Automatic packing machine

Abstract

The invention discloses an automatic packing machine. The automatic packing machine comprises a rack and further comprises a bag opening device, a detection mechanism, a clamping platform, a conveyingtrolley, a cam driving mechanism, a vertical sealing mechanism, a bottom sealing mechanism, a bag cutting mechanism, a filling mechanism, a top sealing mechanism and a receiving mechanism which are arranged on the rack. The conveying trolley clamps a packing bag and transfers the packing bag to the middle, corresponding to the position of the processing station, of the clamping platform. The bagopening device is arranged on one side of the clamping platform and used for opening a bag opening of the packing bag. The clamping platform is arranged on the upper portion of the conveying trolley.Two parallelly-arranged clamping assemblies move oppositely to clamp the packing bag conveyed by the conveying trolley. The cam driving mechanism drives the bag opening device, the clamping platform,the conveying trolley, the vertical sealing mechanism, the bottom sealing mechanism, the filling mechanism, the top sealing mechanism and the receiving mechanism to work. The automatic packing machineis ingenious in structure and high in working efficiency, the bag opening device is suitable for bag opening of a three-combined bag, double bags, a single bag and a double-combined bag, and the rejection rate is low.

Description

technical field [0001] The invention relates to an automatic packaging machine. Background technique [0002] In the prior art, the working steps of the fully automatic packaging machine are as follows: Step 1, fold the plastic wide band in half to form a double-layer belt with the opening upward; Step 2, pass the folded double-layer plastic belt through a high-frequency heat press machine Press out two traces to form a conjoined bag; step 3, cut off the plastic bag on both sides of the hot-pressing trace; step 4, suck open the upward opening of the bag; step 5, fill the bag with Packing food; step 6, flatten the bag; step 7, high-frequency heat sealing; this kind of packaging machine is not high in production efficiency because it is a single package. At present, the success rate of bag opening of packaging machinery is low, and the situation of incomplete or unopened packaging bags often occurs, which affects subsequent processing. At present, the packaging machinery can...

[0002] In the prior art, the working steps of the fully automatic packaging machine are as follows: Step 1, fold the plastic wide band in half to form a double-layer belt with the opening upward; Step 2, pass the folded double-layer plastic belt through a high-frequency heat press machine Press out two traces to form a conjoined bag; step 3, cut off the plastic bag on both sides of the hot-pressing trace; step 4, suck open the upward opening of the bag; step 5, fill the bag with Packing food; step 6, flatten the bag; step 7, high-frequency heat sealing; this kind of packaging machine is not high in production efficiency because it is a single package

At present, the success rate of opening bags of packaging machinery is low, and the opening of packaging bags is often incomplete or unopened, which affects subsequent processing.

At present, the packaging machinery cannot detect whether the mouth of the packaging bag has been completely opened. When the packaging bag is not completely opened or the bag is not opened, the subsequent filling work will continue as usual, which will cause the filling liquid to leak on the rack On the other hand, it will cause damage to parts, cause serious waste, and increase production costs
