Description

Technical Field

[0001] This utility model belongs to the field of wire conveying technology, specifically a wire feeding device. Background Technology

[0002] In automated production fields such as metal wire processing, welding, and wire forming, a continuous and stable supply of wire to processing equipment is a key prerequisite for ensuring product quality and production efficiency. The stability of the wire feeding device directly affects the processing accuracy, surface quality, and continuity of the production process; therefore, its performance is of paramount importance.

[0003] Currently, the most common feeding method is to directly unload the coiled wire onto a rotating shaft. Specifically, the operator places the entire coil of wire horizontally on a rotating frame consisting of a main shaft and a support, with one end of the wire guided towards the processing equipment via a guide wheel. During feeding, the processing equipment primarily relies on its traction force to drag the wire, thereby causing the entire rotating frame to rotate passively and gradually release the wire.

[0004] However, this traditional feeding method has significant drawbacks. First, as feeding progresses, the inner diameter of the wire coil continuously increases, leading to a growing gap between it and the main shaft of the rotating frame. This causes the wire coil to shake and bounce violently during rotation, severely disrupting the stability and tension balance of the feeding process. Second, this structure is difficult to adapt to wire coils with different inner diameters, lacking flexibility. Utility Model Content

[0007] As a further technical solution of this utility model, the bearing member includes an annular tray with a strip-shaped through groove, a rotating ring, and an internal gear ring. The rotating ring is coaxially installed at the bottom of the annular tray and passes through the top of the box and is rotatably connected to it. The internal gear ring is installed on the inner side wall of the rotating ring near the bottom end. The strip-shaped through groove is disposed through the bottom of the annular tray and corresponds to the position of the limiting member.

[0008] As a further technical solution of this utility model, the limiting component includes an elbow rod, a limiting rod, an upper slider, and a lower slider. The limiting rod is vertically inserted through the strip groove and is slidably disposed with the strip groove. The elbow rod is connected to the top of the limiting rod. The upper slider and the lower slider are both fitted onto the limiting rod. The upper slider is slidably connected to the bottom upper surface of the annular tray, and the lower slider is slidably connected to the bottom lower surface of the annular tray.

[0009] As a further technical solution of this utility model, the elastic abutment mechanism includes a slide rod, a spring, a boss, a pressure block, a movable block, and a connecting rod. The boss is installed at the center of the bearing member. The slide rod slides through the boss and the bearing member and extends into the housing to connect with the movable block. The pressure block is located at the top of the slide rod. The spring is disposed between the pressure block and the boss and is sleeved on the slide rod. Multiple connecting rods are hinged along the circumference of the movable block, and the end of the connecting rod away from the movable block is hinged to the bottom of the limiting member.

[0010] As a further technical solution of this utility model, the support frame includes a crossbeam and a guide rod.

[0011] As a further technical solution of this utility model, the lifting component includes a guide block and a locking bolt.

[0013] As a further technical solution of this utility model, the top of the box is provided with an annular opening for the rotating ring to pass through, and a bearing is installed between the rotating ring and the annular opening.

In this utility model, by setting circumferentially distributed limiting members and their matching elastic abutment mechanism, after the coiled wire is placed, multiple limiting members can automatically extend outward under the action of elastic force and tightly abut against the inner wall of the wire reel. As feeding proceeds and the inner diameter of the wire reel increases, the elastic abutment mechanism can continuously push the limiting members to adaptively follow, always maintaining effective constraint on the inner circle of the wire reel, thereby significantly reducing the radial and axial sway of the wire reel during rotation, fundamentally solving the problem of unstable feeding caused by changes in inner diameter.

[0017] 2. In this utility model, by rotatably connecting the carrier to the top of the box and setting a drive unit inside the box to directly drive the carrier to rotate actively, an active and controllable feeding mode is achieved. This structure replaces the traditional passive feeding method that relies on equipment traction, effectively avoiding the problem of wire breakage or loosening and tangling caused by excessive inertia of the rotating frame, ensuring the stability of the feeding tension, and providing a second layer of protection for the stability of feeding.

[0018] 3. In this utility model, by circumferentially arranging multiple support frames with wire threading components on the outer side wall of the housing, multiple uniform and reliable guiding support points are provided for the wire drawn from the wire reel. This layout can guide the wire into subsequent equipment along a better path, reducing wire swaying and friction. Combined with the aforementioned anti-sway and active feeding technologies, it constitutes a complete high-stability feeding solution. Attached Figure Description

Detailed Implementation

[0021] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0022] like Figures 1-6 As shown, a wire feeding device includes a carrier 100 for placing coiled wire, a housing 200 below the carrier 100, and the carrier 100 is rotatably connected to the top of the housing 200. A drive unit 300 for driving the carrier 100 to rotate is installed inside the housing 200. Multiple circumferentially distributed limiting members 400 are vertically installed on the carrier 100. An elastic abutment mechanism 500 is installed between the limiting members 400 and the carrier 100. The elastic abutment mechanism 500 is used to drive the limiting members 400 to adaptively abut against the inner circle of the coiled wire. Multiple support frames 600 are circumferentially arranged on the outer side wall of the housing 200. A wire threading member 700 for the wire to pass through is provided on the support frame 600.

[0023] It should be noted that during use, the coiled wire is first placed on the limiting member 400. Under the action of gravity, multiple limiting members 400 are squeezed towards the axis of the bearing member 100 until the coiled wire is supported by the bearing member 100. The elastic contact mechanism 500 automatically pushes multiple circumferentially distributed limiting members 400 to move outward synchronously, so that they tightly abut against the inner circle of the coiled wire from the radial direction, achieving automatic centering and stable support. Then, the wire is pulled to pass through the threading members 700 on multiple support frames 600 in sequence and is guided to the processing equipment. Finally, the drive unit 300 is started to make the bearing member 100 drive the placed coiled wire to rotate. The rotation direction must be consistent with the discharge direction of the coiled wire. The discharge will cause the inner diameter of the coiled wire to gradually increase. The elastic contact mechanism 500 can adaptively adjust the position of the limiting member 400 so that it always abuts against the inner circle of the coiled wire, thereby ensuring the stability of the feeding.

[0024] like Figures 2-3As shown, the carrier 100 includes an annular tray 102 with a strip-shaped through groove 101, a swivel ring 103, and an internal gear ring 104. The swivel ring 103 is coaxially mounted on the bottom of the annular tray 102 and passes through the top of the box 200 and is rotatably connected to it. The internal gear ring 104 is mounted on the inner side wall of the swivel ring 103 near the bottom end. The strip-shaped through groove 101 is disposed through the bottom of the annular tray 102 and corresponds to the position of the limiting member 400.

[0025] It should be noted that the drive unit 300 meshes with the internal gear ring 104 installed on the inner sidewall of the rotating ring 103 via the gear 302, driving the rotating ring 103 to drive the coaxially fixed annular tray 102 to rotate smoothly on the top of the housing 200, achieving stable and efficient power transmission; the radially opened strip groove 101 at the bottom of the annular tray 102 provides a precise guide path for the radial movement of the limiting member 400, ensuring that the limiting member 400 can slide smoothly along the strip groove 101 under the drive of the elastic abutment mechanism 500, thereby accurately and continuously applying the adaptive clamping force to the inner ring of the wire reel; this integrated structure not only ensures the rigidity and concentricity of the bearing member 100 when rotating, but also, through the cooperation of the internal gear ring 104 transmission and the strip groove 101 guidance, makes the entire feeding device run more smoothly and clamp more reliably, effectively improving the feeding accuracy and stability.

[0026] like Figures 2-4 As shown, the limiting member 400 includes an elbow rod 401, a limiting rod 402, an upper slider 403, and a lower slider 404. The limiting rod 402 is vertically inserted through the strip groove 101 and is slidably disposed with the strip groove 101. The elbow rod 401 is connected to the top of the limiting rod 402. The upper slider 403 and the lower slider 404 are both fitted onto the limiting rod 402. The upper slider 403 is slidably connected to the bottom upper surface of the annular tray 102, and the lower slider 404 is slidably connected to the bottom lower surface of the annular tray 102.

[0027] It should be noted that when the coiled wire is placed on the limiting member 400, pressure is first applied to the elbow rod 401, thereby generating a sliding thrust on the limiting member 400 as a whole. The limiting rod 402 can adaptively abut against the inner circle of the coiled wire under the reverse force of the elastic abutment mechanism 500, thereby ensuring the stability of feeding. The slider 403 and the lower slider 404 can conveniently limit the limiting rod 402, so that it can only move along the direction of the strip groove 101.

[0028] like Figure 2 and Figure 5As shown, the elastic abutment mechanism 500 includes a slide rod 501, a spring 502, a boss 503, a pressure block 504, a movable block 505, and a connecting rod 506. The boss 503 is installed at the center of the support member 100. The slide rod 501 slides through the boss 503 and the support member 100 and extends into the housing 200 to connect with the movable block 505. The pressure block 504 is located at the top of the slide rod 501. The spring 502 is disposed between the pressure block 504 and the boss 503, and the spring 502 is sleeved on the slide rod 501. Multiple connecting rods 506 are hingedly distributed around the movable block 505, and the end of the connecting rod 506 away from the movable block 505 is hinged to the bottom of the limiting member 400.

[0029] It should be noted that when the coiled wire is placed on the limiting member 400, it will move towards the axis of the bearing member 100 under the action of gravity. During this process, the hinged connecting rod 506 will exert downward pressure on the movable block 505, so that the slide rod 501 slides down along the boss 503, thereby driving the pressure block 504 to compress the spring 502. When the coiled wire is placed on the bearing member 100, the spring 502 will drive the slide rod 501 to rise adaptively, which, together with the connecting rod 506, will cause the limiting rod 402 to adaptively abut against the inner coil of the coiled wire.

[0030] like Figure 1 and Figure 6 As shown, the support frame 600 includes a crossbeam 601 and a guide rod 602. One end of the crossbeam 601 is installed on the outer side wall of the housing 200. The guide rod 602 is vertically installed on the upper surface of the end of the crossbeam 601 away from the housing 200. A lifting component 800 is slidably arranged on the guide rod 602, and a wire threading component 700 is installed on the lifting component 800.

[0031] It should be noted that adjusting the position of the lifting component 800 on the guide rod 602 allows for height adjustment of the wire threading component 700, facilitating adaptive adjustment based on the specific feeding conditions of the wire.

[0032] like Figure 1 and Figure 6 As shown, the lifting component 800 includes a guide block 801 and a locking bolt 802. A guide hole is provided through the guide block 801, and the guide block 801 is slidably sleeved with the guide rod 602 through the guide hole. A threaded hole is provided on one side of the guide block 801, which is perpendicular to the guide hole. The locking bolt 802 is threadedly connected to the threaded hole.

[0033] It should be noted that by loosening the locking bolt 802 so that it does not contact the side wall of the guide rod 602, the guide block 801 can be pushed up and down along the guide rod 602. After adjusting to a suitable height, tighten the locking bolt 802 so that it abuts against the side wall of the guide rod 602, thereby facilitating the locking of the position of the guide block 801.

[0034] like Figure 2and Figure 6 As shown, the threading component 700 includes a vertical part 701 and a spiral part 702. The vertical part 701 is installed vertically to the lifting component 800, and the spiral part 702 is connected to the top of the vertical part 701.

[0035] It should be noted that the vertical part 701 is used to be inserted and installed with the guide block 801, and the spiral part 702 is used to easily form a conductor part for the wire to pass through, thereby guiding the wire feeding.

[0036] like Figures 2-3 As shown, the top of the housing 200 has an annular opening for the rotating ring 103 to pass through, and a bearing is installed between the rotating ring 103 and the annular opening.

[0037] It should be noted that the outer ring of the bearing is fixedly connected to the inner wall of the annular opening, and the outer wall of the swivel ring 103 is connected to the inner ring of the bearing. The bearing not only facilitates the normal rotation of the swivel ring 103, but also facilitates the positional connection between it and the housing 200.

[0038] like Figures 3-4 As shown, the elbow rod 401 gradually moves towards the axis of the annular tray 102 from the end away from the limit rod 402.

[0039] It should be noted that when ensuring the coiled wire is placed on the limiting member 400, pressure is first applied to the elbow rod 401. After being pressed, the elbow rod 401 will tend to move towards the axis of the tray 102, thereby generating a sliding thrust on the limiting member 400 as a whole.

[0040] like Figures 2-3 As shown, the drive unit 300 includes a motor 301 and a gear 302. The motor 301 is mounted on the inner side wall of the housing 200. The gear 302 is coaxially mounted with the output shaft of the motor 301 and is meshed with the internal gear ring 104.

[0041] It should be noted that when the starting motor 301 drives the gear 302 to rotate, the gear 302 can drive the internal gear ring 104 to drive the rotating ring 103 to rotate, thereby achieving stable rotation of the annular tray 102 and thus driving the coiled wire placed on the annular tray 102 to be fed stably. The above-disclosed are only a few specific embodiments of this utility model. However, the embodiments of this utility model are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
