Description

Technical Field

[0001] This application relates to the field of logistics packaging equipment technology, specifically to a compression device for sealing and cutting heat shrink film packaging of logistics parcels. Background Technology

[0002] In logistics and distribution, some customers need a large number of similar but different items. These items are usually made up of small packages, but the quantities vary. After sorting, these items are scattered and difficult to transport, and they are easy to mix up or lose. Therefore, it is necessary to pack these items into larger packages in advance after stacking them in a certain quantity. This not only makes transportation easier but also makes them less likely to be lost.

[0003] Heat shrink film is a commonly used packaging material. After packaging, it is not only tight but also transparent, making it easy to see the contents of the package. It is inexpensive and highly praised by users, and its use is very widespread.

[0004] To facilitate heat shrink film packaging, a certain number of small packages will be stacked into a standard stack in a way that involves stacking several packages one layer at a time. For example, five small packages per layer are stacked into five layers to form a complete stack. However, since different customers require different quantities, the number of small packages in some stacks will not be exactly enough to form a complete stack. Instead, there will be a certain number of packages missing. This results in some stacks not only failing to meet the standard stack number of layers, but also the quantity in each layer may not meet the requirements for a full stack. This leads to the top layer not being a full stack.

[0005] When using heat-shrink film to package multiple small packages stacked together, the neatly stacked packages are prone to misalignment under the external force of the heat-shrink film when the film is tightened for sealing and cutting. This is especially true for the top layer of packages that are not fully covered, resulting in uneven packaging after heat shrinking, which is not conducive to subsequent transportation. Utility Model Content

[0006] In view of this, this application provides a pressing device for sealing and cutting heat-shrink film packaging of logistics parcels. When sealing and cutting the parcels with heat-shrink film, the device presses down on the parcel stack outside the heat-shrink film, which can effectively prevent the parcel stack composed of different numbers of small packages from sliding and misaligning under the external force of the heat-shrink film. During the heat-shrink film sealing and cutting process, the entire parcel stack remains neat. After subsequent heat shrinking, the parcels are neat, beautiful, and easy to transport.

[0007] According to one aspect of this application, one embodiment provides a compression device for sealing and cutting heat-shrink film packaging of logistics parcels, including a fixed connector, a guide sleeve, an upper guide rod, a linear actuator, an upper plate, a connecting rod, a middle plate, a lower guide rod, a spring rod, a spring, and a lower pressure plate. The fixed connector is provided with a linear actuator and a guide sleeve. The upper plate is provided with an upper guide rod and is connected to the linear actuator. The upper guide rod passes through the guide sleeve on the fixed connector. The linear actuator drives the upper plate to move up and down. The upper plate and the middle plate are connected by a connecting rod to fix the distance between the upper plate and the middle plate. The lower pressure plate is fixedly connected to the lower guide rod and the spring rod. A spring passes through the spring rod. The lower guide rod and the spring rod fixedly connected to each lower pressure plate form a group. The middle plate is provided with multiple sets of guide holes. The lower guide rods and spring rods on several lower pressure plates pass through the guide holes on the middle plate. The head of the spring rod is screwed with a nut so that the lower pressure plate and the middle plate are connected together. Several lower pressure plates are arranged parallel to each other.

[0008] In some embodiments, the linear actuator is one of a pneumatic cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0009] In some embodiments, in order to ensure that the upper plate remains stable during the linear actuator driving process, the number of guide sleeves on the fixed connector is at least two, and correspondingly, the number of upper guide rods on the upper plate is the same as the number of guide sleeves.

[0010] In some embodiments, the connecting rod between the upper plate and the middle plate is a rigid connecting rod, which ensures that the pressure of the linear actuator can be transmitted to the middle plate.

[0011] In some embodiments, the connecting rod between the upper plate and the middle plate is a connecting plate.

[0012] In some embodiments, a sliding sleeve is provided in the guide hole of the middle plate to allow the lower guide rod and the spring rod to slide smoothly.

[0013] In some embodiments, each of the lower pressure plates has at least two lower guide rods to ensure that the lower pressure plates are pressed down smoothly.

[0014] In some embodiments, all the lower pressure plates are at the same height after being raised.

[0015] In some embodiments, the spring is a rubber elastic tube.

[0016] In some embodiments, the upper plate, middle plate, and lower pressure plate are hollowed out to reduce weight.

[0017] This utility model discloses a packing and sealing device for heat-shrink film packaging of logistics parcels. For a parcel stack composed of multiple small packages, after the heat-shrink film is pushed onto the sealing and cutting worktable, the device is activated. A linear drive mechanism drives the upper plate downwards, which is rigidly connected to the middle plate, causing the middle plate to also move downwards. Since the lower pressure plate is slidably connected to the middle plate, it also moves downwards with the middle plate under gravity. The lower pressure plate presses onto the parcel stack through the heat-shrink film. Because the top layer of the parcel stack is not full, some lower pressure plates are not yet pressing onto the parcel stack. The linear drive mechanism continues to press down until all lower pressure plates contact the parcel stack or directly contact the sealing and cutting worktable. The linear drive mechanism continues to press down until the middle plate contacts the springs on the spring rods of all lower pressure plates, ensuring that all lower pressure plates have downward pressure under the action of the springs, thus tightly pressing down the parcel stack. At this point, the heat-shrink film is used for edge sealing and cutting, preventing misalignment of small packages in the parcel stack due to the pulling force of the heat-shrink film, resulting in neat and uniform parcels after heat-shrink film packaging.

[0018] According to the above embodiment, a pressure packing device for sealing and cutting heat-shrink film packaging of logistics parcels has several lower pressure plates that are slidably connected to a middle plate in parallel. This allows the device to be used for parcel piles of different numbers of small parcels, and the parcels are neat and aesthetically pleasing after being packaged with heat-shrink film.

[0027] Example:

[0028] In this embodiment, taking twenty-five small packages stacked in a five-layer stack as an example, i.e., stacked in a 5×5 manner, for some packages stacked with less than twenty-five small packages, if the top layer is not full, then in the next layer, there will always be small packages on top, that is, there are no other small packages on top of these small packages.

[0029] Please refer to Figure 1 and Figure 2 According to one aspect of this application, one embodiment provides a compression device for sealing and cutting heat-shrink film packaging of logistics parcels, including a fixed connector 1, a guide sleeve 2, an upper guide rod 3, a linear actuator 4, an upper plate 5, a connecting rod 6, a middle plate 7, a lower guide rod 8, a spring rod 9, a spring 10, and a lower pressure plate 11.

[0030] The fixed connector 1 is an L-shaped plate, which is made of angle iron or angle aluminum, or it can be welded from steel plate or aluminum plate. The side plate of the L-shaped plate is provided with screw holes for fixing to the crossbeam or cross frame above the sealing and cutting workbench 14 with bolts, so that the sealing and cutting device for heat shrink film packaging of logistics parcels of this utility model is located above the sealing and cutting workbench 14.

[0031] The linear actuator 4 and two guide sleeves 2 are set on the bottom plate of the L-shaped plate. The linear actuator 4 is a cylinder and is set in the middle of the bottom plate of the L-shaped plate. The two guide sleeves 2 are symmetrically set on both sides of the cylinder. The inner diameter of the two guide sleeves 2 is 18mm.

[0032] The upper plate 5 is made of steel or aluminum plate. To reduce weight, the upper plate 5 is I-shaped. The upper plate 5 is fixedly connected to the piston head of the cylinder in the middle. The upper plate 5 is fixedly connected to one end of the upper guide rod 3. There are two upper guide rods 3, which correspond to the two guide sleeves 2 on the fixed connector 1 and are respectively inserted into the two guide sleeves 2. The diameter of the upper guide rod 3 is 18mm.

[0033] The middle plate 7 is made of steel or aluminum plate. To reduce weight, the middle plate 7 is hollowed out. There are 5 sets of guide holes on the middle plate 7, with three guide holes in each set. Guide sleeves are embedded in the guide holes, and the inner hole of the guide sleeves is 8mm.

[0034] The upper plate 5 and the middle plate 6 are fixedly connected together by four connecting rods 6 set at the four corners of the upper plate 5 and the middle plate 7, so that the distance between the upper plate 5 and the middle plate 7 is fixed. The connecting rods 6 are made of steel bars with a diameter of 8mm.

[0035] In some embodiments, the upper plate 5 and the middle plate 7 are connected together by the same connecting plates at both ends, so that the distance between the upper plate 5 and the middle plate 7 is fixed.

[0036] The lower pressure plate 11 is made of steel or aluminum plate. To reduce the weight of the lower pressure plate 11, it can be regularly drilled with dense small holes. The size of the lower pressure plate 11 is smaller than the size of the small package facing upwards. Two lower guide rods 8 and a spring rod 9 are fixedly connected to the lower pressure plate 11. The spring rod 9 is located in the middle, and the two lower guide rods 8 are located on both sides of the spring rod 9. For aesthetic purposes, they can be arranged symmetrically or asymmetrically. A spring 10 is threaded through the spring rod 9. The length of the spring 10 is less than the length of the spring rod 9. When the lower pressure plate 11 is raised, the spring 10 is in a free state and is not compressed.

[0037] The two lower guide rods 8 and the spring rod 9 on the lower pressure plate 11 pass through the guide holes on the middle plate 7. To prevent the lower pressure plate 11 from falling during the lifting process, the head of the spring rod 9 is tightened with a nut. In some other embodiments, the head of the lower guide rod 8 can also be tightened with a nut, or the spring rod 9 or the lower guide rod 8 can be blocked in other ways, such as with a pin.

[0038] After the lower guide rods 8 and spring rods 9 on the five lower pressure plates 11 are inserted into the middle plate 7, the five lower pressure plates 11 are arranged in parallel to each other and are equidistant from each other. During the process of pressing the package stack, it is ensured that each lower pressure plate can press down on a small package or press it onto the sealing and cutting worktable 14.

[0039] Please refer to Figure 3 and Figure 4 A certain package stack has only three layers, with the top layer containing only three small packages located on the left. When the stack is pressed down with a heat-shrink film packaging and sealing device of this utility model, the three lower pressure plates 11 on the left press down on the top layer of small packages, that is, the three small packages 13 of the third layer, while the two lower pressure plates 11 on the right press down on the two small packages 13 on the right side of the second layer. This can achieve comprehensive pressing down on the entire package stack, preventing the heat-shrink film 12 from causing the small packages 13 to become misaligned due to the force generated by the heat-shrink film 12 during sealing and cutting, resulting in an untidy and unsightly packaged package.

[0040] This utility model discloses a heat-shrink film packaging sealing and pressing device for logistics parcels. It is used in the logistics industry to repackage small packages into slightly larger packages after sorting, facilitating efficient transportation and distribution. It can also be used for the transportation and transshipment of regular small packages in other industries.

[0041] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
