Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to an adhesive scraping knife adjusting device on a coating machine. Background Art

[0002] Paper coating is a processing technology of applying a layer of coating on the base paper to endow the paper with good optical properties, printing properties or temperature properties. For papers with different thicknesses and properties, different coating methods are adopted, and common ones include gravure coating, reverse roll coating, knife roll coating, metering rod coating, slot film coating, impregnation, curtain coating, air knife coating, etc. Among them, the knife roll coating process is characterized in that the coating is first applied to the substrate, and then the excess part is scraped off by a scraping knife, and the gap left between the scraping knife and the substrate support roll is the coating thickness. This method can be used for high-viscosity coatings and high-density coatings, such as plastisols and rubber coatings.

[0015] Embodiment

[0016] As Figure 1 shown, a coating machine sizing blade adjusting device includes an adjustment roller 1, a sizing blade 3, an adjustment mechanism, and an end adjustment mechanism.

[0017] An installation groove is provided on the roller surface of the adjusting roller 1, and a placement block 2 is arranged in the installation groove. The outer end face and the inner end face of the placement block 2 are arranged in parallel, and the placement block 2 and the adjusting roller 1 are connected by a number of pressing screws 10. Blade clamping plates 4 are respectively arranged at the top end of the placement block 2 and the top end of the installation groove. The glue spreading scraper 3 is arranged between the two blade clamping plates 4, and the blade clamping plates 4 fix the glue spreading scraper 3. A gap suitable for fixing the glue spreading scraper 3 is left between the two blade clamping plates 4.

[0018] The adjusting mechanism includes a number of reference plates 5 and fixing plates 7. The reference plates 5 are arranged in parallel with the blade clamping plates 4. The reference plates 5 are fixedly connected to the placement block 2 through the fixing plates 7. A number of adjusting holes are provided on the reference plates 5, and adjusting screws 6 are arranged in the adjusting holes. The end of the adjusting screw 6 contacts the blade clamping plate 4. By rotating the adjusting screw 6, the distance that the adjusting screw 6 passes through the reference plate 5 can be changed, so as to apply different degrees of force to the blade clamping plate 4 and the glue spreading scraper 3. The glue spreading scraper 3 and the blade clamping plate 4 have low stiffness and undergo small-range deformation, thus realizing fine adjustment of the gap between the glue spreading scraper 3 and the substrate to be coated.

[0019] Two top fixing holes are provided at the top end of the fixing plate 7, and top fixing screws 8 connected to the reference plate 5 are arranged in the top fixing holes. A bottom fixing hole is provided at the bottom end of the fixing plate 7, and a bottom fixing screw 9 connected to the outer end face of the placement block 2 is arranged in the bottom fixing hole. The fixing plate 7 is used to connect the reference plate 5 and the placement block 2 to keep the reference plate 5 fixed.

[0020] Connecting rollers 11 are respectively arranged at both ends of the adjusting roller 1. The connecting rollers 11 pass through the support bearings 12 and are rotatably connected to the support bearings 12. The support bearings 12 are arranged on the support plate 21. When the connecting rollers 11 rotate in the support bearings 12, the whole adjusting roller 1 is driven to rotate, thereby greatly adjusting the position of the glue spreading scraper 3. When the glue spreading scraper 3 approaches the substrate to be coated, the whole enters the working state. When the glue spreading scraper 3 is far away from the substrate to be coated, the whole enters the maintenance state, which is convenient for replacing the glue spreading scraper 3, repair and maintenance work, etc.

[0021] The end adjusting mechanism is used to perform the specific rotation work of the connecting roller 11. The end adjusting mechanism includes a linkage ring 13, a linkage plate 16, an adjusting nail 14, and an adjusting seat. The linkage ring 13 is sleeved on the end of the connecting roller 11. A notch groove 15 is provided on the roller surface at the end of the connecting roller 11. The adjusting nail 14 passes through the linkage ring 13 and is inserted into the notch groove 15, and the adjusting nail 14 makes the linkage ring 13 and the connecting roller 11 rotate synchronously.

[0022] The top end of the linkage plate 16 is fixedly connected to the linkage ring 13. The bottom end of the linkage plate 16 is arranged inside the adjustment seat. The adjustment seat is arranged on the support plate 21. The adjustment seat includes a first vertical plate 19 and a second vertical plate 17 which are arranged oppositely. A pushing rod 20 is arranged on the first vertical plate 19. The pushing rod 20 is threadedly connected to the first vertical plate 19. An extrusion spring 18 is arranged on the side of the second vertical plate 17 facing the first vertical plate 19. The end of the linkage plate 16 is arranged between the pushing rod 20 and the extrusion spring 18. Under the elastic force of the extrusion spring 18, the linkage plate 16 has a tendency to approach the first vertical plate 19. When the pushing rod 20 is rotated, the distance between the bottom end of the linkage plate 16 and the first vertical plate 19 can be changed, thereby changing the rotation angles of the linkage ring 13 and the connecting roller 11.

[0023] Therefore, for the glue scraping knife adjusting device of a coating machine adopting the above structure in the present utility model, the entire adjusting roller 1 is adjusted at a large angle through the end adjusting mechanism to switch the working state or the maintenance state; the glue scraping knife 3 is finely adjusted in a small range through the adjusting mechanism arranged on the roller surface of the adjusting roller 1, so as to keep the gap between the glue scraping knife 3 and the substrate to be coated uniform.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present utility model, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present utility model.
