[0040] The technical solutions in the utility model will be described clearly and completely below in combination with the specific implementation manners of the utility model. Obviously, the described implementation manners are only part of the implementation manners of the utility model, rather than all the implementation manners. Based on the implementation manners in the utility model, all the other implementation manners obtained by the ordinary skilled in the art without making creative efforts belong to the protection scope of the utility model.

[0041] As shown in Figures 1-4 the utility model discloses a cooling fin split device, the overall shape is similar to the traditional pliers, including a pair of handles 1, still including split filament 2.

[0042] Among them, the upper end of handle 1 is hingedly connected with each other, and handle 1 is opened and closed around the hinge point; the top of handle 1 is provided with mounting groove 101, and the mounting groove 101 on one handle 1 extends to the right horizontally to form long groove structure, and the mounting groove 101 on the other handle 1 extends to the left horizontally to form another long groove structure; split filament 2 is detachably provided with several on each mounting groove 101, and several split filament 2 are parallel to each other.

[0043] In the structure, the lower end part of handle 1 is used for operator to hold and force, and the upper end part is hingedly connected through a rotating shaft, so that handle 1 can rotate around the rotating shaft, thereby controlling split filament 2 to carry out gathering and dispersing action. When splitting, split filament 2 replaces the traditional finger silk operation, and the precise split of electronic grade glass fiber monofilament is realized.

[0044] During the splitting process, the hand handle 1 is used to horizontally insert the splitting piece 2 into the corresponding splitting gap, and the initial splitting is performed, so that several single filaments near the splitting gap will not be mistakenly split into other single yarns. Then the operator pinches the handle 1 with one hand to make the splitting piece 2 gather inward, and the required electronic grade glass fiber single filaments passing between the splitting piece 2 are bunched and allocated. Subsequently, the operator uses the other hand to put each bunched and allocated electronic grade glass fiber yarn into the corresponding production area. Since the thickness of the splitting piece 2 is thinner than the finger, the splitting is not easy to make mistakes, and the gathering action of the splitting piece 2 is matched to realize accurate splitting, which can ensure the number of single filaments allocated to each yarn to be accurate and reliable, and improve the product quality.

[0045] In the above cooling fin splitting device, the lower end of the handle 1 is provided with a hand holding part 102, and a return spring 11 is arranged between the two hand holding parts 102, which is a compression spring. Among them, the handle 1 can be automatically reset after operation by the return spring 11, which reduces the labor intensity of the operator and ensures the consistency of each splitting action, further improving the splitting precision and efficiency.

[0046] In the initial state, the return spring 11 is in the stretched state, which is used to keep the distance between the two hand holding parts 102 unchanged. When the operator pinches the handle 1, the return spring 11 is compressed to store power, and after the hand is released, the return spring 11 rebounds to drive the handle 1 to reset.

[0047] Among them, the opposite ends of the two hand holding parts 102 are provided with guide holes 1021, as shown in Figure 3 The inner diameter of the guide hole 1021 is larger than the outer diameter of the return spring 11, and the two ends of the return spring 11 are respectively fixedly connected with the hole bottom of one guide hole 1021. In this structure, the guide hole 1021 is used to guide the extension direction of the return spring 11, so as to avoid the offset or jamming phenomenon of the return spring 11, and ensure the smoothness and consistency of the opening and closing of the handle 1, thereby improving the stability and accuracy of the splitting operation.

[0048] Further, the surface of the hand holding part 102 is provided with anti-skid lines, so as to increase the friction of the hand holding part 102, prevent the handle 1 from slipping off during operation, improve the safety and stability of operation, and especially suitable for the comfort and reliability of long time use.

[0049] In the above cooling fin splitting device, the splitting piece 2 is a rectangular sheet with a thickness of 1-5mm. At the same time, the front end is wedge-shaped, which is convenient for the splitting piece 2 to be quickly inserted into the splitting gap, improves the splitting efficiency, and helps to reduce the damage to the single filament, ensures the high quality standard of the product, and maintains the excellent performance of the product.

[0050] The bottom of the rear end of the filament splitter 2 is provided with a rod-shaped insertion part 201, which is embedded in the installation groove 101 and fixed by a hand screw 3. The bottom end of the insertion part 201 abuts against the groove bottom of the installation groove 101, and the side end of the insertion part 201 abuts against the groove wall of the installation groove 101. Through this structure, the filament splitter 2 can be quickly and firmly fixed, and different specifications of the filament splitter 2 can be adjusted and replaced to adapt to different production process requirements, thereby enhancing the flexibility and applicability of the equipment.

[0051] The groove wall of the installation groove 101 is provided with a through hole 1011 for installing the hand screw 3. The hand screw 3 includes a screw rod end and a hand screw end. The screw rod end of the hand screw 3 penetrates through the through hole 1011 and is screwed with the side of the insertion part 201, and the hand screw end of the hand screw 3 abuts against the outer side wall of the installation groove 101. Through this structure, the stability of the filament splitter 2 after installation is ensured.

[0052] Meanwhile, the side of the insertion part 201 is provided with a threaded hole 2011, and the screw rod end of the hand screw 3 is screwed with the threaded hole 2011. After the insertion part 201 is embedded in the installation groove 101, the screw rod end of the hand screw 3 is inserted into the through hole 1011 and screwed with the threaded hole 2011. After the hand screw 3 is tightened, the hand screw end abuts against the front and back of the outer side wall of the installation groove 101, thereby realizing the fixation of the insertion part 201 and completing the installation and fixation of the filament splitter 2.

[0053] Further, the through hole 1011 extends in the left-right direction to form an oblong shape, and the screw rod end of the hand screw 3 can slide left and right in the through hole 1011. Meanwhile, the insertion part 201 can slide left and right in the installation groove 101. Through this structure, the filament splitter 2 is designed to be detachable, allowing any number of filament splitters 2 to be arranged on the installation groove 101, and allowing the spacing between adjacent filament splitters 2 to be adjustable. Therefore, different thicknesses of filament splitters 2 or different numbers of filament splitters 2 can be adjusted and replaced according to different production process requirements, thereby enhancing the use flexibility and applicability of the device, making it able to cope with various production scenarios, and improving the overall use efficiency of the device.

[0054] As shown in Figure 1 Each insertion part 201 corresponds to one hand screw 3, and the hand screws 3 on the same installation groove 101 share one through hole 1011.

[0055] Further, the top of the installation groove 101 is provided with a length scale line in the left-right direction, which provides an intuitive measurement reference to help the operator accurately adjust the position of the filament splitter 2, improve the installation accuracy of the filament splitter 2, ensure the consistency and accuracy of the filament gap, and improve the product quality.

[0056] During fiber drawing, the glass fiber emerges from the stencil and passes vertically through the cooling plate. When this fiber splitting device is used in conjunction with the cooling plate, the fiber splitting plate 2 needs to be kept vertical to facilitate its smooth insertion into the fiber splitting gap. Therefore, the connection method between the fiber splitting plate 2 and the insertion part 201 includes two embodiments, as detailed below:

[0057] Example 1: As Figure 1 As shown, the rear end of the wire splitting piece 2 is fixedly connected to the front end of the insertion part 201. After being fixed, the wire splitting piece 2 remains in a vertical position.

[0058] Example 2: Figure 4 As shown, the top of the rear end of the wire splitter 2 is hinged to the top of the front end of the insertion part 201 via a pivot. The pivot is horizontally positioned front to back. This structure allows the wire splitter 2 to remain vertical under gravity. This design eliminates the need for the operator to consciously adjust their handheld posture, greatly improving ease of use.

[0059] The method of using the cooling fin beam splitting device of this utility model is as follows:

[0060] Before bundling, a splitting disc 2 is installed on the mounting slot 101. During bundling, the operator holds the handle 1 and inserts the splitting disc 2 horizontally into the corresponding splitting gap. Then, the operator squeezes the handle 1 with one hand to gather the splitting disc 2 inward, thus bundling the required electronic-grade glass fiber monofilaments flowing between the splitting discs 2. Subsequently, the operator uses the other hand to place each bundle of electronic-grade glass fiber yarn into the corresponding production area.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
