Description

Technical Field

[0001] The invention relates to the technical field of film winding, and in particular to an automatic graphene film winding device. Background Art

[0002] Graphene film is a two-dimensional material composed of a single layer of carbon atoms. It has extremely high electrical conductivity, thermal conductivity and mechanical strength, as well as excellent transparency and flexibility. It is widely used in transparent conductive layers in devices such as touch screens and displays. During the processing and production process, it needs to be rolled up into paper rolls for storage in a certain amount.

[0003] However, the following problems exist in the process of rolling up the graphene film: if the film is rolled up only by a rotating paper roll, wrinkles may easily appear on the film due to uneven tension and static electricity, and the wrinkled parts may become stress concentration points, accelerating the aging or damage of the material, thereby shortening the service life of the product. In addition, the wrinkles formed when the graphene film is rolled up may cause further damage or unevenness of the graphene film when it is unfolded again, making it difficult to restore the film to its original state, thus affecting the use effect.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] like Figure 1 As shown, a graphene film automatic winding device includes an equipment frame 10; a base plate 11 is fixedly installed on the equipment frame 10, two smoothing mechanisms 2 are symmetrically arranged at the upper end of the base plate 11, and a winding mechanism 3 is arranged on the right side of the two smoothing mechanisms 2.

[0035] like Figure 1 and Figure 2 As shown, the smoothing mechanism 2 includes a supporting plate 20, the supporting plate 20 is fixedly installed on the upper end of the base plate 11, and two upper and lower symmetrical guide rollers 21 are rotatably installed on the upper end of the base plate 11 and located on the left side of the supporting plate 20 through an axis plate, and a rolling portion 22 for tightening and rolling the film forward and backward is arranged above the supporting plate 20, and a driving portion 23 for driving the two rolling portions 22 is arranged on the base plate 11.

[0036] like Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the winding mechanism 3 includes a support plate 30, and two support plates 30 are fixedly installed on the upper end of the base plate 11, which are symmetrical with respect to the corresponding supporting plates 20. A discharge roller 31 is rotatably installed on the left side between the two support plates 30 and above the supporting plate 20 through a ratchet and pawl mechanism. A shaft column 32 located on the upper right side of the corresponding discharge roller 31 is also rotatably installed on the front support plate 30 through a ratchet and pawl mechanism. The rear end of the shaft column 32 passes through the corresponding support plate 30 and is hinged with a shaft rod 33. A U-shaped groove 34 cooperating with the shaft rod 33 is opened on the rear support plate 30, and balls are evenly rolled on the inner wall of the arc section of the U-shaped groove 34, and a limiting portion 35 is arranged in the U-shaped groove 34.

[0037] like Figure 1 and Figure 4 As shown, the rolling portion 22 is provided with a rotating portion 5 for driving the corresponding unwinding roller 31 to rotate, the shaft column 32 is provided with an adjusting portion 6 for adjusting the rotation angle of the shaft column 32 as the thickness of the winding film increases, and a linkage portion 8 is provided between the adjusting portion 6 and the rotating portion 5.

[0038] like Figure 4 and Figure 6 As shown, the limiting portion 35 includes a slide groove, and the arc section of the U-shaped groove 34 is symmetrically provided with a slide groove, and a fixed seat 350 is slidably installed in the slide groove through a No. 3 compression spring, and the opposite surfaces of the two fixed seats 350 are rotatably installed with limiting rollers 351.

[0039] During specific work, the external paper tube is manually fixed onto the shaft rod 33, and then the shaft rod 33 is rotated into the U-shaped groove 34 and contacts the limiting roller 351. As the shaft rod 33 moves, the corresponding fixing seat 350 will be pushed by the limiting roller 351 to slide into the corresponding slide groove and compress the No. 3 compression spring. After the end of the shaft rod 33 is in contact with the ball in the U-shaped groove 34, the fixing seat 350 pushes the limiting roller 351 to press the shaft rod 33 under the action of the corresponding No. 3 compression spring to limit the movement of the shaft rod 33. After that, the film is manually passed between the corresponding two guide rollers 21, and then passed through the rolling part 22 to bypass the bottom of the discharge roller 31 and fixed to the external paper tube installed on the shaft rod 33.

[0040] Afterwards, the driving unit 23 drives the two groups of rolling units 22 to move back and forth left and right, and the rolling units 22 tension and flatten the film. At the same time, the rotating unit 5 drives the shaft column 32 and the feed roller 31 to rotate, so that the feed roller 31 drives the film smoothed by the rolling unit 22 to move to the right, and at the same time drives the shaft rod 33 to rotate through the shaft column 32, so as to rewind the smoothed film driven by the feed roller 31, thereby ensuring the flatness of the rewound film, and adjusting the rotation angle of the shaft column 32 through the adjusting unit 6 to avoid the thickness of the film increasing when it is rolled up and affecting the pulling force on the film.

[0041] like Figure 1 , Figure 2 and Figure 4 As shown, the rolling portion 22 includes a base 220, and the bases 220 are fixedly installed at both ends of the support plate 20. The upper ends of the two bases 220 are slidably installed with a fixed plate 221 with an inverted structure. An ion wind rod 222 is fixedly installed between the two vertical sections of the fixed plate 221 through a support plate. Two roller shafts 223 are arranged on the upper and rear sides of the support plate 20. The two roller shafts 223 form a herringbone structure. The two roller shafts 223 are away from one end of the middle of the support plate 20. A slider 224 is fixedly installed, and two No. 1 guide pillars 225 are fixedly installed at the lower end of the slider 224 along the axial direction of the corresponding roller shaft 223. An inclined groove 226 is provided at a position corresponding to the No. 1 guide pillar 225 on the base 220. The opposite surfaces of the two vertical sections of the fixed plate 221 are both slidably installed with shaft seats 227, and a roller 228 is rotatably installed between the two shaft seats 227. A push-pull member 4 for pushing and pulling the roller 228 and the roller shaft 223 up and down is provided between the two rolling parts 22.

[0042] like Figure 1 and Figure 2As shown, the driving part 23 includes a connecting plate 230, which is fixedly installed between the two fixed plates 221, and a motor 231 is fixedly installed at the lower end of the base plate 11 and is located on the right side between the two fixed plates 221. The output shaft of the motor 231 rotates and passes through the base plate 11, and then a turntable 232 is fixedly installed thereon, and a driving rod 233 is eccentrically hinged on the turntable 232, and the other end of the driving rod 233 is hinged to the connecting plate 230.

[0043] like Figure 1 , Figure 2 and Figure 4 As shown, the push-pull member 4 includes an electric push rod 40, the upper end of the connecting plate 230 is fixedly installed with the electric push rod 40, the telescopic section of the electric push rod 40 is fixedly installed with a push-pull plate 41, the upper end of the shaft seat 227 slides through the corresponding fixed plate 221 and is fixedly connected to the lower end of the push-pull plate 41, and the lower end of the push-pull plate 41 and the slider 224 are both slidably installed with T-shaped slide bars 42 at positions corresponding to each other in a one-to-one manner. The upper end of the fixed plate 221 is provided with a No. 1 waist groove corresponding to the T-shaped slide bar 42, and the vertical section of the T-shaped slide bar 42 slides through the corresponding No. 1 waist groove and is fixedly connected to the corresponding slider 224.

[0044] During operation, the motor 231 drives the turntable 232 to rotate, and the turntable 232 drives the connecting plate 230 to move left and right through the driving rod 233, and the connecting plate 230 drives the two fixed plates 221 to move back and forth left and right. Before the fixed plate 221 moves to the left, the electric push rod 40 pulls the push-pull plate 41 downward, and the push-pull plate 41 drives the roller 223 to fit the film through the T-shaped slide bar 42 and the slider 224, and drives the roller 228 to fit the film through the shaft seat 227. After that, the fixed plate 221 moves left and The film is blown by the ion wind rod 222 to remove static electricity and reduce wrinkles caused by adhesion between the films and between the films and the support plate 20. The roller 223 is then driven to move left by the T-shaped slide bar 42 and the slider 224 to roll and smooth the film. During the movement of the roller 223, the No. 1 guide column 225 and the inclined groove 226 cooperate to make the roller 223 move leftward and toward the side away from the middle of the corresponding support plate 20, so as to tension the film in the front and rear directions to ensure the flatness of the film.

[0045] Before the driving rod 233 drives the fixed plate 221 to move to the right, the electric push rod 40 pushes the push-pull plate 41 to move upward, and the push-pull plate 41 drives the roller 223 to move upward and away from the film through the T-shaped slide bar 42 and the slider 224, and at the same time drives the roller 228 away from the film through the shaft seat 227. Then the driving rod 233 drives the rolling part 22 to move to the right and reset, and then the driving rod 233 pushes the rolling part 22 to move left again. At this time, the roller 228 and the roller 223 are both in contact with the film, and the film passing through is smoothed by the reciprocating movement of the rolling part 22.

[0046] like Figure 1 , Figure 4 and Figure 5 As shown, the rotating part 5 includes a slide plate 50, and the right ends of the two fixed plates 221 are jointly slidably installed with the slide plate 50, and the front end of the support plate 30 located on the front side of each group of winding mechanism 3 is provided with a No. 1 connecting plate 51 located between the corresponding feeding roller 31 and the corresponding shaft column 32, and the No. 1 connecting plate 51 is fixedly installed at the lower end of the slide plate 50, and a rotating shaft 52 located between the corresponding shaft column 32 and the corresponding No. 1 connecting plate 51 is rotatably installed on the support plate 30 located on the front side of each group of winding mechanism 3, and a rectangular plate 53 slidably installed on the support plate 30 up and down is arranged above the rotating shaft 52 and the shaft column 32, and a tensioning roller 54 is rotatably installed at the front end of the rectangular plate 53, and a spur gear 55 is fixedly installed at the front end of the feeding roller 31 and the front end of the rotating shaft 52, and a rack 56 meshing with the corresponding spur gear 55 is arranged at the upper and lower ends of the No. 1 connecting plate 51.

[0047] like Figure 1 As shown, the linkage portion 8 includes a waist-shaped groove 80, and the front end of the slide plate 50 is penetrated by a waist-shaped groove 80, which gradually tilts downward from front to back, and a No. 3 support plate 81 is fixedly installed on the right end of the push-pull plate 41, and a No. 2 guide column 82 that slides through the corresponding waist-shaped groove 80 is rotatably installed at the lower end of the No. 3 support plate 81.

[0048] During specific operation, when the driving part 23 drives the rolling part 22 to move to the left, the fixed plate 221 drives the slide plate 50 to move to the left, and the slide plate 50 drives the corresponding spur gear 55 to rotate through the rack 56, and the spur gear 55 drives the corresponding rotating shaft 52 and the unwinding roller 31 to rotate, and the rotating shaft 52 drives the shaft column 32 to rotate through the adjusting part 6, so that the rolling part 22 can smooth the film and reel in the smoothed film part at the same time, and before the driving part 23 drives the rolling part 22 to move to the right, the push-pull member 4 drives the push-pull plate 41 to move upward, and the roller shaft 223 and the roller 228 are away from the film. The film is moved, and the push-pull plate 41 also drives the No. 2 guide column 82 to move through the No. 3 support plate 81, and the No. 2 guide column 82 is used to cooperate with the corresponding waist groove 80 to drive the slide plate 50 to move forward, and the slide plate 50 drives the corresponding rack 56 to disengage from the corresponding spur gear 55 through the No. 1 connecting plate 51, and the shaft column 32 and the discharge roller 31 remain stationary under the action of the ratchet and pawl mechanism, so that after the rack 56 disengages from the spur gear 55, it can not only maintain the stability of the tensioned film, but also limit the rotation of the spur gear 55, ensuring that the rack 56 can mesh with the corresponding spur gear 55 again when it moves left next time.
