[0018] Through the above arrangement, the two bag-supporting plates can be opened and closed.

[0019] The utility model is further configured as follows: a bag supporting seat is fixed at the lower end of the rotating shaft, a screw hole is formed on the bag supporting seat, a connecting piece is fixed on the bag supporting plate, an adjustment groove is formed on the connecting piece, and a screw is provided to pass through the adjustment groove and connect with the screw hole on the bag supporting seat to realize the connection between the connecting piece and the bag supporting seat.

[0020] Through the above arrangement, the front and rear positions of the bag support seat can be adjusted, and combined with the adjusting screw, the various directions of the bag support plate can be adjusted.

[0021] The utility model is further configured as follows: upper edges of the two bag-supporting plates extend toward each other to form upper extension walls, lower edges of the two bag-supporting plates extend toward each other to form lower extension walls, and a placement groove is formed between the upper extension wall and the lower extension wall.

[0022] The arrangement of the placement slots can make the bag body more stable when opened, making it more convenient to put items into the bag body.

[0023] The utility model is further configured such that the height of the placement trough gradually increases in the opposite direction of the feeding direction.

DETAILED DESCRIPTION

[0033] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0034] An adjustable bag-supporting structure for a bagging machine includes two bearing seats 1, a rotating shaft 3 rotatably provided in a bearing 2 on the bearing seat 1, a bag-supporting plate 4 fixedly connected to the lower ends of the two rotating shafts 3, a rotating shaft driving device for driving the rotating shafts to rotate, and two fixed plates 5. A sliding rod 6 and an adjusting screw 7 are provided between the two fixed plates 5. Two adjusting blocks 8 are sleeved on the sliding rod 6 and the adjusting screw 7. An adjusting nut 9 is fixed in each of the two adjusting blocks 8. The adjusting nut 9 and the adjusting screw 7 are screwed together, and the adjusting block 8 is fixedly connected to the bearing seat 1. Through the above arrangement: the position of the adjusting block 8 is adjusted by rotating the adjusting screw 7, and then the bearing seat 1 and the adjusting block 8 are fixedly connected, thereby indirectly adjusting the distance between the two bearing seats 1, thereby achieving the advantage of adjusting the distance between the two bag-supporting plates 4.

[0035] The adjusting screw 7 is a bidirectional screw, comprising a left screw 10 and a right screw 11. The threads of the left and right screws 10 and 11 are in opposite directions. Rotation of the adjusting screw 7 drives the two adjusting nuts 9 toward or away from each other. With this arrangement, the two bag-opening plates 4 can be simultaneously moved toward or away from each other by rotating the adjusting screw 7, thereby facilitating adjustment of the spacing between the bag-opening plates 4.

[0036] The middle of the two fixing plates 5 are fixed with screw bearings 12, and the adjusting screw 7 is rotatably connected to the fixing plate 5 through the screw bearings 12. One end of the adjusting screw 7 extends out of the fixing plate 5 and is fixedly connected to the screw handle 13. Through the above arrangement, the adjusting screw can be rotated more conveniently.

[0037] The adjusting block 8 has a receiving groove 14 formed therein, and the adjusting nut 9 has a flat surface 15 formed at the bottom of the receiving groove 14. The flat surface 15 cooperates with the bottom of the receiving groove 14 and inhibits relative rotation between the adjusting nut 9 and the adjusting block 8. Through the above arrangement, relative rotation between the adjusting nut 9 and the adjusting block 8 is prevented, thereby enabling the adjusting nut 9 to move under the rotation of the adjusting screw 7.

[0038] Be provided with two slide bars 6, two slide bars 6 are horizontally arranged, and adjusting screw rod 7 is also horizontally arranged, and is arranged between two slide bars 6. By above arrangement, can make adjusting block 8 move more steadily on slide bar 6.

[0039] A copper sleeve 16 is provided between the adjusting block 8 and the sliding rod 6. By the provision of the copper sleeve 16, the sliding rod 6 and the adjusting block 8 can be protected.

[0040] The shaft drive device includes a drive cylinder 17, the rear end of the drive cylinder 17 is rotatably connected to the bearing seat 1, the front end of the drive cylinder 17 is rotatably connected to a connecting block 18, and the other end of the connecting block 18 is fixedly connected to the upper end of the shaft 3. Through the above arrangement, the two bag-supporting plates 4 can be opened and closed.

[0041] A bag support seat 19 is fixed to the lower end of the rotating shaft 3. The bag support seat 19 is formed with a screw hole 20. A connecting piece 20 is fixed to the bag support plate 4. The connecting piece 20 is formed with an adjustment slot 21. A screw is inserted through the adjustment slot 21 and connects with the screw hole 20 in the bag support seat 19 to connect the connecting piece 20 and the bag support seat 19. This arrangement allows the front-to-back position of the bag support seat to be adjusted. Combined with the adjustment screw 7, the bag support plate 4 can be adjusted in all directions.

[0042] The upper edges of the two bag-opening plates 4 extend toward each other to form upper extension walls 22, and the lower edges of the two bag-opening plates extend toward each other to form lower extension walls 23. A placement groove 24 is formed between the upper extension wall 22 and the lower extension wall 23. The placement groove can make the bag more stable and more convenient to put items into the bag.

[0043] The height of the placing groove 24 gradually increases towards the opposite direction of feeding. Through the above arrangement, it is more convenient to put the articles into the bag.

[0044] The invention has the characteristic of conveniently adjusting the distance between the two bag-supporting plates.

[0045] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
