DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0020] See also Figure 1 and Figure 2In this embodiment, an intelligent filling system based on light intensity double bag detection and high-precision quantitative measurement includes a filling machine 1, a frame 2 and a conveyor 4 arranged below the filling machine 1, and a filling head 3 fixed to the upper surface of the frame 2 and connected to the lower surface of the filling machine 1. A double bag detection device 5 is installed on the conveyor 4; the double bag detection device 5 includes a mounting frame 501, a horizontally arranged abutment frame 502 and a clamping frame 503. A fiber optic detection plate 504 is fixed on the side of the clamping frame 503 close to the abutment frame 502, and the abutment frame 502 is away from the abutment frame 502. One side of the clamping frame 503 is fixed to the mounting frame 501. A connecting arm 506 is fixed to the upper surface of the clamping frame 503. The upper surface of the mounting frame 501 is provided with an electric push rod 505 and a support frame 507. The output end of the electric push rod 505 is hinged to the connecting arm 506, and the connecting arm 506 is hinged to the outer wall of the support frame 507. Specifically, the filling machine 1, the frame 2, and the conveyor 4 are arranged in order from top to bottom. The electric push rod 505 is hingedly mounted on the upper surface of the mounting frame 501, and the support frame 507 is fixed to the upper surface of the mounting frame 501. This application uses a fiber optic detection plate 504 for transmissive light intensity analysis. Compared with traditional mechanical contact pressure detection, it can identify transparent and translucent bags, avoiding missed detection (such as PE film bags); has higher detection sensitivity for thin bags (<0.1mm), reducing the false positive rate to less than 0.1%; and eliminates physical contact, thus avoiding bag deformation or contamination. Mechanical clamping stabilizes the testing environment. The electric push rod 505 drives the clamping frame 503 to close in parallel through a hinge mechanism, ensuring that: the bag fits flatly in the testing area, eliminating wrinkles that interfere with the light path; the clamping force is controllable (usually set at 5-10N), which not only secures the bag but also prevents damage to the packaging.

[0021] It should be noted that test results are fed back to the filling machine PLC in real time: if a single bag passes, quantitative filling begins immediately (with an accuracy of ±0.5%); if double bags or no bags are present, filling is paused within 0.1 seconds and an alarm is issued to avoid material waste. Conveyor 4 starts and stops synchronously with the inspection station, eliminating the need for a buffer mechanism. Example

[0022] See also Figures 2 to 6The mounting frame 501 is provided with a cleaning device 6 for cleaning the optical fiber detection plate 504. The cleaning device 6 includes a housing 601, a cleaning wipe 602 fixed to one side of the housing 601, a driving roller 603 rotating on the side of the housing 601 away from the cleaning wipe 602, an eccentric wheel 605 rotating on the upper surface of the housing 601, a slide 606 slidingly arranged on the upper surface of the housing 601, and an infusion structure 607 fixed to the outer surface of the housing 601 and used in conjunction with the slide 606. A liquid storage cylinder 7 is fixed inside the housing 601, and a movable structure for moving the cleaning device 6 is provided on the mounting frame 501. A connecting shaft 6051 is fixed to the lower surface of the eccentric wheel 605, which is rotatably connected to the interior of the housing 601. A stirring shaft 8 extending into the interior of the liquid storage cylinder 7 is fixed to the bottom end of the connecting shaft 6051. The driving roller 603 is linked to the stirring shaft 8 via a synchronous belt 6043 to prevent the cleaning liquid in the liquid storage cylinder 7 from settling or stratifying, thereby ensuring concentration consistency.

[0023] In this embodiment, a drive structure 604 is disposed between the drive roller 603 and the connecting shaft 6051. The drive structure 604 includes a drive shaft 6041 fixed to the top of the drive roller 603. A drive wheel 6042 is fixed between the drive shaft 6041 and the connecting shaft 6051. A timing belt 6043 is connected between the two drive wheels 6042. Specifically, one side of the eccentric wheel 605 abuts against the outer surface of the slide 606. The housing 601 has a slot for the slide 606 to move, and a spring is installed in the slot to secure the slide 606.

[0024] In this embodiment, the infusion structure 607 includes a piston cylinder 6071 and a valve cylinder 6072 fixed to the outer surface of the housing 601. A piston block 6074 is disposed within the piston cylinder 6071. A valve stem 6075 extending to the exterior of the piston cylinder 6071 is fixed to the upper surface of the piston block 6074. A connecting sleeve 6076 is welded to the top of the valve stem 6075. A return spring 6077 is fixed between the connecting sleeve 6076 and the piston cylinder 6071. Infusion tubes 611 are fixed to both ends of the valve cylinder 6072. The two infusion tubes 611 are fixedly connected to the cleaning wipe 602 and the liquid storage cylinder 7, respectively. Two check valves 6073 are elastically hingedly connected to the interior of the valve cylinder 6072. Specifically, a connector is provided between the slide 606 and the connecting sleeve 6076. The connector includes a shaft 608 fixed to the interior of the connecting sleeve 6076, and a roller 609 is rotatably mounted on one end of the shaft 608. A rolling groove is provided inside the sliding seat 606 and is arranged obliquely and matched with the roller 609 , and the roller 609 is rollingly connected to the rolling groove.

[0025] In this embodiment, the movable structure includes an electric slide 612 slidably mounted on the upper surface of the mounting frame 501. An electric lift rod 613 is fixed to the electric slide 612. A fixed seat is fixed to the output end of the electric lift rod 613. A connecting rod 610 is fixed to the outer surface of the fixed seat and is fixed to the housing 601. The electric slide 612 and the electric lift rod 613 precisely position the cleaning wipe 602, ensuring complete coverage of the surface of the fiber optic detection plate 504 and preventing any omissions during manual cleaning.

[0026] The working principle of the above embodiment is: Conveyor 4 delivers the packaging bag to the filling station, double bag detection device 5 is activated, electric push rod 505 pushes clamping frame 503, so that the optical fiber detection plate 504 fits the packaging bag. The optical fiber transmitting end sends out a light signal, and the receiving end detects the light transmittance to determine whether it is a single bag, double bag, or no bag. Normal single bag: Filling machine 1 starts, and filling head 3 performs high-precision quantitative filling. Abnormal double bag or no bag, the system alarms and suspends filling, waiting for manual intervention or automatic correction; After the detection is completed, the cleaning device 6 is started, the electric slide 612 and the electric lifting rod 613 adjust the position of the cleaning wipe 602 so that it contacts the optical fiber detection plate 504, and the driving roller 603 drives the eccentric wheel 605 to rotate, causing the slide 606 to reciprocate, pushing the infusion structure 607 to release the cleaning liquid. The cleaning wipe 602 wipes the optical fiber detection plate 504 with the help of the cleaning liquid to prevent stains from affecting the detection accuracy.

Any connection method can be implemented as long as it can achieve its beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply.

Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so its specific structural composition and working principle will not be described in detail in this embodiment.
