Detailed Description

Specific embodiments of the present invention are described in further detail below. It should be understood that the description herein of the embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1, the structure of the high-strength paper tray provided by the invention is schematically shown. The high-strength paper pallet comprises a bottom plate 10, three first check blocks 20 arranged on the bottom plate 10 at intervals, four second check blocks 30 penetrating through one side of the first check blocks 20 at intervals, six square tubes 40 arranged on one side of the second check blocks 30 at intervals, and a top plate 50 arranged on one side of the paper tubes 40. It is conceivable that the high-strength paper tray further includes some other functional modules, such as glue modules, label modules, etc., which are known to those skilled in the art and will not be described in detail herein.

Referring to fig. 2, the bottom plate 10 and the top plate 50 have the same transverse cross section as each other and are square. The bottom plate 10 has four square openings 11 which are correspondingly arranged, and the waste paper cut by the four square openings 11 can be used for being processed and molded into the square pipe 40, so that the functions of waste utilization and material saving are achieved. And the bottom plate 10 can not place goods, and the square opening 11 can lighten the whole weight by arranging four, and is convenient for stretching into to operate during assembly. The square tube 40 is formed by mixing glue after paper pulp is processed from waste paper, so that the strength of the square tube 40 is ensured.

The plane of the first stop 20 is perpendicular to the plane of the bottom plate 10. Four first intersections 21 are formed in the edge of the first barrier 20 facing the top plate 50, and the depth of the first intersections 21 is half the height of the first barrier 20. Four first intersections 21 are matched with four second stops 30 to fix the four second stops 30. The specific manner of the combination will be described below.

Six square grooves 22 are formed in the first grid 20 facing the edge of the top plate 50 at intervals, and six square grooves 22 are used for accommodating six square tubes 40, so that the square tubes 40 can be in contact fit with the top plate 50 and are positioned at the bottom of the bottom plate 50. Four of the square grooves 22 are located at one side of the middle section of the four first intersections 21 toward the first stops 20.

The plane of the second stop 30 is perpendicular to the plane of the top plate 50. Three second intersections 31 are formed on the edge of the second barrier 30 facing the bottom plate 10, and the depth of the second intersections 31 is half of the height of the second barrier 30. The positions of the three second intersections 31 and the three first intersections 21 correspond to each other and are engaged with each other, so that the first barrier 20 and the second barrier 30 are fixed to each other.

The length direction of the first barrier 20 is perpendicular to the length direction of the second barrier 30. Since the depth of the first intersection 21 is the same as the depth of the second intersection 31, the second barrier 30 can be inserted onto the first barrier 20. Four second stops 30 are respectively inserted into four first intersections 21 on one first stop 20. Three second intersections 31 on one second barrier 30 are respectively inserted into three first barriers 20. It is conceivable that after one bottom plate 10, four first stops 20, three second stops 30, six square tubes 40 and one top plate 50 are assembled with each other, the contact portions between the two square tubes can be glued by glue, so as to prevent the fork truck from falling off in the process of transporting goods after being forked up, and further ensure the connection strength.

A U-shaped groove 32 is respectively formed between two adjacent second intersections 31 on the second stop 30. The thickness of the bottom of the U-shaped groove 32 is equal to the height of the square tube 40. Six square pipes 40 insert respectively and establish three first check keeps off 20, so when needs fork truck fork fortune goods, fork on the fork truck wear to establish U type groove 32 and when mentioning this paper tray, because square pipe 40 with roof 50 contact laminating just is located the bottom of bottom plate 50, square pipe 40 with the tank bottom of U type groove 32 is high equally, fork truck can hold the tank bottom of U type groove 32 with square pipe 40 makes the area of contact increase of this paper tray, just square pipe 40's structural strength is high for the structure of high strength paper tray is more stable, has improved bearing strength.

Please refer to fig. 3 to fig. 6 together. The bottom panel 10, the first shelf 20, the second shelf 30, and the top panel 50 are all made of corrugated paper. The first stop 20 and the second stop 30 are manufactured in the same manner, and are formed by cutting a piece of corrugated paper to form a specific shape and folding the corrugated paper for multiple times.

The first board 60 is a first board 60 before the first board 20 is folded, and the first board 60 is provided with a first inner folding line 61, a first outer folding line 62, a second inner folding line 63, a first inner folding strip 64, and a second inner folding strip 65 in sequence. The first and second

inner folding lines

61, 63, the first outer folding line 62, and the first and second

inner folding strips

64, 65 are arranged on the first cardboard 60 at equal intervals, and the distance between the first and second inner folding lines is equal to the height of the first barrier 20. The width of the first inner folded strip 64 is three thicknesses of the first cardboard 60, and the width of the second inner folded strip 65 is four thicknesses of the first cardboard 60. When the first cardboard 60 is folded, the first inner folding line 61 and the first outer folding line 62 are folded, the second inner folding line 63 is folded inwards, outwards and inwards respectively, then folded inwards along the first inner folding strip 64, and finally folded inwards along the second inner folding strip 65, so that the first stop 20 is formed after multiple folds. The side view of the first panel 20 is shown in fig. 5, and the fold lines are arranged so that the first sheet 60 can be rolled up layer by layer, thus wrapping the central sheet, resulting in a stronger structure.

The second board 70 is a second board 70 before folding, and the second board 70 is provided with a third inner folding line 71, a third inner folding strip 72, and a fourth inner folding strip 73 in sequence. The third inner folding line 71, the third inner folding strip 72, and the fourth inner folding strip 73 are arranged on the second cardboard 70 at equal intervals, and the distance between every two of them is equal to the height of the second barrier 30. The width of the third inner fold 72 is the thickness of one of the second sheets 70, and the width of the fourth inner fold 73 is the thickness of one of the second sheets 70. The second cardboard 70 is folded inwards in the same direction three times along the third inner folding line 71, the third inner folding strip 72 and the fourth inner folding strip 73, respectively, so as to form the second barrier 30.

The structural strength of the corrugated paper formed by repeated folding is improved, and the bearing capacity of the high-strength paper tray is improved. And the opening directions of the first check 20 and the second check 30 are opposite, so that the average stress is ensured.

The first and

second panels

20 and 30 are folded by corrugated paper, and the first and

second panels

20 and 30 cannot be folded 180 degrees along the first and third

inner folding lines

61 and 71 due to a certain thickness of corrugated paper. Therefore, a folding groove needs to be formed along the direction opposite to the first inner folding line 61 and the third inner folding line 71 for facilitating folding the corrugated paper, and the folding groove is not described herein.

Compared with the prior art, the high-strength paper tray provided by the invention has the advantages that the first grid block 20 and the second grid block 30 are formed by the folded corrugated paper, so that the structural strength of the paper tray is improved, and the bearing capacity of the high-strength paper tray is improved. The square tube 40 is low in manufacturing cost, materials are saved, six square tubes 40 penetrate through the square grooves 22, the contact area between a forklift and the paper tray can be increased when the forklift forks goods, the structure of the paper tray is stabilized, and the strength and the bearing capacity are improved.
