Description

Technical Field

[0001] The present invention relates to the field of raw stone conveying equipment, and in particular to an automatic conveying device and method for stone processing. Background Art

[0002] Stone is a building material made after cutting, polishing, grinding and other processing techniques. Common stone materials include marble, granite, limestone, etc. The raw stone blocks are generally cut into plates of different sizes after being formed on the processing machine. In traditional technology, conveyor rollers or conveyor belts are mostly used to convey raw stone blocks. However, since the conveyor belt needs support, when facing large-volume raw stone blocks, due to the gravity of the raw stone blocks, the friction between the conveyor belt and the supporting components is greatly increased, resulting in poor conveying effect. At the same time, it poses a great challenge to the service life of the conveyor belt. When the conveyor roller is used for conveying, since the bottom of the raw stone blocks is often not very smooth, it often causes the bottom of the raw stone blocks to collide with the conveyor roller. At the same time, when facing high-density raw stone blocks, the driving force of the conveyor roller is often relatively lacking. Therefore, we propose an automatic conveying device and method for stone processing to solve the above-mentioned problems. Summary of the invention

[0005] Preferably, the support roller is provided with evenly distributed limiting grooves on its periphery, and the support roller is slidably connected with evenly distributed sliders on its periphery through the limiting grooves, and the sliders are threadedly connected to a threaded rod, and the threaded rod is provided with multiple symmetrical threads on its periphery, and the threads correspond to the sliders.

[0006] Preferably, the outer periphery of the slider is rotatably connected to a swivel sleeve via a bearing ball, the outer periphery of the swivel sleeve is fixedly connected to evenly distributed limit strips, the outer periphery of the swivel sleeve is provided with an outer protective sleeve, the outer periphery of the outer protective sleeve is provided with evenly distributed anti-slip patterns, and the swivel sleeve is clamped with the outer protective sleeve via the limit strips.

[0007] Preferably, both sides of the top of the frame are fixedly connected with a fixing frame 1, the outer periphery of the fixing frame 1 is sleeved with a conveyor belt, the lower and middle parts of the outer periphery of the conveyor belt are evenly installed with rotating seats, and the rotating parts of the rotating seats are fixedly connected with limiting frames.

[0008] Preferably, a servo motor is installed on the top of the limit frame, and the driving end of the servo motor is fixedly connected with a second threaded rod, and the second threaded rod is arranged inside the limit frame, and the outer periphery of the limit frame is provided with symmetrical threads.

[0009] Preferably, the upper and lower parts of the two outer circumferences of the threaded rod are threadedly connected with connecting blocks, the connecting blocks are slidably connected inside the limiting frame, the ends of the connecting blocks are rotatably connected with scissors frames, and the upper and lower ends of the scissors frames away from the connecting blocks are rotatably connected.

[0010] Preferably, the middle part of the end of the scissors frame is slidably connected to a limiting block, the limiting block is fixedly connected to the middle part of one side of the second fixing frame, and the other side of the second fixing frame is installed with a stop block.

[0011] Preferably, an opening two is provided in the middle of the stop block, an infrared sensor two is arranged inside the opening two, the infrared sensor two is installed in the middle of one end of the fixing frame two away from the limit block, and the infrared sensor two is electrically connected to the servo motor.

[0013] Preferably, an automated conveying method for stone processing comprises the following conveying steps:

[0014] S1. Place the raw stone block on the upper part of the raw stone conveyor through the lifting mechanism. When the raw stone block moves to the top of the rack, the infrared sensor on the inner bottom plate of the rack senses the raw stone block above. At this time, the hydraulic cylinder on one side will be activated by the raw stone block. The support roller will be lifted and lowered as a whole through the extension and contraction of the hydraulic cylinder. After the support roller rises, it will be flush with the first support roller set high at the inlet end, and jointly support the bottom of the raw stone block;

[0015] S2. When in use, the reduction motor is started, and the threaded rod 1 is driven to rotate by the reduction motor. When the threaded rod 1 rotates, the multiple sections of threads on the outer periphery of the threaded rod 1 drive the sliders on the outer periphery of the threaded rod 1 to move closer or farther, so as to adjust the distance between the sliders and make the sliders adapt to the original stones of different widths.

[0016] S3. During transportation, the second infrared sensor detects the original stone, starts the servo motor, drives the second threaded rod to rotate, and drives the upper and lower connecting blocks to move closer or farther away through the threads on the outer periphery of the second threaded rod, which causes the scissor frame to open and close, so that the second fixed frame and the stop block approach the original stone, and the original stone is stopped by the stop blocks on both sides;

[0017] S4, start the driving roller at one end of the fixed frame to drive the conveyor belt to rotate. When the conveyor belt rotates, the anti-bias clamping component will be used to pull the raw stone block, so that the raw stone block moves on the raw stone conveyor, completing the transportation of the raw stone block.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] When the raw stone moves to the top of the frame, the infrared sensor on the inner bottom plate of the frame can sense the raw stone above. At this time, the hydraulic cylinder on one side will be activated by the raw stone, and the extension and contraction of the hydraulic cylinder can drive the supporting roller to rise and fall as a whole. After the supporting roller rises, it will be flush with the first supporting roller set high at the inlet end, and jointly support the bottom of the raw stone to facilitate subsequent transportation. By making the supporting roller usually in a low position, the raw stone will not directly hit the next supporting roller when moving forward. By making the supporting roller contact with the bottom of the raw stone from bottom to top, the supporting roller can be less damaged during use, which is beneficial to prolonging the service life of the supporting roller.

[0020] When in use, the reduction motor can drive the threaded rod 1 to rotate. When the threaded rod 1 rotates, the multiple threads on the outer periphery of the threaded rod 1 drive the sliders on the outer periphery of the threaded rod 1 to move closer or farther away, thereby adjusting the distance between the sliders. This allows the sliders to adapt to raw stones of different widths, so that when facing raw stones of different widths, the threaded rod 1 and the sliders can be subjected to more uniform force, which is beneficial to actual use.

[0021] During transportation, the original stone block can be monitored by the second infrared sensor, thereby starting the servo motor, which can drive the second threaded rod to rotate, and the threads on the outer periphery of the second threaded rod can drive the upper and lower connecting blocks to move closer or farther away, thereby causing the scissors frame to open and close, so that the second fixed frame and the support block can move closer to the original stone block, and the original stone block can be supported by the support blocks on both sides to prevent the original stone block from deviating, thereby preventing the original stone block from shifting due to unstable center of gravity during transportation, which is beneficial to actual use.

[0022] When the conveyor belt rotates, the anti-bias clamping components will be used to pull the raw stone blocks, so that the raw stone blocks can be moved on the raw stone conveyor, thereby avoiding the problem that the driving force of the conveyor roller is often insufficient and the motor is easily overloaded when facing high-density raw stones. This is beneficial to practical use, and the bearing balls between the bottom plate and the slider can facilitate the rotation between the rotating sleeve and the slider, thereby facilitating the transportation of raw stones.

[0023] When encountering a raw stone block with a larger or smaller thickness, infrared sensor 1 detects the raw stone block, but infrared sensor 2 does not detect the raw stone block, the rotating seat will drive the limit frame to deflect as a whole, so as to adjust the height of infrared sensor 2, so that infrared sensor 2 can monitor the raw stone block, and further realize the anti-deflection and traction of the raw stone block.

The support rollers 107 are provided with threaded rods 117 inside, and the threaded rods 117 are fixedly connected to the driving end of the reduction motor 119. The reduction motors 119 are installed inside the side bin 114. The support rollers 107 are provided with bottom plates 112 on one side of the lower part, and the bottom plates 112 are installed at the lower inner part of the frame 101.

By making the support roller 107 usually in a low position, the raw stone 102 will not directly hit the next support roller 107 when moving forward. By making the support roller 107 contact with the bottom of the raw stone 102 from bottom to top, the support roller 107 can be less damaged during use, which is beneficial to improving the service life of the support roller 107.

[0037] Among them, the outer circumference of the support roller 107 is provided with uniformly distributed limiting grooves 111, and the outer circumference of the support roller 107 is slidably connected with uniformly distributed sliders 118 through the limiting grooves 111. The sliders 118 are threadedly connected with the threaded rod 117. The outer circumference of the threaded rod 117 is provided with multiple sections of symmetrical threads, and the threads correspond to the sliders 118. The outer circumference of the slider 118 is rotatably connected with a rotating sleeve 122 through a bearing ball, and the outer circumference of the rotating sleeve 122 is fixedly connected with uniformly distributed limiting strips 123.

[0038] Furthermore, in a specific implementation, the threaded rod 117 can be driven to rotate through the operation of the reduction motor 119. When the threaded rod 117 rotates, the multiple threads on the outer periphery of the threaded rod 117 drive the sliders 118 on the outer periphery of the threaded rod 117 to move closer or farther away, thereby adjusting the distance between the sliders 118, so that the sliders 118 can adapt to raw stone blocks 102 of different widths, so that when facing raw stone blocks 102 of different widths, the threaded rod 117 and the sliders 118 can be more evenly stressed, which is beneficial to actual use. The bearing balls between the bottom plate 112 and the sliders 118 can facilitate the rotation between the swivel sleeve 122 and the sliders 118, thereby facilitating the transportation of the raw stone blocks 102.

[0040] Furthermore, in a specific implementation, the driving roller at the end of the fixed frame 103 can drive the conveyor belt 104 to rotate. When the conveyor belt 104 rotates, the anti-bias clamping component will be used to pull the raw stone block 102, so that the raw stone block 102 can be moved on the raw stone conveyor 1, thereby avoiding the problem that the driving force of the conveyor roller is often insufficient and the motor is easily overloaded when facing high-density raw stones, which is beneficial to practical use. In actual use, when encountering raw stones 102 with lower or higher thickness, the infrared sensor 116 detects the raw stone block 102, while the infrared sensor 2 131 does not detect the raw stone block 102, the rotating seat 126 will drive the limit frame 109 to deflect as a whole, so as to adjust the height of the infrared sensor 2 131, so that the infrared sensor 2 131 can monitor the raw stone block 102, and further realize the anti-bias and traction of the raw stone block 102.

[0041] Among them, the middle part of the end of the scissor frame 105 is slidably connected to the limit block 128, the limit block 128 is fixedly connected to the middle part of one side of the second fixing frame 129, the other side of the second fixing frame 129 is installed with a stop block 110, the middle part of the stop block 110 is opened with an opening 127, and the inside of the opening 127 is provided with an infrared sensor 131, the infrared sensor 131 is installed in the middle part of one end of the second fixing frame 129 away from the limit block 128, and the infrared sensor 131 is electrically connected to the servo motor 106;

[0042] Furthermore, in a specific implementation, during transportation, the original stone block 102 can be monitored by the second infrared sensor 131, thereby starting the servo motor 106, and the second threaded rod 125 can be driven to rotate by the servo motor 106, and the upper and lower connecting blocks 130 can be driven to move closer or farther away by the threads on the outer periphery of the second threaded rod 125, thereby causing the scissors frame 105 to open and close, so that the second fixed frame 129 and the stop block 110 can be moved closer to the original stone block 102, and the original stone block 102 can be stopped by the stop blocks 110 on both sides, thereby preventing the original stone block 102 from deviating, and avoiding the original stone block 102 from shifting due to the unstable center of gravity during transportation, which is beneficial to actual use.

[0043] Among them, an automated conveying method for stone processing includes the following conveying steps:

[0044] S1, placing the raw stone 102 on the upper part of the raw stone conveyor 1 through the lifting mechanism, when the raw stone 102 moves to the top of the frame 101, the infrared sensor 116 on the inner bottom plate 112 of the frame 101 senses the raw stone 102 above, and at this time, the hydraulic cylinder 120 on one side is activated by the raw stone 102, and the support roller 107 is driven to rise and fall as a whole through the extension and contraction of the hydraulic cylinder 120. After the support roller 107 rises, it will be flush with the first support roller 107 set high at the inlet end, and jointly support the bottom of the raw stone 102;

[0045] S2, when in use, the reduction motor 119 is started, and the threaded rod 117 is driven to rotate by the reduction motor 119. When the threaded rod 117 rotates, the multiple sections of threads on the outer periphery of the threaded rod 117 drive the sliders 118 on the outer periphery of the threaded rod 117 to move closer or farther, so as to adjust the distance between the sliders 118, so that the sliders 118 can adapt to the original stones 102 of different widths;

[0046] S3. During transportation, the original stone 102 is detected by the second infrared sensor 131, and the servo motor 106 is started. The second threaded rod 125 is driven to rotate by the servo motor 106, and the upper and lower connecting blocks 130 are driven to move closer or farther by the threads on the outer periphery of the second threaded rod 125, so that the scissor frame 105 is opened and closed, and the second fixed frame 129 and the stop block 110 are moved closer to the original stone 102, and the original stone 102 is stopped by the stop blocks 110 on both sides;

[0047] S4, start the driving roller at the end of the fixed frame 103 to drive the conveyor belt 104 to rotate. When the conveyor belt 104 rotates, the anti-bias clamping component will be used to pull the original stone block 102, so that the original stone block 102 moves on the original stone conveyor 1, completing the transportation of the original stone block 102.

[0048] Working principle:

[0049] In actual use, people can place the raw stone 102 on the upper part of the raw stone conveyor 1 through the lifting mechanism. When the raw stone 102 moves to the top of the frame 101, the infrared sensor 116 on the inner bottom plate 112 of the frame 101 can sense the raw stone 102 above. At this time, the hydraulic cylinder 120 on one side will be activated by the raw stone 102. The extension and contraction of the hydraulic cylinder 120 can drive the supporting roller 107 to rise and fall as a whole. After the supporting roller 107 rises, it will be flush with the first supporting roller 107 set high at the inlet end, and jointly support the bottom of the raw stone 102 to facilitate subsequent transportation. By making the supporting roller 107 usually in a low position, the raw stone 102 can be moved forward. When the support roller 107 is in use, it will not directly hit the next support roller 107. By making the support roller 107 contact with the bottom of the original stone block 102 from bottom to top, the support roller 107 can be less damaged when in use, which is beneficial to prolonging the service life of the support roller 107. When in use, the threaded rod 117 can be driven to rotate through the work of the reduction motor 119. When the threaded rod 117 rotates, the multiple sections of threads on the outer periphery of the threaded rod 117 drive the sliders 118 on the outer periphery of the threaded rod 117 to move closer or farther, so as to adjust the distance between the sliders 118, so that the sliders 118 can adapt to the original stones 102 of different widths, so that when facing original stones of different widths, When the block 102 is moved, the threaded rod 117 and the slider 118 can be more evenly stressed, which is beneficial to practical use. At the same time, the bearing ball between the bottom plate 112 and the slider 118 can facilitate the rotation between the rotating sleeve 122 and the slider 118, so as to facilitate the transportation of the original stone block 102. During transportation, the original stone block 102 can be monitored by the infrared sensor 131, so as to start the servo motor 106, and the threaded rod 125 can be driven to rotate by the servo motor 106. The threads on the outer periphery of the threaded rod 125 can drive the upper and lower connecting blocks 130 to move closer or farther, so as to open and close the scissors frame 105, so as to enable the fixed frame 106 to move. 129 and the stop block 110 are close to the original stone block 102, and the original stone block 102 can be stopped by the stop blocks 110 on both sides to achieve anti-deviation of the original stone block 102, and avoid the original stone block 102 from shifting due to the unstable center of gravity during transportation, which is beneficial to practical use. At the same time, the driving roller at the end of the fixed frame 103 can drive the conveyor belt 104 to rotate. When the conveyor belt 104 rotates, the anti-deviation clamping component will be used to pull the original stone block 102, so that the original stone block 102 can be moved on the original stone conveyor 1, thereby avoiding the problem that the driving force of the conveyor roller is often insufficient and the motor is easily overloaded when facing high-density original stones, which is beneficial to practical use.
