Description

Technical Field

[0002] The packaging of products in bags requires manual removal of single-piece packaging bags and placing them in the use area. Traditional manual operations result in low production efficiency, affect the quality of product packaging, and increase labor costs. It is necessary to adopt an automated mechanical packaging method. In the prior art, product packaging usually uses automated bagging machines for weighing and bagging. The assembly line operation generally weighs the product into bags through a bagging machine, and then transports the bag body to a bag sealing machine through an assembly line. In actual use, there are many factors that affect the normal operation of the assembly line. For example, because the packaging bag body is made of soft material, the bag body will deform with the bag mouth of the flowing packaging bag during the transmission process, and the bag body will collapse and deform due to the gap between the products, causing the bag sealing machine to fail to seal effectively. The mechanical arm grabs the packaging bag out of place or cannot open the packaging bag in time when the bag is supported into the machine, which will cause the line to be stopped for rectification, resulting in low production efficiency, ineffective use of production equipment and reduced product quality.

At the same time, the controller controls the air pump station to stop sucking air to the second suction head and pumping pressure to the fourth cylinder 541 and the third cylinder 52, the bag body grabbing device 5 is reset, the controller controls the air pump station to inject and extract a stroke of air pressure into the second cylinder 421, the suction plate 42 and the matching plate 43 move towards each other, suck and clamp the packaging bag, and then move in the opposite direction to open the open end of the packaging bag, the controller controls the second motor 44 to travel a preset stroke, and transmits the packaging bag to the bottom of the bagging machine 3. The bagging machine's built-in sensor senses the packaging bag signal, clamps the upper edge of the packaging bag, and starts the bagging operation, and the controller controls the bag body fixing device 4 to reset.

[0052] During the automatic bagging process, the controller controls the air pump station to reciprocately inject and extract air into the seventh cylinder 661. The telescopic rod of the seventh cylinder 661 reciprocates to push and pull one end of the first lever 663. Through the lever principle, the other end of the first lever 663 drives the first bottom plate 665 to reciprocate up and down, so that the first bottom plate 665 reciprocates to beat the packaging bag, making the product filled in the packaging bag more compact. The bagging machine completes bagging and transmits a signal to the controller. The controller controls the air pump station to stop the reciprocating injection and extraction of air in the seventh cylinder 661. At the same time, the controller controls the air pump station to inject air into the fifth cylinder 64. One end of the third gallows 631 is pushed by the fifth cylinder The telescopic rod of 64 pushes the displacement, and through the lever principle, the other end of the third gallows 631 is pressed to the outer edge of the upper end of the packaging bag through the first clamping plate 635 and the second clamping plate 636. The two groups of symmetrically arranged first clamping plates 635 and second clamping plates 636 complete the fixation of the packaging bag. The controller controls the air pump station to inject air into the sixth cylinder 65 for a set stroke through the delay setting. The telescopic rod of the sixth cylinder 65 pushes one side of the two clamping assemblies 3, and the two clamping assemblies 63 transport the packaging bag to the top of the conveyor belt 2. At the same time, the controller controls the air pump station through the delay control to reset the vacuum devices of the fifth cylinder 64 and the sixth cylinder 65 in turn.

[0053] The fourth sensor detects the packaging bag signal and transmits the signal to the controller. The controller controls the air pump to pump air into the two first cylinders 18. The two first cylinders 18 respectively drive the first pressing wheel 15 and the second pressing wheel 16 to move toward each other to close the mouth assembly. At the same time, the controller controls the first motor to rotate a preset stroke. The transmission shaft of the first motor drives the two driving wheels 154 to rotate through the synchronous wheel 123, the second gear 122 and the first gear 121 in turn. Because the outer periphery of the driving wheel 154 and the outer periphery of each driven wheel 155 form a synchronous structure through the second belt 158, the belt group transmission drives the packaging bag to move forward. Because the closing of the mouth assembly is completed in the process of the packaging bag moving forward, the pressing of the upper end of the packaging bag is completed. When the first motor completes a preset stroke, the controller controls the air pump to inject air into the two first cylinders 18. The two first cylinders 18 respectively drive the first pressing wheel 15 and the second pressing wheel 16 to move in opposite directions to open the mouth assembly. The packaging bag enters the bag sealing machine through the transmission belt 2, and the cycle is repeated.
