[0022] When in use, the packaging bag to be pressed is placed on the upper surface of the conveyor belt 15, and then the motor 13 is turned on to rotate the conveyor roller 14 connected to its output end, and then the rotation of the conveyor roller 14 is used to realize the movement of the conveyor belt 15, so as to facilitate the subsequent horizontal conveyance of the packaging bag.

[0023] As a further implementation of this embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, a supporting leg 2 is fixedly installed at the top corner of the base 1, and the other end of the supporting leg 2 is fixedly connected to a top beam 3, a cylinder 4 is fixedly installed at the middle of the top of the top beam 3, and the bottom of the cylinder 4 is fixedly connected to a lifting seat 5, a pressing head 6 is fixedly installed at the middle of the bottom end of the lifting seat 5, a lower pressing seat 7 is distributed on one side of the pressing head 6, and a pressing roller 8 is rotatably connected to the inner side of the bottom of the lower pressing seat 7, the lower pressing seat 7 is slidably connected to the lifting seat 5 through a guide rod 9, and the lower pressing seat 7 is symmetrically distributed along the vertical center line of the lifting seat 5, a guide rod 9 is fixedly installed on the top of the lower pressing seat 7, and a limiting block 10 is fixedly installed on the other end of the guide rod 9, and a first spring 11 is sleeved on the outer surface of the guide rod 9, and a conveying structure is distributed on one side of the supporting leg 2;

[0024] When the packaging bag needs to be installed, the cylinder 4 works to push the lifting seat 5 fixed to its bottom longitudinally, and then the lifting seat 5 moves longitudinally to drive the pressing head 6 to move longitudinally, which is convenient for the subsequent use of the pressing head 6 to press the packaging bag. At the same time, when the lifting seat 5 moves longitudinally, it will push the lower pressing seat 7 through the first spring 11 arranged at its bottom, so that the lower pressing seat 7 can contact the packaging bag through the pressing roller 8 connected to the inner side of its bottom, thereby pressing and limiting the packaging bag.

[0027] Specific working principle:

[0028] When in use, the packaging bag to be pressed is placed on the upper surface of the conveyor belt 15, and then the motor 13 works to rotate the conveying roller 14 connected to its output end, and then the rotation of the conveying roller 14 is used to realize the movement of the conveyor belt 15, which is convenient for the subsequent horizontal transportation of the packaging bag. Then the cylinder 4 works to longitudinally push the lifting seat 5 fixed to its bottom, and then the longitudinal movement of the lifting seat 5 drives the pressing head 6 to move longitudinally, which is convenient for the subsequent use of the pressing head 6 to press the packaging bag. At the same time, when the lifting seat 5 moves longitudinally, it will push the lower pressing seat 7 through the first spring 11 set at its bottom, so that the lower pressing seat 7 contacts the packaging bag through the pressing roller 8 connected to the inner side of its bottom, thereby pressing and limiting the packaging bag, and then the lower pressing seat 7 is subjected to the reverse force It will push the guide rod 9, and then the first spring 11 sleeved on the outer side of the upper and lower ends of the guide rod 9 will deform and generate a reverse force, so that the lower pressure seat 7 can better press and limit the packaging bag, ensuring the stability of the packaging bag during the subsequent pressing process. When the packaging bag is pressed and the conveyor belt 15 is pressed down, the conveyor belt 15 will press down the buffer plate 19 distributed at its bottom, and then the buffer plate 19 slides with the guide block 17 provided on the inner wall of the support seat 16 through the guide groove 21 opened on its side wall. At the same time, the buffer plate 19 will squeeze the second spring 18 and the damper 20 during the longitudinal movement. The reverse force generated by the combination of the deformation of the two can achieve the purpose of buffering protection, thereby providing a simple support effect for the conveyor belt 15, which is convenient for the subsequent better pressing of the packaging bag.
