Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating device technology, and in particular to a coating device for wires. Background Technology
[0002] HDMI cables contain multiple sets of core wires and are covered with aluminum foil. The main function of the aluminum foil is to shield high-frequency electromagnetic waves, preventing them from contacting the cable conductors and generating induced current, thus increasing crosstalk. The aluminum foil is wrapped around the cable by pulling the cable upwards from one end while the aluminum foil is rotated around the cable on one side to achieve the effect of wrapping the cable. When the cable is pulled up and wrapped, it will bend due to the tension generated during the wrapping process. The bending is more severe for thinner cables. This bending can lead to localized stress concentration in the cable. Excessive bending can damage the core wires and affect the wrapping effect, thus affecting the shielding effect of the aluminum foil. Utility Model Content

[0021] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.
[0022] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0023] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.
[0024] In existing technology, the outer layer of the wire 6 is covered with aluminum foil by pulling the wire 6 from one end to the other, and the aluminum foil covering 7 rotates around the wire 6 to cover it. The wire 6 will bend due to the tension generated during the wrapping process, thus achieving a shielding effect. This invention provides a wrapping device for the wire, based on the principle of pulling the wire 6 upwards. This device's wrapping method prevents the wire 6 from bending, thus protecting the wire 6. Figure 1-4 As shown, it includes a fixed base 1, a feeding structure 2 disposed at the lower part of the fixed base 1, a discharging structure 3 disposed at the upper part of the fixed base 1, and a covering structure 4 disposed between the feeding structure 2 and the discharging structure 3. The side of the covering structure 4 closest to the feeding structure 2 is the input end 401, and the other end is the output end 402. The feeding structure 2 is used to guide the wire 6 and the covering material 7 to move to the covering structure 4. The covering structure 4 is used to guide the winding of the covering material 7 to cover the wire 6. The discharging structure 3 is used to output the wire 6 that has been covered by the covering material 7.
[0025] The feeding structure 2 is responsible for introducing the wire 6 and the covering material 7, such as aluminum foil, into the device, improving the stability and accuracy of both during feeding. The discharging structure 3 makes the covering material 7 fit the wire 6 better. The wire 6 and the covering material 7 pass through the feeding structure 2 and enter the wrapping structure. The wire 6 is placed on the wrapping structure 4. The covering material 7 is rolled up by the wrapping structure 4 to wrap the wire 6 on the wrapping structure 4, forming a wrapping layer around the wire 6. After wrapping, the combination of the wire 6 and aluminum foil leaves the wrapping device through the discharging structure 3, which can realize continuous wrapping. The covering material 7 is guided by the wrapping structure 4, and the wrapping process does not generate bending force on the wire 6. The wrapping effect is good, the guided wrapping speed is fast, and the production efficiency is high.
[0026] In some embodiments, as Figure 1-3 As shown, the covering structure 4 includes a bending guide plate 410 for rolling up the covering 7. The bending guide plate 410 includes a first guide plate 411 located on one side of the bending guide plate 410. In the direction from the input end 401 to the output end 402, the curvature of the first guide plate 411 bending inward gradually increases.
[0027] The gradually increasing curvature of the first guide plate 411 bending inward helps to guide the covering material 7 to adhere to the wire 6 and complete the wrapping without causing excessive stretching or tearing of the material. The first guide plate 411 can be a double-sided wrapping or a single-sided spiral wrapping. The double-sided wrapping structure allows the covering material 7 to be rolled up symmetrically or offset from both sides to wrap the wire 6. The single-sided spiral wrapping structure gradually increases the curvature of the first guide plate 411 to form a spiral shape. The aluminum foil is rolled up along the spiral of the first guide plate 411 and wrapped around the wire 6 passing through the first guide plate 411, thus achieving single-sided wrapping of the wire 6.
[0028] Furthermore, the bending guide plate 410 also includes a second guide plate 412 located on the other side of the first guide plate 411, and the curvature of the second guide plate 412 bending inward gradually increases in the direction from the input end 401 to the output end 402.
[0029] The cooperation between the second guide plate 412 and the first guide plate 411 facilitates the wrapping material 7 to be rolled up along the second guide plate 412 and the first guide plate 411 to wrap the wire 6, thus achieving double-sided wrapping. The double-sided guide structure makes the wrapping speed faster and improves production efficiency.
[0030] Furthermore, the covering structure 4 also includes a shaping ring 413 located at its output end 402, the shaping ring 413 being connected to the bending guide plate 410 for the rolled-up covering 7 and wire 6 to pass through the shaping ring 413.
[0031] In practice, the first guide plate 411 and the second guide plate 412 are intersected at the end, which makes the coverage better and facilitates the guidance of the covering material 7 to further fit the wire 6, thereby improving the coverage. The shaping ring 413 set at the output end 402 of the covering structure plays a role in limiting and shaping the first guide plate 411 and the second guide plate 412, improving the firmness and enhancing the stability of the covering effect.
[0032] In some embodiments, as Figure 1-3 As shown, the bending guide plate 410 has two limiting plates 420 on its lower sides, and the covering 7 passes between the bending guide plate 410 and the limiting plates 420.
[0033] When the covering material 7 passes through the covering structure 4, it will first be guided into the space between the limiting plate 420 and the bending guide plate 410, thereby limiting and guiding the edge of the covering material 7, reducing the premature bending of the covering material 7, which would affect subsequent feeding, and making the covering material 7 fit the bending guide plate 410 better, so that the covering material 7 can be better wrapped along the predetermined path on the bending guide plate 410.
[0034] In some embodiments, as Figure 1-3 As shown, the bending guide plate 410 also includes a third guide plate 430 connected to the input end of the bending guide plate 410 and bent toward the fixed base 1.
[0035] Specifically, there is a certain height difference between the feeding structure 2 and the covering structure 4. The covering material 7 may be deviated during the feeding process. The third guide plate 430 facilitates the guidance of the covering material 7 from the feeding structure 2 to the bending guide plate 410.
[0036] In some embodiments, as Figure 1-4 As shown, a coating device for wires further includes an adjustment structure 5 for adjusting the coating structure 4. The adjustment structure 5 includes a first adjustment structure 510 connected to one side of the output end 402 of the coating structure 4. The first adjustment structure 510 is used to adjust the concentricity between one side of the output end 402 of the coating structure 4 and the feeding structure 2 and the discharging structure 3.
[0037] To reduce the offset and bending of the wire 6 during the wrapping process, the centers of the wire 6 should be on the same straight line when passing through the feeding structure 2, the output end 402 of the wrapping structure 4, and the discharge structure 3. In fact, the wrapping structure 4 can be disassembled, replaced, or moved. To adjust the concentricity, the first adjustment structure 510 can be provided with a threaded hole on the fixed seat 1. A screw that matches the threaded hole is used. The front end of the screw abuts against the back side of the output end 402 of the wrapping structure 4. The wrapping structure 4 has a certain elastic deformation characteristic and will deform slightly when it abuts. By rotating the screw, the screw can be extended forward or extended backward, thereby adjusting the concentricity. This makes it convenient to readjust the concentricity between the output end 402 of the wrapping structure 4 and the feeding structure 2 and the discharge structure 3 after each position change.
[0038] In some embodiments, as Figure 1-4 As shown, a coating device for wires further includes an adjustment structure 5 for adjusting the coating structure 4. The adjustment structure 5 includes a second adjustment structure 520 connected to the coating structure 4. The second adjustment structure 520 is used to adjust the position of the coating structure 4 on the fixed base 1.
[0039] The second adjustment structure 520 can specifically be an adjustment seat provided after the covering structure 4. The covering structure 4 is fixed on the adjustment seat. The position of the covering structure 4 on the fixed seat 1 can be adjusted by adjusting the adjustment seat, reducing the influence on the shape of the bending guide plate 410 of the covering structure 4. The specific adjustment method can be that the fixed seat is provided with a sliding groove, multiple through holes, etc. The adjustment seat of the covering structure 4 and the fixed seat 1 are fastened by bolts or other fastening structures passing through the groove or holes for adjustment and fastening. The position of the covering structure 4 on the fixed seat 1 can be adjusted by adjusting the position of the bolts or other structures on the sliding groove or through holes, so as to adapt to more wires 6 and coverings 7 structures.
[0040] In some embodiments, as Figure 1 As shown, the feeding structure 2 includes a feeding hole 210 that matches the wire 6 and a feeding groove 220 that matches the coating 7 and is provided on one side of the feeding hole 210. The feeding hole 210 is used to input the wire 6 and the feeding groove 220 is used to input the coating 7.
[0041] Special feed holes 210 and feed grooves 220 are designed for wire 6 and sheath 7 respectively, which can ensure the stability and accuracy of both during input, reduce errors and interference between them during processing, make it easier for operators to load and monitor, and improve work efficiency.
[0042] Furthermore, such as Figure 1 As shown, the feed trough 220 has a first groove 221 and a second groove 222 on both sides facing the feed hole 210.
[0043] The first groove 221 and the second groove 222 prevent the coating material 7 from lifting up on both sides and scraping the feeding groove during the coating process guided by the coating structure 4, effectively reducing the damage of the coating material 7 and improving product quality.

Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
