The lifting rod 15 is a rectangular rod body, and the lowering unit 16 is movably arranged on the lifting rod 15. It is supported by the base 11 and can move the packaged rolled fiber cloth through the conveyor belt body 12. The lowering unit 16 is driven to move by the first driving slide rail and with the help of the slide 13 and the lifting rod 15 to limit the position, the lowering unit 16 is prompted to rise and fall synchronously during movement.

[0045] As a preferred solution, further, the pair of pad arms 7 are both L-shaped, one end of the pair of pad arms 7 is symmetrically arranged on the pad platform 6, and the other end of the pad arm 7 is opposite to the folding arm 22 for installing the cutting unit 3.

[0046] As a preferred solution, further, the upper walls of the pad 6 and the pad arm 7 can be in contact with the second electric heating plate 33 and the cutter 36 .

[0047] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0048] S1. The equipment is stably placed on the base 11. After the equipment is powered on, the first electric slide rail 14 in the lower structure 1 is driven to drive the lifting rod 15 to move left and right. With the help of the guide roller 166 in the lowering unit 16, the force is applied within the inclined slide 13, so that the sleeve 161 can be moved up and down on the lifting rod 15 with translation to adjust the height. The packaging plastic film is rolled onto the roller 164 and fixed with the nut 165. The plastic film is then moved above the supporting platform 4 with the help of the limit of the slide 13. The first motor 163 in the chassis 162 is then driven to drive the roller 164 to rotate, and the plastic film is rotated and lowered to a certain length.

[0049] S2. Next, the folding assembly 2 is driven to flip the folding arm 22 relative to each other, causing the pickup unit 8 on the folding arm 22 to face the plastic film. Using the image from the camera 83, the flipping angle of the folding arm 22 is controlled, and the second electric slide rail 81 is driven to raise and lower the mechanical gripper body 82. The mechanical gripper body 82 grips the lower end of the plastic film. As the folding arm 22 flips and resets, the plastic film is pulled, causing the plastic film to cover the folding arm 22 and the drag-and-drop mechanism 5 on the left side of the folding frame 21.

[0050] S3 then moves the plastic film to the right, and lowers it to a certain length, causing the plastic film to cover the carrier 4;

[0051] S4. By driving the cutting unit 3 at the left end of the folding assembly 2, the first hydraulic cylinder 35 contracts, and the movable seat 34 drives the flip arm 32 to flip on the vertical rod 31, causing the second electric heating plate 33 and the cutter 36 to be positioned below the folding arm 22. This opens the opening at the left end of the folding arm 22, facilitating the placement of the cloth roll onto the drag-and-drop structure 5 between the folding arms 22 at the left end of the folding assembly 2, with the cloth roll positioned above the pulled plastic film. The flip arm 32 and the cutter 36 are then reset.

[0052] S5. At this time, the cloth roller is limited between the symmetrically arranged supporting rollers 54 and cannot move forward or backward; and according to the diameter of the cloth roller, the second hydraulic cylinder 55 is driven to retract and retract. With the active connection between the second hydraulic cylinder 55 and the linkage shaft 53, the swing arm 52 is driven to flip on the mounting rod 51, adjusting the relative tilt angle and spacing of the supporting rollers 54;

[0053] S6. Then, by driving the second motor 25 in the folding assembly 2, the second motor 25 drives one of the first driving arms 27 to rotate, and the two first driving arms 27 are connected in reverse symmetry through the second driving arm 28, forming an effect similar to a crankshaft, which can drive the two linkage arms 26 to push and pull the folding arms 22 on the folding frame 21 to achieve relative flipping; and then, through the relative movement of the drag-and-drop structure 5, the cloth roller is driven to flip and clamp on the supporting platform 4, and at the same time, the flipping, folding and laminating of the plastic film are achieved, and the first electric heating plate 23 and the second electric heating plate 33 form a door-shaped frame to clamp the plastic film on the pad 6 and the pad arm 7. Because the folding arms 22 on the left and right sides of the folding frame 21 are staggered and cannot achieve flipping and laminating, the pad arm 7 and the pad 6 are used to dock and clamp one pair of folding arms 22;

[0054] S7. After clamping, the front and rear sides and the top of the cloth roller are clamped and hot-melt sealed. The bottom of the cloth roller is shielded by the bending of the plastic film as a whole and does not need to be hot-melt sealed. During hot-melt clamping, the cutter 36 will also contact the pad 6 to cut the plastic film above, and at the same time, the plastic film is clamped again with the help of the picking unit 8; the sealed cloth roller is vertical on the supporting platform 4, and by driving the drag-and-drop structure 5 close to the cutting unit 3, the supporting roller 54 on the swing arm 52 is caused to flip upward from the bottom of the folding arm 22 to push the cloth roller, and the supporting roller 54 in the drag-and-drop structure 5 located above the conveyor belt body 12 is slowly controlled to increase the spacing, thereby cooperating with each other to realize that the cloth roller is tilted between the folding arm 22 on the right side after packaging and is carried by the drag-and-drop structure 5;

[0055] S8. Finally, the cloth roller is flipped and packaged by flipping and resetting the folding arm 22, and then moved from the left folding arm 22 to the right folding arm 22. After the folding arm 22 is reset, the supporting roller 54 of the dragging and dropping structure 5 is relatively separated and opened under the cloth roller, so that the cloth roller falls onto the conveyor belt body 12 by its own gravity and is transferred through the conveyor belt body 12.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
