Description

Technical Field

[0001] This invention relates to the field of insulated boxes, and particularly to a method for manufacturing an insulated box and an insulated box itself. Background Technology

[0002] An insulated box is a container that uses an insulated structure and a sealed design to slow down heat exchange between the inside and outside of the box, thereby maintaining a relatively constant internal temperature. It can be used for both heat preservation and cold preservation. Vacuum insulation panels are a high-efficiency thermal insulation composite material made based on the principle of vacuum insulation, and are among the materials with the lowest thermal conductivity currently available.

[0003] To improve the insulation effect of insulated boxes, some existing technologies disclose insulated boxes that use vacuum insulation panels as the insulation layer. For example, patent application number 202011354405.7 discloses a cold chain logistics insulated box using vacuum insulation panels, and patent application number 201710970598.0 discloses an ultra-low temperature vacuum insulation panel insulated box. Existing technologies typically use a tape wrapping process to manually fix the vacuum insulation panels to the inner liner of the insulated box, which is inefficient. Summary of the Invention

[0004] Based on the above-mentioned problems existing in the prior art, one objective of this application is to provide a method for manufacturing an insulated box, which involves wrapping a heat-shrinkable sleeve around the outside of a vacuum insulation board, and then heating the heat-shrinkable sleeve. The heat-shrinkable sleeve shrinks, causing adjacent vacuum insulation boards to press tightly together. This method is more efficient than the traditional tape wrapping process, and the gaps between the vacuum insulation boards are smaller, resulting in better insulation performance of the insulated box.

[0005] The second objective of this application is to provide an insulated box.

[0006] The technical solution adopted by this application to solve its technical problem is: a method for manufacturing an insulated box, comprising the following steps:

[0007] Step 1: Prepare the inner liner, side vacuum insulation panels, bottom vacuum insulation panels, heat shrink sleeve, and box body;

[0008] Step 2: Fix the side vacuum insulation panels to the outer wall of the inner liner, with the sides of adjacent side vacuum insulation panels abutting each other.

[0009] Step 3: Place the bottom vacuum insulation panel on the outside of the bottom wall of the inner liner, so that the periphery of the bottom vacuum insulation panel abuts against the end of the side vacuum insulation panel.

[0010] Step 4: Place the heat shrink sleeve on the outside of the side vacuum insulation panel, with the end of the heat shrink sleeve protruding beyond the bottom vacuum insulation panel.

[0011] Step 5: Heat the heat shrink sleeve, and the heat shrink sleeve shrinks. The heat shrink sleeve located outside the side vacuum insulation board forms the side heat shrink part, and the heat shrink sleeve protruding from the bottom vacuum insulation board forms the bottom heat shrink part. The bottom heat shrink part and the side heat shrink part cover the bottom vacuum insulation board and the side vacuum insulation board.

[0012] Step 6: Assemble the inner liner, side vacuum insulation board, bottom vacuum insulation board, and heat shrink tubing into the box, ensuring that the outer side of the side heat shrink tubing is close to the inner wall of the box and the outer side of the bottom heat shrink tubing is close to the inner bottom wall of the box.

[0013] Furthermore, the inner liner includes a body and a limiting edge, with a groove formed between the body and the limiting edge; the end of the side vacuum insulation plate is inserted into the groove, so that one side of the side vacuum insulation plate abuts against the outer wall of the inner liner, and the other end of the side vacuum insulation plate abuts against the inner wall of the limiting edge, thus fixing the side vacuum insulation plate to the outer wall of the inner liner.

[0014] Furthermore, the heat shrink sleeve is a PVC heat shrink sleeve.

[0015] Furthermore, the bottom vacuum insulation panel is set as one piece, and the side vacuum insulation panels are set as four pieces; both the bottom vacuum insulation panel and the side vacuum insulation panels are rectangular vacuum insulation panels.

[0016] Furthermore, the inner liner is made of blister packaging; the outer casing is made of EPP material.

[0017] Furthermore, in step two, the inner liner is inverted, and then a robotic arm is used to pick up the side vacuum insulation panel and insert the end of the side vacuum insulation panel into the slot.

[0018] Furthermore, in step three, a robotic arm is used to pick up the bottom vacuum insulation panel and place it on the outer side of the bottom wall of the inner liner.

[0019] Furthermore, in step four, a bagging device is used to cover the heat shrink sleeve on the outside of the side vacuum insulation panel; the bagging device includes multiple movable support rods, which expand the heat shrink sleeve and then move to cover the heat shrink sleeve on the outside of the side vacuum insulation panel.

[0020] Furthermore, in step five, a heating device is used to heat the sides and top of the heat shrink sleeve at a temperature of 90°C to 100°C. The heating device can be a hair dryer, a heat gun, or an oven.

[0021] Furthermore, a conveying device is used to transport the inverted inner liner to the manual machine station, the bagging device station, and the heating device station.

[0022] Furthermore, it also includes a lid, which is set on the box body.

[0023] The technical solution adopted by this application to solve its technical problem is: an insulated box, which is manufactured using the manufacturing method described above.

[0024] The beneficial effects of this application are as follows: When manufacturing the insulation box, the side vacuum insulation panels are fixed to the outer wall of the inner liner, and the bottom vacuum insulation panel is placed on the outer side of the bottom wall of the inner liner, so that adjacent vacuum insulation panels are close together. Then, a heat shrink sleeve is fitted over the outside of the side vacuum insulation panels. The heat shrink sleeve is heated, and during the heating process, it shrinks. During the shrinkage process, the heat shrink sleeve applies pressure to the side and bottom vacuum insulation panels, thereby making the sides of the adjacent two vacuum insulation panels tightly pressed together, and the ends of the side vacuum insulation panels tightly pressed against the periphery of the bottom vacuum insulation panel. This effectively reduces the gaps between the vacuum insulation panels and improves the insulation effect. Compared with the traditional tape wrapping process, the process of fitting the vacuum insulation panels with heat shrink sleeves and then heating them is more efficient. Attached Figure Description

[0033] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 6As shown, a method for manufacturing an insulated box according to the present invention includes the following steps: Step 1, preparing an inner liner 1, side vacuum insulation panels 2, bottom vacuum insulation panels 3, heat shrink sleeves 4, and a box body 5; Step 2, fixing the side vacuum insulation panels 2 to the outer side wall of the inner liner 1, with adjacent side vacuum insulation panels 2 abutting together; Step 3, placing the bottom vacuum insulation panels 3 on the outer side of the bottom wall of the inner liner 1, so that the periphery of the bottom vacuum insulation panels 3 abuts against the ends of the side vacuum insulation panels 2; Step 4, fitting the heat shrink sleeves 4 onto the outer side of the side vacuum insulation panels 2, with the ends of the heat shrink sleeves 4 protruding... Step 5: Heat the heat shrink sleeve 4 to shrink it. The heat shrink sleeve 4 located outside the side vacuum insulation board 2 forms a side heat shrink part 41, and the heat shrink sleeve 4 protruding from the bottom vacuum insulation board 3 forms a bottom heat shrink part 42. The bottom heat shrink part 42 and the side heat shrink part 41 cover the bottom vacuum insulation board 3 and the side vacuum insulation board 2. Step 6: Assemble the inner liner 1, the side vacuum insulation board 2, the bottom vacuum insulation board 3, and the heat shrink sleeve 4 into the box body 5, so that the outer side of the side heat shrink part 41 is close to the inner side wall of the box body 5, and the outer side of the bottom heat shrink part 42 is close to the inner bottom wall of the box body 5.

[0035] Thus, the present invention relates to a method for manufacturing an insulated box. During manufacturing, a side vacuum insulation panel 2 is fixed to the outer wall of the inner liner 1, and a bottom vacuum insulation panel 3 is placed on the outer side of the bottom wall of the inner liner 1, bringing adjacent vacuum insulation panels together. A heat-shrink sleeve 4 is then fitted over the outside of the side vacuum insulation panel 2. The heat-shrink sleeve 4 is heated, causing it to shrink. This shrinkage applies pressure to the side vacuum insulation panel 2 and the bottom vacuum insulation panel 3, causing the sides of the adjacent side vacuum insulation panels 2 to press tightly together, and the ends of the side vacuum insulation panel 2 to press tightly against the periphery of the bottom vacuum insulation panel 3. This effectively reduces gaps between the vacuum insulation panels, resulting in better insulation. Compared to the traditional tape wrapping process, the process of applying a heat-shrink sleeve to the vacuum insulation panel and then heating it is more efficient.

[0036] In this embodiment, the inner liner 1 includes a body 11 and a limiting edge 12, and a groove 13 is formed between the body 11 and the limiting edge 12. The end of the side vacuum insulation plate 2 is inserted into the groove 13, so that one side of the side vacuum insulation plate 2 abuts against the outer wall of the inner liner 1, and the other end of the side vacuum insulation plate 2 abuts against the inner wall of the limiting edge 12, thereby fixing the side vacuum insulation plate 2 to the outer wall of the inner liner 1.

[0037] By setting the main body 11 and the limiting edge 12, a slot 13 is formed between the main body 11 and the limiting edge 12. The end of the side vacuum insulation plate 2 is inserted into the slot 13, thus completing the fixation of the side vacuum insulation plate 2. No additional glue is needed for fixation, making the manufacturing process simpler.

[0038] In this embodiment, the heat shrink sleeve 4 is a PVC heat shrink sleeve 4, and the heating temperature of the PVC heat shrink sleeve 4 is 90°C to 100°C. The PVC heat shrink sleeve 4 is a protective material made of polyvinyl chloride that can shrink tightly to cover the surface of an object after heating. The PVC heat shrink sleeve 4 will begin to shrink at a temperature of 90°C to 100°C (such as when heated by a hair dryer, heat gun, or oven), tightly adhering to the surface of the object being covered, forming a protective film, which can effectively protect the vacuum insulation panel.

[0039] In this embodiment, the bottom vacuum insulation panel 3 is set as one piece, and the side vacuum insulation panels 2 are set as four pieces; both the bottom vacuum insulation panel 3 and the side vacuum insulation panels 2 are rectangular vacuum insulation panels, so that the insulated box is rectangular in shape, which is convenient to use.

[0040] In this embodiment, the inner liner 1 is a thermoformed inner liner 1, and the box body 5 is an EPP box body 5. The EPP box body 5 has a low density, excellent elasticity and impact resistance, and can effectively absorb vibration. Moreover, it has good resilience after being compressed and is not easily deformed, thus effectively protecting the vacuum insulation board inside the box from damage.

[0041] Further, in step two, the inner liner 1 is inverted, and then a robotic arm is used to pick up the side vacuum insulation panel 2 and insert the end of the side vacuum insulation panel 2 into the slot 13. In step three, a robotic arm is used to pick up the bottom vacuum insulation panel 3 and place the bottom vacuum insulation panel 3 on the outer side of the bottom wall of the inner liner 1.

[0042] By inverting the inner liner 1, it is easier to assemble the side vacuum insulation panel 2 and the bottom vacuum insulation panel 3. The assembly is carried out by using a robotic arm, which is an automatic operating device that can mimic the movements of a human hand and arm. Its core feature is that it can complete tasks such as grasping and carrying through programming, combining the flexibility of a human with the durability of a machine. The robotic arm can be equipped with suction cups and other suction mechanisms to accurately assemble the side vacuum insulation panel 2 and the bottom vacuum insulation panel 3.

[0043] In this embodiment, in step four, a bagging device is used to put the heat shrink sleeve 4 on the outside of the side vacuum insulation plate 2. The bagging device includes multiple movable support rods. After the multiple support rods open the heat shrink sleeve 4, the multiple support rods move to put the heat shrink sleeve 4 on the outside of the side vacuum insulation plate 2.

[0044] By using a bagging device to cover the outside of the side vacuum insulation panel 2, the heat shrink sleeve 4 is highly automated, reducing labor costs. During the bagging process, the size formed by the heat shrink sleeve 4 is slightly larger than the size formed by the side vacuum insulation panel 2, such as the distance between the inner side of the heat shrink sleeve 4 and the outer side of the side vacuum insulation panel 2 being 1mm-3mm, which facilitates bagging. After the heat shrink sleeve 4 is heated and shrunk, it can fit tightly against the outer surface of the side vacuum insulation panel 2.

[0045] Furthermore, in step five, a heating device is used to heat the sides and top of the heat shrink sleeve 4 at a temperature of 90°C to 100°C. The heating device can be a hair dryer, a heat gun, or an oven. At this temperature, the heat shrink sleeve 4 can shrink well and is less likely to be damaged.

[0046] In this embodiment, a conveying device is used to transport the inverted inner liner 1 to the manual station, the bagging device station, and the heating device station. By setting up a conveying device, the inner liner 1 and the vacuum insulation plate set on the inner liner 1 can be transported, resulting in a high degree of automation and high production efficiency.

[0047] Furthermore, it also includes a lid 6, which is set on the box body 5. By setting the lid 6, a vacuum insulation board can also be set on the lid 6, so that after the lid 6 is fixed on the box body 5, the insulation performance of the insulated box is good.

[0048] This application also discloses an insulated box manufactured using the above-described method. The insulated box has good insulation performance, and the manufacturing efficiency is higher by using a heat-shrink sleeve on the vacuum insulation board followed by heating.

[0049] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
