[0023] In this embodiment, the base 1 serves as the supporting foundation of the entire wrapping machine to ensure that the machine is stable and does not shake. The design of the rotating shaft 10 allows the film roller 7 to rotate flexibly, which is convenient for the winding operation of the packaging film. The bottom plate 3 serves as the supporting point at one end of the film roller 7 to ensure that the film roller 7 is stable and does not shake. The first electric telescopic rod 4 is connected to and controls the lifting and lowering of the mounting plate 5 through its output rod. This design makes the distance between the top plate 6 and the bottom plate 3 adjustable, which is convenient for adapting to film rollers 7 of different sizes and simplifies the installation and disassembly process of the film roller 7. The limit block is used to limit the axial movement of the film roller 7 to ensure that the film roller 7 does not fall off or shift during the winding process.

[0024] In a further preferred embodiment of the utility model, the support assembly includes a placement seat 11, a support tube 21 and a plurality of balls 22. The placement seat 11 is detachably mounted on the top of another of the rotating shafts 10 through a limiting tube and a limiting piece. The support tube 21 is fixed to the bottom of the placement seat 11. The plurality of balls 22 are all embedded in the bottom of the support tube 21, and the plurality of balls 22 are all in contact with the bottom inner wall of the support frame 2.

[0025] In this embodiment, the placement seat 11 serves as the installation base for the support cylinder 21 and the workpiece to be packaged. Its position is opposite to the base plate 3, and together they constitute the relative position relationship between the film roller 7 and the workpiece, ensuring the smooth progress of the winding operation. The design of the support cylinder 21 not only provides stable support for the workpiece, but also realizes rolling contact with the support frame 2 through the ball 22 at its bottom, thereby reducing the friction resistance of the workpiece during the winding process. The rolling characteristics of the ball 22 enable the workpiece to rotate easily during the winding process without the need for external force, thereby greatly improving the efficiency and uniformity of the winding. At the same time, the contact mode of the ball 22 also reduces wear and tear, thereby extending the service life of the equipment.

[0026] In a further preferred embodiment of the utility model, the power assembly includes two motors 12 and a plurality of bevel gears 13, the two motors 12 are fixed at the bottom of the support frame 2 and are located at the top of the base 1, the plurality of bevel gears 13 are respectively installed on the output shafts of the two motors 12 and the two rotating shafts 10, and the plurality of bevel gears 13 are meshed with each other.

[0027] In this embodiment, the motor 12 serves as a power source and is responsible for driving the rotation of the placement seat 11 and the film roller 7, thereby realizing automatic winding of the packaging film. The design of the bevel gear 13 realizes the power transmission between the output shaft of the motor 12 and the rotating shaft 10, and allows them to rotate on different axes, thereby adapting to the layout requirements of the rotating shaft 10 on the support frame 2.

[0028] In a further preferred embodiment of the utility model, a plurality of second electric telescopic rods 15 are fixed to the top of the support frame 2, and the same connecting plate 16 is fixed to the output rods of the plurality of second electric telescopic rods 15, and a plurality of springs 17 are installed at the bottom of the connecting plate 16, and the same resistance plate 18 is installed at the bottom of the plurality of springs 17, and an extrusion plate that can contact the surface of the workpiece is rotatably installed at the bottom of the resistance plate 18.

[0029] In this embodiment, the second electric telescopic rod 15 serves as a power source and can control the lifting and lowering of the connecting plate 16 and the components thereunder to adapt to workpieces of different heights or shapes. The connecting plate 16 serves as the installation base for the spring 17 and the contact plate 18 and can withstand the pressure from the workpiece. The elastic characteristics of the spring 17 enable the contact plate 18 to be adaptively adjusted according to the shape and size of the workpiece, ensuring that the extrusion plate is in close contact with the surface of the workpiece while reducing the impact and vibration caused by rigid contact. The extrusion plate is used to directly contact the surface of the workpiece.

The design of the trigger rod 20 enables the pressure sensor 19 to sense the contact pressure through the indirect action of the contact plate 18 without directly contacting the workpiece. Through the combined use of the pressure sensor 19 and the trigger rod 20, the structure can monitor and feedback the contact pressure information between the contact plate 18 and the workpiece in real time, thereby realizing intelligent control of the contact pressure.

[0032] In a further preferred embodiment of the utility model, electric guide rails 9 are installed on the top inner wall and the bottom inner wall of the support frame 2, and a heating wire 14 for cutting off the protective film is provided between the moving parts of the two electric guide rails 9.

In this embodiment, the moving part of the electric guide rail 9 is used to install and support the heating wire 14. The heating wire 14 is a resistance wire or electric heating element that can generate heat. When power is turned on, it will generate heat. When the protective film needs to be cut off, the control system will start the driving device of the electric guide rail 9, so that the moving part drives the heating wire 14 to move to the specified position along the preset path. Then, the control system will energize the heating wire 14 to make it heat up and melt the protective film, thereby realizing the cut-off function.

[0034] In a further preferred embodiment of the utility model, two limit shafts 8 are installed in the support frame 2, and the two limit shafts 8 are fixed with anti-slip sleeves on the outside. The limit shafts 8 are used to limit the extension direction of the protective film, and a rubber anti-slip pad is installed on the top of the placement seat 11.

[0035] In this embodiment, the limiting shaft 8 is used to limit the extension direction of the protective film (packaging film, wrapping film, etc.), avoiding the problem of uneven winding or winding failure caused by directional deviation. The anti-slip sleeve is usually made of a material with a certain friction coefficient, such as rubber, silicone, etc. Its function is to increase the friction between the limiting shaft 8 and the protective film to prevent the protective film from sliding out of the control of the limiting shaft 8 during the winding process. The rubber anti-slip pad is also made of a material with excellent anti-slip properties. Its function is to increase the friction between the workpiece and the placement seat 11 to prevent the workpiece from sliding or shifting due to vibration or external force during the winding process.

[0036] To sum up, compared with the related art, the device can adjust the heights of the mounting plate 5 and the connecting plate 16 respectively by setting the first electric telescopic rod 4 and the second electric telescopic rod 15, so that the device can stabilize film rollers 7 of different lengths and stabilize workpieces of different heights. The workpiece can be supported by setting a support assembly, and the film roller 7 and the placement seat 11 can be driven to rotate by the power assembly to realize the winding packaging of the workpiece. The protective film can be cut off by setting the electric guide rail 9 in combination with the heating wire 14. At the same time, the heating wire 14 is thinner, and it is easy to cool down quickly after the power is turned off, and the safety is higher.
