Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a device for mixing and preparing printing ink. Background Art

[0002] The statements herein only provide background art related to the utility model and do not necessarily constitute prior art.

[0003] In the wire and cable production industry, when producing small-sized cables, a printing machine wheel is required to print characters on the cable surface. The cable passes through a pressure wheel and a printing wheel under traction, and the grooves on the concave printing wheel transfer the stored ink to the cable surface.

[0004] In the actual production process, due to the high viscosity of the ink, production personnel need to add diluent to the ink regularly. Such an operation method may cause problems such as excessive addition of diluent, insufficient addition of diluent, and uneven stirring, resulting in phenomena such as oil lines, water marks, blurring, and inconsistent printing colors on the cable. Moreover, since the production speed of such cables is in a high-speed operation process, the printing situation cannot be verified at high speed, and accurate inspection can only be carried out at the end of a round of production. At this time, if the printing appears as described above, it needs to be wiped and printed again, increasing the labor intensity, production cost, and time cost of production personnel and affecting the delivery date.

[0005] In the Chinese patent with the authorization announcement number CN202098102U, a device for controlling the concentration of wire printing ink is disclosed, which uniformly adds diluent to the ink at a constant speed by using a total flow control valve and a flow rate control valve to uniformly dilute the ink and control the concentration of the ink. However, it only focuses on the addition control of the diluent and lacks the monitoring of the real-time viscosity of the ink, and there is still a risk of excessive dilution or insufficient dilution, affecting subsequent production.

[0006] In addition, during the production process, there is likely to be excess ink on the printing wheel, resulting in scratching of the characters printed on the cable. Summary of the Utility Model

[0007] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a device for mixing and preparing printing ink, which uses a viscosity detector to monitor the viscosity of the ink in the mixed ink box in real time, ensuring that the viscosity of the ink in the mixed ink box is uniform and meets the requirements.

[0041] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present utility model. Unless otherwise specified, all technical and scientific terms used in the present utility model have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs.

[0042] As introduced in the background art, during the printing process of the existing cable 13, the viscosity of the ink is difficult to meet the actual production requirements and the viscosity is not uniform, resulting in poor printing effects on the cable 13. To solve the above technical problems, the present utility model proposes a printing ink dispensing device.

[0043] Combined with Figure 1 , the printing ink dispensing device includes a base 12, a viscosity detector 9 and a controller 1.

[0044] A mounting plate connected to the inner wall of the receiving groove is fixed in the receiving groove, an ink nozzle 6 is mounted on one end of the mounting plate, an ink scraper 7 is mounted on the other end of the mounting plate, and a rotating shaft is mounted in the middle of the mounting plate, which passes through the printing wheel 4 and is rotatably connected to the printing wheel 4, so that the printing wheel 4 rotates along the rotating shaft. The middle and lower part of the printing wheel 4 is located in the receiving groove, and the highest point of the printing wheel 4 is greater than the highest point of the receiving groove, so that the printing wheel 4 can contact the cable 13. The ink scraper 7 abuts against the outer surface of the printing wheel 4.

[0045] The pressing wheel 3 and the printing wheel 4 are arranged opposite to each other, and there is a gap between the pressing wheel 3 and the printing wheel 4. The radius of the pressing wheel 3 matches the diameter of the cable 13, so that the gap between the pressing wheel 3 and the printing wheel 4 matches the diameter of the cable 13, so that the cable 13 can pass between the pressing wheel 3 and the printing wheel 4, and the cable 13 can be pressed against the printing wheel 4. Along the moving direction of the cable 13, a group of guide wheels 5 arranged opposite to each other are installed on one side of the pressing wheel 3. The guide wheels 5 are located at the outlet of the previous process and are used to pull the cable 13 produced in the previous process to move between the pressing wheel 3 and the printing wheel 4. The movement of the cable 13 drives the rotation of the pressing wheel 3 and the printing wheel 4.

[0046] The solvent box 2 is connected to the mixing ink box 11 through a hose, and a valve for controlling the circulation of the diluent is installed on the hose. An ink pump is installed in the mixing ink box 11, and the ink pump is connected to the ink nozzle 6 through the hose, so that the ink mixed evenly in the mixing ink box 11 is transported to the ink nozzle 6 and sprayed to the printing wheel 4 through the ink nozzle 6; the viscosity detector 9 is installed in the mixing ink box 11, and the viscosity detector 9 is electrically connected to the controller 1, and the controller 1 is electrically connected to the valve; the viscosity detector 9 is used to collect the ink viscosity information in the mixing ink box 11 in real time and transmit it to the controller 1; the controller 1 sends an electrical signal to control the opening and closing of the valve based on the comparison between the ink viscosity information and the preset target viscosity value, so that the addition of the diluent meets the ink viscosity requirements during production.

[0048] In order to ensure uniform mixing of ink and diluent during the injection process of the diluent, as an embodiment, a stirring paddle 10 is installed in the mixing ink box 11. The stirring paddle 10 includes a paddle and a rotating motor. The rotating motor is fixed to the inner wall of the mixing ink box 11. The output end of the rotating motor is coaxially connected to the paddle.

[0050] In this embodiment, the controller 1 is a controller 1 configured in a viscosity controller of model Fasnacht-S6-VR, and the viscosity detector 9 is a viscosity detection probe configured in a viscosity controller of model Fasnacht-S6-VR.

[0051] The working method of this embodiment is as follows:

[0052] The viscosity detector 9 collects the ink viscosity information in the mixed ink box 11 in real time and transmits it to the controller 1. The controller 1 receives the ink viscosity information and compares it with the preset target viscosity value. If it is greater than the preset target viscosity value, an electrical signal is sent to start the valve, and the diluent in the solvent box 2 drips into the mixed ink box 11; until the ink viscosity information in the mixed ink box 11 is equal to the preset target viscosity value, an electrical signal is sent to control the valve to close. The ink nozzle 6 sprays the mixed ink evenly on the surface of the printing wheel 4. During the rotation of the printing wheel 4, the ink scraper scrapes off the excess ink, and the excess ink flows back to the mixed ink box 11 along the ink return pipe 8; the cable 13 is pulled through the pressure wheel 3 and the printing wheel 4 by the guide wheel 5, driving the printing wheel 4 to rotate, and the groove on the printing wheel 4 contacts the surface of the cable 13, transferring the ink to the surface of the cable 13.
