Description

Technical Field

[0001] This utility model relates to the technical field of wire processing equipment, and in particular to a wire feeding rack for wires. Background Technology

[0002] A terminal wire is an electronic connector consisting of a wire and terminals. Terminals are typically a piece of metal or a tubular structure used to attach to one or both ends of the wire, facilitating a reliable electrical connection with other circuit components. Terminal wires are widely used inside and outside various electronic devices to transmit signals, data, or power.

[0003] The terminals of existing terminal wires are generally formed by directly riveting the terminal pieces to the wire ends after the wire is fed in, stripped and cut by a terminal crimping machine, and then cold-pressed. When feeding wires, existing terminal crimping machines generally place multiple bundles of cables side by side, and then gather the wires into a row through a pulley frame and a wire bundler. After passing through a row of upper and lower pressure rollers, the wires are repeatedly bent and straightened by the upper and lower pressure rollers before entering the feeding mechanism of the processing equipment.

[0004] In actual use, the feeding mechanism has the following problems: (1) The existing wire bundler is fixed. When the wire is subjected to feeding tension, the wire in the middle area is easier to pull. However, the wires on both sides are inclined to enter. Although the opening of the wire bundle hole is rounded, the outer sheath of the wire is easily damaged when the wire is quickly pulled into the wire bundle hole. This will cause the inner core of the wire to bend and be subjected to excessive force, resulting in a certain plastic deformation. This will cause the wire to spread outwards and easily detach from the pressure roller, affecting the subsequent wire straightening process. (2) In actual work, the wire processing station needs to be changed. During the change process, the wire will partially retract, affecting the meter recorder's recording effect. (3) Since the distance between the upper and lower pressure rollers is fixed, or the pressure is provided by the upper pressure roller spring, although it does not affect the feeding and straightening effect, it is necessary to put each wire in the wire bundle sequentially when feeding. The wire feeding efficiency is low and there is room for further improvement. Utility Model Content

[0005] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a wire feeding cable tie, thereby solving the above-mentioned problem.

[0006] To achieve the above objectives, a wire feeding cable tie is provided, comprising an L-shaped connector fixed on the workbench of a wire terminal processing equipment, a support base fixedly connected above the L-shaped connector, a meter counter fixedly connected above the end of the support base away from the L-shaped connector, wiring sleeves provided on both sides above the meter counter, limit sliding pins fixedly connected on both sides of the end of the meter counter away from the support base, a cable tie slidably connected to the end of the meter counter away from the support base via the two limit sliding pins, a plurality of cable tying holes equally spaced in the middle of the cable tie, and a buffer spring movably sleeved between the two limit sliding pins and the cable tie.

[0007] Multiple guide rollers are rotatably connected to the middle of the side of the support base near the meter counter. Three fixed bases are fixedly connected at equal intervals above the support base. An inverted L-shaped slide block is fixedly connected to the middle of the side of each of the three fixed bases near the guide rollers. A lifting slider is slidably connected to the side of each of the three fixed bases near the guide rollers through the inverted L-shaped slide block. Two lifting rollers are provided on the side of each of the three lifting sliders near the guide rollers. A lifting screw is provided on the top side of each of the three inverted L-shaped slide blocks away from the fixed base. Screw holes are opened at the corresponding positions of the three lifting sliders and the lifting screw.

[0008] On the side of the support base near the guide roller, a fixed shaft is fixedly connected at the position between the meter counter and the guide roller. A pitching device is rotatably sleeved on the outside of the fixed shaft, and multiple threaded tubes are fixedly connected above the pitching device.

[0009] According to the wire feeding cable bundle frame, the ends of the two limiting slides away from the meter counter are fixedly fitted with limiting caps.

[0010] According to the wire feeding cable tie frame, the top of each of the three lifting screws passes through the top of the inverted L-shaped slide and is rotatably connected to the inverted L-shaped slide, and a handwheel is fixedly sleeved on the top of each of the three lifting screws.

[0011] According to the wire feeding cable tie frame, the lower parts of the three lifting screws pass through corresponding screw holes and are threadedly engaged with the corresponding lifting sliders through the screw holes. The bottoms of the three lifting screws are rotatably connected to the support base.

[0012] According to the wire feeding cable bundle frame, the distance between the two lifting rollers on the three lifting sliders is the same as the distance between the multiple guide rollers, the center of each of the three lifting sliders is located directly above one of the guide rollers, and the distance between the three lifting sliders is at least the distance between two guide rollers.

[0013] According to the wire feeding cable bundle frame, a roller shaft is provided through the center of each of the plurality of wire rollers and lifting rollers, and the ends of the roller shafts are respectively fixedly connected to a support base or a corresponding lifting slider.

[0014] According to the wire feeding harness described above, the support base is fixedly connected to a limiting shaft below the end of the pitcher near the guide roller.

[0015] The above solution has at least one of the following beneficial effects:

[0016] 1. This utility model is equipped with a wire harness, which works in conjunction with a limiting slide and a buffer spring. By setting a movable wire harness at the front end of the meter counter, the wire is constrained by the wire harness before entering the meter counter, which facilitates the meter counter's measurement work. Furthermore, by setting a buffer spring, when the wire is subjected to huge tensile force, the backward movement of the wire harness buffers the force, reduces the damage to the wire, and enhances the practicality of the device.

[0017] 2. This utility model, by setting a pitching device between the meter counter and the guide roller, not only uses the threading tube above the pitching device to constrain the wire on both sides before it enters the pressure roller area, but also, when the wire retracts, the up-and-down pitching motion of the pitching device allows the wire passing through the top of the pitching device to bend in the vertical direction, thus buffering the amount of wire retraction. This greatly reduces the impact of wire retraction on the meter counter and enhances the practicality of the device.

[0018] 3. Compared with the prior art, the upper pressure roller of this utility model is a lifting roller that can be raised and lowered. It can not only adjust the bending degree of the wire, but also separate the staggered upper and lower pressure rollers when feeding new materials, so as to facilitate the one-time feeding of the wire bar and improve the feeding efficiency of the wire bar.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0027] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0028] Reference Figure 1-4 This utility model provides a wire feeding cable bundler, including an L-shaped connector 1 fixed on the workbench of a wire terminal processing equipment. A support base 2 is fixedly connected above the L-shaped connector 1. A meter counter 3 is fixedly connected above the end of the support base 2 away from the L-shaped connector 1. Wiring sleeves 4 are provided on both sides above the meter counter 3. Limiting sliding posts 5 are fixedly connected to both sides of the end of the meter counter 3 away from the support base 2. A cable bundler 6 is slidably connected to the end of the meter counter 3 away from the support base 2 via the two limiting sliding posts 5. Each end of the meter counter 3 is fixedly fitted with a limit cap. The middle of the wire bundler 6 is provided with multiple wire bundle holes 7 at equal intervals. Two limit sliding pins 5 are movably fitted with buffer springs 16 between the wire bundler 6 and the meter counter 3. By setting a movable wire bundler 6 at the front end of the meter counter 3, multiple wires can be constrained into a row by the wire bundler 6 before entering the meter counter 3, which facilitates the meter counter 3 to perform measurement work. Moreover, by setting buffer springs 16, when the wires are subjected to huge tensile force, the backward movement of the wire bundler 6 buffers the pulling force and reduces the damage to the wires.

[0029] Multiple guide rollers 8 are rotatably connected to the center of the support base 2 near the meter counter 3. Three fixed bases 9 are equidistantly fixed above the support base 2. Each of the three fixed bases 9 has an inverted L-shaped slide block 10 fixedly connected to its center near the guide rollers 8. Each of the three fixed bases 9 has a lifting slider 11 slidably connected to its center near the guide rollers 8 via the inverted L-shaped slide block 10. Each of the three lifting sliders 11 has two lifting rollers 12 on its center near the guide rollers 8. A roller shaft passes through the center of each of the multiple guide rollers 8 and the lifting rollers 12, and the ends of the roller shafts are fixedly connected to the support base 2 or the corresponding lifting slider 11. The distance between the two lifting rollers 12 on each of the three lifting sliders 11 is the same as the distance between the multiple guide rollers 8. The center of each of the three lifting sliders 11 is positioned directly above one of the guide rollers 8. The distance between each of the three lifting sliders 11 is at least the distance between two guide rollers 8. A lifting slider is provided on the top of each of the three inverted L-shaped slide blocks 10 away from the fixed base 9. The three lifting screws 13 pass through the top of the inverted L-shaped slide block 10 and are rotatably connected to it. The top of each of the three lifting screws 13 is fixedly fitted with a handwheel 15. Each of the three lifting sliders 11 has a screw hole 14 at a position corresponding to the lifting screw 13. The bottom of each of the three lifting screws 13 passes through the corresponding screw hole 14 and is threadedly engaged with the corresponding lifting slider 11 through the screw hole 14. The bottom of each of the three lifting screws 13 is rotatably connected to the support base 2. By rotating the handwheel 15, the corresponding lifting slider 11 can be raised or lowered by rotating the lifting screw 13, which facilitates the height adjustment of the corresponding lifting roller 12. By converting the upper pressure roller into a liftable lifting roller 12, not only can the bending degree of the wire be adjusted, but also when feeding new material, the lifting roller 12 can be raised to separate the staggered upper and lower pressure rollers, which facilitates the one-time insertion of the wire bar and improves the feeding efficiency of the wire bar.

[0030] A fixed shaft 17 is fixedly connected to the side of the support base 2 near the guide roller 8 at the position between the meter counter 3 and the guide roller 8. A pitching device 18 is rotatably sleeved on the outside of the fixed shaft 17. A limit shaft is fixedly connected to the lower end of the pitching device 18 near the guide roller 8. Multiple wire tubes 19 corresponding to the wire hole 7 are fixedly connected above the pitching device 18. Since the pitching device 18 is lighter at one end and heavier at the other, when the wire harness tends to bend, the rotation of the pitching device 18 can guide the bending direction of the wire harness to bend upward and downward instead of bending left and right, reducing the tendency of the wire harness to spread out to both sides. When the wire retracts, the up and down pitching action of the pitching device 18 can be used to allow the wire passing through the top of the pitching device 18 to bend in the up and down direction, buffering the amount of wire retraction, greatly reducing the impact of wire retraction on the meter counter 3.

[0031] Working principle: In operation, this invention uses a movable wire catcher 6 at the front end of the meter counter 3 to constrain the wire before it enters the meter counter 3, facilitating measurement. A buffer spring 16 is also installed to cushion the pulling force when the wire is subjected to high tension, reducing damage to the wire. Furthermore, a tilting device 18 is installed between the meter counter 3 and the guide roller 8. This not only allows for lateral constraint of the wire by the threading tube 19 above the tilting device 18 before it enters the pressure roller area, but also, when the wire retracts, the tilting motion of the tilting device 18 allows the wire passing above it to bend vertically, buffering the amount of retraction and significantly reducing the impact of wire retraction on the meter counter 3.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
