Description

Technical Field

[0001] This utility model relates to a nozzle cleaning device for an inkjet printer, specifically a nozzle cleaning device for an inkjet printer, and belongs to the field of inkjet printer technology. Background Technology

[0002] An inkjet printer is a software-controlled device that marks products in a non-contact manner. It uses charged ink particles deflected by a high-voltage electric field to print patterns, text, and numbers on the surface of various objects. It is a high-tech product integrating electromechanical systems. During the operation of an inkjet printer, the nozzles of the ink printhead often encounter ink adhesion, which affects the ejection direction of the ink line. At this time, it is necessary to clean the nozzles of the inkjet printer.

[0003] A coding machine nozzle cleaning device disclosed in Chinese Patent Application Publication CN219856491U improves the sealing between the cleaning disc and the printhead by setting a sealing ring, preventing wastewater from flowing out during cleaning of the coding machine nozzles. A support plate and limiting frame limit and support the connecting pipe, thereby suspending the cleaning disc. Foot pads support the main body of the coding machine, reducing the direct entry of external moisture into the machine's interior. An inlet pipe allows for easy addition of cleaning fluid to the cleaning tank for cleaning the coding machine nozzles. A drain pipe facilitates the centralized discharge of wastewater generated during nozzle cleaning. An electric push rod and casters allow for easy movement of the coding machine main body when needed.

[0004] In the above patented solutions, the wastewater generated during the cleaning process flows sequentially through the cleaning tray and connecting pipe 2 until it flows into the collection tank for storage and collection. However, during the cleaning process, the cleaning fluid will carry away the oil, ink, and tiny solid particles inside and outside the nozzle. These impurities may deposit on the inner wall of the connecting pipe. After long-term use, the accumulation of impurities will cause the connecting pipe to become blocked, which will lead to poor wastewater discharge, reduced cleaning efficiency, and increased maintenance difficulty.

[0005] Therefore, a nozzle cleaning device for inkjet printers is proposed here. Utility Model Content

[0006] This invention proposes a nozzle cleaning device for inkjet printers, which can filter and clean the sewage flowing into the collection pipe, thereby improving cleaning efficiency.

[0007] This utility model is achieved through the following technical solution: a coding machine nozzle cleaning device, including a coding machine body, a cleaning component and a collection component on the coding machine body, an anti-clogging component on the collection component, an inkjet tube fixedly connected to one side of the coding machine body, and a printhead fixedly connected to the end of the inkjet tube away from the coding machine body.

[0008] The collection assembly includes a collection box fixed to the back of the inkjet printer body. A collection tube is fixedly connected to one side of the collection box. An insert tube is inserted into the end of the collection tube away from the collection box. A collection cylinder is fixedly connected to the top of the insert tube, and the collection cylinder is adapted to the printhead.

[0009] The anti-clogging component includes an installation groove formed on the outer surface of the collection pipe and a second fixing block fixed on the outer surface of the collection pipe. An arc-shaped plate is hinged to the inner wall of the installation groove, and the arc-shaped plate is sealed to the installation groove. A filter screen is fixed on one side of the arc-shaped plate inside the collection pipe, and the outer surface of the filter screen is in contact with the inner wall of the collection pipe. A first fixing block is fixed on the outer surface of the arc-shaped plate, and the first fixing block and the second fixing block are in contact.

[0010] A limiting groove is formed on the first fixing block. A sliding rod is slidably connected to the inner wall of the hole on the second fixing block. One end of the sliding rod passes through the limiting groove and penetrates the first fixing block. A limiting plate is fixed to the outer surface of the sliding rod near the limiting groove, and the limiting plate intersects with the limiting groove. A limiting block is fixed to the end of the sliding rod away from the limiting plate. A spring is sleeved on the outer surface of the sliding rod, and the spring is located between the second fixing block and the limiting block.

[0011] Furthermore, a support plate is fixed to one side of the inkjet printer body, and the inner wall of the hole on the support plate is fixed to the outer surface of the collection tube.

[0012] Furthermore, a drain pipe is fixedly connected to one side of the collection box, and a control valve is installed on the drain pipe.

[0013] Furthermore, the cleaning assembly includes a water tank and a water pump fixed on the upper surface of the inkjet printer body, with the water pump input end connected to the water tank, the water pump output end fixedly connected to a water outlet pipe, and the end of the water outlet pipe away from the water pump fixedly connected to the print head, and a liquid inlet pipe fixedly connected to one side of the water tank, with control valves provided on both the liquid inlet pipe and the water outlet pipe.

[0014] Furthermore, a mounting base is fixed to the upper surface of the inkjet printer body, and the upper surface of the mounting base is fixed to the outer surface of the water pump.

[0015] Furthermore, the bottom surface of the inkjet printer body is fixed with multiple support legs.

[0016] This utility model provides a nozzle cleaning device for inkjet printers, which has the following beneficial effects:

[0017] 1. The nozzle cleaning device for this inkjet printer involves pulling the collection cylinder upwards to connect it to the printhead during cleaning, until the collection cylinder is in tight contact with the sealing ring. Then, the water pump is activated to extract water from the water tank, which flows through the outlet pipe into the interior of the printhead and finally out of the nozzles on the printhead, cleaning the oil stains inside the nozzles. The wastewater generated during the cleaning process passes through the collection cylinder, the insertion pipe, and the collection pipe in sequence until it flows into the collection box for storage and collection.

[0018] 2. In this inkjet printer nozzle cleaning device, when wastewater generated during the cleaning of the printhead passes through the collection pipe, the filter screen can collect impurities in the wastewater, preventing blockage of the collection pipe and thus ensuring smooth wastewater discharge. When the filter screen needs to be cleaned, rotating the sliding rod will cause the limiting plate to rotate. When the limiting plate rotates to coincide with the limiting groove, the limiting plate will retract under the elastic force of the spring, releasing the limiting of the first fixed block. At this time, the first fixed block can be pulled to drive the arc plate to rotate, moving the filter screen to the outside of the collection pipe for cleaning, thus preventing blockage due to prolonged use.

Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0032] Please see Figures 1-6 This utility model provides a coding machine nozzle cleaning device, including a coding machine body 1, a cleaning component 3 and a collection component 4 on the coding machine body 1, an anti-clogging component 2 on the collection component 4, an inkjet tube 8 fixedly connected to one side of the coding machine body 1, and a printhead 5 fixedly connected to the end of the inkjet tube 8 away from the coding machine body 1.

[0033] Multiple support legs 101 are fixed on the bottom surface of the inkjet printer body 1.

[0034] Please refer to this carefully. Figure 1 and Figure 2 The cleaning assembly 3 includes a water tank 301 and a water pump 302 fixed on the upper surface of the inkjet printer body 1. The input end of the water pump 302 is connected to the water tank 301, and the output end of the water pump 302 is fixedly connected to the water outlet pipe 304.

[0035] The upper surface of the inkjet printer body 1 is fixed with a mounting base 303, and the upper surface of the mounting base 303 is fixed to the outer surface of the water pump 302.

[0036] The collection component 4 includes a collection box 403 fixed to the back of the inkjet printer body 1. A collection tube 402 is fixedly connected to one side of the collection box 403. An insertion tube 405 is inserted into the end of the collection tube 402 away from the collection box 403. A collection cylinder 401 is fixedly connected to the top of the insertion tube 405, and the collection cylinder 401 is adapted to the printhead 5.

[0037] A support plate 7 is fixed on one side of the inkjet printer body 1, and the inner wall of the hole on the support plate 7 is fixed to the outer surface of the collection tube 402.

[0038] A drain pipe 404 is fixedly connected to one side of the collection box 403, and a control valve is installed on the drain pipe 404.

[0039] When cleaning the nozzles of the nozzle 5, pull the collection cylinder 401 upward to connect the collection cylinder 401 to the nozzle 5 until the collection cylinder 401 is in tight contact with the sealing ring 6. Then, by starting the water pump 302, water can be drawn from the water tank 301 and then flowed into the interior of the nozzle 5 through the water outlet pipe 304. Finally, it flows out from the nozzle on the nozzle 5 to clean the oil stains inside the nozzle. The wastewater generated during the cleaning process passes through the collection cylinder 401, the insertion pipe 405 and the collection pipe 402 in sequence until it flows into the collection box 403 for storage and collection.

[0040] Please refer to this carefully. Figure 3 , Figure 4 , Figure 5 and Figure 6 The anti-clogging component 2 includes an installation groove 210 formed on the outer surface of the collection pipe 402 and a second fixing block 204 fixed on the outer surface of the collection pipe 402. An arc-shaped plate 201 is hinged to the inner wall of the installation groove 210 and is sealed to the installation groove 210. A filter screen 202 is fixed on one side of the arc-shaped plate 201 inside the collection pipe 402 and the outer surface of the filter screen 202 is in contact with the inner wall of the collection pipe 402. A first fixing block 203 is fixed on the outer surface of the arc-shaped plate 201 and is in contact with the second fixing block 204.

[0041] A limiting groove 206 is provided on the first fixing block 203. A sliding rod 205 is slidably connected to the inner wall of the hole on the second fixing block 204. One end of the sliding rod 205 passes through the first fixing block 203 through the limiting groove 206. A limiting plate 207 is fixed to the outer surface of the sliding rod 205 near the limiting groove 206. The limiting plate 207 intersects with the limiting groove 206. The limiting groove 206 and the limiting plate 207 are adapted to each other. A limiting block 208 is fixed to the end of the sliding rod 205 away from the limiting plate 207. A spring 209 is sleeved on the outer surface of the sliding rod 205. The spring 209 is located between the second fixing block 204 and the limiting block 208.

[0042] When wastewater generated during the cleaning of nozzle 5 passes through collection pipe 402, filter screen 202 can collect impurities in the wastewater, preventing blockage of collection pipe 402 and thus ensuring smooth wastewater discharge. When it is necessary to clean filter screen 202, rotate slide rod 205. Slide rod 205 can drive limit plate 207 to rotate. When limit plate 207 rotates to coincide with limit groove 206, limit plate 207 will retract under the elastic force of spring 209, releasing the limit on first fixed block 203. At this time, by pulling first fixed block 203, arc plate 201 can be rotated, causing filter screen 202 to move to the outside of collection pipe 402, thereby enabling cleaning and preventing blockage due to long-term use.

[0043] In use, when cleaning the nozzle of the printhead 5 is required, open the control valve on the inlet pipe 305 to inject cleaning fluid into the water tank 301, then pull the collection cylinder 401 upwards to connect it to the printhead 5 until the collection cylinder 401 is in tight contact with the sealing ring 6. Then close the control valve on the inkjet tube 8 to prevent cleaning fluid from entering the inkjet printer body 1. Next, open the control valve on the outlet pipe 304, and then start the water pump 302 to draw the cleaning fluid from the water tank 301, which then flows through the outlet pipe 304 into the printhead 5. Finally, the wastewater flows out from the nozzle on the nozzle 5, cleaning the oil stains inside the nozzle. During the cleaning process, the wastewater flows sequentially through the collection cylinder 401, the insertion pipe 405, and the collection pipe 402 until it flows into the collection box 403 for storage and collection. When the wastewater generated during the cleaning of the nozzle 5 passes through the collection pipe 402, the filter screen 202 collects impurities in the wastewater, preventing blockage and ensuring proper wastewater discharge. When the filter screen 202 needs cleaning, the sliding rod 205 is rotated, which in turn drives the limit plate 207 to rotate. When the limiting plate 207 rotates to coincide with the limiting groove 206, the limiting plate 207 will retract under the elastic force of the spring 209, releasing the limiting of the first fixing block 203. At this time, the first fixing block 203 can be pulled to drive the arc plate 201 to rotate, so that the filter screen 202 moves to the outside of the collection pipe 402, thereby cleaning it and avoiding clogging due to long-term use. After cleaning, rotate the arc plate 201 to seal it with the mounting groove 210, and the filter screen 202 enters the collection pipe 402. At this time, the first fixing block 203 and the second fixing block 204 abut against each other. Then, the sliding rod 205 drives the limiting plate 207 to move, so that the limiting plate 207 passes through the limiting groove 206. Then, the sliding rod 205 is rotated so that the limiting plate 207 intersects with the limiting groove 206. At the same time, the movement of the sliding rod 205 will drive the limiting block 208 to squeeze the spring 209, so that it generates elastic force. The elastic force can limit the position of the limiting plate 207 and the first fixing block 203, thereby limiting the arc plate 201 and preventing it from sliding.
