An efficiency-enhancing component to improve the cutting effect of the cutting component is fixedly installed on one side of the cutting assembly. The efficiency-enhancing component includes a first gate-shaped plate 5, one side of which is fixedly installed on one side of the gate-shaped support plate 20.The first portal-shaped plate 5 is slidably connected to the portal-shaped long plate 10. A threaded shaft 4 is threadedly connected inside the first portal-shaped plate 5. A connecting shaft 27 is fixedly connected to the top of the threaded shaft 4. A holding post 1 is fixedly connected to the top of the connecting shaft 27. A limit ring 28 is fixedly connected to the outer surface of the connecting shaft 27. A tapered post 26 is fixedly connected to the bottom of the threaded shaft 4. A connecting long plate 7 is rotatably connected to the outer surface of the tapered post 26 and the bottom of the threaded shaft 4. The connecting long plate 7 is slidably installed inside the first portal-shaped plate 5. A holding post 1 is fixedly connected to the bottom of the connecting long plate 7. Two rubber pressure plates 8 are movably installed inside the first portal plate 5. A first positioning component is fixedly installed on one side of the efficiency-enhancing component. The first positioning component includes a positioning square plate 24 and a second positioning vertical plate 6. One side of the positioning square plate 24 is fixedly installed on one side of the connecting long plate 7, and one side of the second positioning vertical plate 6 is fixedly installed on one side of the first portal plate 5. The positioning square plate 24 is slidably installed inside the first portal plate 5, and the second positioning vertical plate 6 is slidably connected to the connecting long plate 7. The top of the efficiency-enhancing component is fixedly installed with a limiting component, which includes a first positioning plate 3. The bottom of the first positioning plate 3 is fixedly installed on the top of the connecting long plate 7. The first positioning plate 3 is slidably installed inside the body of the first portal plate 5. The top of the first positioning plate 3 is fixedly connected to a supporting horizontal plate 2. The supporting horizontal plate 2 is slidably connected to the portal support plate 20. The supporting horizontal plate 2 is rotatably connected to the connecting shaft 27, the limiting ring 28, and the holding column 1, respectively. This is achieved through the supporting base plate 9, the cutting component, the efficiency-enhancing component, the first positioning component, and... The limiting component enables the cutting component to cut the flexible label, the efficiency-enhancing component to improve the cutting effect of the cutting component, the first positioning component to position the efficiency-enhancing component, and the limiting component to limit the efficiency-enhancing component. This allows the device to cut the flexible label. When cutting the flexible label, the device can press firmly on both sides of the cut area, preventing the cutting effect from being reduced due to offset of the cut area, thus improving the overall cutting efficiency.

[0019] In use, the initial state of this device is as follows: the limiting screw 13 is threadedly connected to the threaded groove 15; the connecting plate 7 and the rubber pressure plate 8 are both located inside the first gate-shaped plate 5; the cutting blade 23 is located above the gate-shaped rod 11, and the top of the connecting horizontal plate 17 is on the same plane as the top of the supporting horizontal plate 2. When it is necessary to use this device to cut flexible labels, move the flexible label and place it flat inside the gate-shaped plate 10, so that the cutting point of the flexible label corresponds to the cutting blade 23. Rotate the holding column 1 so that the holding column 1 rotates along the supporting horizontal plate 2, so that the connecting shaft 27 and the limiting ring 28 rotate along the supporting horizontal plate 2. The internal rotation of the horizontal plate 2 causes the bottom end of the threaded shaft 4 to rotate along the connecting long plate 7, causing the conical column 26 to rotate along the internal rotation of the connecting long plate 7. Under the action of the threaded transmission, the threaded shaft 4 rotates and moves downward along the internal rotation of the first portal plate 5, causing the connecting long plate 7 to slide along the internal rotation of the first portal plate 5 and the second positioning plate 6 respectively, causing the rubber pressure plate 8 to slide along the internal rotation of the first portal plate 5, causing the positioning square plate 24 to slide downward along the internal rotation of the first portal plate 5, causing the first positioning plate 3 to slide downward along the internal rotation of the first portal plate 5, and causing the supporting horizontal plate 2 to slide downward along the portal support plate 20.

[0020] When the threaded shaft 4 rotates along the inside of the first portal plate 5 and moves downward to the maximum distance, the rubber pressure plate 8 slides out from the inside of the first portal plate 5 and is located inside the portal long plate 10. With two rubber pressure plates 8, the two rubber pressure plates 8 can contact the two sides of the flexible label cutting area and deform. Move the connecting line, connect one end of the connecting line to the power supply, and connect the other end of the connecting line to the connecting terminal 21. Start the electric telescopic rod 19, extend the electric telescopic rod 19 downward, and move the connecting horizontal plate 17 and the cutting blade 23 downward. The limiting long rod 18 slides downward along the inside of the portal support plate 20. Under the action of the cutting blade 23, the cutting blade 23 can cut the flexible label cutting area. At this time, this device can be used to cut the flexible label.

[0021] When using this device to cut flexible labels, the two rubber pressure plates 8 contact the two sides of the cutting area of ​​the flexible label and deform under the action of deformation, so that the two sides of the cutting area of ​​the flexible label can be pressed tightly, so that the cutting area of ​​the flexible label can be prevented from shifting, thus improving the cutting effect.

[0022] In summary, this device can cut flexible labels. When using this device to cut flexible labels, it can press the two sides of the cut area of ​​the flexible label firmly, so as to avoid the cutting effect being reduced due to the offset of the cut area of ​​the flexible label, thus improving the cutting effect.

An adjustment component for convenient adjustment of the cutting position of the cutting component is fixedly installed on one side of the cutting component. The adjustment component includes the support plate 12, one side of which is fixedly installed on one side of the gate-shaped plate 10. The support plate 12 is fixedly connected to a support base plate 9. A trapezoidal plate 16 and a gate-shaped bar 11 are fixedly connected to the top of the support plate 12. The trapezoidal plate 16 is fixedly installed... Inside the portal-shaped rod 11, the supporting long plate 12, trapezoidal long plate 16, and portal-shaped rod 11 are all slidably connected to the portal-shaped support plate 20. Multiple threaded grooves 15 are respectively opened on one side of the supporting long plate 12. A second positioning component of the positioning and adjustment assembly is fixedly installed on both one and the other side of the cutting assembly. The second positioning component includes a first positioning crossbar 22 and a second positioning crossbar 25. One side of the first positioning crossbar 22 is fixedly installed on one side of the portal-shaped support plate 20, and one side of the second positioning crossbar 25 is fixedly installed on the other side of the portal-shaped support plate 20. On one side, the first positioning crossbar 22 is slidably installed inside the body of the portal-shaped long plate 10, and the second positioning crossbar 25 is slidably installed inside the body of the portal-shaped rod 11.

The fixing component includes a second portal-shaped plate 14, one side of which is fixedly installed on one side of the portal-shaped support plate 20. The second portal-shaped plate 14 is slidably connected to the portal-shaped rod 11 and the supporting long plate 12 respectively. A limiting screw 13 is threadedly connected inside the body of the second portal-shaped plate 14. The limiting screw 13 and the threaded groove 15 The threaded connection, through the setting of the adjustment component, the second positioning component, and the fixing component, allows the adjustment component to easily adjust the cutting position of the cutting component, the second positioning component to position the adjustment component, and the fixing component to fix the adjustment component. Before using this device to cut flexible labels, when the cutting position of this device needs to be adjusted, the cutting position of this device can be changed, so as to avoid increasing the difficulty of adjusting the cutting position due to the difficulty of adjusting the cutting position, and to make the cutting position of this device easy to adjust.

[0024] In use, before cutting the flexible label with this device, when the cutting position needs to be adjusted, rotate the limiting screw 13 to disengage it from the threaded groove 15 and position one end of the limiting screw 13 inside the second portal plate 14. Move the portal support plate 20 so that it slides along the portal long plate 10, the support long plate 12, the trapezoidal long plate 16, and the portal rod 11, respectively, so that the first portal plate 5 slides along the portal long plate 10, and the first positioning crossbar... 22 slides along the inside of the gate-shaped long plate 10, causing the second positioning crossbar 25 to slide along the inside of the gate-shaped rod 11, causing the second gate-shaped plate 14 to slide along the gate-shaped rod 11 and the supporting long plate 12 respectively, so that the cutting position of this device can be changed. When the cutting position of this device is the required cutting position, and when the limiting screw 13 corresponds to the threaded groove 15, the limiting screw 13 is rotated in the opposite direction, so that the limiting screw 13 is threadedly connected to the threaded groove 15. At this time, the cutting position of this device can be adjusted.

[0025] When adjusting the cutting position, the device can easily adjust the cutting position by sliding the portal-shaped support plate 20 along the portal-shaped long plate 10, the support long plate 12, the trapezoidal long plate 16, and the portal-shaped rod 11, and by sliding the first portal-shaped plate 5 along the portal-shaped long plate 10, the first positioning crossbar 22 along the inside of the portal-shaped long plate 10, the second positioning crossbar 25 along the inside of the portal-shaped rod 11, and the second portal-shaped plate 14 along the portal-shaped rod 11 and the support long plate 12.

[0026] In summary, by incorporating the adjustment component, the second positioning component, and the fixing component, the cutting position of this device can be changed before the flexible label is cut, thus avoiding the increased difficulty in adjusting the cutting position and enabling convenient adjustment of the cutting position.
