Wood-plastic mould pressing production line

Abstract

The invention discloses a wood-plastic mould pressing production line, comprising a feeder, a hot-press forming device, two refrigeration shaping devices and a transfer system, wherein the hot-press forming device is provided with an upper heating plate and a lower heating plate; a liftable single mould frame is arranged between the two heating plates; the two refrigeration shaping devices are respectively arranged at the two sides of the hot-press forming device and are connected by the transfer system; and the transfer system comprises a conveying chain and two supporting plates installed on the conveying chain, one supporting chain is arranged between the lower heating plate of the hot-press forming device and the single mould frame, and the other supporting plate is arranged on one of the two refrigeration shaping devices. The wood-plastic mould pressing production line in the invention adopts single heat and double cold configuration so as to enable hot-press forming and refrigeration shaping to operate simultaneously; and in addition, the mould of the single mould frame only takes part in the hot-press forming and drops out of the refrigeration shaping, and heating is never required after primary preheating. Therefore, the wood-plastic mould pressing production line can be applied in producing wood-plastic plates with high xylon content, saves energy, improves efficiency, lowers production cost and equipment cost and has strong product xylon texture.

Description

technical field [0001] The invention relates to a molding equipment for plate pressing, in particular to a wood-plastic molding production line. Background technique [0002] As a new type of green product, wood-plastic has become a focus of market attention and enterprise development in recent years. At present, most wood-plastic products adopt the production process of extrusion molding. However, because wood flour or other biomass materials are rough, have high friction, and poor fluidity, the proportion of plastic must be more than 70% and the proportion of wood must be less than 30% for normal production. As a result, the proportion of plastic used is large, the effect of wood is not ideal, the production cost is high, and the operating conditions of many enterprises are not optimistic. [0003] If the production process of compression molding is adopted, only the mold can be used to produce the plate of the specified size. Because the binder of wood-plastic board is...

AI Technical Summary

Problems solved by technology

[0004] 1. High energy consumption: the mold needs to be heated and preheated, and the plate needs to be cooled and shaped after being pressed. Repeated heating and cooling of a set of nearly 100 kg molds will result in huge energy consumption;

[0005] 2. Low efficiency: It takes about 30 minutes to preheat the mold to the set temperature, which greatly reduces the production efficiency;

[0006] 3. High cost: large equipment investment and large floor space
