Technical Field

[0001] The invention relates to the field of packaging machinery, in particular to a vertical packaging bag bagging machine. Background Art

[0002] Vertical packaging machines generally work in a way of feeding from the top and sealing from the bottom, such as the Chinese utility model patent with publication number CN217730958U, which is named as a sheet material automatic packaging equipment. As shown in Figure 15, the sealing device is located below the bag body opening device, and a guide plate is arranged at the bottom of the sealing device. The inner surface of the guide plate forms an output channel. The sealing head is arranged at the upper entrance position of the guide plate. The sealing device is also provided with a bag body block for blocking the output channel. A through groove is arranged on the guide plate for the bag body block to be extended and retracted. The bag body block can be extended and retracted along the through groove inside and outside and can be adjusted up and down. The function of the bag body block is to support the bag body containing the material, and then the upper sealing head is sealed in the state where the bag body is supported. However, the bag body of this structure has a heavy material and the bag body itself is made of flexible material, so the bottom will be bent or even wrinkled. The bending or wrinkling of the bottom of the bag body will cause the bag mouth to deform. The uneven bag body or uneven bag mouth will lead to poor sealing quality, which will produce waste. Therefore, a vertical packaging bag bagging machine is urgently needed to solve the problem of poor sealing quality. Summary of the invention

Vertical packaging bag bagging machine, characterized by: The material conveying platform (2) comprises a working platform with a working plane, or the main body of the material conveying platform (2) is the working plane, a plug plate (11) with a power source is provided above the working plane, and a gap is provided on the working plane for the plug plate (11) to pass through; A plastic packaging bag silo (3) is provided on the side of the working plane, and a swing arm (4) with a suction nozzle (41) is provided below the silo (3). After the swing arm (4) swings, it sucks the packaging bag from the silo (3) to below the working plane, and finally makes the packaging bag in a vertical state. The suction nozzle (41) on the swing arm (4) cooperates with the suction nozzle (41) provided on the other side below the working plane to open the mouth of the plastic bag; A bag body clamping and moving device is also provided below the working plane. The bag body clamping and moving device is provided with a clamping plate (61) and a power source capable of closing or separating the clamping plate (61). The device is also provided with a power source capable of moving the clamping plate (61) up and down. When the clamping plate (61) rises to a high position, it clamps the plastic bag filled with materials, which is the first position at this moment. When the clamping plate (61) descends to a low position, the top bag opening of the plastic bag is located at the heat sealing head (71) of the heat sealing device (7), which is the second position at this moment. The clamping plate (61) shuttles in a clearance channel formed by the heat sealing head (71), and finally the plastic bag filled with materials is heat-sealed at the second position clamped by the clamping plate (61).

11. The vertical packaging bag bagging machine according to claim 10, characterized in that: At least one of the suction nozzle (41) on the swing arm (4) and the suction nozzle (41) on the other side has a power source for horizontal movement toward each other, which is used for the suction nozzles (41) on both sides to suck up plastic bags.

12. The vertical packaging bag bagging machine according to claim 10, characterized in that: The heat sealing head (71) has a power source for driving it to close or separate horizontally. The heat sealing device (7) also includes a retaining plate (72). The retaining plate (72) moves synchronously with the heat sealing head (71) to close, or moves toward the plastic bag earlier than the heat sealing head (71) during heat sealing. The retaining plate (72) has a clearance groove (721) in the middle for accommodating the clamping plate (61), so that when the heat sealing head (71) is closed, the retaining plate (72) and the clamping plate (61) are in contact with the outer surface of the plastic bag.

13. The vertical packaging bag bagging machine according to claim 12, characterized in that: The closed clamping plates (61) have different widths, wherein the heat sealing head (71) of the narrower clamping plate (61) extends into the clearance groove (721) of the retaining plate (72) when closed, and the narrower clamping plate (61) cooperates with the retaining plate (72) and the wider clamping plate (61) on the other side to clamp the plastic bag.

14. The vertical packaging bag bagging machine according to claim 10, characterized in that: A plurality of groups of swingable guide rods (5) are provided below the working plane. When two adjacent guide rods (5) are opened, they connect the gap and the bag opening to form a material feeding channel for the inserting plate (11) to smoothly insert the material into the bag body.

15. The vertical packaging bag bagging machine according to claim 14, characterized in that: The two adjacent guide rods (5) are in a V shape when closed, and when opened, the bottoms swing outwards to open the two sides of the plastic bag.

16. The vertical packaging bag bagging machine according to claim 10, characterized in that: The bag body clamping and moving device comprises a mounting seat (62), a crossbeam (63) is arranged on the mounting seat (62), a clamping plate (61) is fixed on the crossbeam (63), and the mounting seat (62) is connected to a power source for driving the mounting seat (62) to move up and down.

17. The vertical packaging bag bagging machine according to claim 10, characterized in that: A guide plate (81) is provided below the bag body clamping and moving device.

18. The vertical packaging bag bagging machine according to claim 10 or 17, characterized in that: A discharge conveyor belt (82) is provided below the bag body clamping and moving device.
