Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a double-layer conveying mechanism for a ton bag packaging machine. Background Art

[0002] The ton bag packaging machine is used to fill the ton bag with a certain amount of material and then vacuum and heat-seal the ton bag. The ton bag is transported to the loading position and vacuum position by a conveyor. The ton bag is directly placed on the conveyor for transportation. After the ton bag is transported to the bagging position, the buckle of the ton bag is hooked to load the material. After the bagging is completed, the buckle is released and the material is transported in time by relying on the conveying device.

[0003] Among them, the new type of hook translation mechanism of the ton bag packaging machine disclosed in application number CN202122411892.2 is also an increasingly mature technology. It solves the shortcomings of inconvenient hanging bag transportation in production, can improve the degree of automation of hanging bag transportation, and the conveying structure of the new type of ton bag packaging machine hook translation mechanism is reliable. When this mechanism is applied, a rodless cylinder that can save space can be used to drive the connecting plate to slide. When the connecting plate is driven to slide by the slide in the rodless cylinder, it can drive the slider in the linear guide rail to slide outside the track. The setting of the strip groove and the protrusion can improve the stability of the sliding of the connecting plate and the hook.

[0004] Based on this, I agree with the advantages of the above products, but there are still the following defects:

[0005] This translation mechanism requires workers to unload the packaging bags during use. Since the filled packaging bags are heavy, unloading the bags increases the workers' workload and reduces efficiency. Utility Model Content

[0006] The purpose of the utility model is to provide a double-layer conveying mechanism for a ton bag packaging machine, so as to solve the problem in the above background technology that the workload of the staff is increased when unloading the packaging bags.
