Description

Technical Field

[0001] The utility model relates to the technical field of packaging printing, in particular to an advertisement printing device used for packaging design. Background Art

[0002] Printing is the technology of batch copying the contents of original manuscripts such as text, pictures, photos, anti-counterfeiting, etc. through plate making, inking, pressurization and other processes, so that the ink is transferred to the surface of paper, textiles, plastics, leather, PVC, PC and other materials. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink.

[0003] When printing cartons and other packaging materials, there will be a lot of dust and paper scraps on the surface of the cartons during the production of raw materials. During the printing process, the dust and paper scraps on the surface of the cartons will adhere to the surface of the printing roller. The continuous accumulation of dust or paper scraps on the printing roller will affect the subsequent printing quality. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies of the prior art, the utility model provides an advertisement printing device for packaging design, which solves the problems raised by the above-mentioned background technology.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an advertising printing device for packaging design, comprising a printing roller for printing, and mounting frames symmetrically arranged on both sides of the printing roller, scraping strips for cleaning dust and paper scraps adhered to the printing roller and cleaning excess ink are respectively installed on the two sets of mounting frames, the mounting frame is provided with a mounting rod, and scraping strips are symmetrically distributed on both sides of the mounting rod, and the mounting rod is rotatably connected to the mounting frame through an adjusting device;

[0008] Two groups of scrapers for cleaning the scraper strips and cleaning devices for cleaning the scrapers are symmetrically arranged on the mounting frame to ensure that the dust, paper scraps and excess ink scraped from the printing roller by the scraper strips will not cause secondary pollution to the printing roller.

[0009] Preferably, the scraper strip is in contact with the surface of the printing roller, and the adjusting device includes a first mounting shaft, a first gear sleeved on the first mounting shaft, and a first rack meshing with the first gear. The mounting rod is rotatably connected to the mounting frame through the first mounting shaft, so that the positions of the two groups of scraper strips symmetrically distributed on both sides of the mounting rod are converted to ensure effective cleaning of the printing roller.

[0010] Preferably, the first rack slides in the mounting frame under the control of the first cylinder, and is used to adjust the first gear to drive the first mounting shaft to rotate, thereby controlling the rotation of the mounting rod.

[0011] Preferably, two sets of travel switches are respectively provided at the upper and lower ends of the first rack for controlling the rotation angle of the mounting rod so as to adjust the scraper strip to a suitable position.

[0012] Preferably, the mounting frame is provided with a movable frame that can slide left and right, which is used to install a scraper that can clean the scraper strip. The mounting frame is provided with a screw rod that rotates under the drive of a motor, which is used to control the movable frame to move left and right at a uniform speed on the mounting frame, thereby driving the scraper to move on the surface of the scraper strip to clean the scraper strip. A threaded rod that rotates under the control of a motor is installed in the movable frame to control the position of the scraper, thereby ensuring that the scraper fits the surface of the scraper strip and effectively cleans the brush strip.

[0013] Preferably, the cleaning device includes a fixed rod rotatably mounted with the mounting frame, a second mounting shaft for mounting the fixed rod, and a second gear, a second rack and a second cylinder for controlling the rotation of the fixed rod. A cleaning brush for cleaning the scraper is provided on the fixed rod. After the scraper moves to one side, the corresponding second cylinder drives the second rack to slide, and cooperates with the second gear to drive the fixed rod to rotate. The cleaning brush sweeps across the scraper surface to clean the scraper to avoid secondary contamination of the scraper strip by dust or paper scraps on the scraper.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides an advertising printing device for packaging design, which has the following beneficial effects:

[0016] The printing roller rotates counterclockwise, and the printing equipment feeds paper to the left for printing. During the printing process, dust or paper scraps on the surface of the raw material adhere to the printing roller, which are scraped off by the scraper on the left during the rotation. Excessive ink adhered to the surface of the printing roller during rotation is cleaned by the scraper on the right. When a group of scrapers completes the cleaning work, the direction of the mounting rod is changed through the adjustment device, and a new scraper is replaced for the next cleaning. The used scraper is cleaned by the scraper to avoid secondary contamination of the printing roller by dust, paper scraps or excess ink adhered to the scraper when it is used next time.

The first rack 503 slides in the mounting frame 2 under the control of the first cylinder 504, and is used to adjust the first gear 502 to drive the first mounting shaft 501 to rotate, thereby controlling the rotation of the mounting rod 3. Two groups of travel switches 505 are respectively provided at the upper and lower ends of the first rack 503 to control the rotation angle of the mounting rod 3 so as to adjust the scraper strip 4 to a suitable position. During the rotation of the printing roller 1, dust on the surface of the printing roller 1 is scraped off by the scraper strip 4 on the left, and excess ink is cleaned by the scraper strip 4 on the right. When one group of scraper strips 4 completes the cleaning work, the direction of the mounting rod 3 is changed through the adjusting device 5, and a new scraper strip 4 is replaced for the next cleaning.

[0026] In this embodiment, reference Figure 4 As shown, two groups of scrapers 6 for cleaning the scraper strip 4 and a cleaning device 10 for cleaning the scraper strip 6 are symmetrically arranged on the mounting frame 2 to ensure that the dust, paper scraps and excess ink scraped from the printing roller 1 by the scraper strip 4 will not cause secondary pollution to the printing roller 1. A movable frame 8 that can slide left and right is provided on the mounting frame 2 for installing the scraper strip 6 that can clean the scraper strip 4. A screw rod 9 that rotates under the drive of a motor is provided on the mounting frame 2 for controlling the movable frame 8 to move left and right at a uniform speed on the mounting frame 2, thereby driving the scraper strip 6 to move on the surface of the scraper strip 4 to clean the scraper strip 4. A threaded rod 7 that rotates under the control of a motor is installed in the movable frame 8 for controlling the position of the scraper strip 6 to ensure that the scraper strip 6 fits the surface of the scraper strip 4 and effectively cleans 1001 brushes.

When a group of scraper strips 4 completes the cleaning work, the direction of the mounting rod 3 is changed by the adjustment device 5, and a new scraper strip 4 is replaced for the next cleaning. The scraper plate 6 is pushed by the threaded rod 7 so that the scraper plate 6 fits the replaced scraper strip 4. The scraper plate 6 slides at a uniform speed on the mounting frame 2 driven by the screw rod 9, and the used scraper strip 4 is cleaned under the action of the scraper plate 6. After cleaning the scraper strip 4, the scraper 6 is moved to the left or right end of the mounting frame 2, and the corresponding second cylinder 1005 is started to drive the second rack 1004 to slide, and the second gear 1003 is cooperated to drive the fixing rod 1006 to rotate, and the cleaning brush 1001 sweeps the surface of the scraper 6 to clean the scraper 6, so as to avoid the dust or paper scraps on the scraper 6 causing secondary pollution to the scraper strip 4.
