Description

Technical Field

[0001] This utility model belongs to the field of carbon fiber production technology, specifically relating to a filament roll unwinding and guiding device. Background Technology

[0002] In the actual production process of carbon fiber, there is a process called the unwinding process. The main purpose of this process is to remove the raw filament from the spool and allow it to enter the next oxidation process. The raw filament is wound in a figure-eight shape on a hollow tube. During unwinding, the spool rotates, and the raw filament crawls forward under the action of traction force. The diameter of the spool gradually decreases, and at the same time, the raw filament swings left and right along the axis of the spool. The raw filament passes around the retaining roller and changes its running direction.

[0003] As the raw yarn passes over the retaining roller, although the roller rotates under friction, the raw yarn, wound in a figure-eight shape around the hollow tube, wobbles left and right during unwinding. This inevitably causes sliding friction between the raw yarn and the retaining roller surface. The wrap angle between the raw yarn and the retaining roller gradually increases, and the sliding friction also increases, increasing the probability of yarn breakage. Because the retaining roller has a small radius of curvature, broken yarns trapped in the raw yarn bundle will also become entangled on its surface. Over time, the surface of the retaining roller will be covered with broken yarns, further increasing the sliding friction between the raw yarn and the retaining roller. More broken yarns will become entangled on the surface of the retaining roller, further increasing the probability of yarn breakage. These broken yarns wrapped on the retaining roller can only be cleaned manually, which is time-consuming and labor-intensive.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a filament roll unwinding and guiding device.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figures 1 to 6 As shown, a filament unwinding and guiding device according to an embodiment of the present invention includes: a bracket 1 and a filament guiding device 2.

[0031] like Figures 1 to 2 As shown, a pair of brackets 101 are fixed on the support 1, and a sliding rod 102 is fixed between the pair of brackets 101. The sliding rod 102 is used for the slider 103 to slide on it. The slider 103 is slidably mounted on the sliding rod 102. Because the silk thread is wound into a figure-eight shape, it swings along the axis of the silk roll when unwinding. The swing of the silk thread drives the rotating rod 205. Since the rotating rod 205, the support rod 204, and the fixing plate 202 are fixed to the slider 103 through the bending plate 201, the swing of the silk thread causes the slider 103 to slide left and right on the sliding rod 102. A flat plate 109 is installed on the support 1. The flat plate 109 is used to hold the slider 103 in place and prevent the slider 103 from rotating on the sliding rod 102.

[0032] like Figures 1 to 2 As shown, the bottom of the slider 103 is fixed with multiple pairs of fixed shafts 104, and each pair of fixed shafts 104 is rotatably equipped with rollers 105. The rollers 105 slide against the surface of the flat plate 109. By sliding the rollers 105 on the flat plate 109, the friction between the slider 103 and the flat plate 109 is effectively reduced, and the slider 103 is prevented from rotating on the slide rod 102.

[0033] like Figures 1 to 2 As shown, the inner wall of the slider 103, which is in contact with the slide rod 102, has multiple ball grooves 106. Balls 107 are slidably disposed within the ball grooves 106. By providing balls 107 on the inner wall of the slider 103 in contact with the slide rod 102, the sliding friction between the slider 103 and the slide rod 102 is effectively reduced. The top of the slider 103 has multiple mounting grooves 108 for mounting the wire guide device 2.

[0034] like Figure 1 and Figure 3As shown, the guide wire device 2 is installed on the sliding block 103, and the guide wire device 2 comprises a bending plate 201, and a pair of fixed plates 202 are installed on the bending plate 201. A guide wire wheel frame 203 is fixed on the pair of fixed plates 202, which is used to support the upper fixed plate 202 and install a rotating shaft 206. The rotating shaft 206 is rotatably arranged on the guide wire wheel frame 203, and is used to install a guide wire wheel 207 and drive the guide wire wheel 207 to be slidably arranged with the guide wire wheel frame 203. The rotating shaft 206 is installed with the guide wire wheel 207, and the guide wire wheel 207 is used for the wire to pass through it to change the running direction of the wire and reduce the friction of the wire, thereby reducing the risk of wire breakage. The top end of the fixed plate 202 is provided with a fixed seat 208 for installing a thread separating wheel 210, and a pair of supporting rods 204 are fixed between the pair of fixed plates 202, which are used to support the upper fixed plate 202 and install a rotating rod 205.

[0035] As shown in the figure, Figures 3 to 6 A pair of rotating rods 205 are slidably arranged on the pair of supporting rods 204, and the wire passing between the pair of rotating rods 205 drives the rotating rods 205 to rotate, thereby reducing the friction and reducing the risk of wire breakage. A pair of thread separating rods 209 are fixed on the fixed seat 208, and a thread separating wheel 210 is slidably arranged on the pair of thread separating rods 209. When the wire passes between the pair of thread separating wheels 210, the thread separating wheels 210 are driven to rotate on the thread separating rods 209, thereby reducing the friction and reducing the risk of wire breakage.

[0036] As shown in the figure, Figures 3 to 6 A limiting ring 211 is fixed on the rotating shaft 206, which limits the guide wire wheel 207, and the center of the guide wire wheel 207 is just aligned between the pair of rotating rods 205 and the pair of thread separating wheels 210. A plurality of insertion rods 214 are fixed on the limiting ring 211, which are used to be inserted into the insertion hole 213, so that the guide wire wheel 207 drives the rotating shaft 206 to rotate when rotating.

[0037] As shown in the figure, Figures 3 to 6 A fixed ring 212 is fixed on the guide wire wheel 207, and a plurality of insertion holes 213 corresponding to the insertion rods 214 are dug in the fixed ring 212. The insertion rods 214 are inserted into the insertion holes 213, so that the guide wire wheel 207 drives the rotating shaft 206 to rotate when rotating. A fastening head 215 is threadedly connected to the end of the rotating shaft 206 away from the guide wire wheel frame 203, and the guide wire wheel 207 is fixed on the rotating shaft 206 by screwing the fastening head 215 on the rotating shaft 206. A fixed support 216 is fixed between the pair of fixed plates 202 and the guide wire wheel frame 203, which plays a role in fixing and supporting.

[0038] Working principle: firstly, the thread end on the thread roll is passed between a pair of rotating rods 205, then passed around the bottom of the thread guide wheel 207, and then passed between a pair of thread separating wheels 210, and the thread is connected to a front-end traction device, and then the power is started to rotate the thread roll, and the front-end traction device pulls the thread at the same time, the thread changes its running direction after passing through the rotating rod 205 and around the thread guide wheel 207, and during the running process, because the thread is wound into a thread roll in an 8-shaped manner, the thread swings along the axial direction of the thread roll when it is unwound, and the swinging of the thread drives the rotating rod 205, and because the rotating rod 205, the supporting rod 204 and the fixed plate 202 are fixed on the sliding block 103 through the bent plate 201, the sliding block 103 slides left and right on the slide rod 102 when the thread swings, and the fixed shaft 104 at the bottom of the sliding block 103 contacts and slides on the flat plate 109, preventing the sliding block 103 from rotating on the slide rod 102.
