Description

Technical Field

[0001] This utility model relates to the field of wire feeding frame technology, and more specifically, to a wire structure for a wire feeding frame. Background Technology

[0002] A wire feeding frame is a device used to feed wire. During use, the wire is wound onto a feed reel located on the frame. When the end of the wire is pulled, it is pulled off the reel. To meet the directional requirements of wire feeding, wire feeding frames currently on the market also have a guide structure. This guide structure guides the wire to change its feeding direction. The guide structure currently on the wire feeding frame mainly includes a guide sleeve, which is fixed to the frame. However, the wire on the feed reel is wound along the axial direction of the reel. Because the guide sleeve is fixed to the frame, its orientation cannot be flexibly adjusted according to the wire's position. Therefore, during the feeding process, as the wire gradually shifts from the center of the reel's axial direction towards both ends, the guide sleeve's guidance can easily cause the wire to bend, become crooked, or even break. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a wire structure for a wire feeding frame, which can prevent the wire from bending or breaking when guiding the wire from the wire feeding wheel, thereby improving the reliability of wire guiding.

[0004] This utility model provides a wire feeding frame structure, including a support, a wire wheel, and a guide sleeve; the support is fixed on the crossbeam of the wire feeding frame, and the wire wheel is rotatably connected to the support; the wire feeding structure also includes a connecting seat, a swing arm, and a connecting plate; the connecting seat is fixed on the crossbeam, the upper end of the swing arm is rotatably connected to the connecting seat, the connecting plate is connected to the lower end of the swing arm, a support sleeve is provided on one end of the connecting plate, and the guide sleeve is axially inserted into the support sleeve and fastened to the support sleeve; the wire fed by the wire feeding wheel on the wire feeding frame passes through the guide sleeve and is guided by the wire wheel before being fed out from the wire feeding frame.

[0005] By adopting the above structure, when the guide sleeve guides the wire from the pay-off reel, the rotation of the swing arm and the connecting seat allows the position of the guide sleeve relative to the crossbeam to be adjusted according to the position of the wire. In other words, when the guide sleeve guides the wire, it can prevent the wire from bending or even breaking, thus improving the reliability of wire guidance.

[0006] In one possible implementation, an adjustment structure is provided between the connecting plate and the lower end of the swing arm. The adjustment structure is used to adjust the distance between the support sleeve and the swing arm. By providing the adjustment structure between the connecting plate and the lower end of the swing arm, the adjustment structure adjusts the distance between the support sleeve and the swing arm, thereby adjusting the distance between the guide sleeve and the swing arm to a suitable state so that the guide sleeve can smoothly guide the wire.

[0007] In one possible implementation, the adjustment structure includes a bolt. The upper end of the connecting plate is provided with a groove extending radially along the support sleeve. The bottom of the groove is provided with an elongated hole extending radially along the support sleeve. The lower end of the swing arm is inserted into the groove and slidably connected to it. The lower end of the swing arm is provided with a first threaded hole. The threaded portion of the bolt passes through the elongated hole and is threadedly connected to the first threaded hole. The connecting plate is fastened to the lower end of the swing arm by the bolt. With this adjustment structure, when the bolt is loosened, the connecting plate can slide relative to the lower end of the swing arm. That is, at this time, the lower end of the swing arm can slide along the length of the groove, and the threaded portion of the bolt can slide in the elongated hole. When the relative position of the guide sleeve and the swing arm is adjusted to a suitable state, the bolt is tightened again to fasten the connecting plate to the lower end of the swing arm.

[0008] In one possible implementation, the lower end of the swing arm is provided with two flat surfaces on both the front and rear sides. The two flat surfaces abut against and slide against the two inner sidewalls of the slide groove, respectively. By adopting this structure, the circumferential limit of the connecting plate and the swing arm can be achieved by the two flat surfaces abutting against the two inner sidewalls of the slide groove, so as to avoid the connecting plate from rotating relative to the swing arm in the circumferential direction, thereby improving the reliability of the connecting plate and the swing arm after fastening.

[0009] In one possible implementation, the outer wall of the guide sleeve is provided with a plurality of annular grooves spaced apart along the axial direction of the guide sleeve, and the side wall of the support sleeve is provided with a second threaded hole corresponding to each annular groove. Each second threaded hole is threaded with a screw, and the inner end of each screw is inserted into the annular groove at the corresponding position and abuts against the side wall of the annular groove. With this structure, the guide sleeve and the support sleeve can be fastened after the screw abuts against the side wall of the annular groove. Since the inner end of the screw is inserted into the annular groove, the axial separation of the guide sleeve from the support sleeve can be avoided, thereby improving the reliability and firmness of the fastening of the guide sleeve and the support sleeve. When the screw is loosened so that the inner end of the screw comes out of the annular groove, the guide sleeve can be removed from the support sleeve to replace the guide sleeve.

[0010] In one possible implementation, the connecting seat is provided with an opening slot, and the upper end of the swing arm is inserted into the opening slot and rotatably connected to the connecting seat via a rotating shaft; by adopting this structure, the upper end of the swing arm can be reliably rotatably connected to the connecting seat via the rotating shaft.

[0011] In one possible implementation, the connector is welded to or fixed to the crossbeam by a number of screws; with this structure, the connector can be reliably fixed to the crossbeam. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] See Figure 1-5 As shown in the embodiment of this application, a wire feeding frame structure is disclosed, including a support 1, a wire wheel 2, and a guide sleeve 3. The support 1 is fixed on the crossbeam 4 of the wire feeding frame, and the wire wheel 2 is rotatably connected to the support 1. The wire feeding structure also includes a connecting seat 5, a swing arm 6, and a connecting plate 7. The connecting seat 5 is fixed on the crossbeam 4, the upper end of the swing arm 6 is rotatably connected to the connecting seat 5, the connecting plate 7 is connected to the lower end of the swing arm 6, a support sleeve 71 is provided on one end of the connecting plate 7, and the guide sleeve 3 is axially inserted into the support sleeve 71 and fastened to the support sleeve 71. The wire fed by the wire feeding wheel on the wire feeding frame passes through the guide sleeve 3 and is guided by the wire wheel 2 before being fed out from the wire feeding frame.

[0022] An adjustment structure is provided between the lower end of the connecting plate 7 and the swing arm 6. The adjustment structure is used to adjust the distance between the support sleeve 71 and the swing arm 6. After the adjustment structure is provided between the lower end of the connecting plate and the swing arm, the adjustment structure adjusts the distance between the support sleeve and the swing arm, so that the distance between the guide sleeve and the swing arm can be adjusted to a suitable state, so that the guide sleeve can smoothly guide the wire.

[0023] The adjustment structure includes a bolt 8. The upper end of the connecting plate 7 is provided with a groove 72 extending radially along the support sleeve 71. The bottom of the groove 72 is provided with an elongated hole 73 extending radially along the support sleeve 71. The lower end of the swing arm 6 is inserted into the groove 72 and slidably connected to the groove 72. The lower end of the swing arm 6 is provided with a first threaded hole 61. The threaded part of the bolt 8 passes through the elongated hole 73 and is threadedly connected to the first threaded hole 61. The connecting plate 7 is fastened to the lower end of the swing arm 6 by the bolt 8. With this adjustment structure, when the bolt is loosened, the connecting plate can slide relative to the lower end of the swing arm. That is, at this time, the lower end of the swing arm can slide along the length of the groove, and the threaded part of the bolt can slide in the elongated hole. When the relative position of the guide sleeve and the swing arm is adjusted to a suitable state, the bolt is tightened again to fasten the connecting plate to the lower end of the swing arm.

[0024] The lower end of the swing arm 6 has two flat surfaces 62 on both the front and rear sides. The two flat surfaces 62 abut against and slide against the two inner sidewalls of the slide groove 72 respectively. By adopting this structure, the two flat surfaces abut against the two inner sidewalls of the slide groove, which can achieve circumferential limitation of the connecting plate and the swing arm, so as to avoid the connecting plate from rotating relative to the swing arm in the circumferential direction, thus improving the reliability of the connecting plate and the swing arm after fastening.

[0025] The outer wall of the guide sleeve 3 is provided with several annular grooves 31 spaced apart along the axial direction of the guide sleeve 3. The side wall of the support sleeve 71 is provided with second threaded holes 74 corresponding to the annular grooves 31 one by one. Each second threaded hole 74 is threaded with a screw 9. The inner end of each screw 9 is inserted into the annular groove 31 at the corresponding position and abuts against the side wall of the annular groove 31. With this structure, the guide sleeve and the support sleeve can be fastened after the screw abuts against the side wall of the annular groove. Since the inner end of the screw is inserted into the annular groove, the axial separation of the guide sleeve from the support sleeve can be avoided, which can improve the reliability and firmness of the guide sleeve and the support sleeve after fastening. When the screw is loosened so that the inner end of the screw comes out of the annular groove, the guide sleeve can be removed from the support sleeve to replace the guide sleeve.

[0026] The connecting seat 5 is provided with an opening slot 51, and the upper end of the swing arm 6 is inserted into the opening slot 51 and rotatably connected to the connecting seat 5 through the rotating shaft 63. With this structure, the upper end of the swing arm can be reliably rotatably connected to the connecting seat through the rotating shaft.

[0027] The connecting seat 5 is welded or fixed to the crossbeam 4 by several screws; with this structure, the connecting seat can be reliably fixed to the crossbeam.

[0028] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
