Problems solved by technology

This method requires more than 11 hours of thermal curing in a high-temperature tunnel kiln, and has the advantages of low investment and large output. However, there are cumbersome processes such as bamboo bundles that need to be dried first, then dipped in glue and then dried, and assembled after drying. Due to the uneven thickness of the two ends of the bamboo bundle, it is easy to cause one section of density to be too high and one section to be low in density, and the manual handling is cumbersome. Therefore, on the basis of the existing production technology of cold-pressed recombined bamboo, it is necessary to improve the production method and reduce the workload of workers. Labor intensity, improve its production efficiency and quality

Embodiment 1

[0023] The method for automatically weighing and forming blanks of cold-pressed recombined bamboo comprises the steps:

[0024] a) Drying and sorting of impregnated bamboo bundles: After the bamboo strips are dried, they are impregnated with modified low-temperature curing phenolic glue, and the bamboo bundles impregnated with phenolic glue and drained are dried on a multi-layer mesh belt dryer. Dry at 70°C until the moisture content is 14%, and sort them at the back end of the drying line to extract insect pest wood, young bamboo wood and bamboo wood with uncoordinated colors;

[0025] b) Alignment, weighing and bundling of bamboo bundles: there is an automatic weighing device below the discharge port, there are baffles on both sides of the device, and two elastic binding straps are placed at the two gaps of the baffle. There are hooks at both ends. When the bamboo bundle is piled up to 3kg, the cylinder B at both ends starts to beat the two ends of the bamboo bundle at an in...

Embodiment 2

[0029] The method for automatically weighing and forming blanks of cold-pressed recombined bamboo comprises the steps:

[0030] a) Drying and sorting of impregnated bamboo bundles. After the bamboo strips are dried, they are impregnated with modified low-temperature curing phenolic glue. The bamboo bundles impregnated with phenolic glue and drained are dried on a multi-layer mesh belt dryer. Dry at 70°C until the moisture content is 14-16%, and sort them at the back end of the drying line to extract insect-damaged wood, young bamboo wood, and bamboo wood with uncoordinated colors;

[0031] b) Alignment, weighing and bundling of bamboo bundles. There is an automatic weighing device under the discharge port. There are baffles on both sides of the device. Two elastic straps are placed at the two gaps of the baffle. There are hooks at both ends. When the bamboo bundle is piled up to 3kg, the cylinder B at both ends starts to beat the two ends of the bamboo bundle at an interval of...

Embodiment 3

[0035] The method for automatically weighing and forming blanks of cold-pressed recombined bamboo comprises the steps:

[0036] a) Drying and sorting of impregnated bamboo bundles. After the bamboo strips are dried, they are impregnated with modified low-temperature curing phenolic glue. The bamboo bundles impregnated with phenolic glue and drained are dried on a multi-layer mesh belt dryer. Dry at 70°C until the moisture content is 14-16%, and sort them at the back end of the drying line to extract insect-damaged wood, young bamboo wood, and bamboo wood with uncoordinated colors;

[0037]b) Alignment, weighing and bundling of bamboo bundles. There is an automatic weighing device under the discharge port. There are baffles on both sides of the device. Two elastic straps are placed at the two gaps of the baffle. There are hooks at both ends. When the bamboo bundle is piled up to 3kg, the cylinder B at both ends starts to beat the two ends of the bamboo bundle at an interval of ...

Abstract

The present invention proposes a method for automatically weighing and assembling cold-pressed recombined bamboo, which includes the following process steps: (1) drying and sorting bamboo bundles soaked in glue; (2) alignment weighing and bundling of bamboo bundles; (3) Automatic stacking of bamboo bundles; (4) Moisture content balance and paving of bamboo bundles. Advantages: the present invention utilizes the existing drying and sorting line of dipped bamboo bundles to carry out on-line weighing, and bundles them, and after bundling, they are automatically stacked by a roller and a lifting device, and the moisture content is balanced, and then the two bundles are Or four bundles are sent into the billet trough, using this process to improve the existing cold-pressed recombined bamboo production technology, optimize its production process, improve the uniformity of cold-pressed recombined bamboo paving, reduce the labor intensity of employees, improve production efficiency and Quality guarantees the healthy development of cold-pressed bamboo recombined bamboo.

Description

technical field [0001] The invention relates to a method for automatically weighing and assembling cold-pressed recombined bamboo, which belongs to the technical field of wood-based panel manufacturing in the wood industry. Background technique [0002] Recombined bamboo (also known as bamboo recombined wood, heavy bamboo) is a new type of bamboo wood-based panel for structure and decoration that has been improved and enhanced on the basis of bamboo laminates. The main production process of recombined bamboo is to remove the bamboo green layer from the bamboo, and then planing the bamboo yellow, rolling and sewing to make special bamboo strips (also called bamboo bundles) with through gaps, dipping, drying, and cold pressing Molding - heat curing or hot press molding, producing a density of 1.0g / cm 3 And above the bamboo heavy timber. The so-called cold forming-heat curing method means that the impregnated bamboo bundles (rolled and seamed bamboo strips) are molded in a st...
