In view of the defects in the prior art, the present application provides an electric rubber cutting knife, which can not only protect the rubber tree from being cut, but also improve the tapping speed, is light and easy to operate, and reduces the requirement of the rubber tapping operation on the rubber skill.

The present application provides an electric tapping knife comprising: a rotary cutter set, a protection seat, a drive mechanism and a base; the rotary cutter set is disposed at a lower portion of the base, the rotary cutter set includes a blade holder and a shaft, the shaft One end of the rod is connected to the base, and the other end of the shaft is connected to the center of the blade seat. The bottom of the blade seat is provided with a plurality of bottom edges, and the side of the blade seat is provided with a plurality of side edges, and the bottom edge and the side edge are Correspondingly, each of the bottom edges is connected with the corresponding side edge and forms a certain angle; the protection seat is disposed on the side of the machine base against the rotary knife set, and the bottom surface of the protection seat is provided with a bottom reference, and the side of the protection seat is disposed The side reference is perpendicular to the side reference. When cutting, the bottom reference of the protection seat rests on the bottom surface of the rubber cutting surface to control the skin depth of each cutting, and the side reference of the protection seat rests on the side of the rubber cutting surface. The thickness of the skin for each cut is controlled; the drive mechanism is mounted in the housing, and the drive mechanism is used to drive the rotation of the rotary cutter.

The present application drives the rotary cutter set to rotate by the drive mechanism, and then the rubber cutting surface of the rotary cutter is rotated by the side edge and the bottom edge of the rotary cutter set. Since the rotary cutter set is provided with the bottom edge and the side edge, the bottom edge of the rotary cutter set is used for Cutting the bottom surface of the rubber cutting surface (ie, the cross section of the bark), the side edge of the rotating knife set is used to cut the side of the rubber cutting surface (ie, the circumferential surface surrounding the trunk), and the side reference of the protective seat is pressed against the trunk when cutting The surface, through the limit of the protection seat in the radial direction, to keep the thickness of the side cutting of the rotating knife group consistent with the previous cutting, thereby protecting the rubber tree from being cut, and cutting the bottom reference of the protection seat against the bark when cutting The cross-section, through the limit of the protection seat in the axial direction, to keep the height of the cutting edge of the rotary knife set in line with the previous cutting, thereby effectively controlling the depth of the skin for each cutting, therefore, when the worker is operating, It is only necessary to press the side reference of the protection seat against the trunk and the bottom reference of the protection seat against the cross section of the bark and push along the cutting line, thereby greatly reducing the difficulty of the tapping operation. Low-skilled workers' demands, the workers more easily get started operation, reduces training costs, while improving tapping speed.

Further, the middle portion of the bottom of the protection seat is provided with a notch which divides the bottom reference into two step faces of different heights, and the blade holder of the rotary blade set is disposed between the two step faces of the bottom reference. Since the heights of the two step faces are different, the blade holder is disposed between the two step faces, so that the bottom reference and the rubber cutting face are more conformable.

Further, an inclined chamfer avoidance is provided between the side reference and the bottom reference. By setting the chamfering to avoid emptying, it is possible to prevent the protective seat from compressing the latex tube during cutting to reduce the glue production.

Further, the relative position between the protection seat and the blade holder can be adjusted, and the height of the bottom edge of the blade holder is exposed to the bottom reference by adjusting the relative position between the protection seat and the blade holder, thereby adjusting the consumption of each cutting. The depth of the skin is adjusted by adjusting the relative position between the protection seat and the blade holder to expose or retract the side edge of the blade holder to adjust the thickness of the skin for each cut. Since the position of the protection seat can be adjusted, in the normal tapping work, the operator should ensure that the thickness of the rubber tree water sac to the trunk is within the specified range. If the water sac is too thin or cut directly, the cut rubber tree will be formed. Phenomenon, by adjusting the protection seat so that the side edge is retracted into the side reference of the protection seat, the thickness of the skin can be reduced. If the water skin is too thick, the amount of glue will be affected. By adjusting the protection seat, the side edge is exposed to the protection seat. The side reference surface can increase the thickness of the skin. Through such adjustment, the rubber tree can be protected from being cut while ensuring the rubber output; and by adjusting the distance of the bottom edge to expose the bottom reference, Adjust the skin depth of each cut.

When adjusting the position of the protection seat, firstly, the locking screw needs to be loosened. Since the fixing seat is fixed, when the leather depth adjustment screw is turned, the skin depth adjustment screw moves up and down, so as to protect the skin by the depth adjustment screw. The seat moves up and down, and then adjusts the height of the bottom edge to expose the bottom reference.

Further adjusting the thickness of the skin for each cutting, the side edge 14 of the blade holder 11 is exposed or retracted into the side reference 22 by adjusting the relative position between the protection seat 2 and the blade holder 11, thereby adjusting the thickness of each cut. . In the normal tapping work, the operator should ensure that the thickness of the rubber tree water sac to the trunk is within the specified range. If the water sac is too thin or cut directly, the rubber tree will be cut, and the protective seat 2 is adjusted. The side edge 14 is retracted into the side reference 21 of the protection seat 2 to reduce the thickness of the skin. If the water skin is too thick, the amount of glue is affected.
