Description

Technical Field

[0001] The invention relates to the field of die-cutting devices, in particular to a self-adhesive label laser die-cutting device. Background Art

[0002] Self-adhesive labels, also known as self-adhesive labels, instant stickers, post-it notes, or pressure-sensitive paper, are made of a composite material with paper, film, or specialty materials as the front, adhesive coated on the back, and a silicone-coated protective paper as the backing. After printing and die-cutting, they become finished labels. Their convenience, speed, and wide applicability have made them widely used in modern life.

[0003] Existing self-adhesive labels are usually die-cut by laser. However, when using laser die-cutting, the high temperature of the laser beam will form a heat-affected zone on the material. The temperature of this area will be significantly higher than the surrounding area, which will cause the self-adhesive labels on both sides of the cut in this area to warp. However, existing die-cutting devices are unable to fully press the self-adhesive labels to be cut, and cannot prevent the warping on both sides of the cut of the self-adhesive labels without affecting the die-cutting work.

All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] As mentioned in the background technology of this application, research has found that existing self-adhesive labels usually use laser die-cutting when performing die-cutting processing. However, when using laser die-cutting self-adhesive labels, due to the high temperature of the laser beam, a heat-affected zone will be formed on the material. The temperature of this area will be significantly higher than that of the surrounding area, thereby causing the self-adhesive labels on both sides of the cut in this area to warp up. However, the existing die-cutting device cannot fully press the self-adhesive labels to be cut, and cannot avoid the warping of both sides of the cut of the self-adhesive labels without affecting the die-cutting work, which has certain defects.

[0035] In order to solve the above-mentioned defects, the present application discloses a self-adhesive label laser die-cutting device, which can fully press the self-adhesive label to be cut and prevent the two sides of the cut seam of the self-adhesive label from warping without affecting the die-cutting work.

A two-position three-way steering valve 56 is fixedly connected to the top surface of the exhaust box 43, and the two input ends of the two-position three-way steering valve 56 are respectively connected to the two air outlets 55 by a pipe 57.

[0042] In this embodiment, the dust collecting element specifically includes: dust outlets 45 provided on both sides of the bottom end surface of the exhaust gas box 43. The top ends of the dust outlets 45 communicate with the exhaust gas chamber 44. The bottom ends of the dust outlets 45 are provided with threaded openings 46.

[0043] In this embodiment, the laser cutting assembly specifically includes: four third linear guides 4 symmetrically fixed on the inner walls of both sides of the cutting chamber 2, the third linear motors 5 movably connected to the third linear guides 4, the outer sides of the two third linear motors 5 on the same side are commonly fixedly connected to a side plate 6, a through-type stepping screw 7 is fixedly connected between the two side plates 6, and the external movably connected to the through-type stepping screw 7 is a through-type stepping motor 8, one side of the through-type stepping motor 8 is fixedly connected to a fixed plate 9, and the top of the fixed plate 9 is fixedly connected to a rectangular plate 10, the top of the rectangular plate 10 is fixedly connected to a drive motor 11, and the bottom output shaft of the drive motor 11 is fixedly connected to a transmission screw 13, the transmission screw 13 is externally threadedly connected to a lifting support plate 14, and the bottom end of one side of the lifting support plate 14 is fixedly connected to a laser cutter 15, the bottom end of one side of the fixed plate 9 is fixedly connected to a rotating seat 12, and the rotating seat 12 is rotatably connected to the bottom end of the transmission screw 13.

[0044] In this embodiment, a transverse limiting guide rail 18 is fixedly connected to the bottom of the through-type stepping screw 7, and a transverse limiting slider 19 is movably connected to the outside of the transverse limiting guide rail 18. The transverse limiting slider 19 is fixedly connected to the fixed plate 9.

Vertical limit sliders 17 are movably connected to the exterior of the vertical limit rails 16. The vertical limit sliders 17 are fixedly connected to the lift support plate 14. The combination of the vertical limit sliders 17 and the vertical limit rails 16 effectively improves the stability of the vertical movement of the lift support plate 14.

[0046] In this embodiment, the bottom corner of the body 1 is fixedly connected with a support leg 3. The arrangement of the support leg 3 can keep the body 1 away from the erosion of ground moisture.

[0047] The working principle of the present invention is as follows: during use, the cutting support plate 31 is first fed out of the cutting chamber 2 along the guide port 32. Specifically, the first linear motor 29 operates and moves along the first linear guide 28 toward the loading and unloading support platform 33. During this process, the support column 30 on the first linear motor 29 moves accordingly, thereby driving the cutting support plate 31 to follow suit. After the cutting support plate 31 reaches the designated position above the loading and unloading support platform 33 according to a preset procedure, the worker places the self-adhesive label to be die-cut into the lifting groove 35. It should be noted that the size of the self-adhesive label matches the lifting groove 35, so that the lifting groove 35 can restrain the inserted self-adhesive label, and at this time, the L-shaped plate 34 does not contact the cutting support plate 31. Then, the first linear motor 29 operates again and moves along the first linear guide 28 into the cutting chamber 2, thereby driving the cutting support plate 31 and the self-adhesive label to follow suit. After the cutting support plate 31 reaches the designated position according to the preset procedure, the first pressing plate 24 of the position-limiting die pressing mechanism is located directly above the cutting support plate 31. At this time, the cylinder 22 operates to retract the output shaft, causing the second pressing plate 26 to descend synchronously with the first pressing plate 24 and the strip plate 23. During the process, the first pressing plate 24 is pressed into the lifting groove 35 to press the self-adhesive label, while the second pressing plate 26 is located outside the cutting support plate 31.

[0048] Next, the laser cutting assembly operates to perform the first die-cutting of the self-adhesive label. During this process, the laser cutter 15 performs die-cutting in sequence along the cutting track (i.e., the transverse groove 25) reserved by the first pressure plate 24. After the first die-cutting is completed, the first pressure plate 24 is raised, and the second pressure plate 26 is transferred to the top of the cutting support plate 31 via the second linear guide 20 and the second linear motor 21. The second pressure plate 26 is then pressed into the lifting groove 35, and the laser cutter 15 performs the second die-cutting along the cutting track (i.e., the longitudinal groove 27) reserved by the second pressure plate 26. This die-cutting method not only can fully press and consolidate the self-adhesive label to be cut, improving stability, but also can prevent the two sides of the cut seam of the self-adhesive label from warping without affecting the die-cutting work, thereby improving the die-cutting effect. It should be noted that both the first pressure plate 24 and the second pressure plate 26 are made of quartz, a material with high light transmittance and chemical stability. Quartz also has very low absorption of laser beams and does not affect the cutting effect of the laser cutter 15. The laser cutter 15 can perform three-axis position adjustment during use. Specifically, the through-type stepper motor 8 runs along the through-type stepper screw 7 to move left and right, thereby driving the laser cutter 15 to move left and right. The third linear motor 5 runs along the third linear guide 4 to move forward and backward, thereby driving the laser cutter 15 to move forward and backward. The drive motor 11 runs to drive the transmission screw 13 to rotate, so that the lifting support plate 14 moves up and down along the transmission screw 13, thereby driving the laser cutter 15 to move up and down.

[0049] After the self-adhesive label is die-cut, the first linear motor 29 runs along the first linear guide rail 28 to send the cutting support plate 31 outward until the cutting support plate 31 is completely docked with the L-shaped plate 34 on the loading and unloading support platform 33. Specifically, one end of the L-shaped plate 34 extends into the lifting groove 35 from the slot 39. Due to the inclined surface effect generated between the first inclined surface 40 and the second inclined surface 41, the lifting plate 36 is lifted by the L-shaped plate 34 and rises along the lifting groove 35. During the process, the limit head 37 and the limit groove 38 undergo relative displacement, and the lifting plate 36 also sends the self-adhesive label with die-cutting completed thereon out of the lifting groove 35, making it convenient for the staff to take it. After the staff takes away the self-adhesive label, the first linear motor 29 runs along the first linear guide rail 28 to move the cutting support plate 31 a certain distance toward the cutting chamber 2 according to a preset program. At this time, the cutting support plate 31 is separated from the L-shaped plate 34, and the lifting plate 36 falls to the bottom of the lifting slot 35 again under the action of its own gravity to wait for the next self-adhesive label.

[0050] In addition, a certain amount of smoke is generated during the laser die-cutting process. This smoke contains large particles of impurities. If it is directly discharged without filtering, it will cause pollution. For this reason, the present application filters this smoke through the exhaust gas treatment component set up. Specifically, the exhaust fan 42 runs to extract the air containing smoke from the cutting chamber 2, and then sends the smoke into the exhaust gas chamber 44 through the air inlet 54. At this time, the left pipe 57 of the two-position three-way steering valve 56 is conductive, while the right pipe 57 is not conductive. Therefore, after passing through the filter 53 of the rotating frame 52, the smoke enters the left pipe 57 along the left air outlet 55, and is finally discharged through the outlet pipe 58 of the two-position three-way steering valve 56. After a period of use, a large amount of impurities adhere to the right working surface of the filter 53, which will affect the subsequent filtering effect. To this end, the stepper motor 51 drives the cylinder 50 in the rotating groove 49 to rotate clockwise 90 degrees, which in turn causes the rotating frame 52 to rotate 90 degrees accordingly. When the rotating frame 52 rotates and collides with the rotating support platform 48, the vibration generated by the collision will shake off some impurities attached to the filter 53. Under the action of their own gravity, the fallen impurities fall along the dust outlet 45 into the dust collection barrel 47. At the same time, the two-position three-way diverter valve 56 switches its working state, making the left duct 57 non-conductive and the right duct 57 conductive. The left working surface of the filter 53 directly faces the smoke air. When the smoke air passes through the filter 53, the airflow will flush away some impurities attached to the right working surface of the filter 53 and drop them. Most of these impurities fall into the cylinder 50, and a small amount of lighter impurities are carried away by the airflow, which has little impact on the overall filtering effect, thereby completing the self-cleaning of the right working surface of the filter 53. When the left working surface of the filter 53 becomes dirty, it can be switched to the initial state for filtering. By using the two working surfaces of the filter 53 alternately, the difficulty of cleaning the filter 53 is effectively reduced, making it easier to use. For impurities that fall into the cylinder 50, the operator only needs to unscrew the cylinder 50 from the threaded opening 46 to clean it.

[0051] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.

[0052] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
