Description

Technical Field

[0001] The invention relates to the technical field of printers, and in particular to an inkjet regulating mechanism for a printer. Background Art

[0002] An inkjet printer is a common printing device that forms images or text by ejecting ink in the form of tiny droplets onto a printing medium such as paper. In the process of inkjet printing, the relationship between the position of the inkjet component (usually the nozzle assembly) and the paper has an important impact on the print quality, especially the inkjet clarity.

[0003] At present, many inkjet printers mainly use the method of adjusting the distance between the inkjet element and the paper up and down to adjust the inkjet clarity. The principle is that by changing the vertical distance between the inkjet element and the paper surface, the accuracy of the ink droplets sprayed onto the paper and the penetration and diffusion of the ink on the paper can be adjusted. When the inkjet element is closer to the paper, the ink droplet spraying point is relatively more accurate, and the ink diffusion range on the paper is smaller, which can present clearer lines and more delicate image details; when the distance is appropriately increased, it may be suitable for some paper types with different requirements for ink penetration or special printing effects. But in general, a reasonable vertical distance setting is one of the key factors to ensure inkjet clarity.

[0004] In actual printing operations, paper may deviate during the paper feeding process. This problem can be caused by many factors, such as wear of mechanical parts of the paper feeding mechanism, poor flatness of the paper itself, dust or debris in the paper feeding channel interfering with the normal feeding of the paper, etc. When the paper deviates, printing quality problems such as partial loss, blurring, and ghosting of images or text may occur.

[0016] The working principle and beneficial effects of the present invention are: In the present invention, the mounting frame is slidably arranged on the frame in the horizontal direction. The mounting frame can be slidably connected to the frame through a guide rail slider structure. The inkjet component is slidably arranged on the mounting frame in the vertical direction. When it is detected that the paper has been correctly placed and is ready to receive the printed content, the printer control system starts the printing program. During the printing process, if it is found that the paper is offset in the horizontal direction, the mounting frame is manually driven to slide in the horizontal direction on the frame, so that the inkjet component can always be located in a horizontal position directly above the paper, ensuring that the ink droplets ejected by the inkjet component can accurately fall on the predetermined position of the paper, avoiding the problem of missing or blurring the printed content caused by the horizontal offset of the paper. According to the type of printing paper (such as ordinary printing paper, photo paper, etc.) and the required printing quality requirements (such as high definition, ordinary text printing, etc.), the vertical position of the inkjet component on the mounting frame is manually adjusted. For example, when it is necessary to print a high-definition photo, the control system drives the inkjet component to slide downward along the vertical slide on the mounting frame, so that the inkjet component is close to the surface of the paper, so that the droplet droplet can be more accurate, and the ink diffusion range on the paper is smaller, thereby presenting clearer image details. When printing ordinary text, the inkjet part may slide upward appropriately according to the default settings or the specific needs of the user to adapt to the requirements of different papers for ink penetration. The design that the mounting frame can be slidably set on the frame in the horizontal direction, and the inkjet part can be slidably set on the mounting frame in the vertical direction, so that the inkjet part can be accurately located at the appropriate position directly above the paper for inkjet regardless of the horizontal deviation of the paper or for different paper types and printing quality requirements. This can effectively avoid problems such as inaccurate ink droplet landing points and uneven ink diffusion caused by paper deviation or improper distance between the inkjet part and the paper, thereby significantly improving the clarity, integrity and accuracy of printed images and texts, and presenting a higher quality printing effect. Since the adjustment mechanism can effectively ensure the correct positional relationship between the inkjet part and the paper, a relatively stable and reliable printing effect can be obtained every time printing. Users no longer need to worry about problems such as printing failure and poor quality caused by paper deviation or improper adjustment of the inkjet part, thereby enhancing users' trust and recognition of printer products.

DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, they can also be understood as further technical solutions without creative work. In some figures, components with the same structure or function are only schematically illustrated, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0021] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Reference Figure 1 to Figure 13 , which is the first embodiment of the present invention, proposes a printer inkjet adjustment mechanism, including: a frame 1; a mounting frame 2, which is slidably arranged on the frame 1 along the horizontal direction; an inkjet component 3, which is slidably arranged on the mounting frame 2 along the vertical direction. After the mounting frame 2 slides, it is used to drive the inkjet component 3 to be located directly above the paper.

[0024] In this embodiment, the mounting frame 2 is slidably arranged on the frame 1 in the horizontal direction. The mounting frame 2 can be slidably connected to the frame 1 through a guide rail slider structure. The inkjet component 3 is slidably arranged on the mounting frame 2 in the vertical direction. When it is detected that the paper has been correctly placed and is ready to receive the printed content, the printer control system starts the printing program. During the printing process, if it is found that the paper is offset in the horizontal direction, the mounting frame 2 is manually driven to slide in the horizontal direction on the frame 1, so that the inkjet component 3 can always be located in a horizontal position directly above the paper, ensuring that the ink droplets ejected by the inkjet component 3 can accurately fall on the predetermined position of the paper, avoiding problems such as missing or blurred printed content caused by horizontal offset of the paper. According to the type of printing paper (such as ordinary printing paper, photo paper, etc.) and the required printing quality requirements (such as high definition, ordinary text printing, etc.), the vertical position of the inkjet component 3 on the mounting frame 2 is also manually adjusted. For example, when it is necessary to print a high-definition photo, the control system will drive the inkjet element 3 to slide downward along the vertical slide on the mounting frame 2, so that the inkjet element 3 is close to the surface of the paper, so that the ink droplet droplet can be sprayed more accurately, and the ink can be spread on the paper in a smaller range, thereby presenting clearer image details. When printing ordinary text, the inkjet element 3 may slide upward appropriately according to the default setting or the user's specific needs to adapt to the requirements of different papers for ink penetration. The design that the mounting frame 2 can be slidably arranged on the frame 1 in the horizontal direction, and the inkjet element 3 can be slidably arranged on the mounting frame 2 in the vertical direction, so that the inkjet element 3 can be accurately located at the appropriate position directly above the paper for inkjet regardless of the horizontal deviation of the paper or for different paper types and printing quality requirements. In this way, problems such as inaccurate ink droplet droplet droplet droplet and uneven ink diffusion caused by paper deviation or improper distance between the inkjet element 3 and the paper can be effectively avoided, thereby significantly improving the clarity, integrity and accuracy of the printed image and text, and presenting a higher quality printing effect. Since the adjustment mechanism can effectively ensure the correct positional relationship between the inkjet element 3 and the paper, a relatively stable and reliable printing effect can be obtained each time printing. Users no longer need to worry about problems such as printing failure and poor quality caused by paper deviation or improper adjustment of the inkjet element 3, thereby enhancing users' trust and recognition of the printer product.

[0025] Furthermore, it also includes: two fixing blocks 4, which are arranged on the frame 1, and the two fixing blocks 4 form a sliding space 41, and the mounting frame 2 is slidably arranged in the sliding space 41; there are a plurality of first studs 5, which are respectively arranged on the two fixing blocks 4 corresponding to the threads, and after the first studs 5 are rotated, they are used to adjust the size of the sliding space 41.

[0026] In this embodiment, two fixing blocks 4 are prepared, and they are installed at the pre-prepared installation positions on the frame 1 according to the design requirements, so that the two fixing blocks 4 form a sliding space 41. The mounting frame 2 is taken, and the mounting frame 2 can not only slide in the sliding space 41, but also carry the inkjet component 3. A plurality of first studs 5 are prepared, and threaded holes matching the first studs 5 are pre-processed on the fixing block 4, and the first studs 5 are screwed into the threaded holes. Each first stud 5 is threadedly connected to the fixing block 4 to achieve uniform and effective adjustment of the size of the sliding space 41, and prevent the sliding range of the mounting frame 2 from being too large, so that the mounting frame 2 slides out of the sliding space 41.

[0027] Furthermore, it also includes: two limit blocks 6, which are respectively arranged on the two fixed blocks 4, and the two limit blocks 6 are both located in the sliding space 41, and the limit blocks 6 have plug-in holes 61; there are two positioning columns 7, which are arranged at both ends of the mounting frame 2 along the sliding direction of the mounting frame 2, and the positioning columns 7 have a clamping table 71. After the mounting frame 2 slides, it is used to drive the positioning columns 7 to be inserted into the plug-in holes 61, and the clamping table 71 is clamped on the limit blocks 6.

[0028] In this embodiment, two limit blocks 6 are respectively installed on two fixed blocks 4, and they are both located in the sliding space 41. During installation, the limit block 6 can be firmly fixed to the specified position of the fixed block 4 by using suitable screws or other fastening methods. A plug-in hole 61 is processed on each limit block 6. The size and shape of the plug-in hole 61 need to be designed according to the positioning column 7 to be inserted later. It is necessary to ensure that the positioning column 7 can be smoothly inserted therein. At the same time, the inner wall of the plug-in hole 61 needs to be smooth to reduce friction during the insertion process. Each positioning column 7 is processed with a clamping table 71, which can contact the limit block 6 and prevent the positioning column 7 from completely passing through the plug-in hole 61. For example, the clamping table 71 can be designed as a ring-shaped protrusion 111 structure, and its outer diameter is slightly larger than the diameter of the plug-in hole 61 on the limit block 6. When the positioning column 7 is inserted into the plug-in hole 61, the clamping table 71 is just clamped on the limit block 6 to form a limit.

[0029] When the paper is offset in the horizontal direction, the worker will drive the mounting frame 2 to slide horizontally in the sliding space 41 according to the direction and degree of the paper offset. During the sliding process of the mounting frame 2, as the mounting frame 2 moves, the positioning column 7 in the sliding direction of the mounting frame 2 will gradually approach the corresponding plug-in hole 61 on the limit block 6. When the mounting frame 2 slides into place, the positioning column 7 will penetrate into the plug-in hole 61, and the clamping table 71 on the positioning column 7 will be firmly clamped on the limit block 6. The clamping of the positioning column 7 and the plug-in hole 61 and the abutment of the first stud 5 and the mounting frame 2 form a double limit for the mounting frame 2, ensuring the sliding range of the mounting frame 2 and completely preventing the mounting frame 2 and the inkjet component 3 from falling due to improper operation.

[0030] Furthermore, it also includes: a second stud 8, one end of which is threadedly arranged on the inkjet component 3, and the other end is rotatably arranged on the mounting frame 2. After the second stud 8 is rotated, it is used to drive the inkjet component 3 to rise and fall.

[0031] In this embodiment, one end of the second stud 8 is threadedly arranged above the inkjet component 3. When the second stud 8 is rotated, the inkjet component 3 can be effectively driven to perform lifting and lowering actions. A suitable rotating mounting structure is arranged on the upper end surface of the mounting frame 2 for the other end of the second stud 8. For example, a mounting seat with a bearing can be installed on the mounting frame 2, and the other end of the second stud 8 is inserted into the bearing, so that the second stud 8 can be stably rotated on the mounting frame 2 without axial displacement, thereby ensuring the normal performance of its rotation function, so as to drive the inkjet component 3 to accurately lift and lower in the vertical direction through rotation. The thread has a self-locking effect, so the lifting and lowering of the inkjet component 3 is designed as a structure in which the stud is threadedly arranged on the inkjet component 3, and the height of the mounting frame 2 remains unchanged. When the second stud 8 rotates, the distance between the mounting frame 2 and the inkjet component 3 becomes larger or smaller, thereby realizing the rise and fall of the inkjet component 3. After the second stud 8 stops rotating, the height of the inkjet component 3 is fixed and will not be accidentally lifted or lowered.

[0032] Furthermore, it also includes: One end of the limiting column 9 is threadedly arranged on the inkjet component 3, and the other end abuts against the mounting frame 2. After the limiting column 9 abuts against the mounting frame 2, it is used to prevent the inkjet component 3 from falling.

[0033] In this embodiment, in order to prevent the inkjet component 3 from falling excessively, the other end of the limiting column 9 is placed in a state of abutting the mounting frame 2. The specific operation can be achieved by adjusting the threaded depth of the limiting column 9 on the inkjet component 3 so that the other end of the limiting column 9 just lightly abuts the specified position of the mounting frame 2. This position is usually the lowest position that the inkjet component 3 may fall to, and can effectively prevent the inkjet component 3 from falling further when necessary. Through the design that one end of the limiting column 9 is threadedly set on the inkjet component 3 and the other end abuts the mounting frame 2, when adjusting the vertical position of the inkjet component 3, the inkjet component 3 can be effectively prevented from falling excessively, thereby controlling the distance between the inkjet component 3 and the paper. The droplet injection point is made more accurate, and the diffusion range of the ink on the paper is smaller, avoiding the problems of uneven ink diffusion, blurred images or text caused by the inkjet component 3 being too close to the paper, significantly improving the clarity, integrity and accuracy of the printed images and texts, and presenting a higher quality printing effect.

[0034] The operation of the entire inkjet adjustment mechanism remains simple, which improves the convenience and satisfaction of users in using the printer.

[0035] Furthermore, the inkjet component 3 includes: a mounting shell 31, which is slidably arranged on the mounting frame 2 along the vertical direction, and the second stud 8 and the limiting column 9 are both threadedly arranged on the mounting shell 31; a bottom plate 32, which is swingably arranged on the mounting shell 31; and a plurality of inkjet units 33, which are arranged at intervals on the bottom plate 32. After the bottom plate 32 swings, the inkjet units 33 are driven to be arranged parallel to the paper.

[0036] In this embodiment, the mounting shell 31 is slidably mounted on the mounting frame 2 in the vertical direction, and the bottom plate 32 can swing at a certain angle relative to the mounting shell 31. The bottom plate 32 swings flexibly without any jamming, and can adjust the angle within a certain range. The inkjet unit 33 is usually the core component of the printer's inkjet function. These inkjet units 33 are evenly arranged on the bottom plate 32 at certain intervals. When the paper is deflected, the worker can rotate the bottom plate 32 to drive the inkjet unit 33 to rotate, so that the inkjet unit 33 remains parallel to the paper. Furthermore, one end of the bottom plate 32 has a fixing hole 321, and also includes: a fixing shaft 10, which is arranged on the mounting shell 31, and the other end of the bottom plate 32 is swingably arranged on the fixing shaft 10; a turntable 11, which is rotatably arranged on the mounting shell 31, and the turntable 11 has an eccentrically arranged protrusion 111, and the protrusion 111 is clamped in the fixing hole 321. After the turntable 11 rotates, it drives the bottom plate 32 to swing, and the bottom plate 32 swings along the fixing shaft 10 through the opening groove.

[0037] In this embodiment, a fixed shaft 10 is installed on the mounting shell 31 at a position corresponding to the other end of the bottom plate 32. The turntable 11 is rotatably set on the mounting shell 31, and the turntable 11 can rotate on the mounting shell 31. The other end of the bottom plate 32 is swingably set on the fixed shaft 10, so that the bottom plate 32 can rotate around the fixed shaft 10. Then, the protrusion 111 on the turntable 11 is snap-fitted into the fixed hole 321 at one end of the bottom plate 32, and the turntable 11 can drive the bottom plate 32 to rotate along the fixed shaft 10 when it rotates. By reasonably adjusting the rotation angle of the turntable 11, the inkjet unit 33 on the bottom plate 32 can be restored to a parallel setting with the paper, ensuring that the distance between each inkjet unit 33 and the paper is relatively uniform, thereby ensuring that the ink droplets can be accurately sprayed onto the paper and improving the printing quality. Since the relative position of the inkjet component 3 and the paper can be finely adjusted in multiple dimensions, the inkjet adjustment mechanism can adapt well to papers in various states. Even if the paper has these common undesirable conditions, by timely adjusting the position and angle of the inkjet component 3, it is still possible to ensure that clear and complete images and texts are printed on the paper, further improving the stability of the printing quality.

[0038] Furthermore, the turntable 11 has a first through hole 112, and the mounting shell 31 has a second through hole 311. The first through hole 112 is connected to the second through hole 311, and also includes: a connecting rod 12, which is lifted and lowered in the first through hole 112; a third screw rod 13, one end of which is clamped in the second through hole 311, and the other end is threaded in the connecting rod 12; a cam 14, which is rotatably set on the connecting rod 12, and the turntable 11 is located between the cam 14 and the mounting shell 31, and the cam 14 is in contact with the turntable 11. After the cam 14 rotates, it squeezes the turntable 11 with the mounting shell 31.

[0039] In this embodiment, the rotating disk 11 is located between the cam 14 and the mounting shell 31 , and the cam 14 and the rotating disk 11 can be closely abutted, so that when the cam 14 rotates, the rotating disk 11 can be squeezed by the cooperation with the mounting shell 31 .

[0040] When the paper changes in any position, angle, etc., the worker can drive the corresponding adjustment mechanism to make adjustments. This includes not only the sliding of the mounting frame 2, the vertical adjustment of the inkjet component 3, the swing adjustment of the bottom plate 32, etc., but also the swing of the bottom plate 32 is first unlocked, and the cam 14 rotates to drive the connecting rod 12 down, and the connecting rod 12 drives the third screw 13 down after it is lowered, and the distance between the contact surface of the cam 14 and the turntable 11 and the mounting shell 31 increases, and the friction force on the turntable 11 is reduced, so that the bottom plate 32 can swing. Otherwise, the bottom plate 32 cannot swing.

[0041] Furthermore, it also includes: a plurality of rollers 15, the rollers 15 are used to transport paper, and the paper is located between the rollers 15 and the inkjet unit 33; a mounting plate 16, which is arranged on the frame 1 and is located below the rollers 15; a first sliding member 17, which has two, is synchronously slidably arranged on the mounting plate 16, and is located on one side of the paper; a second sliding member 18, which has two, is synchronously slidably arranged on the mounting plate 16, and is located on the other side of the paper; a first connecting rod 19, which connects the two first sliding members 17, and the two first sliding members 17 slide synchronously through the first connecting rod 19; a second connecting rod 20, which connects the two second sliding members 18, and the two second sliding members 18 slide synchronously through the second connecting rod 20. It also includes: a third connecting rod 21, which has two parts, one end of which is arranged on a first sliding member 17, and the other end is arranged on a second sliding member 18, and the third connecting rod 21 drives the first sliding member 17 and the second sliding member 18 to slide synchronously; a fourth connecting rod 22, one end of which is arranged on the first connecting rod 19, and the other end is arranged on the mounting frame 2. After the first connecting rod 19 slides, the mounting frame 2 is driven to slide through the fourth connecting rod 22. The first sliding member 17 and the second sliding member 18 both include: a sliding rod 171, which is slidably arranged on the mounting plate 16, and the sliding rod 171 slides close to or away from the paper; an abutment block 172, one end of which is slidably arranged in the sliding rod 171, and the other end abuts the paper, and is used to drive the abutment block 172 to slide after the paper is offset; an elastic member 173, one end of which is arranged on the sliding rod 171, and the other end is arranged on the abutment block 172, and the elastic member 173 is used to provide a force for the abutment block 172 to abut the paper.

[0042] In this embodiment, a plurality of rollers 15 are prepared to transport paper. These rollers 15 are installed at appropriate positions in the printer according to the design requirements so that they can work together to provide stable power for paper transportation. The mounting plate 16 is located below the rollers 15 to avoid the paper. Suitable sliding tracks are prepared on the mounting plate 16 for the first sliding member 17 and the second sliding member 18. Each of the first sliding member 17 and the second sliding member 18 includes a sliding rod 171, an abutment block 172 and an elastic member 173. A structure (such as a slider) that is compatible with the sliding track on the mounting plate 16 is processed at one end of the sliding rod 171, so that the sliding rod 171 is slidably set on the mounting plate 16. One end of the abutment block 172 is slidably set in the sliding rod 171, and the other end can abut the paper. At this time, the paper does not generate pressure on the abutment block 172. One end of the elastic member 173 is fixed at a corresponding position inside the sliding rod 171, and the other end is connected to the abutment block 172. When the paper is offset, the two abutment blocks 172 of the first sliding member 17 or the two abutment blocks 172 of the first sliding member 17 are squeezed at the same time, and the abutment block 172 squeezes the elastic member 173. Since the elastic member 173 in this embodiment is extremely sensitive, the paper will not be damaged. A detection member is designed on the sliding rod 171. When the elastic member 173 contracts, the detection member can monitor the state of the elastic member 173 in real time and send a signal to the driving member. The driving member drives the first sliding member 17 and the second sliding member 18 to deviate at the same time. The reason why the first sliding member 17 and the second sliding member 18 slide synchronously through the connection of the third connecting member is to ensure that the paper is always located between the first sliding member 17 and the second sliding member 18, and always keep in contact with the abutment block 172 of the first sliding member 17 and the second sliding member 18, to prevent the paper from being unable to abut and squeeze the abutment block 172 after secondary deflection, and then the detection member cannot detect. When the paper only squeezes one of the abutment blocks 172, it means that the paper is not simply deflected, and the detection member will send a signal to the alarm, and the alarm will sound an alarm to remind the worker that the paper is abnormal. In order to ensure that the inkjet component 3 can follow the deviation in real time after the paper is deviated, the fourth connecting member is designed in this embodiment to connect the first sliding member 17 and the second sliding member 18 with the inkjet component 3. Through the driving of the driving member, the first sliding member 17 and the second sliding member 18 and the inkjet component 3 are driven to move at the same time, so that the state of the paper can be detected in real time and the paper can be followed in real time. The sliding rod 171 includes a square structure that slides horizontally along the mounting plate 16, a cylindrical structure that provides a sliding position for the abutment block 172, and a connecting rod 12 that connects the square structure and the cylindrical structure. In this embodiment, this structural design not only reduces the cost of raw materials, but also realizes the function of sliding the sliding rod 171 and providing a sliding position for the abutment block 172.In this embodiment, in order to ensure the stability of the structure, there are two mounting racks 2, and the two mounting racks 2 are arranged at intervals. There can be two fourth connecting members, one end of a fourth connecting member is arranged on the first connecting member, and the other end is connected to a first card block, the first card block can slide in the horizontal direction and is located between the two mounting racks 2, and one end of another fourth connecting member is arranged on the second connecting member, and the other end is connected to a second card block, the second card block can slide in the horizontal direction and is located between the two mounting racks 2. When the paper is deflected in any direction, the fourth connecting member can drive the inkjet member 3 to deflect. Figure 5 It can be seen that the sliding range of the inkjet component 3 is relatively large. In order to achieve sliding of only the inkjet component 3, the first clamping block and the second clamping block can be separated from the fourth connecting member in this embodiment, and only the inkjet component 3 and the mounting frame 2 can be moved.

[0043] Real-time deviation correction enables the inkjet unit 33 to maintain the correct relative position with the paper. This effectively avoids problems such as inaccurate ink droplet landing points, blurred or missing printed content, etc. caused by paper deviation. Reduce the number of shutdowns caused by paper deviation. When the paper is deviated, traditional printers may need to stop and adjust manually, which will seriously affect the printing efficiency. The adjustment mechanism can automatically detect and correct paper deviation during paper transportation without stopping, which greatly reduces the number of printing interruptions caused by paper problems and ensures the continuity of printing. Especially for a large number of printing tasks, it can significantly shorten the printing time. When the paper is deviated, the abutment block 172 can quickly transmit the change of paper position to the inkjet component 3, so that the inkjet component 3 can quickly adjust its position. This rapid response capability makes the printing process smoother, reduces the time wasted due to adjustment, and improves the printing efficiency per unit time.
