[0003] Most printed materials have patterns on them. When die-cutting such materials, it is necessary to ensure that the material strip is transported stably and straightly so that the tool can accurately die-cut onto the product to achieve the required effect. Therefore, a die-cutting machine with small die-cutting error is needed to meet production needs. Summary of the Invention

[0004] In order to ensure the straight conveyance of the material strip and improve the production quality of printed products, the present application provides an automatic label tracking printing and die-cutting device.

[0005] This application provides an automatic tracking label printing and die-cutting device, which adopts the following technical solutions:

[0006] An automatic label tracking printing and die-cutting device includes a layout base and a material tape drum, a die-cutting unit and a material receiving drum installed in sequence on the layout base. The material tape drum is provided with a material tray for loading the printing material tape, and the printing material tape passes through the die-cutting unit and is wound and rolled up on the material receiving drum; a corrector for correcting the position of the printing material tape is provided between the material tape drum and the die-cutting unit, and a storage table is provided at the input end of the die-cutting unit, and an electronic eye for automatic label tracking is installed on the storage table.

[0007] By adopting the above technical solution, when the automatic tracking label printing and die-cutting device is working, the printed material strip with regular patterns passes through the electronic eye in turn. If the pattern is offset through the electronic eye scanning, the electronic eye will feedback the correction signal to the corrector to control the operation of the corrector transmission axis, and correct the printed material strip in the direction of travel into a straight line. At the same time, the electronic eye in the form of automatic tracking label correction adjusts the material strip travel speed of the die-cutting device, so that the corresponding tool of the die-cutting unit can accurately die-cut onto the printed material strip, thereby ensuring that the output of products with precise patterns can be completed with quality and quantity, and ensuring high dimensional accuracy.

[0009] By adopting the above technical solution, since there are many types of printing strips, the width of the strips themselves and the position of the patterns are different each time, the position of the electronic eye needs to be adjusted accordingly before the automatic tracking printing and die-cutting device works. In order to facilitate the adjustment of the position of the electronic eye, an adjustment mechanism is provided on the storage table for adjusting the position along the width direction of the printing strip.

[0010] Optionally, the adjustment bracket includes a connecting rod and support rods detachably mounted on both ends of the connecting rod, and the connecting rod and the two support rods constitute a U-shaped frame body of the adjustment bracket.

[0011] By adopting the above technical solution, the U-shaped frame can be conveniently set up on the storage table of the die-cutting unit so that the electronic eye can move horizontally to compare the printed material strip pattern.

[0012] Optionally, a sleeve is provided at the end of the support rod, the end of the connecting rod is inserted into the sleeve, and the connecting rod is fixed in the sleeve by a fastener.

[0016] Optionally, the angle adjustment assembly includes a mounting plate for mounting the electronic eye, an adjusting member arranged below the mounting plate for adjusting the angle of the mounting plate, and a limiting member arranged on the adjusting member for positioning the mounting plate.

[0017] By adopting the above technical solution, the fixing of the mounting plate enables the electronic eye to be fixed at a specific angle, and the printed material strip is corrected, so that the printed material strip forms a straight line, ensuring that the output of products with precise patterns can be completed with guaranteed quality and quantity, and ensuring high dimensional accuracy.

[0018] Optionally, the adjusting member includes a connecting plate fixed to the connecting pipe and an adjusting rod fixed to the bottom of the mounting plate, the adjusting rod is rotatably engaged with the connecting plate, a circular toothed disc is radially distributed on the adjusting rod, and the limiting member is snap-engaged with the circular toothed disc.

[0019] By adopting the above technical solution, the mounting plate can rotate around the axis of the adjusting rod, so that the electronic eye is fixed on the mounting plate, thereby realizing the horizontal angle adjustment of the electronic eye, making it convenient for the electronic eye to compare with the printed material pattern.

[0020] Optionally, the limiting member has a folding rod shape, and the turning point of the limiting member is a hinge point hinged to the side wall of the connecting plate; the limiting member includes a force-applying part and a limiting part, and a clamping platform is fixedly connected to the limiting part, and the clamping platform is clamped with the circular gear disk; a tension spring is arranged between the limiting part and the connecting plate, and the tension spring applies tension to the limiting part.

[0021] By adopting the above technical solution, the tension spring applies tension to the limiting part, so that it is always engaged with the teeth of the circular gear disc in the absence of external force, thereby limiting the rotation of the circular gear disc and improving the stability of the mounting plate.

[0027] The present application is further described in detail below with reference to the accompanying drawings.

[0028] The embodiment of the present application discloses an automatic tracking label printing and die-cutting device.

[0029] Reference Figure 1 The automatic tracking label printing and die-cutting device includes a layout base 1, and a material belt drum 11, a corrector 2, a die-cutting unit 12 and a material receiving drum 13 installed on the layout base 1.

[0030] A tray for loading printed material is mounted on the web drum 11. Along the web's travel direction, the web guide 2 and die-cutting unit 12 are sequentially mounted behind the web drum 11. The die-cutting unit 12 has a storage platform 121 at its entrance, on which is mounted an electronic eye 3 for automatic label tracking. This electronic eye 3 is signal-connected to the web guide 2 and the die-cutting unit's internal processor. A material collection drum 13 is located at the die-cutting unit 12's exit.

[0031] When the automatic tracking label printing and die-cutting device is working, the printed material strip with regular patterns passes through the electronic eye 3 in sequence. If the pattern is offset by the electronic eye 3, the electronic eye 3 will feed back the correction signal to the corrector 2, control the transmission axis of the corrector 2 to work, and correct the printed material strip in the direction of travel of the strip into a straight line, preparing for the subsequent steps.

[0032] While the printed strip is being aligned, the die-cutting unit's speed is adjusted by an automatic tracking electronic eye 3, enabling the corresponding cutters in die-cutting unit 12 to precisely cut the printed strip. This ensures the production of precisely patterned products with guaranteed quality and quantity, ensuring high dimensional accuracy. The finished printed strip waste exits die-cutting unit 12 and is finally wound onto a receiving drum 13.

[0033] Due to the wide variety of printing material strips, the width of the material strips themselves and the position of the patterns are different each time. Before the automatic tracking printing and die-cutting device works, the position of the electronic eye 3 needs to be adjusted accordingly. In order to facilitate the adjustment of the position of the electronic eye 3, an adjustment mechanism 4 for adjusting the position along the width direction of the printing material strip is provided on the storage table 121. The electronic eye 3 is installed on the storage table 121 through the adjustment mechanism 4.

[0034] Reference Figure 2 and Figure 3 The adjustment mechanism 4 includes an adjustment bracket 5, a horizontal adjustment component 6 and an angle adjustment component 7. Among them, the adjustment bracket 5 includes a connecting rod 51 and support rods 52 detachably mounted at both ends of the connecting rod 51. The connecting rod 51 and the two support rods 52 constitute a U-shaped frame of the adjustment bracket 5. The cross-sections of the connecting rod 51 and the support rod 52 are both set to rectangular cross-sections, and the detachable connection method between the two is selected as follows: one end of the support rod 52 is fixedly connected to a sleeve 53, and the two ends of the connecting rod 51 are respectively inserted into the sleeve 53 of the support rod 52, and the two are fixedly connected by fasteners; the other end of the support rod 52 is provided with a support foot, which is temporarily fixed to the storage table 121 by fasteners.

[0035] The level adjustment assembly 6 includes a connecting tube 61. The inner diameter of the connecting tube 61 is adapted to the connecting rod 51, so that the connecting tube 61 can be sleeved on the connecting rod 51 and slideably engaged with the connecting rod 51. A jackscrew 62 is threadedly connected to the connecting tube 61, and the connecting tube 61 is fixed to the connecting rod 51 by screwing the jackscrew 62.

[0036] The angle adjustment assembly 7 includes a mounting plate 71 for mounting the electronic eye 3 , an adjusting member 72 rotatably connected to the mounting plate 71 for adjusting the angle of the mounting plate 71 , and a limiting member 73 provided on the adjusting member 72 for limiting the rotation of the mounting plate 71 .

[0037] The adjusting member 72 includes a connecting plate 721 fixed on the connecting tube 61, and an arc-shaped groove is opened on one side of the connecting plate 721, and an adjusting rod 722 is horizontally arranged in the groove. Two bearing seats are rotatably provided on the adjusting rod 722, and the adjusting rod 722 is fixed on the connecting plate 721 through the bearing seats, and the adjusting rod 722 can rotate around its axis; two connecting ears 711 are fixedly connected to the lower end surface of the mounting plate 71, and the two ends of the adjusting rod 722 are respectively fixed to the two connecting ears 711, so that the adjusting rod 722 is fixed to the mounting plate 71, so that the mounting plate 71 can rotate around the axis of the adjusting rod 722, and the electronic eye 3 is fixed on the mounting plate 71, so that the horizontal angle adjustment of the electronic eye 3 is realized, which is convenient for the electronic eye 3 to compare with the printed material pattern.

[0038] The adjusting rod 722 is also fixedly connected to a circular toothed disc 723 distributed radially along the adjusting rod 722. The connecting plate 721 is provided with a clearance groove for the circular toothed disc 723. The limiting member 73 has a folded rod shape and is divided into a force-applying portion 731 and a limiting portion 732 at its turning point. The turning point of the limiting member 73 is a hinge point hinged to the outer wall of the connecting plate 721, and the axis of the hinge point is horizontally arranged. The force-applying portion 731 of the limiting member 73 is arranged in a direction away from the connecting plate 721. The end of the limiting portion 732, away from its hinge point, extends toward the connecting plate 721 to form a clamping platform 733, which can engage with the teeth of the circular toothed disc 723. A tension spring 734 is provided between the limiting portion 732 and the outer wall of the connecting plate 721. One end of the tension spring 734 is fixedly connected to the connecting plate 721, and the other end is fixedly connected to the limiting portion 732. The tension spring 734 applies tension to the limiting portion 732, so that it is always stuck on the teeth of the circular toothed disk 723 in the absence of external force, so as to limit the rotation of the circular toothed disk 723, thereby achieving the fixation of the mounting plate 71, so that the electronic eye 3 can be fixed at a specific angle, and the printing material strip can be corrected so that the printing material strip forms a straight line, ensuring that the output of products with precise patterns can be completed with quality and quantity, and ensuring high dimensional accuracy.
