DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0034] See also Figure 1-Figure 2The embodiment of the utility model provides a nozzle maintenance structure, including a bottom plate 10, a suction assembly 20, an ink scraping assembly 30 and a moisturizing box 40. The suction assembly 20 is arranged on the bottom plate 10, and the suction assembly 20 includes a suction nozzle 201, which is used to suck away the ink and / or dust on the nozzle. The ink scraping assembly 30 can be movably arranged on the bottom plate 10 and is located on one side of the suction assembly 20. The ink scraping assembly 30 includes a scraper 301, which can scrape away the ink and / or dust on the nozzle. At least the upper end of the scraper 301 is made of flexible material, which can avoid damaging the nozzle when the scraper contacts the nozzle. At the same time, the upper end made of flexible material can be squeezed and bent when contacting the nozzle, which can increase the contact area between the scraper 301 and the nozzle surface, and further improve the cleaning effect. The moisturizing box 40 is arranged on the bottom plate 10 and is located on the side of the ink scraping assembly 30 away from the suction assembly 20. The moisturizing box 40 is used to moisturize the nozzle.

[0035] By setting the suction component 20, the ink or dust on the nozzle can be sucked, the ink scraping component 30 can be set to scrape off the stubborn ink or dust on the nozzle, and the moisturizing box 40 can be set to moisturize the nozzle that is not working. By integrating the suction component 20, the ink scraping component 30 and the moisturizing box 40 on the bottom plate 10, the structure can be compact and space-saving. Compared with the independent setting method, the space occupation can be reduced in a limited space. The ink scraping component 30 is movably set on the bottom plate 10, and the ink scraping component 30 can be moved up and down to be away from the bottom plate 10. Open the working position or return to the working position, that is, the nozzle maintenance structure can select the suction component 20 and / or the ink scraping component 30 to clean the nozzle according to the cleaning needs of the nozzle. When the suction component 20 is used alone to clean the nozzle, the ink scraping component 30 can be controlled to move away from the working position. When the ink scraping component 30 is used alone to clean the nozzle, the air source of the suction component 20 can be turned off. The suction component 20 and the ink scraping component 30 can also be used together to clean the nozzle to improve the cleaning effect. The cleaning function is diversified, can adapt to different nozzle cleaning, and also has a moisturizing function.

[0036] The nozzle cleaning and maintenance device provided by the utility model has an integrated structural setting, which makes the structure compact, can reduce the space occupied, improve the space utilization rate, and can also meet the cleaning and moisturizing of the nozzle at the same time. The cleaning methods are diversified, which can meet different cleaning needs and improve the cleaning effect and maintenance work efficiency.

[0037] See also Figure 3-Figure 6When starting work, the printing unit 100 moves to the cleaning work area, the nozzle maintenance structure moves to the cleaning preparation work area, the printing unit 100 moves downward to the top of the suction assembly 20, so that the distance between the nozzle of the printing unit 100 and the suction port 2011 is within the adsorption range of the suction port 2011, the suction assembly 20 is started and the suction port 2011 continues to generate suction, the nozzle maintenance structure continues to move along the current direction, and the ink and / or dust on the nozzle are sucked away while the suction port 2011 passes through the nozzle. The scraper 301 of the ink scraping assembly 30 can perform a secondary cleaning on the cleaned nozzle to scrape off the residual dried ink and / or dust on the nozzle. Finally, the moisturizing box 40 moves to the bottom of the printing unit 100, and the nozzle enters the moisturizing box. 40 for moisturizing; if the current nozzle does not need to be cleaned by adsorption, the suction component 20 can be closed to put the suction component 20 in a shutdown state until the nozzle cleaning and maintenance device moves to make the scraper component 30 located below the printing unit 100, and the nozzle is cleaned by the scraper 301; if the current nozzle cannot be used or does not need to be cleaned by the scraper 301, the scraper component 30 can be moved downward to leave the working position, and the suction component 20 cleans the nozzle and then the moisturizing box 40 moisturizes the nozzle; if the current nozzle does not need to be cleaned, the suction component 20 can be closed and the scraper component 30 can be moved downward to leave the working position, and the moisturizing box 40 can be directly moved to the bottom of the nozzle, and the nozzle enters the moisturizing box 40 for moisturizing after it drops a preset distance. This design solution only requires one unidirectional movement of the nozzle maintenance structure to achieve one or two cleaning and moisturizing of the nozzle, and the maintenance work efficiency is high.

[0038] See also Figure 2 Specifically, the base plate 10 is provided with a first mounting groove 101 for mounting the suction assembly 20, a second mounting groove 102 for mounting the ink scraping assembly 30, and a third mounting groove 103 for mounting the moisturizing box 40. The first mounting groove 101, the second mounting groove 102 and the third mounting groove 103 are arranged in sequence along the movement direction of the nozzle maintenance structure.

[0039] See also Figure 7-Figure 8Furthermore, the suction assembly 20 also includes a box body 202 and a roller 203. The box body 202 is arranged on the bottom plate 10. A negative pressure air chamber is arranged inside the box body 202. The negative pressure air chamber is provided with an air outlet 2021. The air outlet 2021 is used to communicate with the negative pressure source 60. The suction nozzle 201 is arranged above the box body 202 and communicates with the negative pressure air chamber. The roller 203 is arranged on the box body 202 and is located on opposite sides of the suction nozzle 201. The surface of the roller 203 protrudes from the suction port 2011 of the suction nozzle 201. After the air outlet 2021 is connected to the negative pressure source 60, the negative pressure source 60 is turned on to form a negative pressure at the suction port 2011, so that the ink and / or dust on the nozzle can be sucked away. The roller 203 is provided and protrudes from the suction port 2011. After the nozzle cleaning and maintenance device moves to the bottom of the nozzle and the nozzle is lowered, the roller 203 can abut against the surface of the nozzle to position the suction port 2011. At the same time, during the movement of the nozzle maintenance structure, the roller 203 rolls and rubs between the nozzles to avoid scratching the nozzle. Specifically, the distance between the upper surface of the roller 203 and the suction port 2011 is 0.2 mm to avoid the suction force at the suction port 2011 being affected by the large distance, thereby affecting the adsorption effect.

[0040] See also Figure 8 Specifically, a through hole 202b is provided on the side wall of the box body 202, and the through hole 202b is connected to the negative pressure air cavity. An adapter 70 is provided on the through hole 202b, and an air outlet 2021 is provided on the adapter 70. A connecting groove 202a is also provided on the top of the box body 202. The suction nozzle 201 is arranged on the top of the box body 202 and is connected to the negative pressure air cavity through the connecting groove 202a. The negative pressure source 60 is connected to the air outlet 2021 by a connecting pipe 50. The connecting pipe 50 can be a corrugated pipe, and the negative pressure source 60 can be a vacuum cleaner.

[0041] See also Figure 7-Figure 8 Furthermore, the suction assembly 20 also includes a first fixing seat 204 and a first elastic member 205 fixed on the bottom plate 10. The box body 202 is arranged on the first fixing seat 204 so as to be movable up and down. The first elastic member 205 is arranged on the first fixing seat 204 and provides a pre-tightening force for the box body 202 to move in the direction of the suction port 2011 of the suction nozzle 201. In this way, when the nozzle and the roller 203 are in contact, the hard contact between the two can be converted into a soft contact, so as to avoid the roller 203 damaging the nozzle due to excessive downward travel of the printing unit 100. At the same time, the reaction force of the first elastic member 205 after being compressed can provide the box body 202 with a force to move toward the nozzle, so that the suction port 2011 and the nozzle can be kept at a constant distance, thereby ensuring the adsorption effect.

[0042] See also Figure 8Further, the box body 202 is provided with a first connecting portion 2022 outside, the first fixing seat 204 is provided with a mounting position 2051, the first connecting portion 2022 is placed in the mounting position 2051 and can move up and down in the mounting position 2051, and the first elastic member 205 is provided between the mounting position 2051 and the first connecting portion 2022. In this way, through the cooperation between the first connecting portion 2022 and the mounting position 2051, the movable installation of the box body 202 on the first fixing seat 204 can be realized, and the first elastic member 205 can provide a pre-tightening force to the connecting portion so that the box body 202 is always kept in a preset position. Specifically, the mounting position 2051 can be a U-shaped groove, so that the connecting portion can be installed from the opening 401 of the U-shaped groove to improve the installation efficiency.

[0043] See also Figure 9-11 Furthermore, the ink scraping assembly 30 also includes a base 302 that can be moved up and down on the bottom plate 10, and the scraper 301 is arranged on the base 302, so that the bottom plate 10 that moves up and down can drive the entire ink scraping assembly 30 to move up and down.

The second elastic member 304 is provided on the base 302 and provides a pre-tightening force to the mounting seat 303 to move toward the upper end of the scraper 301. By setting a mounting seat 303 that can move up and down relative to the base 302 and using the second elastic member 304 to provide a pre-tightening force for the mounting seat 303 away from the base 302, and then fixing the scraper 301 on the mounting seat 303, when the scraper 301 contacts the nozzle to clean the nozzle, the second elastic member 304 can create a buffering effect when the scraper 301 contacts the nozzle, avoiding direct hard contact between the scraper 301 and the nozzle, thereby causing damage to the nozzle. At the same time, the restoring force of the second elastic member 304 after being squeezed by the nozzle can provide the scraper 301 with a force to resist the nozzle, thereby ensuring that the scraper 301 is in good contact with the nozzle, thereby improving the cleaning effect.

[0045] See also Figure 9-11 Furthermore, the ink scraping assembly 30 also includes a driving member 307 for driving the base 302 to move up and down, and a first fixed seat 308.

The driving end of the driving member 307 is connected to the base 302 to drive the base 302 to move up and down. The driving member 307 drives the base 302 to move up and down, which can drive the ink scraping assembly 30 to move up and down as a whole, and then the scraper can be lifted to the working position or withdrawn from the working position according to the needs, so that it can be operated according to the cleaning needs of different nozzles to decide whether to use the ink scraping assembly 30 for cleaning, thereby improving the cleaning flexibility for different nozzles of different equipment.

[0046] See also Figure 9-10 Furthermore, the ink scraper assembly 30 also includes a connecting member 305, which passes through the mounting seat 303 and the base 302 in sequence and is connected to the base 302 to prevent the mounting seat 303 from being separated from the base 302. The mounting seat 303 can move relative to the connecting member 305 to prevent the connecting member 305 from interfering with the up and down movement of the mounting seat 303. At the same time, the connecting member 305 can also guide the movement of the mounting seat 303.

[0047] See also Fig.10 Furthermore, the connecting member 305 includes a second connecting portion 3051 that passes through the mounting seat 303 and the base 302, and a limiting portion 3052 connected to the second connecting portion 3051. The mounting seat 303 can move relative to the second connecting portion 3051. Under the action of the second elastic member 304, the limiting portion 3052 can abut against the mounting seat 303, and the limiting portion 3052 can prevent the mounting seat 303 from separating from the base 302.

[0048] See also Fig.10 Specifically, the mounting seat 303 is provided with a hole 3021 through which the second connecting portion 3051 can pass, and the inner diameter of the hole 3021 is larger than the second connecting portion 3051 so that the mounting seat 303 can move up and down relative to the second connecting portion 3051.

[0050] See also Fig.11 Furthermore, the scraper blade 301 is fixedly mounted on the outside of the mounting seat 303. Compared with the scraper blade 301 being arranged inside the mounting seat 303, the scraper blade 301 being arranged on the outside of the mounting seat 303 can reduce the complexity of processing the scraper blade 301 mounting structure of the mounting seat 303 and improve production efficiency.

[0051] See also Fig.11 Furthermore, a support portion 3031 is provided on the outer side of the mounting seat 303, and the bottom of the scraper blade 301 abuts against the support portion 3031. The support portion 3031 can support the scraper blade 301, and can prevent the scraper blade 301 from moving toward the base 302 (i.e., away from the upper end of the scraper blade 301) after long-term use, thereby causing poor contact between the scraper blade 301 and the nozzle.

[0052] See also Figure 10-11 Furthermore, the ink scraper assembly 30 also includes a scraper blade 301 pressure plate, which is attached to the side of the scraper blade 301 away from the mounting seat 303 and is connected and fixed to the mounting seat 303.

[0054] Furthermore, a moisturizing block (not shown) is provided in the moisturizing box 40, and the moisturizing block is made of a water-absorbing material, so that water can be added to the moisturizing block to increase the humidity of the air in the moisturizing box 40, thereby further improving the moisturizing effect.

[0055] See also Fig.12 The embodiment of the utility model also provides a nozzle maintenance platform, including a fixed platform 200 and the above-mentioned nozzle maintenance structure 300. The number of nozzle maintenance structures 300 is several, and the several nozzle maintenance structures 300 are arranged in parallel and at intervals on the fixed platform 200, so that multiple columns of nozzles can be cleaned and moisturized at the same time, thereby improving the cleaning efficiency.

[0056] The nozzle maintenance platform provided by the embodiment of the utility model has an integrated structural setting, which makes the structure compact, can reduce the space occupied, improve the space utilization rate, and can also meet the cleaning and moisturizing of the nozzle at the same time, and the cleaning methods are diversified, which can improve the cleaning effect and the cleaning efficiency.
