Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of winding machines, in particular to a wire feeding device and a winding machine. Background Art
[0002] The existing winding machines generally include a wire clamping device and a winding device. The wire passes through the wire feeding device and the wire clamping device and is directly wound on the winding shaft of the winding device. The wire feeding device includes a wire feeding wheel and a wire feeding tube. When the wire starts from the wire feeding wheel and is guided through the wire feeding tube, when wires of different diameters enter the wire feeding tube of the same diameter, the wire with a smaller diameter is softer in material. When it travels in the wire feeding tube over a longer distance, the wire that enters first and the wire that enters later will overlap in the wire feeding tube due to the resistance of the tube wall, resulting in the inability of the thin wire to be transferred to the winding device position and the wire feeding failure.

It should be noted that one end of the connecting block 33 is fixedly arranged with the lower clamping plate 42, and the other end is telescopically connected with the wire feeding drive unit 31, that is, the wire feeding drive unit 31 is telescopically connected with the lower clamping plate 42 through the connecting block 33; the sliding device 32 is slidably arranged under the lower clamping plate 42, and by starting the wire feeding drive unit 31, the connecting block 33 drives the lower clamping plate 42 and the upper clamping plate 41 to slide back and forth on the sliding device 32; the clamping wire driving unit 43 is connected to the upper clamping plate 41 by driving, and by starting The upper clamping plate 41 of the clamping driving part 43 moves toward the lower clamping plate 42 to clamp the wire in the wire channel 421; in this embodiment, the upper pressing head 411 is elastically arranged and can be made of plastic material, or a layer of plastic material is coated on its outer surface to prevent damage to the wire and adapt to wires of different sizes; when the wire passes from the wire channel 421 directly below the upper pressing head 411, the clamping driving part 43 is started to move the upper pressing plate downward, and at this time the upper pressing head 411 contacts and presses the wire to fix the position of the wire in the wire channel 421 , and then start the wire feeding drive unit 31 so that the wire clamping unit 4 drives the clamped wire on the sliding device 32 to move to the position of the wire fixing unit 5 to avoid wire feeding failure; the wire channel 421 of the wire clamping unit 4 is set to adapt to wires of different diameters, and the upper pressure head 411 is set to press the wire to prevent the front section of the wire and the rear section of the wire from overlapping in the wire channel 421 during the wire transfer to the wire fixing unit 5. The wire feeding device is set on the winding machine to realize the wire feeding of wires with smaller diameters on the winding machine, which is convenient and practical, and improves the wire feeding efficiency of wires of different diameters.
[0028] like Figure 5 As shown, a guiding unit 2 is provided on the workbench 1, and the guiding unit 2 is arranged on one side of the wire clamping unit 4. The guiding unit 2 includes an initial introduction member 21, a first introduction member 22, a first outlet member 23, an active feeding wheel group 24 located between the first introduction member 22 and the first outlet member 23, and a driven feeding wheel group 25 located between the first outlet member 23 and the wire clamping unit 4 and cooperating with the active feeding wheel group 24 for precise feeding.
[0029] like Figure 6As shown, a second introduction piece 44 is provided in the lower clamping plate 42, and the second introduction piece 44 is close to the driven feeding wheel group 25. A long guide block 422 extending in the wire conveying direction is provided on the end of the lower clamping plate 42 away from the second introduction piece 44, and the wire channel 421 is extended in the long guide block 422. A wire introduction hole 441 is provided in the second introduction piece 44, and a lower pressing groove 423 is provided at one end of the wire channel 421. The lowest point of the wire introduction hole 441 and the lowest point of the lower pressing groove 423 are located on the same horizontal line. The wire passing through the wire introduction hole 441 and the lower pressing groove 423 is in a suspended state in the wire channel 421, which effectively reduces the contact area between the wire and the inner wall of the wire channel 421, and reduces the resistance of the inner wall of the wire channel 421 to the wire conveying, thereby avoiding the overlap of the wire that enters first and the wire that enters later in the wire channel 421.
[0030] like Figure 4 As shown, the size of the lower pressing groove 423 is adapted to the size and the upper and lower positions of the upper pressing head 411, and a clamping groove 424 is provided above the two walls of the lower pressing groove 423, and a clamping protrusion 412 adapted to the clamping groove 424 is provided on the upper clamping plate. When the wire clamping driving part 43 is started to drive the upper clamping plate to move downward to a certain position, the upper pressing head 411 presses the wire in the lower pressing groove 423, and the clamping protrusion 412 is clamped in the clamping groove 424, limiting the position of the upper clamping plate on the lower clamping plate, preventing the upper clamping plate from moving relative to the lower clamping plate, and avoiding the wire from shifting at the position of the lower pressing groove 423.
[0031] like Figure 7 As shown, the wire fixing unit 5 includes a wire fixing frame 51, a second lead-out member 52 and a vertical plate 53. The wire fixing frame 51 is provided with a wire fixing avoidance groove 54 adapted to the long guide block 422. By starting the wire feeding drive part 31, the wire clamping unit 4 is on the sliding device 32, driving the clamped wire to move toward the position of the wire fixing unit 5. At this time, the long guide block 422 passes through and is located in the wire fixing avoidance groove 54, and the side of the long guide block 422 contacts the second lead-out member 52. Starting the wire clamping drive part 43 causes the upper clamping plate to move upward, and the upper pressure head 411 releases the wire in the lower pressure groove 423. The wire in the long guide block 422 is led out through the second lead-out member 52 for the next step of winding and cutting.
[0032] The utility model arranges that the wire only contacts the inner wall of the first introduction member 22, the inner wall of the first outlet member 23, the inner wall of the second introduction member 44, the surface of the lower pressure groove 423 and the inner wall of the second outlet member 52, which greatly reduces the resistance caused by the inner wall and can effectively avoid the overlap of the front section wire and the rear section wire in the wire channel 421 of the wire with a smaller diameter; the wire feeding device has a relatively simple structure, and the upper pressure head 411 of the upper clamping plate 41 is made of plastic material, or a layer of plastic material is coated on its outer surface. The combination of the upper clamping plate 41 and the lower clamping plate 42 can adapt to wires of different diameters and protect the wires, so that the winding machine as a whole is suitable for wires of different diameters.
