Abstract

This application relates to a wrapping die for a high-speed wrapping machine, belonging to the technical field of wrapping machines. It includes a base, on which a first component and a second component are sequentially arranged along the wire core conveying direction. The first and second components share a flanged wrapping hole for the wire core and wrapping tape to pass through. The diameter of the flanged wrapping hole gradually decreases along the wire core conveying direction, and its inner peripheral wall has a smooth curved surface. The flanged wrapping hole includes a C-shaped hole on the first component and a 6-shaped hole on the second component. The C-shaped hole forces the two sides of the wrapping tape cross-section to bend into an arc shape. The 6-shaped hole is used to compress the sides of the wrapping tape bent by the C-shaped hole, causing the two sides of the wrapping tape to overlap and adhere, ultimately completely covering the wire core. This application effectively avoids the wire core from being easily squeezed, wrinkling, lifting, or piling up, thus affecting the adhesion and bonding strength between the wrapping tape and the wire core, and improving the product's anti-interference ability.

Description

Technical Field

[0001] This application relates to the field of tape wrapping machine technology, and in particular to a tape wrapping mold for a high-speed tape wrapping machine. Background Technology

[0002] In the production and processing of wires and cables, the conductors are inseparable from the wrapping of the cable, and the cable wrapping layer is directly related to the mechanical properties, service life, and safety performance of the cable. The wrapping of the cable is generally divided into two methods: wrapping around the conductor and wrapping longitudinally.

[0003] The commonly used principle structure of aircraft molds in existing technology is as follows: the aircraft mold is equipped with a wrapping channel, one end of which is open, and the other end of which has a tapered hole. The wire core and the wrapping tape wrap around the wire core as they pass through the tapered hole. In addition, after wrapping the wire core, ground wires parallel to the wire core are usually added to both sides of the wrapping tape, and finally, the two ground wires and the wrapping tape are wound together using tape or adhesive tape.

[0004] In the process of developing this application, it was found that the technology has at least the following problems: when using the aircraft mold in this technology, the wire core is easily squeezed by the tapered hole, resulting in wrinkling, lifting or partial accumulation, which leads to a small fit and adhesion between the wrapping tape and the wire core, thereby reducing the product's anti-interference ability. Utility Model Content

[0005] In order to minimize the risk of wrinkling, lifting, or piling of the wire core due to compression, which would affect the fit and adhesion between the wrapping tape and the wire core and improve the product's anti-interference capability, this application provides a wrapping tape mold for a high-speed wrapping machine.

[0006] The technical solution provided in this application for a high-speed tape wrapping machine is as follows:

[0007] A wrapping die for a high-speed wrapping machine includes a base. A first component and a second component are sequentially arranged on the base along the wire core conveying direction. The first and second components share a flanged wrapping hole for the wire core and wrapping tape to pass through. The diameter of the flanged wrapping hole gradually decreases along the wire core conveying direction, and its inner circumferential wall has a smooth curved surface. The flanged wrapping hole includes a C-shaped hole on the first component and a 6-shaped hole on the second component. The C-shaped hole forces both sides of the wrapping tape cross-section to bend into an arc shape. The 6-shaped hole is used to compress the sides of the wrapping tape bent by the C-shaped hole, causing the two sides of the wrapping tape to overlap and adhere, ultimately completely covering the wire core.

[0008] By adopting the above technical solution, during the process of the wire core and wrapping tape passing through the flanged wrapping hole, the diameter of the flanged wrapping hole gradually decreases along the wire core conveying direction, and the inner peripheral wall is a smooth curved surface. This allows for gradual bending and wrapping of the wrapping tape, reducing the severe compression of the wrapping tape. This lowers the possibility of wrinkling, lifting, or partial accumulation of the wire core, improving the fit and adhesion between the wrapping tape and the wire core, and thus enhancing the product's anti-interference capability. Furthermore, the C-shaped hole, through its gradual shape change, first bends the two sides of the wrapping tape into an arc shape, preparing for the subsequent overlapping and bonding of the two sides of the wrapping tape using the 6-shaped hole. This step-by-step wrapping process makes the wrapping process more stable and reliable.

[0009] Preferably, the two components are provided with an end component at the end opposite to one component, and the end component has a through hole that communicates with the flange hole. The diameter of the through hole is less than or equal to the minimum diameter of the flange hole.

[0010] By adopting the above technical solution, the outlet hole can further shape and limit the wire core and wrapping tape after the edge is wrapped, ensuring that the wrapping tape can be tightly wrapped on the wire core, reducing loosening after wrapping and improving the wrapping quality of the product.

[0011] Preferably, the sidewalls of the first and second components are also provided with side holes for grounding transmission, and the side holes are located on both sides of the flange hole.

[0012] By adopting the above technical solution, the side hole provides a channel for the transmission of the ground wire, enabling the ground wire to be transmitted synchronously with the wire core and the wrapping tape. This facilitates the subsequent integration of the ground wire with the wrapping tape and the wire core, simplifies the production process, and improves production efficiency.

[0013] Preferably, the end of the end component is provided with a limiting hole that corresponds one-to-one with the side hole. The limiting hole is used for the ground wire to pass through, and there is an angle between the two limiting holes and the outlet hole. The angle of the angle is a preset angle.

[0014] By adopting the above technical solution, the limiting hole can guide the ground wire, so that the ground wire meets the wire core and the wrapping tape at a preset angle, and avoid the wire core and ground wire deviating from the predetermined transmission direction due to the tension during transmission, so that the two ground wires and the wire core are not on the same straight line in the cross section of the finished product after being wrapped with tape or adhesive tape.

[0015] Preferably, the bottom of the two components and the end component are integrally formed with a mounting block, and the base is provided with a mounting groove that matches the mounting block. The mounting block extends into the mounting groove and is fixedly connected by fasteners.

[0016] By adopting the above technical solution, the cooperation between the mounting block and the mounting groove achieves the initial positioning of the two components and the end component on the base. Then, by fixing with fasteners, the stability and firmness of the installation of the two components and the end component are ensured, while also facilitating disassembly and replacement.

[0017] Preferably, the mounting block is a dovetail block and the mounting groove is a dovetail groove. The dovetail groove is opened along the length direction of the base and passes through the base to one end near the end component. The mounting block can be inserted into the dovetail groove from the end that passes through the base to the one end near the end component.

[0018] By adopting the above technical solution, the dovetail block and dovetail groove have good guiding and anti-drop performance, which can ensure accurate alignment of the two parts and the end parts during installation, and prevent loosening or displacement during operation, thereby improving the overall stability of the mold.

[0019] Preferably, the fastener is a bolt, the bottom of the mounting block has a screw hole, and the bottom of the base has a plurality of locking holes that are through the bolt. The locking holes correspond one-to-one with the screw holes, and the bolt passes through the locking holes and extends into the screw holes to be threadedly connected to the screw holes.

[0020] By adopting the above technical solution, the bolt connection method is simple, reliable, and easy to operate. It can firmly fix the mounting block in the mounting groove, ensuring the stability of the connection between the two parts and the end parts and the base, and also facilitating subsequent maintenance and adjustment.

[0021] Preferably, a first positioning magnet is fixedly provided at one end of the two components near the first component and at one end of the end component near the two components, and a second positioning magnet is fixedly provided at one end of the first component near the two components and at one end of the two components near the end component, and the first positioning magnet and the second positioning magnet attract each other.

[0022] By adopting the above technical solution, the mutual attraction between the first positioning magnet and the second positioning magnet can play an auxiliary positioning role during the installation of the first component, the second component and the end component, so that they can be quickly and accurately aligned, improving installation efficiency, and also enhancing the tightness of the connection between the components.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up a base, a first component, a second component, a flanged wrapping hole, a C-shaped hole, and a 6-shaped hole, and utilizing the smooth curved surface of the flanged wrapping hole with a gradually decreasing diameter, while cooperating with the step-by-step action of the C-shaped hole and the 6-shaped hole, the wrapping tape is gradually bent and wrapped, reducing problems such as wrinkling and lifting caused by the compression of the wire core, improving the fit and adhesion between the wrapping tape and the wire core, and thus enhancing the product's anti-interference ability;

[0025] 2. By setting end components, outlet holes, and limiting holes, the outlet holes can further shape and limit the wrapped wire core and wrapping tape to ensure tight wrapping. The limiting holes can guide the ground wire to meet the wire core and wrapping tape at a preset angle, preventing the wire core and ground wire from deviating from the predetermined transmission direction due to tension during transmission, so that the two ground wires and wire core are not on the same straight line in the cross-section of the finished product after being wrapped with tape or adhesive tape.

[0026] 3. By setting up mounting blocks, mounting slots, bolts, screw holes, lock holes, first positioning magnets, and second positioning magnets, the cooperation between the dovetail blocks and dovetail slots achieves installation positioning and prevents detachment. The positioning magnets assist in the quick alignment of each component, improving installation efficiency. Bolt connections ensure stable installation and facilitate maintenance, improving connection reliability. Attached Figure Description

Detailed Implementation

[0034] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0035] This application discloses a tape-wrapping mold for a high-speed tape-wrapping machine. (Refer to...) Figure 1The device includes a base 1, on which a first component 11, a second component 12, and an end component 14 are sequentially arranged along the wire core conveying direction. The first component 11 is fixedly connected to the base 1, while the second component 12 and the end component 14 are detachably connected to the base 1. The first component 11 and the second component 12 share a flanged wrapping hole 13 for the wire core and wrapping tape to pass through. The diameter of the flanged wrapping hole 13 gradually decreases along the wire core conveying direction, and its inner peripheral wall has a smooth curved surface. Specifically, the flanged wrapping hole 13 includes a C-shaped hole 131 on the first component 11 and a 6-shaped hole 132 on the second component 12.

[0036] Reference Figure 1 and Figure 2 The C-shaped hole 131 forces the two sides of the tape cross section to be bent into an arc shape. The degree of bending of the C-shaped hole 131 at the end away from the two components 12 is less than the degree of bending of the C-shaped hole 131 at the end close to the two components 12.

[0037] Reference Figures 3 to 5 The type 6 hole 132 is used to compress the side of the strap that is bent by the type C hole 131, and to overlap and fit the two sides of the strap together, ultimately completely covering the wire core. At the end of the second component 12 near the first component 11, the curvature of the inner wall of one side of the type 6 hole 132 is greater than the curvature of the inner wall of the other side. At the end of the second component 12 near the end component 14, the type 6 hole 132 is circular. The end component 14 has a through hole 141 that communicates with the flanged wrapping hole 13, and the diameter of the through hole 141 is less than or equal to the minimum diameter of the flanged wrapping hole 13.

[0038] Reference Figures 1 to 5 As the wire core and wrapping tape pass through the wrapping tape mold, the C-shaped hole 131 gradually bends the two sides of the wrapping tape into an arc shape through its own shape change. Then, the 6-shaped hole 132 makes the two sides of the wrapping tape overlap and fit together, and finally the wrapping tape completely covers the wire core. The wrapping tape covering the wire core passes through the exit hole 141, thereby further stabilizing the shape of the wrapping tape.

[0039] To provide a suitable transmission channel for the ground wire, refer to Figure 1 and Figure 5 Both component 11 and component 12 have side holes 15 for grounding wire transmission on their side walls, located on both sides of the flanged wrapping hole 13. The end of component 14 has corresponding limiting holes 142 at its end, allowing the grounding wire to pass through. The two limiting holes 142 form an angle with the outlet hole 141, a preset angle. The limiting holes 142 guide the grounding wire, ensuring it meets the wire core and wrapping tape at a preset angle. This prevents the wire core and grounding wire from deviating from the intended transmission direction due to tension during transmission, thus ensuring that the two grounding wires and the wire core are not on the same straight line in the cross-section of the finished product after being wrapped with tape or adhesive tape.

[0040] To facilitate the installation and fixation of the two components 12 and the end component 14 on the base 1, and to ensure the stability and accuracy of the installation, refer to Figures 2 to 6 The bottom of the two components 12 and the end component 14 are integrally formed with a mounting block 2. The base 1 has a mounting groove 16 that matches the mounting block 2. The mounting block 2 extends into the mounting groove 16 and is fixedly connected by fasteners. The mounting block 2 is a dovetail block, and the mounting groove 16 is a dovetail groove. The dovetail groove is opened along the length direction of the base 1 and passes through the base 1 to one end near the end component 14. The mounting block 2 can be inserted into the dovetail groove from the end of the base 1 near the end component 14. The fasteners are bolts 17. The bottom of the mounting block 2 has a screw hole 21. The bottom of the base 1 has several locking holes 18 that pass through it. The locking holes 18 correspond one-to-one with the screw holes 21. The bolts 17 pass through the locking holes 18 and extend into the screw holes 21 to be threadedly connected to the screw holes 21. A first positioning magnet 3 is fixedly provided at one end of the two components 12 near the first component 11 and at one end of the end component 14 near the second component 12. A second positioning magnet 4 is fixedly provided at one end of the first component 11 near the second component 12 and at one end of the second component 12 near the end component 14. The first positioning magnet 3 and the second positioning magnet 4 attract each other.

[0041] Reference Figures 2 to 6 During installation, first, insert the dovetail blocks at the bottom of the two components 12 and the end component 14 into the dovetail grooves of the base 1, aligning them with the dovetail grooves. During insertion, the first positioning magnet 3 at the end of the two components 12 closest to the first component 11 attracts the second positioning magnet 4 at the end of the first component 11 closest to the two components 12, and the first positioning magnet 3 at the end of the end component 14 closest to the two components 12 attracts the second positioning magnet 4 at the end of the two components 12 closest to the end component 14, achieving initial precise alignment of the two components 12 and the end component 14. Then, insert the bolt 17 through the locking hole 18 at the bottom of the base 1 and thread it into the screw hole 21 at the bottom of the mounting block 2 to complete the fixing.

[0042] The implementation principle of a high-speed wrapping machine wrapping mold in this application embodiment is as follows: The wire core and the wrapping tape simultaneously enter the flange wrapping hole 13. First, they pass through the C-shaped hole 131 of a component 11. The C-shaped hole 131, with its gradually decreasing diameter and smooth inner wall structure, gradually bends the two sides of the wrapping tape into an arc shape. During this process, because there is no violent compression, the wire core is less likely to wrinkle, curl up, or pile up. Then, the wrapping tape, carrying the wire core, enters the 6-shaped hole 132 of a second component 12. The 6-shaped hole 132 continues to gently compress the bent sides of the wrapping tape, so that the two sides gradually overlap and fit together, ultimately achieving complete wrapping of the wire core. After wrapping, the wire core and the wrapping tape pass through the exit hole 141 of the end component 14. The exit hole 141 is further shaped to ensure that the wrapping tape fits tightly against the wire core. Simultaneously, the ground wire is transmitted through the side holes 15 of component 11 and component 12, and guided by the limiting hole 142 of end component 14. It then converges with the wrapped wire core and wrapping tape at a preset angle, ensuring accurate relative positioning of the wire core and the two ground wires after subsequent winding. This facilitates the wrapping machine's use of tape or adhesive tape to secure the wire core, wrapping tape, and ground wire after they have moved away from the wrapping mold. This minimizes the risk of wrinkles, curling, or accumulation of the wire core due to compression, which could affect the fit and adhesion between the wrapping tape and the wire core, thus improving the product's anti-interference capability.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
