Description

Technical Field

[0001] This invention relates to the field of melamine laminate technology, specifically to an automatic loading and unloading machine for melamine laminate. Background Technology

[0002] Melamine-faced panels, also known as melamine-faced environmentally friendly panels (MFC), are made by high-temperature pressing of a substrate (MDF, particleboard, moisture-resistant board, multi-layer solid wood plywood, etc.) and melamine-impregnated paper (base paper impregnated with special melamine adhesive). Chinese patent application number 202122784722.9 discloses a highly efficient, cyclically operating automatic loading and unloading machine for melamine-faced panels, including an operating table. Four adjusting columns are installed on the operating table, symmetrically arranged on both sides of the table surface. The adjusting columns on the same side of the operating table are connected by a first moving rail. A second moving rail is vertically mounted on each of the first moving rails, and a powered sliding plate is mounted on the surface of the second moving rail. A mounting plate is vertically connected to one side of the powered sliding plate. This high-efficiency, cyclically operating automatic melamine-faced panel loading and unloading machine is equipped with four adjusting columns. The moving horizontal rail is positioned between the adjusting columns, and the height of the moving horizontal rail on the operating platform can be stably adjusted by the hydraulic rods on the adjusting columns. This indirectly adjusts the height of the lifting plate, facilitating the loading and unloading of melamine-faced panels.

[0003] This technical solution only addresses the issue of manually moving melamine-faced panels onto a conveyor belt for transport. However, during loading and unloading, the solution requires first adsorbing the panels and then loading them, and unloading requires waiting for loading to complete, meaning loading and unloading cannot be done simultaneously. Furthermore, current melamine panels are often stacked in multiple pieces before and after lamination, requiring manual removal of panels from the stacking area during loading and unloading, and manual stacking after lamination, which is not conducive to rapid production. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic loading and unloading machine for melamine-faced panels to solve the technical problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automatic loading and unloading machine for melamine-faced panels includes a laminating machine, which is equipped with a conveying component and a support frame on the left side of the laminating machine.

Both ends of the push plate are movably sleeved on the limiting frame.

[0009] Preferably, the loading and unloading mechanism includes a motor frame, a drive motor, a first transmission belt, and a second transmission belt. The motor frame is fixedly installed on the top of a base plate located at the left end of the laminating machine. The drive motor is fixedly installed in the middle of the top of the motor frame. The two ends of the first transmission belt are respectively movably sleeved on the output shaft of the drive motor and the end of the threaded rod near the motor frame. The two ends of the second transmission belt are respectively movably sleeved on the ends of two threaded rods away from the motor frame.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] This embodiment describes an automatic loading and unloading machine for melamine-faced panels, such as... Figures 1 to 6 As shown, it includes a laminating machine 1, a conveying assembly 2, a support frame 3 on the left side of the laminating machine 1, and also includes a loading and unloading mechanism 4 and a pushing mechanism 5. The loading and unloading mechanism 4 includes a loading plate 402 and a unloading plate 403. The loading plate 402 is located at the left end of the conveying assembly 2 and inside the support frame 3, while the unloading plate 403 is located at the right end of the conveying assembly 2.

[0018] In this embodiment, as Figure 2 As shown, the loading and unloading mechanism 4 includes a base plate 401, a first support rod 404, and a second support rod 405. There are two base plates 401, which are respectively located below the loading plate 402 and the unloading plate 403. Two first support rods 404 are provided on each base plate 401, and their bottom ends are movably installed on one end of the base plate 401. Two sets of second support rods 405 are provided on each base plate 401, and their top ends are movably installed on one end of the loading plate 402 and the unloading plate 403, respectively. Each first support rod 404 is located between each set of second support rods 405, and the first support rod 404 and the second support rod 405 are movably connected in the middle by a pivot. By driving the bottom end of the second support rod 405 to move, the top end of the first support rod 404 moves simultaneously. When the distance between the top end of the first support rod 404 and the bottom end of the second support rod 405 increases, the upper plate 402 or the lower plate 403 rises, and vice versa.

[0019] In this embodiment, as Figure 2 and Figure 3 As shown, the loading and unloading mechanism 4 includes a lower limit groove 406, an upper limit groove 407, and a connecting arm 408. Two sets of lower limit grooves 406 are fixedly installed at the top of each base plate 401, located away from the end of the base plate 401 connected to the first support rod 404. Two sets of upper limit grooves 407 are fixedly installed at the bottom of both the upper plate 402 and the lower plate 403, respectively located away from the end of the second support rod 405 connected to the upper plate 402 and the lower plate 403. At one end, a sliding groove is provided in the middle of the side wall of each set of lower limit grooves 406 and upper limit grooves 407. The top end of the first support rod 404 is movably installed in the sliding groove of the upper limit groove 407. The connecting arm 408 is located in the middle of the interior of each set of lower limit grooves 406, and the end away from the first support rod 404 is movably installed in the sliding groove of the lower limit groove 406. The bottom end of the second support rod 405 is movably connected to the end of the connecting arm 408 away from the first support rod 404. The lower limit groove 406 connects to the connecting arm 408, and the connecting arm 408 connects to the bottom end of the second support rod 405, so that the bottom end of the second support rod 405 can move and be supported. The upper limit groove 407 connects to the top end of the first support rod 404, so that the top end of the first support rod 404, together with the top end of the second support rod 405, can support the upper plate 402 or the lower plate 403.

[0020] In this embodiment, as Figure 3 As shown, the loading and unloading mechanism 4 includes a push plate 409, a limiting frame 410, and a threaded rod 411. The push plate 409 is fixedly installed at one end of the connecting arm 408 near the first support rod 404. A threaded sleeve is provided in the middle of the push plate 409. The limiting frame 410 is fixedly installed in the middle of the top of the base plate 401. The threaded rod 411 is inserted into the threaded sleeve installed in the middle of the push plate 409 by thread. Both ends of the push plate 409 are movably sleeved on the limiting frame 410.

[0021] In this embodiment, as Figure 3As shown, the loading and unloading mechanism 4 includes a motor frame 412, a drive motor 413, a first transmission belt 414, and a second transmission belt 415. The motor frame 412 is fixedly installed on the top of a base plate 401 located at the left end of the laminating machine 1. The drive motor 413 is fixedly installed in the middle of the top of the motor frame 412. The two ends of the first transmission belt 414 are respectively movably sleeved on the output shaft of the drive motor 413 and the end of the threaded rod 411 near the motor frame 412. The two ends of the second transmission belt 415 are respectively movably sleeved on the ends of the two threaded rods 411 away from the motor frame 412. The threads on the two threaded rods 411 are in opposite directions. Specifically, the connection and mating parts between the two threaded rods 411 and the first transmission belt 414 and the second transmission belt 415 are not threaded. By starting the drive motor 413, a threaded rod 411 is driven to rotate via the first transmission belt 414, and two threaded rods 411 are driven to rotate simultaneously via the second transmission belt 415. When the threaded rod 411 under the upper plate 402 rotates, it drives the push plate 409 to move closer to the second transmission belt 415. The push plate 409 drives the bottom end of the second support rod 405 to move closer to the second transmission belt 415. At the same time, the top end of the first support rod 404 also moves closer to the second transmission belt 415 under the drive of the second support rod 405, causing the upper plate 402 to rise. Since the threads on the two threaded rods 411 are opposite in direction, the threaded rod 411 under the lower plate 403 drives the push plate 409 to move away from the second transmission belt 415, causing the lower plate 403 to fall.

[0022] In other aspects, this embodiment also provides a pushing mechanism 5 for feeding melamine boards stacked on the feeding plate 402 into the laminating machine 1, and pushing the laminated melamine boards to the top of the unloading plate 403 for stacking, such as... Figures 4 to 6 As shown, the pushing mechanism 5 includes a pushing frame 501, which is located at the top of the laminating machine 1 in the middle, with its left end located on the left side of the conveying component 2 and its right end located between the laminating machine 1 and the unloading plate 403.

[0023] In this embodiment, as Figures 1 to 6 As shown, the pushing mechanism 5 includes a pushing plate 502, a guide plate 503, and a guide block 504. There are two pushing plates 502, which are fixedly installed at the left and right bottom ends of the pushing frame 501, respectively. There are two guide plates 503, which are fixedly installed at the front and rear sides of the top of the laminating machine 1, respectively. Each guide plate 503 has two guide grooves on its side wall. The guide block 504 is set in each guide groove, and divides the guide groove into a straight groove and an inclined groove. The pusher frame 501 drives the pusher plate 502 to move simultaneously, and the pusher plate 502 pushes the board to be loaded and unloaded. The guide plate 503 and guide block 504 guide the connecting shaft 507.

[0024] In this embodiment, as Figure 5 and Figure 6 As shown, the feeding mechanism 5 includes a connecting frame 505, a partition plate 506, and a connecting shaft 507. The connecting frame 505 is located on the side of the guide plate 503 away from the middle of the top of the laminating machine 1, and its top end is fixedly connected to the guide block 504, and its bottom end is fixedly installed on the top of the laminating machine 1. The top end of the partition plate 506 is movably connected to the end of the guide block 504 near the unloading plate 403. There are two connecting shafts 507, and their two ends are movably installed in the guide grooves on the two guide plates 503, and are movably connected to the top of the feeding frame 501.

[0025] In this embodiment, as Figure 4 and Figure 5 As shown, the pushing mechanism 5 includes a pushing frame 508, a lifting groove 509, and an electric push rod 510. There are two pushing frames 508, which are respectively set on the side of the two connecting shafts 507 near the support frame 3. There are two sets of lifting grooves 509, which are respectively fixedly installed at both ends of the two pushing frames 508 and respectively movably sleeved on the two connecting shafts 507. One end of the electric push rod 510 is fixedly installed at the top of the support frame 3, and the output shaft of the electric push rod 510 is fixedly installed in the middle of one of the pushing frames 508 near the support frame 3. The electric actuator 510 drives the pusher 508 to move away from the support frame 3. The pusher 508 drives the lifting groove 509 to move, and the lifting groove 509 drives the connecting shaft 507 to move. This causes the pusher 501 to move synchronously with the two connecting shafts 507. The two ends of the connecting shaft 507 move in the guide groove on the guide plate 503. First, it moves along the straight groove and lifts the partition plate 506 when it contacts it. After the connecting shaft 507 leaves the partition plate 506, the partition plate 506 falls down. When the connecting shaft 507 moves from the end of the straight groove near the support frame 3 to the end near the unloading plate 403, the pusher 501 moves the distance of one plate with the connecting shaft 507.

[0026] The connecting shaft 507 moves along the partition plate 506 into the inclined groove. During this movement, the connecting shaft 507 gradually rises in the lifting groove 509. When it rises to the top of the inclined groove, it also rises to the top of the lifting groove 509. Since the connecting shaft 507 at the top of the inclined groove is no longer blocked by the guide block 504, it falls into the straight groove near the support frame 3, causing the connecting shaft 507 to reset. This causes the pusher frame 501 to reset along with the connecting shaft 507.

[0027] Working principle: In use, the melamine boards to be laminated are placed on the loading plate 402 using a forklift or other transfer device. At this time, the loading plate 402 is at its lowest point, and the unloading plate 403 is empty and at its highest point. After the melamine boards to be laminated are placed, the electric push rod 510 is activated. The electric push rod 510 pushes the push frame 508 to move away from the support frame 3. The push frame 508 drives the lifting groove 509 to move, and the lifting groove 509 drives the connecting shaft 507. The movement causes the pusher 501 to move synchronously with the two connecting shafts 507. The two ends of the connecting shafts 507 move in the guide grooves on the guide plate 503. First, it moves along the straight groove and lifts the partition plate 506 when it contacts the partition plate 506. After the connecting shaft 507 leaves the partition plate 506, the partition plate 506 falls down. When the connecting shaft 507 moves from the end of the straight groove near the support frame 3 to the end near the unloading plate 403, the pusher 501 moves the distance of one plate with the connecting shaft 507. The melamine board to be laminated on the feeding plate 402 is pushed to the conveying component 2 by the pusher plate 502 at the bottom left of the pusher frame 501. The conveying component 2 then transports the board to the laminating machine 1 for lamination. Meanwhile, the pusher plate 502 at the bottom right of the pusher frame 501 pushes the previous laminated melamine board to the top of the unloading plate 403. Subsequently, the pusher frame 508 is retracted via the electric push rod 510, and the connecting shaft 507 is retracted via the lifting groove 509. When the connecting shaft 507 moves towards the support frame 3, both ends of it are in the guide groove. Due to the action of the partition plate 506, it moves along the partition plate 506 into the inclined groove. At this time, the connecting shaft 507 gradually rises in the lifting groove 509 during the movement. When it rises to the top of the inclined groove, it also rises to the top of the lifting groove 509. Since the connecting shaft 507 located at the top of the inclined groove is no longer blocked by the guide block 504, it falls into the straight groove near the support frame 3, so that the connecting shaft 507 is reset, and the pusher frame 501 is reset along with the connecting shaft 507. During the upward movement of the pusher frame 501, the pusher plate 502 is driven to rise, so that the pusher plate 502 does not block the melamine board that has been laminated and transported through the conveyor component 2. When the melamine board is transported to the designated position, the conveyor component 2 stops. After the pusher plate 502 is reset, the pusher frame 508 is pushed again by the pusher frame 501 to drive the pusher plate 502 on the right side to push the melamine board that has been laminated and transported to the unloading plate 403 for stacking. During the rising and resetting process of the pusher frame 501, automatic loading and unloading is achieved by driving the upper plate 402 to rise and the lower plate 403 to fall simultaneously. During this process, the drive motor 413 is started, which then drives the threaded rod 411 to rotate via the first transmission belt 414, and the two threaded rods 411 rotate simultaneously via the second transmission belt 415. When the threaded rod 411 under the upper plate 402 rotates, it drives the push plate 409 to move closer to the second transmission belt 415. The push plate 409 then drives the bottom end of the second support rod 405 to move closer to the second transmission belt 415. At this time, the first support rod 404... The top also moves towards the second transmission belt 415 under the drive of the second support rod 405, causing the feeding plate 402 to rise. Since the threads on the two threaded rods 411 are in opposite directions, the threaded rod 411 located under the feeding plate 403 drives the push plate 409 to move away from the second transmission belt 415, causing the feeding plate 403 to fall. Therefore, the rising distance of the feeding plate 402 is the same as the falling distance of the feeding plate 403. By controlling the feeding plate 402 to rise by the thickness of one sheet each time, and by pushing the material through the push plate 502, the functions of automatically feeding the stacked melamine boards and automatically unloading and stacking the laminated boards are realized.
