Description

Technical Field

[0001] This utility model relates to the field of printing machine technology, specifically to an ink scraping device for a decorative edge banding printing machine. Background Technology

[0002] In the printing process of decorative edge banding strips and other products, the printing roller, as a core component, directly affects the printing quality due to the uniform distribution and effective control of the ink on its surface. The core advantage of the ink scraping device in a decorative edge banding printing machine is ensuring a uniform ink coating, saving ink consumption, and adapting to the printing needs of edge banding strips of different specifications. Through precise pressure and angle control of the doctor blade, excess ink on the printing plate surface can be scraped away, ensuring a consistent ink thickness transferred to the edge banding. This avoids problems such as ink accumulation, missed printing, and color differences, resulting in clearer and more aesthetically pleasing patterns and colors on the edge banding, thus meeting decorative requirements.

[0003] Traditional printing equipment may be equipped with ink scrapers or not. Another type of scraper may not meet the needs of actual users. It may not be able to tumble the ink to the center of the printing roller, or the seal between the scraper and the printing roller may not be tight enough, causing ink to flow through the gaps onto the printing press frame, contaminating the printing press surface and making it difficult for operators to clean the equipment.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example: An ink scraping device for a decorative edge banding printing machine, such as... Figure 1-5 As shown, it includes a rotating shaft 1, a printing roller 11, a fixing rod 2, a fixing block 3, and a fixing plate 4. The printing roller 11 is sleeved on the rotating shaft 1, and the fixing rod 2 is connected to the fixing block 3 through a connecting cylinder 21.

[0029] One side of the fixed block 3 is provided with a support plate 31 and a slide groove 301. A slide plate 32 is slidably connected in the slide groove 301. The slide plate 32 is provided with a groove 3201. A scraper 33 is installed in the groove 3201. One side of the fixed block 3 is provided with an adjustment plate 35 for adjusting the tilt angle of the scraper 33. The adjustment plate 35 is fixedly connected to the fixed block 3. Both sides of the support plate 31 are provided with a fixed plate 4 and a clamping plate 41. A scraper plate 42 is provided between the fixed plate 4 and the clamping plate 41. The scraper plate 42 is closely attached to the edge of both end faces of the printing roller 11 to prevent ink from flowing to both sides of the printing roller 11 and to guide the ink back to the middle position of the printing roller 11.

[0030] In this utility model, by setting the scraper plates 42 on both sides of the support plate 31, the ink scraper 33 is installed on the support plate 31, and then auxiliary scraper plates 42 are installed on both sides. The scraper plates 42 are made of silicone semi-rigid board, which is used to block the ink on both sides towards the middle position of the printing roller 11, and allow the ink to flow into the middle of the printing roller 11. The scraper plates 42 on both sides are in close contact with the printing roller 11 to prevent the ink from flowing out of the end face of the printing roller 11, so as to ensure that the ink will not drip onto the work table of the printing equipment, and at the same time, it is convenient for the operator to clean the printing machine table.

[0031] Furthermore, the slide plate 32 slides along the groove 301, the length direction of the groove 301 is perpendicular to the axial direction of the printing roller 11, and the slide plate 32 adjusts the contact position between the scraper 33 and the printing roller 11 by sliding.

[0032] Furthermore, the doctor blade 42 is made of silicone semi-rigid plate and has wear resistance and corrosion resistance. The doctor blade 42 is in close contact with the outer peripheral surface of the printing roller 11, and the contact part extends along the axial direction of the printing roller 11 to prevent ink from flowing out to the end face of the printing roller 11.

[0033] Furthermore, the included angle between the doctor blade 42 and the printing roller 11 is set to 100-150 degrees, and the angle of the doctor blade 42 is adjusted by adjusting the relative position of the fixing plate 4 and the clamping plate 41 to control the rate at which the ink is guided to the middle of the printing roller 11.

[0034] By setting the doctor blade 42 so that it forms an angle of 100-150 degrees with the printing roller 11, and the angle is adjustable, excess ink on both sides of the printing roller 11 can be stably guided back to the middle area, avoiding ink waste and reducing consumable costs. Moreover, the ink is concentrated in the middle of the printing roller 11, which can ensure that the ink distribution on the surface of the printing roller 11 is uniform, avoiding problems such as uneven printing texture and blurry patterns caused by too much or too little ink in some areas, thus improving the printing quality of decorative edge banding.

[0035] Furthermore, an adjusting bolt 34 for pushing the adjusting plate 35 is provided on the side of the fixed block 3 away from the slide groove 301. The angle and tightness of the scraper 33 are adjusted by turning the adjusting bolt 34 to change the amount of ink remaining on the printing roller 11. An adjusting cylinder 22 is sleeved on the fixed rod 2, and an adjusting handle 23 is provided on the adjusting cylinder 22. The adjusting handle 23 is rotatably connected to the adjusting cylinder 22. The tightness of the scraper plate 42 is adjusted by rotating the adjusting cylinder 22 and the adjusting handle 23.

[0036] The depth of the groove 3201 is matched with the thickness of the squeegee 33, which can accurately position and laterally constrain the squeegee, preventing it from shifting laterally or shaking due to force when scraping ink. At the same time, the connection strength between the squeegee and the slide plate 32 is further strengthened by the bolt fixing, which prevents the squeegee from loosening under long-term friction and ink impact from contacting the printing roller 11, ensuring the stability of the scraping force and position, thereby ensuring the uniformity of the printed texture.

[0037] Furthermore, the depth of the groove 3201 is adapted to the thickness of the scraper 33, and the scraper 33 is fixed in the groove 3201 by bolts.

[0038] By setting the groove 3201, the precise fit of the groove 3201 on the ink scraping device of the edge sealing strip printing machine can ensure that the verticality and flatness of the scraper 33 are consistent after installation, avoiding uneven scraping caused by misaligned installation (such as excessive ink residue or over-scraping in some areas). Combined with the sliding adjustment of the slide plate 32 and the angle / tightness adjustment of the adjusting bolt 34, it can flexibly adapt to inks of different viscosities, printing rollers 11 of different materials and printing products with different texture requirements, thus broadening the applicability of the device.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
