Description

Technical Field

[0001] The invention belongs to the technical field of bamboo material processing, and in particular relates to a chord-wise bamboo chip unit continuous processing device and a bamboo chip unit. Background Art

[0002] With the prevalence of low-carbon concepts and the concept of "bamboo is better than wood", the research on high-quality bamboo products has gradually become more popular. Compared with wood, bamboo has the characteristics of high strength, good toughness, high strength, and beautiful texture. It is an ideal raw material for engineering structures and decorative materials. However, the characteristics of bamboo such as small diameter, hollowness, and thin walls restrict its industrial development. The currently developed bamboo units have problems such as low bamboo utilization, bamboo units destroying the original bamboo structure, and unstable paving structures. Due to the different structures of bamboo and wood, it is difficult to effectively use the existing mature wood processing machinery in bamboo processing. The development of bamboo has only been around for more than 40 years since the 1980s. Bamboo processing machinery is mainly based on independent research and development. At present, bamboo processing is basically staged mechanized processing, lacking continuous production technology and equipment.

[0003] The upgrade of the basic unit of bamboo will bring innovation in the development of bamboo materials. From fine planed bamboo strips, bamboo flattened, bamboo pieces, bamboo shavings, bamboo fibers to bamboo fiber bundles, it records the typical development process of bamboo materials from ordinary bamboo flooring, bamboo flattened, bamboo plywood, bamboo particleboard, bamboo fiberboard to bamboo recombinant materials. Bamboo pieces are high-quality bamboo units. Due to the relatively weak processing machinery and unstable unit performance, they are mainly used for weaving bamboo curtains and bamboo mats and then pressing boards, and the board quality is not high.

[0004] At present, the preparation process of bamboo chips mainly adopts traditional bamboo splitting machines. The bamboo chip units and processing machinery are relatively simple, the processing efficiency is low and the bamboo material utilization rate is low. The unit preparation technology needs to be upgraded. Summary of the invention

[0049] The continuous planing device is used to continuously rotate and plan the bamboo tube after the outer bamboo nodes are removed;

[0050] The bamboo tube fixing device for removing outer bamboo nodes comprises two clamping fixtures, which are respectively defined as clamping fixture A (such as Figure 1 The clamping fixture shown on the left) and the clamping fixture B (as shown Figure 1 The two clamping fixtures are arranged opposite to each other, one of which is mounted on an inverted U-shaped frame 111, which is mounted on a workbench A and is located directly above the transmission device, and the other clamping fixture is mounted on a lifting frame 112. The lifting frame can adopt an existing publicly available frame structure for realizing lifting, such as a cylinder, an electric lifting rod, etc. This type of structure is a conventional structure in machinery and will not be described in detail here.

After the opening device opens the first connecting rod 108 and the second connecting rod 109, the stopper 110 presses against the inner wall of the bamboo tube to be processed, thereby clamping and fixing the bamboo tube to be processed;

[0053] The number of the first connecting rods 108 and the number of the second connecting rods 109 are both four, which are evenly distributed around the circumference of the rotating shaft 5 .

[0054] The resisting member 110 is a square structure, and the number of the resisting members 110 is also 4. The weight of the two resisting members 110 located at the top is lighter than the weight of the two resisting members 110 located at the bottom.

The cylindrical mounting seat 121 is also mounted with washers 122 located on both sides of the tool mounting sleeve, and the washers 122 can reduce the wear of the tool mounting sleeve and reduce friction. A third spring 124 is mounted on the telescopic rod of the second cylinder 113, and both ends of the third spring 124 are fixed between the cylinder body of the second cylinder 113 and the U-shaped seat 120;

[0058] In this embodiment, the second cylinder 113 can be a single-rod cylinder or a double-rod cylinder, preferably a double-rod cylinder; the two telescopic rods of the double-rod cylinder are respectively connected to two U-shaped seats 120, and the two U-shaped seats 120 are connected to an outer bamboo joint removal tool 115 through a tool mounting sleeve of a cylindrical mounting seat 121. By using two U-shaped seats 120 to connect an outer bamboo joint removal tool 115, the tool can be set wider, and the connection position is tighter and less likely to be damaged.

[0059] The outer bamboo node removal mechanism also includes a straightening device, which includes a horizontally arranged fourth cylinder 125, the bottom of which is installed on a height adjustment device, which is a third cylinder 126, and a straightening roller 127 is fixedly installed on the telescopic rod of the fourth cylinder 125; the fourth cylinder 125 is controlled to press the outer wall of the straightening roller 127 against the inner wall of the cylindrical outer bamboo node removal tool 115, and the third cylinder 126 is controlled to make the fourth cylinder 125 rise and fall, that is, the straightening roller 127 straightens the shape of the outer bamboo node removal tool 115 from a cylindrical shape to a parallelogram during the lifting and lowering process.

[0060] The side of the outer bamboo node removal tool 115 that contacts the bamboo green is set to be a rough surface, which can perform preliminary roughening on the bamboo green surface while removing the bamboo green. The roughened structure is similar to the surface structure of a file, with many protrusions distributed in a matrix.

[0074] Except for the horizontal slide at the top, the starting ends of the other horizontal slides are all provided with lifting touch switches 14, and the lifting touch switches 14 of each horizontal slide control the fifth cylinder group 15 of the lifting device connected to the oblique slide connected to the starting end of each horizontal slide. The fifth cylinder group 15 includes two fifth cylinders, which are fixedly installed on the workbench B.

[0075] The working process of continuously planing the bamboo tube 2 to be processed after the outer bamboo nodes have been removed:

[0076] The bamboo tube 2 to be processed with the outer bamboo nodes removed is placed on the horizontal slide of the uppermost layer, and the bamboo tube fixing device to be processed located on the stepped work surface on the left side of the layer clamps and fixes one end of the bamboo tube 2 to be processed with the outer bamboo nodes removed, and the other end of the bamboo tube 2 to be processed is pressed against the planing blade 5 inside the circular mounting shell 20 of the planing device of the layer. After the bamboo tube 2 to be processed is fixed, the rotating cylinder 103 on the bamboo tube fixing device to be processed controls the rotation of the bamboo tube, and the first cylinder 101 is placed on the bamboo tube fixing device to be processed to continue to extend, and the planing blade 5 realizes the rotation planing of the bamboo tube 2 to be processed until the uppermost layer After the planing device completes one planing, the bamboo tube 2 to be processed falls on the uppermost inclined slide, and the bamboo tube 2 to be processed slides into and touches the lifting touch switch 14 on the second-layer horizontal slide, and the lifting device controlling the lifting on the uppermost inclined slide begins to descend until the inclined direction of the uppermost inclined slide becomes horizontal. After the bamboo tube fixing device to be processed corresponding to the second-layer horizontal slide works to clamp and fix the bamboo tube 2 to be processed, it is rotated and pushed into the planing device corresponding to the second-layer horizontal slide for secondary planing, and then the above operation is continued to realize continuous, layer-by-layer, and rotary planing of the bamboo tube 2 to be processed.

[0077] The above is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent change made to the above embodiment according to the technical essence of the invention still falls within the protection scope of the technical solution of the present invention.
