Embodiment 1

[0031] like Figure 1 to Figure 7 As shown, the present invention provides a rubber tapping knife for a rubber tapping machine, comprising a frame 1 that can move on a spiral track 14, the lower part of the frame 1 is connected to a limit slide 2; the limit slide 2 is provided with a rotatable The worm 3 and the slidable rack 4, the end of the rack 4 is provided with a cutter 11; the rack 4 is provided with a number of retractable elastic teeth 5 for adjusting the extension of the cutter 11. There are also a number of fixed teeth 6 for pushing the cutter 11 forward and backward, and the elastic teeth 5 and the fixed teeth 6 are connected with the worm 3 in a drive, so as to make the worm 3 rotate through the drive connection between the worm 3 and the rack 4 Drive the rack 4 to move forward and backward in a straight line, thereby driving the rubber tapping tool 11 to take out and retract; the limit slide 2 is provided with a rotary unlocking device 7 for unlocking the rack 4 ...

Embodiment 2

[0036] like Figure 1 to Figure 7 As shown, combined with the technical solution of Embodiment 1, in this embodiment, spring grooves 21 are provided on both sides of the limit slideway 2, the first spring 12 is provided in the spring groove 21, and the ends of the rack 4 are provided on both sides. There is a protrusion 42 that slides against the first spring 12, so that the first spring 12 can reverse the sliding out of the rack 4, so that when the elastic teeth 5 retract into the rack 4, the rack 4. Rebound under the force of the first spring 12 to make the teeth abut on the worm 3 quickly, so as to realize the rapid retraction of the cutter 11. For the rubber tapping method when the cutter returns to the bottom, that is, the cutter 11 starts from the bottom. The top method of spiral cutting around the tree and then wrapping and returning to the position, and the rapid closing of the knife can avoid the returning cutting of the bark by the knife 11.

Embodiment 3

[0041] like Figure 5 and Figure 7 As shown, combined with the technical solution of Embodiment 2, in this embodiment, the sliding rod 83 includes a first sliding rod 831 and a second sliding rod 832, the first sliding rod 831 is connected with the first elastic locking teeth 81, and the second sliding rod 832 is connected with the second elastic locking tooth 82; the first sliding rod 831 is threadedly connected with an adjusting solenoid 85 for adjusting the expansion and contraction amount of the first elastic locking tooth 81 along the rod direction, so as to adjust the first elasticity through the adjusting solenoid 85 The expansion and contraction amount of the locking teeth 81 along the rod direction is used to realize the locking of the first elastic locking teeth 81 and the locking teeth in both forward and backward directions or locking in the backward direction.

[0042] When the adjusting solenoid 85 is rotated to cause the first sliding rod 831 to stretch the fi...

Abstract

The invention discloses a rubber tapping knife used for a rubber tapping machine. By arranging a worm and a rack, the worm rotates to drive the rack to perform telescopic motion, thereby pushing the knife to telescopically move to, so as to realize the cutting and closing of the knife. And rely on elastic teeth to control the elongation of the tool to adapt to the rubber tapping of rubber trees of different diameters, and effectively improve the applicability of the rubber tapping knife. At the same time, by setting a number of elastic locking teeth, the lock grooves on the rack sliding to the elastic locking teeth can be locked, which can effectively improve the precision of the tool's spiral cutting and rubber tapping, thereby reducing the uneven depth of the tool's rubber tapping. . In addition, the rotating unlocking device and the ratchet are provided to realize the process of the tool retracting the knife. The ratchet pushes the rotating unlocking device to drive the elastic locking teeth to slide out of the lock groove to unlock the rack, so that the tool can be retracted into the limit slideway. Close the knife.

Description

technical field [0001] The invention relates to the technical field of rubber cutting, in particular to a rubber tapping knife for a rubber tapping machine. Background technique [0002] Natural rubber is obtained by coagulating and drying the latex that flows out of rubber trees when tapping. Rubber is the basic raw material of the rubber industry and is widely used in the manufacture of tires, hoses, tapes, cables and other various rubber products. When the rubber tree is injured (such as the bark is cut), it will secrete a large amount of sap containing rubber emulsion; the rubber tree needs to use a rubber tapping knife in the process of rubber tapping. The rubber bark is cut. The prior art rubber tapping knife mainly includes a cutter and a driving device that controls the extension and retraction of the cutter. The driving device rotates and pushes the cutter to extend against the rubber tree bark. Since the driving device also controls the helical motion of the cutt...
