Detailed Implementation

[0021] 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. Example 1:

[0022] like Figure 1-3 As shown, the present invention discloses a jacquard loom for imitation brocade fabric, including a loom body 1, a double-layer jacquard mechanism 2 at the top of the loom body 1, a yarn guide and float adjustment component 3 between the double-layer jacquard mechanism 2 and the loom body 1, a warp feeding component 4 on the loom body 1, a control terminal 5 on one side of the loom body 1, and a pattern changing component 6 embedded in the top plate of the loom body 1.

[0023] The double-layer jacquard mechanism 2 includes uprights 201 on both sides of the top of the loom body 1, which are bolted together to enhance structural stability. Each upright 201 is hollow and has a vertical guide groove inside. A guide slide 202 is slidably installed in the guide groove and can move up and down along the vertical direction of the upright 201 to achieve precise control of the jacquard movement. A lower needle plate 203 and an upper needle plate 204 are fixedly connected to the top of the guide slide 202 from bottom to top. The upper needle plate 204 is fixed to the upper part of the guide slide column 202 by a nut connection. It is used to support and drive the movement of the jacquard needles. The top surface of the upper needle plate 204 is covered with a protective cover 205. The protective cover 205 is fixed to the top end face of the column 201 by bolts. It is used to protect the jacquard needle plate from external dust, fiber debris and human error. At the same time, it provides a safe operating space for equipment maintenance personnel. It is equipped with ventilation holes to facilitate the heat dissipation of the jacquard mechanism during operation and improve the stability and safety of the whole machine operation.

[0024] The upper needle lifting plate 204 is equipped with drive motors on both sides of its top end. The drive motors are connected to the guide slide column 202 and are used to drive the guide slide column 202 to move up and down within the column 201, thereby driving the needle lifting action. The upper needle lifting plate 204 is equipped with a needle lifting plate slide rail groove at its top end. The needle lifting plate slide rail groove is used to fix the needle on the upper needle lifting plate 204. The needle is equipped with a sensor. The needle fixing technology is existing technology and will not be described in detail here.

[0025] The yarn guide and float adjustment assembly 3 includes a yarn guide slide rail seat 301 located at one end of the top surface of the loom body 1. The yarn guide slide rail seat 301 has a long strip structure and is securely installed on the front top frame plate of the loom body 1 by screw fixing. A positioning groove is provided at its bottom to ensure precise and symmetrical installation. A pair of slidingly engaging moving blocks 302 are symmetrically arranged on the yarn guide slide rail seat 301. The moving blocks 302 are slidably connected to the yarn guide slide rail seat 301 through the slide rail groove at their bottom, and can reciprocate along the lateral direction of the slide rail seat to meet the needs of adjusting different warp yarn guide spacings. A yarn guide crossbar 303 is inserted between the pair of moving blocks 302. The yarn guide crossbar 303 is a hollow metal tubular structure with positioning slots at both ends, and is engaged with the moving blocks 302 by fastening bolts. The movable block 302 is securely connected, allowing the yarn guide bar 303 to move as a whole with the movable block 302, thus achieving lateral adjustment of the yarn guide position. Multiple sets of yarn guide rings 304 are sleeved on the yarn guide bar 303. The yarn guide rings 304 are evenly distributed at a certain interval and can all rotate freely. They are used to guide each warp yarn to pass smoothly and maintain stable yarn separation, preventing tangling, crossing, or yarn skipping. At the end of the top surface of the loom body 1 opposite to the yarn guide slide rail seat 301, a floating tension bar assembly 305 is provided. The floating tension bar assembly 305 is a centrally protruding part used to generate a certain tension feedback with the warp yarn, so that the warp yarn entering the jacquard area is kept taut, ensuring that the yarn tension is balanced and the pattern is clear during the jacquard weaving process. The floating tension bar assembly 305 is a common component, and its structure will not be described in detail here.

[0026] The warp feeding assembly 4 includes a warp feeding motor 401, which is located on one side of the loom body 1. The outer side of the loom body 1 is connected from top to bottom to an active traction roller 402 and a driven traction roller 403. The rotating shaft of the active traction roller 402 is connected to the warp feeding motor 401 through a synchronous belt 404.

[0027] The warp feeding assembly 4 includes a warp feeding motor 401 disposed on one side of the loom body 1. The warp feeding motor 401 is a servo motor or stepper motor with high-precision speed regulation capability, and is fixed to a motor mounting plate on the outer side wall of the loom body 1 by a mounting base. From top to bottom, the outer side of the loom body 1 is provided with an active traction roller 402 and a driven traction roller 403, both of which are fixed to roller mounting blocks on the side frame of the loom body 1 by vertical brackets. The active traction roller 402 has a hollow steel shaft structure, with an outer surface covered with a non-slip and wear-resistant rubber layer. One end of its rotating shaft is provided with a synchronous pulley for cooperating with a synchronous belt 404. The synchronous belt 404 is a toothed belt. The gears on the output shaft of motor 401 mesh with each other, effectively preventing slippage during transmission and improving the accuracy and consistency of the warp feeding process. The driven traction roller 403 is located below the active traction roller 402 and is fixedly connected to the loom body 1 through an adjustable tensioning mechanism. The tensioning mechanism consists of a sliding support, a return spring, and an adjusting bolt, allowing the driven roller to be finely adjusted up and down to adapt to different warp tension and thickness variations, thereby improving the adaptability and operational stability of the warp feeding system. During the warp feeding process, the warp yarn is guided from the cloth roll to the active traction roller 402 through the yarn guiding system and forms a clamping structure with the driven traction roller 403. The friction between the rollers achieves uniform warp feeding.

[0028] The pattern changing component 6 includes a template groove on one side of the top plate of the loom body 1. A pattern template piece is inserted into the template groove. The pattern template piece is provided with perforation codes. How the pattern changing component is embedded in the loom body 1 is conventional technology and will not be described in detail. The perforation codes on the pattern template piece indicate whether a perforation is performed or not. They correspond to the sensors on the lifting needle. When the lifting needle senses that the perforation code indicates a perforation action, the lifting needle is lifted. When the lifting needle senses that the perforation code indicates a non-perforation action, the lifting needle does not move.

[0029] The control terminal 5 includes a control main board located on the outside of the loom body 1. The control main board is logically connected to the pattern template sheet. The control main board is used to read the pattern and perforation code on the pattern template sheet to facilitate the control of the lifting needle for perforation guidance. The control main board and the active traction roller 402 are located on the opposite side of the loom body 1. The control main board is electrically connected to a control panel 501, which is located on the right side of the loom body 1. The control panel 501 and the warp feed motor 401 are located on the opposite side of the loom body 1.

[0030] Working Principle: During operation, the control terminal 5 first reads the perforation code information on the pattern template in the pattern changing component 6, distinguishes between perforated and non-perforated patterns through logical judgment, and transmits this information to the control system of the double-layer jacquard mechanism 2. The control system, based on the read pattern instructions, drives the servo motors located on both sides of the column 201, thereby moving the guide slide column 202 up and down along the vertical guide groove. This, in turn, drives the upper needle plate 204 and lower needle plate 203 to generate corresponding needle lifting actions. When the needle lifting sensor detects that the perforation code on the template is "perforated," the corresponding needle is lifted, causing the corresponding warp yarn to float and form the pattern outline. If it is detected as "non-perforated," the needle does not move, the warp yarn remains in its original position, and the background weaving is completed. Simultaneously, the warp feeding motor 401 in the warp feeding component 4 precisely drives the active traction roller 402 to rotate according to the control instructions, and achieves stable transmission through the synchronous belt 404 and toothed meshing. The driven traction roller 403, under the action of the tensioning mechanism, clamps and conveys the warp yarn, achieving stable warp feeding. The warp yarns are guided from the fabric roll through the guide ring 304 on the guide rail seat 301 into the jacquard area. The guide bar 303 and the float tension bar 305 work together to ensure that the yarns are neatly arranged and the tension is moderate, avoiding yarn skipping or tangling. The various functional modules of the entire system work together to ensure that the pattern changes are flexible, the jacquard action is precise, and the warp feed is stable and reliable during the weaving process, meeting the comprehensive requirements of imitation jacquard fabric weaving for complex patterns, high-precision forming, and stable operation.
