Description

A kind of knife lock device of miniature paper cutting machine

Technical field

The utility model relates to the paper cutter locking device, particularly miniature paper cutting machine knife rest locking device.

Background technology

A kind of universal paper cutter such as Fig. 1 show, be fixed with left riser 20 and right riser 9 at main platen 1 left and right side, be connected with entablature 19 between left and right riser, tool-post structure 5 rollers that two ends join 7 that downside is installed cutting knife are embedded in the skewed slot of left and right riser, tool-post structure can be moved up and down along skewed slot by roller, and 3 on main motor 2 cranks bar 4 upper ends repeatedly are connected with tool-post structure 5 with adjustment screw 8 through contiguous block 6.Main motor rotating band moving knife support body and cutting knife that downside connects thereof the realization cut paper that moves up and down.Paper cutter is a kind of implement of highly dangerous, though taked multiple safety measure at present, as bimanualness, configuration infrared inductor, safty shield or the like, but because service condition varies, corrective maintenance is perfect not to the utmost, safety device is damaged, reasons such as user's maloperation, and the incident that causes paper cutter to hurt sb.'s feelings often has generation.

Summary of the invention

The utility model will solve the problem of present paper cutter processing ease generation casualty accident, and the knife lock device of a kind of miniature paper cutting machine of the present utility model is provided for this reason, and this apparatus structure is simple, and is easy to operate, improved the paper cutter processing safety greatly.

For addressing the above problem, its special character of the technical solution adopted in the utility model is by comprising hook, pivot, hook pin, electromagnet, can control the microswitch of main motor forms, described pivot is fixed in the entablature of paper cutter framework, pivotly join described hook on the pivot, hook is a slotted hole with the mating holes of pivot, slotted hole top is embedded with movable bolster, described pivot is positioned at the slotted hole bottom and contacts with movable bolster, the gib head downside of hook has the inclined-plane, described hook pin is fixed in the tool-post structure of paper cutter, the gib head of described hook corresponding to this hook pin and hook can clasp during return in this hook pin, be connected with return spring on the described hook, described electromagnet is fixed in described entablature, electromagnet core is connected with described hook, the pulling hook rotation of contracting in electromagnet is switched on its iron core makes the hook gib head break away from described hook pin, and described microswitch is fixed in described entablature, and the circular arc end face that this microswitch push-button is close to described hook upper end under the normality makes microswitch be in closure state.

Should neonychium be installed at the gib head place of described hook.

Described return spring is preferably extension spring, and the one end is connected in hook, and the other end is fixed in right riser or entablature.

Described electromagnet core is connected with hook and is meant that electromagnet core is connected with linking up with through brace.

Movable bolster pressurized in the utility model can be compressed distortion when surpassing rated pressure.Movable bolster can be the plasticity cushion block, also can be stage clip.The one side that movable bolster contacts with described pivot has wear-resisting lining.

The described pivot outer end that pivotly joins hook has the step that radially extends out, and this step becomes the retaining platform and can avoid hook to deviate from.

During electromagnet no power in the utility model, hook hook under the return spring effect tool-post structure on hook pin, tool-post structure can not fall, paper cutter is locked.

When the operator prepares to open paper cutter, contact respective switch simultaneously with both hands, the electromagnet energising, pulling hook rotation one angle that contracts in the iron core, the hook gib head is thrown off the hook pin on the tool-post structure, and tool-post structure falls, and realizes cut paper.When cut paper back tool rest body upwards returns, the electromagnet outage, hook backswing under the return spring effect, the described inclined-plane that the hook pin on the tool-post structure propped up and slipped over the hook bottom hooks the hook gib head, and paper cutter is locked.

The utility model is owing to pivotly joined hook through pivot on the entablature, hook is provided with return spring, being provided with its iron core of electromagnet is connected with hook, be provided with and be close to hook upper surface and be in closure state under its button normality of microswitch, hook is a slotted hole with the mating holes of pivot, slotted hole top is embedded with movable bolster and contacts above the pivot, tool-post structure is provided with and links up with the hook pin that cooperates, so during the electromagnet no power in the utility model, hook hooks the hook pin on the tool-post structure under the return spring effect, tool-post structure is lockable and can not falls, have only as the operator and prepare to start paper cutter to after the electromagnet energising, just can make the hook pin on the hook disengagement tool-post structure, make paper cutter enter duty; When appearring in paper cutter, control program makes mistakes, abnormal conditions such as computer crash, cause the paper cutter unnormal unlocking, do not switch on because of electromagnet this moment, hook still hooks the hook pin on the tool-post structure, the whereabouts by force of its tool-post structure of paper cutter of unnormal unlocking is moved towards to apply the additional impact pulling force to hook, the slow piece compressive deformation of activity on hook slotted hole top moves down the hook small distance, originally being close to microswitch push-button and this upper surface of linking up with the upper surface throws off, control the microswitch outage of main motor, close main motor power by force, main motor stops operating, and paper cutter is just locked, thereby guarantees user's safety.
