Description

Technical Field

[0001] This utility model relates to the field of insulated bags for fresh produce logistics, and in particular to an insulated bag for transporting fresh produce with a built-in absorbent and moisture-proof layer. Background Technology

[0002] Insulated bags for fresh food transportation mainly ensure the temperature stability of perishable foods during transportation through physical insulation design and the synergistic effect of ice pack refrigeration. However, existing insulated packaging bags for fresh food generally have the problem of not being airtight.

[0003] For example, a Chinese utility model patent with publication number CN206871700U discloses an insulated and environmentally friendly express packaging bag for fresh food. Although the solution achieves the function of heat preservation and insulation for fresh food through a protective film and non-woven fabric core material, the method of bonding the folded edge to the outside of the insulated bag with tape cannot seal the inside. This may lead to heat convection exchange between the high temperature outside air and the low temperature inside the insulated bag, which may ultimately shorten the preservation time.

[0004] In view of this, a fresh food transport insulated bag with a built-in water-absorbing and moisture-proof layer is proposed to solve the above problems. Utility Model Content

[0005] To solve the technical problem of sealing and preserving fresh produce in thermal bags, this utility model provides a fresh produce transport thermal bag with a built-in water-absorbing and moisture-proof layer.

[0006] This utility model is achieved using the following technical solution: a machine tool safety guard, comprising a bag body, an opening on one side of the bag body, a sealing platform around the opening, a main sealing groove on the upper side of the sealing platform, an ultrasonic sealing groove on the bottom side of the main sealing groove, an edge attached to the upper side of the bag body, a sealing mechanism on one side of the edge, and a magnetic positioning mechanism around the sealing platform.

[0007] The above technical solution can seal the annular area around the bag opening to prevent air leakage and heat loss. As a further improvement to the above solution, the sealing mechanism includes a sealing plate fixedly connected to one side of the edging, the sealing plate being configured to cooperate with the main sealing groove, and an ultrasonic sealing mechanism being provided on one side of the sealing plate.

[0008] The above technical solution can achieve the first level of sealing through the sealing plate and the main sealing groove; As a further improvement to the above solution, the ultrasonic sealing mechanism includes an ultrasonic sealing block fixedly connected to one side of the sealing plate, and the ultrasonic sealing block is configured to cooperate with the ultrasonic sealing groove. Through the above technical solution, the ultrasonic sealing block can be matched with the ultrasonic sealing groove to achieve a second level of sealing, which has obvious waterproof sealing function. As a further improvement to the above solution, the magnetic positioning mechanism includes a passive magnetic strip fixedly connected to one side of the bag body. The passive magnetic strip is distributed in a ring around the periphery of the sealing platform, and a magnetic strip adsorption mechanism is provided on the edge.

[0009] The above technical solution enables the packaging bag to be opened and closed quickly through magnetic strip adsorption. As a further improvement to the above solution, the magnetic strip adsorption mechanism includes an active magnetic strip installed on one side of the edging. The active magnetic strip is distributed in a ring around the periphery of the sealing plate, and the active magnetic strip is configured in conjunction with the passive magnetic strip.

[0010] As a further improvement to the above solution, the inner side of the bag body is provided with multiple non-woven fabric water-absorbing and expanding bags.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a magnetic positioning mechanism and an ultrasonic sealing mechanism to work together. Under the action of magnetic adsorption and pressing, the ultrasonic sealing block and the ultrasonic sealing groove can effectively seal the bag opening, preventing heat exchange with the outside world and thus reducing the freshness time. 2. This utility model achieves the function of quickly and conveniently opening the fresh food insulated bag by using a combination of passive and active magnetic strips. Compared with the commonly used adhesive or staple sealing and disassembly on the market, this utility model has the advantages of simple disassembly and convenient opening.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0015] Example: Please combine Figures 1-3 This embodiment of a machine tool safety guard includes a bag body 1, which is made of a composite material of aluminum foil non-woven fabric and aluminum foil. In this embodiment, it is about 20-25cm long, 15-20cm wide, and 10-15cm high. The middle layer is pearl cotton with excellent heat insulation performance, and the inside is covered with aluminum foil film. This structural design can effectively reduce temperature exchange. The aluminum foil heat insulation layer has the characteristics of heat insulation, waterproof and durable. In other embodiments, the outer layer is made of Oxford cloth, non-woven fabric or nylon cloth. Aluminum foil composite pearl cotton: As the core insulation layer, aluminum foil reflects heat, while pearl cotton (EPE) provides cushioning and insulation. When the two are combined, a hot meal at 65°C can be maintained for about 5 hours in an environment of -30°C. Outer fabric: High-density Oxford cloth or nylon: durable, lightweight and waterproof, suitable for frequent use; Non-woven fabric: Low cost, often used for disposable or promotional gift packaging; Durability: Tear-resistant Oxford cloth and nylon fabric, leak-proof aluminum foil layer, suitable for repeated use; Thermal insulation performance: Aluminum foil reflects heat radiation, and pearl cotton reduces heat conduction; the combination achieves efficient cold and heat insulation. Environmental friendliness: Materials used in other embodiments are recyclable (such as RPET), reducing plastic pollution; Customization: Supports different thicknesses, sizes and printing requirements to suit various catering scenarios; Referring to Figure 4, a bag opening 3 is provided on one side of the bag body 1. In this embodiment, the width of the bag opening 3 is smaller than the width of the bag body 1, and the width of the bag opening 3 is sufficient to support various fresh foods. Please combine Figure 6 As shown, a sealing platform 9 is provided around the bag opening 3. The sealing platform 9 is a platform structure that protrudes from the surface of the bag body 1. The sealing platform 9 is made of plastic and has excellent flexibility. When fresh food is stuffed into the bag opening 3, the sealing platform 9 can deform and expand the deformation size of the bag opening 3. Please combine Figure 6As shown, a main sealing groove 8 is provided on the upper side of the sealing platform 9. The main sealing groove 8 has a trapezoidal structure. Numerous experiments have shown that this type of frustum structure has better sealing performance and stronger gas flow interception performance. Please combine Figure 6 As shown, an ultrasonic sealing groove 11 is provided on the bottom side of the main sealing groove 8. The ultrasonic sealing groove 11 has a triangular groove structure. Please combine Figure 4 As shown, the upper side of the bag body 1 is connected to the edge 2, and a sealing mechanism is provided on one side of the edge 2. A magnetic positioning mechanism is provided around the sealing platform 9. The edge 2 is made of the same material as the bag body 1, the middle layer is pearl cotton with excellent heat insulation performance, and the inside is covered with aluminum foil film. Please combine Figure 6 As shown, the sealing mechanism includes a sealing plate 5 fixedly connected to one side of the edge 2. The sealing plate 5 is configured to cooperate with the main sealing groove 8. The sealing plate 5 is a trapezoidal protrusion mechanism that can be fully inserted into the inside of the main sealing groove 8. The sealing plate 5 is made of plastic and has a certain degree of toughness. Please combine Figure 6 As shown, an ultrasonic sealing mechanism is provided on one side of the sealing plate 5.

[0016] Please combine Figure 6 As shown, the ultrasonic sealing mechanism includes an ultrasonic sealing block 10 fixedly connected to one side of the sealing plate 5. The ultrasonic sealing block 10 is configured to cooperate with the ultrasonic sealing groove 11. The ultrasonic sealing block 10 has a triangular boss structure and adopts an ultrasonic structure design, which makes the sealing performance stronger. Please combine Figure 4 As shown, the magnetic positioning mechanism includes a passive magnetic strip 7 fixedly connected to one side of the bag body 1. The passive magnetic strip 7 is distributed in a ring around the sealing platform 9, and a magnetic strip adsorption mechanism is provided on the edge 2.

[0017] Furthermore, the magnetic strip method allows for quick opening and sealing of the insulated bag. Compared to the commonly used methods of sealing insulated bags with staples or tape, the magnetic strip method of this invention offers the advantages of simple and efficient opening and sealing of the insulated bag. Please combine Figure 4 As shown, the magnetic strip adsorption mechanism includes an active magnetic strip 6 installed on one side of the edge 2. The active magnetic strip 6 is distributed in a ring around the periphery of the sealing plate 5, and the active magnetic strip 6 is configured in conjunction with the passive magnetic strip 7.

[0018] The active magnetic strip 6 and the passive magnetic strip 7 magnetically attract each other, so that the sealing plate 5 and the sealing platform 9 can be squeezed together to achieve sealing. In this embodiment, a plastic fixing plate can be installed on the back side of the edge band 2 to avoid insufficient structural toughness of the edge band 2, which would result in insufficient thrust between the sealing plate 5 and the sealing platform 9. Please combine Figure 3As shown, multiple non-woven fabric absorbent expansion bags 4 are provided on the inner side of the bag body 1. In this embodiment, the outer side of the non-woven fabric absorbent expansion bag 4 is made of non-woven fabric as the outer layer material, while the inner side is filled with absorbent resin. When a frozen ice pack is placed in the bag body 1 and moisture is generated, the excess moisture in the bag can be absorbed by the non-woven fabric absorbent expansion bag 4, thereby achieving the function of moisture prevention. The implementation principle of a fresh food transport insulated bag with a built-in water-absorbing and moisture-proof layer in this application embodiment is as follows: water-absorbing resin is filled into the non-woven water-absorbing expansion bag 4, and then ice packs and fresh food are placed in it. The edge 2 is turned over so that the active magnetic strip 6 and the passive magnetic strip 7 are attracted and aligned. At the same time, the sealing plate 5 can be pressed into the main sealing groove 8, and the ultrasonic sealing block 10 can be inserted into the ultrasonic sealing groove 11, thereby achieving a long-lasting and effective seal.

[0019] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
