A new PP pallet

Abstract

This utility model relates to the field of pallet technology, specifically to a novel PP pallet, comprising a pallet body manufactured from polypropylene material by blow molding. The pallet body includes a top edge, and multiple adjustable support members are fixed at equal intervals at the bottom of the top edge. Each adjustable support member includes a support block one and a support block two, with their bottoms at the same height. The top of support block one is fixed to the corresponding position of the top edge. Support block one has an outer cutout on its outer side, and support block two has an inner cutout on its inner side. A plastic sheet is installed between support block one and support block two at the outer cutout positions. This utility model features support blocks one and two whose relationship can be rotated and changed. When stacked with materials, adjusting support blocks one and two to be stacked perpendicularly increases the stacking height of the upper and lower pallet bodies. When unloaded, adjusting support blocks one and two to be parallel and side-by-side reduces the stacking height of the upper and lower pallet bodies, allowing for the stacking of more pallet bodies.

Description

Technical Field

[0001] This utility model relates to the field of pallet technology, specifically to a novel PP pallet. Background Technology

[0002] A pallet is a standardized platform device used for the storage, handling, transportation, and stacking of goods, typically made of wood, plastic, metal, or other composite materials. Pallets can be categorized based on their application, such as storage pallets, material pallets, and transport pallets. Material pallets are widely used on production lines for the transportation and temporary storage of parts and semi-finished products.

[0003] Currently, production line pallets have different heights depending on the size of the materials. To prevent pallets from jamming and becoming difficult to separate when stacked, existing pallets are equipped with a stepped structure. When multiple pallets are stacked, the upper and lower steps limit the stacking and prevent the pallets from jamming. At the same time, it can also protect the materials inside the pallets. This stepped structure is fixed, and the stacking height of the two pallets does not change regardless of whether there are materials in the pallets. When the pallets are high, this fixed step means that when the pallets are stacked empty, it is impossible to increase the stacking quantity by adjusting the steps. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A novel PP pallet includes a pallet body made of polypropylene material by blow molding. The pallet body includes a top edge, and a plurality of adjustable support members are fixed at equal intervals at the bottom of the top edge. The adjustable support members include support block one and support block two. The bottom heights of support block one and support block two are the same. The top of support block one is fixed to the top edge at the corresponding position. Support block one has an outer cutout on the outer side of its top, and support block two has an inner cutout on the inner side of its top. A plastic sheet is installed between support block one and support block two at the outer cutout positions. The two ends of the plastic sheet are fixed to support block one and support block two at the corresponding positions.

[0006] Furthermore, the pallet body also includes a bottom plate, with outwardly oriented side plates fixed to the top four sides of the bottom plate. A receiving cavity is formed between the side plates and the bottom plate. The top edge is fixed to the outer side of the top side plate, and a flange is fixed to the bottom outer side of the top edge. The flange increases the thickness of the outer edge of the top edge, forming an obtuse angle to prevent sharpening and cutting of users.

[0007] Furthermore, both the first and second support blocks have U-shaped cross-sections, with a protrusion fixed at the bottom edge corresponding to the inner side of the second support block. The inner side of the second support block abuts against the outer side of the protrusion. The protrusion limits and fixes the second support block, preventing it from swinging freely and affecting the stacking and use of the pallet body.

[0008] Furthermore, the receiving cavity has a structure that is small at the bottom and large at the top, and the protrusion has a structure that is narrow at the bottom and wide at the top. The bottom-wide and top-narrow design of the protrusion facilitates its cooperation with the second support block. The bottom-small and top-large design of the receiving cavity is suitable for multi-layer stacking of the tray body. If necessary, it can also be set as an existing stepped design to make the receiving cavity consistent vertically. The height of this step needs to be higher than the height of the first support block to ensure the normal use of the first support block.

[0009] Furthermore, a protective pad is installed inside the receiving cavity of the tray body. The protective pad includes a bottom frame strip, which is arranged along the four sides of the bottom of the receiving cavity, and a side frame plate is fixed to the outer top of the bottom frame strip. The protective pad increases the protection of materials after they are placed in, preventing materials from sliding inside the receiving cavity.

[0010] Furthermore, through holes are provided at the four corners of the bottom plate inside the receiving cavity, and the bottom frame strip is staggered from the through holes. The through holes ensure that the inner and outer surfaces of the upper and lower tray bodies are always connected, so as to avoid affecting the rapid separation of the tray bodies when the internal sealing is not possible.

[0011] Furthermore, multiple reinforcing ribs are fixed at the bottom of the top edge, offset from those of support block one and support block two. This increases the strength of the top edge and reduces the possibility of breakage.

[0012] Furthermore, a central partition strip is fixed to the middle of the inner side of the bottom frame strip, and vertical and horizontal partition strips are fixed to the inner sides of the bottom frame strips on both sides of the central partition strip, with a gap reserved between the vertical and horizontal partition strips. This enhances the overall protective effect of the protective pad on the materials.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model is equipped with a rotatable support block 1 and a support block 2 whose relationship can be changed. When loading materials for stacking, the support block 1 and support block 2 are adjusted to be stacked vertically, which can increase the stacking height of the upper and lower pallet bodies. When unloaded, the support block 1 and support block 2 are adjusted to be parallel and side by side, which reduces the stacking height of the upper and lower pallet bodies, so as to stack more pallet bodies.

[0015] 2. In this utility model, support block one and support block two are connected by a plastic sheet, and support block two cooperates with the protrusion. The structure is simple and the operation is convenient.

[0016] 3. By setting reinforcing ribs at the top edge position, the strength of the top edge can be increased, thereby reducing the possibility of damage to the top edge in vulnerable positions and extending the service life of the entire pallet body.

[0017] 4. In this utility model, a protective pad is provided inside the receiving cavity, which can increase the safety of the material after it is put in and prevent the material from sliding inside the receiving cavity, thereby protecting the material. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] This application provides a novel PP pallet, primarily addressing the problem that current pallet designs with fixed steps to prevent upper and lower pallets from jamming lack adjustment functionality. Furthermore, these fixed steps limit the number of empty pallets that can be stacked when using taller pallets. The application provides the following technical solution, which will be discussed in conjunction with... Figures 1-6 Please provide a detailed explanation:

[0027] A novel PP pallet includes a pallet body 1, which is made of polypropylene (PP) material by blow molding. The pallet body 1 includes a bottom plate 11, and four obliquely outward side plates 12 are fixed to the top of the bottom plate 11. An accommodating cavity 17 is formed between the side plates 12 and the bottom plate 11. The accommodating cavity 17 has a structure that is small at the bottom and large at the top. A top edge 13 is fixed to the outer side of the top of the side plate 12, and a flange 14 is fixed to the bottom of the outer side of the top edge 13.

[0028] Multiple adjustable support pieces 2 are fixed at equal intervals at the bottom edge 13 near the side plate 12. The adjustable support pieces 2 include support block 1 21 and support block 22. The bottom heights of support block 1 21 and support block 22 are the same. The top of support block 1 21 is fixed to the top edge 13 at the corresponding position. Support block 1 21 has an outer cutout 25 on the outer side of its top. Support block 22 has an inner cutout 26 on the inner side of its top. A plastic sheet 24 is installed between support block 1 21 and support block 22 at the outer cutout 25. The plastic sheet 24 is made of PVC or EVA. The two ends of the plastic sheet 24 are fixed to support block 1 21 and support block 22 at the corresponding positions.

[0029] When in use, the material is placed directly into the receiving cavity 17. When multiple layers of the pallet body 1 containing the material are stacked, the adjustable support 2 is adjusted first. During adjustment, the plastic sheet 24 is used to connect the first support block 21 and the second support block 22. Combined with the toughness of the plastic sheet 24, the second support block 22 is rotated, and the outer cut 25 and the inner cut 26 are matched. The second support block 22 is placed on the first support block 21, and the outer cut 25 and the inner cut 26 are abutted, forming the connection between the first support block 21 and the second support block 22. This transforms the originally horizontally parallel first support block 21 and the second support block 22 into a vertically stacked structure, increasing the height of the adjustable support 2.

[0030] When pallet bodies 1 are stacked, the second support block 22 of the upper pallet body 1 rests on the top edge 13 of the lower pallet body 1, forming a limiting support to prevent the upper and lower pallet bodies 1 from going further in. This avoids the situation where the upper and lower pallet bodies 1 get stuck and difficult to separate. At the same time, the stacking of the first support block 21 and the second support block 22 increases the stacking height of the upper and lower pallet bodies 1, so that there is enough height space in the receiving cavity 17 to meet the storage of materials. When the materials are taken out and the pallet bodies 1 are empty and collected and stacked, the second support block 22 can be rotated and removed from the first support block 21, so that the first support block 22 can be removed from the first support block 21. The vertical stacking of pallet 1 and pallet 22 is changed to horizontal parallel arrangement, which reduces the height of adjustable support 2. At this time, when the upper and lower pallet bodies 1 are stacked, the upper pallet body 1 can be embedded deeper into the lower pallet body 1, reducing the stacking height of the upper and lower pallet bodies 1. Within a unit height, the number of pallet bodies 1 that can be stacked when pallet 1 and pallet 22 are parallel is significantly higher than the number of pallet bodies 1 that can be stacked when pallet 1 and pallet 22 are vertically stacked. Therefore, when empty pallets are stacked, each stack can hold more pallets, improving the efficiency of empty pallet transfer.

[0031] In some embodiments, the cross-sections of support block 1 21 and support block 22 are both U-shaped. A protrusion 23 is fixed at the bottom of the top edge 13 corresponding to the inner side of support block 22. The inner side of support block 22 abuts against the outer side of protrusion 23. Protrusion 23 is a structure that is narrow at the bottom and wide at the top. Support block 1 21, support block 22 and protrusion 23 are all made of plastic material.

[0032] The U-shaped structure facilitates the cooperation between support block 1 21 and support block 22, as well as the cooperation between support block 22 and protrusion 23. Protrusion 23 is used to fix support block 22. When support block 22 is fitted onto protrusion 23, it can be fixed by mutual frictional resistance, preventing support block 22 from swinging randomly and affecting the stacking of multiple pallet bodies 1. The bottom of protrusion 23 is narrow and the top is wide to facilitate the cooperation between support block 22 and protrusion 23.

[0033] In some embodiments, a protective pad 3 is installed in the receiving cavity 17 of the tray body 1. The protective pad 3 includes a bottom frame strip 31, which is arranged along the four sides of the bottom of the receiving cavity 17. A side frame plate 32 is fixed to the outer side of the top of the bottom frame strip 31. Both the bottom frame strip 31 and the side frame plate 32 are made of any one of sponge, rubber, rubber-plastic, silicone, and silicone rubber materials.

[0034] The protective pad 3 is used to separate the material from the pallet body 1 and to provide protection for the material by utilizing the soft material properties of the protective pad 3 itself.

[0035] In some embodiments, through holes 15 are provided at the four corners of the bottom plate 11 inside the cavity 17, and the bottom frame strip 31 is staggered from the through holes 15.

[0036] Although the support blocks 21 and 22 prevent jamming, if the upper and lower pallet bodies 1 are stacked too closely and the gap between them is small, they cannot be separated quickly due to atmospheric pressure. If the separation speed is too fast and the force is too great, the pallet body 1 may be damaged. The through hole 15 allows sufficient space for air to circulate inside and outside the stacked pallet bodies 1, so that they can be separated quickly without damaging the pallet bodies 1.

[0037] In some embodiments, multiple reinforcing ribs 16 are fixed at a position offset from the bottom of the top edge 13 from the first support block 21 and the second support block 22.

[0038] The reinforcing rib 16 increases the structural strength of the top edge 13. When separating, the operation is mainly carried out from the top edge 13 position. Increasing the strength of the top edge 13 can reduce the possibility of damage to the top edge 13, thereby improving the service life of the pallet body 1.

[0039] In some embodiments, a middle partition strip 33 is fixed at the middle position of the inner side of the bottom frame strip 31, and vertical partition strips 34 and horizontal partition strips 35 are fixed on the inner side of the bottom frame strips 31 on both sides of the middle partition strip 33, with a gap reserved between the vertical partition strip 34 and the horizontal partition strip 35.

[0040] The middle partition strip 33, vertical partition strip 34, and horizontal partition strip 35 are all used to increase the contact area between the protective pad 3 and the material, thereby providing better protection. The gap between the vertical partition strip 34 and the horizontal partition strip 35 is set to prevent the bottom surface of the material from being smooth and flat, making it too close to the protective pad 3, thus sealing the space between the vertical partition strip 34 and the horizontal partition strip 35 and affecting the removal of the material.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
