Processing method and boring and fine grinding device for bamboo chips for piece-to-piece jointed mat and application thereof

Abstract

The invention discloses an environment-friendly and pollution-free processing method for bamboo chips for a piece-to-piece jointed mat. The method is characterized by comprising the following steps: (1) cutting a bamboo tube into bamboo chips; (2) performing boring and fine grinding on the bamboo chips on a boring and fine grinding device; (3) roasting; (4) washing with water; and (5) drying. The boring and fine grinding device comprises a frame which comprises thereon a longitudinal feeding mechanism for feeding in a bamboo chip length direction, a feeding track, a side face abrading and grinding mechanism, an auxiliary hole boring mechanism, a green surface grinding mechanism, a transverse feeding mechanism in a bamboo chip width direction, a feeding disc, and a bamboo chip end face boring and grinding mechanism. The method and the device are applicable to abrading of both side faces of the bamboo chips in the length direction, boring in the length direction, and grinding and polishing of the green surfaces and four side faces in the length and width directions of the bamboo chips. The method disclosed by the invention is feasible; the obtained products can be directly fed to the roasting step, thereby avoiding pollution caused by bamboo chip sanding and water washing steps to the environment; the device is simple in structure, convenient to maintain, low in operating cost, and easy to operate and control, and full-automatic intelligent control can be achieved.

Description

technical field [0001] The present invention relates to the production of a mahjong mat, in particular to a processing method for mahjong mat bamboo chips, a drilling and fine grinding device and its application, in particular to an environmentally friendly and pollution-free processing of mahjong mat bamboo chips A method and a drilling fine grinding device and applications. Background technique [0002] In the scorching summer, the mahjong mat made of bamboo slices has become a must-have "magic weapon" for citizens to enjoy the cool air. The processing method of existing mahjong mats with bamboo chips generally includes the following steps: remove the head and tail of the newly felled moso bamboo and process them into fixed-length bamboo tubes, then machine the bamboo tubes into bamboo strips with the same width and thickness, The bamboo strips are sawed into bamboo blanks of a set length; then, lace (commonly known as flower arrangement) is processed in the length direct...

AI Technical Summary

Problems solved by technology

In the steps of sand grinding and water washing, since the sand and bamboo chips cannot be separated, the sand cannot be reused and can only be discharged directly, causing soil compaction and polluting the environment, and the sewage after washing has a great impact on the environment. Therefore, the production of mahjong mats It is designated as a high-energy-consumption and heavy-pollution industry by the government department, and is subject to great constraints

Moreover, in the boiling and dyeing step, it is neither environmentally friendly, but also leaves harmful substances to the human body, causing people to be infected with various skin and respiratory diseases.
