Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wire feeding devices, and specifically relates to a wire feeding device for processing enameled wire. Background Technology
[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked. Based on the shape of the material, enameled wire can be classified into flat wire, round wire, and hollow wire.
[0003] Currently, in the production process of enameled wire, the wire feeding device generally includes a wire feeding frame and a guide roller. The wire roll is installed on the wire feeding frame. During wire feeding, the wire gradually unwinds from the wire roll and passes through the guide roller to be continuously transported to the subsequent work station.
[0004] However, in actual production, since the wire is tightly wound on the roller, the outer diameter of the coil and the unwinding position of the wire are constantly changing as the roller rotates. This causes the angle between the wire and the guide wheel to change continuously, which increases the probability of wear between the wire and the guide wheel and affects the quality of the final enameled wire product. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a brand-new wire feeding device for enameled wire processing.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A wire feeding device for enameled wire processing includes a wire feeding frame with an unwinding station, a guide roller, and a roller with wire wound on it placed at the unwinding station. The wire is unwound from the roller and forms an unwinding section between the roller and the guide roller. The wire feeding frame includes a base frame and a movable frame movably connected to the base frame to form the unwinding station. The wire feeding device also includes a power unit, which includes a guide rail extending along the axial direction of the roller, a first power unit, and a second power unit. The base frame is slidably connected to the guide rail. During unwinding, the first power unit drives the base frame to reciprocate along the axial direction of the roller, and the second power unit drives the movable frame and synchronously adjusts the unwinding station up and down. The projection position of the unwinding section remains unchanged in the horizontal and vertical planes.
[0008] Preferably, in the orthographic projection onto the horizontal plane, the unwinding section is perpendicular to the centerline of the guide wheel. Here, the friction between the unwinding section and the guide wheel is minimized.
[0009] Preferably, in the orthographic projection on the vertical plane, the tilt angle of the unwinding section relative to the horizontal plane remains unchanged, and the tilt angle is 20° to 30°.
[0010] Preferably, the movable frame is pivotally connected to the base frame, and the unwinding station is formed at one end of the movable frame, and the second power device drives the movable frame to rotate up and down about the center line of the pivot.
[0011] Specifically, during unwinding, the end of the movable frame, at which the unwinding station is formed, is rotated up from bottom to top. In this way, as the outer diameter of the wire coil gradually decreases, the height of the unwinding station is adjusted from bottom to top, so that the height of the lower end of the unwinding section is kept unchanged, and thus the inclination angle of the unwinding section relative to the horizontal plane is kept unchanged.
[0012] Preferably, the movable frame is pivotally connected to the base frame from the middle of the opposite sides, and the second power device comprises a telescopic power rod, which is pivotally connected between the end of the movable frame, away from the unwinding station, and the end of the base frame, away from the unwinding station.
[0013] Preferably, the first power device comprises a power screw arranged on the base frame and extending along the axial direction of the roller, and a fixed frame fixed to the ground and having a connecting sleeve threadedly matched with the power screw, the connecting sleeve being sleeved on the power screw, and under the rotation of the power screw, the base frame reciprocally slides along the guide rail, and the movement speed of the base frame is the same as the change speed of the unwinding position of the wire in the axial direction of the roller. In this way, the base frame has high movement precision, and the movement of the base frame is accurately matched with the unwinding of the wire.
[0014] Preferably, the middle part of the base frame and the movable frame is hollow, and the guide wheel is sequentially arranged from top to bottom through the movable frame and the base frame by the support and fixed to the ground. In this way, the length of the unwinding section is shortened, and the probability of swinging of the unwinding section during unwinding is reduced.
[0015] Preferably, the unwinding station comprises a first chuck and a second chuck arranged at intervals along the axial direction of the roller, and the first chuck and the second chuck are respectively formed with an insertion part capable of being inserted into the two ends of the roller on the inner wall.
[0016] Specifically, the first chuck and / or the second chuck can be arranged in an extendible and retractable manner along the axial direction of the roller. In this way, the unwinding of the wire with different specifications is flexibly applicable.
[0017] Compared with the prior art, the present application has the following advantages due to the implementation of the above technical solutions:
[0018] The existing wire is tightly arranged and wound on the roller, and as the roller rotates, the outer diameter of the material roll and the unwinding position of the wire are constantly changing, thereby causing the angle between the wire and the wire guide wheel to constantly change, thereby increasing the probability of wear between the wire and the wire guide wheel, and affecting the quality of the final enameled wire product; and the structure of the wire unwinding device for enameled wire processing is designed as a whole, and the deficiencies and defects of the prior art are ingeniously solved, and after the wire unwinding device is adopted, the roller wound with the wire is installed on the unwinding station, and as the roller rotates, the wire is unwound from the roller and forms an unwinding section located between the roller and the wire guide wheel, wherein as the unwinding position of the wire from the roller changes, the chassis is driven to reciprocate along the axial direction of the roller by the first power device, and as the outer diameter of the wire roll on the roller changes, the movable frame is driven by the second power device and drives the unwinding station to be adjusted up and down synchronously, and the projection position of the unwinding section on the horizontal plane and the vertical plane remains unchanged. Therefore, compared with the prior art, on the one hand, through the cooperation of the first and second power devices, the unwinding height and unwinding position of the wire are adjusted in real time to ensure that the horizontal and vertical positions of the wire remain unchanged, thereby ensuring that the angle of the wire passing through the wire guide wheel is constant, greatly reducing the probability of wear and effectively improving the quality of the product; on the other hand, the structure is simple, reliable and easy to operate.

[0029] As shown in Figures 1 to 3 The unwinding device for enameled wire processing of the embodiment includes a winding rack 1 formed with an unwinding station w, a guide wheel 2, and a power unit 3. The drum T wound with wire is placed in the unwinding station w extending along the left-right direction, and the wire is unwound from the drum T and forms an unwinding section D between the drum and the guide wheel.
[0030] Specifically, the winding rack 1 includes a base frame 10, a movable frame 11 movably connected to the base frame 10 and forming the unwinding station w. The movable frame 11 is connected to the base frame 10 through a pivot s, and the unwinding station w is formed at one end of the movable frame 11. The movable frame 11 is rotatably connected to the base frame 10 from the middle of the opposite sides.
[0031] At the same time, the unwinding station w includes a first chuck w1 and a second chuck w2 arranged along the axial direction of the drum. The first chuck w1 and the second chuck w2 are respectively formed with an insertion part b capable of being inserted into both ends of the drum on the inner wall. The first chuck w1 and / or the second chuck w2 can be arranged in an axial telescopic manner, and the telescopic manner can be motorized or manual. Here, it is flexible to apply to different specifications of wire unwinding.
[0032] In order to facilitate implementation, the middle part of the base frame 10 and the movable frame 11 is hollow, and the guide wheel 2 passes through the movable frame 11 and the base frame 10 from top to bottom in turn through the support 20 and is fixed on the ground. Here, it is convenient to shorten the length of the unwinding section and reduce the probability of unwinding section swing in unwinding.
[0033] In the example, the power unit 3 comprises a guide rail 30 extending along the axial direction of the roller T, a first power device 31 and a second power device 32, wherein the chassis 10 is slidingly connected to the guide rail 30, the first power device 31 drives the chassis 10 to reciprocate along the axial direction of the roller T during unwinding, and the second power device 32 drives the movable frame 11 and the unwinding station w to be synchronously adjusted up and down, so that the projection position of the unwinding section D on the horizontal plane and the vertical plane remains unchanged; in the orthographic projection on the horizontal plane, the unwinding section D is perpendicular to the center line of the wire guide wheel 2. At this time, the friction between the unwinding section and the wire guide wheel is minimized. Meanwhile, in the orthographic projection on the vertical plane, the inclination angle of the unwinding section D relative to the horizontal plane remains unchanged, and the inclination angle is 20°-30°.
[0034] In some specific embodiments, the first power device 31 comprises a power screw 310 arranged on the chassis 10 and extending along the axial direction of the roller, a fixed frame 311 fixed to the ground and having a connecting sleeve t threadedly matched with the power screw 310, the connecting sleeve t is sleeved on the power screw 310, and under the rotation of the power screw 310, the chassis 10 reciprocates along the guide rail 30, and the movement speed of the chassis 10 is the same as the change speed of the unwinding position of the wire on the roller in the axial direction. At this time, the chassis has high movement precision, and the movement of the chassis is accurately matched with the unwinding of the wire.
[0035] In addition, the second power device 32 drives the movable frame 11 to be arranged to be flipped up and down around the center line of the pivot s; during unwinding, the end portion of the movable frame 11, on which the unwinding station w is formed, is flipped up from bottom to top. At this time, as the outer diameter of the wire coil gradually decreases, the height of the unwinding station is adjusted from bottom to top, so that the height of the lower end of the unwinding section remains unchanged, and the inclination angle of the unwinding section relative to the horizontal plane is ensured to remain unchanged. The second power device 32 comprises a telescopic power rod 320, which is rotatably connected between the end portions of the movable frame 11 and the chassis 10 away from the unwinding station w.
[0036] In summary, after the wire unwinding device is adopted, the roller wound with the wire is installed on the unwinding station, and during unwinding, the wire is unwound from the roller and forms an unwinding section between the roller and the wire guide wheel, wherein as the unwinding position of the wire on the roller changes, the chassis is driven by the first power device to reciprocate along the axial direction of the roller, and as the outer diameter of the wire coil on the roller changes, the movable frame is driven by the second power device and the unwinding station is synchronously adjusted up and down, so that the projection position of the unwinding section on the horizontal plane and the vertical plane remains unchanged. Therefore, compared with the prior art, on the one hand, the unwinding height and the unwinding position of the wire are adjusted in real time through the cooperation of the first and second power devices, so that the horizontal and vertical positions of the wire remain unchanged, the angle of the wire passing through the wire guide wheel is constant, the probability of wear is greatly reduced, and the quality of the product is effectively improved; on the other hand, the structure is simple and reliable, and the operation is convenient.
