Description

Bamboo OSB flaker

technical field

The utility model belongs to a bamboo flaking machine, in particular to a flaking machine specially used for producing bamboo OSB shavings.

Background technique

my country is the world's largest bamboo resource country. Bamboo has the characteristics of rapid growth, short rotation period, hollow and knotted, and strong shear resistance. Processing bamboo into OSB (oriented strand board) not only makes full use of the strong physical and mechanical properties of bamboo, but also can replace bamboo in many uses. Timber can effectively alleviate the contradiction between the supply and demand of timber in my country. The main technical difficulty in manufacturing bamboo OSB is to produce bamboo shavings that meet the requirements. There are many devices for wood and bamboo chipping at present, but there are many deficiencies in making bamboo OSB shavings, for example:

1. Drum chipper

The drum chipper uses the flying knife installed on the knife drum to cut from the end face. This machine is mainly used for wood cutting to obtain relatively rough wood chips. Due to the special physiological structure of bamboo, it is impossible to cut bamboo with a drum chipper, and it is impossible to obtain flakes of bamboo shavings, which cannot meet the requirements of shavings for bamboo OSB production.

2. Disk chipper

The disc chipper mainly uses the flying knife installed on the cutter head to cut wood chips or bamboo chips into shavings. The main disadvantage of making bamboo OSB shavings is that it cannot form shavings into pieces. Using this equipment to slice bamboo will basically get toothpick-like shavings, and it cannot be oriented, so that large areas of bamboo green and bamboo yellow remain on the same piece of shavings. , affect gluing, and cannot meet the shaving requirements of bamboo OSB production.

3. Long material planer

Long wood flakers are mainly used for cutting large-diameter wood. When cutting wood, they can form better shavings. However, long wood flakers cannot complete directional cutting of bamboo, leaving a large area of bamboo green and bamboo yellow in the same area. The gluing side of a piece of wood shavings, affecting gluing. Simultaneously the design of cutter ring is also unfavorable for the formation of large bamboo wood shavings, can't satisfy the shaving requirement of bamboo wood OSB production.

After the feeding is completed, the upper heavy pressure device 2 on the transition frame 3, the side pressure device 7 and the indoor floating weight 10 in the cutting chamber 4 are simultaneously pressurized to the set pressure value to clamp the bamboo and prepare for cutting.

After the bamboo enters the cutting chamber 4, the cutting chamber 4 and the high-speed rotating knife ring 5 driven by the main transmission system 9 start to advance perpendicular to the length direction of the bamboo under the action of oil pressure, and the bamboo is cut, so that the cutting is pushed and supported. The bamboo used in the process ensures the cutting continuity of the knife ring. Because the cutting edge of cutting knife 52 is higher than the edge of cutting knife 51, the dividing knife 52 on the knife ring contacts cutting surface at first, cuts out the transverse scratch of certain depth earlier on bamboo chip, and cutting knife 51 touches cutting surface subsequently, will Bamboo is cut into lengths of shavings. During the splitting process, the scratches should not be too deep, to prevent the bamboo from breaking in advance and make it difficult to orientate; nor should it be too shallow, to prevent the bamboo from being torn in advance and unable to form complete shavings. The height of the cutting knife above the bottom knife bed of the knife door is the thickness of the cutting chip. In this embodiment, the blade height of the dividing knife above the bottom knife bed of the knife door is more than 2 times and less than 3 times the height of the cutting knife above the knife bed of the knife door bottom knife bed, and the knife ring between the two dividing knives Two cutting knives are arranged on the top, that is, the ratio of the number of dividing knives to the number of cutting knives is 2:1. First, the splitting knife scratches the bamboo with a depth of twice the thickness of the shavings, and then the two cutting knives plan the scratched bamboo. For specific applications, by adopting combinations of cutting knives 51 and dividing knives 52 in different numbers and ratios, and using the adjustment device on the side wall of the knife holder to properly adjust the cutting depth of each knife, the thickness of the shavings can be adjusted, and the dividing and dividing The depth of the mark is adjusted to several times the thickness of the shavings. A discharge belt 8 is provided below the cutting chamber, which transports the shavings falling naturally from the cutting chamber 4 to the shavings silo.

When the sliding seat 6 moves forward to complete a stroke, the cutter ring 5 is still running dry after cutting, the oil circuit of the hydraulic system is switched, and the sliding seat 6 quickly returns to the position ready for cutting under the action of the hydraulic cylinder; The heavy pressure device 2, the side pressure device 7 and the indoor floating weight 10 in the cutting chamber 4 are decompressed, but they are still in contact with the bamboo chips. If the detection device detects that there is no raw material in the range of the transition frame, the two oil cylinders will retract to the original state. state, so that the conveyor feeds; then the plate chain conveyor 1 feeds again, and restarts the cutting of the next cycle, so reciprocating.

The shavings produced by this flaking machine, bamboo green a2 and bamboo yellow a1 are respectively distributed on the narrow surfaces of both sides of the bamboo shavings, as shown in Figure 8.
