[0026] The two groups of clamping arms 4 and the fixed shell 3 are movably connected through a first transmission shaft 5, a movable limiting sleeve rod 6 is movably connected to the outer side of the first transmission shaft 5, a second transmission shaft 7 located below the first transmission shaft 5 is movably connected inside the fixed shell 3, and a conveying roller shaft 8 is fixed to the outer side of the second transmission shaft 7, and the first transmission shaft 5 and the second transmission shaft 7 are connected through a first transmission belt 9;

[0027] The ends of the two groups of clamping arms 4 are movably connected with hot pressing rollers 16, and the hot pressing rollers 16 and the clamping arms 4 are movably connected through connecting shafts 15, and multiple groups of electric heating wires are distributed inside the hot pressing rollers 16, and electric slip rings 17 are arranged at the inner ends of the two groups of connecting shafts 15. A control module 19 is fixed at the top end of the fixed shell 3, and the control module 19 and the two groups of electric slip rings 17 are electrically connected through wires 18;

[0028] The storage belt 2 is transported inside the main body 1 by multiple groups of conveying wheels 11, wherein two groups of clamping arms 4 drive the hot pressing rollers 16 to press the edge positions of the protective film 21 and the storage belt 2 against each other for plastic sealing. Furthermore, the clamping arms 4 and the fixed shell 3 are elastically connected by a torsion spring frame 14, thereby maintaining the clamping force of the clamping arms 4 on the protective film 21 and the storage belt 2;

[0029] The conveying wheel 11 rotates to drive the first transmission shaft 5 to rotate through the second transmission belt 13, and the first transmission shaft 5 and the second transmission shaft 7 are mutually driven through the first transmission belt 9, so that the conveying roller 8 can synchronously drive the protective film 21 to perform the unwinding operation;

[0030] That is to say, during the conveying process of the storage belt 2, the protective film 21 is actively unwound synchronously and cooperates with the storage belt 2, which effectively avoids the situation where the protective film 21 is deformed due to the passive unwinding of the protective film 21. The overall plastic sealing effect of the protective film 21 is better and the use is more convenient.

[0031] Conveying wheels 11 are rotatably connected at the top and bottom of both ends of the fixed shell 3. Each set of conveying wheels 11 is movably connected to the fixed shell 3 through a driving shaft 10. Both ends of one set of driving shafts 10 and the first transmission shaft 5 are connected through a second transmission belt 13. Transmission gears 12 meshing with each other are fixed on the outside of the two sets of driving shafts 10. The outside of one set of driving shafts 10 is fixedly connected to an external driving motor.

[0032] A guide shaft 20 is movably connected to the top of the fixed shell 3, and a protective film 21 is movably connected to the top of the fixed shell 3, and the end of the protective film 21 is sequentially attached to the surface of the storage belt 2 along the guide shaft 20, the movable limiting sleeve rod 6, the conveying roller shaft 8 and the hot pressing roller 16.

[0033] See also Figure 5 and Figure 6 The two ends of the interior of the fixed shell 3 and the two sets of clamping arms 4 are fixedly connected by a torsion spring frame 14, and the torsion spring frame 14 is located outside the first transmission shaft 5. The present invention sets the above structure, where under the action of the torsion spring frame 14, the hot pressing roller 16 can always press the protective film 21 against the surface of the storage belt 2, so as to better perform the plastic sealing operation.

[0034] The working principle of the present invention is as follows: when in use, the power is turned on, and the top and bottom of both ends of the main body 1 are movably connected with conveying wheels 11, and then the two sets of conveying wheels 11 can rotate synchronously in opposite directions under the cooperation of two sets of mutually meshing gears, thereby conveying the storage belt 2;

[0035] During the conveying process of the storage belt 2, the products are placed in the placement cavity inside the storage belt 2 in sequence through the cooperation of the external vibration plate feeding equipment and the mechanical arm, and then the storage belt 2 carries the products for moving conveyance;

[0036] The storage belt 2 is transported inside the main body 1 by multiple groups of conveying wheels 11, wherein two groups of clamping arms 4 drive the hot pressing rollers 16 to press the edge positions of the protective film 21 and the storage belt 2 against each other for plastic sealing. Furthermore, the clamping arms 4 and the fixed shell 3 are elastically connected by a torsion spring frame 14, thereby maintaining the clamping force of the clamping arms 4 on the protective film 21 and the storage belt 2;

[0037] The conveying wheel 11 rotates to drive the first transmission shaft 5 to rotate through the second transmission belt 13, and the first transmission shaft 5 and the second transmission shaft 7 are mutually driven through the first transmission belt 9, so that the conveying roller 8 can synchronously drive the protective film 21 to perform the unwinding operation;

[0038] That is to say, during the conveying process of the storage belt 2, the protective film 21 is actively unwound synchronously and cooperates with the storage belt 2, which effectively avoids the situation where the protective film 21 is deformed due to the passive unwinding of the protective film 21. The overall plastic sealing effect of the protective film 21 is better and the use is more convenient.

[0039] Furthermore, electric heating wires are distributed inside the two sets of hot pressing rollers 16, which can generate heat for the hot pressing rollers 16 to perform plastic sealing on the protective film 21. At the same time, electric slip rings 17 are provided at the inner ends of the hot pressing rollers 16. When the hot pressing rollers 16 passively perform heat plastic sealing on the protective film 21, the electric slip rings 17 will not affect the transmission of electrical signals between the control module 19 and the two sets of hot pressing rollers 16.
