Description

Technical Field

[0001] The present invention relates to the technical field of die-cutting machines. More specifically, the present invention relates to a die-cutting device with an anti-adhesion function. Background Art

[0002] Die-cutting machines are mainly used for die-cutting self-adhesive labels, EVA, double-sided tape, electronics, mobile phone pads, etc. When die-cutting self-adhesive labels attached with sponges, due to the relatively thick sponges, the friction area between the die-cutting knife and the self-adhesive label becomes larger after the die-cutting knife cuts into the self-adhesive label. As a result, when the die-cutting knife is lifted, it will drive the self-adhesive label to move upward together through friction, which causes the self-adhesive label to shake greatly, resulting in the deviation of the self-adhesive label and the warping of the die-cut self-adhesive label. At the same time, when replacing the die-cutting knife in the existing equipment, it is necessary to screw out the fixing bolts one by one and then perform the replacement operation, and the operation process is cumbersome and the efficiency is low.

[0040] The auxiliary unit includes a first connecting block 2024, a linkage rod 2025, a third elastic telescopic rod 2027, a fourth elastic telescopic rod 2028 and a second connecting block 2029; a first connecting block 2024 is welded to the lower left and lower right parts of the support plate 2015; two linkage rods 2025 are slidably connected between the two first connecting blocks 2024; the receiving plate 2026 slides between the two linkage rods 2025; a third elastic telescopic rod 2027 is fixedly connected to the front and rear sides of each first connecting block 2024; the telescopic ends of the four third elastic telescopic rods 2027 are respectively fixedly connected to the adjacent linkage rods 2025; two fourth elastic telescopic rods 2028 are fixedly connected to the opposite sides of the two first connecting blocks 2024; the telescopic ends of the four fourth elastic telescopic rods 2028 are fixedly connected to a second connecting block 2029; the four second connecting blocks 2029 all slide with the receiving plate 2026.

[0041] The rotating unit includes a motor 2030, a first spur gear 2031 and a second spur gear 2032; the motor 2030 is fixedly connected to both the left side and the right side of the first linkage 2023; the output shafts of the two motors 2030 are each fixedly connected with a first spur gear 2031; a second spur gear 2032 is fixedly connected to both the left outer part and the right outer part of the first round rod 2014; the two second spur gears 2032 are respectively meshed with the adjacent first spur gears 2031.

[0042] During the preparation work, the workpiece to be cut 4 is fixed in the external winding and conveying mechanism, so that the lower side of the workpiece to be cut 4 is in contact with the upper sides of the first support frame 2 and the support plate 2015. Then, the first telescopic cylinder 202 drives the linkage plate 203 to move downward. The linkage plate 203 drives the zero below it to move downward, so that the pressing block 206 moves downward to contact the upper side of the workpiece to be cut 4. The linkage plate 203 continues to move downward, while the pressing block 206 is blocked by the workpiece to be cut 4 and cannot continue to move. As a result, the linkage plate 203 moves downward relative to the pressing block 206, and compresses the first elastic telescopic rod 205. The linkage plate 203 drives the cutting knife 204 to move downward to cut the workpiece to be cut 4. Then, the first telescopic cylinder 202 drives the linkage plate 203 to move upward to the original position. The linkage plate 203 drives the cutting knife 204 to gradually move away from the cutting opening of the workpiece to be cut 4. During this process, the first elastic telescopic rod 205 gradually rebounds, and the pressing block 206 keeps pressing the workpiece to be cut 4 tightly. When the cutting knife 204 completely disengages from the workpiece to be cut 4, the first elastic telescopic rod 205 rebounds to its original state. Then, the linkage plate 203 drives the first elastic telescopic rod 205 to move upward, and the first elastic telescopic rod 205 drives the pressing block 206 to move back to the original position, completing the cutting operation. Then, the external winding and conveying mechanism drives the workpiece to be cut 4 to move to the right, and the above operation is repeated to cut the next position of the workpiece to be cut 4. During use, when the cutting knife 204 disengages from the workpiece to be cut 4 after cutting, the pressing block 206 presses the workpiece to be cut 4 tightly, avoiding the phenomenon that the cutting knife 204 drives the workpiece to be cut 4 to move upward together due to the deep cut, thereby avoiding the shaking phenomenon of the workpiece to be cut 4 and improving the stability of the die-cutting operation.

[0043] During the cutting process, the linkage plate 203 will also drive the first linkage frame 2023 to move downward. The first linkage frame 2023 squeezes the airbag 2018, so that the air in the airbag 2018 is extruded from the third pipe 2019 and the exhaust valve 2020. When the cutter 204 is about to rise and lift after the cutting is completed, the linkage plate 203 drives the first linkage frame 2023 to move upward. The first linkage frame 2023 pulls the upper end of the airbag 2018 upward, that is, the airbag 2018 expands to form a negative pressure, so that air flows into the airbag 2018 through the second pipe 2017, the first pipe 2016, the first round rod 2014, the groove 91, the fourth pipe 2021 and the intake valve 2022. That is, the second pipe 2017 performs an air suction operation to suck the workpiece to be cut 4 tightly on the upper side of the support plate 2015. During use, the airbag 2018 enables the second pipe 2017 to perform an air suction operation, sucking the workpiece to be cut 4 tightly on the upper side of the support plate 2015 during the process of the cutter 204 separating from the workpiece to be cut 4, strengthening the workpiece to be cut 4, further improving the stability of the die-cutting operation, and the airbag 2018 is driven by the up and down movement of the linkage plate 203, without the need to additionally set a driving part, which is beneficial to cost saving;

[0044] When the cutter 204 needs to be replaced, manually push the pull rod 2011 to move to the right. The pull rod 2011 drives the second linkage block 2010 to move to the right, so that the inclined surface of the second linkage block 2010 contacts the first linkage block 209, so that the second linkage block 2010 pushes the first linkage block 209 to move away from the linkage plate 203. The first linkage block 209 drives the fixed plate 208 to move and stretches the second elastic telescopic rod 207, so that the fixed plate 208 is separated from the cutter 204 and stops fixing the cutter 204. Then manually take out the cutter 204 and replace it. Then manually pull the pull rod 2011 to move back to the original position to the left, so that the second elastic telescopic rod 207 rebounds to drive the first linkage block 209 to insert into the new cutter 204 to fix it. During use, manually only need to push the pull rod 2011 to unlock the cutter 204, which is beneficial to shortening the replacement time of the cutter 204, making the replacement process more convenient and greatly improving the efficiency;

[0045] When replacing the cutting knife 204, since the cutting knife 204 is rectangular and needs to move upward while sleeving on the outer side of the pressing block 206, it is extremely inconvenient for manual alignment and there are certain safety hazards. At this time, start the motor 2030. The motor 2030 drives the first straight gear 2031 to rotate. The first straight gear 2031 drives the second straight gear 2032 to rotate. The second straight gear 2032 drives the first round rod 2014 to rotate. The first round rod 2014 drives the support plate 2015 to rotate, so that the support plate 2015 drives the parts on it to rotate 180 degrees, so that the receiving plate 2026 moves to the upper side of the first support frame 2. Then, manually insert the blade of the new cutting knife 204 downward into the fixing groove of the receiving plate 2026. Then, the second telescopic cylinder 2012 drives the linkage frame 2013 to move upward. The linkage frame 2013 drives the first round rod 2014 to move upward. The first round rod 2014 drives the parts on it to move upward, so that the receiving plate 2026 drives the new cutting knife 204 to move upward to the lower side of the pressing block 206. At this time, the new cutting knife 204 has been preliminarily positioned through the fixing groove on the receiving plate 2026. Then, manually push the new cutting knife 204 to move left or right. The new cutting knife 204 drives the receiving plate 2026 to move left or right. The receiving plate 2026 pushes the second connecting block 2029 to move and compresses the fourth elastic telescopic rod 2028, so as to finely adjust the left and right positions of the new cutting knife 204, so that the new cutting knife 204 is aligned with the pressing block 206 in the left and right directions. Then, manually push the new cutting knife 204 to move forward or backward. The new cutting knife 204 drives the receiving plate 2026 to move. The receiving plate 2026 drives the linkage rod 2025 to move and compresses the third elastic telescopic rod 2027, so as to finely adjust the front and back positions of the new cutting knife 204, so that the new cutting knife 204 is aligned with the pressing block 206 in the front and back directions, and further makes the new cutting knife 204 completely aligned with the pressing block 206. Then, the second telescopic cylinder 2012 drives the linkage frame 2013 to continue to move upward, inserts the new cutting knife 204 into the linkage plate 203, and completes the auxiliary replacement operation. When in use, the position of the cutting knife 204 is finely adjusted through the receiving plate 2026 to make it completely aligned with the pressing block 206, and then the cutting knife 204 is inserted into the linkage plate 203 through the receiving plate 2026 to complete the auxiliary replacement operation, avoiding the problem of difficult alignment of the rectangular cutting knife 204 during manual replacement, and covering the blade of the cutting knife 204 through the receiving plate 2026 to avoid accidental injury to workers during the replacement process, greatly improving safety.

[0049] When the edge materials generated by cutting the workpiece to be cut 4 are wound up by an external winding mechanism, the edge materials will lift the edge of the formed material in the middle of the workpiece to be cut 4, resulting in the phenomenon of the formed material falling off during the subsequent winding process. At this time, the third telescopic cylinder 301 drives the second round rod 302 to move downward, and the second round rod 302 drives the parts thereon to move downward, so that the two round rollers 305 contact the middle position of the formed material on the workpiece to be cut 4. The second round rod 302 continues to move downward, causing the adjacent expansion blocks 303 on the left and right to move away from each other, that is, the two round rollers 305 move away from each other, and roll-press the formed material on the workpiece to be cut 4, thereby avoiding the phenomenon of the formed material on the workpiece to be cut 4 warping. Moreover, the two round rollers 305 roll and press from the middle of the formed material on the workpiece to be cut 4 to both sides, making the fitting process smoother and preventing the appearance of bulges after fitting.

[0050] When the expansion blocks 303 move away from each other, they come into contact with the damping blocks 307, generating damping sliding. When the third telescopic cylinder 301 drives the second round rod 302 to move upward back to its original position, the second round rod 302 drives the parts thereon to move back to their original positions. During this process, the round roller 305 automatically moves back to its original position by gravity. Due to the certain friction between the expansion blocks 303 and the damping blocks 307, the expansion blocks 303 move slowly, so that the round roller 305 first moves upward away from the workpiece to be cut 4 and then rotates back to its original position, avoiding the round roller 305 rolling and pressing from both sides to the middle of the formed material on the workpiece to be cut 4 during the reset process, thereby preventing the phenomenon of the formed material on the workpiece to be cut 4 being folded.

[0051] The above embodiments are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
