[0021] In order to solve the problem of reduced cutting accuracy and surface defects caused by the wear of the cutting knife, the present invention adopts a method of real-time monitoring of the cutting knife. When it is detected that the resistance of the cutting knife increases, it indicates that the tool has been worn, and continued use will increase the impact on the structural strength of the corrugated cardboard. At this time, the system will automatically trigger the replacement mechanism: first withdraw the worn tool, and then extend the new spare tool to ensure that the new tool replaces the old tool in time, thereby ensuring the continuity and quality of the cutting process. This not only improves production efficiency, but also significantly improves the quality and structural stability of the finished corrugated cardboard. In this way, the present invention can effectively extend the working life of the cutting equipment, reduce downtime for maintenance, and maintain stable cutting accuracy and product quality.

A tension spring is arranged between the first fixed block 10 and the first cutter 11, and the central axis of the first hydraulic component 9 is not parallel to the edge line of the upper side of the second sliding frame 8.

[0023] In the above scheme, a control terminal is provided at the front side of the workbench 1, and the electrical components in the present invention are all electrically connected to the control terminal on the workbench 1. The moving platform 3 and the driving member 2 can be provided as electric slide rails and electric sliders or electric wheels, all of which are used to enable the moving platform 3 to slide freely on the driving member 2. During use, a control module for controlling the swing of the protective shell 6 can be installed on the fixed seat 5. The first sliding frame 7 can only slide to the rear side. When the corrugated cardboard is cut normally, the second sliding frame 8 is initially located in the middle of the first sliding frame 7, and the first hydraulic component 9 is located in the second sliding frame 7. At the front part in the moving frame 8, the first hydraulic component 9 is installed obliquely, and is used to move the first fixed block 10 backward and upward. When the first cutter 11 cuts the corrugated cardboard normally, the tension spring between the first hydraulic component 9 and the first fixed block 10 is in a stretched state, and the first torsion spring between the first fixed block 10 and the second sliding frame 8 is in a tightened state. When the first cutter 11 is worn, the tension spring on the first hydraulic component 9 causes the lower side extension of the first hydraulic component 9 to drive the first fixed block 10 and the first cutter 11 to move backward and upward, so as to achieve the effect of retracting the first cutter 11.

[0024] Please refer to Figure 6-Figure 8 The monitoring component includes: a second hydraulic component 12 is fixedly connected to the protective shell 6, the front side of the second hydraulic component 12 is an extension part, and the extension part of the second hydraulic component 12 is fixedly connected to the first sliding frame 7; a third hydraulic component 13 is fixedly connected to the second sliding frame 8, the third hydraulic component 13 and the second hydraulic component 12 are fixedly connected and connected with a first connecting pipe, the lower side of the third hydraulic component 13 is an extension part, and the extension part of the third hydraulic component 13 is used to limit the first fixed block 10 and the first cutter 11, and a first spring distance sensor 14 is arranged in the second sliding frame 8. After the position of the second sliding frame 8 changes, the information of the position change of the second sliding frame 8 is transmitted through the first spring distance sensor 14.

[0025] In the above scheme, the second hydraulic component 12 is located at the front part of the second sliding frame 8, and hydraulic oil is stored in the third hydraulic component 13, the first connecting pipe and the second hydraulic component 12. The third hydraulic component 13 is located at the front part of the second sliding frame 8, and the third hydraulic component 13 is located in front of the first hydraulic component 9. The connecting position between the third hydraulic component 13 and the first connecting pipe is located at the lower side of the third hydraulic component 13, which is used to enable the extending part in the third hydraulic component 13 to move upward when the first connecting pipe injects liquid into the third hydraulic component 13. The connecting position between the third hydraulic component 13, the second hydraulic component 12 and the first connecting pipe is located at the rear side of the second hydraulic component 12, which is used to enable the hydraulic oil in the second hydraulic component 12 to enter the first connecting pipe when the extending part in the second hydraulic component 12 moves toward the rear side.

[0026] Please refer to Figure 6-Figure 9The emergency handling component includes: a fourth hydraulic component 15, which is fixedly connected to the second sliding frame 8, a first hydraulic component 9 is located between the fourth hydraulic component 15 and the third hydraulic component 13, the lower side of the fourth hydraulic component 15 is an extension portion, and a second connecting pipe is fixedly connected and communicated between the first hydraulic component 9 and the fourth hydraulic component 15; a second fixed block 16, which is fixedly connected to the second sliding frame 8, a second cutter 17 is rotatably connected to the second fixed block 16, a second torsion spring is arranged between the second cutter 17 and the second fixed block 16, the extension portion of the fourth hydraulic component 15 passes through the second fixed block 16 and is slidably connected thereto, the fourth hydraulic component 15 is used to limit the second cutter 17, a limiting component 18 for limiting the second cutter 17 is fixedly connected to the second sliding frame 8, the rear side of the limiting component 18 is an extension portion, and the extension portion of the limiting component 18 passes through the second fixed block 16 and is slidably connected thereto.

[0027] In the above scheme, hydraulic oil is stored in the first hydraulic component 9, the fourth hydraulic component 15 and the second connecting pipe. The connecting position between the fourth hydraulic component 15 and the second connecting pipe is located at the lower side of the fourth hydraulic component 15, so that when the second connecting pipe injects liquid into the fourth hydraulic component 15, the extending part in the fourth hydraulic component 15 can move upward. The connecting position between the first hydraulic component 9 and the second connecting pipe is located at the upper side of the first hydraulic component 9, so that when the extending part of the first hydraulic component 9 is retracted, the hydraulic oil in the first hydraulic component 9 can enter the second connecting pipe. The second fixed block 16 is located in the middle of the second sliding frame 8. When the corrugated cardboard is cut normally, the second cutting The second torsion spring between the knife 17 and the second fixed block 16 is in a tightened state. The second cutter 17 is provided with two limit holes distributed in upper and lower mirror images. When the second cutter 17 does not swing, the extension of the fourth hydraulic component 15 is inserted into the limit hole on the upper side of the second cutter 17. After the second cutter 17 swings 90°, the extension of the fourth hydraulic component 15 contacts the outer side of the second cutter 17. The limit member 18 is a spring pin. When the second cutter 17 does not swing, the rear side of the limit member 18 contacts the outer side of the second cutter 17. After the second cutter 17 swings 90°, the limit member 18 is inserted into the limit hole on the lower side of the second cutter 17, thereby fixing the state of the second cutter 17.

[0028] Please refer to Figure 6-Figure 8 The first sliding frame 7 is fixedly connected with a fifth hydraulic component 19 and a spring telescopic rod 20. The fifth hydraulic component 19 is fixedly connected to the first hydraulic component 9 and is connected with a third connecting pipe. The telescopic portion of the spring telescopic rod 20 is fixedly connected to the first sliding frame 7. The fifth hydraulic component 19 is used to limit the telescopic portion of the spring telescopic rod 20.

[0029] In the above scheme, a pressure relief valve can be installed in the third connecting pipe to change the triggering sequence of the fifth hydraulic component 19 and the fourth hydraulic component 15. Hydraulic oil is stored in the fifth hydraulic component 19 and the third connecting pipe. The connecting position between the fifth hydraulic component 19 and the third connecting pipe is located at the lower side of the fifth hydraulic component 19, so that when the third connecting pipe injects liquid into the fifth hydraulic component 19, the extending part of the fifth hydraulic component 19 moves upward.

[0030] Working principle: When the device is needed to cut a V-shaped groove on a corrugated cardboard, the staff will first adjust the swing angle of the protective shell 6, thereby adjusting the cutting angle of the first cutter 11 (the adjustment method can be electric or manual).

[0031] After the adjustment of the cutting angle of the first cutter 11 is completed, the staff places the corrugated cardboard on the upper side of the workbench 1, and then the control terminal on the workbench 1 controls the driving member 2 to drive the moving table 3 to move, so that the moving table 3 moves according to the working trajectory. During the movement of the moving table 3, the electric rotating table 4, the fixed seat 5, the protective shell 6, the second hydraulic member 12, the first sliding frame 7, the second sliding frame 8, the first hydraulic member 9 and the first fixed block 10 drive the first cutter 11 to cut the corrugated cardboard (with Figure 5 and Figure 6 Taking the direction of the first cutter 11 as an example, the first cutter 11 moves from right to left during cutting).

[0032] When the first cutter 11 completes cutting of one side of the corrugated cardboard, the control terminal on the workbench 1 controls the electric rotating table 4 to drive the fixed seat 5 and its accessories to rotate 180 degrees, and then the moving table 3 drives the first cutter 11 and its accessories to cut the other side of the corrugated cardboard, thereby cutting a V-shaped groove on the corrugated cardboard. At this point, there will be a V-shaped cardboard on the corrugated cardboard, and this V-shaped cardboard is waste.

[0033] When the resistance exerted by the corrugated cardboard on the first cutter 11 is greater than the supporting force of the spring part on the first spring distance sensor 14 on the first sliding frame 7, the second sliding frame 8, the first hydraulic part 9 and the first fixed block 10 (proving that the first cutter 11 is affected by wear and cannot cut the corrugated cardboard normally), the corrugated cardboard exerts resistance on the first cutter 11, and the first cutter 11 drives the first sliding frame 7 to move backward relative to the corrugated cardboard through the first hydraulic part 9 and the second sliding frame 8. During the movement of the first sliding frame 7 backward, the spring part of the first spring distance sensor 14 and the extended part of the second hydraulic part 12 are squeezed. After the extended part of the second hydraulic part 12 is squeezed, the hydraulic oil in it is transported to the lower side of the third hydraulic part 13 through the first connecting pipe, so that the pressure on the lower side of the third hydraulic part 13 is increased, and the extended part in the third hydraulic part 13 moves upward. During the upward movement of the extended part in the third hydraulic part 13, the limit on the first fixed block 10 and the first cutter 11 is gradually released.

[0034] When the inner extension of the third hydraulic component 13 no longer limits the first fixed block 10 and the first cutter 11, the first fixed block 10 drives the first cutter 11 to move upward to the rear side under the action of the adjacent tension spring, so that the first cutter 11 leaves the working area, ensuring that the worn first cutter 11 is completely pushed out of the cutting position to prevent it from continuing to contact the corrugated cardboard, thereby causing inaccurate cutting or surface defects on the corrugated cardboard, and by moving the first cutter 11 upward to the rear side, it is prevented that the part of the corrugated cardboard that is inaccurately cut or has surface defects interferes with the retraction of the first cutter 11.

[0035] During the process of the first cutter 11 being retracted along with the first fixed block 10, the resistance of the corrugated cardboard to the first cutter 11 has disappeared, and the first sliding frame 7 drives the second sliding frame 8 and its attached parts to move to the state where the first sliding frame 7 is in contact with the second sliding frame 8 (i.e. Figure 7 ), during the resetting process of the first sliding frame 7, the extending part of the second hydraulic component 12 is driven to reset, and the second hydraulic component 12 then extracts the hydraulic oil in the third hydraulic component 13 through the first connecting pipe, so that the extending part of the third hydraulic component 13 is reset] After the extending part of the third hydraulic component 13 is no longer in contact with the first cutter 11, the first cutter 11 swings 90° and then retracts into the second sliding frame 8, thereby hiding the first cutter 11 and preventing accidental injury to the staff during subsequent maintenance.

[0036] During the retraction of the first fixed block 10, the extending portion of the first hydraulic component 9 is retracted, thereby increasing the pressure of the hydraulic oil in the first hydraulic component 9, so that the hydraulic oil enters the lower side of the fourth hydraulic component 15 from the second connecting pipe on the fourth hydraulic component 15 (at this time, the pressure of the hydraulic oil in the first hydraulic component 9 fails to push open the pressure relief valve in the third connecting pipe behind it), so that the extending portion of the fourth hydraulic component 15 moves upward and gradually releases the limit on the second cutter 17, and the second cutter 17 swings forward under the action of the second torsion spring.

[0037] After the second cutter 17 swings 90°, the limiting member 18 is inserted into the second cutter 17 to limit the swing state of the second cutter 17. At this time, the corrugated cardboard is continued to be cut by the second cutter 17 (the knife changing action is completed at that time).

[0038] After the fourth hydraulic component 15 releases the limit on the second cutter 17, the pressure in the fourth hydraulic component 15 no longer increases, and at the same time, the amount of hydraulic oil therein no longer increases. The hydraulic oil in the first hydraulic component 9 immediately breaks through the limit of the pressure relief valve in the third connecting pipe on its rear side, and the hydraulic oil in the first hydraulic component 9 immediately enters the lower side of the fifth hydraulic component 19 through the third connecting pipe, causing the extended part of the fifth hydraulic component 19 to retract, thereby releasing the limit on the telescopic end of the spring telescopic rod 20.

[0039] After the telescopic end of the spring telescopic rod 20 is no longer restricted, the telescopic end of the spring telescopic rod 20 moves the second sliding frame 8 and its attached parts to the front side, so that the second cutter 17 moves from Figure 7 The position of the movable table 3 is moved to the position of the first cutter 11, so that the position of the second cutter 17 is changed without changing the moving distance of the movable table 3.

[0040] After the corrugated cardboard is cut, the staff will replace the worn first cutter 11. After the first cutter 11 is replaced, the staff will manually reset the parts involved in the first cutter 11. The details are as follows: In the first step, the staff pushes the second sliding frame 8 backward to Figure 7 The state in (the telescopic portion of the spring telescopic rod 20 is squeezed during the movement of the second sliding frame 8); In the second step, the staff pulls the limiter 18 forward so that the limiter 18 no longer limits the second cutter 17, and then the staff rotates the second cutter 17 to Figure 7 The state in which the second cutter 17 rotates in the opposite direction by 90° and the second torsion spring is gradually tightened during the rotation of the second cutter 17; In the third step, the staff turns the replaced first cutter 11 by 90° and pulls it and the first fixing block 10 to the front side; In the fourth step, the first fixed block 10 first squeezes the extended portion of the third hydraulic component 13 forward during the process of moving forward (in the process of squeezing the extended portion of the third hydraulic component 13, the hydraulic oil in the second hydraulic component 12 is extracted through the first connecting pipe, so that the extended portion of the second hydraulic component 12 drives the first sliding frame 7 to move backward and squeeze the spring portion of the first spring distance sensor 14); Step 5: After the first fixed block 10 moves to the point where the extended portion of the third hydraulic component 13 is sufficient to insert the first fixed block 10 and the first cutter 11, the staff member no longer controls the movement of the first fixed block 10. At this time, the spring portion of the first spring distance sensor 14 drives the first sliding frame 7 to reset and move. During the movement of the first sliding frame 7, the extended portion of the second hydraulic component 12 is driven to move simultaneously. The second hydraulic component 12 transports the hydraulic oil to the third hydraulic component 13 through the first connecting pipe again, so that the third hydraulic component 13 extends and limits the first fixed block 10 and the first cutter 11. In the sixth step, the tension spring on the extended portion of the first hydraulic component 9 is gradually stretched during the resetting process. During the resetting process of the extended portion of the first hydraulic component 9, the staff opens the pressure relief valve in the third connecting pipe on the rear side thereof, so that the hydraulic oil in the fifth hydraulic component 19 and the fourth hydraulic component 15 flows back to the first hydraulic component 9 through the third connecting pipe and the second connecting pipe respectively. During the reflux of the hydraulic oil in the fifth hydraulic component 19 and the fourth hydraulic component 15, the extended portions in both extend. During the extending process of the extended portions of the fifth hydraulic component 19 and the fourth hydraulic component 15, the limiting of the second cutter 17 and the spring telescopic rod 20 is restored.

[0041] When the corrugated cardboard needs to be cut again, just repeat the above steps.

[0042] Example 2: Based on Example 1, please refer to 10- Fig.12, further comprising: a detection assembly, arranged on the fixed seat 5, for detecting the cut material, the detection assembly comprising: an electric push rod 21, arranged on the side of the fixed seat 5 away from the second sliding frame 8; a limit frame 22, fixedly connected to the telescopic end of the electric push rod 21, a sliding block 23 is slidably connected in the limit frame 22, and an elastic member for driving the sliding block 23 to reset is arranged in the limit frame 22; a fixed cylinder 24, fixedly connected to the sliding block 23, a probe rod 25 is slidably connected to the fixed cylinder 24, two limit rings 26 are fixedly connected in the fixed cylinder 24, and the two limit rings 26 are It is used to limit the position of the probe rod 25. A second spring distance sensor 27 is arranged in the fixing tube 24. When the load of the probe rod 25 changes, the information of the weight change of the probe rod 25 is transmitted through the second spring distance sensor 27. An L-shaped frame 28 is fixedly connected to the side of the fixing seat 5 close to the electric push rod 21. When the probe rod 25 is reset, the L-shaped frame 28 shields the lower side of the probe rod 25 to prevent the probe rod 25 from excessively tearing the material. The lower side of the probe rod 25 is located on the upper side of the lower side of the L-shaped frame 28 or the lower sides of the two are located on the same vertical plane, which is used to reset the probe rod 25 to Fig.11 When in the state of middle, the probe rod 25 is no longer in contact with the V-shaped paperboard.

[0043] In the above scheme, the electric push rod 21 is located at the rear side of the fixed seat 5. When cutting a V-shaped groove on the corrugated cardboard, the central axis of the telescopic end of the electric push rod 21 needs to be located on the same vertical line as the lower side of the first cutter 11. The elastic member in the limit frame 22 is a spring, and the L-shaped frame 28 is located at the lower rear part of the fixed seat 5.

[0044] Working principle: In order to verify the cutting accuracy and ensure the integrity of the cutting, the present invention simulates the action of the insertion rod when being inserted into and pulled out of the soil, so that the insertion rod is intermittently inserted into the cut V-shaped cardboard, and through the resistance when the insertion rod is pulled out, it is identified whether the V-shaped groove is completely cut. For details, please refer to the following: When it is necessary to detect the V-shaped cardboard cut from the corrugated cardboard, the control terminal on the workbench 1 controls the telescopic end of the electric push rod 21 to extend, and the telescopic end of the electric push rod 21 pushes the limit frame 22 downward, so that the limit frame 22 drives the sliding block 23 and the fixed cylinder 24 to move downward, and the fixed cylinder 24 squeezes the probe rod 25 downward through the limit ring 26 on its inner upper side.

[0045] When the probe rod 25 is inserted into the V-shaped cardboard cut out of the corrugated cardboard, the probe rod 25, the fixed cylinder 24, and the sliding block 23 slide along the limit frame 22 (the elastic member is squeezed during the movement of the sliding block 23, and the state at this time is: the probe rod 25 and the corrugated cardboard remain stationary, and the limit frame 22 slides). Then, the control terminal on the workbench 1 controls the telescopic end of the electric push rod 21 to retract, and the telescopic end of the electric push rod 21 drives the fixed cylinder 24 to reset and slide through the limit frame 22 and the sliding block 23. Since the upper side of the probe rod 25 is only in contact with the adjacent limit ring 26 at this time, the fixed cylinder 24 will not directly drive the probe rod 25 to move upward through the upper limit ring 26 during the upward movement. Therefore, the fixed cylinder 24 will drive the probe rod 25 to reset and move through the second spring distance sensor 27 during the upward movement, so that the probe rod 25 can move upward. The V-shaped paperboard moves upward until the probe rod 25 moves to the same horizontal plane as the lower side thereof and the L-shaped frame 28, and the V-shaped paperboard is disengaged from the probe rod 25. After the probe rod 25 is no longer in contact with the V-shaped paperboard cut out of the corrugated paperboard, the elastic member on the sliding block 23 drives it and the attached parts to slide and reset. When the V-shaped paperboard is not disengaged from the corrugated paperboard, when the fixing cylinder 24 pulls the probe rod 25 to move through the spring portion of the second spring distance sensor 27 during the upward movement, the V-shaped paperboard will exert an upward resistance on the probe rod 25. At that time, the spring portion of the second spring distance sensor 27 will be stretched, thereby determining whether the V-shaped paperboard is disengaged from the corrugated paperboard. When the second spring distance sensor 27 moves upward until the spring portion is sufficient to force the probe rod 25 to pull upward, the above-mentioned process of resetting the probe rod 25 can be repeated.

[0046] When the spring portion of the second spring distance measuring sensor 27 is stretched, the V-shaped cardboard cut out of the corrugated cardboard has exerted resistance on the probe rod 25, and the probe rod 25 has stretched the spring portion of the second spring distance measuring sensor 27. At this time, the second spring distance measuring sensor 27 transmits an electrical signal to the control terminal on the workbench 1 so that the staff can know the cutting situation in time.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
