Description

Technical Field

[0001] This utility model relates to the field of ink cartridge manufacturing technology, and in particular to an ink cartridge cleaning device. Background Technology

[0002] In modern office and printing industries, ink cartridges are essential printing consumables used in enormous quantities. To reduce costs and environmental pollution, more and more factories are beginning to recycle and reuse used ink cartridges. After recycling, ink cartridges need to be thoroughly cleaned to remove residual ink, impurities, etc., so that they can be refilled and used normally.

[0003] Currently, factories generally use low-pressure water guns to clean ink cartridges. Before cleaning, multiple ink cartridges must be placed in specific retaining slots with the nozzles facing upwards. During cleaning, the low-pressure water gun sprays water from the bottom upwards, and the water flow passes through the retaining slots to rinse the ink cartridges. The low-pressure water flow effectively removes stubborn stains inside the ink cartridges, ensuring cleaning efficiency.

[0004] However, in actual cleaning processes, the water jet from the low-pressure water gun, spraying upwards from the bottom, has a certain impact force. The ink cartridge, simply placed within the retaining groove, is easily dislodged by this force. Once the cartridge detaches, it not only interrupts the cleaning process and reduces efficiency but may also damage the cartridge, increasing recycling costs. Furthermore, accidental cartridge detachment can pose safety hazards to operators, such as injuring their feet. Moreover, operators may need to expend extra effort to secure the cartridge, further increasing labor costs and operational difficulty. Frequent cartridge detachment also leads to discontinuity in the cleaning operation, significantly reducing the stability and efficiency of the entire process and hindering large-scale cartridge recycling and cleaning. Additionally, the side of the cartridge with the nozzle has a stepped structure with varying heights. If a standard retaining block is used, the stepped shape makes it prone to damaging the cartridge when applying force. Moreover, the large area of ​​a standard retaining block can clog the nozzle when used for retaining, preventing the low-pressure water gun from effectively cleaning it. Utility Model Content

[0005] The present invention aims to provide an ink cartridge cleaning device to solve the problems of easy displacement of existing ink cartridges and obstruction of nozzle cleaning, which prevents complete cleaning.

[0006] The ink cartridge cleaning device in this solution includes a cleaning frame. A movable plate is horizontally slidably connected to the bottom of the cleaning frame. Multiple low-pressure water guns are mounted on the movable plate. A limit plate is fixedly connected to the movable plate. The limit plate has multiple limiting slots for preventing ink cartridges from moving. A fixed plate is located at the top of the cleaning frame. The fixed plate is connected to a vertical cylinder that drives it to move up and down. The fixed plate is connected to multiple limiting components. The limiting components include two symmetrically arranged positioning plates. The positioning plates face the limiting slots, and the side of the positioning plates facing the limiting slots is stepped.

[0007] The working principle and beneficial effects of this solution are as follows: During use, the operator stands in front of the cleaning rack and manually moves the moving plate in front of them to facilitate the placement of ink cartridges. Then, the ink cartridges are placed one by one into the limiting slots on the limiting plate, ensuring that the side of the ink cartridge with the nozzle faces upwards and the circuit contact area faces the operator. After placing the ink cartridges, the moving plate is manually slid so that multiple ink cartridges correspond to different limiting components. At this point, two symmetrically distributed, stepped positioning plates on each limiting component, located near the limiting slot, will be positioned on both sides of the upper surface of the ink cartridge. The vertical cylinder is activated, driving the fixing plate to move the limiting components downwards until the positioning plates securely hold the ink cartridge between the limiting slot and the positioning plates. Finally, multiple low-pressure water guns on the moving plate are turned on, and water flows from bottom to top to rinse the inside of the ink cartridge. Because the positioning plates are located on both sides of the upper surface of the ink cartridge, they do not obstruct the rinsing of the nozzle in the middle of the upper surface of the ink cartridge, allowing water to flow smoothly through the nozzle and achieve a thorough cleaning of the ink cartridge. In this solution, the positioning plate is designed to precisely fit the stepped shape of the ink cartridge surface. Combined with the limiting groove, it vertically limits the ink cartridge, effectively preventing displacement during cleaning. Simultaneously, this design does not obstruct nozzle cleaning, ensuring that water from the low-pressure water gun flows smoothly through the nozzle for comprehensive cleaning of the ink cartridge.

[0008] Furthermore, the limiting component also includes a connecting block, which is detachably connected to the fixing plate. Side plates are fixedly connected to both sides of the connecting block, and two positioning plates are located between the two side plates, with the positioning plates fixedly connected to the connecting block. When the connecting block moves downwards with the fixing plate, the side plates will be positioned on both sides of the ink cartridge, and the bottom of the side plates will contact the limiting plate, thereby limiting the horizontal movement of the ink cartridge. In addition, due to the detachable nature of the connecting block and the fixing plate, different sizes of ink cartridges can be adapted by replacing the limiting component.

[0009] Furthermore, the side plate and positioning plate are sloped near the ink cartridge nozzle. This sloped design effectively prevents the cleaning fluid ejected from the nozzle from being blocked by the side plate and positioning plate, thus avoiding residue between them.

[0010] Furthermore, the low-pressure water gun is connected to a pressure regulating valve. The pressure of the water sprayed from the low-pressure water gun can be adjusted by the pressure regulating valve.

[0011] Furthermore, drainage grooves are provided on both sides of the bottom of the cleaning rack. This design facilitates rapid drainage.

[0012] Furthermore, the movable plate is connected to a transverse cylinder that drives its horizontal movement. Using the transverse cylinder to drive the movement of the movable plate allows for more precise positioning of the low-pressure water gun. Attached Figure Description

[0018] The following detailed explanation illustrates the specific implementation methods:

[0019] The reference numerals in the accompanying drawings of the instruction manual include: 1. cleaning frame; 2. vertical cylinder; 3. fixing plate; 4. connecting block; 5. side plate; 6. positioning plate; 7. ink cartridge; 8. limiting plate; 9. low-pressure water gun; 10. moving plate; 11. drainage trough; 12. connecting trough.

[0020] The basic implementation examples are as follows: Figures 1-5As shown: An ink cartridge cleaning device includes a cleaning frame 1. Drainage grooves 11 are provided on both sides of the bottom inner side of the cleaning frame 1. A movable plate 10 is horizontally slidably connected to the middle of the bottom inner side of the cleaning frame 1. The movable plate 10 is connected to a horizontal cylinder that drives its horizontal movement. The horizontal cylinder is fixed to the cleaning frame 1. Six low-pressure water guns 9 are provided on the movable plate 10. The low-pressure water guns 9 are connected to pressure regulating valves. A limiting plate 8 is fixedly connected to the movable plate 10. The limiting plate 8 has multiple limiting slots for preventing ink cartridges 7 from being moved. The limiting slots include placement slots and connecting slots 12 that are narrower than the placement slots and communicate with them. The inner side of the cleaning frame 1... A fixed plate 3 is provided at the top, and a vertical cylinder 2 is connected to the fixed plate 3 to drive it to move up and down. The vertical cylinder 2 is fixedly connected to the upper surface of the cleaning rack 1. Six limiting members are fixedly connected to the fixed plate 3. The limiting members include connecting blocks 4, which are bolted to the fixed plate 3. Side plates 5 are fixedly connected to both sides of the connecting blocks 4. Two symmetrical positioning plates 6 are provided between the two side plates 5. The positioning plates 6 are close to the side plates 5 and are fixedly connected to the connecting blocks 4. The positioning plates 6 face the limiting through groove. The side of the positioning plates 6 facing the limiting through groove is stepped. The side plates 5 and the positioning plates 6 are inclined at the positions near the nozzle of the ink cartridge 7.

[0021] In use, the operator stands in front of the cleaning rack 1 and activates the horizontal cylinder. The horizontal cylinder drives the moving plate 10 to move in front of the operator, making it easier for the operator to place the ink cartridges 7. Then, the ink cartridges 7 are placed one by one into the placement slots of the limiting through grooves on the limiting plate 8. The ink cartridges 7 are then placed on the placement slots, ensuring that the side of the ink cartridge 7 with the nozzle is facing upwards and the circuit contact area of ​​the ink cartridge 7 is facing the operator. After placing the ink cartridges 7, the horizontal cylinder is activated to move the moving plate 10 away from the operator, so that the ink cartridges 7 on the limiting plate 8 correspond to different limiting components. Furthermore, due to the detachable nature of the connecting block 4 and the fixing plate 3, different sizes of ink cartridges 7 can be adapted by replacing the limiting components. Activating the vertical cylinder 2 drives the fixing plate 3, causing the limiting components to move downwards. As the connecting block 4 moves downwards with the fixing plate 3, the side plates 5 will be positioned on both sides of the ink cartridge 7, with their bottoms contacting the limiting plate 8, thereby limiting the horizontal direction of the ink cartridge 7. Meanwhile, one side of the step on the positioning plate 6 fixes the upper surface of the ink cartridge 7, vertically positioning it. The positioning plate 6 securely limits the ink cartridge 7 between the limiting groove and the positioning plate 6. Finally, the six low-pressure water guns 9 on the moving plate 10 are simultaneously activated, and water flows from bottom to top through the connecting groove 12 to rinse the inside of the ink cartridge 7. Because the positioning plate 6 is located on both sides of the upper surface of the ink cartridge 7, it does not obstruct the rinsing of the nozzle in the middle of the upper surface of the ink cartridge 7, allowing water to flow smoothly through the nozzle and achieve a thorough cleaning of the ink cartridge 7. In this solution, the positioning plate 6 is designed according to the stepped shape of the ink cartridge 7 surface, ensuring a precise fit. With the addition of a limiting groove, the ink cartridge 7 can be vertically limited, effectively preventing it from shifting during cleaning. Simultaneously, this design does not obstruct nozzle cleaning, ensuring that water from the low-pressure water gun 9 flows smoothly through the nozzle, achieving comprehensive cleaning of the ink cartridge 7. The cleaning agent is then discharged from the drain trough 11.

[0022] Keep the nozzle of the low-pressure water gun 9 at a distance of 20-30 cm or more from the ink cartridge 7, and adjust the pressure to less than 50 psi using the pressure regulating valve.
