Description

Technical Field

[0001] This utility model belongs to the field of food transportation technology, and in particular relates to a food transportation box with an integrated vacuum insulation layer. Background Technology

[0002] With the widespread development of the logistics and transportation industry, various items are delivered through logistics transportation. However, long-distance transportation of frozen food has always been a troublesome problem. If frozen food cannot be refrigerated and preserved during long-term transportation, it will result in great losses.

[0003] The existing transport containers use ordinary insulation panels on their side walls, which have poor insulation performance. This necessitates prolonged high-power operation of refrigeration air conditioning to maintain low temperatures, leading to a significant increase in energy consumption. Loading and unloading refrigerated food is relatively cumbersome and requires speed. Moving food containers within the transport container's internal space is also cumbersome, requiring multiple people to move them back and forth. Sometimes, transport tracks need to be set up, which is inconvenient to set up, and the tracks also need to be adjusted according to the shape of the containers being transported, making handling inconvenient as well.

[0004] To address these issues, we provide an integrated vacuum insulation food transport box. Utility Model Content

[0005] The purpose of this utility model is to provide a food transport box with an integrated vacuum insulation layer. The vacuum insulation panel improves the heat preservation effect, and the conveyor belt device can transport the goods quickly and conveniently, solving the problems of poor heat preservation effect and troublesome loading and unloading in the existing system.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an integrated vacuum insulation food transport box, comprising a transport box and a refrigeration air conditioner. The rear side wall of the transport box is an outward-opening double door. Vacuum insulation panels are attached to the three inner walls, the inner walls of the double doors, and the inner top wall of the transport box. A conveyor belt device is fixedly installed in the middle of the bottom wall of the transport box. An insulating pad is laid on the bottom wall of the transport box outside the conveyor belt device. The conveyor belt device includes a transport track, a motor compartment, and a laying plate. The thickness of the insulating pad is higher than the height of the transport track. The insulating pad has multiple sets of square slots symmetrically arranged at equal intervals on both sides of the transport track. A laying plate is laid on each set of square slots. The upper surface of the laying plate is flush with the upper surface of the insulating pad, and the lower surface of the laying plate does not contact the top of the transport track. A motor compartment is fixed on the rear side wall of the transport track. A drive motor is installed in the motor compartment and drives the transport track. A refrigeration air conditioner is installed on the top wall of the transport box.

[0008] The present invention is further configured such that the vacuum insulation board includes a thermal insulation foam board, a vacuum aluminum box, and a wear-resistant waterproof cloth. The thermal insulation foam board has a plurality of aluminum box slots arranged in a matrix. The outer wall of the vacuum aluminum box is wrapped with aluminum foil and then inserted into the aluminum box slot. A plastic sheet with an interference fit is then inserted into the slot opening, so that the outer surface of the plastic sheet is flush with the outer surface of the thermal insulation foam board. After applying glue to the outer surfaces of the plastic sheet and the thermal insulation foam board, the wear-resistant waterproof cloth is adhered to the outer surfaces of the thermal insulation foam board and the plastic sheet.

[0009] The present invention is further configured such that the vacuum aluminum box includes a box body and a box cover, the box body has supporting aluminum columns arranged in a matrix, the top of the supporting aluminum columns is flush with the opening of the box body, the box cover is welded to the opening of the box body, and the box body is a vacuum cavity.

[0010] The present invention is further configured such that the thickness of the box body is 4-5cm, and the wall thickness and lid thickness of the box body are both 6-8mm.

[0011] The present invention is further configured such that the conveying track includes a roller box, a roller assembly, and a conveyor belt. The roller box has raised sidewalls on both sides near the front sidewall of the transport box. Rollers are installed at equal intervals on both sidewalls inside the roller box. Bearings are fitted onto the shafts at both ends of the rollers and are embedded in the roller box wall. A conveyor belt is fitted onto the roller assembly. The upper surface of the conveyor belt at the raised sidewall position is lower than the top of the raised sidewall, and the upper surface of the conveyor belt at the non-raised sidewall position is higher than the top of the roller box. The motor shaft inside the motor compartment is fixedly connected to the shaft of one of the rollers at the end of the transport box.

[0012] The present invention is further configured such that the laying plate includes an L-shaped plate, the L-shaped plate is laid on the top of the heightening side wall and the top of the motor compartment, and the edge of the L-shaped plate is fixed to the top of the heightening side wall and the top of the motor compartment with bolts.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model utilizes a vacuum insulation board to improve the heat preservation effect. A large-area vacuum aluminum box is inserted inside the vacuum insulation board. The side walls of the aluminum box are relatively thin, and the overall area of ​​the aluminum box is large. The heat conduction efficiency through the side walls is very low. The heat conduction rate in the vacuum position is very low. This allows the insulation foam board to have a certain heat preservation effect, while the vacuum aluminum box further isolates the heat transfer efficiency. The heat insulation pad laid on the bottom wall of the transport box is 25cm thick, which has good heat preservation and is also conducive to the installation of the transport track.

[0015] 2. In this utility model, when loading or unloading goods as needed, the cargo boxes are prevented from being transported on the transport track. When the cargo boxes are full, the transport track is covered with a paving board to support the cargo boxes, but this does not affect the transport of cargo boxes on the transport track where the paving board is not laid, making loading and unloading convenient.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model relates to an integrated vacuum insulation food transport box, comprising a transport box 1 and a refrigeration air conditioner; the rear side wall of the transport box 1 is an outward-opening double door, and vacuum insulation panels 2 are affixed to the three inner walls, the inner walls of the double doors, and the inner top wall of the transport box 1; a conveyor belt device 3 is fixedly installed in the middle of the inner bottom wall of the transport box 1; an insulating pad 4 is laid on the bottom wall of the transport box 1 outside the conveyor belt device 3; the conveyor belt device 3 includes a transport track 33, a motor compartment 34, and a laying plate 31; the thickness of the insulating pad 4 is higher than that of the transport box 1. The height of the track 33 is such that the heat insulation base pad 4 has multiple sets of square slots 41 symmetrically arranged at equal intervals on both sides of the transport track 33. Each set of square slots 41 is covered with a laying plate 31. The upper surface of the laying plate 31 is flush with the upper surface of the heat insulation base pad 4, and the lower surface of the laying plate 31 does not contact the top of the transport track 33. The transport track 33 has a motor compartment 34 fixed on the tail side wall. The motor compartment 34 is equipped with a drive motor, which drives the transport track 33 to transport. A refrigeration air conditioner is installed on the inner top wall of the transport box 1.

[0026] When loading goods, the innermost part of the transport box is not initially covered with a paving board 31. People outside the transport box place the goods at the outer end of the transport track and transport them to the innermost part. Then, the paving board 31 is laid outwards from the inside, extending a certain distance. Then, another paving board 31 is laid, and the loading of the goods box continues. This process of placing paving boards 31 one by one is carried out until the loading is completed. Similarly, when unloading, when a paving board is completely exposed, it is removed. At this point, the goods box can be placed on the exposed transport track 33. If there is no need to move the goods, they can be placed directly on the transport track until the goods are transported to the outer door position, where people outside can carry them at the door.

[0027] Vacuum insulation panel 2 has a good heat insulation effect. In addition, the heat insulation pad 4 laid on the bottom wall of transport box 1 is 25cm thick, and the height of transport track is 20-25cm. It has good heat preservation and can also facilitate the installation of transport track 33.

[0028] The vacuum insulation panel 2 includes an insulating foam board 21, a vacuum aluminum box 22, and a wear-resistant and waterproof cloth 24. The insulating foam board 21 has a plurality of aluminum box slots 211 arranged in a matrix. The outer wall of the vacuum aluminum box 22 is wrapped with aluminum foil and then inserted into the aluminum box slots 211. A plastic sheet 23 with an interference fit is then inserted into the slot opening of the aluminum box slot 211, so that the outer surface of the plastic sheet 23 is flush with the outer surface of the insulating foam board 21. After applying glue to the outer surfaces of the plastic sheet 23 and the insulating foam board 21, the wear-resistant and waterproof cloth 24 is adhered to the outer surfaces of the insulating foam board 21 and the plastic sheet 23.

[0029] The insulating foam board 21 itself has good heat insulation properties, with a thickness of 8-9cm. The aluminum box groove 211 is about 7cm thick, and its area accounts for about 80% of the entire insulating foam board 21. Therefore, the vacuum aluminum box 22 is the main component that provides heat insulation. The vacuum aluminum box 22 is vacuum-sealed (operated and installed under vacuum, or by installing a vacuum tube on the side wall of the box, starting the vacuum process, and then closing the valve inside the vacuum tube). The side wall area of ​​the vacuum aluminum box 22 is small and not thick. However, because the overall area of ​​the vacuum aluminum box 22 is also large (about 40*50cm), the heat insulation effect is excellent. A wear-resistant and waterproof cloth 24 is then used to provide wear resistance and waterproofing, and also provides some heat insulation; its thickness is 8-10mm.

[0030] The vacuum aluminum box 22 includes a box body 221 and a box cover 223. Supporting aluminum columns 222 are arranged in a matrix inside the box body 221. The top of the supporting aluminum columns 222 is flush with the opening of the box body 221. The box cover 223 is welded to the opening of the box body 221. The box body 221 is a vacuum chamber.

[0031] The supporting aluminum column 222 is long and narrow, with a width of 2-3mm and a length of about 2-3cm. The entire vacuum aluminum box 22 is about 6cm long.

[0032] The thickness of the box body 221 is 4-5cm, and the wall thickness of the box body 221 (e.g.) Figure 1 and 2 As shown, the thickness of the side walls and bottom walls and the lid 223 is 6-8mm.

[0033] The transport track 33 includes a roller box 331, a set of rollers 332, and a conveyor belt 32. The roller box 331 has raised sidewalls 333 on both sides near the front sidewall of the transport box 1. Rollers 332 are installed at equal intervals on both sidewalls inside the roller box 331. Bearings are fitted onto the shafts at both ends of each roller 332 and are embedded in the wall of the roller box 331. The conveyor belt 32 is fitted onto the set of rollers 332. The upper surface of the conveyor belt 32 at the raised sidewall 333 is lower than the top of the raised sidewall 333, while the upper surface of the conveyor belt 32 at the non-raised sidewall 333 position is higher than the top of the roller box 331. The motor shaft inside the motor compartment 34 is fixedly connected to the shaft of one of the rollers 332 at the end of the transport box 1.

[0034] The raised sidewall 333 protects the conveyor belt from compression at this location, which is also where cargo boxes are generally not transported. This location is where the drive motor is located, and raising the height facilitates the installation of a non-removable laying plate.

[0035] The laying plate 31 includes an L-shaped plate 311, which is laid on the top of the raised side wall 333 and the top of the motor compartment 34. The edges of the L-shaped plate 311 are fixed to the top of the raised side wall 333 and the top of the motor compartment 34 with bolts. The L-shaped plate 311 is a plate that does not overlap the heat insulation base pad 4 and can be fixedly integrated with the roller box 331.
