Description

Technical Field

[0001] This utility model relates to the field of photovoltaic welding strip processing, and in particular to a low-energy wire feeding device. Background Technology

[0002] In the process of welding strip processing, the copper wire used is transferred from a special I-beam reel to a special wire feeding frame after being wound up, and then fed into the copper strip rolling forming device for processing. Due to the high density of the copper wire itself, the overall mass of the I-beam reel after winding is relatively large, making it difficult to rotate with the wire feeding action during the feeding process. In order to improve the uniformity of the feeding action, a special wire feeding motor is usually installed on the traditional wire feeding frame. The wire feeding motor is connected to the wire feeding shaft on the wire feeding frame that passes through the center positioning hole of the I-beam reel, driving the I-beam reel to rotate. However, as the amount of copper wire on the I-beam reel decreases, the overall weight decreases, the load on the wire feeding motor decreases, and the motor speed will fluctuate, affecting the forming quality of the copper strip. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a wire feeding device that can reduce energy consumption and lower operating costs.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A low-energy-consumption wire feeding device is provided. The wire feeding reel used in the low-energy-consumption wire feeding device is an H-beam reel. The low-energy-consumption wire feeding device includes: a wire feeding frame, a reel seat, and a wire feeding cover. The reel seat is fixed directly below the center of the wire feeding frame. A set of steering guide wheels is suspended above the wire feeding frame. The H-beam reel is vertically placed on the reel seat. One side baffle of the H-beam reel presses against the upper surface of the reel seat. The wire feeding cover is installed on the other side baffle of the H-beam reel. The wire feeding cover extends from top to bottom... An upper clamping plate, a lower clamping plate, and a rotating cover plate are arranged concentrically below. A line-blocking brush is held between the upper and lower clamping plates. The lower clamping plate is fixed to the top of the rotating cover plate. The diameters of the upper and lower clamping plates are smaller than the diameter of the rotating cover plate. The outer diameter of the line-blocking brush is larger than the diameter of the rotating cover plate. A ball bearing is installed in the middle of the bottom of the rotating cover plate. The outer diameter of the ball bearing matches the inner diameter of the center positioning hole in the center of the baffles on both sides of the I-beam wheel. The diameter of the rotating cover plate is larger than the diameter of the baffles, and the edge of the rotating cover plate has an arc surface structure.

[0005] In a preferred embodiment of the present invention, a positioning protrusion is provided at the top center of the wheel seat, and the maximum outer diameter of the positioning protrusion is in clearance fit with the inner diameter of the center positioning hole of the I-beam wheel.

[0006] In a preferred embodiment of this utility model, the diameter of the rotating cover plate is 3-5 cm larger than the diameter of the I-beam wheel baffle. A concentric circular groove is provided at the bottom of the rotating cover plate. The ball bearing is installed at the center of the circular groove. The inner diameter of the circular groove is 0.5-1 cm larger than the diameter of the I-beam wheel baffle. The groove depth of the circular groove is not less than the thickness of the baffle.

[0007] In a preferred embodiment of the present invention, a lifting ring is also installed on the top of the wire feeding cover.

[0008] In a preferred embodiment of this invention, the baffle brush is composed of nylon fibers evenly clamped circumferentially between the upper and lower clamping plates. The diameter of the nylon fibers is 0.5–2 mm, and the length of the nylon fibers extending beyond the rotating cover plate after clamping is 5–8 cm. The distance between any two adjacent nylon fibers is 1–3 cm.

[0009] The beneficial effects of this utility model are as follows: This utility model is a reconstruction of the existing copper wire feeding mechanism. By redesigning the placement of the I-beam reel and the corresponding feeding structure during feeding, and eliminating the dedicated anti-wire motor in the entire structure, the resistance during copper wire unwinding is significantly reduced when the reel is placed longitudinally in actual application. The feeding and unwinding actions can be completed by the tension naturally generated in the previous process, without the need for additional motor assistance. This not only reduces the manufacturing cost of the entire feeding device but also saves on electricity costs during operation. Moreover, since the feeding speed is only related to the tension in the previous process, the fluctuation of the feeding speed is significantly reduced, and the dimensional stability of the final copper strip is significantly improved.

[0015] Rings. Detailed Implementation

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0017] Please see Figure 1 and Figure 2 The embodiments of this utility model include:

[0018] A low-energy wire feeding device, wherein the wire feeding reel used in the low-energy wire feeding device is an I-beam reel 2, the low-energy wire feeding device includes: a wire feeding frame 5, a reel seat 3, and a wire feeding cover 7, the reel seat 3 is fixed directly below the center of the wire feeding frame 5, a steering guide wheel assembly 6 is suspended above the wire feeding frame 5, the I-beam reel 2 is vertically placed on the reel seat 3, one side baffle of the I-beam reel 2 presses against the upper surface of the reel seat 3, and the wire feeding cover 7 is installed on the other side baffle of the I-beam reel 2; the wire feeding cover 7 is concentrically arranged from top to bottom with an upper clamping plate 704, a lower clamping plate 703, and a rotating cover plate 701, the upper clamping plate... A line-blocking brush 705 is clamped between the upper clamping plate 704 and the lower clamping plate 703. The lower clamping plate 704 is fixed to the top of the rotating cover plate 701. The diameters of the upper clamping plate 703 and the lower clamping plate 704 are smaller than the diameter of the rotating cover plate 701. The outer diameter of the line-blocking brush 705 is larger than the diameter of the rotating cover plate 701. A ball bearing 702 is installed in the middle of the bottom of the rotating cover plate 701. The outer diameter of the ball bearing 702 matches the inner diameter of the center positioning hole of the center of the baffles on both sides of the I-beam wheel 2. The diameter of the rotating cover plate 701 is larger than the diameter of the baffle, and the edge of the rotating cover plate 701 is an arc surface structure.

[0019] The wheel base 3 has a positioning protrusion 4 at its top center. The maximum outer diameter of the positioning protrusion 4 is clearance-fitted with the inner diameter of the center positioning hole of the I-beam wheel 2. By setting the positioning protrusion 4, the placement position of the I-beam wheel 2 can be quickly positioned during placement, and the I-beam wheel 2 can be fixed to prevent it from being pulled as a whole in the later stage when there are fewer copper wires 1, which would affect the stability of the product.

[0020] The diameter of the rotating cover plate 701 is 3-5 cm larger than the diameter of the I-beam wheel baffle, typically 5 cm in practice. A concentric circular groove is provided at the bottom of the rotating cover plate 701. The ball bearing 702 is installed at the center of the circular groove. The inner diameter of the circular groove is 0.5-1 cm larger than the diameter of the I-beam wheel baffle, typically 1 cm in practice. The depth of the circular groove is equal to the thickness of the baffle. To prevent the copper wire 1 from rubbing against the outer edge of the baffle during unwinding, the rotating cover plate 701 should be slightly larger than the baffle, but not too large, otherwise the angle would be too large, easily increasing the unwinding resistance and hindering unwinding. The circular groove in the rotating cover plate 701 serves two purposes: firstly, to ensure the center of gravity of the rotating cover plate 701 falls in the middle of the baffle, improving the stability of the rotating cover plate 701 and preventing it from easily falling off during rotation; secondly, to reduce the influence of the baffle thickness on unwinding, further reducing unwinding resistance.

[0021] The top of the wire laying cover 7 is also equipped with a lifting ring 706, which facilitates the installation and removal of the entire wire laying cover 7 by on-site personnel.

[0022] The wire-blocking brush 705 is composed of nylon fibers evenly clamped circumferentially between the upper clamping plate 704 and the lower clamping plate 703. The diameter of the nylon fibers is 0.5-2mm, but in practice, nylon fibers of about 0.8mm are generally selected, as this diameter provides the best strength matching with the wire tension. The length of the nylon fibers after clamping extends 5-8cm beyond the rotating cover plate. The distance between any two adjacent nylon fibers is 1-3cm, and in practice, it is generally 2cm. The purpose of installing the wire-blocking brush 705 is to prevent the copper wire 1 from sliding too quickly relative to the edge of the rotating cover plate 701 during unwinding, which could lead to overall slippage and cause the tension of the copper wire 1 to decrease too quickly or even stall during subsequent processing, seriously affecting product quality. After the wire-blocking brush 705 is added, during the unwinding process, the copper wire 1 will rotate along the rotating cover plate 701 and press against the nylon fiber, thereby pushing the entire wire-blocking plate 7 to rotate. Since the strength of the nylon fiber is limited, it will automatically bend when subjected to excessive force, allowing the copper wire 1 to slide relative to the rotating cover plate 701. In this way, the copper wire 1 will be continuously subjected to a uniform and stable reaction force from the rotating cover plate during the continuous sliding process. This makes the copper wire unwinding speed stable and the tension uniform, and the quality of subsequent processing is also more stable and reliable.
