Description

Technical Field

[0001] This application relates to the technical field of printing machinery, and particularly to a printing device with a cleaning function. Background Art

[0002] Cardboard printing refers to the process of printing images or texts on cardboard (including corrugated cardboard and other types of cardboard). Cardboard is a material widely used in the packaging industry and is favored for its low cost, light weight, easy processing, and transportation.

[0003] There are several types of cardboard for printing media as follows.

[0004] Corrugated cardboard: It is composed of one or more layers of corrugated core paper (corrugations) sandwiched between two or more layers of face paper and is commonly used for making shipping packaging boxes.

[0005] Cardstock: A relatively thick cardboard, commonly used for making gift boxes, display stands, business cards, etc.

[0006] Kraft cardboard: It has a tough texture and is mostly used for making file folders, packaging boxes, etc.

[0007] These printing media are mainly used as packaging materials, and as the size of the printed medium increases, the size of the equipment also increases, and the requirements for its functions and the equipment are also higher.

[0008] Especially in inkjet printing, due to the possibility of ink clogging the nozzles or other impurities clogging the nozzles, there is a need for a nozzle cleaning function. Therefore, in the prior art, there have emerged devices or equipment that integrate printing and cleaning.

[0009] However, the printing equipment in the prior art is small, and the requirements for the size of the printing medium are also small, so the demand for cleaning is also small.

[0010] As the size of the printing medium increases, not only does the overall size of the printing device change, but its functions also need to adapt accordingly. It cannot be directly scaled up and used, but some components or mechanisms need to be adjusted adaptively. For example, in some prior art solutions, the component for supporting cleaning and discharging sewage is in an inclined pocket shape, which can be used for small devices, but when directly used on large devices, there will be a problem that the ink after cleaning splashes outside the supporting bracket. Therefore, the prior art has the problem of not being directly applicable to large-size printing media. Utility Model Content

[0052] Please refer to Figures 1 - 5, An exemplary printing device with a cleaning function according to the present application includes a conveying mechanism 20, a printing mechanism 10, a cleaning mechanism 30, and a support frame 40; the conveying mechanism 20 is installed on the support frame 40; the printing mechanism 10 is installed on the support frame 40 and is located above the conveying mechanism 20; the cleaning mechanism 30 is installed on one side of the conveying mechanism 20 through the support frame 40;

[0053] The cleaning mechanism 30 includes an adsorption component 31, a supporting component 32, and a sewage discharge component 33;

[0054] The adsorption component 31 is installed on the support frame 40 and is located on one side of the conveying mechanism 20;

[0055] The supporting component 32 is placed horizontally and is located on one side of the adsorption component 31. The length direction of the supporting component 32 is perpendicular to the conveying direction of the conveying mechanism 20;

[0056] The sewage discharge component 33 is installed at the bottom of the supporting component 32;

[0057] The printing mechanism 10 is slidably installed on the support frame 40 and is located above the adsorption component 31 and the supporting component 32;

[0058] The top surface of the supporting component 32 is lower than the top surface of the adsorption component 31.

[0059] In the present application, the cleaning mechanism 30 is used for cleaning the printing mechanism 10 and collecting sewage.

[0060] In the present application, the printing mechanism 10 is installed on the support frame 40, and the printing mechanism 10 can slide horizontally and can also be lifted on the support frame 40; the lifting and horizontal movement of the printing mechanism 10 are two independent actions, driven and completed separately by two sets of independent mechanisms. For the lifting and horizontal movement of the printing mechanism 10, this can be achieved by the prior art and will not be elaborated here.

[0061] In the present application, the conveying mechanism 20 is used for transporting printing media. It can be any one of the conveying mechanisms 20 in the prior art, which can have a negative pressure adsorption function or a function of pressing down the printing media and then conveying it to meet the printing requirements of the printing mechanism 10.

[0062] In some preferred embodiments, the supporting component 32 includes an inclined support plate 321 and a baffle 322;

[0063] The inclined support plate 321 is placed horizontally, and the two inclined support plates 321 are placed in a "V" shape, and a guiding space is formed above it;

[0064] The sewage discharge assembly 33 is installed at the bottom end of the inclined support plate 321 and communicates with the diversion space;

[0065] The two baffles 322 are respectively installed at the ends of the inclined support plate 321;

[0066] One end of the inclined support plate 321 is placed on one side of the adsorption assembly 31; the two inclined support plates 321 are respectively installed on the support frame 40.

[0067] It should be noted that the diversion space described in this application can be understood as a containing space or a storage space. It is used to guide the liquid droplets to gather and gather towards the sewage discharge assembly 33 for unified storage and discharge.

[0068] In this preferred embodiment, the two inclined support plates 321 form a diversion space to collect the liquid droplets dripped from the nozzles.

[0069] In some preferred embodiments, a plurality of the baffles 322 are respectively installed in the middle of the inclined support plate 321;

[0070] The shape of the baffle 322 is the same as the shape of the diversion space.

[0071] In this preferred embodiment, the baffle 322 is not only arranged at the ends of the inclined support plate 321, but also arranged in the middle of the inclined support plate 321. Thus, the baffle 322 also plays a role in strengthening the connection stability between the two inclined support plates 321. At the same time, the baffle 322 also plays a role in preventing the liquid droplets from overflowing, so it is arranged at the ends and the middle of the inclined support plate 321. Of course, the baffle 322 arranged in the middle of the inclined support plate 321 separates the liquid on both sides of it, so that the diversion space is separated into two spaces by one baffle 322 and into three spaces by two baffles 322.

[0072] In some preferred embodiments, the support assembly 32 further includes a bottom plate 323 and a top surface mounting plate 324;

[0073] The bottom plate 323 is installed at the bottom of the inclined support plate 321 and is located between the two inclined support plates 321;

[0074] The top surface mounting plate 324 is installed at the top of the inclined support plate 321, and the two top surface mounting plates 324 are respectively located on the sides of the two inclined support plates 321;

[0075] The sewage discharge assembly 33 is connected to the bottom plate 323 and penetrates through the bottom plate 323;

[0076] The support assembly 32 is connected to the support frame 40 through the top surface mounting plate 324.

[0077] In this preferred embodiment, setting the bottom plate 323 makes it more convenient to install the sewage discharge assembly 33. Setting the top surface mounting plate 324 has two functions. One is to facilitate the installation with the support frame 40, and the other is to strengthen the strength of the diagonal support plate 321 in the length direction.

[0078] In some preferred embodiments, the sewage discharge assembly 33 includes a sewage discharge pipe 331 and a collector 332;

[0079] A plurality of the sewage discharge pipes 331 are installed on the bottom plate 323, and the plurality of sewage discharge pipes 331 are respectively connected to the collector 332;

[0080] The collector 332 is used to collect the liquids of the plurality of sewage discharge pipes 331 and discharge them through a main pipe.

[0081] Since the diversion space is separated into multiple spaces by the baffle 322, at least one sewage discharge pipe 331 is correspondingly installed on the bottom plate 323 in each space; in some embodiments, a plurality of sewage discharge pipes 331 are installed on the bottom plate 323.

[0082] The collector 332 can be a multi-to-one adapter, which is an adapter for converging multiple branches into a single main pipe. By setting the collector 332, it is convenient to collect all the droplets and liquids.

[0083] In some preferred embodiments, the collector 332 is connected to a negative pressure system, and the sewage discharge is accelerated by means of negative pressure adsorption.

[0084] In some preferred embodiments, the supporting assembly 32 further includes a side fence 325, and the side fence 325 is installed outside the top surface mounting plate 324;

[0085] The side fence 325 is used to enclose the droplets in the diversion space and prevent them from overflowing or splashing.

[0086] The side fence 325 is provided to prevent the droplets dripping on the diagonal support plate 321 from splashing, and plays a good role in enclosing and collecting the droplets.

[0087] According to the above various embodiments, for different examples of the supporting assembly, in Figure 5 Three of the supporting assemblies are shown, and are shown in a side view for a clearer understanding of the differences between different embodiments.

[0088] In some preferred embodiments, the supporting assembly 32 further includes an adsorption cloth (not shown), and the adsorption cloth is laid above the diagonal supporting plate for preventing the splashing of droplets.

[0089] In some further embodiments, the adsorption cloth is made of materials such as flannelette, cotton cloth, linen cloth, plastic cloth, mesh cloth, sponge, etc. The adsorption cloth is provided to disperse the dripping liquid, so as to prevent the liquid droplets from directly dripping onto the inclined support plate 321, thereby playing a role in preventing splashing or splashing down.

[0090] In some preferred embodiments, the adsorption assembly 31 includes a plurality of negative pressure nozzles, and the plurality of negative pressure nozzles are installed on the support frame 40, and the negative pressure nozzles are connected to a negative pressure system.

[0091] The plurality of negative pressure nozzles are distributed in a strip shape, so that a column of printing nozzles can be subjected to negative pressure adsorption at the same time, and then the printing nozzles can be cleaned by negative pressure to dredge the printing nozzles.

[0092] In some preferred embodiments, a plurality of printing nozzles are provided on the bottom surface of the printing mechanism 10;

[0093] The negative pressure nozzle is used to adsorb the printing nozzle;

[0094] The total length of the plurality of negative pressure nozzles is greater than the total width of the printing nozzles on the printing mechanism 10; the width of the supporting assembly 32 is greater than the total width of the printing nozzles on the printing mechanism 10;

[0095] The length of the supporting assembly 32 is greater than the total length of the printing nozzles on the printing mechanism 10.

[0096] A plurality of printing nozzles are installed at the bottom of the printing mechanism 10 in a multi-row and multi-column form. Therefore, the printing nozzles on the entire printing mechanism 10 form a rectangular distribution state. The width of this rectangle is less than the total length of the negative pressure nozzles, so that the adsorption cleaning of a column of printing nozzles can be completed at one time; the length of this rectangle is less than the length of the supporting assembly 32, so that the printing mechanism 10 can be statically placed above the inclined support plate 321, thereby providing sufficient time for the liquid droplets on the printing nozzle to drip.

[0097] In some preferred embodiments, the printing mechanism 10 is inkjet printing or UV printing;

[0098] The conveying mechanism 20 is used for conveying cardboard, paper, panel, wood board, stone slab.

[0099] Compared with the inclined cleaning mechanism 30 in the prior art, the technical solution of the present application is more applicable to large equipment.

[0100] The printing device with a cleaning function according to the present application, firstly, provides a cleaning function for the detachable cleaning of the printing nozzle, ensuring the good use effect of the printing mechanism 10 and the convenient cleaning effect. Secondly, a horizontally arranged cleaning mechanism 30 is provided, effectively preventing the splashing of liquid drops when dripping, so it has good adaptability for large printing devices; finally, due to the setting of the adsorption cloth, the anti-dripping and anti-splashing effects of liquid drops are better, and it is also more suitable for large devices.

[0101] In the printing device with a cleaning function according to the present application, the nozzles of the printing mechanism 10 are sequentially subjected to negative pressure adsorption by the adsorption assembly 31, then the nozzles are dredged or the ink is sucked out, and then the printing mechanism 10 continues to move horizontally above the supporting assembly 32, and the ink in the nozzles drops on the supporting assembly 32 and is received by the supporting assembly 32, and finally discharged from the sewage discharge assembly 33. During this whole process, the ink is sucked out and the nozzles are unblocked, and the cleaning of the nozzles is also realized. The ink is received through the supporting assembly 32, ensuring the cleanliness of the site and the surrounding environment. Compared with the prior art, the supporting assembly 32 of the present application is horizontally placed and located on one side of the adsorption assembly 31, and has a better anti-splashing effect on the dripping liquid drops, so it is more suitable for large printing devices.

[0102] The above embodiments only represent several implementation manners of the present application, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
