Abstract
The utility model discloses a paper shredder with the function of the alarm stop due to the overflow of wastepaper, which comprises a single chip machine; wherein the single chip machine is connected with a motor through a motor control circuit, and also connected with an automatic paper-feeding control circuit, a manual control reverse circuit, a paper jam protection circuit and a display circuit; the utility model is characterized in that the single chip machine is also connected with a paper fullness control circuit. When the wastepaper bucket is full of wastepaper, the machine will implement the alarm stop to remind the people to clear up the wastepaper in time in order to avoid bringing the people troubles; at the same time, the door-open control circuit is also added, namely, when the machine door opens, the machine won't implement the alarm stop until the door is closed, and then the machine will normally work again, which therefore eliminates the existent potential safety problems.
Description
Technical field:
The utility model relates to a kind of shredder, especially has the shredder that function is shut down in paper scrap spill-over warning.
Background technology:
At present, all be provided with single-chip microcomputer on the known shredder circuit, be connected to by circuit for controlling motor such as relay and motor with single-chip microcomputer and join, join with single-chip microcomputer and also to be connected to automatic paper feed control circuit, manually to control circuit for reversing, paperboard holding circuit and display circuit, have automatic paper feed, manually control functions such as motor counter-rotating, paperboard protection; And all being provided with the shredded paper bits bucket that places the cutter shaft below on the structure, shredded paper bits bucket is covered in body by gate.Because shredder when work, gate is closed, and the operator does not also know the amount of shredded paper bits in the shredded paper bits bucket, and when the full and shredder of shredded paper bits also worked on, paper scrap will overflow in the paper scrap bucket, makes troubles to the user; In addition, when not outage of complete machine, and the operator opens gate when handling paper scrap, has paper to fall into suddenly as paper feed port, and then cutter shaft rotates, and exists injury operator's potential safety hazard.
Summary of the invention:
The utility model is in order to solve technical problem such as existing in prior technology paper scrap spill-over, provides a kind of and has the paper scrap spill-over and report to the police and shut down the shredder of function.
Technical solution of the present utility model is: a kind of shredder with paper scrap spill-over warning shutdown function; single-chip microcomputer is arranged; single-chip microcomputer joins by circuit for controlling motor and motor; joining with single-chip microcomputer also is connected to automatic paper feed control circuit, manually controls circuit for reversing, paperboard holding circuit and display circuit, it is characterized in that: also be connected to the full control circuit of paper with single-chip microcomputer.
Also be connected to the Men Weiguan control circuit with single-chip microcomputer.
The full control circuit of described paper is touch switch K1, and described touch switch K1 is provided with pressing board 1, is connected to rotating shaft 2 with the upper end of pressing board 1, and an end of rotating shaft 2 is poke rods 3, and poke rod 3 places the top of the fixed juncture 4 of touch switch K.
Described Men Weiguan control circuit is mounted in the magnetic switch K2 on the gate.
The utility model is to have increased the function that paper is completely reported to the police and shut down on the basis of existing technology, both when the paper scrap the paper scrap bucket in completely the time, and the machine shutdown of can reporting to the police, reminds people in time clears up paper scrap, the trouble of avoiding so bringing to people; Also increased the Men Weiguan control circuit simultaneously, both when the door of machine when opening, machine shutdowns of also can reporting to the police, after door shut, machine is operate as normal again, eliminates so existing potential safety hazard.
Description of drawings:
Fig. 1 is the schematic block circuit diagram of the utility model embodiment.
Fig. 2 is the concrete line map of the utility model embodiment.
Fig. 3 is the touch switch structural representation of the utility model embodiment.
The specific embodiment:
Below in conjunction with the description of drawings specific embodiment of the present utility model.As shown in Figure 1; single-chip microcomputer is arranged; single-chip microcomputer joins by circuit for controlling motor and motor, joins with single-chip microcomputer to also being connected to automatic paper feed control circuit, manually controlling circuit for reversing, paperboard holding circuit and display circuit, also is connected to full control circuit of paper and Men Weiguan control circuit with single-chip microcomputer.
Concrete circuit is as shown in Figure 2: single-chip microcomputer JP7 selects PIC16F676 for use, is connected to capacitor C 8, resistance R 44 with 8 pins of single-chip microcomputer, also is serially connected with resistance R 27, touch switch K1 and magnetic switch K2 simultaneously between power supply and 8 pins.Touch switch K1 is the sensor with sensing paper scrap amount, also is the full control circuit of paper; Magnetic switch K2 is installed on the gate, is the Men Weiguan control circuit.
Touch switch K1 concrete structure is as shown in Figure 3: be provided with pressing board 1, be connected to rotating shaft 2 with the upper end of pressing board 1, rotating shaft 2 is installed on the body, and pressing board 1 places the top of paper scrap bucket.One end of rotating shaft 2 is poke rods 3, and poke rod 3 places the top of the fixed juncture 4 of touch switch K.Magnetic switch K2 can be mounted in magnet, the tongue tube on gate, the doorframe.
Operation principle:
Paper scrap less than the time, pressing board 1 is hung vertically in paper scrap bucket top, poke rod 3 places the top of fixed juncture 4, does not join with fixed juncture 4.At this moment, touch switch K1 is not touched, and touch switch K1 is in long close point, and 8 pins on the single-chip microcomputer are high potentials, and circuit for controlling motor control motor is in holding state.After paper scrap was full, paper scrap touched pressing board 1 and rotates, and rotating shaft 2 drives poke rod 3 and rotates, join with fixed juncture 4, switch is in long the battle, and 8 pins on the single-chip microcomputer are electronegative potentials, single-chip microcomputer collects signal, and the order complete machine quits work, simultaneously the bright warning of yellow indicator lamp.In like manner, when Men Wei opens, magnet and tongue tube close together, the resistance of magnetic switch K2 is near zero, and the current potential of 8 pins on the single-chip microcomputer is high potentials; When door was opened, magnet and tongue tube distance was far away, the resistance approach infinity of magnetic switch K2, and 8 pins on the single-chip microcomputer are electronegative potentials, single-chip microcomputer collects signal, the bright warning of yellow indicator lamp simultaneously that quits work of order complete machine.
