Description

Technical Field

[0001] The utility model relates to the technical field of green printing ink adjustment, in particular to a green printing ink adjustment device. Background Art

[0002] Green printing refers to the use of environmentally friendly materials and processes, which produces less pollution during the printing process, saves resources and energy, is easy to recycle and reuse after the printed products are discarded, can be naturally degraded, and has little impact on the ecological environment. In the process of green printing, an ink mixing device is needed to mix the pollution-free inks of multiple required colors together to mix various required colors.

[0003] Publication number "CN209076497U" provides a green printing spot color ink mixing device, which controls the agitator through a motor to evenly and automatically mix and mix the offset printing spot color ink, which is fast, time-saving, labor-saving, and saves labor. Through the use of oleophobic coating, the offset printing ink hardly adheres to the inner wall of the ink mixing tank and the agitator, thereby reducing ink waste.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] The agitator in the ink mixing device can only stir and mix the ink at the bottom of the ink mixing tank, and cannot fully stir the ink on the upper side of the ink mixing tank. Therefore, in actual use, a long period of stirring is required to stir and mix the inks of various colors to a desired state, and the stirring and mixing range and efficiency are low. Some ink mixing devices in the prior art are mostly equipped with valves at the ink discharge end at the bottom so that the staff can control the on and off of the ink discharge through the valve. However, the installation of the valve makes it easy for a part of the ink in the ink mixing tank to enter the valve without being stirred and mixed. Later, when the valve is opened, the stirred and mixed ink will be discharged together with the ink in the valve. At this time, the ink in the valve that has not been stirred and mixed will affect the ink mixing uniformity of the discharged ink, and its practicality needs to be improved. Utility Model Content

[0032] Embodiment 2:

[0033] On the basis of the first embodiment, in this embodiment, during the process of stirring the ink inside the ink mixing tank 3 by the ink mixing component 4, the sealing seat 66 and the sealing baffle ring 65 prevent the ink from flowing into the ink discharge end 8 without being stirred. When the ink inside the ink mixing tank 3 is adjusted to the desired state, by controlling the electric hydraulic push rod 63 to contract, the electric hydraulic push rod 63 can drive the sealing seat 66 to move upward through the support plate 64, the low-speed motor 41 and the transmission rod 42. At this time, the ink in the ink mixing tank 3 will flow downward through the ink discharge end 8 into the ink receiving box 2, and the ink discharge is convenient.

[0034] The lifting assembly 6 includes a shield 61, an electric hydraulic push rod 63, a support plate 64 and a blocking seat 66. The upper end surface of the tank cover 5 is installed with a shield 61, and the shield 61 can shield the electric hydraulic push rod 63 and the low-speed motor 41. The electric hydraulic push rod 63 is installed on the upper side of the shield 61. The electric hydraulic push rod 63 is connected to the external control panel through a wire. When working, the electric hydraulic push rod 63 can drive the low-speed motor 41 to move up and down through the support plate 64. A support plate 64 is installed between the electric hydraulic push rod 63 and the low-speed motor 41, and the support plate 64 can support the low-speed motor 41. The bottom of the transmission rod 42 is connected to the blocking seat 66, and the blocking seat 66 can seal the ink discharge end 8 at the bottom of the ink adjustment tank 3. The sealing retaining ring 65 is made of highly tear-resistant silicone rubber, which makes the sealing seat 66 more airtight. An anti-slip ring is arranged on the inner side of the sealing retaining ring 65, and the anti-slip ring and the sealing retaining ring 65 are an integrated structure. The anti-slip ring prevents the sealing retaining ring 65 from slipping and loosening easily during use. Limiting rods 62 are symmetrically arranged on the left and right sides of the upper end surface of the support plate 64. The limiting rods 62 are connected to the support plate 64 by welding. The limiting rods 62 can be limited by the support plate 64 to prevent the support plate 64 from deflecting or shaking during the lifting and lowering process.

[0035] Working principle: Before green printing, the staff first removes the blocking cover 71 by lifting it, and then pours the prepared green, environmentally friendly and pollution-free ink of various required colors into the ink tank 3 through the ink fountain 7 (in this process, the ink level cannot exceed the highest level line to avoid the ink box 2 not being able to collect all the ink at one time due to the excessive amount of ink after ink mixing). After pouring, the blocking cover 71 is clamped on the upper end surface of the ink fountain 7 (refer to Figure 2), to prevent external dust from entering the ink mixing tank 3 through the ink fountain 7, and then start the low-speed motor 41, so that the low-speed motor 41 drives the transmission rod 42 to rotate at a low speed, and the transmission rod 42 drives the follower rod 46 and the stirring rod 44 to rotate synchronously, and then the stirring rod 44 drives the stirring blade 43 to rotate to stir and adjust the green, environmentally friendly and pollution-free ink of various required colors in the ink mixing tank 3. At the same time, the follower rod 46 drives the scraping bar 45 to rotate through the linkage rod 47, and the rotating scraping bar 45 scrapes off a part of the ink adhering to the annular side surface of the ink mixing tank 3, so that the scraped ink is stirred and adjusted by the stirring rod 44 and the stirring blade. Thereby, the ink mixing uniformity is ensured, and the compression spring 49 will squeeze the scraping strip 45 through the linkage rod 47, so that the scraping strip 45 and the ink mixing tank 3 are more closely fitted, thereby ensuring the scraping effect of the scraping strip 45; in the process of the ink mixing component 4 stirring and mixing the ink, the blocking seat 66 and the sealing baffle ring 65 also prevent the ink from flowing into the ink discharge end 8 without being stirred. When the ink is stirred and mixed to the desired state, the staff only needs to control the electric hydraulic push rod 63 to retract, so that the electric hydraulic push rod 63 drives the transmission rod 42 to move upward through the support plate 64 and the low-speed motor 41, and the transmission rod 42 will drive the blocking seat 66 to move upward together (reference Figure 4 ), at this time, the ink in the ink mixing tank 3 will flow downward through the ink discharge end 8 into the ink receiving box 2, and in this process, the rotating scraping bar 45 will continue to scrape off a part of the ink adhering to the inner annular side of the ink mixing tank 3, so that most of the residual ink can slide into the ink receiving box 2. When all the ink inside the ink mixing tank 3 is discharged, the staff can turn off the low-speed motor 41 and control the electric hydraulic push rod 63 to extend, so that the support plate 64 drives the blocking seat 66 to move downward through the low-speed motor 41 and the transmission rod 42 to block the ink discharge end 8 again. At this time, repeat the above operation to perform the next set of ink mixing operations.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
