Description

Technical Field

[0001] This utility model relates to the field of silkworm cocoon processing technology, and in particular to a silkworm cocoon screening device. Background Technology

[0002] Silkworm cocoon screening is a key process in silk processing, directly affecting the quality of raw silk and production efficiency. Traditional manual sorting methods are labor-intensive and have unstable accuracy. Mechanized screening devices, on the other hand, use automated means to grade silkworm cocoons based on their integrity, size, and color, and have become the core equipment of modern silk reeling plants. An efficient and reliable silkworm cocoon screening device is of great significance for improving the standardization level of the silk industry.

[0003] Currently, many small and medium-sized factories still rely on manual screening. Workers lay silkworm cocoons flat on the workbench and visually inspect each cocoon to determine its integrity, size, and color. Qualified and substandard products are then manually sorted and placed into different containers. The core of this process relies on the operator's experience and manual operation, without the intervention of mechanized sorting structures.

[0004] While the above-mentioned manual sorting method can flexibly handle silkworm cocoons of different sizes, it has certain drawbacks. The sorting efficiency is low and consistency is difficult to guarantee. Operators need to concentrate for a long time, which can easily lead to a higher rate of missed detection due to visual fatigue. At the same time, the results of manual sorting are significantly affected by subjective factors, making it difficult to achieve standardized grading, which seriously restricts the stability of product quality and the efficiency of mass production. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a silkworm cocoon screening device, which aims to improve the low efficiency of manual sorting.

[0008] Furthermore, the locking assembly includes a disc, a slot, and a lever. The inner wall of the disc is fixedly connected to the outer wall of the bidirectional threaded rod. The slot is evenly and circumferentially formed on the outer wall of the disc. A locking block is fixedly connected to the outer wall of the fixing frame. The lever is disposed on the inner wall of the locking block.

[0009] Furthermore, a connecting block is fixedly connected to the outer wall of the fixing frame, the outer wall of the clamping rod is disposed on the inner wall of the connecting block, a spring is sleeved on the outer wall of the clamping rod, and one end of the spring is fixedly connected to the outer wall of the connecting block.

[0010] Furthermore, a motor is provided on the upper surface of the machine platform, and the output end of the motor is fixedly connected to the inner wall of the turntable.

[0013] Furthermore, a camera is installed on the outer wall of the support frame, and an electric rotating rod is fixedly connected to the upper surface of the machine platform. The electric rotating rod is located between the outer ring outlet and the second inlet of the conveyor belt.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the bidirectional threaded rod is driven to rotate by rotating the handwheel, which drives the two moving frames on both sides to move synchronously in opposite directions along the guide rod, thereby quickly adjusting the horizontal position of the conveyor belt. The operator can flexibly adjust the spacing of the conveyor belt according to the size characteristics of different batches of silkworm cocoons, ensuring that the silkworm cocoons are safely transferred to the screening station. The structure is stable and reliable, significantly improving the adaptability of the equipment to silkworm cocoons of different specifications.

[0015] 2. In this utility model, based on the quality signal of silkworm cocoons identified by the camera, the electric telescopic rod is controlled to push the guide plate to rotate around the connecting rod, and its tilt angle is dynamically adjusted. Qualified silkworm cocoons slide into the main collection box on one side along the guide plate, while defective products are guided to the secondary collection box on the other side. This sorting action is linked with the conveyor belt's conveying rhythm to achieve fully automatic and accurate diversion. The screening process does not require manual intervention, which greatly reduces the missed detection rate and the misjudgment rate, and effectively improves the sorting efficiency.
