[0001] The invention relates to the technical field of paper shredders, in particular to a financial paper shredder. Background Art

[0002] Finance refers to the economic activities and management related to the movement of funds in the production and operation process of an enterprise. It involves the raising, use, management and allocation of funds, including capital raising, cost control, income realization, profit distribution and other aspects. The main goal of financial management is to optimize the efficiency of fund use, ensure the security and liquidity of enterprise funds, and improve the profitability and market competitiveness of enterprises. Financial activities include not only accounting and financial reporting, but also financial analysis, budget management, risk control and other aspects, and are an important part of enterprise management. Good financial management can provide a solid financial foundation and decision-making support for the development of enterprises.

[0003] In order to prevent the leakage of personal information, financial data and business secrets in the financial, accounting and tax industries, professional shredders are needed to shred paper materials. At present, the existing shredders cannot guide the paper materials to be shredded due to the lack of effective guide structures, nor can they adapt the conveying spacing between the two sets of guide rollers according to the thickness of the paper materials. At the same time, they cannot assist in discharging the shredded paper scraps. As a result, the existing shredders may encounter problems such as jamming and blockage caused by the unsmooth feeding and discharging of paper materials during use, which ultimately affects the normal operation and efficiency of the shredders.

[0004] Based on this, we propose a financial shredder to solve the above-mentioned problems. Summary of the invention

[0031] Working principle: The present invention uses a paper guide box 3 installed on the top of the support frame 1. The paper guide box 3 is mainly composed of parts such as a paper guide groove 10, a guide roller 11, a transmission shaft 12, and an adjustment base block 13. When the drive box 28 in the drive assembly 5 is powered on, the transmission belt can be used to drive the transmission devices 6 installed on both sides to rotate. Because the transmission device 6 is connected to the two groups of crushing shafts 9 that are rotatably connected inside the crushing groove 8, the two groups of crushing shafts 9 can be driven to rotate inside the crushing groove 8. The rotating transmission device 6 can also drive one of the guide rollers 11 inside the paper guide groove 10 to rotate through the transmission toothed belt. Because the two groups of guide rollers 11 are in rolling contact, when the paper material to be crushed is inserted into the paper guide groove 10, the two groups of rolling contact guide rollers 11 are in rolling contact. The guide rollers 11 can guide and convey the inserted paper materials downward. Since the two groups of crushing shafts 9 are located directly below the two groups of guide rollers 11, the two groups of rotating crushing shafts 9 can crush the paper materials guided and conveyed downward, and cooperate with the adjustment base blocks 13 that are respectively rotatably connected at both ends of one group of guide rollers 11. The adjustment base block 13 is designed to slide with the guide bar 14 through the first guide groove 18, and the first compression spring 15 is installed at one end, so that the device can adaptively adjust the spacing between the two groups of guide rollers 11 according to the thickness of the paper material used. It can be seen from the above that the shredder designed by the present invention can guide and convey the paper materials to be crushed, and can also prevent the feeding jam caused by too much paper material.

The V-shaped plate 23 can be limitedly connected between the two groups of retaining grooves 20 through a structural design of sliding cooperation between the guide plate 26 and the second guide groove 21. When the drive box 28 in the drive assembly 5 is powered on, the rotating cam 34 connected to one side of the fixed plate body 33 can be driven to rotate through the transmission toothed belt. Because the rotating cam 34 matches the structure of the support plate holder 24, and the rotating cam The wheel 34 is in rolling contact with the support plate 24, and the rotating cam 34 can push upward the V-shaped plate 23 that is limitedly connected between the two groups of retaining grooves 20. The V-shaped plate 23 can slide up and down between the two groups of retaining grooves 20 under the pushing action, and can also be reset by the second compression springs 27 respectively installed at both ends of the guide plate 26. This is repeated, so that the V-shaped plate 23 can shake and discharge the falling shredded paper scraps, which can prevent the shredded paper scraps from piling up when they fall freely under their own gravity, and avoid the problem of clogging of the shredded paper scraps in the process of discharging downward.
