Description

Technical Field

[0001] The utility model belongs to the technical field of conveying equipment, and particularly relates to a lifting device and a packaging machine. Background Art

[0002] A Z-shaped elevator is a mechanical device used to transport materials. Its structure is in the shape of a letter Z, including a lower transverse section, a vertical section, and an upper transverse section. A Z-shaped elevator usually includes an annular conveyor chain and a feed hopper connected to it. During transportation, the conveyor chain can transport the material from the lower transverse section to the feed hopper to the upper transverse section, and then discharge it through the lower hopper on the lower transverse section.

[0003] Z-shaped elevators are suitable for conveying various powdered and granular materials and are widely used in industries such as seed selection, grain processing, feed, chemicals, hardware and electrical materials. However, many materials may be mixed with dust and other impurities during their natural growth or processing. For example, Chinese medicinal materials may also produce debris and other impurities due to friction and collision during the conveying process. These impurities are large in number and light in weight, making them difficult to remove. This not only affects the working environment, but also the quality of the final product.

[0004] Based on this, the applicant considered designing a lifting device and a packaging machine for removing impurities. Utility Model Content
