Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and particularly to an automatic plate stacking and packaging machine for rock wool board production and its operation method. Background Art

[0002] Rock wool board is an inorganic fiber board mainly made of basalt and processed by high-temperature melting. Strict packaging is required during production. The existing rock wool board packaging machines have single functions. The rock wool boards are not neatly stacked before packaging, which will affect the subsequent film covering packaging, reduce the packaging efficiency, and the non-neat packaging of rock wool boards occupies more space and also hinders the subsequent stacking and transportation of rock wool boards.

[0003] For example, an automatic plate stacking and packaging machine for rock wool board production with the publication number of CN212951259U includes a sorting box, a controller, a main box and a packaging oven. An inlet plate is arranged at the upper left of the main box, an outlet plate is arranged at the lower right of the main box, an air pump is arranged at the upper end of the main box, the upper left part of the upper end of the main box is fixedly connected with a vertical plate, a spray pipe is arranged at the upper end of the vertical plate, the lower end of the spray pipe is rotationally connected with the vertical plate through a shaft, the right end of the spray pipe is hermetically connected with the air pump through a hose, the middle part of the lower end of the spray pipe is rotationally connected with an electric telescopic rod through a hinge seat, and the right end of the electric telescopic rod is fixedly connected with the left end of the air pump. A slot hole is arranged on the inner wall of the lower end of the main box. The rock wool boards can be sorted by the movable clamping plates to ensure neat and beautiful packaging. At the same time, the rotatable spray pipe can effectively cool down the high-temperature rock wool boards. However, during the conveying process of the rock wool boards by the device, when sorting the rock wool boards by the clamping plates, when the clamping plates on both sides push the protruding rock wool boards on both sides, the bottom rock wool boards are still conveyed and driven, so that the bottom rock wool boards may deviate from the upper rock wool boards along the conveyor belt direction, and the clamping plates cannot correct the deviation in the conveyor belt direction. Therefore, after being sorted by the clamping plates, the rock wool boards may still be uneven, reducing the effects of subsequent film covering packaging and transportation.

[0004] Therefore, an automatic plate stacking and packaging machine for rock wool board production and its operation method are proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic plate stacking and packaging machine for rock wool board production and its operation method to solve the problem that the bottom rock wool boards may deviate from the upper rock wool boards along the conveyor belt direction, resulting in uneven rock wool boards after sorting, and reducing the effects of subsequent film covering packaging and transportation.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An automatic plate stacking and packaging machine for rock wool board production includes an outer box body, a rock wool board main body and supporting feet symmetrically and fixedly installed at the bottom of the outer box body. A conveyor belt is installed below the inner part of the outer box body; Further included are: Flattening components are evenly arranged on the top of the conveyor belt, and an auxiliary component is arranged on one side of the inner top surface of the outer box body; The flattening component includes a moving unit, a buffering unit, and an extrusion unit. The cooperation of the moving unit and the extrusion unit facilitates maintaining a stationary state when extruding and flattening the main body of the rock wool board, thereby reducing the situation of the upper and lower layers of the main body of the rock wool board shifting due to the conveying of the conveyor belt, and facilitating subsequent film covering and packaging processing of the main body of the rock wool board; The moving unit includes a fixed box fixedly installed on the surface of the conveyor belt. A top plate is slidably installed on the top of the fixed box. Contact plates are symmetrically and fixedly connected to the front and rear sides of the top plate. L-shaped plates are symmetrically installed on the top of the top plate, and the distance between the two L-shaped plates is adjustable. Two fixed rods are symmetrically and fixedly connected to the inner side of the fixed box. A moving block is slidably connected to the outer side of the fixed rod. The tops of the two moving blocks are fixedly connected to the top plate. A first spring is sleeved on the outer side of the fixed rod; The extrusion unit includes two mounting plates symmetrically arranged. The two mounting plates are respectively fixedly connected to the front and rear inner walls of the outer box body. Electric push rods are symmetrically and fixedly installed on the outer sides of the mounting plates. The telescopic ends of the electric push rods are fixedly connected to a partition plate. An extrusion plate is installed on one side of the partition plate. A sliding sleeve is fixedly connected to the lower part of the outer side of the mounting plate. A second spring is fixedly connected to the inside of the sliding sleeve. An arc-shaped block is fixedly connected to one side of the second spring.

[0007] Preferably, the buffering unit includes a temporary storage box symmetrically and fixedly installed inside the fixed box. A sliding rod is slidably connected to one side of the temporary storage box. One end of the sliding rod is fixedly connected to a piston plate. The piston plate fits against the inner wall of the temporary storage box and is slidably connected to the temporary storage box. A connecting strip is fixedly connected to one side of the moving block. The other end of the sliding rod passes through the temporary storage box and is fixedly connected to the connecting strip. The elastic coefficient of the two second springs is greater than that of the two first springs.

[0008] By adopting the above technical solution, within the time from the start of compression of the first spring to the compression limit, the positions of the top plate and the main body of the rock wool board remain unchanged. During this period, the electric push rod drives the partition plate and the extrusion plate to extrude and flatten the front and rear sides of the main body of the rock wool board, reducing the situation of the main body of the rock wool board being stacked and protruding unevenly.

[0009] Preferably, an air inlet pipe is installed on the outer side of one side of the temporary storage box, and an air outlet pipe is installed on the outer side of the other side of the temporary storage box. The air inlet pipe and the air outlet pipe are located on the side of the temporary storage box away from the connecting strip. Both the air inlet pipe and the air outlet pipe are communicated with the inside of the temporary storage box. Check valves are installed on the outer sides of both the air inlet pipe and the air outlet pipe. One end of the air outlet pipe away from the temporary storage box is connected to a spray head. The spray head is fixedly installed on one side of the moving block.

[0010] By adopting the above technical solution, when the moving block drives the connecting bar and the sliding rod to reset, the sliding rod drives the piston plate to extrude the air inside the temporary storage box, so that the gas is discharged through the air outlet pipe and the nozzle, thereby slowing down the reset speed of the connecting bar and the moving block.

[0011] Preferably, there are no less than two electric push rods. The bottom height of the partition board is lower than the top height of the L-shaped plate. An inner rod is slidably connected inside the partition board. The inner rod is fixedly connected with the extrusion plate. The horizontal height of the arc-shaped block is the same as that of the contact plate. A third spring is sleeved outside the inner rod. The third spring is fixedly installed between the partition board and the extrusion plate. An inclined rod is rotatably connected to one side of the partition board close to the extrusion plate. A fourth spring is fixedly connected between the outer side of the inclined rod and the extrusion plate. There are no less than two inclined rods.

[0012] By adopting the above technical solution, when the partition board drives the extrusion plate to extrude the main body of the rock wool board, the extrusion plate first contacts the main body of the rock wool board, and then the partition board continues to compress the third spring and drives the inclined rod to unfold. The inclined rod stretches the fourth spring, and the unfolding of the inclined rod plays a role in spreading the extrusion force.

[0013] Preferably, a double-headed lead screw is rotatably installed on the top of the top plate. The two L-shaped plates are respectively located on the outer sides of the double-headed lead screw. The L-shaped plates are threadedly connected with the double-headed lead screw. The first spring is located on the side of the moving block close to the double-headed lead screw. The two ends of the first spring are respectively fixedly connected with the moving block and the inner side wall of the fixed box.

[0014] By adopting the above technical solution, when the double-headed lead screw is rotated, the double-headed lead screw drives the two L-shaped plates to approach, so that the L-shaped plates on both sides are close to the front and back sides of the main body of the rock wool board.

[0015] Preferably, the auxiliary component includes symmetrically arranged connecting plates and mounting pieces. The connecting plates and the mounting pieces are both fixedly connected to one side of the inner top surface of the outer box body. A vertical plate is rotatably connected between the two connecting plates. The vertical plate is vertically arranged. An auxiliary roller is rotatably installed in a groove on one side of the vertical plate.

[0016] By adopting the above technical solution, when the conveyor belt drives the main body of the rock wool board to move, the right side of the main body of the rock wool board will contact the auxiliary roller.

[0017] Preferably, the auxiliary rollers are evenly arranged from top to bottom. There are no less than four auxiliary rollers. Fixing frames are symmetrically and fixedly connected to one side of the vertical plate close to the mounting piece.

[0018] By adopting the above technical solution, the auxiliary rollers cooperate with the baffle plates to squeeze and flatten the left and right sides of the main body of the rock wool board.

[0019] Preferably, a lower plate is rotatably connected between the two mounting plates. A cross bar is fixedly connected to the side of the lower plate away from the mounting plate. The cross bar is slidably connected to the two fixed frames, and stoppers are fixedly connected to both ends of the cross bar.

[0020] By adopting the above technical solution, the vertical plate drives the fixed frame to rotate, the cross bar slides inside the fixed frame, and the cross bar drives the lower plate to rotate around the mounting plate, assisting in squeezing and flattening the main body of the rock wool board.

[0021] An operation method of an automatic plate stacking and packaging machine for producing rock wool boards is as follows: Step 1: The operator places the stacked main body of the rock wool board on the top of the top plate, rotates the double-headed lead screw, the double-headed lead screw drives the two L-shaped plates to approach, so that the L-shaped plates on both sides are tightly attached to the front and back sides of the main body of the rock wool board. Then, the conveyor belt is started to convey, and the conveyor belt drives the fixed box and the top plate to move, thereby driving the stacked main body of the rock wool board to move. Step 2: When the conveyor belt drives the main body of the rock wool board to move, the right side of the main body of the rock wool board will contact the auxiliary roller. The main body of the rock wool board drives the auxiliary roller and the vertical plate to rotate and unfold around the connecting plate. The vertical plate drives the fixed frame to rotate, the cross bar slides inside the fixed frame, and the cross bar drives the lower plate to rotate around the mounting plate, so that the auxiliary roller cooperates with the baffle to squeeze and flatten the left and right sides of the main body of the rock wool board. Step 3: When the contact plate moves to the position of the arc-shaped block, the operator starts the electric push rod to work. Since the elastic coefficient of the second spring is greater than that of the first spring, the arc-shaped block blocks the contact plate and the top plate. The conveyor belt continues to drive the fixed box to move, and the top plate drives the moving block to move on the fixed rod and compress the first spring. The moving block simultaneously drives the sliding rod and the piston plate to move through the connecting bar. One-way valves are installed on the outer sides of the air inlet pipe and the air outlet pipe to achieve one-way conduction. The piston plate sucks air through the air inlet pipe. When the first spring is compressed to the limit, the contact plate will squeeze the arc-shaped block, and the arc-shaped block compresses the second spring and slides into the sliding sleeve. At this time, the elastic force of the first spring drives the moving block and the top plate to reset, and the moving block drives the connecting bar and the sliding rod to reset. The sliding rod drives the piston plate to squeeze the air inside the temporary storage box, so that the gas is discharged through the air outlet pipe and the nozzle, thereby slowing down the reset speed of the connecting bar and the moving block and preventing the instantaneous reset from causing the main body of the rock wool board to be stacked unevenly. Step 4: During the time when the first spring starts to be compressed to the compression limit, the electric push rod drives the partition plate and the extrusion plate to squeeze and flatten the front and back sides of the main body of the rock wool board, reducing the situation of the main body of the rock wool board being stacked convex and uneven, facilitating the subsequent packaging operation of the main body of the rock wool board. The L-shaped plate will block the partition plate to avoid excessive extrusion by the extrusion plate. The flattened main body of the rock wool board is conveyed to the subsequent film covering and packaging process through the conveyor belt for further processing.

[0022] Compared with the prior art, the beneficial effects of the present invention are: 1. A flattening component is provided. The operator places the stacked rock wool board body on the top of the top plate, rotates the double-headed screw rod, and the double-headed screw rod drives two L-shaped plates to approach, so that the L-shaped plates on both sides are close to the front and back sides of the rock wool board body. Then, the conveyor belt is started to convey, and the conveyor belt drives the fixed box and the top plate to move, thereby driving the stacked rock wool board body to move. When the contact plate moves to the position of the arc-shaped block, the operator starts the electric push rod to work. Since the elastic coefficient of the second spring is greater than that of the first spring, the arc-shaped block blocks the contact plate and the top plate. The conveyor belt continues to drive the fixed box to move, and the top plate drives the moving block to move on the fixed rod and compress the first spring. At the same time, the moving block drives the sliding rod and the piston plate to move through the connecting bar. Check valves are installed on the outer sides of the air inlet pipe and the air outlet pipe to achieve one-way conduction. The piston plate sucks air through the air inlet pipe. When the first spring is compressed to the limit, the contact plate will squeeze the arc-shaped block, and the arc-shaped block compresses the second spring and slides into the sliding sleeve. At this time, the elastic force of the first spring drives the moving block and the top plate to reset, and the moving block drives the connecting bar and the sliding rod to reset. The sliding rod drives the piston plate to squeeze the air inside the temporary storage box, so that the gas is discharged through the air outlet pipe and the nozzle, thereby slowing down the reset speed of the connecting bar and the moving block and preventing the instantaneous reset from causing the stacked rock wool board body to be uneven. During the time from the start of compression of the first spring to the compression limit, the positions of the top plate and the rock wool board body remain unchanged. During this period, the electric push rod drives the partition plate and the extrusion plate to squeeze and flatten the front and back sides of the rock wool board body, reducing the protrusion and unevenness of the stacked rock wool board body, facilitating the subsequent packaging operation of the rock wool board body. When the partition plate drives the extrusion plate to squeeze the rock wool board body, the extrusion plate first contacts the rock wool board body, and then the partition plate continues to compress the third spring and drives the inclined rod to unfold. The inclined rod stretches the fourth spring. The unfolding of the inclined rod plays a role in spreading the extrusion force and maintaining the stable extrusion of the extrusion plate on the rock wool board body. The L-shaped plate will block the partition plate to avoid excessive extrusion of the extrusion plate. The flattened rock wool board body is conveyed by the conveyor belt to the subsequent film covering and packaging process for further processing, solving the problem that the bottom rock wool board may shift along the conveyor belt direction with the upper rock wool board, resulting in unevenness of the sorted rock wool board and reducing the effect of subsequent film covering, packaging and transportation. 2. An auxiliary component is provided. When the conveyor belt drives the rock wool board body to move, the right side of the rock wool board body will contact the auxiliary roller. The rock wool board body drives the auxiliary roller and the vertical plate to rotate and unfold around the connecting plate. The vertical plate drives the fixed frame to rotate, and the cross bar slides inside the fixed frame. The cross bar drives the lower plate to rotate around the mounting piece, so that the auxiliary roller and the baffle can squeeze and flatten the left and right sides of the rock wool board body. Coupled with the front and back squeezing and flattening of the flattening component, the overall flatness of the rock wool board body is improved, which is beneficial to the subsequent film covering and packaging use.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 - 5 , the present invention provides a technical solution: an automatic stacking and packaging machine for rock wool board production, including an outer box body 1, a rock wool board main body 4, and supporting feet 2 symmetrically and fixedly installed at the bottom of the outer box body 1. A conveyor belt 3 is installed below the inner part of the outer box body 1.

[0027] Flattening components 5 are evenly arranged on the top of the conveyor belt 3. The flattening components 5 include a moving unit, a buffering unit, and an extrusion unit. The cooperation of the moving unit and the extrusion unit facilitates maintaining a stationary state when extruding and flattening the rock wool board main body 4, thereby reducing the situation of the upper and lower layers of the rock wool board main body 4 shifting due to the conveying of the conveyor belt 3, and facilitating subsequent film covering and packaging processing of the rock wool board main body 4.

[0028] The moving unit includes a fixed box 51 fixedly installed on the surface of the conveyor belt 3. A top plate 52 is slidably installed on the top of the fixed box 51. Contact plates 53 are symmetrically and fixedly connected to the front and rear sides of the top plate 52. L-shaped plates 55 are symmetrically installed on the top of the top plate 52, and the distance between the two L-shaped plates 55 is adjustable. Two fixed rods 57 are symmetrically and fixedly connected to the inner side of the fixed box 51. A moving block 58 is slidably connected to the outer side of the fixed rod 57. The tops of the two moving blocks 58 are fixedly connected to the top plate 52. A first spring 59 is sleeved on the outer side of the fixed rod 57.

[0029] A double-headed lead screw 54 is rotatably installed on the top of the top plate 52. The two L-shaped plates 55 are respectively located on the outer sides of the double-headed lead screw 54. The L-shaped plates 55 are threadedly connected to the double-headed lead screw 54. The first spring 59 is located on the side of the moving block 58 close to the double-headed lead screw 54. The two ends of the first spring 59 are respectively fixedly connected to the moving block 58 and the inner side wall of the fixed box 51.

[0030] The buffering unit includes temporary storage boxes 510 symmetrically and fixedly installed inside the fixed box 51. A sliding rod 511 is slidably connected to one side of the temporary storage box 510. One end of the sliding rod 511 is fixedly connected to a piston plate 512. The piston plate 512 fits against the inner wall of the temporary storage box 510 and is slidably connected to the temporary storage box 510. A connecting bar 513 is fixedly connected to one side of the moving block 58. The other end of the sliding rod 511 passes through the temporary storage box 510 and is fixedly connected to the connecting bar 513. The elastic coefficients of the two second springs 523 are greater than those of the two first springs 59.

[0031] An air inlet pipe 514 is installed on the outer side of the temporary storage box 510, and an air outlet pipe 515 is installed on the other outer side of the temporary storage box 510. The air inlet pipe 514 and the air outlet pipe 515 are located on the side of the temporary storage box 510 away from the connecting bar 513. Both the air inlet pipe 514 and the air outlet pipe 515 are communicated with the inside of the temporary storage box 510. Check valves are installed on the outer sides of both the air inlet pipe 514 and the air outlet pipe 515. One end of the air outlet pipe 515 away from the temporary storage box 510 is connected to a spray head 516, and the spray head 516 is fixedly installed on one side of the moving block 58.

[0032] The extrusion unit includes two symmetrically arranged mounting plates 517. The two mounting plates 517 are respectively fixedly connected to the front and rear inner walls of the outer box body 1. Electric push rods 518 are symmetrically and fixedly installed on the outer sides of the mounting plates 517. The model of the electric push rod 518 is YMD-606. The telescopic end of the electric push rod 518 is fixedly connected to a partition plate 520. A pressing plate 521 is installed on one side of the partition plate 520. A sliding sleeve 522 is fixedly connected to the lower part of the outer side of the mounting plate 517. A second spring 523 is fixedly connected inside the sliding sleeve 522. One side of the second spring 523 is fixedly connected to an arc-shaped block 524.

[0033] There are no less than two electric push rods 518. The bottom height of the partition plate 520 is lower than the top height of the L-shaped plate 55. An inner rod 519 is slidably connected inside the partition plate 520. The inner rod 519 is fixedly connected to the pressing plate 521. The horizontal height of the arc-shaped block 524 is the same as that of the contact plate 53. A third spring 525 is sleeved on the outer side of the inner rod 519. The third spring 525 is fixedly installed between the partition plate 520 and the pressing plate 521. An inclined rod 526 is rotatably connected to one side of the partition plate 520 close to the pressing plate 521. A fourth spring 527 is fixedly connected between the outer side of the inclined rod 526 and the pressing plate 521. There are no less than two inclined rods 526.

[0034] Example 1: As Figure 1 and Figures 6 - 12 shown, the operator places the stacked rock wool board body 4 on the top of the top plate 52, rotates the double-headed lead screw 54, and the double-headed lead screw 54 drives the two L-shaped plates 55 to approach, so that the L-shaped plates 55 on both sides are tightly attached to the front and rear sides of the rock wool board body 4. Then start the conveyor belt 3 to convey, and the conveyor belt 3 drives the fixed box 51 and the top plate 52 to move, thereby driving the stacked rock wool board body 4 to move.

[0035] When the contact plate 53 moves to the position of the arc-shaped block 524, the operator starts the electric push rod 518 to work. Since the elastic coefficient of the second spring 523 is greater than that of the first spring 59, that is, under the same deformation, the elastic force of the second spring 523 is greater than that of the first spring 59, the arc-shaped block 524 blocks the contact plate 53 and the top plate 52. The conveyor belt 3 continues to drive the fixed box 51 to move, and the top plate 52 drives the moving block 58 to move on the fixed rod 57 and compress the first spring 59. At the same time, the moving block 58 drives the sliding rod 511 and the piston plate 512 to move through the connecting bar 513. Check valves are installed on the outer sides of the intake pipe 514 and the exhaust pipe 515 to achieve one-way conduction. The piston plate 512 sucks air through the intake pipe 514. When the first spring 59 is compressed to the limit, the contact plate 53 will squeeze the arc-shaped block 524, and the arc-shaped block 524 compresses the second spring 523 and slides into the sliding sleeve 522. At this time, the elastic force of the first spring 59 drives the moving block 58 and the top plate 52 to reset, and the moving block 58 drives the connecting bar 513 and the sliding rod 511 to reset. The sliding rod 511 drives the piston plate 512 to squeeze the air inside the temporary storage box 510, so that the gas is discharged through the exhaust pipe 515 and the nozzle 516, thereby slowing down the reset speed of the connecting bar 513 and the moving block 58 and preventing the instant reset from causing the rock wool board body 4 to be stacked unevenly.

[0036] During the time from the start of compression of the first spring 59 to the compression limit, the positions of the top plate 52 and the rock wool board body 4 remain unchanged. During this period, the electric push rod 518 drives the partition plate 520 and the extrusion plate 521 to squeeze and flatten the front and rear sides of the rock wool board body 4, reducing the protrusion and unevenness of the stacked rock wool board body 4, facilitating the subsequent packaging operation of the rock wool board body 4. When the partition plate 520 drives the extrusion plate 521 to squeeze the rock wool board body 4, the extrusion plate 521 contacts the rock wool board body 4 first, and then the partition plate 520 continues to compress the third spring 525 and drives the inclined rod 526 to unfold. The inclined rod 526 stretches the fourth spring 527. The unfolding of the inclined rod 526 plays a role in spreading the extrusion force and maintaining the stable extrusion of the extrusion plate 521 on the rock wool board body 4. Before the first spring 59 resets, the electric push rod 518 is started to reset and contract to prevent hindering the subsequent conveying of the rock wool board body 4. The L-shaped plate 55 will block the partition plate 520 to avoid excessive extrusion of the extrusion plate 521. The flattened rock wool board body 4 is conveyed by the conveyor belt 3 to the subsequent film covering and packaging process for further processing.

[0037] On one side of the inner top surface of the outer box body 1, an auxiliary component 6 is provided. The auxiliary component 6 includes symmetrically arranged connecting plates 61 and mounting pieces 65. The connecting plates 61 and the mounting pieces 65 are both fixedly connected to one side of the inner top surface of the outer box body 1. A vertical plate 62 is rotatably connected between the two connecting plates 61. The vertical plate 62 is vertically arranged, and an auxiliary roller 63 is rotatably installed in a groove on one side of the vertical plate 62.

[0038] The auxiliary rollers 63 are evenly arranged from top to bottom, and there are at least four auxiliary rollers 63. On one side of the vertical plate 62 close to the mounting piece 65, a fixed frame 64 is symmetrically and fixedly connected.

[0039] A lower plate 66 is rotatably connected between the two mounting pieces 65. On the side of the lower plate 66 away from the mounting piece 65, a cross bar 67 is fixedly connected. The cross bar 67 is slidably connected to the two fixed frames 64, and stoppers are fixedly connected to both ends of the cross bar 67.

[0040] Embodiment 2: As Figures 13 - 14 shown, when the conveyor belt 3 drives the rock wool board main body 4 to move, the right side of the rock wool board main body 4 will contact the auxiliary roller 63. The rock wool board main body 4 drives the auxiliary roller 63 and the vertical plate 62 to rotate and unfold with the connecting plate 61 as the center. The vertical plate 62 drives the fixed frame 64 to rotate, and the cross bar 67 slides inside the fixed frame 64. And the cross bar 67 drives the lower plate 66 to rotate with the mounting piece 65 as the center, so that the auxiliary roller 63 and the baffle 56 can squeeze and flatten the left and right sides of the rock wool board main body 4. Then, with the front and back squeezing and flattening of the flattening assembly 5, the overall flatness of the rock wool board main body 4 is improved, which is beneficial to the subsequent film covering and packaging use.

[0041] Working principle: When using this device, first, as Figures 1 - 14 shown, the operator places the stacked rock wool board main bodies 4 on the top of the top plate 52. The L-shaped plates 55 on both sides are close to the front and back sides of the rock wool board main body 4. When the conveyor belt 3 drives the rock wool board main body 4 to move, the right side of the rock wool board main body 4 will contact the auxiliary roller 63. The auxiliary roller 63 and the baffle 56 can squeeze and flatten the left and right sides of the rock wool board main body 4. When the contact plate 53 moves to the position of the arc-shaped block 524, the operator starts the electric push rod 518 to work. The top plate 52 drives the moving block 58 to move on the fixed rod 57 and compress the first spring 59. During the time when the first spring 59 starts to be compressed to the compression limit, the electric push rod 518 drives the partition plate 520 and the extrusion plate 521 to squeeze and flatten the front and back sides of the rock wool board main body 4, reducing the situation of protrusion and unevenness in the stacking of the rock wool board main body 4, facilitating the subsequent packaging operation of the rock wool board main body 4. And when the partition plate 520 drives the extrusion plate 521 to squeeze the rock wool board main body 4, the extrusion plate 521 first contacts the rock wool board main body 4, and then the partition plate 520 continues to compress the third spring 525 and drives the inclined rod 526 to unfold. The inclined rod 526 stretches the fourth spring 527. The unfolding of the inclined rod 526 plays a role in spreading the extrusion force, maintaining the stable extrusion of the extrusion plate 521 on the rock wool board main body 4. The L-shaped plate 55 will block the partition plate 520 to avoid excessive extrusion of the extrusion plate 521. The flattened rock wool board main body 4 is conveyed by the conveyor belt 3 to the subsequent film covering and packaging process for further processing.

9. An operating method of an automatic plate stacking and packaging machine for rock wool board production, characterized in that, For an automatic plate stacking and packaging machine for rock wool board production as described in claim 8, the operation steps are as follows: Step 1: The operator places the stacked main body of the rock wool board (4) on the top of the top plate (52), rotates the double-headed screw rod (54), and the double-headed screw rod (54) drives two L-shaped plates (55) to approach, so that the L-shaped plates (55) on both sides are tightly attached to the front and back sides of the main body of the rock wool board (4). Then, the conveyor belt (3) is started to convey, and the conveyor belt (3) drives the fixed box (51) and the top plate (52) to move, thereby driving the stacked main body of the rock wool board (4) to move; Step 2: When the conveyor belt (3) drives the main body of the rock wool board (4) to move, the right side of the main body of the rock wool board (4) will contact the auxiliary roller (63). The main body of the rock wool board (4) drives the auxiliary roller (63) and the vertical plate (62) to rotate and unfold around the connecting plate (61). The vertical plate (62) drives the fixed frame (64) to rotate. The cross bar (67) slides inside the fixed frame (64), and the cross bar (67) drives the lower plate (66) to rotate around the mounting piece (65), so that the auxiliary roller (63) and the baffle (56) cooperate to squeeze and flatten the left and right sides of the main body of the rock wool board (4); Step 3: When the contact plate (53) moves to the position of the arc-shaped block (524), the operator starts the electric push rod (518) to work. Since the elastic coefficient of the second spring (523) is greater than that of the first spring (59), the arc-shaped block (524) blocks the contact plate (53) and the top plate (52). The conveyor belt (3) continues to drive the fixed box (51) to move, and the top plate (52) drives the moving block (58) to move on the fixed rod (57) and compress the first spring (59). The moving block (58) simultaneously drives the sliding rod (511) and the piston plate (512) to move through the connecting bar (513). Check valves are installed on the outer sides of the air inlet pipe (514) and the air outlet pipe (515) to achieve one-way conduction. The piston plate (512) sucks air through the air inlet pipe (514). When the first spring (59) is compressed to the limit, the contact plate (53) will squeeze the arc-shaped block (524), and the arc-shaped block (524) compresses the second spring (523) and slides into the sliding sleeve (522). At this time, the elastic force of the first spring (59) drives the moving block (58) and the top plate (52) to reset, and the moving block (58) drives the connecting bar (513) and the sliding rod (511) to reset. The sliding rod (511) drives the piston plate (512) to squeeze the air inside the temporary storage box (510), so that the gas is discharged through the air outlet pipe (515) and the nozzle (516), thereby slowing down the reset speed of the connecting bar (513) and the moving block (58) and preventing the stacked main body of the rock wool board (4) from being uneven due to instantaneous reset; Step 4: During the time when the first spring (59) starts to be compressed to the compression limit, the electric push rod (518) drives the partition plate (520) and the extrusion plate (521) to squeeze and flatten the front and back sides of the main body of the rock wool board (4), reducing the situation of the stacked main body of the rock wool board (4) protruding unevenly, facilitating the subsequent packaging operation of the main body of the rock wool board (4). The L-shaped plate (55) will block the partition plate (520) to prevent the extrusion plate (521) from over-extruding. The flattened main body of the rock wool board (4) is conveyed by the conveyor belt (3) to the subsequent film covering and packaging process for continuous processing.
