Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a roller ink scraping mechanism of a printing machine. Background Art

[0002] A gravure printing press is a machine that uses a gravure plate for printing. The image and text part of the printing plate is concave, while the blank part is on the same plane as the outer circle of the printing plate cylinder. When the gravure printing press is printing, the entire surface of the printing plate cylinder is inked, and the ink on the blank part of the plate is scraped off with a scraper, leaving the ink on the image and text part, and printing is completed. In the existing device, the angle of the scraper aligned with the roller is suitable for the existing product style, and is fixedly installed inside the device. However, when changing to a different product for printing, the angle of the scraper is fixed and the ink may also be changed accordingly, which results in the angle of the scraper not being very suitable for new products, resulting in average printing effects. For this reason, a printing press roller scraping mechanism is proposed. Utility Model Content

Since the clamping part is fixed between the two rotating parts, the ink scraper can be initially rotated by a certain angle synchronously, and then the first nut can be loosened by a wrench. At this time, the clamping part sleeved in the first clearance hole is rotated by a certain angle to make the ink scraper fit the roller, and then the first nut is tightened. At this time, the angle adjustment is completed, avoiding printing errors and device failures caused by product changes. At the same time, the angle can be adjusted in time, which improves work efficiency and realizes the flexibility and reliability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0020] A printing press roller ink scraping mechanism provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0021] Example:

[0022] Combination Figure 1-4As shown, the utility model provides a printing press roller scraping mechanism, including a clamping member 1, a scraper 2 is arranged on one side of the clamping member 1, fixing bolts 3 are fixedly installed at both ends of the clamping member 1, a narrow space is opened in the middle of the scraper 2, when replacing the scraper 2, it is only necessary to insert the scraper 2 into the narrow space to achieve fixation, because the scraper 2 is a consumable, the design of the clamping member 1 makes it easy to replace, a first nut 5 is threadedly connected to the surface of the fixing bolt 3, a limiting ring is arranged at one end of the fixing bolt 3 to prevent the first nut 5 from falling off and causing device failure, and the thread length of the fixing bolt 3 is greater than the thickness of the first nut 5, so as to adjust the angle later and avoid jamming.

[0023] Among them, a rotating part 6 is sleeved in the middle of the fixing bolt 3, and a gasket 4 is sleeved at one end of the fixing bolt 3 close to the clamping part 1. One side of the gasket 4 fits with the rotating part 6. The gasket 4 protects the parts from being damaged by the clamping part 1 and the rotating part 6 due to excessive tightening of the first nut 5. At the same time, it can also increase the contact area to further fix the parts with the adjusted angles. A first clearance hole 7 is opened inside the rotating part 6, and the interior of the first clearance hole 7 is sleeved with the fixing bolt 3, that is, the clamping part 1 can rotate around the first clearance hole 7 under the action of the fixing bolt 3 to adjust the fit between the ink scraper 2 and the roller to avoid knife jumping, ink leakage and the like. A T-shaped slot 8 is opened in the middle of the rotating part 6, and a limiting hole 9 is opened inside the rotating part 6. A second clearance hole 10 is opened on the surface of the rotating part 6, and a flange bolt 11 is sleeved inside the second clearance hole 10. The rotating part 6 can rotate around the flange bolt 11. When the rotating part 6 rotates The second nut 12 is preferably a screw threaded connection, and the second nut 12 is preferably a screw threaded connection.

[0024] Furthermore, a circular plate 14 is clamped in the middle of the T-slot 8, and the middle of the flange bolt 11 is sleeved with the circular plate 14. The fixing points provided by the external device of the circular plate 14 can be adjusted by technicians according to the appearance of the device to adapt to the structure of the printing machine and achieve the purpose of fixing the device as a whole. An adjusting member 15 is sleeved inside the limiting hole 9, and the inner side of the adjusting member 15 is fixedly connected to the circular plate 14. A semicircular hole 16 is provided on the surface of the adjusting member 15. The inside of the rotating member 6 is slidably connected to the adjusting member 15. Through the action of the limiting hole 9 and the circular plate 14, the rotating member 6 can be stabilized to adjust the angle and avoid shaking that affects the printing effect.

[0025] The working principle and use process of the utility model are as follows: first, according to the optimal parameter requirements, the lever ring sleeve 13 is rotated, and the second nut 12 is driven to rotate at the same time, so that the second nut 12 is loosened on the surface of the flange bolt 11. At this time, the rotating part 6 is rotated to preliminarily adjust the angle. At this time, the lever ring sleeve 13 is rotated again to tighten the second nut 12. After this process, the first nut 5 is rotated to loosen the first nut 5 on the surface of the fixing bolt 3. At this time, the angle of the clamping part 1 is rotated and adjusted so that the scraper 2 clamped on one side of the clamping part 1 is fitted with the roller. At this time, the first nut 5 is rotated again to tighten it so that the first nut 5 is tightly fitted to one side of the rotating part 6 to complete the positioning.
