DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the following embodiments are combined with the accompanying drawings to specifically illustrate the technical solutions of the present invention.

[0024] <Example>

[0025] See also Figures 1 to 3 The embodiment of the present invention provides a parallel unwinding device, comprising a base frame 2, on which at least two groups of unwinding units 1 are fixed and arranged side by side, and two unwinding units 1 constitute a group of unwinding units 1. An adjustable foot 3 is installed below the base frame 2.

[0026] In this embodiment, two groups of four unwinding units 1 are arranged side by side, but this is not limiting. In other embodiments, other numbers of unwinding units 1 may be provided, for example, six or eight unwinding units 1 may be arranged side by side.

[0027] See also Figure 3 and Figure 4 The unwinding unit 1 includes a base 13, a motor 14, a front wheel mechanism 16, a rear wheel mechanism 18, a turntable 11, a first synchronous pulley 15, a second synchronous pulley 20, and a synchronous belt 17.

[0028] The base 13 is a hollow structure. The cross-section of the base 13 is trapezoidal, with a large bottom area and a small top area. Such a structure has good stability.

[0029] The front wheel mechanism 16 and the rear wheel mechanism 18 are installed inside the base 13. The front wheel mechanism 16 and the rear wheel mechanism 18 have the same structure. Figure 6 , both include a connecting shaft 21 and two wheel bodies 22 fixed at both ends of the connecting shaft 21. A protruding structure 211 for mounting a synchronous pulley is provided in the middle of the connecting shaft 21. The wheel body 22 is provided with a groove along the wheel surface.

[0030] See also Figure 3 and Figure 4 The motor 14 is fixed to the side of the base 13, and the output end of the motor 14 is connected to the front wheel mechanism 16 to drive the front wheel mechanism 16 to rotate. In this embodiment, the motor 14 adopts a turbine motor 14.

[0031] See also Figure 3 and Figure 5 The first synchronous pulley 15 is mounted on the synchronous pulley mounting structure of the front wheel mechanism 16, and the second synchronous pulley 20 is mounted on the synchronous pulley mounting structure of the rear wheel mechanism 18. The first synchronous pulley 15 and the second synchronous pulley 20 are connected by a synchronous belt 17. The rotation of the front wheel mechanism 16 drives the synchronous belt 17 to rotate, thereby driving the rear wheel mechanism 18 to rotate.

[0032] The turntable 11 is mounted on the front wheel mechanism 16 and the rear wheel mechanism 18. The turntable 11 comprises two circular plates 111 and a winding shaft 112 connecting the two circular plates 111. One of the circular plates 111 is mounted to the left wheel 22 of the front wheel mechanism 16 and the rear wheel mechanism 18, while the other circular plate 111 is mounted to the right wheel 22 of the front wheel mechanism 16 and the rear wheel mechanism 18. The circular plates 111 fit into grooves in the grooves. The turntable 11 is driven by the front wheel mechanism 16 and the rear wheel mechanism 18.

[0033] The film strip 6 is wound on the winding shaft 112 of the turntable 11 . Figure 4 The guide shafts 5 and 6 shown are mounted on corresponding frames of the production line and are used to change the unwinding direction of the film strip 6 according to unwinding requirements. The guide shafts 5 and 6 are existing components of the production line and are not modified in this embodiment. Because the film strip material has a certain weight and the turntable itself is also relatively heavy, the turntable is placed in the grooves of the front wheel mechanism 16 and the rear wheel mechanism 18, and the unwinding operation is achieved smoothly by the action of gravity and friction.

[0034] See also Figure 1 and Figure 2 In this embodiment of the side-by-side unwinding device, each unwinding unit 1 is provided with a guide baffle 12 on either side. The left and right guide baffles 12 are symmetrically arranged to form a guide groove, with the width of the guide groove at the entrance being wider than at the rear. An opening is provided at the rear of the guide baffle 12, with two guide rollers 19 mounted at the opening. When placing the turntable loaded with film web material, manual operation may cause it to collide with the left or right side during placement. The guide groove formed by the two guide baffles 12 and the guide rollers 19 provide guidance, facilitating a smoother placement process.

[0035] The connection methods adopted between the various components in this embodiment are conventional connection methods such as bolt connection, welding, plug-in connection, and socket connection adopted according to actual conditions, so they will not be described in detail one by one.

[0036] The working principle of the parallel winding device of the embodiment of the utility model is as follows:

[0037] Motor 14 drives front wheel mechanism 16, which in turn drives rear wheel mechanism 18. The rotation of front wheel mechanism 17 and rear wheel mechanism 18 drives turntable 11, continuously transporting the film web to the next workstation. Two unwinding units form a group, with one unit active during operation. When one unit's film web runs out, the other unit's web can be immediately connected to the packaging machine production line, saving reloading time. This embodiment's parallel unwinding device has four side-by-side unwinding units, allowing it to simultaneously serve two packaging machine workstations, significantly improving efficiency.

[0038] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to fall within the scope of protection of the present invention.
