Figure 1 The device includes waste material 11, auxiliary rod 13 and mesh 12. The auxiliary rod 13 is connected to the mesh 12. Both ends of the mesh 12 are connected to the extended part of the waste material 11. There is a gap between the upper and lower ends of the mesh 12 and the waste material 11. The device can be used to disconnect the extended part of the waste material 11 from the mesh 12.

[0027] A punching device for an electronic cigarette heating wire strip comprises an upper mold 2, a lower mold 3 and a base 4. The upper mold 2 is provided with a lifting assembly 5, which is used to drive the upper mold 2 to rise and fall in the vertical direction. The upper mold 2 is provided with a positioning pin 6, a side pressure block 7 and a middle pressure block 8. The positioning pin 6, the side pressure block 7 and the middle pressure block 8 are used to position the heating wire strip 1; the upper mold 2 is provided with an upper punch 9, which is used to punch and cut the heating wire strip 1 so that the extension part of the waste material 11 is disconnected from the mesh 12; the lower mold 3 is installed on the base 4, and the lower mold 3 is provided with a supporting lower plate 10, which is used to place the heating wire strip 1. A rectangular protrusion 14 is provided on the lower mold 3. The supporting lower plate 10 is provided with a rectangular cylinder 15, which is sleeved on the rectangular protrusion 14. The height of the rectangular cylinder 15 is greater than the height of the rectangular protrusion 14, so that the cylinder wall of the rectangular cylinder 15 and the upper surface wall of the protrusion form a rectangular groove. The heating wire strip 1 is placed on the upper surface of the supporting lower plate 10, and the mesh 12 is located above the rectangular groove. The waste material 11 is in contact with the supporting lower plate 10.

[0028] Specifically, when punching the heating wire strip 1, in the first step, the operator first puts the rectangular tube 15 on the rectangular protrusion 14, and then places the heating wire strip 1 on the supporting lower plate 10. It is worth noting that the operator needs to place the mesh 12 of the heating wire strip 1 on the rectangular groove; in the second step, the operator uses the lifting component 5 to drive the upper mold to press down, driving the positioning needle 6, the middle pressure block 8, the side pressure block 7 and the upper punch 9 to press down. It is worth noting that a needle is opened on one side of the waste material 11. Hole 16, the supporting lower plate 10 is provided with a positioning hole 17, and the positioning needle 6 passes through the pin hole 16 and the positioning hole 17 in sequence, so that the positioning needle 6 can position the heating wire strip 1, so that the upper punch 9 can press down to cut off the extended part of the waste material 11 and the mesh 12; compared with directly punching the heating wire strip 1, using the positioning needle 6 to fix the heating wire strip 1 on the supporting lower plate 10 and then punching it out, improves the accuracy of the upper punch 9 on the heating wire strip 1, thereby improving the yield of the heating wire mesh 12.

[0029] In this embodiment, a groove 18 is provided on the upper mold 2, and the opening direction of the groove 18 is oriented in the horizontal direction so that the operator can better observe the inside of the groove 18. The upper mold 2 is also provided with a plurality of slide grooves 19 connected to the groove 18. The plurality of slide grooves 19 are all in a vertical direction. The side pressure block 7 and the middle pressure block 8 are partially located in the slide groove 19, and the side pressure block 7 and the middle pressure block 8 are both slidably connected to the groove wall of the slide groove 19. The upper end of the side pressure block 7 is fixedly provided with a spring 20, which is located in the groove 18, and the upper end of the spring 20 is fixed to the upper groove wall of the groove 18. Connection; A spring 21 is fixedly provided on the upper end of the middle pressure block 8, and the spring 21 is located in the groove 18, and the upper end of the spring 21 is fixedly connected to the upper groove wall of the groove 18; specifically, there are two side pressure blocks 7, and there are two upper punches 9. The side pressure blocks 7 are located on both sides of the middle pressure block 8, and the upper punches 9 are located on both sides of the middle pressure block 8. In this embodiment, the side pressure blocks 7, the upper punches 9, the middle pressure block 8, the upper punches 9, and the side pressure blocks 7 are arranged in sequence, and the end face of the middle pressure block 8 and the side connection of the middle pressure block 8 are arc surfaces, and the lower end of the upper punch 9 is an inverted prism shape.

[0030] When the upper die 2 is in operation, the upper die 2 moves downward, driving the side pressing blocks 7, the upper punch 9 and the middle pressing block 8 to move downward, so that the side pressing blocks 7 and the middle pressing block 8 press the heating wire strip 1, and then the upper cutting head punches the extended part of the waste material 11 and the mesh 12. It is worth noting that in this embodiment, the heights of the side pressing blocks 7, the upper punch 9 and the middle pressing block 8 are consistent, so that when the side pressing blocks 7 and the middle pressing block 8 press the heating wire strip 1, the upper punch 9 also just contacts the heating wire strip 1. At this time, the upper punch 9 continues to press downward, and the side walls of the side pressing blocks 7 and the middle pressing block 8 are slidably connected to the groove walls of the slide groove 19, and the downward movement distance of the side pressing blocks 7 and the middle pressing block 8 begins to be less than the upper punch 9, because at this time the spring 1 20 and the spring 2 21 are contracted, and the contracted spring 1 20 and the spring 2 21 can make the end faces of the side pressing blocks 7 and the middle pressing block 8 further press the heating wire strip 1.

[0031] In this embodiment, the lifting assembly 5 includes a cylinder 51, a U-shaped frame 52, a lever 53 and a lever connecting plate 54. The bottom end of the cylinder 51 is installed on the base 4, the piston shaft of the cylinder 51 is fixedly connected to the U-shaped frame 52, the lever 53 is rotatably connected to the U-shaped frame 52, the other end of the lever 53 is rotatably connected to the lever connecting plate 54, the bottom end of the lever connecting plate 54 is fixedly connected to the upper end of the upper mold 2, the lever 53 is rotatably connected to the intermediate connecting rod 55, and the intermediate connecting rod 55 is fixedly connected to the base 4.

[0032] When in use, the piston shaft of cylinder 1 51 extends, driving the end of the lever 53 connected to the piston shaft of cylinder 1 51 to move upward. Since the connection position height of the lever 53 and the intermediate connecting rod 55 remains unchanged, the other end of the lever 53 moves downward, driving the lever connecting plate 54 to move downward, driving the upper mold 2 to move downward.

[0033] In this embodiment, two support plates 22 are provided on the base 4, the upper ends of the support plates 22 are fixedly connected to the lower surface of the lower mold 3, and a cylinder 23 is provided on one side of the support plate 22. The piston shaft of the cylinder 23 is fixedly connected to a cylinder pressure plate 24, and the cylinder pressure plate 24 is used to press the support lower plate 10; a positioning pin is provided on the lower mold 3, and the support lower plate 10 is provided with a through hole, which is engaged with the positioning pin, so that the operator can better place the support lower plate 10 on the lower mold 3 and press the support lower plate 10 and the lower mold 3.
