[0027] In the initial state, the two rotating rods 8 tend to be parallel, the two deviation-correcting rollers 9 are away from each other, and the retracting cylinder 5 is not installed.

[0028] When in use, the retracting cylinder 5 wound with the unheated pearl cotton is installed on the feeding rod, and the retracting cylinder 5 for winding and pressing the pearl cotton is installed on the feeding rod, so that the free end of the pearl cotton passes around the first guide roller 3 and the second guide roller 4 in turn, and then the free end of the pearl cotton passes between the two pressing rollers 7 and is fixed on the retracting cylinder 5 located on the feeding rod, and the two rotating rods 8 are driven to rotate synchronously in the opposite direction by the driving member, and the two correcting rollers 9 are approached to each other until the two correcting rollers 9 are rolled and overlapped with the pearl cotton, driving the feeding rod to rotate, driving the two feeding rods to rotate synchronously in the opposite direction, and driving the two pressing rollers 7 to rotate synchronously in the opposite direction.

When the heat sealing is completed, the two rotating rods 8 are driven by the driving element to rotate synchronously in the opposite direction, and the two correcting rollers 9 are away from each other, and the three retracting cylinders 5 are disassembled in turn;

[0029] In summary, when used, the present application can avoid skewing and misalignment between the two rolls of pearl cotton, thereby ensuring the quality and aesthetics after heat sealing, and is therefore more practical.

[0030] like Figure 3 As shown, in some embodiments, the frame 1 is rotatably provided with support wheel groups 10 which are the same in number as the retractable cylinders 5 and are in one-to-one rolling overlap, and the number of a single support wheel group 10 is two and both are in a vertical direction;

[0031] Referring to the above, when the retractable cylinder 5 rotates, the retractable cylinder 5 is supported by the supporting wheel group 10 for rolling, thereby improving the stability of the retractable cylinder 5 during rotation and avoiding shaking, thereby further avoiding skewing and misalignment between the two rolls of pearl cotton.

[0032] like Figure 3 As shown, in some embodiments, a limit ring plate 11 and a convex strip 12 are provided on the shaft rod 2, the limit ring plate 11 is in a vertical direction and fixed on the shaft rod 2, the convex strip 12 is in a horizontal direction and fixed on the shaft rod 2, a groove 13 corresponding to the convex strip 12 is provided on the retractable cylinder 5, the groove 13 is provided along the length direction of the retractable cylinder 5, the retractable cylinder 5 is in contact with and overlapped with the limit ring plate 11, and a locking nut 14 in contact with and overlapped with the retractable cylinder 5 is threadedly provided on the shaft rod 2;

[0033] With reference to the above, when installing the retractable cylinder 5, the retractable cylinder 5 is placed in a horizontal direction and completely located on the shaft 2, and the convex strip 12 corresponds to and is inserted into the groove 13 until the retractable cylinder 5 and the limiting ring plate 11 are in contact and overlapped, and then the locking nut 14 is tightened onto the shaft 2 until the locking nut 14 and the retractable cylinder 5 are in contact and overlapped, so as to realize the installation of the retractable cylinder 5. When the shaft 2 rotates, the retractable cylinder 5 is driven to rotate together through the cooperation of the convex strip 12 and the groove 13. Conversely, the locking nut 14 is loosened to be away from the shaft 2, so that the retractable cylinder 5 is away from the shaft 2, and the retractable cylinder 5 can be disassembled.

[0034] like Figure 4-Figure 5 As shown, in some embodiments, the heating element includes an air inlet fan 15, a heating cylinder 16 and two heating tubes 17, all of which are arranged on the frame 1. The air inlet fan 15, the heating cylinder 16 and the heating tube 17 are all fixedly arranged on the frame 1. The two heating tubes 17 are both in a horizontal direction and are spaced apart from each other. The output end of the air inlet fan 15 is connected to the heating cylinder 16. A heating wire 18 is arranged in the heating cylinder 16. The heating wire 18 is fixedly arranged in the heating cylinder 16. The heating cylinder 16 is connected to a first three-way pipe 19. The two free ends of the first three-way pipe 19 are respectively connected to the two heating tubes 17. A plurality of hot air holes 20 are opened on the heating tube 17.

The hot air enters the first three-way pipe 19 and the two heating tubes 17 in turn, and is finally blown out to the pearl cotton through multiple hot air holes 20 to achieve heating of the opposite sides of the two rolls of pearl cotton.

[0036] like Figure 6 As shown, in some embodiments, the cooling member includes a blower 21, a cooling cylinder 22 and two cooling pipes 23, all of which are arranged on the frame 1.

The output end of the blower 21 is connected to the cooling cylinder 22. A plurality of semiconductor cooling sheets 24 and a second three-way pipe 25 are arranged on the cooling cylinder 22. The semiconductor cooling sheet 24 has a relatively distributed cold end and a hot end, wherein the cold end is located in the cooling cylinder 22 and the hot end is located outside.

A plurality of cold air holes 26 are opened on the cooling pipe 23, and the plurality of cold air holes 26 are arranged in an array along the length direction of the cooling pipe 23.

[0037] Referring to the above, when in use, the blower 21 and the semiconductor refrigeration plate 24 work, and the natural wind from the outside enters the cooling tube 22 through the blower 21, and then forms cold wind, which enters the second three-way pipe 25 and the two cooling tubes 23 in turn, and is finally blown out to the pearl cotton through multiple cold air holes 26 to achieve cooling of the pressed pearl cotton.

[0038] like Figure 4-Figure 6 As shown, in some embodiments, the apertures of the multiple hot air holes 20 increase along the length direction of the heating tube 17, and the apertures of the multiple cold air holes 26 increase along the length direction of the cooling tube 23. The closer to the connection between the heating tube 17 and the first three-way tube 19, the smaller the aperture of the hot air hole 20, and vice versa. The closer to the connection between the cooling tube 23 and the second three-way tube 25, the smaller the aperture of the cold air hole 26, and vice versa. This design can make the hot air and cold air flow rate and flow rate blown out by the multiple hot air holes 20 and the multiple cold air holes 26 basically consistent, so that the heating and cooling of the pearl cotton are more uniform.

[0041] like Figure 8 As shown, in some embodiments, the driving member includes two sliders 28 that are both slidably arranged on the frame 1, the sliders 28 slide in the horizontal direction, a forward and reverse screw 29 is rotatably arranged on the frame 1, the forward and reverse screw 29 is in the horizontal direction, the two sliders 28 are respectively threadedly matched with the forward and reverse thread segments of the forward and reverse screw 29, a fixed rack 30 is arranged on the slider 28, the fixed rack 30 is in the horizontal direction and fixed on the slider 28, and a fixed gear 31 meshing with the fixed rack 30 is arranged on the rotating rod 8, the fixed gear 31 is in the horizontal direction and fixed on the rotating rod 8;

[0042] Referring to the above, in the initial state, the two sliders 28 are away from each other, the two rotating rods 8 tend to be parallel, and the two correcting rollers 9 are away from each other. When in use, the forward and reverse screws 29 are driven to rotate forward, and the two sliders 28 are synchronously slid in reverse due to the action of the forward and reverse threads until they are close to each other, the fixed rack 30 moves with the slider 28, and the fixed gear 31 rotates due to the meshing action and drives the rotating rod 8 to rotate together, and the two correcting rollers 9 are close to each other.
