Description

Technical Field

[0001] The utility model relates to the field of wire winding machines, in particular to a wire breaking emergency stop protection device for wire winding machines. Background Art

[0002] A wire winding machine is a mechanical device used to wind metal wire materials around a cylindrical or conical mandrel, or to directly twist and wind the wire to form a product of a certain shape and specification. According to different process principles, wire winding machines can be divided into coreless, cored continuous and cored discontinuous wire winding machines. Wire winding machines are widely used in mechanical processing, electronics and other industries, and are one of the important equipment for realizing mechanized and automated production of wire winding processes.

[0003] At present, a detection ring with an electric shock ring structure is arranged between the wire feeding frame and the wire bundle drum for stranding the wires. When a broken wire occurs, the broken wire rotates with the twisted wire bundle drum, and the free end of the broken wire is thrown outward and contacts the detection ring. The detection ring is electrically connected to the controller to turn on the protection circuit after contacting the broken wire, thereby controlling the equipment to stop and solve the wire breakage problem. However, the current detection ring is fixed in position between the rotating frame and the wire feeding frame, and the distance between the detection ring and the twisted wire in a conical bundle cannot be changed according to the degree of looseness of the twisted wire. There is a problem of the twisted wire accidentally touching the detection ring and causing the machine to stop, and the practicability is poor. Utility Model Content

[0004] The purpose of the utility model is to provide an emergency stop protection device for wire breakage at the wire bundle position of a wire winding machine in order to solve the above-mentioned problem. The detection ring serving as an electric shock ring is fixed to the top sides of two groups of sliders with adjustable spacing. The inner diameter of the detection ring is adjusted by supporting the slider to adapt to the detection of twisted wires with different distribution diameters. Details are explained below.

[0028] The detection ring 8 is a metal ring structure with an opening facing downward. The two ends of the bottom of the detection ring 8 are staggered front and back, and a controller is electrically connected between the bottom of the detection ring 8 and the cable tray 3 through a wire. The controller controls the on and off of the entire machine circuit. When the detection ring 8 contacts the broken wire conduction protection circuit, the controller controls the entire device to cut off power, thereby facilitating the detection and processing of the broken wire. A guide groove 301 is provided in the middle of the cable tray 3 to accommodate the twisted wire 4 to pass through horizontally for twisting.

[0029] As an optional implementation, a transmission gear ring 302 is coaxially fixed to one end of the cable tray 3 away from the wire feeding frame 5, a frame 201 is fixed to the side of the rotating frame 2 close to the transmission gear ring 302, a driving part 202 for driving the cable tray 3 to rotate is fixed to the outside of the frame 201, the driving part 202 is a motor with a reducer at the output end, and the output end of the driving part 202 is connected to a driving gear 203 meshing with the transmission gear ring 302, so as to ensure that the cable tray 3 can drive the multiple twisted wires 4 to be twisted into strands;

The groove 702a drives the two groups of sliders 701 to slide in the opposite direction, thereby supporting the two ends of the bottom of the detection ring 8 to move, changing the distance between the two ends of the bottom of the detection ring 8, and then changing its inner diameter, so as to change the distance between the detection ring 8 and the inner twisted wire 4, and ensure that the broken wire can contact the detection ring 8; when it is necessary to adjust the lateral position of the detection ring 8 according to the easy-to-break position of the twisted wire 4, the screw 602 is driven to rotate by rotating the handle 603, and the screw 602 is supported by the fixed frame 6 to drive the positioning block 601 to move horizontally, thereby changing the lateral position of the positioning block 601 and its top side movable frame 7 and the detection ring 8, and then the detection ring 8 is moved horizontally to the corresponding easy-to-break position of the twisted wire 4;
