside dry, avoiding corrosion or damage to the internal components of the equipment, extending the service life of the equipment, and also helping to maintain the normal operation of the dehydration process.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention enables the dewatering device to adapt to paper of different thicknesses and moisture levels through the adjustable spacing and height of the rollers, thereby optimizing the dewatering effect and improving the quality and uniformity of the paper. The real-time monitoring and automatic alarm function of the high-precision vacuum sensor ensures that the vacuum level is always in the optimal working range (-18kPa to -25kPa), avoiding uneven dewatering or paper damage caused by unstable vacuum level. This utility model, through the combined design of a transmission screw and an electric telescopic rod, allows the angle and position of the idler roller to be quickly adjusted according to production needs, adapting to the production of different specifications and types of paper, and improving the versatility and flexibility of the equipment. Real-time monitoring and automatic alarm functions can promptly detect abnormal vacuum levels, reminding operators to check the sealing status of the side sealing plates, thus avoiding prolonged downtime and increased maintenance costs due to equipment failure.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] Example: Please combine Figure 1-4 The paper machine roller dewatering device with adjustable water-spraying angle in this embodiment includes a vacuum dewatering protection box 1. The vacuum dewatering protection box 1 is provided with a connecting block 9. There are two connecting blocks 9. The bottom of each connecting block 9 is fixedly connected to an electric telescopic rod 12. The bottom of each electric telescopic rod 12 is fixedly connected to a connecting plate 11. There are two connecting plates 11. The ends of the two connecting plates 11 that are close to each other are fixedly connected to a roller body 13. Vacuum suction holes 14 are opened on the surface of the roller body 13. There are several vacuum suction holes 14. A high-precision vacuum sensor is installed inside the roller body 13.

[0018] The top of the vacuum dehydration protective box 1 is equipped with a top plate 2, and the top of the top plate 2 is provided with a guide groove 3, and there are two guide grooves 3.

[0019] Two side sealing plates 4 are snapped into the inner walls of the two guide slots 3. There are two side sealing plates 4. A lifting rod 5 is fixedly connected to one end of the two side sealing plates 4 that is close to each other. There are two lifting rods 5.

[0020] A servo motor 6 is fixedly connected to the left end of the vacuum dehydration protection box 1. There are two servo motors 6. There are two transmission screws 7 inside the vacuum dehydration protection box 1. The output ends of the two servo motors 6 on the right end are connected to the left end of the two transmission screws 7 through the inside of the vacuum dehydration protection box 1.

[0021] Two transmission screws 7 are connected to transmission sleeves 8 on their surfaces. There are two transmission sleeves 8, and two connecting blocks 9 are fixedly connected to the surfaces of the two transmission sleeves 8.

[0022] The surfaces of the two connecting blocks 9 are fixedly connected to the inner wall of the mounting plate 10. There are two mounting plates 10, and the bottom ends of the two mounting plates 10 are fixedly connected to the top ends of the two connecting plates 11.

[0023] A bottom plate 15 is fixedly connected to the bottom of the inner wall of the vacuum dehydration protective box 1. A number of water seepage holes 16 are provided on the surface of the bottom plate 15.

[0024] Two transmission sleeves 8, connecting block 9, mounting plate 10, connecting plate 11, electric telescopic rod 12 and a roller body 13 form a group, for a total of five groups.

[0025] The implementation principle of the paper machine idler roller dewatering device with adjustable dewatering angle in this embodiment is as follows: A servo motor 6 drives the transmission screw 7 to rotate, and the transmission sleeve 8 moves on the transmission screw 7, thereby driving the connecting block 9, mounting plate 10, and connecting plate 11 to move horizontally, thus adjusting the spacing between each set of idler rollers. The extension and retraction of the electric telescopic rod 12 can adjust the height of the connecting plate 11, thereby changing the vertical position of the idler rollers. Combined with the spacing adjustment, this allows for flexible adjustment of the idler roller angle to adapt to the dewatering requirements of different types of paper.

[0026] When the paper passes over the surface of the idler roller body 13, the vacuum suction holes 14 on the surface of the idler roller generate negative pressure under the action of the vacuum pump, which extracts the moisture from the paper and achieves dehydration. The bottom plate 15 inside the vacuum dehydration protective box 1 is provided with drainage holes 16, through which the extracted moisture is discharged, keeping the inside of the protective box dry.

[0027] A high-precision vacuum sensor (accuracy ±0.1 kPa, range -10 kPa to -30 kPa) installed inside the idler roller body 13 monitors the vacuum level in real time and transmits the data to the data analysis system at a frequency of 1 time per second. When the vacuum level deviates from the set optimal working range (-18 kPa to -25 kPa), the system automatically triggers an audible and visual alarm to remind the operator to check the sealing status of the side sealing plate 4 to ensure the stability of the vacuum level, thereby ensuring the smooth progress of the dewatering process.
