Description

Technical Field

[0001] This utility model relates to the technical field of composite film production equipment, specifically to a composite film feeding structure and its pressing device. Background Technology

[0002] In the composite film production process, the feeding structure is a key component to ensure the quality of composite film pressing. It is mainly used to support the raw material roller and realize the stable unwinding of the composite film, so as to provide a continuous and flat film material for subsequent pressing processes. In the prior art, such as the composite membrane pressing device with pressure detection function disclosed in Chinese patent CN220031224U, a raw material roller is provided on one side of the frame. The outer wall of the rotating shaft of the raw material roller is in close contact with the inner side of the V-shaped groove. By rotating the second bidirectional screw, the second bidirectional screw drives two clamping blocks to move relative to each other, so that the inner sides of the two V-shaped grooves clamp the outer wall of the rotating shaft of the raw material roller.

[0003] While this structure can fix the raw material roller, it has significant shortcomings in practical applications. Firstly, the raw material roller in this device is unpowered, and the unwinding of the composite film relies entirely on the traction of the subsequent pressing mechanism. This means that while the pressing mechanism completes the pressing action, it also needs to transport the composite film. This "passive unwinding" method causes continuous dragging of the composite film on the raw material roller. Especially when the composite film is thin, soft, or tension-sensitive, it easily leads to tensile deformation during unwinding, affecting the flatness, dimensional accuracy, and interlayer adhesion strength of the final product. Secondly, the structure that adjusts the raw material roller clamping using V-grooves and bidirectional screws has poor operational flexibility. For raw material rollers of different lengths, the clamping block position needs repeated adjustments to adapt. Furthermore, the clamping stability is easily affected by factors such as V-groove wear and screw loosening, making it difficult to guarantee the coaxiality of the raw material roller during rotation, further exacerbating the instability of the composite film unwinding.

[0004] Therefore, there is an urgent need to propose a composite membrane feeding structure and a composite membrane pressing device to solve the above problems. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a composite film feeding structure and its pressing device to solve the problems of composite film stretching deformation and inconvenient adjustment caused by passive unwinding of raw material rollers in the prior art.

[0006] To achieve the above objectives, this utility model provides a composite film feeding structure, including a base, a left mounting frame and a right mounting frame arranged along the length of the base, and a raw material roller installed between the left mounting frame and the right mounting frame. A rotary driver, mounted on the right mounting bracket, is used to drive the raw material roller to rotate; A linear actuator, mounted on a base, is used to drive the left mounting bracket to move towards or away from the right mounting bracket.

[0007] Preferably, the left mounting bracket includes a first frame and a first bearing seat fixed on the first frame; The first chuck is rotatably connected to the first bearing housing via a connecting shaft.

[0019] like Figure 1 and Figure 2 As shown, the composite film feeding structure of this utility model includes a base 1, which extends along its length and serves as the mounting base for the entire structure.

[0021] The right mounting frame 3 includes a second frame 31, on which a second bearing seat 32 is fixedly mounted, and a bearing is also installed inside the second bearing seat 32; the second chuck 33 is rotatably connected to the second bearing seat 32 via a connecting shaft, and the connection method is similar to that of the first chuck 23 of the left mounting frame 2, and is used to clamp the other end of the raw material roller 6 and rotate synchronously with the raw material roller 6.

[0022] like Figure 2 and Figure 3 As shown, a rotary driver 4 is installed on the right mounting frame 3 to achieve active rotation of the raw material roller 6. The rotary driver 4 includes a geared motor 41 and a third bearing housing 42, both of which are fixed on the second frame 31. A bearing is installed inside the third bearing housing 42, and a drive shaft 43 passes through the bearing, allowing it to rotate relative to the third bearing housing 42.
