The dust collection mechanism comprises a first collection box 11 fixedly connected to the inner side of the upper end of the support frame 1, a filter plate 13 fixedly connected to the inner bottom wall of the first collection box 11, a vacuum cleaner 12 fixedly mounted on the lower side of the first collection box 11, a guide pipe 14 connected to the left side of the first collection box 11, and a second collection box 15 threadedly connected to the lower side of the guide pipe 14.

[0026] Among them, the punching mechanism includes an electric cylinder 2 fixedly installed on the inner top wall of the support frame 1, an upper punching mold 3 fixedly connected to the output end of the electric cylinder 2, a tool 4 fixedly connected to the lower side of the upper punching mold 3 and a limit assembly slidably sleeved on the left and right sides of the upper punching mold 3. The limit assembly includes a limit rod 5 slidably sleeved on the left and right inner walls of the upper punching mold 3, and the outer wall of the lower side of the limit rod 5 is slidably sleeved on the left and right sides of the lower punching mold 6. The filter plate 13 has an italic structure, and a through hole 16 is opened in the middle of the upper surface of the lower punching mold 6. The upper side of the first collecting box 11 passes through the support frame 1 and extends to the outside. A driving structure is provided on one side of the grinding roller 10, and the driving structure is a driving motor.

[0027] Example 2:

[0028] See also Figure 1 and Figure 3 On the basis of embodiment 1, it includes a limiting mechanism for limiting the position of the automobile interior fixedly connected to the upper side of the lower punching mold 6, the limiting mechanism includes a horizontal limiting plate 8 fixedly connected to one end of the upper side of the lower punching mold 6, two fixed plates 17 fixedly connected to the front end face of the lower punching mold 6, two right-angle side limiting plates 7 slidably connected to the upper side of the lower punching mold 6, and a limiting pin 18 inserted on one side of the right-angle side limiting plate 7. A plurality of positioning holes 19 are provided on the surface of the fixed plate 17, and the plurality of positioning holes 19 are arranged at equal distances vertically. Two slide grooves 20 are provided on the upper surface of the lower punching mold 6, and the lower side of the right-angle side limiting plate 7 is slidably connected in the slide groove 20.

[0029] By adopting the above technical solution, one side of the automobile interior is attached to the surface of the horizontal limit plate 8, and the two ends of the other side can respectively contact the opposite sides of the two right-angle side limit plates 7, and the lower side of the right-angle side limit plate 7 is used to slide in the slide groove 20 according to the different changes in the length and width of the interior, and the limit pin 18 is used to be inserted into the corresponding positioning hole 19, so as to achieve the limitation of the interior around and avoid the offset during punching.

[0030] The working principle of the above embodiment is:

[0031] One end of the car interior is placed on one side surface of the horizontal limit plate 8, and the two corners of the other side surface are respectively against the surface of the right-angle side limit plate 7. According to the size of the interior, it slides to the corresponding position in the slide groove 20, and takes out the limit pin 18 and inserts it into the corresponding positioning hole 19 to fix the right-angle side limit plate 7. The electric cylinder 2 is started to drive the upper punching die 3 and the lower side tool 4 to punch the interior. After a long time of punching, the surface of the tool 4 will be worn. At this time, the tool 4 is moved to the inside of the first collection box 11 in the through hole 16. The output end of the electric push rod 21 drives the grinding roller 10 to move toward the surface of one side of the tool 4, and the telescopic rod 9 extends synchronously to support the grinding roller 10, and then the driving member connected to one side of the grinding roller 10 is started to grind the surface of the tool 4 to make it sharper. At the same time, the vacuum cleaner 12 is turned on to generate suction to adsorb the dust generated by grinding on the surface of the filter plate 13. After grinding is completed, the tool 4 returns to its original position under the action of the electric cylinder 2. When the vacuum cleaner 12 is turned off, the dust will naturally move to the left and be discharged from the guide pipe 14 to the second collection box 15 for collection.
