Description

Preparation process of high-quality super-strong shaving board

Technical Field

The invention belongs to the field of building material home furnishing, and particularly relates to a preparation process of a high-quality super-strong shaving board.

Background

In recent years, the customized furniture industry in China is developed vigorously, and the rapid development of the upstream artificial board industry of the customized furniture is driven. The shaving board has the advantages of good mechanical property, dimensional stability, easy processing and facing and the like, so the shaving board is widely applied to the production of customized furniture. With the increase in the pursuit of consumers for home space design and utilization, custom furniture cabinet designs sometimes need to be widened or heightened according to the requirements of indoor space design. However, in the design of the traditional customized furniture, because the static bending strength of the shaving board is not high, the bending resistance of the board after bearing pressure is obviously reduced when the internal span of the cabinet is large, and hardware or a reinforcing piece is required to be used for assisting in improving the bearing capacity of the cabinet. How to improve the static bending strength of the shaving board, break through the limitation of the board to the design of the customized furniture, and is a problem to be solved urgently in the current furniture market.

The high-strength shaving board is called as super-strength shaving board by the industry, along with the continuous improvement of the cognition of consumers, the requirements on products and living environment are stricter and stricter, the existing product quality in the market can not meet the more and more individual and special requirements of the consumer market, and the market lacks the breakthrough of the related process of the super-strength shaving board, so that new vitality is injected for the development and the promotion of the shaving board industry.

Disclosure of Invention

The invention aims to provide a preparation process of a high-quality super-strong shaving board so as to respond to the problems involved in the background technology.

The purpose of the invention can be realized by the following technical scheme: a preparation process of a high-quality super-strong shaving board mainly comprises the following implementation steps: the method is characterized in that a special chipping machine and a flaking machine are selected to prepare raw material flake shaving pieces, a single-channel dryer is selected to dry shavings with different sizes, and the final moisture content of the dried shavings is guaranteed to be about 2%. The wood shavings screening uses mechanical means, uses three-layer screen cloth rectangle swing sieve, and the mesh size through the swing sieve screen cloth difference is categorised the wood shavings according to geometric dimensions, and top layer wood shavings, sandwich layer wood shavings directly are used for production. The screened surface layer wood shavings and core layer wood shavings are further removed of sand and stones, foreign matters and unqualified rod-shaped wood shavings by an R-shaped wood shavings winnowing machine. And (4) sorting the agglomerated wood shavings before the core layer wood shavings enter the metering bin by using a micelle sorting device. And selecting a metering bin with a weighing and metering unit to meter the wood shavings. The metered surface layer dry wood shavings are sent into a cylindrical glue mixer with a cooling system, a rotating shaft with a cooling glue mixing claw is arranged at the center of the glue mixer, various raw materials such as glue, paraffin, curing agent and the like are mixed with the wood shavings by the cooling glue mixing claw to complete the glue application of the wood shavings, and a low-speed mixer is selected for the glue application of the core layer wood shavings. The wood shavings after glue mixing are respectively sent into a surface layer metering bin and a core layer metering bin of a paving station, and are paved through each paving head. Whole process of mating formation is through the panel density of setting for, plain board thickness and on-line monitoring's moisture content isoparametric, is carried out accurate measurement by the program operation by computer inside and is mated formation, sets up total slab balance on mating formation area. The core layer paving head is carried out by adopting a surface air flow and core layer squirrel cage throwing roller combination technology, optimal wood shaving flow distribution is adjusted by a speed and angle adjustable material distribution roller and a material distribution toothed plate, a core layer wood shaving homogeneous structure with uniformly mixed large wood shavings and small wood shavings is obtained, and the high-quality super-strong shaving board is manufactured.

The invention has the beneficial effects that: the high-quality super-strong shaving board prepared by the process has high strength, good physical and mechanical properties, higher internal bonding strength, static bending strength, elastic modulus and screw holding force, improved expansion rate of the shavings after water absorption, difficult edge breakage during secondary processing, saved shaving time, saved manpower and material resources, wider market application range, injected new vitality for the development of shaving board industry and the promotion of product competitiveness and brought vitality for the development of shaving board industry.

Detailed Description
