Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, and in particular to a film wrapping packaging device. Background Technology

[0002] Cardboard boxes are a widely used packaging product. After production, multiple stacked boxes need to be packaged using a packing machine to form a neat unit, facilitating stacking, storage, and transportation. Existing packing equipment, such as the Chinese patent application No. 202510420863.2 entitled "A Packaging Device for Precast Cement Boards," mainly consists of a gantry frame, a first conveyor belt at both ends of the gantry frame, a rotating ring with a toothed ring rotatably connected to the gantry frame, a drive gear and a rotary motor on the gantry frame to drive the rotating ring, and a stretch film transverse bar on the gantry frame. During packing, the goods are placed in the rotating ring, which rotates and drives the stretch film transverse bar to rotate around the goods, thus wrapping and binding the goods with the stretch film. Although this technical solution can achieve the wrapping function and meets packaging needs to a certain extent, it still has some shortcomings in practical applications: First, the swivel ring and drive gear are completely exposed and lack necessary protective measures. Dust and debris can easily accumulate at the meshing part of the gear ring and drive gear, causing the transmission system to jam and run unstablely, which seriously affects the service life of the equipment and the packaging quality.

[0003] Secondly, the rotating ring and drive gear are completely exposed in the operating space without any safety protection structure. Personnel are likely to come into contact with the moving parts when passing by or operating them, posing a high risk of mechanical injury and making the safety hazard very prominent.

[0004] Third, the packaging equipment is specially equipped with a conveyor belt, which makes its overall size large. It is not convenient to move flexibly between different packaging stations, making it difficult to adapt to temporary packaging needs under various site conditions. It is also difficult to load and transport the assembled machine, which limits its application scope and practicality.

[0005] Therefore, given the aforementioned shortcomings and deficiencies of existing packaging equipment, there is an urgent need for a wrapping packaging device that has good dustproof performance, safe and reliable operation, and is compact and easy to move. Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned problems and shortcomings and provide an improved film wrapping and packaging device. This improved film wrapping and packaging device, through the built-in hidden design of the packaging film wrapping mechanism, can effectively isolate the intrusion of dust, fibers and other debris, ensuring the long-term stable and smooth operation of the equipment. It can also isolate the gear ring and drive gear assembly from the personnel working area, greatly reducing safety risks. Moreover, the overall size is smaller, which makes it easy to move flexibly between different packaging stations. It can adapt to the temporary packaging needs under various site conditions, and can also be loaded and transported as a whole machine. At the same time, by wrapping and packaging with packaging film rolls, it can prevent the edges of the carton from being dented, deformed or broken, effectively ensuring the integrity of the carton and the quality of the shipment.

[0007] The technical solution of this utility model is implemented as follows: an improved film wrapping device, characterized in that it includes a housing composed of a working platform and a gantry frame, and a wrapping and packaging working opening is formed between the gantry frame and the working platform; a packaging film wrapping mechanism is hidden and installed inside the working platform and the gantry frame; the packaging film wrapping mechanism consists of a toothed ring arranged around the wrapping and packaging working opening and rotatable, a packaging film roll fixed on the toothed ring, and a drive gear assembly for driving the toothed ring to rotate.

[0008] Preferably, the gantry frame is also provided with an openable door for easy replacement of the packaging film roll.

[0009] Preferably, one side of the door is hinged to the gantry frame, and the other side of the door is provided with a magnetic block that can attract each other to achieve closure.

[0010] Preferably, the present invention further includes a clamping and positioning assembly disposed on the gantry frame; the clamping and positioning assembly includes an electric telescopic rod and a pressure plate disposed on the movable end of the electric telescopic rod, the electric telescopic rod driving the pressure plate to move closer to or away from the work platform.

[0011] Preferably, the working platform consists of a front workbench and a rear workbench fixedly connected together, and a first accommodating space with an open top is formed between the front workbench and the rear workbench. The gantry frame includes a front gantry frame and a rear gantry frame fixedly connected together, and a second accommodating space with an open bottom is formed between the front gantry frame and the rear gantry frame. The second accommodating space is connected to the first accommodating space and together form an accommodating chamber for the installation and accommodation of the packaging film winding mechanism. The wrapping and packaging working port is arranged to penetrate through the second accommodating space.

[0012] Preferably, the receiving chamber is further provided with a plurality of limiting rollers arranged in a ring, the limiting rollers having an annular groove, and the inner ring edge of the toothed ring abutting against the bottom of the annular groove.

[0013] Preferably, a mounting slot is provided on the front or rear worktable located on the top of the first accommodating space, and a packaging film cutting assembly is provided in the mounting slot; the packaging film cutting assembly includes a mounting base, a cutting blade, and a swing drive motor. The mounting base is disposed in the mounting slot, one end of the cutting blade is hinged to the mounting base, and the other end of the cutting blade is driven by the swing drive motor to swing out into the first accommodating space or swing back into the mounting slot.

[0014] Preferably, the cutting blade includes a swing arm with one end hinged to the mounting base and a blade fixed to the swing arm; a smoothing silicone sheet fixed to the swing arm is provided on one side of the blade, and a smoothing swing arm with a silicone strip is provided on the other side of the blade with one end hinged to the mounting base. The hinge of the smoothing swing arm and the hinge of the swing arm are coaxially arranged so that the smoothing swing arm is driven by the swing drive motor to swing together.

[0015] Preferably, the drive gear assembly includes a drive motor and a gear disposed on the movable end of the drive motor, the gear meshing with a ring gear; the drive motor is a servo motor.

[0016] Preferably, the bottom of the work platform is also provided with multiple casters.

[0017] The beneficial effects of this utility model are as follows: The film-wrapping packaging device of this utility model conceals the film-wrapping mechanism within the work platform and gantry frame. This built-in concealed design effectively isolates the intrusion of dust, fibers, and other debris, preventing transmission jamming and wear between the gear ring and drive gear assembly due to dirt accumulation. This ensures long-term stable and smooth operation of the equipment, extends the service life of the film-wrapping packaging device, and ensures packaging quality. Furthermore, this built-in concealed design isolates the gear ring and drive gear assembly from the personnel working area. This design fundamentally eliminates the safety risk of accidental contact between personnel and the gear ring and drive gear assembly during packaging operations, effectively reducing mechanical injury hazards and creating a safer working environment in the workshop. Simultaneously, the film-wrapping packaging device of this utility model eliminates the conveyor structure, resulting in a smaller overall size and easier movement between different packaging stations. It can adapt to temporary packaging needs under various site conditions and can be transported as a complete unit, greatly improving its application range and practicality. In addition, wrapping film rolls are used to bind multiple stacked cartons. They have excellent elastic memory function and their tightening force is a uniformly distributed planar pressure. Unlike existing packing straps, they do not cause problems such as the edges of the cartons being dented, deformed or torn, effectively ensuring the integrity of the cartons and the quality of the shipment.

[0023] Figure 6 This is a schematic diagram of the usage state of this utility model. Detailed Implementation

[0024] like Figure 1 and Figure 3 As shown, the improved film wrapping device of this utility model includes a housing 10 consisting of a working platform 1 and a gantry frame 2 mounted on top of the working platform 1, with a wrapping opening 100 formed between the gantry frame 2 and the working platform 1; a packaging film winding mechanism 3 hidden inside the working platform 1 and the gantry frame 2; the packaging film winding mechanism 3 consists of a rotatable toothed ring 31 arranged around the wrapping opening 100, a packaging film roll 32 fixed on the toothed ring 31, and a drive gear assembly 33 for driving the toothed ring 31 to rotate. Specifically, the area formed in the inner diameter of the toothed ring 31 is larger than the area formed in the wrapping opening 100, so that the toothed ring 31 is arranged around the wrapping opening 100.

[0025] To facilitate the replacement of packaging film roll 32, such as Figure 2 As shown, the gantry frame 2 is also equipped with an openable door 4 for easy replacement of the packaging film roll 32.

[0026] To make opening and closing door 4 more convenient, no key is needed, such as Figure 2 As shown, one side of the door body 4 is hinged to the gantry frame 2, and the other side of the door body 4 is provided with a magnetic block 41 that can attract each other to achieve closure. In practical applications, one magnetic block 41 can be set on the other side of the door body 4 and on the gantry frame 2 respectively (i.e., a total of two magnetic blocks 41), or only one magnetic block 41 can be fixedly set on the other side of the door body 4 or on the gantry frame 2. When only one magnetic block 41 is used, the door body 4 or the gantry frame 2 is made of metal iron.

[0027] During the wrapping and packing of cardboard boxes, to prevent multiple boxes from swinging around and to ensure the packing is tight, such as... Figure 1 and Figure 2 As shown, this utility model also includes a clamping and positioning assembly 5 disposed on the gantry frame 2; the clamping and positioning assembly 5 includes an electric telescopic rod 51 and a pressure plate 52 disposed on the movable end of the electric telescopic rod 51, the electric telescopic rod 51 driving the pressure plate 52 to move closer to or away from the work platform 1. This allows the pressure plate 52 to apply pressure to limit the displacement of the carton, making the wrapping and packaging of the carton more reliable. In practical applications, the electric telescopic rod 51 can be a screw-type electric telescopic rod or an electric telescopic cylinder. Preferably, this utility model uses an electric telescopic cylinder, which has a faster movement speed and is suitable for high-speed reciprocating motion.

[0028] To further improve the structure of the work platform 1 and the gantry frame 2, making its structure simpler, easier to manufacture, and easier to accommodate the packaging film winding mechanism 3, such as... Figure 1 and Figure 4 As shown, the working platform 1 consists of a front workbench 11 and a rear workbench 12 fixedly connected together. A first accommodating space 13 with an open top is formed between the front workbench 11 and the rear workbench 12. The gantry frame 2 includes a front gantry frame 21 and a rear gantry frame 22 fixedly connected together. A second accommodating space 23 with an open bottom is formed between the front gantry frame 21 and the rear gantry frame 22. The second accommodating space 23 is connected to the first accommodating space 13 and together forms an accommodating chamber 200 for the packaging film winding mechanism 3 to be installed and accommodated. The wrapping and packaging working opening 100 is arranged through the second accommodating space 23. Specifically, the door 4 is set on the front gantry frame 21.

[0029] To facilitate the installation of the gear ring 31, prevent it from loosening and falling off, and allow it to rotate, such as... Figure 3 As shown, the receiving chamber 200 is also provided with a plurality of limiting rollers 6 arranged in a ring. Each limiting roller 6 has an annular groove 61, and the inner edge of the toothed ring 31 abuts against the bottom of the annular groove 61. By providing the annular groove 61, the toothed ring 31 can be prevented from loosening and falling off. Specifically, the axial direction of the limiting roller 6 is the same as the axial direction of the toothed ring 31.

[0030] like Figure 6 As shown, in practical applications, after the cardboard box is wrapped and packed, the packaging film roll 32 can be manually cut using scissors or other cutting tools. To simplify the packing operation, reduce the workload for workers, and improve packing efficiency, for example... Figure 3 and Figure 5As shown, a mounting slot 131 is provided on the front worktable 11 or rear worktable 12 located on the top of the first receiving space 13. A packaging film cutting assembly 7 is provided in the mounting slot 131. The packaging film cutting assembly 7 includes a mounting base 71, a cutting blade 72, and a swing drive motor 73. The mounting base 71 is disposed in the mounting slot 131. One end of the cutting blade 72 is hinged to the mounting base 71, and the other end of the cutting blade 72 is driven by the swing drive motor 73 to swing out into the first receiving space 13 or swing back into the mounting slot 131. Through the swing design of the cutting blade 72 and the setting of the mounting slot 131, the cutting blade 72 will not affect the wrapping movement of the packaging film when wrapping and packing cartons. After wrapping, the cutting blade 72 can extend to cut the packaging film. This structural design is very practical and reliable. In practical applications, the simplest drive connection method is to directly fix the hinge point between the cutting blade 72 and the mounting base 71 to the power output end of the swing drive motor 73. In practical applications, a reduction mechanism can be provided between the cutting blade 72 and the oscillating drive motor 73. By providing a reduction mechanism, noise and vibration during cutting can be reduced. This reduction mechanism can be a reduction gearbox or a reduction structure consisting of large and small pulleys plus a belt. These two reduction mechanisms are common knowledge, and their specific working principles will not be elaborated here. To allow the packaging film cutting assembly 7 to be hidden deeper in the mounting slot 131 and to further prevent obstruction of the wrapping movement of the packaging film, a slide rail assembly is also provided in the mounting slot 131, which is arranged towards the first receiving space 13. The slide rail assembly includes a slide rail, a slider slidably mounted on the slide rail, and an electric push rod that pushes the slider to slide back and forth. The mounting base 71 is fixed on the slider.

[0031] To ensure that the cutting blade 72 cuts the packaging film more smoothly and reliably, such as Figure 5 As shown, the cutting blade 72 includes a swing arm 721 hinged to a mounting base 71 at one end and a blade 722 fixed to the swing arm 721. A smoothing silicone sheet 74 fixed to the swing arm 721 is provided on one side of the blade 722, and a smoothing swing arm 75 with a silicone strip 751 is provided on the other side of the blade 722, with one end hinged to the mounting base 71. The hinge point of the smoothing swing arm 75 is coaxial with the hinge point of the swing arm 721, so that the smoothing swing arm 75 is driven by the swing drive motor 73 to swing. By providing the smoothing silicone sheet 74 and the smoothing swing arm 75 on both sides of the blade 722, the blade can smooth and straighten the packaging film when cutting it, making the cutting of the packaging film by the blade 722 more reliable and preventing incomplete cuts. In practical applications, the blade 722 uses a serrated blade. This makes cutting the packaging film easier.

[0032] To further improve the structure of the drive gear assembly 33, making it simple, easy to implement, and conducive to manufacturing, such as... Figure 4 As shown, the drive gear assembly 33 includes a drive motor 331 and a gear 332 disposed on the movable end of the drive motor 331, the gear 332 meshing with the gear ring 31. Specifically, the gear 332 is located in the first receiving space 13, and the drive motor 331 is located in the rear worktable 12. This design makes it difficult for workers to touch the meshing point of the gear 332 and the gear ring 31, ensuring operational safety. To enable the gear 332 to rotate at a higher speed, thereby increasing the rotational speed of the gear ring 31, the drive motor 331 is a servo motor.

[0033] To facilitate the movement of the entire film wrapping and packaging device, such as Figure 1 As shown, the bottom of the work platform 1 is also provided with multiple casters 8.

[0034] For convenient storage of items such as packaging film rolls 32, such as Figure 4 As shown, the front workbench 11 or the rear workbench 12 is also provided with a storage space 111 with an entrance and exit. In practical applications, the packaging film roll 32 is an existing transparent winding film, also known as a stretch film.
