Description

Technical Field

[0001] This invention relates to the field of palletizing machinery technology, specifically to a mining palletizing machine with an adsorption-type feeding mechanism. Background Technology

[0002] In the mining industry, coal gangue bricks are a common auxiliary building material used in mines, and their stacking is a key process in subsequent storage and transportation.

[0003] The existing palletizing equipment relies heavily on manual calibration for its base frame placement, lacking automated positioning mechanisms. This makes the base frame prone to shifting, leading to tilting and collapse during subsequent coal gangue brick stacking, requiring repeated adjustments and reducing palletizing efficiency. The lateral drive of multi-digital palletizing equipment relies solely on a single screw or gear transmission structure. When the drive motor or transmission components fail, the equipment shuts down immediately, failing to provide emergency drive and severely impacting the continuous production rhythm of the mining industry. Existing equipment limits the position adjustment of coal gangue bricks to unidirectional movement, lacking multi-angle rotation and multi-dimensional position calibration. This makes precise alignment difficult when dealing with coal gangue bricks of different specifications and placement angles, resulting in poor palletizing compatibility. Furthermore, the lack of stable auxiliary support structures during adjustment makes it prone to adjustment deviations, affecting palletizing accuracy.

[0004] Therefore, we propose a mining palletizer with an adsorption feeding mechanism. Summary of the Invention

[0016] Compared with existing technologies, it has the following advantages:

[0017] 1. By setting up blocks, a central positioning frame, and positioning servo cylinders inside the movable palletizing machine frame, when the palletizing base frame is placed, the blocks first achieve initial positioning, and then the positioning servo cylinders on both sides drive the front and rear central positioning frames to clamp and position the palletizing base frame, ensuring that the palletizing base frame is stably located in the center inside the movable palletizing machine frame, avoiding errors from manual calibration, providing a stable foundation for the subsequent precise palletizing of coal gangue bricks, and reducing the risk of pallet tilting and collapse.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0033] Please see Figures 1 to 10 As shown, a mining palletizer with an adsorption-type feeding mechanism includes: a movable palletizer frame 1 and a palletizer base 2. The movable palletizer frame 1 has casters on both sides of its bottom for flexible movement. A stop block 6 is fixedly installed on one side of the interior of the movable palletizer frame 1, and the palletizer base 2 is placed inside the frame. One side of the base 2 contacts the stop block 6. Two positioning servo cylinders 8 are fixedly installed on both the left and right sides of the frame. Center positioning frames 7 are slidably installed on the front and rear sides of the frame. The two sides of the center positioning frames 7 are fixedly connected to the drive ends of the positioning servo cylinders 8. When palletizing mining coal gangue bricks, the... The movable palletizing frame 1 is moved to one side of the coal gangue brick conveying frame. The palletizing base frame 2 is placed inside the movable palletizing frame 1, so that one side of the palletizing base frame 2 contacts one side of the stop block 6. The positioning servo electric cylinders 8 on both sides of the movable palletizing frame 1 drive the front and rear center positioning frames 7 to clamp and position the palletizing base frame 2 inside the movable palletizing frame 1, ensuring that the palletizing base frame 2 is in the middle inside the movable palletizing frame 1, which facilitates the subsequent palletizing of coal gangue bricks.

[0034] Specifically, the movable palletizing frame 1 is equipped with drive components 3 on both the front and rear sides, and an adjustment unit 4 is provided above the two drive components 3. A palletizing unit 5 is also provided at the bottom of the adjustment unit 4. The drive components 3 on the front and rear sides of the movable palletizing frame 1 drive the adjustment unit 4 to move left and right above the movable palletizing frame 1. The adjustment unit 4 controls the forward and backward movement of the palletizing unit 5 inside the movable palletizing frame 1. The adjustment unit 4 can also control the angle rotation of the palletizing unit 5, which facilitates the angle adjustment when palletizing coal gangue bricks, thereby effectively improving the palletizing flexibility of coal gangue bricks.

[0035] As a further explanation of the solution in this embodiment, the drive assembly 3 includes a screw drive frame 9 and a fixed frame 12. The specific structure of the drive assembly 3 on the front of the movable palletizer frame 1 will be described below. The drive assembly 3 on the back of the movable palletizer frame 1 is symmetrically arranged. The screw drive frame 9 is fixedly arranged on the lower part of the front of the movable palletizer frame 1, and the drive screw 10 is driven by a motor inside the screw drive frame 9. An axial adjustment frame 11 is also slidably arranged on the front of the screw drive frame 9, and the lower part of the axial adjustment frame 11 is threadedly connected to the surface of the drive screw 10. The motor inside the screw drive frame 9 controls the drive screw 10 to rotate in both directions. With the threaded connection between the drive screw 10 and the axial adjustment frame 11, the axial adjustment frame 11 can slide left and right along the screw drive frame 9. A fixed frame 12 is also fixedly installed on the upper front of the movable palletizing rack 1, and the fixed frame 12 has a drive internal gear groove 13 inside. A drive motor 14 is fixedly installed on the front of the axial adjustment frame 11, and a drive gear 15 is fixedly installed at one end of the output shaft of the drive motor 14. One side of the drive gear 15 extends into the interior of the fixed frame 12, and the tooth surface of the drive gear 15 meshes with the tooth surface of the drive internal gear groove 13. Rubber sealing strips are provided inside both the screw drive frame 9 and the fixed frame 12, and the rubber sealing strips have an opening in the middle to protect the drive screw 10 and the drive internal gear groove 13 from dust.

[0036] It should be noted that when controlling the palletizing unit 5 to slide left and right, the rotation of the drive screw 10 drives the axial adjustment frame 11 to slide along the screw drive frame 9. The output shaft of the drive motor 14 controls the drive gear 15 to mesh with the drive internal gear groove 13 inside the fixed frame 12 to ensure the stability of the axial adjustment frame 11 during the left and right sliding process. Even if the motor inside the screw drive frame 9 fails, the left and right sliding control can still be achieved by the drive motor 14 in conjunction with the drive gear 15 and the drive internal gear groove 13. Conversely, when the drive motor 14 fails, the left and right sliding control is achieved by the motor inside the screw drive frame 9 controlling the drive screw 10.

[0037] As a further explanation of the scheme in this embodiment, the adjustment unit 4 includes a radial adjustment frame 17. A lifting servo cylinder 16 is fixedly installed inside both the front and rear axial adjustment frames 11. The radial adjustment frame 17 is fixedly installed at the top of the drive shaft of the two lifting servo cylinders 16. A radial adjustment screw 18 is installed inside the radial adjustment frame 17 via a motor rotation. A mating adjustment block 19 is slidably installed inside the radial adjustment frame 17. The interior of the mating adjustment block 19 is threadedly connected to the surface of the radial adjustment screw 18, and the bottom of the mating adjustment block 19 is fixedly installed... A fixed plate 20 is provided, and rotating support frames 22 are fixedly provided on both sides of the bottom of the fixed plate 20. A rotating frame 21 is rotatably provided at the bottom of the fixed plate 20, and the outer circumferential surface of the rotating frame 21 is located inside the two rotating support frames 22 for rotational setting. A rotating control motor 24 is fixedly provided at the top of the fixed plate 20, and a rotating control gear 25 is fixedly provided at the bottom end of the output shaft of the rotating control motor 24. A driven gear 26 is fixedly provided at the middle of the top of the rotating frame 21, and the tooth surface of the driven gear 26 meshes with the tooth surface of the rotating control gear 25 for transmission.

[0038] It should be noted that when the palletizing unit 5 slides back and forth inside the movable palletizing frame 1, the radial adjustment screw 18 inside the radial adjustment frame 17 rotates in both directions, thereby allowing the adjusting block 19 to slide back and forth inside the radial adjustment frame 17; when the palletizing unit 5 rotates at an angle, the output shaft of the rotary control motor 24 controls the rotary control gear 25 to rotate, and the meshing transmission between the rotary control gear 25 and the driven gear 26 allows the rotating frame 21 to rotate at an angle.

[0039] As a further explanation of the scheme in this embodiment, the stacking unit 5 includes two mounting frames 23 symmetrically arranged at the bottom of the rotating frame 21, and several stacking frames 28 are movably arranged on opposite sides of the two mounting frames 23. The two stacking frames 28 form a group, and the top of the two stacking frames 28 in a group is fixedly provided with telescopic control cylinders 31. Movable frames 29 are slidably arranged inside the several groups of stacking frames 28, and one end of the drive shaft of the two telescopic control cylinders 31 is fixedly connected to one side of the movable frame 29. The movable frame 29 is controlled to slide between the two stacking frames 28 by the drive end of the two telescopic control cylinders 31, so that several coal gangue bricks can be stacked and stacked by the several groups of stacking frames 28. Then, under the action of the axial adjustment frame 11, the radial adjustment frame 17 and the rotating frame 21, the coal gangue bricks stacked by the several groups of stacking frames 28 are sent to the top of the stacking base frame 2 for feeding and stacking.

[0040] Furthermore, a palletizing control gear 30 is installed inside the palletizing frame 28 via a motor, and one side of the palletizing control gear 30 extends to the outside of the palletizing frame 28. A palletizing adjustment groove 27 is provided on one side of the mounting frame 23, and the tooth surface of the palletizing adjustment groove 27 meshes with the tooth surface of the palletizing control gear 30 for transmission. The palletizing control gear 30 is controlled to rotate forward and backward by the motor inside the palletizing frame 28. According to the meshing transmission relationship between the palletizing control gear 30 and the palletizing adjustment groove 27, the palletizing frame 28 can move up and down along the palletizing adjustment groove 27.

[0041] Furthermore, a rubber gasket 36 is fixedly installed in the middle of the bottom of the movable frame 29, and an air blowing block 37 and several top adsorption blocks 38 are fixedly installed inside the rubber gasket 36; wherein, a micro air pump and a micro vacuum pump are installed on the top of the movable frame 29, and several top adsorption blocks 38 are connected to the micro vacuum pump through conduits. Several top adsorption blocks 38 are arranged in a ring at equal angles around the air blowing block 37, and the inside of the air blowing block 37 is connected to the air outlet of the micro air pump through a conduit.

[0042] Furthermore, limit servo cylinders 34 are fixedly installed on both the left and right sides of the bottom of the movable frame 29, and a central limit frame 33 is fixedly installed on the drive end of each of the left and right limit servo cylinders 34; adsorption control frames 35 are slidably installed on both the front and rear sides of the bottom of the movable frame 29, and a control block 32 is fixedly installed on the top of the movable frame 29. A lead screw is installed inside the control block 32 through a motor rotation, and the surface of the lead screw is connected to the internal threads of the two adsorption control frames 35; wherein, the two sides of the lead screw surface are respectively provided with external threads with opposite directions of rotation. By controlling the rotation of the lead screw, the two... The adsorption control frame 35 slides back and forth at the bottom of the movable frame 29. When adsorbing and feeding coal gangue bricks, the coal gangue bricks are first centered by the center limiting frame 33 set on the left and right sides. The adsorption control frame 35 set on the front and rear sides is used to correct the center position of the coal gangue bricks so that the coal gangue is in the exact center position at the bottom of the movable frame 29. Then, the air blowing block 37 is used to blow air onto the adsorption end face of the coal gangue bricks to blow away the dust on the adsorption end face of the coal gangue bricks. Finally, several top adsorption blocks 38 are used to adsorb and position the adsorption end face of the coal gangue bricks.

[0043] Furthermore, an adsorption regulating cylinder 39 is fixedly installed inside the adsorption regulating frame 35, and a connecting block 40 is fixedly installed at the bottom end of the drive shaft of the adsorption regulating cylinder 39. An adjusting block 41 is rotatably installed at the bottom of the connecting block 40, and a rotating shaft 42 is fixedly installed at the top inside the adjusting block 41. The two ends of the rotating shaft 42 are rotatably connected to the inner wall of the connecting block 40, and a built-in servo motor is installed inside the rotating shaft 42. The rotating shaft 42 is controlled to rotate inside the connecting block 40 by the output shaft of the built-in servo motor, thereby adjusting the side positioning angle of the coal gangue brick and enhancing the positioning flexibility of the side of the coal gangue brick.

[0044] Furthermore, a micro motor 43 is fixedly installed on one side of the adjusting block 41, and two adsorption extension frames 46 are rotatably installed on one side of the adjusting block 41. A control gear 44 and a transmission gear 45 are fixedly installed on one side of the two adsorption extension frames 46 respectively. One end of the output shaft of the micro motor 43 is fixedly connected to the inside of the control gear 44, and the tooth surface of the transmission gear 45 meshes with the tooth surface of the control gear 44 for transmission. Side adsorption blocks 47 are fixedly installed on the upper side of one side of the adjusting block 41 and on the lower side of one side of the two adsorption extension frames 46. A micro vacuum pump is installed inside the adjusting block 41 and the two adsorption extension frames 46 to control the side adsorption blocks 47 to adsorb and position the sides of the coal gangue bricks. The output shaft of the micro motor 43 controls the control gear 44 to rotate clockwise. Due to the external meshing of the teeth between the control gear 44 and the transmission gear 45, the transmission gear 45 rotates counterclockwise synchronously, causing the two adsorption extension frames 46 to rotate in two directions respectively. After the two driven gears 26 are unfolded, the side adsorption blocks 47 on one side of the two adsorption extension frames 46 are used to further expand the adsorption area on the side of the coal gangue brick, thereby ensuring the stability of the coal gangue brick during the adsorption and stacking process.

[0045] Furthermore, this embodiment also discloses a working method for a mining palletizer with an adsorption-type feeding mechanism, including the following steps:

[0046] Step 1: Using the casters on both sides of the bottom of the movable palletizing frame 1, move the movable palletizing frame 1 to the preset working position of the mining coal gangue brick conveyor frame, ensuring that the palletizing unit 5 can cover the coal gangue brick grabbing area on the conveyor frame and the palletizing area of ​​the palletizing base frame 2. Place the palletizing base frame 2 inside the movable palletizing frame 1, so that one side of the palletizing base frame 2 is in close contact with one side of the fixed stop block 6 inside the movable palletizing frame 1. The stop block 6 achieves the initial lateral limitation of the palletizing base frame 2, preventing the bottom... If a significant offset occurs during palletizing, the positioning servo cylinders 8 fixed on the left and right sides of the movable palletizing frame 1 are activated. The drive end of the positioning servo cylinder 8 pushes the central positioning frame 7, which is slidably set on the front and rear sides inside the movable palletizing frame 1, so that the two central positioning frames 7 clamp the palletizing base frame 2 from the front and rear directions. After the drive end of the positioning servo cylinder 8 reaches the preset stroke, the palletizing base frame 2 is stably fixed in the middle position inside the movable palletizing frame 1, completing the basic positioning of palletizing and preparing for subsequent precise palletizing.

[0047] Step 2: Start the motor inside the screw drive frame 9 in the drive assembly 3. The motor drives the drive screw 10 to rotate forward or in reverse. Since the lower part of the axial adjustment frame 11 is threadedly connected to the surface of the drive screw 10, the rotation of the drive screw 10 causes the axial adjustment frame 11 to slide left and right along the length of the screw drive frame 9. At the same time, the drive motor 14 fixed on the front of the axial adjustment frame 11 starts, and its output shaft drives the drive gear 15 to rotate. One side of the drive gear 15 extends into the interior of the fixed frame 12 and meshes with the drive internal gear groove 13 in the fixed frame 12. The gear meshing further ensures the stability of the left and right sliding of the axial adjustment frame 11. If the motor inside the screw drive frame 9 fails, the axial adjustment frame 11 can be slid left and right by the drive motor 14 in conjunction with the drive gear 15 and the drive internal gear groove 13. Conversely, if the drive motor 14 fails, it can also be driven by the motor inside the screw drive frame 9 to ensure that the adjustment process is not interrupted. The sliding of the axial adjustment frame 11 synchronously drives the adjustment unit 4 and the stacking unit 5 connected above it to move left and right until the stacking unit 5 moves to the top of the coal gangue brick conveying frame, ready to absorb the material.

[0048] Step 3: Start the lifting servo cylinders 16 fixed inside the two axial adjustment frames 11. The drive shaft of the lifting servo cylinders 16 extends or shortens, driving the radial adjustment frame 17 fixed at its top to rise or fall. The rising and falling of the radial adjustment frame 17 is synchronized with the lower adjusting block 19, fixing plate 20 and stacking unit 5 to rise or fall until the top adsorption block 38 and side adsorption block 47 of the adsorption structure of the stacking unit 5 reach the preset adsorption distance with the surface of the coal gangue bricks on the conveyor frame.

[0049] Step 4: Start the motor inside the radial control frame 17. The motor drives the radial control screw 18 to rotate forward or backward. Since the inner part of the adjusting block 19 is threadedly connected to the surface of the radial control screw 18, the rotation of the radial control screw 18 causes the adjusting block 19 to slide back and forth along the length of the radial control frame 17. The sliding of the adjusting block 19 synchronously drives the fixed plate 20, the rotating frame 21 and the stacking unit 5 at its bottom to move back and forth, so that the adsorption structure of the stacking unit 5 is accurately aligned with the coal gangue bricks to be adsorbed on the conveying frame.

[0050] Step 5: If there is an angle deviation in the placement of the coal gangue bricks on the conveyor frame, start the rotary control motor 24 fixed on the top of the fixed plate 20. The output shaft of the rotary control motor 24 drives the rotary control gear 25 to rotate. Since the rotary control gear 25 meshes with the driven gear 26 fixed in the middle of the top of the rotating frame 21, the rotation of the driven gear 26 drives the rotating frame 21 to rotate around the rotation connection point between it and the fixed plate 20. The rotation of the rotating frame 21 synchronously drives the bottom stacking unit 5 to rotate until the adsorption structure of the stacking unit 5 is completely in contact with the adsorption end face and side of the coal gangue brick, thus completing the angle calibration.

[0051] Step 6: Activate the limit servo cylinders 34 fixed on the left and right sides of the bottom of the movable frame 29. The drive end of the limit servo cylinder 34 pushes the central limit frame 33 to move towards the coal gangue brick, clamping and limiting the coal gangue brick from the left and right sides to achieve left and right positioning. Activate the motor inside the control block 32 fixed on the top of the fixed plate 20. The motor drives the lead screw inside the control block 32 to rotate. Since the lead screw has external threads with opposite directions on both sides of its surface, and the lead screw is connected to the internal threads of the two adsorption control frames 35, the rotation of the lead screw causes the two adsorption control frames 35 to slide in opposite directions at the bottom of the movable frame 29, clamping and limiting the coal gangue brick from the front and rear sides. Together with the central limit frame 33, the coal gangue brick is positioned at the exact center of the bottom of the movable frame 29, completing the positioning calibration.

[0052] Step 7: Activate the micro air pump at the top of the movable frame 29. The airflow generated by the micro air pump is delivered through a conduit to the air blowing block 37 inside the rubber gasket 36 at the bottom of the movable frame 29. The airflow is ejected from the air blowing block 37 to clean the top surface of the coal gangue brick's adsorption end face, removing the attached mineral dust and preventing dust from obstructing the subsequent adsorption effect. Activate the micro vacuum pump at the top of the movable frame 29. The micro vacuum pump creates negative pressure on the top adsorption block 38 through a conduit, causing the top adsorption block 38 to tightly adhere to the adsorption end face of the coal gangue brick, achieving... The top surface is fixed by adsorption; the adsorption regulating cylinder 39 fixed inside the adsorption regulating frame 35 is activated, the drive shaft of the adsorption regulating cylinder 39 extends or shortens, driving the connecting block 40 and the regulating block 41 to rise and fall, so that the side adsorption block 47 on one side of the regulating block 41 is in contact with the side of the coal gangue brick; if the side of the coal gangue brick is tilted, the built-in servo motor inside the rotating shaft 42 is activated, the motor drives the rotating shaft 42 to rotate on the inner wall of the connecting block 40, and then drives the regulating block 41 to rotate until the side adsorption block 47 is completely in contact with the side of the coal gangue brick.

[0053] Step 8: Start the micro motor 43 fixed on one side of the adjusting block 41. The output shaft of the micro motor 43 drives the control gear 44 to rotate clockwise. Since the control gear 44 meshes with the transmission gear 45, the transmission gear 45 rotates counterclockwise synchronously, driving the two adsorption extension frames 46 to unfold in opposite directions, so that the side adsorption blocks 47 on one side of the adsorption extension frame 46 fit against other areas on the side of the coal gangue brick. Start the micro vacuum pump inside the adjusting block 41 and the adsorption extension frame 46 to generate negative pressure on the side adsorption blocks 47, so as to achieve multi-area adsorption and fixation on the side of the coal gangue brick. Through the synergistic adsorption of the "top surface + multiple sides", it is ensured that the coal gangue brick does not fall off or tilt during transportation.

[0054] Step 9: Repeat steps 2-8. Drive the palletizing unit 5 left and right to be directly above the palletizing base 2 using the drive component 3. Lower the palletizing unit 5 to the preset palletizing height on the palletizing base 2 using the lifting servo cylinder 16. Move the palletizing unit 5 back and forth to the preset palletizing position on the palletizing base 2 using the radial adjustment screw 18. Turn off all micro vacuum pumps. The negative pressure on the top adsorption block 38 and side adsorption block 47 disappears, and the coal gangue bricks are stably placed on the palletizing base 2, completing a single palletizing operation. If multi-layer palletizing is required... The motor inside the palletizing frame 28 is started, and the motor drives the palletizing control gear 30 to rotate forward or reverse. Since the palletizing control gear 30 meshes with the palletizing adjustment groove 27 on one side of the mounting frame 23, the palletizing frame 28 rises and falls along the palletizing adjustment groove 27, which drives the movable frame 29 and the adsorption structure to rise and fall, adapting to the height requirements of the next layer of palletizing. At the same time, the telescopic control electric cylinder 31 can be started, and its drive end pushes the movable frame 29 to slide inside the palletizing frame 28, adjusting the extension length of the movable frame 29 to adapt to different palletizing spacing requirements.

[0055] Step 10: Repeat steps 6-9 until the coal gangue bricks on the palletizing base frame 2 reach the preset number of palletizing layers or quantities; then, turn off all drive motors and electric cylinders, release the clamping of the central positioning frame 7 on the palletizing base frame 2, and remove the palletizing base frame 2 from the inside of the movable palletizing machine frame 1 after palletizing; finally, move the equipment to the storage position using the moving wheels of the movable palletizing machine frame 1 to complete the entire palletizing operation process.
