Problems solved by technology

Even if the transmission ratio between the shredder wheel set and the rubber wheel set is increased, due to the narrowness of the paper path between the rubber wheel set and the shredder wheel set, when the speed of the rubber wheel set conveying paper is too fast, the paper path will If there is no space to store paper, it will cause the paper to wrinkle in the paper path, and the blocked paper will wrinkle and accumulate, causing the paper path to be blocked, causing the shredder to not work properly
The defect of low shredding efficiency of automatic shredders hinders the promotion and use of automatic shredders. How to improve the shredding efficiency of automatic shredders has become a pain point for manufacturers

Embodiment 1

[0022] Example 1: from figure 2 It can be clearly seen that the basic structure of the high-efficiency automatic shredder is the same as that of the existing automatic shredder. It includes: a casing 2 provided with a first paper inlet 1, a main frame 4 arranged in the casing 2, a shredder wheel set 5 installed on the main frame 4, a motor 6 driving the shredder wheel set 5 and The first sensor 3 is arranged in the first paper inlet 1 . The side of the first paper entrance 1 is provided with a second paper entrance 7 parallel to it, and the outside of the second paper entrance 7 is provided with an oblique paper guide plate 8 for paper placement; the second paper entrance 7 is connected with shredded paper An automatic paper feeding mechanism is provided between the cutter wheel groups 5 to guide paper into the shredding cutter wheel group 5; The operating second sensor 12 constitutes. The difference is that:

[0023] The transmission ratio between the shredder wheel set ...

Embodiment 2

[0027] Embodiment 2: The structure of the high-efficiency automatic shredder of this embodiment is the same as that of the present embodiment 1, the difference is:

[0028] The transmission ratio between the shredder wheel set 5 and the rubber wheel set 9 is 1:2.0.

[0029] The paper shredding efficiency of the high-efficiency automatic paper shredder in this embodiment is at least 50% higher than that of the existing automatic paper shredder.

Embodiment 3

[0030] Embodiment 3: The structure of the high-efficiency automatic shredder of this embodiment is the same as that of the present embodiment 1, the difference is:

[0031] The transmission ratio of the shredder wheel set 5 and the rubber wheel set 9 is 1:3.0,

[0032] The paper shredding efficiency of the high-efficiency automatic paper shredder in this embodiment is at least 100% higher than that of the existing automatic paper shredder.

Abstract

The invention provides a high-efficiency paper shredder. The high-efficiency paper shredder comprises a machine shell, a main machine frame, a paper shredding knife wheel set and a motor, wherein themachine shell is provided with a first paper inlet, the main machine frame is arranged in the machine shell, the paper shredding knife wheel set is arranged on the main machine frame, the motor is used for driving the paper shredding knife wheel set, a second paper inlet which is parallel to the first paper inlet is arranged beside the first paper inlet, an inclined guide paper board for placing paper is arranged on the outer side of the second paper inlet; and a paper conveying mechanism and a paper channel formed by a rubber wheel set and a elastic movable plate are arranged between the thesecond paper inlet and the paper shredding knife wheel set; the paper shredder is characterized in that the transmission ratio of the paper shredding knife wheel set and the rubber wheel set is improved, the conveying speed of the rubber wheel set on the paper is accelerated, the paper channel is an open type paper channel, the open type paper channel provides a paper storage space when the paperis naturally bounced off after being separated from the rubber wheel set, the larger the transmission ratio of the rubber wheel set and the paper shredding knife wheel set is, the faster the paper feeding speed of the rubber wheel set is, at a reasonable transmission ratio, the paper shredding knife wheel set can completely and smoothly cut and crush the multiple pieces of paper which are orderlyconveyed by the rubber wheel set, and the paper shredding efficiency is at least 30% higher than that of an existing automatic paper shredder, so that the working efficiency of the automatic paper shredder is greatly improved.

Description

[0001] Technical field: [0002] The invention relates to a paper shredder, in particular to a high-efficiency automatic paper shredder. [0003] Background technique: [0004] With the development of office automation, automatic paper feeding shredders came into being. Existing shredders with automatic shredding function such as figure 1 As shown, there are manual paper feeding and automatic paper feeding channels. Based on the cutting ability of the shredding knife wheel group, it can usually receive multiple pages of paper and insert and shred them at the same time. When using manual operation, the operator will insert and cut multiple pages of paper at the same time. , the shredding speed is faster. When using automatic operation, put a stack of paper to be shredded on the inclined paper guide plate. After the machine is started, the automatic paper feeding mechanism will send the paper one by one to the shredder wheel group for cutting and shredding. The shredding effici...
