A new rapier head for a rapier loom

Abstract

This utility model discloses a novel rapier loom sling head, relating to the technical field of rapier loom sling heads. The novel rapier loom sling head includes a rapier body. Through the arrangement of a connecting mechanism and a buffer mechanism, the rapier body reciprocates within the outer casing during use. A connecting plate on one side of the rapier body is connected to a rotating block via a pin. The rotating block rotates on a central positioning post, and the reciprocating motion of the rapier body is achieved in conjunction with a torsion spring mounted on the surface of the positioning post. Furthermore, a buffer groove is formed on one side of the connecting plate, which is adapted to a buffer spring on one side. During the reciprocating motion, the buffer groove compresses the buffer spring on one side, utilizing the counterforce provided by the buffer spring to reduce the impact force during the reciprocating motion, transforming rigid collision into elastic deformation, and preventing damage to the sling head component due to excessive impact force.

Description

Technical Field

[0001] This utility model relates to the field of rapier loom connector technology, specifically a novel rapier loom connector. Background Technology

[0002] In the weaving process of a rapier loom, the rapier head, as a core component, undertakes the key functions of receiving, transmitting, and transferring weft yarns. Its performance directly affects the weaving efficiency, operational stability, and fabric quality of the loom.

[0003] The existing rapier loom's rapier joint head has significant shortcomings in practical applications. During the rapier joining process, the connection between the rapier and the joint head generates a large impact force. Traditional joint heads lack an effective buffer structure, and long-term exposure to rigid impacts easily leads to accelerated wear of components, shortens service life, and increases equipment maintenance costs and downtime. Therefore, a new type of rapier loom joint head has been proposed. Utility Model Content

[0004] This invention provides a novel rapier loom connector to address the problem that the connection between the existing rapier and the connector generates a large impact force, and that traditional connectors lack an effective buffer structure. Long-term exposure to rigid impacts can easily lead to accelerated wear of components, shorten service life, and increase equipment maintenance costs and downtime.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model discloses a new type of rapier loom's rapier head, including a rapier body 1, and further comprising:

[0024] A connecting plate 2 is provided on one side of the main body 1 of the sword shaft. A pin 3 is fixedly connected to the bottom of the connecting plate 2. A connecting mechanism 4 is inserted into the bottom of the pin 3. The connecting mechanism 4 includes a rotating block 401, a positioning pin 402, an upper cover plate 403, and an anti-loosening threaded hole 404.

[0025] A buffer groove is provided on one side of the connecting plate 2, and a buffer mechanism 5 is provided on one side of the buffer groove. The buffer mechanism 5 includes a buffer spring 501 and a connecting block 502.

[0026] Specifically, the rotating block 401 is inserted into the surface of the pin 3. A limiting hole is opened in the middle of the rotating block 401. A positioning pin 402 is rotatably connected inside the limiting hole. An upper cover plate 403 is threadedly connected to the surface of the positioning pin 402. An anti-loosening threaded hole 404 is opened on the surface of the upper cover plate 403.

[0027] In this embodiment, when in use, the sword shaft body 1 will reciprocate inside the outer shell 6. Since the bottom of the connecting plate 2 on one side of the sword shaft body 1 is connected to the rotating block 401 through the pin 3, the rotating block 401 rotates on the central positioning post 402, and cooperates with the torsion spring installed on the surface of the positioning post 402 to realize the reciprocating motion of the sword shaft body 1.

[0028] Specifically, the buffer spring 501 is located on one side of the buffer groove, and a connecting block 502 is fixedly connected to one side of the buffer spring 501.

[0029] In this embodiment, a buffer groove is provided on one side of the connecting plate 2. The buffer groove is adapted to the buffer spring 501 on one side. During the reciprocating motion, the buffer groove squeezes the buffer spring 501 on one side.

[0030] Specifically, a torsion spring is provided on the surface of the positioning post 402, and both sides of the torsion spring are fixedly connected to the inside of the rotating block 401.

[0031] In this embodiment, the torsion spring facilitates the reciprocating rotation of the positioning post 402 surface of the rotating block 401.

[0032] Specifically, the bottom of the connecting block 502 is threadedly connected to the outer shell 6, and the top center of the sword shaft body 1 is snapped with a limit cover 7.

[0033] Specifically, a hook head 8 is fixedly connected to the end of the sword shaft body 1, and the hook head 8 is made of alloy steel.

[0034] In this embodiment, the outer shell 6 facilitates the support and fixation of the internal structure, the hook head 8 facilitates hooking the line, and the limiting cover 7 facilitates the limiting of the sword shaft body 1, reducing shaking.

[0035] Specifically, an alloy steel 9 is fixedly connected inside the outer casing 6, and the alloy steel 9 is located on the side near the hook head 8.

[0036] Specifically, the positioning post 402 has a threaded hole inside, and a threaded post 10 is connected to the threaded hole inside. A silicone pad 11 is attached to one side of the sword body 1.

[0037] The working principle and usage process of this utility model are as follows: When in use, the sword shaft body 1 will reciprocate inside the outer shell 6. Since the bottom of the connecting plate 2 set on one side of the sword shaft body 1 is connected to the rotating block 401 through the pin 3, the rotating block 401 rotates on the central positioning post 402, and cooperates with the torsion spring installed on the surface of the positioning post 402 to realize the reciprocating motion of the sword shaft body 1. Secondly, a buffer groove is opened on one side of the connecting plate 2. The buffer groove is adapted to the buffer spring 501 on one side. During the reciprocating motion, the buffer groove squeezes the buffer spring 501 on one side.

[0038] In summary, the rapier loom's rapier head, through the connection mechanism 4 and the buffer mechanism 5, utilizes the reverse force provided by the buffer spring 501 to reduce the impact force during reciprocating motion, transforming rigid collision into elastic deformation, and preventing the rapier head from being damaged due to excessive impact force.
