Abstract
Description
Technical Field
[0001] The utility model generally relates to the technical field of chemical fiber manufacturing, and more particularly to a yarn dividing reed. Background Art
[0002] In continuous glass fiber thermoplastic composites, sheet thickness and glass fiber content are determined by the glass fiber count and resin volume per unit width. The glass fiber count per unit width is controlled by the yarn reed, while the resin volume is primarily controlled by the extruder output. Therefore, the number of reeds (the number of holes per unit length) significantly impacts product specifications and quality control.
[0003] Traditional yarn splitting reeds are monolithic structures with a fixed number of reeds. They cannot be configured to accommodate different product specifications. To meet the needs of diverse customers, reeds of varying specifications must be replaced when production specifications change. Furthermore, damaged reeds require complete replacement, impacting production efficiency and increasing manufacturing costs. Utility Model Content

[0044] First embodiment
[0045] Figures 1 to 4 A yarn splitting reed according to a first embodiment is shown. The yarn splitting reed includes a fixed member 100 and a yarn splitting assembly 110. The yarn splitting assembly 110 includes a connecting member 111, at least two yarn splitting teeth 112, a blocking member 115, and an elastic member 116. The connecting member 111 is detachably connected to the fixed member 100. The yarn splitting teeth 112 extend along a first direction D1 and are connected to the connecting member 111. A yarn splitting gap 120 for threading yarn is defined between adjacent yarn splitting teeth 112. The blocking member 115 is rotatably connected to the end of the yarn splitting teeth 112 distal from the connecting member 111 between an open position and a closed position. In the open position, the blocking member 115 allows yarn to enter the yarn splitting gap 120. In the blocking position, the blocking member 115 is at least partially tilted relative to the first direction D1 to prevent yarn from exiting the yarn splitting gap 120. The elastic member 116 is configured to apply a force to the blocking member 115 toward the closed position.
[0046] According to the yarn splitting reed of the present invention, the yarn splitting gap 120 formed by the yarn splitting teeth 112 of the yarn splitting assembly 110 is used to separate the yarns. The yarns enter the yarn splitting gap 120 through the blocking member 115, and the blocking member 115 can prevent the yarns from escaping the yarn splitting gap 120 under the action of the elastic member 116. The yarn splitting assembly 110 can be separately removed from the fixed member 100 via the connecting member 111. When the production specifications change, the yarn splitting assembly 110 of different specifications can be replaced to meet different production needs without having to replace the entire yarn splitting reed, thereby improving production efficiency and reducing production costs.
[0047] Depend on Figure 1 As can be seen, the yarn splitting reed according to the first embodiment includes multiple yarn splitting assemblies 110, which are arranged along a second direction D2 perpendicular to the first direction D1. The arrangement of multiple yarn splitting assemblies 110 allows for individual replacement of damaged yarn splitting assemblies 110 when some of them are damaged, without requiring replacement of the entire yarn splitting reed. This minimizes the impact on production efficiency and reduces production costs.
[0048] Reference Figure 2 and Figure 4 The fixing member 100 is provided with a card slot 101, and the connecting member 111 is constructed as a buckle. The connecting member 111 is fixed to the fixing member 100 through the card slot 101, thereby realizing the detachable installation between the yarn separation assembly 110 and the fixing member 100, with low operation difficulty and high replacement efficiency.
[0049] Further, refer to Figure 4 The slot 101 extends along a second direction D2 perpendicular to the first direction D1, so that a plurality of yarn separation assemblies 110 arranged along the second direction D2 can be installed.
[0050] Optionally, a limiting groove 102 is provided on the inner wall of the card slot 101 parallel to the second direction D2 and one of the connecting members 111, and a limiting block 114 is provided on the inner wall of the card slot 101 parallel to the second direction D2 and the other of the connecting members 111. The limiting block 114 is cooperatively connected with the limiting groove 102, so that the connecting member 111 has a limit relative to the fixed member 100 along the second direction D2, so that the connection between the yarn separation assembly 110 and the fixed member 100 is more stable.
[0051] like Figure 2 and Figure 4 As shown, the card slot 101 is provided with a limiting slot 102, and the side wall of the connecting member 111 is provided with a limiting block 114, so that the connecting member 111 and the fixing member 100 cooperate with each other, so that the yarn separation assembly 110 is not easy to shake along the second direction D2. Figure 4As can be seen, the cross-section of the limiting groove 102 perpendicular to the first direction D1 is trapezoidal, and correspondingly, the cross-section of the limiting block 114 perpendicular to the first direction D1 is also trapezoidal, providing a stable connection. The cross-sections of the limiting groove 102 and the limiting block 114 perpendicular to the first direction D1 can also have other shapes to ensure a stable connection between the connecting member 111 and the fixing member 100.
[0052] Reference Figure 4 The fixing member 100 is provided with at least two protective plates 103, which are arranged on both sides of the slot 101 along a third direction D3 perpendicular to the second direction D2. Furthermore, the protective plates 103 are arranged at both ends of the slot 101 along the second direction D2. The provision of the protective plates 103 provides protection at both ends of the fixing member 100 and both sides of the yarn separation assembly 110, preventing the yarn separation assembly 110 from being damaged by collisions.
[0053] Reference Figure 1 and Figure 2 When the yarn splitting reed is in use, the yarn is tensioned and enters the yarn splitting gap 120 from the blocking member 115 along the first direction D1, so that the yarn is better bundled and not easily dispersed.
[0054] Combine Figure 3 As shown, the blocking member 115 is rod-shaped, and the end of the blocking member 115 is connected to the end of the yarn dividing tooth 112 away from the connecting member 111 through a bearing 117, so that the blocking member 115 is rotatable relative to the yarn dividing tooth 112.
[0055] Optionally, the elastic member 116 is configured as a torsion spring, and is provided with a first connecting end 118 and a second connecting end 119. The first connecting end 118 is connected to the yarn-separating tooth 112, and the second connecting end 119 is connected to the blocking member 115, thereby elastically connecting the blocking member 115 and the yarn-separating tooth 112. During the actual yarn-separating process, the yarn in the tensioned state presses the blocking member 115 along the first direction D1, causing the blocking member 115 to rotate relative to the yarn-separating tooth 112, thereby avoiding the yarn and allowing the yarn to enter the yarn-separating gap 120. After the yarn enters the yarn-separating gap 120, the blocking member 115 returns to its natural state under the action of the elastic member 116, thereby preventing the yarn from escaping the yarn-separating gap 120.
[0056] Optionally, the first connecting end 118 and the second connecting end 119 of the elastic member 116 in the natural state are at an angle of 85° to 95°. Preferably, the first connecting end 118 and the second connecting end 119 of the elastic member 116 in the natural state are at an angle of 90°, so that the blocking member 115 can better close the yarn separation gap 120 and prevent the yarn entering the yarn separation gap 120 from escaping from the yarn separation assembly 110.
[0057] Second embodiment
[0058] The difference between the split yarn reed according to the second embodiment and the split yarn reed according to the first embodiment mainly lies in the difference in the elastic member 216 .
[0059] Depend on Figure 5 It can be seen that the elastic member 216 of the yarn splitting reed according to the second embodiment is constructed as a spring, the first end of the elastic member 216 is connected to the yarn splitting tooth 112, and the second end of the elastic member 216 is connected to the blocking member 115, thereby making the blocking member 115 and the yarn splitting tooth 112 elastically connected.
[0060] During the actual yarn separation process, the yarn in the tensioned state squeezes the blocking member 115 along the first direction D1, causing the blocking member 115 to rotate relative to the yarn separation teeth 112, thereby avoiding the yarn and allowing the yarn to enter the yarn separation gap 120. After the yarn enters the yarn separation gap 120, the blocking member 115 returns to its natural state under the action of the elastic member 216, thereby preventing the yarn from leaving the yarn separation gap 120.
[0061] The torsion spring type elastic member 116 of the yarn splitting reed according to the first embodiment is not easy to contact with the yarn, thereby not easily affecting the yarn splitting operation. The spring type elastic member 216 of the yarn splitting reed according to the second embodiment is easy to replace and maintain, and is easy to operate.
