Description

Technical Field

[0001] This utility model relates to a printhead wiping assembly, and more particularly to a printhead wiping assembly used in inkjet printing. Background Technology

[0002] In the field of inkjet printing technology, the printhead is a core component, and the cleanliness of its nozzles directly determines the quality of the print output and the operational stability of the equipment. During the printing process, the printhead is inevitably exposed to dry air and comes into contact with inks of different properties, causing residual ink, dust, and other contaminants to easily accumulate on the nozzle surface and surrounding areas. If these contaminants are not removed in a timely and effective manner, they can easily cause nozzle clogging, deviation of ink droplet ejection paths, or even permanent damage, leading to a series of quality problems such as missing lines, streaks, and blurring, seriously affecting the reliability and lifespan of the printing equipment.

[0003] To maintain printhead performance, regular or on-demand cleaning and wiping are essential. Currently, common printhead wiping solutions in the industry mainly rely on a single wiping method: either wet wiping or dry wiping.

[0004] Wet wiping typically involves cleaning the printhead surface with a non-woven fabric or wiper soaked in a solvent (such as a cleaning solution or moisturizing solution). Its advantage lies in its ability to effectively dissolve and soften dried ink stains and stubborn dirt. However, simple wet wiping leaves excess liquid residue on the printhead surface. If this residue is not removed, it may unpredictably mix with the ink in subsequent printing, diluting the ink concentration, or interfere with the normal formation and ejection of ink droplets due to surface tension, thus introducing new printing defects.

[0005] Dry wiping primarily involves using a dry, clean non-woven cloth to physically scrape the printhead, aiming to absorb moisture and remove dust. However, dry wiping has limited cleaning ability for dried and solidified dirt, and forceful wiping may even scratch the surface of the precision printhead.

[0006] Many existing wiping components can only perform one function at a time and cannot automatically switch between or combine two wiping modes in a single cleaning action. Operators often need to make multiple, tedious manual interventions or change equipment configurations, resulting in inefficient cleaning processes and low levels of automation.

[0007] Therefore, it is necessary to improve a printhead wiping assembly used in inkjet printing in the prior art to solve the above problems. Summary of the Invention

[0008] This invention overcomes the shortcomings of the prior art and provides a printhead wiping assembly for inkjet printing, aiming to solve the problems in the prior art.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a printhead wiping assembly for inkjet printing, comprising: a transmission mechanism, and a wiping mechanism disposed in the middle of the transmission mechanism.

[0010] The transmission mechanism includes: symmetrically arranged vertical plates, dual drive motors mounted on the vertical plates, and a synchronous belt assembly connected to and driven by the dual drive motors; the wiping mechanism is located in the middle of the symmetrically arranged vertical plates, and a wetting groove is also provided at the bottom of the wiping mechanism;

[0011] The wiping mechanism includes: a wiping roller, a non-woven fabric disposed on the wiping roller, and a disassembly assembly connected to both ends of the wiping roller; the wiping roller is rotatably connected to the vertical plate through the disassembly assembly, and the wiping roller is fixedly connected to the synchronous belt assembly.

[0012] In a preferred embodiment of this utility model, the dual drive motor includes two servo motors arranged side by side, and two synchronous belt components are also provided, which are connected to and driven by different servo motors respectively.

[0013] In a preferred embodiment of the present invention, the synchronous belt assembly includes: a synchronous belt and a synchronous pulley meshing with the synchronous belt; the synchronous pulley is fixedly connected to a servo motor.

[0014] In a preferred embodiment of the present invention, the wetting tank is a square tank with an open top, and the two sides of the wetting tank are fixedly connected to symmetrically arranged vertical plates, and the wetting tank is filled with cleaning liquid.

[0015] In a preferred embodiment of this utility model, a plurality of foaming rollers are provided, and the wiping roller includes a foaming roller, a roll disposed on the inner side of the circumference of the foaming roller, and a guide rod disposed on the inner side of the roll. The non-woven fabric is provided with slots on both ends of the foaming roller and the roll.

[0016] In a preferred embodiment of this utility model, a spring is sleeved on one end of the guide rod, and the two ends of the spring are in contact with the guide rod and the drum, respectively. A guide hole is provided at one end of the guide rod, and the guide hole is elliptical in shape.

[0017] In a preferred embodiment of the present invention, the disassembly assembly includes a rotating block and a handle; two rotating blocks are respectively rotatably connected to the upright plate, a card plate is fixedly connected to one side of the rotating block, and a fixing groove is provided on one of the rotating blocks.

[0018] In a preferred embodiment of this utility model, the handle is T-shaped and has a sliding hole. A retaining shaft is provided in the sliding hole and is slidably connected in the guide hole. The retaining shaft can engage with the fixing groove.

[0019] In a preferred embodiment of this utility model, the wiping roller is concave, and the wiping roller located at the bottom center is disposed in the wetting tank.

[0020] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0021] (1) This utility model provides a printhead wiping assembly for inkjet printing. Through the dual drive motors and synchronous belt assemblies on the symmetrically arranged vertical plate, the dual drive motors control the two sets of synchronous belt assemblies to rotate synchronously, which in turn drive the wiping rollers to rotate. This allows the non-woven fabric to be wetted in the wetting tank for wet wiping, and then dry and clean non-woven fabric for dry wiping. This achieves a dual wiping process of first wet and then dry wiping of the printhead, effectively dissolving dirt and absorbing moisture. Compared with the common single wiping methods in the prior art, such as only wet wiping or only dry wiping, which cannot be automatically switched, this design avoids printing quality problems caused by residual liquid, improves cleaning efficiency and printhead reliability, reduces printhead clogging and failure, and thus improves the overall stability and output quality of the printing equipment.

[0022] (2) This utility model provides a printhead wiping assembly for inkjet printing. The wiping roller can be easily disassembled and installed by operating the handle and the retaining shaft. The spring and guide hole design allows users to quickly release the fixation and remove the wiping roller, enabling rapid replacement when the non-woven fabric is dirty, reducing maintenance time and operational complexity. In contrast, the wiping assembly in the prior art often requires special tools or complicated disassembly steps, resulting in long downtime and high maintenance costs. This design simplifies the replacement process, further improves the availability and maintenance efficiency of the equipment, reduces operating costs, and ensures that the wiping assembly can work continuously and efficiently, extending the service life of the equipment.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0030] As shown in the figure, a printhead wiping assembly for inkjet printing includes: a transmission mechanism 1, and a wiping mechanism 2 disposed in the middle of the transmission mechanism 1.

[0031] The transmission mechanism 1 includes: symmetrically arranged vertical plates 3, dual drive motors 4 arranged on the vertical plates 3, and synchronous belt assembly 5 connected to and driven by the dual drive motors 4; the wiping mechanism 2 is located in the middle of the symmetrically arranged vertical plates 3, and a wetting groove 6 is also provided at the bottom of the wiping mechanism 2.

[0032] The wiping mechanism 2 includes: a wiping roller 7, a non-woven fabric 8 disposed on the wiping roller 7, and a disassembly assembly 9 connected to both ends of the wiping roller 7; the wiping roller 7 is rotatably connected to the vertical plate 3 through the disassembly assembly 9, and the wiping roller 7 is fixedly connected to the synchronous belt assembly 5.

[0033] It should be noted that the wiping component of this application is assembled and installed on the inkjet printing equipment, and the inkjet printing nozzle is cleaned by controlling the reciprocating movement of the wiping component at the inkjet printing nozzle. In this wiping component, dual drive motors 4 and two sets of synchronous belt assemblies 5 are set on two symmetrically arranged vertical plates 3. The dual drive motors 4 drive the two sets of synchronous belt assemblies 5 to rotate synchronously, thereby driving the synchronous belt assemblies 5 to wipe the inkjet printing nozzle.

[0034] Furthermore, a wetting tank 6 is provided at the bottom of the synchronous belt assembly 5, and a cleaning solution is provided in the wetting tank 6. During the wiping process, the dual drive motor 4 rotates in the forward direction, driving a portion of the non-woven fabric 8 through the cleaning solution in the wetting tank 6, so that the non-woven fabric 8 is wetted by the cleaning solution in the wetting tank 6, and then passes through the inkjet printing nozzle, wiping the nozzle with a wet cloth. Then the wet non-woven fabric that has become dirty after wiping is replaced with a dry non-woven fabric. After that, the dual drive motor 4 rotates synchronously again, so that the portion of the non-woven fabric 8 that has not passed through the wetting tank 6 wipes the nozzle again with a dry cloth. In this way, the wiping is performed twice, once with a wet cloth and once with a dry cloth.

[0035] The wiping roller 7 is rotatably connected between two symmetrically arranged vertical plates 3 via the disassembly assembly 9 and is connected to two synchronous belt assemblies 5. This allows the dual drive motor 4 to drive the wiping roller 7 to rotate and wipe the nozzle via the synchronous belt assembly 5. After wiping, the non-woven fabric 8 becomes dirty. The wiping roller 7 can be disassembled via the disassembly assembly 9 to remove the dirty non-woven fabric 8 and replace it with a clean one.

[0036] The transmission mechanism 1 includes: symmetrically arranged vertical plates 3, dual drive motors 4 arranged on the vertical plates 3, and synchronous belt assembly 5 connected to and driven by the dual drive motors 4; the wiping mechanism 2 is located in the middle of the symmetrically arranged vertical plates 3, and a wetting groove 6 is also provided at the bottom of the wiping mechanism 2.

[0037] In this utility model, the dual drive motor 4 includes two servo motors arranged side by side, and the synchronous belt assembly 5 also includes two servo motors, which are connected to and driven by different servo motors respectively; the synchronous belt assembly 5 includes: a synchronous belt 10, and a synchronous pulley 11 that meshes with the synchronous belt 10; the synchronous pulley 11 is fixedly connected to the servo motor; the wetting tank 6 is a square tank with an open top, and the two sides of the wetting tank 6 are fixedly connected to the symmetrically arranged vertical plates 3 respectively, and the wetting tank 6 is filled with cleaning liquid.

[0038] It should be noted that there are two upright plates 3, arranged symmetrically. This determines the orientation of the equipment in this application. The term "inner side" in the following description refers to the position between the two upright plates 3, while the outer side refers to the position relative to the upright plates 3. The dual drive motor 4 specifically consists of two servo motors, arranged vertically side-by-side and fixedly connected to the same upright plate 3. The servo motors are located on the inner side of the upright plate 3. Two sets of synchronous belt assemblies 5 are provided, each fixedly connected to the output shaft of one of the two servo motors. Each synchronous belt assembly 5 consists of a synchronous pulley 11 and a synchronous belt 10. One of the synchronous pulleys 11 in each set is fixedly connected to a different servo motor. This is achieved by simultaneously controlling different servo motors to rotate synchronously, driving the synchronous belt assembly 5 to rotate synchronously. Wetting grooves 6 are provided on the inner sides of the two upright plates 3, and the upright plates 3 are connected and fixed through the wetting grooves 6. The wetting grooves 6 are designed as grooves, and the two sides of the wetting grooves 6 are fixedly connected to the two upright plates 3 respectively, thereby connecting and fixing the two upright plates 3. The wiping assembly of this application connects the bottom of the wetting grooves 6 to the reciprocating mobile device. By controlling the reciprocating movement of the reciprocating mobile device, the wetting grooves 6 are controlled to move back and forth, thereby driving the upright plates 3 to move back and forth. Thus, the transmission mechanism 1 and the wiping mechanism 2 of this application wipe the nozzle on the reciprocating mobile device.

[0039] The wiping mechanism 2 includes: a wiping roller 7, a non-woven fabric 8 disposed on the wiping roller 7, and a disassembly assembly 9 connected to both ends of the wiping roller 7; the wiping roller 7 is rotatably connected to the vertical plate 3 through the disassembly assembly 9, and the wiping roller 7 is fixedly connected to the synchronous belt assembly 5.

[0040] In this utility model, a plurality of wiping rollers 7 are provided. The wiping rollers 7 include foaming rollers 12, a roll 13 disposed on the inner side of the circumference of the foaming rollers 12, and a guide rod 14 disposed on the inner side of the roll 13. Non-woven fabric 8 is disposed on the foaming rollers 12. The foaming rollers 12 and the roll 13 are respectively provided with slots at both ends.

[0041] In this utility model, a spring 15 is sleeved on one end of the guide rod 14, and the two ends of the spring 15 are in contact with the guide rod 14 and the drum 13 respectively. A guide hole is opened on one end of the guide rod 14, and the guide hole is elliptical.

[0042] In this utility model, the disassembly assembly 9 includes a rotating block 16 and a handle 20; the rotating block 16 is rotatably connected to the upright plate 3, and a clamping plate 17 is fixedly connected to one side of the rotating block 16, and a fixing groove 18 is provided on one of the rotating blocks 16.

[0043] In this utility model, the handle 20 is T-shaped and has a sliding hole. A retaining shaft 19 is provided in the sliding hole and is slidably connected in the guide hole. The retaining shaft 19 can engage with the fixing groove 18.

[0044] In a preferred embodiment of the present invention, the wiping roller 7 is concave and is located in the wetting tank 6 at the bottom center.

[0045] It should be noted that there are five wiping rollers 7 arranged in a U-shape, with the two vertical sides of the U-shape symmetrically inclined. The top of the inclined surface is used to wipe the nozzle. The non-woven fabric 8 is wound around the circumference of the wiping roller 7. As the wiping roller 7 rotates, the non-woven fabric 8 wound on it rotates synchronously. The two ends of the wiping roller 7 are rotatably connected to two vertical plates 3 through the disassembly assembly 9. The disassembly assembly 9 is divided into a connecting end and a rotating end. The disassembly assembly 9 at the connecting end is set on the same vertical plate 3 as the servo motor, while the rotating end is set on another vertical plate 3. The two ends of the wiping roller 7 are fixed to the connecting end and the rotating end, respectively. At the same time, the servo motor, the synchronous belt assembly 5 and the connecting end of the disassembly assembly 9 are all set on the same vertical plate 3.

[0046] The connecting end of the disassembly assembly 9 is provided with five rotating blocks 16, which are rotatably connected to the upright plate 3. A clamping plate 17 is fixedly connected to the inner side of the rotating block 16 on the upright plate 3. The clamping plate 17 is vertically set and rotates with the rotating block 16. The five rotating blocks 16 at the connecting end are fixedly connected to one end of the wiping roller 7 on the inner side of the upright plate 3 by clamps. The two rotating blocks 16 located on the bottom sides are fixedly connected to the synchronous pulleys 11 of the two synchronous belt assemblies 5 that are not connected to the servo motors. In this way, when the two servo motors rotate, they can drive the rotating block 16 at one of the connecting ends to rotate through the two different synchronous belt assemblies 5, thereby driving the wiping roller 7 connected to this rotating block 16 to rotate, and then driving the other wiping rollers 7 to rotate through the non-woven fabric 8, and driving the non-woven fabric 8 to rotate, thereby wiping the nozzle.

[0047] The rotating end of the disassembly assembly 9 includes rotating blocks 16 and handles 20. Five rotating blocks 16 are provided here, and they are rotatably connected to the upright plate 3. A retaining plate 17 is provided on the inner rotating plate of the upright plate 3, and the retaining plate 17 can rotate with the rotating blocks 16. The rotating blocks 16 at the rotating end have a fixing groove 18 on one end outside the upright plate 3. The fixing groove 18 is hook-shaped. Both the rotating end and the connecting end of the rotating blocks 16 are hollow. The handle 20 can be slidably connected to the rotating end. A sliding hole is provided on the handle 20, and a retaining shaft 19 is slidably connected within the sliding hole. Both ends of the retaining shaft 19 can engage with the fixing groove 18, thereby fixing the handle 20 to the rotating block 16 with the hook-shaped fixing groove 18.

[0048] The wiping roller 7 includes a guide rod 14, a roll 13 sleeved on the outer circumference of the guide rod 14, and a foaming roller 12 sleeved on the outer circumference of the roll 13. Slots are provided at both ends of the foaming roller 12 and the roll 13, which can engage with the locking plates 17 on the rotating block 16. The guide rod 14 is longer than both the roll 13 and the foaming roller 12. A spring 15 is also sleeved on the circumference of the guide rod 14. Both ends of the spring 15 contact the guide rod 14 and the roll 13 respectively, and a ring-shaped protrusion is provided at the contact position with the roll 13. The other end of the spring 15 is fixed... A ring is fixedly connected to the guide rod 14, and the ring-shaped protrusion holds the spring 15 in a fixed position. A guide hole is also provided on the guide rod 14, which is located at the ring and is elliptical in shape. The retaining shaft 19 is slidably connected in the guide hole and also slidably connected in the sliding hole of the handle 20. As the handle 20 is pressed down, it will drive the retaining shaft 19 to move, thereby compressing the spring 15. Moreover, due to the blocking effect of the drum 13 on the spring 15, after the downward pressure on the handle 20 is released, the spring 15 returns to its original deformation and pushes the handle 20 to move backward.

[0049] On the end of the guide rod 14 away from the handle 20, a slot is provided on the guide rod 14, and a retaining spring is provided on the slot. The guide rails at the connecting end and the rotating end are both provided with through holes at the center. During the installation process, the guide rails are installed by passing through the through holes, and one end of the guide rail is locked onto the rotating block 16 by the retaining spring, while the other end is fixed onto the handle 20 by passing through the sliding hole of the handle 20 by the retaining shaft 19.

[0050] In this way, during installation, the foaming roller 12 is first fitted onto the drum 13, and the slots at both ends are aligned. Then, the slots are secured onto the retaining plate 17 of the rotating block 16. Next, the guide rod 14 is passed through the through hole of the rotating block 16. At this point, the spring 15 is fitted onto the guide rod 14, and the retaining spring is used to fix the guide rod 14 to the rotating block 16 at the connecting end. Two servo motors are fixed to the vertical plate 3 and connected to two sets of synchronous belt assemblies 5 for transmission. The two synchronous belt assemblies 5 are then fixedly connected to the rotating blocks 16 at two different connecting ends. The foaming roller 12 and the drum 13 are limited by the retaining plate 17 and the guide rod 14, and are driven by the rotation of the two servo motors. During installation, the guide rod 14 passes through the rotating block 16 and the guide shaft 19 passes through the sliding hole and the guide hole respectively, thus connecting the guide rod 14 and the handle 20. Then, by pressing down the handle 20, the spring 15 is squeezed, and the retaining shaft 19 moves along the fixing groove 18 on the rotating block 16, so that the retaining shaft 19 is locked at the end of the fixing groove 18. At this time, the squeezing force on the spring 15 cannot be removed, so that the retaining shaft 19 is always locked on the rotating block 16, thus completely fixing the retaining shaft 19 on the rotating block 16. When it is necessary to clean the non-woven fabric 8, push the handle 20 to move the retaining shaft 19 out of the rotating block 16 along the fixing groove 18, so that the guide rod 14 can be removed and the foaming roller 12 and the roll 13 can be removed for replacement.

[0051] In use, the printhead wiping assembly is installed on an inkjet printing device. An external reciprocating device drives the entire assembly to move horizontally back and forth below the printhead. During operation, the two servo motors in the dual drive motor 4 control the operation of two sets of synchronous belt assemblies 5. When the printhead needs to be cleaned, the two servo motors rotate in the forward direction, driving the corresponding wiping roller 7 to rotate through the synchronous belt assembly 5 fixedly connected to them. The wiping roller 7 is located in or near the wetting tank 6. During the rotation, the non-woven fabric 8 wrapped around its surface passes through the cleaning liquid in the wetting tank 6 in sequence. After absorbing the cleaning liquid, the non-woven fabric 8 becomes wet and then performs wet wiping on the printhead surface as the assembly moves horizontally, effectively dissolving and removing ink stains and dirt attached to the printhead.

[0052] After wet wiping is completed, the soiled non-woven fabric 8 is replaced with a clean, dry non-woven fabric 8. The two servo motors are started again to rotate, driving the synchronous belt 11 and the wiping roller 7 connected to it to rotate again. The non-woven fabric 8 on the wiping roller 7 has not passed through the wetting tank 6 and remains dry. At this time, the dry non-woven fabric 8 performs a second dry wipe on the printhead that has just been wet-wiped, absorbing the residual cleaning liquid and moisture, ensuring that the printhead surface is quickly dried and clean, and avoiding liquid residue from affecting the printing quality.

[0053] After wiping, if the non-woven fabric 8 becomes soiled again and needs to be replaced, the operator can push the T-shaped handle 20 at one end of the wiping roller 7 to move the retaining shaft 19 out along the fixing groove 18 on the rotating block 16, thus releasing the fixation of the guide rod 14. The guide rod 14, along with the foaming roller 12 and the roll 13 mounted on it, can then be removed from between the vertical plates 3. The soiled non-woven fabric 8 can be removed and replaced with a new one. During reinstallation, the guide rod 14 is pushed back through the through hole of the rotating block 16, and the spring 15 is re-pressed and locked in the fixing groove 18 through the cooperation of the retaining shaft 19 and the handle 20, thus completing the assembly. The equipment can then continue to perform wiping tasks.

[0054] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
