Abstract
Description
Technical Field
[0001] The utility model belongs to the field of steel ring guiding machines, in particular to a wire-broken and insufficient-wire automatic locking device for steel ring guiding machines. Background Art
[0002] The steel ring unwinding machine unwinds the rolled steel ring. The steel wire is first introduced from the driving disc and then led out to the floating disc. The steel wire is reciprocated and wound in an orderly manner on the driving disc and the floating disc to unwind the steel ring.
[0003] If the steel wire breaks suddenly or the steel ring is led out, the wire will be broken or insufficient. In the prior art, if the above situation occurs, the external alarm device can stop the machine and alarm, but the end of the steel wire still needs to be found manually, because the steel wire is tightened on the transmission disk and the floating disk, and floats up and down with the floating disk. Therefore, when the steel wire is broken or insufficient, the wire tension changes, and the steel wire is loose and no longer tightened on the transmission disk and the floating disk. When the end of the steel wire is found, the wire tension needs to be readjusted to make it tightened on the transmission disk and the floating disk. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a wire breakage and insufficient wire automatic locking device for a steel ring guide machine, which can monitor in real time whether the steel wire is broken or insufficient. When an abnormality is detected, the wire clamping mechanism can quickly clamp the end of the steel wire to prevent the steel wire from running and loosening, making it convenient for the operator to perform subsequent processing.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a wire breakage and insufficient wire automatic locking device of a steel ring guide machine, comprising a monitoring mechanism and a wire clamping mechanism, the monitoring mechanism is arranged at the wire inlet end of the transmission disk, and comprises a wire pressing arm and a sensor, the wire pressing arm is pulled inward to apply pressure to the steel wire, when the steel wire no longer supports the wire pressing arm, the wire pressing arm can be sensed by the sensor, the wire clamping mechanism is arranged at the wire outlet end of the transmission disk, and comprises a wire locking frame and a clamping plate for clamping the end of the steel wire.
[0006] Furthermore, the side wall of the wire locking frame extends forward to form a blocking portion corresponding to the clamping plate, and the clamping plate can be retracted on one side of the blocking portion.
[0007] Furthermore, a wire locking opening for allowing the steel wire to pass through is provided on the wire locking frame, and the wire locking opening is located between the resisting portion and the clamping plate.
[0008] Furthermore, the monitoring mechanism is arranged on the transmission wheel bracket through the B connecting frame, and the sensor is located on the inner side of the wire pressing arm.
[0009] Furthermore, a sensing sheet is provided at the side end of the thread pressing arm corresponding to the sensor.
[0010] Furthermore, the sensor is located at the lower end of the B connecting frame, the screw pressing arm is rotatably connected to the upper end of the B connecting frame, a tension spring is sleeved on the end of the screw pressing arm, and the other end of the tension spring is connected to the inner side of the screw pressing arm.
[0011] Furthermore, a retractable limiting column is provided on the inner side of the sensor for limiting the rotation path of the thread pressing arm so that the sensor corresponds to the induction sheet.
[0012] Furthermore, a clamping pad is provided on the inner wall of the resisting portion opposite to the clamping plate, and serrations for increasing friction are provided on the clamping pad.
[0013] Furthermore, the limit column adopts a spring rod of a blocking lock.
[0014] Furthermore, the wire pressing arm is in an "L" shape.
[0015] The advantages and positive effects of the utility model are:
[0016] 1. Due to the adoption of the above technical solution, compared with just the shutdown alarm, the end of the clamped steel wire can avoid subsequent problem handling, shorten the processing flow, improve work efficiency, and substantially solve the problem of broken wire and insufficient wire during the guide of the steel ring.
[0017] 2. In the monitoring mechanism, the wire pressing arm pulled inward by the tension spring presses on the top of the steel wire, exerting pressure on the steel wire. On the one hand, it strengthens the tensioning force on the steel wire. On the other hand, when the steel wire is broken or missing, the interaction force disappears, and the tension of the tension spring pulls the wire pressing arm inward, so that the sensor can sense the sensing sheet.
[0018] 3. The vertically arranged wire clamping mechanism is consistent with the guide direction of the steel wire. The steel wire passes through the wire locking mouth and the wire locking frame. The clamping plate extending outward cooperates with the resisting part to clamp the end of the steel wire, which is convenient for subsequent processing. The serrations arranged on the clamping pad increase the friction and prevent the steel wire from falling out.
[0019] 4. The limit column extending outward can limit the return position of the screw pressing arm, so that the sensing piece corresponds to the sensor and the sensing accuracy is improved. The limit column retracted inward releases the limitation of the screw pressing arm, making it difficult for the sensor to sense the screw pressing arm, thereby releasing the linkage with the screw clamping mechanism.

[0030] The utility model is further described below in conjunction with embodiments and drawings.
[0031] like Figures 1 to 3 As shown, this embodiment provides an automatic locking device for broken wire and insufficient wire in a steel ring guide machine, including a monitoring mechanism and a wire clamping mechanism. The monitoring mechanism is arranged at the wire inlet end of the transmission disk, and includes a wire pressing arm 6 which is pulled inward to apply pressure to the steel wire, and a sensor which can sense the wire pressing arm 6 when the steel wire no longer supports the wire pressing arm 6. The wire clamping mechanism is arranged at the wire outlet end of the transmission disk, and includes a wire locking frame 2 and a clamping plate 3 for clamping the end of the steel wire. When the sensor senses the wire pressing arm 6, the wire clamping mechanism clamps the steel wire.
[0032] The monitoring mechanism is arranged on one side of the transmission wheel bracket through the B connecting frame 4, the sensor is detachably connected to the lower end of the B connecting frame 4, the wire pressing arm 6 is rotatably connected to the upper end of the B connecting frame 4 through an axis, the sensor is located on the inner side of the wire pressing arm 6, a tension spring 8 is sleeved on the end of the wire pressing arm 6, the other end of the tension spring 8 is hooked with the B connecting frame 4 located on the inner side of the wire pressing arm 6, the wire pressing arm 6 is always rotated inward by the tension of the tension spring 8, and pressure is applied to the steel wire to increase the tension of the steel wire. In order to enhance the inductive sensitivity of the sensor to the wire pressing arm 6, a sensing sheet 61 is arranged on the side of the wire pressing arm 6 corresponding to the sensor;
[0033] In this embodiment, the sensor adopts a proximity switch 5, which passes through the B connecting frame 4. Nuts are threadedly connected at the front and rear ends of the proximity switch 5. The B connecting frame 4 is clamped between the two nuts to achieve the installation of the proximity switch 5. The shape of the thread pressing arm 6 is "L"-shaped.
[0034] When the steel wire is broken or insufficient, in order to make the inwardly rotating sensing piece 61 of the wire pressing arm 6 correspond to the proximity switch 5, a limit column 7 is retractably arranged on the B connecting frame 4. The limit column 7 is located on the inner side of the proximity switch 5, and is used to control the rotation path of the wire pressing arm 6. When the limit column 7 extends outward, the downwardly pressed wire pressing arm 6 is blocked by the limit column 7, and the proximity switch 5 corresponds to the sensing piece 61. The monitoring mechanism can link the external alarm device to sound an alarm. When the limit column 7 contracts inwardly, the downwardly pressed wire pressing arm 6 cannot be sensed by the sensing piece 61, and will not be linked to the alarm device and the clamping mechanism.
[0035] In this embodiment, the limiting column 7 adopts a spring rod of a blocking lock, and the spring rod extending from the blocking lock plays a limiting role;
[0036] In another embodiment, the connection position of the other end of the tension spring 8 can be changed so that the initial position of the wire pressing arm 6 is pulled inward so that the sensing sheet 61 corresponds to the sensor, or a bolt can be threadedly connected to the B connecting frame 4 and the bolt can be screwed in and out to achieve the function of limiting and releasing.
[0037] The wire clamping mechanism is arranged on the other side of the transmission wheel bracket through the A connecting frame 1. The side wall of the wire locking frame 2 extends forward to form a stopper 23 corresponding to the clamping plate 3, so that the wire locking frame 2 is "L"-shaped. The clamping plate 3 can be extended and retracted on one side of the stopper 23 through the driving device, and a wire clamping area is formed between the stopper 23 and the clamping plate 3. When the sensor senses the wire pressing arm 6, the driving device drives the clamping plate 3 to be pushed outward toward the stopper, so that the steel wire is clamped between the stopper and the clamping plate 3. The driving device adopts a cylinder 31, and the clamping plate 3 is arranged on the push rod of the cylinder 31;
[0038] In this embodiment, the wire locking frame 2 is vertically set up, and the steel wire at the lead-out end passes through the wire locking frame 2. On the wire locking frame 2, a wire locking opening 22 for the steel wire to pass through in parallel is provided between the blocking portion and the clamping plate 3;
[0039] In another embodiment, the wire locking frame 2 can be horizontally arranged, and the steel wire at the lead-out end passes between the resisting portion and the clamping plate 3 .
[0040] In order to increase the friction force on the steel wire and prevent the steel wire from slipping out after clamping, a clamping pad 21 is provided on the inner wall opposite to the blocking portion 23 and the clamping plate 3, and a sawtooth for increasing friction is provided on the clamping pad 21. In this embodiment, a plurality of sawtooths are vertically arranged.
[0041] The working process of this example:
[0042] The steel wire is introduced through the transmission disk and led out from the wire locking port 22 of the wire locking frame 2. The tension spring 8 is stretched, causing the wire pressing arm 6 to press down on the top of the steel wire, generating pressure on the steel wire. If the steel wire is broken or insufficient, the pressure disappears, and the tension spring 8 retracts to drive the wire pressing arm 6 to rotate inward until it abuts against the limit column 7. The sensor sheet 61 corresponds to the proximity switch 5. The proximity switch 5 receives the sensing signal and links with the external alarm device to realize the alarm, and pushes the push rod of the cylinder 31 outward, so that the end of the steel wire is clamped between the resisting portion 23 and the clamping plate 3.
[0043] If you do not want to alarm or clamp the wire when it is short or broken, you can rotate the lock to retract the spring rod, i.e., the limit column 7. When the wire is broken or short, the tension spring 8 drives the wire pressing arm 6 to rotate inward, and the sensor sheet 61 does not correspond to the proximity switch 5.
[0044] The above describes one or more embodiments of the utility model in detail, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model shall still fall within the scope of the patent coverage of the utility model.
