Description

Technical Field

[0001] The present disclosure relates to the field of printing equipment, and in particular to a nozzle module maintenance mechanism and a printing equipment having the same. Background Art

[0002] In the field of inkjet printing, whether industrial-grade inkjet printers can work stably for a long time directly affects the economic benefits of printing production companies. Therefore, how to improve the working efficiency of printing equipment has always been an eternal topic pursued by printer manufacturers. There are many ways to improve the working efficiency of inkjet printers, such as using faster and more efficient nozzles, improving the automation of printers, optimizing software to reduce bugs, reducing downtime maintenance and auxiliary time, etc. At present, with the general improvement of the research and development level of inkjet printer manufacturers, the upgrade potential in product software, automation level and other directions has been almost exhausted. Therefore, in addition to adopting more efficient nozzle technology, how to quickly perform daily maintenance on the nozzles of inkjet printers, reduce maintenance time, and improve the automation of nozzle maintenance has become the main direction of printer manufacturers. In response to this problem, at this stage, whether it is ONEPASS inkjet printing equipment or multi-PASS inkjet printing equipment, most of them still stay in the way of manually assisting the cleaning of the nozzles or moving the entire nozzle module out of the printing operation area (the nozzle cleaning mechanism is installed outside the printing area) to automatically clean the nozzles. This type of nozzle cleaning operation often requires a long period of downtime maintenance, which greatly reduces the production efficiency of the equipment. Especially in applications where multiple independent nozzle modules are installed on a single horizontal transmission component (such as industrial inkjet printers), the daily cleaning problem of the nozzle is more prominent. The mainstream equipment in the industry is still in a semi-automatic state, requiring manual cooperation to clean the nozzle, and the application experience is poor. Summary of the invention

Fig.12 The structure diagram of the receiving box of the nozzle module maintenance mechanism of the embodiment of the present disclosure is shown, which is provided with an active cleaning mechanism and a negative pressure cleaning mechanism. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 or Fig.10 As shown, the nozzle module maintenance mechanism includes: a fixed frame 100, a driving device, a telescopic device 200 and a receiving box 300, wherein the fixed frame 100 is used to be fixedly mounted on the bottom of the nozzle module mounting bracket 700, the driving device is fixedly mounted on the fixed frame 100, the telescopic device 200 is fixedly mounted on the driving end of the driving device, the telescopic device 200 is horizontally arranged, the driving device drives the telescopic end of the telescopic device 200 to telescope, and the telescopic end of the telescopic device 200 telescopes toward the lower side of the nozzle module. The receiving box 300 is fixedly mounted on the telescopic end of the telescopic device 200, and the top of the receiving box 300 is provided with an opening facing the print nozzle in the nozzle module, so that the waste ink discharged from the nozzle in the nozzle module flows into the cavity of the receiving box 300 through the opening at the top of the receiving box 300. Here, it should be pointed out that the telescopic stroke of the telescopic device 200 is set by the distance from the fixed position of the telescopic device 200 to the nozzle installed in the nozzle module.

[0044] The nozzle module maintenance mechanism of the embodiment of the present application is fixedly installed below the nozzle module mounting bracket 700 through the fixing frame 100, and can follow the horizontal movement of the nozzle module as a whole. When the nozzle module needs to be cleaned and maintained, the nozzle module maintenance operation is turned on, and the driving device is turned on, thereby driving the telescopic device 200 to extend, and the receiving box 300 is ejected from the nozzle module mounting bracket 700 under the drive of the telescopic device 200, and extends to the bottom of the nozzle module. At this time, the nozzle in the nozzle module performs a series of cleaning actions such as ink pressing and flash spraying, and the ink sprayed by the nozzle module will flow into the cavity of the receiving box 300 through the opening above the receiving box 300. When the nozzle maintenance operation is completed, the driving device drives the telescopic device 200 to retract, and the receiving box 300 is retracted to the bottom of the nozzle module mounting bracket 700 under the drive of the telescopic device 200, completing the cleaning and maintenance of the nozzle module. The nozzle module maintenance mechanism of the embodiment of the present application is targeted at the working principle of the nozzle of the inkjet printer, and the nozzle module maintenance mechanism of the embodiment of the present application is set at a position close to the nozzle. When the nozzle of the inkjet printer needs daily maintenance, only a simple process is needed to automatically complete the maintenance preparation work. At the same time, the nozzle module maintenance mechanism of the embodiment of the present application can cooperate with the subsequent ink pressing, flash spraying and other waste discharge actions of the nozzle. In summary, the nozzle module maintenance mechanism of the embodiment of the present application is simple and fast in the process of cooperating with the nozzle to perform maintenance and cleaning operations, and can quickly complete the nozzle cleaning and maintenance operations, which greatly reduces the time for nozzle cleaning and maintenance, improves the production efficiency of the equipment, and adopts an automatic structure without manual assistance.

[0045] In a possible implementation, the nozzle module maintenance mechanism of the embodiment of the present application further includes an ink cartridge 400 and a waste discharge pipe 500. The ink cartridge 400 is fixedly mounted on the bottom of the fixing frame 100, and the driving device is fixedly mounted on the top of the fixing frame 100, so that the telescopic device 200 is located above the ink cartridge 400, and the receiving box 300 is located above the ink cartridge 400. The top of the ink cartridge 400 is provided with an opening, and the interior of the ink cartridge 400 is an ink storage cavity. The waste discharge pipe 500 is fixed on the receiving box 300, one end of the waste discharge pipe 500 is connected to the receiving box 300, and the other end of the waste discharge pipe 500 extends into the ink storage cavity of the ink cartridge 400. The waste discharge pipe 500 is connected to the ink storage cavity of the ink cartridge 400, so that the waste ink in the receiving box 300 can flow into the ink storage cavity of the ink cartridge 400 through the waste discharge pipe 500.

[0046] The setting of the ink storage cartridge 400 can increase the volume of waste ink carrying the nozzle module. When the receiving box 300 receives the waste ink flowing out of the nozzle, the waste ink will flow into the ink storage cavity of the ink storage cartridge 400 through the waste discharge pipe 500. Therefore, the cavity for storing waste ink is increased by setting the ink storage cartridge 400.

[0047] Furthermore, in a possible implementation, the nozzle module maintenance mechanism of the embodiment of the present application also includes a waste cleaning tube 600, one end of which extends into the ink storage cavity of the ink storage cartridge 400 to connect the waste cleaning tube 600 with the ink storage cavity of the ink storage cartridge 400.

[0048] Furthermore, in a possible implementation, the nozzle module maintenance mechanism of the embodiment of the present application further includes a waste ink discharge pump, the fixing frame 100 is box-shaped, an opening is provided on one side wall of the fixing frame 100, the opening on the fixing frame 100 is arranged on the telescopic end side of the telescopic device 200, and the ink storage box 400 is fixedly mounted on the bottom inner wall of the fixing frame 100. The waste ink discharge pump is arranged on the side of the ink storage box away from the receiving box, the other end of the waste cleaning pipe is connected to the waste ink discharge pump, and the waste discharge pipe is arranged on the side of the ink storage box adjacent to the receiving box.

[0049] Here, it should be noted that the waste discharge pipe 500 is disposed adjacent to the bottom of the receiving box 300, so that the waste ink discharged from the nozzle can flow into the ink storage box 400 through the waste discharge pipe 500 in a timely manner, preventing excessive waste ink from accumulating in the receiving box 300, and allowing the waste ink in the ink storage box 400 to be discharged from the waste cleaning pipe 600 by using a waste ink discharge pump. Thus, the storage space for waste ink is further increased, making the storage space for waste ink approaching infinity, thereby further making the nozzle module maintenance mechanism of the embodiment of the present application more automated.

[0050] In another possible implementation, a through hole is opened on the side wall of the ink storage cartridge 400, and the through hole matches the waste removal tube 600. The other end of the waste removal tube 600 can pass through the through hole, thereby freely discharging the waste ink in the ink storage cartridge 400 by gravity.

[0051] Here, it should be noted that the waste discharge pipe 500 and the waste removal pipe 600 are both hoses, and both the waste discharge pipe 500 and the waste removal pipe 600 are arranged in an "L" shape. Here, it should also be noted that the waste discharge pipe 500 and the waste removal pipe 600 can also be an "L"-shaped hard pipe.

[0052] It should also be noted here that the fixing frame 100 is in the shape of an "L"-shaped box, and an "L"-shaped cavity matching the external shape of the fixing frame 100 is provided inside the fixing frame 100. And the volume of the bottom cavity of the fixing frame 100 is smaller than the volume of the top cavity of the fixing frame 100. It should be noted here that the top cavity of the fixing frame 100 is an installation cavity. It should also be noted here that the waste ink discharge pump can be fixed inside the installation cavity, and the waste ink discharge pump can also be fixed outside the installation cavity. It should also be noted here that a cutting edge is provided on the side of the fixing frame 100 away from the receiving box 300, and the cutting edge is located at the bottom of the side of the fixing frame 100 away from the receiving box 300. As a result, the structure of the fixing frame 100 is more matched with the structure of the printing device.

[0053] In one possible implementation, the telescopic device 200 includes a telescopic member 210 and a mounting frame 220. A through hole is provided on the top of the fixing frame 100. The mounting frame 220 is fixedly connected to the nozzle module mounting bracket 700 through the through hole. The telescopic member 210 is horizontally fixedly installed on the mounting frame 220, and the receiving box 300 is fixedly installed on the telescopic end of the telescopic member 210.

[0054] In a possible implementation, the telescopic member 210 is any one of a cylinder, a telescopic motor, a hydraulic cylinder or an electric push rod. Here, it should be noted that the mounting frame 220 includes a first mounting column 221 and a second mounting column 222, both of which are vertically fixed to the bottom of the nozzle module mounting bracket 700, and the first mounting column 221 and the second mounting column 222 are provided with a first mounting hole, and the second mounting column 222 is provided with a second mounting hole, the first mounting hole and the second mounting hole are coaxially arranged, and the telescopic member passes through the first mounting hole and the second mounting hole in sequence, so that the telescopic member 210 is fixed to the first mounting column 221 and the second mounting column 222.

[0055] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 or Fig.12 As shown, in a possible implementation, a sealing ring 310 is provided at the top opening of the receiving box 300, and the sealing ring 310 is arranged circumferentially along the top opening of the receiving box 300. Here, it should be pointed out that the sealing ring 310 is a buffer sealing rubber ring. Thus, it is possible to avoid accidental contact between the receiving box 300 and the bottom plate of the nozzle, which may cause damage to the telescopic parts or the nozzle module / alarm and other failures. In addition, because the nozzle needs to be in a surface moisturizing state for a long time, when the printer is in a shutdown state, the nozzle surface needs to be in a moisturizing external condition. The bottom plate of the nozzle module and the buffer sealing rubber ring on the receiving box 300 are in light contact, and the ink or moisturizing liquid remaining in the receiving box 300 can create a moist condition for the nozzle to moisturize.

[0056] Furthermore, in a possible implementation, a throttle valve or a stop valve is installed on the waste pipe 500, whereby the internal cavity of the receiving box 300 can be further sealed by closing the throttle valve or the stop valve, which can achieve a better moisturizing effect on the nozzle.

[0057] In a possible implementation, an active cleaning mechanism 320 and a negative pressure cleaning mechanism 330 are provided inside the cavity of the receiving box 300. Both the active cleaning mechanism 320 and the negative pressure cleaning mechanism 330 are arranged adjacent to the top opening of the receiving box 300. The active cleaning mechanism 320 is arranged adjacent to the telescopic device 200, and the negative pressure cleaning mechanism 330 is arranged away from the telescopic device 200. The active cleaning mechanism 320 and the negative pressure cleaning mechanism 330 are arranged inside the receiving box 300, and the active cleaning operation on the surface of the nozzle can be completed with the cooperation of the telescopic action of the telescopic device 200. That is, the telescopic device 200 pushes the receiving box 300 to the bottom of the nozzle module, and the active cleaning mechanism 320 sprays the nozzle cleaning liquid upward to make it adhere to the nozzle surface. When the telescopic device 200 retracts, the negative pressure cleaning mechanism 330 operates to recover the cleaning liquid on the nozzle surface. Here, it should be pointed out that the active cleaning mechanism 320 and the negative pressure cleaning mechanism 330 are both conventional technical means of relevant technical personnel in the field, and will not be repeated here. Here, it should also be pointed out that the top of the receiving box 300 is arranged adjacent to the nozzle module so that the receiving box 300 is almost in contact with the nozzle module when extended, thereby preventing ink from splashing, volatilizing, and causing external pollution during the nozzle cleaning operation.

[0058] Here, it should also be pointed out that the active cleaning mechanism 320 can also be arranged away from the telescopic device 200, and the negative pressure cleaning mechanism 330 can be arranged adjacent to the telescopic device 200. The above arrangement enables the telescopic device 200 to complete the cleaning operation of the nozzle during the extension process.

[0059] Based on any of the above-mentioned nozzle module maintenance mechanisms, the present disclosure also provides a printing device. Among them, the printing device of the embodiment of the present disclosure includes any of the above-mentioned nozzle module maintenance mechanisms. By installing any of the above-mentioned nozzle module maintenance mechanisms on the nozzle module mounting bracket 700 in the printing device, when performing nozzle maintenance and cleaning, the nozzle cleaning and maintenance time can be greatly reduced, the equipment production efficiency can be improved, and the fully automatic structure can get rid of human intervention and liberate labor.

[0060] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
