Description
Technical Field
[0001] The utility model relates to the technical field of digital printing equipment, in particular to a digital printing device. Background Art
[0002] Digital printing device is a device that uses digital technology to print, usually used to print various images, texts or designs on different types of surfaces. This device uses inkjet technology to print images directly on the target surface, which can achieve high resolution, fast and accurate printing effects. However, during the printing process, it is usually necessary to use a guide device to limit the direction and position of the printing target to ensure the accuracy and consistency of ink jetting, which is especially important when dealing with various materials and surfaces.
[0003] Traditional digital printing devices usually have an electric conveyor belt installed on the workbench of the digital printing device. In order to ensure the correct position of the printed object during the transmission of the electric conveyor belt, a support rod is usually installed on the workbench of the digital printing device, and then a guide plate is installed at one end of the support rod close to the center of the electric conveyor belt to limit the moving direction of the printed object or adjust its angle of entry into the inkjet area;
[0004] Traditional digital printing devices have the following problems: when the printing object is placed on the printing platform and moved to the conveyor belt, fixed support rods and guide plates are used, which limits the flexibility and freedom of the printing object during the transmission process. If the guide plate distance is not set properly, it may affect the accuracy of inkjet. Different types of printing objects may require different entry and exit angles to ensure printing accuracy and quality. The fixed-angle guide plate limits the adaptability of the equipment. For this reason, we propose a digital printing device. Utility Model Content

An electric transmission belt is installed inside the mounting groove by bolts. The input end of the electric transmission belt is electrically connected to the output end of the single-chip microcomputer to improve the continuity during printing.
[0012] Furthermore, the guiding mechanism also includes a limiting rod and a limiting hole, wherein the limiting holes are all opened inside the mounting seat, and the inner walls of the limiting holes are slidably connected to the limiting rods. The ends of the limiting rods located in the same mounting seat close to the center of the workbench are fixedly connected to the adjacent surface of a guide plate 1, ensuring that the guide plate 1 maintains stability and precise position during movement.
[0013] Furthermore, the guide mechanism also includes a knob, and the knob is fixedly connected to the outer end of the screw rod to drive the guide mechanism.
[0014] Furthermore, the angle adjustment mechanism includes a rotating groove and a connecting block. The rotating grooves are opened on the side of the guide plate 1 close to the center of the inkjet head. The inner wall of the rotating groove is rotatably connected to the connecting block through a pin shaft. The side of the connecting block close to the center of the inkjet head is fixedly connected to the guide plate 2, and the angle of the guide plate 2 can be adjusted.
[0015] Furthermore, the angle adjustment mechanism also includes positioning columns, sliding holes and positioning holes.

[0018] 1. By rotating the knob, the knob drives the screw to rotate, and the screw is connected to the mounting seat through a thread, so that the screw can move along the thread groove on the mounting seat. The rotation of the screw drives the limit rod to slide in the limit hole, thereby adjusting the spacing of the guide plate 1, ensuring that the guide plate 1 can move stably and remain in the required position to match the size of the printing target, thereby allowing the operator to accurately adjust the position of the guide plate 1 through simple manual operation. This accuracy realizes flexible adjustment according to the size of the actual printing object, allowing the digital printing device to handle printing objects of different sizes and shapes, thereby improving the flexibility of printing.
[0019] 2. By prying the guide plate 2, use the center of the pin shaft in the groove to rotate it. During the rotation, the chamfered surface at the bottom end of the positioning column contacts the chamfered surface at the edge of the positioning hole, so that the positioning column is separated from the vertically adjacent positioning hole. At this time, allow the guide plate 2 to rotate freely until the guide plate 2 rotates to the next positioning hole position. The spring will rebound, driving the positioning column to rebound and insert into the vertically adjacent positioning hole. In this way, the angle of the guide plate 2 is fixed in the new position. By adjusting the angle of the guide plate 2, the entry and exit angles of the inkjet head can be accurately adjusted to ensure that the inkjet head or inkjet device accurately enters and exits the inkjet area, thereby improving the overall operating efficiency and adaptability of the digital printing device.
