Description

Technical Field

[0001] This application relates to the field of printers, and particularly to an ink scraping device and a printer. Background Art

[0002] Today, with the rapid development of inkjet printing technology, especially in the industrial inkjet printing field, the performance and maintenance efficiency of the print head are directly related to the printing quality and production efficiency. During the operation of traditional industrial inkjet printers, when the print head performs the ink pressing action to ensure smooth inkjet, a large amount of ink often remains on its surface. If these residual inks are not removed in a timely and effective manner, it will not only cause the print head to clog, affect the inkjet accuracy, and thus affect the overall printing effect, but also increase the complexity and cost of equipment maintenance.

[0003] For a long time, the solution to this problem mainly relies on manual wiping. Although this method can remove some residual inks to a certain extent, it has many drawbacks: First, direct contact between the human hand and the ink is likely to cause hand contamination, which is not conducive to the health of the staff and the hygiene of the working environment; Second, during the wiping process, the rag needs to be frequently replaced or cleaned, resulting in waste of resources; Third, manual operation not only takes a long time and is inefficient, but also affected by human factors, it is difficult to ensure the wiping effect, and there may be an incomplete wiping situation, thus affecting subsequent printing operations; Finally, frequent wiping operations may also cause unnecessary physical wear to the print head and shorten its service life.

[0040] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0041] In this application, unless otherwise clearly defined and limited, terms such as "installed", "connected", "linked", "fixed", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components.

[0042] In this application, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature is at a higher horizontal level than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature is at a lower horizontal level than the second feature.

[0043] After an inkjet printer finishes printing, ink will remain at the inkjet position. If the ink at this position is not removed in time, it will clog the inkjet nozzle, affecting the inkjet printing accuracy and effect. The existing cleaning method is usually manual wiping of the inkjet nozzle with a rag. However, manual cleaning requires repeated washing of the wiped rag, resulting in waste of resources. Moreover, the manual cleaning efficiency is low and the cleaning effect is different each time, thus affecting the subsequent printing quality. Therefore, in this application, a two-axis moving module drives a deinking member 400 to move in a first preset direction and a second preset direction to automatically wipe the inkjet position, improving the wiping efficiency and quality.

[0044] A scraping device provided in this application includes a first linear driving module 100, a second linear driving module 200, a driven member 300, and at least one deinking member 400. The second linear driving module 200 is fixedly installed on the moving end of the first linear driving module 100. The first linear driving module 100 drives the second linear driving module 200 to move in a first preset direction. The driven member 300 is fixedly installed on the moving end of the second linear driving module 200. The second linear driving module 200 drives the driven member 300 to move in a second preset direction. The deinking member 400 is detachably installed on the driven member 300, and the deinking member 400 moves following the driven member 300.

[0045] Refer to Figure 1As shown, the two-axis moving module is composed of a first linear driving module 100 and a second linear driving module 200. In the above, the first preset direction is the up-and-down direction, and the second preset direction is the left-and-right direction. Specifically, the first linear driving module 100 can move up and down, and the second linear driving module 200 can move left and right. Therefore, the linkage combination of the first linear driving module 100 and the second linear driving module 200 can drive the ink removing member 400 on the driven member 300 to move in two directions, up and down and left and right. Furthermore, the ink removing member 400 can be moved to the position of the ink jet port and the ink removing member 400 is driven to wipe the ink jet port. After the wiping is completed, the first linear driving module 100 and the second linear driving module 200 are linked to drive the driven member 300 and the ink removing member 400 to return to the initial position. During the whole movement and wiping process, no manual participation is required, reducing the dependence on labor, improving efficiency and ensuring the wiping effect.

[0046] In this embodiment, the ink removing member 400 is plate-shaped and can be made of EPDM (Ethylene Propylene Diene Monomer - ethylene propylene rubber). In other embodiments, the ink removing member 400 can also be made of other materials or in other shapes, which are not specifically limited here. Further, the number and position of the ink removing members 400 can be adaptively set according to the number and position of the nozzles 900, and the specific number and position of the ink removing members 400 are not limited.

[0047] In this embodiment, refer to Figure 5 As shown, Figure 5 is a schematic diagram of the state where the device has not been wiped. Figure 6 is a schematic diagram of the state where the device is being wiped.

[0048] The first linear driving module 100 includes a bottom plate 110 and a fixing plate 120. The fixing plate 120 is fixedly installed on the bottom plate 110. At least one first lead screw 130 is rotatably installed on the bottom plate 110. A first moving member 150 is drivingly connected to the first lead screw 130. A first rotary driving member 140 is fixedly installed on the fixing plate 120. The first rotary driving member 140 is drivingly connected to the first lead screw 130. The first rotary driving member 140 drives the first lead screw 130 to rotate so that the first moving member 150 moves along the first preset direction.

[0049] Refer to Figures 2 to 4As shown, in order to achieve vertical lifting movement, the fixed plate 120 is installed on the bottom plate 110, and there is a certain gap between the fixed plate 120 and the bottom plate 110. Further, a plurality of first lead screws 130 are rotatably installed on the fixed plate 120. In this embodiment, there are four first lead screws 130, which are respectively arranged at the four corners of the fixed plate 120. The end of each first lead screw 130 is also rotatably connected to the bottom plate 110. For details, reference can be made to Figure 2 and Figure 3 shown; in order to enable the first moving member 150 to lift, the first moving member 150 is drivingly connected to each first lead screw 130. Specifically, a lead screw nut is used as the driving member, and the first rotary driving member 140 provides power for the rotation of each first lead screw 130. The first rotary driving member 140 is drivingly connected to each first lead screw 130, so as to drive the synchronous rotation between each first lead screw 130.

[0050] In this embodiment, the bottom plate 110, the fixed plate 120 and the first moving member 150 are all plate-shaped. The first moving member 150 is mainly used for the installation of the second linear driving module 200; the first rotary driving member 140 is a motor. Further, the first rotary driving member 140 is a servo motor. A belt pulley is installed at the rotating end of the first rotary driving member 140, and a synchronous belt pulley is also installed on each first lead screw 130. The synchronous belt pulleys are connected by a synchronous belt to achieve transmission.

[0051] The second linear driving module 200 includes a second rotary driving member 210. A second lead screw 220 is installed at the rotating end of the second rotary driving member 210. A second moving member 230 is drivingly connected to the second lead screw 220. The second rotary driving member 210 drives the second lead screw 220 to rotate so that the second moving member 230 moves along a second preset direction.

[0052] Reference is made to Figures 2 to 4 shown, the second linear driving module 200 is installed on the first moving member 150 mainly to achieve left-right movement. The second moving member 230 is slidably arranged on the first moving member 150. Specifically, two fixed seats are installed on the first moving member 150, and guide posts are arranged between the fixed seats. The second moving member 230 is slidably arranged on the guide posts, and the guide posts realize the movement guiding of the second moving member 230. Further, the second rotary driving member 210 is installed on one of the fixed seats. The second lead screw 220 is drivingly connected to the second moving member 230. The second lead screw 220 can convert the rotational power from the second rotary driving member 210 into the power for the left-right movement of the second moving member 230. In this embodiment, the second rotary driving member 210 drives the second lead screw 220 to rotate, so that the second moving member 230 moves left and right, and further drives the driven member 300 to also move left and right.

[0053] The follower 300 includes a follower plate 310, the ink removing member 400 is detachably mounted on the follower plate 310, a mounting plate 320 is fixedly mounted on the outer peripheral circle of the follower plate 310, a collecting groove 330 is defined between the follower plate 310 and the mounting plate 320, and the ink removing member 400 is located in the collecting groove 330.

[0054] Continue to refer to Figures 2 to 4 As shown, after the ink removing member 400 cleans the ink, in order to prevent the cleaned ink from flowing everywhere, the present application collects the cleaned ink through the collecting groove 330 formed by the enclosure and definition of the follower plate 310 and the mounting plate 320, preventing the ink from contaminating other components. Further, in order to clean the ink in the collecting groove 330, an ink suction pipe can be installed at the bottom of the follower plate 310, and the other end of the ink suction pipe can be connected to a corresponding liquid pump, and the ink in the collecting groove 330 is pumped away by the pump to complete the cleaning.

[0055] When the inkjet printer is in standby or after printing, external light will shine on the nozzle 900, causing the ink to solidify and block the outlet, thus affecting the life of the nozzle 900. Therefore, it is necessary to isolate the light from the nozzle 900 to keep its outlet in a moist state when in standby or after printing.

[0056] An end of the outer peripheral circle of the mounting plate 320 of the present application, in a direction away from the follower plate 310, is provided with a sealing ring 600.

[0057] When standby or printing is required, only the first linear drive module 100 and the second linear drive module 200 need to cooperate to make the follower plate 310 on the mounting plate 320 cover the nozzle 900, so as to isolate the light from the nozzle 900, so that the outlet of the nozzle 900 will not solidify, and the blockage of the outlet of the nozzle 900 is prevented.

[0058] A detachable member 500 is provided on the follower 300, the ink removing member 400 is detachably connected to the follower 300 through the detachable member 500, the detachable member 500 includes a base 510, an installation groove 520 is formed at an end of the base 510, an installation seat 530 is detachably arranged in the installation groove 520, and the ink removing member 400 is fixedly arranged on the installation seat 530.

[0059] Refer to Figure 3 、 Figure 4 and Figure 7 As shown, the ink removing member 400 may be worn after long-term use. Therefore, it is necessary to replace the ink removing member 400. For the convenience of replacement, the ink removing member 400 is connected to the follower plate 310 through the detachable member 500, and the detachable member 500 is located in the collecting groove 330.

[0060] Specifically, in the present embodiment, the ink removal component 400 and the mounting seat 530 are fixedly connected, the base 510 is fixedly mounted on the driven plate 310, the ink removal component 400 is fixedly mounted on the mounting seat 530, the mounting seat 530 is inserted into the mounting groove 520 to complete the installation, and the mounting seat 530 is locked by the easy-to-disassemble structure 540. When the easy-to-disassemble structure 540 is unlocked, the mounting seat 530 can be pulled out of the mounting groove 520, and the disassembly is completed quickly, so that the replacement can be completed by only replacing the new ink removal component 400 and inserting it into the mounting groove 520.

[0061] The easy-to-disassemble part 500 includes an easy-to-disassemble structure 540, and the mounting seat 530 can be detachably installed in the mounting groove 520 through the easy-to-disassemble structure 540; the easy-to-disassemble structure 540 includes a card slot 541 opened on the inner wall of the mounting groove 520, and the easy-to-disassemble structure 540 also includes a deformable member 542 arranged on the side wall of the mounting seat 530, and the deformable member 542 is partially connected to the mounting seat 530, and a card block 543 adapted to the card slot 541 is arranged on the side wall of the deformable member 542 away from the mounting seat 530, and an unlocking part 544 is arranged at the end of the deformable member 542 away from the connection with the mounting seat 530.

[0062] Continue reading Figure 7 As shown, in this embodiment, the deformable member 542 and the mounting seat 530 are integrally formed, and the deformable member 542 can be bent toward or away from the side wall of the mounting seat 530 when subjected to force.

[0063] In order to enable the mounting seat 530 to be quickly plugged in and out of the mounting slot 520, during the process of inserting the mounting seat 530 into the mounting slot 520, the deformable member 542 is deformed to a certain extent due to the obstruction of the inner wall of the mounting slot 520. As the mounting seat 530 continues to be inserted into the mounting slot 520, the clamping block 543 will be inserted into the clamping slot 541, thereby locking the mounting seat 530.

[0064] When it is necessary to pull out the mounting seat 530 from the mounting slot 520, it is only necessary to manually press the unlocking portion 544 to move it toward the side wall of the mounting seat 530. The deformable member 542 is deformed to make the block 543 disengage from the slot 541, thereby unlocking the mounting seat 530. After unlocking, it is only necessary to pull out the mounting seat 530 from the mounting slot 520.

[0065] The included angle between the ink removal member 400 and the vertical plane is α, which satisfies: 15°≤α≤30°.

[0066] See also Figure 8As shown, when wiping, the ink removal member 400 needs to be closely attached to the outlet position of the nozzle 900. If the ink removal member 400 is vertically arranged, its end is not easily deformed and not easily closely attached to the position of the nozzle 900. In order to clean and wipe the outlet of the nozzle 900 thoroughly, the ink removal member 400 needs to have a certain inclination angle. Therefore, when wiping is required, due to its certain angle, it is more likely to deform and contact the surface of the outlet of the nozzle 900; in this embodiment, the included angle between the ink removal member 400 and the vertical plane can be 15°, 20°, 25°, 30°, etc. In this embodiment, the included angle between the ink removal member 400 and the vertical plane includes the above angles but is not limited to them.

[0067] A positioning component 700 is arranged between the first moving member 150 and the bottom plate 110. The positioning component 700 includes a sensor 710 and a triggering member 720. Among them, the sensor 710 is fixedly installed on the bottom plate 110, and the triggering member 720 is fixedly installed on the first moving member 150.

[0068] Refer to Figure 1 、 Figure 3 and Figure 4 As shown, during the descending process of the first moving member 150, in order to prevent the first moving member 150 from descending too far and colliding with other components, it is necessary to limit the height of the first moving member 150. Specifically, when the first moving member 150 descends, it drives the triggering member 720 to descend as well. After the triggering member 720 descends a certain distance, it will be located at the position of the sensor 710, thereby triggering the sensor 710. After the sensor 710 is triggered, the first rotation driving member 140 stops working, that is, the first moving member 150 stops descending, thus realizing the positioning of the first moving member 150.

[0069] In this embodiment, the sensor 710 is a photoelectric sensor, and the triggering member 720 is a baffle.

[0070] Furthermore, different from the above, the sensor 710 is fixedly installed on the first moving member 150, and the triggering member 720 is fixedly installed on the bottom plate 110.

[0071] That is, the sensor 710 follows the first moving member 150 to descend. When the sensor 710 descends to the position of the triggering member 720 located on the bottom plate 110, the sensor 710 is triggered, and the positioning function can also be realized.
