Technical Field

[0001] This invention relates to the field of computer technology, specifically to an anti-clogging inkjet printer and its anti-clogging mechanism for computer manufacturing and processing. Background Technology

[0002] A computer, commonly known as a PC, is a modern electronic computing machine used for high-speed calculations. It can perform numerical calculations, logical calculations, and has storage and memory functions. It is a modern intelligent electronic device that can run according to a program and automatically and quickly process massive amounts of data.

[0003] In the process of computer manufacturing, in order to facilitate subsequent maintenance personnel or organizers to understand the production date, serial number, and model information of the assembled components, an inkjet printer is used to spray characters describing the corresponding new type onto the outer surface of the corresponding component. The inkjet printer, through its connected print head, uses charged ink particles deflected under the action of a high-voltage electric field to accurately print ink onto the product surface. This type of inkjet printer used for marking computer components can be called a computer manufacturing inkjet printer.

[0004] However, the casing of existing inkjet printers is fixed with screws, making the disassembly and assembly process cumbersome when the equipment malfunctions and needs repair, thus affecting the repair efficiency of maintenance personnel. Furthermore, some existing inkjet printers that use filters to prevent ink clogging can, over time, allow impurities and ink clumps to accumulate on the filter's outer surface, causing blockages and potentially affecting ink delivery and the printing effect. Therefore, these methods do not meet the current requirements. To address this, we propose an anti-clogging inkjet printer and its anti-clogging mechanism for computer manufacturing processes.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Please see Figures 1 to 7The present invention provides an embodiment of an anti-clogging inkjet printer for computer manufacturing and processing and its anti-clogging mechanism, comprising an easily disassembleable inkjet printer 1 for computer manufacturing and processing. The easily disassembleable inkjet printer 1 includes an inkjet printer base 101, two first side panels 102, two second side panels 103, an inkjet printer top cover 104, four fixing strips 105, a U-shaped fixing groove 115, and two convenient fixing mechanisms. The two first side panels 102 are respectively mounted on the front and rear end faces of the inkjet printer base 101 via rotating shafts. The two second side panels 103 are respectively mounted on the left and right end faces of the inkjet printer base 101 via rotating shafts. The four fixing strips 105 are respectively fixed to the upper end faces of the two first side panels 102 and the two second side panels 103.

[0039] The U-shaped fixing groove 115 is located on the lower end face of the top cover 104 of the inkjet printer. All four fixing strips 105 are inserted into the U-shaped fixing groove 115. Two convenient fixing mechanisms respectively fix the two fixing strips 105 that are fixed on the upper end face of the first side panel 102 into the U-shaped fixing groove 115.

[0040] A control panel 3 is fixedly installed on one side of the outer surface of the inkjet printer 1 for easy disassembly computer manufacturing and processing. Both the inkjet printer 1 and the anti-clogging inkjet mechanism 2 are electrically connected to the control panel 3. The control panel 3 can control the inkjet printer 1 and the anti-clogging inkjet mechanism 2.

[0041] The present invention disassembles the overall shell of the inkjet printer into an inkjet printer base 101, two first side panels 102, two second side panels 103, and an inkjet printer top cover 104. The two first side panels 102 and two second side panels 103 are respectively installed on the four corners of the outer surface of the inkjet printer base 101 via a pivot. When the equipment needs to be assembled, the two first side panels 102 and two second side panels 103 are adjusted to an upright position, and the inkjet printer top cover 104 is fastened to the upper surface of the first side panels 102 and the second side panels 103.

[0042] The convenient fixing mechanism includes an electrically operated disassembly pressing cylinder 113. Below the piston rod of the electrically operated disassembly pressing cylinder 113 is a pressing plate 112 that is slidably connected to the top cover 104 of the inkjet printer. One side of the pressing plate 112 has a strip-shaped window located on the outer surface of the top cover 104 of the inkjet printer, and the pressing plate 112 communicates with the outside through the strip-shaped window. The lower end face of the pressing plate 112 is a second inclined surface 116, and below the second inclined surface 116 is a pushing block 117. The lower end face of the feed block 117 is fixed to the rectangular fixing block 107. A slot 108 is provided at the middle position of the front end face of the first rectangular fixing block 107 and the middle position of the rear end face of the second rectangular fixing block 107, from front to back. A rod 109, which is fixed to the interior of the inkjet printer top cover 104, is inserted into the slot 108. A spring 110 is sleeved on the outer surface of the rod 109, and both ends of the spring 110 are respectively connected to the rectangular fixing block 107 and the inkjet printer top cover 104. The internal components are connected; the lower side of the rear end face of the first rectangular fixing block 107 and the lower side of the front end face of the second rectangular fixing block 107 are both first inclined surfaces 111. A strip-shaped fixing groove 106 is provided on the outer side of each of the two first inclined surfaces 111. The two strip-shaped fixing grooves 106 are respectively located on the outer surface of the two fixing strips 105 fixed to the upper end face of the two first side panels 102. The rear end of the first rectangular fixing block 107 and the front end of the second rectangular fixing block 107 are respectively inserted into the interior of the two strip-shaped fixing grooves 106, and the upper end face of the rectangular fixing block 107 is in contact with the upper inner wall of the strip-shaped fixing groove 106. During the process of fastening the top cover 104 of the inkjet printer to the outer surface of the first side panel 102 and the second side panel 103, the fixing strips 105 fixed to the upper end face of the first side panel 102 and the second side panel 103 will gradually enter the interior of the U-shaped fixing groove 115 located on the lower end face of the top cover 104 of the inkjet printer.

[0043] As the fixing bar 105 descends, the upper surface of the fixing bar 105 fixed to the upper surface of the first side panel 102 will contact the first inclined surface 111 located on the outer surface of the rectangular fixing block 107, and push the rectangular fixing block 107 outward. When the rectangular fixing block 107 is pushed outward, it will compress the spring 110 connected to it.

[0044] When the upper end of the fixing strip 105 fixed to the upper end of the first side panel 102 is in contact with the inner wall of the U-shaped fixing groove 115, and the top cover 104 of the inkjet printer can no longer move downward, the rectangular fixing block 107 can be pushed inward by the reaction force of the compressed spring 110, and it is inserted into the inside of the strip-shaped fixing groove 106 fixed to the outer surface of the fixing strip 105 fixed to the upper end of the first side panel 102, thereby fixing the top cover 104 of the inkjet printer. The top cover 104 of the inkjet printer fixed to the outer surface of the four fixing strips 105 can prevent the two first side panels 102 and the second side panel 103 connected to the four fixing strips 105 from rotating on their own. After the top cover 104 of the inkjet printer is fixed, a complete inkjet printer housing can be formed.

[0045] When the inkjet printer housing needs to be disassembled, the electric disassembly cylinder 113 is activated to push the lower pressure plate 112 located below the piston rod of the electric disassembly cylinder 113 downward. As the lower pressure plate 112 descends, the U-shaped fixing groove 115 located on the lower end face of the lower pressure plate 112 will contact the push block 117 fixed to the upper end face of the rectangular fixing block 107, and push the rectangular fixing block 107 and the push block 117 together outward. When the rectangular fixing block 107 has completely left the inside of the strip fixing groove 106, the fixing of the inkjet printer top cover 104 is released. After removing the top cover 104 of the inkjet printer, the first side panel 102 and the second side panel 103 can be rotated through the pivot between the inkjet printer base 101 and the first side panel 102 and the second side panel 103 to adjust them to a parallel state. This will expose the components installed inside the inkjet printer 1 for easy disassembly computer production and processing to the outside. The above technical solution allows for the quick disassembly of the inkjet printer base 101, thereby improving the convenience for maintenance personnel when performing maintenance on the inkjet printer 1 for easy disassembly computer production and processing.

[0046] If the lowering cylinder 113 malfunctions and cannot automatically push the lowering plate 112 downward, the disassembly personnel can access the lowering plate 112 through the strip window and manually push it downward to disassemble the inkjet printer 1 for easy disassembly of computer manufacturing. The above technical solution can prevent the situation where the lowering cylinder 113 malfunctions and the inkjet printer 1 for easy disassembly of computer manufacturing cannot be disassembled.

[0047] An anti-clogging coding mechanism 2 is fixedly installed inside the inkjet printer 1 for easy disassembly computer manufacturing. The anti-clogging coding mechanism 2 includes an ink cartridge 203, an ink collection tank 207, multiple annular grinding grooves 208, grinding rings 212 in the same number as the annular grinding grooves 208, a filter screen 227, multiple filter holes 231, anti-clogging and unblocking rods 224 in the same number as the filter holes 231, two semi-circular pressure plates 220, and a synchronous drive mechanism. The ink collection tank 207 is located inside the ink cartridge 203. The multiple annular grinding grooves 208 are arranged from top to bottom on the lower side of the inner wall of the ink collection tank 207. The multiple grinding rings 212 are located inside the multiple annular grinding grooves 208 respectively.

[0048] The filter screen 227 is located below the ink collection tank 207, and multiple filter holes 231 are arranged in a circular pattern on the upper surface of the filter screen 227.

[0049] Two semi-circular pressure plates 220 are located on both sides above the filter screen 227. Multiple anti-clogging and unblocking rods 224 are fixed to the lower end face of the two semi-circular pressure plates 220, and the positions of the multiple anti-clogging and unblocking rods 224 correspond to the positions of multiple filter through holes 231. The synchronous drive mechanism can push the two semi-circular pressure plates 220 downward in a cyclic manner while synchronously driving all grinding rings 212 to rotate.

[0050] A cabinet door 114 is installed in the middle of the outer surface of the second side panel 103 near the control panel 3, and the second side panel 103 and the cabinet door 114 are connected by a pivot. The outer surface of the top end of the ink cartridge 203 is covered with a sealing cover 204. When the equipment needs to be used, open the cabinet door 114, remove the sealing cover 204, add ink into the ink storage tank 207, and after the ink is added, close the sealing cover 204 and close the cabinet door 114.

[0051] The synchronous drive mechanism includes a motor mounting housing 205. A support bracket 206 is fixedly installed at each of the four corners of the outer surface of the top end of the motor mounting housing 205, and the other end of the support bracket 206 is fixed to the inner wall of the ink cartridge 203. A stepper motor 209 is fixedly installed inside the motor mounting housing 205. The output shaft of the stepper motor 209 is connected to a transmission shaft 210 via a coupling. A planar conical drive block 211 is fixedly connected to the lower end face of the transmission shaft 210, and multiple grinding rings 212 are fixedly sleeved on the outer surface of the planar conical drive block 211. When the cabinet door 114 is... After closing, the stepper motor 209 is started. The stepper motor 209 drives the planar conical drive block 211 connected to it via the transmission shaft 210 to rotate. The rotating planar conical drive block 211 drives the grinding ring 212 fixed on the outer surface of the planar conical drive block 211 to rotate. The rotating grinding ring 212 can perform grinding work on the ink added to the ink collection tank 207 and flowing downward. The above technical solution can improve the uniformity and fineness of the ink, thereby improving the clarity and fineness of the printing, and at the same time reducing the risk of clogging of the filter screen 227 used for filtration.

[0052] The four support brackets 206 fixed to the outer surface of the motor housing 205 can prevent the stepper motor 209 from rotating on its own due to its own driving force, which would prevent the planar conical drive block 211 from rotating.

[0053] A first gear 213 is fixedly sleeved on the lower side of the outer surface of the motor mounting housing 205. The first gear 213 meshes with a second gear 214. The axis of the second gear 214 is connected to a gear shaft 215 that is vertically inserted into the interior of the planar conical drive block 211. The gear shaft 215 and the planar conical drive block 211 are connected by a roller bearing. During the rotation of the planar conical drive block 211, the gear shaft 215 connected to it will revolve around the center point of the lower end face of the motor mounting housing 205. As the gear shaft 215 revolves, the second gear 214 fixed to the upper end face of the gear shaft 215 will roll along the first gear 213 fixed to the lower side of the outer surface of the motor mounting housing 205. Under the transmission of the gear structure, the second gear 214 rolling along the outer surface of the first gear 213 will rotate synchronously. The rotating second gear 214 can drive the gear shaft 215 connected to the axis of the second gear 214 to rotate.

[0054] A first bevel gear 216 is fixedly sleeved on the lower side of the outer surface of the gear shaft 215. The first bevel gear 216 meshes with a second bevel gear 217. The shaft of the second bevel gear 217 is connected to a lower pressure rod 218. Both sides of the outer surface of the lower pressure rod 218 are concave grooves 230. A metal sleeve 219 is movably sleeved at the middle position of the outer surface of the concave groove 230, and the two metal sleeves 219 are respectively located above the two semi-circular lower pressure plates 220. The rotating gear shaft 215 can drive The first bevel gear 216, which is fixedly sleeved on the lower side of the outer surface of the gear shaft 215, and the second bevel gear 217, which meshes with the first bevel gear 216, rotate together. The rotating second bevel gear 217 can drive the lower pressure rod 218 connected to the shaft of the second bevel gear 217 to rotate. When the lower pressure rod 218 rotates, the metal sleeves 219, which are movably sleeved on the concave grooves 230 on the outer surface of the lower pressure rod 218, will revolve around the front end of the lower pressure rod 218.

[0055] A metal sleeve 221 is provided above the front end of the first semi-circular lower pressure plate 220 and above the rear end of the second semi-circular lower pressure plate 220, from front to back. A guide rod 222 is axially connected to the metal sleeve 221. The two guide rods 222 vertically move through the two semi-circular lower pressure plates 220 respectively. A return spring 223 is sleeved on the outer surface of the guide rod 222, and the upper and lower end faces of the return spring 223 are connected to the lower end face of the semi-circular lower pressure plate 220 and the planar conical drive block 211, respectively. The revolving metal sleeve 219 will contact the semi-circular lower pressure plate 220 located below it and press the semi-circular lower pressure plate 220... As the pressure plate 220 is pushed downwards, the anti-clogging and unblocking rod 224 fixed to the lower end face of the semi-circular lower pressure plate 220 will be inserted into the filter through hole 231 located on the upper end face of the filter screen 227 to clean the impurities and blockages stuck inside the filter through hole 231, ensuring that the filter through hole 231 is unobstructed. The above technical solution can prevent the filter through hole 231 located on the outer surface of the filter screen 227 from becoming clogged during long-term use of the filter screen 227, thereby ensuring the coating quality of the inkjet printer with the anti-clogging structure under long-term use.

[0056] When the semi-circular lower pressure plate 220 is pushed downward, it will compress the reset spring 223 connected to it. After the metal sleeve 219 rolls over the upper end face of the semi-circular lower pressure plate 220, the reaction force of the compressed reset spring 223 can push the semi-circular lower pressure plate 220 and the anti-clogging and unblocking rod 224 fixed to the lower end face of the semi-circular lower pressure plate 220 back to their original positions, thereby opening the filter through hole 231.

[0057] The anti-clogging inkjet printing mechanism 2 also includes a small water pump 229 for conveying. A return push plate 225 is installed on the upper end face of the small water pump 229. An ink inlet 226 is provided in the middle position of the upper end face of the return push plate 225, and a filter screen 227 is fixed inside the ink inlet 226.

[0058] A small water pump 229 for conveying ink is fixedly connected to the lower side of its front end, and the other end of the ink pump 202 is connected to the spray nozzle 201. When the stepper motor 209 is started, the small water pump 229 for conveying ink is started to draw the ground and filtered ink and deliver it to the inside of the spray nozzle 201 through the ink pump 202, thereby providing raw materials for the spraying operation of the spray nozzle 201.

[0059] On both sides below the return push plate 225, there is a single-cylinder cylinder 228 for pushing upward, which is fixedly installed inside the ink cartridge 203. The shape of the upper end face of the return push plate 225 is consistent with the shape of the lower end face of the planar conical drive block 211. When it is necessary to temporarily shut down the equipment, the single-cylinder cylinder 228 is activated to push the return push plate 225 connected to it upward. As the return push plate 225 rises, the ink that has been ground between the return push plate 225 and the planar conical drive block 211 will be pushed to the grinding ring 212 and the annular grinding groove 208. Through the above technical solution, the ink that has been ground but will not be used for a period of time can be pushed back to the grinding area. This prevents the ground ink from clumping together during long-term shutdown of the equipment, which would not be able to be ground again and would eventually cause the filter through hole 231 to be blocked by the clumped ink.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
