Creation Description (1) [Technical Field to which the New Type belongs] This creation is a delayed stop device for a shredder drive, in particular, it refers to the use of an open-end diaphragm of an airbag to block the air intake during the compression and recovery process of the airbag, so that The airbag recovery time is prolonged, thereby delaying the closing time of the micro switch (0ff), and the shreds of paper scraped between the knife rods by the shredder drive motor can continue to operate to achieve the purpose of chip removal. [Prior art] US Patent No. 6,308,104 discloses a drive-hanging device of a paper shredder. A delay delay is set in the shredder. After the device crushes the paper by the knife rod, the motor continues to run for a short period of time. The shreds of paper scraped between the knife rods can be idled by the knife rod to achieve the purpose of chip removal; it is mainly connected to the knife rod with a belt-driven driving linkage. The end of the linkage lever is combined with a control cylinder with a small amount of frictional force, and a delay switch of a paper input lever is provided between one side of the paper inlet and the control cylinder, and a micro switch connected to the main circuit controls The end face of the cylinder is provided with a notch to correspond to and control the spring arm of the micro-switch, and a protruding detent lever is provided in the middle of the control cylinder to correspond to and control the detent lever of the delay dial.

Although the above-mentioned drive delay stop device has a good effect, due to the large number of mechanical parts, the material and assembly costs are also high. However, the high cost of shredders can no longer survive in the market that competes with Japanese dramas. Only by reducing production costs can we meet the market price demand. Therefore, how to provide an improved drive delay stop device to reduce production costs and play a better use performance is an important subject of in-depth research and development. In addition, the conventional drive delay stop device is only applicable to the top-down paper feed mode (a u t 〇), but cannot be applied to the bottom-up paper feed mode (r e v) due to institutional restrictions. However, the timing of operating the eject mode usually occurs when the number of sheets fed by a single user exceeds the sheet capacity of the model, causing the motor to idle due to jam of the blade, because the motor and the blade are at this time. Due to the slower rotation speed, the normal chip removal efficiency is reduced. The paper scraps caught between the knife rods need to drive the chip removal function of the delay stop device to ensure the smoothness when re-feeding. [New content] The main purpose of this creation is to provide an airbag shredder drive delay stop device to reduce the number of parts and assembly labor by omitting many structures in traditional mechanisms, thereby reducing overall manufacturing costs and significantly improving market competitiveness . Another purpose of this creation is to provide a driving delay stop device of an airbag shredder, so that the driving delay stop device is suitable for both the paper feed mode and the paper ejection mode. By solving the defect that the traditional paper only applies to the paper feed mode,

In order to achieve the above object and solve the shortcomings of the conventional technology, the present invention discloses a driving delay stop device of an airbag type shredder, which is set on the base and is arranged on the inside of the paper shredder under the paper inlet. The driving delay stop device It mainly includes a micro switch, a rotary actuator, a pressure plate, and an airbag assembly. The rotary actuator is provided on an axle seat with an eccentric shaft. One end of the pressure plate is sleeved on the pressure spring of the micro switch, and the other end is The connecting neck is sleeved on the closed end of the airbag, so that when the pressure plate is pushed by the rotary actuator, one end can drive the pressure spring touch switch, while the other end presses the airbag inward, so that the airbag air is quickly discharged outward. ; When the rotary actuating member is pushed with the returning spring force of the micro switch compression spring and the returning force after the airbag is compressed, the air is sucked into the airbag at a relatively slow speed, so that the time for the airbag return volume to be fully filled is extended, and then delayed. The time that the compression spring trips off the micro switch makes the shredder drive motor continue to operate to facilitate the removal of shreds. In order to let your reviewers have a better understanding of this creation, Zizuo detailedly explains the creation as follows: [Embodiment] Please refer to the first figure for the configuration diagram of the drive-stop device of the airbag shredder and the second This is a perspective view of the appearance of the original creation.

Creation Instructions (4) As shown in the figure, the drive delay stop device mainly includes a micro switch 3, a rotary actuator 4, a pressure plate 5, and an airbag assembly 6, among which the rotary actuator 4 An eccentric shaft 41 is arranged on a shaft base 11 and triangular protrusions 42 and 43 are formed on the front and rear sides, respectively. The front protrusion 42 is located below the paper inlet 21, and the rear protrusion 43 is resisted against the pressure plate. 5 On the outer side, the pressure plate 5 is shown in the sectional view of the third figure. One end is sleeved on the compression spring 3 1 of the micro switch 3, and the other end is sleeved on the connecting neck 6 1 of the closed end of the airbag. 1. When the pressure plate 5 is pushed inward by the rotary actuator 4, the pressure plate 5 at one end can drive the pressure spring 3 1 to touch the switch 3 2, and the other end presses the airbag assembly 6 inward. Please refer to the fourth figure for a cross-sectional view taken along the third figure 4-4. The airbag assembly 6 includes a bellows-type airbag 61, a hollow rubber stopper 6 2 and a diaphragm 6 3. Among them, the rubber stopper 62 The head is fixed in a through hole 12 of an airbag seat, and the tube body is sleeved on the open end of the airbag 61 to connect the neck 6 1 2 so that the airbag 6 1 passes through a hollow rubber stopper. 62 and the through-slot hole 12 form an air circulation pipe with the outside world.
