Description

Technical Field

[0001] This utility model relates to the field of papermaking blanket technology, and in particular to a papermaking blanket trimming device. Background Technology

[0002] Papermaking felts are fabric felts used in the papermaking industry for paper forming and conveying. They are usually woven from special synthetic fibers or metal wires. According to their position on the papermaking machine, they can be divided into wet felts, upper felts, and dry felts. Their function is to support the formation, transfer, and dehydration of wet paper.

[0003] However, in actual use, it was found that during the operation of the papermaking felt on the papermaking machine, the two sides of the papermaking felt would come into contact with the deviation device of the papermaking machine, resulting in friction. This friction would cause the warp yarns of the papermaking felt to detach from the felt and form burrs. The presence of burrs would cause the warp yarns of the felt to be continuously pulled away. The pulled-away warp yarns would wrap around the rollers of the papermaking machine, affecting the normal operation of the papermaking machine, and would also have a negative impact on the service life of the papermaking felt. Utility Model Content

[0004] The technical problem this invention aims to solve is that during the operation of the papermaking felt on the papermaking machine, the two sides of the papermaking felt come into contact with the deviation device of the papermaking machine, resulting in friction. This friction causes the warp yarns of the papermaking felt to detach from the felt and form burrs. The presence of burrs causes the warp yarns of the felt to be continuously pulled away, and the pulled-away warp yarns become entangled on the rollers of the papermaking machine, affecting the normal operation of the papermaking machine and also negatively impacting the service life of the papermaking felt.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a papermaking blanket trimming device, including a mounting base, and a repair device is provided on one side of the mounting base, wherein the brush roller and the blade trim the side burrs of the papermaking blanket.

[0006] The effect achieved by the above components is as follows: when the paper machine is in production, the repair devices are installed on both sides of the papermaking blanket with the help of mounting bases. Then, when the paper machine is running, the repair devices are activated to clean and repair the rough edges and burrs on both sides of the papermaking blanket.

[0007] Preferably, the repair device includes a mounting plate, which is connected and assembled to one side of a mounting base by means of an adjusting device. Two mounting rods are rotatably arranged on the inner wall of the mounting plate. A brush roller is fixedly connected to the arc surface of the mounting rod, and meshing gears are fixedly connected to the arc surfaces of the two mounting rods respectively. A servo motor is fixedly connected to the surface of the mounting plate. The servo motor is connected to one of the mounting rods and rotates by means of a belt and a roller. Two blades are fixedly connected to the inner wall of the mounting base, and the two blades are inclined to each other.

[0008] The effects achieved by the above components are: when using papermaking felt, it is easier and more efficient to remove and repair burrs on the sides, and it is less likely to produce fraying, thus ensuring its normal use, not affecting the normal operation of the papermaking machine, and extending the service life of the papermaking felt.

[0009] Preferably, the repair device further includes two protective plates installed on the inner wall of the mounting plate, wherein the protective plates intercept and process the burrs and debris removed by the brush roller.

[0010] The effect achieved by the above components is that, by setting up the protective plate, when the brush roller removes the cut burrs on the side of the papermaking felt, the protective plate can prevent the burrs from flying off and causing secondary adhesion during the cleaning process.

[0011] Preferably, the repair device further includes a protective housing installed on one side of the servo motor, wherein the protective housing provides limiting protection for the belt on the roller.

[0012] The effect achieved by the above components is that, through the setting of the protective shell, the belt can be stably mounted on the roller at the output end of the servo motor, and it is not easy to slip off to the side, thus ensuring the normal operation of the device.

[0013] Preferably, a plurality of scrapers are installed on the arc surface of the brush roller, wherein the scrapers further treat the sides of the papermaking burrs.

[0014] The effect achieved by the above-mentioned components is as follows: by setting up scrapers made of metal, when the brush roller rotates to clean broken burrs, the scrapers can act as blades, rotating and removing residual lint from the sides, further improving the effectiveness of the repair device.

[0015] Preferably, the adjusting device includes a mounting tube, wherein the mounting tube is fixedly connected to the surface of the mounting plate, a connecting rod is slidably provided on the inner wall of the mounting tube, one end of the connecting rod is fixedly connected to the surface of the mounting base, and a bolt is threaded through the arc surface of the mounting tube, wherein one end of the bolt abuts against the surface of the connecting rod.

[0016] The effect achieved by the above components is that the repair device can be better adjusted in position during use, thereby adapting to the use of papermaking felt trimming, and improving the effectiveness and adaptability of the repair device.

[0017] Preferably, a reinforcing plate is fixedly connected to one side surface of the connecting rod, wherein the reinforcing plate enhances the limiting effect of the bolt.

[0018] The effect achieved by the above components is that by setting up a rubber reinforcing plate, the bolts are pressed against the surface of the reinforcing plate, which further increases the friction of the compression limit, thereby better maintaining the stability of the combined length of the connecting rod and the mounting tube.

[0019] Preferably, a sliding plate is installed on both sides of the surface of the connecting rod, and a sliding groove is opened on both sides of the surface of the mounting tube, wherein the sliding plate is slidably connected to the inner wall of the sliding groove.

[0020] The effect achieved by the above components is that, through the sliding arrangement of the slide plate and the slide groove, the mounting tube and connecting rod are more stable and less prone to shaking when sliding to adjust the combined length, thereby allowing for more precise adjustment and setting of the position of the repair device.

These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it 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.

[0031] Figure 1 and Figure 2 The papermaking felt trimming device shown includes a mounting base 1, and a repair device 2 is provided on one side of the mounting base 1. The brush roller 23 and the blade 28 trim the side burrs of the papermaking felt. The repair device 2 includes a mounting plate 21, which is connected and assembled to one side of the mounting base 1 by means of an adjusting device 3.

[0032] Figure 1 , Figure 2 and Figure 3 The inner wall of the mounting plate 21 shown has two mounting rods rotatably mounted. Brush rollers 23 are fixedly connected to the arc surface of each mounting rod 22, and meshing gears 27 are fixedly connected to the arc surfaces of the two mounting rods 22 respectively. A servo motor 24 is fixedly connected to the surface of the mounting plate 21. The servo motor 24 is connected to one mounting rod 22 via a sliding connection of a belt 26 and a roller 25. Two blades 28 are fixedly connected to the inner wall of the mounting base 1, and the two blades 28 are inclined relative to each other. When the paper machine is in production, repair devices 2 are installed on both sides of the papermaking blanket via the mounting base 1, so that the brush rollers 23 on the two mounting rods 22 and the two blades 28 on the mounting plate 21 clamp the papermaking blanket in the middle position. Then, when the paper machine is running, the papermaking process... When the papermaking blanket is in operation, its two sides come into contact with the cutting edges of the two blades 28, thereby cutting off the burrs and rough edges. At the same time, the servo motor 24 on the mounting plate 21 is activated, which drives the roller 25 to rotate. Then, the mixing roller 25 drives the belt 26 to run, causing one of the mounting rods 22 to rotate. Since the two mounting rods 22 are connected by gear 27, the two brush rollers 23 will simultaneously rotate and rub against the sides of the papermaking blanket, removing the burrs and impurities that have been removed by the blades 28 and are attached to its surface. At this time, the papermaking blanket can more conveniently and efficiently remove and repair the burrs on the sides, and is less likely to produce fraying, thus ensuring its normal use, not affecting the normal operation of the papermaking machine, and extending the service life of the papermaking blanket.

[0033] Figure 1 , Figure 2 and Figure 3The repair device 2 shown also includes two protective plates 211 installed on the inner wall of the mounting plate 21. The protective plates 211 intercept the burrs and debris removed by the brush roller 23. By setting the protective plates 211, when the brush roller 23 removes the burrs cut off on the side of the papermaking felt, the protective plates 211 can block the burrs from flying and re-attaching during cleaning. The repair device 2 also includes a protective shell 210 installed on one side of the servo motor 24. The protective shell 210 limits the belt 26 on the roller 25. The protective shell 210 ensures that the belt 26 can be stably mounted on the roller 25 at the output end of the servo motor 24, preventing lateral deviation and ensuring the normal operation of the device. Several scrapers 29 are installed on the arc surface of the brush roller 23. The scrapers further treat the sides of the papermaking burrs. With the scrapers 29 made of metal, when the brush roller 23 rotates to clean the broken burrs, the scrapers 29 can act as blades 28, rotating and removing the residual lint on the sides, further improving the effectiveness of the repair device 2.

[0034] Figure 1 , Figure 2 and Figure 4 The adjustment device 3 shown includes an installation tube 31, which is fixedly connected to the surface of the installation plate 21. A connecting rod 32 is slidably provided on the inner wall of the installation tube 31. One end of the connecting rod 32 is fixedly connected to the surface of the mounting base 1. A bolt 33 is threaded through the arc surface of the installation tube 31, and one end of the bolt 33 abuts against the surface of the connecting rod 32. After the repair device 2 is installed on the side of the papermaking blanket of the papermaking machine through the mounting base 1, the installation tube 31 is slid, so that the inner wall of the installation tube 31 slides on the surface of the connecting rod 32 until the blade 28 and other components on the inner wall of the mounting plate 21 are adjusted to the position suitable for use with the papermaking blanket. Then, the bolt 33 threaded on the surface of the installation tube 31 is rotated until one end of the bolt 33 contacts and presses against the surface of the connecting rod 32, so that the positions of the installation tube 31 and the mounting plate 21 are fixed. At this time, the repair device 2 can be better adjusted in position during use, thereby adapting to the use of papermaking blanket trimming, improving the use effect and adaptability of the repair device 2.

[0035] Figure 1 and Figure 4A reinforcing plate 35 is fixedly connected to one side surface of the connecting rod 32. The reinforcing plate 35 enhances the limiting effect of the bolt 33. The rubber reinforcing plate 35 increases the frictional force of the compression limit when the bolt 33 contacts and is pressed against the surface of the reinforcing plate 35, thereby better maintaining the stability of the combined length of the connecting rod 32 and the mounting tube 31. Slide plates 36 are installed on both sides of the surface of the connecting rod 32, and grooves 34 are opened on both sides of the surface of the mounting tube 31. The slide plates 36 are slidably connected to the inner walls of the grooves 34. The sliding arrangement of the slide plates 36 and the grooves 34 makes the mounting tube 31 and the connecting rod 32 more stable when sliding to adjust the combined length, and less prone to shaking, thereby more accurately adjusting and setting the position of the repair device 2.

[0036] Working principle: When the paper machine is in production, repair devices 2 are installed on both sides of the papermaking felt using mounting bases 1. The brush rollers 23 on the two mounting rods 22 and the two blades 28 on the mounting plate 21 clamp the papermaking felt in the middle. Then, as the papermaking felt rotates, its sides come into contact with the cutting edges of the two blades 28, cutting off the burrs and rough edges. Simultaneously, the servo motor 24 on the mounting plate 21 is activated, driving the rollers 25 to rotate. The mixing roller 25 drives the belt 26 to run, causing one of the mounting rods 22 to rotate. Since the two mounting rods 22 are connected by gear 27, the two brush rollers 23 will simultaneously rotate and rub against the side of the papermaking blanket, removing the burrs and impurities that have been removed by the blade 28 and are attached to its surface. At this time, when the papermaking blanket is in use, the side burrs can be removed and repaired more conveniently and efficiently, and it is less likely to produce fraying, thus ensuring its normal use, not affecting the normal operation of the papermaking machine, and extending the service life of the papermaking blanket.

[0037] After the repair device 2 is installed on the side of the papermaking felt of the papermaking machine via the mounting base 1, the mounting tube 31 is slid, causing the inner wall of the mounting tube 31 to slide on the surface of the connecting rod 32 until the blades 28 and other components on the inner wall of the mounting plate 21 are adjusted to the position suitable for use with the papermaking felt. Then, the bolts 33 threaded on the surface of the mounting tube 31 are rotated until one end of the bolt 33 contacts and presses against the surface of the connecting rod 32, fixing the position of the mounting tube 31 and the mounting plate 21. At this time, the repair device 2 can be better adjusted in position during use, thereby adapting to the use of papermaking felt trimming and improving the use effect and adaptability of the repair device 2.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
