Description

Technical Field

[0002] Self-adhesive labels are a type of label material with special glue, also known as self-sticking labels, instant stickers, pressure-sensitive papers, etc. They are a composite material with a paper, film, or special material as the fabric, an adhesive coated on the back, and a silicone-coated protective paper as the backing paper. After processes such as printing and die-cutting, they become finished labels, and due to their convenience, speed, wide applicability, etc., they are widely used in modern life.

[0023] As mentioned in the background art of this application, through research, it is found that when existing self-adhesive labels are die-cut, laser die-cutting is usually used. However, when using laser die-cutting for self-adhesive labels, due to the high temperature effect of the laser beam, a heat-affected zone will be formed on the material, and the temperature in this area will be significantly higher than the surrounding area. As a result, the self-adhesive labels on both sides of the cut seam in this area will warp. However, the existing die-cutting devices cannot comprehensively press and fix the self-adhesive labels to be cut, and cannot avoid the warping of both sides of the cut seam of the self-adhesive labels without affecting the die-cutting work, which has certain defects.

[0035] In this embodiment, legs 3 are fixedly connected to the corner positions of the bottom end surface of the machine body 1. The setting of the legs 3 can keep the machine body 1 away from the erosion of ground moisture.

[0036] The working principle of the present invention is as follows: When in use, first, the cutting support plate 31 is sent out of the cutting cavity 2 along the material guiding port 32. Specifically, the first linear motor 29 operates and moves along the first linear guide rail 28 towards the loading and unloading support table 33. During this process, the pillar 30 on the first linear motor 29 moves along with it, thereby driving the cutting support plate 31 to move along with it. After the cutting support plate 31 reaches the designated position above the loading and unloading support table 33 according to the preset program, the staff places the self-adhesive label to be die-cut in the lifting groove 35. It should be noted that the self-adhesive label matches the size of the lifting groove 35, so that the lifting groove 35 can limit the placed self-adhesive label, and at this time, the L-shaped plate 34 is not in contact with the cutting support plate 31. Then, the first linear motor 29 operates again and moves towards the inside of the cutting cavity 2 along the first linear guide rail 28, thereby driving the cutting support plate 31 together with the self-adhesive label to move along with it. After the cutting support plate 31 reaches the designated position according to the preset program, the first pressing plate 24 of the limit pressing die mechanism is just located directly above the cutting support plate 31. At this time, the cylinder 22 operates to retract the output shaft, so that the second pressing plate 26 and the first pressing plate 24 and the strip plate 23 descend synchronously. During this process, the first pressing plate 24 just presses into the lifting groove 35 to press and fix the self-adhesive label, and the second pressing plate 26 is located outside the cutting support plate 31.

[0037] Immediately afterwards, the laser cutting assembly operates to perform the first die-cutting on the self-adhesive label. During this process, the laser cutter 15 sequentially performs die-cutting along the cutting track reserved by the first pressing plate 24 (i.e., the transverse cutting groove 25). After the first die-cutting is completed, the first pressing plate 24 is raised, and then the second pressing plate 26 is transferred to directly above the cutting support plate 31 through the second linear guide rail 20 and the second linear motor 21. Subsequently, the second pressing plate 26 is pressed in the lifting groove 35, and the laser cutter 15 performs the second die-cutting along the cutting track reserved by the second pressing plate 26 (i.e., the longitudinal cutting groove 27). This die-cutting method can not only comprehensively press and fix the self-adhesive label to be cut, improving stability, but also avoid the two sides of the cut seam of the self-adhesive label from warping up on the premise of not affecting the die-cutting work, improving the die-cutting effect. It should be noted that both the first pressing plate 24 and the second pressing plate 26 are made of quartz. Quartz is a material with high light transmittance and chemical stability, and has a very low absorption of laser beams, which does not affect the cutting effect of the laser cutter 15. The laser cutter 15 can be adjusted in three-axis positions during use. Specifically, the through-type stepping motor 8 operates and moves left and right along the through-type lead screw 7, thereby driving the laser cutter 15 to move left and right. The third linear motor 5 operates and moves back and forth along the third linear guide rail 4, thereby driving the laser cutter 15 to move back and forth. The driving motor 11 operates to drive the transmission lead screw 13 to rotate, so that the lifting support plate 14 moves up and down along the transmission lead screw 13, thereby driving the laser cutter 15 to move up and down.

[0038] After the die-cutting of the self-adhesive label is completed, the first linear motor 29 operates to send the cutting support plate 31 outwards along the first linear guide rail 28 until the cutting support plate 31 is completely butted against the L-shaped plate 34 on the loading and unloading support table 33. Specifically, one end of the L-shaped plate 34 extends into the lifting groove 35 from the notch 39. Due to the inclined plane action generated between the first inclined plane 40 and the second inclined plane 41, the lifting plate 36 is lifted by the L-shaped plate 34 and rises along the lifting groove 35. During this process, the limiting head 37 and the limiting groove 38 have relative displacement, and the self-adhesive label that has been die-cut on the lifting plate 36 is also sent out of the lifting groove 35, facilitating the staff to take it. After the staff takes away the self-adhesive label, the first linear motor 29 operates to move the cutting support plate 31 a certain distance towards the cutting cavity 2 along the first linear guide rail 28 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 back to the bottom of the lifting groove 35 under its own gravity to wait for receiving the next self-adhesive label.

[0039] In addition, a certain amount of smoke will be generated during the laser die-cutting process. These smoke contain large particles of impurities. If they are directly discharged without filtering, it will cause pollution. For this reason, the present application filters these smoke through the exhaust gas treatment component set up, specifically: the exhaust fan 42 runs to extract the air containing smoke in 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 connected, while the right pipe 57 is not connected. Therefore, after passing through the filter screen 53 of the rotating frame 52, the smoke enters the left pipe 57 along the left air outlet 55, and finally is 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 are attached to the right working surface of the filter screen 53, which will affect the subsequent filtering effect. To this end, the stepper motor 51 drives the cylinder 50 in the rotating slot 49 to rotate clockwise by 90 degrees, and then the rotating frame 52 rotates 90 degrees. When the rotating frame 52 rotates and collides with the rotating support platform 48, the vibration generated by the collision will shake off some of the impurities attached to the filter 53, and the impurities that fall down will fall into the dust collection cylinder 47 along the dust outlet 45 under the action of their own gravity. At the same time, the two-position three-way steering valve 56 switches the working state, so that the left pipe 57 is not conductive, while the right pipe 57 is conductive, and 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 of the impurities attached to the right working surface of the filter 53 and let them fall. Most of these impurities fall into the cylinder 50, and a small number of lighter impurities are taken away by the airflow, which has little effect 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 is 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, and it is convenient to use. For impurities falling into the cylinder 50, the staff only needs to unscrew the cylinder 50 from the threaded opening 46 to clean it.

[0040] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
