Description

Technical Field

[0001] This application relates to the field of packaging box printing equipment technology, and in particular to the structure of oil box for packaging box printing equipment. Background Technology

[0002] In the packaging box printing process, the ink box is an important component for storing and supplying printing ink; however, the existing ink box structure has shortcomings.

[0003] The existing ink cartridge structure of packaging box printing equipment often lacks an effective stirring device. As the storage time increases, pigment particles, additives, and other components in the ink are prone to sedimentation and stratification. When using such uneven ink for printing, it will lead to problems such as inconsistent color depth and color saturation in different parts of the packaging box, which seriously affects the quality of the printed products. At the same time, in order to compensate for the color inconsistency, printing companies may need to repeat the printing process, which not only increases ink and time costs but also reduces production efficiency. Therefore, an ink cartridge structure for packaging box printing equipment has been proposed to solve the above problems. Utility Model Content

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses the structure of the ink cartridge in a packaging box printing equipment. (Refer to...) Figure 1-4 The oil box structure of the packaging box printing equipment includes an oil box body 1, a stirring mechanism and a recycling component. The connecting flange 14 of the stirring mechanism is firmly fixed to the inner wall of the top of the oil box body 1. It is connected to a fixing block 17 by multiple fixing rods 15 extending downwards. The bottom of the fixing block 17 is connected to a stator 18. The rotor 20 is rotatably connected inside the stator 18. Multiple shearing holes 19 are distributed on the outer wall of the stator 18. The connecting flange 14 is rotatably connected to a rotating shaft 16. The rotating shaft 16 passes through the fixing block 17 and the stator 18 and is fixed to the rotor 20. The servo motor 21 is installed in the middle of the top of the oil box body 1 and drives the rotating shaft 16 to drive the rotor 20 to rotate. When working, the servo motor 21 starts and the rotor 20 rotates at high speed. The oil is squeezed out through the shearing holes 19 under the action of centrifugal force and is fully mixed evenly under the shearing action of the rotor 20 and the stator 18.

[0022] The recycling component is installed on the oil box body 1. Its discharge port 5 is located on the bottom middle outer wall of the oil box body 1. A manual control valve 6 is installed at the bottom to control the discharge of oil. A circulation pump 7 is fixed on the outer wall of the oil box body 1. The manual control valve 6 is connected to the suction end of the circulation pump 7 through the suction pipe 8. The output end of the circulation pump 7 is connected to the inner cavity of the oil box body 1 through the delivery pipe 9. When oil sediment is found at the bottom of the oil box body 1, the manual control valve 6 is opened and the circulation pump 7 is started. The oil sediment at the bottom is drawn out from the discharge port 5, enters the circulation pump 7 through the suction pipe 8, and is then transported back to the inner cavity of the oil box body 1 by the delivery pipe 9, realizing the recycling and reuse of sedimented oil and avoiding waste.

[0023] The oil container body 1 has an oil outlet 3 on its outer circumferential wall near the bottom. A flow control valve 4 is installed on the outer wall of the oil outlet 3 to regulate the flow of oil delivered to the printing equipment. An oil filling port 10 on the top outer wall is used to add oil. The top of the oil filling port 10 is connected to a sealing cap 11 by a thread to ensure the airtightness of the oil during storage. When adding oil, the sealing cap 11 is opened and tightened after the oil is added. During printing, the flow control valve 4 is adjusted as needed to deliver the well-stirred oil to the printing equipment.

[0024] A liquid level sensor 13 is installed on the inner wall of the oil container body 1 near the top. The liquid level sensor 13 is electrically connected to an external display device. During the use of oil, the liquid level sensor 13 monitors the oil level in real time and transmits the data to the display device. When the liquid level is lower than the set value, the display device issues an alarm to remind the staff to add oil in time to ensure the continuous printing work.

[0025] The top outer wall of the oil container body 1 is equipped with a one-way air inlet valve 12. As the oil is continuously output to the printing equipment, the pressure inside the oil container body 1 decreases, and the one-way air inlet valve 12 automatically opens, allowing outside air to enter and balance the pressure, ensuring smooth output of the oil. When the internal pressure returns to normal, the one-way air inlet valve 12 closes to prevent the oil from evaporating.

[0026] The bottom outer wall of the oil container body 1 is fixedly connected to the fixing frame 2. The fixing frame 2 plays a supporting role, and the oil container body 1 is firmly installed on the printing equipment or work platform to ensure that the oil container body 1 remains stable and does not shake or shift during operations such as stirring and oil delivery.

[0027] The implementation principle of the oil box structure of the packaging box printing equipment in this application embodiment is as follows: open the sealing cover 11 of the oil inlet 10, inject oil into the oil box body 1, the liquid level sensor 13 monitors the liquid level in real time, and tighten the sealing cover 11 after filling.

[0028] Start the servo motor 21, and the stirring mechanism will run. The rotor 20 and stator 18 will work together to shear and stir the oil to make it uniform.

[0029] If sediment is found at the bottom of the oil box body 1 after a period of use, open the manual control valve 6 at the discharge port 5, start the circulation pump 7, extract the sedimented oil and send it back into the oil box body 1 to mix it evenly again.

[0030] According to the needs of the printing equipment, adjust the flow control valve 4 at the oil outlet 3, and the oil is delivered from the oil outlet 3 to the printing equipment. The one-way air inlet valve 12 automatically balances the pressure inside the box to ensure smooth material supply.

[0031] The level sensor 13 continuously monitors the oil level. When the level reaches the set lower limit, it triggers an alarm on the external display device to remind the user to add oil in time.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
