Technical Field
[0001] This utility model relates to the field of wire cutting machine technology, and in particular to a balance guide wheel wire laying module for a wire cutting machine. Background Technology
[0002] The wire unwinding and take-up device of a wire cutting machine is generally mounted on the frame and typically includes two sets of guide wheel modules and two sets of take-up / unwinding assemblies. Each guide wheel module and take-up / unwinding assembly corresponds one-to-one and is symmetrically positioned at both ends of the main roller. Each guide wheel module includes a tension guide wheel and a wire feeding wheel. The tension guide wheel is mounted on the mounting plate by a tension arm that swings. The tension arm is driven by a tension motor, which causes the tension guide wheel to swing, thereby achieving the tensioning operation of the metal cutting wire. Each take-up / unwinding assembly has a winding guide wheel and a servo motor that drives the winding guide wheel to rotate. The servo motor drives the winding wheel to rotate at a certain speed, realizing the unwinding and take-up / winding operations of the cut metal wire.
[0003] During operation, the take-up and unwind assembly on one side is used for feeding the money, while the take-up and unwind assembly on the other side is used for winding up the wire. For example... Figure 1 As shown, the metal wire to be cut by the wire cutter is fed out by the winding guide wheel on the unwinding side, passes through the wire feeding wheel of the guide wheel module on that side, is tensioned by the tensioning guide wheel, and then fed into the main roller for cutting. After cutting, it passes through the guide wheel module on the other side, through the tensioning guide wheel and the wire feeding wheel on that side, and is then wound back by the guide wheel of the take-up and unwinding assembly on that side. During this process, in order to ensure that the cut metal wire on the winding guide wheel is evenly and flatly distributed, the wire feeding wheel is driven by the linear module to reciprocate laterally along the axial direction of the winding wheel. At this time, in order to control the reciprocating laterally movement speed of the wire feeding wheel so that it can cooperate with the winding guide wheel, a sensor is usually positioned between the wire feeding wheel and the winding guide wheel. This sensor is usually equipped with two copper rod detection ends. The cut metal wire connected between the wire feeding wheel and the winding guide wheel passes through the two copper rod detection ends and is detected by the sensor signal. During this process, because the wire guide wheel moves back and forth horizontally, the cutting metal wire may rub against the detection ends of the copper rods on both sides of the sensor during the movement, causing sensor wear and requiring the line to be stopped for maintenance.
[0004] To address this issue, it is necessary to further improve the design of the guide wheel cable routing based on the existing wire take-up and untake-up device. Utility Model Content
[0005] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a balance guide wheel wire laying module for a wire cutting machine, which can still ensure that the wire laying wheel can effectively, smoothly and evenly carry out wire take-up and unwinding operations without the need for a sensor with a copper rod, so that the wire laying on the surface of the winding guide wheel is evenly and flatly distributed.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a balance guide wheel wire winding module for a wire cutting machine, used for winding and unwinding the cut metal wire of the wire cutting machine, including a mounting plate, a tension wheel, a filter wheel, a wire winding wheel, and a straight module; the mounting plate is fixed on the frame, and the tension wheel is adjustablely connected to the mounting plate via a tension arm; the filter wheel is rotatably connected to the mounting plate, the tension wheel is located above one side of the filter wheel, and the wire winding wheel is located on the other side of the filter wheel with its rotation plane parallel to the rotation plane of the filter wheel; the straight module is set on the mounting plate and has a horizontal slider that slides back and forth in the horizontal direction; a sensor mounting base is fixed on the horizontal slider, a weighing sensor is set on the sensor mounting base, a weighing connecting frame is fixed to the detection end of the weighing sensor, and the wire winding wheel is rotatably set on the weighing connecting frame.
[0007] In the above scheme, compared to the original distribution of guide wheels for the tensioning wheel and the winding wheel, a filter wheel is installed between the tensioning wheel and the winding wheel. The monitoring of the original position signal of the cutting metal wire is changed to monitoring the weight of the winding wheel. By monitoring the combined force of the weight of the winding wheel at its position and the pressure of the passing cutting metal wire, it is determined whether the rotational speed of each guide wheel and the operation of the motor in the current winding device meet the requirements for smooth and uniform winding of the lower winding guide wheel. This structure eliminates the need for sensors with copper rod detection ends, and the cutting metal wire does not contact the sensor, thus avoiding wear on the sensor during winding and unwinding. Simultaneously, the monitoring signal is more stable, reasonable, and reliable.
[0008] Furthermore, the highest point of the filter wheel and the highest point of the winding wheel are at the same height, meaning that the cutting metal line between the filter wheel and the winding wheel forms a straight line parallel to the reciprocating motion direction of the winding wheel. This reduces the variables in the resultant force calculation at the winding wheel and simplifies the calculation of the target value.
[0009] Furthermore, in order to filter the cutting metal wire between the tension wheel and the cable tray wheel and avoid interference from the cutting metal wire caused by the rotation of the guide wheel on the resultant force at the cable tray wheel, when the tension wheel swings to its highest position, the height of its lowest point is lower than the height of the highest point of the filter wheel.
[0010] Furthermore, the linear module includes a servo motor, a horizontal lead screw, and a horizontal track. The horizontal lead screw and the horizontal track are both arranged parallel to the line connecting the highest points of the filter wheel and the winding wheel. The servo motor is positioned on the mounting plate via a motor mounting base. The output end of the servo motor is connected to the horizontal lead screw via a coupling. The other end of the horizontal lead screw is limited by a lead screw mounting base and the mounting plate. The outer surface of the horizontal lead screw has external threads. The horizontal slider is threadedly connected to the horizontal lead screw and slidably connected to the horizontal track.
[0011] Preferably, in the tension adjustment of the tension wheel, a tension motor is fixed on the mounting plate, and a tension arm is rotatably connected to the mounting plate. The output end of the tension motor is connected to the hinge end of the tension arm and drives the tension arm to swing around the hinge end as the swing center. The tension wheel is rotatably mounted on the far hinge end of the tension arm.
[0012] The beneficial effects of this utility model are that the wire cutting machine balance guide wheel wire laying module provided by this utility model has a reasonable structural design. It adopts a weighing sensor to measure the weight of the wire laying wheel and the resultant force generated by the pressure of the wire cutting on the wire laying wheel. This confirms whether the rotation speed, reciprocating lateral speed and winding guide wheel rotation of each guide wheel in the wire laying module are matched. This ensures that when the wire is cut and wound, the winding guide wheel can be wound and unwound smoothly and evenly. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.
[0019] like Figure 2 and Figure 3The wire cutting machine with a balanced guide wheel wire laying module shown is the preferred embodiment of this utility model.
[0020] The wire cutting machine uses a balanced guide wheel wire winding module for unwinding and winding the cut metal wire 19. Each wire winding module has a corresponding winding module below it. The wire winding module includes a mounting plate 15, a tensioning wheel 2, a filter wheel 3, a wire winding wheel 5, and a straight-line module. The mounting plate 15 is fixed to the frame and is used to position and set the various guide wheels and corresponding motors and modules. Figure 2 From left to right, the mounting plate 15 is provided with tension wheel 2, filter wheel 3 and cable wheel 5 in sequence.
[0021] The positioning and tension adjustment of the tension wheel 2 are achieved through the tension motor 1 and the tension arm 14. Specifically, the tension motor 1 is fixed on the mounting plate 15, and the tension arm 14 is rotatably connected to the mounting plate 15 via a bearing. The bearing end is the hinge end of the tension arm 14. The output end of the tension motor 1 is connected to the hinge end of the tension arm 14 and drives the tension arm 14 to swing around the hinge end as the swing center. The tension wheel 2 is rotatably mounted on the far hinge end of the tension arm 14. In the actual swing adjustment of the tension, limit rods 13 can be designed on both sides above the hinge end of the tension arm 14 corresponding to the swing direction to limit the swing adjustment range of the tension arm 14.
[0022] The filter wheel 3 is rotatably mounted on the mounting plate 15 and located to the lower right of the tensioning guide wheel. The cable guide wheel 5 is located on the other side of the filter wheel 3, and its rotation plane is parallel to the rotation plane of the filter wheel 3.
[0023] In the positioning of the filter wheel 3, tension guide wheel, and wire guide wheel 5, to ensure greater stability of the cut metal wire 19 during winding and unwinding, the rotation planes of these three guide wheels are located on the same plane. During the winding and unwinding movement of the cut metal wire 19, in order to filter the cut metal wire 19 between the tension wheel 2 and the wire guide wheel 5 and prevent the cutting metal wire 19's movement caused by the rotation of the guide wheel from interfering with the resultant force at the wire guide wheel 5, when the tension wheel 2 swings to its highest position, the height of its lowest point is lower than the height of the highest point of the filter wheel 3. After the cut metal wire 19 passes through the tension wheel 2, it forms an upward angle with the filter wheel 3, thus forming a further tensioning and filtering operation to prevent fluctuations.
[0024] Meanwhile, in order to reduce the variables in the resultant force calculation at the winding wheel 5 and simplify the calculation of the target value, the highest point of the filter wheel 3 and the highest point of the winding wheel are at the same height. That is, the highest point of the filter wheel 3 and the highest point of the winding wheel are at the same height. The cutting metal line 19 between the filter wheel 3 and the winding wheel forms a straight line parallel to the reciprocating motion direction of the winding wheel 5, ensuring the stability of the force and reducing the resultant force error that may be caused by the angle change during the motion process.
[0025] The positioning and reciprocating lateral movement of the wire guide wheel 5 are achieved through a linear module. Specifically, the linear module is mounted on the mounting plate 15 and includes a servo motor 9, a horizontal slider 8, a horizontal lead screw 11, and a horizontal track 17. Corresponding to the positional requirements of the wire guide wheel 5, the horizontal lead screw 11 and the horizontal track 17 are both parallel to the line connecting the highest point of the filter wheel 3 and the winding wheel. The servo motor 9 is positioned on the mounting plate 15 via a motor mounting base. The output end of the servo motor 9 is connected to the horizontal lead screw 11 via a coupling 10. The other end of the horizontal lead screw 11 is limited to the mounting plate 15 via a lead screw mounting base 12. The outer surface of the horizontal lead screw 11 has external threads. The horizontal slider 8 is threadedly connected to the horizontal lead screw 11 and slidably connected to the horizontal track 17. A sensor mounting base 7 is fixed on the horizontal slider 8, and a weighing sensor 6 is mounted on the sensor mounting base 7. A weighing connecting frame 4 is fixed to the detection end of the weighing sensor 6, and the wire guide wheel 5 is rotatably mounted on the weighing connecting frame 4. During operation, the servo motor 9 rotates in both directions, driving the horizontal lead screw 11 to rotate in both directions. Since the horizontal slider 8 is limited by the horizontal track 17, when the horizontal lead screw 11 rotates, the horizontal slider 8 slides back and forth along the horizontal track 17, thereby driving the wire guide wheel and the weighing sensor to slide back and forth as a whole, thus moving back and forth axially relative to the winding guide wheel, so as to achieve uniform and flat winding and unwinding of the cut metal wire 19.
[0026] In this embodiment, the weighing signal value detected by the weighing sensor 6 is used to determine whether the guide rollers and motor in the winding module are moving well in coordination with the winding guide roller 16. The weighing sensor 6 is fixed on the sensor mounting base 7, and its detection end is connected to the winding roller 5 through the weighing connecting frame 4. During the winding and unwinding process, the weighing signal detected by the weighing sensor 6 is the resultant force of the gravity of the winding roller 5 and the pressure exerted on the winding roller 5 by the cutting metal wire 19 when it passes through the winding roller 5. Since the gravity of the winding roller 5 is stable, the detected variable is the pressure exerted on the winding roller 5 by the cutting metal wire 19 when it passes through the winding roller 5. Before operation, the machine needs to be debugged to confirm and set a fixed value or a fixed range for the weighing signal. When the signal detected by the weighing sensor 6 is stable within the fixed value or range, it ensures uniform winding and unwinding, and that the winding guide roller 16 is smooth and uniform on its surface.
[0027] If the signal detected by the load cell 6 does not stabilize at the set value during operation, it indicates that the guide wheel or motor in the cable assembly needs adjustment. For example:
[0028] 1. The inconsistent wire feeding speed between the filter wheel 3 and the wire feeding wheel 5 will cause the cutting metal wire 19 to exert too much or too little pressure on the wire feeding wheel 5 when it passes through the wire feeding wheel 5, resulting in the load cell 6's detection signal not being stable within a set value or range.
[0029] 2. The reciprocating lateral movement speed of the linear module corresponding to the wire guide wheel 5 is not matched with the speed of the winding guide wheel 16. This will result in the cutting metal wire 19 between the wire guide wheel 5 and the winding guide wheel 16 being too tight or too loose. This will cause the cutting metal wire 19 to exert too much or too little pressure on the wire guide wheel 5, and consequently, the detection signal of the weighing sensor 6 cannot be stabilized within a fixed value or range.
[0030] Compared to the original distribution of tensioning wheel 2 and winding wheel 5, a filter wheel 3 is installed between tensioning wheel 2 and winding wheel 5 to first filter out any fluctuations in the cut metal wire 19 that may occur during tensioning. Then, a weighing sensor 6 is used for monitoring. By monitoring the combined force of the weight of winding wheel 5 at its position and the pressure exerted by the passing cut metal wire 19, the system determines whether the rotation speed and reciprocating lateral speed of each guide wheel and motor in the current winding device match the rotation of the winding guide wheel 16, and whether it meets the requirements for smooth and uniform winding of the lower winding guide wheel 16. This structure eliminates the need for a sensor with a copper rod detection end, and the cut metal wire 19 does not contact the sensor, thus avoiding wear on the sensor during winding and unwinding. Simultaneously, the monitoring signal is more stable, reasonable, and reliable, ensuring that the winding guide wheel 16 can perform smooth and uniform winding and unwinding operations when the cut metal wire 19 is being wound and unwound using this winding module.
[0031] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
