One side of the conductive cloth is usually sticky, and the conductive cloth is coated on the wire through the sticky surface.

[0003] At present, the commonly used conductive cloth wrapping method is by rubbing, that is, first the conductive cloth is adhered to the surface of the wire, and then the conductive cloth is wrapped around the wire in circles by rubbing multiple times.

[0008] As a further solution of the present invention: the cloth wrapping assembly also includes a baffle, which can be against the side of the wire opposite to the roller when the roller rolls the conductive cloth, and the baffle and the pressure plate cooperate with each other to form a right-angle space for clamping the wire.

[0009] As a further solution of the present invention: the air nozzles on the pressing plate are arranged in sequence with equal intervals along the length direction of the wire, and the air nozzles are connected to the air pump.

[0010] As a further solution of the present invention: the pressure plate, the baffle plate and the roller are all movably mounted on the frame through corresponding telescopic rods, and the telescopic directions of the corresponding telescopic rods coincide with the movement directions of the pressure plate, the baffle plate and the roller respectively.

[0011] As a further solution of the present invention: elastic layers are arranged on the working surfaces of the pressure plate, the baffle plate and the roller.

[0012] As a further solution of the present invention: the tensioning assembly includes an annular frame installed on the frame and arranged horizontally, and two positioning grooves arranged opposite to each other are opened on the upper frame surface of the annular frame, and the two ends of the wire are respectively clamped in the positioning grooves; the notches of the two positioning grooves are arranged with pressure blocks, and the pressure blocks can press the wire in the positioning grooves and tighten the wire toward the two ends of the wire through friction force.

[0013] As a further solution of the present invention: a compression telescopic rod is installed on the frame, and the telescopic direction of the compression telescopic rod is arranged vertically; a tensioning telescopic rod is fixedly installed on the telescopic end of the compression telescopic rod, and the pressure block is fixedly installed on the telescopic end of the tensioning telescopic rod, and the telescopic direction of the tensioning telescopic rod is parallel to the length direction of the wire.

[0014] As a further solution of the present invention: the roller is rotatably installed on a swivel seat, the swivel seat is installed on the telescopic end of the rolling telescopic rod, and the telescopic direction of the rolling telescopic rod is perpendicular to the length direction of the wire.

[0015] As a further solution of the present invention: a blocking telescopic rod is fixedly installed on the frame, the baffle is installed on the telescopic end of the blocking telescopic rod, and the telescopic direction of the blocking telescopic rod is arranged vertically.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention can efficiently and evenly wrap the conductive cloth tightly around the flat wire circle by circle through the alternating cooperation of two sets of cloth wrapping components and the straightening effect of the tensioning component, thereby improving the accuracy and stability of the wrapping and ensuring good contact between the conductive cloth and the wire.

[0019] 2. The addition of the baffle forms a right-angle space with the pressure plate, which can not only effectively fix the position of the wire and prevent it from moving during the rolling process, but also ensure that the conductive cloth is smoother and wrinkle-free during rolling, thereby improving the wrapping quality and aesthetics.

[0020] 3. The air nozzles are arranged at equal intervals and connected to the air pump, so that the conductive cloth is evenly stressed during the bending process, making it easy to control the bending angle and position, ensuring the continuity and consistency of the conductive cloth wrapping and improving work efficiency.

[0021] 4. The pressure plate, baffle and roller are installed movably through telescopic rods, which can be flexibly adjusted according to the wire size and packaging requirements, improving the adaptability and versatility of the device, and also facilitating maintenance and repair.

[0022] 5. The elastic layer on the working surface can reduce the damage to the wire and the conductive cloth, while increasing the friction, ensuring that the conductive cloth can fit tightly on the wire during the rolling process, thereby improving the firmness and reliability of the wrapping.

[0023] 6. The tensioning component adopts a ring frame and positioning groove design, combined with the pressing effect of the pressure block, which can stably straighten the wire to prevent it from deflecting or loosening during the wrapping process, ensuring the accuracy and stability of the wrapping.

[0024] 7. The coordinated use of the compression telescopic rod and the tensioning telescopic rod enables the pressure block to flexibly adjust its position and pressure to meet the tensioning requirements of different wires, thereby improving the flexibility and practicality of the device.

[0025] 8. The roller is installed on the rotating seat and driven by the rolling telescopic rod, so that the roller can flexibly adjust the position and angle according to the needs, better adapt to the wrapping needs of the wire, and improve the uniformity and quality of the wrapping.

[0026] 9. The fixed installation and vertical telescopic direction design of the blocking telescopic rod enable the baffle to stably resist the opposite side of the roller, ensuring that the conductive cloth will not deviate or warp during the rolling process, thereby improving the flatness and aesthetics of the package.

[0027] 10. The fixed installation and vertical telescopic direction design of the tight telescopic rod enable the pressure plate to stably contact the wire and fit the conductive cloth tightly on it, ensuring the firmness and conductivity of the wrapping. At the same time, the flexibility of the tight telescopic rod also facilitates adjustment according to the size of the wire, improving the adaptability and versatility of the device.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1 to Figure 6 In an embodiment of the present invention, a conductive cloth wrapping device for a wire includes a frame 1 supported on the ground, and a tensioning component 2 and a cloth wrapping component 3 are installed on the frame 1.

[0037] The tensioning assembly 2 includes a rectangular annular frame 24 mounted on the frame 1, and the annular frame 24 is in a horizontal state. Positioning grooves 241 are provided at the center positions of the two opposite frame edges of the annular frame 24, and the shape of the positioning grooves 241 is adapted to the shape of the wire 4, so that the two ends of the wire 4 can be clamped in the positioning grooves 241. A clamping telescopic rod 21 is arranged above each positioning groove 241, and the telescopic direction of the clamping telescopic rod 21 is arranged vertically. A tensioning telescopic rod 22 is fixedly installed on the telescopic end of the tensioning telescopic rod 21, and a pressing block 23 is fixedly installed on the telescopic end of the tensioning telescopic rod 22, and the telescopic direction of the tensioning telescopic rod 22 is parallel to the length direction of the wire 4. When in use, the tensioning telescopic rod 21 is extended, driving the tensioning telescopic rod 22 to move downward and causing the pressing block 23 to be pressed on the wire 4 in the positioning groove 241; finally, the tensioning telescopic rod 22 is shortened, and under the action of friction, the wire 4 is straightened to both ends.

[0038] There are two groups of cloth wrapping components 3, which are respectively located on the upper and lower sides of the flat wire 4. The cloth wrapping component 3 includes a telescopic rod 31 fixedly mounted on the frame 1, and the telescopic direction of the telescopic rod 31 is arranged vertically. A pressing plate 311 is fixedly mounted on the telescopic end of the telescopic rod 31, and the pressing plate 311 has a certain thickness, and the pressing plate 311 is in the shape of a rectangular parallelepiped. The length direction of the pressing plate 311 is parallel to the length direction of the wire 4, so that the conductive cloth 5 can be pressed on the section to be wrapped of the wire 4. An air nozzle 3111 is also provided in the non-crimping area of ​​the pressing plate 311, and each air nozzle 3111 is arranged on the pressing plate 311 at equal intervals along the length direction of the wire 4, and each nozzle is connected to the air pump. When the pressing plate 311 presses the conductive cloth 5 on the wire 4, at this time, because the conductive cloth 5 has a certain toughness, its part outside the wire 4 is still in a horizontal state. At this time, the air pump is turned on, and the air nozzle 3111 blows air from top to bottom to the conductive cloth 5 outside the wire 4, so as to bend it downward at about 45 degrees or any angle.

[0039] The frame 1 is also provided with a rolling telescopic rod 33, and the telescopic direction of the rolling telescopic rod 33 is arranged horizontally. A rotating seat 331 is fixedly installed on the telescopic end of the rolling telescopic rod 33, and each roller 322 is rotatably installed on the rotating seat 331. The rotation axis of the roller 322 is parallel to the wire 4. When the conductive cloth 5 is blown and kept in a bent state under the continuous blowing of the air nozzle 3111, the rolling telescopic rod 33 is extended to push the roller 322 to approach the bent conductive cloth 5. The roller 322 contacts the windward surface of the conductive cloth 5, and pushes the conductive cloth 5 to continue to bend and bond with the other side of the wire 4. At the same time, the roller 322 repeatedly rolls the conductive cloth 5 under the reciprocating telescopic action of the rolling telescopic rod 33. At this time, the air nozzle 3111 is closed to improve the bonding degree of the remaining wires 4. During the entire single blowing, bending and rolling process, the conductive cloth 5 located outside the wire 4 is bent 180 degrees, and while being wrapped around the outside of the wire 4, the conductive cloth 5 is again in a horizontal state for the next round of blowing, bending and rolling. Through multiple rounds of blowing, bending and rolling, the entire conductive cloth 5 can be wrapped around the wire 4 in circles.

[0040] In the process of rolling by the roller 322, in order to prevent the wire 4 from deviating to one side, a blocking telescopic rod 32 installed on the frame 1 is arranged on the opposite side of the roller 322, and the telescopic direction of the blocking telescopic rod 32 is arranged vertically. A baffle 321 is fixedly installed on the telescopic end of the blocking telescopic rod 32 to drive the baffle 321 to extend toward the wire 4, and block the other side of the wire 4 before rolling, and at the same time cooperate with the pressing plate 311 to form a right-angle space for clamping the wire 4. At the same time, the lower end surface of the baffle 321 and the lower side surface of the wire 4 are basically located in the same horizontal plane, so that the roller 322 can roll the conductive cloth 5 on the lower end surface of the baffle 321, and then fix the wire 4, so that the wire 4 remains motionless during the repeated rolling process of the roller 322.

[0041] The specific use process of the present invention is as follows:

[0042] Working status 1:

[0043] like Figure 3 As shown, the two ends of the flat wire 4 are placed in the positioning groove 241, and the compression telescopic rod 21 and the tension telescopic rod 22 are started in sequence to make the wire 4 in a horizontal tensioned state. Then the edge of the conductive cloth 5 is aligned with the wire 4 and pressed against the wire 4. Then the abutting telescopic rods on the upper and lower sides of the wire 4 are opened at the same time, the two abutting telescopic rods are extended, and the two pressing plates 311 are used to perform a secondary compression on the wire 4 and the conductive cloth 5 from the upper and lower sides of the wire 4, once again improving the strength of the initial bonding between the conductive cloth 5 and the wire 4. Then the air nozzle 3111 on the upper side is opened to blow air to the conductive cloth 5 to bend the conductive cloth 5 by 45 degrees, or a desired angle.

[0044] Working status 2:

[0045] like Figure 4 As shown, after the conductive cloth 5 is bent to a set angle by the air nozzle 3111 on the upper side, the contact telescopic rod on the lower side retracts, and the blocking telescopic rod 32 on the upper side extends. At this time, the lower pressure plate 311 is reset, and the upper baffle 321 extends to the left side of the wire 4 and abuts against the left side of the wire 4. Then the rolling telescopic rod 33 on the right side is started, so that the roller 322 abuts against the bending part of the conductive cloth 5 and the conductive cloth 5 continues to bend; at the same time, it is bonded to the lower side of the wire 4 and bonded to the bottom surface of the upper baffle 321; then the roller 322 is repeatedly rolled several times to improve the tightness of the bonding.

[0046] Working status three:

[0047] like Figure 5 As shown, after the right roller 322 rolls several times, the right roller 322 is reset, and the upper baffle 321 is reset at the same time. Then the lower pressing plate 311 is pressed against the lower side of the wire 4 again to cooperate with the upper pressing plate 311 to squeeze the wire 4 and the conductive cloth 5 to improve the tightness of the bonding again. Then the lower air nozzle 3111 is opened to blow air to the conductive cloth 5 to bend it to a set angle.

[0048] Working status 4:

[0049] like Figure 6 As shown, after the conductive cloth 5 is bent to a set angle by the air nozzle 3111 on the lower side, the upper contact telescopic rod retracts, and the lower blocking telescopic rod 32 extends. At this time, the upper pressure plate 311 is reset, and the lower baffle 321 extends to the right side of the wire 4 and abuts against the right side of the wire 4. Then the rolling telescopic rod 33 on the left side is started, so that the roller 322 abuts against the bending part of the conductive cloth 5, and the conductive cloth 5 continues to bend; at the same time, it is bonded to the upper side of the wire 4, and it is bonded to the bottom surface of the lower baffle 321; then the roller 322 is repeatedly rolled several times to improve the tightness of the bonding. After that, the roller 322 is reset.

[0050] Then, according to the working state, one to four cycles of blowing and rolling are performed to wrap the conductive cloth 5 around the wire 4 one circle at a time. Figure 6 When there is still a little bit left outside the wire 4, it can no longer be rolled by the roller 322 because the blowing force of the air nozzle 3111 is increased to bend and press this part onto the wire 4.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
