[0002] With the rapid development of optoelectronic technology, optical films, as key components, play an important role in various display and optoelectronic products. Currently, the printing technology of optical films is constantly advancing, but still faces challenges in terms of printing efficiency, accuracy, and quality.

[0003] Traditional optical film printing usually adopts manual or semi-automatic printing methods. Although this method can meet certain production requirements, it has limitations in terms of printing efficiency, accuracy, and consistency. Manual and semi-automatic printing methods are easily affected by human factors, resulting in unstable printing quality and low production efficiency, making it difficult to meet the needs of large-scale production.

[0041] The operator can realize the winding of the printed raw material 17 through the mutual cooperation between the second rotating roller 33, the third rotating roller 34 and the fourth rotating roller 35. The arrangement of the handle 36 and the universal wheels 37 facilitates the operator to push the trolley 27 to the corresponding position.

[0042] Refer to Figure 2 , Figure 4, a locking component 4 is arranged on the third fixing plate 32. The locking component 4 includes a locking block 41, a plugging block 42 and a locking spring 43. The locking block 41 is horizontally arranged and is in a rectangular block shape. The locking block 41 is fixedly connected to the third fixing plate 32. The plugging block 42 is in a rectangular block shape and is vertically arranged. The plugging block 42 slidably penetrates through the first fixing plate 13. An inclined surface is arranged on the end surface of the plugging block 42 close to the third fixing plate 32. A first sliding groove 131 is formed in the first fixing block 15, and the inner wall of the first sliding groove 131 is in sliding fit with the outer wall of the plugging block 42. A first plugging groove 132 is formed in the first fixing block 15, and the outer wall of the first plugging groove 132 is in sliding fit with the outer wall of the locking block 41.

[0043] The operator first pushes the cart 27 to the tail of the mounting bracket 12. When the locking block 41 matches the first plugging groove 132, the operator continues to push the cart 27. The plugging block 42 moves in the first sliding groove 131 under the action of the inclined surface and the locking block 41. At this time, the locking spring 43 is in a compressed state. When the locking block 41 moves to the innermost end of the first sliding groove 131, the plugging block 42 matches the second plugging groove 411. The plugging block 42 pops out under the action of the elastic force of the locking spring 43 and is inserted into the second plugging groove 411 to complete the locking of the cart 27.

The pull plate 52 is horizontally arranged and is fixedly connected to the pull rod 51. The operator pulls the pull plate 52. The pull plate 52 drives the locking block 41 to move in the first sliding groove 131 through the pull rod 51. At this time, the locking spring 43 is in a compressed state. When the plugging block 42 completely disengages from the second plugging groove 411, the operator can push the cart 27 away, that is, complete the unlocking of the cart 27.

[0045] The implementation principle of an optical film automatic printing machine in an embodiment of this application is as follows: The operator first pushes the cart 27 to the tail of the mounting bracket 12. When the locking block 41 matches the first insertion slot 132, the operator continues to push the cart 27 until the insertion block 42 is completely inserted into the second insertion slot 411, completing the locking of the cart 27. Then the operator starts the equipment. The motor 141 on the first fixed plate 13 drives the conveyor belt to operate, and the motor 161 drives the first rotating roller 16 to rotate, for unwinding the raw material 17. The raw material 17 is conveyed on the upper surface of the conveyor belt 14, and the paper pressing roller 61 effectively prevents the raw material 17 from wrinkling, improving the stability of the equipment. At this time, the first slider 21 slides on the first slide rail 2, the second slider 23 slides on the second slide rail 22, and the third slider 25 slides on the third slide rail 24. The movement of the third slider 25 drives the brush plate 26 at the bottom to move in all directions, realizing the printing of the raw material 17. The printed raw material 17 is dried by the air dryer 3. Then it is cut by the retractable blade 46, and then passes through the second rotating roller 33, the third rotating roller 34 and the fourth rotating roller 35 on the cart 27, realizing the winding of the printed raw material 17.

[0046] When the operator needs to collect the printed raw material 17, the operator only needs to pull the pull plate 52. The pull plate 52 drives the locking block 41 to move in the first sliding slot 131 through the pull rod 51. At this time, the locking spring 43 is in a compressed state. When the insertion block 42 completely disengages from the second insertion slot 411, the operator can push the cart 27 away, that is, complete the unlocking of the cart 27. Then the operator can collect and process the printed raw material 17.

[0047] The above are all the preferred embodiments of this application.
