Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of packaging equipment, and in particular to a dual-station pallet film wrapping packaging device. Background Technology
[0002] Pallet wrapping machines use a rotating turntable to rotate palletized goods, thereby wrapping and protecting them with film. This method effectively prevents dust, moisture, and scratches, and protects the goods.
[0003] In the existing technology, only one station wraps the film around the pallet. When the worker is loading the goods onto the pallet, the pallet wrapping machine needs to stop running. When the pallet wrapping machine is working on film wrapping, the worker needs to stop loading the goods onto the pallet. After the film wrapping is completed, the pallet and the goods are unloaded together, and then a new pallet is placed on the turntable for loading. This is inefficient. Utility Model Content

[0009] The beneficial effects of this utility model's dual-station pallet film wrapping packaging device are:
[0010] In use, pallets are placed on turntables for stacking and palletizing goods. Once a pallet on one turntable is loaded with goods, the end of the film is attached to the outer periphery of the goods. The turntable is rotated by a rotary drive structure, and the film unwinding mechanism moves back and forth vertically by a winding lifting mechanism to wrap the film around the outer periphery of the goods, thus achieving automatic film wrapping. At the same time, workers stack and palletize goods on another turntable. Afterward, the film-wrapped pallet is removed, and a new pallet is placed on the corresponding turntable for wrapping the film on another pallet loaded with goods. This process is repeated to continuously load goods and wrap the film, improving packaging efficiency.
[0011] As a further improvement to the above technical solution, the film unwinding mechanism includes an unwinding module, a film clamping module, and a film cutting module arranged in sequence. The unwinding module is used to clamp the film roll, the film clamping module is used to clamp and release the film, and the film cutting module is used to cut the film.
[0012] As a further improvement to the above technical solution, the unwinding module includes an unwinding shaft, one end of which is fixedly installed, and the other end is detachably fitted with a limiting sleeve.
[0013] As a further improvement to the above technical solution, the film clamping module includes two film clamping rollers arranged in parallel with each other, a clamping drive structure that drives the two film clamping rollers to move closer and further apart, and a clamping gap is formed between the two film clamping rollers for the film to pass through.

[0016] As a further improvement to the above technical solution, the hot-cutting component is a heating wire, and the cutting drive structure includes two lifting blocks arranged at intervals and two cutting drive units that drive the two lifting blocks to move synchronously. The two ends of the heating wire are respectively connected to the two lifting blocks.
[0017] As a further improvement to the above technical solution, the turntable is provided with multiple positioning slots on its surface. These multiple positioning slots are used to position and cooperate with multiple legs of the pallet so that the center of the pallet is coaxially set with the rotation center of the turntable.
[0018] As a further improvement to the above technical solution, the turntable is provided with two sliding grooves arranged side by side at intervals, one end of the two sliding grooves extending to the side of the turntable, and having an open slot.
[0019] As a further improvement to the above technical solution, the pallet rotating mechanism also includes an inclined platform disposed on the outer periphery of the turntable, the upper end of the inclined platform being connected to the two slots.

[0034] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.
[0035] Existing pallet wrapping machines have only one station for wrapping film on pallets. When workers are loading goods onto the pallets, the machine needs to stop running. Conversely, when the machine is wrapping film, workers need to stop loading goods. After the film wrapping is complete, the pallets and goods are unloaded together, and then a new pallet is placed on the turntable 111 for loading. This process is inefficient. Therefore, this invention proposes a dual-station pallet film wrapping device.
[0036] like Figure 1 As shown, the dual-station pallet film wrapping packaging device of this utility model includes: a pallet loading assembly 100 and a film wrapping assembly 200.
[0037] The pallet loading assembly 100 includes at least two pallet rotating mechanisms 110. In this embodiment, there are two pallet rotating mechanisms 110 arranged in a left-right interval and symmetrically. In other embodiments, there may be three or more pallet rotating mechanisms 110. Each pallet rotating mechanism 110 may be arranged in a front-back direction or in a circumferential ring interval.
[0038] The pallet rotating mechanism 110 includes a turntable 111 for supporting and placing pallets and a rotary drive structure 112 for driving the turntable 111 to rotate around a vertical axis. In this embodiment, the central axis of the turntable 111 is vertically arranged, and the rotary drive structure 112 drives the turntable 111 to rotate around its own axis. In use, the pallet is placed on the table surface of the turntable 111 for loading and film wrapping. When loading, the turntable 111 is fixed, while when film wrapping, the turntable 111 rotates around its own axis.
[0039] The packaging device in this embodiment also includes a base 300, and each turntable 111 is rotatably mounted on the base 300. In order to improve the load-bearing capacity of the turntable 111, an annular support slide rail 113 is provided between the base 300 and the turntable 111. The turntable 111 in this embodiment has a disc structure, and the bottom of the turntable 111 is slidably engaged with the support slide rail 113. The rotation drive structure 112 includes a rotary motor 1121. In this embodiment, the rotation output shaft of the rotary motor 1121 is coaxially connected to the bottom of the turntable 111.
[0040] The film winding assembly 200 of this utility model includes at least one film unwinding mechanism 210 disposed between at least two turntables 111, and a winding lifting mechanism 220 for driving at least one film unwinding mechanism 210 to reciprocate in the vertical direction. In this embodiment, two film unwinding mechanisms 210 are provided, and the two film unwinding mechanisms 210 correspond to two turntables 111 respectively. The winding lifting mechanism 220 synchronously drives the two film unwinding mechanisms 210 to reciprocate in the vertical direction. The film unwinding mechanism 210 is mainly used for unwinding the film.
[0041] In use, pallets are placed on turntables 111 for stacking and palletizing goods. Once a pallet on one turntable 111 is loaded with goods, the end of the film is attached to the outer periphery of the goods. The turntable 111 is rotated by the rotation drive structure 112, and the film unwinding mechanism 210 is moved back and forth in the vertical direction by the winding lifting mechanism 220 to wrap the film around the outer periphery of the goods, thereby achieving automatic film wrapping. At the same time, the worker stacks and pallets on another turntable 111 for stacking and palletizing goods. Then, the pallet with the film wrapped is taken out, and a new pallet is placed on the corresponding turntable 111. The film is then wrapped around another pallet loaded with goods. This operation is repeated to continuously load goods and wrap the film, thereby improving packaging efficiency.
[0042] like Figure 2 As shown, the film unwinding mechanism 210 of this embodiment includes an unwinding module 211, a film clamping module 212, and a film cutting module 213 arranged in sequence. The unwinding module 211 is used to clamp the film roll, the film clamping module 212 is used to clamp and release the film, and the film cutting module 213 is used to cut the film.
[0043] In use, the film roll is placed on the unwinding module 211, and the film passes through the film clamping module 212 and the film cutting module 213 in sequence before being wrapped around the outer periphery of the goods.
[0044] like Figure 1 As shown, the winding lifting mechanism 220 of this embodiment includes a lifting seat 221 and a lifting drive structure 222 that drives the lifting seat 221 to rise and fall. The lifting drive structure 222 adopts a motor + lead screw drive structure to achieve precise lifting. In some other embodiments, the lifting drive structure 222 may adopt a pulley drive structure. In this embodiment, the unwinding module 211, the film clamping module 212, and the film cutting module 213 are mounted on the lifting seat 221.
[0045] Since the film is prone to detaching from the goods during film winding, this is mainly because the film does not have a certain tensile force during winding. In this embodiment, the film clamping module 212 is used to clamp and release the film, so that the film between the goods and the film clamping module 212 has a certain tensile effect. Under the stretched state, the film can be stably wrapped around the outer periphery of the goods.
[0046] Currently, workers tear the film, which increases their workload and poses safety hazards. This is because workers need to stretch their arms between the film unwinding mechanism 210 and the goods, and tearing the film results in incomplete ends, affecting the next winding. In this embodiment, a film cutting module 213 is provided to cut the film. It can be understood that after winding is completed, the film cutting module 213 cuts the film between the film clamping module 212 and the goods.
[0047] Among them, such as Figure 2 and Figure 3 As shown, the unwinding module 211 of this embodiment includes an unwinding shaft 2111. One end of the unwinding shaft 2111 is fixedly installed, and the other end is detachably fitted with a limiting sleeve 2112. When changing rolls, the limiting sleeve 2112 is removed, the film roll is fitted onto the unwinding shaft 2111, and then the limiting sleeve 2112 is installed to limit the installation of the film roll without affecting the unwinding rotation of the film roll.
[0048] In this embodiment, the unwinding shaft 2111 is vertically arranged, the lower end of the unwinding shaft 2111 is rotatably mounted on the lifting seat 221, and the limiting sleeve 2112 is fitted onto the upper end of the unwinding shaft 2111.
[0049] The film clamping module 212 of this embodiment includes two film clamping rollers 2121 arranged in parallel with each other, and a clamping drive structure that drives the two film clamping rollers 2121 to move closer and further apart. A clamping gap is formed between the two film clamping rollers 2121 for the film to pass through. The clamping force on the film is adjusted by adjusting the distance between the two film clamping rollers 2121, so as to adjust the stretching effect of the film.
[0050] Specifically, such as Figure 2 and Figure 3 As shown, in this embodiment, the two clamping rollers 2121 are respectively arranged vertically, and the clamping drive structure includes two sliding blocks 2122 and two clamping drive units 2123 that drive the two sliding blocks 2122 to move closer and further apart from each other. The lower ends of the two clamping rollers 2121 are respectively rotatably connected to the two sliding blocks 2122. The two sliding blocks 2122 are slidably mounted on the lifting seat 221. The clamping drive unit 2123 can adopt a structure such as a motor + lead screw, cylinder, hydraulic cylinder or electric rod.
[0051] The film cutting module 213 of this embodiment includes a hot cutting component disposed between the film clamping module 212 and the turntable 111, and a cutting drive structure that drives the hot cutting component to reciprocate in the vertical direction. In this embodiment, the film is hot-cut by the hot cutting component, making the film easier to break.
[0052] Among them, such as Figure 2 and Figure 3As shown, the hot-cutting component in this embodiment is a heating wire 2131. The cutting drive structure includes two lifting blocks 2132 arranged laterally and two cutting drive units 2133 that drive the two lifting blocks 2132 to move synchronously. The two ends of the heating wire 2131 are respectively connected to the two lifting blocks 2132. In this embodiment, the two lifting blocks 2132 are slidably mounted on the lifting seat 221. The cutting drive unit 2133 can adopt a structure such as a motor + lead screw, a cylinder, a hydraulic cylinder, or an electric rod.
[0053] When wrapping the film, it is best to align the center of the pallet with the rotation center of the turntable 111. This ensures that the goods will not shift during rotation. Figure 1 and Figure 4 As shown, the turntable 111 of this embodiment has a plurality of positioning grooves 1111 distributed on its surface. The plurality of positioning grooves 1111 are used to position and cooperate with the plurality of support legs at the bottom of the tray so that the center of the tray is coaxially set with the rotation center of the turntable 111.
[0054] In addition, to facilitate pallet transport by forklifts, the turntable 111 is provided with two parallel sliding grooves 1112, one end of which extends to the side of the turntable 111 and has an open slot. The forklift's two forks can be inserted into the bottom of the pallet along the two sliding grooves 1112, and then the pallet can be lifted and dragged out.
[0055] Furthermore, such as Figure 1 As shown, the pallet rotating mechanism 110 also includes a ramp 114 located on the outer periphery of the turntable 111. The upper end of the ramp 114 is connected to two slots to facilitate the entry and exit of forklifts.
[0056] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
