Embodiment Construction

[0016] Such as figure 1 As shown, the punch 1 of the present invention includes a punch frame 2 with a punch base 3, and the base has a paper mold outlet opening 4. The perforator frame also includes a horizontal perforator frame part 5 and a paper thickness limiting part 6. Each of these components includes a perforation guide opening 7, 8 for installing the perforating needle 9 to move along the longitudinal axis of the perforating needle. The guide openings 7 and 8 are axially aligned with the exit opening 4 of the paper mold along the longitudinal axis of the perforating needle 9. The longitudinal movement of the perforating needle in the downward direction will cause the perforating needle to move into the paper exit opening 4.

[0017] The movement of the piercing needle is realized by the piercing needle driving part 10, and the driving part mounted with a pivot can rotate around the point 11. By applying a force F to the extension end 11 of the driving member, the pivotin...

Abstract

A perforating needle (9) with a V-shaped groove (18), the size and structure of the groove are adjusted to perforate the paper pile (s), the height of the paper pile can be changed within a certain range. According to the invention, the height of the groove is made greater than the maximum height of the punched paper stack.

Description

technical background [0001] Non-planar punching needles have been proposed and used in paper punching equipment (US Patent Specification Nos. 4,257,300; 4,449,436 and 4,763,552). Although some of these perforations operate satisfactorily, they require considerable force to perforate through a stack of paper. This in turn requires the perforated parts to be made to withstand these forces. The larger the pile of paper to be punched, the higher the punching force required. This is particularly significant for manual perforation, where the individual has to apply perforation force. Summary of the invention [0002] The present invention is an improvement of the existing perforation technology, and the force required to realize the perforation operation is relatively small. In summary, the present invention includes a perforating needle with a V-shaped groove. The size and structure of the groove are adjusted to perforate the paper pile, and the height of the paper pile can be changed...
