Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire processing technology, and in particular to an automatic ink replenishment and homogenization device for printing mechanisms. Background Technology
[0002] In the wire manufacturing industry, in order to identify important information such as wire specifications, models, and production batches, it is usually necessary to print numbers on the surface of the wires. This is done using a wire marking machine, a specialized piece of equipment used in wire and cable production to print markings on the surface of the insulation layer. It can accurately mark wire specifications, models, trademarks, certification information, and other content, facilitating product identification and traceability.
[0003] However, the existing equipment has the following shortcomings: When using the existing equipment, the ink inside the material hopper needs to be manually added after it is used up. The manual addition is too cumbersome and causes low efficiency for users.
[0004] Therefore, we proposed an automatic ink replenishment and homogenization device for printing mechanisms to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies where equipment struggles to accurately add ink to the material hopper, and to propose an automatic ink replenishment and homogenization device for the printing mechanism.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: an automatic ink replenishment and homogenization device for a printing mechanism, comprising a mounting frame, a material hopper, a printing roller, a conveyor roller, a pressure roller, and a feeding device. The material hopper is fixedly connected to the upper end of the mounting frame. The conveyor roller is rotatably connected inside the material hopper. The printing roller is mounted above the conveyor roller and rotatably connected inside the material hopper. The pressure roller is slidably connected to the upper end of the material hopper. The feeding device is installed inside the material hopper and includes a mounting tube and a laser rangefinder. The mounting tube is fixedly connected to the material hopper. A laser rangefinder is fixedly connected inside the material hopper. The laser rangefinder is installed inside the mounting tube. A connecting plate is fixedly connected to the outer surface of the laser rangefinder. The connecting plate is fixedly connected to the inside of the mounting tube. A first wire is fixedly connected to the upper end of the laser rangefinder. A limiting plate is fixedly connected inside the material hopper. A feeding steel pipe is fixedly connected inside the limiting plate. A feed pipe is fixedly connected to the upper end of the feeding steel pipe. A pump is fixedly connected to the end of the feed pipe away from the feeding steel pipe. A mounting plate is fixedly connected to the surface of the pump. A material box is installed at the lower end of the mounting plate.
[0007] Furthermore, the pump is installed inside the material tank. By setting up the pump, the flow rate of the pump can be adjusted by the controller (5-20mL / min). With the real-time monitoring of the laser rangefinder, the fluctuation of the ink level in the material hopper is kept ≤5mm, reducing the risk of ink shortage in printing due to overflow from excessively high or low ink levels.
[0008] Furthermore, a second wire is fixedly connected to the upper end of the pump, and a controller is fixedly connected to the end of the second wire away from the pump. The second wire can transmit signals to the pump and provide power at the same time.
[0009] Furthermore, the controller is fixedly connected to the outer surface of the material box, and the end of the first wire away from the laser rangefinder is fixedly connected to the inside of the controller.
[0010] Furthermore, a stirring device is fixedly installed inside the mounting plate. The stirring device includes a servo motor and a mounting head. The mounting head is fixedly connected to the upper surface of the mounting plate, and the servo motor is fixedly connected to the upper surface of the mounting head. A stirring rod is rotatably connected to the lower end of the mounting head. By setting the mounting head, the servo motor can be limited, reducing the difficulty of limiting the servo motor during equipment use.
[0011] Furthermore, a stirring blade is fixedly connected to the end of the stirring rod away from the mounting plate.
[0012] Furthermore, a third wire is fixedly connected to the surface of the servo motor.
[0013] Furthermore, the end of the third wire furthest from the servo motor is fixedly connected to the surface of the controller.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] 1. In this utility model, by setting up a feeding device, the ink inside the material hopper is effectively added, which plays a role in automatic addition. This reduces the need for manual addition of ink inside the material hopper when the existing equipment is used up. Manual addition is too cumbersome and causes low addition efficiency for users. This feeding device realizes automatic feeding of the material hopper and improves the feeding efficiency of the equipment.
[0016] 2. In this utility model, by setting a stirring device with a spiral structure for the stirring blades, the precipitated ink at the bottom of the material box can be turned upwards, so that the pigment and solvent are fully mixed, reducing the uneven printing depth caused by uneven ink concentration in the material box. The controller can set the stirring frequency (e.g., stirring for 1 minute every 10 minutes), which ensures the homogenization effect and reduces energy consumption and ink foam generation.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0026] Please see Figures 1-6This utility model provides a technical solution: an automatic ink replenishment and homogenization device for a printing mechanism, including a mounting frame 1, a material hopper 2, a printing roller 3, a conveyor roller 4, a pressure roller 5, and a feeding device 6. The material hopper 2 is fixedly connected to the upper end of the mounting frame 1, the conveyor roller 4 is rotatably connected inside the material hopper 2, the printing roller 3 is installed above the conveyor roller 4 and is rotatably connected inside the material hopper 2, and the pressure roller 5 is slidably connected to the upper end of the material hopper 2.
[0027] Mounting bracket 1 is a metal frame structure, providing stable support and a solid mounting base for all components; material hopper 2 is a corrosion-resistant container used to store ink and ensure that the ink does not leak; the printing roller 3 has text and patterns engraved on its surface, which can pick up ink and print the patterns on the product surface; the feed roller 4 can transfer the ink in the material hopper 2 to the printing roller 3 to ensure uniform ink supply; the pressure roller 5 can press the product firmly onto the printing roller 3 to ensure clear printing.
[0028] The specific setup and function of the feeding device 6 and the mixing device 7 will be described in detail below.
[0029] In this implementation scheme: The feeding device 6 is installed inside the material hopper 2. The feeding device 6 includes an installation tube 61 and a laser rangefinder 62. The installation tube 61 is fixedly connected inside the material hopper 2. The laser rangefinder 62 is installed inside the installation tube 61. The installation tube 61 is a metal tube that fixes the laser rangefinder 62 to ensure accurate measurement. The laser rangefinder 62 is a high-precision detection component that can monitor the ink level in real time. A connecting plate 63 is fixedly connected to the outer surface of the laser rangefinder 62. The connecting plate 63 is fixedly connected to the inside of the installation tube 61. A first wire 610 is fixedly connected to the upper end of the laser rangefinder 62. A limit plate 64 is fixedly connected inside the material hopper 2. A feeding steel pipe 65 is fixedly connected inside the limit plate 64. A feed pipe 66 is fixedly connected to the upper end of the feeding steel pipe 65. A pump 68 is fixedly connected to the end of the feed pipe 66 away from the feeding steel pipe 65. An installation plate 69 is fixedly connected to the surface of the pump 68. A material box 67 is installed at the lower end of the installation plate 69.
[0030] Material box 67 is made of transparent material (5L capacity) to facilitate manual inspection of ink balance.
[0031] The SICK Laser Rangefinder 62 is a German-made laser rangefinder that is widely used in many fields such as industrial automation and machinery manufacturing due to its high precision and high reliability.
[0032] Specifically, pump 68 is installed inside material box 67.
[0033] Pump 68 is a miniature gear pump (flow rate adjustable from 5-20 mL / min, working pressure 0.1-0.3 MPa), which works in conjunction with feed pipe 66 to achieve pulse-free feeding and avoid ink splashing.
[0034] In this embodiment: by setting up pump 68, the flow rate of pump 68 can be adjusted by controller 611 from 5-20mL / min. With the real-time monitoring of laser rangefinder 62, the ink level fluctuation in material hopper 2 is kept ≤5mm, reducing ink shortage caused by overflow due to excessively high liquid level or insufficient liquid level.
[0035] Specifically, a second wire 612 is fixedly connected to the upper end of the pump 68, and a controller 611 is fixedly connected to the end of the second wire 612 away from the pump 68. The second wire 612 can transmit signals to the pump 68 and provide power at the same time.
[0036] The controller 611 is from the Siemens S7-1200 series: This series of controllers 611 has rich communication interfaces, which can be easily connected to the laser rangefinder 62, pump 68 and servo motor 71 to realize data transmission and control command issuance. It can quickly process the ink level data transmitted from the laser rangefinder 62. Through programming, the flow control logic of pump 68, as well as the speed and stirring frequency of servo motor 71 can be flexibly set. It has powerful logic control capabilities and can meet the complex control requirements of the device.
[0037] Specifically, the controller 611 is fixedly connected to the outer surface of the material box 67, and the end of the first wire 610 away from the laser rangefinder 62 is fixedly connected to the inside of the controller 611.
[0038] In this embodiment: A stirring device 7 is fixedly installed inside the mounting plate 69. The stirring device 7 includes a servo motor 71 and a mounting head 72. The mounting head 72 is fixedly connected to the upper surface of the mounting plate 69, the servo motor 71 is fixedly connected to the upper surface of the mounting head 72, and a stirring rod 73 is rotatably connected to the lower end of the mounting head 72.
[0039] In this embodiment, by setting the mounting head 72, the servo motor 71 can be limited, reducing the difficulty of limiting the servo motor 71 during use.
[0040] Specifically, a stirring blade 74 is fixedly connected to the end of the stirring rod 73 away from the mounting plate 69. The stirring blade 74 has a spiral structure and mixes evenly.
[0041] Specifically, a third wire 75 is fixedly connected to the surface of the servo motor 71.
[0042] Specifically, the end of the third wire 75 away from the servo motor 71 is fixedly connected to the surface of the controller 611.
[0043] Working principle: When the equipment is in use, ink and material are added to the inside of the material hopper 2 until it submerges half of the conveyor roller 4. The equipment is started, which drives the conveyor roller 4 to rotate. The conveyor roller 4 transfers the ink to the printing roller 3. The printing roller 3 and the pressure roller 5 work together to complete the printing on the surface of the wire. When the equipment needs to be refilled after long-term use, the laser rangefinder 62 is fixed in the mounting tube 61 through the connecting plate 63. The laser emitted by the rangefinder is perpendicular to the ink surface. The ink level is calculated by measuring the reflection distance. When the level is lower than the preset threshold, the laser rangefinder 62 transmits the signal to the controller 611 through the first wire 610. The controller 611 then contacts the controller through the second wire 612. Pump 68 operates, drawing ink from material tank 67 through feed pipe 66 and conveying it to material hopper 2 via feeding steel pipe 65. When the liquid level rises to the preset upper limit, laser rangefinder 62 sends a signal, and controller 611 shuts down pump 68, stopping replenishment and achieving fully automatic ink replenishment. By setting up feeding device 6, ink is effectively added to material hopper 2, achieving automatic replenishment. This reduces the need for manual replenishment of ink in material hopper 2 when it is used up, which is too cumbersome and results in low replenishment efficiency for users. This feeding device 6 realizes automatic feeding of material hopper 2, improving the feeding efficiency of the equipment.
[0044] Before the material is added to the material hopper 2, the controller 611 controls the speed of the servo motor 71 through the third wire 75. The servo motor 71 drives the stirring rod 73 and the stirring blade 74 at the lower end to rotate in the material box 67 at a speed of 50-200 rpm to continuously or intermittently stir the ink. By setting the stirring device 7, the stirring blade 74 adopts a spiral structure, which can turn the precipitated ink at the bottom of the material box 67 upward, so that the pigment and solvent are fully mixed, reducing the uneven printing depth caused by uneven ink concentration in the material box 67. The controller 611 can set the stirring frequency, such as stirring for 1 minute every 10 minutes, which ensures the homogenization effect and reduces energy consumption and ink foam generation.
[0045] When pump 68 starts to replenish the material, controller 611 simultaneously triggers the stirring device 7 to work, ensuring that the newly added ink mixes quickly with the original ink in material hopper 2, further improving the overall homogenization effect and avoiding local concentration differences from affecting the printing quality.
[0046] The above description discloses only one or more preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of the present utility model still fall within the scope of the present utility model.
