DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] A bamboo chip slitting device comprises a mounting frame 1, a slitting mechanism 2 mounted on the mounting frame 1 and a feeding mechanism (not shown in the figure, and can be composed of a feeding transmission and other prior art) for feeding materials to the mounting frame 1.

[0036] like Figure 1 and Figure 2 As shown, the mounting frame 1 includes two mounting rings in the form of open rings (support frames are connected at the open ends to support the overall mounting rings), and a mounting channel is formed between the two mounting rings, and convex strips 11 are provided on the two side walls of the mounting channel, and a plurality of evenly distributed limiting grooves are provided on the outer peripheral edges of the two mounting rings.

[0037] like Figure 4As shown, the slitting mechanism 2 includes a knife seat 21 and a limit seat 22 that can slide into the installation channel, and the two side walls of the knife seat 21 and the limit seat 22 are provided with grooves 23 that cooperate with the convex strip 11 (conversely, a convex rod can be provided on the limit seat 22 and a groove can be provided on the inner wall of the installation channel), the knife seat 21 is connected to a slitting knife 24 extending toward the center of the open ring, and the limit seat 22 is connected to a limit rod 25 that can be inserted into the limit groove.

[0038] For further reference, Figure 6 As shown, a driving rod 5 is rotatably mounted on the tool seat 21, and an adjusting screw 4 is rotatably mounted inside the tool seat 21. The driving rod 5 is perpendicular to the adjusting screw 4, and a transmission bevel gear set is connected between the driving rod 5 and the adjusting screw 4. In addition, the adjusting screw 4 is screwed through the limit seat 22.

[0039] Further, refer to Figure 7 and Figure 8 As shown, the limit seat 22 is provided with a mounting groove, and a movable mounting column 27 is provided in the mounting groove, and the limit rod 25 is fixed on the mounting column 27. Specifically, the mounting column 27 includes an inner column 271, and a limit screw rod 28 is also rotatably installed in the mounting groove, and the limit screw rod 28 is screwed through the inner column 271.

[0040] From the above, we can see that when cutting bamboo strips:

[0041] According to the specifications of the bamboo pieces to be cut, a suitable number of cutting mechanisms 2 are installed on the mounting frame 1: Figure 1 As shown, the knife seat 21 and the limit seat 22 of the slitting mechanism 2 are slid into the installation channel from the opening of the open ring, and it is ensured that the convex strip 11 is engaged with the groove 23. Move the knife seat 21 and the limit seat 22 to the specified position in the installation channel (to ensure that multiple slitting mechanisms 2 are evenly distributed), fix the knife seat 21 by hand to maintain the current position, and drive the adjusting screw 4 to rotate by rotating the drive rod 5, thereby driving the limit seat 22 to move, so as to adjust the position of the limit seat 22 and the limit rod 25, and ensure that the limit rod 25 corresponds to the limit groove. Rotate the limit screw 28 to drive the installation column 27 to move in the installation groove, so that the limit rod 25 is stuck in the corresponding limit groove. In summary, the limit installation of the slitting mechanism 2 is completed.

[0042] After the installation is completed, the feeding mechanism is used to realize the automatic feeding of the bamboo to be cut, and the bamboo is cut into bamboo pieces by the cutting knife 24 during the feeding process. Figure 1 Taking the eight cutting mechanisms 2 shown as an example, eight bamboo slices can be formed by cutting.

[0043] On the basis of the above, continue to refer to Figure 7It can be seen that the mounting column 27 and the limiting rod 25 are both provided with two groups, and each of the limiting screw rods 28 is fixedly sleeved with a driven gear 281, and a driving gear 29 is rotatably installed on the limiting seat 22, and the driven gear 281 is meshed and connected with the driving gear 29, thereby realizing the synchronous driving of multiple limiting screw rods 28 by rotating the driving gear 29. In addition, when two or more groups of limiting rods 25 are provided, since the limiting groove is provided on the outer peripheral edge of the mounting ring, only using the limiting screw rod 28 to drive the inner column 271 to move will cause some limiting rods 25 to be unable to be completely inserted into the limiting groove. Based on this, it is preferred that the mounting column 27 further includes an outer sliding sleeve 272, which is slidably sleeved on the outside of the limiting screw rod 28 and the inner column 271, and a spring 273 is connected between the outer sliding sleeve 272 and the inner column 271, and the limiting rod 25 is fixed on the outer sliding sleeve 272.

[0044] On the basis of the above, continue to refer to Figure 2 and Figure 3 It can be seen that the slitting knife 24 is in a U-shaped structure, and the slitting knife 24 slides through the knife seat 21. A threaded sleeve 26 (such as Figure 6 As shown, the threaded sleeve 26 is coaxially sleeved on the outside of the driving rod 5), the threaded sleeve 26 is located in the U-shaped groove of the slitting knife 24, and the threaded sleeve 26 is screwed and connected with the slitting knife 24. Based on this, the slitting knife 24 can be driven to move along the radial direction of the open ring by rotating the threaded sleeve 26, thereby changing the length of the slitting knife 24 inside the open ring, that is, ensuring that the slitting mechanism 2 can be installed in the open ring-shaped installation channels of different diameters.

[0045] On the basis of the above, continue to refer to Figure 2 , Figure 5 and Fig. 9 It can be known that a guide frame 3 is slidably installed in the U-shaped groove of the slitting knife 24, and a threaded column 31 and a guide roller 32 are rotatably installed on the guide frame 3. The threaded column 31 is located in the U-shaped groove of the slitting knife 24 and is screwed together with the slitting knife 24. The guide roller 32 is located on one side of the mounting frame 1. Based on this, the guide frame 3 can be driven to slide in the U-shaped groove of the slitting knife 24 by rotating the threaded column 31, thereby changing the position of the guide frame 3 and the guide roller 32 to ensure that the guide roller 32 can contact the surface of the bamboo to be slit, thereby effectively realizing the feed guide limit, and can also be flexibly applicable to the feeding of bamboos of different diameters. Regarding the rotation of the guide roller 32, the guide roller 32 can be driven to rotate passively by the feeding movement of the bamboo, or a motor, a power supply battery and other structures can be installed on the guide frame 3 to realize the active rotation of the guide roller 32.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
