Embodiment 1

[0031] like Figures 1 to 7 As shown, the present invention provides a splinger for a splitter, including a frame 1 that can move on the spiral rail 14, and a lower portion of the frame 1 is connected to a restricted slide 2; a rotation in the limit slide 2 is provided. The worm 3 and the slidable rack 4 are provided with a cutter 11 in the end of the rack 4; a scalabus 4 is provided on the rack 4, which is used to adjust the scalable elastic teeth 5, the rack 4 of the cutter. There is also a fixed tooth teeth 6 for pushing the tool 11 advancement and retreat, the elastic tooth teeth 5 and the fixed tooth teeth 6 are driven to drive the worm 3 by the drive connection of the rack 4 by the worm 3 to rotate the worm 3. The drive rack 4 performs a straight forward and retreating movement; so that the cutting rubber cutter 11 performs a knife and a cutter; the limit slide 2 is provided with a rotational unlocking apparatus 7 and a rotational unlocking device 7 with the rack 4. The elast...

Embodiment 2

[0036] like Figures 1 to 7 As shown in connection with the technical solution of Example 1, in the present embodiment, the spring groove 21 is provided on both sides of the limit slide 2, and the spring groove 21 is provided with a first spring 12, and the end portion of the rack 4 is provided. There is a projection 42 that slides to the first spring 12 to reverse the rack 4 slid out by the first spring 12 to facilitate the rack when the elastic teeth 5 shrink into the rack 4. 4 Bounce under the action of the first spring 12 to make the teeth quickly abut the worm 3 to achieve a quick-cutting tool of the cutter 11, and the cutting method of cutting the knife is returned to the bottom, that is, the tool 11 from below When the upper wrap is replaced by a spiral cut back, the quick closing can prevent the cutting of the cutter 11 to the bark.

[0037] Specifically, the rotation unlocking apparatus 7 includes a bracket 71, a hinge 72, a right angle die 73, and a restricted rod 74, and...

Embodiment 3

[0041] like Figure 5 and Figure 7 As shown in connection with the technical solution of Example 2, in the present embodiment, the slider 83 includes a first slider 831 and a second slider 832, and the first slider 831 is connected to the first elastic lock teeth 81, and the second slider. 832 is connected to the second elastic lock teeth 82; the first slider 831 is threaded with the adjustment screw 85 for adjusting the fouling amount of the first elastic lock teeth 81 in the rod direction to adjust the first elasticity by adjusting the screw 85. The latching amount of the lock teeth 81 in the rod direction is to achieve a lock or backward direction of the first elastic lock teeth 81 and the lock teeth inward.

[0042] When the rotation adjustment screw 85 causes the first slider 831 to hold the first elastic lock teeth 81 compress the third spring 84, the first elastic lock teeth 81 shrinks to cause the rack 4 to drive the lock groove 43 during the sliding process. When the limit...

Abstract

The invention discloses a rubber tapping knife for a rubber tapping machine. The rubber tapping knife is provided with a worm and a rack, so that the worm rotates to drive the rack to perform telescopic motion, the knife is pushed to perform telescopic motion to realize knife discharge and knife collection, the elongation of the knife is controlled by virtue of elastic teeth, so that the rubber tapping knife adapts to rubber tapping of rubber trees with different diameters, and the applicability of the rubber tapping knife is effectively improved. Meanwhile, a plurality of elastic locking teeth are arranged, so that locking grooves in the rack sliding to the elastic locking teeth are locked, the precision of spiral feeding rubber tapping of the knife is effectively improved, and the problem that the rubber tapping depth of the knife is not uniform is solved. Besides, by arranging a rotary unlocking device and a ratchet wheel, the ratchet wheel pushes the rotary unlocking device to drive the elastic lock teeth to slide out of the lock grooves to unlock the rack in the knife retracting process, and therefore, the knife can retract into a limiting sliding way to be retracted.

Description

Technical field [0001] The present invention relates to the field of rubber cutting techniques, and in particular a splitter for a splitter. Background technique [0002] Natural rubber is obtained from the latex when the rubber tree cut glue is solidified, and after drying. Rubber is the basic raw material of the rubber industry, which is widely used in manufacturing tires, hose, tape, cable and other various rubber products. The rubber tree will secrete a large amount of a rubber emulsion of a tree liquid in a hurt (such as bark being cut); the rubber tree needs to be used in the process of cutting the rubber, and the cutting knife is spirally rotated around the rubber tree on the spiral track. Rubber bark is cut. The prior art case mainly includes a tool and a driving device that controls the tool extended and retracted. The drive is rotating onto the rubber bark, since the driving device also controls the helical movement of the tool, spiral rotation of the knife During the c...
