Description

Technical Field

[0001] The utility model relates to the field of packaging equipment, in particular to an automatic weighing and packaging integrated machine for grain purchase. Background Art

[0002] After farmers harvest the grain, grain buyers will purchase the farmers' excess grain. When the grain is returned to the granary, it will be shelled, weighed and packaged.

[0003] When the grain is quantitatively weighed, the staff puts the packaging bag on the quantitative bagging mechanism and then takes the grain. After the grain is taken, the conveying device conveys the unsealed bagged grain to the packaging mechanism. However, when the bagged grain is moved, the staff needs to keep the bag opening aligned until one end of the bag begins to seal, which is troublesome and affects work efficiency.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, a conveying device, a turning frame, an adjusting motor and a clamping mechanism are arranged in a manner that cooperates with each other. When the quantitatively packaged grains fall onto the conveying device, the conveying device conveys the unsealed packaging bag to between the two clamping mechanisms. When the packaging bag moves between the two clamping mechanisms, the adjusting motor is started. At this time, the transmission shaft and the second bevel gear rotate. The rotating second bevel gear drives the first bevel gear and the double-headed threaded rod to rotate. The rotating double-headed threaded rod causes the two clamping mechanisms to approach each other until the clamping roller contacts the bag opening of the packaging bag. The rotating motor of the clamping mechanism drives the clamping roller to rotate. The rotating clamping roller generates an upward movement tendency for the bag opening of the packaging bag, thereby aligning the bag opening of the packaging bag until the packaging mechanism completes the sealing of the packaging bag. Since there is no need to manually adjust the position of the bag opening during the sealing process, the work efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS
