The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0031] The rapid film-forming process of the product based on PET film includes the following steps:

[0032] A. Preparation: Select the corresponding conveying roller according to the properties of the PET film to be processed;

[0033] B. Conveying: The PET film to be processed moves smoothly under the action of the conveying roller;

[0034] C. Film forming: The transported PET film is clamped by the clamping assembly, and the clamping assembly drives the PET film to continue to move. There is a film forming assembly adjacent to the clamping assembly. After the clamping assembly delivers the PET film into the film forming assembly, the clamping assembly withdraws from the film forming assembly. After the clamping assembly withdraws, the film forming assembly operates, and the semi-finished PET film is processed by the film forming assembly to obtain a finished PET film.

[0035] In the step C, both the clamping assembly and the film forming assembly are movable.

[0036] like Figure 1 and Figure 2As shown, the rapid film-forming device for products based on PET film includes a frame 1, and also includes a conveying roller 2, a driving component, a clamping component and a film-forming component. The conveying roller 2, the clamping component and the film-forming component are arranged adjacent to each other from front to back and are connected to the frame 1. The driving component is located between the frame 1 and the conveying roller 2 and the driving component can drive the conveying roller 2 to rotate continuously. The clamping component can clamp the PET film output from the conveying roller 2, and the clamping component can drive the clamped PET film to enter the film-forming component, and the film-forming component can feed the PET film therein for processing and forming.

[0037] In this rapid film-forming device for products based on PET film, the conveying roller is used to continuously convey the PET film to the clamping component, the clamping component clamps the conveyed PET film, and brings the clamped PET film into the film-forming component, and under the action of the film-forming component, the PET film at the clamping component is stably film-formed.

[0038] The driving assembly includes a bracket 3, a transmission shaft 4 and a fixed seat 5. The bracket 3 is fixedly connected to the upper part of the frame 1. The transmission shaft 4 is arranged horizontally and the transmission shaft 4 is axially fixedly connected to the upper part of the bracket 3. The outer end of the transmission shaft 4 extends out of the frame 1 and the outer end of the transmission shaft 4 is used to connect with the driving member. The fixed seat 5 is fixedly connected to the transmission shaft 4. The bracket 1, the transmission shaft 4 and the fixed seat 5 form a support unit. The number of the support units is two and the two support units are symmetrically arranged on both sides of the frame 1. The two ends of the conveying roller 2 are respectively connected to the corresponding support units.

[0039] The transmission shaft 4 rotates continuously under the action of the driving member. Since the conveying roller 2 is positioned between the two fixing seats 5, and the fixing seats 5 are connected to the transmission shaft 4, the above structure finally stably positions and connects the conveying roller 2 between the two supporting units.

[0040] The fixing seat 5 includes a cylindrical connecting tube 5a and a disc-shaped connecting disk 5b. The side of the connecting tube 5a has a through deformation notch 5a1 along its axial direction. The side of the connecting tube 5a is also connected with a fastener. The connecting tube 5a is sleeved on the transmission shaft 4 and the two are fixedly connected. The conveying roller 2 is pressed tightly between the two connecting disks 5b.

[0041] After the fastener locks the deformation notch 5a1, the connecting tube 5a can be sleeved on the connecting shaft 4 to form a stable fixed connection.

[0042] The fasteners are common parts such as existing screws or bolts.

[0043] The connection plate 5 b has a recessed positioning notch 5 b 1 , and the end of the conveying roller 2 matches the positioning notch 5 b 1 and is embedded in the positioning notch 5 b 1 .

[0044] The positioning recess 5b1 enables a stable positioning connection between the conveying roller 2 and the connecting plate 5b.

[0045] The clamping assembly includes a base 6, an upper clamping plate 7, a lower clamping plate 8, a cylinder 9 and a motor 10. The frame 1 is provided with a guide rail 1a. The base 6 is connected to the guide rail 1a. The upper clamping plate 7 and the lower clamping plate 8 are both connected to the base 6. The cylinder 9 is fixedly connected to the base 6 and the piston rod of the cylinder 9 is fixedly connected to the upper clamping plate 7. The motor 10 is fixedly connected to the frame 1 and the motor 10 is connected to the base 6.

[0046] The lower clamping plate 8 is fixed on the base 6, and the upper clamping plate 7 is located on the upper part of the lower clamping plate 8. The cylinder 9 drives the upper clamping plate 7 to move up and down to stably clamp or release the PET film.

[0047] Finally, the PET film is clamped or released stably.

[0048] The side of the base 6 is fixedly connected with a guide cylinder 11, the frame 1 is provided with a screw rod 12 which is transversely arranged and axially fixed on the frame 1, the rotating shaft of the motor 10 is fixedly connected with the screw rod 12, the screw rod 12 is passed through the guide cylinder 11 and the two are threadedly connected.

[0049] It also includes a U-shaped cover shell 13 , both ends of the U-shape of the cover shell 13 are fixedly connected to the frame 1 , the screw rod 12 is located in the cover shell 13 and the screw rod 12 is axially fixedly connected to the side of the cover shell 13 , and the guide cylinder 11 is located in the cover shell 13 .

[0050] After the motor 10 drives the screw rod 12 to rotate, since the guide cylinder 11 is connected to the machine base 16, the guide cylinder 11 will not rotate with the screw rod 12. Therefore, the guide cylinder 11 will translate along the screw rod 12. Finally, the entire machine base 16 can translate on the frame 1.

[0051] The film forming assembly includes a machine base 14, a cylinder 15, a blade 16 and a blade 17. The machine base 14 is connected to the guide rail 1a, the blade 16 is fixedly connected to the machine base 14, the inner end of the blade 17 is hinged to the inner end of the blade 16, the cylinder body of the cylinder 15 is hinged to the machine base 14, and the piston rod of the cylinder 15 is hinged to the middle part of the blade 17.

[0052] Blade 16 is fixed on base 2 14, blade 17 is hinged on blade 16 and blade 17 is connected to cylinder 2 15, so cylinder 2 15 can drive blade 17 to swing relative to blade 16, finally realizing the cutting process of film forming operation.

[0053] It also includes a cylinder three 18, the cylinder body of the cylinder three 18 is fixedly connected to the frame 1, and the piston rod of the cylinder three 18 is fixedly connected to the base two 14.

[0054] Cylinder three 18 can drive the entire film forming assembly to translate stably along the guide rail.

[0055] In this rapid film-forming process for products based on PET film, the clamping component can stably pull the PET film at the conveying roller to the set position during operation, and the pulled PET film is quickly and stably film-formed through the film-forming component.

[0056] Since both the clamping assembly and the film-forming assembly can move, the PET film can be stably film-formed with relatively high stability.

[0057] At the same time, since the conveying roller, the traction assembly and the film forming assembly are arranged adjacent to each other, the entire device has a compact structure and has high practical value.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
