Description

Technical Field

[0001] This utility model relates to the field of card printing technology, specifically to a high-speed printing equipment conveying device. Background Technology

[0002] In continuous printing equipment, a conveyor mechanism is often required to continuously transport the printing media. However, when conventional conveyor mechanisms are used in high-speed card printing, problems such as card jitter and displacement can occur.

[0003] Chinese patent application CN216993621U discloses a single-pass UV printer, which includes a carrier platform, a conveyor belt, and a UV printing assembly. The conveyor belt and UV printing assembly are mounted on the carrier platform, which also has a pressure member for restricting material movement. The pressure member is located above the conveyor belt, and a material passage gap is formed between the pressure member and the conveyor belt for material to pass through. A printing channel is formed between the UV printing assembly and the conveyor belt. During printing, the material is placed on the conveyor belt, which transports the material to the UV printing assembly. As the material passes through the printing channel, the UV printing assembly prints on the surface of the material. During transportation, the pressure member restricts the material within the material passage gap, which keeps the material flat and prevents wrinkles and shifting, thereby improving subsequent printing accuracy. The disadvantage of this solution is that the pressure member is a fixed device, which cannot be used for cards of various sizes. Also, since a single card is relatively light, the guide belt lacks effective measures to ensure smooth card transport at high speeds (no less than 20 meters per minute). Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention aims to provide a high-speed printing equipment conveying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-speed printing equipment conveyor includes a perforated guide belt, a suction plate, a negative pressure fan, and a guide belt drive mechanism;

[0007] The perforated guide belt has a plurality of air holes evenly distributed on its surface, and the suction plate is disposed inside the perforated guide belt; the suction plate is hollow inside and has an exhaust hole on at least one side; a plurality of negative pressure fans are continuously arranged inside the suction plate along the conveying direction; a plurality of airflow grooves are evenly distributed on the top surface of the suction plate, the airflow grooves are recessed relative to the top surface of the suction plate, and a plurality of air holes are evenly distributed on each airflow groove; the guide belt drive mechanism is connected to the perforated guide belt and drives the perforated guide belt to rotate.

[0008] Furthermore, the airflow groove is recessed 3-5mm below the top surface of the suction plate.

[0009] Furthermore, the guide belt drive mechanism includes a driving roller, a driven roller, and a servo motor. The two ends of the perforated guide belt are respectively wound around the driving roller and the driven roller, and maintain a planar tension under the support of the driving roller and the driven roller. The driving roller is driven by the servo motor to rotate axially.

[0010] Furthermore, the high-speed printing equipment conveying device also includes a fixed side plate and a mounting side plate, and both ends of the driving roller and the driven roller are rotatably connected to the fixed side plate and the mounting side plate, respectively.

[0011] The beneficial effects of this utility model are as follows: Through the combined action of the perforated guide belt, the suction plate, and the negative pressure fan, the card can be tightly adsorbed onto the surface of the perforated guide belt during the transmission process, so that it can pass through the printing component smoothly and quickly. This solves the problems of card shaking and displacement during high-speed printing, improves the card printing yield, and further improves printing efficiency. Attached Figure Description

[0012] Figure 1 This is an exploded view of the conveying device in an embodiment of the present invention;

[0013] Figure 2 This is a schematic diagram of the suction plate in an embodiment of the present invention. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings. It should be noted that this embodiment is based on the present technical solution and provides detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to this embodiment.

[0015] This embodiment provides a high-speed printing equipment conveying device, such as... Figure 1-2 As shown, it includes a perforated guide belt 1, a suction plate 2, a negative pressure fan 3, and a guide belt drive mechanism.

[0016] The perforated guide belt 1 has a plurality of air holes evenly distributed on its surface, and the suction plate 2 is disposed inside the perforated guide belt 1; the suction plate 2 is hollow inside and has an open structure on both sides; a plurality of negative pressure fans 3 are continuously arranged inside the suction plate 2 along the conveying direction; a plurality of airflow grooves 9 are evenly distributed on the top surface of the suction plate 2, and the airflow grooves 9 are recessed relative to the top surface of the suction plate 2, and a plurality of air holes 8 are evenly distributed on each airflow groove 9; the guide belt drive mechanism is connected to the perforated guide belt 1 and drives the perforated guide belt 1 to rotate.

[0017] It should be noted that, under the action of the negative pressure fan 3, the airflow flows from the top surface of the suction plate into the airflow groove 9, passes through the air hole 8, and is discharged from both sides of the suction plate 2, forming a low-pressure area inside the airflow groove. The airflow groove 9 can balance the airflow through each air hole.

[0018] In this embodiment, the airflow groove 9 is recessed 3-5mm below the top surface of the suction plate 2.

[0019] In this embodiment, the guide belt drive mechanism includes an active roller 6, a driven roller 7, and a servo motor. The two ends of the perforated guide belt 1 are respectively wound around the active roller 6 and the driven roller 7, and maintain a planar tension under the support of the active roller 6 and the driven roller 7. The active roller 6 is driven by the servo motor to rotate axially.

[0020] Furthermore, in this embodiment, the high-speed printing equipment conveying device also includes a fixed side plate 4 and a mounting side plate 5, and both ends of the driving roller 6 and the driven roller 7 are rotatably connected to the fixed side plate 4 and the mounting side plate 5, respectively.

[0021] It should be noted that the active roller 6 is driven by a servo motor, while the driven roller has no power device. It moves together with the active roller and the perforated guide belt 1 to complete the stable operation of the guide belt.

[0022] When the document is conveyed using the aforementioned conveying device on the document printing equipment, the negative pressure fan 3 starts to draw in air. The air flows from top to bottom through the air hole 1 of the perforated guide belt 1 and the air hole 8 of the suction plate 2, and is then discharged through the exhaust hole on the side of the suction plate, creating negative pressure. This causes the document to adhere tightly to the surface of the perforated guide belt 1. Driven by the active roller 6 and cooperated with the driven roller 7, the perforated guide belt 1 maintains planar tension and drives the document to move at a constant speed at high speed, completing each printing process.

[0023] For those skilled in the art, various corresponding changes and modifications can be made based on the above technical solutions and concepts, and all such changes and modifications should be included within the protection scope of the claims of this utility model.
