And the limiting strip is hinged with a pressing plate, and the pressing plate can be pressed on the COF.

The one end that articulated department was kept away from to the clamp plate is inlayed and is had magnet, the platform adopts iron material.

One side of the pressing plate is provided with a pressing plate handle.

The platform is embedded with a lower knife edge at the position where the platform is sheared by the hand hay cutter, and an upper knife edge is correspondingly embedded on the hand hay cutter.

The upper knife edge and the lower knife edge are made of 45# die steel.

And a hand hay cutter handle is arranged at one end of the hand hay cutter, which is far away from the hinged position.

The platform is provided with at least 4 supporting legs, and the height of the supporting legs is larger than the thickness of the backlight plate.

The utility model provides a technical scheme's beneficial effect is: adopt the utility model discloses cutting the COF and can improving that machining efficiency is high, the incision is levelly and smoothly drawn one, greatly reduces workman intensity of labour, has simple structure, convenient operation, low in cost's advantage simultaneously concurrently.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The utility model discloses a COF guillootine, figure 1 to figure 5 show respectively that preferred embodiment's stereoscopic view, top view, elevation, side view, stereoscopic view. The COF cutting machine comprises a platform 1 for placing the COF, a limiting strip 2 is fixed on one side of the platform, a hand hay cutter 3 hinged with the platform is arranged at the end of the limiting strip, the limiting strip is perpendicular to the hand hay cutter, a backlight plate 4 is arranged at the bottom of the platform, and the backlight plate extends outwards and is located below the hand hay cutter.

When in use, a long COF to be cut is placed on the platform 1, and one side of the COF is abutted against the limiting strip 2, so that the COF is ensured to be vertical to the guillotine 3. After a COF is cut, the sliver COF is pushed to move to a position to cut the next COF. The COF is semitransparent, a light source (a backlight plate 4) is placed below the COF, so that the cutting position is favorably and appropriately observed, and the position of the COF is conveniently and timely adjusted. In the drawing, reference numeral 12 is a power terminal of the backlight, and reference numeral 13 is a power switch of the backlight.

Referring to the preferred embodiment shown in fig. 1, 2 and 4, a pressing plate 5 is hinged on the limiting strip 2 and can be pressed on the COF to flatten the curled COF, so that cutting displacement is avoided, and cutting precision is improved. In the drawings, 14 is shown a hinge for hinging the pressure plate.

In the preferred embodiment, a magnet 6 is embedded in one end of the pressure plate 5 away from the hinge joint, and the platform 1 is made of a ferrous material. When the pressing plate 5 is close to the platform 1, the pressing plate 5 will be attracted on the platform by magnetic force to press the COF, so as to avoid its curling. In order to lift the pressure plate 5, a pressure plate handle 7 is arranged on one side of the pressure plate 5.

In order to save the consumption of steel, in the preferred embodiment, the platform 1 is embedded with a lower knife edge 8 at the position where the platform shears with the hand hay cutter 3, and the hand hay cutter is embedded with an upper knife edge 11 correspondingly. The upper knife edge 11 and the lower knife edge 8 are made of 45# die steel (stainless iron).

In order to facilitate the operation of the fodder chopper, a fodder chopper handle 9 is arranged at one end of the fodder chopper 3, which is far away from the hinged position.

In a preferred embodiment, the platform 1 is provided with at least 4 supporting feet 10, the height of which is greater than the thickness of the backlight plate 4.

In a preferred embodiment, the pressure plate (5) is made of a soft silicon sheet. The soft silica gel sheet is softer, can avoid damaging the COF.

The foregoing examples are illustrative only and are not intended to be limiting. Any equivalent modifications or variations without departing from the spirit and scope of the present application should be included in the claims of the present application.
