It should be noted that the embodiments described below are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0022] See Figure 1This embodiment provides a stability detection device for auxiliary feeding, installed on the feeding mechanism 11 and cutting mechanism 12 arranged in front and behind each other. Specifically, it includes a PLC controller, a measuring component, a limit component, and a display and warning component. In this embodiment, the display and warning component (not shown) can be set separately from the measuring component, limit component, and display and warning component, depending on the production environment, and installed in an easily operable position. It includes a touch display panel and an audible and visual alarm device composed of a buzzer and LED lights. The PLC controller (not shown) is connected to the first encoder 23, the second encoder 32, and the shaft drive in the measuring component, limit component, and display and warning component. The motor 25, the first sensing device 41, the second sensing device 42, the touch display panel, the audible and visual alarm device, the feeding mechanism 11, and the cutting mechanism 12 are electrically connected to perform overall monitoring and control of the device. It is worth noting that the PLC controller is a logic controller. It remotely inputs control-related instructions through the touch display panel and remotely controls the first encoder 23, the second encoder 32, the shaft drive motor 25, the first sensing device 41, the second sensing device 42, the touch display panel, the audible and visual alarm device, the feeding mechanism 11, and the cutting mechanism 12 through logic signals. These are existing mature technologies and are well known in the current field. Therefore, their electrical connections will not be described in detail.

[0023] The measuring component is used to set and determine the single feeding length of the plate 81, and includes an active measuring wheel set and a driven measuring wheel set on the feeding mechanism 11, and a sensing auxiliary component on the cutting mechanism 12;

[0024] The active measuring wheel assembly includes a height adjustment bracket 21, an active rotating shaft 22, a first encoder 23, an active measuring wheel 24, and a rotating shaft drive motor 25. In this embodiment, the height adjustment bracket 21 is horizontally arranged above the worktable of the feeding mechanism 11, including a left adjusting rod 211 and a right adjusting rod 212 mounted on a crossbar. The left adjusting rod 211 and the right adjusting rod 212 are symmetrically arranged on both sides of the worktable of the feeding mechanism 11. The active rotating shaft 22 is height-adjustable between the left adjusting rod 211 and the right adjusting rod 212. Its first end is connected to the output end of the rotating shaft drive motor 25, and its last end is connected to the... The first encoder 23 is connected; the active measuring wheel 24 is rotatably mounted through the active rotating shaft 22, and its main body is suspended below the mounting crossbar. The surface of the active measuring wheel 24 is covered with a rubber anti-slip layer 241, and it is provided with regular toothed protrusions 242. Rubber anti-slip dots (not shown in the figure) are also distributed on the toothed protrusions 242. The overall design of the active measuring wheel group can ensure that during the feeding process, regardless of the thickness of the plate 81, the active measuring wheel always presses lightly on the upper surface of the plate 81, and actively rotates a specific number of times to stably drive the plate 81 to feed and determine the feeding length of the plate 81.

[0025] The driven measuring wheel assembly includes a driven rotating shaft 31, a second encoder 32, and a driven measuring wheel 33. The driven rotating shaft 31 is located directly below the mounting crossbar, and its body extends laterally through the worktable of the feeding mechanism 11. Its end is connected to the second encoder 32. The driven measuring wheel 33 is rotatably mounted through the driven rotating shaft 31, and the driven measuring wheel 33 has the same diameter as the active measuring wheel 24. In this embodiment, the highest point of the driven measuring wheel 33 is 0.5 to 0.8 cm above the worktable surface of the feeding mechanism 11. Both the first encoder 23 and the second encoder 32 are photoelectric encoders.

[0026] The sensing auxiliary component includes a first sensing device 41 and a second sensing device 42. In this embodiment, both the first sensing device 41 and the second sensing device 42 are infrared sensing devices, that is, each includes an infrared transmitter and an infrared receiver. The infrared transmitter and infrared receiver of the first sensing device 41 are symmetrical to each other and are respectively disposed on the left and right placement frames 512 and 513 of the width adjustment bracket 51 corresponding to the position of the cutting component 13 of the cutting mechanism 12. The infrared transmitter and infrared receiver of the second sensing device 42 are symmetrical to each other and are respectively slidably disposed on the left and right placement frames 512 and 513 of the width adjustment bracket 51 corresponding to a certain position of the cutting mechanism 12. The first sensing device 41 is disposed between the second sensing device 42 and the feeding mechanism 11.

[0027] The limiting assembly includes a width adjusting bracket 51, a limiting side plate assembly 61, and a limiting rotary cylinder assembly 71. In this embodiment, the width adjusting bracket 51 is generally U-shaped and specifically includes an adjustable crossbar 511, a left placement frame 512, and a right placement frame 513. The left placement frame 512 and the right placement frame 513 are parallel to the worktable of the feeding mechanism 11 and the cutting mechanism 12, and are respectively placed on the left and right sides of the feeding mechanism 11 and the cutting mechanism 12. Their lengths are consistent with the overall length of the feeding mechanism 11 and the cutting mechanism 12 arranged in front and behind. The adjusting crossbar 511 is designed with... Multiple rods are provided, all passing through the space below the worktable of the feeding mechanism 11 and the cutting mechanism 12 and connecting between the left placement frame 512 and the right placement frame 513. The width between the left placement frame 512 and the right placement frame 513 can be adjusted by adjusting the length of the adjusting crossbar 511 to accommodate plates 81 of different widths. In this embodiment, the left placement frame 512 and the right placement frame 513 are provided with a slide rail 514 at a certain position of the cutting mechanism 12. The infrared transmitter and infrared receiver of the second sensing device 42 are slidably mounted on the slide rail 514.

[0028] The limiting side plate assembly 61 includes a symmetrically arranged left limiting plate and a right limiting plate. The left limiting plate and the right limiting plate are respectively installed on the left placement frame 512 and the right placement frame 513 of the width adjustment bracket 51 at a position corresponding to a section of the feeding mechanism 11 at the end away from the cutting mechanism 12. The limiting rotary cylinder assembly 71 includes a symmetrically arranged left limiting rotary cylinder assembly 71 and a right limiting rotary cylinder assembly 71. The left limiting rotary cylinder assembly 71 and the right limiting rotary cylinder assembly 71 are respectively installed on the left placement frame 512 and the right placement frame 513 of the width adjustment bracket 51 at a position corresponding to a section of the feeding mechanism 11 at the end near the cutting mechanism 12. Each assembly includes several vertically arranged limiting rotary cylinders, which are used to continuously rotate with the plate 81 during the feeding process, reduce the friction when the plate 81 moves, and ensure that the plate 81 does not deviate during movement, thus assisting in completing the feeding.

[0029] In this embodiment, in the initial state, the feeding length of the board 81 is set on the touch display panel according to the actual production requirements. The PLC controller sets the number of rotations of the active rotating shaft 22 through the first encoder 23 according to this setting. The infrared receivers of the first sensing device 41 and the second sensing device 42 can successfully receive the infrared signals emitted by their corresponding infrared transmitters.

[0030] When the feeding and cutting work begins, the rotating shaft drive motor 25 drives the active rotating shaft 22 to rotate the active measuring wheel 24 any number of times until the plate 81 moves forward to the cutting mechanism 12. When the PLC controller receives information that the infrared receiver of the first sensing device 41 cannot receive the infrared signal emitted by its corresponding infrared transmitter because the plate 81 is blocked, it means that the front end of the plate 81 has successfully reached the cutting part 13 of the cutting mechanism 12, and the automatic feeding and cutting of the plate 81 can be carried out.

[0031] During the feeding and cutting process, when the sheet metal 81 reaches the cutting component 13 of the cutting mechanism 12, the rotating shaft drive motor 25 briefly stops rotating. Then, it rotates cyclically a fixed number of times via the first encoder 23 according to the settings of the PLC controller. The active measuring wheel 24 also rotates cyclically a fixed number of times, thereby driving the sheet metal 81 to move forward intermittently by a fixed length. This achieves multiple stable feedings of the sheet metal 81 with precise length. Each time the sheet metal 81 moves a fixed length, the cutting component 13 of the cutting mechanism 12 cuts the sheet metal 81, ensuring that each segment of the sheet metal 81 after cutting is of the same length and conforms to the specified dimensions. The set values ​​are consistent; during the feeding process of the plate 81, the driven measuring wheel 33 rotates in a cycle under the drive of the plate 81, and the driven rotating shaft 31 and the second encoder 32 also rotate in a cycle, and send the number of rotations each time to the PLC controller. The PLC controller compares whether the actual number of rotations of the driven measuring wheel 33 is the same as the set number of rotations each time. If the comparison result is different, it means that the actual feeding length of the plate 81 is different from the set value. The PLC controller controls the cutting mechanism 12 to stop cutting, and at the same time controls the buzzer and LED light group to alarm, and displays the relevant comparison values ​​on the touch display panel.

[0032] During this process, the infrared transmitter and infrared receiver of the second sensing device 42 slide according to the set feeding length to ensure that the distance between it and the first sensing device 41 is consistent with the set feeding length. When the board 81 completes its movement, if the PLC controller receives information that the infrared receiver of the second sensing device 42 can still receive the infrared signal emitted by its corresponding infrared transmitter, it also indicates that the actual feeding length of the board 81 is different from the set value. The PLC controller controls the cutting mechanism 12 to stop cutting, and at the same time controls the buzzer and LED light group to sound an alarm, and displays the relevant comparison values ​​on the touch display panel.

[0033] In this embodiment, the above is merely an example and is not intended to limit the scope of protection of this application.

[0034] This utility model provides a stability detection device for auxiliary feeding. A measuring component, a limiting component, and a display and warning component are sequentially arranged on the feeding mechanism and the cutting mechanism arranged in a front-to-back configuration. The measuring component includes an active measuring wheel assembly consisting of a height adjustment bracket, an active rotating shaft, a first encoder, and an active measuring wheel; and a driven measuring wheel assembly consisting of a driven rotating shaft, a second encoder, and a driven measuring wheel.

The height of the active measuring wheel can be adjusted by the height adjustment bracket to accommodate different thicknesses. The feeding system is designed to meet the specific requirements of sheet metal, and its surface is equipped with toothed protrusions that can rotate to contact the sheet metal surface, ensuring stable and continuous feeding. It also ensures that even if the feeding speed changes, the sheet metal will not slip or shift. The limiting component includes a limiting side plate assembly to prevent the sheet metal from tilting during feeding and a limiting rotary cylinder assembly to prevent sheet metal displacement while assisting in sheet metal movement. The display and warning component includes a touch display panel and an audible and visual alarm device. The touch display panel is used to preset the number of rotations of the active rotating shaft and receive the actual feeding length of the sheet metal.
