Description

Printer cleaning system

Technical Field

The present disclosure relates to cleaning systems, and particularly to a printer cleaning system.

Background

The printer cleaning system is a system for maintaining print quality and nozzle adequacy. The printer cleaning system mainly comprises an ink stack, a scraper component and the like.

Generally, the ink stack can be divided into a lifting type and a swinging arm type, and the scraper assembly can be divided into a fixed type and a reciprocating type, but the problems of ink splashing, pollution and the like exist no matter what type is adopted. Specifically, because the ink stack and the scraper assembly are independently controlled to perform ink pumping and dirt scraping actions, the structure is independent and complex, and the movement error is large. In addition, the ink stacks and the scraper assemblies which operate independently use more materials, so that the assembly cost is higher. Furthermore, since the two are operated independently, the driving is also performed independently, so that it is difficult to precisely control and adjust the contact area and the cleaning force during cleaning, thereby causing an unpredictable pollution problem.

Therefore, how to develop a printer cleaning system capable of precisely and synchronously controlling the lifting and contact area and further preventing and treating the pollution problem is a problem yet to be solved at present.

Disclosure of Invention

It is a primary object of the present invention to provide a printer cleaning system to solve and improve the above-mentioned problems and disadvantages of the prior art.

Another objective of the present invention is to provide a printer cleaning system, which can drive the ink stack assembly to the ink stack cleaning position and simultaneously drive the scraper assembly to a scraper return position by rotating the transmission device at a first angle, a second angle and a third angle; driving the ink stack assembly to an ink stack resetting position, and simultaneously driving the scraper assembly to a scraper cleaning position; and enabling the ink stack assembly to be at the ink stack resetting position, and simultaneously enabling the scraper assembly to be also driven to be at the scraper resetting position. In other words, the printer cleaning system of the invention can continuously and separately perform actions such as stack cleaning, scraper cleaning and resetting through different phases of the transmission device, and because the actions are operated alternately and continuously, the error of the movement is extremely small, the cleaning effect is effectively improved, and meanwhile, the pollution problem is prevented and treated.

Another object of the present invention is to provide a printer cleaning system, which can be driven by only a single driving device through the special design of the transmission device, not only uses a few material parts, but also has relatively low assembly cost, and can achieve the effects of precisely controlling and adjusting the contact area and cleaning force during cleaning due to the simple control of the single driving device.

To achieve the above object, a preferred embodiment of the present invention provides a printer cleaning system, including: a cleaning base, an ink stack component, a scraper component, a transmission device and a driving device. The cleaning base is provided with a first accommodating groove and a second accommodating groove, wherein the first accommodating groove is arranged adjacent to the second accommodating groove. The ink stack assembly is disposed in the first accommodating groove. The scraper component is arranged in the second accommodating groove. The transmission device penetrates through the first accommodating groove and the second accommodating groove and is connected with the ink stack assembly and the scraper assembly. The driving device is connected with the transmission device to drive the transmission device. When the transmission device rotates at a first angle, the ink stack assembly is driven by the transmission device to be in an ink stack cleaning position, and the scraper assembly is driven by the transmission device to be in a scraper resetting position.

Compared with the prior art, the invention has the beneficial effects that: the printer cleaning system can continuously and separately perform actions such as ink stack cleaning, scraper cleaning, resetting and the like by rotating the transmission device at different angles, and because the actions are operated interactively and continuously, the movement error is extremely small, the cleaning effect is effectively improved, and meanwhile, the pollution problem is prevented and treated.

Referring to fig. 6, a detailed structural diagram of a transmission device of a printer cleaning system according to another preferred embodiment of the invention is shown. As shown in fig. 6, the transmission device of the present invention can also be modified to a transmission device 9, wherein the transmission device 9 includes a polygonal shaft 91, a first receiving portion 92, two first round handles 93, a first connecting rod 94, a transmission rod 95, two second round handles 96, a second connecting rod 97, a second receiving portion 98 and a fixing shaft 99.

In other words, the printer cleaning system of the present invention has different phases by rotating the transmission device at different angles, and can continuously and separately perform the actions of stack cleaning, scraper cleaning, reset, etc., and since the actions are operated alternately and continuously, the error of the movement is very small, so that the cleaning effect is effectively improved, and the contamination problem is prevented. Furthermore, through the special design of the transmission device, the printer cleaning system can be driven by only a single driving device, not only fewer materials are used, but also the assembly cost is relatively low, and meanwhile, because the control of the single driving device is simpler, the effects of accurately controlling and adjusting the contact area and the cleaning force during cleaning and the like can be achieved.
