Description

Technical Field

[0001] The invention relates to the field of digital die-cutting machines, in particular to an automatic knife-setting mechanism for digital die-cutting machines. Background Art

[0002] Digital die-cutting machine is an advanced and efficient automated production equipment. It belongs to the category of digital printing equipment. It cuts materials through digital control and achieves graphic design and decoration effects.

[0003] When using a digital die-cutting machine to cut label paper, since the sizes of label papers to be processed are different, in order to facilitate the cutting of label papers of different sizes, the cutting heads in the die-cutting unit of the digital die-cutting machine need to be adjusted in position. However, there are a large number of cutting heads in the die-cutting unit. Manually adjusting them one by one takes more time, which affects the cutting efficiency of the digital die-cutting machine for label paper. Therefore, an automatic tool alignment mechanism is set on the digital die-cutting machine to automatically adjust the positions of multiple cutting heads.

[0004] When the existing automatic knife-aligning mechanism is in use, the cutting head repeatedly and quickly cuts on the label paper. The friction between the cutting head and the label paper slowly increases after long-term use, which not only causes the cutting edge of the label paper to be gradually worn away, reducing the quality of the finished product, but also causes damage to the cutting head itself. For example, the smoothness of the cutting head gradually increases, making it more likely to produce burrs and unevenness during the cutting process, thereby affecting the processing quality of the label paper.

[0005] Therefore, we propose an automatic tool setting mechanism for a digital die-cutting machine to solve the above problems. Summary of the invention

[0021] The technical scheme of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 10As shown, an automatic tool setting mechanism for a digital die-cutting machine includes a frame 1, a Y-axis servo motor 2 is fixedly installed at one end of the frame 1, one end of the output shaft of the Y-axis servo motor 2 is fixedly connected to a Y-axis lead screw 3 through a coupling, one end of the Y-axis lead screw 3 extends to the inside of the frame 1, a Y-axis slider 4 is slidably connected to one side of the outer surface of the frame 1, one end of the back side of the Y-axis slider 4 is threadedly connected to the Y-axis lead screw 3 through a threaded block, an immersion cleaning mechanism 5 is installed at the bottom of one side of the Y-axis slider 4, a tension adjustment component 18 is fixedly installed at one side of the bottom of the immersion cleaning mechanism 5, and a scraping component 6 is slidably connected to the inside of the immersion cleaning mechanism 5; The scraping assembly 6 includes a connecting sleeve 61, a screw hole 62 is opened in the middle of the connecting sleeve 61, a spring 63 is fixedly installed on one side of the bottom of the connecting sleeve 61, a connecting plate 64 is fixedly installed on the bottom end of the spring 63, the top of the connecting plate 64 is rotatably connected to a first screw rod 65, the top of the first screw rod 65 passes through the screw hole 62 and extends to the top of the connecting sleeve 61, the top of the first screw rod 65 is fixedly connected to a pressure plate 66, and cleaning brushes 67 are fixedly installed on the tops of both sides of the pressure plate 66, and the two cleaning brushes 67 have different lengths.

[0023] It should be noted that the frame 1 is installed on the digital die-cutting machine. When the label paper is cut, the label paper passes between the knife assembly 16 and the X-axis assembly on the frame 1 and is cut by the cutting head in the knife assembly 16. The Y-axis servo motor 2 is connected to the external power supply through the power cord. The Y-axis lead screw 3 extends into the frame 1, and the end is connected to the inner wall of the frame 1 by a bearing. The surface of the Y-axis lead screw is provided with a thread. Driven by the Y-axis servo motor 2, the Y-axis slider 4 can be driven to move so that the position of the knife assembly 16 is aligned with the position of the label paper. Slide rails are installed on the upper and lower sides of the outer surface of the frame 1 and on the back of the Y-axis slider 4. The slider on the back of the Y-axis slider 4 cooperates with the slide rails to ensure that the position of the Y-axis slider 4 is more stable. The immersion cleaning mechanism 5 is installed at the bottom of the side of the Y-axis slider 4 by screws, which does not affect the assembly between the tool setting component 16 and the Y-axis slider 4, and does not delay the subsequent up and down movement of the tool setting component 16 on the Y-axis slider 4. When the Y-axis servo motor 2 drives the Y-axis slider 4 to move along the frame 1 through the Y-axis lead screw 3, the position of the immersion cleaning mechanism 5 will not be affected. Multiple scraping components 6 are arranged in the immersion cleaning mechanism 5. When the automatic tool setting mechanism adjusts each cutting head to move, it can also drive each scraping component 6 to move therewith, ensuring that when each cutting head moves into the immersion cleaning mechanism 5 for cleaning and cooling the head, it can move downward from the scraping component 6 and use the scraping component 6 to scrape the cutting head to remove excess cutting The cutting fluid is cleaned up, the two ends of the connecting sleeve 61 are sleeved between the two limit rods 54, the screw hole 62 is adapted to the first screw 65, the spring 63 is a tension spring with good elasticity, the top end of which is stuck at the bottom of the connecting sleeve 61, and the bottom end is stuck together with the connecting plate 64, the bottom end of the first screw 65 is rotatably connected with the connecting plate 64, and after the upper pressure plate 66 is pressed by the upper cutting head, the first screw 65 can be rotated downward, and when the first screw 65 is rotated downward, the two cleaning brushes 67 on both sides of the top of the pressure plate 66 can contact the cutting head, and then when the cutting head moves upward, the spring 63 loses pressure, and the first screw 65 can be rotated upward, so that the cleaning brush 67 rotates to scrape off the excess cutting fluid on the surface of the cutting head; The tension adjustment assembly 18 includes a second electric telescopic rod 181, an adjustment roller 182 is installed at the bottom end of the second electric telescopic rod 181, a fixing seat 183 is fixedly installed on one side of the second electric telescopic rod 181, a second screw 184 is threadedly connected to the middle of the fixing seat 183, and a pressure roller 185 is rotatably connected to the bottom end of the second screw 184. The second electric telescopic rod 181 is fixed to one end of the outer surface of the special-shaped box 9 by bolts. When the label paper extends from the bottom of the frame 1 to the adjustment roller, it passes through the adjustment roller and then passes through the bottom of the first storage box 53. A round rod is rotatably installed at the edge of the bottom of the extension plate 57 on the side of the first storage box 53 close to the side of the special-shaped box 9. When the label paper passes through the bottom of the first storage box 53, when the tension adjustment assembly 18 adjusts the tension of the label paper, the upper surface of the label paper is in rotational contact with the round rod to prevent the label paper from directly contacting the edge of the extension plate 57. A fixing seat is welded on one side of the second electric telescopic rod, and the second screw is threadedly connected to the fixing seat. The second screw A pressure roller is installed at the bottom of the rod, and the bottom of this pressure roller slightly exceeds the Y-axis slider 4 to prevent the label paper from contacting the bottom of the Y-axis slider 4. During the transmission of the label paper, the fonts and patterns on the surface are scratched due to friction, affecting the processing quality of the label paper. There is enough space between the Y-axis slider 4 and the frame 1. The tension adjustment component 18 is in this space, which does not affect the position adjustment of the Y-axis slider 4 along the frame 1. When cutting label papers of different materials, when replacing the label paper to be cut, the staff can manually turn the second screw to adjust the position of the pressure roller to avoid the distance between the pressure roller and the label paper being too close, affecting the normal transmission of the label paper. The second electric telescopic rod cooperates with the industrial-grade camera on the digital die-cutting machine. When it is detected that the position of the cut label paper is deformed, the second electric telescopic rod controls the movement of the adjustment roller to adjust the tension of the label paper. Since the tightness of the label paper wound on the winding roller cannot be guaranteed, the tension adjustment component 18 can deal with this emergency and adjust the tension of the label paper to ensure the cutting quality of the label paper. A cleaning structure 19 is also provided inside the first storage box 53. The cleaning structure 19 includes a sleeve plate and an inner plate. One end of the inner plate extends into the sleeve plate. Slide grooves are provided on one side of the partition plate 71 and one side of the inner wall of the first storage box 53. The slider at one end of the sleeve plate and the slider at one end of the inner plate extend into the two slide grooves respectively. When the position of the knife setting assembly 16 is adjusted, the sleeve plate can move together. A slide rod is fixed to one end of the back of the inner plate. One end of the slide rod passes through the first storage box 53 and extends to the outside of the first storage box 53. At the same time, a spring is provided on the surface of the slide rod. The height of the sleeve plate and the inner plate is lower than the limit rod 54 and the scraper assembly 6. When an electric telescopic rod 52 is retracted, one end of the slide rod can contact the outer wall of the special-shaped box 9, so that the sleeve plate and the inner plate move along the slide groove. When the cutting fluid inside the first storage box 53 is replaced, the small amount of cutting fluid remaining in the first storage box 53 is also scraped into the bent discharge pipe 55 to avoid the cutting fluid that is re-injected into the first storage box 53 and mixed with the cutting fluid that has been used many times before, which affects the quality of the cutting fluid and causes this batch of cutting fluid to be used fewer times, requiring more frequent replacement of the cutting fluid. Under the action of the spring, when the first storage box 53 moves to the bottom end of the tool setting assembly 16, the cleaning structure 19 returns to its original state.

[0024] In the present application, the immersion cleaning mechanism 5 includes a folding frame 51, one end of the folding frame 51 is fixedly installed with the Y-axis slider 4 by screws, and the other end of the folding frame 51 is fixedly connected to a first electric telescopic rod 52, one end of the first electric telescopic rod 52 is fixedly installed with a first storage box 53, and two limit rods 54 are fixedly installed in parallel inside the first storage box 53, a bent discharge pipe 55 is fixedly installed on one side of the outer surface of the first storage box 53, and a bent discharge pipe 56 is fixedly installed on the other side of the outer surface of the first storage box 53, and extension plates 57 are fixedly connected to both sides of the outer surface of the first storage box 53, and the two extension plates 57 are respectively located at the bottom of the bent discharge pipe 55 and the bent discharge pipe 56.

[0025] It should be noted that the end of the folding frame 51 is fixed to the Y-axis slider 4 by screws, and the immersion cleaning mechanism 5 can be easily disassembled when not needed. The first electric telescopic rod 52 is connected to the external power supply through a power cord and is controlled by the control device on the digital die-cutting machine. The end is installed together with the first storage box 53 by bolts. The length of the first storage box 53 is the same as the length of the Y-axis slider 4. Two limit rods 54 are fixed in parallel inside the first storage box 53. Both ends of the connecting sleeve 61 are sleeved on the two limit rods 54 and can move parallel to the two limit rods 54. The length of the bent discharge pipe 55 is greater than the length of the bent discharge pipe 56, and the length of the bent discharge pipe 56 is greater than the length of the bent discharge pipe 56. It should be shorter than the shortest retractable distance of the eight cutting heads in the automatic tool setting mechanism to avoid the bending discharge pipe 56 injecting the cutting fluid into the side of the blocking partition component 7 when the cutting fluid is injected into the first storage box 53, and the amount of cutting fluid used each time cannot be saved. Two extension plates 57 are fixed to the outside of the first storage box 53, extending outward from the bottom of the bent discharge pipe 55 and the bent discharge pipe 56, increasing the width of the first storage box 53, avoiding the cutting head being immersed in the first storage box 53. When the scraping component 6 rotates, the cutting fluid inside splashes out and wets the label paper below, affecting the subsequent cutting of the label paper by the cutting head, and may directly affect the processing quality of the label paper.

[0026] In the present application, a blocking and partitioning assembly 7 is fixedly installed on one side of one of the connecting sleeves 61, and the blocking and partitioning assembly 7 includes a partition plate 71, and two connecting holes 72 are provided on the surface of the partition plate 71. The inner walls of the two connecting holes 72 are adhered with rectangular silicone sleeves 73, and the edges of the partition plate 71 are adhered with silicone strips 74. The two limiting rods 54 pass through the two connecting holes 72, and the inner edges of the rectangular silicone sleeves 73 are in contact with the limiting rods 54, and the outer edges of the silicone strips 74 are in contact with the inner walls of the first storage box 53.

[0027] It should be noted that the blocking and partitioning component 7 is fixed on one side of a scraping component 6 at the edge, while the position of the scraping component 6 at the other end is relatively fixed. There is a certain distance between the blocking and partitioning component 7 and this scraping component 6, ensuring that the existence of the blocking and partitioning component 7 will not affect the normal immersion of the cutting head in the cutting fluid, and as this scraping component 6 moves normally, the volume inside the first storage box 53 is changed. When the eight scraping components 6 and the cutting head are close, less cutting fluid can be used. The positions of the two connecting holes 72 and the two limiting rods 54 correspond. The rectangular silicone sleeve 73 and the silicone strip 74 are adhered to the partition plate 71. The inner wall of the rectangular silicone sleeve 73 contacts the limiting rod 54, and the silicone strip 74 contacts the inner wall of the first storage box 53. When the blocking and partitioning component 7 moves, the sealing is strong and the cutting fluid can be blocked.

[0028] In the present application, one end of the bent discharge pipe 55 and the bent inlet pipe 56 are both fixedly installed with a telescopic hose 8, one end of one of the telescopic hoses 8 is fixedly installed with a special-shaped box 9, the interior of the special-shaped box 9 is slidably connected with a second storage box 10, and one end of the other telescopic hose 8 passes through the special-shaped box 9 and extends to the interior of the second storage box 10, and the bottom end of this telescopic hose 8 is fixedly installed with a micro pump.

[0029] It should be noted that the telescopic hose 8 fixedly connected at the ends of the bent discharge pipe 55 and the bent discharge inlet pipe 56 are of different lengths. The telescopic hose 8 installed at the end of the bent discharge inlet pipe 56 is longer and directly extends to the inside of the second storage box 10. The cutting fluid in the second storage box 10 can be directly pumped out by relying on a micro pump. There is a certain distance between the top of the second storage box 10 and the top of the inner wall of the special-shaped box 9. When the second storage box 10 is pulled out of the special-shaped box 9, the telescopic hose 8 and the micro pump can be moved away from the distance difference between the two, which is convenient for replacing the cutting fluid in the second storage box 10. A thermometer and a cutting fluid concentration detector are installed inside the second storage box 10 to monitor the temperature and viscosity of the cutting fluid inside the second storage box 10. When the temperature or viscosity of the cutting fluid changes, the cutting fluid inside the second storage box 10 is replaced or cooled in time to avoid the increase in the cutting fluid temperature causing the viscosity to increase, which affects the subsequent lubrication of the cutting head and also affects the cooling effect of the cutting head. An ultraviolet lamp is installed on the top of 9 to prevent the second storage box 10 from storing the cutting fluid. Since the cutting fluid needs to be transferred to the first storage box 53 for use and has contact with the outside, microorganisms are easily mixed into the cutting fluid in the second storage box 10, causing the cutting fluid to gradually deteriorate and stink, affecting the processing effect and workpiece quality. When the temperature of the cutting fluid rises to a certain temperature or the thickness of the cutting fluid rises to a certain thickness value, an alarm is directly sounded through the alarm on the second storage box 10, waiting for the staff to handle it. The alarm, the control device connected to the thermometer and the cutting fluid concentration detector, and the ultraviolet lamp are connected to the power supply device in the entire digital die-cutting machine through a power cord. When the cutting fluid in the second storage box 10 becomes viscous due to the temperature rise and causes the alarm to sound, the staff can quickly pull out the second storage box 10 and replace the cutting fluid inside. If the cutting fluid is used for a short time, a part of the second storage box 10 can be pulled out, and water can be added to dilute and cool it down through the space between the second storage box 10 and the special-shaped box 9; In order to timely discover the abnormal situation of the cutting fluid in the second storage box 10, the intelligent control processor is used to control the processor to perform corresponding operations to ensure that the cutting fluid in the second storage box 10 can maintain a normal viscosity during the entire use process. The specific operations are as follows: A temperature sensor is installed inside the second storage box 10 to monitor the temperature data of the cutting fluid in the second storage box 10 in real time; a conductivity meter is installed inside the second storage box 10 to monitor the impurity content of the cutting fluid in the second storage box 10 in real time. The controller is used to analyze the collected data in real time to determine the temperature data and impurity content of the cutting fluid in the second storage box 10, specifically including: The thickness of the cutting fluid in the second storage box 10 is compared with the preset thickness. When the thickness of the cutting fluid in the second storage box 10 is greater than the preset thickness, a thickness abnormality monitoring signal is generated. At the same time, the thickness of the cutting fluid is subtracted from the preset thickness of the cutting fluid to obtain a thickness difference. The thickness difference is analyzed, specifically: When the difference in consistency is less than the preset consistency value, the temperature value of the cutting fluid is analyzed, including: When the temperature value is less than the preset temperature value, a temperature abnormality monitoring signal is generated, and the temperature value of the cutting fluid in the second storage box 10 within ten minutes before the current moment is obtained and the average value is calculated to obtain the temperature average value 1, and at the same time, the time of the minimum temperature value is counted, and the minimum temperature interval duration is obtained by subtracting it from the current moment; when there are multiple minimum temperature values ​​counted, the temperature value closest to the current moment is selected; the value of the minimum temperature interval duration is compared with the temperature average value 1 to obtain the temperature change value 1; When the temperature value is greater than the preset temperature value, the temperature value of the cutting fluid is analyzed, and the temperature value of the cutting fluid in the second storage box 10 within ten minutes after the current moment is obtained and the average value is calculated to obtain the temperature average value 2. At the same time, the time of the maximum temperature value is counted, and the maximum temperature interval duration is obtained by subtracting it from the current moment; when there are multiple maximum temperature values ​​counted, the temperature value closest to the current moment is selected; the value of the maximum temperature interval duration is compared with the temperature average value 2 to obtain the temperature change value 2; When the difference in consistency is greater than the preset consistency value, the impurity value of the cutting fluid is analyzed, including: When the impurity value is greater than the preset impurity value, an impurity abnormality monitoring signal is generated, and the impurity value of the cutting fluid in the second storage box 10 every five minutes before the current moment is obtained, and the impurity value of two adjacent five-minute impurity values ​​is subtracted and divided by the number of impurity values ​​every five minutes to obtain the impurity change value; Based on the temperature variation value 1, temperature variation value 2 and miscellaneous variation value, the changing trend and potential problems of the cutting fluid state can be further evaluated through calculation. The specific steps are as follows: Analysis of temperature change value 1: If the temperature change value 1 is large, it means that the temperature of the cutting fluid has changed dramatically in the past ten minutes. There may be problems such as abnormal operation of the cooling system or the influence of external ambient temperature. At this time, the operation of the cooling system should be checked to ensure that it is working properly, and consider adjusting the cooling conditions to stabilize the temperature of the cutting fluid.

[0030] Analysis of temperature variation value 2: For temperature variation value 2, if the value is large, it means that the temperature of the cutting fluid may fluctuate greatly in the next ten minutes. This may be caused by excessive heat generated during the processing or reduced efficiency of the cooling system. It is recommended to monitor the temperature changes in the future and take timely measures to prevent overheating.

[0031] Analysis of impurity value: The impurity value reflects the rate of change of impurity content in cutting fluid over time. A high impurity value means that the impurity content in cutting fluid increases rapidly in a short period of time, which may be due to the failure to effectively filter fine particles such as metal chips during the cutting process. In this regard, the filter device should be cleaned in time and new filter materials should be replaced if necessary to ensure the cleanliness of the cutting fluid.

[0032] In the present application, guide rails 17 are fixedly connected to both sides of the inner surface of the special-shaped box 9 and located below the telescopic hose 8. A rectangular frame 11 is provided inside the special-shaped box 9 and between the two guide rails 17. A filter screen 12 is paved at the bottom of the rectangular frame 11. A circular splash plate 111 is fixedly connected to the center of the inner part of the rectangular frame 11. Baffles 112 are fixedly connected to both sides of the inner wall of the rectangular frame 11. A recovery mechanism 13 for recovering metal debris from the cutting fluid is provided in the middle of the inner part of the rectangular frame 11. The recovery mechanism 13 includes a magnetic conical bucket 131 fixedly connected to the middle of the inner part of the rectangular frame 11. The bottom of the magnetic conical bucket 131 is A leakage plate 132 is fixedly connected to the edge of the leakage plate 132, the bottom of the leakage plate 132 is fixedly connected to a collecting box 134, and a collecting port 133 is opened at the connection between the leakage plate 132 and the collecting box 134, a servo motor 135 is fixedly installed on the top of the magnetic conical bucket 131, the output shaft of the servo motor 135 passes through the magnetic conical bucket 131 and is fixedly connected to a disc 136, both sides of the upper surface of the disc 136 are fixedly connected to a first support rod 137, one end of the first support rod 137 is fixedly connected to a scraper 138, the bottom of the scraper 138 is fixedly connected to a second support rod 139, one end of the second support rod 139 is fixedly connected to a wiping plate 140.

[0033] It should be noted that the two guide rails 17 are installed and fixed on both sides of the inner wall of the special-shaped box 9 to provide a fixed position for the rectangular frame 11, and the filter screen 12 is laid at the bottom of the rectangular frame 11. When the digital die-cutting machine is suspended, the rectangular frame 11 can be pulled out from the guide rails 17, and the filter screen 12 can be directly uncovered from the bottom of the rectangular frame 11, and the filter screen 12 can be replaced. The distance between the magnetic conical bucket 131 and the telescopic hose 8 is relatively close. When the cutting fluid contacts the magnetic conical bucket 131, the circular splash plate 111 can prevent the cutting fluid from flowing to other positions, ensuring that the cutting fluid flows along the inclined surface of the magnetic conical bucket 131, and the metal debris mixed in the cutting fluid can be adsorbed on the inclined surface of the magnetic conical bucket 131, and the treated cutting fluid falls on the leak plate 132, flows through its leak hole to the filter screen 12, and then is filtered by the filter screen 12, so that the cutting fluid is further filtered and treated, thereby improving the quality of the treated cutting fluid. When the metal debris adsorbed on the magnetic conical bucket 131 needs to be processed regularly, the injection of cutting fluid can be stopped, and the servo motor 135 can be started so that its output shaft drives the disc 136 to rotate, thereby using the first support rod 137 to drive the scraper 138 to clean the magnetic conical bucket 131, so that the metal debris falls onto the leakage plate 132. During the rotation of the scraper 138, the second support rod 139 is used to drive the wiping plate 140 to rotate at the same time, so that the fallen metal debris enters from the collecting port 133 and is collected in the collecting box 134, and the metal debris falling through the leakage hole is blocked by the filter mesh 12, which facilitates the subsequent processing of the metal debris.

[0034] In the present application, a folding rod 68 is fixedly installed on one side of the connecting sleeve 61 , a limiting sleeve 69 is sleeved on one end of the folding rod 68 , and a folding fixing seat 610 is fixedly installed on the top of the outer surface of the limiting sleeve 69 .

[0035] In the present application, a Z-axis servo motor 14 is fixedly installed on the top of the Y-axis slider 4, one end of the output shaft of the Z-axis servo motor 14 is fixedly connected to a Z-axis lead screw 15 through a coupling, the surface of the Z-axis lead screw 15 is threadedly connected to a tool setting assembly 16 by means of a screw block, and a plurality of the folding fixing seats 610 are fixedly installed with the sub-machine head slider in the tool setting assembly 16 by bolts.

[0036] It should be noted that a folding rod 68 is welded on one side of each connecting sleeve 61, and the limiting sleeve 69 corresponds to the position and size of the folding rod 68. The folding fixing seat 610 is installed together with the sub-head slider of the tool setting assembly 16. When the first electric telescopic rod 52 controls the contraction of the first storage box 53, one end of the folding rod 68 contracts toward the inside of the limiting sleeve 69, and the Z-axis servo motor 14 drives the tool setting assembly 16 to move up and down through the Z-axis screw 15. When the tool setting assembly 16 moves up and down, and when the first electric telescopic rod 52 controls the first storage box 53 to move forward and backward, the cutting head installed on the sub-head slider in the tool setting assembly 16 can be immersed downward in the cutting fluid in the first storage box 53, thereby realizing cooling, lubrication and cleaning of the cutting head in the automatic tool setting mechanism.

[0037] In the present application, the bottom of the inner surface of the first storage box 53 is inclined toward the bent discharge pipe 55, a control valve is fixedly installed at one end of the bent discharge pipe 55, and an extraction pump is installed at the bent discharge pipe 55 and on one side of the control valve.

[0038] It should be noted that there are more connections between the bent discharge tube 55 and the first storage box 53, so the cutting fluid in the first storage box 53 can be extracted more quickly, and the first storage box 53 is inclined toward the bent discharge tube 55, and the bottom of the inner wall of the first storage box 53 is kept parallel to the inner wall of the bent discharge tube 55, so as to avoid the residual cutting fluid inside the first storage box 53 when the cutting fluid in the first storage box 53 is extracted. The control valve is a solenoid valve, which is controlled by the controller, and the extraction pump on the bent discharge tube 55 extracts the cutting fluid in the first storage box 53.

[0039] In the present application, the special-shaped box 9 can be fixedly installed with the other side of the bottom of the Y-axis slider 4 by bolts, and there is a certain distance between the bottom end and the X-axis assembly of the digital die-cutting machine and the label paper.

[0040] In the present application, the width of the two extension plates 57 does not exceed the range of the bent discharge pipe 55 and the bent inlet pipe 56 , and the tops of the two extension plates 57 are inclined toward the middle of the outer wall of the first storage box 53 .

[0041] It should be noted that there is a certain distance between the special-shaped box 9 and the bottom of the first storage box 53 and the X-axis assembly and the label paper, ensuring that the staff can pass the label paper through them and that the digital die-cutting machine can cut the label paper normally afterwards. The two extension plates 57 are inclined toward the first storage box 53. When the cutting fluid inside the first storage box 53 splashes out, it is blocked by the extension plates 57 to avoid splashing directly onto the label paper below and affecting the production quality of the label paper.

[0042] When the present invention is specifically implemented: According to the present invention, when the digital die-cutting machine is used to cut the label paper, one end of the label paper passes through the bottom of the X-axis assembly and the immersion cleaning mechanism 5, and then the staff adjusts the position of the label paper according to the position where the cutting is required. During the adjustment, the Y-axis servo motor 2 drives the Y-axis slider 4 to move along the frame 1 through the Y-axis lead screw 3, and then the sub-head motor and the sub-head lead screw in the knife assembly 16 are started, driving the eight sub-head sliders and the cutting heads installed on each sub-head slider to adjust the appropriate distance. When the sub-head slider moves, the folding fixing seat 610 and the limiting sleeve 69 move together with the sub-head slider, and the folding rod 68 and the like are also driven by the limiting sleeve 69, so that they can move parallel to the limiting rod 54 inside the first storage box 53. After the positions of the eight sub-head sliders, sub-heads and scraping components 6 are adjusted appropriately, the X-axis component, Z-axis servo motor 14 and Z-axis lead screw 15 are started. Driven by the X-axis component, the label paper is transported, and at the same time, the knife assembly 16 moves downward to make the sub-head slider and the cutting head cut the label paper. After the cutting head finishes cutting the label paper at one place, the knife assembly 16 moves up and exceeds the height of the first storage box 53. Then the first electric telescopic rod 52 extends to push the first storage box 53 to one end for a fixed distance, so that the center of the pressing plate 66 in the scraping component 6 is perpendicular to the cutting head. Then the Z-axis servo motor 14 drives the knife assembly 16 to move downward through the Z-axis lead screw 15. The tip of the cutting head in the knife assembly 16 first contacts the turntable in the middle of the pressing plate 66, and in the process of continuing to press downward, the first screw 65 will rotate and move downward inside the screw hole 62, and in the process of the first screw 65 rotating and moving downward, the two The cleaning brush 67 can rotate to contact the cutting head to clean the surface of the cutting head. After that, the cutting head is immersed in the cutting fluid in the first storage box 53, the cutting fluid is stained on the cutting head, and the cutting head is cooled. At the same time, the metal debris, hair and the like remaining on the surface of the cutting head after cleaning can be taken away by the cutting fluid and mixed into the cutting fluid. Then, the Z-axis servo motor 14 and the Z-axis lead screw 15 drive the knife setting assembly 16 to move upward, the cutting head rises, the pressure on the spring 63 gradually decreases and returns to its original shape, and the first screw rod 65 can rotate upward under the restriction of the screw hole 62, and the pressure plate 66 and the two cleaning brushes 67 rotate with the first screw 65, and the cleaning brush 67 can scrape off the excess cutting fluid adhering to the surface of the cutting head. After the position between the cutting head and the cleaning brush 67 is staggered, the first electric telescopic rod 52 retracts again to leave the range of the cutting head, and then the cutting head can continue to cut the label paper downward; After the cutting fluid in the first storage box 53 has been used for a certain period of time, in order to prevent the cutting fluid from becoming gradually viscous and affecting the normal lubrication of the cutting head, after the cutting head is soaked in the cutting fluid and leaves, the extraction pump on the bent discharge pipe 55 can extract the cutting fluid in the first storage box 53, and when the cutting fluid enters the special-shaped box 9 through the telescopic hose 8, the cutting fluid first contacts with the magnetic conical bucket 131, and the metal debris that may be mixed in the cutting fluid can be adsorbed by the magnetic conical bucket 131, and then the cutting fluid continues to fall downward through the leak plate 132 to the filter screen 12, and the hair mixed in the cutting fluid is filtered out by the filter screen 12, and the filtered cutting fluid can be mixed with the cutting fluid in the second storage box 10 again; After all the cutting fluid in the first storage box 53 is extracted, the micro pump on the other telescopic hose 8 can extract the cutting fluid in the second storage box 10 and send it to the first storage box 53. Then the cutting head can continue to extend into the cutting fluid in the first storage box 53 to continue to lubricate, clean and cool the cutting head.
