Description

Technical Field

[0001] This utility model relates to the field of transport pallet technology, and in particular to a pallet for shrink film packaging. Background Technology

[0002] During the process of loading goods onto pallets and transporting pallets and goods by forklift, the goods are easily shaken and collapse, and are also easily affected by external environmental factors such as temperature and humidity. Therefore, shrink film is often used to wrap the goods and pallets to isolate the goods from the external environment, reduce the impact of external temperature and humidity on the goods, and prevent the goods from collapsing.

[0003] However, during actual transportation, the shrink film is often easily loosened and detached due to external impacts such as collisions and vibrations, thus failing to prevent the goods from collapsing or reduce the impact of external temperature and humidity. Therefore, there is a need to provide a shrink film packaging pallet that can solve the problem of the shrink film on the pallet easily loosening and detaching under external impacts in the existing technology. Summary of the Invention

[0004] The purpose of this invention is to provide a shrink film packaging tray that can solve the problem that the shrink film on the tray is easily loosened and detached under external impact in the prior art.

[0005] This utility model is implemented as follows:

[0006] A shrink-film packaging pallet includes a pallet body and a shrink film; at least two opposite surfaces of the pallet body have grooves formed therein, the lower part of the shrink film wraps around the side of the pallet body, and the shrink film is partially folded and embedded in the grooves; goods are placed on the pallet body, and the upper part of the shrink film wraps around and covers the goods.

[0007] When the pallet body is a two-way forklift pallet, the pallet body includes a top plate, a bottom plate, and three vertical plates connected between the top plate and the bottom plate, forming a two-way forklift clearance between the three vertical plates; both ends of the three vertical plates are formed with grooves, and the depth direction of the grooves is set along the length direction of the vertical plates.

[0008] When the pallet body is a four-way forklift pallet, the pallet body includes a top plate, a bottom plate, and several uprights vertically connected between the top plate and the bottom plate, with four-way forklift clearance formed between the uprights; grooves are formed on the uprights located at the edge of the pallet body, and the depth direction of the grooves is perpendicular to the axial direction of the uprights.

[0009] The grooves on the uprights located at the corners of the pallet body are L-shaped, while the grooves on the uprights located in the middle of the pallet body are straight.

[0010] The groove opening has a chamfered structure.

[0011] The chamfered structure is a 45° chamfer or a rounded R-shaped chamfer.

[0012] The groove has a depth of not less than 10mm and a width of not less than 20mm.

[0013] The distance between the groove and the top of the tray is not less than 15mm.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] 1. Because the pallet body has a groove, the shrink film can be folded and embedded in the groove, which improves the connection strength between the shrink film and the pallet body. This effectively prevents the shrink film from falling off the pallet body due to external impact during the transportation of goods, thus ensuring that the shrink film can play its role in protecting the goods.

[0016] 2. Because this utility model has a groove with a chamfered structure, it can ensure a reliable connection between the shrink film and the pallet body while preventing the shrink film from being damaged by friction with the groove opening during transportation, thus ensuring the shrink film's effect of wrapping and isolating the goods.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Please see the appendix Figure 1A shrink-film packaging pallet includes a pallet body 1 and a shrink film 3; at least two opposite surfaces of the side of the pallet body 1 have grooves 2 formed therein, the lower part of the shrink film 3 wraps around the side of the pallet body 1, and the shrink film 3 is partially folded and embedded in the grooves 2; goods 4 are placed on the pallet body 1, and the upper part of the shrink film 3 wraps around and covers the goods 4.

[0025] By setting the groove 2 on the pallet body 1, the shrink film 3 is partially folded and embedded in the groove 2, which can improve the connection and fit between the shrink film 3 and the pallet body 1, thereby reducing the risk of the shrink film 3 falling off the pallet body 1 and ensuring the transportation of goods.

[0026] Please see the appendix Figure 2 When the pallet body 1 is a two-way forklift pallet, the pallet body 1 includes a top plate 11, a bottom plate 12 and three vertical plates 13 connected vertically between the top plate 11 and the bottom plate 12, and a two-way forklift gap is formed between the three vertical plates 13; both ends of the three vertical plates 13 are formed with grooves 2, and the depth direction of the grooves 2 is set along the length direction of the vertical plate 13.

[0027] The two-way entry pallet formed by the top plate 11, bottom plate 12, and three upright plates 13 is a type of pallet in the prior art, and its specific structure will not be described in detail here. A two-way entry pallet means that the forklift forks can be inserted into its two-way entry gap from two opposite directions.

[0028] By setting grooves 2 at both ends of the three upright plates 13, the connection strength between the shrink film 3 and the three upright plates 13 can be improved, thereby preventing the shrink film 3 from falling off the two-way forklift pallet.

[0029] Please see the appendix Figure 3 When the pallet body 1 is a four-way forklift pallet, the pallet body 1 includes a top plate 11, a bottom plate 12, and a number of uprights 14 vertically connected between the top plate 11 and the bottom plate 12, forming a four-way forklift gap between the uprights 14; grooves 2 are formed on the uprights 14 located at the edge of the pallet body 1, and the depth direction of the grooves 2 is perpendicular to the axial direction of the uprights 14.

[0030] The four-way entry pallet formed by the top plate 11, bottom plate 12, and uprights 14 (usually 9 uprights) is a type of pallet in the prior art, and its specific structure will not be described in detail here. A four-way entry pallet means that the forklift forks can be inserted into its four-way entry gap from the front, back, left, and right directions.

[0031] By providing a groove 2 on the upright 14, the connection strength between the shrink film 3 and the upright 14 can be improved, thereby preventing the shrink film 3 from falling off the four-way forklift pallet.

[0032] Preferably, the groove 2 on the upright 14 located at the corner of the pallet body 1 has an L-shaped structure, and the groove 2 on the upright 14 located in the middle of the edge of the pallet body 1 has a straight structure, which can ensure the connection strength between the shrink film 3 and the upright 14 at the edge and corner.

[0033] The number of grooves 2 on a four-way entry pallet is greater than that on a two-way entry pallet, which provides a better effect in preventing the shrink film 3 from falling off.

[0034] Please see the appendix Figure 5 and attached Figure 4 The groove 2 has a chamfered structure 21 at the opening.

[0035] The chamfered structure 21 effectively prevents the shrink film 3 from being damaged by friction with the groove 2 during cargo transportation.

[0036] Please see the appendix Figure 5 and attached Figure 4 The chamfer structure 21 is a 45° chamfer or a rounded R-shaped chamfer.

[0037] The shape, size, and other structural forms of the chamfered structure 21 can also be adapted to meet actual usage requirements.

[0038] From the perspective of preventing the stretch membrane 3 from falling off, the length of the chamfered structure 21 does not exceed 30% of the depth of the groove 2.

[0039] The groove 2 has a depth of not less than 10mm and a width of not less than 20mm.

[0040] The distance between the groove 2 and the top of the tray body 1 is not less than 15mm.

[0041] The depth, width, and processing position of the groove 2, as well as the length of the chamfer structure 21, can be adjusted according to the shape and strength of the pallet body 1 to avoid the groove setting affecting the structural strength and load-bearing performance of the pallet body 1, while also enabling the groove 2 to prevent the stretch membrane 3 from falling off.

[0042] Preferably, the pallet body 1 can be made of resin materials such as polyethylene and styrene, or wood. The shrink film 3 can be made of polyethylene with a tensile strength ≥30MPa, elongation at break ≥600%, and dart impact strength ≥900g.

[0043] The shrink film 3 is wrapped around the pallet body 1 and the goods 4 in a conventional manner, which will not be described in detail here. During the wrapping process, the shrink film 3 at the groove 2 is folded and embedded into the groove 2, which can effectively prevent the shrink film 3 from falling off the pallet body 1 during the transportation of goods.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
