Description

Technical Field

[0001] This utility model relates to the field of film-coated packaging equipment technology, and in particular to a packaging equipment, an assembly, and a housing structure having the assembly. Background Technology

[0002] In the modern packaging and transportation field, laminated packaging drums, as a common packaging container, are widely used in many industries such as chemicals, food, and coatings to hold various liquids and solids. Their unique laminated structure effectively protects the internal materials, preventing leakage, moisture, oxidation, and other issues, playing a crucial role in ensuring material quality. Currently, most laminated packaging drums on the market are cylindrical. This cylindrical structure has some obvious drawbacks in practical applications. On the one hand, for example... Figure 5 As shown, cylindrical coated drums occupy a large amount of space. During bulk transportation, their shape makes it difficult to achieve tight stacking and efficient arrangement, resulting in insufficient space utilization in transport vehicles (such as truck beds and containers). Furthermore, the large space occupancy directly leads to a lack of transportation convenience. During loading and unloading, the large size and irregular shape of the cylindrical coated drums make handling relatively complex, increasing the difficulty and time cost of loading and unloading. Utility Model Content

[0003] The purpose of this utility model is to provide a packaging device, an assembly, and a housing structure having the assembly, so as to solve the problem that the space occupied by a single film-coated packaging device in the prior art is large and inconvenient for transportation.

[0004] The technical solution of this utility model is: a packaging device, including a device body;

[0005] The appliance body is flattened by pressing it into an arbitrary shape, including a pair of flat parts and arc-shaped transition parts located at both ends of the pair of flat parts.

[0006] The pair of flat portions and the pair of arc-shaped transition portions are arranged to form a continuous structure, and the two ends of the appliance body perpendicular to the length direction of the arc-shaped transition portions form strip-shaped openings.

[0007] Preferably, the device body has a laser weld seam parallel to the length direction of the arc-shaped transition portion.

[0008] Preferably, the laser weld is located within the area of ​​the flat portion.

[0009] Preferably, a coating layer is attached to the outer wall of the appliance body, the coating layer including a first coating layer that is attached to a pair of flat portions and a second coating layer that is attached to a pair of arcuate transition portions.

[0010] Preferably, the coating layer covers the outer wall of the appliance body, excluding the laser weld seam.

[0011] Preferably, the coating layer completely covers the outer wall of the device body, and the first coating layer completely covers the laser weld.

[0012] Preferably, the maximum height of the strip opening is 10-25 cm in the direction perpendicular to the end face of the flat portion.

[0013] This application also discloses an assembly including the above-described packaging device; a plurality of the packaging devices are stacked and arranged, and an isolation portion is provided between the flat portions of adjacent packaging devices.

[0014] A accommodating structure having at least one accommodating space therein, the accommodating space containing a plurality of packaging devices, each packaging device being arranged vertically, and the plurality of packaging devices being stacked horizontally within the accommodating space.

[0015] Preferably, the accommodating space is provided with a partition, which forms multiple sub-spaces within the accommodating space, and each sub-space contains multiple packaging containers stacked laterally.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] (1) This application flattens the packaging film barrel. The flat structure allows the container body to be neatly stacked, making full use of the vertical and horizontal space of the warehouse. This not only saves warehouse space, but also effectively reduces space and transportation costs during transportation, and makes loading and unloading smoother.

[0018] (2) When forming the film-coated barrel, laser welding is used to form a laser weld. The weld is a key part that connects different parts. When pressing into a flat structure, try to ensure that the laser weld is in the area of ​​the flat part to prevent excessive deformation at the laser weld from affecting the structural strength or causing leakage.

[0019] (3) The film layer adopts a full-coverage method, which has significant advantages in terms of structural integrity, aesthetics and protection. The film layer always fits the appliance body and deforms with the deformation of the appliance body. When multiple appliance bodies are stacked, an isolation part is set between the flat parts of adjacent packaging appliances to block and protect them, preventing the film layer from being damaged under the heavy pressure of stacking.

[0020] (4) During transportation, multiple stacked appliance bodies need to be placed in the accommodating structure. If the accommodating space is large, a large number of appliance bodies will be stacked in the accommodating space. The heavy appliance bodies may cause the lower appliance bodies to be excessively deformed under pressure. Therefore, by setting up partitions, multiple appropriately sized sub-spaces are formed, and an appropriate amount of appliance bodies can be stacked in each sub-space, making it safer during long-distance transportation.

[0033] The present invention will be further described in detail below with reference to specific embodiments:

[0034] To facilitate understanding, the application scenario of this application will be explained first. After a series of processing steps such as laser welding, the coated drum will form a cylindrical structure with open ends along the axial direction. Generally, in warehouses, coated drums will be stored as follows: Figure 4The coated drums are stacked in the same way as in the storage and transportation process. As can be seen, due to the hollow structure inside the coated drums, the space utilization rate of the entire space containing the coated drums is extremely low. Therefore, this application modifies the structure of the coated drums so that they can make full use of the limited space during storage and transportation.

[0035] like Figure 1 As shown, a packaging device 01 includes a device body 1; the device body 1 is flattened by pressing with an arbitrary shape (which can be cylindrical), including a pair of flat portions 11 and arc-shaped transition portions 12 disposed at both ends of the pair of flat portions 11; the pair of flat portions 11 and the pair of arc-shaped transition portions 12 are arranged to form a continuous structure, and strip-shaped openings 3 are formed at both ends of the device body 1 perpendicular to the length direction of the arc-shaped transition portions 12.

[0036] In actual scenarios, the pair of flat parts 11 are not completely parallel. Due to the characteristics of the structure itself and without support, the flat parts 11 will present a slightly wavy shape when naturally placed, but this will not affect the subsequent stacking of the main body 1.

[0037] Since the appliance body 1 must be welded to form a continuous structure during the molding process, in this embodiment, laser welding is used to weld the appliance body 1, which will form a laser weld 13 on the appliance body 1. The laser weld 13 is parallel to the length direction of the arc-shaped transition portion 12. Laser welding is used mainly because of its high welding quality, small heat-affected zone, fast welding speed, and high precision.

[0038] The laser weld 13 is a key part that connects different parts. In order to prevent excessive deformation at the laser weld 13 from affecting the structural strength or causing leakage, the laser weld 13 is set in the area where the flat part 11 is located.

[0039] like Figure 1 As shown, a coating layer 2 is attached to the outer wall of the appliance body 1. The coating layer 2 includes a first coating layer 21 that is attached to a pair of flat portions 11, and a second coating layer 22 that is attached to a pair of arc-shaped transition portions 12.

[0040] In one implementation, such as Figure 1 As shown, the coating layer 2 completely covers the outer wall of the device body 1, and consequently, the first coating layer 21 also completely covers the laser weld seam 13. In other embodiments, such as Figure 2 As shown, the coating layer 2 covers the outer wall of the appliance body 1 except for the laser weld seam 13. This is mainly because the first coating layer 21 at the laser weld seam 13 will be ablated during the laser welding process, so the first coating layer 21 cannot cover the laser weld seam 13.

[0041] The coating layer 2 is attached to the outer wall of the appliance body 1 in a fully covered manner, which has significant advantages in terms of structural integrity, aesthetics and protection. The coating layer 2 always adheres to the appliance body 1 and deforms with the deformation of the appliance body 1, which effectively protects the appliance body 1 and the weld seam and improves the service life of the structure.

[0042] As a further optimization, the maximum height of the strip opening 3 in the direction perpendicular to the end face of the flat part 11 is 10-25cm. This maximum height is mainly located at the arc transition part 12, which can be understood as the diameter of the arc transition part 12. If the maximum height of the strip opening 3 is too large, it will not have the advantage of space utilization. If the maximum height of the strip opening 3 is too small, the curvature will be greater, which will cause the appliance body 1 to be over-deformed, and thus affect the subsequent molding of the appliance body 1.

[0043] When the above-disclosed appliance body 1 is formed, firstly, a flat appliance body 1 is formed by directly applying a radial force; specifically, a cylindrical structure is placed on a workbench, a force-applying component is set above it, and after the force-applying component moves downward a rated distance, the cylindrical structure is pressed into a flat shape; secondly, a flat appliance body 1 is formed by inward expansion and stretching; specifically, a cylindrical structure is placed on a workbench, two parallel guide pillars are inserted inside the cylindrical structure, and the pair of guide pillars move away from each other, stretching the cylindrical structure into a flat shape; thirdly, the above two methods are combined, and a force is applied above simultaneously through the guiding effect of a pair of guide pillars.

[0044] This application also discloses an assembly, such as Figure 3 As shown, the package includes several packaging containers 01. To prevent the packaging containers 01 from being subjected to heavy pressure, each packaging container 01 is arranged vertically, and multiple packaging containers 01 are stacked horizontally. An isolation portion 4 is provided between the flat portions 11 of adjacent packaging containers 01 to provide a barrier and protection, preventing damage to the film layer 2 under the stack. The isolation portion 4 can be a partition or a membrane, generally corrugated cardboard or foam film.

[0045] This application also discloses a receiving structure 5, such as Figure 4As shown, at least one accommodating space 50 is formed within the accommodating structure 5. The accommodating space 50 contains a plurality of packaging containers 01, each of which is arranged vertically, and the plurality of packaging containers 01 are stacked horizontally within the accommodating space 50. During transportation, it is necessary to place the stacked containers 1 within the accommodating structure 5. If the accommodating space 50 is large, a large number of containers 1 will be stacked within it. Although each packaging container 01 is arranged vertically, in actual scenarios, it is inevitable that the packaging containers 01 will tip over, resulting in pressure between them. If too many packaging containers 01 are stacked, they may deform under pressure. Therefore, in this application, a separator 51 is provided within the accommodating space 50, forming a plurality of appropriately sized sub-spaces 52 within the accommodating space 50. Each sub-space 52 contains a plurality of packaging containers 01 stacked horizontally, preventing compression and deformation and ensuring a safer transportation process. It should be noted that, in one embodiment, the partition 51 can make each subspace 52 a completely independent space; in other embodiments, the partition 51 may not completely separate the accommodating space 50, and it can be fixed to the bottom of the accommodating structure 5 with a height of 20 to 50 cm.

[0046] Combination Figure 4 and Figure 5 A comparison shows that, within the same sized storage space 50, directly placing the coated containers within 50 results in a very limited number of containers that can be stacked. However, the device body 1 disclosed in this application, when stacked, can maximize space utilization, significantly increasing the number of containers that can be stacked. Consequently, under the same transportation cost, it can achieve a significant improvement in transportation efficiency, and the loading and unloading process is also smoother and more efficient.

[0047] Of course, after ensuring convenient transportation, an additional process is needed to restore the shape of the appliance body 1. Therefore, after the appliance body 1 is transported to its destination, it needs to be restored to a cylindrical shape. This requires the operator to pull a pair of flat sections 11, which move closer together during transportation, flattening the barrel. By applying external force to pull these flat sections 11, the distance between them can be gradually increased, allowing the appliance body 1 to initially regain a certain shape. However, simply pulling the flat sections 11 is insufficient to completely restore the cylindrical structure of the barrel. At this point, a rounding device is needed to further restore the shape. The rounding device uses a suitable size; during the stretching process, the external stretching force of the rounding device effectively ensures that all parts of the flat appliance body 1 are evenly stressed, gradually expanding outwards, thus restoring it to a cylindrical shape. Finally, the rounding device fits tightly against the inner wall of the appliance body 1. This process does not cause any damage to the appliance body 1, and after the shape restoration is complete, it can be put into subsequent use.
