Description

  The present invention relates to a shredder, and more particularly to a press mechanism for an automatic shredder.

  The shredder crushes the paper or paper loaded by the shredder cutter of two roller pairs. Most of the shredders currently used are manual shredders, and the user needs to divide the documents to be discarded into small portions and put them into the shredder entrance. When crushing multiple stacked documents, the user needs to spend a lot of time separating and loading the paper by the shredder, wasting valuable time.

  Some companies have developed a type of automatic paper shredder, but the paper feed efficiency is not very high and the gripping ability is not strong. The principle is similar to that of a printer. The paper is wound around the shredder cutter one by one by the winding roller, and each piece of paper passes through the winding roller in a nearly contiguous manner. If not, the second sheet is not crushed, the efficiency is low, and it is required to discharge the crushed paper properly, and the demand for cleanliness of the crushed document is high.

  The built-in automatic paper feed mechanism has greatly improved the paper feed efficiency and grip ability compared to the printer-type shredder, but this type of shredder needs to press the paper against the paper feed roller, so the shredder's It is necessary to provide a press mechanism on the upper cover. However, the current shredder is inconvenient because the user needs to manually operate the press mechanism when inserting paper.

  In view of this, there is a need to provide an automatic shredder press mechanism that is convenient to operate on the problem of inconvenient operation of the conventional shredder press mechanism.

  The press mechanism of the automatic shredder includes a press plate that presses the paper toward a paper feeding device that sends the paper to be cut to the shredder cutter, a first fixed plate that is rotatably attached to the body, and a second fixed that is fixed to the body. A plate, a link mechanism provided between the press plate and the first fixed plate, and the link mechanism directs the press plate toward the paper feeding device as the first fixed plate rotates. The paper is moved between a pressing position where the paper is pressed and a retracting position where the paper to be cut is retracted so that the paper to be cut can be put into the paper feeding device.

The apparatus further includes an upper cover fixedly connected to the first fixed plate and rotatably attached to the body.

The link mechanism maximizes a distance between the press plate and the first fixed plate when the first fixed plate rotates to a position orthogonal to the second fixed plate, and the first fixed plate When the plate rotates to a position parallel to the second fixed plate, the distance between the press plate and the first fixed plate is minimized.

The link mechanism is resilient element, the first link, second link, third link, and a fourth link, the first guide slot is provided on the press plate, one end of the first link in the first guide slot is slid connected, the other end of the first link is rotated connected to the first fixing plate, wherein one end of the resilient elements are rotated connected to the first fixing plate, and the other end is the first link of the resilient element is rotational connection, one end of the second link is rotated connected to the first link, the other end of the second link is rotated connected to the press plate, the second guide slot is provided at one end of said third link the fourth link end third guide slot is provided in the, said pin shaft is provided on the first link, said pin shaft is in said second guide slot Is slid connected, the other end of the third link is slid connected in said third guide slot, wherein the third link is rotated further connected to the first fixing plate, the fourth other end the second link Rotating connection with fixed plate. Further, when the upper cover starts to open, the fourth link rotates the third link in conjunction with each other, and when the third link rotates, the first link is caused to move in the opening direction. The elastic part is compressed, the press plate is caused by the first link, and the second link keeps the press plate from returning in the closing direction. When the upper cover is opened to a position where the first fixed plate is parallel to the second fixed plate, the fourth link pulls the third link, and the first link is moved to the first fixed plate side. The elastic part is compressed and enters a dead center position, and the press plate is raised toward the first fixed plate in parallel with the first fixed plate .

  Preferably, the pin shaft has a cylindrical shape.

  The link mechanism has a pressing position where the press plate is pressed against the paper feeding device as the first fixed plate is rotated, and a retreating position where the paper to be cut is retracted so that the paper can be fed into the paper feeding device. Move between. For this reason, the automatic shredder press mechanism is convenient to operate.

  By fixedly connecting the upper cover to the first fixing plate, an automatic shredder that is more convenient to operate can be provided. That is, when the automatic shredder opens or closes the upper cover, the press plate is driven by the link mechanism. When the upper cover is opened, the press plate is caused by the linkage mechanism and opens with the upper cover. When the paper is loaded and the upper cover is closed, the press plate is opened by the link mechanism and pressed smoothly onto the paper, and the link mechanism generates pressure and simultaneously presses the paper firmly to the lower paper feeder. For this reason, the automatic shredder press mechanism is convenient to operate.

It is a figure which shows an automatic shredder. It is a figure which shows the automatic shredder at the time of opening an upper cover by a fixed angle. It is a figure which shows the automatic paper shredder at the time of opening an upper cover 90 degree | times.

  FIG. 1 shows an automatic shredder. The automatic shredder generally includes parts such as a shredder cutter 10, a paper feed mechanism 11, and a press mechanism. The paper feed mechanism 11 is provided above the shredder cutter 10, and the press mechanism is provided above the paper feed mechanism 11. The paper feed mechanism 11 is configured to feed paper to be cut to a shredder cutter, and includes a paper feed roller.

  The press mechanism includes a first fixed plate 120 rotatably attached to an automatic shredder body (corresponding to the body), a second fixed plate 20 fixed to the body, and a press plate 16 that presses the paper toward the paper feeder 11. Two link mechanisms are included. The two link mechanisms are arranged on both ends of the first fixed plate 120 and the rotation shaft of the upper cover 12. In addition, what is necessary is just to provide at least 1 link mechanism. The connection method of the two link mechanisms is the same. Each link mechanism includes an elastic part 13, a first link 14, a second link 15, a third link 17, and a fourth link 19.

  The link mechanism includes a pressing position (a position shown in FIG. 1) for pressing the paper toward the paper feeding device 11 as the first fixed plate 120 rotates, and a paper feeding device for cutting the paper. 11 is moved between the retreat positions (positions shown in FIG. 2, preferably the positions shown in FIG. 3) so that they can be put into the vehicle.

  The press mechanism of the automatic shredder further includes an upper cover 12 fixedly connected to the first fixed plate 120 and rotatably attached to the body.

  The link mechanism maximizes the distance between the press plate 16 and the first fixed plate 120 when the first fixed plate 120 rotates to a position perpendicular to the second fixed plate 20 (see FIG. 1). When the first fixed plate 120 is rotated to a position parallel to the second fixed plate 20, the distance between the press plate 16 and the first fixed plate 120 is minimized (see FIG. 3).

  The first fixing plate 120 is fixedly connected to the upper cover 12 of the automatic shredder, and the upper cover 12 can rotate 90 degrees around the automatic shredder body.

When the upper cover 12 opens at a certain angle, the fourth link 19 rotates the third link 17 in conjunction with it, and when the third link 17 rotates, the first link 14 is caused to move upward, and the elastic part 13 is moved. Once compressed, the press plate 16 is caused by the first link 14 and the action of the second link 15 is to keep the reversal from occurring during the movement of the press plate 16.

  FIG. 3 shows an automatic shredder when the upper cover is opened 90 degrees. When the upper cover 12 is fully opened to the 90 degree position, the fourth link 19 pulls the third link 17 and pulls the first link 14 close to the position of the first fixing plate 120, and the elastic part 13 is completely compressed. And enter the dead center position. The press plate 16 is raised in parallel to near the position of the first fixed plate 120.

  When the automatic shredder opens or closes the upper cover 12, the press plate 16 is driven by a link mechanism. When the upper cover 12 is opened, the press plate 16 is caused by the link mechanism and opens together with the upper cover 12. When the paper 30 is loaded and the upper cover 12 is closed, the press plate 16 is opened by the link mechanism and is smoothly pressed onto the paper 30. The link mechanism generates pressure, and at the same time, the paper 30 is moved downward by the paper feed mechanism 11. Press firmly against the paper feed roller. For this reason, the operation of the press mechanism of the automatic shredder is convenient.
