Description

Technical Field

[0001] This application relates to the technical field of printing equipment, and in particular to an anti-counterfeiting printing device. Background Technology

[0002] In the field of anti-counterfeiting printing, to enhance the anti-counterfeiting effect, papers with special structures, such as watermark paper and security thread paper, are often used as printing materials. These special papers are often characterized by their thinness and flexibility; however, in the actual printing process, these characteristics bring about many problems.

[0003] Currently, traditional anti-counterfeiting printing equipment has significant shortcomings when handling special types of paper. When special paper enters the printing press feed inlet, due to its light weight, it is prone to curling during the paper transport process due to its own flexibility, airflow, and uneven friction between the conveyor rollers. Once curling occurs, the paper will tangle and fold at the feed inlet, leading to paper jams. Utility Model Content

[0004] In order to reduce the occurrence of paper jams in anti-counterfeiting printing equipment, this application provides an anti-counterfeiting printing device.

[0005] The anti-counterfeiting printing equipment provided in this application adopts the following technical solution:

[0006] An anti-counterfeiting printing device includes an anti-counterfeiting printing machine body. The feeding end of the anti-counterfeiting printing machine body is provided with a feeding platform. A cavity is opened in the feeding platform. Multiple placement holes are opened in the upper part of the cavity. Multiple pulleys are provided in the upper part of the cavity. The placement holes correspond one-to-one with the pulleys. The upper sidewalls of the pulleys are placed outside the placement holes. A drive motor for driving the pulleys to rotate is provided at the upper end of the feeding platform. An air collecting hood is installed in the cavity. One end of the air collecting hood is fixedly connected to the upper inner wall of the cavity. A blower is installed at the other end of the air collecting hood. A support frame is erected above the feeding platform. A pressing component for pressing the product onto the pulleys is provided on the support frame.

[0007] By adopting the above technical solution, the paper can be placed on the feeding table and initially pressed onto the pulley by controlling the pressing component. Then, the paper is driven by the drive motor to move towards the entrance of the anti-counterfeiting printing machine. At the same time, the induced draft fan is turned on, so that the induced draft fan can adsorb the paper on the upper part of the feeding table. This can greatly reduce the occurrence of paper curling, thereby reducing the occurrence of paper jams in the anti-counterfeiting printing equipment.

[0008] Optionally, the pressing assembly includes a lifting plate, the lower end of which is rotatably connected to a pressing wheel, and a lifting component for driving the lifting plate to rise and fall is installed on the support frame.

[0009] By adopting the above technical solution, the paper can be pressed down by the pressure roller, thereby reducing the friction between the pressure plate and the paper.

[0010] Optionally, the lifting component is configured as a lifting cylinder, which is fixedly connected to the support frame, and the telescopic end of the lifting cylinder is fixedly connected to the lifting plate.

[0011] By adopting the above technical solution, the lifting cylinder can be controlled to extend and retract, thereby causing the lifting plate to move up and down.

[0012] Optionally, a filter mechanism is installed at the lower part of the air collecting hood to prevent impurities from falling into the induced draft fan.

[0013] By adopting the above technical solution, the filtration mechanism can prevent large-diameter impurities from falling into the induced draft fan.

[0014] Optionally, the filtration mechanism includes a filter plate located in the lower part of the air collecting hood, and the filtration mechanism further includes a support assembly for supporting the filter plate.

[0015] By adopting the above technical solution, the filter plate can be supported by the support components.

[0016] Optionally, the support assembly is located on the limiting blocks on both sides of the filter plate. The limiting blocks are fixedly connected to the inner wall of the air collecting hood. Each of the two limiting blocks has a sliding groove on the side that is close to each other. The filter plate is slidably connected in the sliding groove. A sliding hole is opened on the side wall of the air collecting hood opposite to the sliding groove. A support rod is fixedly connected to the filter plate and the support rod is placed outside the air collecting hood.

[0017] By adopting the above technical solution, the filter plate can be slid in the groove by the support rod, and then the filter plate can be slid out of the air collection hood through the sliding hole for cleaning and replacement.

[0018] Optionally, an inspection port is provided on the side wall of the feeding platform, and a baffle plate is rotatably connected to the inspection port.

[0019] By adopting the above technical solution, the filter plate can be replaced or treated through the inspection port.

[0020] Optionally, a sealing ring is provided at the contact point between the filter plate and the air collecting hood, and the sealing ring is fixedly connected to the outer wall of the filter plate.

[0021] By adopting the above technical solution, the airtightness between the filter plate and the air collector can be improved by using a sealing ring.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The blower can be turned on to draw the paper onto the upper part of the feeding table, which can greatly reduce the occurrence of paper curling and thus reduce the occurrence of paper jams in anti-counterfeiting printing equipment.

[0024] 2. The filtration mechanism can prevent large-diameter impurities from falling into the induced draft fan;

[0025] 3. The filter plate can be slid in the groove by the support rod, and then the filter plate can be slid out of the air collection hood through the sliding hole for cleaning and replacement. Attached Figure Description
