DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts are within the scope of the present application.

[0028] As shown in Figures 2-6 The present embodiment provides a printing device for digital printing, which comprises a fixing frame 1.

[0029] The conveying belt 2 in the present embodiment is arranged on the fixing frame 1 and used for transporting materials. The printing piece 4 is arranged on the upper side of the conveying belt 2. The conveying structure is arranged on the fixing frame 1 and used for transporting the printing piece 4. The first overturning piece 91 and the second overturning piece 92 are arranged on the two sides of the fixing frame 1. The control structure is arranged on the fixing frame 1 and used for moving the first overturning piece 91 and the second overturning piece 92 to be close to or away from the conveying belt 2.

[0030] The control structure in the present embodiment comprises a first control motor 6, a screw rod 61 rotatably arranged on the fixing frame 1, and an output shaft of the first control motor 6 fixedly connected with the screw rod 61. A first sliding rail 12 is fixedly arranged on the fixing frame 1, and the cross section of the first sliding rail 12 is in a “convex” shape structure, which is used for preventing the first mounting seat 711 and the second mounting seat 721 from sliding deviation. The first mounting seat 711 and the second mounting seat 721 are slidably arranged on the first sliding rail 12. First and second threads 611 and 612 are arranged on the two sides of the screw rod 61, and the rotation directions of the first and second threads 611 and 612 are opposite. Such a design ensures that the first mounting seat 711 and the second mounting seat 721 can simultaneously move towards or away from each other when the screw rod 61 rotates. The first mounting seat 711 is threadedly connected with the first thread 611, the second mounting seat 721 is threadedly connected with the second thread 612, the first overturning piece 91 is rotatably connected with the first mounting seat 711, and the second overturning piece 92 is rotatably connected with the second mounting seat 721. The first mounting seat 711 or the second mounting seat 721 is controlled to move by the screw rod 61. Since the rotation stroke of the screw rod 61 is much larger than the movement stroke of the first mounting seat 711 and the second mounting seat 721, the first mounting seat 711 and the second mounting seat 721 move more stably and accurately.

The second control motor 71 and the third control motor 72 in the embodiment are synchronous motors. The second control motor 71 and the third control motor 72 are used for controlling the 180° rotation of the mounting frame 8 in the embodiment, so that manual operation is not needed, and the automation degree is higher.

[0032] The transportation structure in the embodiment includes the fourth control motor 51, the mounting beam 3 is fixedly arranged on the fixed frame 1, the connecting rack 31 is fixedly arranged on the mounting beam 3, the transportation piece 5 is slidingly arranged on the mounting beam 3, the connecting gear 511 is rotatably arranged on the transportation piece 5, and the connecting gear 511 is engaged with the connecting rack 31. The fourth control motor 51 is used for controlling the movement of the transportation piece 5 in the embodiment, so that the printing piece 4 can move in the Y-axis direction, and the printing of the material to be printed is facilitated.

[0033] The second sliding rail 32 in the embodiment is fixedly arranged on the side wall of the mounting beam 3, the sliding groove 52 is arranged on the transportation piece 5, the second sliding rail 32 is slidingly connected with the sliding groove 52, and the cross section of the second sliding rail 32 is in a “convex” shape. The second sliding rail 32 is used for limiting the movement of the transportation piece 5 in the embodiment, so that the sliding deviation of the transportation piece 5 during transportation is prevented.

[0034] The telescopic piece 41 in the embodiment is arranged on the transportation piece 5, the fixed end of the telescopic piece 41 is fixedly connected with the transportation piece 5, and the telescopic end of the telescopic piece 41 is fixedly connected with the printing piece 4. The telescopic piece 41 in the embodiment is preferably a hydraulic cylinder or an air cylinder. The hydraulic cylinder and the air cylinder are prior arts, and will not be described herein. The telescopic piece 41 ensures the movement of the printing piece 4 along the Z-axis direction.

[0035] The mounting frame 8 in the embodiment is arranged on the conveying belt 2, the mounting frame 8 is abutted with the conveying belt 2, the limiting rail 11 is arranged on both sides of the fixed frame 1, and the mounting frame 8 is slidingly connected with the limiting rail 11. The limiting rail 11 is used for limiting the movement of the mounting frame 8 in the embodiment, so that the sliding deviation of the mounting frame 8 is prevented. The material to be printed can be placed in the mounting frame 8 for printing in the embodiment, and the turnover of the material is facilitated.

[0036] The working process of the embodiment is as follows: first, the material to be printed is placed in the mounting frame 8, the mounting frame 8 is transported to the printing part 4 through the conveying belt 2, the front surface of the material is printed through the fourth control motor 51 and the telescopic part 41, then the mounting frame 8 is transported to the first turnover part 91 and the second turnover part 92 through the conveying belt 2, the second control motor 71 and the third control motor 72 are started to turn over the mounting frame 8 by 180°, then the first turnover part 91 and the second turnover part 92 are moved away from the material through the first control motor 6, the conveying belt 2 is reversely started, and the material to be printed reenters the side close to the printing part 4 to be printed on the other surface.

[0037] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
