[0017] The present invention will be further described below with reference to the embodiments.

[0018] Please see Figure 1-4 This utility model provides a multi-color cardboard printing and dyeing material changing device, including a frame 1, support legs 2 and a printing and dyeing machine 3. The support legs 2 are fixedly installed at the four corners of the bottom of the frame 1. The printing and dyeing machine 3 is installed on the top of the frame 1. A controller 101 is fixedly installed at the front of the frame 1. A feeding mechanism 4 is provided on the left side of the printing and dyeing machine 3 and is located on the top of the frame 1. A drive motor 7 is fixedly installed at the front of the frame 1. A transmission roller 701 is fixedly connected to the rear end of the drive motor 7. A conveyor belt 702 is fitted on the outside of the transmission roller 701. The conveyor belt 702 is driven by the transmission roller 701 at the bottom of the printing and dyeing machine 3. A feeding mechanism 5 is provided on the left side of the frame 1. Cardboard 6 is placed on the upper part of the feeding mechanism 5.

[0019] Additionally, the controller 101 uses a PLC controller of model S7-1200. Its input terminals are electrically connected to photoelectric sensors (not shown in the attached figure) used to detect the position of the cardboard 6. The photoelectric sensors are set at the junction of the feeding mechanism 4 and the unloading mechanism 5 and at the inlet of the printing and dyeing machine 3. They are used to detect the position signal of the cardboard 6 and transmit it to the controller 101. The output terminals of the controller 101 are electrically connected to the control terminals of the drive motor 7, the first motor 406, the second motor 507 and the electric telescopic rod 402.

[0020] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the feeding mechanism 4 includes a mounting frame 401, which is fixedly mounted on the top of the frame 1. An electric telescopic rod 402 is fixedly mounted on the top of the mounting frame 401. A connecting frame 403 is fixedly connected to the bottom of the electric telescopic rod 402. A conveying roller 404 is rotatably mounted on the lower part of the connecting frame 403. A rubber anti-slip layer is provided on the surface of the conveying roller 404. A first motor 406 is fixedly connected to the front of the conveying roller 404. The first motor 406 is fixedly mounted on the connecting frame 403. A guide rod 405 is fixedly connected to the upper part of the connecting frame 403. The guide rod 405 is slidably connected through the mounting frame 401. The bottom horizontal height of the conveying roller 404 is brought to the lowest point by the electric telescopic rod 402 and is level with the upper horizontal height of the conveyor belt 702.

[0021] In use, the electric telescopic rod 402 operates, and the first motor 406 operates, causing the conveyor roller 404 to rotate on the connecting frame 403. The upper layer of the cardboard 6 is conveyed by the conveyor roller 404 to the upper part of the conveyor belt 702, and then conveyed by the conveyor belt 702 to the bottom of the printing and dyeing machine 3 for printing and dyeing work, thereby improving the printing and dyeing processing efficiency of the cardboard 6.

[0022] Specifically, when the cardboard 6 on the feeding mechanism 5 is conveyed to the area below the feeding mechanism 4, the photoelectric sensor triggers a signal, and the controller 101 first starts the electric telescopic rod 402 to extend, so that the conveyor roller 404 presses against the upper surface of the cardboard 6. Then, the first motor 406 is started to drive the conveyor roller 404 to rotate, and at the same time, the drive motor 7 is started to drive the conveyor belt 702 to run, so as to realize the conveying of the cardboard 6 from the feeding mechanism 5 to the conveyor belt 702. When the cardboard 6 is conveyed by the conveyor belt 702 to the inlet of the dyeing machine 3, the photoelectric sensor at the inlet triggers a signal, and the controller 101 starts the dyeing machine 3 to start the dyeing operation. After the dyeing is completed, the conveyor belt 702 continues to convey to the next process.

[0023] As can be seen from the above working process, by setting up the feeding mechanism 4 and cooperating with the unloading mechanism 5 to place and transport the cardboard 6, the cardboard 6 can be conveniently loaded and printed, thereby improving the convenience of loading the cardboard 6 and thus improving its processing efficiency.

[0024] Further as Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that the feeding mechanism 5 includes a placement platform 501, which is located below the feeding mechanism 4. Limiting blocks 509 are fixedly connected to the front and rear surfaces of the placement platform 501. The placement platform 501 slides on the frame 1 via the limiting blocks 509. The placement platform 501 is C-shaped and has an anti-slip layer on its upper surface. A first slide rail 502 is fixedly connected to the bottom of the placement platform 501. Two connecting slide blocks 503 are slidably mounted on the lower part of the first slide rail 502. Two connecting slides 503 are symmetrically arranged on the first slide rail 502. A telescopic frame 504 is hinged to the lower part of the connecting slides 503. A movable seat 505 is hinged to the bottom of the telescopic frame 504. A double-threaded rod 506 is threadedly connected to the movable seat 505. The double-threaded rod 506 is rotatably arranged on the frame 1. A second motor 507 is fixedly connected to the front end of the double-threaded rod 506. The second motor 507 is fixedly installed at the front of the frame 1. A second slide rail 508 is slidably arranged at the lower part of the movable seat 505. The second slide rail 508 is fixedly installed inside the frame 1.

[0025] In use, the second motor 507 operates, causing the bidirectional threaded rod 506 to rotate, which in turn drives the movable seat 505 to slide on the second slide rail 508. This causes the telescopic frame 504 to retract and support the connecting slide 503, allowing the connecting slide 503 to slide on the first slide rail 502. Consequently, the placement table 501 slides upward, pushing the cardboard 6 upward. This, in conjunction with the feeding mechanism 4, conveys the cardboard 6 for printing and dyeing, improving the practicality of the device. Furthermore, the placement of the cardboard 6 on the placement table 501 facilitates material replacement, further enhancing the device's usability.

[0026] Specifically, the frame 1 is provided with a T-shaped slide groove (not shown in the attached figure) at the position corresponding to the limit block 509. The limit block 509 is a T-shaped structure adapted to the T-shaped slide groove. It is made of wear-resistant cast iron and the surface is coated with polytetrafluoroethylene to reduce friction. The length of the T-shaped slide groove is 1.2 times the maximum moving distance of the placement platform 501 to ensure that the placement platform 501 does not derail when it is raised or lowered.

[0027] This solution has the following working process: When this device is in use, the stacked cardboard 6 is placed on the placement table 501 for printing and dyeing processing. At this time, the second motor 507 is operated, causing the bidirectional threaded rod 506 to rotate, thereby driving the movable seat 505 to slide on the second slide rail 508. This causes the telescopic frame 504 to retract and support the connecting slide 503, thereby causing the connecting slide 503 to slide on the first slide rail 502. This, in turn, causes the placement table 501 to slide upward, thereby pushing the cardboard 6 upward. At this time, the electric extension... When the retractor 402 operates, the first motor 406 causes the conveyor roller 404 to rotate on the connecting frame 403. The upper layer of the cardboard 6 is conveyed by the conveyor roller 404 to the upper part of the conveyor belt 702, and then conveyed to the bottom of the printing and dyeing machine 3 by the conveyor belt 702. The printing and dyeing machine 3 is then used for printing and dyeing, thereby improving the printing and dyeing efficiency of the cardboard 6. The cardboard 6 is placed on the placement table 501, which facilitates the material changing operation of the cardboard 6, thereby improving the practicality of the device.

[0028] In summary: By using the feeding mechanism 4 in conjunction with the dispensing mechanism 5 to place and transport the cardboard 6, the cardboard 6 can be conveniently loaded for printing and dyeing operations, thereby improving the ease of loading the cardboard 6 and thus increasing its processing efficiency; by using the dispensing mechanism 5, the cardboard 6 can be conveniently placed and processed on it, thus facilitating the replacement of the cardboard 6 and improving the practicality of the device.
