The packaging bag 50 can be folded into rolls and arranged in series on the side of the pulling pulley 11, and its leading end is wound longitudinally downwards between the leading pulling pulley 11 and the auxiliary pulley 12, and one side of the open end is a pocket 51 , and equidistantly coat the pocket side with a sensing area 54 of appropriate size, so that it can be sensed by the photoelectric element when shifting;

Stretching bar 13 is placed in the appropriate position slightly below between the pulling pulley 11 and the auxiliary pulley 12, and is arranged in the same direction so that it penetrates into the pocket 51 of the packaging bag 50 to stretch the pocket 51 so that the two sides are not fit;

At least one pair of stretching elements 14 are in the shape of a hook at a proper distance below the stretching rod 13. One end is connected to the pull plate 142 and penetrates into the pocket 51, and it is stretched to an appropriate opening. The other end is passed through a On the bracket 141, it can be fixed by positioning bolts 143 and the length between them can be adjusted to control the opening size of the pocket 51;

The conveyor belt 20 is arranged horizontally on the bag opening 51 side of the packaging bag 50;

The push rod 21, corresponding to the mouth 51 of the packaging bag 50, is controlled by a sensing element 22 and can be moved back and forth;

A pair of first heat-sealing elements 31 are horizontally arranged on both sides of the packaging bag 50, slightly lower than the proper position of the conveyor belt 20, and are respectively driven by a pair of first cylinders 30 to reciprocate in opposite directions synchronously to move the packaging bag. 50-side sealing, and the first cylinder 30 is activated by the control of the photoelectric element 101 or the length sensor 80;

A pair of positioning elements 33, located at a proper distance below the first heat-sealing element 31, have a distance that can just pass through the bag body that has been filled with packaging, and the distance is adjustable;

A pair of second heat-sealing elements 41 are longitudinally arranged on both sides of the bag opening 51 of the packaging bag 50 at an appropriate distance, and are respectively subjected to a pair of second cylinders 40 to reciprocate in opposite directions synchronously;

The cutting device includes a cutting knife 71 and a support element 72, which are respectively arranged on both sides of the packaging bag 50 at a proper distance below the first heat-sealing element 31, and are respectively moved back and forth synchronously by a pair of third cylinders 73. Position, cut off the packaging part of the heat-sealed packaging bag, so that the material can be cut to complete the operation.

As shown in Fig. 3 and Fig. 4, when the packaging bag 50 is moved downward by the pulling wheel 11 and the auxiliary wheel 12, that is, the length sensor 80 is driven to the expected set length distance at the same time, and then the control The motor 10 and the pulling pulley 11 pause their action, and after the packaging bag 50 passes between the pulling pulley 11 and the auxiliary pulley 12, its two sides are separated and opened by the stretching rod 13, and continue to be stretched by the stretching element 14 on the stretched side. When the bag opening 51 reaches the required size, after the packaging bag 50 is shifted to the expected length, the length sensor 80 controls the pulling wheel 11 to stop shifting, and at the same time makes the packaging 50 stop moving forward synchronously. The device 80 activates the first air cylinder 30 to drive the first heat-sealing element 31 to carry out lateral edge sealing 52 on the lower port of the packaging bag 50, and then, when the conveyor belt 20 transports the packaging 60 to the side pocket opening 51 of the packaging bag 50, it is received by the The blocking element 23 at this place blocks and stays there, and then the sensing element 22 at the corresponding position receives the signal, and then drives the push rod 21 to push the package 60 into the packaging bag 50; (the sensing element 3 can be an infrared ray sensor or other similar sensor).

At the same time as the push rod 21 returns, the first cylinder 30 also drives a pair of first heat-sealing elements 31 to move away from the packaging bag 50 for positioning. At this time, after the time delay of the length sensor 80 is terminated, the length sensor The device 80 controls the motor 10 to drive the pulling pulley 11 again, and the pulling bag 50 continues to move downward for another preset stroke, which is still just the preset length of the length sensor 80, and then the measuring device 80 controls the motor Pause the action, and at the same time, the first air cylinder 30 is still driving the first heat-sealing element 31 to perform horizontal edge sealing 52 on the packaging bag 50 above the packaging object 60, and the packaging bag 50 with the packaging object installed thereunder is positioned by the positioning element 33 Support, and can not shake phenomenon, to this moment, packaging bag 50 has all heat-sealed respectively at the upper and lower ends of packaging bag object 60 fixed distance and has completed.

At the same time, the second stop element 90 is also controlled by this element to make a rotational positioning of about 90 degrees. , so that another packaged object 60 can continue to move forward, and at the same time also block the third packaged object 60 to stop there, to cooperate with the downward movement of the packaging bag 50; that is, as long as one packaged object 60 passes through the second stop The distance between the stopper element and the first stopper element 23 is just that the packaging bag 50 moves down a unit stroke length, and once the second stopper element 90 has passed a set period of time and still does not have the object to be packaged 60 to advance to this position , that is, the sensor on the second stop element 90 automatically turns off all power sources, so that all elements stop moving, avoiding that the packaging bag 50 is always moved downwards, which hinders the subsequent packaging action. After a packaged object 60 is preset on the second blocking element 90, the power supply is turned on again manually.

The length sensor 80 and the photoelectric element 101 can be implemented at the same time or by choice. If they are installed in parallel at the same time, one of the elements can be used to control it at ordinary times, and the other is in a standby state. Once a failure occurs, the other immediately Replace, and detect or correct each other at the same time, to increase the accuracy and reliability of the utility model operation.

As shown in Figure 6, the above-mentioned first heat-sealing element 31 can also be heat-sealed, and the cutter is designed in an integrated manner, so that the upper and lower ends of the cutter have heat-sealed parts, as shown in Figure 7, so that after heat-sealing, it can Carry out cutting action simultaneously, like this, just can omit the member such as the 3rd air cylinder 73 and cutting knife 71, supporting element 72, makes the utility model more simplified, and does not affect original expected effect.
