Description

Technical Field

[0001] The invention relates to the technical field of ceramic processing equipment, in particular to a high-efficiency foam ceramic plate unloading machine. Background Art

[0002] Foam ceramic boards are made of industrial waste and inorganic foaming agents and other raw materials through high-temperature sintering. They are a new type of energy-saving and environmentally friendly material in recent years. They can be widely used in building partitions, exterior wall insulation and other fields. They are generally fired in a multi-layer kiln car-type tunnel kiln.

[0003] In the prior art, a utility model patent with authorization announcement number CN209127600U discloses a high-efficiency unloading machine for multi-layer foam ceramic boards, which includes a frame, a first clamping plate mechanism for clamping the foam ceramic boards, a pallet translation mechanism that continuously extends in and out from under the first clamping plate mechanism, a sliding roller mechanism that supports the pallet translation mechanism, a second clamping plate mechanism for clamping the foam ceramic boards, and a lifting mechanism installed on the frame; the first clamping plate mechanism, the pallet translation mechanism and the sliding roller mechanism are respectively connected to the lifting mechanism; the sliding roller mechanism includes two groups of wheels that are close to or far away from each other, and when the distance between the two groups of wheels is shortest, the wheels support the pallet translation mechanism.

[0004] During the unloading process, the first clamping mechanism clamps and lifts the foam ceramic plate on the kiln car; then the synchronous belt of the plate translation mechanism translates to the bottom of the foam ceramic plate and is supported by the supporting wheel of the sliding supporting wheel mechanism. After the first clamping mechanism releases the foam ceramic plate, the synchronous belt sends the foam ceramic plate out; then, the second clamping mechanism moves to the top of the synchronous belt, and through the lifting action, the second clamping mechanism clamps the foam ceramic plate and transports it away.

[0005] However, in order to enable the first clamping plate mechanism to lift up by clamping the foam ceramic plate and the support plate translation mechanism to translate to the bottom of the foam ceramic plate, certain requirements are placed on the structure of the kiln car, that is, the height spacing between the adjacent upper and lower foam ceramic plates on the kiln car needs to be set larger. As a result, the number of foam ceramic plates that can be placed on the kiln car is relatively small, resulting in a lower production efficiency of the foam ceramic plates. Summary of the invention

[0006] The object of the present invention is to provide a high-efficiency foam ceramic board unloading machine to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0007] The technical solutions adopted to solve the above technical problems are:

[0008] The present invention provides a high-efficiency board unloading machine for foam ceramic boards, and the high-efficiency board unloading machine comprises:

[0009] The clamping mechanism comprises a clamping short arm, a clamping long arm and a clamping driving mechanism, wherein the clamping short arm and the clamping long arm are arranged opposite to each other on the left and right sides, and the clamping short arm and the clamping long arm can be horizontally close to each other to clamp the foam ceramic plate, and the clamping driving mechanism is used to drive the clamping short arm and the clamping long arm to move;

[0010] A first lifting frame connected to the clamping mechanism, wherein the first lifting frame can move in an up-down direction, and the clamping mechanism can move in a left-right direction;

[0011] A translation driving mechanism, which is arranged on the first lifting frame, and is used to drive the clamping mechanism to move;

[0012] frame;

[0013] A first driving mechanism, which is disposed on the frame and is used to drive the first lifting frame to move up and down;

[0014] A second lifting frame, which can move in an up-down direction;

[0015] A second driving mechanism, which is disposed on the frame and is used to drive the second lifting frame to move up and down;

[0016] The conveying mechanism is arranged on the second lifting frame, and the clamping short arm is located between the clamping long arm and the conveying mechanism.

[0017] The present invention has at least the following beneficial effects: the clamping mechanism uses the clamping drive mechanism to drive the clamping short arm and the clamping long arm to move closer to or away from each other, thereby being able to stably clamp or release the foam ceramic plate. After the clamping mechanism clamps the foam ceramic plate on the kiln car, through the setting of the translation drive mechanism, the conveying mechanism and the clamping long arm, the length of the clamping long arm is greater than the length of the kiln car, so that the translation drive mechanism can drive the clamping mechanism to clamp the foam ceramic plate and move horizontally in the direction of the conveying mechanism, and place the foam ceramic plate on the conveying mechanism, and the conveying mechanism conveys the foam ceramic plate outward. In addition, a first lifting frame, a first driving mechanism, a second lifting frame and a second driving mechanism are also provided. When the first driving mechanism and the second driving mechanism are working, the clamping mechanism and the translation drive mechanism move up and down with the first lifting frame, and the conveying mechanism moves up and down with the second lifting frame, so that the multi-layer foam ceramic plates arranged along the height direction on the kiln car can be unloaded one by one.

[0018] The clamping mechanism having a short clamping arm and a long clamping arm moves horizontally after clamping the foam ceramic plate, and places the foam ceramic plate on the conveying mechanism to complete the plate unloading work. Compared with the existing technology, the height spacing between the adjacent upper and lower layers of foam ceramic plates on the kiln car can be set smaller, so that more foam ceramic plates can be placed on the kiln car along the height direction, thereby improving the production efficiency of the foam ceramic plates.

[0022] A telescopic cylinder is provided, and the two ends of the telescopic cylinder are respectively connected to the clamping short arm and the clamping long arm. When the telescopic rod of the telescopic cylinder is extended or retracted, the clamping short arm and the clamping long arm can move away from or close to each other, thereby loosening or clamping the foam ceramic plate. Such a design has the advantages of simple structure, low cost and low energy consumption. A moving frame is provided, and the moving frame is connected to the clamping short arm and the clamping long arm, so that the clamping short arm and the clamping long arm can move horizontally together with the moving frame.

[0023] As a further improvement of the above technical solution, the first lifting frame is provided with a guide rail, the mobile frame is provided with a pulley, and the pulley is connected to the guide rail. The pulley is provided on the mobile frame, and the guide rail is correspondingly provided on the first lifting frame. When the translation drive mechanism drives the mobile frame to move horizontally, the mobile frame can move back and forth along the guide rail through the rolling connection between the pulley and the guide rail. The use of the rolling connection method can reduce the friction between the mobile frame and the first lifting frame, thereby reducing the energy consumption of the translation drive mechanism.

[0024] As a further improvement of the above technical solution, the translation drive mechanism includes:

[0025] A fixed chain, a left end of which is connected to the left end of the first lifting frame, and a right end of which is connected to the right end of the first lifting frame;

When the driving motor on the mobile frame is running, the driving sprocket rotates, so that the mobile frame can move back and forth along the length direction of the fixed chain. This design has the advantages of stable and reliable operation and long travel.

[0029] As a further improvement of the above technical solution, the clamping short arm and / or the clamping long arm is provided with a slider, the mobile frame is provided with a long straight guide rail, and the slider is connected to the long straight guide rail.

[0082] Reference Figures 1 to 9 Several embodiments of the high-efficiency foam ceramic board unloading machine of the present invention are given below.

[0083] In the prior art, Figure 1 and Fig. 9 As shown, the kiln car 100 mainly includes a base, travel wheels 150 , columns 120 , beams 130 and a support plate 140 .

[0084] The walking wheel 150 is installed at the bottom of the base, and four columns 120 are provided. The four columns 120 are fixed on the base and arranged in a 2×2 array, and the length direction of the columns 120 is consistent with the Z axis. In this embodiment, the kiln car 100 moves along the Y axis, and six beams 130 are provided. The length direction of the beams 130 is consistent with the X axis, and the two ends of the beams 130 are respectively connected to the columns 120. The support plate 140 can be a boron plate, and there are three support plates 140. The support plate 140 is arranged on the beam 130 to carry the foam ceramic plate 110, and the support plate 140 is supported by two beams 130.

[0085] Of course, when the kiln car 100 moves along the X-axis direction, the length direction of the beam 130 is consistent with the Y-axis.

[0086] like Figures 1 to 8 As shown, an embodiment of the present invention provides a high-efficiency board unloading machine for foam ceramic boards, which includes: a clamping mechanism 400, a first lifting frame 200, a translation drive mechanism 500, a frame 900, a first drive mechanism 300, a second lifting frame 600, a second drive mechanism 700 and a conveying mechanism 800.

[0087] The frame 900 may be welded from a plurality of metal rods, and mainly plays a supporting role.

[0088] The clamping mechanism 400 includes a clamping short arm 420 , a clamping long arm 410 and a clamping driving mechanism.

[0089] The clamping short arm 420 and the clamping long arm 410 are arranged opposite to each other on the left and right sides, and the clamping short arm 420 and the clamping long arm 410 can be horizontally close to each other to clamp the foam ceramic plate.

[0090] In this embodiment, the short clamping arm 420 is in a U-shaped structure, and the long clamping arm 410 is in a U-shaped structure, both of which are connected by metal rods, such as Figure 1 As shown. Of course, the clamping short arm 420 and the clamping long arm 410 can also be in an L-shaped structure. The clamping short arm 420 and the clamping long arm 410 can both be provided with a buffer pad such as a rubber pad. When the clamping short arm 420 and the clamping long arm 410 clamp the foam ceramic board 110, the foam ceramic board 110 can be prevented from being damaged by the buffer pad.

[0091] The kiln car 100 moves along the Y-axis direction, and the clamping short arm 420 can be set on the left, and the clamping long arm 410 can be set on the right. Since the length of the clamping long arm 410 is greater than the length of the kiln car 100, when the clamping short arm 420 and the clamping long arm 410 are close to each other and clamp the foam ceramic plate 110 on the kiln car 100, if the clamping mechanism 400 is moved to the left, the foam ceramic plate 110 can be removed from the kiln car 100.

[0092] The clamping driving mechanism is used to drive the clamping short arm 420 and the clamping long arm 410 to move, so as to clamp or release the foam ceramic plate 110 .

[0093] Specifically, Figure 3 and Figure 4 As shown, the clamping drive mechanism includes: a telescopic cylinder 430 and a moving frame 440.

[0094] One end of the telescopic cylinder 430 is connected to the clamping long arm 410, and the other end of the telescopic cylinder 430 is connected to the clamping short arm 420. In this embodiment, the fixed end of the telescopic cylinder 430 is connected to the clamping long arm 410 by bolts, and the telescopic rod of the telescopic cylinder 430 is connected to the clamping short arm 420 by bolts.

[0095] When the telescopic rod of the telescopic cylinder 430 is extended, the clamping short arm 420 and the clamping long arm 410 can move away from each other, thereby releasing the foam ceramic board 110; when the telescopic rod of the telescopic cylinder 430 is retracted, the clamping short arm 420 and the clamping long arm 410 can move closer to each other, thereby clamping the foam ceramic board 110. Such a design has the advantages of simple structure, low cost and low energy consumption.

[0096] The moving frame 440 is connected to the first lifting frame 200, and the clamping short arm 420 and the clamping long arm 410 are respectively connected to the moving frame 440. The moving frame 440 can be formed by a plurality of metal square rods connected in a crisscross manner.

[0097] More specifically, the clamping short arm 420 is provided with a slider 470, and the movable frame 440 is correspondingly provided with a long straight guide rail, the two ends of the long straight guide rail are extended left and right, the slider 470 is connected to the long straight guide rail, and the clamping long arm 410 is fixedly connected to the movable frame 440 by bolts. When the telescopic cylinder 430 is working, the clamping short arm 420 moves, while the clamping long arm 410 remains stationary.

[0098] In addition, a slider 470 may be provided on the clamping long arm 410, and a long straight guide rail may be provided correspondingly on the movable frame 440. The two ends of the long straight guide rail may be extended left and right. The slider 470 may be connected to the long straight guide rail, and the clamping short arm 420 may be fixedly connected to the movable frame 440 by bolts. When the telescopic cylinder 430 is working, the clamping long arm 410 may move, while the clamping short arm 420 may remain stationary.

[0099] In addition, both the clamping short arm 420 and the clamping long arm 410 are provided with a slider 470, and the movable frame 440 is correspondingly provided with a long straight guide rail, the two ends of the long straight guide rail are extended left and right, and the slider 470 is connected to the long straight guide rail. When the telescopic cylinder 430 is working, the clamping short arm 420 and the clamping long arm 410 move together.

[0100] In this embodiment, four clamping mechanisms 400 are provided, such as Figure 4 As shown, the number of the clamping mechanisms 400 is selected according to actual conditions.

[0101] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the translation driving mechanism 500 is disposed on the first lifting frame 200 , and the translation driving mechanism 500 is used to drive the clamping mechanism 400 to move.

[0102] Specifically, the translation driving mechanism 500 includes: a fixed chain 540 , a driving motor 510 and a driving sprocket 520 .

[0103] The left end of the fixed chain 540 is connected to the left end of the first lifting frame 200 , and the right end of the fixed chain 540 is connected to the right end of the first lifting frame 200 , so that the fixed chain 540 is fixed to the first lifting frame 200 .

[0104] The driving motor 510 is connected to the moving frame 440 by bolts, and can move left and right together with the moving frame 440. The driving motor 510 is a forward and reverse motor, and the output shaft of the driving motor 510 can rotate clockwise or counterclockwise.

[0105] The driving sprocket 520 is connected to the output shaft of the driving motor 510, and the driving sprocket 520 is meshed with the fixed chain 540. When the output shaft of the driving motor 510 drives the driving sprocket 520 to rotate, the driving sprocket 520 and the fixed chain 540 mesh together, so that the moving frame 440 can move back and forth along the length direction of the fixed chain 540. Such a design has the advantages of stable and reliable operation and long travel.

[0106] In this embodiment, the driving motor 510 is transmission-connected to a power shaft 511 , and driving sprockets 520 are respectively provided at both ends of the power shaft 511 . Correspondingly, two fixed chains 540 are provided.

[0107] In addition, a tensioning sprocket 530 can be set on the left and right sides of the driving sprocket 520. The tensioning sprocket 530 can be installed on the movable frame 440. Through the meshing connection between the tensioning sprocket 530 and the fixed chain 540, the fixed chain 540 and the driving sprocket 520 are meshed more closely, and the transmission effect is better.

[0108] Of course, a telescopic cylinder may also be used to drive the movable frame 440 to move left and right. Alternatively, a rack and pinion transmission mode may be used to replace the fixed chain 540 with a rack.

[0109] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first lifting frame 200 can be formed by connecting a plurality of metal square rods in a crisscross pattern. The first lifting frame 200 is connected to the clamping mechanism 400, and the first lifting frame 200 can move along the up and down direction with the clamping mechanism 400, so as to unload the multi-layer foam ceramic panels 110 on the kiln car 100 one by one.

[0110] The first lifting frame 200 is provided with a first guide wheel 220, and the frame 900 is provided with a first slide groove, which extends along the Z axis. The first guide wheel 220 is arranged in the first slide groove, and the first slide groove plays a limiting role on the first guide wheel 220, so that the first lifting frame 200 can move up and down smoothly without shaking.

[0111] Also, the clamping mechanism 400 can move in the left-right direction.

[0112] Specifically, the first lifting frame 200 is provided with a guide rail 210, and both ends of the guide rail 210 are extended to the left and right, and the cross-sectional shape of the guide rail 210 can be square or triangular. The guide rail 210 can be provided on the top of the first lifting frame 200, and the top of the moving frame 440 is provided with a connecting rod 460, and the connecting rod 460 is provided with a pulley 450, and the pulley 450 can be an H-type roller or a V-type roller, and the pulley 450 is connected to the guide rail 210.

[0113] When the translation drive mechanism 500 drives the moving frame 440 to move horizontally, the rolling connection between the pulley 450 and the guide rail 210 enables the moving frame 440 to move back and forth along the guide rail 210. The rolling connection method can reduce the friction between the moving frame 440 and the first lifting frame 200, thereby reducing the energy consumption of the translation drive mechanism 500.

[0114] Of course, a slider may be used instead of the pulley 450 .

[0115] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the first driving mechanism 300 is disposed on the frame 900 , and the first driving mechanism 300 is used to drive the first lifting frame 200 to move up and down.

Further, the first counterweight 340 is provided with a first guide roller 341, the frame 900 is provided with a first guide groove, the first guide groove is extended along the Z axis, the first guide roller 341 is disposed in the first guide groove, the rolling surface of the first guide roller is in contact with the side wall surface of the first guide groove, and the first guide groove has a limiting effect on the first guide roller 341, so that the first counterweight 340 can be lifted and lowered smoothly without shaking.

[0118] The lower end of the first left chain 350 is fixedly connected to the left end of the first lifting frame 200, and the lower end of the first right chain 360 is fixedly connected to the right end of the first lifting frame 200. Under the traction of the first left chain 350 and the first right chain 360, the first lifting frame 200 can move in the up and down direction.

[0121] like Figure 6 As shown, when the first motor 310 drives the first active sprocket 320 to rotate clockwise, the first counterweight 340 moves upward under the pulling force of the first active chain 330, and correspondingly, the lower ends of the first left chain 350 and the first right chain 360 bring the first lifting frame 200 down.

[0122] When the first motor 310 drives the first driving sprocket 320 to rotate counterclockwise, the lower ends of the first left chain 350 and the first right chain 360 rise with the first lifting frame 200 under the pulling force of the first driving chain 330, and correspondingly, the first counterweight block 340 descends.

[0123] The use of the first counterweight 340 can effectively reduce the load of the first motor 310 .

[0124] The first right sprocket 380 is mounted at the right end of the frame 900. The first right sprocket 380 is meshed with the first right chain 360 and can change the direction of the first right chain 360. Figure 6 shown.

[0125] The first left sprocket 372 is mounted on the left end of the frame 900, and the first left sprocket 372 is meshed with the first left chain 350. In addition, the first middle sprocket 371 is mounted on the frame 900 and is located between the first left sprocket 372 and the first right sprocket 380, and the first middle sprocket 371 is meshed with the first left chain 350.

[0126] Of course, a first tensioning wheel 390 can also be provided, and the first tensioning wheel 390 is installed on the frame 900. The first tensioning wheel 390 is meshed and connected with the first driving chain 330. The first tensioning wheel 390 is located above the first driving chain 330 and can exert a downward pressure on the first driving chain 330, so that the first driving chain 330 and the first driving sprocket 320 are more closely meshed and the transmission efficiency is better.

Correspondingly, two first driving chains 330, two first left chains 350 and two first right chains 360 are respectively provided, and the two first left chains 350 and the two first right chains 360 are respectively connected to the four corners of the first lifting frame 200.

[0128] Of course, in addition to the first driving mechanism 300 of the above structure, a hydraulic cylinder or a screw transmission mechanism can also be used to drive the first lifting frame 200 to move upward or downward.

[0129] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the second lifting frame 600 can move in the up and down direction. The second lifting frame 600 can be formed by connecting a plurality of metal square bars in a crisscross manner.

[0130] The second lifting frame 600 is provided with a second guide wheel 610, and the frame 900 is provided with a second slide groove, which is extended along the Z axis. The second guide wheel 610 is arranged in the second slide groove, and the second slide groove plays a limiting role on the second guide wheel 610, so that the second lifting frame 600 can move up and down smoothly without shaking.

[0131] The second driving mechanism 700 is disposed on the frame 900 and is used to drive the second lifting frame 600 to move up and down;

[0132] Specifically, the second driving mechanism 700 includes: a second counterweight block 740 , a second left chain 750 , a second right chain 760 , a second driving chain 730 , a second driving sprocket 720 , a second motor 710 , a second right sprocket 780 , a second left sprocket 772 and a second middle sprocket 771 .

[0133] The second counterweight 740 is arranged on the left side of the frame 900. Further, the second counterweight 740 is provided with a second guide roller, the frame 900 is provided with a second guide groove, the second guide groove is extended along the Z axis, the second guide roller is arranged in the second guide groove, the rolling surface of the second guide roller is in contact with the side wall surface of the second guide groove, and the second guide groove has a limiting effect on the second guide roller, so that the second counterweight 740 can be lifted and lowered smoothly without shaking.

[0134] The lower end of the second left chain 750 is fixedly connected to the left end of the second lifting frame 600, and the lower end of the second right chain 760 is connected to the right end of the second lifting frame 600. Under the traction of the second left chain 750 and the second right chain 760, the second lifting frame 600 can move in the up and down direction.

[0135] The lower end of the second active chain 730 may be connected to the second counterweight 740 by welding or bolts, and the upper end of the second left chain 750 and the upper end of the second right chain 760 may be connected to the upper end of the second active chain 730 by welding or bolts, respectively.

[0136] The second driving sprocket 720 is meshedly connected with the second driving chain 730. The second motor 710 is connected to the frame 900 by bolts, and the output shaft of the second motor 710 is connected to the second driving sprocket 720. The second motor 710 is a forward and reverse motor.

[0137] like Figure 8 As shown, when the second motor 710 drives the second active sprocket 720 to rotate clockwise, the second counterweight 740 moves upward under the pulling force of the second active chain 730, and correspondingly, the lower ends of the second left chain 750 and the second right chain 760 bring the second lifting frame 600 down.

[0138] When the second motor 710 drives the second driving sprocket 720 to rotate counterclockwise, the lower ends of the second left chain 750 and the second right chain 760 rise with the second lifting frame 600 under the pulling force of the second driving chain 730, and correspondingly, the second counterweight block 740 descends.

[0139] The use of the second counterweight 740 can effectively reduce the load of the second motor 710 .

[0140] The second right sprocket 780 is mounted at the right end of the frame 900. The second right sprocket 780 is meshed and connected with the second right chain 760, and can change the direction of the second right chain 760. Figure 8 shown.

In addition, the second middle sprocket 771 is mounted on the frame 900 and is disposed between the second left sprocket 772 and the second right sprocket 780, and the second middle sprocket 771 is meshed with the second left chain 750. The cooperation between the second left sprocket 772 and the second middle sprocket 771 can change the direction of the second left chain 750. Figure 8 shown.

[0142] Of course, a second tensioner 790 can also be provided. The second tensioner 790 is mounted on the frame 900. The second tensioner 790 is meshed and connected with the second driving chain 730. The second tensioner 790 is located above the second driving chain 730 and can exert a downward pressure on the second driving chain 730, so that the second driving chain 730 and the second driving sprocket 720 are more closely meshed and the transmission efficiency is better.

[0143] In this embodiment, if Figure 7As shown, the second motor 710 is connected to a second transmission shaft 711, and second driving sprockets 720 are respectively provided at both ends of the second transmission shaft 711. Correspondingly, two second driving chains 730, two second left chains 750 and two second right chains 760 are respectively provided, and the two second left chains 750 and the two second right chains 760 are respectively connected to the four corners of the second lifting frame 600.

[0144] Of course, in addition to the second driving mechanism 700 of the above structure, a hydraulic cylinder or a screw transmission mechanism can also be used to drive the second lifting frame 600 to move upward or downward.

[0145] The conveying mechanism 800 is installed on the second lifting frame 600 by bolts, and can move up and down together with the second lifting frame 600, so as to cooperate with the clamping mechanism 400 to unload the multi-layer foam ceramic plates 110 on the kiln car 100 one by one. The clamping short arm 420 is located between the clamping long arm 410 and the conveying mechanism 800.

[0146] In this embodiment, the conveying mechanism 800 is located on the left side of the clamping mechanism 400 , so that the clamping mechanism 400 can clamp the foam ceramic plate 110 and move to the left to place the foam ceramic plate 110 on the conveying mechanism 800 .

[0147] The conveying direction of the conveying mechanism 800 can be set along the X-axis or along the Y-axis. The conveying mechanism 800 can be connected with other conveying lines to transfer the unloaded foam ceramic plates 110 to other conveying lines.

[0148] Preferably, the conveying mechanism 800 is a belt conveyor, but it is not excluded that a roller conveyor, a chain conveyor, etc. may be used.

[0149] The working process of the high-efficiency plate unloading machine provided by the embodiment of the present invention is as follows:

[0150] When the kiln car 100 carrying the plurality of foam ceramic plates 110 moves to the right and into position, the kiln car 100 stops moving. At this time, the kiln car 100 is located between the clamping short arm 420 and the clamping long arm 410 .

[0151] Then, the first driving mechanism 300 works to drive the clamping mechanism 400 to descend together with the first lifting frame 200; after descending to a suitable position, the clamping driving mechanism drives the clamping short arm 420 and the clamping long arm 410 to approach each other, thereby effectively clamping the foam ceramic plate 110 on the kiln car 100.

[0152] At the same time, the second driving mechanism 700 works, driving the conveying mechanism 800 to descend together with the second lifting frame 600; after descending to a suitable position, the clamping mechanism 400 is driven by the translation driving mechanism 500 to move to the left with the foam ceramic plate 110. Since the length of the clamping long arm 410 is greater than the length of the kiln car 100, the clamping mechanism 400 can remove the foam ceramic plate 110 from the kiln car 100 by moving to the left.

[0153] When the clamping mechanism 400 moves to the left and is in place, the foam ceramic plate 110 is located above the conveying mechanism 800, and the clamping short arm 420 and the clamping long arm 410 move away from each other, releasing the foam ceramic plate 110, and causing the foam ceramic plate 110 to be placed on the conveying mechanism 800; then, the second lifting frame 600, under the action of the second driving mechanism 700, moves the conveying mechanism 800 up or down, thereby causing the conveying mechanism 800 to dock with other conveying lines and convey the unloaded foam ceramic plate 110 outward, thereby completing the unloading of a layer of foam ceramic plates 110 on the kiln car 100.

[0154] Subsequently, under the action of the first driving mechanism 300 and the second driving mechanism 700 , the clamping mechanism 400 and the conveying mechanism 800 continue to move downward, and the above steps are repeated to unload the next layer of foam ceramic plates 110 on the kiln car 100 .

[0155] The maximum horizontal distance between the clamping short arm 420 and the clamping long arm 410 is greater than the length of the kiln car 100. Therefore, when the clamping short arm 420 and the clamping long arm 410 move away from each other and rise with the first lifting frame 200, the kiln car 100 that has been unloaded (i.e., empty) can continue to move to the right, thereby enabling the efficient plate unloading machine to unload the next fully loaded kiln car 100.

[0156] Compared with the prior art, the present invention realizes the unloading of the foam ceramic plate on the kiln car 100 by the clamping mechanism 400 moving horizontally toward the conveying mechanism 800 after clamping the foam ceramic plate 110, and placing the foam ceramic plate 110 on the conveying mechanism 800. Such a design allows the height spacing between the adjacent upper and lower layers of foam ceramic plates 110 on the kiln car 100 to be set smaller, allowing the clamping long arm 410 to pass through, thereby facilitating the placement of more foam ceramic plates 110 on the kiln car 100 along the height direction, which is ultimately beneficial to improving the production efficiency of the foam ceramic plates 110.

[0157] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
