Description

Technical Field

[0001] The present invention relates to the technical field of belt conveyor equipment, and particularly to a belt conveyor deviation rectifying device for transporting thermal insulation composite boards. Background Art

[0002] Plastic thermal insulation composite board is a building material composed of two or more materials through a specific process, integrating multiple functions such as heat preservation, heat insulation, fire prevention, moisture proof, and sound insulation. In the transportation process of plastic thermal insulation composite boards, belt conveyors play an important role. It mainly consists of components such as a conveyor belt, a driving device, rollers, idlers, a tensioning device, and a cleaning device. During operation, the driving device drives the rollers to rotate, and the rollers drive the conveyor belt to run by relying on friction, thereby realizing the transportation of plastic thermal insulation composite boards. However, in the conveying operation of belt conveyors, due to the long conveying distance of the conveyor belt and the frequent impacts caused by continuous material loading, the situation of the belt running off track on the rollers occurs frequently. Once it runs off track, problems such as wear, tearing, and even breakage are likely to occur at the edge of the conveyor belt. At this time, the deviation rectifying device is particularly crucial. It can effectively prevent the conveyor belt from being damaged due to running off track, thereby extending the service life of the conveyor belt and reducing the equipment operation cost.

[0003] Chinese Patent with Publication No. CN118753712B discloses a deviation rectifying device for a belt conveyor. Its structure includes a conveying frame and multiple conveyor belts. The inner side walls at both ends of the longer side of the conveying frame are rotatably connected with driving shafts. The outer side walls of the driving shafts are fixedly connected with transport rollers for driving the conveyor belt to drive. There are multiple deviation rectifying mechanisms between the two driving shafts. This solution can, by setting a deviation rectifying mechanism on the transmission track of the conveyor belt, when the conveyor belt deviates at a certain position, the conveyor belt will push the corresponding alignment plate. When the alignment plate moves into the downward moving section, the internal thread and the external thread will come into contact, and then the driving block will have the power for deviation rectification, and can push the position where the conveyor belt deviates to move towards the initial set direction, thereby playing a role in deviation rectification.

[0004] However, the above existing technology has the following deficiencies: When the conveyor belt deviates, the deviation rectifying device will generate a reverse thrust on the deviated side of the conveyor belt to correct the deviation. However, since the conveyor belt is a flexible material, under the action of the reverse thrust, wrinkles may occur on the deviated side of the conveyor belt, resulting in local stress concentration of the conveyor belt, accelerating the wear and aging of this part, shortening the overall service life of the conveyor belt. The wrinkles may also increase the running resistance of the conveyor belt, increasing the energy consumption of the equipment. If the wrinkle situation is serious, it will interfere with the normal operation of the idlers and rollers, and may even jam the conveyor belt, causing a shutdown failure, affecting the continuous and stable operation of the belt conveyor, and increasing the equipment maintenance cost and repair frequency. Summary of the Invention

[0005] The object of the present invention is to solve the problem that when the conveyor belt is offset, the deviation correction device will generate a reverse thrust on the offset side of the conveyor belt to correct the offset. However, since the conveyor belt is made of flexible material, under the action of the reverse thrust, wrinkles may occur on the offset side of the conveyor belt, resulting in local stress concentration of the conveyor belt, accelerating the wear and aging of this part, shortening the overall service life of the conveyor belt. The wrinkles may also increase the running resistance of the conveyor belt, increasing the energy consumption of the equipment. If the wrinkle situation is serious, it will interfere with the normal operation of the idlers and drums, and may even jam the conveyor belt, causing a shutdown fault, affecting the continuous and stable operation of the belt conveyor, and increasing the equipment maintenance cost and maintenance frequency.

A pulling member one is slidably connected in the cavity, and the pulling member one penetrates the cavity and the through groove. A pulling member two is slidably connected in the cavity, and the pulling member two penetrates the cavity and the through groove. The pulling member one and the pulling member two are rotationally symmetrically distributed. The cavity is provided with a ball group, and the ball group abuts against both sides of the pulling member one and the pulling member two respectively;

[0008] A limiting member is fixedly connected to the outer surface of the conveyor belt in the conveyor. One end of the pulling member one is fixedly connected with a connecting rod. A reaction block is fixedly connected to the outer circumferential surface of the connecting rod, and the reaction block is arranged inside the limiting member;

[0009] Wherein, when the conveyor belt in the conveyor is offset, the limiting member is synchronously offset until the limiting member pushes the reaction block in the pulling member one to move and transmits it to the ball group, so that the ball group pushes the pulling member two to move in the reverse direction, and the pulling member two exerts a reverse traction force on the conveyor belt in the conveyor.

[0010] As a further solution of the present invention: The limiting member is composed of two groups of limiting blocks. The reaction block is arranged between the two groups of limiting blocks, and two groups of limiting members are provided, which are symmetrically distributed on the outer surface of the conveyor belt in the conveyor.

[0011] As a further solution of the present invention: a connecting rod and a reaction block are also arranged on the second pulling member, and the reaction block on the second pulling member is arranged between two limiting blocks in another group of limiting members.

[0012] As a further solution of the present invention: a set of sliding beads are embedded on the corresponding surfaces of the reaction block and the two limiting blocks in the limiting member, and the sliding beads are rotatably connected to the reaction block.

[0013] As a further solution of the present invention: the first pulling member includes a push block arranged inside the cavity and slidably connected to the cavity. One end of the push block penetrates through the cavity and the through groove and is fixedly connected to a linkage block, and the linkage block is arranged inside the mounting block. A sliding block is fixedly connected to one side of the linkage block, and the sliding block is slidably connected to the through groove. The sliding block and the push block are symmetrically distributed on both sides of the linkage block.

[0014] As a further solution of the present invention: the second pulling member is also provided with a linkage block, a push block and a sliding block.

[0015] As a further solution of the present invention: the guiding device includes a fixing block fixedly connected to the end face of the connecting rod. A rotating rod is fixedly connected to the bottom end of the fixing block. The top end of the rotating rod penetrates through the fixing block and is fixedly connected to a locking block. The side end of the rotating rod is rotatably connected to a rotating cylinder, and the rotating cylinder is arranged below the fixing block. A driving member is arranged on the outer side of the rotating cylinder. A guiding cylinder is fixedly connected to the outer side of the rotating cylinder, and the guiding cylinder is sleeved on the outer side of the driving member.

[0016] As a further solution of the present invention: the driving member includes a housing fixedly connected to the outer cylindrical surface of the rotating cylinder. A linkage plate is slidably inserted into the bottom end of the housing. A guiding groove is formed in the side end of the housing. A guiding block is fixedly connected to the side end of the linkage plate, and the guiding block is slidably connected to the guiding groove.

[0017] As a further solution of the present invention: a push plate is fixedly connected to the outer side of the rotating rod. The push plate is arranged below the rotating cylinder, and the top end of the push plate abuts against the bottom end of the linkage plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In the present invention, an efficient control of the conveyor belt deviation is achieved through a correction device. When the conveyor belt deviates, the limit member moves along with the belt, squeezing the reaction block to trigger the action of the pulling member. The first pulling member and the second pulling member are in low-friction linkage through a ball group, converting the thrust on one side of the deviation into a balanced traction force on the other side, effectively avoiding wrinkles during the conveyor belt correction process. Multiple uniformly distributed correction devices form a global protection, quickly responding to local deviations and avoiding stress concentration. At the same time, the rolling design of the ball group reduces component wear, extends the equipment life, ensures the stable and smooth conveying process of the thermal insulation composite board, and reduces the risk of production interruption;

[0020] 2. The guiding device can effectively prevent the composite board deviation from exerting an additional force on the correction device. When the conveyor belt rotates, the surface of the conveyor belt contacts the linkage plate, driving the guiding cylinder to rotate, and gradually guiding the deviated composite board to the center line of the conveyor belt using the tangential friction force. This can reduce the shaking and deviation of the composite board during the conveying process, enabling the correction device to focus more on the belt deviation correction work, reducing the working burden of the correction device, and improving the stability and reliability of the entire deviation correction system;

[0021] 3. The guiding device reduces the running resistance and energy consumption. During the rotation process, the linkage plate will periodically disengage from and contact the conveyor belt due to the action of the push plate, always keeping half of the linkage plate in the contact driving state and the other half in the retracted state. This working mode not only ensures the continuous rotation of the guiding cylinder to apply the guiding force but also significantly reduces the contact area and time with the conveyor belt, reducing the friction force, thereby reducing the energy consumption of the equipment operation and extending the service life of the equipment.

The embodiments of the present invention will be described below according to its overall structure.

[0035] Referring to Figure 1 , in the embodiment of the present invention, a belt conveyor deviation correction device for the transportation of thermal insulation composite panels includes: a conveyor 1 for conveying the thermal insulation composite panels. A correction device 2 is provided on the conveyor 1 to limit the conveyor belt on the conveyor 1. When the conveyor belt deflects to one side, it pulls the other side to prevent its deviation. A plurality of groups of correction devices 2 are provided and evenly distributed on the conveyor 1. Two sets of guiding devices 3 are provided on each group of correction devices 2 to guide the composite panels conveyed on the conveyor 1 and prevent the composite panels from continuously applying additional forces to the correction device 2 during the conveying process. And the two sets of guiding devices 3 are symmetrically distributed.

[0036] Referring to Figures 1 to 5, the correction device 2 includes a connection block 22 fixedly connected to the fixed frame in the conveyor 1. The connection block 22 is concave-shaped, and there are two sets of connection blocks 22, symmetrically distributed on both sides inside the fixed frame in the conveyor 1. One end of the connection block 22 is fixedly connected to a mounting block 23. The mounting block 23 is O-shaped and is arranged between the two sets of connection blocks 22. Both ends of the mounting block 23 are fixedly connected to one set of connection blocks 22 respectively. The connection block 22 and the mounting block 23 are arranged inside the O-shaped conveyor belt in the conveyor 1. A cavity 24 is formed inside the mounting block 23, and a through groove 25 is formed inside the mounting block 23, and the through groove 25 communicates with the cavity 24. A pulling member one 26 is slidably connected inside the cavity 24, and the pulling member one 26 passes through the cavity 24 and the through groove 25. The pulling member one 26 includes a push block 262 arranged inside the cavity 24 and slidably connected to the cavity 24. The push block 262 is convex-shaped. One end of the push block 262 passes through the cavity 24 and the through groove 25 and is fixedly connected to a linkage block 261, and the linkage block 261 is arranged inside the O-shaped mounting block 23. A sliding block 263 is fixedly connected to one side of the linkage block 261, and the sliding block 263 is slidably connected to the through groove 25. The sliding block 263 and the push block 262 are symmetrically distributed on both sides of the linkage block 261. A pulling member two 27 is slidably connected inside the cavity 24, and the pulling member two 27 passes through the cavity 24 and the through groove 25. The pulling member one 26 and the pulling member two 27 are rotationally symmetrically distributed. The pulling member two 27 is also provided with a linkage block 261, a push block 262 and a sliding block 263. The cavity 24 is provided with a ball group 210. The ball group 210 is composed of multiple sets of mutually abutting steel balls. The diameter of the steel balls is smaller than the height of the through groove 25, and the ball group 210 abuts against both sides of the pulling member one 26 and the pulling member two 27 respectively. There are two sets of ball groups 210, and the two sets are distributed between the two push blocks 262 inside the O-shaped cavity 24. One end of the pulling member one 26 is fixedly connected to a connecting rod 28, and a reaction block 29 is fixedly connected to the outer circumferential surface of the connecting rod 28. The pulling member two 27 is also provided with a connecting rod 28 and a reaction block 29. One set of sliding beads 291 is embedded on both sides of each reaction block 29, and the sliding beads 291 are rotatably connected to the reaction block 29. The outer surface of the conveyor belt in the conveyor 1 is fixedly connected with a limiting member 21. The limiting member 21 is composed of two O-shaped annular belts, and there are two sets of limiting members 21, symmetrically distributed on the outer surface of the conveyor belt in the conveyor 1. Each reaction block 29 is arranged between the two annular belts of each limiting member 21, and the reaction block 29 on the pulling member two 27 is arranged between the two limiting blocks of the other set of limiting members 21. When the conveyor belt on the conveyor 1 conveys the thermal insulation composite board and is offset, the limiting member 21 fixed on the outer surface of the conveyor belt will move accordingly. Taking the conveyor belt offset to the right as an example, the two O-shaped annular belts of the right limiting member 21 will squeeze the reaction block 29 located therebetween. The sliding beads 291 on both sides of the reaction block 29 can reduce the friction with the annular belt. After being stressed, the reaction block 29 pushes the connecting rod 28, and then drives the pulling member one 26 on the right side to act. The linkage block 261 of the pulling member one 26 slides along the through groove 25 inside the mounting block 23.The convex-shaped push block 262 slides to the right in the cavity 24, squeezing the internal ball group 210. The ball group 210 is composed of dense steel balls. The steel balls roll under the thrust of the push block 262, transmitting the pressure to the symmetrically distributed pulling member two 27. After the pulling member two 27 is stressed, its linkage block 261 slides in the opposite direction, and the push block 262 displaces to the left in the cavity 24. Through the left connecting rod 28 and the reaction block 29, the left limiting member 21 is pulled to apply a leftward traction force to the conveyor belt. If the conveyor belt deflects to the left, the process is reversed. The left limiting member 21 drives the pulling member two 27, and the force is transmitted to the pulling member one 26 through the ball group 210 to apply a reverse pulling force to the right, thereby realizing the precise rectification of the conveyor belt.

[0037] Adopting the above solution: The rectification device 2 realizes the efficient and precise rectification of the conveyor belt deviation. It uses the ball group 210 to transmit force, reduces the friction between components, reduces energy loss, and prolongs the service life of the device. Multiple groups of evenly distributed rectification devices 2 can quickly trigger the rectification mechanism in the corresponding area regardless of where the conveyor belt deviates, maintaining the overall stable operation of the conveyor belt, greatly improving the reliability of the conveying process. At the same time, the symmetric design and dynamic balance principle of the device can effectively cope with deviations of different degrees and directions, enhancing the adaptability and versatility of the device, ensuring that the thermal insulation composite board always remains stable during transportation, reducing production accidents and material losses caused by conveyor belt deviation, and improving production efficiency and economic benefits.

[0038] Refer to Figures 5 to 10, the alignment device 3 includes a fixed block 31 fixedly connected to the end face of the connecting rod 28. At the bottom end of the fixed block 31, a rotating rod 32 is fixedly connected. There are three groups of rotating rods 32, which are evenly distributed at the bottom end of the fixed block 31. The top end of each group of rotating rods 32 penetrates through the fixed block 31 and is fixedly connected with a locking block 33. There are two groups on each group of rotating rods 32, symmetrically distributed at the upper and lower ends of the fixed block 31. One rotating cylinder 36 is rotatably connected to the side end of each group of rotating rods 32, and the rotating cylinder 36 is arranged below the fixed block 31. A driving member 35 is arranged on the outer side of the rotating cylinder 36. There are multiple groups of driving members 35, which are evenly distributed on the outer side of the rotating cylinder 36. One guiding cylinder 34 is fixedly connected to the outer side of each group of rotating cylinders 36, and the guiding cylinder 34 is sleeved on the outer side of the driving member 35. The driving member 35 includes a housing 351 fixedly connected to the outer cylindrical surface of the rotating cylinder 36. A linkage plate 352 is slidably inserted at the bottom end of the housing 351. One side of the bottom end of the linkage plate 352 is an arc surface. A guiding groove 354 is formed at the side end of the housing 351. There are two groups of guiding grooves 354, symmetrically distributed on both sides of the housing 351. Two guiding blocks 353 are fixedly connected to the side end of the linkage plate 352. The two guiding blocks 353 are symmetrically distributed on both sides of the linkage plate 352, and each group of guiding blocks 353 is slidably connected with a guiding groove 354. A spring 355 is fixedly connected to the top end of the linkage plate 352. One end of the spring 355 is fixedly connected to the top end inside the housing 351. There are three groups of each linkage plate 352, evenly distributed at the top end of the linkage plate 352. A push plate 37 is fixedly connected to the outer side of the rotating rod 32. The push plate 37 is arranged below the rotating cylinder 36. The push plate 37 is spirally wound around the outer side of the rotating rod 32, and the planar distance from the starting point to the ending point of the spiral-shaped push plate 37 is half of the circumference of the rotating rod 32. When the spring 355 extends, the bottom end of the linkage plate 352 abuts against the top surface of the conveyor belt on the conveyor 1, and the bottom end of the linkage plate 352 is lower than the bottom end of the rotating cylinder 36. The lowest point of the spiral-shaped push plate 37 is within the range of the arc surface at the bottom end of the linkage plate 352. During the conveying process of the thermal insulation composite board, the conveyor belt of the conveyor 1 continuously rotates. The linkage plate 352 in contact with the top surface of the conveyor belt starts to rotate around the rotating rod 32 under the drive of friction. The linkage plate 352 is fixedly connected to the housing 351, and its rotation drives the housing 351, thereby synchronously rotating the guiding cylinder 34 fixed to the outer side of the rotating cylinder 36. During the rotation of the three juxtaposed guiding cylinders 34, they will contact the edge of the offset composite board, and use the tangential friction force to gradually adjust the inclined composite board to the center line position of the conveyor belt to achieve the alignment function. During the rotation, when the linkage plate 352 moves to the spiral rising section of the spiral-shaped push plate 37, the inclined surface of the push plate 37 interacts with the arc surface at the bottom end of the linkage plate 352. The push plate 37 pushes the linkage plate 352 into the housing 351, compressing the spring 355, so that the linkage plate 352 temporarily disengages from the surface of the conveyor belt. As the rotating rod 32 continues to rotate, after the linkage plate 352 moves out of the action range of the push plate 37, the spring 355 releases its elastic force, pushing the linkage plate 352 to reset and making it abut against the conveyor belt again. Through this mechanism,When the multiple sets of driving members 35 rotate, half of the linkage plates 352 are always in contact with the conveyor belt in a driving state, and the other half are in a retracted state, ensuring that while the guiding cylinder 34 continuously rotates for guiding, the running resistance is effectively reduced.

[0039] Adopting the above solution: The guiding device 3 improves the accuracy and stability of the transportation of the thermal insulation composite board. It utilizes the power of the rotation of the conveyor belt to drive the guiding cylinder 34 to rotate through the linkage plate 352 and the driving member 35, without the need for an additional power source, reducing energy consumption and improving energy utilization efficiency. The three sets of parallel guiding cylinders 34 work together to quickly and effectively guide the offset composite board, reducing the damage caused by the collision of the composite board with the conveyor belt or other components due to offset, reducing material loss, and ensuring product quality. In addition, the periodic contact mechanism formed by the cooperation of the linkage plate 352 and the push plate 37 significantly reduces the frictional resistance during the operation of the device, reduces component wear, extends the service life of the equipment, and reduces the equipment maintenance cost. At the same time, the device can adapt to composite boards with different degrees of offset, enhancing the adaptability and versatility of the entire transportation system, effectively avoiding additional pressure on the correction device 2 due to the offset of the composite board, ensuring the stable and efficient operation of the entire belt conveyor system, and improving production efficiency and economic benefits.

[0040] The working principle of the present invention is: when the conveyor belt on the conveyor 1 deviates during the process of conveying the thermal insulation composite board, the limiting member 21 composed of two groups of symmetrical O-shaped ring belts fixed on the outer surface of the conveyor belt will move synchronously with the deviation direction. For example, if the conveyor belt deviates to the right, the two groups of ring belts of the right limiting member 21 will squeeze the reaction block 29 clamped therebetween. The reaction block 29 makes low-friction contact with the ring belt through the sliding beads 291 embedded on both sides, pushing the connecting rod 28 fixedly connected thereto, thereby driving the pulling member 26 on the right side to link. At this time, the linkage block 261 of the pulling member 26 slides along the through groove 25 on the inner side of the mounting block 23, and its convex push block 262 slides to the right in the cavity 24. The two groups of ball groups 210 composed of densely packed steel balls in the cavity 24 are squeezed. The steel balls roll under the push of the push block 262, and the pressure is efficiently transmitted to the symmetrically distributed pulling piece 27, forcing the left linkage block 261 to slide in the opposite direction. The push block 262 of the pulling piece 27 moves to the left in the cavity 24, and pulls the left limit piece 21 through the left connecting rod 28 and the reaction block 29, exerting a traction force to the left on the conveyor belt. The corrective forces on both sides are transmitted through the low friction of the ball group 210 to form a dynamic balance, forcing the conveyor belt to gradually reset. If the conveyor belt deviates to the left, the left limit piece 21 drives the pulling piece 27 through the same mechanism, and the ball group 210 transmits the force to the pulling piece 1 26, apply reverse pulling force to the right side to achieve precise deviation correction. Multiple groups of correction devices 2 are evenly distributed along the conveyor belt to form a deviation correction network covering the entire belt, ensuring that local deviation triggers symmetrical traction in the corresponding area to maintain the overall stability of the conveyor belt. At the same time, the continuous rotation of the conveyor belt drives the guiding device 3 to operate, and the surface of the conveyor belt contacts the bottom end of the linkage plate 352. The friction force drives the linkage plate 352 to rotate around the rotating rod 32, driving the shell 351 and the guiding cylinder 34 fixed to the outside of the rotating cylinder 36 to rotate synchronously. The three groups of parallel guiding cylinders 34 contact the edge of the composite plate through rotation, and use the tangential friction force to gradually guide the offset composite plate to the center line of the conveyor belt. During the rotation process, When a group of linkage plates 352 moves to the spiral ascending section of the push plate 37, the inclined surface of the push plate 37 contacts the arc surface at the bottom end of the linkage plate 352, pushing the linkage plate 352 into the shell 351, compressing the spring 355 to temporarily separate it from the surface of the conveyor belt. As the rotating rod 32 continues to rotate, the linkage plate 352 moves out of the action range of the push plate 37, and the spring 355 releases its elastic force, pushing the linkage plate 352 to reset and re-engage the conveyor belt. This mechanism ensures that when the multiple groups of driving members 35 rotate, half of the linkage plates 352 are always in a contact driving state and the other half are in a retracted state, which not only ensures that the guide cylinder 34 continues to rotate to apply the guide force, but also significantly reduces the running resistance by periodically disengaging from contact.The efficient control of the conveyor belt deviation is achieved through the correction device 2. When the conveyor belt deviates, the limit member 21 moves with the belt, squeezing the reaction block 29 to trigger the action of the pulling member. The first pulling member 26 and the second pulling member 27 are in low-friction linkage through the ball group 210, converting the thrust on the deviated side into the balanced traction force on the other side, effectively avoiding wrinkles during the conveyor belt correction process. Multiple evenly distributed correction devices 2 form a global protection, quickly responding to local deviations and avoiding stress concentration. At the same time, the rolling design of the ball group 210 reduces component wear, extends the equipment life, ensures the stable and smooth conveying process of the thermal insulation composite board, and reduces the risk of production interruption. The guiding device 3 can effectively prevent the composite board deviation from applying an additional force to the correction device 2. When the conveyor belt rotates, the surface of the conveyor belt contacts the linkage plate 352, driving the guiding cylinder 34 to rotate, and gradually guiding the deviated composite board to the center line of the conveyor belt by using the tangential friction force. This can reduce the shaking and deviation of the composite board during the conveying process, enabling the correction device 2 to focus more on the belt deviation correction work, reducing the working burden of the correction device 2, and improving the stability and reliability of the entire deviation correction system. The guiding device 3 reduces the running resistance and energy consumption. During the rotation process, the linkage plate 352 periodically detaches from and contacts the conveyor belt due to the action of the push plate 37, always keeping half of the linkage plate 352 in the contact driving state and the other half in the retracted state. This working mode not only ensures the continuous rotation of the guiding cylinder 34 to apply the guiding force, but also significantly reduces the contact area and time with the conveyor belt, reduces the friction force, thereby reducing the energy consumption of the equipment operation and extending the service life of the equipment.
