Description

Technical Field

[0001] The utility model relates to the technical field of packaging and printing, in particular to a glue-brushing device for packaging and printing. Background Art

[0002] Package printing is the printing process that uses various packaging materials as carriers, and prints decorative patterns, designs or texts on the packaging to make the product more attractive or more descriptive, thereby conveying information and increasing sales. It includes the printing of packaging cartons, packaging bottles, packaging cans, etc. Package printing occupies a large proportion in both the printing industry and the packaging industry, and is an indispensable part of the packaging project.

[0003] After searching, Chinese patent publication number CN217646739U discloses a glue brushing device with an anti-drip structure for packaging and printing equipment, which belongs to the field of packaging and printing equipment. The utility model discloses a glue brushing device with an anti-drip structure for packaging and printing equipment, including a processing table, an anti-drip part including an L-shaped frame arranged on one side of the connecting part and a cylinder part B arranged on one side of the L-shaped frame, and an anti-drip frame is fixedly installed on the other end of the cylinder part B. The utility model solves the problem that after the surface of the existing glue brush roller is stained with glue, excess glue is easily dripped from the glue brush roller, causing the surface of the paper box to be untidy. The operator turns on the motor to rotate the glue brush roller. At this time, the smearing roller stained with glue can smear glue on the glue brush roller, so that the surface of the glue brush roller is evenly stained with glue. The switch is used to make the cylinder part B push the anti-drip frame forward until the anti-drip frame is at the lower end of the glue brush roller, so that the excess glue can be collected, and the anti-drip effect is good.

[0004] However, in the above technical solution, glue is applied only by the application roller being dipped in glue in the glue box and contacting with the glue brush roller. The glue adhered to the surface of the application roller needs to be cleaned and scraped off when it is idle to prevent the glue from solidifying. The glue brush roller can be moved by the drive of the cylinder A, while the application roller always remains at the position of the lower opening of the glue box. At the same time, the surface of the glue brush roller will be adhered to glue only after it rolls with the application roller. At this time, the anti-drip frame is close to the application roller and affects its movement. When the glue brush roller moves down and contacts the printed matter, the glue adhered to the surface of the application roller is easy to gather and drip, and the anti-drip frame cannot move to its bottom to collect the glue. The dripping and splashing of glue will reduce the quality of the printed matter. Utility Model Content

At this time, the mounting plate 18 under the movable plate 17 will also move accordingly, and the scraper 19 on the mounting plate 18 is close to the glue brush roller 6 and the smear roller 7. As the glue brush roller 6 and the smear roller 7 rotate and contact with the scraper 19, the glue remaining on their surface is removed by the scraper 19 to prevent the glue from solidifying and adhering to its surface and affecting subsequent use.

[0032] In summary, when the present invention is in use, glue can be added from the opening at the top of the storage box 4 and sealed through the bottle cap. After the motor 8 is started, it will drive the glue brush roller 6 to rotate. The transmission assembly at one end of the glue brush roller 6 and the smear roller 7 will be driven by the rotation of the glue brush roller 6. The driving gear 10 connected to one end of the glue brush roller 6 will rotate and drive the driven gear 11 meshing with it. The driven gear 11 drives the smear roller 7 to rotate and evenly smear the glue in the storage box 4 on the smear roller 7 through the sponge block 12. The glue dripping from the opening of the storage box 4 on the smear roller 7 is transferred to the glue brush roller 6 through the rotation of the two, and then the glue brushing work is completed by the contact between the glue brush roller 6 and the printed matter. After the glue brushing is completed, the smear roller 7 and the glue brush roller 6 can be moved away from the storage box 4 through the first telescopic device 9 to facilitate cleaning of its surface; the glue brushing assembly is moved down and away from the storage box 4 At this time, the third telescopic device 16 is started. The third telescopic device 16 uses an air cylinder or a hydraulic cylinder. One end of the piston rod of the third telescopic device 16 drives the movable plate 17 to move. The movable plate 17 enters the bottom of the storage box 4 to block and seal its opening to prevent glue from overflowing. The anti-drip component enters the working state when the glue brushing component moves down and approaches the belt conveyor 3, close to the storage box 4, and the scraper 19 on the mounting plate 18 approaches the glue brushing roller 6 and the smear roller 7. As the glue brushing roller 6 and the smear roller 7 rotate and contact with the scraper 19, the scraper 19 removes the residual glue on its surface to prevent the glue from solidifying and adhering to its surface and affecting subsequent use; the extension of the piston rod of the second telescopic device 14 will drive the support plate 13 to move back and forth in the vertical direction, and the storage box 4 and the glue brushing assembly on the support plate 13 move close to and away from the belt conveyor 3, which is convenient for brushing glue on printed materials of different thicknesses.
