[0031] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0032] As shown in Figure 1 、 Figure 2 and Figure 3 A pusher plate device includes a first conveying unit 100, a lifting mechanism 200, a pusher plate mechanism 300 and a second conveying unit 400. The first conveying unit 100 is used to convey the packaging board stack 01 to the lifting mechanism 200. The lifting mechanism 200 is arranged in the lifting pit 00 on the side of the first conveying unit 100. The pusher plate mechanism 300 is arranged above the lifting mechanism 200. The pusher plate mechanism 300 is used to push the packaging board stacks on the top of the lifting mechanism 200 one by one from top to bottom onto the second conveying unit 400. The second conveying unit 400 is used to convey the single packaging board 02 onto the conveying roller 03 of the production line. Adopting this solution can realize mechanized pusher plate operation, reduce the labor intensity of workers, improve work efficiency, and facilitate the realization of assembly line operation.

[0033] As a preferred solution, as shown in Figure 2As shown, the first conveying unit 100 includes a first conveyor belt 101 and a first guide rail 102, and the first conveyor belt 101 is arranged between the two first guide rails 102 on both sides; a third conveying unit 210 is provided at the top of the lifting mechanism 200. The third conveying unit 210 includes a third conveyor belt 211 and a third guide rail 212. The third conveyor belt 211 is arranged between the two third guide rails 212 on both sides, and the third guide rail 212 can be docked with the first guide rail 102; the first conveyor belt 101 and the third conveyor belt 211 are respectively driven by a first motor 103 and a third motor 213, and are used to drive the pallet at the bottom of the packaged pallet stack 01 to move along the first guide rail 102 to the third guide rail 212. In order to facilitate the positioning of the packaged pallet stack placed on the first guide rail, a limiting plate 104 is provided on the side of the first guide rail 102, as Figure 3 shown. When placing the packaged pallet stack, the limiting plate is used to limit the packaged pallet stack, so that the rollers under the pallet at the bottom of the packaged pallet stack are correspondingly matched with the first guide rail. With the help of the rollers, the resistance suffered by the packaged pallet stack during transportation can be greatly reduced, and the packaged pallet stack can be quickly moved along the first guide rail to the third guide rail.

[0034] During the specific design, as Figure 1 , 2 shown, the lifting mechanism 200 includes a scissor lift 201 and a lifting platform 202. The scissor lift 201 is arranged in the lifting pit 00, the lifting platform 202 is arranged at the top of the scissor lift 201, and the third conveying unit 210 is arranged at the top of the lifting platform 202. After the packaged pallet stack is moved onto the lifting platform, it descends to the bottom with the scissor lift and then rises to the height of the pushing plate mechanism. During the pushing process, after each layer of packaged board is pushed away, the scissor lift will rise by the height of one layer of packaged board to facilitate pushing away the next layer of packaged board until all the packaged pallet stacks on the lifting platform are pushed away. This solution can adapt to packaged boards of different thicknesses and adjust the height of each lift of the scissor lift according to the thickness of the packaged board.

[0035] In a specific embodiment of the present invention, as Figure 2 , 3As shown, the push plate mechanism 300 includes a frame 301, a push plate frame 310 and a translation component 320. The frame 301 and the push plate frame 310 are both frame structures. The frame 301 is erected around the top of the lifting pit 00, and the frame 301 extends to the side above the lifting pit 00; the translation component 320 is arranged on the top of the frame 301, and the top of the push plate frame 310 is connected to the translation component 320. The translation component 320 is used to drive the push plate frame 310 to move horizontally, and the moving direction of the push plate frame 310 is perpendicular to the conveying direction of the third conveyor belt 211; a push plate assembly is provided at the bottom of the push plate frame 310, which is used to push the packaging plate stack 01 on the lifting platform 202 from top to bottom one by one onto the second conveying unit 400. Before the packaging board stack moves to the lifting platform, the push plate frame moves with the translation component to the side of the lifting platform away from the second conveying unit; after the packaging board stack moves to the lifting platform, the translation component drives the push plate frame to move toward the packaging board, and the push plate assembly can be used to push the upper packaging board to the second conveying unit.

[0036] When designing specifically, Figure 3 As shown, the translation component 320 includes a first translation motor 321, a first synchronous belt 323 and first slide rails 322 on both sides thereof. The two first slide rails 322 are symmetrically arranged on both sides of the top of the frame 301. The first synchronous belt 323 is driven by the first synchronous pulleys at both ends thereof. The push plate frame 310 is connected to the lower part of the first synchronous belt 323. The first synchronous pulleys at both ends are respectively arranged at the middle part of the first connecting shaft 324. The two ends of the first connecting shaft 324 are respectively arranged at the ends of the first slide rail 322. The first connecting shaft 324 is driven by the first translation motor 321. The ends of the two first connecting shafts 324 are connected by a chain, and the chain is connected to the first translation motor 321 by a sprocket. The first translation motor drives the first synchronous belt to run through chain transmission, thereby driving the push plate frame below to move.

[0037] In a specific embodiment of the present invention, Figure 2 , 3 As shown, the push plate assembly includes a second motor 311, a second synchronous belt 312 and a push plate 313 at the bottom thereof, the second synchronous belt 312 is driven by a second synchronous pulley, and the push plate is connected to the lower part of the second synchronous belt; the second synchronous pulleys at both ends of the second synchronous belt 312 are respectively arranged on the second connecting shaft 314, and the top two sides of the push plate frame 310 are provided with second slide rails 315, and the ends of the two second connecting shafts 314 are respectively arranged at the two ends of the second slide rails 315, and the second connecting shaft 314 is driven by the second motor 311. In view of the limited lower travel of the first synchronous belt, when the push plate frame moves to the end of the lower travel of the first synchronous belt, it cannot completely push the packaging board to the second conveying unit. At this time, the packaging board can be finally pushed to the second conveying unit with the help of the movement of the second synchronous belt.

[0038] During specific manufacturing, as Figure 2 , 4 shown, the push plate 313 is connected to the bottom of the push plate frame 310 through a connecting rod 316. An L-shaped edge 3130 bent downward is provided at the rear end of the push plate 313, and a guiding folded edge 3131 bent upward is provided at the front end of the push plate 313. Among them, a spring 317 is sleeved on the connecting rod 316. The upper end of the spring 317 is connected to the bottom of the push plate frame 310, and the lower end of the spring 317 is connected to the push plate 313. During specific operation, the packaging board can be conveniently guided into the push plate by means of the guiding folded edge at the front end, and then the edge of the packaging board is pushed by the L-shaped edge at the rear end to complete the push plate operation. Under the action of the spring, the push plate can be buffered to avoid bumping the packaging board.

[0039] To further optimize the above technical solution, as Figure 2 shown, two stacks of packaging boards can be placed side by side on the lifting table 202. The width of the push plate frame 310 matches the width of the two stacks of packaging boards. There are two push plates 313 and two second synchronous belts 312 respectively. The two push plates 313 and the two second synchronous belts 312 are arranged side by side, and the push plate 313 is connected to the lower part of the corresponding second synchronous belt 312. The two second synchronous belts 312 are respectively driven by two sets of second synchronous belt wheels. The two sets of second synchronous belt wheels are connected by two front and rear second connecting shafts 314. The ends of the two second connecting shafts 314 are connected by a chain. The chain is connected to the second motor 311 through a sprocket. The two second synchronous belts 312 and the push plate 313 are driven to move synchronously by the second motor 311. The two push plates can push two packaging boards onto the second conveying unit at one time. One directly enters the production line, and the other enters the waiting state, so as to realize the continuous conveying of the production line.

[0040] In a specific embodiment of the present invention, as Figure 1 , 3As shown in the figure, the second conveying unit 400 includes two groups of first conveying rollers 401 and second conveying rollers 402 arranged in parallel. The first conveying rollers 401 are arranged at the end of the conveying roller 03 of the production line and on the top of the bracket 403. The second conveying rollers 402 are arranged on the mounting frame 404. The mounting frame 404 is connected to the translation mechanism 410, and the translation mechanism 410 is used to push the second conveying rollers 402 above the first conveying rollers 401; the second conveying rollers 402 are arranged staggered with the first conveying rollers 401. Among them, the translation mechanism 410 and the mounting frame 404 are arranged on the bracket 403. The translation mechanism 410 includes a fourth motor 411, fourth synchronous belt wheels and fourth synchronous belts 412. There are two fourth synchronous belts 412, and there are two groups of fourth synchronous belt wheels. The two groups of fourth synchronous belt wheels are respectively connected to the fourth connecting shaft 413, and the fourth connecting shaft 413 is driven by the fourth motor 411; the mounting frame 404 is connected to the lower part of the fourth synchronous belt 412. The specific working process is as follows:

[0041] When two push plates push two packaging boards side by side to the roller path where the front first conveying rollers and second conveying rollers are located, the roller path of the first conveying rollers is connected to the production line and can directly convey the packaging boards away, and the other packaging board is pushed to the waiting roller path where the second conveying rollers are located. After the packaging board on the first conveying rollers is conveyed away, the fourth motor on the waiting roller path starts, and the fourth synchronous belt wheels can push the packaging board on the second conveying rollers to the roller path of the first conveying rollers, and then enter the production line. Subsequently, the lifting table rises to start the next push plate operation.

[0042] To sum up, the utility model has the advantages of simple and compact structure and high working efficiency. By using mechanized push plate operation to replace manual separation of packaging boards, it liberates the labor force. The staff only needs to operate the equipment to complete the push plate operation, greatly reducing the labor intensity of the staff, facilitating the realization of assembly line operation, and is especially suitable for batch continuous production.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
