Description

Technical Field

[0001] The utility model relates to the technical field of powder pesticide packaging, in particular to an anti-escape powder pesticide quantitative packaging machine. Background Art

[0002] Powder packaging machine is suitable for quantitative packaging of powdery, powdery and powdery materials in chemical, food, agricultural and sideline products and other industries.

[0003] When the existing powder quantitative packaging machine is packaging, the bag mouth of the packaging bag is generally fixed on the outer periphery of the discharge port of the quantitative material barrel before the material is discharged. However, for pesticide powder, the content of each packaged bag is relatively small, the sub-packaging bag is small, and the material is relatively hard. It is not convenient to fix it on the discharge port of the quantitative material barrel, and it is easy to form a large gap with the edge of the discharge port. When the discharge port of the quantitative material barrel starts to discharge, the powder is higher than the bottom of the sub-packaging bag, which can easily cause the powder pesticide to be lifted up and overflow from the gap. This not only affects the environment of the packaging workshop, but also the workers inhale the lifted powder pesticide, which is easy to endanger their lives.

[0004] To this end, we propose an anti-escape powder pesticide quantitative packaging machine to solve the above problems. Utility Model Content

[0008] In a further embodiment, a polished rod is installed inside the mounting frame, the polished rod is parallel to the double-headed screw rod, and the polished rod passes through the interior of the screw sleeve and is slidably connected thereto.

[0009] In a further embodiment, the clamping plate is connected to the side plate of the U-shaped frame via a spring and a guide rod, and the guide rod runs through the inside of the side plate of the U-shaped frame.

[0010] In a further embodiment, a sliding block is provided on one side of the clamping plate close to the sleeve rod, and the sliding block is slidably inserted into a sliding groove on the surface of the U-shaped frame.

[0011] In a further embodiment, anti-slip pads are connected to opposite surfaces of the clamping plate.

[0012] In a further embodiment, the connecting rod is composed of two round rods which are sleeved together.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] When the two groups of clamping plates in the bag clamping mechanism of the utility model clamp the two corners of the bag opening of the packaging bag respectively, the double-headed screw is rotated to control the two screw sleeves to move closer to each other, thereby driving the two groups of clamping plates to move closer to each other, so as to squeeze the bag opening of the packaging bag open, and facilitate the discharge port of the quantitative packaging barrel to extend into the packaging bag. At the same time, when the gear is set to rotate, the sleeve rod is driven to rise, so that the discharge port of the quantitative packaging barrel can extend into the bottom of the packaging bag, so that when the packaging is unloaded, the sleeve rod drives the packaging bag to gradually descend as the powder in the bag increases, effectively avoiding the problem of dust caused by excessive height difference when the powder is unloaded.
