Description

Technical Field

[0001] The invention relates to the technical field of belt conveyor accessories, and in particular to an automatic deviation-correcting mechanism for an automated conveyor belt. Background Art

[0002] Automated conveyor belts are an indispensable part of the mechanization and automation of material handling systems. When in use, automated conveyor belts are prone to deviation due to factors such as material impact and uneven belt tension. At this time, by setting up an automatic deviation correction device, the belt can be adjusted according to the direction and degree of belt deviation, so that the belt always maintains the correct position, thereby ensuring normal material transportation and production efficiency.

[0003] When the existing automatic deviation-correcting mechanism is in use, when the conveyor belt deviates, the tapered roller on the offset side will contact the conveyor belt due to the different diameters at both ends of the tapered roller. Due to the different linear speeds of the large and small ends of the roller in contact with the conveyor belt, a speed difference will be generated, thereby changing the force condition of the roller. At this time, the tapered roller rotates on the support frame and applies a lateral thrust to the conveyor belt. This thrust will cause the conveyor belt to return to the center line, achieving the effect of deviation correction.

[0004] When the material is unevenly distributed on the conveyor belt and deviates toward the tapered roller, it will produce uneven pressure on the conveyor belt, causing the conveyor belt to deviate during operation. The tapered roller needs to constantly adjust its position to correct this deviation, causing the conveyor belt to produce greater fluctuations or jitters during the deviation correction process, resulting in material scattering, thereby causing a decrease in conveying efficiency;

[0005] In addition, the material may adhere to the surface of the tapered roller during transportation. The adhered material will change the material and roughness of the roller surface, thereby affecting the friction coefficient between it and the conveyor belt. When the friction coefficient decreases, the correcting force will be weakened accordingly, resulting in poor correction effect. Summary of the Invention

[0028] In summary, due to the adoption of the above-mentioned technology, the automatic deviation-correcting mechanism of an automated conveyor belt has the following beneficial effects:

[0029] 1. By providing a scraper and a movable frame, when the conveyor belt is conveying materials and the materials are accumulated on one side, the scraper is driven to reciprocate inside the fixed frame, and the scraper drives the tapered roller inside the movable frame to reciprocate, so that the tapered roller drives the conveyor belt to reciprocate up and down, causing the tapered roller to shake, and the materials on the accumulated side of the conveyor belt can be moved to the middle of the conveyor belt. By providing a scraper, this device can drive the tapered roller to reciprocate, so that the materials are moved closer to the center of the conveyor belt, which can avoid the problems of conveyor belt fluctuation and shaking caused by uneven material distribution, thereby improving the stability and conveying efficiency of the conveyor belt. At the same time, the cleaning effect of the scraper on the surface of the tapered roller can ensure the stability of the friction coefficient between it and the conveyor belt, thereby maintaining the stability of the deviation correction.

[0030] 2. By providing a scraper, when the conical roller is used outdoors and ice adheres to its surface, the movable frame and the fixed frame can be limited and fixed, and the scraper can be driven to reciprocate inside the fixed frame. The scraper can crush the ice on the surface of the conical roller. This device can crush the ice on the surface of the conical roller through the scraper, avoiding the problem that ice adheres to the surface of the conical roller when it is used outdoors, and the ice layer causes the friction coefficient between the conical roller and the conveyor belt to change, thereby weakening the correcting force.

[0031] 3. By providing a baffle, when the piston plate reciprocates up and down inside the fixed frame, the air flow enters through the air inlet one-way valve and is discharged into the electric heating box through the exhaust one-way valve. The electric heating box heats the air flow and transmits it to the inside of the scraper. At this time, the baffle opens one side of the scraper and forms an exhaust channel, so that the hot air passes through the baffle and blows to the surface of the tapered roller, which can accelerate the melting of the ice layer on the surface of the tapered roller.

[0045] The following will be combined with the accompanying drawings to clearly and completely describe the technology in the embodiments of the present invention, an automatic deviation-correcting mechanism for an automated conveyor belt. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0046] like Figures 1-11As shown, the present invention provides: an automatic deviation-correcting mechanism for an automated conveyor belt, comprising a mounting frame 1, a rotating frame 2 being rotatably connected to the mounting frame 1, a first bidirectional screw rod 21 being rotatably connected inside the rotating frame 2, a moving block 22 being threadedly connected to the first bidirectional screw rod 21, a first connecting rod 23 being rotatably connected above the moving block 22, one end of the first connecting rod 23 being rotatably connected to a fixed plate 3, the fixed plate 3 being rotatably connected to the upper surface of the rotating frame 2, a supporting roller 5 being rotatably connected to the rotating frame 2, and a deviation-correcting mechanism being provided on the upper surface of the fixed plate 3;

[0047] The correction mechanism includes a fixed frame 31 fixedly connected to the fixed plate 3, a scraper 6 is slidably connected to the interior of the fixed frame 31, a limit rod 64 is slidably connected to the interior of the scraper 6, one end of the limit rod 64 is slidably connected to a movable frame 7, the movable frame 7 is slidably connected to the fixed plate 3, and a tapered roller 4 is rotatably connected to the interior of the movable frame 7;

[0048] The scraper 6 is driven to move back and forth, and the scraper 6 can drive the rotating frame 2 to move synchronously through the limit rod 64. The rotating frame 2 drives the conical roller 4 to move back and forth, and the conical roller 4 can shake the material on the conveyor belt so that the material is transported to the center of the conveyor belt. At the same time, the scraper 6 and the conical roller 4 are in contact, and the scraper 6 can clean the surface of the conical roller 4.

[0049] Specifically, when the conveyor belt is conveying, an automatic deviation-correcting mechanism is generally provided under the conveyor belt to prevent the conveyor belt from deviating. The existing automatic deviation-correcting mechanism is generally composed of tapered rollers, transverse rollers and a support frame. When the conveyor belt deviates, due to the different diameters at both ends of the tapered roller, the tapered roller on the offset side will contact the conveyor belt. Due to the different linear speeds of the contact points between the large and small ends of the rollers and the conveyor belt, a speed difference will be generated, thereby changing the force condition of the rollers. At this time, the tapered rollers rotate on the support frame and apply a transverse thrust to the conveyor belt. This thrust will cause the conveyor belt to return to the center line, thereby achieving the deviation-correcting effect.

[0050] When the material is unevenly distributed on the conveyor belt and deviates toward the tapered roller 4, uneven pressure will be generated on the conveyor belt, causing the conveyor belt to deviate during operation. The tapered roller needs to constantly adjust its position to correct this deviation, causing the conveyor belt to produce greater fluctuations or jitters during the deviation correction process, resulting in material scattering, thereby causing a decrease in conveying efficiency.

[0051] In addition, the material may adhere to the surface of the tapered roller during transportation. The adhered material will change the material and roughness of the roller surface, thereby affecting the friction coefficient between it and the conveyor belt. When the friction coefficient decreases, the correcting force will be weakened accordingly, resulting in poor correction effect.

[0052] The first bidirectional screw rod 21 is driven by the first bidirectional screw rod 21 to drive the moving block 22 to slide inside the rotating frame 2, and the moving block 22 drives the first connecting rod 23 to rotate. The first connecting rod 23 drives the fixed plate 3 to rotate on the mounting frame 1, and the fixed plate 3 drives the tapered roller 4 to move synchronously, so that the tapered roller 4 and the supporting roller 5 are all in contact with the bottom of the conveyor belt. When the conveyor belt deviates during transportation, the tapered roller 4 on the offset side will contact the conveyor belt. Due to the different linear speeds of the contact points between the roller and the conveyor belt, a speed difference will be generated, thereby changing the force condition of the tapered roller 4. At this time, the rotating frame 2 rotates on the mounting frame 1, so that the rotating frame 2 drives the tapered roller 4 to rotate, and the rotating tapered roller 4 applies a lateral thrust to the conveyor belt. This thrust will prompt the conveyor belt to return to the center line, thereby achieving the purpose of correcting the deviation.

[0053] When the material is unevenly distributed on the conveyor belt and deviates toward the tapered roller 4, the scraper 6 can be driven to reciprocate inside the fixed frame 31, and the scraper 6 drives the limit rod 64 to move synchronously. The limit rod 64 is inserted into the interior of the movable frame 7, so that when the scraper 6 reciprocates, it drives the movable frame 7 to slide back and forth on the fixed plate 3 through the limit rod 64, and the movable frame 7 drives the tapered roller 4 to slide back and forth. The tapered roller 4 exerts a reciprocating thrust on the conveyor belt, so that the conveyor belt can shake the material deviated to one side, so that the material moves closer to the center of the conveyor belt. At the same time, the scraper 6 maintains contact with the surface of the tapered roller 4. When the tapered roller 4 rotates, impurities attached to its surface will be cleaned by the scraper 6.

[0054] This device is provided with a scraper 6, which can drive the tapered roller 4 to reciprocate, so that the material is moved closer to the center of the conveyor belt, thereby avoiding the problem of conveyor belt fluctuation and jitter caused by uneven material distribution, thereby improving the stability and conveying efficiency of the conveyor belt. At the same time, the scraper 6 cleans the surface of the tapered roller 4 to ensure the stability of the friction coefficient between it and the conveyor belt, thereby maintaining the stability of the correction.

[0055] like Figure 3-Figure 5 As shown, the interior of the fixed frame 31 is rotatably connected to a turntable 32, one side of the turntable 32 is rotatably connected to a transmission plate 33, one end of the transmission plate 33 is rotatably connected to a piston plate 34, the piston plate 34 is slidably connected to the inner wall of the fixed frame 31, one side of the fixed frame 31 is fixedly connected to a first motor 35, one end of the first motor 35 is fixedly connected to the rotating end of the turntable 32, the interior of the scraper 6 is slidably connected to the upper surface of the piston plate 34, and a spring 341 is fixedly connected between the scraper 6 and the piston plate 34.

[0056] Specifically, turn on the first motor 35, the first motor 35 drives the turntable 32 to rotate, the turntable 32 drives the transmission plate 33 to rotate, the transmission plate 33 can drive the piston plate 34 to reciprocate up and down inside the fixed frame 31, the piston plate 34 can drive the scraper 6 installed above to reciprocate, the scraper 6 can drive the tapered roller 4 inside the movable frame 7 to reciprocate, and the material can be moved closer to the center of the conveyor belt.

[0057] like Figures 3 to 9 As shown, the scraper 6 is internally rotatably connected to a second bidirectional screw rod 61, and the surface of the second bidirectional screw rod 61 is threadedly connected to a movable plate 63, and the interior of the movable plate 63 is fixedly connected to one end of the limit rod 64, and a connecting hole 74 is provided on the movable frame 7, and the size of the connecting hole 74 matches that of the limit rod 64. One side of the scraper 6 is fixedly connected to a second motor 62, and the output end of the second motor 62 is fixedly connected to one end of the second bidirectional screw rod 61, and the interior of the movable frame 7 is fixedly connected to an elastic telescopic rod 71, and the movable end of the elastic telescopic rod 71 is fixedly connected to a top plate 72, and one end of the top plate 72 is fixedly connected to a fixed rod 73, and a fixing hole 310 is provided on the outer wall of the fixed frame 31, and the size of the fixing hole 310 matches that of the fixed rod 73.

[0058] Specifically, the second motor 62 is turned on, and the second motor 62 drives the second bidirectional screw 61 to rotate. The second bidirectional screw 61 drives the movable plate 63 to slide inside the scraper 6, and the scraper 6 drives the limiting rod 64 to move on the inner wall of the scraper 6. The limiting rod 64 enters the connecting hole 74 on one side of the movable frame 7. At this time, the limiting rod 64 contacts one side of the top plate 72, so that the top plate 72 is squeezed by the limiting rod 64 and slides inside the movable frame 7. The movable frame 7 slides and squeezes the elastic telescopic rod 71, and moves at the same time. When the cam 72 is in the closed position, the stopper 73 is in the closed position, and the stopper 73 is in the closed position, so that the stopper 73 is in the closed position, and the stopper 73 is in the closed position, so that the stopper 73 is in the closed position, and the stopper 73 is in the closed position, so that the stopper 73 is in the closed position, and the stopper 73 is in the closed position, so that the stopper 73 is in the closed position, and the stopper 73 is in the closed position, so that the stopper 73 is in the closed position, and the stopper 73 is in the closed position, so that the stopper 73 is in the closed position, and the stopper 73 is in the closed position, so that the stopper 73 is in the closed position, and the stopper 73 is in the closed position, so that the stopper 73

[0059] like Figures 9-11 As shown, a limiting plate 342 is fixedly connected to the piston plate 34, and a first limiting groove 343 is provided inside the limiting plate 342. A first sliding rod 65 is slidably connected inside the first limiting groove 343. The first sliding rod 65 and the limiting rod 64 are fixedly connected inside. The first limiting groove 343 includes a transverse section 3431, and a descending section 3432 is provided on one side of the transverse section 3431, and a fitting section 3433 is provided on one side of the descending section 3432.

[0060] Specifically, when the tapered roller 4 is used outdoors in snowy weather, snow will accumulate on the surface of the tapered roller 4. As the temperature fluctuates or the sun shines, some of the snow will melt into water. Since the external ambient temperature is low, the melted water will freeze into ice on the surface of the tapered roller 4, thus forming an ice layer. The presence of the ice layer will change the friction coefficient between the tapered roller 4 and the conveyor belt, thereby weakening the deviation-correcting force.

[0061] When the first slide bar 65 slides from the transverse section 3431 to the descending section 3432, the first slide bar 65 drives the limiting rod 64 to move downward. At this time, the spring 341 drives the scraper 6 to move downward, and the scraper 6 moves downward and away from the surface of the tapered roller 4. Subsequently, when the first slide bar 65 slides to the fitting section 3433, the lower part of the scraper 6 contacts the upper part of the piston plate 34. At this time, the piston plate 34 is driven to reciprocate inside the fixed frame 31. The piston plate 34 drives the limiting rod 64 through the limiting plate 342, and the limiting rod 64 drives the scraper 6 to reciprocate inside the fixed frame 31. Since one end of the scraper 6 is tapered, the scraper 6 can now break ice on the surface of the tapered roller 4.

[0062] The device can crush the ice layer on the surface of the conical roller 4 through the scraper 6, avoiding the problem that the ice layer adheres to the surface of the conical roller 4 when it is used outdoors, and the ice layer causes the friction coefficient between the conical roller 4 and the conveyor belt to change, thereby weakening the corrective force.

[0063] like Figures 9-11 As shown, the scraper 6 is internally rotatably connected to a cam 66, and the cam 66 is internally rotatably connected to a second connecting rod 67. One end of the second connecting rod 67 is rotatably connected to a moving rod 68. The moving rod 68 is internally slidably connected to the scraper 6, and one end of the moving rod 68 is rotatably connected to a third connecting rod 69. One end of the third connecting rod 69 is rotatably connected to a baffle 610. The baffle 610 is rotatably connected to the inner wall of the scraper 6. A second limiting groove 344 is provided inside the limiting plate 342, and a second sliding rod is internally slidably connected to the second limiting groove 344. One end of the second sliding rod is fixedly connected to one end of the cam 66. The second limiting groove 344 includes a closed section 3441, and an open section 3442 is provided on one side of the closed section 3441.

[0064] like Figure 3 and Figure 4As shown, an air intake one-way valve 39 is fixedly connected to the fixing frame 31, an exhaust one-way valve 36 is provided on the inner lower surface of the fixing frame 31, one end of the exhaust one-way valve 36 is fixedly connected to an electric heating box 37, and a connecting pipe 38 is fixedly connected between the electric heating box 37 and the scraper 6.

[0065] Specifically, when the ice layer is thick, it is difficult to quickly clean the ice layer by the reciprocating crushing operation of the scraper 6. The thicker ice layer will hinder the effective operation of the tapered roller 4 and reduce the correction effect.

[0066] In order to avoid the above problems, when the present device is in use, the electric heating box 37 can be opened. The electric heating box 37 is a prior art, and its exterior is a heat-insulating shell, and an electric heating wire is provided inside for heating treatment. When the piston plate 34 reciprocates inside the fixed frame 31, the piston plate 34 moves upward inside the fixed frame 31, and the air inlet check valve 39 opens, allowing external air to enter the interior of the fixed frame 31. When the piston plate 34 moves downward, the exhaust check valve 36 opens, allowing air to enter the interior of the electric heating box 37. After the gas is heated by the electric heating box 37, the heated gas is sent to the interior of the scraper 6 by the connecting pipe 38. As the scraper 6 moves downward and fits against the piston plate 34, a sealing area is formed between the piston plate 34 and the inner wall of the scraper 6. At the same time, when the scraper 6 moves downward During movement, the scraper 6 drives the cam 66 to move downward, and the second slide bar of the cam 66 slides in the second limit groove 344. When the scraper 6 moves downward, the second slide bar slides in the closed section 3441 of the second limit groove 344. At this time, the baffle 610 is in a closed state. When the second slide bar slides to the open section 3442, the second slide bar drives the cam 66 to rotate, and the cam 66 drives the second connecting rod 67 to rotate. The second connecting rod 67 pushes the moving rod 68 to move upward, and the moving rod 68 drives the third connecting rod 69 to rotate. The third connecting rod 69 pushes the baffle 610 to rotate. The baffle 610 rotates on one side of the scraper 6 and forms an exhaust channel aligned with the conical roller 4. At this time, the hot air blows toward the surface of the conical roller 4 through the exhaust channel formed by the baffle 610. The hot air can accelerate the melting of the ice layer on the surface of the conical roller 4.

[0067] Working principle: When using the device, the mounting frame 1 is fixedly installed on the bracket of the conveyor belt, and then the first bidirectional screw rod 21 is rotated. The first bidirectional screw rod 21 drives the moving block 22 to slide inside the rotating frame 2, and the moving block 22 drives the first connecting rod 23 to rotate. The first connecting rod 23 drives the fixed plate 3 to rotate on the mounting frame 1, and the fixed plate 3 drives the conical roller 4 to move synchronously, so that the conical roller 4 and the supporting roller 5 are all in contact with the bottom of the conveyor belt. When the conveyor belt deviates during transportation, the conical roller 4 on the offset side will contact the conveyor belt. Due to the different linear speeds of the contact points between the large and small heads of the rollers and the conveyor belt, a speed difference will be generated, thereby changing the force condition of the conical roller 4. At this time, the rotating frame 2 rotates on the mounting frame 1, so that the rotating frame 2 drives the conical roller 4 to rotate. The rotating conical roller 4 applies a lateral thrust to the conveyor belt. This thrust will prompt the conveyor belt to return to the center line, thereby achieving the purpose of correcting the deviation.

[0068] When the material is unevenly distributed on the conveyor belt and deviates to the conical roller 4, the second motor 62 is turned on, and the second motor 62 drives the second bidirectional screw 61 to rotate. The second bidirectional screw 61 drives the movable plate 63 to slide inside the scraper 6, and the scraper 6 drives the limiting rod 64 to move on the inner wall of the scraper 6, and the limiting rod 64 enters the connecting hole 74 on one side of the movable frame 7. At this time, the limiting rod 64 contacts one side of the top plate 72, so that the top plate 72 is squeezed by the limiting rod 64 and slides inside the movable frame 7. The movable frame 7 slides and squeezes the elastic telescopic rod 71. At the same time, the movable frame 7 drives the fixed rod 73 to slide toward the inside of the movable frame 7, so that the fixed rod 73 disengages from the fixed hole 310 on the outer wall of the fixed frame 31, and then opens. The first motor 35 drives the turntable 32 to rotate, and the turntable 32 drives the transmission plate 33 to rotate. The transmission plate 33 can drive the piston plate 34 to reciprocate up and down inside the fixed frame 31. The piston plate 34 drives the limit rod 64 to reciprocate downward through the limit plate 342. The limit rod 64 can drive the scraper 6 to reciprocate up and down. The scraper 6 drives the tapered roller 4 to slide back and forth through the limit rod 64. The tapered roller 4 exerts a reciprocating thrust on the conveyor belt, so that the conveyor belt can shake the material deviated to one side, so that the material approaches the center of the conveyor belt. At the same time, the scraper 6 maintains contact with the surface of the tapered roller 4. When the tapered roller 4 rotates, impurities attached to its surface will be cleaned by the scraper 6;

[0069] When the limiting rod 64 is separated from the connecting hole 74 and resets to the inside of the scraper 6, the elastic telescopic rod 71 drives the top plate 72 to reset, so that the top plate 72 drives the fixing rod 73 to enter the fixing hole 310, and the movable frame 7 and the fixed frame 31 are fixed. The limiting rod 64 drives the first slide bar 65 to move synchronously. At this time, the first slide bar 65 slides in the transverse section 3431 of the first limiting groove 343. When the first slide bar 65 slides from the transverse section 3431 to the descending section 3432, the first slide bar 65 drives the limiting rod 64 downward. Movement, at this time the spring 341 drives the scraper 6 to move downward, the scraper 6 moves downward and away from the surface of the tapered roller 4, and then when the first slide bar 65 slides to the fitting section 3433, the bottom of the scraper 6 contacts the top of the piston plate 34, and at this time the piston plate 34 is driven to reciprocate inside the fixed frame 31, and the piston plate 34 drives the limiting rod 64 through the limiting plate 342, and the limiting rod 64 drives the scraper 6 to reciprocate inside the fixed frame 31. Since one end of the scraper 6 is tapered, the scraper 6 can now break ice on the surface of the tapered roller 4;

[0070] When the piston plate 34 reciprocates inside the fixing frame 31, the piston plate 34 moves upward inside the fixing frame 31, and the air inlet check valve 39 opens, allowing external air to enter the inside of the fixing frame 31. When the piston plate 34 moves downward, the exhaust check valve 36 opens, allowing air to enter the inside of the electric heating box 37. After the air is heated by the electric heating box 37, the heated air is sent to the inside of the scraper 6 by the connecting pipe 38. As the scraper 6 moves downward and fits with the piston plate 34, a sealing area is formed between the inner wall of the piston plate 34 and the scraper 6. At the same time, when the scraper 6 moves downward, the scraper 6 drives the cam 66 to move downward, and the second slide rod of the cam 66 is in the second limit position. The second sliding rod slides in the groove 344. When the scraper 6 moves downward, the second sliding rod slides in the closed section 3441 of the second limiting groove 344. At this time, the baffle 610 is in a closed state. When the second sliding rod slides to the open section 3442, the second sliding rod drives the cam 66 to rotate. The cam 66 drives the second connecting rod 67 to rotate. The second connecting rod 67 pushes the moving rod 68 to move upward. The moving rod 68 drives the third connecting rod 69 to rotate. The third connecting rod 69 pushes the baffle 610 to rotate. The baffle 610 rotates on one side of the scraper 6 and forms an exhaust channel aligned with the conical roller 4. At this time, hot air is blown to the surface of the conical roller 4 through the exhaust channel formed by the baffle 610. The hot air can accelerate the melting of the ice layer on the surface of the conical roller 4.

[0071] After use, the limiting rod 64 is driven to enter the connecting hole 74, the scraper 6 and the tapered roller 4 are in contact with each other, and the baffle 610 is closed at the same time.
