[0030] In this embodiment, a winding mechanism 3 is provided at one end of the workbench 1, and the winding mechanism 3 is at least used for winding the non-woven fabric;

[0031] Specifically, the winding mechanism 3 includes a bracket 31 fixedly mounted on the outer wall of one side of the workbench 1, and a winding roller 32 is provided at the top of the bracket 31, and a driving member 33 installed on the bracket 31 is provided at one end of the winding roller 32. The driving member 33 can be composed of a motor and a reducer. The winding roller 32 is driven to rotate by the driving member 33 to realize the winding operation of the non-woven fabric.

[0032] In this embodiment, conveying roller assemblies 4 are provided on both sides of the top of the workbench 1, and the conveying roller assemblies 4 are at least used to convey and guide the non-woven fabric;

[0033] Specifically, the conveying roller assembly 4 includes a support column 41 arranged above the workbench 1, and a roller 1 42 and a roller 2 43 are arranged on the top of the workbench 1 through the support column 41. Figure 2 As shown, the non-woven fabric enters from the top of roller 1 42 to the bottom of roller 2 43, and then passes through the top of the stretching roller 5. The non-woven fabric is inserted into the conveying roller assemblies 4 on both sides of the workbench 1 in the same manner.

[0034] In this embodiment, guide assemblies 6 are provided on both sides of the top of the workbench 1, and stretching rollers 5 are provided above the guide assemblies 6;

[0035] Specifically, the guide assembly 6 includes a limit seat 63 arranged on the outer wall of the top of the workbench 1, and a lifting rod 65 is slidably inserted inside the limit seat 63. A groove 64 is provided on the outer wall on one side of the limit seat 63. The groove 64 is designed so that when the lifting rod 65 falls to a low place, the cross bar 62 can enter the groove 64 without movement interference. A mounting seat 61 is fixedly installed on the top of the lifting rod 65, and a cross bar 62 is provided between the two mounting seats 61. The stretching roller 5 is provided on the two mounting seats 61. When the transmission mechanism 7 drives the stretching roller 5 to rise and fall, the lifting rod 65 slides inside the limit seat 63 to guide the position of the stretching roller 5, thereby ensuring the lifting and lowering accuracy of the stretching roller 5.

[0036] In this embodiment, a transmission mechanism 7 is provided in the middle of the workbench 1, and the stretching roller 5 is used to at least lift and lower the guide assembly 6 and the transmission mechanism 7 to achieve the stretching operation of the non-woven fabric without stopping the machine;

[0037] Specifically, the transmission mechanism 7 includes a hinge seat 71 provided below the crossbar 62, a connecting rod 72 is rotatably connected to the bottom of the hinge seat 71, a pin 73 is provided at the bottom of the connecting rod 72, and a swing rod 74 is provided at the bottom end of the connecting rod 72 through the pin 73, and a driving motor 75 fixed below the workbench 1 is provided at one end of the swing rod 74;

[0038] Specifically, the drive motor 75 is started, and the drive motor 75 drives the swing rod 74 to rotate. The swing rod 74 drives the connecting rod 72 to reciprocate through the pin shaft 73. The connecting rod 72 and the hinge seat 71 can drive the cross bar 62 to reciprocate up and down, and drive the stretching roller 5 above the cross bar 62 to reciprocate and rise and fall. When the stretching roller 5 is raised, the non-woven fabric above the stretching roller 5 can be lifted. As the stretching roller 5 rises, the stretching operation of the non-woven fabric is achieved;

[0039] At the same time, when the winding mechanism 3 does not stop, when the stretching roller 5 is at the highest point, the stretched non-woven fabric is located between the two conveying roller assemblies 4. After the driving motor 75 drives the swing rod 74 to rotate one circle, the winding mechanism 3 just rewinds the stretched non-woven fabric. When the stretching roller 5 is at the top again, the non-woven fabric of the next cycle is rewound, thereby realizing continuous stretching and rewinding of the non-woven fabric.

[0040] Specifically, the swing arm 74 includes a fixed rod 741 connected to the pin shaft 73 and the connecting rod 72, and a sliding frame 742 is fixedly provided at one end of the fixed rod 741, a sliding groove 743 is provided on one side of the sliding frame 742, and a positioning groove 744 connected to the sliding groove 743 is provided on the top and bottom of the sliding frame 742. A slider 745 is slidably inserted in the interior of the sliding groove 743, and the slider 745 is fixedly installed on the output shaft of the driving motor 75. A threaded column 746 located in the positioning groove 744 is provided on the top and bottom of the slider 745. A locking nut 747 is threadedly sleeved on the threaded column 746 and contacts the surface of the sliding frame 742.

[0041] The swing rod 74 structure here can adjust the length of the swing rod 74, thereby changing the rotation trajectory of the swing rod 74 and changing the rotation radius of the swing rod 74;

[0042] Specifically, the operator can loosen the locking nut 747 so that the slider 745 can slide freely inside the slide groove 743. After the slider 745 slides to the specified position, the operator can fix the locking nuts 747 in the upper and lower positions on the threaded column 746 again. The rotation radius of the swing rod 74 can be changed to achieve the effect of changing the reciprocating height of the stretching roller 5, and also to adjust the stretching force and degree of the non-woven fabric.
