Abstract

A paper shredder comprises a top cover (1), a bottom cover, a cassette mechanism portion, an electrical portion and a refuse receptacle. One to three openings (2) are provided on the top cover. The electrical portion is designed with a fluid-damping time-delay switch (3). A plate (20) for adjusting a paper inlet port is arranged on the top cover. The fluid-damping time-delay switch prevents a column body from moving by a viscosity of the fluid in a cylinder thereof. Therefore, the time delay can be effectively achieved after paper shredding, which is convenient for completely cleaning away paper scraps stuck between cutters. Furthermore, the plate for adjusting the paper inlet port can effectively adjust an amount of the paper within a nominal thickness range of paper to be shredded or slightly above it, and a width of the paper inlet port within a range meeting safety requirements, which can effectively protect the paper shredder and prolong service life thereof.

Description

Shredder

Technical field

The utility model relates to the field of office equipment, in particular to the field of office paper pulverizing equipment, in particular to a paper shredder with a delay switch. Background technique

The Chinese utility model patent document with the patent number 01243131 describes a conventional shredder including a face cover, a bottom cover, a movement part, an electronic part and a trash can, wherein the cover has 13 ports, and the 13 ports respectively For the paper feed port, into the disc mouth or into the credit card port. The Chinese utility model patent document with the patent number 87205671 describes that the electronic part is often designed with a delay function, so that after the paper is shredded, the motor still works for a period of time to facilitate the removal of the shredded paper between the knives. This kind of delay function is often divided into mechanical and electronic delays, high electronic delay cost, simple mechanical delay structure and low cost. Therefore, in the shredder industry, especially the AC motor, the line is simple. For shredders, mechanical delays are especially needed inside to reduce costs. 5匪, The entrance of the shredder is usually a plastic material in one piece, in order to save the cost of the mold, the entrance is a two-piece plastic sheet. Otherwise, the mold is easy to break and damage, but it can't be too big. It will hurt the child's hand and damage the machine too much, and it does not meet the requirements of safety regulations EN60950-1/EN294/UL60950-1.

Utility model content

In order to solve the above problems, the utility model provides a paper shredder with a fluid damping daily delay switch, which can effectively achieve the purpose of delay, so as to facilitate the removal of the scraps of paper jam between the cutter bars.

The utility model provides the following technical solutions: A new type of shredder, including a cover, a bottom cover and a movement a portion, an electronic portion and a trash can, wherein the cover has 1 to 3 ports, wherein the electronic portion is designed with a fluid damping daily delay switch, and the cover is provided with a paper inlet adjustment plate .

The fluid damping daily delay switch comprises a housing, a cylinder, a cylinder, a fluid, a rotating shaft and a touch switch, wherein the cylinder is filled with the fluid, and the cylinder is a piston in the cylinder. Exercise, swing or turn. The cylinder can be added with a rotating shaft or a rotating shaft.

The touch switch can ensure the operation of 2~3 ports at the same time. The paper inlet adjusting plate is a piece of movable plastic piece or a piece of movable plastic piece or hardware. The paper inlet adjustment plate is adjusted by screws.

The beneficial effects of the utility model are as follows:

First, a fluid damping daily delay switch is designed so that after the paper is shredded, the motor can still work for a period of time to facilitate the removal of the shredded paper between the knives.

Secondly, the paper inlet adjustment plate is designed to effectively adjust the amount of shredded paper in the range of the rated shredded paper thickness or slightly increase. When the inlet width meets the safety requirements, the shredder can be effectively protected and the life of the shredder can be extended. .

The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

As shown in Figure 1, only two entries are shown, but one or three ports can be implemented by adding or subtracting one port and the corresponding electronic control portion.

As shown in FIG. 2 and FIG. 3, a novel shredder has an electronic part designed with a fluid damping daily delay switch 3, wherein the fluid damping daily delay switch 3 includes a housing 31 and a cylinder a 32. , cylinder b 33, cylinder 34, fluid 35, shaft 36 and touch switch 37. In the case of ensuring the working time of 2-3 ports, it can be realized by adding the disc rotating shaft 39 to the cylinder or increasing the rotating shaft 36. The cylinder body a 31, the cylinder body b 32 is provided with the fluid 35, and the cylinder body 34 performs piston movement, swinging or rotation in the cylinder body. The cylinder block a 31 and the cylinder block 32 form a cylinder body, and the cylinder body is filled with fluid, mainly butter and damping grease, and the cylinder 34 rotates in the cylinder body, when paper or optical disc or credit card passes through the shredded paper inlet of the cover 1 When the broken disc inlet contacts the rotating shaft 36 or the disc rotating shaft 39, the rotating shaft 36 or the disc rotating shaft 39 rotates, and the fulcrum 38 thereon contacts the touch switch 37, so that the whole machine can be lifted, when the paper or the disc or the credit card is broken. The force of the contact of the switch 37 is activated to rotate the rotating shaft 36 or the rotating shaft 39, and the rotating shaft 36 or the rotating shaft 39 and the cylinder 35 are connected together, so that the cylinder 34 moves in the cylinders a, b 31, 32, because The liquid in the cylinder is viscous, thus hindering the movement of the cylinder 34, thereby achieving the purpose of delaying, and removing the paper scraps stuck between the knives. When it is 2-3 ports, the delay switch adopts the same one. By adding the disc rotation shaft 39 or increasing the rotation shaft 36 on the cylinder, a touch switch is shared, which greatly saves the cost.

As shown in FIG. 4, a paper inlet adjustment plate 20 is designed on the new paper shredder. The paper inlet adjustment plate 20 is a plastic piece that is fixed by two conventional entrances, and a piece of movable plastic piece is separated. It can be a metal piece, as the paper inlet adjusting plate 20, in order to control the inlet width as much as possible so that the rated amount of shredded paper can pass smoothly, by adjusting the screw 21, so as to be the paper inlet adjusting plate 20 Move, so that the overall shredded paper inlet width is controlled to the same or more than 1 n sheets of the rated shredded paper thickness, and the value of n must ensure that the inlet width of the whole machine meets safety regulations, such as EN60950-1/EN294/UL60950-1. Theoretically speaking, the smaller the value of n, the smaller the damage to the shredder. For example, a shredder with a rated amount of shredded paper of 8 sheets puts 9 sheets of paper at the entrance. By moving the paper inlet adjustment plate 20, 9 sheets of paper can be smoothly taken out, and the screws 21 are locked. The entrance can not effectively pass through 11 sheets of paper by artificially pressing the paper in actual use, which effectively protects the shredder.

As shown in Fig. 5, the shredder adopts the paper inlet adjusting plate 20 and the time delay switch 3 at the same time, because the line using the above delay switch 3 is often a simple line, when the paper exceeds the rated amount of shredded paper, the line usually does not have The function of preventing the stalling is always blocked by the motor itself, which damages the rotating system of the whole machine, which is not conducive to the life of the whole machine. Therefore, adjusting the width of the inlet will inevitably produce better results.

While the preferred embodiment of the present invention has been disclosed for purposes of illustration, it will be understood by those skilled in the art Spirit and scope.
