Description

Technical Field

[0001] This utility model relates to a tooling fixture for punching holes in ink cartridges, and more particularly to a punching and ink filling positioning box for recycled ink cartridges. Background Technology

[0002] When printer ink cartridges run out of ink, refilling them for reuse is a common need. Currently, there are two main ways to refill ink cartridges: one is to send the cartridge to the manufacturer for professional refilling, but this involves high time and economic costs. For users who frequently need refills, the accumulated costs are significant and may even negate the economic advantages of refilling. The other method is for users to add ink themselves by drilling holes in the cartridge. For ordinary users, this method has significant drawbacks due to its high operational threshold. Users are not proficient in drilling operations, and due to a lack of professional skills and experience, operational errors are easily made. Once an error occurs, it can not only obstruct the refilling process but also damage the delicate internal structure of the cartridge, rendering it unusable and defeating the purpose of refilling for reuse, while also causing economic losses to the user. In addition, drilling may also damage the cartridge's seal, causing ink leakage and other problems, affecting the normal operation of the printer and the operating environment. Summary of the Invention

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0027] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0028] Reference Figure 1-8 A perforated ink refill positioning box for regenerated ink cartridges includes a base 1, and a cavity 2 for fixing the ink cartridge (such as an ink cartridge) is provided inside the base 1. Figure 4 As shown in C), the side wall of cavity 2 is provided with a positioning group for positioning the ink cartridge. Drilling positioning cover 4 and ink filling positioning cover 5 can be alternately installed on base 1. Drilling positioning cover 4 is provided with positioning hole 6 corresponding to the ink cavity of ink cartridge for guiding the drill bit to process accurately. Ink filling positioning cover 5 is provided with ink filling nozzle 7 corresponding to the position of the drill hole. Ink filling needle 8 is installed in the center of ink filling nozzle 7. Through the alternating installation design of drilling positioning cover 4 and ink filling positioning cover 5, users can easily complete accurate drilling and ink filling operations without professional skills training. This can effectively avoid ink cartridge damage caused by improper operation. At the same time, users no longer need to send ink cartridges back to the manufacturer for repair, which saves time and reduces economic expenditure, perfectly solving the dual problems of time-consuming and expensive ink replenishment needs.

[0029] In this embodiment, the outer diameter of the ink injection needle 8 is smaller than the drilling size of the ink cartridge, so that the gap between the ink injection needle 8 and the drilling hole forms an exhaust channel when the ink cartridge is refilled. At the same time, the ink enters the ink cartridge through the ink injection needle 8 by gravity, and the air inside the ink cartridge is discharged from the exhaust channel. The pressure balance compensation design principle is introduced to automatically adjust the air pressure inside and outside the ink cartridge, instead of increasing the pressure inside the ink cartridge by external pressure. This avoids ink cartridge pressure changes that could lead to ink overflow from the printhead or ink supply interruption.

[0030] Ink cartridges are generally available in single color (such as black) and color (such as 3 colors: cyan, magenta and yellow). When refilling black, there is one positioning hole 6 on the drilled positioning cover 4, which corresponds to the ink chamber where black is located. There is also one ink nozzle 7 on the ink filling positioning cover 5 and one ink filling needle 8 installed in the ink filling nozzle 7. When refilling color, there are three positioning holes 6 on the drilled positioning cover 4, which correspond to the ink chamber where color is located. There are also three ink nozzles 7 on the ink filling positioning cover 5 and three ink filling needles 8 installed in the ink filling nozzle 7. When refilling, the three colors are refilled separately.

[0031] Furthermore, the ink filling positioning cover 5 is marked with an A symbol corresponding to the color of the ink being filled, reducing the possibility of filling errors. Correspondingly, the drilling positioning cover 4 also needs to be marked with an B symbol to prevent drilling errors that could damage the ink cartridge.

[0032] The positioning assembly includes a third positioning part 9 symmetrically arranged on the left and right sides of the cavity 2, a first positioning part 10 located on the front side of the cavity 2, and a second positioning part 11 located on the rear side of the cavity 2. The upper end face of the third positioning part 9 abuts against the upper flange of the ink cartridge (e.g., Figure 8 D is the flange on the ink cartridge. The height of the third positioning part 9 is higher than the height of the largest size of this model of ink cartridge. That is, after this model of ink cartridge is placed, the bottom of the ink cartridge is in a suspended state, thereby avoiding the nozzle at the bottom of the ink cartridge from contacting the bottom of the base 1, which would lead to inaccurate positioning.

[0033] Furthermore, the third positioning part 9 consists of two parallel ribs, and a connecting wall 12 is provided between the ribs on the side closest to the ink cartridge. The third positioning part 9 and the connecting wall 12 form a "U" shaped structure. The upper end of the connecting wall 12 is flush with the top of the third positioning part 9, which increases the area of ​​the top of the third positioning part 9, that is, increases the area supporting the flip-up edge of the ink cartridge. In addition, the connecting wall 12 also has the function of positioning the left and right sides of the ink cartridge.

[0034] The first positioning part 10, the second positioning part 11, and the connecting wall 12 need to be adjusted accordingly for different brands and models of ink cartridges.

[0035] For ink cartridges without flanges, a rib can be provided at the bottom of cavity 2 to contact the bottom of the ink cartridge. The height of the rib needs to be greater than the height of the ink cartridge nozzle so that the nozzle is suspended in the air, preventing the vibration generated during drilling from being transmitted to the nozzle and affecting it.

[0036] The drilling positioning cover 4 is provided with a first anti-misalignment plate 13 corresponding to the second positioning part 11. When the drilling positioning cover 4 is installed in the wrong direction, the first anti-misalignment plate 13 will abut against the first positioning part 10, making it impossible to install the drilling positioning cover 4.

[0037] The bottom edge of the drilling positioning cover 4 is provided with a first positioning edge 18. After the drilling positioning cover 4 is installed, the outer side of the first positioning edge 18 and the first anti-misalignment plate 13 abuts against the inner wall of the cavity 2. It is used for guidance during assembly, improving the accuracy of the installation position of the drilling positioning cover 4, thereby improving the drilling accuracy.

[0038] A column 14 is provided on the drilling positioning cover 4. The positioning hole 6 is located in the center of the column 14 and extends through both ends of the column 14 to increase the depth of the positioning hole 6, thereby preventing the drill bit from tilting during drilling. A reinforcing sleeve 15 is installed inside the column 14. The positioning hole 6 and the reinforcing sleeve 15 are tightly fitted together. The reinforcing sleeve 15 is a metal sleeve. In this embodiment, it is a copper sleeve to prevent the drill bit from damaging the positioning hole 6 during drilling, which could cause the drill bit to tilt or even damage the ink cartridge.

[0039] The ink nozzle 7 has a pinhole in the center, and the ink needle 8 is installed in the pinhole.

[0040] Furthermore, the ink injection needle 8 is fixed to the needle hole with adhesive, which not only serves to fix it but also to seal it.

[0041] Furthermore, the ink nozzle 7 is provided with an extension ring at the pinhole. The inner diameter of the extension ring is the same as the diameter of the pinhole, which increases the length of the pinhole and thus increases the contact area with the ink injection needle 8, preventing the ink injection needle 8 from swinging and causing the upper end of the ink injection needle 8 to fail to cooperate with the ink outlet channel.

[0042] The ink filling positioning cover 5 is provided with a second anti-misalignment plate 17 corresponding to the second positioning part 11. When the ink filling positioning cover 5 is installed in the wrong direction, the second anti-misalignment plate 17 will abut against the first positioning part 10, making it impossible to install the ink filling positioning cover 5.

[0043] The bottom edge of the ink filling positioning cover 5 is provided with a second positioning edge 19. After the ink filling positioning cover 5 is installed, the outer side of the second positioning edge 19 and the second anti-misalignment plate 17 abuts against the inner wall of the cavity 2. It is used for guidance during assembly to improve the accuracy of the installation position of the ink filling positioning cover 5, thereby improving the drilling accuracy.

[0044] Furthermore, the height of the second positioning edge 19 and the second error-proof plate 17 is greater than the length of the ink-filling needle 8 after installation, thus surrounding the ink-filling needle 8 to form a safety barrier and prevent punctures.

[0045] The base 1 has symmetrical notches 20 on the left and right sides for holding the ink cartridge by hand, making it easy to take out the ink cartridge after it has been refilled.
