[0002] When some plastic packaging bags are being processed, they need to be flanging on the bag making machine, and the flanging process is performed by a folding device or flanging device provided on the bag making machine. In the current prior art, the more common flanging device is provided on the bag making machine frame, conveyed at an upward angle, and gradually flanging by a pressure wheel with a slope angle. However, in the process of rapid conveying and flanging of the plastic film, the flanging may not be in place, and the film may fail to flanging due to factors such as jamming, resulting in the failure of all flanging steps in the subsequent conveying process. Finally, the film is directly conveyed to the next process without being flanging. If this phenomenon is not promptly warned and discovered, a large amount of waste will be generated, resulting in great losses.

[0003] For example, the patent technology with application number 202123007450.8 in the prior art discloses a folding device for a bag making machine, which completes the flanging process of the film through the above-mentioned working principle, but its structure and function do not include a part for detecting the degree of flanging of the film and whether the flanging is smooth, and it is unable to perform self-inspection and alarm.

[0004] Therefore, designing an alarm mechanism that can monitor the film flanging situation in a segmented and multi-type manner, give abnormal alarms and emergency stops to avoid continuous waste generation and reduce cost waste is exactly the problem that the inventor wants to solve.

The frame 1 A first adjusting motor and a second adjusting motor are respectively provided at two ends, and the output end of the first adjusting motor is connected with a first screw rod, which is threadedly connected to an adjusting plate 4 on the left, and the output end of the second adjusting motor is connected with a second screw rod, which is threadedly connected to an adjusting plate 4 on the right, and a light hole for passing the second screw rod is provided on the adjusting plate 4 on the left, and a light hole for passing the first screw rod is provided on the adjusting plate 4 on the right. The position of the adjusting plate 4 can be adjusted by the rotation of the two motors by relying on the guide column 3 and the screw rod, and mounting columns 7 are provided on the inner sides of three of the six mounting holes through top screw locking, and a socket is provided on the mounting column 7, and a bracket for mounting a pressure wheel is provided on the inner side of the socket and is locked by a top screw. The height and angle of the pressure wheel can be adjusted by loosening the top screw, and the passing film can be flanged step by step through multiple pressure wheels.

[0025] The lower end surface of one end of the adjustment plate 4 is connected to an end connecting frame 105, and a first sensor 6 is arranged on the end connecting frame 105. The first sensor 6 is arranged at the place where the film first flanging begins to monitor the flanging condition of the film from the vicinity of the source of the flanging. If the film flanging is abnormal from the beginning, the first sensor 6 will not be able to sense the upright film and will be triggered.

[0026] An adjustment hole is provided on the mounting column 7, and an L-shaped bracket 9 is provided inside the adjustment hole. The L-shaped bracket 9 is locked with the mounting column 7 by a tightening bolt 8. The L-shaped bracket 9 rotates and slides with the adjustment hole. The L-shaped bracket 9 includes a vertical section, the upper part of the vertical section is a cylindrical structure and the lower part is a cube structure. The lower end of the vertical section is connected with a horizontal section, and a threaded hole that cooperates with a locking bolt 11 is provided at the end of the horizontal section. The bottom end of the L-shaped bracket 9 is connected to a connecting frame 10 through a locking bolt 11. The connecting frame 10 can rotate around the locking bolt 11 to adjust the angle, and the connecting frame 10 does not collide with other structures. The two connecting frames 10 located at the ends of one side of the same adjustment plate 4 are respectively provided with a second The sensor 14 and the third sensor 12 can adjust the position and height of the second sensor 14 and the third sensor 12 connected to the connecting plate by adjusting the height of the L-shaped bracket 9 and the angle of the connecting plate. The second sensor 14 is close to the first sensor 6 to detect whether the flanged film is conveyed normally. If the film is not erected normally and passes through the second sensor 14, the second sensor 14 will be triggered. The third sensor 12 is located at the very end of the flanging process. It determines whether there is an abnormality by sensing whether an erected film passes by. At the position of the third sensor 12, the film has completely finished flanging. If the third sensor 12 senses that an erected film passes by, it will be triggered.

[0027] An electric control box 15 is provided on both side walls of the frame 1, a controller is provided inside the electric control box 15, a support sleeve 16 is provided on the upper end of the electric control box 15, a buzzer 17 is provided on the upper end of the support sleeve 16, an alarm light 18 is provided on the upper end of the buzzer 17, and a touch screen is electrically connected to the controller. The controller is electrically connected to the buzzer 17, the alarm light 18, and the emergency stop module of the bag making machine, respectively. The controller is electrically connected to the first sensor 6, the second sensor 14, and the third sensor 12, respectively. The first sensor 6, the second sensor 14, and the third sensor 12 are arranged in order from low to high in height. When the first sensor 6, the second sensor 14, and the third sensor 12 are triggered, they will transmit signals to the controller. While the controller sends signals to the buzzer 17 and the alarm light 18 to make them work, it will also control the emergency stop module of the bag making machine connected thereto to take effect, so that the film on the production line stops being transported and produced.

The height of the contact switch 13 is higher than the second sensor 14 and lower than the third sensor 12. The contact switch 13 is electrically connected to the controller. The contact piece of the contact switch 13 is always in contact with the passing film and the contact is triggered by the film. The contact switch 13 can be installed or not. When it is not installed, the three sensors are used for flange monitoring. The installed contact switch 13 can be used as insurance. If there is no abnormality in the flanged film, the film passing the position of the contact switch 13 should be in a flipped up state, and the contact switch 13 squeezed by it will also be in a triggered state. The disconnection of the trigger state of the contact switch 13 proves that there is an abnormality in the film passing there. The signal is transmitted to the controller, and the controller will perform the same operation as mentioned above.

[0029] A circular hole for mounting in cooperation with the second sensor 14 and the third sensor 12 is provided in the middle of the end surface of the connecting frame 10 , and four threaded holes for mounting in cooperation with the contact switch 13 are evenly arranged around the circular hole.

[0030] The utility model adopts photoelectric sensors at multiple points and different heights to monitor the film flanging situation in real time. If the sensor loses the induction to the erected film, it will alarm and make an emergency stop. If the last sensor senses the erected film, it will alarm and make an emergency stop. In the process of film edge forming, the erected film part must pass through the path to coordinately set the contact switch 13. The contact switch 13 is triggered by the squeezing of the film. If the squeezing effect of the film is lost, the contact switch 13 is disconnected, which means an alarm and an emergency stop. Multiple sensors and switches act at the same time, taking into account the alarm operations of various abnormal situations, realizing the functions of segmented and multi-type monitoring of film flanging situation, abnormal alarm and emergency stop to avoid continuous generation of waste and reduce cost waste.
