Description

Technical Field

[0001] The present invention relates to a cable ink spraying device for producing spiral inter-color cables. Background Art

[0002] With the development of the cable industry, various cables are increasingly widely used. In order to distinguish their uses, the outer surfaces of cables are made into various colors, including inter-colors. At present, the inter-color cables produced in the cable industry mainly include single inter-colors, with the main color accounting for about 70% and the secondary color accounting for about 30%. Single inter-colors have gradually developed into double inter-colors, and even more, into triple inter-colors, etc. The main purpose is to enable the cable to be distinguished by its color when observed from different angles. However, whether it is a single inter-color or a double inter-color, during the installation and laying process, there is still a situation where the inter-color strips are blocked, and it is impossible to achieve 360° full-angle identification of the cable's appearance color. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a cable ink spraying device to realize the production of spiral inter-color cables and achieve no dead angle in the identification of cable colors (inter-colors).

[0004] To solve the above technical problem, the cable ink spraying device of the present invention includes an outer ring body and a rotating inner ring body, and the rotating inner ring body rotates within the outer ring body; the surface of the rotating inner ring body has an annular ink storage tank, the ink storage tank has nozzle mounting holes, nozzles are installed in the nozzle mounting holes, and the nozzles can be replaced according to the size requirements of the cable. The ink in the ink storage tank is sprayed towards the inside of the rotating inner ring body through the nozzles; the outer ring body has an ink inlet, the position of the ink inlet corresponds to the ink storage tank, and the ink introduced through the ink inlet enters the ink storage tank; on at least one side of the ink storage tank, the inner wall of the rotating inner ring body has an annular ink collecting tank, and the annular ink collecting tank has ink leakage holes; on the inner side of the rotating inner ring body, the inner surface between the ink storage tank and the ink collecting tank is conical; the inner surface of the outer ring body has a collecting tank, the position of the collecting tank corresponds to the ink collecting tank, and the ink in the ink collecting tank enters the collecting tank through the ink leakage holes.

[0005] The ink supply device (which can refer to the existing inkjet printer) is connected to the ink inlet to achieve continuous ink supply. The ink enters the ink storage tank, and a nozzle (which can refer to the nozzle of the existing inkjet printer) is installed in the ink storage tank. Under a certain pressure (ink supply pressure), the ink is ejected from the nozzle in a specified amount. The cable passes through the rotating inner ring body and travels inside the rotating inner ring body, that is, the cable has a linear velocity of horizontal advancement. At this time, the rotating inner ring body rotates, driving the nozzle to rotate for inkjet movement, so as to achieve a spiral spraying effect on the cable. The ink dries on the surface of the cable. For example, the cable can rely on its own high temperature (generated during production) to facilitate the drying and rubbing resistance of the ink. For the ink ejected from the nozzle, some of the ink may not be aligned with the cable or leak. Through the slope structure on the inner side of the rotating inner ring body (that is, the inner side is conical), the ink enters the ink collection tank on the inner side of the outer ring body through the ink leakage hole. Under the action of centrifugal force, the remaining ink is recycled. Specifically, the collection tank is connected with a recovery pipe, and the recovery pipe discharges the ink in the collection tank for reuse.

[0006] Because the spraying of the ink requires a certain pressure, or rather, the ink supply device can provide ink with a certain pressure. To prevent the ink from leaking between the outer ring body and the rotating inner ring body, on both sides of the ink storage tank, a circular first sealing ring installation groove is provided on the surface of the rotating inner ring body, and a first O-ring is installed in the first sealing ring installation groove. At least one first sealing ring installation groove (installed with a first O-ring) is provided on either side of the ink storage tank. For example, two first sealing ring installation grooves (installed with first O-rings) are provided on each side of the common ink storage tank.

[0007] Similarly, on both sides of the collection tank, a circular second sealing ring installation groove is provided on the inner side of the outer ring body, and a second O-ring is installed in the second sealing ring installation groove. At least one second sealing ring installation groove (installed with a second O-ring) is provided on either side of the collection tank. For example, two second sealing ring installation grooves (installed with second O-rings) are provided on each side of the common ink storage tank.

[0008] After the ink enters from the ink inlet, although there is pressure, the inner wall is constantly rotating and pressure is released at the nozzle, so the pressure acting on the gap between the inner cavity and the outer ring is relatively small and it is not easy for the ink to leak.

[0009] Specifically, as a preference, the cross-section of the ink storage tank is trapezoidal.

[0010] As a driving structure of the rotating inner ring body, one end of the rotating inner ring body extends out of the outer ring body. A synchronous belt groove is provided on the extended part of the rotating inner ring body, and a belt is installed in the synchronous belt groove. The belt is connected to the motor, and the motor drives the rotating inner ring body to rotate through the belt.

[0011] The size of the ink inlet is larger than that of the nozzle, and the nozzle can be replaced from the outside of the outer ring body, which is convenient and efficient.

[0012] The cable ink spraying device of the present invention has a simple structure and realizes the spraying production of spiral inter-color cables. After the cable material is extruded and formed in a high-temperature molten state, its surface still has a relatively high temperature. Utilizing its own temperature, ink is sprayed on it, which can achieve rapid drying and high production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0017] As Figures 1-3 shown, the cable ink spraying device includes an outer ring body 1 and a rotating inner ring body 2, and the rotating inner ring body 2 rotates inside the outer ring body 1. Specifically, one end of the rotating inner ring body 2 extends out of the outer ring body 1, and a synchronous belt groove 15 is provided on the extended part of the rotating inner ring body 2. A belt 16 is installed in the synchronous belt groove 15, and the belt 16 is connected to a motor 17. The motor 17 drives the rotating inner ring body 2 to rotate through the belt 16.

[0018] The surface of the rotating inner ring body 2 is provided with an annular ink storage groove 3. The cross-section of the ink storage groove 3 is trapezoidal. A nozzle mounting hole 5 is provided in the ink storage groove 3, and a nozzle 20 is installed in the nozzle mounting hole 5. The nozzle 20 can be replaced according to the size requirements of the cable 21 (that is, a suitable ink nozzle 20 is selected according to the diameter of the cable 21 and the width of the spiral inter-color stripe). The ink in the ink storage groove 3 is sprayed onto the inside of the rotating inner ring body 2 through the nozzle 20. An ink inlet 4 is provided on the outer ring body 1, and the position of the ink inlet 4 corresponds to the ink storage groove 3. The ink introduced through the ink inlet 4 enters the ink storage groove 3.

[0019] On at least one side of the ink storage tank 3 (such as on both sides of the ink storage tank 3), there is an annular ink collection tank 7 on the inner wall of the rotating inner ring body 2, and there are ink leakage holes 8 on the annular ink collection tank 7 (such as 4 evenly distributed ink leakage holes); inside the rotating inner ring body 2, the inner side surface 6 (inner wall) between the ink storage tank 3 and the ink collection tank 7 is conical; the inner side surface of the outer ring body 1 has a collection tank 10, and the position of the collection tank 10 corresponds to that of the ink collection tank 7. The ink in the ink collection tank 7 enters the collection tank 10 through the ink leakage holes 8. The inner side surface of the rotating inner ring body 2 has a certain slope (i.e., conical), and during the rotation of the rotating inner ring body 2, the remaining ink will continuously be thrown onto the inner wall of the rotating inner ring body 2 due to the action of centrifugal force; under the action of the slope, the remaining ink flows along the inner wall to both sides. After the ink accumulates in the ink collection tank 7, it is ejected from the rotating inner ring body 2 through the ink leakage holes 8 and enters the ink collection tank 10 of the outer ring body 1. The collection tank 10 is connected to an ink recovery pipe 18, and the recovery pipe 18 stores the remaining ink in the liquid storage tank 19.

[0020] The size of the ink inlet 4 (which can be a threaded hole connected to the ink supply device) is larger than the size of the nozzle 20, and the nozzle 20 can be replaced from the outside of the outer ring body 1, which is convenient and efficient.

[0021] The ink supply device (which can refer to the existing inkjet printer) is connected to the ink inlet 4 to achieve continuous ink supply. The ink enters the ink storage tank 3, and a nozzle 20 (which can refer to the nozzle of the existing inkjet printer) is installed in the ink storage tank 3. Under the action of a certain pressure (ink supply pressure), the ink is ejected from the nozzle 20 to form a specified amount of ink. The cable 21 passes through the rotating inner ring body 2 and travels inside the rotating inner ring body 2, that is, the cable 21 has a linear velocity of horizontal advancement. At this time, the rotating inner ring body 2 rotates, driving the nozzle 20 to rotate for inkjet movement, so as to achieve a spiral spraying effect on the cable 21. The ink dries on the surface of the cable 21. For example, the cable 21 can rely on its own high temperature (generated during production) to be conducive to the drying and rubbing resistance of the ink. Some of the ink ejected from the nozzle 20 may not be aligned with the cable or leak. Through the slope structure of the inner side surface of the rotating inner ring body 2 (i.e., the inner side surface is conical), it enters the ink collection tank 10 on the inner side surface of the outer ring body 1 through the ink leakage holes 8. Under the action of centrifugal force, the remaining ink is recycled and reused. Specifically, the collection tank 10 is connected to a recovery pipe 18, and the recovery pipe 18 discharges the ink in the collection tank 10 for reuse.

[0022] After the ink enters from the ink inlet, although there is pressure, the inner wall is rotating continuously, and pressure is relieved at the nozzle 20. Therefore, the pressure acting on the gap between the rotating inner ring 2 and the outer ring 1 is relatively small, and it is not easy for the ink to leak. Since the spraying of the ink requires a certain pressure, or in other words, the ink supply device can provide ink with a certain pressure, in order to prevent the ink from leaking between the outer ring 1 and the rotating inner ring 2, on each side of the ink storage tank 3, two annular first sealing ring installation grooves 11 are provided on the surface of the rotating inner ring 2, and a first O-ring 12 is installed in the first sealing ring installation groove 11. Similarly, on each side of the collection tank 10, two annular second sealing ring installation grooves 13 are provided on the inner side surface of the outer ring 1, and a second O-ring 14 is installed in the second sealing ring installation groove 13.

[0023] The motor and the liquid storage tank are placed on the base, and the device of the present invention is installed on the base through the support rod. During the extrusion process of the cable, the ink is sprayed in a circular rotation, and as the cable is extruded in a linear motion, the two cooperate to form a spiral inter-color.

[0024] The present invention can be installed between the head of the extruder and the first cooling water tank. After the cable material is extruded and formed in a high-temperature molten state, its surface still has a relatively high temperature. By using its own temperature, the ink is sprayed on it, and rapid drying can be achieved.

[0025] The above embodiments do not limit the present invention in any way. Any technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
