Description

Technical Field

[0001] This utility model relates to the field of turnover box technology, and in particular to a sealed pallet box. Background Technology

[0002] Preforms are an intermediate product in the plastic bottle production process. They are formed by injecting plastic particles into a preform mold under high temperature and pressure using a plastic injection molding machine. The preform is a bottle-shaped object that is not yet fully formed. It is usually a pre-made tubular object that has the basic shape and size of a bottle, but the bottom and mouth are not yet fully formed.

[0003] To ensure that the preforms are clean and uncontaminated during transportation and to prevent them from affecting the quality of the finished product during injection molding, turnover boxes are used for storage and transportation in most cases. These boxes provide good protection for the preforms. Since the preforms need to be kept uncontaminated before being further processed into plastic containers, sealing strips are used to enhance the airtightness of the turnover boxes to prevent external dust, impurities, or other contaminants from entering the boxes.

[0004] In daily use, existing sealing strip type turnover boxes cannot guarantee the durability of the sealing strip itself. Long-term use inevitably leads to the risk of the adhesive falling off, and replacement is difficult, which in turn leads to a decrease in the sealing performance of the turnover box, resulting in the preforms inside the turnover box being contaminated. Utility Model Content

[0005] This invention addresses the problem that existing sealing technologies cannot guarantee long-term sealing, leading to impurities entering the box and contaminating the preforms. It provides a sealed tray box.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a sealed pallet box, including a base, with two opposing sub-side pieces and two opposing female side pieces detachably installed around the top of the base, and an upper cover detachably installed on the top of the sub-side pieces and the female side pieces; the sub-side pieces include a sub-upper tube and a sub-lower tube welded to the upper and lower ends of a sub-connecting plate, and two sub-baffles are respectively welded to both sides of the sub-upper tube and the sub-lower tube, and nuts are welded to both sub-baffles; the female side pieces include a female upper tube and a female lower tube welded to the upper and lower ends of a female connecting plate, and two female baffles are respectively welded to both sides of the female upper tube and the female lower tube; the sub-side pieces and the female side pieces are connected by compression through the sub-connecting plate and the female connecting plate, and bolts are threaded through the female baffles and the sub-baffles in sequence and connected to the nuts.

[0007] Furthermore, the upper cover includes an upper cover angle iron, with guide corners installed at the four bottom corners of the upper cover angle iron. The honeycomb panel is press-fitted into the upper cover angle iron by a combination of pressure strips and fastened by rivets.

[0008] Furthermore, the guide angle has an L-shaped structure, with this L-shape tilted outward by 5°.

[0009] Furthermore, the pressure strip assembly is made of aluminum alloy.

[0010] Furthermore, the base includes a base connecting slot one and a base connecting slot two spliced ​​into a rectangular frame structure. A square tube is welded inside the rectangular frame. Base feet are welded at the four bottom corners of the rectangular frame. A base plate is installed on the top of the rectangular frame. When the base is connected to the sub-side piece and the mother side piece, the base connecting slot one and the base connecting slot two engage with the mother baffle and the sub-baffle.

[0011] Furthermore, the square tubes are spliced ​​together in a grid pattern, with a hollow center.

[0012] Furthermore, the base plate includes a base bending plate, a buffer pad, and a base baffle arranged sequentially from top to bottom; the base baffle and the buffer pad are pressed and welded to the rectangular frame through the base bending plate.

[0013] Furthermore, both the base connecting slot 1 and the base connecting slot 2 have tool insertion holes inside the slots, and the slot walls have fixing holes.

[0014] Furthermore, the engagement gap between the base connecting slot one and the base connecting slot two and the mother baffle and the daughter baffle is less than 2mm.

[0015] Furthermore, the base bending plate is made of 304 stainless steel.

[0016] The beneficial effects of this utility model are: 1. Compared with existing technologies, the sealing method without a sealing strip can effectively avoid the defects of insufficient sealing strip viscosity and the need for regular replacement, thus achieving a better sealing effect; 2. The extrusion connection between the female and male side panels and the bolt fastening structure ensure the stability of the connection of each component of the box, effectively preventing the sealing failure caused by vibration during transportation; during installation, the female and male panels can be accurately embedded into the slots of the base, which not only reduces the installation difficulty, but also ensures the firmness and sealing of the connection. 3. The detachable top cover uses a honeycomb panel as the cover and is assembled using aluminum plate strips, which balances the production cost, strength and weight of the box, making it lightweight while meeting the load-bearing requirements of the preform. 4. The inner walls of the box are made of 304 stainless steel, which is in direct contact with the preforms. This material not only has good corrosion resistance, which can effectively prevent rust and contamination caused by contact with the preforms inside the box, ensuring the purity of the preforms during transportation and storage, but also has a smooth surface that does not easily leave impurities, making it easy to clean and maintain, further ensuring the hygienic environment inside the box. The composite structure of the 5.304 stainless steel base bending plate and buffer pad effectively absorbs the impact of transportation while preventing deformation caused by metal fatigue, thus extending the overall service life of the sealed pallet box. 6. The base connecting slot has a locking gap control of less than 2mm, combined with the user-friendly design of tool insertion holes and fixing holes, which not only ensures assembly accuracy but also facilitates quick on-site disassembly and assembly operations.
