Description

Technical Field

[0001] The present application relates to the field of wire cutting technology, and in particular to a winding device and a wire cutting machine. Background Art

[0002] When using a wire-feed reciprocating wire cutting machine, when replacing the molybdenum wire, the molybdenum wire in the winding reel passes through the lowest guide wheel and is fixed to the wire storage drum. At this time, the guide wheel only plays a guiding role, and the molybdenum wire on the winding reel relies on the rotation and lateral movement of the wire storage drum to wind the molybdenum wire onto the wire storage drum. When the number of meters of molybdenum wire on the wire storage drum reaches the cutting requirement, the wire storage drum stops rotating. At this time, the winding reel will continue to rotate due to inertia, and a large amount of molybdenum wire in the winding reel will be thrown out and entangled and folded with the surrounding structure of the winding reel, making it unusable, causing manual cutting of these entangled and folded molybdenum wires for waste discharge, which is time-consuming and wastes a large amount of molybdenum wire, resulting in the consumption of auxiliary materials. Utility Model Content

[0003] The purpose of the present application is to provide a winding device, which can prevent the phenomenon of wire overlap when the molybdenum wire is replaced.

[0004] Other features and advantages of the present application will become apparent from the following detailed description, or may be learned in part by the practice of the present application.

[0005] According to one aspect of an embodiment of the present application, a winding device is provided, the device comprising a motor, a wire storage drum, a current detection element, a winding reel, a clamping mechanism, and a controller;

[0006] The wire storage drum is connected to the output end of the motor. When the power supply circuit of the motor is energized, the output end of the motor drives the wire storage drum to rotate.

[0007] The current detection element is electrically connected to the power supply circuit of the motor;

[0008] The wire is wound on the winding drum, and the wire is wound on the wire storage drum as the wire storage drum rotates;

[0009] The clamping mechanism is arranged on one side of the cable reel;

[0010] The controller is connected with the current detection element and the clamping mechanism, and is used for controlling the clamping mechanism to clamp the wire reel and the wire when receiving a signal from the current detection element indicating that the power supply line of the motor is powered off.

[0011] Optionally, the clamping mechanism includes a cylinder and a solenoid valve, the cylinder body of the cylinder is arranged on one side of the winding reel, the piston rod of the cylinder is facing the winding reel, the solenoid valve is connected to the air circuit of the cylinder, and the controller is connected to the solenoid valve.

[0013] Optionally, a reset button is provided on the solenoid valve.

[0024] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be more comprehensive and complete and fully convey the concept of the example embodiments to those skilled in the art.

[0025] It should be noted that the "multiple" mentioned in this article refers to two or more. "And / or" describes the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0026] The implementation details of the technical solution of the embodiment of the present application are described in detail below:

[0027] The present application embodiment provides a winding device, such as Figure 1 , 2 As shown, it includes a motor 1, a wire storage drum 2, a current detection element 3, a winding drum 4, a clamping mechanism 5, and a controller 6;

[0028] The wire storage drum 2 is connected to the output end of the motor 1. When the power supply circuit of the motor 1 is energized, the output end of the motor 1 drives the wire storage drum 2 to rotate.

[0029] The current detection element 3 is electrically connected to the power supply circuit of the motor 1;

[0030] The wire 7 is wound on the wire reel 4, and the wire 7 is wound on the wire storage drum 2 as the wire storage drum 2 rotates;

[0031] The clamping mechanism 5 is arranged on one side of the cable reel 4;

[0032] The controller 6 is connected to the current detection element 3 and the clamping mechanism 5 , and is used to control the clamping mechanism 5 to clamp the cable reel 4 and the wire 7 when receiving a signal from the current detection element 3 indicating that the power supply line of the motor 1 is powered off.

[0033] It is understandable that the cable reel 4 can rotate. For example, the cable reel 4 can be installed on a fixed rotating shaft, and the cable reel 4 can rotate relative to the rotating shaft. Alternatively, the cable reel 4 is installed on a rotatable rotating shaft and rotates with the rotating shaft, which is not specifically limited here. The device is used to wind the wire 7 on the cable reel 4 onto the wire storage drum 2. First, one end of the wire 7 is connected to the wire storage drum 2. When the motor 1 drives the wire storage drum 2 to rotate, the wire 7 is wound on the wire storage drum 2, and the cable reel 4 rotates under the pull of the wire 7. When the wire 7 on the wire storage drum 2 reaches the set amount, the motor 1 is powered off and stops operating, the current detection element 3 detects that the power supply line of the motor 1 is powered off, and sends a signal to the controller 6. The controller 6 controls the clamping mechanism 5 to clamp the wire 7 on the winding reel 4, and applies a force to stop the axial rotation of the winding reel 4, so that the winding reel 4 stops rotating quickly, avoiding the problem that the winding reel 4 continues to rotate due to inertia, causing the wire 7 to be thrown out of the winding reel 4 and entangled and folded with the surrounding structure of the winding reel 4, saving the time of manual processing of cutting the entangled and folded wire 7, and reducing the loss of wire 7.

[0034] It is understandable that due to the perspective, Figure 1 The motor in is blocked by the wire storage drum 2 and is therefore not shown.

[0035] In some feasible implementations, Figure 2 As shown, the clamping mechanism 5 includes a cylinder 8 and a solenoid valve 9. The cylinder body of the cylinder 8 is arranged on one side of the cable reel 4, the piston rod of the cylinder 8 faces the cable reel 4, the solenoid valve 9 is connected to the air path of the cylinder 8, and the controller 6 is connected to the solenoid valve 9, and is used to control the solenoid valve 9 to open the air path of the cylinder 8 when receiving the signal sent by the current detection element 3 that the motor 1 stops running, so as to drive the piston rod to extend to clamp the cable reel 4.

[0036] The solenoid valve 9 controls the extension and retraction of the cylinder 8. When the cylinder 8 is extended, the piston rod presses the cable reel 4 and the wire 7, so that the cable reel 4 stops rotating, and the wire 7 is firmly pressed against the cable reel 4.

[0037] In some feasible implementations, a rubber sleeve is provided on the piston rod of the cylinder 8. The rubber sleeve has strong friction and can effectively increase the pressing force on the wire 7 and the winding reel 4 to avoid excessive friction and wear of the wire 7.

[0038] In some feasible implementations, a reset button is provided on the solenoid valve 9. Before the wire 7 on the winding reel 4 is wound onto the wire storage drum 2, the reset button is pressed to retract and reset the piston rod so that the winding reel 4 can rotate.

[0039] In some feasible implementations, Figure 1As shown, it also includes more than one guide wheel 10, which is arranged between the winding drum 4 and the wire storage drum 2. After the wire 7 passes through more than one guide wheel 10 in sequence, it is wound on the wire storage drum 2 as the wire storage drum 2 rotates. Figure 2 As shown, two guide wheels 10 tighten the wire 7 between the wire reel 4 and the wire storage drum 2. After passing through the guide wheels 10, the wire 7 forms an S-shaped track and is fixed to one end of the wire storage drum 2. The motor 1 drives the wire storage drum 2 to rotate, which can drive the wire reel 4 to rotate, and the wire 7 on the wire reel 4 is wound onto the wire storage drum 2. The guide wheel 10 increases the resistance of the wire 7 and increases the back tension when the wire reel 4 winds the wire 7 onto the wire storage drum 2, thereby avoiding the occurrence of wire overlap and saving the time for processing the wire overlap on the wire storage drum 2.

[0040] In some feasible embodiments, a groove is provided on the side of the guide wheel 10. Since the wire storage drum 2 needs to move axially while rotating in order to evenly wind the wire 7 on the wire storage drum 2, a groove is provided on the side of the guide wheel 10 to prevent the wire 7 from escaping from the guide wheel 10.

[0041] In some feasible implementations, the current detection element 3 is a Hall element, which is installed on the three-phase conductor of the motor 1. When the three-phase conductor is powered off, the motor 1 stops running and drives the wire storage drum 2 to stop rotating. The Hall element detects that the three-phase conductor is powered off and sends a signal to the controller 6. The controller 6 controls the clamping mechanism 5 to clamp the wire 7 on the winding drum 4, thereby preventing the winding drum 4 from rotating and compressing the wire 7. The Hall element has a firm structure, small size, light weight, long life, easy installation, low power consumption, high frequency, vibration resistance, and is not afraid of pollution or corrosion from dust, oil, water vapor, salt spray, etc., and can adapt to the use environment of wire cutting.

[0042] In one embodiment of the present application, the controller 6 may be a PLC controller.

[0043] It should be noted that the winding device proposed in the embodiment of the present application can be applied to the field of wire cutting technology. For example, in a wire cutting device that uses molybdenum wire as the cutting wire, the molybdenum wire is wound on a wire reel 4 for wire cutting. When the molybdenum wire needs to be replaced, the molybdenum wire wound on the wire reel 4 is led to the wire storage drum 2. The motor 1 drives the wire storage drum 2 to rotate while winding the molybdenum wire around the wire storage drum 2. When the wire storage drum 2 stops rotating, the wire reel 4 will continue to rotate due to inertia, and the molybdenum wire will continue to be pulled out and wound around other components, causing equipment operation failure and molybdenum wire waste.

[0044] Therefore, with the same inventive concept, the embodiment of the present application also provides a wire cutting machine, including the winding device of the above embodiment. The cutting wire of the wire cutting machine can be molybdenum wire, that is, the wire material 7 wound on the winding drum 4 is molybdenum wire; the wire storage drum 2 is installed in the wire cutting machine, and the molybdenum wire stored on the wire storage drum 2 is used for wire cutting.

[0045] When the molybdenum wire on the wire storage drum 2 is used up, it is necessary to replace the molybdenum wire, fix the molybdenum wire on the winding drum 4 to the wire storage drum 2, and after the motor 1 is started, it drives the wire storage drum 2 to rotate and reciprocate along the axial direction. The molybdenum wire is evenly wound around the wire storage drum 2 and drives the winding drum 4 to rotate. When the motor 1 stops, when the current detection element 3 detects the signal that the power supply line of the motor 1 is powered off, the clamping mechanism 5 is controlled to press the molybdenum wire on the winding drum 4 and stop the winding drum 4 from rotating, thereby preventing the winding drum 4 from continuously rotating due to inertia and causing the molybdenum wire to be thrown out, which is easy to cause production risks and waste of molybdenum wire.

[0046] It is understandable that when replacing molybdenum wire in current wire cutting equipment, the molybdenum wire on the wire storage tube may overlap due to the unstable left-right fluctuation of the molybdenum wire during the winding process. Subsequent processing of the overlapped wire requires manual separation of the molybdenum wires one by one, which is time-consuming and laborious. The present application embodiment guides the molybdenum wire through the guide wheel 10, which only plays a guiding role. For example, as Figure 1 As shown, after the molybdenum wire changes its trajectory from the winding drum 4 through the guide wheel 10, an S-shaped trajectory is formed, which increases the back tension of the molybdenum wire when it is wound on the wire storage drum 2, ensuring that no wire overlap occurs when the molybdenum wire is wound from the winding drum 4 to the wire storage drum 2.

[0047] It is understandable that when the clamping mechanism 5 clamps the molybdenum wire and the wire reel 4, the molybdenum wire can be cut manually.

[0048] Compared with the prior art, the wire cutting machine provided in the embodiment of the present application saves the time for manually handling the stacked wires on the wire storage drum, saves the time for manually handling the cutting, winding and folded molybdenum wires, reduces the loss of molybdenum wire, saves the waste of auxiliary materials, speeds up the replacement of molybdenum wire, increases the sample cutting time of the wire cutting equipment, improves the utilization rate of the wire cutting equipment, improves the economic benefits, and improves the safety of the molybdenum wire replacement process.

[0049] It should be understood that the present application is not limited to the precise structures that have been described above and shown in the drawings, and that various modifications and changes may be performed without departing from the scope thereof. The scope of the present application is limited only by the appended claims.
