[0059] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0060] Refer to the attached Figure 1-6 A glass fiber felt winding device includes a mounting frame 1, on which a first positioning roller assembly 2, a first tensioning roller 3, an intermediate roller 4, a second tensioning roller assembly 7, a heating roller 5, and a second positioning roller assembly 9 are sequentially arranged along a feeding direction. The positioning roller of the second positioning roller assembly 9 is driven by a servo motor (not shown in the figure) to achieve winding.

[0061] The heating roller pair 5 is a pair of heating rollers arranged parallel to each other from top to bottom, and the upper edge of the middle roller 4 is flush with the upper edge of the lower heating roller;

[0062] The second tensioning roller assembly 7 is provided with a pair and is arranged on both sides of the width direction of the felt. The second tensioning roller assembly 7 includes a U-shaped bracket 73, a driven roller 72 rotatably supported on the side wall of the U-shaped bracket 73 and arranged from top to bottom, an active roller, and a servo motor 75 installed on the U-shaped bracket 73 and driving the active roller to rotate. The axis of the active roller is inclined to the feeding direction of the felt. The driven roller 72 and the transmission roller 71 extend into the mounting frame 1 and the driven roller 72 and the transmission roller 71 are located on the side of the extension to form an opening for the felt to extend out (that is, there is no inner side wall of the U-shaped bracket 73 blocking it). The bottom of the U-shaped bracket 73 is rotatably supported on the support seat through the rotating shaft 76, and the support seat is fixed to the outside of the mounting frame 1.

[0063] During the winding process, the felt passes through the first tensioning roller 3, the intermediate roller 4, the second tensioning roller assembly 7 and the heating roller 5 in sequence; among them, the first positioning roller assembly 2 roughly positions the felt through a pair of first locking rings 22; the first tensioning roller 3 is used to maintain the tension of the fabric; the active roller and the driven roller 72 of the second tensioning roller assembly 7 are arranged obliquely to the feeding direction of the felt, and the conveying of the felt by the active roller can be decomposed into two directions, forward and outward, that is, the pair of second tensioning roller assemblies 7 have the function of pulling the two sides of the felt outward while maintaining the forward feeding process, so that the felt remains in a taut state before passing through the subsequent heating roller 5, thereby improving the wrinkle elimination effect of the subsequent heating roller 5; the heating roller 5 heats and squeezes the felt to realize ironing and smoothing operation to eliminate wrinkles; in other embodiments, a pair of second tensioning roller assemblies 7 can also be additionally arranged between the heating roller 5 and the second positioning roller assembly 9 to further eliminate wrinkles on the felt.

[0064] In this embodiment, the bearing blocks 65 at both ends of the first tensioning roller 3 and the bearing blocks 65 at both ends of the upper heating roller of the heating counter roller 5 are connected to a roller height adjustment assembly 6. The roller height adjustment assembly 6 comprises a screw 61, a nut block 62, a spring 63, and a handwheel 64. A vertically extending guide slot 111 is provided on the mounting plate 11 of the mounting frame 1. The bearing blocks 65 are slidably mounted in the guide slot 111. The upper end of the screw 61 passes through the nut block 62 and is connected to the handwheel 64. The lower end of the screw 61 is rotatably connected to the upper end of the bearing block 65. The spring 63 is sleeved around the screw 61, with its ends respectively abutting the nut block 62 and the bearing block 65. By turning the handwheel 64 of the roller height adjustment assembly 6, the tension of the felt and the extrusion force applied to the felt can be adjusted.

[0065] In this embodiment, the first positioning roller assembly 2 and the second positioning roller assembly 9 each include a positioning roller, a first locking collar 22, and a first locking bolt 23. The first locking collar 22 is sleeved on both axial sides of the positioning roller 21. The first locking bolt 23 is radially threadedly connected to the first locking collar 22 and tightens against the positioning roller 21. The first positioning roller assembly 2 is primarily used for coarse positioning of the felt, while the second positioning roller assembly 9 is primarily used for precise positioning of the reel for winding the felt.

[0066] In this embodiment, the winding device is equipped with a synchronous shaft assembly 8 located below the support base. This synchronous shaft assembly 8 is used to drive the U-shaped bracket 73 of the second tensioning roller assembly to rotate synchronously. Specifically, the synchronous shaft assembly 8 includes a synchronous shaft 81, a second locking collar 83, and a second locking bolt 84. The synchronous shaft 81 passes through the mounting plates 11 on both sides of the mounting frame 1 and is coupled to the rotating shaft 76 via a bevel gear 82. A handwheel is mounted on one end of the synchronous shaft 81. The second locking collar 83 is fixed to the mounting plate 11 and sleeved onto the synchronous shaft 81. The second locking bolt 84 is radially threadedly connected to the second locking collar 83 and tightens the synchronous shaft 81. After loosening the second locking bolt 84, the handwheel can be turned to synchronously adjust the tilt angle of the second tensioning roller assembly 7. A clamping unit can also be installed to press-fit the U-shaped bracket 73, improving the stability of the second tensioning roller assembly 7.

[0067] In this embodiment, the active roller is rotatably supported at both ends by the side walls of a U-shaped bracket 73 (the upper edge of the active roller is higher than the inner side wall of the U-shaped bracket 73). One end of the driven roller 72 is rotatably supported by the outer side wall of the U-shaped bracket 73. A support platform extends outward from the bottom of the outer side wall of the U-shaped bracket 73. The servo motor 75 is fixed to the support platform and is in transmission engagement with the active roller via a gear set 74. Specifically, the driven roller 72 includes a core shaft 721 and a sleeve 722. The sleeve 722 is sleeved around the core shaft 721 and rotatably engaged with the core shaft 721 at both ends via bearings 723. One end of the core shaft 721 is fixedly connected to the outer side wall of the U-shaped bracket 73.
