[0018] 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.

[0019] Please see Figure 1-3This embodiment provides a multi-arm jacquard device for a loom, including a mounting base 100. A jacquard needle 104 is mounted on the bottom of the mounting base 100. A mounting ring 101 is fixedly sleeved on the outer circular surface of the mounting base 100. Square grooves 102 are opened at the four corners of the bottom of the mounting ring 101. T-shaped connecting arms 103 are provided in the inner cavity of the four sets of square grooves 102. An anti-detachment component for sealing the lower opening of the square grooves 102 and preventing the head of the T-shaped connecting arm 103 from falling off is connected to the bottom of the mounting ring 101 by a fixing component. A spring 106 is provided at the top of each set of T-shaped connecting arms 103. A connecting ring 205 is provided at the top of each set of springs 106. An adjusting component for adjusting the elasticity of each set of springs 106 according to the thickness of the fabric is provided on the outer circular surface of the mounting base 100. A set of clamping rings 105 is fixedly connected to the bottom of the four sets of T-shaped connecting arms 103.

[0020] The adjusting component includes an adjusting ring 201 disposed on the outer circular surface of the mounting ring 101. Each set of connecting rings 205 is fixedly connected to the outer side of a connecting strip 204. The outer side of each set of connecting strips 204 is fixedly connected to the corresponding inner wall of the adjusting ring 201. The outer circular surface of the mounting ring 101 is provided with a pushing component for moving the adjusting ring 201 up and down. By setting the adjusting component, the adjusting ring 201 is moved up and down by the pushing component, thereby driving the connecting ring 205 to move up and down together. This adjusts the elasticity of the spring 106 according to the fabric thickness, so that the device can adapt to fabrics of different thicknesses and improve the adaptability of jacquard operation.

[0021] The pusher includes an external thread 202 on the outer surface of the mounting ring 101. An internal thread ring 200 is threadedly connected to the outer surface of the mounting ring 101 via the external thread 202. The bottom of the internal thread ring 200 is connected to the top of the adjusting ring 201 via an adapter. By rotating the internal thread ring 200, the adjusting ring 201 can be moved up and down smoothly. The threaded connection allows for precise control of the movement of the adjusting ring 201, thereby accurately adjusting the elasticity of the spring 106 and improving the accuracy and reliability of the adjustment.

[0022] The adapter includes an adapter ring 203 fixedly connected to the top of the adjusting ring 201. The head of the adapter ring 203 is rotatably connected to the bottom of the internal threaded ring 200. The cross-section of the adapter ring 203 is T-shaped. By using the T-shaped adapter ring 203, the internal threaded ring 200 and the adjusting ring 201 are rotatably connected. This ensures that the internal threaded ring 200 does not drive the adjusting ring 201 to rotate synchronously when it rotates, but only drives the adjusting ring 201 to move up and down. This ensures the single direction of movement of the adjusting ring 201 and improves the stability of the adjustment process.

[0023] The outer surface of the internal threaded ring 200 is provided with anti-slip texture 109. The anti-slip texture 109 increases the friction force when the operator rotates, making it easier to apply force and making the rotation operation of the internal threaded ring 200 more convenient and labor-saving, thus improving the convenience of adjustment operation.

[0024] The anti-detachment component includes a blocking ring 300 embedded in the opening of each set of square grooves 102. A set of fixing rings 301 is fixedly connected to the bottom of the four sets of blocking rings 300. By setting the anti-detachment component, the blocking rings 300 are embedded in the opening of the square grooves 102 and connected with the fixing rings 301, which can effectively limit the T-shaped connecting arm 103, reliably prevent the T-shaped connecting arm 103 from falling out of the square grooves 102, and ensure the stable operation of the T-shaped connecting arm 103 and the clamping ring 105 and other components.

[0025] The fasteners include four sets of fixing bolts 302 inserted into the bottom of the fixing ring 301. The bolts of the four sets of fixing bolts 302 pass upward through the fixing ring 301 and are threaded to the bottom of the mounting ring 101. By setting the fasteners and using the fixing bolts 302 to connect the fixing ring 301 and the mounting ring 101, the connection between the anti-detachment component and the mounting ring 101 can be ensured, and the anti-detachment effect can be ensured. At the same time, it is easy to disassemble the fixing bolts 302, which provides convenience for the maintenance or replacement of subsequent components such as the T-shaped connecting arm 103 and the spring 106, and improves the maintainability of the device.

[0026] The top inner walls of the four sets of square grooves 102 are respectively fixedly connected with guide rods 107. The ends of the four sets of guide rods 107 pass through the connecting ring 205, the blocking ring 300, and the fixing ring 301 respectively and are slidably inserted into the inner cavity of the T-shaped connecting arm 103. Through the setting of the guide rods 107, the guide rods 107 pass through the relevant components and are slidably inserted into the inner cavity of the T-shaped connecting arm 103, which can play a precise guiding role in the up and down movement of the T-shaped connecting arm 103, effectively preventing the T-shaped connecting arm 103 from deviating during the movement, ensuring that the T-shaped connecting arm 103 always moves in a straight line, thereby ensuring the stability of the spring 106 adjustment and the reliability of the jacquard needle 104 operation.

[0027] Working principle: First, the top of the mounting base 100 is connected to the operating end of the loom. When jacquard operation is required, the operating end of the loom pushes the mounting base 100 downward. The clamping ring 105 below the mounting base 100 contacts the surface of the fabric in advance. As the mounting base 100 moves downward, the T-shaped connecting arm 103 at the top of the clamping ring 105 compresses the spring 106 in the square groove 102, tensioning the fabric. Then, the jacquard needle 104 performs jacquard operation on the fabric. When it is necessary to adjust the elasticity of the spring 106 according to the fabric thickness, the inner thread ring 200 is rotated. The anti-slip texture 109 on its outer surface increases the friction and facilitates operation. The inner thread ring 200 will move up and down along the outer surface of the mounting ring 101. Since the bottom of the inner thread ring 200 is connected to the top of the adjusting ring 201 through the adapter ring 203, the up and down movement of the inner thread ring 200 will drive the adjusting ring 201 to move up and down synchronously.

[0028] When the adjusting ring 201 moves up and down, it drives the connecting ring 205 to move synchronously through the connecting strip 204, thereby changing the compression of the spring 106. When the adjusting ring 201 moves up, the compression of the spring 106 decreases and the elasticity weakens. When the adjusting ring 201 moves down, the connecting ring 205 moves down, causing the spring 106 to be compressed and the elasticity to increase. Through this adjustment, the force exerted by the spring 106 on the T-shaped connecting arm 103 changes accordingly, ultimately enabling the jacquard needle 104 at the bottom of the mounting base 100 to adapt to fabrics of different thicknesses, ensuring the stability and adaptability of the jacquard operation.

[0029] Furthermore, the guide rod 107, fixed to the inner wall of the top of the square groove 102, passes downward through the relevant components and slides into the inner cavity of the T-shaped connecting arm 103. When the T-shaped connecting arm 103 moves up and down under the force of the spring 106 or external force, the guide rod 107 plays a precise guiding role, preventing the T-shaped connecting arm 103 from deviating and ensuring that it always moves in a straight line, further ensuring the stability of the adjustment of the spring 106 and the reliability of the operation of the jacquard needle 104.

[0030] When the elastic potential energy of spring 106 decreases after prolonged use, the four sets of fixing bolts 302 are disassembled in sequence, and the fixing ring 301 is moved downward to cause the blocking ring 300 to fall off the opening of the corresponding side square groove 102. At this time, the clamping ring 105 is moved downward to cause the four sets of T-shaped connecting arms 103 to disengage from the inner cavity of the square groove 102, thereby releasing the restriction on spring 106. The old spring 106 is removed, and the new spring 106 is fitted onto the surface of guide rod 107. The upper openings of the four sets of T-shaped connecting arms 103 are slidably inserted into the surface of guide rod 107. Then, the fixing ring 301 is moved upward so that the four sets of blocking rings 300 are respectively embedded in the opening of the square groove 102. Then, the four sets of fixing bolts 302 are used to penetrate the fixing ring 301 upward and threadedly connect the bottom of the mounting ring 101.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
