Description

Technical Field

[0001] The present invention relates to the technical field of printers, in particular to a printer which is convenient for replacing ink. Background Art

[0002] Printers are widely used in homes, business offices, and the photography industry. The miniaturization and portability of printers are becoming more and more popular among consumers.

[0003] There are many existing technologies for printer devices, such as: Chinese Patent Publication No. CN114013184A discloses a printer that is convenient for replacing ink; the patent drives the moving plate to slide on the surface of the slide rod to squeeze the reset spring, so that the card block and the card slot are disengaged and fixed, and the ink cartridge body is pulled out by a handle for disassembly. When installing, the above movement process moves in the opposite direction, thereby avoiding the trouble of replacing ink, requiring the use of tools to remove the ink cartridge containing ink, which is time-consuming and labor-intensive, and the ink cartridge is not firmly fixed, thereby improving convenience; the invention starts the motor, the motor drives the gear to rotate, the gear is engaged with the gear rod, and drives the shell and the sliding block to slide on the slide rail frame; rotates the control screen, the control screen drives the second rotating seat to rotate, and the rotating threaded rod drives the extrusion limit strip to fix the second rotating seat and the first rotating seat, thereby avoiding long-term use causing discomfort in the use angle and position, and the operation is more tiring, increasing the fatigue of the operator, and improving the adjustability.

[0004] However, there are still some problems in actual use: 1. In the actual use of traditional printers, the end cap design of the ink cartridge has certain defects and is easy to be accidentally opened. This may cause unauthorized personnel to extract the ink cartridge at will. Once the ink cartridge is improperly extracted, it will seriously affect the normal use of the printer and may even damage the internal structure of the printer; 2. When replacing the printer ink cartridge, the ink port is often in an open state. In this case, external dust can easily fall into the ink port. After the dust enters the ink port, it may mix with the ink, thus affecting the printing effect. Specifically, the printed document may appear blurry, inaccurate in color, unclear lines, etc. In addition, long-term accumulation of dust may clog the ink port, further reducing the printing quality, or even damaging the printer's print head.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. In the printer which is convenient for replacing ink, the first screw is driven to rotate by the output shaft of the servo motor, so that the placement plate moves horizontally, and at the same time, the ink box clamped at the end of the ink port is driven away from the inside of the fixed frame. When the placement plate moves, the inner wall of the partition is pushed to make the partition rotate on the surface of the fixed rod, so that the end of the fixed frame is in an open state. When the placement plate moves, the rack is driven to move, and when the rack moves, the rotating gear is driven to rotate in the opposite direction. The winding roller provided on the surface of the rotating gear moves coaxially, and the pull rope wrapped around the surface of the winding roller is loosened. The moving rod is pushed by the reverse force of the reset spring to move the sealing plates relative to each other. Since the ends of the sealing plates are adapted to each other, the ends of the sealing plates can be sealed when they are fitted, thereby preventing external dust from floating into the ink port and affecting the printing effect when the partition is opened.

[0018] 2. In the printer which is convenient for replacing ink, the ink cartridge is pushed to move on the surface of the roller rod. During the movement of the ink cartridge, the limit block is adapted to the limit groove provided at the end of the clamping plate. At the same time, during the movement of the ink cartridge, the clamping plate is squeezed so that the slide bar provided at the end of the clamping plate slides on the inner wall of the cylinder and squeezes the compression spring, so that the diameter between the clamping plates increases, which is convenient for adjusting the position of the ink cartridge. When the pressure on the clamping plate stops, the compression spring resets and applies a reverse force to the slide bar, so that the clamping plate at the end of the slide bar clamps and limits the side wall of the ink cartridge, thereby facilitating the rapid adjustment of the installation position of the ink cartridge and improving the efficiency of ink replacement.

[0019] 3. In the printer which is convenient for replacing ink, when the limit block on the side wall of the ink cartridge is clamped on the inner wall of the limit groove, the clamping plate is subjected to the reverse force of the compression spring to squeeze and limit the ink cartridge. When the clamping plate has completed limiting the ink cartridge, the output end of the rotating motor is controlled to drive the second screw rod to rotate, and the toothed plates provided on both sides of the surface of the second screw rod move relatively to clamp and fix the tooth block, thereby preventing the ink cartridge from sliding in the opposite direction due to resistance when it is moved to the end of the ink port for adaptation, thereby facilitating the rapid installation and adaptation of the ink cartridge.

[0024] The purpose of this embodiment is to provide a printer that is easy to replace ink. Figure 1-Figure 8 As shown, the machine body 100 and the ink port 104 are included. A fixing frame 101 is provided on the side wall of the machine body 100. A fixing rod is provided at the end of the fixing frame 101. A partition 102 is rotatably provided on the surface of the fixing rod. A torsion spring 103 is provided on the surface of the fixing rod. The two ends of the torsion spring 103 are respectively connected to the fixing frame 101 and the partition 102. A moving component 300 is provided inside the fixing frame 101. The surface of the moving component 300 is used to place the ink cartridge 200. Limiting blocks 201 are provided on both sides of the surface of the ink cartridge 200. The moving component 300 is pushed when the ink cartridge 200 needs to be replaced. The partition 102 is opened, and clamping assemblies 400 are provided on both sides of the surface of the movable assembly 300. The clamping assemblies 400 are used to limit and fix the ink cartridge 200 placed on the surface of the movable assembly 300. The movable assembly 300 drives the ink cartridge 200 to move to the ink port 104 for plugging and adaptation. An opening and closing assembly 500 is provided at the end of the ink port 104. The opening and closing assembly 500 closes the end of the ink port 104 when the ink cartridge 200 is replaced, and the opening and closing assembly 500 automatically opens when the new ink cartridge 200 is moved to the ink port 104.

[0025] When the printer is in use, in order to prevent unauthorized personnel from arbitrarily opening the partition 102 to take out the ink cartridge 200 and affecting the normal use of the printer, the moving assembly 300 includes a servo motor 301 arranged inside the body 100, a first screw rod 302 is arranged at the output end of the servo motor 301, a placement plate 303 is arranged on the surface of the first screw rod 302, and the placement plate 303 is driven to reciprocate horizontally when the first screw rod 302 moves, a fixing rod is arranged at the end of the fixed frame 101, a partition 102 is rotatably arranged on the surface of the fixing rod, a torsion spring 103 is arranged on the surface of the fixing rod, and the two ends of the torsion spring 103 are respectively connected to the fixed frame 101 and the partition 102. The surface of the partition 102 is smooth, so it is not easy for unauthorized personnel to open the partition 102, thereby preventing the ink cartridge 200 from being taken out and affecting the use of the machine body 100. When the ink cartridge 200 needs to be replaced, the output shaft of the servo motor 301 is controlled to drive the first screw rod 302 to rotate. When the first screw rod 302 rotates, the placement plate 303 on its surface moves in a horizontal direction. The placement plate 303 pushes the inner wall of the partition 102 during the movement, so that the partition 102 is opened during the movement of the placement plate 303, thereby preventing unauthorized personnel from arbitrarily opening the partition 102 and taking out the ink cartridge 200, thereby ensuring the normal use of the device.

[0026] Taking into account that the ink cartridge 200 is heavy, it is not easy for a child to push the ink cartridge 200 to the engaging position when replacing it. Therefore, a roller rod 305 is provided on the surface of the placement plate 303. When the ink cartridge 200 is placed on the surface of the roller rod 305, it is convenient to quickly push it to the center of the placement plate 303. The side walls of the placement plate 303 are provided with racks 304. An opening and closing assembly 500 is provided on one side of the rack 304. By providing the roller rod 305 on the surface of the placement plate 303, the ink cartridge 200 is placed on the surface of the roller rod 305. Since the friction between the roller rod 305 and the ink cartridge 200 is reduced, it is convenient to push the ink cartridge 200 to the engaging position for installation.

[0027] When the ink cartridge 200 is placed on the surface of the placement plate 303, in order to facilitate quick adaptation to the end of the ink port 104, the position of the ink cartridge 200 needs to be adjusted to make it in the center, which usually requires multiple adjustments, resulting in low ink replacement efficiency. Therefore, the clamping assembly 400 includes a cylinder 401 arranged on the side wall of the placement plate 303, a slide bar 402 is slidably provided on the inner wall of the cylinder 401, a compression spring 403 is provided between the cylinder 401 and the slide bar 402, a clamping plate 404 is provided at the end of the slide bar 402, and the clamping plate 404 is used to clamp and limit the ink cartridge 200 placed on the surface of the roller rod 305, a limiting groove 406 is provided on the surface of the clamping plate 404, and the limiting groove 406 is adapted to the limiting block 201, and the limiting block 201 slides on the inner wall of the clamping plate 404, and a tooth block 405 is provided at the end of the slide bar 402, and the tooth block 405 penetrates the cylinder 401 and slides on the cylinder 4 01 outside, when placing the ink cartridge 200, by pushing the ink cartridge 200 to move on the surface of the roller rod 305, the limit block 201 is adapted to the limit groove 406 provided at the end of the clamping plate 404 during the movement of the ink cartridge 200, and at the same time, by squeezing the clamping plate 404 during the movement of the ink cartridge 200, the slide bar 402 provided at the end of the clamping plate 404 slides on the inner wall of the cylinder 401 and squeezes the compression spring 403, so that the diameter between the clamping plates 404 increases, which is convenient for adjusting the position of the ink cartridge 200. When the ink cartridge 200 is placed, when the pressure on the clamping plate 404 stops, the compression spring 403 resets and applies a reverse force to the slide bar 402, so that the clamping plate 404 at the end of the slide bar 402 clamps and limits the side wall of the ink cartridge 200, thereby facilitating the rapid adjustment of the installation position of the ink cartridge 200 and improving the efficiency of ink replacement. When the ink cartridge 200 moves to the end of the ink port 104, it is necessary to continue to move the ink cartridge 200 so that its end is inserted into the ink port 104 for adaptation. During the process of inserting the ink cartridge 200 into the ink port 104, the end of the ink cartridge 200 encounters greater resistance, which causes the ink cartridge 200 clamped on the inner wall of the clamping plate 404 to slide in the opposite direction, resulting in failure of the adaptation of the ink cartridge 200 and the ink port 104. Therefore, extension plates 407 are provided on both sides of the inner wall of the placement plate 303, and a rotating motor 408 is provided on the top of the extension plate 407. The output shaft of the rotating motor 408 passes through the extension plate 407 and a second screw rod 409 is provided at the end. The thread on the surface of the second screw rod 409 is symmetrical, and toothed plates 410 are provided on both sides of the surface of the second screw rod 409. When the toothed plate 410 moves relatively, the tooth block 405 is fixed. When the limit block 201 on the side wall of the ink cartridge 200 is clamped on the inner wall of the limit groove 406, the clamping plate 404 is subjected to the reverse force of the compression spring 403 to squeeze and limit the ink cartridge 200. When the clamping plate 404 completes the limitation of the ink cartridge 200, the output end of the control motor 408 drives the second screw rod 409 to rotate. When the second screw rod 409 rotates, the surface threads thereof are symmetrical. Therefore, the toothed plates 410 provided on both sides of the surface of the second screw rod 409 move relatively to clamp and fix the tooth block 405, thereby preventing the ink cartridge 200 from sliding in the opposite direction due to resistance when it moves to the end of the ink port 104 for adaptation, thereby improving the success rate of ink replacement adaptation.

[0028] Considering that when the ink cartridge 200 is replaced, since the partition 102 is opened, external dust can easily enter the ink port 104 from the partition 102, affecting the subsequent printing quality, therefore, the opening and closing component 500 includes a hollow column 501 arranged on both sides of the ink port 104, a moving rod 502 is slidably provided on the inner wall of the hollow column 501, a return spring 503 is provided between the hollow column 501 and the moving rod 502, and a sealing plate 504 is provided at the end of the moving rod 502. In a natural state, the end of the sealing plate 504 is fitted to seal the opening of the ink port 104, and rotating gears 505 are provided on both sides of the inner wall of the fixed frame 101. When the placement plate 303 drives the rack 304 to move, the rack 304 drives the rotating gear 505 to mesh and rotate. A winding roller 506 is provided on the top of the wheel 505, and a pull rope 507 is provided between the winding roller 506 and the moving rod 502. When the placement plate 303 moves close to the ink port 104, the rack 304 drives the rotating gear 505 to rotate, and the winding roller 506 provided on the surface of the rotating gear 505 stretches the pull rope 507. A fixed pulley 508 is provided on one side of the hollow column 501. When the pull rope 507 moves, it fits the surface of the fixed pulley 508. When the ink cartridge 200 is replaced, the output shaft of the servo motor 301 drives the first screw rod 302 to rotate, so that the placement plate 303 moves horizontally, and at the same time drives the ink cartridge 200 clamped at the end of the ink port 104 away from the inside of the fixed frame 101. When the placement plate 303 moves, it pushes the inner wall of the partition 102 so that the partition 102 rotates on the surface of the fixed rod, so that the fixed frame 101 is in an open state. When the placement plate 303 moves, it drives the rack 304 to move. When the rack 304 moves, it drives the rotating gear 505 to rotate in the opposite direction. The winding roller 506 provided on the surface of the rotating gear 505 moves coaxially. Therefore, the pull rope 507 wound on the surface of the winding roller 506 is loosened, and the moving rod 502 is pushed by the reverse force of the return spring 503 to move relative to each other. Since the ends of the sealing plates 504 are adapted to each other, the ends of the sealing plates 504 can seal the ends of the ink port 104 when they are fitted, so that when the partition 102 is opened, external dust floats into the ink port 104 and affects the later printing effect. When the ink cartridge 200 is replaced, it is placed on the roller rod 30 5, the ink cartridge 200 is automatically clamped and fixed by the clamping plate 404, and the output shaft of the servo motor 301 is controlled to rotate in the opposite direction, so that the placement plate 303 provided on the surface of the first screw rod 302 is close to the end of the ink port 104. When the placement plate 303 drives the rack 304 to approach the ink port 104, the rack 304 drives the rotating gear 505 to rotate in the opposite direction, and the winding roller 506 provided on the top of the rotating gear 505 winds the pull rope 507. The pull rope 507 is attached to the surface of the fixed pulley 508 and is wound around the end of the winding roller 506, so that the sealing plate 504 is opened, so that the ink cartridge 200 is adapted to the ink port 104, thereby preventing the ink port 104 from being contaminated by external dust during the replacement of the ink cartridge 200.

[0029] The sealing plate 504 is used to block external dust. Dust is easy to fall onto the surface of the sealing plate 504. When a lot of dust is accumulated, it is easy to float inside the machine body 100, affecting the service life of the machine body 100. Therefore, a rubber roller 105 is provided at the end of the sealing plate 504. When the sealing plate 504 moves, it adheres to the surface of the rubber roller 105. The rubber roller 105 rotates on the surface of the sealing plate 504 due to the friction force and adheres to the dust on the surface. When the sealing plate 504 is in the process of opening and closing, the rubber roller 105 always adheres to the surface of the sealing plate 504 to adhere and collect the dust attached to the surface, thereby preventing the dust from floating and causing the internal circuit of the machine body 100 to be broken, thereby improving the service life of the machine body 100. When the ink cartridge 200 needs to be replaced, the output shaft of the servo motor 301 drives the first screw rod 302 to rotate, so that the placement plate 303 moves horizontally, and at the same time drives the ink cartridge 200 connected to the end of the ink port 104 away from the interior of the fixed frame 101. When the placement plate 303 moves, it pushes the inner wall of the partition 102, so that the partition 102 rotates on the surface of the fixed rod, so that the end of the fixed frame 101 is in an open state. When the placement plate 303 moves, it drives the rack 304 to move. The rotating gear 505 rotates in the opposite direction, and the winding roller 506 provided on the surface of the rotating gear 505 moves coaxially. Therefore, the pull rope 507 wound on the surface of the winding roller 506 is loosened, and the moving rod 502 is pushed by the reverse force of the return spring 503 to push the sealing plates 504 to move relatively. Since the ends of the sealing plates 504 are adapted to each other, the ends of the sealing plates 504 can seal the ends of the ink ports 104 when they are fitted, thereby preventing external dust from floating into the ink ports 104 and affecting the printing effect when the partition 102 is opened; When the ink cartridge 200 is replaced and placed on the surface of the roller rod 305, the ink cartridge 200 is pushed to move on the surface of the roller rod 305. During the movement of the ink cartridge 200, the limit block 201 is adapted to the limit groove 406 provided at the end of the clamping plate 404. At the same time, during the movement of the ink cartridge 200, the clamping plate 404 is squeezed to make the slide bar 402 provided at the end of the clamping plate 404 slide on the inner wall of the cylinder 401 and squeeze the compression spring 403, so that the diameter between the clamping plates 404 increases, which is convenient for adjusting the position of the ink cartridge 200. When the pressure on the clamping plate 404 stops, the compression spring 403 resets and applies a reverse force to the slide bar 402, so that the clamping plate 404 at the end of the slide bar 402 clamps and limits the side wall of the ink cartridge 200, thereby facilitating the rapid adjustment of the installation position of the ink cartridge 200 and improving the efficiency of ink replacement. When the limit block 201 on the side wall of the ink cartridge 200 is clamped on the inner wall of the limit groove 406, the clamp plate 404 is squeezed and limited by the reverse force of the compression spring 403. When the clamp plate 404 completes the limitation of the ink cartridge 200, the output end of the control motor 408 drives the second screw rod 409 to rotate. When the second screw rod 409 rotates, since the surface thread is symmetrical, the toothed plates 410 on both sides of the surface of the second screw rod 409 move relatively to clamp and fix the tooth block 405, thereby preventing the ink cartridge 200 from sliding in the opposite direction due to resistance when it moves to the end of the ink port 104 for adaptation, thereby facilitating the rapid installation and adaptation of the ink cartridge 200.
