[0038] The present invention will now be described in detail with reference to the accompanying drawings.

[0039] like Figure 1-4 As shown, a paper punching device includes a punching frame 1. The punching frame 1 includes a pair of longitudinally spaced frame side plates 11. A plurality of parallelly spaced transverse connecting strips 12 are installed between the two frame side plates 11. The punching frame 1 is provided with a paper forward conveying mechanism 10 and a punching mechanism 2 for punching holes in the forward conveyed paper. The conveying mechanism 10 includes an active guide roller 18 that cooperates with the punching mechanism 2. A first conveying roller 13 is provided behind the active guide roller 18, and a second conveying roller 14 is provided in front of the active guide roller 18. The paper moves forward sequentially along the first conveying roller 13, the active guide roller 18, and the second conveying roller 14.

[0040] The punching mechanism 2 includes a punching guide roller 21 disposed above the active guide roller 18. The punching guide roller 21 is detachably fitted with a plurality of mold mounting sleeves 22 at equal intervals along its length. The mold mounting sleeves 22 are fitted with punching molds. The active guide roller 18 has a plurality of guide holes 19 radially formed on its surface to cooperate with the punching molds.

[0041] The punching frame 1 is equipped with a paper scrap cleaning mechanism 5, which includes a paper scrap collection box 46 arranged below the active guide roller 18. A guide flare 47 is installed on the top of the paper scrap collection box 46. The punching frame 1 is equipped with a blowing assembly 4, which includes multiple blowing areas with blowing nozzles arranged toward the paper scrap collection box 46. The blowing assembly 4 blows paper scraps from the paper into the paper scrap collection box 46 through the blowing nozzles.

[0042] The paper to be punched is conveyed forward by the conveying mechanism 10. The paper passes through the first conveying roller 13, the active guide roller 18 and the second conveying roller 14 in sequence. When passing the active guide roller 18, it cooperates with the punching mechanism 2. The punching mold fitted on the punching guide roller 21 punches holes in the paper, so that the paper forms holes. After punching, the paper scraps in the holes are blown by the air outlet arranged on the punching machine frame 1 to the paper scrap collection box 46 and collected by the paper scrap collection box 46. There is no need for manual removal of paper scraps. Since the paper scraps are light, the air blowing assembly 4 can blow the paper scraps from the paper surface to the paper scrap collection box 46, saving labor costs and facilitating subsequent paper processing.

[0043] Both the conveying mechanism 10 and the punching mechanism 2 are installed between the two frame side plates 11. The conveying mechanism 10 also includes a paper guiding structure arranged on the punching frame 1. The paper guiding structure includes a pair of spaced-apart guide bars 15, with a gap between the two guide bars 15 for paper to pass through. A guide fixing seat 16 is installed on the frame side plate 11, and a guide rotating seat 17 capable of longitudinal rotation is installed on the guide fixing seat 16. The two guide bars 15 are respectively connected to the guide rotating seat 17. The paper passes through the gap between the two guide bars 15. Since the guide rotating seat 17 can swing around the guide fixing seat 16, the direction of the paper can change after passing through the gap between the guide bars 15, and it can continue to be conveyed at different angles.

[0044] The mold then enters the active guide roller 18 and cooperates with the perforating guide roller 21. The mold mounting sleeve 22 includes two semi-circular ring sleeves 23. One semi-circular ring sleeve 23 has a recessed mounting groove 24, through which a first mounting hole 25 is formed laterally. The other semi-circular ring sleeve 23 has a second mounting hole 26 coaxially aligned with the first mounting hole 25. A locking connecting rod connects the first mounting hole 25 and the second mounting hole 26. The mold mounting sleeve 22 is installed by engaging the first mounting hole 25 and the second mounting hole 26, and then inserting the locking connecting rod. The punching die includes an annular block 27, which is coaxially sleeved on one of the semicircular ring sleeves 23 of the die mounting sleeve 22. The punching die is mounted on the semicircular ring sleeve 23. The paper is conveyed forward by the active guide roller 18 rotating. The punching guide roller 21 rotates synchronously to punch holes in the paper. The punching cutter 28 of the punching die can be embedded into the guide hole 19 of the active guide roller 18 to prevent damage to the punching cutter 28 of the punching die.

[0045] It should be noted that the active guide roller 18 and the perforating guide roller 21 rotate synchronously and at the same speed. Therefore, the punching knife 28 of the perforating mold sleeved on the perforating guide roller 21 can be embedded into the guide hole 19 of the active guide roller 18, thereby realizing uninterrupted perforation. That is, the active guide roller 18 and the perforating guide roller 21 rotate continuously in a cycle, and the paper moves forward continuously. The active guide roller 18 and the perforating guide roller 21 cooperate to continuously and uninterruptedly perforate, further increasing the perforation efficiency.

[0046] The punching mechanism 2 also includes an adjustment mechanism 3 that can adjust the distance between the punching guide roller 21 and the active guide roller 18. The adjustment mechanism 3 includes a side sliding groove 31 longitudinally opened on the side plate 11 of the frame. A bearing seat 32 is installed in the side sliding groove 31. The punching guide roller 21 is connected to the bearing seat 32. The bearing seat 32 can move longitudinally along the side sliding groove 31. In this embodiment, the height of the bearing seat 32 can be adjusted by the sliding cooperation between the bearing seat 32 and the side sliding groove 31. The height of the punching guide roller 21 installed in the bearing seat 32 can change, which can punch paper of different thicknesses. It can also install punching molds of different thicknesses to improve the versatility of installation.

[0047] Specifically, a transverse mounting plate 33 is installed on the top of the side sliding groove 31. The transverse mounting plate 33 is equipped with a longitudinally arranged adjusting screw 36 and a transmission sleeve 35 that cooperates with the adjusting screw 36. The transverse mounting plate 33 has a movable hole 34 for the adjusting screw 36 to pass through. The transmission sleeve 35 is fixedly installed in the movable hole 34. The bottom of the adjusting screw 36 is connected to the bearing seat 32. By rotating the adjusting screw 36, the adjusting screw 36 and the transmission sleeve 35 are in transmission cooperation, and the adjusting screw 36 can move up and down. The bearing seat 32 connected to the adjusting screw 36 can thus move up and down to adjust the installation height of the perforated guide roller 21.

[0048] Furthermore, the blower assembly 4 also includes a blower mounting base 41 installed on one of the top-positioned transverse connecting bars 12. Multiple blower mounting bases 41 are included. The transverse connecting bars 12 are arranged with guide rails 42 along their length. Each blower mounting base 41 is provided with a mounting slider 43 that slides along the guide rails 42. A blower seat 44 is mounted on the blower mounting base 41, and the air outlet is a blower nozzle 45 disposed on the blower seat 44. The blower nozzle 45 can swing longitudinally around the blower seat 44 to adjust the blowing angle. In this embodiment, the blower mounting base 41 can adjust its transverse position by sliding the mounting slider 43 against the guide rails 42, thereby blowing away paper scraps from different locations on the paper. Furthermore, by swinging the blower nozzle 45, the airflow direction can be changed, and both the transverse and longitudinal angles can be adjusted, resulting in a wider blowing range.

[0049] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0050] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
