Description

Technical Field

[0001] This utility model belongs to the field of wire breakage protection technology for wire winding machines, and in particular relates to an emergency clamping mechanism for wire breakage in copper wire winding machines. Background Technology

[0002] A copper wire winding machine is a specialized industrial device used to neatly and tightly wind continuously produced copper wire (such as drawn or annealed copper wire) onto a spool, reel, or coil. It typically includes a wire feeding device (supplying the copper wire), a precision tension control system (ensuring constant tension during winding and preventing damage or stretching of the copper wire), a precision wire laying mechanism (guiding the copper wire to move laterally according to a specific pattern, achieving neat layered arrangement), and a high-speed rotating take-up spindle (driving the take-up reel to rotate for winding). Its core objective is to efficiently and automatically complete the winding of copper wire, forming neat coils that are easy to store, transport, and subsequently process. It is a key piece of equipment at the end of the copper wire processing production line (such as enameled wire, cable core wire, etc.).

[0003] The emergency clamping mechanism for wire breakage on a winding machine is a safety device that operates instantly and is automatically triggered when the production material (such as cable, steel wire, optical fiber, etc.) suddenly breaks. This mechanism usually uses the sudden drop in tension, position shift, or speed change generated at the moment of wire breakage as a trigger signal. It drives the actuators such as grippers, pressure blocks, or friction wheels through a power source such as springs, pneumatic or hydraulic power to trigger the clamping force.

[0004] An existing clamping mechanism works with a guide wheel. After a trigger signal, the pressure plate is pneumatically pushed to clamp the guide wheel. However, the winding machine runs at a high speed, and in order to prevent wear between the pressure plate and the copper wire during winding, a certain distance is set between them. When the copper wire breaks, due to the limited reaction time, the instantaneous elastic force can easily cause the copper wire to detach without being clamped, thus failing to achieve the purpose of emergency response and having poor reliability.

[0005] To address the aforementioned issues, this application proposes an emergency clamping mechanism for broken wires in a copper wire winding machine. Utility Model Content

[0006] The purpose of this utility model is to provide an emergency clamping mechanism for broken wires in a copper wire winding machine. By using a release wheel to actively loosen the wire and a clamping wheel to apply double braking, the problem of copper wire detachment due to inertia during high-speed winding is solved.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to an emergency clamping mechanism for broken copper wire in a winding machine. The mechanism includes a winding machine body with a chassis and an I-beam wheel and a wire-laying mechanism mounted on the side of the chassis. A control module is also installed on the top of the chassis. The clamping mechanism is mounted on a sliding block within the wire-laying mechanism and reciprocates following the mechanism's drive. The clamping mechanism includes a guide plate and a support plate mounted on the upper end of the guide plate. A release wheel, a trigger wheel, and a clamping wheel are located on one side of the guide plate along the copper wire winding path. The upper end of the release wheel is connected to a cylinder via a linkage plate. A clamping assembly is located directly above the clamping wheel and connected to the cylinder via the linkage plate. A sensor that cooperates with the trigger wheel is located on the rear side of the guide plate. When the copper wire breaks, the trigger wheel is sensed by the sensor under the action of a spring. Subsequently, the cylinder drives the release wheel to move downwards, releasing the copper wire. Simultaneously, the cylinder also drives the clamping assembly to clamp the copper wire on the clamping wheel.

[0009] Furthermore, a first guide block is provided on one side of the release wheel for rotational engagement, and a release guide groove is fixedly provided in the guide plate for sliding engagement with the first guide block. A first pressure rod is fixedly installed on the upper end of the first guide block, penetrating the upper end of the release guide groove and fixed to the linkage plate.

[0010] Furthermore, a second guide block is provided on one side of the trigger wheel for rotational engagement, a trigger guide groove is fixedly provided in the guide plate for sliding engagement with the second guide block, a guide rod is fixedly installed on the upper end of the second guide block for passing through the trigger guide groove, and the spring abuts against the top of the trigger guide groove and the guide rod.

[0011] Furthermore, a support frame is fixed to one side of the guide plate, and the clamping wheel is mounted between the support frame and the guide plate in a rotating manner. An extension sleeve is fixed to one side of the clamping wheel, and a rubber ring is provided on the outside of the extension sleeve. The bottom of the clamping assembly has a brake block, which is pressed against the extension sleeve under the drive of the cylinder.

[0012] Furthermore, the clamping assembly also has a wire clamping block at the bottom. The bottom of the wire clamping block is arc-shaped and the cross-section is "V". The wire clamping block clamps the copper wire by cooperating with the pressure wheel through the drive of the cylinder.

[0013] Furthermore, a second pressure rod is fixed to the upper end of the clamping assembly, the second pressure rod is fixed to the linkage plate, the cylinder is fixedly installed on the top of the support plate and its output end is fixed to the linkage plate, and a plurality of linear bearings are installed on the upper end of the support plate and slide in cooperation with the first pressure rod and the second pressure rod respectively.

[0014] Furthermore, a fixing seat is fixed to the upper end of the sliding block, and a base plate is provided at the bottom of the guide plate to be fixedly installed with the fixing seat.

[0015] Furthermore, a stop bar is fixed to the top of the support frame.

[0016] This utility model has the following beneficial effects:

[0017] This utility model sets a release wheel on the copper wire winding path and then connects the release wheel to a cylinder. When the sensor at the upper end of the trigger wheel is triggered, the cylinder can drive the release wheel to move down while pushing the clamping group. At this time, the copper wire is released, providing more sufficient reaction time for the clamping group and the clamping wheel, thereby improving the reliability of the emergency clamping mechanism.

[0018] This invention not only features a clamping block to hold the copper wire, but also a brake block and a rubber ring to brake the pressure wheel, thereby preventing the inertia of the pressure wheel from accelerating the detachment of the copper wire during high-speed winding and further improving the reliability of emergency clamping.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figures 1-7 As shown, this utility model is an emergency clamping mechanism for broken copper wire in a winding machine. It includes a winding machine body 1, a housing 11, and a bobbin 12 and a wire-laying mechanism 13 mounted on the side of the housing 11. Inside the housing 11 is a motor that drives the bobbin 12 and the wire-laying mechanism 13. When driven, the bobbin 12 rotates to wind the wire. When driven, the wire-laying mechanism 13 drives a sliding block 131 to reciprocate for neatly winding the copper wire on the bobbin 12. The upper end of the sliding block 131 is welded... Alternatively, a horizontal and symmetrical fixing seat 1311 is bolted on. The bottom of the conductor plate 2 is symmetrically provided with a base plate 21 and the fixing seat 1311 are fixedly installed with bolts. A control module 14 is also installed on the top of the chassis 11. The clamping mechanism is installed on the sliding block 131 in the cable laying mechanism 13 and follows the drive of the cable laying mechanism 13 to reciprocate. By installing the clamping mechanism on the sliding block 131, it can follow the displacement of the copper wire and ensure that it is always in a ready clamping state. It can act in time when the wire is broken.

[0033] Specifically, the clamping mechanism includes a wire plate 2 and a support plate 3 installed on the upper end of the wire plate 2. The wire plate 2 and the support plate 3 are fixedly installed through connecting holes and bolts. A release wheel 4, a trigger wheel 5, and a clamping wheel 6 are provided on one side of the wire plate 2 along the copper wire winding path. The upper end of the release wheel 4 is connected to the cylinder 32 through a linkage plate 7. A clamping group 8 is provided directly above the clamping wheel 6 and is connected to the cylinder 32 through the linkage plate 7. In this embodiment, the release wheel 4 and the clamping group 8 are connected to the cylinder 32 simultaneously through the linkage plate 7. The release wheel 4 serves to loosen the wire and provide sufficient time for clamping. After the clamping group 8 is pressed down, it cooperates with the clamping wheel 6 to clamp and prevent the copper wire wound on the I-beam 12 from loosening.

[0034] Specifically, a second guide block 51 is provided on one side of the trigger wheel 5 for rotational engagement. A trigger guide groove 23 is fixedly provided in the guide plate 2 for sliding engagement with the second guide block 51. A guide rod 52 is fixedly installed on the upper end of the second guide block 51, which passes through the trigger guide groove 23. The sliding between the trigger guide groove 23, the second guide block 51, and the guide rod 52 is used to support the rotation and vertical sliding of the trigger wheel 5. A spring 53 is pressed against the top of the trigger guide groove 23 and the guide rod 52. Under normal conditions, the spring 53 drives the trigger wheel 5 to the lowest position, thereby ensuring that the second guide block 51 can be sensed by the sensor 9 in time after the copper wire is unloaded.

[0035] Furthermore, a sensor 9 is provided on the rear side of the lead wire plate 2 to cooperate with the trigger wheel 5. The sensor 9 is fixed to the bottom side of the trigger guide groove 23. When the copper wire is wound, the spring 53 plays a certain tension control role. When the copper wire is broken, the spring 53 pushes the guide rod 52 down, so that the second guide block 51 contacts the detection surface of the sensor 9. After the sensor 9 is sensed, it directly feeds the signal back to the control module 14. Then, the control module 14 controls the I-beam wheel 12 and the wire laying mechanism 13 to stop and start the cylinder 32 to work.

[0036] Specifically, a first guide block 41 is provided on one side of the release wheel 4 for rotational engagement. A release guide groove 22 is fixedly provided in the guide plate 2 for sliding engagement with the first guide block 41. A first pressure rod 42 is fixedly installed on the upper end of the first guide block 41, penetrating the upper end of the release guide groove 22 and fixed to the linkage plate 7. In this embodiment, the vertical sliding engagement of the first guide block 41 and the release guide groove 22 provides a stable movement space for the release wheel 4, while the penetration of the first pressure rod 42 into the release guide groove 22 plays a certain guiding role. At the same time, in order to link the lifting and lowering of the release wheel 4 with the cylinder 32 connected to the linkage plate 7.

[0037] Specifically, a support frame 24 is bolted to one side of the conductor plate 2. The clamping wheel 6 is mounted between the support frame 24 and the conductor plate 2 in a rotating manner. The support frame 24 provides reliable support for the clamping wheel 6, thereby ensuring the structural stability during clamping. An extension sleeve 61 is fixed to one side of the clamping wheel 6. A rubber ring 62 is provided on the outside of the extension sleeve 61. The extension sleeve 61 can be fixed to the clamping wheel 6 by welding or injection molding. The rubber ring 62 can be connected to the outside of the extension sleeve 61 by interference fit or concave-convex rib structure. A brake block 82 is fixedly installed at the bottom of the clamping assembly 8 by snap-fit, glue bonding or other methods. The brake block 82 is pressed against the extension sleeve 61 by the cylinder 32. This pressing fit serves to brake the clamping wheel 6 and prevent the inertia of the clamping wheel 6 from accelerating the separation of the copper wire. In order to ensure the contact area of ​​friction, the bottom of the clamping block 81 is arc-shaped.

[0038] Furthermore, a stop bar 241 is fixed on the top of the support frame 24. The stop bar 241 can prevent the copper wire from detaching from the outside of the clamping wheel 6 after it breaks, ensuring that the copper wire stays between the clamping wheel 6 and the clamping group 8 after the wire breaks. At the same time, there is space for the copper wire to move between the top of the stop bar 241 and the clamping group 8 in the reset state, so as not to affect the wiring.

[0039] Specifically, the bottom of the clamping assembly 8 is also fixedly installed with a wire clamping block 81 made of wear-resistant rubber by means of snap-fitting, adhesive bonding, etc. The bottom of the wire clamping block 81 is arc-shaped and the cross section is "V". The wire clamping block 81 is driven by the cylinder 32 and cooperates with the pressure wheel 6 to clamp the copper wire. In this embodiment, the arc shape of the bottom of the wire clamping block 81 is to increase the clamping area of ​​the copper wire, and the "V" shape can adapt to the clamping of copper wires of different sizes. The rubber clamping assembly 8 has high friction and good toughness, thereby ensuring the clamping effect of the copper wire.

[0040] Specifically, a second pressure rod 83 is fixed to the upper end of the clamping assembly 8. The second pressure rod 83 is fixed to the linkage plate 7. The cylinder 32 is fixedly installed on the top of the support plate 3 and its output end is fixed to the linkage plate 7. Several linear bearings 31 are installed on the upper end of the support plate 3 and slide in cooperation with the first pressure rod 42 and the second pressure rod 83 respectively.

[0041] A specific application of this embodiment is as follows: When the copper wire is not being wound under normal conditions, the release wheel 4 and the clamping group 8 are in the highest position under the action of the cylinder 32, and the trigger wheel 5 is in the lowest position under the action of the spring 53. The copper wire is arranged along the release wheel 4, the trigger wheel 5, and the pressing wheel 6, the copper wire is tightened and fixedly connected to the I-beam wheel 12. After the copper wire is tightened, the trigger wheel 5 is moved upward, the spring 53 is compressed, and the second guide block 51 is disengaged from the sensor 9.

[0042] When the operation control module 14 starts the winding operation, the I-beam 12 rotates under the action of the motor inside the housing 11. The copper wire is wound up as the I-beam 12 rotates. The sliding block 131 moves under the drive of the motor inside the housing 11 to neatly wind up the copper wire. When the control module 14 is turned on, the sensor 9 is powered on. When the copper wire is wound up, the release wheel 4, the trigger wheel 5, and the pressure wheel 6 are all in a rolling state.

[0043] like Figure 1 , Figure 2 , Figure 4 The cut-off portion on the right side of the copper wire shown is only for reference when the copper wire is laid out. In actual production, the right side of the copper wire is connected to the end of the copper wire production line. When the copper wire is disconnected at the release wheel 4 and the traction position at the end of the production line, the trigger wheel 5 moves down automatically under the action of the spring 53. After the sensor 9 senses the second guide block 51, it transmits the signal to the control module 14 on the main body 1 of the winding machine. The control module 14 stops the operation of the machine box 11 and the winding mechanism 13. At the same time, the cylinder 32 is activated to push down the linkage plate 7. When the release wheel 4 moves down, it loosens the copper wire to avoid tension. The clamping block 81 moves down and cooperates with the pressure wheel 6 to clamp the copper wire. The brake block 82 moves down and contacts the rubber ring 62 to brake the pressure wheel 6. The copper wire is clamped.

[0044] During reset, the cylinder 32 is moved upward by the control module 14, and then the copper wire is manually re-threaded between the release wheel 4, the trigger wheel 5, and the clamping wheel 6 to re-wire the machine before restarting.
