Description

Technical Field

[0001] The utility model relates to the technical field of print head cleaning, and specifically, to a print head for printing packaging printed matter. Background Art

[0002] After retrieval, the patent with the publication number CN213704928U discloses a print head for printing packaging printed matter. When the print head needs to be cleaned, turn the crank. The rotation of the crank drives the rotation of the rotating shaft, the rotation of the rotating shaft drives the rotation of the gear, the rotation of the gear drives the strip plate to slide downward, and at the same time, the slider slides downward on the slide rod. The downward sliding of the slider drives the cleaning liquid tank to move downward, and the downward movement of the cleaning liquid tank drives the print head to move into the cleaning tank. When the print head is inside the cleaning tank, open the valve to allow the cleaning liquid in the cleaning liquid tank to flow into the cleaning tank from the drain pipe, and soak the print head inside the cleaning tank, avoiding the problem that the cleaning head of the existing printing equipment is cleaned manually, and it is easy to scratch the print head during the scrubbing process and the cleaning effect is not good enough.

[0003] When the above device soaks and cleans the print head in the cleaning tank, the lack of auxiliary cleaning tools will lead to poor cleaning effect. The main reason is that the cleaning liquid inside the cleaning tank does not flow sufficiently. Especially without the help of additional cleaning tools, the cleaning liquid cannot completely cover and thoroughly rinse the surface of the print head, which will cause dirt to remain on the print head and affect the cleaning effect. Therefore, a print head for printing packaging printed matter is needed. Content of the Utility Model

[0024] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0025] The print head of an ink - jet printing device is prone to clogging problems due to the long - term retention of ink. Therefore, it is necessary to clean the print head regularly. This is because the ink will gradually dry or accumulate other impurities in the small spray holes and nozzles of the print head, affecting the normal ejection of the ink. Regular cleaning can help keep the nozzles unblocked and ensure the printing quality and stability.

[0026] When the existing device soaks the print head in a cleaning tank for cleaning, the lack of auxiliary cleaning tools will lead to poor cleaning effect. The main reason is that the cleaning liquid flow inside the cleaning tank is not sufficient. Especially without the help of additional cleaning tools, the cleaning liquid cannot completely cover and thoroughly rinse the surface of the print head, which will cause dirt to remain on the print head and affect the cleaning effect. Please refer to Figures 1 - 5, An embodiment provides a print head for printing packaging printed matter, including a cleaning tank 1 and a cleaning liquid filled inside the cleaning tank 1. Inside the cleaning tank 1, there is a storage mesh plate 2 for placing the print head. The distance between the storage mesh plate 2 and the inner bottom wall of the cleaning tank 1 is between 10 cm and 15 cm, and a number of circulation holes are opened at the bottom of the storage mesh plate 2, which can further increase the contact area between the cleaning liquid and the print head.

[0027] Reference Figures 2 - 3 As shown in the figure, when the existing device immerses the print head in the cleaning tank for soaking and cleaning, the lack of auxiliary cleaning tools will lead to poor cleaning effect. The main reason is that the cleaning liquid inside the cleaning tank does not flow sufficiently. Especially without the help of additional cleaning tools, the cleaning liquid cannot completely cover and thoroughly rinse the surface of the print head, which will cause dirt to remain on the print head and affect the cleaning effect. A cleaning mechanism 4 for enhancing the cleaning effect of the print head is provided at the rear side of the cleaning tank 1. The cleaning mechanism 4 includes an ultrasonic generator 41 fixed to the rear side of the cleaning tank 1, and two ultrasonic receivers 42 are symmetrically and fixedly installed on both sides of the cleaning tank 1. The ultrasonic generator 41 is electrically connected to the two ultrasonic receivers 42. After placing the print head on the storage mesh plate 2, the power supply of the ultrasonic generator 41 is plugged in. The ultrasonic generator 41 causes the two ultrasonic receivers 42 to generate ultrasonic waves, so that the cleaning liquid in the cleaning tank 1 generates ultrasonic waves to clean the print head. When the ultrasonic waves propagate into the cleaning liquid, a cavitation effect will occur, and a large number of tiny bubbles will be formed in the liquid. These bubbles are formed in the high-pressure area and then quickly collapse in the low-pressure area. The energy released when the bubbles collapse can generate high-temperature and high-pressure shock waves, effectively cleaning the surface and tiny pores of the print head, decomposing and rinsing off the dirt attached to the print head; when the ultrasonic waves propagate in the liquid, a micro-flow effect will occur, which will cause tiny flows inside the liquid. This micro-flow can push the cleaning liquid to all surfaces and tiny structures of the print head, helping to thoroughly clean and preventing dirt from remaining on the print head; the change in surface tension during the propagation of ultrasonic waves enables the cleaning liquid to fully cover the entire surface of the print head, including the uneven parts and tiny pores on the surface, ensuring that the cleaning liquid can enter all areas that need to be cleaned, thereby thoroughly cleaning the print head and preventing dirt from remaining.

[0028] Reference Figures 2 - 5As shown in the figure, a cleaning liquid purification and circulation mechanism 5 for removing impurities from the cleaning liquid is provided on one side of the cleaning tank 1 close to one of the ultrasonic receivers 42. The cleaning liquid purification and circulation mechanism 5 includes a water pump 51 fixed to the side of the cleaning tank 1. The water intake end of the water pump 51 is fixedly connected and communicated with a purification cylinder 52. The end face of the purification cylinder 52 is fixedly connected and communicated with a liquid suction pipe 53 fixedly connected to the inside of the cleaning tank 1. The water outlet end of the water pump 51 is fixedly connected and communicated with a coil pipe 54. When the cleaning mechanism 4 removes the dirt on the surface of the print head, the water pump 51 is started. The cleaning liquid is pumped out by the water pump 51 and can effectively remove solid particles, sediments or other impurities in the cleaning liquid through the purification cylinder 52. If these impurities are not removed, they may be deposited on the surface of the print head again, affecting the cleaning effect. The cleaning liquid treated by the purification cylinder 52 can return to the cleaning tank 1 through the coil pipe 54 to form a cycle for reuse.

[0029] Reference Figure 5 As shown in the figure, a rotating shaft 521 is rotatably connected to the inside of the purification cylinder 52. The outer wall of the middle end of the rotating shaft 521 is fixedly connected with a flow-facing blade 522. The outer walls of both ends of the rotating shaft 521 are symmetrically and fixedly connected with two support plates 523. The end faces of the two support plates 523 are fixedly connected with a screen cleaning brush 524. A filter screen 525 is fixedly installed inside the purification cylinder 52. When the cleaning liquid enters the purification cylinder 52 and impacts the flow-facing blade 522, the rotating shaft 521 rotates. The rotation of the rotating shaft 521 causes the screen cleaning brush 524 to rotate to clean the filter screen 525 on the impurity-facing side during the filtering process.

[0030] Reference Figures 3 - 4As shown in the figure, two assembly mechanisms 3 for installing the storage mesh plate 2 inside the cleaning box 1 are symmetrically arranged at the top on both sides of the cleaning box 1. The assembly mechanism 3 includes a positioning plate 31 fixed to the top of the storage mesh plate 2. Two trapezoidal plates 33 are symmetrically and slidably connected inside the positioning plate 31. On the opposite sides of the two trapezoidal plates 33, a first spring 34 is fixedly connected to each. The opposite ends of the first spring 34 are fixedly connected to the inner wall of the positioning plate 31. Two movable rods 36 are hinged to the bottom of the positioning plate 31. The bottom ends of the two movable rods 36 are both hinged with an inverted T-shaped transverse moving block. A second spring 32 is fixedly connected between the inverted T-shaped transverse moving blocks. A U-shaped plate 35 is provided at the bottom of the inverted T-shaped transverse moving block. The top end of the U-shaped plate 35 contacts the side surface of the trapezoidal plate 33. An inverted T-shaped transverse moving groove for the inverted T-shaped transverse moving block to slide horizontally is opened on the inner bottom wall of the U-shaped plate 35. When the storage mesh plate 2 is installed in the cleaning box 1, the two trapezoidal plates 33 are aligned with the rectangular groove opened at the top of the cleaning box 1 and placed in. The two trapezoidal plates 33 enter the positioning plate 31 by squeezing the first spring 34. When the two trapezoidal plates completely pass through the rectangular groove, they are clamped by the reset of the first spring 34, thus completing the installation of the storage mesh plate 2. When disassembling the storage mesh plate 2, when the U-shaped plate 35 is pushed upward, the inverted T-shaped transverse moving blocks at the bottom ends of the two movable rods 36 both slide in the inverted T-shaped transverse moving groove and stretch the second spring 32, so that the top end of the U-shaped plate 35 moves upward to push the two trapezoidal plates 33 to enter the positioning plate 31 again. By pulling up the positioning plate 31, the storage mesh plate 2 can be disassembled.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
