The manufacturing method of the light tray has the steps: (1) manufacturing the tray blank body made of light materials; (2) wrapping a layer of wear-proof outer shell on the tray blank body. The light tray of the present invention has the advantages of light weight, high intensity, wear resistance and low cost, and can be widely applied to the industries of storage, transportation, package, etc. The manufacturing method is simple.

Description

A kind of manufacture method of Light tray

Technical field

The present invention relates to the employed pallet of packing, storage and transport field, goods pad, more particularly, relate to a kind of Light tray and method for making thereof.

Background technology

In industries such as packing, storage, transportations,, generally place a pallet or a goods pad as shown in Figure 1 and Figure 2 in the bottom of goods for ease of transporting goods.During carrying, only need to hold pallet, can easily the goods on the pallet optionally be piled up anywhere with fork truck.As shown in Figure 3, it is that wooden materials is made that traditional pallet 1 mostly is by a kind of material, and the shortcoming of this Wooden tray is: 1, because the corrosion-resistant of timber, so, Wooden tray will rot to become poor after using a period of time, and has deposited many germs in the slit of timber.When export of goods, for the sanitary inspection that makes goods meets quarantine standard, will extensive work such as carry out disinfection, fumigate to this Wooden tray, time-consuming, take a lot of work, require great effort.2, in order to make this Wooden tray, will consume a large amount of timber every year.3, not attractive in appearance.This Wooden tray can't clean, so after use a period of time, appearance is messy, not attractive in appearance.

In order to overcome the shortcoming of Wooden tray, the pallet of being made by weight body materials such as duroplasts or metals has appearred again on the market.This pallet has solved problems such as Wooden tray is perishable, health quarantine nonconformity, but there is a common shortcoming too in it: the weight of self is big, the cost height.This not only makes storage rack bear too much invalid load, and has increased mechanical wear and energy consumption in portage and the transportation, causes the increasing of industry operation cost.

Summary of the invention

In view of the foregoing, the purpose of this invention is to provide a kind of method of making Light tray.

For achieving the above object, the present invention takes following design plan: a kind of manufacture method of Light tray, and it may further comprise the steps:

1., make the pallet idiosome of making by light material;

2., the pallet idiosome is placed plastics sucking moulding equipment work platform, on high impact polystyrene sheet material covering idiosome;

3., p-poly-phenyl ethene sheet material is heated to till its soft extensible equably, takes out the air between polystyrene sheet material and the pallet idiosome, under the bar pressure effect, the polystyrene sheet material closely is wrapped in the one side of pallet idiosome;

4., adopt above-mentioned same step, closely wrap up one deck polystyrene sheet material at the another side of pallet idiosome; Making whole pallet idiosome not have open ground is wrapped up by polystyrene;

5., with sharp keen blade or custom-designed dressing tool unnecessary high impact polystyrene sheet material is pruned away.

Because the present invention adopts above technical scheme, promptly, at first, make the pallet idiosome with light materials such as styrofoam or watt rib cardboard or honeycomb cardboards, then, the shell of making by high-abrasive materials such as duroplasts or glass-felt plastics at coated outside one deck of pallet idiosome, so, the present invention has the following advantages: the Light tray own wt of 1, making is light, and the cost of material is low, is easy to carrying.2, the bulk strength height of Light tray is wear-resistant, shock-resistant.Since the present invention be in the coated outside of pallet idiosome one deck make shell by high-abrasive material, so, pallet integral intensity height, wear-resistant, shock-resistant.3, health.Because the present invention uses plastic uptake technology to make, can realize that the pallet idiosome combines with the entire body of shell is seamless, so, can be not in use, in two-part junction parasitic microbe, health.4, appearance looks elegant.Normally at coated outside one deck duroplasts of pallet idiosome, the size of the material of plastics, density, thickness and color and pallet all can be adjusted as required, select in the present invention, so, the Light tray appearance looks elegant of making, beautiful.5, manufacturing process is simple.

The specific embodiment

As Fig. 4, shown in Figure 5, Light tray of the present invention mainly is made of pallet idiosome 2 and shell 3 two parts; Shell 3 is wrapped in the outside of pallet idiosome 2.

Pallet idiosome 2 is made by light material such as styrofoam or watt rib cardboard or honeycomb cardboard etc., and is just low weight by the pallet that the pallet idiosome is made so the pallet idiosome of making 2 is just low weight because these materials are low weight, is easy to carrying.

In order to increase the intensity of pallet idiosome 2, the present invention is also at coated outside one deck shell 3 of pallet idiosome 2.Shell 3 is made by high-abrasive material such as duroplasts or glass-felt plastic etc., its objective is the intensity, resistance to abrasion and the Dent resistance that strengthen pallet idiosome 2.

The manufacture method of this Light tray is:

1, makes the pallet idiosome of making by light material;

2, wrap up the anti abrasive shell of one deck in the outside of pallet idiosome by plastic uptake technology.

Below, the present invention is the manufacture method of this Light tray of raw material casehistory with styrofoam and duroplasts.

At first, be ready to mould, then, make Light tray according to following steps according to the profile and the size of the Light tray that will make.

Its concrete steps are as follows:

1, makes the pallet idiosome of making by light material

1., granules of polystyrene being placed prefoam equipment carry out prefoam handles;

2., will suck the make-up machine that mould is housed by certain density requirements through the granules of polystyrene after the prefoam processing;

3., high pressure steam imported mould force granules of polystyrene to be full of mold cavity, form styrofoam pallet idiosome through cooling.

2, wrap up the anti abrasive shell of one deck in the outside of pallet idiosome by plastic uptake technology

1., the pallet idiosome is placed plastics sucking moulding equipment work platform, on high impact polystyrene sheet material covering idiosome;

2., p-poly-phenyl ethene sheet material is heated to till its soft extensible equably, takes out the air between polystyrene sheet material and the pallet idiosome, under the bar pressure effect, the polystyrene sheet material closely is wrapped in the one side of pallet idiosome;

3., adopt above-mentioned same step, closely wrap up one deck polystyrene sheet material at the another side of pallet idiosome; Making whole pallet idiosome not have open ground is wrapped up by polystyrene;

4., with sharp keen blade or custom-designed dressing tool unnecessary high impact polystyrene sheet material is pruned away.

Below only be the manufacturing process of example explanation pallet idiosome,, can adopt the technology of bonding shaping, make the pallet idiosome if be that raw material is made the pallet idiosome with watt rib cardboard or honeycomb cardboard with the styrofoam.Then,, adopt plastic uptake technology, cooperate adhesives, at the anti abrasive shell of its surface parcel one deck on the surface of pallet idiosome.

Light tray of the present invention is in light weight, intensity is high, wear-resistant, cost is low, can be widely used in industries such as storage, transportation, packing.

Manufacture method of the present invention is simple, can change the Light tray of end product according to the grade of the shape of mould, size and the polystyrene of using, impact resistance, thickness etc. from structure.

The above only is specific embodiments of the invention and thinking, and is any based on the equivalent transformation on the technical solution of the present invention basis, all belongs within the protection domain of the present invention.
