Description

Technical Field

[0001] The utility model belongs to the technical field of metal smelting, and in particular relates to a covering agent flattening device. Background Art

[0002] In the process of gold ore smelting and enrichment, gold ore powder and corresponding additives are added to the crucible and mixed evenly, and then a covering agent needs to be poured on the upper layer to play a role of isolation and protection. The covering agent is directly poured into the crucible, and the surface is uneven and loose, resulting in poor coverage. The covering agent needs to be pressed flat before hot melting. Traditionally, most of the flattening is done manually with tools, which puts a heavy burden on the workers and has low efficiency. Currently, there are also some flattening devices that place the crucible in a fixed position under the flattening device to complete the flattening operation. Although this can replace the manual flattening of the covering agent, placing the crucibles one by one is inefficient. In addition, when the crucible is transported to the flattening device using an existing chain conveyor, the pressure head needs to be aligned with the center of the crucible. When the crucible travels on the chain conveyor, it may sometimes produce some deviations due to mechanical fatigue loosening of the chain plate and operating errors of the chain plate transmission, making it easy for the pressure head of the flattening device to collide with the wall of the crucible, causing damage to the flattening device and the crucible, or even if the deviation is large, the pressure head may collide with the upper edge of the crucible, making it difficult to complete the flattening operation. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a covering agent flattening device with a deviation correction function, so as to solve the problem in the prior art that the crucible is deviated during its movement and it is difficult to complete the flattening operation.

[0004] The utility model provides a covering agent flattening device, comprising:

[0005] A flattening mechanism, the flattening mechanism comprising a pressing head capable of reciprocating up and down; and

[0006] The positioning mechanism comprises a horizontal linear reciprocating mechanism, a slot-type positioning body driven and connected to the horizontal linear reciprocating mechanism, and positioning pieces arranged on a pair of sides of the slot-type positioning body, wherein the slot-type positioning body and the positioning piece are used to clamp the two sides of the crucible.

[0007] Optionally, the positioning member includes a fixed bracket and a blocking rod arranged on the bracket, and the length direction of the blocking rod is perpendicular to a driving direction of the horizontal linear reciprocating mechanism.

[0008] Optionally, the bracket includes a vertical pole, a clamping block clamped on the vertical pole and a cross bar arranged on the clamping block, the height of the cross bar relative to the vertical pole is adjusted by the clamping block, and one end of the cross bar is fixedly connected to the blocking rod.

[0009] Optionally, the clamp block is provided with two mutually perpendicular through holes, two mutually perpendicular through slots and two mounting holes, bolts are arranged in the mounting holes, the two through slots extend to the two through holes respectively, and the clamp block compresses the through slots to clamp the vertical pole and the horizontal pole by tightening the two bolts.

[0010] Optionally, the positioning member comprises a second horizontal linear reciprocating mechanism and a second slot-type positioning body driven by the second horizontal linear reciprocating mechanism, and the first slot-type positioning body and the second slot-type positioning body are used to clamp two sides of the crucible.

[0011] Optionally, a surface of the slot-type positioning body for contacting the crucible is a symmetrical arc surface or a symmetrical bent surface.

[0012] Optionally, the horizontal linear reciprocating mechanism is a pneumatic cylinder or an electric cylinder.

[0013] Optionally, the flattening mechanism further includes a gantry and a linear reciprocating drive disposed on the gantry, and an actuating end of the linear reciprocating drive is fixedly connected to the top of the pressing head.

[0014] Optionally, the covering agent flattening device also includes a chain conveyor, which is provided with a chain plate, the flattening mechanism and the positioning mechanism are fixedly connected to the chain conveyor, the pressure head is located directly above the chain plate, and the slot-type positioning body and the positioning member are located on both sides of the chain plate.

[0015] Optionally, a positioning hole for placing the crucible is provided on the chain plate, and a receiving plate is provided at the bottom of the chain plate.

[0016] The beneficial effect of the utility model is that when the crucible is conveyed to the bottom of the flattening mechanism, the horizontal linear reciprocating mechanism is used to drive the slot-type positioning body and cooperate with the positioning piece to clamp the crucible. Because the slot-type positioning body and the clamping center of the positioning piece are fixed at one point, the crucible is pushed to the specified position, thereby compensating for the mechanical fatigue loosening of the chain plate and the running error of the chain plate transmission, and correcting the crucible so that the crucible is just under the pressure head. At this time, the pressure head moves downward to flatten and tighten the covering agent, avoiding the pressure head from colliding with the wall and upper edge of the crucible, thereby successfully completing the flattening operation and not easily damaging the pressure head and the crucible.

DETAILED DESCRIPTION

[0024] like Figure 1-6 As shown, the utility model provides a covering agent flattening device, comprising: a flattening mechanism 10 and a positioning mechanism 20, wherein the flattening mechanism 10 includes a pressure head 11 that can reciprocate up and down; the positioning mechanism 20 includes a horizontal linear reciprocating mechanism 21, a slot-type positioning body 22 drivingly connected to the horizontal linear reciprocating mechanism 21, and a positioning member 23 arranged on the opposite side of the slot-type positioning body 22, and the slot-type positioning body 22 and the positioning member 23 are used to clamp the two sides of the crucible 40.

[0025] Compared with the prior art, the covering agent flattening device provided by the utility model, when the crucible 40 is transported to the bottom of the flattening mechanism 10, the horizontal linear reciprocating mechanism 121 is used to drive the slot-type positioning body 12, and cooperate with the positioning piece 23 to clamp the crucible 40. Because the clamping center of the slot-type positioning body 12 and the positioning piece 23 is fixed at one point, the crucible 40 is pushed to the specified position, thereby compensating for the mechanical fatigue loosening of the chain plate 31 and the operation error of the chain plate 31 transmission, and correcting the crucible 40 so that the crucible 40 is just under the pressure head 11. At this time, the pressure head 11 moves downward to flatten and tighten the covering agent, avoiding the pressure head 11 from colliding with the wall and upper edge of the crucible 40, thereby successfully completing the flattening operation and not easily damaging the pressure head 11 and the crucible 40.

[0026] In one embodiment, see Figure 3The positioning member 23 includes a fixed bracket and a blocking rod 234 arranged on the bracket, and the length direction of the blocking rod 234 is perpendicular to the driving direction of the horizontal linear reciprocating mechanism 21. Among them, if the crucible 40 deviates to the right, it will first contact the end of the baffle 234. Because the crucible 40 is an arc wall, it is guided to move to the right by the reaction force of the baffle 234 until it just breaks away. When the crucible 40 is located below the pressure head 11, the horizontal linear reciprocating mechanism 21 drives the slot-type positioning body 22. If the crucible 40 is offset front and back, the slot of the slot-type positioning body 22 will push the crucible 40. The slot-type positioning body 22 and the baffle 234 form a three-point centering structure, thereby positioning the crucible 40 directly below the pressure head 11. Subsequently, the pressure head 11 moves downward for a certain distance to flatten the covering agent. Then the pressure head 11 is reset, and the slot-type positioning body 22 is reset again. The crucible 40 moves forward, and the following crucible 40 arrives below the pressure head 11. Repeat the above operation to ensure that the pressure head 11 successfully flattens the covering agent in the crucible 40 each time.

[0027] For further information, see Figure 4 The bracket includes a vertical rod 231, a clamping block 232 clamped on the vertical rod 231, and a cross bar 233 arranged on the clamping block 232. The cross bar 233 is adjusted in height relative to the vertical rod 231 by the clamping block 232, and one end of the cross bar 233 is fixedly connected to the blocking rod 234. Specifically, the clamping block 232 is clamped on the vertical rod 231 by itself, and can be adjusted to a loose state, so that the clamping block 232 can adjust the height up and down along the vertical rod 231, and the height of the cross bar 233 is adjusted accordingly, so that the blocking rod 234 and the slot-type positioning body 22 are at the same level, avoiding the tendency of the blocking rod 234 and the slot-type positioning body 22 to deflect the crucible 40, which is conducive to improving the positioning accuracy. It should be noted that the number of brackets for fixing the blocking rod 234 is preferably 2, 3, or 4. In some cases, 1 or more brackets can be selected to fix the blocking rod 234.

[0028] For further information, see Figure 6The clamp block 232 is provided with two mutually perpendicular through holes 2321, two mutually perpendicular through slots 2322 and two mounting holes, bolts 2323 are arranged in the mounting holes, and the two through slots 2322 extend to the two through holes 2321 respectively. The clamp block 232 compresses the through slots 2322 by tightening the two bolts 2323 to clamp the vertical rod 231 and the horizontal rod 233. Specifically, the clamping block 232 is made of steel or aluminum alloy, and has an overall shape of a rectangular parallelepiped with mutually perpendicular rounded corners at both ends. The two through holes 2321 are respectively used to penetrate the vertical rod 231 and the horizontal rod 233, so that the two are distributed perpendicular to each other. By loosening the two bolts 2323, the two through grooves 2322 become wider under the elastic action, and the cross-sectional area of ​​the corresponding through hole 2321 becomes larger. The vertical rod 231 and the horizontal rod 233 can be moved relative to the clamping block 232, and the height and lateral position of the horizontal rod 233 can be adjusted respectively, and then the bolts 2323 are tightened and fixed, thereby, the height of the blocking rod 234 and the horizontal distance relative to the slot-type positioning body 22 can be adjusted, so that it can fit more closely to the surface of the crucible 40, and can be adapted to crucibles 40 of different specifications.

[0029] In another embodiment, see Figure 5 The positioning member 23 includes a horizontal linear reciprocating mechanism 235 and a horizontal linear reciprocating mechanism 236 driven by the horizontal linear reciprocating mechanism 235. The slot-type positioning body 1 22 and the horizontal linear reciprocating mechanism 236 are used to clamp the two sides of the crucible 40. In this way, when the positioning mechanism 20 positions the crucible 40, the horizontal linear reciprocating mechanism 1 21 and the horizontal linear reciprocating mechanism 235 respectively drive the slot-type positioning body 1 22 and the horizontal linear reciprocating mechanism 236 to clamp the crucible 40 together. Because the clamping center of the slot-type positioning body 22 and the horizontal linear reciprocating mechanism 236 is determined, the crucible 40 can be accurately positioned directly below the pressure head 11. The pressure head 11 then moves downward a certain distance to flatten the covering agent. The pressure head 11 is then reset, the slot-type positioning body 22 and the horizontal linear reciprocating mechanism 236 are reset, and the crucible 40 is then transferred forward. The following crucible 40 arrives below the pressure head 11, and the above operation is repeated to ensure that the pressure head 11 can successfully flatten the covering agent in the crucible 40 each time.

[0030] In one embodiment, the side of the slot-type positioning body 22 that contacts the crucible 40 is a symmetrical arc surface or a symmetrical bending surface to ensure accurate positioning of the crucible 40. The symmetrical arc surface or the symmetrical bending surface here is based on the middle interface of the slot-type positioning body 22 itself as the symmetrical surface, wherein the symmetrical arc surface is preferably a semicircular arc surface, and the cross-section of the symmetrical bending surface is V-shaped or an isosceles trapezoid.

[0031] In one embodiment, the horizontal linear reciprocating mechanism 21 is a pneumatic cylinder or an electric cylinder. In some embodiments, the horizontal linear reciprocating mechanism 21 is an oil cylinder.

[0032] In one embodiment, see Figure 3 The flattening mechanism 10 also includes a gantry 12 and a linear reciprocating driver 13 disposed on the gantry 12, and the execution end of the linear reciprocating driver 13 is fixedly connected to the top of the pressure head 11. Specifically, the crucible 40 passes through the gantry 12 to reach the bottom of the linear reciprocating driver 13 (or the pressure head 11), and after the positioning operation, the linear reciprocating driver 13 drives the pressure head 11 vertically downward to flatten the covering agent, and the linear reciprocating driver 13 drives the pressure head 11 upward in the reverse direction to reset, and the crucible 40 is transported forward, and then the covering agent in the subsequent crucible 40 is flattened, and the operation is repeated to continuously flatten the covering agent in each crucible 40.

[0033] In this embodiment, the linear reciprocating drive 13 is an electric cylinder or a pneumatic cylinder. In some embodiments, the linear reciprocating drive 13 is an oil cylinder.

[0034] In this embodiment, the shape of the pressing head 11 is a truncated cone structure, which is more suitable for the shape of the inner wall of the crucible 40 and ensures that the covering agent is pressed flat.

[0035] In one embodiment, the covering agent flattening device further comprises a chain conveyor 30, on which a chain plate 31 is arranged, the flattening mechanism 10 and the positioning mechanism 20 are fixedly connected to the chain conveyor 30, the pressure head 11 is located directly above the chain plate 31, and the slot-type positioning body 12 and the positioning member 23 are located on both sides of the chain plate 31. Specifically, the chain conveyor 30 is used to transport the crucible 40 from the previous process operation to the covering agent flattening operation position, and then to the subsequent process operation position, the door frame 12 spans the plate chain and is fixedly installed on the frame of the chain conveyor 30, the horizontal linear reciprocating mechanism 121 and the positioning member 23 are respectively fixedly installed at corresponding positions on both sides of the frame, and the plate chain is driven by a stepper motor, which can more accurately control the transmission distance and the start-stop cycle.

[0036] In one embodiment, see Figure 2A positioning hole 311 for placing the crucible 40 is opened on the chain plate 31 , and a receiving plate 312 is provided at the bottom of the chain plate 31 . Specifically, the outer wall contour of the crucible 40 is a conical cylinder, and the positioning hole 311 is a circular hole whose diameter is larger than the diameter of the crucible 40, so as to facilitate the rapid placement of the crucible 40 and confine the crucible 40 to a certain area so that the crucible 40 will not be excessively offset on the chain conveyor 30. The positioning mechanism 20 can quickly position the crucible 40 and move the crucible 40 to a determined position in the positioning hole 311 to solve the movement deviation of the chain conveyor 30 and the deviation of the manipulator in placing the crucible 40 to the positioning hole, so that the flattening mechanism 10 can press the covering agent to the lowest end of the crucible without causing the crucible 40 to be under pressure, thereby preventing damage to the crucible 40; and the positioning hole 311 can prevent the crucible 40 from tipping over; the receiving plate 312 is a part of the chain plate 31 and is located directly below the positioning hole 311. The bottom of the crucible 40 is in contact with the receiving plate 312, which supports the crucible 40 and keeps the crucible 40 in a stable state at all times. After the covering agent flattening device is used for a long time, there will be some deviation in transporting the crucible 40 to the designated position due to thermal expansion and contraction and mechanical fatigue. At this time, the positioning accuracy and reliability of the crucible 40 can be further guaranteed by cooperating with the positioning mechanism 20.
