Description

A kind of safety cutting device for material
Technical field
The present invention relates to materials processing device, especially a kind of cutter sweep, the cutter sweep of such as flexible material.
Background technology
Cutter sweep is widely used in material processing field.The cutting that cutter sweep often adopts blade reciprocating and completes material.
But in the process of cutting, cut material often leaves faint residual connecting portion after having cut.This all brings adverse effect to crudy and follow-up procedure of processing.Especially to the cutting such as with certain flexible flexible material, owing to not easily cutting off material completely in the slow motion of trickle position blade, the residual company of material is caused thus.
And if merely increase the speed of service and the cutting force that equipment performance such as accelerates blade to cutter sweep, this significantly will increase cost and increases the complexity of equipment thus be unfavorable for safeguarding.
Summary of the invention
The object of the present invention is to provide a kind of safety cutting device for material, it can overcome defect of the prior art.
According to a kind of safety cutting device for material of the present invention, comprise the support body being fixedly installed clamshell, described support body is provided with cutting knife bar slidably, described cutting knife bar is included in the cutter head in order to perform cutting at left end place, be positioned at the recess at the upper side place of described cutting knife bar, be positioned at right side protuberance and the left side protrusion at described cutting knife bar downside place, and the engagement end portion in order to engage with described clamshell at right-hand member place, described engagement end portion also engages with top compression elasticity part thus can by the described engagement end portion bias voltage of described cutting knife bar against described clamshell, be provided with accordingly with recess in described support body and can slide up and down and pressed by elastic top pressing spring top and press to the clapboard of described cutting knife bar, the lower end of described clapboard is the lozenges in order to coordinate with the inclined-plane, left side of described recess, also be provided with in described support body by the drive motors of external power source, the screw flight driven by described drive motors is combined with the screw drive slide block led by guide-track groove, the upper end of described screw drive slide block is stretched between the described right side protuberance and left side protrusion of described cutting knife bar, and described recess bottom is provided with has the flexible feeler in order to contact with described clapboard, thus, when engagement end portion described in original state by described top compression elasticity part bias voltage against described clamshell time, described cutting knife bar is in retracted mode, when needs carry out cutting operation, described drive motors runs thus makes described screw drive slide block to left movement to make described upper end to engage with described left side protrusion and to make described cutting knife bar move left, and described cutter head and cut material effects also start to cut, when described cutting knife bar continues to left movement and when making described recess start to engage with the corresponding wedge surface of described clapboard, the elastic reaction of described elastic top pressing spring makes described clapboard to left movement, described cut material is completely severed described cutting knife bar acceleration, when described cut material is completely severed, described clapboard slides and contacts with described feeler, signal transmission is given described drive motors by described feeler, thus described drive motors antiport drives described upper end to engage with described right side protuberance, and described cutting knife bar is moved right thus makes described recess depart from the joint with described corresponding wedge surface, described cutting knife bar returns described original state so that perform next cutting operation under the effect of described top compression elasticity part, the outer face of described clamshell left end is rotatably mounted with preventing cutter tool protecting cover, and described preventing cutter tool protecting cover is positioned at above described cutter head, described cutter head lower end has the inclined-plane matched with described cutter head, and described preventing cutter tool protecting cover can protect described cutter head when described cutting knife bar is in retracted mode.
In the present invention, owing to being provided with the cutting knife bar that the hard to bear screw drive block of energy drives, therefore, it is possible to drive blade movement thus the cutting operation of execution material.And two stressed protuberances of dividing right and left are set on cutting knife bar, hold the drive division driving threaded block therebetween, thus make described threaded block can drive the side-to-side movement of described cutting knife bar, allow again described cutting knife bar and described screw drive block to have spacious momentum to a certain degree, allow knife bar to move in certain free degree relative to screwed hole; And, when being provided with clapboard by elastic top pressing spring top pressure with the cut-out being near completion material at cutting blade, adopting impact cutting movement, thus temporarily accelerate the speed of service of blade, avoid the residual company of material after cutting thus.The energy of this impact cutting movement comes from motor equally.Thisly allowed asynchronously can allow the unexpected accelerated motion of described cutting knife bar and not need the lifting and the replacing that increase extra drive system or power source motor is carried out to performance.The problem of residual company after whole device can effectively solve material removal, and safe and reliable to operation, easy to use.
