Description

Technical Field

[0001] This utility model belongs to the technical field of logistics packaging devices, specifically a wrapping film packaging device. Background Technology

[0002] In modern logistics, warehousing, and manufacturing, the efficiency and stability of cargo packaging are key factors affecting supply chain operations. Stretch wrapping, a common packaging method, is widely used for securing, dustproofing, moisture-proofing, and protecting various goods during transport due to its low cost, ease of operation, and strong sealing properties. With the development of automation technology, traditional manual packaging methods are gradually upgrading to mechanized and semi-automated equipment to meet the demands of large-scale production and efficient logistics. However, current stretch wrapping devices on the market still have certain limitations in structural design and functional implementation, especially in the coordination between the wrapping rotation mechanism and the film unwinding mechanism. It is difficult to simultaneously ensure ease of operation, uniform wrapping, and equipment stability, leading to problems such as low efficiency and inconsistent packaging quality in practical applications, thus hindering the automation upgrade of the packaging process.

[0003] The main shortcomings of existing wrapping film packaging devices are concentrated in two aspects: First, the design of the package fixing and rotation structure is unreasonable. Most devices use a fixed platform to support the package, requiring manual rotation. This not only increases the labor intensity of operators, but also makes it difficult to control the speed and angle of manual rotation, easily leading to uneven film wrapping density, wrinkles, or blank areas, affecting the packaging seal. Second, the film unwinding and stretching processes lack a matching mechanism. Traditional devices usually mount the film tube on a support. When the package rotates, the film tube needs to overcome friction to rotate, which can easily cause jamming, tearing, or even film breakage due to uneven tension, resulting in material waste and packaging interruption. Based on the above problems, it is urgent to achieve coordinated linkage between package rotation and film unwinding through structural optimization to improve the efficiency and reliability of the packaging process.

[0004] A film clamping mechanism for a wrapping machine is disclosed in patent application number CN202421692180.X. In this structure, the fixing component uses a first spring to push a fixing block to clamp the film roll. However, if the inner diameter of the roll deviates significantly, the spring force is difficult to adjust adaptively, potentially leading to insecure roll fixing or excessive rotational resistance. When the wrapping turntable rotates, the film is prone to jamming and tearing, thus affecting the efficiency and reliability of the wrapping process. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] A film wrapping device, such as Figure 1 As shown, the system includes a base 1, a support column 2, a fixing column 8, a wrapping tray 4, and a film tray 5. The support column 2 and the fixing column 8 are fixedly connected to the base 1. The wrapping tray 4 is rotatably connected to the top of the support column 2 and is used to hold packages. The film tray 5 is rotatably connected to the top of the fixing column 8, and an mounting rod 6 is fixedly connected to the center of the top of the film tray 5. The mounting rod 6 is used to install the film tube. Specifically, in use, the package is placed on the wrapping tray 4, and the film tube is inserted into the mounting rod 6 on the film tray 5. The film on the film tube is pulled out and wrapped around the package. The package can then be fully wrapped by rotating the wrapping tray 4. After wrapping, the film can be cut. This method allows for quick and easy covering of packages with film.

[0030] In a preferred embodiment, such as Figure 1 As shown, the base 1 has casters 3 at its bottom and a push handle 7 on one side. The casters 3 are designed to facilitate the movement of the device and allow for flexible position adjustment. The push handle 7 provides a point of force to facilitate the movement of the device and improves operational convenience.

[0031] In a preferred embodiment, such as Figure 2As shown, a first connector 9 is provided at the top of the support column 2, and a bearing is provided between the first connector 9 and the support column 2. The first connector 9 is rotatably connected to the support column 2 through the bearing. The parcel tray 4 is detachably connected to the first connector 9, and the parcel tray 4 is rotatably connected to the support column 2 through the first connector 9 and the bearing. Further optimized, the parcel tray 4 and the first connector 9 are connected by bolts. The bearing reduces rotational friction, making the rotation of the parcel tray 4 smoother. The detachable connection via bolts facilitates the disassembly and assembly of the parcel tray 4, making it convenient for maintenance, replacement, or adaptation to parcels of different sizes.

[0032] In a preferred embodiment, such as Figure 2 As shown, a second connector 10 is provided at the top of the fixing column 8. A bearing is provided between the second connector 10 and the fixing column 8, and the second connector 10 is rotatably connected to the support column 2 through the bearing. The film tray 5 is detachably connected to the second connector 10, and the film tray 5 is rotatably connected to the fixing rod through the second connector 10 and the bearing. Further optimized, the film tray 5 and the second connector 10 are connected by bolts. The bearing design reduces rotational resistance, allowing the film tray 5 to rotate more flexibly. The detachable connection via bolts facilitates the disassembly and assembly of the film tray 5, and facilitates the replacement of the film tray 5 or maintenance of components.

[0033] In a preferred embodiment, such as Figure 3 as well as Figure 4 As shown, an auxiliary fixing mechanism 12 is provided on the side of the base 1 near the support column 2; the auxiliary fixing mechanism 12 includes a support frame 14, a fixing claw 13, a movable rod 17, a clamping member 16, and a pressing head 15; the fixing claw 13 is fixed to the bottom of the support frame 14 and connected to the base 1; the movable rod 17 is movably connected to the top of the support frame 14, and the pressing head 15 is rotatably connected to the bottom of the movable rod 17; the clamping member 16 is connected to the top of the support frame 14 and is used to clamp the movable rod 17.

[0034] During the film wrapping process, the centrifugal force generated by the rotation of the package tray 4 or the film tension can cause the package to shift, tip over, or become loosely secured, affecting wrapping efficiency and package stability. The clamping and limiting functions of the auxiliary fixing mechanism 12 ensure that the package remains in a fixed position during rotation, improving packaging reliability.

[0035] The fixed claw 13 is fixedly connected to the base 1 by bolts, thereby fixing the support frame 14 to the base 1. When wrapping with film, the movable rod 17 is lowered by releasing the clamping member 16, and the pressing head 15 at the bottom of the movable rod 17 presses the package onto the wrapping tray 4, effectively preventing the package from shifting during the wrapping process. After the package is wrapped, the clamping member 16 is released, pushing the movable rod 17 and the pressing head 15 upwards, and then the clamping member 16 is used to limit the movable rod 17.

[0036] In a preferred embodiment, such as Figure 5 As shown, the clamping component 16 includes a fixed block 21, a bidirectional screw 18, a guide rod 20, a movable block 19, and a clamping block 22. The fixed block 21 is fixedly connected to the support frame 14, the bidirectional screw 18 is rotatably connected to the fixed block 21, and the threads on both sides of the bidirectional screw 18 have opposite directions. The guide rod 20 is located on both sides of the bidirectional screw 18 and is fixedly connected to the fixed block 21. There are two movable blocks 19, which are threadedly connected to both sides of the bidirectional screw 18 and slidably connected to the guide rod 20. There are two clamping blocks 22, which are located on both sides of the movable rod 17 and are fixedly connected to the movable blocks 19 respectively.

[0037] Specifically, during use, rotating the bidirectional screw 18 causes the movable blocks 19 on both sides of the screw 18 to move closer or further apart, which in turn causes the clamping blocks 22 to move closer or further apart. When the clamping blocks 22 move closer together, they clamp the movable rod 17, thus limiting its movement. The guide rod 20 ensures that the movable blocks 19 can move smoothly.

[0038] In a preferred embodiment, such as Figure 3 as well as Figure 6 As shown, a cutting mechanism 11 is provided on one side of the base 1, located between the support column 2 and the fixed column 8. The cutting mechanism 11 includes a vertical plate 31, a clamping plate 28, a connecting plate 30, a connecting rod 29, a sliding head 23, and a cutting blade 24. The vertical plate 31 is fixedly connected to the base 1, and the connecting rod 29 is movably connected to the vertical plate 31. The clamping plate 28 and the connecting plate 30 are respectively fixedly connected to the two ends of the connecting rod 29. A tension spring 26 is also provided between the connecting plate 30 and the vertical plate 31, and the two ends of the tension spring 26 are respectively fixedly connected to the vertical plate 31 and the connecting plate 30. A sliding groove 25 is provided on the vertical plate 31, and the sliding head 23 is slidably connected to the sliding groove 25. The cutting blade 24 is connected to one side of the sliding head 23.

[0039] After wrapping the film, traditional manual film tearing or scissor cutting methods are inefficient and result in uneven cuts. Furthermore, traditional cutting methods require tidying up the film after cutting before further wrapping, impacting packaging efficiency. The clamping, cutting, and automatic reset functions of the cutting mechanism 11 achieve precise film fixation, stable cutting, and rapid reset, solving the problems of low efficiency and cumbersome operation in traditional cutting methods. Specifically, in use, the pulled-out film is passed through the gap between the clamping plate 28 and the upright plate 31 before wrapping. After wrapping, the connecting plate 30 is pulled, causing the clamping plate 28 to move and clamp the film via the connecting rod 29. Then, the sliding head 23 is pulled upwards, causing the cutting blade 24 to cut the film. After cutting, the sliding head 23 is released, and the sliding head 23 and cutting blade 24 fall naturally. After the sliding head 23 and the cutting blade 24 fall naturally, the connecting plate 30 is released. The tension spring 26 causes the connecting plate 30 to automatically reset, and the clamping plate 28 also automatically resets. The gap between the clamping plate 28 and the upright plate 31 is opened, and then the film can continue to be pulled out for wrapping. Further optimized, a limiting block 27 is fixedly attached to the upright plate 31, located between the upright plate 31 and the connecting plate 30. The limiting block 27 is used to ensure the maximum gap between the clamping plate 28 and the upright plate 31.
