[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] 1. When in use, during the movement of the sheet in the clamping mechanism, the flipping mechanism will pass through the notch in the middle of the middle platform, and the gear will be briefly meshed with the rack at the corresponding position, causing the gear to rotate. When the gear moves out of the range of the rack, at this time, it just rotates by degrees, and the fourth shaft is connected with the clamping mechanism, so that the sheet in the clamping mechanism can be synchronously rotated by degrees, and the sheet can be flipped so that the other side of the sheet faces up, so that it is convenient to print on the other side of the sheet;

[0024] 2. When in use, the sprocket is driven by the first motor to rotate clockwise, so that the chain rotates clockwise along a fixed track, and then the surrounding mechanism installed on the chain moves synchronously. When the surrounding mechanism moves, the flipping mechanism and the clamping mechanism installed on the surrounding mechanism move synchronously, achieving the effect of cyclic operation. With the cyclic operation of multiple surrounding mechanisms, flipping mechanisms and clamping mechanisms, the plates can be continuously loaded and unloaded, thereby improving work efficiency. In addition, the loading and unloading positions of the operator are always fixed, avoiding the operator from walking back and forth, reducing the operator's physical consumption and labor intensity;

[0025] 3. When in use, the bidirectional threaded rod is conveniently rotated by the first handle, so that the two sliders are moved closer to or farther from each other, and then the U-shaped frames are moved closer to or farther from each other, which is convenient for clamping plates of different widths.

[0042] like Figure 1-8As shown, the two printing mechanisms 8 both include a first base 801 and a second base 806. The bottom of the first base 801 is fixedly connected to the top of the base 1 near the rear side. The top of the first base 801 is symmetrically fixedly installed with a first slide rail 802, and a first slide plate 803 is slidably arranged between the outer surfaces of the two first slide rails 802. A second motor 804 is fixedly installed at the top of the first base 801 near the left side, and a first screw rod 805 is fixedly installed at the output end of the second motor 804. The outer surface thread of the first screw rod 805 penetrates the outer surface of the first slide plate 803 and extends to the other side.

[0043] like Figure 1-8 As shown, the bottom of the second base 806 is fixedly connected to the top of the middle platform 7, and the top of the second base 806 is symmetrically fixedly installed with second slide rails 807.

When the rack 809 moves, the bottom of its front side is supported by the second slide rails 807 to avoid weight imbalance on both sides of the rack 809 and improve the stability of the rack 809.

[0044] like Figure 1-8 As shown, a frame 809 is fixedly connected between the top of the first slide 803 and the second slide 808, a third slide rail 810 is symmetrically fixedly installed on the left surface of the frame 809 near the top, a moving frame 811 is slidably arranged between the outer surfaces of the two third slide rails 810, a third motor 812 is fixedly installed on the left surface of the frame 809 near the front side, a second screw rod 813 is fixedly installed on the output end of the third motor 812, the outer surface thread of the second screw rod 813 penetrates the outer surface of the moving frame 811 and extends to the other side, and the second screw rod 813 is driven to rotate by the third motor 812, which can drive the moving frame 811 to move left or right, thereby driving the printer head 814 to move synchronously, thereby controlling the Y-direction displacement of the printer head 814.

[0045] like Figure 1-8 As shown, a printer head 814 is arranged at the bottom of the movable frame 811. The printer head 814 is mainly composed of a nozzle, an ink jet control circuit, an ink storage unit, a heating plate and a sensor. Its working principle is to realize the printing of images or texts by controlling the ink jetting and movement of the nozzle. The device is an existing mature technology and will not be elaborated here.

[0046] In the utility model, when in use, the operator stands in the middle position of the front side of the device to operate, places the plate to be printed into the clamping mechanism 6 for clamping, rotates the bidirectional threaded rod 603 by the first handle 604, so that the two sliders 605 are close to or away from each other, which is convenient for clamping plates of different widths. After the plate clamping width is adjusted, the plate is inserted into the grooves of the two U-shaped frames 606, and the threaded column 607 is rotated by the second handle 608, so that the clamping plate 610 moves downward to apply pressure to the plate, thereby fixing the plate. Afterwards, the sprocket 203 is driven by the first motor 201 to rotate clockwise, so that the chain 204 rotates clockwise according to a fixed trajectory, thereby making the ring installed on the chain 204 The wrapping mechanism 4 moves synchronously. When the wrapping mechanism 4 moves, the wrapping wheel 405 in the wrapping mechanism 4 rotates along the track groove 31 on the annular rail 3, thereby ensuring the rationality and stability of the wrapping mechanism 4 during movement. At the same time, the flipping mechanism 5 and the clamping mechanism 6 installed on the wrapping mechanism 4 move synchronously to achieve the effect of circular operation. When the plate in the clamping mechanism 6 moves to the bottom of the printing mechanism 8 on the left, the printer head 814 at the corresponding position can be used to print one side of the plate. During the printing process, the first lead screw 805 is driven to rotate by the second motor 804, which can drive the first slide plate 803 to move left or right, and in turn, through the connection and cooperation between the frame 809 and the moving frame 811, the printer head 814 is driven to move synchronously. The second screw rod 813 is driven to rotate by the third motor 812, which can drive the movable frame 811 to move left or right, thereby driving the printer head 814 to move synchronously, and controlling the Y displacement of the printer head 814. With mutual cooperation, printing can be performed at any plane position of the corresponding plate. After one side of the plate is printed, the plate in the clamping mechanism 6 continues to move to the position of the right printing mechanism 8. During the movement, the flip mechanism 5 will pass through the notch 73 in the middle position of the middle table 7, and the gear 503 will briefly mesh with the rack 75 at the corresponding position during the movement. At the same time, the rectangular block 504 will break away from the guide groove 72 and come to the notch 73 position. At this time, the flipping mechanism 5 is no longer limited by the guide groove 72. When the gear 503 is meshed with the rack 75, the gear 503 will rotate. When the gear 503 moves out of the range of the rack 75, it just rotates 180 degrees. At the same time, the rectangular block 504 enters the guide groove 72 again. When the gear 503 rotates 180 degrees, the fourth rotating shaft 502 is connected with the clamping mechanism 6 to make the plate in the clamping mechanism 6 rotate 180 degrees synchronously, so that the plate can be flipped so that the other side of the plate faces up. When the plate moves to the bottom of the right printing mechanism 8, the other side of the plate can be printed by running the printer head 814 in the corresponding position, that is, the effect of double-sided printing of the plate is achieved, thereby improving work efficiency.When both sides of the sheet are printed, the sheet in the clamping mechanism 6 continues to move along the specified track. When passing through the right notch 73 in the middle table 7, the sheet can be flipped 180 degrees again through the cooperation of the flipping mechanism 5, so that the sheet position can be restored. After that, the sheet moves to the initial clamping position, and the operator can remove the sheet. At the same time, with the cooperation of multiple surrounding mechanisms 4, flipping mechanisms 5 and clamping mechanisms 6, the sheet can be continuously loaded and unloaded, which improves work efficiency. In addition, the position of the operator loading and unloading is always fixed, avoiding the operator to walk back and forth, reducing the operator's physical consumption and labor intensity.

[0047] The wiring diagram of the first motor 201, the second motor 804, the third motor 812 and the printer head 814 in the present invention is common knowledge in the art, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the first motor 201, the second motor 804, the third motor 812 and the printer head 814 are no longer explained in detail.
