The two guide strips are distributed parallel to each other, and each guide strip has a strip-shaped hole in the middle. A set of cylinder output ends located on one side of the strip hole are fixedly connected to the other side of the strip-shaped carrier block. The ultrasonic welding module passes through the strip hole. The bag mouth clamping belt is located in the middle position between the two guide strips. The roller conveyor is arranged between two side support plates.

[0020] Please see Figure 1-3 As shown, an automatic packaging device for modified polypropylene includes guide plates 1, an ultrasonic welding module 210 located on one side of a strip-shaped carrier block 2, cylinders 3, a roller conveyor 7, and a bag mouth clamping belt 8. The two guide plates 1 are distributed parallel to each other, and each guide plate 1 has a strip-shaped hole 110 in the middle. The output end of a set of cylinders 3 located on one side of the strip-shaped carrier block 2 is fixedly connected to the other side of the strip-shaped carrier block 2. The ultrasonic welding module 210 passes through the strip-shaped hole 110. A portion of the bag mouth clamping belt 8 is located at the middle position between the two guide plates 1. The roller conveyor 7 is arranged between two side support plates 6.

[0021] The bag mouth clamping belt 8 is a closed loop, and the toothed surfaces on the inner side of the bag mouth clamping belt 8 are respectively meshed with two gears 9 distributed alternately. One side of one of the gears 9 is connected to an external motor, and the external motor drives the connected gear 9 to rotate, so that the bag mouth clamping belt 8 can be synchronized with the roller conveyor 7.

[0022] A pressing steel strip 10 extends into the inside of the bag opening clamping strap 8, and one end of the pressing steel strip 10 is fixedly installed at the top of the upright 11. By pressing down the pressing steel strip 10, the bag opening is wrapped together, and then the pressing steel strip 10 is released and springs back, so that the wrapped bag opening part enters the bag opening clamping strap 8, preventing the bag opening from loosening and ensuring the state of being sealed.

[0023] Furthermore, the guide plate 1 is fixedly connected to the top of the side support plate 6 via symmetrically distributed connecting rods.

[0024] Furthermore, the cylinders 3 are in groups of two, and the cylinder bodies of the two cylinders 3 in the same group are mounted on the same strip plate 4, with both ends of the strip plate 4 fixedly connected to the guide strip plate 1.

[0025] Furthermore, the bottom edge of the guide strip 1 is connected to a bag body side baffle 5.

[0026] Furthermore, the ultrasonic welding module 210 is connected to an external ultrasonic generator.

[0027] Working principle: The opening of the modified polypropylene packaging bag is reset by the pressing steel strip 10 and pressed into the bag opening clamping belt 8. At this time, the bag opening clamping belt 8 and the roller conveyor 7 are running synchronously. After the bag opening is moved between the two ultrasonic welding modules 210, the two sets of cylinders 3 extend synchronously, causing the two connected ultrasonic welding modules 210 to move inward, first pressing the bag opening together, and then starting the ultrasonic welding module 210 to perform ultrasonic welding, completing the automatic sealing task.

[0028] Compared with existing technologies, the difference lies in the following: by pressing down the steel bar 10 to wrap the bag opening together, and then releasing the steel bar 10 to allow the wrapped bag opening part to enter the bag opening clamping belt 8, the bag opening is prevented from loosening and the sealing state is guaranteed. At the same time, the roller conveyor 7 and the bag opening clamping belt 8 are in a synchronous running state, which is conducive to sending the bag body with the bag opening bound to the sealing position. The two symmetrically distributed bag body side baffles 5 play a role in supporting the side of the bag body, further improving the regularity of the bag opening related parts.
