Description

Technical Field

[0001] This utility model relates to the technical field of water-cut bag production, and in particular to a visual material feeding device for water-cut bag production. Background Technology

[0002] A water-cutting bag is a small mesh filter bag typically installed at the drain outlet of a kitchen sink, basin, or bathroom floor drain. Its core function is to physically intercept food scraps, hair, and other solid waste, separating water from debris and thus preventing pipe blockage. Common materials for water-cutting bags include polyester, non-woven fabric, or polyethylene.

[0003] In the large-scale production of water-cut bags, it is necessary to inspect product appearance, dimensions, and other indicators to screen out defective products and ensure the quality of goods leaving the factory. Traditional inspection methods rely heavily on manual visual judgment, which is not only inefficient and labor-intensive, but also prone to errors due to human fatigue and subjective judgment, making it difficult to meet the precise inspection requirements of mass production. With the application of automation technology, some production lines have introduced visual inspection equipment, but the cameras of existing visual feeding devices are mostly fixed installations. When faced with water-cut bag products of different sizes, the camera's focal length cannot be flexibly adapted, making it difficult to clearly capture the detailed information of products of different sizes, resulting in decreased inspection accuracy. Furthermore, when changing products, the entire equipment layout needs to be readjusted, which is cumbersome and inefficient, failing to meet the actual needs of diversified production.

[0004] In summary, there is a need for a visual material feeding device for water-cut bag production that can effectively detect water-cut bags of different sizes. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of the prior art by providing a visual material feeding device for water-cut bag production that can effectively detect water-cut bags of different sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A visual material feeding device for water-cut bag production includes: frame; A water-cutting bag conveyor belt, which is mounted on the frame; A camera is mounted on the frame and located above the water-cutting bag conveyor belt, and the camera and the frame are vertically connected. A defective product discharge push rod is fixed on the frame and located above the water-cutting bag conveyor belt, and the defective product discharge push rod is positioned behind the camera; A defective product collection bin is placed below the water-cutting bag conveyor belt, and the defective product collection bin and the defective product discharge push rod are arranged symmetrically about the water-cutting bag conveyor belt.

[0007] The water-cut bags are conveyed to the inspection area below the camera via a conveyor belt. After the camera captures the image and completes the inspection, defective bags are pushed into the collection bin below by a discharge pusher, while qualified bags continue to flow with the conveyor belt. By adjusting the vertical height of the camera on the frame, the inspection focal length can be adapted to different sizes of water-cut bags, effectively inspecting water-cut bags of various sizes and improving inspection accuracy.

[0008] Preferably, a fixed base plate is fixed on the frame, and a lifting plate is arranged below the fixed base plate. The camera is fixed on the lower end face of the lifting plate, and a lifting rod and a limiting guide rod are fixed on the upper end face of the lifting plate. The lifting rod and the limiting guide rod are parallel to each other. The fixed base plate is provided with a lifting rod clearance hole and a guide rod through hole. The lifting rod and the limiting guide rod are respectively placed inside the lifting rod clearance hole and the guide rod through hole and are both vertically connected. An operating knob is installed at the lifting rod clearance hole. The operating knob is rotatably connected to the fixed base plate. The operating knob is provided with an internal threaded hole, and the outer wall of the lifting rod is provided with an external threaded area that matches the internal threaded hole. The lifting rod is threadedly connected to the operating knob through the cooperation of the external threaded area and the internal threaded hole. When inspecting water-cut bags of different sizes, rotating the operating knob on the fixed base plate drives the lifting rod and the limiting guide rod to move up and down through the threaded engagement, so that the lifting plate drives the camera to adjust its height to adapt to the focal length. The operation is simple and the control is convenient.

[0009] Preferably, a first boss is fixed on the fixed base plate, and the lifting rod clearance hole is placed on the first boss. An annular limiting groove is provided on the first boss, and the lifting rod clearance hole is located at the inner center of the annular limiting groove. An annular limiting slider matching the annular limiting groove is fixed on the operating knob. The operating knob is mounted on the first boss and rotatably connected to it through the cooperation of the annular limiting slider and the annular limiting groove. By providing an annular limiting groove on the first boss of the fixed base plate, and achieving a rotatable connection with the annular limiting slider of the operating knob, the axial offset of the operating knob when adjusting the camera height can be limited, ensuring stable lifting of the lifting rod, thereby guaranteeing the accuracy of camera focus adjustment and the stability of equipment operation.

[0010] Preferably, a second boss is also fixed on the fixed base plate, the guide rod through hole is placed on the second boss, and a locking clamp is installed on the inner wall of the guide rod through hole. The locking clamp is directly opposite the limiting guide rod and is movably connected to the guide rod through hole. Through the design of the locking clamp, the limiting guide rod can be clamped after the camera height is adjusted to the correct position, preventing the limiting guide rod from shaking and causing the camera to shift during equipment operation, further ensuring the stability of the detection focal length and the detection accuracy.

[0011] Preferably, the locking clamps are two pieces arranged opposite to each other. The inner wall of the guide rod through hole has a clamping groove that matches the locking clamp. An air pressure channel is provided between the bottom surface of the clamping groove and the surface of the second boss. The lengths of the air pressure channels corresponding to the two locking clamps are the same. The locking clamps are pneumatically driven to clamp or release the limiting guide rod. By arranging the two locking clamps opposite to each other and ensuring that their corresponding air pressure channels are of the same length, the two locking clamps can be driven to move synchronously towards each other, achieving uniform clamping of the limiting guide rod, preventing the limiting guide rod from shifting during clamping, further ensuring the stability of the camera after its height is fixed, and improving detection accuracy.

[0012] Preferably, a flexible anti-slip layer is fixed to the side of the locking clamp facing the limiting guide rod. This flexible anti-slip layer design increases the friction between the clamp and the guide rod, preventing slight displacement of the guide rod due to vibration during equipment operation. It also prevents wear and vibration on the limiting guide rod when the rigid clamp is tightened, balancing limiting stability and component protection, further ensuring the camera's focal length fixing accuracy.

[0013] The beneficial effects of this utility model are: it can effectively detect water-cut bags of different sizes, improving detection accuracy; it is simple to operate and easy to control; it ensures the precision of camera focus adjustment and the stability of equipment operation; it ensures the stability of detection focus and detection accuracy; and it ensures the stability of the camera after the height is fixed, improving detection accuracy.
