Description

Technical Field

[0001] The utility model relates to the field of cable processing equipment, in particular to a wire-paying device for cable processing. Background Art

[0002] Cables are typically composed of several conductors or groups of conductors. The manufacturing of wires and cables differs significantly from the production of most electromechanical products. These typically involve assembling components into subassemblies, which are then assembled into single units, with product measurement measured in units or pieces. All wires and cables begin with conductor processing, with insulation, shielding, cabling, and sheathing added layer by layer to create the finished product. Pay-off machines are used in the cable processing process as auxiliary equipment for laying out the wires, facilitating their transfer to the next process step.

[0025] The left side frame 110 and the right side frame 120 are fixedly mounted on the left and right sides of the top of the bottom plate 140, respectively. A trapezoidal rib plate 141 is provided between the left side of the left side frame 110 and the top of the bottom plate 140 to enhance the connection strength between the left side frame 110 and the bottom plate 140. Similarly, a trapezoidal rib plate 141 is provided between the right side of the right side frame 120 and the top of the bottom plate 140 to enhance the connection strength between the right side frame 120 and the bottom plate 140.

[0026] The pay-off power mechanism 2 includes a pay-off shaft 201 and a pay-off motor 202 for driving the pay-off shaft 201 to rotate. The pay-off shaft 201 is rotatably arranged on the left side frame 110 through a bearing and a bearing seat, and the pay-off motor 202 is fixedly installed on the left side of the left side frame 110. At the same time, the output shaft of the pay-off motor 202 is connected to the pay-off shaft 201 in a transmission manner; a retaining ring 203 is also integrally formed on the side of the pay-off shaft 201 close to the left side frame 110; the pay-off motor 202 is a motor with a reducer;

[0027] like Figure 6The docking mechanism 3 includes a movable sleeve 301, a fixed sleeve 302 and a docking cylinder 303, wherein the fixed sleeve 302 is fixedly mounted on the right side frame 120, the movable sleeve 301 is slidably arranged in the fixed sleeve 302, and the docking cylinder 303 is fixedly mounted on the right side of the right side frame 120. The output shaft of the docking cylinder 303 passes through the right side frame 120 and is fixedly connected to a connecting plate 304. The bottom of the connecting plate 304 is fixedly connected to the top of the movable sleeve 301. It is worth noting that the diameter of the inner cavity of the movable sleeve 301 is larger than the outer diameter of the pay-off shaft 201.

[0028] When the utility model is used, the pay-off drum 9 is loaded from the right side of the pay-off shaft 201, and then the docking cylinder 303 of the docking mechanism 3 drives the movable sleeve 301 to move to the left, the pay-off shaft 201 is inserted into the movable sleeve 301, and then the movable sleeve pushes the pay-off drum 9 to the left, and the left side of the pay-off drum 9 abuts against the retaining ring 203, that is, the installation of the pay-off drum is completed; then the pay-off motor 202 drives the pay-off drum 9 to rotate;

[0029] The outlet mechanism 5 includes at least one guide wheel 501 and one guide roller 502.

[0030] The guide wheel 501 is fixedly mounted on a guide wheel shaft 503, which is rotatably connected to a guide bearing seat 504 via a bearing. The guide bearing seat 504 is fixedly mounted on the front top of the rear side frame 130. The guide roller 502 is located below the guide wheel 501. Both ends of the guide roller 502 are rotatably connected to a guide mounting seat 505 via bearings and a bearing seat. The guide mounting seat 505 is fixedly mounted on the front bottom of the rear side frame 130.

[0031] The cable to be processed, which is drawn from the pay-off drum 9, passes through the guide roller 502 and is then introduced into the guide wheel 501;

[0032] The existing pay-off device has a basically constant pay-off speed, mainly because the weight of the wire drum is very large and the inertia generated after rotation is also large. The method of simply changing the speed of the wire drum by changing the speed of the motor requires a certain amount of time to decelerate and accelerate, making the speed change of the wire drum more troublesome.

[0033] Therefore, the present invention adopts an online buffer mechanism 4, which can quickly change the output speed of the cable pay-off device for cable processing without immediately changing the rotation speed of the pay-off power mechanism 2; the response speed is fast;

[0034] The online caching mechanism 4 includes a fixed winding wheel 410, a movable winding wheel 420 and a lifting device 440 for driving the movable winding wheel 420 to rise and fall; the fixed winding wheel 410 is arranged at the same height as the guide wheel 501; the fixed winding wheel 410 and the movable winding wheel 420 have the same structure, and the surfaces of both are provided with wheel grooves 430 arranged at even intervals; the fixed winding wheel 410 is fixedly mounted on a fixed wheel shaft 411, and the fixed wheel shaft 411 is rotatably connected to a fixed bearing seat 412 through a bearing, and the fixed bearing seat 412 is fixedly mounted on the front end of the rear side frame 130; the movable winding wheel 420 is fixedly mounted on a movable wheel shaft 421, and the movable wheel shaft 421 is rotatably connected to a movable bearing seat 422 through a bearing, and the movable bearing seat 422 is fixedly mounted on the front end of a movable shaft seat bracket 424, and the movable bearing seat 422 is located at the front end of the rear side frame 130;

[0035] The lifting device 440 includes an optical axis 441, a ball screw 443, and a lifting motor 444 driving the ball screw 443;

[0036] There are two optical axes 441, and the two optical axes 441 are fixedly mounted on the lifting frame 445. Sliders 442 are slidably connected to the optical axes 441 via linear bearings. The front ends of the slides 442 pass through the rear side frame 130 and are fixedly connected to the rear end of the movable shaft seat bracket 424. Correspondingly, a rectangular groove 131 is formed on the rear side frame 130 corresponding to the slides 442 to facilitate the up and down movement of the slides 442.

[0037] The ball screw 443 includes a screw and a screw nut, wherein the upper and lower ends of the screw are rotatably connected to the lifting frame 445 through bearings; the lifting frame 445 is fixedly mounted on the rear side of the rear side frame 130, and the screw nut is fixedly mounted on the rear side of the slider 442 through the nut seat 4; the lifting motor 444 is fixedly mounted on the top of the lifting frame 445;

[0038] The fixed winding wheel 410 and the guide wheel 501 are arranged at the same height; the cable drawn out from the guide wheel 501 will first pass through the fixed winding wheel 410, and then the cable will be wound multiple times on the fixed winding wheel 410 and the movable winding wheel 420 before finally being drawn out from the fixed winding wheel 410;

[0039] When the present invention is in use, the lifting motor 444 drives the screw to rotate, thereby driving the screw nut to rise and fall, and then driving the movable shaft seat bracket 424 to rise and fall, that is, adjusting the distance between the movable line wheel and the fixed line wheel through the lifting device 5 to adjust the length of the cable wound on the movable line wheel and the fixed line wheel.

[0040] For example, when the processing speed of the subsequent process is reduced (that is, the pay-off speed of the cable processing pay-off device needs to be reduced); at this time, the distance between the movable wire wheel and the fixed wire wheel is increased, so that the wire remaining on the cable processing line buffer structure increases. At this time, the pay-off speed of the entire cable processing pay-off device will be immediately reduced, and the pay-off power mechanism 2 does not need to immediately slow down the wire output speed. If the subsequent pay-off speed needs to continue, it can be reduced by slowly reducing the rotation speed of the pay-off power mechanism 2.

[0041] On the contrary, when the processing speed of the subsequent process is increased, the distance between the movable reel and the fixed reel can be reduced, and the wire-paying speed of the wire-paying device for overall cable processing can be increased immediately.
