After reason is finished, operating personnel press power switch, and cutting knife is moved playing surface to workbench, cuts paper.Cutting knife is in order to cutting
Compare thick cardboard and neat for tangent plane, the edge of a knife is sharp, and people when have maloperation unavoidably, if a hand is also
Below cutting knife, and another hand presses power switch, then cutting knife will switch to hand, causes security incident.
Utility model content
The utility model can prevent peace mainly solving the technical problems that provide a kind of safety guard of paper cutter
Full accident occurs.
In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of peace of paper cutter is provided
Full protection device, the paper cutter includes workbench and the cutoff knife rack above workbench, and the lower section of the cutoff knife rack is pacified
Equipped with cutting knife, the safety guard includes at least one light-irradiating lamp and the light-operated triode equal with light-irradiating lamp quantity,
The light-irradiating lamp is arranged on below cutoff knife rack, and the position of the light-irradiating lamp is higher than the blade edge position of cutting knife, each described to penetrate light
It is all provided with fluted on workbench immediately below lamp, the light-operated triode is in the groove, and the base stage of the light-operated triode is led to
Cross the emitter stage that resistance connects light-operated triode, the colelctor electrode connection main power source of the light-operated triode, the light-operated triode
Emitter stage connect cutter machine power input.
Wherein, the base stage of the light-operated triode is towards the light-irradiating lamp.
The beneficial effects of the utility model are：The situation of prior art is different from, the utility model passes through in paper cutter
Set on workbench and set the cutoff knife rack directly over light-operated triode, groove to be provided with light-irradiating lamp in groove, groove, if operation
The hand of member can then block the light of light-irradiating lamp, light-operated triode does not receive light, in high-impedance state, so as to cut below cutting knife
The power supply of disconnected cutting knife, cutting knife is stopped, if the hand of operator is not below cutting knife, light-operated triode receives light-irradiating lamp
Light, in low resistance state, so that the power supply of cutting knife is connected, in this way, so as to prevent security incident.
Brief description of the drawings
Fig. 1 is the structural representation of the safety guard of the utility model embodiment paper cutter.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
It is the structural representation of the safety guard of the utility model embodiment paper cutter refering to Fig. 1.The utility model
The paper cutter of embodiment includes workbench 1 and the cutoff knife rack 2 positioned at the top of workbench 1, and the lower section of cutoff knife rack 2 is provided with cutting knife
21, safety guard includes at least one light-irradiating lamp 3 and the light-operated triode 4 equal with the quantity of light-irradiating lamp 3, light-irradiating lamp 3
It is higher than the work immediately below the blade edge position of cutting knife 21, each light-irradiating lamp 3 installed in the position of the lower section of cutoff knife rack 2, and light-irradiating lamp 3
Fluted 11 are all provided with platform 1, light-operated triode 4 is in groove 11, and the base stage of light-operated triode 4 connects light-operated by resistance 5
The emitter stage of triode 4, the colelctor electrode connection main power source of light-operated triode 4, the emitter stage connection cutter machine of light-operated triode 4
Power input.In order to ensure the reliability of safety guard, in the present embodiment, the base stage of light-operated triode 4 is towards penetrating
Light lamp 3.
The operation principle of the safety guard of paper cutter of the present utility model is：Operator is pressed after power switch, such as
The hand of fruit operator is below cutting knife 21, then will necessarily block the light of light-irradiating lamp 3, then light-operated triode 4 does not receive light
Line, in high-impedance state, so that breaking between main power source and the power input of paper cutter, paper cutter power-off first can not work, and cut
The stopping of knife 21 is acted, if the hand of operator is not below cutting knife 21, light-operated triode 4 can normally receive light-irradiating lamp 3
Light, so as in low resistance state, be turned between main power source and the power input of paper cutter, paper cutter energization work, cutting knife 21 to
Lower motion progress cuts operation.
The quantity of light-irradiating lamp 3 and light-operated triode 4 can be set according to actual needs, when light-irradiating lamp 3 and light-operated three
When the quantity of pole pipe 4 is two or more, as long as there is a light-operated triode 4 not receive light, paper cutter can all be powered off.
By the above-mentioned means, the utility model sets light-operated by being set on the workbench of paper cutter in groove, groove
Cutoff knife rack directly over triode, groove is provided with light-irradiating lamp, if the hand of operator is below cutting knife, can block light-irradiating lamp
Light, light-operated triode does not receive light, in high-impedance state, so as to cut off the power supply of cutting knife, cutting knife is stopped, if behaviour
The hand of work person is not below cutting knife, then light-operated triode receives the light of light-irradiating lamp, in low resistance state, so as to connect the electricity of cutting knife
Source, in this way, so as to prevent security incident.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical fields, are similarly included in scope of patent protection of the present utility model.
