[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Please see Figure 1-4 An automatic bagging and sewing machine for plastic woven bags includes a mounting frame 1, and a feeding and placing mechanism is provided on the left side wall of the mounting frame 1.

[0022] The material placement mechanism includes two mounting plates 2 fixedly connected to the lower end of the left side wall of the mounting frame 1 and distributed front to back. A first rotating shaft 3 is rotatably connected between the two mounting plates 2. Two rotating plates 4 distributed front to back are fixedly connected to the outer wall of the first rotating shaft 3. An electric telescopic rod 5 is rotatably connected between the upper end of the left side wall of the mounting frame 1 and the two rotating plates 4 through a hinge seat. The opposite side walls of the two rotating plates 4 are provided with mutually matching fixing mechanisms.

[0023] In this embodiment: when feeding the woven bag roll, two electric telescopic rods 5 are activated to extend them. These rods drive two rotating plates 4 to rotate downwards around the first rotating shaft 3 until they reach a horizontal position. This lowers the position of the fixing mechanism, and the woven bag roll is then moved between the two rotating plates 4. The fixing mechanism then secures the woven bag roll. After securing, the two electric telescopic rods 5 retract, lifting the two rotating plates 4 and the fixed woven bag roll. The automatically lifting woven bag roll placement rack facilitates easy and convenient feeding of the woven bag roll without the need for additional lifting equipment, making it convenient to use.

[0024] As a technical optimization of this utility model, the fixing mechanism includes a second rotating shaft 6 rotatably connected to the opposite side wall of the two rotating plates 4, a limiting disk 7 is slidably connected to the outer wall of each of the two second rotating shafts 6, and a plurality of fixed plates 8 are slidably connected to the opposite side wall of each of the two limiting disks 7.

[0025] In this embodiment: when fixing the woven bag roll, the two limiting discs 7 are pushed to move in opposite directions. The two limiting discs 7 drive the two sets of fixing plates 8 into the interior of the woven bag roll. Then the two sets of fixing plates 8 move in opposite directions, so that the outer walls of the two sets of fixing plates 8 abut against the inner wall of the woven bag roll, thereby fixing the woven bag roll.

[0026] As a technical optimization of this utility model, multiple arrayed sliding grooves 9 are provided on the opposite side walls of the two limiting disks 7, and sliders 10 matching the sliding grooves 9 are fixedly connected to the opposite ends of the two sets of fixing plates 8. Sliding rods 11 that are slidably connected to the sliders 10 are fixedly connected inside the multiple sliding grooves 9.

[0027] In this embodiment, the cooperation between the slide groove 9, the slider 10 and the slide rod 11 can limit the position of the fixed plate 8, so that the fixed plate 8 can move smoothly.

[0028] As a technical optimization of this utility model, multiple fixing plates 8 located on the same side are grouped together. The opposite side wall of two groups of fixing plates 8 and the end near the limiting plate 7 are both set as inclined structures. The other ends of the two second rotating shafts 6 are fixedly connected with inclined limiting blocks 12 that match the inclined structures.

[0029] In this embodiment: During the movement of the two limiting discs 7 and the two sets of fixed plates 8, the position of the inclined limiting block 12 remains unchanged. When the inclined structure set on the opposite side wall of the two sets of fixed plates 8 moves to the two inclined limiting blocks 12, the two sets of fixed plates 8 can be pushed to move in opposite directions through the mutual cooperation between the inclined structure and the inclined limiting block 12.

[0030] As a technical optimization of this utility model, an extension cylinder 13 sleeved on the outer wall of the two opposing side walls of the two limiting discs 7 is fixedly connected, and a fixing bolt 14 is threaded through the outer wall of the extension cylinder 13.

[0031] In this embodiment, the position of the limiting plate 7 can be fixed by the cooperation between the extension tube 13 and the fixing bolt 14.

[0032] As a technical optimization of this utility model, the outer wall of the slide bar 11 is fitted with a spring 15 located between the slider 10 and the slide groove 9.

[0033] In this embodiment: when the two sets of fixing plates 8 move and reset in opposite directions, multiple springs 15 can push the two sets of fixing plates 8 to move and reset in opposite directions.

[0034] The working principle and usage process of this utility model are as follows: When feeding the woven bag roll, the two electric telescopic rods 5 are activated to extend them. These rods drive the two rotating plates 4 to rotate downwards around the first rotating shaft 3 until they reach a horizontal position. This lowers the position of the fixing mechanism. The woven bag roll is then moved between the two rotating plates 4 and fixed by the fixing mechanism. Specifically, the two limiting discs 7 are pushed to move in opposite directions, causing the two sets of fixing plates 8 to enter the woven bag roll. During the operation, the position of the inclined limit block 12 remains unchanged. When the inclined structure set on the opposite side wall of the two sets of fixing plates 8 moves to the two inclined limit blocks 12, the two sets of fixing plates 8 can be pushed to move in opposite directions through the mutual cooperation between the inclined structure and the inclined limit block 12, so that the outer wall of the two sets of fixing plates 8 abuts against the inner wall of the woven bag roll, thereby fixing the woven bag roll. After the fixing is completed, the two electric telescopic rods 5 retract, and the two electric telescopic rods 5 drive the two rotating plates 4 and the fixed woven bag roll to be lifted. Then, the woven bag roll is easily and conveniently loaded through the automatically lifting woven bag roll placement rack.
