The conveyor belt conveying and the round belt pressing adopt the same power source; the height of the driven wheel of the round belt is manually adjusted (the lifting frame 30 and the conveying bracket 1 are slidably connected by the linear slider 19 and the driven linear slide rail 18, the conveying bracket 1 is rotatably installed with a lifting adjustment screw rod 20, and the top of the lifting adjustment screw rod 20 is installed with a second lifting adjustment hand wheel 31, and the lifting frame 30 is installed with a nut that cooperates with the lifting adjustment screw rod 20 to realize the lifting of the lifting frame 30), which can meet the compaction requirements of different numbers of portable folding paper bags, improve the practicality of the mechanism, and reduce the failure rate of the equipment;

[0029] like Figure 1-3 ; The conveying bracket 1 is located above the conveyor belt and is equipped with a tensioning wheel cantilever shaft and two bearing seats 9. The two bearing seats 9 are equipped with gears that mesh with each other. A cantilever driving shaft 10 is installed at one end of one of the bearing seats 9, and a driven sprocket 6 is provided on one side of the other bearing seat 9. The driven sprocket 6 and the driving sprocket 5 are connected by a chain; the cantilever driving shaft 10 is equipped with multiple driving wheels 11, and the tensioning wheel cantilever shaft is equipped with multiple tensioning wheels 14 corresponding to the driving sprocket 5; four driving wheels 11 and four tensioning wheels 14 are each provided, and four cantilever driven shafts 12 are provided, and the driven wheels 13 installed on the four cantilever driven shafts 12 are 4, 4, 3 and 2 respectively.

[0030] like Figure 3-6; A lifting frame 30 is adjustably installed on one side of the conveying bracket 1. The lifting frame 30 is located above the conveyor belt 4 and is equipped with multiple parallel cantilever driven shafts 12. The cantilever driven shaft 12 is equipped with multiple driven wheels 13. A round belt 15 is placed between the driven wheel 13 and the driving wheel 11; the portable folding paper bag enters the conveyor line from the entrance of the conveyor line, the driving roller of the round belt is located 150mm above the entrance of the conveyor line, and the end driven roller of the round belt is 45mm above the conveyor belt. The lower surface of the round belt naturally forms a trumpet shape that changes from high to low. When the folding paper bag is conveyed forward from the entrance, the bottom of the paper bag is above the conveyor belt, and the upper part of the paper bag is pressed by the round belt. As the folding paper bag is conveyed forward, the overall height of the paper bag decreases as the gap between the round belt and the bottom conveyor belt becomes smaller, thereby achieving the compaction effect of the portable folding paper bag.

[0031] like Figure 3-4 The lifting frame 30 and the conveying bracket 1 are slidably connected through a linear slider 19 and a driven linear slide rail 18. The conveying bracket 1 is rotatably installed with a lifting adjustment screw 20, and a second lifting adjustment handwheel 31 is installed on the top of the lifting adjustment screw 20. The lifting frame 30 is installed with a nut that cooperates with the lifting adjustment screw 20 to realize the lifting of the lifting frame 30.

The transition plate 17 prevents the folding paper bag from opening after passing through this empty section. After passing through this transition plate, the folding paper bag enters under the film-splitting triangular plate and is wrapped by the film. After the film is inserted, the portable folding paper bag cannot open freely, that is, a compacting and compacting effect is achieved.

[0033] The working principle of the utility model is as follows: a driving roller, a driving motor, an end driven roller and a conveying belt are installed on the conveying bracket. The driving motor drives the conveyor belt to convey. At the same time, two sets of bearing seats are designed on the front side plate of the conveying bracket. A driving gear is designed on the bearing seat. A transmission driven sprocket is designed on the left bearing seat, and the transmission driving sprocket on the driving shaft transmits the driving shaft power to the upper driving gear through a chain. A cantilevered driving shaft of a round belt is designed on the right bearing seat. The driving gear transmits the power of the lower conveyor belt to the round belt pulley, which can ensure that the speed of the conveyor belt and the round belt remains the same. The folding paper bag is prevented from being dislocated up and down during the transportation process; the front end of the round belt is designed with a cantilever driven shaft and driven wheel that can be adjusted up and down, and the gap between the driven wheel and the lower belt can be manually adjusted by lifting and adjusting the screw rod 20. This gap is the passing height of the folding paper bag between the conveyor belt and the round belt. A transition plate is designed at the gap between the film-splitting triangle plate and the driven wheel of the round belt to prevent the folding paper bag from expanding after passing through this empty section. After passing through this transition plate, the folding paper bag enters under the film-splitting triangle plate and is wrapped by the film. After being put into the film, the portable folding paper bag cannot expand freely, thus achieving a compacting and compacting effect.
