Problems solved by technology

[0004] 1. The wood used is all good wood, the yield of logs is less than 60%, the price is expensive, and the product cost is high
[0005] 2. The drying time is long, usually more than 20 days, which seriously restricts the batch and continuous production of products
[0006] 3. The bonding strength between the wood surface and the gypsum directly affects the appearance of the photo frame strip. If the gypsum on the surface falls off or partially falls off, it will be irreparable
[0007] 4. Timber is restricted by the national forest resource protection policy, and a large amount of wood is not conducive to environmental protection
However, through careful calculation and testing; since the paving method of the molded roulette is manual work, if the molded photo frame strips are produced one by one by manual paving, not only the quality of the photo frame strips cannot be guaranteed, but also the production efficiency, If the scale and automation cannot reach industrialized production, it is impossible to produce economic and social benefits

Embodiment 1

[0062] A method for preparing a molded molded board, comprising: sequentially processing a molded board through a raw material preparation process and a molding hot-pressing process, forming a plurality of products to be processed on the molded board, and leaving a gap between two adjacent products Cutting seam, after cutting by a cutting machine, multiple products are obtained through a forming board.

[0063] The raw material preparation process specifically includes the following steps:

[0064] a. Chip the raw material to a length of 20-30mm;

[0065] b. Pre-dry the raw materials to a moisture content below 25%;

[0066] c. Crushing the raw materials to the required thickness;

[0067] d. Dry the crushed raw materials to a moisture content of 4-5%;

[0068] e, sieve the dried raw material into surface layer material and core layer material;

[0069] f. Add glue to the surface material and the core material respectively and mix them evenly;

[0070] g. Send the mixed g...

Embodiment 2

[0096] In this embodiment, the molded photo frame strip is taken as an example to further illustrate the present invention.

[0097] A preparation method for mass-producing molded photo frame strip forming boards in an industrialized, automated and large-scale manner, including two major steps: a raw material preparation process and a forming hot-pressing process:

[0098] 1. Raw material preparation process

[0099] 1. Use a chipper to chip the raw material (bamboo or wood) to a length of 20mm;

[0100] 2. Use a dryer to pre-dry the raw materials to a moisture content of about 20%.

[0101] 3. Send the raw materials to the chip silo, and then evenly send them to the crushing equipment.

[0102] 4. Arrange multiple crushers in series. Each crusher has different sieve holes, which are distributed from large to small, and crushed step by step. The raw materials are crushed to the same thickness as that required by ordinary homogeneous particleboard for surface materials and co...

Embodiment 3

[0130] In this embodiment, the height difference on one surface of finished products such as molded dinner plates and cabinet doors does not exceed 5mm as an example to further illustrate the present invention.

[0131] A method for preparing a molded molded board, comprising: sequentially processing a molded board through a raw material preparation process and a molding hot-pressing process, forming a plurality of products to be processed on the molded board, with a cut space reserved between two adjacent products seam.

[0132] The raw material preparation process specifically includes the following steps:

[0133] a. Chip the raw material to a length of 30mm;

[0134] b. Pre-dry the raw materials to a moisture content below 25%;

[0135] c. Crushing the raw materials to the required thickness;

[0136] d. Dry the crushed raw materials to a moisture content of 5%;

[0137] e, sieve the dried raw material into surface layer material and core layer material;

[0138] f. A...

Abstract

The invention discloses a method for preparing a compression molded plate. The method comprises the steps that the molded plate is processed and prepared through a raw material preparation process and a molding hot-pressing process in sequence, a plurality of products to be processed are formed on the molded plate, and a cutting gap is reserved between every two adjacent products. According to the method, the multiple products needing to be processed can be subjected to mold pressing on the molded plate industrially and automatically on a large scale, then the molded plates are cut to obtain the single products, and the mold pressed products are produced on a large scale.

Description

technical field [0001] The invention relates to a method for preparing a molded plate, which can mass-produce molded photo frame strips, molded dinner plates and other products in an industrialized, automated and large-scale manner. Background technique [0002] Taking photo frame strips as an example, the existing wooden photo frame strips are all made of high-quality wood. In the prior art, the methods for producing wooden photo frame strips mainly include manual and semi-mechanized operations, and there is no method for molding production. The production process is as follows: After the log is remade into lumber and strips, it is dried in a drying kiln, or the wood strips are finger-joined to the length requirement, and the shape of the surface of the photo frame strip is manually processed with a four-sided planer, and then the shape of the photo frame strip is processed by a mold. Wrap a layer of plaster on the surface of the photo frame strip, and leave carved floral ...
