Technical Field

Background
A shredder is a device for cutting paper, documents, etc. into small pieces, and is generally used for security treatment of documents and used paper.
The principle of paper shredders is to cut paper into small pieces by a pair of rotating cutting blades or cutterheads, so that the original document is no longer readable. Different types of shredders have different processing capacities and can process different numbers and types of sheets. The shredder can use different shearing modes such as cross cutting (cross cutting machine) or grain cutting (grain cutting machine). Cross cutting cuts the paper into small pieces, providing a relatively high level of security, while grain cutting cuts the paper into smaller grains, providing a higher level of security.
The security level of a shredder is typically rated according to the manner of cutting and granularity. The higher the security level, the finer the cut, making it more difficult to recover the original information. The security levels are generally classified from P-1 to P-7, with P-1 representing the lowest security level and P-7 representing the highest security level.
When processing a plurality of papers, especially papers of different sizes and different thicknesses, a single-gear shredder has some problems when processing different loads, and mainly focuses on the following aspects:
when the number of sheets processed exceeds the load carrying capacity of the machine, a single gear shredder may become overloaded, causing the machine to jam or break. This affects the working efficiency and increases maintenance costs.
A single gear shredder can generally only work under specific loads, and is difficult to automatically adapt to paper of different sizes, thicknesses and types.

The inner walls of the embedding groove 6745 and the shell 6741 are provided with positioning grooves 6747 which are communicated with each other, the limiting block 673 is provided with a sliding hole 6748, the sliding hole 6748 is internally and slidably connected with positioning pins 6749 matched with the positioning grooves 6747, the positioning pins 6749 are L-shaped, the other ends of the positioning pins 6749 are arranged on the front surface of the limiting block 673, and the positioning grooves 6747 are provided with return springs 68;
the connecting rod 672 is sleeved with a push-pull spring 69, the push-pull spring 69 is arranged in the embedding groove 6745, one end of the push-pull spring 69 abuts against the limiting block 673, and the other end of the push-pull spring 69 abuts against the knob 6744.
The stroke amplifying mechanism 64 comprises a fixed pulley 641 arranged at the other end of the compression bar 63, a rope 642 is wound on the fixed pulley 641, one end of the rope 642 is connected with a fixed block 643, the fixed block 643 is arranged on the limiting guide rail in a sliding manner, one side of the fixed block 643 is fixedly connected with the sliding rod 65, and the other end of the rope 642 is connected with a fixed seat 644.
When the knob switch 674 is used, a user firstly presses the limiting block 673, and the limiting block 673 is connected with the connecting rod 672, so that the gear 671 can be driven to move, the gear 671 moves to one side close to the rack 66, the gear 671 and the rack 66 are in meshed connection, after the limiting block 673 moves to the embedding groove 6745, the positioning pin 6749 is inserted into the positioning groove 6747, and it is required to say that the positioning groove 6747 on the shell 6741 is an annular groove, and after the knob 6744 is embedded into the shell 6741, the positioning pin 6749 can rotate along the positioning groove 6747 on the shell 6741; simultaneously, the limiting block 673 is pressed to move, and the knob 6744 is pressed to move towards the inner side of the shell 6741, so that the guide block 6746 connected to the knob 6744 is connected with the resistor 6743, and the pulverizer is electrified;
the pulverizer works normally after power is on, one example of which is:
when more crushed paper, for example 200 sheets of paper are crushed at one time, the thickness of the paper is 2cm, at this time, 200 sheets of paper are fed into the paper feeding assembly 5 from the paper feeding port 3, the paper pressing plate 61 moves downwards by 2cm, due to the arrangement of the travel amplifying mechanism 64, the pressing plate 61 can drive the pressing rod 63 and the fixed pulley 641 to move downwards by 2cm, at this time, the rope 642 wound on the fixed pulley 641 can pull the fixed seat 644 to move by 4cm, so as to drive the sliding rod 65 to move by 4cm, the rack 66 on one side of the sliding rod 65 is meshed with the gear 671, so as to drive the gear 671 to rotate, and due to the rotation of the gear 671, the knob 6744 can be driven to rotate, so that the knob 6746 moves along the resistor 6743, and thus the resistance of the resistor 6743 can be adjusted.
Another example is: in the shredding process, when there is less paper to be shredded, the paper pressing platen 61 is limited in the moving distance, and the movement between the rack 66 and the gear 671 is limited, for example, ten sheets of paper are shredded at a time, the paper thickness is about 1 mm, and the distance that causes the platen 61 to move down is also one mm, since the knob switch 674 is connected to the rack 66 via the gear 671, in which case the adjustment of the knob switch 674 may not significantly affect the resistance value and the rotation speed of the driving mechanism 9.
The paper size and thickness automatic adaptation device can automatically adapt to the number and thickness of paper in the grinding process, avoid unnecessary speed change when a small amount of paper is processed, and stabilize operation. Meanwhile, when the number of sheets is large, the distance by which the platen 61 moves down increases, resulting in an increase in displacement of the other portion, which causes rotation of the gear 671, thereby adjusting the resistance by the knob switch 674, thereby affecting the speed of the driving mechanism 9. This automatic adaptation can maintain proper speed and efficiency at different comminution loads.
The control switch 67 controls the operation of the driving mechanism 9 according to the rotation state of the gear 671. This may affect the rotational speed of the shredding blade 424, thereby adjusting the efficiency and speed of the shredding process.
The push-pull spring 69 can be arranged to disengage the rack 66 from the gear 671;
specifically, when the crushing is not needed, the positioning pin 6749 is manually broken to remove the positioning pin 6749 from the positioning groove 6747, and the connecting rod 672 and the limiting block 673 are reset due to the action of the push-pull spring 69, so that the rack 66 is separated from the gear 671, the crusher is not operated, and the power failure and the stop are realized.

In use, the drive motor 91 is activated, and the output of the drive motor 91 transmits power to the slide rod 932 via the drive shaft 92, causing the slide rod 932 to rotate.
Wherein the third bevel gear 933 and the fourth bevel gear 934 of the clutch mechanism 93 mesh with the first bevel gear 423 of the pulverizing mechanism 4, one of which is an acceleration gear and the other of which is a deceleration gear, and the rotational speed of the pulverizing mechanism can be controlled by acceleration or deceleration, thereby affecting the pulverizing efficiency.
When paper enters from the paper inlet 3, the pressing plate 61 moves downwards, the sliding rod 65 can move downwards through the stroke amplifying mechanism 64, so that the fixing plate 82 is driven to move downwards, the fourth conical gear 934 is meshed with the first conical gear 423, torque is increased, speed is reduced, and thicker paper is convenient to crush.
