[0023] See also Figure 1-Figure 5As shown, a double-sided gluing and flanging device for plastic film comprises a base 1 and an automatic gluing device 2; the automatic gluing device 2 is provided with a conveying frame 21, a stepping motor 24 is fixedly provided on one side of the conveying frame 21, a transmission wheel 25 is fixedly provided on the output end of the stepping motor 24, a transmission belt 26 is transmission-connected around the transmission wheel 25, a driven wheel 27 is transmission-connected on the other side of the transmission belt 26, a rotating wheel 28 is passed through and fixedly provided on one side of the driven wheel 27, two ends of the rotating wheel 28 are movably provided with the conveying frame 21, two conveying belts 29 are movably provided with the rotating wheel 28, and one side of the two conveying belts 29 is movably provided with the conveying frame 21;

[0024] When working, the stepper motor 24 is driven to provide power. When the stepper motor 24 works, the transmission wheel 25 rotates, and the cooperation with the transmission belt 26 and the driven wheel 27 makes the rotating wheel 28 rotate accordingly on the conveying frame 21, so that the conveyor belt 29 rotates on the conveying frame 21, which is beneficial to the conveying of the plastic film.

[0025] Furthermore, the base 1 is installed with a fixing frame 11, a working platform 13 is fixedly installed on the top of the fixing frame 11, and four universal wheels 12 are fixedly installed on the bottom of the working platform 13;

[0026] During operation, the installation of the universal wheels 12 on the base 1 can increase the overall convenience when the entire device needs to be moved. The cooperation between the fixed frame 11 and the working platform 13 can support the components on the top and ensure the stability of the overall operation.

[0027] Furthermore, a conveying frame 21 is fixedly installed on the top of the working platform 13, a support rod 22 is fixedly installed on the bottom of the working platform 13, an infrared trigger camera 23 is fixedly installed on the top of the support rod 22, and a fixed box 37 is fixedly installed on the top of the working platform 13;

[0028] When working, the infrared trigger camera 23 is composed of a receiver and a camera. The transmitter emits a beam of infrared light that is invisible to the human eye, facing the corresponding receiving window on the receiver. When a moving object passes between the transmitter and the receiver, the infrared beam is blocked, thereby sending a signal to the vacuum generator 33 to drive it to work.

[0029] Furthermore, a servo motor 38 is fixedly installed on one side of the fixed box 37, a fixed gear 36 is fixedly installed on the output end of the servo motor 38, a linkage gear 31 is transmission-connected to one side of the fixed gear 36, and a conveying frame 21 is movably installed on one side of the linkage gear 31;

[0030] During operation, the servo motor 38 drives the fixed gear 36 to rotate. When the fixed gear 36 rotates, it transmits power to the linkage gear 31 to make it rotate accordingly on the conveying frame 21.

[0031] Furthermore, a connecting rod 32 is fixedly installed on one side of the linkage gear 31, a vacuum generator 33 is fixedly installed on the other end of the connecting rod 32, and a first suction cup 34 is fixedly installed on the output end of the vacuum generator 33;

[0032] During operation, when the vacuum generator 33 receives a signal to start working, it drives the first suction cup 34 to absorb the plastic film on the top, so that the first suction cup 34 limits the plastic film, and at the same time, the position of the plastic film is turned over in coordination with the rotation of the linkage gear 31.

[0033] Furthermore, a heating block 35 is fixedly installed on the top of the first suction cup 34, a second suction cup 39 is movably connected to one side of the heating block 35, and a conveying frame 21 is fixedly installed on both sides of the second suction cup 39;

[0034] During operation, when the plastic film is moved to a certain position, the gap between the second suction cup 39 and the first suction cup 34 is used to fit the plastic film on both sides, and the heating block 35 is used to heat the plastic film under the limit of the second suction cup 39 and the first suction cup 34 to achieve edge adhesion of the plastic film.

[0035] Working principle: By driving the stepper motor 24, the transmission wheel 25 is rotated, and the transmission wheel 25 transmits the driven wheel 27 through the transmission belt 26, so that the driven wheel 27 is linked with the rotating wheel 28 to rotate accordingly, and the two sides of the rotating wheel 28 drive the coordinated conveyor belt 29 to realize the rotation of the conveyor belt 29 on the conveyor frame 21, so that the top of the conveyor belt 29 contacts the plastic film and conveys the plastic film. When the plastic film is conveyed to one side of the heating block 35, infrared monitoring is performed through the infrared trigger camera 23. When it is detected that the plastic film moves to the detection point, the vacuum generator is driven The vacuum generator 33 generates suction force on the first suction cup 34, so that the first suction cup 34 adsorbs the bottom of the plastic film to limit the plastic film, and at the same time drives the servo motor 38 to rotate the fixed gear 36, so that the clearance between the fixed gear 36 and the linkage gear 31 is matched to realize the rotation of the linkage gear 31. When the linkage gear 31 rotates, the connecting rod 32 links the vacuum generator 33 and the first suction cup 34 to move in a circle to one side, so that the first suction cup 34 drives the plastic film to fit the plastic film on the top of the second suction cup 39, and the plastic film is adhered to both sides under the action of the heating block 35.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
