Description

Technical Field

[0001] The present application relates to the technical field of cable printing equipment, and in particular to a cable fluorescent marking printing process and device. Background Art

[0002] Since the cable is directly covered with an outer sheath, the specific model of the cable cannot be directly understood through the external structure. Therefore, the specific model of the cable is usually printed on the outer sheath of the cable so that the cable model can be intuitively understood.

[0003] Currently, during the printing process, ink is usually printed directly onto the cable using a printing wheel. A certain amount of diluent is usually added to the ink when it is used to prevent the ink from being too viscous. However, since the diluent is relatively volatile, the diluent in the ink will continue to decrease during the printing process, causing the ink to become viscous, affecting the normal printing of the ink.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Summary of the Invention

[0005] In order to reduce the volatilization of the diluent in the ink during the printing process, the present application provides a cable fluorescent marking printing process and device.

[0010] By adopting the above technical solution, the feed port and the discharge port are closed during the cable printing process, thereby reducing the area of ​​air that can circulate inside and outside the box, making it difficult for the volatilized diluent in the box to leak to the outside, and also making it difficult for the sealing leaf and the cable to move relative to each other, so that the pattern printed on the cable is not easily erased.

[0014] By adopting the above technical solution, when the sealing leaves move with the cable and drive the air between adjacent sealing leaves to move out of the box, the air containing the diluent is drawn back into the box by the air return mechanism, thereby further reducing the leakage of the diluent.

[0016] By adopting the above technical solution, when the air outside the box is transported into the box through the space between the sealing leaves, the air outside the box located between adjacent sealing leaves is again drawn out into the box by the exhaust mechanism, thereby not causing the air pressure inside the box to increase and reducing the leakage of diluent caused by pressure imbalance.

[0017] Optionally: a sealing strip is provided on the end surface of the sealing leaf away from the closure member, the area of ​​the sealing strip away from the sealing leaf is smaller than the area of ​​the sealing strip close to the sealing leaf, and the sealing strip can abut against the cable.

[0037] The present application is further described in detail below with reference to the accompanying drawings.

[0038] The present application discloses a cable fluorescent marking printing device, such as Figure 1 and Figure 2As shown, it includes a box body 1 with an upper opening and a printing mechanism 2 arranged inside the box body 1. The upper end of the box body 1 is detachably connected to a cover plate 11 that can open and close its opening. The cover plate 11 is fixed to the upper end surface of the box body 1 by butterfly bolts, and a transparent observation window 12 is provided on the cover plate 11. The amount of ink inside the box body 1 can be observed through the observation window 12. A feed port 13 is provided on a vertical side wall on one side of the box body 1, which is connected to its inner cavity. A discharge port 14 is provided on the other side wall of the box body 1, which is connected to its inner cavity. The axes of the feed port 13 and the discharge port 14 coincide with each other, and cables are passed through the feed port 13 and the discharge port 14. The printing mechanism 2 includes a printing wheel 21 that is rotatably connected to the box body 1, a wire pressing wheel 22 that determines the position of the cable, and a printing drive 23 that drives the printing wheel 21 to rotate. The printing drive 23 is a motor in this embodiment. The printing wheel 21 is positioned below the crimping wheel 22, with the lower end of the printing wheel 21 able to contact the ink within the housing 1. A cable is positioned between the printing wheel 21 and the crimping wheel 22. The crimping wheel 22 is used to push the cable against the printing wheel 21, thereby allowing the printing wheel 21 to print the ink onto the cable surface. A reducer is mounted on the outer wall of the housing 1 to secure the motor. The reducer's input shaft is coaxially fixed to the motor's output shaft, and the reducer's output shaft is coaxially fixed to the printing wheel 21, thereby driving the printing wheel 21 to rotate. A scraper 24 is also secured within the housing 1 to remove excess ink from the printing wheel 21. The scraper 24 contacts the outer wall of the printing wheel 21 to scrape away excess ink adhering to the printing wheel 21.

[0039] like Figure 3 As shown, a sealing mechanism 3 is installed within the discharge port 14 to reduce leakage of volatile diluent from the discharge port 14. The sealing mechanism 3 comprises a closure member 31 rotatably connected to the discharge port 14 and a plurality of sealing leaves 32 disposed on the outer wall of the closure member 31. The closure member 31 is arranged in a rotating manner, and the movement direction of the upper end of the closure member 31 is the same as the conveying direction of the cable. There is a gap between adjacent sealing leaves 32, and the end of the sealing leaf 32 away from the closure member 31 can abut and seal the lower end of the cable. The sidewalls of the sealing leaves 32 can contact and seal the vertical inner wall of the discharge port 14. The lower end of the sealing leaf 32 located below the closure 31 can abut against and seal the inner wall of the lower end of the discharge port 14, so that in the process of transporting the cable toward the outside of the box 1, the sealing leaf 32 abuts against the cable and moves synchronously with the cable. There is no relative movement between the sealing leaf 32 and the cable, making it difficult for the sealing leaf 32 to scratch the printing on the surface of the cable. At the same time, the sealing leaf 32 can also prevent the discharge port 14 from being directly connected to the outside world, thereby reducing the amount of volatilized diluent moving to the outside world through the discharge port 14.

[0040] like Figure 1 and Figure 3As shown, in order to further enhance the sealing effect of the housing 1 and reduce the amount of diluent that enters the outside of the housing 1, a feed seal ring 15 is provided at the feed port 13. The feed seal ring 15 is made of engineering plastic, and the cable is passed through the feed seal ring 15, and the outer wall of the cable is in contact with the feed seal ring 15. A discharge seal ring 16 made of engineering plastic is also provided in the discharge port 14. The discharge seal ring 16 can abut and seal with the upper end of the cable, and the upper end of the sealing leaf 32 can abut and seal with the lower end surface of the discharge seal ring 16, thereby further reducing the gap through which air can pass between the discharge port 14 and the feed port 13, thereby reducing the leakage of diluent.

[0041] like Figure 2 and Figure 3 As shown, during cable transport, the air between adjacent sealing leaves 32 also contains diluent. As the sealing leaves 32 move, the diluent trapped therein also moves outside the housing 1, causing the diluent to evaporate. Therefore, the housing 1 is also equipped with an air return mechanism 4 that draws air from adjacent sealing leaves 32 above the sealing member 31 back into the housing 1. This mechanism 4 includes an air return port 41 within the discharge port 14 and an air return drive 42 for driving air into the housing 1. In this embodiment, the air return drive 42 is an air pump. The air return port 41 is positioned above the sealing member 31 and below the cable arrangement. It communicates with the space between adjacent sealing leaves 32. The air return drive 42 is bolted to the exterior of the housing 1. The air inlet of the air return drive 42 communicates with the air return port 41, while the air outlet of the air return drive 42 communicates with the interior of the housing 1 and is above the upper surface of the ink within the housing 1. When the sealing leaf transports the air containing the diluent in the box body 1 toward the outside, the air return mechanism 4 can be used to suck the air containing the diluent back into the box body 1, thereby reducing the leakage of the diluent.

[0042] When the sealing leaves 32 move toward the interior of the housing 1, they also drive air from outside the housing 1 into the housing 1, thereby increasing the air pressure inside the housing 1. This increased air pressure accelerates the flow of air from the housing 1 into the outside world through the gaps between the various mechanisms, further accelerating the leakage of the diluent. Therefore, the housing 1 is also provided with an exhaust mechanism 5 for conveying air outward between adjacent sealing leaves 32 located below the closure member 31. The exhaust mechanism 5 includes an exhaust port 51 disposed within the discharge port 14 and an exhaust drive 52 for driving the air flow. In this embodiment, the exhaust drive 52 is an air pump. The exhaust port 51 is disposed below the closure member 31 and is capable of communicating with the space formed by the adjacent sealing leaves 32. The air inlet of the exhaust drive 52 is connected to the exhaust port 51, and the air outlet of the exhaust drive 52 is in communication with the outside of the housing 1. Therefore, when the sealing leaves 32 drive the outside air to move into the box body 1, the exhaust drive member 52 is used to discharge the air between adjacent sealing leaves 32 to the outside of the box body 1, making it difficult for the outside air to enter the box body 1 and increase the air pressure inside the box body 1.

[0043] like Figure 3 As shown, to enhance the sealing effect between the sealing leaf 32 and the cable, a sealing strip 33 is provided on the end surface of the sealing leaf 32 away from the closure member 31. The sealing strip 33 is made of rubber, and the end of the sealing strip 33 away from the sealing leaf 32 can abut against the cable or the inner wall of the discharge port 14. The area of ​​the end of the sealing strip 33 away from the sealing leaf 32 is smaller than the area of ​​the end closer to the sealing leaf 32, thereby reducing the contact area between the sealing strip 33 and the cable and reducing the possibility of the printed pattern on the cable being erased.

[0044] like Figure 2 As shown, after long-term use, a certain separation will occur between the ink and the diluent, resulting in uneven distribution of the ink inside the box 1, thereby affecting the printing effect of the printing wheel 21. Therefore, a stirring mechanism 6 for stirring the ink is also provided in the box 1. The stirring mechanism 6 includes a stirring paddle 61 rotatably connected to the box 1 and a stirring drive 62 for driving the stirring paddle 61 to rotate. In this embodiment, the stirring drive 62 is a motor. The stirring paddle 61 is arranged horizontally and immersed in the ink in the box 1. The stirring paddle 61 is arranged parallel to the conveying direction of the cable. The stirring drive 62 is fixed to the side wall of the box 1 with a feed port 13 using bolts. The output shaft of the stirring drive 62 is connected to a reducer, and the output shaft of the reducer is connected to the stirring paddle 61.

[0045] like Figure 1 and Figure 2As shown, the housing 1 is also provided with an injection mechanism 7 for automatically injecting diluent into the housing 1. The injection mechanism 7 includes a water tank 71 for storing the diluent, an injection drive 72 for driving the diluent into the housing 1, a detection member 73 for detecting the viscosity of the ink, and a control unit for controlling the operation of the injection drive 72. In this embodiment, the detection member 73 is a liquid concentration sensor. The detection member 73 and the injection drive 72 are both electrically connected to the control unit. The detection end of the detection member 73 passes through the housing 1 and is placed in the ink in the housing 1. In this embodiment, the injection drive 72 is a water pump. The water inlet end of the injection drive 72 is connected to the water tank 71, and the water outlet end of the injection drive 72 is connected to the inner wall of the housing 1. When the detection member 73 detects that the concentration of the ink exceeds its preset concentration, a feedback signal is sent to the control unit, which controls the injection drive 72 to inject a rated amount of diluent into the housing 1, thereby achieving the function of automatically adding diluent.

[0046] The working principle of this embodiment is as follows: the cable enters the housing 1 through the feed port 13 and passes between the crimping wheel 22 and the printing wheel 21. The printing wheel 21 rotates synchronously with the cable, printing ink on the cable surface. The cable then moves to the discharge port 14, where the sealing leaf 32 abuts the cable surface, causing the sealing leaf 32 to move synchronously with the cable. As the sealing leaf 32 passes through the opening of the air return port 41, the air return port 41 draws air back into the housing 1. During the operation of the air return port 41, the exhaust port 51 also discharges the air between the sealing leaves 32 below to the outside.

[0047] A cable fluorescent marking printing process includes the following steps:

[0048] S1. Rinse, wipe and dry the cable surface;

[0049] S2. Adhere the ink injected with diluent to the printing wheel 21 and scrape off excess ink on the printing wheel 21. Place the cable against the printing wheel 21 and rotate the printing wheel 21 as the cable moves, so that the ink adhered to the printing wheel 21 is transferred to the cable. During the movement of the cable, the space where the ink contacts the outside is sealed.

[0050] S3. Send hot air toward the cable printing position to dry the ink.

[0051] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
