[0001] The utility model relates to the technical field of punching devices, in particular to a tax document file cover punching device. Background Art
[0002] Tax information refers to various materials used to reflect taxpayers and tax collection situations, such as tax registration certificates, tax returns, tax appraisal forms, tax invoices, fine notices, as well as documents, regulations, account books, and tax registration forms. These materials are commonly referred to as tax information. Once compiled into files, these files are wrapped in kraft paper and bound with holes for easy archiving.
[0003] Since tax information is complex and involves many documents, the file itself is relatively thick. Electric punching is generally used. The electric cylinder pushes the punch knife down to open three circular holes on the file. In actual use, there are some functional deficiencies and there is room for improvement. For example, the cutter head used for opening holes generally adopts a hollow cutter head, which can prevent the file from cracking under pressure. However, the cut paper scraps are easily accumulated in the cutter head and need to be cleaned manually to avoid the cutter head being blocked, which is more troublesome. It does not have the function of automatically pushing paper to prevent accumulation. Utility Model Content

The tubular knife holder 5 is mounted on the bottom end of the electric cylinder 4. A punching head 6 is fixedly connected to the bottom end of the tubular knife holder 5. A paper pushing head 7 is arranged inside the tubular knife holder 5. A first spring 8 is welded to the top of the paper pushing head 7. A side notch 9 is provided on the right side of the tubular knife holder 5.
[0027] The inner diameter and outer diameter of the tubular knife holder 5 and the punching cutter head 6 are the same, the interiors of the tubular knife holder 5 and the punching cutter head 6 are connected, the outer diameter of the paper pushing head 7 is the same as the inner diameter of the tubular knife holder 5, the paper pushing head 7 can slide up and down along the inside of the tubular knife holder 5 and the punching cutter head 6, the top of the first spring 8 is connected to the top of the inside of the tubular knife holder 5, and the side notch 9 runs through the inner and outer ends of the tubular knife holder 5, which can discharge paper scraps in time to prevent accumulation in the cutter head;
[0028] Specifically, if Figure 1 、 Figure 2 and Figure 3 As shown, the electric cylinder 4 pushes the tubular knife holder 5 downward, and the punching head 6 at the bottom of the tubular knife holder 5 makes a round hole on the file to facilitate later binding. The paper scraps generated after the file cover is punched are accumulated in the tubular knife holder 5, and the paper pushing head 7 is squeezed and moved upward. As the electric cylinder 4 moves upward, the paper pushing head 7 is pushed by the first spring 8 to continuously push out the paper scraps inside the tubular knife holder 5 to avoid internal blockage. The side notch 9 on the side of the tubular knife holder 5 can be manually intervened when the first spring 8 cannot push.
[0029] Example 2: A fixed plate sleeve 10 is fixedly connected to both sides of the top of the front housing 3. An adjusting pressure plate 11 is inserted from bottom to top at the bottom end of the fixed plate sleeve 10. Multiple sets of second springs 12 are installed at the top end of the interior of the fixed plate sleeve 10. A file pressure plate 13 is welded to the bottom end of the adjusting pressure plate 11. A lifting ring 14 is welded to the top end of the file pressure plate 13. The bottom end of the second spring 12 is connected to the top end of the adjusting pressure plate 11. The adjusting pressure plate 11 can slide up and down along the interior of the fixed plate sleeve 10 to press the paper roll and prevent it from warping and displacement during the punching process.
[0030] Specifically, if Figure 1 、 Figure 2 and Figure 4As shown, buckle the lifting ring 14 to lift the file pressing plate 13, and the adjusting plate 11 will move up along the inside of the fixed plate sleeve 10, and the file will be placed under the file pressing plate 13. Release the lifting ring 14, and the second spring 12 will extend downward, pushing the adjusting plate 11 to move downward. The file pressing plate 13 will also press the file as a whole, reducing the probability of warping on both sides of the file during punching.
[0031] Example 3: Two groups of externally threaded limiting rods 17 are fixedly connected to the front ends of both sides of the top of the supporting base 1, and L-shaped clamping plates 15 are horizontally placed on both sides of the top of the supporting base 1. Two groups of limiting grooves 16 are provided inside the bottom end of the L-shaped clamping plate 15. The outer portion of the externally threaded limiting rod 17 is sleeved with an internally threaded positioning sleeve 18. The inner size of the limiting groove 16 matches the outer size of the externally threaded limiting rod 17. The L-shaped clamping plate 15 can slide left and right along the externally threaded limiting rod 17. The bottom end of the internally threaded positioning sleeve 18 contacts the top end of the L-shaped clamping plate 15, thereby positioning the two sides of the file and fixing its position.
[0032] Specifically, if Figure 1 、 Figure 2 and Figure 5 As shown, the L-shaped clamping plate 15 is moved to fit on both sides of the file. The limiting groove 16 and the external thread limiting rod 17 can limit the moving path of the L-shaped clamping plate 15. As the two groups of L-shaped clamping plates 15 are fitted on both sides of the file, the internal thread positioning sleeve 18 is tightened, and the internal thread positioning sleeve 18 is spirally moved down along the external thread limiting rod 17 to press the L-shaped clamping plate 15 to fix its position, and the position of the file is also fixed synchronously.
[0033] Working principle: When the present invention is in use, first, the tax information is compiled into volumes, and the volumes are compiled into files. The outside of the files are covered with kraft paper rolls, and the files and rolls are placed together on the supporting base 1. After the position is fixed, the electric cylinder 4 pushes the tubular knife holder 5 to press down, and the punching head 6 at the bottom of the tubular knife holder 5 opens a round hole on the file to facilitate later binding. The paper scraps generated after the file roll is opened are accumulated in the tubular knife holder 5, and the paper pushing head 7 is squeezed and moved upward. As the electric cylinder 4 moves upward, the paper pushing head 7 is pushed by the first spring 8 to continuously push out the paper scraps inside the tubular knife holder 5 to avoid internal blockage. The side notches 9 on the side of the tubular knife holder 5 can be manually intervened when the first spring 8 cannot push. According to the actual thickness of the file, the lifting ring 14 is buckled to lift the file pressing plate 13, and the adjusting plate 11 moves upward along the interior of the fixed plate sleeve 10. The file is placed under the file pressing plate 13. The lifting ring 14 is released, and the second spring 12 extends downward, pushing the adjusting plate 11 downward. The file pressing plate 13 thus compresses the entire file, reducing the possibility of warping on both sides of the file during punching. When placing the file, according to the actual width of the file, the L-shaped clamping plate 15 is moved to fit on both sides of the file. The limiting groove 16 and the externally threaded limiting rod 17 can limit the movement path of the L-shaped clamping plate 15. As the two sets of L-shaped clamping plates 15 fit on both sides of the file, the internally threaded locating sleeve 18 is tightened. The internally threaded locating sleeve 18 spirals downward along the externally threaded limiting rod 17, pressing the L-shaped clamping plate 15 tightly and fixing it in place, thereby simultaneously fixing the position of the file.
