Description

Technical Field

[0001] This utility model relates to a weft insertion rapier head, specifically a sliding rapier loom weft insertion rapier head, belonging to the field of textile machinery technology. Background Technology

[0002] Rapier looms are a common type of textile machinery. The weft insertion rapier, as a key component of rapier looms, is mainly used in textile machinery for yarn clamping and unwinding. Its performance directly affects the weaving quality and efficiency of the loom.

[0003] In the operation of sliding rapier looms, the weft insertion rapier, as a key component, requires frequent adjustment, maintenance, and replacement. Traditionally, the connection between the weft insertion rapier and the rapier shaft is achieved through bolt fastening. This method requires tools to tighten each bolt individually during installation and disassembly, which is cumbersome, time-consuming, and severely impacts equipment maintenance efficiency. Furthermore, bolted connections are prone to loosening and slippage after prolonged use, leading to a decrease in the positioning accuracy of the weft insertion rapier and affecting weaving quality. Therefore, this paper proposes a new weft insertion rapier for sliding rapier looms. Utility Model Content

[0004] This invention proposes a sliding rapier loom weft insertion rapier head to solve the problem of cumbersome installation and disassembly in the prior art.

[0005] This utility model is achieved through the following technical solution: a sliding rapier loom weft insertion rapier head, including a rapier body, wherein a quick disassembly and assembly mechanism is provided inside the rapier body;

[0006] The quick-assembly and disassembly mechanism includes a mounting base. The left side of the mounting base is fixedly connected to the right end of the sword shaft body. The sword head body is slidably connected inside the mounting base. Two protrusions are slidably connected inside the sword head body. A return spring is fixedly connected to the side of the two protrusions that are close to each other. The ends of the two return springs that are close to each other are fixedly connected to the inner wall of the sword head body. Two force-bearing plates are slidably connected inside the mounting base. Auxiliary grooves are provided on the upper and lower surfaces of the mounting base.

[0007] A reinforcing ring is fixedly connected to the outer surface of the sword shaft body, and the right end of the reinforcing ring is fixedly connected to the left side of the mounting base.

[0008] A sliding block is fixedly connected to the front of the sword head body, and the sliding block is slidably connected to the inside of the mounting base.

[0009] Each of the protrusions has a stabilizing block fixedly connected to its left side, and each stabilizing block is slidably connected to the inside of the sword head body.

[0010] Each of the force-bearing plates has a limiting block fixedly connected to its front and back sides, and each limiting block is slidably connected to the inside of the mounting base.

[0011] The outer surface of the sword shaft body is fitted with a reinforcing layer, and the outer surface of the reinforcing layer is fitted with a wear-resistant layer.

[0012] This utility model provides a sliding rapier loom weft insertion rapier head, which has the following beneficial effects:

[0013] This sliding rapier loom uses a weft insertion rapier head. It comprises a rapier body, a mounting base, a rapier head body, a protrusion, a return spring, an auxiliary groove, and a force-bearing plate. The rapier head body can be inserted into the mounting base. Simultaneously, when the protrusion is subjected to pressure from the mounting base, it gradually retracts into the rapier head body, while the return spring is compressed. When the protrusion reaches the designated position, it returns to its original position within the pre-drilled groove in the mounting base due to the spring force, thus locking the rapier head body in its position within the mounting base. This allows for quick installation of the rapier body and the rapier head body. Insert the external push rod into the auxiliary slot and push the two force plates closer to each other. Relying on the force plates, the protrusion is pushed back into the rapier body, thereby releasing the limiting relationship of the protrusion and quickly removing the rapier body from the rapier shaft body. This solves the problem that the traditional connection method between the weft insertion rapier head and the rapier shaft mostly uses bolt fastening. It prevents the need to use tools to tighten the bolts one by one during installation and disassembly, which is cumbersome and time-consuming. It also avoids the situation where bolt connections are prone to loosening and stripping after long-term use, which leads to a decrease in the positioning accuracy of the weft insertion rapier head. This plays a role in increasing the weaving quality. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-4 This utility model provides a sliding rapier loom weft insertion rapier head, including a rapier body 1, and a quick disassembly and assembly mechanism 2 is provided inside the rapier body 1;

[0024] The quick-release mechanism 2 includes a mounting base 201. The left side of the mounting base 201 is fixedly connected to the right end of the sword shaft body 1. A reinforcing ring 3 is fixedly connected to the outer surface of the sword shaft body 1. The right end of the reinforcing ring 3 is fixedly connected to the left side of the mounting base 201. The reinforcing ring 3 can increase the fixed connection area between the sword shaft body 1 and the mounting base 201, thereby making the connection between the two more secure, preventing the possibility of breakage at the connection after long-term use, and increasing the robustness of the device.

[0025] The mounting base 201 is internally slidably connected to the sword head body 202. The front of the sword head body 202 is fixedly connected to the sliding block 4. The sliding block 4 is slidably connected to the inside of the mounting base 201. The sliding block 4 can move simultaneously with the sword head body 202 and uses the friction generated by itself on the mounting base 201 during the movement to improve the stability of the sword head body 202 when it moves, thereby increasing the stability of the device.

[0026] The sword tip body 202 has two protrusions 203 slidably connected inside. Each protrusion 203 has a stabilizing block 5 fixedly connected to its left side. Each stabilizing block 5 is slidably connected inside the sword tip body 202. The stabilizing block 5 can move simultaneously with the protrusion 203 and use the friction generated by itself on the sword tip body 202 during the movement to improve the stability of the protrusion 203 when it moves, thus further increasing the stability of the device.

[0027] Two protrusions 203 are fixedly connected to a return spring 204 on their adjacent sides. The two return springs 204 are fixedly connected to the inner wall of the sword head body 202 at their adjacent ends. Two force plates 206 are slidably connected inside the mounting base 201. Limiting blocks 6 are fixedly connected to the front and back of each force plate 206. Each limiting block 6 is slidably connected inside the mounting base 201. The limiting block 6 can move simultaneously with the force plate 206 and use the friction generated by itself on the mounting base 201 during the movement to improve the stability of the force plate 206 when it moves. At the same time, it can also limit the movement distance of the force plate 206.

[0028] The upper and lower surfaces of the mounting base 201 are provided with auxiliary grooves 205. The outer surface of the sword shaft body 1 is covered with a reinforcing layer 7, and the outer surface of the reinforcing layer 7 is covered with a wear-resistant layer 8. The reinforcing layer 7 can increase the overall hardness of the sword shaft body 1 and extend the service life of the sword shaft body 1. The wear-resistant layer 8 can reduce the wear resistance of the sword shaft body 1 and further improve the service life of the sword shaft body 1.

[0029] When using this utility model: when it is necessary to install the weft-jointing sword head, first align the mounting seat 201 at the rear end of the sword shaft body 1 with the sword head body 202, and then push the sword head body 202 so that the sword head body 202 is slowly inserted into the mounting seat 201. During the insertion process, the wedge-shaped end of the mounting seat 201 will contact the inclined surface of the protrusion 203. After being squeezed, the protrusion 203 will overcome the elastic force of the return spring 204 and retract into the sword head body 202. When the sword head body 202 is fully inserted into the mounting seat 201, the protrusion 203 will correspond to the pre-reserved hole slot position of the mounting seat 201. Under the action of the return spring 204, the protrusion 203 will pop out and then be inserted into the hole slot of the mounting seat 201, thereby realizing a firm connection between the sword head body 202 and the sword shaft body 1.

[0030] When disassembling the rapier head body 202, the operator only needs to insert an external object into the auxiliary groove 205 and press down. At this time, the force plate 206 will push the protrusion 203 to retract due to the pressure. At the same time, the limiting block 6 can improve the uniformity of the force when the force plate 206 moves, so that the protrusion 203 is completely retracted into the rapier head body 202 and the limiting relationship of the protrusion 203 is released. At this time, the rapier head body 202 can be easily pulled out from the rapier body 1 and the disassembly operation is completed, which effectively increases the performance of the weft insertion rapier head for sliding rapier looms.

[0031] 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.
