Description

Technical Field

[0001] This utility model relates to the field of copper flat wire winding technology, specifically a copper flat wire winding device wrapped with a single glass filament polyester film. Background Technology

[0002] Single-glass fiber polyester film-wrapped copper flat wire is a widely used cable in electrical equipment, and winding is a crucial step in its production. Existing winding devices struggle to maintain stable cable tension during the winding process, leading to inconsistent winding tightness and affecting the winding quality.

[0003] For example, the wire winding device with application number CN202323201040.6 belongs to the technical field of wire production equipment. It includes a base plate, a first support mounted on the top of the base plate, a winding drum rotatably mounted on the front of the first support, and a motor for driving the winding drum mounted on the back of the base plate. A second guide mechanism is fixedly mounted on the top of the base plate on one side of the first support, and a first guide mechanism is fixedly mounted on the top of the base plate on one side of the second guide mechanism. A first telescopic rod and a second telescopic rod are symmetrically mounted on the top of the base plate between the first guide mechanism and the second guide mechanism. This utility model, through the arrangement of the first telescopic rod, the second telescopic rod, the first crossbar, and the roller, enables the roller to move up and down during use via the first and second telescopic rods, thereby tightening the wire passing through the bottom of the roller and preventing the wound wire from becoming loose.

[0004] The aforementioned patent employs a fixed spacing design, making it difficult to flexibly adjust the rollers according to different specifications during winding. When it is necessary to replace rollers of different sizes to adapt to the winding requirements of different specifications of wires, it is often necessary to use complex disassembly tools for cumbersome disassembly and assembly operations. This not only consumes a lot of time and manpower but also seriously affects the efficiency of production preparation, making it impossible to quickly respond to diverse production needs. This leads to increased equipment downtime. Furthermore, during the winding process, problems such as lateral offset and uneven winding can easily cause stacking deformation, resulting in irregular appearance and unstable quality of the finished product, which in turn leads to a high scrap rate, increases the company's production costs, and reduces economic benefits.

[0005] Therefore, we propose a single glass filament polyester film wrapping and copper flat wire winding device to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a single glass filament polyester film wrapping copper flat wire winding device to solve the problem mentioned in the background art that the existing winding device is difficult to flexibly adjust according to different specifications of rollers and the winding is uneven.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a single glass filament polyester film-wrapped copper flat wire winding device, comprising a base frame, an mounting frame fixedly connected to one end of the base frame, a motor fixedly connected to the mounting frame, a coupling fixedly connected to the output end of the motor, a pulley one fixedly sleeved on the outer ring of the coupling, a rotating shaft rotatably connected to the base frame, a pulley two fixedly sleeved on the outer ring of the rotating shaft, and a belt wound between the pulley one and the pulley two;

[0008] The base frame is equipped with an adjustable winding assembly and a guide assembly. The adjustable winding assembly includes a rotating roller fixedly connected to the end of the coupling. A turntable is rotatably mounted on the outer ring of the rotating roller. An arc-shaped groove is opened on the turntable. A winding roller is slidably connected in the arc-shaped groove. A sleeve roller is sleeved on the outer ring of the winding roller. A wrapped copper flat wire body is wound and connected on the sleeve roller.

[0009] Preferably, the outer ring of the rotating roller is fixedly sleeved with a railing, the rotating roller has a first groove, the rotating disk has a second groove, and the first groove and the second groove are connected.

[0010] Preferably, a fixed rod is fixedly connected inside the rotating roller, an electromagnet is fixedly fixed on the top surface of the fixed rod, a telescopic rod is slidably connected inside the fixed rod, a permanent magnet is fixedly connected to the top of the telescopic rod, a brake pad is fixedly connected to the top surface of the permanent magnet, and the brake pad is in contact with the inner wall of the turntable.

[0011] Preferably, a spring is fitted around the outer ring of the telescopic rod, and the two ends of the spring are fixedly connected to the top surface of the electromagnet and the bottom surface of the permanent magnet, respectively.

[0012] Preferably, the guide assembly includes a reciprocating screw fixedly connected to the end of the rotating shaft, a slide is threaded onto the reciprocating screw, a telescopic column is fixedly connected between the slide and the base frame, two conveying rollers are rotatably connected to the side wall of the slide, compression springs are fixedly connected to the side walls of the two conveying rollers, a limit wheel is slidably connected to the conveying rollers, and the limit wheel is elastically connected to the conveying rollers through a compression spring.

[0013] Preferably, the two sides of the wrapped copper flat wire body are in contact with the sidewalls of the limiting wheel and the conveying wheel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model achieves rapid switching between the locking states of the turntable and the rotating rollers through the coordinated design of electromagnets, permanent magnets, springs, and brake pads. When it is necessary to adjust the spacing of the winding rollers, simply energizing the electromagnet releases the turntable restriction, allowing operators to easily and manually adjust the spacing of multiple winding rollers to precisely adapt to different specifications of roller sleeves. Compared to traditional fixed-structure winding devices, this device greatly reduces the disassembly and assembly time and operational difficulty when changing roller sleeves, improves production preparation efficiency, can quickly respond to diverse production needs, and reduces equipment downtime.

[0016] 2. This utility model achieves automatic lateral guidance of the wrapped copper flat wire body through the threaded transmission of the reciprocating screw and the slide. With the elastic adjustment structure of the limit wheel and the pressure spring, it can adaptively adjust the position of the cable. During the winding process, the lateral movement of the conveyor wheel and the rotation of the sleeve roller are closely coordinated to ensure that the wrapped copper flat wire body is wound evenly and orderly, effectively avoiding problems such as cable deviation, winding chaos and stacking deformation. This results in a neat appearance and stable quality of the wound product, and greatly reduces the scrap rate caused by winding quality problems. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-6 A single glass filament polyester film-wrapped copper flat wire winding device includes a base frame 1, an mounting frame 2 fixedly connected to one end of the base frame 1, a motor 3 fixedly connected to the mounting frame 2, a coupling 4 fixedly connected to the output end of the motor 3, a pulley 5 fixedly sleeved on the outer ring of the coupling 4, a rotating shaft 71 rotatably connected to the base frame 1, a pulley 7 fixedly sleeved on the outer ring of the rotating shaft 71, and a belt 6 wound between the pulley 5 and the pulley 7.

[0026] An adjustable winding assembly 8 is installed on the base frame 1. The adjustable winding assembly 8 includes a rotating roller 82 fixedly connected to the end of the coupling 4. A turntable 83 is rotatably mounted on the outer ring of the rotating roller 82. An arc-shaped groove 84 is provided on the turntable 83. A winding roller 85 is slidably connected in the arc-shaped groove 84. A sleeve roller 9 is sleeved on the outer ring of the winding roller 85. The sliding design of the arc-shaped groove 84 and the winding roller 85 provides flexible operating space for the installation and disassembly of the sleeve roller 9. A wrapped copper flat wire body 11 is wound and connected on the sleeve roller 9.

[0027] The outer ring of the rotating roller 82 is fixedly sleeved with a frame 81. The rotating roller 82 has a groove 821, and the turntable 83 has a groove 831. The groove 821 and the groove 831 are connected.

[0028] A fixed rod 822 is fixedly connected inside the rotating roller 82. An electromagnet 823 is fixedly fixed on the top surface of the fixed rod 822. A telescopic rod 824 is slidably connected inside the fixed rod 822. A permanent magnet 825 is fixedly connected to the top of the telescopic rod 824. A brake pad 826 is fixedly connected to the top surface of the permanent magnet 825. The brake pad 826 is in contact with the inner wall of the turntable 83.

[0029] A spring 827 is fitted around the outer ring of the telescopic rod 824. The two ends of the spring 827 are fixedly connected to the top surface of the electromagnet 823 and the bottom surface of the permanent magnet 825, respectively.

[0030] Specifically, when winding the copper flat wire body 11, the spacing between multiple winding rollers 85 is adjusted according to requirements so that it can be adapted to the specifications of the winding roller 9 of the copper flat wire body 11. In the initial state, the spring 827 is in a stretched state. At this time, the telescopic rod 824 extends upward, and the permanent magnet 825 and brake pad 826 at its top extend synchronously. The brake pad 826 is in a state of contact with the inner wall of the groove 831 of the turntable 83. At this time, under the action of the brake pad 826, the roller 82 and the turntable 83 are locked together, and the turntable 83 cannot rotate on the outer ring of the roller 82.

[0031] During adjustment, electromagnet 823 is first energized. When energized, electromagnet 823 attracts permanent magnet 825. Under this attraction, permanent magnet 825 moves downwards. As it moves downwards, the brake pad 826 on its top surface separates from the turntable 83. Simultaneously, the telescopic rod 824 fixed to the bottom of permanent magnet 825 slides inwards towards the fixed rod 822, stretching spring 827. At this point, brake pad 826 is no longer in contact with turntable 83, and turntable 83 is released from its relative constraint, allowing it to rotate. Then, the operator manually rotates turntable 83 to make it rotate... As the rotating roller 82 rotates, the arc groove 84 on the turntable 83 shifts, and the take-up roller 85 installed in the arc groove 84 moves under the rotational thrust of the turntable 83. Since multiple take-up rollers 85 and arc grooves 84 are provided, multiple take-up rollers 85 rotate synchronously, and the distance between multiple take-up rollers 85 is adjusted, thereby realizing the synchronous adjustment of the spacing between multiple take-up rollers 85. This allows for flexible adaptation to the installation requirements of different specifications of sleeve rollers 9, improving the applicability and ease of operation of the device.

[0032] After the spacing of the take-up rollers 85 is adjusted, the electromagnet 823 is de-energized. At this time, the device enters the preparation state for stable take-up. After losing the electromagnetic attraction of the electromagnet 823, the stretched spring 827 quickly releases its elastic potential energy. The upward elastic force of the spring 827 pushes the telescopic rod 824 to extend outward toward the fixed rod 822. The permanent magnet 825 connected to the top of the telescopic rod 824 moves upward in sync. The permanent magnet 825 drives the brake pad 826 to gradually approach the inner wall of the groove 831 of the turntable 83. As the permanent magnet 825 continues to rise, the fit between the brake pad 826 and the inner wall of the groove 831 of the turntable 83 gradually increases until they are tightly fitted.

[0033] When the brake pad 826 is fully in contact with the inner wall of the groove 831 of the turntable 83, under the combined action of friction and mechanical limiting, the turntable 83 and the roller 82 re-form a stable locking structure, and the turntable 83 can no longer rotate freely around the roller 82. At this time, the motor 3 starts, and the power is transmitted to the roller 82 through the coupling 4. The roller 82 can then drive the turntable 83, the take-up roller 85 and the sleeve roller 9 to rotate synchronously through the cooperation of the frame 81 and the groove of the turntable 83, and begin to perform a stable take-up operation on the wrapped copper flat wire body 11. Since the spacing of the take-up roller 85 has been adapted according to the specifications of the sleeve roller 9 during the adjustment process, the sleeve roller 9 can remain stable during the take-up process, ensuring that the wrapped copper flat wire body 11 is evenly wound, giving full play to the advantages of the device in flexible adjustment and efficient take-up.

[0034] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-2 A guide assembly 10 is installed on the base frame 1. The guide assembly 10 includes a reciprocating screw 101 fixedly connected to the end of the rotating shaft 71. A slide block 102 is threaded onto the reciprocating screw 101. The cooperation between the reciprocating screw 101 and the slide block 102 realizes the automatic lateral guidance of the wrapped copper flat wire body 11. A telescopic column 103 is fixedly connected between the slide block 102 and the base frame 1. Two conveying rollers 104 are rotatably connected to the side wall of the slide block 102. Compression springs 105 are fixedly connected to the side wall of the two conveying rollers 104. A limit wheel 106 is slidably connected to the conveying rollers 104. The limit wheel 106 and the conveying rollers 104 are elastically connected by the compression spring 105. The design of the limit wheel 106 and the compression spring 105 can adaptively adjust the position of the wrapped copper flat wire body 11, ensuring that it always maintains a neat arrangement during the winding process, avoiding tangling and improving the winding quality.

[0035] The two sides of the wrapped copper flat wire body 11 are in contact with the side wall of the limiting wheel 106 and the side wall of the conveying wheel 104.

[0036] Specifically, during the winding operation of the wrapped copper flat wire body 11, it is first precisely inserted between the two conveyor rollers 104. During the insertion process, the wrapped copper flat wire body 11 contacts and applies pressure to the limiting roller 106, causing the limiting roller 106 to slide along the conveyor roller 104, while simultaneously compressing the compression spring 105. Once the wrapped copper flat wire body 11 is fully in place, the compression spring 105 quickly returns to its original position due to its elastic potential energy, pushing the limiting roller 106 to tightly fit against both sides of the wrapped copper flat wire body 11, firmly clamping it between the limiting roller 106 and the conveyor roller 104, ensuring that the wrapped copper flat wire body 11 remains in the center position during the conveying process, effectively preventing deviation.

[0037] After positioning the wrapped copper flat wire body 11 is completed, the motor 3 is started. The power output of the motor 3 is transmitted to pulley 5 via coupling 4. Pulley 5 drives pulley 7 to rotate via belt 6, which in turn drives the rotating shaft 71 to rotate. The reciprocating screw 101 installed on the end of the rotating shaft 71 rotates synchronously. Utilizing the principle of screw transmission, it drives the slide 102 to make linear reciprocating motion along the screw. The two conveying wheels 104 on the slide 102 also move laterally, realizing automatic lateral guidance of the wrapped copper flat wire body 11. At the same time, the coupling 4 drives the rotating roller 82 to rotate. The rotating roller 82, through the cooperation of the railing 81 and the groove on the turntable 83, drives the turntable 83 and the sleeve roller 9 installed on the outer ring of the take-up roller 85 to rotate and rewind synchronously. During this process, the lateral movement of the conveying roller 104 and the rotation and rewinding of the sleeve roller 9 work together to enable the copper flat wire body 11 to be wound evenly and orderly on the outer ring of the sleeve roller 9, effectively avoiding problems such as uneven winding and stacking deformation caused by concentrated winding in the same position, and significantly improving the winding quality and efficiency.

[0038] The application scenarios of this winding device are not limited to the winding process of copper flat wire wrapped with single glass fiber polyester film in wire and cable manufacturing enterprises. With the guide component 10 and flexible and adjustable winding structure, it also shows good adaptability and versatility for winding operations of various cable and wire products, and can meet the high-efficiency winding needs of cables of different materials and specifications. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
