DETAILED DESCRIPTION

[0026] The embodiment of the present invention provides a device for slowly stretching and stretching a decorative film, such as Figure 1-6 As shown, it includes a base plate 1, with a receiving plate 2 located directly above the base plate 1. The base plate 1 is slidably fitted with four extension components 3, which correspond diagonally to the base plate 1. The upper ends of the extension components 3 pass through the receiving plate 2. The extension components 3 include a slide 31, a slide rod 33, a bracket 34, and a clamping rod 4, which is used to grasp the edges and corners of the membrane body.

[0027] The slide 31 slides in cooperation with the base plate 1, the slide rod 33 is vertically welded to the upper end of the slide 31, the slide rod 33 passes through the receiving plate 2, the middle section of the bracket 34 slides in cooperation with the rod body of the slide rod 33, the end of the clamping rod 4 is hinged to the end of the bracket 34, and the bracket 34 and the clamping rod 4 are both located above the receiving plate 2.

[0028] It also includes a thin electric push rod 5 and an elastic rope 8. Small springs 35 are welded on both sides of the upper and lower parts of the middle section of the bracket 34. The upper small spring 35 conflicts with the upper end of the slide rod 33, and the lower small spring 35 conflicts with the top of the slide seat 31. Figure 4 、 5 Shown, this state is not in operation.By small spring 35, bracket 34 is placed in the middle area of ​​slide bar 33.

[0029] One end of the elastic rope 8 is fixedly tied to the middle section of the bracket 34 , and one end of the elastic rope 8 is fixedly tied to the slide 31 . The thin electric push rod 5 is fixedly installed on the slide 31 . The movable end of the thin electric push rod 5 transversely passes through the slide 31 and contacts the elastic rope 8 .

[0030] The base plate 1 is provided with four slide grooves 11, which correspond to the diagonals of the base plate 1 one by one. The slide seat 31 slides in cooperation with the slide groove 11. A shaft rod 12 is connected to the central axis of the base plate 1, and a motor is connected to the end of the shaft rod 12. A vertical thick electric push rod 13 is provided under the base plate 1. The movable end of the thick electric push rod 13 passes through the shaft rod 12 and is connected to the bottom of the receiving plate 2.

[0031] A magnet 32 ​​is fixedly mounted on the side of the slide 31 near the center of the substrate 1, and an electromagnet module 7 is fixedly mounted on one end of the slide 11 near the center of the substrate 1. A large spring 6 is fixedly mounted between the magnet 32 ​​and the electromagnet module 7, and the magnetic pole on the side opposite to the electromagnet module 7 is the N pole.

[0032] During operation, the electromagnetic module 7 is energized to generate a magnetic field. By virtue of the principle of mutual repulsion between like magnetic poles, the slide 31 has the force of the electromagnetic module 7. The current intensity is then controlled to continuously increase the current intensity entering the electromagnetic module 7, thereby gradually increasing the magnetic field intensity, thereby achieving the effect of pushing the slide 31 away.

[0033] A slot 41 is provided on the body of the clamping rod 4, and clamping strips 42 are symmetrically hinged on both sides of the clamping rod 4 and the clamping rod 4. A screw hole is provided at the end of the clamping rod 4, and an insertion rod 341 is threaded through the end of the bracket 34. The insertion rod 341 is threadedly connected to the screw hole, and the movable end of the clamping strip 42 can be inserted into the slot 41.

[0034] Clamping method: The clamping rod 4 is wound around the corner of the decorative film, and the clamping rod 4 is locked by the insertion rod 341, and then the end of the clamping strip 42 is inserted into the card slot 41. After the clamping strip 42 and the card slot 41 are locked, the corner of the decorative film is clamped.

[0035] A tension sensor is fixedly mounted on one end of the electromagnet module 7 facing the magnet 32. The tension sensor is fixedly mounted with a buffer sponge pad. The tension sensor transmits the pulling force it receives to an external computer terminal, thereby controlling the four extension components 3 to move synchronously away from each other.

[0036] A positioning block 51 is fixedly mounted on the end of the thin electric push rod 5. The positioning block 51 is L-shaped. An elastic rubber 511 is fixedly mounted on the side of the positioning block 51 away from the thin electric push rod 5. The elastic rope 8 is in contact with the elastic rubber 511. Since the elastic rubber 511 is arc-shaped, the elastic rope will break away from the elastic rubber 511 when it is stretched to its longest length.

[0037] An air blowing pipe 9 is provided at the rear of the base plate 1 . The air blowing pipe 9 is fixedly mounted to the bottom of the base plate 1 , and an air outlet of the air blowing pipe 9 faces the extension assembly 3 .

[0038] The receiving plate 2 is provided with a corresponding groove 21, which corresponds to the slide groove 11 one by one, and the slide rod 33 passes through the corresponding groove 21. The receiving plate 2 is used to hold the decorative film and play the role of receiving the decorative film.

[0039] Working Principle: Place the edge of the decorative film on the receiving plate 2 and secure it to the clamping rod 4. Power the electromagnet module 7 to generate a magnetic field, which pushes the slide 31 to move slowly, thereby slowly stretching the decorative film. When the slide 31 reaches its limit, the stretching is complete.

[0040] Next, the substrate 1 is flipped over so that it is vertical and the air outlet of the air blow pipe 9 is facing downward. The thick electric push rod 13 contracts to lower the receiving plate 2. At the same time, the thin electric push rod 5 extends, and the positioning block 51 contacts the elastic rope 8. The elastic rope 8 is stretched to its limit, causing the bracket 34 to approach the base 31, and the small spring 35 to deform.

[0041] When the elastic cord 8 is released from the elastic rubber 511, the bracket 34 oscillates back and forth. The thin electric push rod 5 contracts, causing the elastic cord 8 to once again contact the elastic rubber 511 of the positioning block 51. This process repeats, causing the bracket 34 to vibrate repeatedly. With the help of air from the air blower 9, the dust is shaken off.

[0042] In summary, the decorative film slow extension and stretching device comprises a base plate 1, a receiving plate 2, an extension assembly 3, a clamping rod 4, a thin electric push rod 5, an electromagnet module 7, and an elastic cord 8. The thin electric push rod 5 extends and stretches the elastic cord 8. When the elastic cord 8 detaches, the bracket 34 swings up and down, thereby driving the entire decorative film back and forth. This achieves the purpose of shaking off dust from the decorative film surface. This replaces traditional vacuuming methods and avoids the suction force that causes localized stretching and traction on the decorative film, which can lead to uneven thickness of the decorative film.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
