Description

Technical Field

[0001] This invention relates to a material feeding and conveying device, specifically a mining chain welding automatic material feeding and conveying device, belonging to the field of conveying technology. Background Technology

[0002] With the increasing demand for coal energy, the rapid development of coal mining machinery has been promoted. As one of the main equipment for integrated mechanized coal mining in underground mines, the high-strength circular link chain for mining, a transmission component on scraper conveyors, has also developed rapidly. The high-strength circular link chain is a key component on scraper conveyors in coal mines, and its quality and performance will directly affect the working efficiency of the equipment and the output of the coal mine.

[0003] In the automated welding and forming process of mining circular link chains, the mining chain bars need to be fed into a heating device for heating, and then bent and welded into circular link chains. However, the mining chain bars are usually cut into materials of equal length. During the cutting process, certain deformation occurs at the cutting position, resulting in burrs on the outer side of the welded circular link chains. The circular or elliptical circular link chains need to be deburred in the subsequent process. However, deburring circular link chains with curved surfaces and small central spaces is troublesome, resulting in a long processing cycle and high cost for the welding and forming process of mining circular link chains.

[0016] This invention provides an automatic feeding and conveying equipment for chain welding in mining, which has the following beneficial effects:

[0017] This mining chain welding automatic feeding and conveying equipment uses a rotating grinding component one to drive a fixedly connected grinding component two to rotate. The moving mining chain bar continues to pass through the space between the two grinding components two and between the two grinding components one at one end. The two rotating grinding components two remove the deformation and burrs caused by the cutting process of the mining chain bar. The two rotating grinding components one polish the outer side of the mining chain bar to reduce impurities on the outer side of the mining chain bar, ensure the quality of the mining chain bar processed into a mining chain, and reduce the cost of removing burrs and protrusions from round or elliptical mining chains in the future.

[0018] This automatic feeding and conveying equipment for mining chain welding uses a human-machine interface to control two pneumatic cylinders (cylinder 1 and cylinder 2) whose extension lengths are recalculated based on distance data. The extension lengths of these cylinders are calculated using pads of varying thicknesses to accommodate mining chain bars of different diameters transported within the conveying track. Therefore, the extension lengths of the two pneumatic cylinders automatically adapt to the different diameters of the mining chain bars. After the pads are replaced, the two pneumatic cylinders automatically adapt to the new diameter mining chain bars in the feeding and conveying equipment. This causes the clamping component 2, pushed by the two pneumatic cylinders, to move to the outside of the mining chain bar to support it, ensuring the stability of the mining chain bar during grinding and polishing by grinding components 1 and 2. The two pneumatic cylinders push the two grinding components 2 to form a grinding structure adapted to the mining chain bar, meeting the needs of transporting and welding different mining chain bars.

[0019] This automatic feeding and conveying equipment for mining chain welding features a pad installed inside the conveying track. Cut mining chain bars are placed at the higher end of the conveying track. Because both the conveying track and the pad are inclined, the mining chain bars roll towards the lower end of the conveying track under gravity. The length and inclination angle of the conveying track can be set as needed to transport the mining chain bars at different distances and speeds. The mining chain bars roll under the support of the inclined pads. The cut ends of the mining chain bars are suspended to avoid deformation during the cutting process affecting the conveying of the mining chain bars, and to reduce the possibility of tilting, displacement, or blockage of the conveying channel during the conveying process.

[0031] This invention provides an automatic feeding and conveying equipment for chain welding in mining.

[0032] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 It includes a feeding structure 2 and a feeding pipe 3. A conveying structure 1 is installed on one side of the feeding structure 2, and a feeding structure 4 is installed at the bottom of the conveying structure 1.

[0033] The conveying structure 1 includes a conveying track 11, a first fixed plate 15, a third fixed plate 19, a position sensor 112, a fourth fixed plate 118, a second gear 132, and multiple clamping components 121. A pad 12 is provided inside the conveying track 11. Each of the multiple clamping components 121 is fixedly connected to the fourth fixed plate 118 with two transmission rods 120. The transmission rods 120 pass through the first fixed plate 15. A transmission assembly is connected between the fourth fixed plate 118 and the third fixed plate 19. A positioning plate 111 is installed on the transmission assembly.

[0034] The top of the fixed plate 19 is rotatably mounted with an operating external threaded part 18. The position sensor 112 is electrically connected to two pneumatic cylinders 124 and two pneumatic cylinders 136. The piston ends of the two pneumatic cylinders 124 are fixedly connected to clamping parts 125. The piston ends of the two pneumatic cylinders 136 are fixedly connected to grinding parts 135. Grinding parts 142 are fixedly connected to the side of grinding parts 135 near clamping parts 125. Two guide rods 133 are arranged between the two grinding parts 135. The two guide rods 133 are fixedly connected to the inside of gear 132. Multiple support components are arranged between gear 132 and the conveying track 11. Gear 3 140 is meshed on one side of gear 132.

[0035] Specifically, the staff pre-programs the human-machine interface with a CNC program to control the operation of the feeding and conveying equipment, which consists of conveying structure 1, unloading structure 2, and feeding structure 4. When the feeding and conveying equipment is used to transport and collect mining chain bars, the human-machine interface controls the operation of two electrically connected pneumatic cylinders 136. The two pneumatic cylinders 136 are symmetrically arranged, such as... Figure 8 As shown, two pneumatic cylinders 136 simultaneously push the grinding component 135 fixedly connected to the piston end, causing the two grinding components 135 and the grinding component 142 fixedly connected to the grinding component 135 to move towards each other a distance. In the conveying structure 1, a pad 12 is installed inside the conveying track 11. Cut and shaped mining chain bars are placed at the higher end of the conveying track 11. Since the conveying track 11 and the pad 12 are both inclined, the mining chain bars roll towards the lower end of the conveying track 11 under the action of gravity. The length and inclination angle of the conveying track 11 can be set as needed to transport the mining chain bars at different distances and speeds.

[0036] Furthermore, there is a certain distance between the two sides of the pad 12 and the inner wall of the conveying track 11. The intact and smooth middle part of the mining chain bar is supported by the pad 12. The mining chain bar rolls under the support of the inclined pad 12. The cut ends of the mining chain bar are suspended to avoid the deformation of the mining chain bar during the cutting process from affecting the conveying of the mining chain bar. This reduces the possibility of the mining chain bar tilting or deviating and blocking the transport channel during the conveying process. Multiple clamping parts 121 are set at the lower end of the conveying track 11. The mining chain bar is supported by multiple arc-shaped clamping parts 121. The mining chain bar is conveyed to the processing area and the work is completed.

[0037] Subsequently, the human-machine interface device controls the electrically connected feeding structure 4 to operate. The telescopic pneumatic cylinder 41, fixedly installed at the bottom of the conveying track 11 within the feeding structure 4, operates. The fixed plate 9 42, fixedly connected to the piston end of the telescopic pneumatic cylinder 41, is driven by the telescopic pneumatic cylinder 41, causing the push rod 43, fixedly connected to one end of the fixed plate 9 42, to move. Since both sides of the conveying track 11 are provided with reserved slots 2 14, such as... Figure 3As shown, multiple clamping components 121 are positioned between two pre-reserved slots 14, and the center lines of the arc-shaped surfaces of clamping components 121, the pre-reserved slots 14, and the push rod 43 are on the same horizontal line. The mining chain bar is supported by the arc-shaped surfaces of the clamping components 121, so the center line of the mining chain bar is aligned with the center line of the fixing plate 42. When the fixing plate 42 passes through one pre-reserved slot 14, it pushes the mining chain bar towards the pre-reserved slot 14 near the unloading pipe 3, causing one end of the mining chain bar to be fixedly connected to the two clamping components 121 at the piston ends of the two pneumatic cylinders 124. The cylinder passes between 5; at this time, the human-machine interaction device controls the pneumatic cylinder 124 to extend to a certain length. The pneumatic cylinder 124, which is fixedly installed with the conveyor rail 11 through the fixed plate 5 123, pushes the clamping part 2 125 to move. Since the two pneumatic cylinders 124 are symmetrically arranged, the two clamping parts 2 125 move towards the mining chain bar at the same time. Finally, the two clamping parts 2 125 move to the outside of the mining chain bar to support the mining chain bar and prevent the mining chain bar from tilting and shaking later. At this time, the cutting and processing position of the mining chain bar in the direction of movement passes the two clamping parts 2 125.

[0038] The telescopic pneumatic cylinder 41, through the push rod 43, pushes the mining chain bar to continue moving, causing it to move between the two grinding parts 142. Simultaneously, while the human-machine interface controls the operation of the pneumatic cylinder 124, it also controls the electrically connected forward and reverse motor 141. The forward and reverse motor 141, fixedly connected to one side of the conveyor track 11, drives the gear 140, fixedly connected to its output end, to rotate. The rotating gear 140 applies rotational force to the meshing gear 132. Meanwhile, the fixed circular plate 131 in the support assembly is fixedly connected to... On the side of gear 2 132 away from the conveying track 11, the outer ring of the mounting bearing 130, which is fixedly sleeved on the outer side of the fixed circular plate 131, is fixedly connected to multiple fixing plates 7 129. The inner and outer rings of the mounting bearing 130 can rotate relative to each other, so the multiple fixing plates 7 129 do not affect the rotation of gear 2 132. Furthermore, one end of each fixing rod 2 128 fixedly connected inside the multiple fixing plates 7 129 is fixedly connected to a fixing plate 6 127. The fixing rods 1 126 fixedly connected to the multiple fixing plates 6 127 are all fixedly installed together with the conveying track 11. Figure 8 As shown, with the support of multiple fixed rods 126, multiple fixed plates 127, multiple fixed rods 128, multiple fixed plates 129, and mounting bearings 130, the relative position between gear 132 and the conveying track 11 remains unchanged, and gear 132 can rotate.

[0039] The rotating gear 3 140 drives gear 2 132 to rotate. Two pneumatic cylinders 2 136, fixedly connected inside gear 2 132, rotate. A grinding component 1 135, fixedly connected to the piston end of pneumatic cylinder 2 136, rotates. The rotating grinding component 1 135 drives a grinding component 2 142, fixedly connected to one side, to rotate. The moving mining chain bar continues to pass between the two grinding components 2 142 and between grinding components 1 135. The deformation and burrs of the mining chain bar, constantly propelled forward by thrust, come into contact with grinding component 2 142, becoming... The mining chain bar passes through the obstruction between two grinding components 142. Therefore, the two rotating grinding components 142 remove the deformation and burrs caused by the cutting process of the mining chain bar. Similarly, the impurities on the outside of the mining chain bar are removed by the rotating grinding components 135 as the moving mining chain bar passes through the obstruction between two grinding components 135. This reduces the impurities on the outside of the mining chain bar, ensures the quality of the mining chain bar processed into a mining chain, and reduces the cost of removing burrs and protrusions from round or elliptical mining chains.

[0040] After one end of the mining chain bar passes through two grinding parts 142 and 135, the other end enters the sealing part 21 through a round hole on one side of the sealing part 21 in the feeding structure 2. A transmission rod 22 is rotatably connected inside the sealing part 21. Multiple grooves for transporting the mining chain bar are opened on the outside of the bearing part 23, which is fixedly connected to the outside of the transmission rod 22. At this time, one groove aligns with the round hole. Finally, after the mining chain bar is polished, it completely enters the groove. Subsequently, the telescopic pneumatic cylinder 41 drives the push rod 43 to reset. One end of the transmission rod 22 extends to the outside of the sealing part 21 and is fixedly connected to a connector 24. A connector box 25 sleeved on the outside of the connector 24 is fixedly connected to the output end of the drive motor 26. Figure 2 As shown, the drive motor 26 drives the carrier 23 to rotate a certain angle through the plug box 25, the plug part 24 and the transmission rod 22. Then the drive motor 26 stops working, and at this time the empty groove is aligned with the round hole. The conveying structure 1 and the feeding structure 4 cooperate to continue the above work to convey and process the next mining chain bar.

[0041] Furthermore, the outer notch of the seal 21 is located at the top of the feeding pipe 3. When the mining chain bar inside a certain groove on the outside of the bearing 23 aligns with the outer notch of the seal 21, the mining chain bar falls into the feeding pipe 3 through the notch, allowing the mining chain bar to enter the heating equipment connected to the feeding pipe 3 for subsequent bending and welding processes.

[0042] Furthermore, in the transmission assembly, the fixing plate 19 presses against the top of the pad 12, and the fixing plate 15 fixedly installed on the conveyor track 11 is fixedly connected to three fixing plates 16, such as... Figure 3As shown, the two limiting members 17 and the operating external thread member 18, which are fixedly connected to the top two sides of the fixed plate 19, respectively pass through the three fixed plates 16. Under the limitation of the two limiting members 17, the fixed plate 19 can only move in the direction guided by the limiting members 17 and the fixed plate 16. The operating external thread member 18 is threadedly connected to the fixed plate 16. By rotating the operating external thread member 18, the fixed plate 19 connected to the bottom end of the operating external thread member 18 can be moved upward, so that the pad 12 is no longer fixed and the pad 12 can be disassembled. According to the diameter of the new specification mining chain bar, the pad 12 of the corresponding new thickness is installed inside the conveying track 11. Then, the operating external thread member 18 is rotated to push the fixed plate 19 to press onto the new pad 12, and the position of the pad 12 is fixed.

[0043] During the movement of the fixed plate 319, since the rack 110 in the transmission assembly is fixedly connected to the top of the fixed plate 319, as Figure 4 As shown, the rack 110 moves synchronously with the fixed plate 19. A transmission rod 114 is fixedly connected inside the gear 113 meshing on one side of the rack 110. Therefore, the moving rack 110 drives the gear 113 to rotate. One end of the transmission rod 114, fixedly connected inside the gear 113, passes through the fixed plate 15 and is rotatably connected to it. Thus, the gear 113 drives the transmission rod 114 to rotate. The winding frame 115, fixedly sleeved on the outer side of one end of the transmission rod 114, rotates, and a pull wire 116 is fixedly connected to the winding frame 115. Figure 7 As shown, the rotating take-up frame 115 takes up or unwinds the pull cable 116. Because the roller 117 on the outer side of the pull cable 116 is fixedly connected to the fixed plate 15, the roller 117 changes the direction of the pull cable 116, making the portion of the pull cable 116 facing the fixed plate 118 perpendicular to the fixed plate 118. Since the pull cable 116 is fixedly connected to the fixed plate 118, the pull cable 116 drives the fixed plate 118 to move horizontally. Furthermore, multiple spring-loaded telescopic rods 11 are fixedly connected between the fixed plate 118 and the fixed plate 15. 9. Multiple spring-loaded telescopic rods 119 apply a force away from the conveying track 11 to the fixed plate 4 118 in real time. As the pull wire 116 is unwound or wound, the distance between the fixed plate 4 118 and the conveying track 11 changes synchronously. The distance between the fixed plate 4 118 and the conveying track 11 changes under the influence of the thickness of the pad 12. Two transmission rods 2 120 are fixedly connected between the clamping member 121 and the fixed plate 4 118. Therefore, the clamping member 121 moves synchronously with the fixed plate 4 118 under the action of the transmission rods 2 120.

[0044] When the new thickness of the pad 12 is thinner than the previous pad 12, the fixing plate 3 19 that installs the limiting pad 12 finally moves downward, the winding frame 115 rotates to unwind the pull wire 116, the fixing plate 4 118 moves away from the fixing plate 15, and the clamping member 121 moves closer to the fixing plate 15. At this time, the distance between the clamping member 121 and the center line of the reserved groove 2 14 increases, allowing the clamping member 121 to support a mining chain bar with a larger diameter. When the new thickness of the pad 12 is thicker than the previous pad 12, the fixing plate 3 19 that installs the pad 12 finally moves upward, the winding frame 115 rotates to wind the pull wire 116, the pull wire 116 pulls the fixing plate 4 118 closer to the fixing plate 15, and the clamping member 121 moves away from the fixing plate 15. At this time, the distance between the clamping member 121 and the center line of the reserved groove 2 14 increases, allowing the clamping member 121 to support a mining chain bar with a larger diameter. 4. The distance between the center lines is shortened, so that the clamping part 121 supports the mining chain bar with a smaller diameter; the pad 12 can be replaced according to the thickness of the mining chain bar to be processed, and the positions of multiple clamping parts 121 are automatically adjusted according to the thickness of the mining chain bar to ensure that the arc-shaped clamping part 121 stably supports the mining chain bar, so that the center line of the mining chain bar is on the same horizontal line as the center line of the two reserved grooves 14, and the center line of the circular structure formed by the two clamping parts 125 and the center line of the circular structure formed by the two grinding parts 135 are on the same straight line as the center line of the reserved groove 14. This ensures that the mining chain bar can be clamped and supported by the two clamping parts 125 and can be ground and polished by the two grinding parts 135 and the two grinding parts 142 during the process of being pushed by the feeding structure 4.

[0045] Furthermore, the position sensor 112, which is fixedly connected to the fixed plate 15, is located on the top of the positioning plate 111, which is fixedly connected to the rack 110, such as... Figure 3As shown, after the positions of the fixed plate 19 and rack 110 change under the influence of the new thickness pad 12, the position of the positioning plate 111 changes synchronously. After the new pad 12 is installed, the operator starts the human-machine interface to control the material conveying equipment. The position sensor 112 detects the distance data between itself and the positioning plate 111. The distance data detected by gear 113 is fed back to the electrically connected human-machine interface. At this time, the human-machine interface controls the extension length of the two electrically connected pneumatic cylinders 124 and 136 to be recalculated according to the distance data. The extension length of the two pneumatic cylinders 124 and 136 controlled by the human-machine interface is calculated based on the pad 12 of different thicknesses. The pad 12 is designed to accommodate mining chain bars of different diameters transported within the conveying track 11. Therefore, the extension lengths of the two pneumatic cylinders 124 and 136 automatically adapt to the different diameters of the mining chain bars. After the pad 12 is replaced, the two pneumatic cylinders 124 and 136 automatically adapt to the new diameter of the mining chain bars in the feeding conveyor. This causes the clamping component 125, pushed by the two pneumatic cylinders 124, to move to the outside of the mining chain bar to support it, ensuring the stability of the mining chain bar during the grinding and polishing process by the grinding component 135 and the grinding component 142. The two pneumatic cylinders 136 push the two grinding components 142 to form a grinding structure adapted to the mining chain bar, meeting the needs of transporting and welding different mining chain bars.

[0046] Other, such as Figure 3 As shown, a reserved groove 13 is provided on the side of the pad 12 away from the grinding part 135. The reserved groove 13 provides space for the initial movement of the mining chain bar, and avoids the mining chain bar from contacting the cutting deformation part with the pad 12 before it is clamped and limited by the two clamping parts 125, which would cause the mining chain bar to tilt and shift, thus ensuring the smooth conveying of the pad 12.

[0047] Other, such as Figure 8 As shown, both grinding parts 135 are fixedly connected to the top and bottom of the fixing plate 134. Multiple fixing plates 134 are sleeved on the outside of the adjacent guide rod 133. Under the limiting guidance of the guide rod 133, the force on the pneumatic cylinder 136 is reduced during the process of the grinding part 135 moving and the grinding part 135 rotating to grind the mining chain bar.

[0048] Other, such as Figure 9As shown, a fixing plate 137 is fixedly connected to one end of a fixing rod 126. A limiting bearing 139 is sleeved on the outer side of a fixing rod 138 fixedly connected to the fixing plate 137.

A fixing circular plate 131 is located on the side of the gear 132 away from the conveying track 11. Therefore, the limiting bearing 139 and the fixing circular plate 131 cooperate to support and limit the gear 132, ensuring the stable operation of the gear 132.

[0049] Other, such as Figure 1 and Figure 2 As shown, the drive motor 26 is fixedly connected to the bottom of the conveying track 11. One end of the seal 21 is fixedly connected to an internally threaded tube 27. One end of each of the two internally threaded tubes 27 passes through the support frame 28. Bolts are installed inside the internally threaded tubes 27. Under the action of the bolts, the internally threaded tubes 27 cannot leave the support frame 28. Moreover, the plug-in 24 and the plug-in box 25 are also connected by screws. Therefore, the bolts and screws can be rotated and disassembled to remove the plug-in 24 and the seal 21. The seal 21 and the carrier 23 can be replaced so that the carrier 23 can adapt to the transportation of mining chain bars of different diameters.
