Description

Technical Field

[0001] This utility model relates to an assembly accessory for weft insertion scissors, specifically a fixing piece for weft insertion scissors, belonging to the field of weft insertion scissor assembly technology. Background Technology

[0002] Weft splicing rapier assembly involves assembling its components (such as the weft clamping rod and the rapier housing) to achieve the weft splicing function. The fixing plate is often located at the tail of the weft splicing rapier and is used in scenarios where the weft yarn needs to be firmly clamped, so as to better assemble and use the weft splicing rapier.

[0003] The existing utility model with authorization announcement number CN216237513U discloses a special rapier head for weft insertion of strip sheet materials on a rapier loom. In use, the mounting base at one end of the rapier head body is installed into the connecting groove inside the rapier shaft at one end via a connecting block, and then connected and fixed by bolts through the through holes. The tight layer on the inner wall of the connecting groove is made of rubber, which allows the connecting block to be set more tightly and firmly in the connecting groove, effectively reducing wear on the connecting block and preventing it from shaking, thus improving the stability and firmness of the rapier head during use. Moreover, with this connection method, when the rapier head body is damaged or excessively worn during long-term use, only the rapier head body needs to be disassembled, without replacing the entire rapier head, reducing cost expenditure and waste.

[0004] While the above technical solution facilitates the assembly and disassembly of the weft insertion scissor head, the connecting block structure used for assembly is essentially a fixing plate structure at the tail of the weft insertion scissor head. This structure only allows for fixed-position assembly and lacks a fine-tuning structure for adjusting the angle and extension / retraction position of the weft insertion scissor head. Consequently, the weft insertion scissor head structure is inconvenient to fine-tune during actual use, limiting its application scenarios and flexibility. Therefore, a fixing plate for the weft insertion scissor head is proposed here. Utility Model Content

[0005] This utility model proposes a fixing piece for weft insertion scissors to solve the problem that the existing weft insertion scissors structure is inconvenient to fine-tune in actual use, which limits its application scenarios and makes its use less flexible.

[0006] This utility model is achieved through the following technical solution: a fixing piece for weft-joining sword head, including a sword head body, wherein a fixing piece fine-tuning mechanism is provided on the outer side of the sword head body;

[0007] The fixed plate fine-tuning mechanism includes an assembly frame, an adjusting frame slidably connected inside the assembly frame, a fine-tuning screw threadedly connected to the inner wall of the assembly frame, an auxiliary bearing fixedly connected to the inner wall of the adjusting frame, the inner ring of the auxiliary bearing fixedly connected to the outer surface of the fine-tuning screw, a support column fixedly connected to the inner bottom wall of the adjusting frame, the outer surface of the support column rotatably connected to the inner wall of the sword head body, a fastening bolt provided inside the sword head body, the outer surface of the fastening bolt contacting the inner wall of the sword head body and the inner wall of the adjusting frame respectively, a fastening nut fixedly connected to the outer surface of the fastening bolt, and the top end of the fastening nut contacting the bottom surface of the adjusting frame.

[0008] Specifically, mounting plates are fixedly connected to both sides of the assembly frame, and each mounting plate has several identical mounting holes on its upper surface.

[0009] Furthermore, limit sliders are fixedly connected to both sides of the adjustment frame, and the outer surface of each limit slider is slidably connected to the inside of the assembly frame.

[0010] The inner bottom wall of the adjustment frame is fixedly connected to two support plates, and the inner wall of each support plate is threaded with a limit bolt.

[0011] Preferably, each of the limiting bolts is fixedly connected to a limiting ball at one end near the sword head body, and the outer surface of each limiting ball is in contact with the outer surface of the sword head body.

[0012] Furthermore, a washer is fitted on the outer surface of the fastening bolt, and the bottom surface of the washer is in contact with the upper surface of the sword head.

[0013] This utility model provides a fixing piece for attaching weft arrowheads, which has the following beneficial effects:

[0014] This type of weft-joining tweezers uses a tweezer body, assembly frame, adjustment frame, fine-tuning screw, auxiliary bearing, support column, fastening bolt, and fastening nut in cooperation with each other. The tweezer body can be initially assembled onto the external weft-joining machine's power structure with other structures. The adjustment frame can slide relative to the assembly frame in a directional manner. With the assistance of the auxiliary bearing, adjusting the fine-tuning screw can temporarily lock the position of the adjustment frame relative to the assembly frame. The tweezer body can rotate around the outer surface of the support column, while the fastening bolt can rotate a small angle along the inner wall of the adjustment frame. After the fastening bolt and fastening nut are tightened, the relative position of the tweezer body and the adjustment frame can be temporarily locked. This allows for fine-tuning of the angle and extension position of the tweezer body even after initial assembly, improving the application scenarios and flexibility of the tweezer body. It avoids the problem of limited application scenarios and limited flexibility caused by the lack of a fine-tuning structure for adjusting the angle and extension position of the weft-joining tweezer structure during actual use.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0024] Please see Figures 1-4This utility model embodiment provides a fixing piece for a weft-joining scissor head, including a scissor head body 1. The scissor head body 1 is a common shape in existing mature technologies. The specific shape and size can be selected according to the actual use scenario. It is mainly used for illustration here. A fixing piece fine adjustment mechanism 2 is provided on the outer side of the scissor head body 1. The fixing piece fine adjustment mechanism 2 includes an assembly frame 201. An adjustment frame 202 is slidably connected inside the assembly frame 201. A fine adjustment screw 203 is threadedly connected to the inner wall of the assembly frame 201. The threaded surface of the fine adjustment screw 203 and the assembly frame 201 has a good friction effect. Without external force to twist the fine adjustment screw 203, the fine adjustment screw 203 will not loosen or shake due to external vibration or other forces. Mounting plates 3 are fixedly connected to both sides of the assembly frame 201. Several identical mounting holes 4 are opened on the upper surface of each mounting plate 3. By setting the mounting holes 4, the mounting plate 3 can be fixedly connected to the action structure of the external weft-joining machine with external bolts, thereby realizing the initial assembly of the scissor head body 1.

[0025] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4 An auxiliary bearing 204 is fixedly connected to the inner wall of the adjusting frame 202. The inner ring of the auxiliary bearing 204 is fixedly connected to the outer surface of the fine-tuning screw 203. Limiting sliders 5 are fixedly connected to both sides of the adjusting frame 202. The outer surface of each limiting slider 5 is slidably connected to the inside of the assembly frame 201. By setting the limiting sliders 5, the adjusting frame 202 can slide back and forth in a directional manner inside the assembly frame 201, thereby increasing the directional and stable sliding of the adjusting frame 202 inside the assembly frame 201 and preventing the adjusting frame 202 from disengaging from the assembly frame 201.

[0026] Please refer to this carefully. Figure 1 , Figure 3 and Figure 4 The inner bottom wall of the adjusting frame 202 is fixedly connected to a support column 205. The outer surface of the support column 205 is rotatably connected to the inner wall of the sword head body 1. The inner bottom wall of the adjusting frame 202 is fixedly connected to two support plates 7. The inner wall of each support plate 7 is threaded with a limit bolt 8. By setting the support plate 7, a threaded travel structure can be provided for the limit bolt 8. The contact thread surface between the limit bolt 8 and the support plate 7 has a good friction effect. Without external force to tighten the limit bolt 8, the limit bolt 8 will not loosen or shake due to external vibration or other forces. By setting the limit bolt 8, it can travel along the inner thread of the support plate 7 and then move closer to or away from the sword head body 1 in conjunction with other limit structures, thereby increasing the stability of the sword head body 1 after angle adjustment.

[0027] Please refer to this carefully. Figure 1 , Figure 3 and Figure 4The inside of the sword head body 1 is provided with fastening bolts 206. The outer surface of the fastening bolts 206 is in contact with the inner wall of the sword head body 1 and the inner wall of the adjusting frame 202 respectively. Each limiting bolt 8 is fixedly connected to a limiting ball 9 at one end near the sword head body 1. The outer surface of each limiting ball 9 is in contact with the outer surface of the sword head body 1. By setting the limiting ball 9, it can move closer to or away from the sword head body 1 as the limiting bolt 8 moves along the inner wall thread of the support plate 7, thereby increasing the stability of the sword head body 1 after angle adjustment and improving the convenience of fine adjustment when adjusting the angle of the sword head body 1.

[0028] Please refer to this carefully. Figure 1 and Figure 4 A fastening nut 207 is fixedly connected to the outer surface of the fastening bolt 206. The top of the fastening nut 207 contacts the bottom surface of the adjusting bracket 202. A washer 6 is fitted on the outer surface of the fastening bolt 206. The bottom surface of the washer 6 contacts the upper surface of the sword head body 1. By setting the washer 6, it can be placed between the fastening bolt 206 and the sword head body 1 and increase the contact area between the two, thereby increasing the fastening effect of the fastening bolt 206.

[0029] When using this utility model: First, the assembly frame 201 is fixed to the power structure of the external weft splicing machine through the mounting holes 4 on the mounting plate 3, thus completing the initial assembly of the sword head body 1.

[0030] When further adjustment of the sword head body 1 is needed, the fine-tuning screw 203 is rotated. Since the auxiliary bearing 204 is fixed to the outer surface of the fine-tuning screw 203, the adjusting frame 202 will slide along the inner wall of the assembly frame 201 as the screw rotates, thereby adjusting the extension and retraction position of the sword head body 1 relative to the sword body. After adjusting to the appropriate position, the thread friction between the fine-tuning screw 203 and the assembly frame 201 can temporarily fix the position of the assembly frame 201.

[0031] The sword head 1 can rotate around the support column 205 to adjust the angle. At the same time, the fastening bolt 206 can rotate within a small range on the inner wall of the adjusting frame 202. The two limiting bolts 8 can also be rotated to make the limiting ball 9 press against the outer surface of the sword head 1 to achieve fine adjustment of the angle of the sword head 1 around the support column 205. After the angle is adjusted, tighten the fastening nut 207 and increase the contact area by the washer 6 to lock the relative position of the sword head 1 and the adjusting frame 202. In addition, rotating the limiting bolt 8 to make the limiting ball 9 press against the outer surface of the sword head 1 further enhances the stability after the angle is adjusted. The design of the fixing piece of the entire weft insertion sword head effectively solves the problem that the lack of a fine-tuning structure for finely adjusting the angle and extension position of the weft insertion sword head structure makes it inconvenient to make fine adjustments in actual use, which limits its application scenarios and the flexibility of use.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
