[0002] An inkjet printer is a product of a large printer series, mainly used for printing large-sized products, and is widely used in the printing operations of advertising curtains and large pictures.

[0003] In the existing patent application with the application number CN201921211376.1 and the name of "an inkjet printer with stable operation", an inkjet printer is disclosed, which includes a frame and a printing platform arranged on the frame. A cross beam is fixedly arranged on the upper side of the printing platform of the frame, and a printing carriage is slidably arranged along the length direction of the cross beam. An electromagnet group is fixedly arranged along the length direction of the cross beam, and a magnetic attraction member is arranged on one side of the printing carriage close to the electromagnet group. A plurality of magnetic attraction members are arranged in sequence along the length direction of the cross beam on the printing carriage. The inkjet printer completes printing and spraying through the printing carriage moving along the cross beam. However, the spraying carrier used by the inkjet printer has a large volume, and the existing inkjet printer needs to manually place the spraying carrier and take it out after spraying is completed, which greatly affects the efficiency of the spraying operation. Therefore, the structure of the existing inkjet printer needs to be further improved. Summary of the Utility Model

[0004] The purpose of the utility model is to make up for the above deficiencies and disclose to the society a feeding device with a simple and reasonable structure that can realize automatic feeding.

[0005] The technical solution of the utility model is realized as follows:

[0027] As Figures 1 to 4 shown, a loading device includes a storage frame 2 arranged beside the inkjet printer 1. Tracks 3 are respectively arranged on both sides of the inkjet printer 1. A moving frame 4 is arranged across the two tracks 3. A liftable loading transfer frame 5 is arranged on the moving frame 4. A plurality of suction cups 6 are arranged on the loading transfer frame 5. The suction cups 6 are connected to a negative pressure device (not shown in the figure) through a conduit. A pre-treatment platform 11 is arranged on the inkjet printer 1. A fixed baffle 71 is arranged on one side of the pre-treatment platform 11, and a moving push plate 72 driven by a driving device is arranged on the other side.

[0028] The inkjet carrier can be an inkjet board, a KT board, etc.

[0029] In this embodiment, the movable push plate 72 is driven by a cylinder disposed below the pre-finishing platform 11.

[0030] The suction cups 6 are evenly arranged on both sides of the loading transfer rack 5.

[0031] A spring 61 is arranged between the suction cup 6 and the loading transfer rack 5. The suction cup 6 is fixed to the bottom of the vertical rod, and the vertical rod can move up and down along the installation position. The spring 61 is provided to provide a buffering force when the loading transfer rack 5 moves down to adsorb the painting carrier. At the same time, the elastic force of the spring 61 gives a downward pressure to the suction cup 6, so that the suction cup 6 can adsorb the painting carrier more effectively.

[0032] The loading transfer rack 5 is fixed on the lifting rack 8, and both ends of the lifting rack 8 are in lifting cooperation with the moving rack 4.

[0033] Guide rails 41 are respectively arranged on both sides of the moving rack 4, and both ends of the lifting rack 8 are in sliding cooperation with the corresponding guide rails 41. The arrangement of the guide rails 41 on both sides can make the movement of the lifting rack 8 more stable and smooth.

[0034] The storage frame 2 includes a bottom frame 21, limit posts 22 are arranged at the four corners of the bottom frame 21, and limit grooves 22a are arranged inside the limit posts 22. The limit posts 22 at the four corners define the placement range of the painting carrier. The limit posts 22 with limit grooves 22a are used for limiting, so that the painting carrier is placed at the set position, preparing for subsequent loading.

[0035] The upper ends of the limit posts 22 are respectively provided with outwardly extending guiding parts 22b. The arrangement of the guiding parts 22b enables the painting carrier to have a certain tolerance during placement. By using the guiding function of the guiding parts 22b, the efficiency of placing the painting carrier into the storage frame 2 can be improved.

[0036] A cross beam 12 is arranged on the painting machine 1, and a print head 13 that can move along the cross beam 12 is arranged on the cross beam 12.

[0037] Working principle:

[0038] First, stack the painting carriers (painting boards, KT boards, etc.) to be painted in the storage frame 2. Start the equipment. The moving rack 4 moves along the track 3 to the upper part of the storage frame 2. The lifting rack 8 drives the loading transfer rack 5 to descend. After using the suction cups 6 on the loading transfer rack 5 to adsorb and fix the painting carrier under negative pressure, the lifting rack 8 ascends. After the moving rack 4 translates to the upper part of the pre-finishing platform 11, the lifting rack 8 descends, and the suction cups 6 cut off the air supply to put down the painting carrier.

[0039] During the falling process of the inkjet carrier, there may be a slight displacement. The air cylinder drives the moving push plate 72 to move towards the fixed baffle 71 (since the displacement of the inkjet carrier is caused by falling and the displacement is very small, the moving push plate 72 only needs to move a short distance here), until the inkjet carrier abuts against the fixed baffle 71, ensuring that the inkjet carrier is located at the set position, thereby ensuring the accuracy of the subsequent inkjet carrier pushing and the consistency of inkjetting for each inkjet carrier. As a supporting device for the inkjet printer, this feeding device can realize the automatic feeding of the inkjet carrier and effectively improve the inkjet efficiency.

[0040] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
