Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to an adjustable plastic box cover buckle device. Background Art

[0002] As we all know, in the face of diverse, fast and changing market demands, it is an inevitable trend to realize automated assembly line production of products. In the food, feed and other industries, materials need to be weighed, fed and canned. During canning, vacuum sealing or direct pressing and capping are used to seal the cans. However, the current direct pressing and capping methods are mostly achieved manually, which increases labor intensity, high cost and low efficiency on the one hand, and increases the probability of secondary pollution and poor safety on the other hand. In the traditional packaging production process, the capping and pressing processes are all completed manually by workers, with high labor costs, low production efficiency and labor-intensive work. Currently, common filling and sealing machines usually include filling devices and sealing devices.

[0003] The existing adjustable plastic box cover snapping device includes a cover snapping assembly, which includes a pressure plate and a cover pressing part. The pressure plate and the cover pressing part of the existing adjustable plastic box cover snapping device are fixedly arranged, and the inclination angles of the pressure plate and the cover pressing part are fixed. As the use time increases, the cover pressing part will be worn, and the downward pressure of the cover pressing body under the cover pressing part will be weakened, resulting in the cover being loose. The existing adjustable plastic box cover snapping device can only adjust the cover pressing part by adjusting the elastic force of the spring, and the effect is not good. Utility Model Content
