The invention will be further described below in conjunction with embodiment:
Fig. 1 is, Fig. 2 is structural representation of the present invention;
Fig. 3 is the partial enlarged drawing of Fig. 1;
Fig. 4 is the structural representation of skeleton.
Wherein: 1 core body; 2 films; 3 platforms; 4 legs; 5 grooves; 6 grooves; 7 grooves; 8 skeletons; 9 reinforced sheets; 10 perforates; 11 connectivity slots; 12 grooves; 13 times films; 14 upper films; 15 downsides; 16 upper sides.
The specific embodiment
Embodiment: as Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, a kind of high strength compound light plastic pallet, comprise platform 3 and the leg 4 that is connected platform 3 lower surfaces, the main body of described pallet is a lightweight core 1, the surface of lightweight core 1 is coated with plastic sheeting, the surface of pallet is provided with a plurality of grooves 5,6,7, the groove 5 of two adjacent leg 4 relative inner walls communicates with groove 6 between platform 3 lower surfaces and forms connectivity slot 11, connectivity slot 11 is divided into a plurality of districts with the lower surface of platform 3, at least be provided with a groove 12 in each district, film 1 comprises the following film 13 that covers platform 3 lower surfaces and leg 4, cover the upper film 14 of platform 3 upper surfaces, the side of following film 13 has extended upward downside 15, the side of upper film 14 is extended with upper side 16 downwards, and upper side 16 parts cover outside the downside 15.
Be provided with skeleton 8 in the described lightweight core 1, skeleton 8 is upright schistose texture, and cross connection is fixed in length and breadth, and sheet skeleton 8 is extended with reinforced sheet 9 downwards in the position of leg 4, and sheet skeleton 8 is provided with plurality of opening 10.
The manufacturing process of core body 1 is: put into earlier skeleton 8 in mould, the foamed plastic agent is injected in the mould again, taking-up gets final product after the moulding.Foamed plastic density is greatly about 28kg/m
3, the fusion degree more preferably greater than or equal 70%.
Vertically be provided with a plurality of grooves 5 on the sidewall of leg 4, the lower surface of platform 3 is provided with a plurality of grooves 6, the groove 5 of two adjacent leg 4 relative inner walls communicates with groove 6 between platform 3 lower surfaces and forms connectivity slot 11, connectivity slot 11 is divided into four districts to the lower surface of platform 3, and all tiltedly is provided with five parallel grooves 12 in each the inside, district of lower surface.Film 13 covers under the lead-free PVC of the lower surface of platform 3 and the regular shape of leg 4 usefulness.Following film 13 is wanted the thickness equilibrium, and greatly about 1.2mm, the side of following film 13 has extended upward downside 15.
In the centre of construction pallet, previous fore-warming film 13 down begins to contact the end wall of leg 4, and downside 15 is added by instrument and nestles up on the wall or die of the platform 3 of adjacency, is not demonstrated.Gas between following film 13 and lower surface is drawn out of by core body 1, just produces parital vacuum between lower surface and following film 13.The pressure that parital vacuum produces is reinforced in the place of needs, can stretch film 2, and so it can be adjacent on the lower surface of leg 4 and platform 3.
The upper surface of platform 3 is covered by the lead-free PVC upper film 14 of general rectangular shape.Upper film 14 is the about 0.6mm of thickness, and the side of upper film 14 is extended with upper side 16 downwards.
In the manufacturing process of pallet, fore-warming upper film 14 is clamped the upper side 16 of upper film 14 by serviceable tool, and leg is on core body 1.Core body 1 is pushed into then, and upper surface contacts with the medial surface of upper film 14.The gas that is trapped between upper film 14 and upper surface will be extracted out by core body 1.The partial vacuum that the result forms forces upper film 14 and upper surface to be adjacent to as much as possible.
When discharging the upper side 16 that is stepped up by anchor clamps, the part of not having coverage at sidewall by on pressurize and closes up, the downside 15 of following film 13 heats overlapping with the upper side of upper film 14 16.
The manufacturing materials of above-mentioned film is except using lead-free PVC, also available high impact polystyrene (HIPS) or high density polyethylene (HDPE) (HDPE) etc.
In addition, take shape in the increase of the groove 5 of leg 4 exterior lateral sides, can strengthen pallet intensity, particularly leg 4.Cargo-carring size depends on the loaded area size of pallet, i.e. the size on the surface of leg 4 end walls.Loaded area is big more, and the load-carrying capacity of pallet is strong more.
In order to increase the delelivered payload capability of loaded area and pallet, it is minimum that the distance that adjacent leg is 4 should be reduced at interval.Adjacent leg 4 minor increment at interval must be able to make two prongs of fork truck again or similarly hoisting device can be simultaneously by adjacent row's leg.Consider above-mentioned condition suggestion, the suitable distance that most platform adjacent leg are 4 is at 80 millimeters.
The intensity of pallet is relevant with the bonding degree of film 2 and core body 1, and film 2 is big more with the intensity of the tight more then pallet of the big more absorption of bond area of core body 1.The present invention adopts vacuum suction technology, in the vacuum forming process, the film 2 of heating combines with core body 1 under pressure, air between surface and core body 1 or other gas, as much as possible being excluded reaches film 2 and combines with the maximum of core body 1 along with the formation of vacuum in film 2 and core body 1 cohesive process.
The present invention in leg 4 lateral layout groove 5, strengthened leg semi-finals degree, improved load-carrying capacity; The present invention has designed some grooves 6 at the pallet lower surface, and groove 6 structures and layout have improved tray platform carrying rigidity; The present invention has designed groove 7 at tray upper surface, and groove 7 has improved the bending strength of pallet when fork truck lifts; The present invention is provided with skeleton 8 in core body 1, skeleton 8 is extended with reinforced sheet 9 downwards in the position of leg 4, and the progressive intensity of having strengthened pallet has improved load-carrying capacity.
