Abstract

The utility model relates to a multi-mould hot pressing former for a bamboo and wood food packaging food container, which is composed of a frame, a mould, a hydraulic and electric system and a temperature heating and controlling system. The frame comprises a vertical post, an upper cross beam, a lower cross beam and a draw rod, and the frame can be provided with decades of sets of moulds. The lower cross beam is a closed box body and is used as a hydraulic control system of oil tank; the draw rod is arranged between the upper and the lower cross beams for reinforcing the rigidity of the beams; a guide rod arranged between an upper and a lower moulds can ensure the precision of mould-closing; the lower mould is provided with an automatic demoulding mechanism; the moulds are provided with holes or grooves for installing electric heating or water heating or steam heating moulds. The utility model is suitable for in bulk producing bamboo and wood snack containers with low cost and attractive appearance.

Description

Bamboo and wood product heat pressing forming machines

The utility model belongs to a kind of mess-tin manufacturing machine, and it is hot-forming to be mainly used in mess-tin bamboo and wood product.

In order to improve environment, to protect environment not to be subjected to the pollution of waste plastic snack container,, do not see as yet that so far a kind of gratifying non-pollution snack box goes on the market in a large number though the use of plastics mess-tin in the market significantly reduces.Its main cause is that the unit of current production snack container is still capturing the production technology difficulty of string snack container, but generally still rests on the small lot trial production stage, trace it to its cause mainly be to be implemented in produce in enormous quantities on the make-up machine of multimode position difficult.

At problems of the prior art, the utility model provides a kind of multimode position make-up machine that is suitable for large-scale production.

The said bamboo and wood product of the utility model heat pressing forming machines is mainly by frame, mould, and hydraulic pressure, electric control system, temperature heating and control system are formed; Frame is the rectangular frame structure, and it comprises column 1, entablature 8, sill 2 (fuel tank of holding concurrently) and pull bar 5; In that two covers or the mould more than two covers are installed on the sill 2, the oil pressure cylinder 6 that equates with the mould number is installed on entablature 8; Mould divides two-layer up and down, and lower floor is a cover half 3, and the upper strata is to have between dynamic model 4, two moulds in order to control closing precision guide post 9; Dynamic model 4 is driven by the piston rod 7 of oil cylinder 6.All have several holes or groove 13 on cover half 3, the dynamic model 4, so that electrothermal tube or directly logical high-temperature water or steam are installed with mold heated.

The mould of tens covers and even tens covers can be set on the said bamboo and wood product of the utility model heat pressing forming machines, each mold all can satisfy material loading and blanking fast, and energy automatic heat preserving, pressurize, make the large quantities of a large amount of productions of real realization, the snack container manufacturing cost of non-environmental-pollution is reduced to bottom line.The said bamboo and wood product of the utility model heat pressing forming machines is applicable to bamboo, the processing of two kinds of materials of wood.

Fig. 1: the master of heat pressing forming machines looks schematic diagram;

Fig. 2: the schematic side view of heat pressing forming machines;

Fig. 3: the front view of counterdie.

Below the parts of the said bamboo and wood product of the utility model heat pressing forming machines are made further supplementary notes:

Operation control panel 10 can place the both sides of entablature 8, and hydraulic control circuit and temperature-control circuit are housed in it.

Sill 2 can be made the casing of enclosed shape, as the fuel tank of hydraulic system, makes compact conformation.

The effect of the pull bar 5 between the lower and upper cross-member is to avoid beam to be out of shape the too big tableware workmanship that influences when stressed.

Mould is provided with mould emptier, and it comprises the sliding pin 11 of a band back taper and is positioned at the following spring 12 of this pin.

During make-up machine work, the bamboo that at first will handle with certain specification, wood material is directly put between the upper and lower mould, then patrix move down up to the counterdie matched moulds, force bamboo, the wood material moulding, after the pressurize and insulation through certain hour, raw material just is fixed to required article.Work as Qi Mohou, sliding pin 11 under the effect of spring 12 automatically with tableware jack-up.
