Description

Technical Field

[0001] This invention relates to the field of label manufacturing technology, specifically to a self-adhesive laser flexible cutting mechanism for irregularly shaped labels. Background Technology

[0002] In the production process of modern packaging factories, product labels are an indispensable part of product packaging. Most labels, as referred to in the printing industry, are printed materials used to identify relevant information about products, and most have adhesive backing. However, some labels are printed without adhesive and can still be called labels. Labels with adhesive are commonly known as "self-adhesive labels." Self-adhesive labels are label materials with special adhesive, also called self-adhesive labels, instant labels, pressure-sensitive paper, etc. They are composite materials with paper, film, or special materials as the face stock, adhesive on the back, and silicone-coated release paper as the backing. After printing and die-cutting, they become finished labels. Due to their convenience, speed, and wide applicability, they are widely used in modern life. Currently, laser die-cutting is commonly used for self-adhesive labels.

[0003] Publication No. CN209125136U discloses a label cutting laser device that cuts labels using a laser. It can control different label types via software, resulting in higher cutting efficiency. Furthermore, the laser device can be adjusted in position using a screw and an adjusting handle to cut different label types, making it more convenient to use. The winding or unwinding device is also equipped with an encoding device to read the film speed and provide real-time feedback to the control system. Finally, a protective cover is provided to further improve the safety of the equipment and protect the operator. However, this patent still has the following problems in actual use: Although this label cutting laser equipment can cut labels with a laser and can control different label types through control software, when cutting self-adhesive labels, which are usually composite structures (face material + adhesive layer + silicone backing paper), the laser power needs to be precisely controlled. The organic fumes (which may contain formaldehyde and benzene compounds) generated by the pyrolysis of the adhesive layer cannot be quickly discharged, thus affecting the laser cutting effect. At the same time, molten material is generated during laser cutting. Existing technology uses auxiliary gas (such as compressed air) to blow away the molten material to reduce carbonization. However, as the laser device is adjusted, the blowing angle of its blowing port changes, thus affecting the blowing effect.

[0004] Therefore, a flexible laser cutting mechanism for irregularly shaped labels is proposed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a flexible laser cutting mechanism for irregularly shaped labels, to solve the problems mentioned in the background art. In the cutting of self-adhesive labels, which are typically composite structures (face material + adhesive layer + silicone backing paper), the laser power needs precise control. The organic fumes (possibly containing formaldehyde and benzene compounds) generated by the pyrolysis of the adhesive layer cannot be quickly discharged, thus affecting the laser cutting effect. Simultaneously, molten material is generated during laser cutting. While existing technologies use auxiliary gases (such as compressed air) to blow away the molten material to reduce carbonization, the blowing angle of the air nozzle changes with the adjustment of the laser device, thus affecting the blowing effect.

The tensioning sliding rod is fixedly installed inside the limiting bracket on the other side.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This self-adhesive laser flexible cutting mechanism for irregularly shaped labels, through the adjustment motor driving the first bevel gear transmission assembly and the adjustment threaded rod to rotate, causes the adjustment threaded sleeve to move on the outside of the adjustment threaded rod while simultaneously rotating the adjustment rotating rod, thereby realizing the rotation of the automatic adjustment bracket. This facilitates the calibration of the air blowing angle of the air blowing device, ensuring that the air blowing angle of the air blowing device is directly aligned with the laser focus point of the laser cutting device, guaranteeing that residue is directly blown away from the cutting area. The electric telescopic rod drives the first gear protective cover and the bottom rotating disk to move up and down, thereby achieving height adjustment of the laser cutting device, facilitating the adjustment of the laser focus point to adapt to the cutting of irregularly shaped labels. The second rotating motor drives the rotating dust suction roller to rotate, using the air suction generated by the vacuum cleaner and its rotation to absorb the fumes and residue generated by laser cutting, reducing carbonization. Simultaneously, the elastic force of the clamping spring causes the clamping sliding sleeve to move the clamping sliding plate and clamping roller, using the clamping roller to press the surface of the label, preventing the suction force generated by the rotating dust suction roller from causing label wrinkles or lifting. The specific details are as follows: 1. By setting up an air-blowing and dust-collecting mechanism, not only can the cutting protective cover protect irregularly shaped self-adhesive labels during laser cutting, but also, by adjusting the motor to drive the first bevel gear transmission assembly and the adjusting threaded rod to rotate, the adjusting threaded sleeve moves outside the adjusting threaded rod, thereby rotating the adjusting rod and automatically adjusting the bracket. This facilitates the calibration of the air-blowing angle of the air-blowing equipment, ensuring that the air-blowing angle is directly aligned with the laser focus point of the laser cutting equipment, guaranteeing that residue is directly blown away from the cutting area. Simultaneously, when cutting irregularly shaped labels, the laser focus point of the laser cutting equipment needs to be adjusted. An electric telescopic rod drives the first gear protective cover and the bottom rotating disk to move up and down, thereby adjusting the height of the laser cutting equipment to facilitate the adjustment of the laser focus point and adapt to the cutting of irregularly shaped labels. When the bottom rotating disk moves up and down, the angle of the automatically adjusting bracket is adjusted under the action of the adjusting rotating rod, ensuring that the air-blowing angle of the air-blowing equipment is automatically aligned according to the laser focus point adjustment, improving the cutting effect of irregularly shaped labels. At the same time, the first rotating motor is started, driving the first rotating main gear to rotate, utilizing the meshing connection between the first rotating main gear and the first rotating secondary gear. Its features allow the first rotation, driven by gears, to rotate the bottom rotating disk and the air blowing device, enabling switching between the two air blowing devices. This avoids overheating and damage to the air blowing equipment, extending its service life. The second rotation motor then drives the rotating suction roller, using the airflow generated by the vacuum cleaner to absorb the fumes and residue from laser cutting, reducing carbonization. Simultaneously, the spring force of the pressure spring causes the pressure sliding sleeve to move the pressure sliding plate and pressure roller, pressing the label surface firmly and preventing wrinkles caused by the suction of the rotating suction roller. Or the phenomenon of lifting, at the same time, by reversing the two second rotating motors, the two rotating dust suction rollers are rotated in opposite directions, which can smooth and remove wrinkles on the surface of the cutting area, thus affecting the accuracy of label cutting. The translation motor drives the translation threaded rod to rotate, so that the translation threaded sleeve drives the longitudinal support to move horizontally. At the same time, the longitudinal motor drives the longitudinal threaded rod to rotate, so that the longitudinal threaded sleeve drives the laser cutting equipment to move longitudinally, which facilitates the adjustment of the position of the laser cutting equipment, thereby cutting irregularly shaped labels. Harmful gases can be introduced into the purification equipment for treatment to avoid harmful gases from escaping and causing air pollution. 2. By setting up a feeding and winding mechanism, the unfolding motor can drive the second bevel gear transmission assembly and the unfolding threaded rod to rotate, causing the unfolding threaded sleeve to drive the inner support plate to unfold, thus supporting the wound label. At the same time, the third rotating motor is started to drive the second rotating main gear to rotate. Utilizing the meshing connection between the second rotating main gear and the second rotating driven gear, the second rotating driven gear drives the rotating sleeve and the unfolding disc to rotate. The unfolding disc drives the inner support plate to rotate, facilitating the feeding and winding of the label. The label is limited and supported by the limiting roller inside the limiting bracket. Simultaneously, rotating the tension knob drives the third bevel gear transmission assembly and the tensioning threaded rod to rotate, causing the tensioning threaded sleeve to drive the tensioning roller to move up and down. By adjusting the height of the tensioning roller, the tension of the label can be adjusted, improving the efficiency of label cutting. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-4 , Figure 7This invention provides a technical solution: a flexible laser cutting mechanism for irregularly shaped labels, comprising an air blowing and dust suction mechanism 1, and a cutting protective cover 101 installed on the outside of the air blowing and dust suction mechanism 1. A feeding and winding mechanism 2 is provided on the outside of the air blowing and dust suction mechanism 1, and limit brackets 218 are symmetrically installed on the top of the feeding and winding mechanism 2. The air blowing and dust suction mechanism 1 includes a longitudinal threaded sleeve 112, a top rotating ring 113 rotatably connected to the bottom of the longitudinal threaded sleeve 112, and an automatic adjustment bracket 114 symmetrically rotatably connected to the bottom of the top rotating ring 113. An adjusting motor 115 is fixedly mounted on the outer side of the adjusting bracket 114. A first bevel gear transmission assembly 116 is fixedly connected to the output end of the adjusting motor 115. An adjusting threaded rod 117 is fixedly mounted on one side of the first bevel gear transmission assembly 116. An adjusting threaded sleeve 118 is threadedly connected to the outer side of the adjusting threaded rod 117. An adjusting rotating rod 119 is rotatably connected to the outer side of the adjusting threaded sleeve 118. An air blowing device 120 is fixedly mounted at the end of the automatic adjusting bracket 114. A cutting protective cover 101 is used for laser cutting protection of irregularly shaped self-adhesive labels. Simultaneously, by adjusting the motor 115, the first bevel gear transmission assembly 116 and the adjusting threaded rod 117 are driven to rotate. This causes the adjusting threaded sleeve 118 to move outside the adjusting threaded rod 117, thereby rotating the adjusting rotating rod 119. This achieves the rotation of the automatic adjusting bracket 114, facilitating the calibration of the blowing angle of the air blowing device 120. This ensures that the blowing angle of the air blowing device 120 is directly aligned with the laser focus point of the laser cutting device 127, guaranteeing that residue is directly blown away from the cutting area. Furthermore, when cutting irregularly shaped labels, it is necessary to adjust the laser focus of the laser cutting device 127. The laser focusing point is adjusted by using an electric telescopic rod 121 to drive the first gear protective cover 122 and the bottom rotating disk 126 to move up and down, thereby realizing the height adjustment of the laser cutting equipment 127. This facilitates the adjustment of the laser focusing point and adapts to the cutting of irregularly shaped labels. When the bottom rotating disk 126 moves up and down, the angle of the automatic adjustment bracket 114 is adjusted by the adjustment rotating rod 119, so that the blowing angle of the air blowing device 120 can be automatically aligned according to the laser focusing point adjustment of the laser cutting equipment 127, thereby improving the cutting effect of irregularly shaped labels.

[0020] Please see Figure 4An electric telescopic rod 121 is fixedly installed at the bottom center of the longitudinal threaded sleeve 112. A first gear protective cover 122 is fixedly installed at the bottom of the electric telescopic rod 121. A first rotating motor 123 is fixedly installed on one side of the top of the first gear protective cover 122. A first rotating main gear 124 is fixedly connected to the output end of the first rotating motor 123. A first rotating driven gear 125 is meshed with one side of the first rotating main gear 124. A bottom rotating disk 126 is fixedly installed at the bottom of the first rotating driven gear 125. The bottom rotating disk 126 is connected to the adjusting rotating... The moving rod 119 is rotatably connected, and the laser cutting device 127 is fixedly installed at the bottom center of the bottom rotating disk 126. The first rotating motor 123 is started to drive the first rotating main gear 124 to rotate. Utilizing the meshing connection between the first rotating main gear 124 and the first rotating driven gear 125, the first rotating driven gear 125 drives the bottom rotating disk 126 and the air blowing device 120 to rotate, which can switch the air blowing between the two air blowing devices 120, avoid the phenomenon of overheating and damage to the air blowing device 120, and improve the service life of the air blowing device 120.

[0021] Please see Figures 2-6A second rotating motor 128 is symmetrically installed on the outside of the cutting protective cover 101. A rotating dust-collecting roller 129 is fixedly connected to the output end of the second rotating motor 128. A rotating tube 130 is rotatably connected to the end of the rotating dust-collecting roller 129. The rotating tube 130 is fixedly installed inside the cutting protective cover 101. A connecting tube 131 is fixedly connected to the end of the rotating tube 130. A vacuum cleaner 132 is fixedly installed at the end of the connecting tube 131. Several clamping brackets 133 are fixedly installed at both ends of the rotating dust-collecting roller 129. A clamping sliding rod 134 is fixedly installed inside the clamping bracket 133. A clamping sliding sleeve 135 is slidably connected to the outside of the clamping sliding rod 134. A clamping spring 136 is fixedly connected to one side of the clamping sliding sleeve 135. A pressing sliding plate 137 is fixedly installed on the outer side of the tight sliding sleeve 135. A pressing roller 138 is rotatably connected between the two pressing sliding plates 137. A support block 102 is fixedly installed on the inner bottom side of the cutting protective cover 101. A translation bracket 103 is fixedly installed on the inner top side of the cutting protective cover 101. A translation motor 104 is fixedly installed at the end of the translation bracket 103. A translation threaded rod 105 is fixedly connected to the output end of the translation motor 104. A translation threaded sleeve 106 is threadedly connected to the outer side of the translation threaded rod 105.

Translation sliding sleeves 108 are slidably connected to the outer sides of both translation sliding rods 107. The bottoms of the translation sliding sleeves 108 and the translation threaded sleeves 106 are connected to each other. A longitudinal support 109 is fixedly installed, and a longitudinal motor 110 is fixedly installed at the end of the longitudinal support 109. A longitudinal threaded rod 111 is fixedly connected to the output end of the longitudinal motor 110. The longitudinal threaded rod 111 is threadedly connected to the longitudinal threaded sleeve 112. When the second rotating motor 128 is started, it drives the rotating dust-collecting roller 129 to rotate. The vacuum cleaner 132 generates airflow and absorbs the fumes and residues generated by laser cutting through rotation, reducing carbonization. At the same time, the elastic force of the pressure spring 136 causes the pressure sliding sleeve 135 to move the pressure sliding plate 137 and the pressure roller 138. The pressure roller 138 presses the surface of the label, preventing the suction generated by the rotating dust-collecting roller 129 from causing the label to wrinkle or lift. The phenomenon is that by simultaneously starting two second rotating motors 128 in reverse, the two rotating dust-collecting rollers 129 rotate in opposite directions, which can smooth and remove wrinkles from the surface of the cutting area, thus affecting the accuracy of label cutting. The translation motor 104 drives the translation threaded rod 105 to rotate, which causes the translation threaded sleeve 106 to drive the longitudinal support 109 to move horizontally. At the same time, the longitudinal motor 110 drives the longitudinal threaded rod 111 to rotate, which causes the longitudinal threaded sleeve 112 to drive the laser cutting equipment 127 to move longitudinally, which facilitates the adjustment of the position of the laser cutting equipment 127, thereby cutting irregularly shaped labels. The surface of the rotating dust-collecting roller 129 is provided with several dust-collecting holes. The suction force generated by the vacuum cleaner 132 allows the smoke and residue to be absorbed through the dust-collecting holes.

[0022] Please see Figure 1 , Figures 7-10 , Figure 12 The feeding and winding mechanism 2 includes a mounting base plate 201. A cutting guard 101 is fixedly installed at the top center of the mounting base plate 201.

Second gear guards 204 are fixedly installed on the outer sides of both feeding brackets 202 and winding brackets 203. A third rotating motor 205 is fixedly installed on one side of the top of the second gear guard 204. A second rotating main gear 206 is fixedly connected to the output end of the third rotating motor 205. A second rotating driven gear 207 is meshed with the bottom teeth of the second rotating main gear 206. A rotating sleeve 208 is fixedly installed inside the second rotating driven gear 207. An unfolding disc 209 is fixedly installed on the outer side of the rotating sleeve 208. An unfolding motor 210 is fixedly installed on the side of the rotating sleeve 208 away from the unfolding disc 209. A second bevel gear transmission assembly 211 is fixedly connected to the output end of the unfolding motor 210. Unfolding threaded rods 212 are fixedly connected around the second bevel gear transmission assembly 211. The outer side of the unfolding threaded rod 212 is threadedly connected to an unfolding threaded sleeve 213. An inner support plate 214 is fixedly installed on the outer side of the unfolding threaded sleeve 213. An inner support rotating rod 215 is symmetrically rotatably connected to the inner side of the inner support plate 214. A sliding sleeve 216 is rotatably connected to the end of the inner support rotating rod 215. A sliding fixed rod 217 is slidably connected inside the sliding sleeve 216. The sliding fixed rod 217 is fixedly installed at the outer center position of the unfolding disc 209. The unfolding motor 210 drives the second bevel gear transmission assembly 2. Rotation of the unfolding threaded rod 212 causes the unfolding threaded sleeve 213 to unfold the inner support plate 214, which can support the rolled-up label. At the same time, the third rotating motor 205 is started to drive the second rotating main gear 206 to rotate. Taking advantage of the meshing connection between the second rotating main gear 206 and the second rotating driven gear 207, the second rotating driven gear 207 drives the rotating sleeve 208 and the unfolding disc 209 to rotate. The unfolding disc 209 drives the inner support plate 214 to rotate, which facilitates the feeding and winding of the label.

[0023] Please see Figure 11Limiting brackets 218 are symmetrically installed on both sides of the top of the mounting base plate 201.

The part is rotatably connected to a tensioning sliding sleeve 225, and a tensioning sliding rod 226 is slidably connected inside the tensioning sliding sleeve 225. The tensioning sliding rod 226 is fixedly installed inside the limit bracket 218 on the other side. The label is limited and supported by the limit roller 219 inside the limit bracket 218. At the same time, rotating the tensioning knob 220 drives the third bevel gear transmission assembly 221 and the tensioning threaded rod 222 to rotate, so that the tensioning threaded sleeve 223 drives the tensioning roller 224 to move up and down. By adjusting the height of the tensioning roller 224, the tension of the label is adjusted, thereby improving the efficiency of label cutting.

[0024] Working principle: Before using this self-adhesive laser flexible cutting mechanism for irregularly shaped labels, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 11 As shown, firstly, the unfolding motor 210 drives the second bevel gear transmission assembly 211 and the unfolding threaded rod 212 to rotate, causing the unfolding threaded sleeve 213 to drive the inner support plate 214 to unfold, which can support the rolled-up label. At the same time, the third rotating motor 205 is started to drive the second rotating main gear 206 to rotate. Taking advantage of the meshing connection between the second rotating main gear 206 and the second rotating driven gear 207, the second rotating driven gear 207 drives the rotating sleeve 208 and the unfolding disk 209 to rotate. The unfolding disk 209 drives the inner support plate 214 to rotate, which facilitates the feeding and winding of the label. The label is limited and supported by the limiting roller 219 inside the limiting bracket 218. At the same time, rotating the tension knob 220 drives the third bevel gear transmission assembly 221 and the tensioning threaded rod 222 to rotate, causing the tensioning threaded sleeve 223 to drive the tensioning roller 224 to move up and down. By adjusting the height of the tensioning roller 224, the tension of the label is adjusted, thereby improving the efficiency of label cutting.

[0025] Secondly, the cutting protective cover 101 is used to protect the irregularly shaped self-adhesive labels from laser cutting. Simultaneously, the adjusting motor 115 drives the first bevel gear transmission assembly 116 and the adjusting threaded rod 117 to rotate. This causes the adjusting threaded sleeve 118 to move outside the adjusting threaded rod 117, simultaneously rotating the adjusting rotating rod 119. This, in turn, rotates the automatic adjusting bracket 114, facilitating the calibration of the blowing angle of the air blowing device 120. This ensures the blowing angle of the air blowing device 120 is directly aligned with the laser focus point of the laser cutting device 127, guaranteeing that residue is directly blown away from the cutting area. Furthermore, when cutting irregularly shaped labels, the laser focus point of the laser cutting device 127 needs adjustment. The electric telescopic rod 121 drives the first gear protective cover 122 and the bottom rotating disk 126 to move up and down, thereby enabling the laser cutting device 127 to move. The height adjustment facilitates the adjustment of the laser focus point, thus adapting to the cutting of irregularly shaped labels. When the bottom rotating disk 126 moves up and down, the angle of the automatic adjustment bracket 114 is adjusted under the action of the adjustment rotating rod 119, so that the blowing angle of the air blowing device 120 can be automatically aligned according to the laser focus point adjustment of the laser cutting device 127, improving the cutting effect of irregularly shaped labels. At the same time, the first rotating motor 123 is started to drive the first rotating main gear 124 to rotate. Utilizing the meshing connection between the first rotating main gear 124 and the first rotating driven gear 125, the first rotating driven gear 125 drives the bottom rotating disk 126 and the air blowing device 120 to rotate, which can switch the air blowing between the two air blowing devices 120, avoiding the phenomenon of overheating and damage to the air blowing device 120, and improving the service life of the air blowing device 120.

[0026] Finally, the second rotating motor 128 is activated to drive the rotating suction roller 129 to rotate. The vacuum cleaner 132 generates airflow, which, through rotation, absorbs the fumes and residue generated by laser cutting, reducing carbonization. Simultaneously, the spring force of the pressure spring 136 causes the pressure sliding sleeve 135 to move the pressure sliding plate 137 and the pressure roller 138. The pressure roller 138 presses firmly against the label surface, preventing the suction force generated by the rotating suction roller 129 from causing the label to wrinkle or lift. At the same time, the two second rotating motors are activated in reverse. The rotating motor 128 enables the two rotating dust suction rollers 129 to rotate in opposite directions, which can smooth and remove wrinkles from the surface of the cutting area, thus affecting the accuracy of label cutting. The translation motor 104 drives the translation threaded rod 105 to rotate, which causes the translation threaded sleeve 106 to drive the longitudinal support 109 to move horizontally. At the same time, the longitudinal motor 110 drives the longitudinal threaded rod 111 to rotate, which causes the longitudinal threaded sleeve 112 to drive the laser cutting equipment 127 to move longitudinally, which facilitates the adjustment of the position of the laser cutting equipment 127, thereby cutting irregularly shaped labels.
