Description

Technical Field

[0001] This utility model relates to the fields of pulp manufacturing and papermaking, and in particular to a paper machine wire section edge plate device. Background Technology

[0002] The wire section edge guard device is a mechanical device installed in the wire section of a paper machine. It is mainly used to control and guide the flow of pulp wire, ensure uniform distribution of pulp, and prevent the edges of the wire from shifting or undulating, thereby improving paper quality and production efficiency.

[0003] When the mounting bracket is installed on the paper machine with bolts, the baffle bracket can be slid to a certain position in the inner wall of the mounting bracket according to the width and position of the wire section of the paper machine, and then fixed with bolts. This allows one side of the two baffle brackets to limit the two sides of the wire section. Since the side of the baffle bracket that contacts the wire section is usually a flat, rigid structure, when the wire section slightly shifts and contacts the baffle, sliding friction will form between the two. Long-term operation will lead to increased wear on the edge of the wire section, reducing its service life. At the same time, the resistance generated by friction will further aggravate the tension fluctuation of the wire section, affecting the stability of operation. Utility Model Content

[0004] The technical problem this utility model aims to solve is as follows: When the mounting frame is installed on the paper machine with bolts, the baffle frame can be slid to a certain position in the inner wall of the mounting frame according to the width and position of the wire section of the paper machine, and then fixed with bolts, so that one side of the two baffle frames limits the two sides of the wire section. Since the side of the baffle frame that contacts the wire section is usually a flat rigid structure, when the wire section slightly shifts and contacts the baffle, sliding friction will be formed between the two. Long-term operation will lead to increased wear on the edge of the wire section, reducing its service life. At the same time, the resistance generated by friction will further aggravate the tension fluctuation of the wire section, affecting the operational stability.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a paper machine wire guide plate device, including a mounting frame and bolts. A baffle frame is slidably installed on the inner wall of the mounting frame. After the baffle frame slides to a certain position in the inner wall of the mounting frame, it is fixed and limited by bolts. An auxiliary device is provided on one side of the baffle frame. The auxiliary device can be made by installing several round rollers on one side of the baffle frame, so that it moves with the wire on the paper machine, thereby reducing the sliding friction between the baffle frame and the wire, reducing the wear on both sides of the wire, and achieving the protective effect.

[0006] Preferably, the auxiliary device includes a rectangular rod, one side of which is fixedly mounted on one side of the baffle frame; a plurality of sprocket rods, one end of which is mounted through one side of the rectangular rod; a plurality of circular rollers, one side of which is fixedly mounted on one side of the sprocket rod; and a drive mechanism, wherein the drive mechanism is disposed between the outer surface of the sprocket rod and one side of the rectangular rod, for driving the sprocket rod and the circular rollers to rotate.

[0007] The effects achieved by the aforementioned components are as follows: By setting up auxiliary devices, before using the paper machine, the mounting frame is first installed on the paper machine with bolts. During use, the baffle frame can be slid to a certain position within the inner wall of the mounting frame according to the width and position of the wire section of the paper machine, and then fixed with bolts. This limits the two sides of the wire section on one side of the baffle frame, causing the outer surfaces of several rollers to adhere tightly to both sides of the wire section. When the paper machine is running, during the wire section conveying process, the drive mechanism can be activated to drive several sprockets and rollers to rotate in the direction of the wire section's movement. This reduces the sliding friction between the baffle frame and the wire section, reduces wear on the edges of the wire section, increases the service life of the wire section, reduces resistance to the wire section, and makes its operation more stable. The working principle of the paper machine wire section is mainly that a high-speed rotating conveyor belt transports wet pulp from the forming section to the pressing section of the paper machine. The pulp is evenly distributed on the wire section, undergoes preliminary dewatering, and removes excess water through vibration and water absorption to form wet paper.

[0008] Preferably, a bearing is fixedly mounted on the outer surface of the sprocket rod, and the outer ring of the bearing is fixedly mounted on one side of the rectangular rod.

[0009] The effect achieved by the above components is that by setting bearings, the rotational wear between the sprocket rod and the rectangular rod can be reduced, making rotation easier.

[0010] Preferably, the drive mechanism includes a plurality of chains, wherein a plurality of sprocket rods are connected in series by a plurality of chains; a motor, wherein the output end of the motor is fixedly connected to one side of one of the sprocket rods by means of a coupling; and a bracket, wherein the two ends of the bracket are respectively fixedly mounted on one side of a rectangular rod and one side of the motor.

[0011] The effect achieved by the above components is as follows: by setting up a drive mechanism, when the rollers limit the edge of the mesh, the motor on the bracket can be started to drive one of the sprocket rods to rotate. Under the transmission of several chains, it can drive several sprocket rods to rotate in the same direction, thereby driving several rollers to rotate in the direction of the mesh movement. This reduces the sliding friction between the two, avoids wear on the edge of the mesh, improves service life, reduces resistance, and improves the stability of the mesh operation.

[0012] Preferably, the auxiliary device further includes a limiting mechanism, which includes two protrusions and a roller frame, wherein one side of the protrusions is fixedly mounted on one side of the rectangular rod; two springs, wherein the two ends of the two springs are respectively fixedly mounted on one side of the two protrusions and one side of the roller frame; and a conveyor belt, wherein the two ends of the inner wall of the conveyor belt are respectively sleeved on the outer surfaces of the two ends of the roller frame.

[0013] The effect achieved by the above components is as follows: by setting a limiting mechanism, when the baffle frame and several rollers are limited near the edge of the mesh, the roller frame is first pulled up to a certain height, causing the spring to contract. Then, when the outer surface of the roller is in contact with the side of the mesh for limiting, the roller frame can be released, so that under the reset action of the spring, the surface of the conveyor belt is pressed against the upper edge of the mesh to limit it, making it less likely to warp and improving the limiting effect of the baffle frame.

[0014] Preferably, the limiting mechanism further includes two telescopic rods, wherein the outer surface of the telescopic rods is inserted into the inner wall of the spring, and both ends are respectively fixedly installed on one side of the two protrusions and one side of the roller frame.

[0015] The effect achieved by the above components is that by setting up the telescopic rod, the inner wall of the spring can be supported and reinforced, making it less prone to damage during use and increasing its service life.

[0016] Preferably, a reinforcing rod is fixedly installed on both sides of the protrusion, and one side of the reinforcing rod is fixedly installed on one side of the rectangular rod.

[0017] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the protrusion and the rectangular rod can be increased, making the connection more solid and stable.

[0018] The beneficial effects of this utility model are:

[0019] By setting up auxiliary devices, before using the paper machine, the mounting frame is first installed on the paper machine with bolts. When in use, the baffle frame can be slid to a certain position in the inner wall of the mounting frame according to the width and position of the wire section of the paper machine, and then fixed with bolts. This causes one side of the two baffle frames to limit the two sides of the wire section. This will cause the outer surfaces of several rollers to be tightly attached to the two sides of the wire section. When the paper machine is running, during the wire section conveying process, the drive mechanism can be activated to drive several sprockets and rollers to rotate in the direction of the wire section's movement. This reduces the sliding friction between the baffle frame and the wire section, reduces wear on the edges of the wire section, increases the service life of the wire section, reduces resistance to the wire section, and makes its operation more stable.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Figure 1-6The paper machine wire guide plate device shown includes a mounting frame 1 and bolts 4. A baffle frame 3 is slidably installed on the inner wall of the mounting frame 1. After the baffle frame 3 slides to a certain position in the inner wall of the mounting frame 1, it is fixed and limited by the bolts 4. An auxiliary device 2 is provided on one side of the baffle frame 3. The auxiliary device 2 can be made to move with the wire section of the paper machine by installing several round rollers 23 on one side of the baffle frame 3, thereby reducing the sliding friction between the baffle frame 3 and the wire section, reducing the wear on both sides of the wire section, and achieving the protective effect.

[0031] Figure 1-6 The auxiliary device 2 shown includes a rectangular rod 21, one side of which is fixedly mounted on one side of the baffle frame 3; a plurality of sprocket rods 22, one end of which is mounted through one side of the rectangular rod 21; a plurality of circular rollers 23, one side of which is fixedly mounted on one side of the sprocket rod 22; and a drive mechanism 24, which is disposed between the outer surface of the sprocket rod 22 and one side of the rectangular rod 21, for driving the sprocket rod 22 and the circular rollers 23 to rotate. By setting auxiliary device 2, before using the paper machine, the mounting frame 1 is first installed on the paper machine with bolts 4. When in use, according to the width and position of the wire section of the paper machine, the baffle frame 3 can be slid to a certain position in the inner wall of the mounting frame 1, and then fixed with bolts 4, so that one side of the two baffle frames 3 limits the two sides of the wire section. This will cause the outer surfaces of several rollers 23 to be tightly attached to the two sides of the wire section. When the paper machine is running, during the wire section conveying process, the drive mechanism 24 can be activated to drive several sprocket rods 22 and rollers 23 to rotate in the direction of the wire section's movement. This reduces the sliding friction between the baffle frame 3 and the wire section, reduces wear on the edges of the wire section, improves the service life of the wire section, reduces resistance to the wire section, and makes its operation more stable. The working principle of the paper machine wire section is mainly that the wet pulp is transported from the forming part of the paper machine to the pressing part by a high-speed rotating conveyor belt. The pulp is evenly distributed on the wire section, undergoes preliminary dewatering, and removes excess water through vibration, water absorption, etc., to form wet paper. A bearing 26 is fixedly mounted on the outer surface of the sprocket rod 22, and the outer ring of the bearing 26 is fixedly mounted on one side of the rectangular rod 21. By setting the bearing 26, the rotational wear between the sprocket rod 22 and the rectangular rod 21 can be reduced, facilitating rotation.

[0032] Figure 1-6The drive mechanism 24 shown includes several chains 241, wherein several sprocket rods 22 are connected in series by the chains 241; a motor 243, wherein the output end of the motor 243 is fixedly connected to one side of one of the sprocket rods 22 via a coupling; and a bracket 242, wherein both ends of the bracket 242 are fixedly mounted on one side of a rectangular rod 21 and one side of the motor 243, respectively. By setting up the drive mechanism 24, when the circular roller 23 limits the edge of the mesh section, the motor 243 on the bracket 242 can be activated to drive one of the sprocket rods 22 to rotate. Under the transmission of the several chains 241, it can drive the several sprocket rods 22 to rotate in the same direction, thereby driving the several circular rollers 23 to rotate in the direction of movement of the mesh section. This reduces the sliding friction between them, avoids wear on the edge of the mesh section, improves service life, reduces resistance, and improves the stability of the mesh section operation.

[0033] Figure 1-6 The auxiliary device 2 shown also includes a limiting mechanism 25, which includes two protrusions 251 and a roller frame 253, wherein one side of the protrusions 251 is fixedly mounted on one side of the rectangular rod 21; two springs 252, wherein the two ends of the two springs 252 are respectively fixedly mounted on one side of the two protrusions 251 and one side of the roller frame 253; and a conveyor belt 254, wherein the two ends of the inner wall of the conveyor belt 254 are respectively sleeved on the outer surfaces of the two ends of the roller frame 253. By setting a limiting mechanism 25, when limiting the baffle frame 3 and several rollers 23 near the edge of the mesh, the roller frame 253 is first pulled upward to a certain height, causing the spring 252 to contract. Then, when the outer surface of the roller 23 is in contact with the side of the mesh for limiting, the roller frame 253 can be released, so that under the reset action of the spring 252, the surface of the conveyor belt 254 is pressed against the upper edge of the mesh to limit it, making it less likely to warp and improving the limiting effect of the baffle frame 3.

[0034] Figure 1-6 The limiting mechanism 25 shown also includes two telescopic rods 255. The outer surface of the telescopic rods 255 is inserted into the inner wall of the spring 252, and both ends are fixedly installed on one side of the two protrusions 251 and one side of the roller frame 253, respectively. By setting the telescopic rods 255, the inner wall of the spring 252 can be supported and reinforced, making it less prone to damage during use and extending its service life. Reinforcing rods 256 are fixedly installed on both sides of the protrusions 251, and one side of the reinforcing rod 256 is fixedly installed on one side of the rectangular rod 21. By setting the reinforcing rods 256, the connection area between the protrusions 251 and the rectangular rod 21 can be increased, making the connection more secure and stable.

[0035] Working principle: Before using the paper machine, the mounting frame 1 is installed on the paper machine with the help of bolts 4. When in use, the baffle frame 3 can be slid to a certain position in the inner wall of the mounting frame 1 according to the width and position of the wire section of the paper machine, and then fixed with bolts 4. This causes one side of the two baffle frames 3 to limit the two sides of the wire section. This will cause the outer surfaces of several rollers 23 to be tightly attached to the two sides of the wire section. When the paper machine is running, during the wire section conveying process, the motor 243 on the bracket 242 can be started to drive one of the sprocket rods 22 to rotate. Under the transmission of several chains 241, it can drive several sprocket rods 22 to rotate in the same direction, thereby driving several rollers 23 to rotate in the same direction as the wire section. This reduces the sliding friction between the baffle frame 3 and the wire section, reduces the wear on the edge of the wire section, improves the service life of the wire section, reduces the resistance to the wire section, and makes its operation more stable. Meanwhile, when the baffle frame 3 and several rollers 23 are positioned near the edge of the wire section, the roller frame 253 is first pulled upward to a certain height, causing the spring 252 to contract. Then, when the outer surface of the roller 23 is in contact with the side of the wire section for positioning, the roller frame 253 can be released, so that under the reset action of the spring 252, the surface of the conveyor belt 254 is pressed against the upper edge of the wire section for positioning, making it less prone to edge curling and improving the positioning effect of the baffle frame 3. The working principle of the wire section of the paper machine is mainly to transport wet pulp from the forming part of the paper machine to the pressing part through a high-speed rotating conveyor belt. The pulp is evenly distributed on the wire section, undergoes preliminary dewatering, and removes excess water through vibration, water absorption, etc., to form wet paper.
