Description

Technical Field

[0001] This utility model relates to the technical field of ink stirring devices, and in particular to an automatic ink stirring device for offset printing machines. Background Technology

[0002] Offset printing presses operate on the principle of planographic printing, which utilizes the immiscibility of oil and water. In offset printing presses, the image and non-image areas on the printing plate (usually an aluminum plate) are essentially on the same plane. During printing, to prevent problems such as viscosity changes, uneven composition, and oxidation of the ink during use, the ink is stirred during the printing process. This ensures the ink's fluidity and uniformity, improves print quality, reduces ink waste, and increases printing efficiency.

[0003] When machine operators discover a "color difference" in the product and need to stir the ink, they usually handle it manually. Although this method is simple and effective, the process is slow and the product loss is significant.

[0004] Therefore, how to design an automatic ink mixing device that can automatically mix ink is a technical problem that technicians need to solve. Utility Model Content

[0005] The purpose of this invention is to provide an automatic ink mixing device for offset printing machines to solve the problems mentioned in the background art.

[0011] Preferably, the outer wall of the adjusting pressure plate is in contact with the inner wall of the elastic connecting plate, and an elastic pressure plate is provided at one end of the adjusting pressure plate and one end of the sliding plate. A cleaning scraper is provided at one end of the elastic pressure plate, and a deformation groove is provided inside the elastic pressure plate.

[0012] Preferably, the other end of the skateboard is provided with an arc-shaped connecting plate, one end of the arc-shaped connecting plate is provided with a fixing plate, the fixing plate has a mirror-symmetrical structure at one end of the arc-shaped connecting plate, and the top of the skateboard is provided with a push handle.

[0013] Preferably, the mounting base is installed on the top of the offset printing machine body, the top of the mounting base is provided with a rotating frame, a rotating rod is rotatably sleeved inside the rotating frame, the sliding box is provided on the outer wall of the rotating rod, and a sliding block is provided inside the sliding box.

[0014] Preferably, the top of the sliding block is provided with an end fixing seat, the end fixing seat is provided with a sliding groove, the sliding groove slides and holds the ink stirring rod, and the ink stirring rod is provided with a fixing screw.

[0015] Preferably, the sliding block is provided with a positioning groove inside, the sliding box is provided with a positioning rod inside, the positioning rod is slidably sleeved inside the positioning groove, and the sliding box is provided with a stroke cylinder inside, one end of the stroke cylinder being connected to the side wall of the sliding block.

[0016] Preferably, the mounting base is provided with fixing bolts inside, and the mounting base is fixed to the top of the offset printing machine body by fixing bolts. A limit stop is provided on the top of the mounting base.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this example, by setting up an ink stirring mechanism, the reciprocating motion of the stroke cylinder is controlled to drive the ink stirring rod of the end fixed seat to stir the ink inside the ink fountain. This can replace manual ink stirring, reduce the labor intensity of operators, and provide convenient, fast, and continuous ink uniformity. Moreover, it can greatly reduce the scrap rate caused by product color difference.

[0019] In this example, by setting up a cleaning mechanism, not only can the ink adhering to the surface of the ink mixing rod be cleaned, but ink mixing rods of different sizes can also be cleaned. This setup allows for the cleaning mechanism to slide across the surface of the ink mixing rod after the ink mixing rod has stirred the ink, or when a different color ink is being changed, thereby cleaning the residual ink and preventing it from affecting the next stirring. On the other hand, when using ink mixing rods of different sizes, the cleaning mechanism can be slidably fitted onto the surface of ink mixing rods of different sizes, thus cleaning ink mixing rods of different sizes.

[0048] Example 1

[0049] In this embodiment, to address the problems of slow manual ink stirring speed and high product loss, the technical solution is as follows (refer to...). Figures 1 to 8 The stroke cylinder 206 is of the SWC series. The end fixing seat 207 is set on the top of the sliding block 205. The ink stirring rod 209 is slidably sleeved in the sliding groove 208 inside the end fixing seat 207. The ink stirring rod 209 is fixed to the sliding groove 208 by the fixing screw 210.

[0051] Example 2

[0052] In this embodiment, to address the problem of residual ink on the surface of the ink stirring rod 209 after stirring, which affects the quality of the next stirring, the technical solution of this embodiment is as follows (refer to...). Figures 1 to 8The elastic connecting plate 302 has an arc-shaped elastic curved surface structure. The sliding plate 301 is located at both ends of the elastic connecting plate 302 and has a mirror-symmetrical structure. The elastic connecting piece 304 is S-shaped, and the limiting slide frame 303 is U-shaped. The limiting slide frame 303 slides and is fitted onto the outer wall of the ink stirring rod 209. The elastic pressure plate 306 has an arc-shaped elastic curved surface structure, and the cleaning scraper 308 is made of rubber. After the ink stirring rod 209 stirs the ink, if there is a lot of residual ink on the surface of the ink stirring rod 209 or when changing to a different color ink, the cleaning scraper 308 is tightly attached to the surface of the ink stirring rod 209 under the action of the elastic pressure plate 306. Then, by pulling the push hand... The handle 311 drives the slide plate 301 and the cleaning scraper 308 to slide on the surface of the ink mixing rod 209, thereby cleaning the residual ink on the surface of the ink mixing rod 209 and preventing the residual ink from affecting the next mixing. On the other hand, when the ink mixing rod 209 is of different sizes, the slide plate 301 is slidably fitted onto the surface of the ink mixing rod 209, and the slide plate 301 is fixed to the surface of the ink mixing rod 209 by using the elastic connecting plate 302. Then, by adjusting the degree of deformation of the elastic connecting plate 302, the slide plate 301 can be slidably fitted onto the surface of the ink mixing rod 209 of different sizes, so that ink mixing rods 209 of different sizes can be cleaned.

[0053] It should be noted that the fixing plate 310 is an arc-shaped elastic curved surface structure. The two fixing plates 310 are mirror-symmetrical at one end of the arc-shaped connecting plate 309. By fixing the fixing plate 310 to the outside of the fixing screw 210, the cleaning mechanism 3 can be fixed to the outside of the ink stirring rod 209 when the ink stirring rod 209 is stirring ink, so as to avoid the cleaning mechanism 3 affecting the ink stirring process of the ink stirring rod 209.

[0054] Based on the above embodiments, when printing using the offset printing machine body 1, ink is added to the ink fountain 4. Then, by controlling the reciprocating motion of the stroke cylinder 206, the ink stirring rod 209 of the end fixing seat 207 is driven to reciprocate and stir the ink inside the ink fountain 4. This can replace manual ink stirring, reducing the labor intensity of operators, and is convenient, quick, and allows for continuous ink uniformity. Moreover, it can greatly reduce the scrap rate caused by product color difference. After the ink stirring rod 209 has stirred, by pulling the push handle 311, the slide plate 301 and the cleaning scraper 308 slide on the surface of the ink stirring rod 209. Because the cleaning scraper 308 is in close contact with the surface of the ink stirring rod 209 under the action of the elastic pressure plate 306, the residual ink on the surface of the ink stirring rod 209 can be cleaned during the sliding of the slide plate 301, avoiding the residual ink from affecting the next stirring.
