Description

Technical Field

[0001] The utility model relates to the technical field of wire collecting machine equipment, in particular to a wire guiding device for a carbon fiber wire collecting machine. Background Art

[0002] According to the patent number: CN217094778U, the patent name is: A static removal device for a pre-oxidation furnace for carbon fiber production. The pressure block in the device is in contact with the winding roller and is fixed to the side plate by bolts. Pressure can be applied to the winding roller to ensure good contact between the winding roller and the carbon fiber tow, thereby ensuring that the carbon fiber tow can be effectively controlled when passing through the winding roller. However, during long-term use, the carbon fiber tow will maintain a certain speed through the pressure block and the card slot, which will cause wear on its surface. Large wear will cause the stroke of the carbon fiber tow to change, causing the winding roller to shift during operation, affecting the winding quality of the carbon fiber. For this reason, we propose a wire guide device for a carbon fiber winding machine. Utility Model Content

[0024] 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.

[0025] Refer to the attached Figure 1-4 The utility model provides a wire guide device for a carbon fiber wire collecting machine, comprising a wire guide side plate 1 and a wire guide pressure rod 2 detachably pressed on the wire guide side plate 1. Bolts 23 are provided at the edge positions of both sides of the wire guide pressure rod 2. The bolts 23 are threaded through the wire guide pressure rod 2 and are threadedly matched with the wire guide side plate 1 to achieve disassembly. A guide groove 11 is vertically provided on the wire guide side plate 1, so that a pressure block 21 on the wire guide pressure rod 2 is pressed and slid into the guide groove 11. After pressing, a space is formed to accommodate the placement of the wire guide device 3.

[0026] The wire guide device 3 is slid along the guide groove 11 and placed in the guide groove 11 until it slides into the bottom of the guide groove 11 and forms a hole for the carbon fiber filaments to pass through;

[0027] The wire guide device 3 includes a wire guide plate 31, an extension plate 32, and a clamping plate 33 connected in sequence, and the wire guide plate 31, the extension plate 32, and the clamping plate 33 are relatively arranged to form a hole, that is, a single wire guide plate 31, the extension plate 32, and the clamping plate 33 are a semicircular structure. In order to achieve the semicircular structure, one side of the wire guide plate 31 is a semicircular opening, and the rest of the position is a corner structure. The corner structure can act as a sliding block for limiting the guide to ensure that the wire guide plate 31 slides smoothly along the guide groove 11. The extension plate 32 is extended at the semicircle of the wire guide plate 31, and the clamping plate 33 is connected to the extension plate When the guide plate 31 is in the bottom part of the guide groove 11, the guide plate 31 is in the bottom part of the guide groove 11, and the guide plate 31 is in the bottom part of the guide groove 11. When the guide plate 31 falls into the bottom part of the guide groove 11, the corner structure of the guide plate 31 slides into the cavity along the limiting groove. A card slot is formed between the upper guide plate 31 and the card plate 33 to engage with the end of the pressure block 21, and a card slot is formed between the lower guide plate 31 and the card plate 33 to engage with the edge of the guide groove 11.

[0028] Chamfers are provided on the outer walls on both sides of the clamping plate 33. On the one hand, the chamfers can reduce the friction between the carbon fiber filaments and the yarn guide, thereby reducing the wear of the carbon fiber filament bundles. On the other hand, the chamfers make docking easier during the threading process, which helps to reduce the difficulty and time of threading.

[0029] In order to better support the guide wire device 3 , an arc-shaped structure is adopted at the end of the pressing block 21 , and the arc is supported and matched with the extension plate 32 .

[0030] In order to further support the wire guide device 3 , a groove 22 is transversely formed on the pressing block 21 . The groove 22 engages the wire guide plate 31 to reduce the shaking of the wire guide device 3 between the guide groove 11 and the pressing block 21 .

[0031] A positioning rod 24 is also connected to the bottom of the guide wire pressure rod 2 , and the positioning rod 24 extends into the guide wire side plate 1 to form a guide positioning to ensure that the guide wire device 3 is correctly positioned in the guide groove 11 .
