Description

Technical Field

[0001] The invention belongs to the technical field of wire cutters, and in particular relates to a wire cutter and a method for measuring and controlling the position of a grinding wheel of the wire cutter. Background Art

[0002] Tobacco shredding is an important process in the tobacco processing technology, and the shredder is the main equipment in the tobacco processing process. At present, slim cigarettes are becoming more and more popular in the market, and the shredding process has also been adjusted accordingly, requiring the shredder to complete the function of fixed-length shredding. The shredder grinding system is the working carrier of the shredder grinding wheel, which is used to grind the blade of the shredder to form a toothed knife. The system integrates a grinding wheel feeding device and a grinding wheel reciprocating motion device. The positioning accuracy of the grinding wheel reciprocating motion device for the grinding wheel directly determines the cutting accuracy of the toothed knife in the lateral position, which in turn affects the accuracy of the length of tobacco cut by the shredder and the quality of shredded tobacco. Controlling the grinding wheel feeding position requires accurate positioning of the real-time position of the shredder grinding wheel, and timely detection and adjustment when errors occur in the grinding wheel position to reduce the losses caused by the errors. During the transmission process of the shredder blade sharpening system, in addition to the detection error caused by damage to the detection element, abnormalities in the intermediate transmission mechanism will also cause grinding wheel position errors. This error will cause the distance between the toothed knife grooves ground by the shredder blade when the shredder blade is grinding. Ultimately, the tobacco cut by the shredder blade will be of different lengths, which is not conducive to the rolling of slim cigarettes.

[0003] In view of this, the present invention is proposed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a wire cutter and a method for measuring and controlling the position of the grinding wheel of the wire cutter. The real-time position of the grinding wheel is detected by setting two detection components, and the two real-time detection results are compared. When the real-time detection results are found to be inconsistent, the correction module sends a signal to the control unit, and the driving component returns the grinding wheel to the preset initial position under the control of the control unit, thereby realizing real-time detection of the grinding wheel position and being able to immediately correct the error of the grinding wheel position when an error occurs, so as to avoid the grinding wheel grinding out a toothed knife with different groove spacing.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a slicing machine, comprising:

[0006] A driving component drives the grinding wheel to move from a current position to a preset direction;

[0007] A first detection component, used for detecting a first position of the grinding wheel;

[0008] A second detection component, used for detecting a second position of the grinding wheel;

[0009] A processing module, used for determining whether the first position and the second position are the same position;

[0010] The correction module is connected to the processing module and is used for correcting the grinding wheel to a preset initial position when the first position and the second position are not the same position.

[0011] Furthermore, the wire cutting machine also includes a control unit connected to the correction module and the driving component. The correction module transmits information that the first position and the second position are not the same position to the control unit. The control unit controls the driving component to operate and drives the grinding wheel to move in the opposite direction and return to a preset initial position.

[0012] Furthermore, the correction module further comprises a proximity switch, and the proximity switch is arranged at a preset initial position of the grinding wheel;

[0013] The proximity switch has two working states:

[0014] In the first working state, the grinding wheel is located at a preset initial position;

[0015] In the second working state, the grinding wheel is separated from the preset initial position.

[0016] Further, when the grinding wheel moves to a preset initial position, the proximity switch is in a first working state, and the control unit controls the driving component to stop working;

[0017] When the grinding wheel leaves the preset initial position, the proximity switch is in the second working state, and the control unit controls the driving component to drive the grinding wheel to move.

[0018] Furthermore, the shredder also includes:

[0019] A grinding wheel support assembly connected to the grinding wheel;

[0020] The intermediate transmission mechanism has one end connected to the driving component and the other end connected to the grinding wheel support assembly, and is used for transmitting the driving force of the driving component to drive the grinding wheel support assembly to move.

[0021] Further, the grinding wheel support assembly moves to contact the proximity switch, and the proximity switch switches to a first working state.

[0022] The present invention also provides a method for measuring and controlling the position of a grinding wheel of a wire cutter, which is applied to the wire cutter as described above.

[0023] The wire cutting machine grinding wheel position measurement and control method comprises:

[0024] S1: Control the driving component to drive the grinding wheel to move from a first current position to a preset direction;

[0025] S2: Acquire a first position of a grinding wheel detected by a first detection component;

[0026] S3: Acquire a second position of the grinding wheel detected by the second detection component;

[0027] S4: Determine whether the first position and the second position are the same position, if yes, execute step S5, if no, execute step S6;

[0028] S5: controlling the driving component to drive the grinding wheel to move from the second current position to a preset direction;

[0029] S6: Calibrate the grinding wheel to the preset initial position.

[0030] Further, in step S6, calibrating the grinding wheel to a preset initial position includes:

[0031] S7: driving the grinding wheel to move in the opposite direction of the preset direction;

[0032] S8: Detect whether the grinding wheel support assembly is in contact with the proximity switch.

[0033] Further, in step S6, calibrating the grinding wheel to a preset initial position also includes:

[0034] S9: Record the number of times the grinding wheel support assembly contacts the proximity switch;

[0035] S10: determining whether the number of times the grinding wheel support assembly contacts the proximity switch is greater than or equal to a preset number;

[0036] S11: Issue a warning message.

[0037] Furthermore, in step S11, after the warning information is issued, the control unit controls the driving component to stop working, and the grinding wheel stops at a preset initial position.

[0038] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0039] 1. A wire cutter and a method for measuring and controlling the position of a grinding wheel for a wire cutter provided by the present invention detect the real-time position of the grinding wheel by setting two detection components and compare the two real-time detection results to ensure the accuracy of the detection of the grinding wheel position and avoid the wire cutter sharpening system or the wire cutter operator being unable to detect the detection error when the detection component has a detection error, resulting in a grinding error of the grinding wheel on the wire cutter blade.

[0040] 2. The present invention provides a wire cutting machine and a method for measuring and controlling the position of the grinding wheel of the wire cutting machine. When the comparison shows that two real-time detection results are inconsistent, the correction module sends a signal to the control unit, and the driving component returns the grinding wheel to a preset initial position under the control of the control unit, so that the lateral movement of the grinding wheel can be stopped immediately when an error occurs, and the position of the grinding wheel is corrected once or multiple times to prevent the grinding wheel from grinding a toothed knife with a grinding error.

[0041] 3. The present invention provides a wire cutter and a method for measuring and controlling the grinding wheel position of the wire cutter. When the number of contacts between the grinding wheel support assembly and the proximity switch reaches a preset number, the wire cutter can issue an early warning message to prompt the operator that the wire cutter needs to be repaired to eliminate the grinding wheel position error caused by the intermediate transmission mechanism.

[0042] 4. The wire cutter and wire cutter grinding wheel position measurement and control method provided by the present invention are simple and practical, can detect the position error of the grinding wheel in advance, and automatically correct the error or prompt manual work and maintenance, thereby reducing the error rate of the wire cutter blade when grinding into a toothed knife, and has good economic benefits and application prospects.

DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0052] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0053] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] At present, slim cigarettes are becoming more and more popular among consumers in China, and slim cigarettes need to be rolled with fixed-length tobacco. For controlling the length of tobacco, a fixed-length shredding method is generally used. Fixed-length shredding generally uses a toothed knife to cut the tobacco raw material. In the process of grinding the toothed knife with a grinding wheel, the precise positioning of the grinding wheel is the key to grinding a qualified toothed knife. Usually, the positioning of the grinding wheel is achieved by installing a detection device on the shredder. Although the detection device can directly detect or indirectly detect the position of the grinding wheel by detecting the motion parameters of the driving device, the transmission mechanism may generate a transmission error during the movement. At this time, the detection device will not be able to detect the generated transmission error and will feedback erroneous position data to the operator, which will cause the shredder blade to cut tobacco of different lengths after being ground, which is not conducive to the rolling of slim cigarettes and is likely to cause economic losses.

[0055] In order to solve this problem, the present invention designs a wire cutter and a wire cutter grinding wheel position measurement and control method, by setting two detection components to detect the real-time position of the grinding wheel, and can obtain two real-time detection results. When it is found that the real-time detection results are inconsistent, the correction module sends a signal to the control unit, and the control unit adjusts the driving component, and the driving component returns the grinding wheel to the preset initial position, corrects the position error of the grinding wheel, and avoids the grinding wheel grinding a toothed knife with different groove spacing. The details are as follows:

[0056] like Figure 1 As shown, the present invention provides a wire cutting machine, including: a driving component 1, a first detection component 2, a second detection component 3, an intermediate transmission mechanism 4, a grinding wheel support component 5, a grinding wheel 6, a proximity switch 7, a linear guide rail 8, and a frame 9. The first detection component 2 is connected to the driving component 1; one end of the intermediate transmission mechanism 4 is connected to the driving component 1, and the other end is connected to the grinding wheel support component 5; the intermediate transmission mechanism 4 includes: a gearbox 41, a coupling 42, a ball screw 43 and a connecting member 44, the driving component 1 is connected to one end of the coupling 42 through the gearbox 41, and the other end of the coupling 42 is connected to the ball screw 43; one end of the connecting member 44 is connected to the screw nut on the ball screw 43, and the other end is connected to the grinding wheel support component 5; the grinding wheel support component 5 is slidably connected to the linear guide 8, and the linear guide 8 is fixed on the frame 9; the grinding wheel 6 is rotatably connected to the grinding wheel support component 5; the proximity switch 7 is arranged at one end of the linear guide 8 close to the preset initial position of the grinding wheel 6; the second detection component 3 is fixed on the frame 9.

[0057] Preferably, the driving component 1 adopts a servo motor, so that when the driving component 1 needs to stop working, the driving component 1 can stop working immediately to prevent the driving component 1 from continuing to drive the grinding wheel 6 to move along the preset direction under the action of inertia.

[0058] Preferably, both the first detection component 2 and the second detection component 3 use absolute encoders, which is beneficial to improving the detection accuracy and timely discovering the position error of the grinding wheel 6.

[0059] The shredder provided by the present invention also includes a processing module, a correction module and a control unit.

[0060] The processing module is connected to the first detection component 2 and the second detection component 3, receives the first position information detected by the first detection component 2 and the second position information detected by the second detection component 3, and compares the two pieces of position information to determine whether the first position and the second position of the grinding wheel 6 are the same position.

[0061] Preferably, the first position detected by the first detection component 2 and the second position detected by the second detection component 3 are the real-time positions of the grinding wheel 6, which are used to determine in real time whether the first position and the second position of the grinding wheel 6 are the same position, which is conducive to discovering the position error of the grinding wheel 6 in advance.

[0062] The processing module is connected to the control unit, and the control unit can control the working state of the driving component 1 according to the result of "whether the first position and the second position of the grinding wheel 6 are the same position" determined by the processing module.

[0063] If the first position and the second position of the grinding wheel 6 detected are the same, it means that the position of the grinding wheel 6 is correct at this time. Under the control of the control unit, the driving component 1 will drive the grinding wheel to continue to maintain the current motion state, that is, to keep moving laterally along the linear guide rail 8;

[0064] If the detected first position and second position of the grinding wheel 6 are not the same position, it means that the position of the grinding wheel 6 begins to have errors. Under the control of the control unit, the driving component 1 will stop working, so that the grinding wheel 6 stops moving laterally along the linear guide rail 8.

[0065] In addition, when the processing module determines that the first position and the second position are not the same position, the processing module transmits the judgment information that "the first position and the second position are not the same position" to the correction module, and the correction module corrects the grinding wheel 6 to the preset initial position: the correction module transmits the information that "the first position and the second position are not the same position" to the control unit, and the control unit controls the driving component 1 to work, driving the grinding wheel 6 to move in the opposite direction and return to the preset initial position.

[0066] When the grinding wheel 6 returns to the preset initial position in the reverse direction, the grinding wheel support assembly 5 connected to the grinding wheel 6 moves along the linear guide rail 8 toward the preset initial position of the grinding wheel 6 until the grinding wheel 6 reaches the preset initial position.

[0067] The calibration module further comprises a proximity switch 7, which is arranged at a preset initial position of the grinding wheel 6; the proximity switch 7 can contact the grinding wheel support assembly 5, and the proximity switch 7 has two working states:

[0068] When the grinding wheel support assembly 5 is in contact with the proximity switch 7, the proximity switch 7 is in the first working state, and the correction module transmits the information of "the proximity switch 7 is in the first working state" to the control unit, and the control unit controls the driving component 1 to stop working. At this time, the grinding wheel 6 is located at the preset initial position;

[0069] After the grinding wheel 6 has been at the preset initial position for a preset time, the control unit controls the driving component 1 to operate, so that the grinding wheel 6 leaves the preset initial position and moves in a preset direction, and the grinding wheel support assembly 5 is out of contact with the proximity switch 7.

[0070] When the grinding wheel support assembly 5 is out of contact with the proximity switch 7, the proximity switch 7 is in the second working state, and the correction module transmits the information "the proximity switch 7 is in the second working state" to the control unit. The control unit controls the driving component 1 to maintain the current working state, and the driving component 1 drives the grinding wheel 6 to move along the preset direction.

[0071] In the above scheme, the proximity switch 7 can adopt a variety of switch forms, such as a contact switch, a reed switch, a photoelectric switch, etc. If the proximity switch 7 adopts a contact switch, then when the grinding wheel support assembly 5 contacts the proximity switch 7, the proximity switch 7 is converted to the first working state; if the proximity switch 7 adopts a reed switch, it is necessary to set a permanent magnet or an electromagnetic coil on the side of the grinding wheel support assembly 5 close to the proximity switch 7. When the grinding wheel support assembly 5 is in contact with the proximity switch 7, the magnetic field generated by the permanent magnet or the energized electromagnetic coil can close the reed switch, and the proximity switch 7 is converted to the first working state; if the proximity switch 7 adopts a photoelectric switch, then when the grinding wheel support assembly 5 or the grinding wheel 6 blocks or reflects the light beam emitted by the photoelectric switch, the photoelectric switch is actuated, and the proximity switch 7 is converted to the first working state.

[0072] As an implementation scheme, Figure 2 As shown, the present invention provides a method for measuring and controlling the position of a grinding wheel of a wire cutting machine, comprising the following steps:

[0073] S1: Start the shredder;

[0074] S2: Switch the working state of the wire cutter blade to the grinding state;

[0075] S3: controlling the driving component to drive the grinding wheel to move from the first current position to a preset direction;

[0076] S4: Acquire a first position of the grinding wheel detected by the first detection component;

[0077] S5: Acquire a second position of the grinding wheel detected by the second detection component;

[0078] S6: Determine whether the first position and the second position are the same position, if yes, execute step S7, if no, execute step S8;

[0079] S7: Control the driving component to drive the grinding wheel to move from the second current position to a preset direction;

[0080] S8: driving the grinding wheel to move in the opposite direction of the preset direction;

[0081] S9: Detect whether the grinding wheel support assembly is in contact with the proximity switch.

[0082] The above scheme is used to determine whether there is a position error in the position of the grinding wheel. If there is no position error in the grinding wheel, the current motion state of the grinding wheel is maintained; if there is a position error in the grinding wheel, the grinding wheel needs to be corrected to the preset initial position, that is, the driving component drives the grinding wheel to move in the opposite direction of the preset direction until the grinding wheel support assembly contacts the proximity switch, the driving component stops working, and the grinding wheel stops at the preset initial position.

[0083] In step S2, according to the different installation methods and installation positions of the shredder blade, the working state of the shredder blade needs to be adjusted to the state to be ground. If the blade is installed on a knife roller, the knife roller needs to keep rotating when the grinding wheel grinds the blade; if the blade is installed on the clamping mechanism of the shredder, the shredder blade performs linear reciprocating motion to cut the material, and the grinding wheel grinds the blade, the shredder blade needs to be suspended, and the position of the shredder blade relative to the grinding wheel should remain unchanged, and the shredder blade is in the state to be ground, so that the grinding wheel can grind the blade to form a toothed knife.

[0084] In step S3, under the control of the control unit, the driving component drives the grinding wheel to move from a first current position to a preset direction. The first current position is the position of the grinding wheel before being driven by the driving component, that is, the first current position can be a preset initial position of the grinding wheel, or it can be any position other than the preset initial position, so that the grinding wheel can grind the wire cutter blade from any position of its travel.

[0085] In step S4, the first detection component is connected to the driving component. The first detection component calculates the first position of the grinding wheel by detecting and recording the rotation speed, rotation time and other motion parameters of the driving component, and according to the relevant coefficients such as the transmission ratio of the intermediate transmission mechanism. In the calculation process of the first position, it is assumed that there is no transmission error in the intermediate transmission mechanism, so as to compare with the second position detected by the second detection component to determine whether there is a transmission error in the intermediate transmission mechanism.

[0086] In step S5, the second detection component obtains the second position of the grinding wheel by directly detecting the distance the grinding wheel moves along the preset direction. The second position includes the distance the grinding wheel moves along the preset direction, and the acquisition of the second position is not affected by the intermediate transmission mechanism. That is to say, even if there is a transmission error in the intermediate transmission mechanism, the information in the second position does not include this transmission error.

[0087] In step S6, the first position is compared with the second position, and in the processing module, the received information of the first position and the second position are converted into the same information format and displayed on the control panel of the wire cutter or the operator's smart device, so that the operator can check the position detection information of the grinding wheel at any time, providing reference material for the operator's production work.

[0088] In step S7, when it is determined that the first position and the second position are the same position, the driving component maintains the current motion state unchanged and continues to drive the grinding wheel to move from the second current position to the preset direction; in the preset direction of the grinding wheel movement, the second current position is located after the first current position, that is, the grinding wheel moves along the preset direction, the grinding wheel starts from the first current position and then reaches the second current position; and the detection of the grinding wheel position is real-time, that is, the processing module determines in real time whether the first position and the second position are the same position. Although the first current position and the second current position are two different positions, the two positions can be infinitely close, so as to timely discover the position error of the grinding wheel.

[0089] In step S8, when it is determined that the first position and the second position are not the same position, the processing module transmits the information that "the first position and the second position are not the same position" to the correction module, and the correction module then transmits the information that "the first position and the second position are not the same position" to the control unit, and the control unit immediately controls the driving component to stop working, and the grinding wheel stops moving at the second current position. Subsequently, the correction module sends a signal to the control unit to retract the grinding wheel, and the control unit controls the driving component to drive the grinding wheel to move in the opposite direction of the preset direction, so as to retract the grinding wheel to the preset initial position and correct the position error of the grinding wheel. The second current position is the position when it is determined that the grinding wheel begins to have a position error. Immediately stopping the movement of the grinding wheel in the preset direction at the second current position can avoid the grinding wheel from continuing to move and grinding the shredder blade to the greatest extent, resulting in the shredder blade being over-ground.

[0090] In step S9, when the grinding wheel support assembly is not in contact with the proximity switch, the proximity switch maintains the second working state, and the control unit controls the driving component to move the grinding wheel in the opposite direction of the preset direction until the grinding wheel support assembly contacts the proximity switch, and the proximity switch switches from the second working state to the first working state. This switching of working states can directly indicate that the grinding wheel support assembly contacts the proximity switch, and there is no need to set up a judgment module to judge whether the grinding wheel support assembly contacts the proximity switch. When the grinding wheel support assembly contacts the proximity switch, the correction module sends a signal to the control unit that the grinding wheel has reached the preset initial position, and the control unit immediately controls the driving component to stop working. At this time, the grinding wheel stops at the preset initial position, and the position correction of the grinding wheel is completed.

[0091] When the grinding wheel stops at the preset initial position, the first detection component connected to the driving component and the second detection component that directly detects the grinding wheel position perform data zeroing, so that when the grinding wheel moves again along the preset direction, the real-time position of the grinding wheel can be detected.

[0092] As an implementation scheme, Figure 3 As shown, the present invention provides a method for measuring and controlling the position of a grinding wheel of a wire cutting machine, which also includes the following steps:

[0093] S1: Start the shredder;

[0094] S2: Switch the working state of the wire cutter blade to the grinding state;

[0095] S3: controlling the driving component to drive the grinding wheel to move from the first current position to a preset direction;

[0096] S4: Acquire a first position of the grinding wheel detected by the first detection component;

[0097] S5: Acquire a second position of the grinding wheel detected by the second detection component;

[0098] S6: Determine whether the first position and the second position are the same position, if yes, execute step S7, if no, execute step S8;

[0099] S7: Control the driving component to drive the grinding wheel to move from the second current position to a preset direction;

[0100] S8: driving the grinding wheel to move in the opposite direction of the preset direction;

[0101] S9: Detect whether the grinding wheel support assembly is in contact with the proximity switch;

[0102] S10: Control the driving component to drive the grinding wheel to move from a preset initial position to a preset direction;

[0103] S11: Acquire the first position and the second position of the grinding wheel;

[0104] S12: Determine whether the first position and the second position are the same position, if yes, execute step S13, if no, execute step S14;

[0105] S13: controlling the driving component to drive the grinding wheel to move from the third current position to a preset direction;

[0106] S14: controlling the driving component to drive the grinding wheel to move from the third current position in the opposite direction of the preset direction;

[0107] S15: Detecting whether the grinding wheel support assembly is in contact with the proximity switch;

[0108] S16: Return to step S10, obtain the first position and the second position of the grinding wheel, until it is determined that the first position and the second position are the same position;

[0109] S17: Control the driving component to drive the grinding wheel to move from the Nth current position to a preset direction.

[0110] In the above scheme, steps S10 to S17 are used to verify whether the previous correction of the grinding wheel position is accurate. If the correction is accurate, the control unit controls the driving component to drive the grinding wheel to continue to move in the preset direction until the grinding wheel has a position error again or the grinding wheel completes the grinding work; if the correction is inaccurate, the position of the grinding wheel needs to be corrected again, and the control unit controls the driving component to drive the grinding wheel to move in the opposite direction of the preset direction, and the grinding wheel returns to the preset initial position. Repeat the above process, and finally after N-1 times of automatic correction process, the influence of the installation position and sensitivity of the proximity switch on the grinding wheel positioning is eliminated, and the position of the grinding wheel no longer has errors. At this time, grinding the blade of the wire cutter can avoid the negative impact of the grinding wheel position error on the grinding positioning accuracy and grinding quality.

[0111] In step S13, when the grinding wheel is located at the third current position and the detected first position and the second position are the same position, the control unit controls the driving component to drive the grinding wheel to continue to move from the third current position to the preset direction.

[0112] In step S14, when the grinding wheel is located at the third current position and the detected first position and the second position are not the same position, the control unit controls the driving component to drive the grinding wheel to move from the third current position in the opposite direction of the preset direction.

[0113] In step S16, after the grinding wheel returns to the preset initial position, return to step S10, and obtain the first position and the second position of the grinding wheel, until it is determined that the first position is the same as the second position, that is, the grinding wheel no longer has a position error, and then execute step S17, and the control unit controls the driving component to drive the grinding wheel to move from the Nth current position to the preset direction.

[0114] The Nth current position means the real-time position of the grinding wheel when the grinding wheel, which has been calibrated N-1 times, moves along a preset direction and the first detection component and the second detection component respectively obtain the first position and the second position.

[0115] As an implementation scheme, Figure 4 As shown, the present invention provides a method for measuring and controlling the position of a grinding wheel of a wire cutting machine, which also includes the following steps:

[0116] S1: Start the shredder;

[0117] S2: Switch the working state of the wire cutter blade to the grinding state;

[0118] S3: controlling the driving component to drive the grinding wheel to move from the first current position to a preset direction;

[0119] S4: Acquire a first position of the grinding wheel detected by the first detection component;

[0120] S5: Acquire a second position of the grinding wheel detected by the second detection component;

[0121] S6: Determine whether the first position and the second position are the same position, if yes, execute step S7, if no, execute step S8;

[0122] S7: Control the driving component to drive the grinding wheel to move from the second current position to a preset direction;

[0123] S8: driving the grinding wheel to move in the opposite direction of the preset direction;

[0124] S9: Detect whether the grinding wheel support assembly is in contact with the proximity switch;

[0125] S10: Control the driving component to drive the grinding wheel to move from a preset initial position to a preset direction;

[0126] S11: Acquire the first position and the second position of the grinding wheel;

[0127] S12: Determine whether the first position and the second position are the same position, if yes, execute step S13, if no, execute step S14;

[0128] S13: controlling the driving component to drive the grinding wheel to move from the third current position to a preset direction;

[0129] S14: controlling the driving component to drive the grinding wheel to move from the third current position in the opposite direction of the preset direction;

[0130] S15: Detecting whether the grinding wheel support assembly is in contact with the proximity switch;

[0131] S16: Return to step S10, and record the number of times the grinding wheel support assembly contacts the proximity switch;

[0132] S17: determining whether the number of times the grinding wheel support assembly contacts the proximity switch is greater than or equal to a preset number;

[0133] S18: Issue a warning message.

[0134] The above scheme is used to monitor the number of corrections of the grinding wheel position after the grinding wheel completes the correction process. When the number of corrections reaches the preset number, the wire cutter will issue a warning message, indicating that the position of the grinding wheel of the wire cutter can no longer be corrected by the correction method of "the grinding wheel returns to the preset initial position". Maintenance personnel are required to inspect the intermediate transmission mechanism, detection components, etc. to eliminate the position error of the grinding wheel during the transmission process.

[0135] In step S16, one contact between the proximity switch and the grinding wheel support assembly indicates that the grinding wheel has undergone a position correction. The number of contacts between the proximity switch and the grinding wheel support assembly is recorded, that is, the number of times the grinding wheel has undergone position correction is recorded, so as to facilitate statistics on the number of position corrections of the grinding wheel and compare it with the preset number.

[0136] In step S17, when it is determined that the number of times the grinding wheel support assembly contacts the proximity switch is less than the preset number, it means that the position error of the grinding wheel during movement can be eliminated by performing position correction on the grinding wheel; when it is determined that the number of times the grinding wheel support assembly contacts the proximity switch is greater than or equal to the preset number, it means that the position error of the grinding wheel mainly comes from the intermediate transmission mechanism, and the transmission error generated by the intermediate transmission mechanism during the transmission process cannot be eliminated by performing position correction on the grinding wheel, and maintenance personnel are required to inspect the intermediate transmission mechanism to eliminate the transmission error.

[0137] In step S18, the early warning information issued by the wire cutter includes text information, in which the number of times the grinding wheel is calibrated, the current position information of the grinding wheel when each calibration is started, the time nodes of different working states of the driving components, etc. are recorded, and displayed on the control panel of the wire cutter or the screen of the operator's smart device for easy reference; the early warning information also includes sound information, which prompts the operator through a buzzer or loudspeaker that the wire cutter needs to be inspected.
