In normal transportation, the second slot 433 is connected to the first slot 432. After the clamping block 431 releases the pull head, the pull head reaches the right end of the first slot 432 and is jammed by the left end of the second slot 433, so that the pull head moves a distance on the chain, thereby making the two chains mesh to verify whether the connection between the pull head and the chain is stable and qualified. Afterwards, the lifting block and the second slot 433 descend so that the pull head moves to the right with the document bag and the chain. It should be noted that the fourth connecting plate 606 has an inclined plate at the notch position. The inclined plate is located on the right side of the lifting block and gradually rises from left to right to facilitate the free movement of the pull head and prevent jamming.

[0048] It also includes a pre-bending assembly 500, which includes a first bending roller 510 and a second bending roller 520. Both the first bending roller 510 and the second bending roller 520 are equipped with rollers. The length of the roller installed on the first bending roller 510 is shorter than the length of the roller installed on the second bending roller 520, and the relative position of the first bending roller 510 is lower than that of the second bending roller 520. The upper surface of the roller on the second bending roller 520 is close to the center line of the die 310.

[0049] like Figure 1 As shown, a second bending roller 520 is provided on the left side of the mold 310. The second bending roller 520 is rotatably connected to the mounting frame 100, and also includes a first bending roller 510. Figure 1 Not shown in the image, such as Figure 2 As shown, the first bending roller 510 is positioned lower horizontally relative to the second bending roller 520. The length of the roller installed on the first bending roller 510 is shorter than the length of the roller installed on the second bending roller 520. It can be understood that if the width of the document bag material laid flat is 40cm, then the length of the first bending roller 510 is 36cm and the length of the second bending roller 520 is 44cm. It should be noted that, taking the mold 310 in this embodiment as an example, the line connecting the midpoints of the vertical height of the mold 310 is its midpoint. The upper surface of the second bending roller 520 is located at ±2mm of the midpoint of the mold 310, so that the document bag has the same tension and consistent force when it is on the mold 310.

[0050] It also includes a first support wheel 601 and a second support wheel 602 disposed opposite to each other at one end of the mold 310, wherein the outer edge thickness of the second support wheel 602 is no more than 5mm. Figure 2 and Figure 3 As shown, a T-shaped structure is connected to the right side of the mold 310. A first support wheel 601 is rotatably connected to the upper side of the T-shaped structure, and a second support wheel 602 is rotatably connected to the lower side. Figure 3As shown, the first supporting wheel 601 has a larger outer wheel edge thickness than the second supporting wheel 602, and the outer wheel edge thickness of the second supporting wheel 602 is 2 mm, so as to form creases on the file bag, and the outer wheel edge thickness of the first supporting wheel 601 is 7 mm.

[0051] In another embodiment, a waste recycling mechanism is further included, such as Figure 4 As shown, the waste pipe is connected to the suction fan at one end and extends out of the outer side of the extension output die 310 at the other end, so as to directly suck the waste in the waste pipe out.

[0052] In a specific implementation, the flat file bag material enters from the lower side of the first bending rod, and since the width of the first bending rod is smaller than the width of the file bag material, the edges naturally form two creases. Then, the flat file bag material enters onto the upper surface of the first bending rod and moves to the right to the lower side of the die 310. The first bending rod gives the file bag material an upward force, so that the creases of the two edges are more obvious. After the file bag material enters the lower side of the die 310, the creases on both sides facilitate the formation of the enclosed shape. Then, the artificial operation passes the chain belt at the right end of the file bag material through the closed base 321. The file bag on the right side of the closed base 321 is engaged by the chain belt to form a closed state surrounding the die 310, and the left side is in an open state. At this time, the file bag on the left side forms a good surrounding shape. Then, the engaged chain belt enters the directional transportation groove 301 and moves to the right. The punch gun 335 cooperates with the punch port 332 to punch a break on the engaged chain belt. The enclosed file bag material continues to move to the right. The cylinder drives the positioning fork 410 to adhere to the outer surface of the file bag material. The inner wall of the groove chamber of the positioning fork 410 is in sliding connection with the chain teeth of the chain belt. The positioning fork 410 does not limit the left and right movement of the file bag. The break punched by the punch gun 335 is located to the right of the positioning fork 410, which is still on the directional transportation groove 301, i.e., on the second connecting plate 604. Then, the vertical cylinder drives the sub-control cylinder downward. The elastic rubber block at the lower side of the mechanical claw 442 clamps the file bag material together with the receiving block 441. The mechanical claw 442 moves away from each other to give the chain belt an outward force. The cylinder drives the broken tooth plate 420 upward into the directional transportation groove 301. At this time, the broken tooth plate 420 is upward from the break of the chain belt. The broken tooth plate 420 breaks the break by itself, so that one end of the break is disengaged. Meanwhile, the cylinder of the material conveying part 220 drives the material conveying block to the right. The second rod body 222 pushes the pull head into the first slot 432 of the clamping block 431. The cylinder of the butt joint base 434 drives the clamping block 431 to clamp the pull head. Then, the butt joint base 434 moves upward. The first slot 432 is in butt joint with the directional transportation groove 301. The chain belt enters the pull head, so that the installation of the pull head and the chain belt is completed. Then, the clamping block 431 moves away from each other to release the pull head. The pull head is clamped to the left end of the second slot 433 following the file bag to the right. At this time, the second slot 433 is lowered, so that the pull head can move to the right. Then, the installation of the next round is completed.

[0053] It should be emphasized that the embodiments of the present application are illustrative only and are not restrictive, and therefore the present application is not limited to the embodiments described in the specific embodiments, and any other embodiments derived by those skilled in the art according to the technical solutions of the present application also belong to the scope of protection of the present application.
