Problems solved by technology

The disadvantages of this filling method are:
[0011] 2) Before filling the ink, you need to tear off the sticker on the ink cartridge, or open the plug or ball on the ink cartridge, and then insert the needle into the box. After filling the ink, you need to restore the sticker, plug or ball on the ink cartridge. This process is troublesome , and it is easy to damage the structure of the ink cartridge, resulting in permanent damage to the ink cartridge
[0012] 3) The ink injection needle must penetrate into the sponge of the ink cartridge, which destroys the sponge structure, and the number of refills is limited, reducing the repeated service life of the ink cartridge
[0013] 4) When filling ink, the ink filling needle must penetrate into the bottom of the ink cartridge. Improper operation can easily pierce the filter screen in the ink cartridge, resulting in plugging due to the decline in ink filtering effect, resulting in permanent damage to the ink cartridge
[0014] 5) Peristaltic pump ink filling adopts time control and quantification, which requires the consistency and stability of the motor. According to this requirement, the manufacturing cost will be increased
Even if the best DC motor is used, the ink quantitative deviation will occur after a long running time
[0015] 6) There are a large part of the ink cartridges, the inside of the box is not a sponge structure, and the method of injecting needles into the ink cartridges cannot be used, resulting in many ink cartridges that cannot be refilled with this method
[0017] 1) It is only suitable for ink cartridges with nozzles, and almost half of the ink cartridges in the market are ink cartridges without nozzles, which cannot be refilled with this method
[0018] 2) For ink cartridges with nozzles, the nozzles are easily blocked. Once the nozzles are blocked, the ink filling from the nozzles will be very slow, or even completely impossible to inject.
[0019] 3) Due to the positive pressure ink injection, in order to ensure the airtightness of the ink injection pipeline, the pressure resistance of related components and parts must be improved, which increases the equipment manufacturing cost
[0020] 4) The prerequisite for positive pressure ink filling is that the ink cartridge is not blocked. Improper handling of the ink cartridge in the early stage will not complete the ink filling, which will undoubtedly improve the quality requirements of the operators and increase the cost of ink filling services; at the same time, it may also cause ink filling service operators Liability disputes with clients
The implementation is difficult, the manufacturing cost is high, the sales price is also high, and the market is limited
[0022] 6) The nozzle of the ink cartridge will be worn during the positive pressure ink filling process, which will cause the nozzle to deform one by one, resulting in a decline in the printing effect, thus limiting the number of refills
[0024] To sum up, the existing ink refilling equipment has certain defects to varying degrees, not only cannot accurately set the ink refill volume, but also cannot realize completely non-destructive ink refilling of the ink cartridges. Therefore, it is necessary to design a device that can accurately control the ink refill volume of the ink cartridges. And realize the ink filling machine that completely damages the ink cartridge

Embodiment Construction

[0048] Such as Figure 7 , 8 As shown, the peristaltic pump 1 designed by the present invention is assembled by the pump head and the motor 2. After one side of the bracket 3 is assembled with the motor by screws, the other side is assembled with one side of the pump cover, and the other side of the pump cover is equipped with a three-claw bracket. , the three claws of the three-claw bracket are respectively installed with three rollers 4, and the end faces of the rollers are inlaid with iron sheets 5, and the silicone tube 8 is put on two clips and then put into the pump bowl, and the clips are inserted into the U-shaped groove at the bottom of the pump bowl, To fix the silicone tube, buckle the pump bowl with the fixed silicone tube together with the pump cover with the rollers assembled above. At this time, the three rollers tightly squeeze the silicone tube. After assembling the peristaltic pump, the motor shaft passes through the bracket, The pump cover and the motor sha...

Abstract

The invention provides an ink-joiner capable of accurately setting the amount of filled ink and filling ink from an intake passage without damaging an ink box. The end face of a roller wheel of a peristaltic pump is embedded with a metal sheet. The end face of the peristaltic pump is provided with a proximity switch sensor. A silicon rubber gasket arranged on an ink box clamping device is provided with a silicon rubber gasket air gap and a silicon rubber gasket outlet. An end face of press pliers is provided with a nozzle sealing rubber gasket. A centrifuge is provided with a centrifuge turntable which is provided with an ink box support. The ink-joiner has the advantages of: accurately setting the amount of filled ink; only filling an actually needed amount of ink, moving the ink filled in the ink box to an ink outlet mouth of the nozzle through centrifugal treatment, and ensuring no ink leakage of the ink box, complete filling of the ink to the ink outlet mouth and wide application range; preventing the precise clamper and the sealing silicon rubber gasket from color crossing and leakage, avoiding damaging the ink box and a sponge in the ink box during the whole ink filling process and keeping cleanness and convenience; filling ink through a peristaltic pump and having a sensor for accurate amount setting; avoiding amount setting errors caused by errors in the rotation speedof a motor; and improving the recycling times of the ink box to the maximum.

Description

technical field [0001] The invention belongs to an ink injection machine, in particular to an ink injection machine which can accurately set the ink injection volume and inject ink from an air inlet without damaging the ink box. Background technique [0002] With the rapid popularization of computers, the rapid popularization of printers has been driven. In terms of the development of printers, they can be divided into dot matrix printers, laser printers and inkjet printers. Dot matrix printers are gradually being eliminated due to their slow speed, poor precision, and high noise; laser printers are still difficult to popularize quickly due to price issues; color inkjet printers can print various exquisite color pictures and photos, and the printing accuracy exceeds the resolution of human naked eyes. Popularity is extremely fast. Inkjet printers have become the mainstream product in today's printer market, with the highest market share. Due to the rise and rapid developme...
