Description
Technical field
The present invention relates to cutting equipment, be specifically related to a kind of cutter shield.
Background technology
Table saw equipment, in order to ensure the safety of cutting process, is provided around protective cover at cutting blade.Protective cover is generally connected and composed by retaining frame and backplate, wherein, conventional U-shaped integral type shield structure, protection blind area is easily produced when blade is in heeling condition；And the shield structure of the double-disk after improving, when the state of blade tilt, the blade of both sides interlocks up and down, along with the propelling of material can adjust position at any time, follows up in time, it is achieved that comprehensive, non-blind area protection.
Backplate typically uses the mode of handing-over to be flexibly connected with retaining frame, when the state that blade is in vertically or gradient is little, in cutting process, backplate by after the thrust of material, backplate can centered by hinge point flexible rotating；But, when blade is in heeling condition, such as during blade tilt 45 degree, backplate tilts together with blade with retaining frame, and now, material is inconsistent to the thrust direction of backplate and the direction of motion of backplate, owing to being in the backplate below retaining frame, the phenomenon got stuck easily occurs, hinders being smoothed out of cutting process, affect work efficiency.
Summary of the invention
Present invention is generally directed to the problem that existing cutter shield exists stuck point, a kind of double-disk, non-blind area, cutter shield without stuck point are invented, this cutter shield adds boosting pulley in retaining frame, make backplate without stuck point in motor process, it is achieved thereby that backplate any angle all can smoothly on the effect lifted.
The present invention above-mentioned technical problem is that and be carried out by the following technical programs: a kind of cutter shield, including main retaining frame, the both sides of main retaining frame are provided with backplate, being connected with knife plate of the tail end of main retaining frame and cutting machine, it is characterized in that, the afterbody of main retaining frame is provided with articulated elements, is flexibly connected with the backplate of both sides by this articulated elements, and the front end of described main retaining frame, side towards backplate are provided with boosting pulley.
Backplate relative to main retaining frame define can being hinged of flexible rotating, then during charging and the material returned, the backplate of both sides can the most independently and flexibly rotate, and above lifts or falls, and is in optimal protective position all the time.
As preferably, described boosting pulley is connected with main retaining frame by straight pin.
As preferably, at the connecting portion of boosting pulley Yu main retaining frame, being arranged to the mounting groove of indent according to the contour shape of boosting pulley and straight pin, the edge of boosting pulley is exposed at outside the plane at place, main retaining frame side.
As preferably, described backplate extends to the front end of main retaining frame from the rear end of main retaining frame, and the length of backplate is more than the length of main retaining frame, and the plate face of backplate can contact with the marginal portion of the boosting pulley being exposed at outside main retaining frame side.
After increasing boosting pulley, due to boosting pulley edge relative to the side of main retaining frame be protrude, so, the plate face of backplate can be touched with the side edge of boosting pulley, forms Structure deformation, and frictional force is little, when backplate is when heeling condition is by the thrust of material, by the auxiliary rolling action of boosting pulley, backplate can overcome the most easily because of angle tilt, the problem of the retard motion caused such as excessive that rubs, it is achieved smooth rotation, on lift.
As preferably, the interlude of described main retaining frame is provided with a horizontal locating shaft, and on the backplate plate face of the described left and right sides, the position corresponding with locating shaft is provided with positioning slide, and the two ends of locating shaft respectively penetrate in the positioning slide of the left and right sides.
The purpose herein arranging locating shaft and positioning slide is, when backplate rotates upwardly and downwardly, can control, position the position of backplate, especially when blade is in obliquity, backplate also must inclination in equal angular, if the most only by the connection of backplate rear end with main retaining frame, and there is no the constraint of locating shaft and positioning slide, so backplate can extend out towards the direction of gravity, increases friction when rotating, the flexibility ratio that impact rotates.
As preferably, described positioning slide extends to backplate lower limb from backplate top edge, the square opening of both sides horizontal expansion to the left and right it is provided with in the lower end of positioning slide, and, lower end at positioning slide arranges location spring, location spring is arranged to up-narrow and down-wide shape, positions the opening up of spring, and the spring on opening part both sides inside contracts formation narrow entrance openings.
Owing to the rotation of backplate is the most smooth and easy, locating shaft move along positioning slide during also almost without friction, so, in order to meet in practical work process, it is sometimes desirable to backplate is positioned, avoids its situation about arbitrarily rotating, location spring is added in the lower end of positioning slide, when locating shaft slips into lower end under positioning slide, and it clamp-ons in turn, owing to location spring has elasticity, and in conjunction with up-narrow and down-wide shape design, must by locating shaft card wherein；If being complete location, needing to discharge backplate, the most only need to use slightly larger external force and just locating shaft can be pulled out in the spring of location.
In sum, the present invention compared with prior art has the advantage that
The present invention uses the structure of biplate backplate, it is achieved that non-blind area is protected；The present invention is on the basis of double-disk protective cover, add the design of boosting pulley, under the auxiliary of boosting pulley, make backplate without stuck point in motor process, reached backplate angle of inclination can also smoothly on the effect lifted, thus eliminate the situation that cutting work is obstructed often, be conducive to improving work efficiency.
