Description

Technical Field

[0001] The utility model relates to the technical field of offset printing machines, in particular to an automatic adjusting device for dampening water of offset printing. Background Art

[0002] An offset printing press is a mechanical device that uses an indirect printing method for printing. Its working principle is to first apply ink to the rubber cylinder, then transfer the ink to the printing plate through the contact between the rubber cylinder and the plate cylinder, and finally print the ink onto the paper through the contact between the plate cylinder and the paper. This printing method enables the offset printing press to print colorful, clear patterns, and distinct layers of printed products. Offset dampening water can also help replenish the hydrophilic layer that may be damaged during the printing process. The hydrophilic layer is a thin film on the surface of the printing plate, which plays a key role in the adhesion and uniform distribution of ink. As printing progresses, the hydrophilic layer may gradually wear out. At this time, dampening water can replenish this layer to ensure the smooth progress of the printing process. However, the offset dampening water of traditional offset printing presses is inconvenient to adjust, the flow rate cannot be automatically adjusted, and it is not convenient to collect the residual water inside the pipe after use, resulting in waste of resources and may also cause pollution to the equipment. There are certain disadvantages.

[0003] In summary, the utility model solves the existing problems by designing an offset printing dampening water automatic regulating device. Utility Model Content

[0025] For examples, see Figure 1-5 , the utility model provides a technical solution:

[0026] An automatic regulating device for dampening water for offset printing comprises a water storage barrel 1, a liquid level gauge 2 is installed on one side wall of the inner part of the water storage barrel 1, a water inlet 3 is provided at one end of the top of the water storage barrel 1, a control device 4 is installed on one side surface of the outer part of the water storage barrel 1, a connecting pipe 5 is installed at the bottom edge of one side surface of the outer part of the water storage barrel 1 and on the same side of the control device 4, a slide groove 501 is symmetrically provided on both side walls of the inner part of the connecting pipe 5, a return spring 6 is installed on one side wall of the inner part of the slide groove 501, a movable plate 7 is installed together at one end of the return spring 6, a fixed plate 8 is installed on the top of the movable plate 7, a connecting rod 9 is installed on one side surface of the outer part of the movable plate 7, a valve ball 10 is installed at one end of the connecting rod 9 away from the movable plate 7, a rotating shaft 11 is installed on the inner top of the connecting pipe 5, and an elliptical block 12 is installed at one end of the bottom of the rotating shaft 11;

[0027] A servo motor 13 is installed on the top of the connecting pipe 5, a first pipe 14 is installed on the side of the outside of the connecting pipe 5 away from the water storage barrel 1, a flow meter 15 is installed inside the first pipe 14, a second pipe 16 is installed at one end of the first pipe 14, a fixing ring 17 is installed on the outer ring surface of the bottom end of the second pipe 16, a square pipe 18 is installed on the outer end of the fixing ring 17, a slider 19 is installed on the outside of the square tube 18, a cross plate 20 is installed on one side of the outside of the slider 19, a first support plate 21 is installed on one end of the outside of the cross plate 20, a turntable 22 is installed on one side of the outside of the first support plate 21, a second support plate 23 is installed on the end of the outside of the cross plate 20 away from the first support plate 21, a bidirectional threaded rod 24 is installed between the outer side surfaces of the first support plate 21 and the second support plate 23, arc-shaped clamping blocks 25 are symmetrically installed at both ends of the outer ring surface of the bidirectional threaded rod 24, and a collecting bottle 26 is installed between the inner side walls of the arc-shaped clamping blocks 25.

[0028] Specifically, refer to Figure 3 One end of the top of the rotating shaft 11 passes through the top of the connecting pipe 5 and is connected to the output shaft of the servo motor 13, and the outer annular surface of the rotating shaft 11 is rotatably connected to the inside of the connecting pipe 5, thereby ensuring that the rotating shaft 11 is driven to rotate by the servo motor 13, thereby driving the elliptical block 12 to rotate. When the elliptical block 12 rotates, it will squeeze the fixed plate 8, and the fixed plate 8 drives the movable plate 7 to move and stretch the two reset springs 6, thereby driving the valve ball 10 away from the interface of the first pipe 14, thereby realizing the adjustment of the water flow rate inside the first pipe 14.

[0029] Furthermore, sliding blocks are provided at both ends of the movable plate 7 and are slidably connected to the inner walls of the slide groove 501, and when the reset spring 6 is in the initial state, the valve ball 10 is close to the first pipe 14 and the valve is in a closed state, thereby ensuring that the movable plate 7 slides inside the two slide grooves 501 to drive the valve ball 10 away from or close to the first pipe 14 to control the flow rate.

[0030] Furthermore, the outer side surface of the square tube 18 is slidably connected to the inside of the slider 19, and a limit block is provided at one end of the square tube 18 to prevent the slider 19 from detaching from the outside of the square tube 18, thereby ensuring that the valve ball 10 is closed after use. However, water will remain on the inner walls of the first pipe 14 and the second pipe 16. By pushing the slider 19 to slide on the outside of the square tube 18, the collection bottle 26 is moved to the bottom of the second pipe 16 to collect the water inside the first pipe 14 and the second pipe 16, thereby avoiding waste and protecting the equipment from contamination.

[0031] Furthermore, anti-skid pads are provided on the inner side walls of the arc-shaped clamping blocks 25, and when the two arc-shaped clamping blocks 25 move on the outer ring surface of the bidirectional threaded rod 24, one end of the arc-shaped clamping block 25 is slidably connected to the outer side surface of the cross plate 20, thereby ensuring that the friction between the arc-shaped clamping block 25 and the collecting bottle 26 is increased by providing the anti-skid pads, and the stability of the arc-shaped clamping block 25 moving on the outer ring surface of the bidirectional threaded rod 24 is increased by the sliding connection between the two arc-shaped clamping blocks 25 and the outer side surface of the cross plate 20.

[0032] For details, please refer to Figure 4 and Figure 5 One end of the bidirectional threaded rod 24 passes through the first support plate 21 and is connected to the turntable 22, and the end of the bidirectional threaded rod 24 away from the first support plate 21 is rotatably connected to the outer side surface of the second support plate 23, and the outer ring surface of the bidirectional threaded rod 24 is threadedly connected to the inner part of the two arc-shaped clamping blocks 25, thereby ensuring that the bidirectional threaded rod 24 is driven to rotate by the turntable 22 to drive the two arc-shaped clamping blocks 25 to move outside the bidirectional threaded rod 24, thereby clamping and fixing the collection bottle 26, making it easy to disassemble the collection bottle 26 and process the collected water.

[0033] The working process of the utility model is as follows: an automatic regulating device for dampening water for offset printing is used. During the use of the device, the liquid level meter 2 can detect the internal storage volume of the water storage barrel 1 at all times, and the flow rate of the water volume in the first pipe 14 can be detected by the flow meter 15. When the flow rate of the water volume in the first pipe 14 is too large or too small, a signal is transmitted to the control device 4 through the data line, and the control device 4 drives the servo motor 13 to rotate forward and reverse, and drives the rotating shaft 11 to rotate through the servo motor 13, thereby driving the elliptical block 12 to rotate. When the elliptical block 12 rotates, it will squeeze the fixed plate 8, and the fixed plate 8 drives the movable plate 7 to move and stretch the two reset springs 6, thereby driving the valve ball 10 away from or close to the interface of the first pipe 14, so as to realize automatic adjustment of the water flow rate in the first pipe 14. When the valve ball 10 is used up, The first pipe 14 and the second pipe 16 are closed, but water will remain on the inner walls of the first pipe 14 and the second pipe 16. The slider 19 is pushed to slide on the outside of the square tube 18 to move the collecting bottle 26 to the bottom of the second pipe 16 to collect the water inside the first pipe 14 and the second pipe 16, thereby avoiding waste and protecting the equipment from pollution. The turntable 22 drives the two-way threaded rod 24 to rotate and drives the two arc-shaped clamping blocks 25 to move on the outside of the two-way threaded rod 24 to clamp and fix the collecting bottle 26, which is convenient for disassembling the collecting bottle 26 to process the collected water. The friction between the arc-shaped clamping blocks 25 and the collecting bottle 26 is increased by arranging the anti-slip pad, and the stability of the arc-shaped clamping blocks 25 moving on the outer ring surface of the two-way threaded rod 24 is increased by the sliding connection between the two arc-shaped clamping blocks 25 and the outer side surface of the cross plate 20.

[0034] 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.
