Abstract

This utility model relates to the technical field of insulation board production equipment, specifically to an insulation board transportation and palletizing device. It includes a frame fixedly installed on the ground, and an insulation board lifting mechanism, a conveying mechanism, and a pushing mechanism disposed within the frame. The lifting mechanism controls the vertical movement of the lifting frame via a drive component to adapt to different stacking height requirements. The conveying mechanism includes an active conveying component and a passive conveying component. The active component transports the insulation board to the middle of the conveying frame, while the passive component provides support and transition functions in the rear half of the conveying frame using a non-powered passive roller. The pushing mechanism controls the lifting and lowering of the pushing frame via an avoidance component to avoid interfering with the insulation board transportation. After the insulation board stops, the pushing component precisely pushes it into the curing frame. This not only converts sliding friction into rolling friction through the non-powered roller structure, significantly reducing surface damage to the insulation board and improving product qualification rate and equipment reliability, but also achieves efficient transportation and automated palletizing of the insulation board.

Description

Technical Field

[0001] This utility model relates to the technical field of insulation board production equipment, specifically to an insulation board transportation and stacking device. Technical Background

[0002] Insulation boards are boards with thermal insulation functions. During the production process of insulation boards, a certain thickness of reinforcing material is usually laminated to the surface of the insulation board to make surface-reinforced insulation boards, thereby enhancing the strength of the insulation boards and enabling them to be used more widely in the construction field.

[0003] In the manufacturing process of insulation boards, especially in the crucial step of transferring the surface-laminated insulation boards to the curing rack, manual handling is currently the primary method. However, this method not only significantly increases the labor intensity of workers and reduces work efficiency, making it difficult to adapt to the needs of automated continuous production, but also exposes workers to a high risk of accidental injury during the handling process.

[0004] To address the aforementioned issues, Chinese Utility Model Patent Application No. 201420860798.2 discloses a palletizing machine, comprising a frame structure and two motors for providing power. A support is provided at the bottom of the frame, and a horizontal conveyor frame is installed inside the frame. Corresponding drive shafts are located at the upper and lower ends of the frame on both sides of the conveyor frame. The conveyor frame is movably connected to guide rails on the inner side of the frame via sliders on both sides. The two sides of the conveyor frame are also connected to a longitudinal chain via connectors. Rollers are located at both ends of the conveyor frame, and the surfaces of the two rollers are connected by a transmission belt. The sprockets on both sides of the two rollers are also connected by a transverse chain. This enables the transportation and palletizing of insulation boards, improving work efficiency.

[0005] However, the aforementioned existing technology still has the following problems: Since the pusher plate is directly fixed on the conveyor belt, when the conveyor belt starts, stops, or the pusher plate applies force, relative sliding friction (rather than ideal static friction) is easily generated between the insulation board and the contact surface of the conveyor belt. This sliding friction, especially for insulation boards with composite coatings on the surface, can easily cause scratches, wear, or peeling of the coating, seriously affecting the product quality and appearance of the insulation board, and may reduce its service life. Utility Model Content

[0006] In view of this, it is necessary to provide an insulation board stacking device that can transport insulation boards to the curing rack for placement while reducing damage to the surface of the insulation boards.

[0007] An insulation board transport and stacking device includes a frame fixedly installed on the ground and an insulation board lifting mechanism, an insulation board conveying mechanism, and an insulation board pushing mechanism disposed in the frame; the insulation board lifting mechanism includes a lifting frame and a drive assembly, the lifting frame is disposed parallel to the ground inside the frame, and the drive assembly is disposed on the frame and fixedly connected to the lifting frame to drive the lifting frame to move up and down in a direction perpendicular to the ground; The insulation board conveying mechanism is located below the lifting frame and includes a conveying frame, an active conveying component, and a passive conveying component that are fixedly installed below the lifting frame. The conveying frame is parallel to the lifting frame. The active conveying component is located in the front half of the conveying frame to convey the insulation board from the front end to the middle. The passive conveying component is located in the rear half of the conveying frame to support and transition the insulation board conveyed by the active conveying component. The insulation board pushing mechanism is disposed between the lifting frame and the conveyor frame, and includes a pushing frame, a pushing component, and a clearance component disposed between the lifting frame and the conveyor frame. The pushing component is movably disposed on the pushing frame to push the insulation board that is resting on the passive conveyor component into the curing frame located on one side of the frame. During pushing, the insulation board is relatively stationary with the passive conveyor component or undergoes rolling friction. The clearance component is disposed on the lifting frame and connected to the pushing frame. It can lift the pushing frame before the insulation board enters the conveyor frame so that the pushing component can clear the insulation board. It can also lower the pushing frame after the insulation board stops on the passive conveyor component so that the pushing component can push the insulation board.

[0008] Preferably, the drive assembly includes a first drive shaft, a second drive shaft, a top lifting sprocket, a bottom lifting sprocket, a lifting motor, a first drive sprocket, a first driven sprocket, a second driven sprocket, a first chain, and a second chain. The top of the frame is provided with a first drive shaft and a second drive shaft parallel to the ground and located on both sides of the lifting frame. The top lifting sprocket is provided at both ends of the first and second drive shafts. The bottom of the frame is provided with a bottom lifting sprocket corresponding to the top lifting sprocket on each side. Each pair of top and bottom lifting sprockets on the same side are connected by a first chain. The lifting frame is fixedly connected to the first chain. The top of the frame is also provided with the lifting motor, on which the first drive sprocket is provided. The first driven sprocket is provided on the first drive shaft, and the second driven sprocket is provided on the second drive shaft. The first drive sprocket, the first driven sprocket, and the second driven sprocket are connected by a second chain, thereby driving the first drive sprocket to rotate via the lifting motor, causing the first and second drive shafts to rotate synchronously, and thus driving the first chain to move the lifting frame up and down.

[0009] Preferably, the active conveying assembly includes an active roller rotatably mounted on the conveyor frame and an active roller drive motor. The active rollers are evenly spaced from the front end to the middle region of the conveyor frame. Each active roller is equipped with a roller driven sprocket. The active roller drive motor is fixedly mounted on the conveyor frame and is equipped with a roller drive sprocket. The roller driven sprocket and the roller drive sprocket are connected by a chain drive so that the active roller is driven to rotate by the active roller drive motor, transporting the insulation board from the front end of the conveyor frame to the middle region of the conveyor frame.

[0010] Preferably, the passive conveying assembly includes passive rollers, which are equally spaced from the middle region to the rear end of the conveying frame. The passive rollers are freely rotatable to support and transition the insulation board.

[0011] Preferably, both the active roller and the passive roller are provided with anti-adhesion components to prevent the coating on the surface of the insulation board from adhering to the roller.

[0012] Preferably, the avoidance component includes a lifting cylinder, one end of which is rotatably mounted on the front end of the lifting frame, and the other end is rotatably connected to the front end of the pushing frame. The rear end of the pushing frame is hinged to the rear end of the lifting frame, so as to raise and lower the pushing frame by means of the lifting cylinder.

[0013] Preferably, the avoidance component further includes a first sensor and a second sensor. The first sensor is fixedly installed at the front end of the lifting frame, and the second sensor is fixedly installed at the rear end of the lifting frame. The position of the insulation board is detected by the first sensor and the second sensor, thereby controlling the lifting action of the lifting cylinder to ensure that the pushing frame avoids or pushes the insulation board at the appropriate time.

[0014] Preferably, the pushing assembly includes a pushing rod and a pushing cylinder. A guide rod is provided on the pushing frame. The guide rod is arranged parallel to the movement direction of the insulation board. The pushing rod is movably mounted on the guide rod. The pushing cylinder is fixedly mounted on the pushing frame. The moving end of the pushing cylinder is fixedly connected to the pushing rod to drive the pushing rod to push the insulation board.

[0015] Preferably, the insulation board lifting mechanism further includes a lifting height adjustment component, which includes a third sensor, a marking chute, and multiple sensor markings; the marking chute is fixedly mounted on the frame in a direction perpendicular to the ground; the multiple sensor markings are fixedly spaced along the length of the marking chute; the third sensor is fixedly mounted on the lifting frame and faces the marking chute; when the lifting frame moves up and down, the third sensor moves accordingly and can detect the position of the passing sensor markings, thereby determining the position of the lifting frame and precisely controlling its height based on the detected sensor markings to meet the transportation and stacking requirements of insulation boards of different sizes.

[0016] Preferably, the insulation board transport and palletizing device further includes an attitude correction component, which includes a fourth sensor and a fifth sensor. The fourth sensor and the fifth sensor are spaced apart on one side of the lifting frame to detect whether the insulation board entering the lifting frame is offset. If the insulation board is detected to be offset, the attitude correction component sends a signal to control the insulation board pushing mechanism to stop pushing.

[0017] The aforementioned insulation board transport and palletizing device includes a frame fixedly installed on the ground, an insulation board lifting mechanism, an insulation board conveying mechanism, and an insulation board pushing mechanism installed within the frame. The insulation board lifting mechanism controls the vertical lifting of the lifting frame through a drive component to adapt to different stacking height requirements. The insulation board conveying mechanism includes an active conveying component and a passive conveying component. The active conveying component transports the insulation board to the middle area of ​​the conveying frame, while the passive conveying component provides support and transition in the rear half of the conveying frame through a passive roller with a non-powered design. The insulation board pushing mechanism controls the lifting of the pushing frame through an avoidance component to prevent the pushing component from blocking the insulation board from entering the conveying frame. After the insulation board has completely stopped, the pushing component performs a pushing action, accurately pushing the insulation board into the curing frame. This not only achieves automated transport and palletizing of insulation boards but also, through the non-powered static support characteristics of the passive roller and the coordinated cooperation of the independent pushing mechanism, changes the traditional sliding friction between the insulation board and the conveyor belt to rolling friction between the insulation board and the roller, significantly reducing the risk of surface damage to the insulation board and improving product qualification rate and equipment operational reliability.

Detailed Implementation

[0030] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0031] Please refer to Figures 1 to 9 This utility model provides an insulation board transport and stacking device 10, including a frame 11 fixedly installed on the ground and an insulation board lifting mechanism 12, an insulation board conveying mechanism 13 and an insulation board pushing mechanism 14 disposed in the frame 11; the insulation board lifting mechanism 12 includes a lifting frame 121 and a drive assembly 122. The lifting frame 121 is disposed parallel to the ground inside the frame 11, and the drive assembly 122 is disposed on the frame 11 and fixedly connected to the lifting frame 121 to drive the lifting frame 121 to move up and down in a direction perpendicular to the ground; The insulation board conveying mechanism 13 is located below the lifting frame 121 and includes a conveying frame 131 fixedly installed below the lifting frame 121, an active conveying component 132 and a passive conveying component 133. The active conveying component 132 is located in the front half of the conveying frame 131 to convey the insulation board from the front end to the middle. The passive conveying component 133 is located in the rear half of the conveying frame 131 to support and transition the insulation board conveyed by the active conveying component 132. The insulation board pushing mechanism 14 is disposed between the lifting frame 121 and the conveyor frame 131. It includes a pushing frame 141, a pushing component 142, and a clearance component 143 disposed between the lifting frame 121 and the conveyor frame 131. The pushing component 142 is movably disposed on the pushing frame 141 to push the insulation board that is resting on the passive conveyor component 133 into the curing frame located on one side of the frame 11. During pushing, the insulation board is relatively stationary with the passive conveyor component 133 or rolls and rubs against it. The clearance component 143 is disposed on the lifting frame 121 and connected to the pushing frame 141. It can lift the pushing frame 141 before the insulation board enters the conveyor frame 131 so that the pushing component 142 can clear the insulation board. It can also lower the pushing frame 141 after the insulation board stops on the passive conveyor component 133 so that the pushing component 142 can push the insulation board.

[0032] Furthermore, the drive assembly 122 includes a first drive shaft 1221, a second drive shaft 1222, a top lifting sprocket 1223, a bottom lifting sprocket 1224, a lifting motor 1225, a first drive sprocket 1226, a first driven sprocket 1227, a second driven sprocket 1228, a first chain 1229, and a second chain 1231. The top of the frame 11 is provided with a first drive shaft 1221 and a second drive shaft 1222 parallel to the ground and located on both sides of the lifting frame 121. Top lifting sprockets 1223 are provided at both ends of the first drive shaft 1221 and the second drive shaft 1222. Bottom lifting sprockets 1224 are provided at the bottom of the frame 11 corresponding to the top lifting sprockets 1223 on each side. Each pair of top lifting sprockets 1223 and bottom lifting sprockets on the same side... Wheel 1224 is driven by first chain 1229; lifting frame 121 is fixedly connected to first chain 1229; lifting motor 1225 is also provided on the top of frame 11, and first drive sprocket 1226 is provided on lifting motor 1225; first driven sprocket 1227 is provided on first drive shaft 1221, and second driven sprocket 1228 is provided on second drive shaft 1222; first drive sprocket 1226, first driven sprocket 1227 and second driven sprocket 1228 are driven by second chain 1231, so that lifting motor 1225 drives first drive sprocket 1226 to rotate, drives first drive shaft 1221 and second drive shaft 1222 to rotate synchronously, and then drives first chain 1229 to drive lifting frame 121 to move up and down.

[0033] In this embodiment, the drive assembly 122 adopts a sprocket and chain drive to realize the vertical movement of the lifting frame 121. This method has a simple structure, high transmission reliability, and good wear resistance and corrosion resistance, enabling it to adapt to harsh working environments and thus extending the service life of the equipment. Furthermore, in this embodiment, both the sprockets (i.e., the top lifting sprocket 1223 and the bottom lifting sprocket 1224) and the chain are arranged in double rows to withstand greater torque and load, making it suitable for heavy-duty equipment. The first chain 1229 is rigidly fixed to the lifting frame 121 through a chain connector 1232, which has an anti-loosening structure to ensure the safety and reliability of the lifting process. The tooth ratio of the top lifting sprocket 1223 to the bottom lifting sprocket 1224 is 1:1 to ensure that the lifting frame 121 maintains horizontal movement. The lifting motor 1225 is preferably a servo motor with a braking function to achieve precise control of the lifting position.

[0034] In another embodiment, the drive assembly 122 is further provided with a tensioning mechanism located on top of the frame 11 for adjusting the tension of the second chain 1231. The tensioning mechanism includes a tensioning wheel and an adjusting bolt, which maintains optimal transmission tension of the second chain 1231 by adjusting the displacement of the bolt.

[0035] It should be noted that although this embodiment uses a chain drive, those skilled in the art will understand that the drive method can also be replaced by a synchronous belt drive or a gear and rack drive, etc., and these variations should all fall within the protection scope of this patent.

[0036] Furthermore, the active conveying assembly 132 includes an active roller 1321 rotatably mounted on the conveyor frame 131 and an active roller drive motor 1323. The active rollers 1321 are evenly spaced from the front end to the middle region of the conveyor frame 131. A roller driven sprocket 1322 is provided on the active roller 1321. The active roller drive motor 1323 is fixedly mounted on the conveyor frame 131. A roller drive sprocket 1324 is provided on the active roller drive motor 1323. The roller driven sprocket 1322 and the roller drive sprocket 1324 are connected by chain drive so that the active roller 1321 is driven to rotate by the active roller drive motor 1323, transporting the insulation board from the front end of the conveyor frame 131 to the middle region of the conveyor frame 131.

[0037] In this embodiment, the active conveying component 132 uses a sprocket and chain drive to synchronously drive multiple active rollers 1321, resulting in smooth transmission and a compact structure, effectively preventing slippage or deviation during the conveying of the insulation board. The tooth ratio between the roller drive sprocket 1324 and the roller driven sprocket 1322 is 1:1, ensuring that the linear speed of each active roller 1321 is consistent, thereby maintaining the uniform translation of the insulation board. The active roller drive motor 1323 is preferably a servo motor, supporting precise start / stop control and multi-speed adjustment to adapt to the conveying requirements of insulation boards of different specifications.

[0038] In another embodiment, the chain drive can be replaced with a synchronous belt drive to reduce operating noise and is suitable for production environments with high cleanliness requirements.

[0039] Furthermore, the passive conveying assembly 133 includes passive rollers 1331, which are equally spaced from the middle region to the rear end of the conveying frame 131. The passive rollers 1331 can rotate freely to support and transition the insulation board.

[0040] In this embodiment, the passive roller 1331 adopts a powerless free-rotation design, with both ends rotatably supported on the side plates of the conveyor frame 131 via ball bearings, ensuring that the insulation board can still slide smoothly to the rear station after detaching from the active conveyor assembly 132. The spacing of the passive rollers 1331 is set according to the minimum length of the insulation board (preferably 1 / 3 to 1 / 2 of the board length) to avoid deformation or jamming of the board due to excessive span.

[0041] In another embodiment, the passive roller 1331 can be replaced with an engineering plastic roller with self-lubricating function, which is suitable for high humidity or corrosive environments and extends the service life of the equipment; the connection area between the passive roller 1331 and the active roller 1321 can also be provided with a height adjustment mechanism (such as an eccentric bushing) to ensure a seamless transition of the conveying plane and avoid the insulation board from bumping or shifting at the junction.

[0042] Furthermore, both the active roller 1321 and the passive roller 1331 are provided with anti-adhesion components to prevent the coating on the surface of the insulation board from adhering to the rollers.

[0043] In this embodiment, the adhesive removal component consists of several layers of film wrapped on the active roller 1321 and the passive roller 1331, which are peeled off after the rollers have been running for a period of time, thereby removing the coating adhered to the film.

[0044] In another embodiment, the anti-adhesion component can be replaced with a removable rubber scraper that adheres to the roller surface by spring preload and automatically scrapes off the adhesive as the roller rotates; or a ceramic coating can be used to enhance wear resistance and corrosion resistance.

[0045] Furthermore, the avoidance assembly 143 includes a lifting cylinder 1431, one end of which is rotatably mounted on the front end of the lifting frame 121, and the other end is rotatably connected to the front end of the push frame 141. The rear end of the push frame 141 is hinged to the rear end of the lifting frame 121 so as to lift the push frame 141 by means of the lifting cylinder 1431.

[0046] In this embodiment, the piston rod end of the lifting cylinder 1431 is connected to the pusher frame 141 via a spherical bearing, and the cylinder body is hinged to the front mounting seat of the lifting frame 121 via a pin. The hinge point between the pusher frame 141 and the rear end of the lifting frame 121 adopts a hinge structure with a self-lubricating bushing to ensure that there is no jamming during the lifting process. The lifting cylinder 1431 is controlled by a pneumatic solenoid valve to lift the pusher frame 141 to a clearance position before the insulation plate enters the conveyor frame 131, and quickly reset after the insulation plate stops.

[0047] Furthermore, the avoidance component 143 also includes a first sensor 1432 and a second sensor 1433. The first sensor 1432 is fixedly installed at the front end of the lifting frame 121, and the second sensor 1433 is fixedly installed at the rear end of the lifting frame 121. The position of the insulation board is detected by the first sensor 1432 and the second sensor 1433, thereby controlling the lifting action of the lifting cylinder 1431 to ensure that the pushing frame 141 avoids or pushes the insulation board at an appropriate time.

[0048] In this embodiment, both the first sensor 1432 and the second sensor 1433 are photoelectric sensors, located 15cm from the front edge and 20cm from the rear edge of the lifting frame 121, respectively. The linkage logic between the sensor signals and the cylinder actions is implemented through a control component (Siemens S7-1200 PLC). When the first sensor 1432 detects that the front end of the insulation board has reached directly below it, it sends a signal to the control component, which immediately triggers the lifting cylinder 1431 to retract, causing the pushing frame 141 to descend and reset. When the second sensor 1433 detects that the rear end of the insulation board has disengaged from the passive conveying component 133, the control component delays for 0.8 seconds (the preset insulation board sliding buffer time) before initiating the action of the pushing cylinder 1422.

[0049] In another embodiment, the lifting cylinder 1431 can be replaced by an electric push rod or a hydraulic cylinder; the first sensor 1432 and the second sensor 1433 can also be ultrasonic sensors or magnetic encoders to adapt to dusty environments.

[0050] Furthermore, the pushing assembly 142 includes a pushing rod 1421 and a pushing cylinder 1422. A guide rod 1411 is provided on the pushing frame 141. The guide rod 1411 is arranged parallel to the movement direction of the insulation board. The pushing rod 1421 is movably mounted on the guide rod 1411. The pushing cylinder 1422 is fixedly mounted on the pushing frame 141. The moving end of the pushing cylinder 1422 is fixedly connected to the pushing rod 1421 to drive the pushing rod 1421 to push the insulation board.

[0051] In this embodiment, the guide rod 1411 is arranged perpendicular to the entrance of the curing frame, and its two ends are fixed to both sides of the pusher frame 141 via flange seats. A linear bearing is installed at the bottom of the pusher rod 1421, forming a sliding pair with the guide rod 1411. The cylinder body of the pusher cylinder 1422 is fixed to the pusher frame 141 by bolts, and the piston rod end is connected to the center of the pusher rod 1421 via a fisheye connector. When the insulation board stops in place, the pusher cylinder 1422 pushes the pusher rod 1421, smoothly pushing the insulation board into the curing frame. A buffer and a position sensor are installed at the end of the pusher to ensure no impact when stopping.

[0052] It is worth noting that the push assembly 142 also includes a position monitoring sensor to monitor whether the push rod resets after the insulation plate has been pushed.

[0053] In another embodiment, the guide rod 1411 can be replaced with a linear guide rail, and the push cylinder 1422 can be replaced with a servo electric cylinder to achieve multi-segment speed curve pushing, reduce the impact generated by pushing the insulation board, and avoid damage to the insulation board.

[0054] Furthermore, the insulation board lifting mechanism 12 also includes a lifting height adjustment component 124, which includes a third sensor 1241, a marking chute 1242, and multiple sensor marks 1243. The marking chute 1242 is fixedly mounted on the frame 11 in a direction perpendicular to the ground. The multiple sensor marks 1243 are fixedly mounted at intervals along the length of the marking chute 1242. The third sensor 1241 is fixedly mounted on the lifting frame 121 and faces the marking chute 1242. When the lifting frame 121 moves up and down, the third sensor 1241 moves accordingly and can detect the position of the sensor marks 1243 it passes through. Based on the detected sensor marks 1243, the position of the lifting frame 121 is determined and its height is precisely controlled to meet the transportation and stacking requirements of insulation boards of different sizes.

[0055] In this embodiment, the marking groove 1242 is welded to the side column of the frame 11, and its surface is provided with a scale. The sensor marking 1243 consists of several screws, the heads of which are installed in the marking groove 1242 and secured in the groove by nuts. The third sensor 1241 is a photoelectric sensor and is electrically connected to the control device. The position of each screw head corresponds to a different lifting height. When the third sensor 1241 detects a screw head, it indicates that the lifting frame 121 has reached the preset height. The third sensor 1241 sends a signal to the control component, and the control component immediately controls the lifting motor 1225 to brake. This not only makes the height adjustment more intuitive, but also ensures the stability of the sensor marking 1243 through the securing effect of the nuts, avoiding inaccurate positioning caused by loose markings. In addition, the scale further improves the accuracy of height adjustment, allowing the operator to more intuitively understand the current height of the lifting frame 121 and make corresponding adjustments accordingly.

[0056] In another embodiment, sensor marker 1243 may be replaced with a magnet, and third sensor 1241 may be replaced with a Hall sensor.

[0057] Furthermore, the insulation board transport and palletizing device 10 also includes an attitude correction component 15, which includes a fourth sensor 151 and a fifth sensor 152. The fourth sensor 151 and the fifth sensor 152 are spaced apart on one side of the lifting frame 121 to detect whether the insulation board entering the lifting frame 121 has shifted. If the insulation board is detected to have shifted, the attitude correction component 15 sends a signal to control the insulation board pushing mechanism 14 to stop pushing.

[0058] In this embodiment, the fourth sensor 151 and the fifth sensor 152 are installed 120cm apart on the left side of the lifting frame 121 along the conveying direction of the insulation board. When the insulation board is conveyed normally in the center, the fourth sensor 151 and the fifth sensor 152 are simultaneously blocked; if the offset of the insulation board is greater than 3cm (determined by the fourth sensor 151 continuously blocking while the fifth sensor 152 is not blocked), the attitude correction component 15 immediately sends an emergency stop signal to the control component, and the control component then cuts off the power to the push cylinder 1422 and triggers the audible and visual alarm.

[0059] In another embodiment, the attitude correction component 15 may be equipped with a mechanical correction mechanism, including a correction cylinder and a correction baffle. The correction cylinder is fixedly installed on the right side of the lifting frame 121, and the correction baffle is fixedly installed on the moving end of the correction cylinder. When a deviation is detected, the correction cylinder pushes the correction baffle to push the insulation plate back to its original position, thus avoiding direct shutdown.

[0060] In implementation of this utility model, the operator places the insulation board at the front end of the lifting frame 121 and then starts the device. The lifting motor 1225 drives the lifting frame 121 to descend to the receiving station via a sprocket and chain mechanism. When the first sensor 1432 detects that the front end of the insulation board has reached the predetermined position, the control component immediately triggers the lifting cylinder 1431 to retract, causing the pushing frame 141 to drive the pushing component 142 to descend to the pushing preparation position. The active roller drive motor 1323 starts synchronously, driving the active roller 1321 group to uniformly convey the insulation board to the passive conveying component 133 area via chain transmission. When the second sensor... When the device 1433 detects that the rear end of the insulation board has completely detached from the conveying area, the control component delays for 0.8 seconds (preset sliding buffer time) before activating the pushing cylinder 1422. This pushes the pushing rod 1421 along the guide rod 1411 to smoothly push the insulation board into the curing frame. During the pushing process, the third sensor 1241 continuously monitors the height of the lifting frame 121, achieving precise positioning through linkage with the sensor marker 1243 in the marking chute 1242. If the fourth sensor 151 and the fifth sensor 152 detect that the insulation board offset exceeds 3cm, the control component immediately interrupts the pushing action and triggers an audible and visual alarm. Throughout the process, the anti-adhesion component continuously prevents the insulation board coating from sticking to the roller, and the avoidance component 143 intelligently adjusts the height of the pushing frame 141 according to the insulation board position. This not only achieves fully automated operation of the insulation board from conveying and positioning to palletizing, significantly improving palletizing efficiency and quality, but also effectively avoids damage to the surface coating of the insulation board. At the same time, the multi-sensor collaborative control ensures the reliability and safety of the operation process.
