Description

Technical Field

[0001] This utility model belongs to the field of automatic alarm equipment technology, and in particular relates to an automatic alarm device for membrane breakage. Background Technology

[0002] A film breakage alarm device is an automated device used to monitor whether film materials break during the production process. It is widely used in packaging, agriculture, industrial production and other fields. The device uses sensors to detect the operating status of the film in real time. Once a film breakage is detected, it immediately triggers an audible and visual alarm to remind operators to deal with it in time, prevent the equipment from running idle, reduce product quality or interrupt production, thereby improving production efficiency and safety and reducing material waste.

[0003] The problems with existing technologies are that existing equipment often adopts a fixed installation structure, which makes it impossible to flexibly adjust the installation position of photoelectric sensors according to actual production needs. This makes it difficult to adapt to the detection needs of thin film materials with different widths, thicknesses, or running trajectories. At the same time, the sensors are mostly fixed as a whole, making disassembly and replacement difficult and maintenance inefficient. After long-term use, dust accumulation or component aging can affect the detection accuracy, thereby reducing the overall stability and practicality of the equipment. Utility Model Content

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, an automatic alarm device for membrane breakage provided by this utility model embodiment includes a fixed plate 1, a movable plate 2, and a mounting plate 3. The movable plate 2 is placed on the right side of the fixed plate 1, and the left side of the movable plate 2 is slidably connected to the right side of the fixed plate 1. A connecting groove 13 is provided on the right side of the movable plate 2.

The other ends of the springs 9 are fixedly connected to connecting plates 10. Each side of the connecting plates 10 that are close to each other is fixedly connected to a fixing rod 11. The ends of the fixing rods 11 that are close to each other pass through and extend into the interior of the connecting groove 13. The surface of the mounting plate 3 has a fixing hole 12. The fixing hole 12 and the fixing rod 11 are used in conjunction with each other.

[0023] By adopting the above solution, the mounting plate 3 can be quickly disassembled and assembled by setting the fixing rod 11 and the spring 9, thereby improving the convenience of maintenance and the adaptability of the equipment.

[0024] refer to Figure 3 Each of the receiving blocks 7 has a through groove 14 on its left side. Each of the connecting plates 10 has a slider 15 fixedly connected to its left side. The sliders 15 are slidably connected to the inside of the through groove 14. Each of the receiving blocks 7 has a guide plate 16 on its right side. The front and rear sides of the right surface of the guide plate 16 are slidably connected to the left side of the receiving block 7. Each of the guide plates 16 has a guide groove 17 on its surface. The guide groove 17 is inclined at a certain angle. The sliders 15 are slidably connected to the inside of the guide groove 17.

[0025] By adopting the above solution: by setting the guide plate 16, the slider 15 can be moved along the guide groove 17 by pulling, thereby driving the connecting plate 10 and the fixing rod 11 to retract synchronously, realizing the quick unlocking and disassembly of the mounting plate 3, making the operation more convenient and labor-saving.

[0026] refer to Figure 3A pull frame 18 is placed at the bottom of the movable plate 2, and the front and rear sides of the top of the pull frame 18 are fixedly connected to the bottom of the guide plate 16.

[0027] Using the above solution: by setting up the pull frame 18, the guide plates 16 on both sides can be pulled simultaneously by manual operation, thereby synchronously driving the slider 15, the connecting plate 10 and the fixing rod 11 to move, so as to realize the synchronous unlocking of both sides of the mounting plate 3.

[0028] refer to Figure 4 Two stabilizing rods 19 are placed inside the receiving groove 8. The front and rear ends of the stabilizing rods 19 are fixedly connected to the surface of the receiving groove 8. The upper and lower sides of the connecting plate 10 are slidably connected to the surface of the stabilizing rods 19.

[0029] By adopting the above solution, the stability of the connecting plate 10 during movement can be effectively improved by setting the stabilizer bar 19, preventing deviation or jamming, thereby ensuring the smoothness of locking and unlocking actions.

[0030] refer to Figure 1 The right side of the fixed plate 1 has a groove 20, and a lead screw 21 is placed inside the groove 20. The bottom of the lead screw 21 is rotatably connected to the bottom of the groove 20. The left side of the movable plate 2 is slidably connected to the inside of the groove 20, and the left side of the movable plate 2 is threadedly connected to the surface of the lead screw 21.

[0031] By adopting the above solution, the horizontal position of the photoelectric sensor 4 can be precisely adjusted according to the usage requirements by setting the lead screw 21, thereby improving the flexibility and applicability of the equipment.

[0032] refer to Figure 1 The top of the lead screw 21 extends through and out of the top of the fixed plate 1, and a rotating handle 22 is fixedly connected to the top of the lead screw 21.

[0033] By adopting the above solution, by setting the rotary handle 22, a convenient adjustment handle can be provided for the operator, making the rotation of the lead screw 21 more effortless and intuitive, thereby achieving precise control of the position of the moving plate 2 and the photoelectric sensor 4.

[0034] The working principle of this utility model is as follows: In use, first install the fixing plate 1 in a suitable working position. Then, rotate the screw 21 by rotating the handle 22. The screw 21 drives the moving plate 2 to move, and the moving plate 2 further drives the mounting plate 3 and the photoelectric sensor 4 to move. When the photoelectric sensor 4 is adjusted to the required detection position, stop rotating the screw 21 to complete the position adjustment. Subsequently, the device can be put into normal operation to monitor the film status in real time. After the equipment has been used for a period of time, the photoelectric sensor 4 and other components need to be inspected or maintained. During disassembly, first pull the pull frame 18. The pull frame 18 drives the guide plates 16 on both sides to move. Since the slider 15 is slidably connected to the inside of the through groove 14, the slider 15 can only move back and forth along the through groove 14. When the guide plate 16 moves downward, the sliders 15 on both sides will move synchronously in the opposite direction due to the tilt angle of the guide groove 17. Then the slider 15 drives the connecting plate 10 to move, and the connecting plate 10 drives the fixing rod 11 to move. After the fixing rod 11 is removed from the fixing hole 12, the mounting plate 3 can be smoothly disassembled along the connecting groove 13, so as to carry out subsequent inspection and maintenance operations on the photoelectric sensor 4 and related components.

[0035] In summary, this automatic membrane breakage alarm device, through the coordinated use of a fixed plate 1, a movable plate 2, a mounting plate 3, a photoelectric sensor 4, a controller 5, a buzzer 6, a receiving block 7, a receiving groove 8, a spring 9, a connecting plate 10, a fixing rod 11, a fixing hole 12, a connecting groove 13, a through groove 14, a slider 15, a guide plate 16, a guide groove 17, a pulling frame 18, a stabilizing rod 19, a groove 20, a lead screw 21, and a rotating handle 22, solves the problems of existing equipment often using a fixed installation structure, which makes it impossible to flexibly adjust the installation position of the photoelectric sensor according to actual production needs, making it difficult to adapt to the detection needs of thin film materials with different widths, thicknesses, or running trajectories. At the same time, the sensors are mostly integrally fixed connections, making disassembly and replacement difficult, maintenance efficiency low, and long-term use is prone to dust accumulation or component aging affecting detection accuracy, thus reducing the overall stability and practicality of the equipment.
