A weaving equipment for producing grey fabric

Abstract

This utility model discloses a weaving device for producing grey fabric, relating to the field of textile equipment. This device, through the installation of a correction mechanism on one side of the correction roller, allows infrared sensors to monitor the edge position of the grey fabric in real time during operation. When a fabric offset signal is detected, it is immediately transmitted to the correction controller. The correction controller calculates the correction amount according to a preset algorithm and sends a precise displacement command to the servo motor linear driver, driving its output to move the correction roller along the guide rail. The raised structure on the surface of the correction roller effectively increases the friction with the grey fabric, causing the fabric to return to the correct position. After correction is completed, the correction controller automatically sends a reset command, returning the correction roller to its initial position, forming a complete closed-loop control process. Thus, through the setting of the correction mechanism, dynamic real-time correction of the grey fabric position is achieved.

Description

Technical Field

[0001] This utility model relates to the field of textile equipment, specifically a weaving equipment for producing grey fabric. Background Technology

[0002] A loom is a common name for a loom. Early looms were all manually operated. With the development of technology, looms have evolved from manual to automated looms. Modern automated looms mainly include the following parts: warp feeding mechanism, weft insertion mechanism, beat-up mechanism, and take-up mechanism.

[0003] Utility model patent CN216473730U discloses an air-jet weaving equipment for fabric production, comprising a first frame and a second frame arranged sequentially along the process direction. The first frame has a built-in warp roller for pulling warp threads, and the upper part of the second frame is equipped with a traction roller group for pulling fabric, while the lower part is equipped with a winding roller for winding fabric. A weaving table is arranged between the first frame and the second frame, and an air-jet mechanism is arranged on one side of the weaving table. A weft guide table for pulling weft threads is arranged between the air-jet end of the air-jet mechanism and the weaving table. When the weaving efficiency is improved and the speed of the roller group increases, the fabric is transported along the outer periphery of the pressure plate in a "V-shaped" path by adjusting the movement of the pressure plate. This increases the transmission length of the fabric between the traction roller group and the weaving table, preventing the weft threads from slipping, breaking, or winding due to the imbalance of fabric tension caused by the increase in speed, thereby improving the stability of the weaving process.

[0004] However, the weaving equipment only installs a negative pressure vacuum cleaner under the heald frame for single-point dust removal, and lacks an air pump above the heald frame to assist in blowing dust, which makes it impossible for the flying lint to form an effective airflow circulation, resulting in low dust removal efficiency. At the same time, the guide roller is not equipped with a photoelectric correction device. When the fabric deviates by more than 2mm, the roll roller will produce uneven edges like a crooked tape roll, causing subsequent processes to require manual correction. Utility Model Content

[0007] As a preferred embodiment of this utility model, the slider is rotatably connected to one side of the correction roller, a guide rail is slidably connected inside the slider, a servo motor linear driver is rotatably connected to one side of the correction roller, a correction controller is electrically connected to one side of the servo motor linear driver via a power line, an infrared sensor is electrically connected to one side of the correction controller via a power line, and protrusions are provided on the surface of the correction roller.

[0008] As a preferred embodiment of this utility model, the adjusting roller is disposed on the inner side wall of the frame, and both ends of the adjusting roller are rotatably connected to a movable frame. The surface of the movable frame is provided with an adjusting groove, and the frame is provided with two sets of fixing holes on one side of the movable frame. Fixing bolts are connected through the interior of the adjusting groove and the fixing holes, and a fixing nut is threaded to one end of the fixing bolt.

[0009] As a preferred embodiment of this utility model, the air holes are evenly distributed on the inner top of multiple sets of heddle frames. Each set of heddle frames has an airflow channel on one side of the air holes. An air pump is connected through one side of the airflow channel. A solenoid valve is provided at the outlet end of the air pump. A V-shaped groove is provided on the frame directly below the heddle frames. A dust collection box is slidably connected to the bottom of the V-shaped groove. A coarse filter is provided inside the dust collection box. A fine filter is provided below the coarse filter. A negative pressure fan is connected through the bottom of the dust collection box.

[0010] As a preferred embodiment of this utility model, the bottom of the guide rail is threadedly connected to a support frame, and the support frame is threadedly connected to the inner side wall of the frame.

[0011] As a preferred embodiment of this utility model, the servo motor linear driver is connected through the inner wall of the frame, and the infrared sensor is located on one side of the middle of two sets of guide rollers in the same vertical direction.

[0012] As a preferred embodiment of this utility model, the air pump is located on one side of the top of the frame, and the negative pressure fan is connected through the bottom of the V-shaped groove.

[0013] As a preferred embodiment of this utility model, a fabric rolling roller is rotatably connected to the lower inner wall of the frame, a PLC controller is provided on one side of the frame, a display screen is electrically connected to one side of the PLC controller via a power cord, and multiple sets of buttons are provided on one side of the display screen.

[0014] Compared with the prior art, the present invention provides a weaving equipment for producing grey fabric, which has the following beneficial effects:

[0015] This fabric weaving equipment, through a web-correcting mechanism located on one side of the web-correcting roller, uses infrared sensors to monitor the edge position of the fabric in real time during operation. When a web offset signal is detected, it is immediately transmitted to the web-correcting controller. The controller calculates the correction amount based on a preset algorithm and sends a precise displacement command to the servo motor linear driver, driving the output end to move the web-correcting roller along the guide rail. The raised structure on the surface of the web-correcting roller effectively increases the friction with the fabric, causing the fabric to return to the correct position. After correction is complete, the controller automatically sends a reset command, returning the web-correcting roller to its initial position, forming a complete closed-loop control process. Thus, through the web-correcting mechanism, dynamic real-time correction of the fabric position is achieved, ensuring that the fabric wound on the roll-up roller remains neat, effectively improving production quality and efficiency.

[0016] This fabric weaving equipment, through a cleaning mechanism installed on the inner wall of the heald frame, allows the PLC controller to periodically activate the solenoid valve according to a preset program during operation. This drives the air pump to generate compressed air, which flows through the airflow channels and vents inside the heald frame, forming a directional airflow to remove fly shavings and fiber debris from the gaps between the healds. Simultaneously, a negative pressure fan, activated in sync, creates a directional negative pressure field through a V-groove, precisely capturing suspended pollutants in conjunction with the air blowing action. The dust-laden airflow is guided into the dust collection box through the V-groove, where it sequentially passes through a coarse filter to intercept large particles and a fine filter to capture micron-sized dust, achieving graded purification. Finally, the qualified air is discharged through the exhaust port of the negative pressure fan. Thus, through a closed-loop process of "time-sequence control - air blowing stripping - negative pressure collection - graded purification," the production environment is dynamically cleaned while ensuring weaving continuity, significantly reducing the risk of static electricity and production accidents caused by fiber accumulation.

[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 weaving equipment for producing grey fabric, including a frame 1 and multiple sets of guide rollers 2 disposed on the inner side wall of the frame 1. It also includes: a correction roller 3 disposed on one side of one set of guide rollers 2, with a correction mechanism 4 fixedly connected to one side of the correction roller 3. The correction mechanism 4 includes a slider 401, a guide rail 402, a servo motor linear driver 403, a correction controller 404, an infrared sensor 405, and a protrusion 406; and an adjustment mechanism 5 disposed on the inner side wall of the frame 1. The adjustment mechanism 5 includes... The system includes an adjusting roller 501, a movable frame 502, an adjusting groove 503, a fixing hole 504, a fixing bolt 505, and a fixing nut 506; a lifting device 6 is installed above the frame 1, and multiple sets of heddle frames 7 are installed below the lifting device 6. The inner sidewalls of the multiple sets of heddle frames 7 are provided with a cleaning mechanism 8, which includes an air hole, an airflow channel 801, an air pump 802, a solenoid valve 803, a V-groove 804, a dust collection box 805, a coarse filter screen 806, a fine filter screen 807, and a negative pressure fan 808.

[0024] Specifically, the slider 401 is rotatably connected to one side of the correction roller 3, and the slider 401 is slidably connected to the guide rail 402. A servo motor linear driver 403 is rotatably connected to one side of the correction roller 3. A correction controller 404 is electrically connected to one side of the servo motor linear driver 403 via a power line. An infrared sensor 405 is electrically connected to one side of the correction controller 404 via a power line. The surface of the correction roller 3 is provided with protrusions 406.

[0025] In this implementation scheme, during the operation of the weaving equipment, the infrared sensor 405 monitors the edge position of the fabric in real time. When a fabric offset signal is detected, it is immediately transmitted to the correction controller 404. After calculating the correction amount according to a preset algorithm, the correction controller 404 sends a precise displacement command to the servo motor linear driver 403, driving its output to move the correction roller 3 along the guide rail 402. The raised structure 406 designed on the surface of the correction roller 3 effectively increases the friction with the fabric, causing the fabric to return to the correct position. After the correction is completed, the correction controller 404 automatically sends a reset command to return the correction roller 3 to the initial position, forming a complete closed-loop control process.

[0026] Specifically, the adjusting roller 501 is set on the inner side wall of the frame 1. Both ends of the adjusting roller 501 are rotatably connected to the movable frame 502. The surface of the movable frame 502 is provided with an adjusting groove 503. The frame 1 is provided with two sets of fixing holes 504 on one side of the movable frame 502. The adjusting groove 503 and the fixing hole 504 are both connected through a fixing bolt 505. One end of the fixing bolt 505 is threaded with a fixing nut 506.

[0027] In this implementation scheme, during operation, the fixing bolt 505 is first loosened, and the moving frame 502 is pushed to slide horizontally through the adjusting groove 503. After positioning, the fixing bolt 505 is tightened again. This displacement is transmitted to the adjusting roller 501 through the rigid connection mechanism 1:1, causing it to move in the same direction. As a key actuator for tension control, the horizontal change of the position of the adjusting roller 501 will change the warp wrap angle, thereby realizing the linear adjustment of the warp tension of the fabric. When the adjusting roller 501 moves to the left, the warp tension increases, and when it moves to the right, the tension decreases.

[0028] Specifically, air holes are evenly distributed on the inner top of multiple sets of heddle frames 7. An airflow channel 801 is provided on one side of the air holes in the multiple sets of heddle frames 7. An air pump 802 is connected through one side of the airflow channel 801. A solenoid valve 803 is provided at the outlet end of the air pump 802. A V-shaped groove 804 is provided on the frame 1 directly below the heddle frame 7. A dust collection box 805 is slidably connected to the bottom of the V-shaped groove 804. A coarse filter 806 is provided inside the dust collection box 805. A fine filter 807 is provided below the coarse filter 806. A negative pressure fan 808 is connected through the bottom of the dust collection box 805.

[0029] In this implementation scheme, when the weaving equipment is running, the PLC controller 11 starts the solenoid valve 803 according to the preset program at regular intervals, driving the air pump 802 to generate compressed air. The airflow passes through the airflow channel 801 and air holes inside the heddle frame 7, forming a directional airflow to remove fly shavings and fiber debris from the gaps between the heddles. At the same time, the negative pressure fan 808 starts synchronously and forms a directional negative pressure field through the V-groove 804. Combined with the air blowing action, it accurately captures suspended pollutants. The dust-laden airflow is guided into the dust collection box 805 through the V-groove 804, and then passes through the preliminary coarse filter 806 to intercept large particles and the precision fine filter 807 to capture micron-sized dust, achieving graded purification treatment. Finally, the qualified air is discharged through the exhaust port of the negative pressure fan 808.

[0030] Specifically, the bottom of the guide rail 402 is threadedly connected to a support frame 9, which is threadedly connected to the inner wall of the frame 1.

[0031] In this embodiment, the support frame 9 serves as a load-bearing component, providing stable support for the guide rail 402 through its rigid structure.

[0032] Specifically, the servo motor linear driver 403 is connected through the inner wall of the frame 1, and the infrared sensor 405 is set on one side of the middle of the two sets of guide rollers 2 in the same vertical direction.

[0033] In this embodiment, the two sets of guide rollers 2 are in the same vertical direction, so that the fabric maintains the consistency of the edge position during the process. The infrared sensor 405 is installed at the monitoring position of the standard edge of the fabric in an orthogonal detection manner, and detects the offset of the fabric edge in real time by emitting and receiving infrared beams.

[0034] Specifically, the air pump 802 is located on one side of the top of the frame 1, and the negative pressure fan 808 is connected through the bottom of the V-shaped groove 804.

[0035] In this embodiment, the air pump 802 removes fiber debris from the gaps between the heddles in the heddle frame 7 by directional airflow jet, causing suspended particles to detach from the working surface. At the same time, the negative pressure fan 808 configured at the bottom of the V-groove 804 forms a local negative pressure zone, which quickly draws the debris blown away by the air pump 802 into the dust collection box 805.

[0036] Specifically, a cloth rolling roller 10 is rotatably connected to the lower inner wall of frame 1, a PLC controller 11 is provided on one side of frame 1, a display screen 12 is electrically connected to one side of PLC controller 11 via a power cord, and multiple sets of buttons 13 are provided on one side of display screen 12.

[0037] In this implementation scheme, the fabric roll 10 is the execution terminal responsible for the automatic winding and collection of finished fabric, the PLC controller 11 is the core control unit, and the start-stop sequence and operating parameters of each electronic device are precisely coordinated through programming logic. The display screen 12 presents key parameters such as loom speed, production count, and fault codes in real time with a visual interface, and the physical button 13 provides a human-machine interface for basic operations such as emergency stop and mode switching.

[0038] In summary, this fabric weaving equipment for producing grey fabric achieves dynamic real-time correction of the grey fabric position through the setting of the correction mechanism 4 on one side of the correction roller 3 and the cleaning mechanism 8 on the inner side wall of the heald frame 7. This ensures that the grey fabric wound on the surface of the roll roller 10 remains neat, effectively improving production quality and efficiency. At the same time, while ensuring weaving continuity, it also achieves dynamic cleaning of the production environment, significantly reducing the risk of static electricity caused by fiber accumulation and the rate of production accidents.
