Method and device for turning over bamboo chips used for summer sleeping mat

Abstract

The invention discloses a method and device for turning over bamboo chips so as to ensure that green surface or yellow surface of each bamboo chip faces towards the same direction absolutely. The method and the device are characterized in that decoration and drilled or knitted bamboo chips are placed in a container filled with liquid; the liquid is in a stationary or flowing state; the specific gravity of the liquid is larger than that of bamboo chips; the bamboo chips are raised to the surface of the liquid under the effect of buoyant force; the specific gravities of the green surface and the yellow surface of the bamboo chip are different, and the bamboo is turned over in the raising process, so that the yellow surface of the bamboo chip floating on the surface of the liquid faces upwards, and the green surface faces downwards. The method is unique and simple, easy to implement, low in cost and high in efficiency, and the same orientation of green surface or yellow surface of each bamboo chip can be ensured absolutely so as to facilitate decoration and drilling of bamboo chip and mechanical knitting of mahjong summer sleeping mats.

Description

technical field [0001] The invention relates to the processing of a bamboo mat, in particular to a method and a device for turning over bamboo chips for a mat, in particular to a method and a device for turning over finished bamboo chips for a mat. Background technique [0002] The processing and production of bamboo mats generally includes the following steps: sawing off the original bamboo, cutting it into bamboo strips of specified width, and then sawing them into bamboo slices according to the specified length; arranging flowers and drilling holes on the bamboo slices; Processing: Weave bamboo slices and beef tendons into mats according to the size of specifications. [0003] In the flower arrangement and drilling steps of the bamboo slices, in order to ensure that the green surface of the bamboo slices is not worn or damaged during the flower arrangement, the green surface will not be damaged, and the bamboo slices will not be rotten when drilling. During processing, t...

Problems solved by technology

However, there are also problems such as whether the detection is accurate

[0008] Because of the bamboo chips after surface treatment including anti-insect, polishing, etc., the green surface has a smaller curvature and a smaller color difference (carbonized bamboo chips are smaller), therefore, the above detection methods for bamboo chips cannot be applied.

At the same time, if it is not possible to guarantee 100% that the green or yellow faces of each bamboo slice are in the same direction, it will be impossible to realize the mat by mechanical weaving.
