Description

Technical Field

[0001] The invention relates to the field of die-cutting devices, in particular to a self-adhesive sticker die-cutting device. Background Art

[0002] Die-cutting machine is also called die-cutting machine, cutting machine, CNC punching machine, which is mainly used for die-cutting (full cutting, half cutting), creasing and hot stamping operations, laminating, and automatic waste discharge of corresponding non-metallic materials, self-adhesive stickers, EVA, double-sided tape, electronics, mobile phone pads, etc. The die-cutting machine uses steel knives, hardware molds, steel wires (or templates carved from steel plates) to apply a certain amount of pressure through the stamping plate to cut printed products or cardboard into a certain shape.

[0003] Patent application number: CN202223158453.6 discloses a cutting mechanism and a die-cutting machine for producing self-adhesive stickers, including a workbench, a support arm, an electric telescopic rod, a die-cutting knife, and self-adhesive stickers. The workbench is connected to the support arm, and the electric telescopic rod is fixedly provided on the top inner side of the support arm. The end of the electric telescopic rod is connected to the cutting knife, and the cutting knife cuts the self-adhesive stickers; the self-adhesive stickers are cut by the cutting knife. When the cutting knife cuts the self-adhesive stickers, the self-adhesive stickers are easily stuck on the surface of the cutter, so that the front of the self-adhesive stickers will also be stuck with the self-adhesive stickers when cutting next time, which makes the quality of the self-adhesive stickers deteriorate.

[0004] The present invention is proposed in view of the deficiencies in the prior art. Summary of the Invention

[0005] The purpose of the present invention is to overcome the disadvantages of the prior art and provide a self-adhesive sticker die-cutting device.

[0006] The present invention can be achieved through the following technical solutions:

[0007] The present invention discloses a self-adhesive sticker die-cutting device, which includes a frame, the frame is provided with a conveyor belt, the conveyor belt is driven to rotate by a transmission motor, a top plate is fixed on the frame above the conveyor belt, and a plurality of cylinders are fixed on the top plate, the piston rod ends of the cylinders are fixed on the mounting plate, and a die-cutting knife is fixed on the bottom of the mounting plate. A cleaning device is symmetrically provided on both sides of the die-cutting knife, and the cleaning device includes a cleaning pipe, a rotating shaft is provided on one side of the cleaning pipe, and the rotating shaft is driven to rotate by a scraping motor. A cleaning roller is fixed on the rotating shaft, and a plurality of cleaning rods are evenly fixed on the cleaning roller, and a plurality of scraping strips are fixed on the cleaning pipe, and the scraping strips are arranged between two adjacent cleaning rods. The cleaning device also includes a limit plate fixed on the top plate, a positioning plate is fixed above the cleaning pipe, and a plurality of support rods are fixed on the positioning plate, the support rods pass through the limit plate and are slidably connected to the limit plate, and a plurality of supporting springs are fixed between the limit plate and the positioning plate. The sticker is transported forward by the conveyor belt, and the position to be cut on the sticker reaches just below the die-cutting knife. The cylinder is started, the piston rod on the cylinder extends, the mounting plate descends, and the die-cutting knife descends with the mounting plate, and the positioning plate is pushed by the supporting spring to enable the cleaning rod on the cleaning roller to stick to the surface of the die-cutting knife, and the sticker is cut by the die-cutting knife. After cutting, the die-cutting knife rises, and the cleaning roller is driven to rotate by the scraping motor. The cleaning rod rotates with the cleaning roller, and the cleaning rod contacts the surface of the die-cutting knife, so that the cleaning rod can scrape off the self-adhesive sticker on the die-cutting knife. After the self-adhesive sticker is scraped off, the cleaning roller continues to rotate, and the self-adhesive sticker on the die-cutting knife is scraped off by the scraping bar passing through the cleaning rods. This device can cut self-adhesive stickers and effectively clean the self-adhesive sticker on the die-cutting knife.

[0008] Preferably, a pressure plate is provided below the mounting plate, with a clearance opening extending through the pressure plate. A plurality of slide bars are also fixed to the pressure plate, extending through the mounting plate and slidably connected thereto. Limit blocks are also fixed to the tops of the slide bars, and a plurality of limit springs are also fixed between the pressure plate and the mounting plate. When the die cutter descends, the pressure plate descends with the mounting plate, and upon contact with the sticker, the pressure plate secures the sticker, thereby ensuring the smoothness of the sticker cut.

[0009] Preferably, positioning blocks are symmetrically fixed on both sides of the cleaning pipe. The positioning blocks can prevent the cleaning rods on the two cleaning rollers from contacting and colliding with each other.

[0010] Compared with the existing technology, the present invention has the following advantages:

[0011] The device can realize cutting of self-adhesive stickers and can effectively clean the self-adhesive stickers stuck on the die-cutting knife. BRIEF DESCRIPTION OF THE DRAWINGS
