[0004] To achieve the above purpose, the utility model provides the following technical solution:

[0005] An automatic film tearing mechanism includes an installation gantry. A support plate is fixedly installed at the bottom end of the installation gantry. A lifting cylinder is installed at the top end of the support plate. The telescopic rod of the lifting cylinder passes through the support plate and extends to the bottom side of the installation gantry. An installation plate is arranged at the bottom side of the installation gantry. The telescopic rod of the lifting cylinder is fixedly connected to the top end of the installation plate. First connecting plates are fixedly installed around the four sides of both sides of the support plate. A pressing component is fixedly installed at one side of the bottom end of the installation plate. A support frame is fixedly installed at the side of the installation plate away from the pressing component. A winding rod and a raw material rod are rotatably arranged on the same side of the installation plate as the pressing component. The winding rod and the raw material rod are respectively rotatably installed on both sides of the winding rod. A torque motor and a servo motor are installed on both sides of the support frame. The torque motor and the servo motor are respectively connected to one end of the raw material rod and the winding rod through couplings. A tape is installed on the raw material rod. A rotating shaft is rotatably installed at the bottom end on the same side of the installation plate as the winding rod and the raw material rod. A film product is arranged at the bottom of the pressing component.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The tape is used to automatically remove the protective film. When the diaphragm is transported to below the pressing assembly on the equipment, the pressing assembly is driven by the lifting cylinder to descend, so that the protective film on the product adheres to the tape. The pressing assembly rises to separate the protective film from the product. The servo motor drives the winding rod to wind the tape with the protective film around the winding rod. A torque motor is installed behind the raw material rod to ensure the tension of the tape, realizing continuous operation of removing the protective film, reducing one personnel allocation, and the efficiency of the machine is much higher than that of manual labor.

[0019] Embodiment

[0020] Please refer to Figures 1 to 5 In the embodiment of the present utility model, an automatic film tearing mechanism includes an installation gantry 7. A support plate 22 is fixedly installed at the bottom end of the installation gantry 7. A lifting cylinder 8 is installed at the top end of the support plate 22. The telescopic rod of the lifting cylinder 8 passes through the support plate 22 and extends to the bottom side of the installation gantry 7. An installation plate 13 is arranged at the bottom side of the installation gantry 7. The telescopic rod of the lifting cylinder 8 is fixedly connected to the top end of the installation plate 13. First connecting plates 15 are fixedly installed around the two sides of the support plate 22. A sliding sleeve 16 is fixedly installed on the first connecting plate 15. The sliding sleeve 16 is in communication with the first connecting plate 15. A fixed seat 21 is fixedly installed at the top end of the installation plate 13. A sliding rod 14 is fixedly installed in the fixed seat 21. The sliding rod 14 passes through the first connecting plate 15 and the sliding sleeve 16 and extends to the top of the installation gantry 7 and is slidably connected to the first connecting plate 15 and the sliding sleeve 16. A connecting rod 17 is fixedly installed between the top ends of the sliding rods 14. A screw rod 20 is threadedly installed in the middle of the connecting rod 17. Second connecting plates 18 are fixedly installed at the middle positions on both sides of the support plate 22. The second connecting plate 18 is directly below the screw rod 20. A bottom block 19 is fixedly installed at the top end of the second connecting plate 18. When the lifting cylinder 8 is started, the telescopic rod of the lifting cylinder 8 can drive the installation plate 13 to move up and down. Since the sliding rod 14 is installed at the top end of the installation plate 13 through the fixed seat 21 and the sliding rod 14 is slidably connected to the first connecting plate 15 and the sliding sleeve 16, the installation plate 13 drives the sliding rod 14 to slide in the first connecting plate 15 and the sliding sleeve 16. When the sliding rod 14 slides downward, it will drive the connecting rod 17 to descend. Since the screw rod 20 is installed on the connecting rod 17, the connecting rod 17 drives the screw rod 20 to descend. When the bottom end of the screw rod 20 contacts the bottom block 19, the screw rod 20 can be limited. By limiting the screw rod 20, the sliding rod 14 can be prevented from sliding, so that the installation plate 13 stops descending;

[0021] Please refer to Figures 1 to 5, a pressing-down component 2 is fixedly installed on one side of the bottom end of the mounting plate 13. A support frame 12 is fixedly installed on the side of the mounting plate 13 away from the pressing-down component 2. A coiling rod 1 and a raw material rod 5 are rotatably arranged on the same side of the mounting plate 13 as the pressing-down component 2. The coiling rod 1 and the raw material rod 5 are respectively rotatably installed on both sides of the coiling rod 1. A torque motor 9 and a servo motor 10 are installed on both sides of the support frame 12. The torque motor 9 and the servo motor 10 are respectively connected to one end of the raw material rod 5 and the coiling rod 1 through couplings. A tape 6 is installed on the raw material rod 5. A rotating shaft 11 is rotatably installed at the bottom end of the mounting plate 13 on the same side as the coiling rod 1 and the raw material rod 5. A tape length sensor 4 is installed on the mounting plate 13 and below the tape 6. A diaphragm product 3 is arranged at the bottom of the pressing-down component 2. One end of the tape 6 is passed through the rotating shaft 11 and the bottom end of the pressing-down component 2 and connected to the coiling rod 1. When the diaphragm product 3 moves to the bottom end of the pressing-down component 2, the lifting cylinder 8 is started, and the mounting plate 13 is driven to descend through the telescopic rod of the lifting cylinder 8. The pressing-down component 2 is driven to descend through the mounting plate 13. The tape 6 is driven to contact the top end of the diaphragm product 3 through the descent of the pressing-down component 2. The protective film on the diaphragm product 3 is pasted through the tape 6. After the tape 6 pastes the protective film, the lifting cylinder 8 is started, and the mounting plate 13 is driven to rise through the telescopic rod of the lifting cylinder 8 rising. The pressing-down component 2 is driven through the mounting plate 13 to drive the tape 6 to rise. The protective film can be separated from the diaphragm product 3 through the tape 6. The servo motor 10 is started, and the motor shaft of the servo motor 10 drives the coiling rod 1 to rotate through the coupling. The tape 6 with the protective film is wound onto the coiling rod 1 through the rotation of the coiling rod 1. The position of the raw material rod 5 can be adjusted through the rotation of the torque motor 9, so as to drive the position adjustment of the tape 6 to ensure the tension of the tape 6, realizing continuous operation of tearing the protective film, reducing one personnel configuration, and the efficiency of the machine is much greater than that of manual work. The remaining amount of the tape 6 can be sensed through the tape length sensor 4, which is convenient for replacement.
