[0001] The utility model relates to the technical field of material cutting, and particularly relates to a laser die with adjustable spacing. Background Art

[0002] A "laser die" is a die made by using laser technology, which has the characteristics of high precision, high speed and high flexibility. Compared with traditional dies, laser dies can cut various materials more precisely, such as paper, plastic, leather, etc.

[0003] The existing Chinese patent: a laser die, patent number: CN205415839U, includes a die plate and at least two blades located on the die plate. The blade includes a side portion extending along a straight line on one side thereof, two end portions respectively extending away from the side portion from both ends of the side portion, and two connecting portions respectively extending from one end of both end portions away from the side portion towards the middle of the blade. The connecting portions extend in a straight line and are parallel to the side portion. A groove formed by laser ablation and matching the shape of the blade is provided on the die plate. The blade is embedded in the groove and fixedly connected to the die plate. The distance between the side portion and the connecting portion is equal to the spacing between adjacent two blades. When cutting materials with this utility model, the pressure borne by the blade is less than that of the existing blades with a closed annular structure. The finished products cut on the material are arranged without spacing, so that the material is fully utilized and the waste of material is avoided.

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems: for the above-mentioned laser die, the cut finished products can be arranged without spacing, but when there are damages and defects on the cutting material, it is difficult for the cutting die to accurately avoid the damaged parts. The materials around the damaged parts are cut off and cannot be used, resulting in waste of materials. Summary of the Utility Model

The materials around the damaged parts are cut off and cannot be used, resulting in waste of materials.

[0007] (2) Technical Solutions

[0008] To achieve the above object, the utility model is realized through the following technical solutions:

[0009] A laser knife die with fine-tunable spacing comprises a base, a spacing adjustment mechanism and a cutting mechanism. A metal sliding rod is fixedly mounted on the base, a threaded rod is rotatably mounted on the base, a scale is fixedly mounted on the side end of the base, the spacing adjustment mechanism comprises a support, a semi-threaded sleeve, a pull handle, a spring, a magnetic sheet, a magnetic ring and a slot, and the cutting mechanism comprises a knife plate, a metal sheet and a block.

[0010] Preferably: the metal sheet is fixedly mounted on the bottom end of the knife plate.

[0011] Preferably: the clamping block is arranged at the bottom end of the knife plate.

[0012] (III) Beneficial effects

[0013] 1. Place the blade of the corresponding shape on the support according to the cutting requirements so that the card block can be inserted into the card slot. The suction force of the magnetic ring on the metal sheet will firmly fix the blade on the support. During the cutting process, the card block is stuck in the card slot to prevent the blade from displacement and improve stability. There are multiple supports on the base. If only three need to be cut, only three blades need to be installed. The empty support will not cut the material. The magnetic ring absorbs the metal sheet and the card slot to clamp the card block, so that the blade can be disassembled and replaced quickly and stably.

[0014] 2. When the material is damaged and the cutting position needs to be adjusted, pull the handle on the support that does not need to be adjusted upwards, and the handle will pull the semi-threaded sleeve to overcome the elastic force of the spring and slide upwards, and then rotate the handle counterclockwise to make the handle clamp the side of the support, so that the semi-threaded sleeve in the support that does not need to slide can be disengaged from the engagement with the threaded rod, and then rotate the threaded rod, and the threaded rod can be engaged with the semi-threaded sleeve in the support that needs to slide, so as to achieve the adjustment of the spacing between the supports. The engagement of the threaded rod and the semi-threaded sleeve can achieve stepless adjustment of a small distance, and the support can be made to slide precisely and tiny in combination with the scale. When the support is adjusted into place, rotate the handle clockwise to reset the semi-threaded sleeve and clamp the threaded rod to fix it. By controlling the engagement of the semi-threaded sleeve and the threaded rod on the support, the fixation and movement of the support are completed, so that multiple supports can be individually adjusted in micro-distance, thereby achieving the effect of being able to adjust according to production needs and material conditions and improving material utilization.

[0023] Embodiments of the present application provide a laser die mold with adjustable spacing, effectively solving the above-mentioned technical problem of the laser die mold. The laser die mold can cut out finished products in a non-spacing arrangement. However, when there are damages and defects on the cutting material, it is difficult for the cutting die mold to accurately avoid the damaged areas. After the materials around the damaged areas are cut off, they cannot be used, resulting in waste of materials. According to the cutting requirements, the die plate with the corresponding shape is placed above the supporting table, so that the clamping block can be inserted into the clamping groove. The suction force of the magnetic suction ring on the metal sheet will firmly fix the die plate above the supporting table. During the cutting process, the clamping block clamping the clamping groove can prevent the die plate from shifting, improving stability. There are multiple supporting tables on the base. If only three cuts are needed, only three die plates need to be installed. The vacant supporting tables will not cut the material. By using the magnetic suction ring to adsorb the metal sheet and the clamping groove to clamp the clamping block, the effect of quickly and stably disassembling, installing and replacing the die plate is achieved. When encountering situations where the cutting position needs to be adjusted due to damages on the material, etc., pull up the handle on the supporting table that does not need to be adjusted. The handle will pull the half-threaded sleeve to slide upward against the elastic force of the spring, and then rotate the handle counterclockwise to make the handle clamp the side of the supporting table, so that the half-threaded sleeve in the supporting table that does not need to slide can be disengaged from the engagement with the threaded rod. Then rotate the threaded rod. The threaded rod drives the corresponding supporting table to slide through the engagement with the half-threaded sleeve in the supporting table that needs to slide, thereby realizing the adjustment of the spacing between the supporting tables. The engagement between the threaded rod and the half-threaded sleeve can achieve stepless adjustment of a small distance. Cooperating with the scale, the supporting table can slide precisely and slightly. When the supporting table is adjusted in place, rotate the handle clockwise to make the half-threaded sleeve reset and clamp the threaded rod for fixation. By controlling the engagement between the half-threaded sleeve and the threaded rod on the supporting table, the fixation and movement of the supporting table are completed, enabling multiple supporting tables to all perform independent micro-adjustments, achieving the effect of being able to adjust according to production requirements and material conditions and improving the material utilization rate.

[0024] Embodiment

[0025] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, the technical solution in the embodiments of the present application effectively solves the above-mentioned technical problem of the laser die mold. The laser die mold can cut out finished products in a non-spacing arrangement. However, when there are damages and defects on the cutting material, it is difficult for the cutting die mold to accurately avoid the damaged areas. After the materials around the damaged areas are cut off, they cannot be used, resulting in waste of materials. The general idea is as follows:

[0026] In view of the problems existing in the prior art, the utility model provides a laser knife die with adjustable spacing, which includes a base 1, a distance adjusting mechanism and a cutting mechanism. A metal sliding rod 2 is fixedly installed on the base 1, a threaded rod 3 is rotatably installed on the base 1, and a scale 12 is fixedly installed on the side end of the base 1. The distance adjusting mechanism includes a support table 4, a half-threaded sleeve 5, a pull handle 6, a spring 7, a magnetic sheet 8, a magnetic ring 9 and a card slot 11. The cutting mechanism includes a knife plate 13, a metal sheet 14 and a clamping block 15.

[0027] The support table 4 is slidably installed above the base 1, the half-threaded sleeve 5 is slidably installed inside the base 1, the pull handle 6 is rotatably installed at the top end of the half-threaded sleeve 5, and the spring 7 is fixedly installed between the support table 4 and the half-threaded sleeve 5; the metal sliding rod 2 and the threaded rod 3 pass through the through holes on both sides of the support table 4.

[0028] The magnetic ring 9 is fixedly installed at the top end of the support table 4, the card slot 11 is opened at the top end of the support table 4, the magnetic sheet 8 is fixedly installed at the side end of the support table 4, the metal sheet 14 is fixedly installed at the bottom end of the knife plate 13, and the clamping block 15 is opened at the bottom end of the knife plate 13.

[0029] Working principle:

[0030] First step, the cutting shape of the knife plate 13 can be customized according to production requirements. During use, according to the cutting requirements, the knife plate 13 with the corresponding shape is placed above the support table 4 so that the clamping block 15 can be inserted into the card slot 11. The suction force of the magnetic ring 9 on the metal sheet 14 will firmly fix the knife plate 13 above the support table 4. During the cutting process, the clamping block 15 clamping the card slot 11 can prevent the knife plate 13 from shifting, improving stability. There are multiple support tables 4 on the base 1. If only three cuts are needed, only three knife plates 13 need to be installed. The vacant support tables 4 will not cut the material. By the magnetic ring 9 adsorbing the metal sheet 14 and the card slot 11 clamping the clamping block 15, the effect of quickly and stably disassembling, installing and replacing the knife plate 13 is achieved.

[0031] In the second step, multiple supports 4 are installed on the base 1, which can cut multiple finished products at the same time. When the material is damaged and the cutting position needs to be adjusted, the handle 6 on the support 4 that does not need to be adjusted is pulled upward, and the handle 6 will pull the semi-threaded sleeve 5 to overcome the elastic force of the spring 7 and slide upward. Then, the handle 6 is rotated counterclockwise to make the handle 6 catch the side of the support 4, so that the semi-threaded sleeve 5 in the support 4 that does not need to slide can be disengaged from the threaded rod 3, and then the threaded rod 3 is rotated. The threaded rod 3 can drive the corresponding support 4 to slide by engaging with the semi-threaded sleeve 5 in the support 4 that needs to slide, thereby realizing the adjustment of the distance between the support 4, and the engagement of the threaded rod 3 and the semi-threaded sleeve 5 can be realized. The present invention provides stepless adjustment of tiny distances, and cooperates with the scale 12 to enable the support platform 4 to slide tiny and accurately. When the support platform 4 is adjusted into place, the pull handle 6 is rotated clockwise to reset the half-threaded sleeve 5 to clamp the threaded rod 3 for fixation. In this process, the magnetic suction piece 8 at the side end of the support platform 4 generates a slight adsorption force on the metal slide rod 2 through the support platform 4, which can fix the support platform 4 that does not need to be moved, and at the same time does not affect the sliding of the support platform 4 that needs to be moved. By controlling the engagement of the half-threaded sleeve 5 on the support platform 4 and the threaded rod 3, the fixation and movement of the support platform 4 are completed, so that multiple support platforms 4 can all be individually adjusted in micro-distances, achieving the effect of being able to adjust according to production needs and material conditions and improving material utilization.

[0032] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
