[0030] See also Figure 1-4 The non-woven fabric trimming device comprises a trimming assembly 1, a material pushing kit 2, a steering member 3 and a winding assembly 4. The trimming assembly 1 comprises a unwinding portion 11, on which a material guiding portion 12 and a trimming portion 13 are sequentially arranged along the feeding direction of the roll non-woven fabric. The material pushing kit 2 is symmetrically arranged on the material guiding portion 12, the steering member 3 is arranged on one end of the trimming portion 13 close to the material guiding portion 12, and the winding assembly 4 is arranged on the trimming portion 13.

[0031] Based on the above, this embodiment combines the material guiding part 12 with the material pushing kit 2, so that the two edges of the non-woven fabric unrolled and fed by the unwinding part 11 are stretched outward during the transmission process, so that the non-woven fabric as a whole remains taut, and cooperates with the trimming part 13 to neatly cut the edges of the non-woven fabric, and the cut edge materials are also offset to both sides by the pushing kit 2, and then rolled up by the winding assembly 4 after passing through the steering part 3, so that the cut edge materials of the roll non-woven fabric can be rolled up before entering the slitting machine, which is convenient for the later material collection and recovery.

[0032] See also Figure 1-4 The material guiding portion 12 includes a base 121, a bracket 122 and a material guiding cylinder 123. The base 121 is arranged on the unwinding portion 11, the bracket 122 is symmetrically arranged on the base 121, and a mounting hole is opened on the bracket 122. The material guiding cylinder 123 is arranged between the brackets 122 through the mounting hole.

[0033] The above-mentioned material guiding part 12 assists the non-woven fabric to be transmitted to the slitting machine, and the bracket 122 is inclined in the feeding direction of the non-woven fabric. An opening connected to the mounting hole is provided on the bracket 122. The material guiding cylinder 123 is placed into the mounting hole through the opening, and then a nut is installed on the central axis of the material guiding cylinder 123 to contact with the bracket 122 to fix the material guiding cylinder 123.

[0034] It should be noted that the non-woven fabric is in a tensioned state during the entire transmission process. In this embodiment, at least two groups of material guide cylinders 123 are set, which are arranged from top to bottom along the inclined direction of the bracket 122. The non-woven fabric goes around from the lowest material guide cylinder 123 to between the highest material guide cylinder 123, and finally leaves from above the highest material guide cylinder 123.

[0035] Based on the connection between the material guide cylinder 123 and the bracket 122, the pushing kit 2 of this embodiment includes a sleeve 21, a fastener 22 and a ring 23. The sleeve 21 is arranged on the central axis of the material guide cylinder 123, the fastener 22 is arranged between the sleeve 21 and the central axis of the material guide cylinder 123, and the ring 23 is arranged on the sleeve 21.

[0036] The fastener 22 adopts a clamp-like structure design, and a portion of the fastener 22 is integrally arranged with the sleeve 21. The sleeve 21 is inserted into the central axis of the material guide barrel 123. A portion of the fastener 22 is tightly attached to the central axis of the material guide barrel 123, and then the other portion covers the portion to cover the central axis of the material guide barrel 123. Then, the matching bolts and nuts are connected to fix the sleeve 21 on the material guide barrel 123.

[0037] In the transmission direction of the non-woven fabric, the spirally arranged ring 23 can rotate along the direction of the guide tube 123 according to the sleeve 21, and cooperate with the rotation of the sleeve 21 to form an outer side to extend the contacted non-woven fabric outward to keep the edge of the non-woven fabric flat.

[0038] Taking into account that the sleeve 21 is fixed on the central axis by contact with the material guide cylinder 123 roller through the fastener 22, a socket is provided on the material guide cylinder 123 roller in this embodiment, and a plug rod is provided on the sleeve 21, and the plug rod is arranged in the socket. Through the cooperation of the plug rod and the socket, the other end of the sleeve 21 is restricted on the material guide cylinder 123 roller, which can further improve the stability of the installation of the sleeve 21.

[0039] See also Figure 1-4 The trimming portion 13 includes legs 131 symmetrically arranged on the unwinding portion 11 , a mounting frame 132 is arranged between the legs 131 , a cutter 133 is arranged on the mounting frame 132 , and a steering member 3 is arranged on the mounting frame 132 , and the steering member 3 is located above the sleeve 21 .

[0040] When the non-woven fabric leaves the material guide cylinder 123 at the highest point, the mounting frame 132 is arranged above the material guide cylinder 123 through the support legs 131, and the cutter 133 is connected to the mounting frame 132 by a clamping hoop structure, and is installed on the material guide cylinder 123 in an adjustable manner to cut the edges of the transmitted non-woven fabric, and the cut edges are offset to both sides by the rotating ring 23, and move through the steering member 3 under the traction of the winding assembly 4.

[0041] See also Figure 1-4 The winding assembly 4 includes a turntable 41 disposed on the support leg 131 , a positioning rod 42 is disposed on the turntable 41 , and a transmission member 43 for driving the turntable 41 is disposed on the support leg 131 .

[0042] Based on the winding component 4 for winding and slitting the edge materials, the transmission part 43 of this embodiment adopts a reduction motor and a belt combination. The reduction motor is arranged on the support foot 131 and is connected to the turntable 41. The belt is arranged between the two turntables 41. By placing a reel on the positioning rod 42, the turntable 41 is driven by the reduction motor, and the turntable 41 on the other side is rotated in conjunction with the belt to wind up the slit edge materials.

[0043] It should be noted that the turntables 41 on both sides rotate in the same manner under the belt drive, and the steering member 3 used as the intermediate transmission is designed as a guide wheel in a truncated cone state. The steering member 3 on the same side of the reduction motor is height-crossed with the steering member 3 on the other side. The edge passes under the steering member 3 and is rolled up onto the positioning rod 42, and the edge material of the steering member 3 on the other side passes from above and is rolled up by the roller. In this way, after the edge material is rolled up, the rolled edge material can be removed along the positioning rod 42, which makes it convenient to take the material.

[0044] Considering that the edge material is irregular and may be tangled during winding, a pressure ring 5 that can move along the positioning rod 42 is provided on the turntable 41 of this embodiment. By placing the pressure ring 5 to cover the upper limit of the reel, the winding space is limited to ensure the winding.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
