Description

Technical Field

[0001] The utility model relates to the technical field of bottled rejection equipment, in particular to a device for rejecting bottled caps with cracked lines. Background Art

[0002] Capping machines are used in the production of bottled products to mechanically tighten the caps. However, this equipment is subject to machining errors due to the imperfect cylindrical shape of the bottled products. According to statistics, approximately one in a thousand bottled products have skewed or loose caps that are too high. These crooked and high caps not only affect the overall aesthetics of the product but also expose the bottle contents to air, leading to deterioration or leakage. The capping machines we currently use have a built-in cracked cap rejection function. However, due to their simplistic design, the probability of cracked caps being rejected depends entirely on the crack's orientation. The remaining cracked caps will still pass through the heat sealer to the outer packaging line. Due to the cracked caps, the sealer cannot fully seal the laminated film on the bottle's opening. If operators fail to detect and remove these cracked caps promptly, the cracked caps are likely to be packaged and stored, potentially leading to customer complaints and extensive manual repackaging.

[0003] Prior art application number 201620545517.3 discloses a bottle cap detection and rejection device, which discloses an automatic detection and rejection device for crooked or high caps. The key technical features of the device include: a baffle, a photoelectric probe, a controller, a converter, a trigger, and a push rod. The baffle includes a fixed component, a rotating shaft, and a movable component connected in sequence. A gap is formed between the movable component and the top cap of the goods to be inspected. The push rod's telescopic opening faces the goods to be inspected, which are brought to the bottom of the movable component by a guide rail. The photoelectric probe is used to sense the upward movement of the movable component. The signal from the photoelectric probe is transmitted to the controller via the converter, and the controller controls the start and stop of the blower via a solenoid valve. The device has the beneficial effect of amplifying the height difference between crooked or high capped bottled products and qualified bottled products by using a pressure plate. The photoelectric probe is used for detection, which greatly improves the detection accuracy. When a crooked or high capped bottled product is detected, the push rod extends to push it off the guide rail, achieving automatic detection and rejection, saving labor costs. However, the rejection accuracy is low, the movement rate is slow, and the rejection force cannot be adjusted. Utility Model Content
