Technical Field
[0001] This utility model relates to the field of vibration device technology, and in particular to a novel vibration device for the wire section of a papermaking machine. Background Technology
[0002] In the papermaking industry, the wire shaking device is very important for improving paper uniformity and the longitudinal and transverse basis weight shrinkage ratio. The shaking device mainly consists of a drive motor, a base and an eccentric shaft. When working, the drive motor drives the transmission rod to rotate, and the transmission rod drives the eccentric shaft to rotate, which in turn drives the connecting rod connected to the breast roll of the papermaking machine to move back and forth, so that the breast roll vibrates by moving back and forth.
[0003] When the vibrating device is working, the frequency and amplitude of the back-and-forth movement of the breast roller after it is connected to the connecting rod are fixed. It is impossible to adjust the vibration amplitude of the breast roller according to the operation of the paper machine, resulting in low practicality and flexibility when using the vibrating device. Utility Model Content
[0004] The purpose of this invention is to solve the problem that the frequency and amplitude of the back-and-forth movement of the breast roller after it is connected to the connecting rod are fixed when the vibrating device is working, and the vibration amplitude of the breast roller cannot be adjusted according to the operation of the paper machine, resulting in low practicality and flexibility of the vibrating device. Therefore, a new type of vibrating device for the wire section of a paper machine is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel paper machine wire section vibration device, comprising a frame and a drive motor. A housing is fixedly connected to one side of the top of the frame, which supports the housing and the drive motor. A main rod and an eccentric shaft are rotatably arranged inside the housing. The eccentric shaft drives the connecting rod to move through the main rod. A pulley in a pulley transmission assembly is respectively provided at one end of the main rod and the output end of the drive motor. A belt is sleeved on the outer side of the pulley. A connecting seat for connecting with the paper machine breast roll is provided at one end of the connecting rod. An adjustment device is provided at one end of the connecting rod to adjust the swaying amplitude of the connecting seat at one end of the connecting rod.
[0006] The effect achieved by the above components is as follows: When the shaking device is working, one end of the breast roll of the paper machine is connected to the connecting seat, the drive motor on the operating frame drives the main rod inside the box through the output end of the drive motor and the belt pulley transmission assembly, the main rod drives the eccentric shaft inside the box to rotate, the eccentric shaft drives the connecting rod to move axially, and the axial movement of the connecting rod drives the breast roll connected to one side of the connecting seat to shake on the shock-absorbing seat on the paper machine to generate shaking.
[0007] Preferably, the adjusting device includes a slot block, a sliding rod that slides inside the slot block for mounting a connecting seat, and a screw for controlling the movement of a rectangular block. The slot block is fixed to one end of a connecting rod for mounting the sliding rod and the connecting seat at one end of the connecting rod. The screw is threaded to the top of the inner wall of the slot block, and the bottom end of the screw is connected to the top of the rectangular block via a bearing. The rectangular block and the sliding rod are connected by a high-strength spring.
[0008] The effects achieved by the above components are as follows: By setting the groove block, when the shaking device is used, the sliding rod will slide up and down on the inner wall of the groove block and compress or stretch the high-strength spring when the connecting rod moves axially. The high-strength spring limits the range of movement of the sliding rod, so that when the connecting seat drives the breast roller to move axially, a small amplitude of shaking can occur, improving the shaking effect. Rotating the screw controls the screw to move up and down on the inner wall of the groove block, which can drive the rectangular block to move up and down inside the groove block. Changing the distance between the rectangular block and the sliding rod, adjusting the pressure applied by the high-strength spring to the sliding rod, thereby reducing or expanding the range of movement of the sliding rod inside the groove block, and adjusting the shaking amplitude of the connecting seat and the breast roller connected to the connecting seat.
[0009] Preferably, the adjusting device further includes a round rod located inside the groove block to limit the angle of the sliding rod when it moves inside the groove block.
[0010] The effect achieved by the above components is that when the sliding rod moves up and down inside the slot, it will slide on the outer surface of the round rod. The round rod can limit the angle of the sliding rod's movement, minimizing the deviation of the angle at both ends of the sliding rod when it moves, and improving the stability of the sliding rod and the connecting seat when they move.
[0011] Preferably, the diameter of the round rod is smaller than the inner diameter of the high-strength spring, and the two high-strength springs are located on the outer sides of the two round rods respectively.
[0012] The effect achieved by the above components is that when the sliding rod moves and causes the high-strength spring to deform, the high-strength spring will move on the outside of the round rod. The round rod can reinforce the internal shape of the high-strength spring and minimize the lateral twisting of the high-strength spring, thus affecting its normal use.
[0013] Preferably, L-shaped blocks are fixedly connected to both sides of the top end of the sliding rod, and the L-shaped blocks slide on the outside of the groove block to further limit the angle of the sliding rod.
[0014] The effect achieved by the above components is that when the sliding rod moves, the two L-shaped blocks on both sides of the top end will slide on the outside of the groove block, further restricting the angle between the end of the sliding rod near the connecting seat and the groove block, and further increasing the stability of the sliding rod and the connecting seat when moving up and down.
[0015] Preferably, an auxiliary block is fixedly connected to the top end of the screw, and protrusions are provided at both ends of the auxiliary block to facilitate the rotation of the auxiliary block.
[0016] The effect achieved by the above components is that the auxiliary block can be rotated more easily by holding the protrusions on both sides of the auxiliary block to control the rotation of the screw and adjust the position of the rectangular block inside the slot.
[0017] Preferably, the top of the groove block is provided with a fastening device that can further restrict the position of the screw and prevent the screw from rotating. The fastening device includes a groove ring and a piston rod. The groove ring is installed at the top of the groove block outside the screw. The groove ring is hollow inside and a rubber sheet is provided on one side of its inner wall. A cylinder is fixedly connected to one side of the groove ring. The piston rod slides on the inner wall of the cylinder to force air inside the cylinder into the groove ring or to extract air from the groove ring. A bolt for controlling the movement of the piston rod is rotatably provided on one side of the cylinder. The outer surface of the bolt is threaded to one side of the inner wall of the piston rod.
[0018] The effect achieved by the above components is as follows: by setting the piston rod, when using the adjustment device, after adjusting the position of the rectangular block by rotating the screw, the bolt can be rotated on one side of the cylinder. The bolt is controlled to rotate on one side of the cylinder, causing the inner wall of the piston rod to move in the direction of the outer surface of the screw towards the cylinder. The piston rod forces the air inside the cylinder into the groove ring, causing the rubber sheet on one side of the inner wall of the groove ring to bulge outward and press against the outer surface of the screw. This further restricts the position of the screw outside the groove block, and minimizes the possibility of the screw shaking and causing the rectangular block to move when the shaking device is working.
[0019] Preferably, a sealing ring is fixedly connected to one end of the cylinder. The sealing ring is made of rubber and is used to seal one end of the cylinder. When the piston rod moves inside the cylinder, it slides on the inner wall of the sealing ring.
[0020] The effect achieved by the above components is that the rubber sealing ring can further seal the outer side of the connection between the piston rod and the inner wall of the cylinder, minimizing air leakage inside the cylinder and groove ring.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting an adjustment device, when using the shaking device, the sliding rod slides up and down on the inner wall of the groove block, causing the connecting seat to drive the breast roller to move axially, which can produce a small amplitude of shaking and improve the shaking effect. Rotating the screw to move the rectangular block can adjust the pressure of the high-strength spring on the sliding rod, thereby reducing or expanding the range of movement of the sliding rod inside the groove block, adjusting the shaking amplitude of the connecting seat and the breast roller connected to the connecting seat, and improving the flexibility and practicality of the shaking device when in use.

Detailed Implementation
[0029] Example 1, such as Figure 1-2 As shown, a novel paper machine wire section vibration device includes a frame 1 and a drive motor 4. A housing 5 is fixedly connected to one side of the top of the frame 1. The frame 1 supports the housing 5 and the drive motor 4. A main rod 6 and an eccentric shaft are rotatably arranged inside the housing 5. The eccentric shaft drives the connecting rod 7 to move via the main rod 6. A pulley in a pulley transmission assembly is respectively provided at one end of the main rod 6 and the output end of the drive motor 4. A belt is sleeved on the outside of the pulley. A connecting seat 8 for connecting to the breast roll of the paper machine is provided at one end of the connecting rod 7. An adjustment device 2 is provided to adjust the swaying amplitude of the connecting seat 8 at one end of the connecting rod 7. When the vibration device is working, one end of the paper machine breast roll is connected to the connecting seat 8. The drive motor 4 on the operating frame 1 drives the main rod 6 inside the housing 5 through the output end of the drive motor 4 and the belt pulley transmission assembly. The main rod 6 drives the eccentric shaft inside the housing 5 to rotate. The eccentric shaft drives the connecting rod 7 to move axially. The axial movement of the connecting rod 7 causes the breast roll connected to one side of the connecting seat 8 to sway on the shock absorber seat on the paper machine, generating vibration.
[0030] Reference Figure 1-4As shown, in this embodiment: the adjusting device 2 includes a slot 21, a sliding rod 22 that slides inside the slot 21 for mounting the connecting seat 8, and a screw 23 that controls the movement of the rectangular block 24. The slot 21 is fixed to one end of the connecting rod 7 for mounting the sliding rod 22 and the connecting seat 8 to one end of the connecting rod 7. The screw 23 is threaded to the top of the inner wall of the slot 21, and the bottom of the screw 23 is connected to the top of the rectangular block 24 through a bearing. The rectangular block 24 and the sliding rod 22 are connected by a high-strength spring 25. By setting the slot 21, when the shaking device is used, the sliding rod 22 will slide up and down on the inner wall of the slot 21 when the connecting rod 7 moves axially. The high-strength spring 25 is compressed or stretched to limit the movement range of the sliding rod 22. This allows the connecting seat 8 to cause a small amount of swaying when it drives the breast roller to move axially, thus improving the vibration effect. Rotating the screw 23 controls the screw 23 to move up and down on the inner wall of the groove block 21, which in turn drives the rectangular block 24 to move up and down inside the groove block 21. This changes the distance between the rectangular block 24 and the sliding rod 22, and adjusts the pressure applied by the high-strength spring 25 to the sliding rod 22, thereby reducing or expanding the movement range of the sliding rod 22 inside the groove block 21 and adjusting the swaying amplitude of the connecting seat 8 and the breast roller connected to the connecting seat 8.
[0031] Reference Figure 2-4 As shown in this embodiment, the adjusting device 2 further includes a round rod 26. The round rod 26 is located inside the groove block 21 and is used to limit the angle of the sliding rod 22 when it moves inside the groove block 21. When the sliding rod 22 moves up and down inside the groove block 21, it will slide on the outer surface of the round rod 26. The round rod 26 can limit the angle of the sliding rod 22 when it moves, so as to avoid the angle of the left and right ends of the sliding rod 22 from deflecting as much as possible, thereby improving the stability of the sliding rod 22 and the connecting seat 8 when they move. The diameter of the round rod 26 is smaller than the inner diameter of the high-strength spring 25. The two high-strength springs 25 are located on the outside of the two round rods 26 respectively. When the sliding rod 22 moves and causes the high-strength spring 25 to deform, the high-strength spring 25 will move on the outside of the round rod 26. The round rod 26 can reinforce the internal shape of the high-strength spring 25, so as to avoid the high-strength spring 25 from being twisted laterally and affecting normal use.
[0032] Reference Figure 2-4As shown in this embodiment: L-shaped blocks 27 are fixedly connected to both sides of the top of the sliding rod 22. The L-shaped blocks 27 slide on the outside of the groove block 21 to further limit the angle of the sliding rod 22. When the sliding rod 22 moves, the two L-shaped blocks 27 on both sides of the top will slide on the outside of the groove block 21 to further limit the angle between the end of the sliding rod 22 near the connecting seat 8 and the groove block 21, thereby further increasing the stability of the sliding rod 22 and the connecting seat 8 when moving up and down. An auxiliary block 28 is fixedly connected to the top of the screw 23. The two ends of the auxiliary block 28 are respectively provided with protrusions that facilitate the rotation of the auxiliary block 28. By holding the protrusions on both sides of the auxiliary block 28, it is easier to rotate the auxiliary block 28 to control the rotation of the screw 23 and adjust the position of the rectangular block 24 inside the groove block 21.
[0033] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment: the top of the slot block 21 is provided with a fastening device 3 that can further restrict the position of the screw 23 and prevent the screw 23 from rotating. The fastening device 3 includes a slotted ring 31 and a piston rod 34. The slotted ring 31 is installed on the top of the slot block 21 outside the screw 23. The slotted ring 31 is hollow inside and a rubber sheet 32 is provided on one side of the inner wall. A cylinder 33 is fixedly connected to one side of the slotted ring 31. The piston rod 34 slides on the inner wall of the cylinder 33 to force the air inside the cylinder 33 into the slotted ring 31 or to extract the air from the slotted ring 31. A bolt 35 is rotatably provided on one side of the cylinder 33 to control the movement of the piston rod 34. The outer surface of the bolt 35 is flush with the inner surface of the piston rod 34. The cylinder 33 is threaded on one side. By setting the piston rod 34, when using the adjustment device 2, after adjusting the position of the rectangular block 24 by rotating the screw 23, the bolt 35 can be rotated on one side of the cylinder 33. The bolt 35 is controlled to rotate on one side of the cylinder 33, so that the inner wall side of the piston rod 34 moves in the direction of the outer surface of the screw 23 towards the cylinder 33. The piston rod 34 forces the air inside the cylinder 33 into the groove ring 31, so that the rubber sheet 32 on one side of the inner wall of the groove ring 31 protrudes outward and presses against the outer surface of the screw 23. This further restricts the position of the screw 23 outside the groove block 21, and avoids the screw 23 from shaking and causing the position of the rectangular block 24 to move when the shaking device is working.
[0034] Reference Figure 3 , Figure 4 and Figure 5As shown in this embodiment: a sealing ring 36 is fixedly connected to one end of the cylinder 33. The sealing ring 36 is made of rubber and is used to seal one end of the cylinder 33. When the piston rod 34 moves inside the cylinder 33, it will slide on the inner wall of the sealing ring 36. The rubber sealing ring 36 can further seal the outer side of the connection between the piston rod 34 and the inner wall of the cylinder 33, so as to avoid air leakage inside the cylinder 33 and the groove ring 31 as much as possible.
[0035] Working principle: When the shaking device is working, one end of the breast roll of the paper machine is connected to the connecting seat 8. The drive motor 4 on the operating frame 1 drives the main rod 6 inside the housing 5 through the output end of the drive motor 4 and the belt and pulley transmission assembly. The main rod 6 drives the eccentric shaft inside the housing 5 to rotate, which in turn drives the connecting rod 7 to move axially. The axial movement of the connecting rod 7 causes the breast roll connected to one side of the connecting seat 8 to shake on the shock absorber seat on the paper machine, generating shaking. When the connecting seat 8 drives the breast roll to move axially, a small amount of shaking can occur. When it is necessary to adjust the shaking amplitude, the screw 23 is rotated to control the screw 23 to move up and down on the inner wall of the groove block 21, which can drive the rectangular block 24 to move up and down inside the groove block 21, changing the rectangular block 24. The distance between block 24 and sliding rod 22 is adjusted, and the pressure applied to sliding rod 22 by high-strength spring 25 is adjusted to reduce or expand the range of movement of sliding rod 22 inside groove block 21, thereby reducing the sway amplitude of connecting seat 8 and the breast roller connected to connecting seat 8. After adjusting the position of rectangular block 24, bolt 35 can be rotated on one side of cylinder 33 to control bolt 35 to rotate on one side of cylinder 33, so that the inner wall side of piston rod 34 moves in the direction of cylinder 33 on the outer surface of screw 23. Through piston rod 34, air inside cylinder 33 is squeezed into groove ring 31, so that rubber sheet 32 on one side of inner wall of groove ring 31 protrudes outward and abuts against the outer surface of screw 23, thereby further restricting the position of screw 23 outside groove block 21.
