Description

How to fill the toner cartridge

The present invention relates to toner cartridges for electronic imaging devices, and more particularly to a method of filling the toner cartridge.

General electronic imaging devices such as laser printers often use toner as a printing raw material. In order to facilitate the replenishment of toner, toner is often filled in a toner cartridge and then placed in the printer for use as toner. After it is used up, replace it with a new toner cartridge filled with toner. In this way, the operation of replenishing toner is very convenient, and ordinary consumers can replace it by themselves without the assistance of professional technicians.

However, the replaced toner cartridge usually needs to be recycled by the manufacturer to refill the toner with toner. Otherwise, it has to be discarded, which is neither economical nor environmentally friendly. Therefore, some manufacturers provide toner refill packs for consumers to Fill the toner into the original toner cartridge by yourself, but the structure of the current refill pack is not perfect, which makes the filling operation inconvenient for users. Not only the operation procedures are complicated, but also there are often problems of toner leakage, contamination and excessive residual powder. Or the structure of the toner refill pack itself is relatively complex. Although the operation is relatively simple, the cost is high and the waste is still formed when discarded after use. Therefore, how to simultaneously achieve easy operation, no leakage of toner filling, low cost and environmental protection has become an urgent problem to be solved in the industry.

One object of the present invention is to provide a method for filling a toner cartridge, which is not only simple and convenient to operate, but also can reliably fill the toner without leakage. Another object of the present invention is to provide a method for filling a toner cartridge that can reduce the amount of residual toner. , low cost and environmentally friendly.

In order to achieve the above object, the method of filling a toner cartridge of the present invention includes the following steps: (a) taking a powder container containing toner, the powder container has an opposite first end and a second end, Form a powder outlet at the first end of the powder container; (b) Take a toner cartridge with an opening at one end, and cover the toner cartridge with its opening from the first end to the second end of the powder container (c) forming an air vent at the second end of the powder container; (d) pulling out the powder container from the inside of the toner cartridge, and the toner in the powder container will be separated from the powder outlet The toner container remains inside the toner cartridge; and (e) a cover is taken to close the opening of the toner cartridge. Therefore, the method for filling the toner cartridge provided by the present invention is not only simple and convenient to operate, but also can reliably fill the toner without leakage and reduce the amount of residual powder. It is also low-cost and environmentally friendly.

The following is a detailed description of the technical content and features of the present invention through a preferred embodiment and drawings. As shown in Figures 1 to 5, it is a method for filling a toner cartridge provided by a preferred embodiment of the present invention, including: Following steps:

Step (a): Take a powder container 20 containing toner 10. The powder container 20 is made of soft plastic material and is cylindrical with an opposite first end 21 and a second end 22. In order to facilitate placing the toner container 20 into the elongated toner cartridge 40, a shaping sheet 30 can be wound around the powder container 20. The shaping sheet 30 is made of a hard plastic material such as polyethylene. Made of ethylene phthalate (PET), the outside of the powder container 20 can be restricted to form a cylindrical shape with a flat surface, and the shaping piece 30 can even be placed into a tubular fixture together with the powder container 20 32, since the shaping piece 30 covers one end of the powder container 20, the powder container 20 can smoothly extend into the tubular fixture 32, and then the first end 21 of the powder container 20 is connected to the second end of the powder container 20. Both ends 22 are exposed from the tubular fixture 32. Since the diameter of the tubular fixture 32 is fixed and made of a relatively hard plastic material such as polyethylene terephthalate (PET), the powder container 20 can be The diameter is limited, so that it can be more conveniently placed into the toner cartridge 40 in subsequent steps. In other embodiments, the powder container 20 itself can be made of a relatively hard plastic material such as polyethylene terephthalate (PET). In this case, there is no need to use the shaping sheet 30 or the tubular fixture 32. In subsequent steps, the toner cartridge 40 can be smoothly placed into the toner cartridge 40 , or the toner cartridge 40 can be smoothly placed into the tubular fixture 32 without the aid of the shaping piece 30 . As shown in Figure 2, in this step, the powder container 20 is placed in an upright position, with the first end 21 of the powder container 20 facing upward, and the second end 22 inserted into a fixed cylinder 36. The fixed cylinder 36 A bottom plate 38 can be placed on the table or the ground to keep the powder container 20 upright. Then, a powder outlet 23 is formed on the first end 21 with scissors, a blade or other methods, and the powder container 20 is placed in an upright position. The first end 21 of the container 20 is folded toward the second end 22, as shown in Figure 3, so that the powder outlet 23 is temporarily closed to avoid powder leakage when the toner cartridge 40 is placed in the powder container 20. condition. However, in other embodiments, the above steps of erecting or folding can be omitted, or the powder container 20 can be directly held upright without the assistance of the fixed tube 36 .

Step b: Take a toner cartridge 40 and its bottom end 41 has an opening 42. The toner cartridge 40 is fitted with its opening 42 from top to bottom from the first end 21 to the second end 22 of the toner container 20. , put the powder container 20, the shaping piece 30 and the tubular fixture 32 together into the toner cartridge 40, as shown in Figure 3; then put the toner cartridge 40 together with the powder container 20, the shaping piece 30 and the tubular fixture. Take out the tool 32 from the fixed cylinder 36 together, flip the toner cartridge 40 up and down, and then put the top end 43 of the toner cartridge 40 downward into the fixed cylinder 36. At this time, the second end 22 of the toner container 20 faces upward and Exposed on the toner cartridge 40, as shown in Figure 4.

Step c: Form an air vent 24 in the second end 22 of the powder container 20 by shearing, cutting or other methods.

Step d: Pull out the powder container 20, the shaping piece 30 and the tubular fixture 32 together or individually from the inside of the toner cartridge 40. The toner 10 in the powder container 20 is ejected from the powder due to gravity or inertia. The port 23 is separated from the powder container 20 and remains inside the toner cartridge 40. Since the ventilation port 24 allows air to enter the powder container 20 from the second end 22, it can prevent the toner 10 from being unable to pass through the powder outlet due to a vacuum phenomenon. 23The situation of outflow is shown in Figure 4. In other embodiments, the shaping piece 30 and/or the tubular fixture 32 are extracted from the inside of the toner cartridge 40 before step (c).

Step e: Finally, take a cover 44 to close the opening 42 of the toner cartridge 40 to complete the filling operation of the toner cartridge, as shown in FIG. 5 .

Through the above design, the method of filling the toner cartridge provided by the present invention is simple and convenient to operate. The toner 10 can be reliably filled into the toner cartridge 40 without leakage. Moreover, the simple structure of the toner container 20 can reduce the cost after filling. In addition, the cost of the instruments and devices used in the method of the present invention is very low, and the amount of waste after filling the toner is also very small, taking into account the requirements of environmental protection, thereby achieving the purpose of the present invention.
