Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bamboo and wood material processing, and particularly relates to a cantilever type jump cutter mechanism and bamboo and wood material processing equipment. Background Art
[0002] There are many types of bamboo and wood, and common ones include Moso bamboo, Indocalamus tessellatus, Setaria sphacelata, etc. Bamboo is a fast-growing plant with a short growth cycle and strong renewable ability, so it has high sustainability. The fibers of bamboo are flexible and uniform, with high strength and toughness, and are more pressure-resistant, wear-resistant and shock-resistant than other woods, so they are widely used in furniture and construction fields.
[0003] A bamboo and wood cutting machine disclosed in Patent CN114131699B includes a frame, a cutting mechanism arranged on the frame, clamping mechanisms arranged on both sides of the cutting mechanism, and a pushing mechanism arranged at one end of the cutting mechanism; the cutting mechanism includes a support column, a guide column arranged at a relatively spaced position with respect to the support column, a connecting plate connecting the support column and the guide column, a cutting assembly arranged on the connecting plate, and an internal cutting assembly arranged on the support column, and the internal cutting assembly is arranged opposite to the pushing mechanism. Compared with the related art, the bamboo and wood cutting machine provided by the present invention has high automation degree, improves production efficiency and is beneficial to safe production.
[0004] In the above solution, there are clamping mechanisms and a pushing mechanism for fixing and feeding, and a guide column is also provided to maintain the relative position of the bamboo and wood with the cutting mechanism. The cutting of bamboo and wood materials all proceeds along the guide rail. However, the shapes of bamboo and wood materials are various, especially the thickness of the materials will change with different positions of the bamboo. The fixed cutting trajectory only cuts at the set thickness. Although materials with uniform thickness are cut out, too much of the excess part is cut off, which will cause waste of materials, not only increase the production cost, but also indirectly increase the damage to the environment.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] The following are specific embodiments of the utility model and in combination with the drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.
[0025] Embodiment 1
[0026] As Figures 1 - 3 shown, a cantilever type jump cutter mechanism includes a material supporting fixing plate 2 fixed on the frame 1, the frame 1 is hinged with a cantilever frame 3 and the cantilever frame 3 has a free end, an elastic support member 4 is arranged on the frame 1 to support the free end of the cantilever frame 3 from bottom to top, a cutting tool 5 is arranged on the cantilever frame 3 above the material supporting fixing plate 2, and an adaptive material passing gap is left between the cutting tool 5 and the material supporting fixing plate 2 under the support of the elastic support member 4, and the cutting tool 5 is connected with the rotary driving device 6.
[0027] That is, a cantilever 3 with a cutting tool 5 is hingedly mounted on the frame 1, enabling the cutting tool 5 to adjust its height up and down by relying on the cantilever 3 to adapt to different thicknesses of the material, allowing the cutting tool 5 to only shave off the outer skin on the surface of the bamboo and wood, ensuring that as much of the usable part of the bamboo and wood is retained as possible, and improving the utilization rate of the material. The cantilever 3 is supported by an elastic support member 4, and the force difference between the two just enables the cutting tool 5 to maintain a fixed distance from the material support fixing plate 2 and can undulate along with the surface of the material when contacting the material, playing a role of self-adaptive adjustment. The elastic support member 4 also plays a role in offsetting the self-weight on the cantilever side, so that the cutting tool 5 can perform machining such as planing and milling.
[0028] In this embodiment, the cantilever 3 includes a lower cantilever 31 and an upper cantilever 32 located above the lower cantilever 31. One end of the lower cantilever 31 is hinged to the frame 1, and the other end of the lower cantilever 31 is free. One end of the upper cantilever 32 is hinged to the frame 1, and the other end of the upper cantilever 32 is free. The other ends of the lower cantilever 31 and the upper cantilever 32 are respectively connected to a pull rod 33 through hinges.
[0029] The lower cantilever 31, the upper cantilever 32, and the pull rod 33 form a hinged parallelogram, where two adjacent corners are hinged to the frame 1, enabling the lower cantilever 31 and the upper cantilever 32 to swing up and down synchronously, and the elastic support member 4 is connected to the upper cantilever 32 to maintain the stability of the parallelogram.
[0030] In this embodiment, the rotary drive device 6 includes a tool motor 61 fixed to the lower cantilever 31. The cutting tool 5 is fixed to a rotary main shaft 62, and the rotary main shaft 62 is rotatably connected to the upper cantilever 32. The tool motor 61 is connected to the rotary main shaft 62 through a belt drive structure.
[0031] The rotary main shaft 62 is arranged at the swinging end of the upper cantilever 32, and the tool motor 61 is also arranged on the lower cantilever 31 at a position equidistant from the hinged end as the upper cantilever 32, so that the output end of the tool motor 61 and the rotary main shaft 62 can maintain an unchanged distance regardless of how they swing, ensuring that the way they are driven by the belt will not be affected by the swing and maintaining the uninterrupted output of power.
[0032] In this embodiment, an arch-shaped frame 63 sleeved outside the tool motor 61 is provided on the lower cantilever 31, and the lower end of the pull rod 33 is hinged to the top of the arch-shaped frame 63.
[0033] The distance between the hinge point of the arch-shaped frame 63 and the lower cantilever 31 plus the length of the pull rod 33 is equal to the distance between the two hinge points of the lower cantilever 31 and the upper cantilever 32 and the frame 1.
[0034] In this embodiment, the pull rod 33 is a pull rod with an adjustable telescopic length.
[0035] Because the lower cantilever 31 and the upper cantilever 32 can be disassembled and used on other racks 1, and the distance between the two hinge points of the two racks 1 will also change, the tie rod 33 is adjustable in length.
[0036] Among them, the tie rod 33 includes a screw part and a sleeve rod part. The screw is inserted into the sleeve rod. An internally threaded ring that can rotate circumferentially is arranged at the socket end of the sleeve rod to cooperate with the screw. By rotating the internally threaded ring at the end of the sleeve rod, the position of the screw extending into the socket is adjusted, so as to change the actual length of the tie rod 33.
[0037] In this embodiment, the elastic support 4 includes a fixed rod 41 in an upright state. A spring 42 is sleeved on the fixed rod 41. A shoulder 43 placed on the upper end of the spring 42 is arranged on the cantilever frame 3. A nut group is also threadedly connected to the fixed rod 41, and the nut group abuts against the top surface of the shoulder 43.
[0038] The lower end of the fixed rod 41 is set on the rack 1. The spring 42 is fixedly sleeved on the fixed rod 41. The upper end of the fixed rod 41 passes through the through hole opened on the shoulder 43. The sleeved spring 42 is larger than the through hole and abuts against the lower end of the shoulder 43. The part passing through the through hole is threadedly matched with the nut group. By tightening the nut group, the shoulder 43 is compressed downward against the spring 42, so that the cutting tool 5 on the cantilever frame 3 is closer to the stock support fixing plate 2, or by loosening the nut group, the spring 42 pushes the shoulder 43 to a higher position, so that the cutting tool 5 on the cantilever frame 3 is farther away from the stock support fixing plate 2.
[0039] Preferably, the nut group includes a lower nut 44 and an upper nut 45. A spacer sleeve 46 is arranged between the lower nut 44 and the upper nut 45.
[0040] The upper nut 45 and the lower nut 44 are set as double nuts for strengthening fixation, and a spacer sleeve 46 is arranged between the two nuts to prevent the two nuts from contacting and interfering with each other.
[0041] Preferably, the lower end of the spring 42 acts on the top of the lower limit nut 47.
[0042] A lower limit nut 47 is also threadedly matched on the fixed rod 41 on the lower side of the spring 42. The upper end of the lower limit nut 47 has an annular limit platform. The limit platform abuts against the lower end of the spring 42 and cooperates with the upper nut group to compress the spring 42 together.
[0043] Among them, the lower limit nut 47 can adjust its height position on the fixed rod 41 by rotation. In addition, the nut group can be removed from the upper side, which facilitates the replacement of the spring 42 on the fixed rod 41, and can adapt to springs 42 of different lengths by adjustment.
[0044] Embodiment 2
[0045] As Figure 1As shown in the figure, the cantilever type jump cutter mechanism in Embodiment 1 is applied to the bamboo and wood material processing equipment. A plurality of sets of feeding wheel groups 7 are spaced apart and arranged on the frame 1, and a material supporting fixed plate 2 is arranged between two of the feeding wheel groups 7.
[0046] The feeding wheel group 7 includes an upper feeding wheel and a lower feeding wheel which are symmetrically arranged up and down. The lower feeding wheel is fixedly installed on the frame 1 and ensures that the upper wheel surface of the feeding wheel is flush with or slightly higher than the material supporting fixed plate 2. The upper feeding wheel is arranged on the upper side through a spring, so that the upper feeding wheel abuts against the vertex of the lower feeding wheel by using the elastic force, and the pressure between the upper and lower wheels generates a power sufficient to drive the material forward.
[0047] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
