Description

Technical Field

[0001] The invention relates to the technical field of inkjet printing auxiliary equipment, and in particular to an ink recovery device for an inkjet printer. Background Art

[0002] In the cable industry, due to the wide variety of products, including cables from different manufacturers, different models, and different uses, clear and durable markings are required on the surface of the products for easy distinction and tracking. These markings usually contain information such as the manufacturer's name, product model, specifications, certification marks, production date, batch number, etc. The development of inkjet printer technology has provided an efficient marking solution for the cable industry. Inkjet printers can quickly and accurately print text, graphics, barcodes and other information on the surface of cables of various materials. Inkjet printers mainly use continuous inkjet technology. With the advancement of technology, drop-on-demand (DOD) inkjet technology and laser inkjet technology have emerged, but they are relatively expensive.

[0003] When inkjetting cables, cable guide transmission mechanisms are usually set on both sides of the printer to straighten the cables for inkjetting and to facilitate the transmission of the cables to the next work section. However, if some existing inkjet printers do not spray ink continuously and stop spraying ink for a long time, the ink at the nozzle will easily clog the nozzle. Therefore, the nozzle is intermittently sprayed to prevent clogging. However, when this method is used, when the cable is not sprayed, the ink drips on the ground and is difficult to clean, resulting in a waste of ink. Summary of the invention

[0004] In view of the deficiencies in the prior art, the technical problem solved by the present invention is to provide an ink recovery device for an inkjet printer, which solves the problem that the prior inkjet printer sprays ink intermittently, and when not processed, the ink drips onto the ground and is difficult to clean, resulting in a waste of ink.

[0005] In order to solve the above problems, the technical solution adopted by the present invention is: an ink recovery device for an inkjet printer, comprising an inkjet printer, a nozzle and a mounting frame arranged in a vertical direction, the nozzle is connected to the inkjet printer through a flexible hose, the nozzle and the mounting frame are detachably connected, the nozzle outlet end is arranged vertically downward, and an ink collecting mechanism is provided at the lower end of the nozzle, the ink collecting mechanism is detachably connected to the mounting frame, the ink collecting mechanism comprises a receiving hopper and an ink storage tank connected in sequence from top to bottom, and the cable passes through the space between the hopper and the nozzle.

[0006] The beneficial effects of this solution are: by setting up an ink collection mechanism, when the cable is not being coded, the ink sprayed from the nozzle flows into the hopper, and then flows into the ink storage tank through the hopper, thereby realizing ink recovery; preventing ink from dripping onto the ground and causing pollution, which is difficult to clean; and also avoiding ink waste and reducing production costs.

[0007] Furthermore, the mounting frame is connected to the nozzle through a clamp. The bolt can be loosened, and then the clamp can be loosened to adjust the height of the nozzle. After the inkjet printing is completed, the nozzle is placed close to the hopper to prevent the nozzle from being too far away from the hopper, causing ink to splash outside the hopper and contaminate the ground and surrounding equipment.

[0008] Furthermore, a height adjustment mechanism is also provided on one side of the mounting frame, and the height adjustment mechanism includes a reciprocating screw arranged in a vertical direction, the rod body of the reciprocating screw is threadedly connected to a slider, one end of the reciprocating screw is fixedly connected to a fixed rod, one end of the fixed rod is connected to a motor, the reciprocating screw is parallel to the mounting frame, the nozzle is slidably connected to the mounting frame ring, and the ring is detachably connected to the slider through a connecting rod.

[0009] The height of the print head is adjusted by means of a motor and a screw rod, which makes the adjustment more convenient. After the coding is completed, the height adjustment mechanism makes the print head close to the receiving hopper to prevent the print head from being too far away from the receiving hopper, causing ink to splash outside the hopper and pollute the ground and surrounding equipment. When coding is required, the print head is kept at a suitable distance from the cable to ensure the coding effect.

[0010] Furthermore, the motor is electrically connected to a photoelectric switch, which includes a light receiver and a light transmitter. The light receiver is detachably fixed on a mounting frame, and the mounting frame is detachably fixed with a bracket. The light transmitter is installed on the bracket and parallel to the light receiver. When the nozzle prints the code on the cable, the cable can block the light path emitted by the light transmitter, and the light receiver controls the opening and closing of the motor according to the received light intensity value.

[0011] The photoelectric switch detects whether there is a cable passing through. When there is no cable, the photoelectric switch controls the motor to rotate, so that the slider moves to the lower stop position; then the connecting rod drives the nozzle to move downward to the lower stop position, so that the nozzle is close to the hopper to prevent the nozzle from being too far away from the hopper, causing ink to splash outside the hopper; when there is a cable, the photoelectric switch controls the motor to rotate, so that the slider moves to the upper stop position; so that the nozzle and the cable maintain a suitable distance to ensure the coding effect. No manual operation is required, and automatic nozzle height adaptability adjustment is achieved.

[0012] Furthermore, a top block is sleeved on the top of the mounting frame, and the upper end surface of the top block is a downwardly concave arc groove, and the flexible hose is connected to the spray head after passing through the arc groove. The arc groove plays a role of limiting support for the flexible hose.

[0013] Furthermore, a support plate is provided at the lower end of the ink storage tank, the support plate is connected to the mounting frame through a clamp, the hopper is connected to the mounting frame through a clamp, and the lower end of the hopper is threadedly connected to the upper end of the ink storage tank. By providing the support plate to support the ink storage tank, the supporting pressure of the hopper on the ink storage tank is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is further described in detail through specific implementation methods:

[0018] The figure marks in the drawings of the specification include: mounting frame 1, top block 11, support plate 12, hopper 13, ink storage tank 14, inkjet printer 2, nozzle 21, flexible hose 22, reciprocating screw 3, motor 31, fixed rod 32, slider 33, connecting rod 34, collar 35, switch 36, light receiver 4, light transmitter 41, bracket 42, cable 5, transmission mechanism 6.

[0019] Embodiment 1 is basically as attached Figure 1 As shown: an ink recovery device for an inkjet printer 2, comprising an inkjet printer 2, a nozzle 21 and a mounting frame 1 arranged in a vertical direction, the mounting frame being located between two transmission mechanisms 6, the nozzle 21 being connected to the inkjet printer 2 via a flexible hose 22, the nozzle 21 being connected to the mounting frame 1 via a clamp, the outlet end of the nozzle 21 being arranged vertically downward, and an ink collecting mechanism being provided at the lower end of the nozzle 21, the ink collecting mechanism being detachably connected to the mounting frame 1, the ink collecting mechanism comprising a receiving hopper 13 and an ink storage tank 14 connected in sequence from top to bottom, and a cable 5 passing through the space between the hopper 13 and the nozzle 21.

[0020] A top block 11 is sleeved on the top of the mounting frame 1, and the upper end surface of the top block 11 is a downwardly concave arc groove. The flexible hose 22 passes through the arc groove and is connected to the nozzle 21, and the arc groove plays a role of limiting support for the flexible hose 22; a support plate 12 is provided at the lower end of the ink storage tank 14, and the support plate 12 is connected to the mounting frame 1 through a clamp, and the hopper 13 is connected to the mounting frame 1 through a clamp, and the ink storage tank 14 is supported by providing the support plate 12 to reduce the supporting pressure of the hopper 13 on the ink storage tank 14; the lower end of the hopper 13 is threadedly connected to the upper end of the ink storage tank, and the threaded connection is convenient for disassembly.

[0021] By setting up an ink collection mechanism, when the cable 5 is not being coded, the ink sprayed from the nozzle 21 flows into the hopper 13, and then flows into the ink storage tank 14 through the hopper 13, thereby realizing ink recovery; preventing ink from dripping onto the ground and causing pollution, which is difficult to clean; and also avoiding ink waste, thereby reducing production costs. The nozzle 21 is connected to the mounting frame 1 through a clamp, and the bolts can be loosened, and then the clamp is loosened to adjust the height of the nozzle 21. After the coding is completed, the nozzle 21 is brought close to the hopper 13 to prevent the nozzle 21 from being too far away from the hopper 13, causing ink to splash outside the hopper 13 and pollute the ground and surrounding equipment.

[0022] Embodiment 2 is basically as attached Figure 2 As shown, the same parts as those in Example 1 are not described again, except that: a height adjustment mechanism is also provided on one side of the mounting frame 1, and the height adjustment mechanism includes a screw rod arranged in the vertical direction, the screw rod body is threadedly connected with a slider 33, one end of the screw rod is connected with a motor 31, the screw rod is parallel to the mounting frame 1, the nozzle 21 is slidably connected with a collar 35 of the mounting frame 1, a connecting rod 34 is provided between the collar 35 and the slider 33, and the connecting rod 34 is respectively engaged with the collar 35 and the slider 33. A switch 36 is fixedly bonded to the mounting frame 1, and the switch 36 is electrically connected to the motor 31; the screw rod adopts a reciprocating screw rod 3, one end of the reciprocating screw rod is welded with a fixed rod 32, and one end of the fixed rod 32 is engaged with the motor output shaft. The reciprocating screw rod 3 is selected, and when the reciprocating screw rod 3 drives the slider 33 to rotate to the lower stop position, the screw rod is continuously rotated to reversely drive the slider 33 upward to move to the upper stop position, and thus reciprocates in the vertical direction, so that there is no need to control the motor 31 to change the rotation direction to control the moving direction of the slider 33.

[0023] When the cable 5 is sprayed with code, the operator presses the switch 36 to start the motor 31. The rotation of the motor 31 drives the reciprocating screw 3 to rotate, thereby driving the sliding movement. When the slider 33 moves downward to a suitable position close to the hopper 13, the operator presses the switch 36 to turn off the motor 31. When the cable 5 needs to be sprayed with code again, the operator presses the switch 36 to start the motor 31. The rotation of the motor 31 drives the reciprocating screw 3 to rotate, thereby driving the sliding movement. When the slider 33 moves upward to a suitable height, the operator presses the switch 36 to turn off the motor 31.

[0024] After the coding is completed, the height adjustment mechanism allows the nozzle 21 to be close to the hopper 13 to prevent the nozzle 21 from being too far away from the hopper 13, causing ink to splash outside the hopper 13 and pollute the ground and surrounding equipment; when coding is required, the nozzle 21 is kept at a suitable distance from the cable 5 to ensure the coding effect.

[0025] Embodiment 3 is basically as attached Figure 3As shown, the similarities with Example 1 and Example 2 are not repeated here. The difference lies in that the motor 31 is electrically connected to the photoelectric switch 36, and the photoelectric switch 36 model is a through-type photoelectric switch 36 of E3T-SL11 and E3S-DS10E4; the photoelectric switch 36 includes a light receiver 4 and a light emitter 41, and the light emitter 41 uses red light for easy identification; the light receiver 4 is bolted to the mounting frame 1, and the mounting frame 1 is bolted to a bracket 42, and the bracket 42 is L-shaped, including a horizontal plate and a vertical plate, and the vertical plate has an opening for the ink of the nozzle 21 to pass through, and the light emitter 41 is installed on the vertical plate and parallel to the light receiver 4. When the nozzle 21 performs inkjet printing on the cable 5, the cable 5 can block the light path emitted by the light emitter 41, and the light receiver 4 controls the opening and closing of the motor 31 according to the received light intensity value.

[0026] When the cable 5 is being sprayed, the cable 5 is parallel to the photoelectric switch 36, and the cable 5 continues to pass through the space between the light receiver 4 and the light transmitter 41. The light receiver 4 cannot receive the light source emitted by the light transmitter 41, and the light intensity value is lower than the set value. At this time, the photoelectric switch 36 controls the motor 31 to turn off; when the cable 5 is sprayed, the cable 5 no longer blocks the light path, and the light intensity value received by the light receiver 4 is greater than the set value. The photoelectric switch 36 controls the motor 31 to start for 20S, so that the screw rotates and drives the slider 33 to move downward to the lower stop position; and then the nozzle 21 is driven to move downward to the lower stop position through the connecting rod 34, so that the nozzle 21 is close to the receiving hopper 13 to prevent the nozzle 21 from being too far away from the receiving hopper 13, causing ink to splash to the outside of the hopper 13 and pollute the ground and surrounding equipment. When the cable 5 needs to be sprayed again, the cable 5 continues to occupy the space between the light receiver 4 and the light transmitter 41, and the photoelectric switch 36 controls the motor 31 to start for 20S, so that the screw rod rotates and drives the slider 33 to move upward to the upper stop position; then the nozzle 21 is driven to move downward to the upper stop position through the connecting rod 34, so that the nozzle 21 maintains a suitable distance from the cable 5 to ensure the coding effect.
