Description

Technical Field

[0001] The utility model relates to the technical field of carbon brush molding machine accessories, in particular to a copper wire breakage detection device. Background Technique

[0002] In a carbon brush molding machine, raw materials such as carbon powder, metal powder (such as copper, silver, etc.) and binder are mixed evenly in a certain proportion. The mixed raw materials are put into the mold of the molding machine and pressed into the required shape and size by mechanical pressure. When pressing, the copper wire is pressed into the material and then cut. During the continuous operation of the carbon brush molding machine, the copper wire needs to be continuously conveyed. During the conveying process, it is necessary to detect in time whether the copper wire is broken. Use sensors or mechanical devices to directly contact the copper wire to detect its continuity and integrity.

[0003] In a wire breakage detection device disclosed in the existing patent publication number CN221446872U, it includes a fixing plate. A bracket is fixedly connected to the side wall of the fixing plate. A steering roller and a wire feeding roller are rotatably connected to the bracket. A wire feeding coil is sleeved on the wire feeding roller. The wire is wound around the wire feeding coil. A detection gap is provided on the fixing plate. A sliding groove is provided inside the fixing plate. A limiting slider is slidably connected inside the sliding groove. A spring is provided inside the sliding groove. The two ends of the spring are respectively fixedly connected to the inner wall of the sliding groove and the limiting slider. The lower end of the limiting slider is rotatably connected to a first rotating shaft. A first wire bundling wheel is fixedly connected to the first rotating shaft. The first wire bundling wheel matches the detection gap. A limiting groove is provided at the lower end of the detection gap. Two second rotating shafts are rotatably connected to the lower end of the detection gap. The two second rotating shafts are located on both sides of the limiting groove. A second wire bundling wheel is fixedly connected to the second rotating shaft. Both the first wire bundling wheel and the second wire bundling wheel match the wire; when there is a break in the wire, at this time the tension on the wire disappears. At this time, the first wire bundling wheel moves downward under the action of the spring. At this time, the first wire bundling wheel squeezes the wire into the limiting groove. At the same time, the air pressure inside the sliding groove decreases, and the external gas enters the sliding groove through the air inlet groove. At this time, the whistle in the air inlet groove alarms.

[0004] The above device can detect wire breakage. During the detection, the tension of the wire is used to support the first wire bundling wheel. The bottom of the wire corresponding to the first wire bundling wheel is suspended, and the wire is stressed, affecting the stable conveying of the wire. Aiming at the above problems, a copper wire breakage detection device is proposed. Content of the Utility Model

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Please refer to Figures 1 - 4 , in this embodiment, it includes a support frame 11 and two sets of wire reels 15 installed on one side of the support frame 11;

[0029] On one side of the top cross plate of the support frame 11, a mounting plate 12 is installed. A wire guide roller 19 for the copper wire to pass through is rotatably installed on the mounting plate 12. A gear 20 is installed on the wire guide roller 19. On one side of the mounting plate 12, a toggle sensor 21 for detecting the notch of the gear 20 is installed;

[0030] A positioning shaft 22 is rotatably installed on the mounting plate 12. One end of the positioning shaft 22 is fixedly connected with a pressing block 30 for limiting the copper wire passing through the wire guide roller 19. The other end of the positioning shaft 22 is installed with an adjusting rod 23. The adjusting rod 23 is rotatably connected with a spring telescopic rod 24. The end of the spring telescopic rod 24 away from the adjusting rod 23 is rotatably connected with the mounting plate 12; The spring telescopic rod 24 can be telescoped under the action of the spring to avoid pressing the copper wire too tightly by the pressing block 30;

[0031] On one side of the wire reel 15, a moving frame 16 is provided. A positioning roller 17 in contact with the copper wire coil on the wire reel 15 is installed on the moving frame 16. At the bottom of the moving frame 16, a moving member is provided for adjusting the horizontal movement of the moving frame 16;

[0032] When the device is installed and used in a carbon brush forming machine, it can be used to transport and detect copper wires. When the copper wire is transported from the wire reel 15 to the wire guide roller 19, it can drive the wire guide roller 19 to rotate, thereby driving the gear 20 to rotate. The toggle sensor 21 detects the notch and outputs a pulse signal. When the copper wire breaks, the wire guide roller 19 does not rotate, and the toggle sensor 21 cannot read it, and the signal is interrupted. The control device of the carbon brush forming machine reads the signal, which is convenient for timely stopping the machine for maintenance of copper wire transportation;

[0033] When detecting that the copper wire breaks, the wire reel 15 will output part of the copper wire. At this time, the moving frame 16 can be adjusted to be close to the wire reel 15, and at the same time, the wire reel 15 is adjusted to rotate in reverse. The positioning roller 17 contacts the outside of the copper wire coil, which can assist in storing the copper wire coil onto the wire reel 15.

[0034] As Figure 1 shown, a first fixing plate 13 is installed on one side of the support frame 11. An elbow pipe 14 for the copper wire to pass through is installed on the first fixing plate 13; The elbow pipe 14 can play a guiding role in the transportation of the copper wire.

[0035] As Figure 2 shown, second fixing plates 18 are installed at the bottom of the mounting plate 12 and on one side of the mounting plate 12 close to the wire reel 15. Wire guide cylinders for the copper wire to pass through are installed on the second fixing plates 18; The wire guide cylinders can play a guiding role in the transportation of the copper wire and make the copper wire be transported stably.

[0036] like Figure 3 As shown, a limit column 25 connected to the mounting plate 12 is provided on the side of the adjusting rod 23 away from the spring telescopic rod 24; the setting of the limit column 25 can prevent the adjusting rod 23 from swinging excessively, that is, prevent the pressing block 30 from pressing the copper wire too tightly.

[0037] like Figure 4 As shown, the moving member includes a bottom plate 26, the bottom of the bottom plate 26 is connected to an electric telescopic rod 27, the bottom of the moving frame 16 is connected to a moving block 28, the telescopic end of the electric telescopic rod 27 is connected to the moving block 28, the bottom plate 26 is provided with a moving groove for sliding the moving block 28, two sets of guide rails 29 are installed on the top of the bottom plate 26, and the bottom of the moving frame 16 is provided with a slide groove that slides with the guide rail 29;

[0038] When the electric telescopic rod 27 is in operation, the adjustable moving block 28 can move in the moving groove, thereby adjusting the position of the moving frame 16 .

[0039] like Figure 4 As shown, each group of the winding drums 15 corresponds to two groups of positioning rollers 17; the positioning rollers 17 can contact the outside of the copper wire roll. When the copper wire is detected to be broken, the positioning rollers 17 approach, and the winding drum 15 can be reversed, and the copper wire that has fallen off can be rewound onto the winding drum 15 to avoid the scattering of the fallen copper wire and affect subsequent maintenance and work.

[0040] like Figure 2 As shown, two sets of gears 20 are installed on each set of the wire rollers 19, and the end of the pressing block 30 is placed between the two sets of gears 20. The pressing block 30 cooperates with the gears 20 and can also play a limiting role, so that the copper wire can stably pass through the wire rollers 19.

[0041] The working principle of the utility model is: when the device is installed in the carbon brush forming machine, it can be used to convey and detect the copper wire. When the copper wire is conveyed from the winding drum 15 to the wire roller 19, the wire roller 19 can be driven to rotate, thereby driving the gear 20 to rotate, and the sensor 21 is turned to detect the gap and output a pulse signal. When the copper wire is broken, the wire roller 19 does not rotate, the sensor 21 cannot be read, and the signal is interrupted. The control device of the carbon brush forming machine reads the signal, which is convenient for timely stopping the machine to carry out maintenance of the copper wire conveying.

[0042] When the copper wire break is detected, the winding drum 15 will output part of the copper wire. At this time, the adjustable movable frame 16 is close to the winding drum 15. When the electric telescopic rod 27 is working, the adjustable movable block 28 moves in the movable groove, thereby adjusting the position of the movable frame 16 and adjusting the winding drum 15 to reverse at the same time. The positioning roller 17 contacts the outside of the copper wire roll, which can assist the copper wire roll to be stored on the winding drum 15.

[0043] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still fall within the protection scope of the technical solution of the present utility model.
