Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, and particularly relates to an inkjet device for printing equipment. Background Technique

[0002] Printing is a technology that transfers the original manuscripts such as words, pictures, photos, anti-counterfeiting, etc. to the surfaces of materials such as paper, textiles, plastics, leather, PVC, PC, etc. through processes such as plate making, ink application, and pressure application, and batch-replicates the content of the original manuscripts. Printing is the process of transferring the approved printing plate to the printing substrate through printing machinery and special ink.

[0003] When the existing inkjet device for printing is in use, its principle is that a number of small nozzles are opened at the bottom of the inkjet device. The nozzles are designed with a wider upper part and a narrower lower part, which will form a negative pressure to prevent ink leakage. During printing, the heating resistor above will heat the temperature to 100 degrees in a very short time, evaporate the nearby ink at high temperature, and form bubbles. The bubbles act as pistons to push out the ink below, thereby realizing the printing work. However, in the actual use process of the nozzles, the ink often solidifies and clogs due to long-term non-use. The existing cleaning method is to print for a period of time in advance to flush out the solidified ink, but this cleaning method has limited effect. Once the solidified ink is not flushed out, it may cause the clogging to worsen. Therefore, an inkjet device for printing equipment is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an inkjet device for printing equipment to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] As an optional scheme of an inkjet device for printing equipment described in the utility model, wherein: an inkjet device for printing equipment includes a printing equipment and an inkjet device.

[0007] An inkjet device is installed on one side of the printing equipment. A placement platform fixedly connected to the printing equipment is arranged below the inkjet device, and a cleaning component is installed on one side above the placement platform. A control cabinet fixedly connected to the printing equipment is arranged on one side of the placement platform.

[0008] The cleaning component includes a fixed frame, a moving plate, and a blanking hole. The bottom of the fixed frame is fixedly connected to the placement platform. A cylinder is fixedly connected to the center inside the fixed frame, and an adsorption plate is fixedly connected to the free end of the cylinder. A moving plate is arranged above the adsorption plate, and a longitudinal plate and a transverse plate arranged in a cross manner are installed above the moving plate.

[0009] Both sides of the bottom of the movable plate are fixedly connected with lifting mechanisms. The outer sides of the lifting mechanisms are fixedly connected with the fixed frame, and the outer sides of the lifting mechanisms are slidably connected with the adsorption plate.

[0010] As an alternative solution of the inkjet device for a printing device according to the present invention, wherein: sealing plates are installed on the tops of the longitudinal plate and the transverse plate.

[0011] As an alternative solution of the inkjet device for a printing device according to the present invention, wherein: uniformly distributed blanking holes are formed on the surface of the movable plate.

[0012] As an alternative solution of the inkjet device for a printing device according to the present invention, wherein: notches are formed on both sides of the adsorption plate, and the adsorption plate is slidably connected with the lifting mechanism through the notches, and both sides of the adsorption plate are in close contact with the lifting mechanism.

[0013] As an alternative solution of the inkjet device for a printing device according to the present invention, wherein: the outer side of the adsorption plate is convex and horizontally arranged in the center.

[0014] When the existing inkjet device for printing is in use, its principle is that a number of small nozzles are opened at the bottom of the inkjet device. The nozzles are designed to be wider at the top and narrower at the bottom, which will form a negative pressure to prevent ink leakage. During printing, the heating resistor above will heat the temperature to 100 degrees in a very short time, evaporate the nearby ink at high temperature, and form bubbles, which will act as a piston to push out the ink below, thereby realizing the printing work. However, in the actual use process of the nozzles, the problem of ink solidification and blockage often occurs due to long-term non-use. The existing cleaning method is to print for a period of time in advance to flush out the solidified ink, but this cleaning method has limited effect. Once the solidified ink is not flushed out, it may cause the blockage to intensify. When this device is in use and is externally powered, once the nozzle is blocked, at this time, the inkjet device is moved above the cleaning component, and the lifting mechanism drives the movable plate to move upward, and at the same time, the longitudinal plate and the transverse plate above the movable plate move upward. At this time, the sealing plate is in close contact with the lower end surface of the inkjet device. Then, the air cylinder is quickly started to drive the adsorption plate to move downward. At this time, under the action of the negative pressure, the blocked ink impurities of the inkjet device can be pumped out to achieve the purpose of cleaning. The pumped ink can enter above the adsorption plate through the blanking holes, and the adsorption plate is convexly arranged around, which helps to centrally collect the ink materials and facilitate the subsequent cleaning work.

[0015] As an alternative solution for an inkjet device used in a printing apparatus of the present utility model, wherein: the lifting mechanism includes a mounting frame, a motor, and a threaded shaft. The outer side of the mounting frame is fixedly connected to the fixed frame. A motor is fixedly connected inside the mounting frame. The end of the main shaft of the motor is fixedly connected to the threaded shaft. A lifting sleeve is spirally connected to the outer side of the threaded shaft. The outer side of the lifting sleeve is slidably connected to the adsorption plate.

[0016] As an alternative solution for an inkjet device used in a printing apparatus of the present utility model, wherein: a guide plate is further fixedly connected to the outer side of the lifting sleeve. The outer side of the guide plate is slidably connected to the mounting frame.

[0017] When the moving plate moves, the motor drives the threaded shaft to rotate, thereby causing the lifting sleeve to move, facilitating the lifting of the moving plate. And the setting of the guide plate facilitates the stable movement of the lifting sleeve. At the same time, the outer side of the guide plate is slidably connected and sealed with the fixed frame, which helps to form a chamber between the moving plate and the adsorption plate, facilitating the rapid movement of the adsorption plate for cleaning work.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] When the present utility model is in use, once the nozzle is blocked, at this time, the inkjet device is moved above the cleaning component, and the lifting mechanism drives the moving plate to move upward. At the same time, the longitudinal plate and the transverse plate above the moving plate move upward. At this time, the sealing plate is in close contact with the lower end surface of the inkjet device. Then, the air cylinder is quickly started to drive the adsorption plate to move downward. At this time, under the action of negative pressure, the blocked ink impurities in the inkjet device can be pumped out to achieve the purpose of cleaning;

[0020] The pumped ink can enter above the adsorption plate through the material discharge hole. And the adsorption plate is provided with protrusions around it, which helps to centrally collect the ink material and facilitate subsequent cleaning work;

[0021] When the moving plate moves, the motor drives the threaded shaft to rotate, thereby causing the lifting sleeve to move, facilitating the lifting of the moving plate. And the setting of the guide plate facilitates the stable movement of the lifting sleeve. At the same time, the outer side of the guide plate is slidably connected and sealed with the fixed frame, which helps to form a chamber between the moving plate and the adsorption plate, facilitating the rapid movement of the adsorption plate for cleaning work.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1

[0028] Please refer to Figure 1 and Figure 2 , the present invention provides a technical solution:

[0029] An inkjet device for a printing device, including a printing device 1 and an inkjet device 2,

[0030] An inkjet device 2 is installed on one side of the above-mentioned printing device 1, a placement platform 3 fixedly connected to the printing device 1 is arranged below the above-mentioned inkjet device 2, and a cleaning component 5 is installed on one side above the placement platform 3, and a control cabinet 4 fixedly connected to the printing device 1 is arranged on one side of the placement platform 3;

[0031] The above-mentioned cleaning component 5 includes a fixed frame 501, a moving plate 502 and a feeding hole 503. The bottom of the fixed frame 501 is fixedly connected to the placement platform 3. A cylinder 508 is fixedly connected to the center inside the fixed frame 501, and an adsorption plate 507 is fixedly connected to the free end of the cylinder 508. A moving plate 502 is arranged above the adsorption plate 507, and longitudinal plates 504 and transverse plates 509 arranged in a cross shape are installed above the moving plate 502;

[0032] Both sides of the bottom of the above-mentioned moving plate 502 are fixedly connected with a lifting mechanism 506. The outside of the lifting mechanism 506 is fixedly connected to the fixed frame 501, and the outside of the lifting mechanism 506 is slidably connected to the adsorption plate 507.

[0033] Sealing plates 505 are installed on the tops of the above-mentioned longitudinal plates 504 and transverse plates 509.

[0034] The surface of the above-mentioned moving plate 502 is provided with evenly distributed material discharging holes 503.

[0035] Both sides of the above-mentioned adsorption plate 507 are provided with notches, and the adsorption plate 507 is slidably connected to the lifting mechanism 506 through the notches, and both sides of the above-mentioned adsorption plate 507 are in close contact with the lifting mechanism 506.

[0036] The above-mentioned adsorption plate 507 is arranged in a shape with a convex outer side and a horizontal center.

[0037] When the existing inkjet device for printing is in use, its principle is that a number of fine nozzles are provided at the bottom of the inkjet device. The nozzles are designed to be wider at the top and narrower at the bottom, which will form a negative pressure to prevent ink leakage. During printing, the heating resistor above will heat the temperature to 100 degrees in a very short time, evaporate the nearby ink at high temperature, and form bubbles, which will act as a piston to push out the ink below, thereby realizing the printing work. However, in the actual use process of the nozzles, the ink often solidifies and blocks due to long-term non-use. The existing cleaning method is to pre-print for a period of time to flush out the solidified ink. However, this cleaning method has limited effect. Once the solidified ink is not flushed out, it may cause the blockage to intensify at this time. When this device is in use, it is externally powered. Once the nozzle is blocked, at this time, the inkjet device 2 is moved above the cleaning component 5, and the lifting mechanism 506 drives the moving plate 502 to move upward. At the same time, the longitudinal plate 504 and the transverse plate 509 above the moving plate 502 move upward. At this time, the sealing plate 505 is in close contact with the lower end surface of the inkjet device 2. Then, the air cylinder 508 is quickly started to drive the adsorption plate 507 to move downward. At this time, under the action of negative pressure, the blocked ink impurities of the inkjet device 2 can be pumped out to achieve the purpose of cleaning. The pumped ink can enter above the adsorption plate 507 through the material discharging holes 503. And the adsorption plate 507 is provided with raised edges around, which helps to concentrate and collect the ink material, facilitating the subsequent cleaning work;

[0038] In this embodiment, the longitudinal plate 504 and the transverse plate 509 cooperate to form small areas, ensuring that during the subsequent negative pressure extraction and cleaning work, the spray holes are cleaned in a targeted manner. The longitudinal plate 504, the transverse plate 509 and the sealing plate 505 above this device will block a part of the ink spray holes. However, more than 95% of the nozzles will be cleaned when this device is cleaning;

[0039] The setting of the material discharging holes 503 can not only ensure the cleaning purpose under the action of negative pressure, but also ensure that the ink drops and is collected on the surface of the adsorption plate 507 through the material discharging holes 503. The adsorption plate 507 is high around and low in the center, which can effectively collect the ink and perform subsequent processing. The outer side of the adsorption plate 507 is in close contact with the fixed frame 501, which helps to perform the subsequent negative pressure cleaning work;

[0040] The printing device 1, the inkjet device 2, and the control cabinet 4 are existing technical products in the field. Therefore, their internal structures and principles will not be elaborated too much here.

[0041] Embodiment 2

[0042] This embodiment is an improvement on Embodiment 1. Please refer to Figure 3 , specifically, the lifting mechanism 506 includes a mounting frame 5061, a motor 5062, and a threaded shaft 5063. The outside of the mounting frame 5061 is fixedly connected to the fixed frame 501. A motor 5062 is fixedly connected inside the mounting frame 5061. The end of the main shaft of the motor 5062 is fixedly connected to the threaded shaft 5063. A lifting sleeve 5064 is spirally connected to the outside of the threaded shaft 5063. The outside of the lifting sleeve 5064 is slidably connected to the adsorption plate 507.

[0043] A guide plate 5065 is also fixedly connected to the outside of the lifting sleeve 5064. The outside of the guide plate 5065 is slidably connected to the mounting frame 5061.

[0044] When the moving plate 502 moves, the motor 5062 drives the threaded shaft 5063 to rotate, so that the lifting sleeve 5064 moves, facilitating the lifting of the moving plate 502. The setting of the guide plate 5065 facilitates the stable movement of the lifting sleeve 5064. At the same time, the outside of the guide plate 5065 is slidably connected to and sealed with the fixed frame 501, which helps to form a chamber between the moving plate 502 and the adsorption plate 507, facilitating the rapid movement of the adsorption plate 507 for cleaning work;

[0045] In this embodiment, the width of the guide plate 5065 is the same as the outer diameter of the lifting sleeve 5064. At this time, it can ensure a certain sealing environment in cooperation with the adsorption plate 507, which helps the subsequent negative pressure cleaning work.

[0046] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
