Description

Technical Field

[0001] The utility model relates to the field of textile processing, in particular to a feeding mechanism for textile processing with adjustable feeding speed. Background Art

[0002] The textile industry is an industrial sector that processes natural fibers and chemical fibers into various yarns, silks, threads, ribbons, fabrics and their dyed and finished products. Among them, the feeding mechanism is an important device in the textile processing process. All the thread groups in the textile process are usually wound on the thread feeding mechanism. The feeding speed of the thread groups is uniformed through automation. However, since the thread groups on each wire roll cannot maintain the same tension on the entire thread group, some thread groups will unwind faster and some will unwind slower when feeding and unwinding. As a result, some thread groups will be relaxed and some will be tight when unwinding, and the quality of textiles cannot be strictly controlled.

[0003] Therefore, it is necessary to provide a new feeding mechanism for textile processing with adjustable feeding speed to solve the above-mentioned technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a feeding mechanism for textile processing with adjustable feeding speed.

[0005] The feeding mechanism for textile processing with adjustable feeding speed provided by the utility model comprises:

[0006] A fixed frame, there are several fixed frames, and several fixed frames are combined together, and the number of fixed frames corresponds to the number of spinning lines;

[0007] The sliding frame is slidably mounted on the top of the fixed frame, a mounting plate is fixedly mounted in the middle of the sliding frame, a pressure sensor for detecting the tightness of the spinning thread is fixedly mounted on the lower surface of the mounting plate, the spinning thread is below the detection end of the pressure sensor, the pressure sensor is electrically connected to a controller for controlling the feeding of the spinning thread, the controller is electrically connected to a motor for controlling the feeding here, sliders are symmetrically fixedly mounted on both sides of the sliding frame, and slide grooves are symmetrically opened on both sides of the top of the fixed frame, and the sliders are slidably connected to each other. When the device is in use, the spinning thread is set below the detection end of the pressure sensor, and the slack and tightness of the spinning thread are detected by the pressure sensor. The pressure sensor transmits this signal to the controller, and the controller controls the output shaft of the motor for feeding here to slow down or speed up the rotation, so as to achieve precise adjustment of the feeding speed.

[0008] Preferably, a first guide wheel is rotatably mounted on one end of the sliding frame through an axle pin, and a second guide wheel is rotatably mounted on the other end of the sliding frame through an axle pin, the spinning thread is placed in the gap between the first guide wheel and the second guide wheel, the first guide wheel and the second guide wheel are used to horizontally place the feeding and discharging of the spinning thread, and the detection end of the pressure sensor is slightly lower than the middle of the first guide wheel and the second guide wheel. When placing the spinning thread, passing the spinning thread under the first guide wheel and the second guide wheel can ensure that the feeding and discharging of the spinning thread are placed horizontally, and will not cause excessive wear of the pressure sensor by the spinning thread.

[0009] Preferably, the gap in the middle of the first guide wheel is larger than the gap in the middle of the second guide wheel. By setting the gap in the middle of the first guide wheel larger, it is convenient for the spinning thread to pass through the gap in the middle of the first guide wheel, and by setting the gap in the middle of the second guide wheel smaller, the discharge of the spinning thread can be limited to prevent the spinning thread from swinging.

[0010] Preferably, a fixing plate is fixedly installed at the bottom end of the fixing frame, a limiting hole is opened in the middle of the fixing plate, a limiting rod is fixedly installed at the bottom of the sliding frame, the limiting rod is slidably connected to the limiting hole, and a ring for preventing the limiting rod from passing through the limiting hole is fixedly installed at the bottom of the limiting rod. When the value detected by the pressure sensor is greater than the set normal range value, it indicates that the spinning line is in a tight state, the spinning line will squeeze the pressure sensor, and then drive the sliding frame to rise, and the lifting and lowering of the sliding frame can be further positioned by setting the limiting rod.

[0011] Preferably, the limiting rod and the limiting hole fit tightly and slide, so as to achieve stable movement of the sliding frame.

[0012] Preferably, a pull spring is sleeved on the outer side of the limit rod, one end of the pull spring is fixedly connected to the upper surface of the fixed plate, and the other end of the pull spring is fixedly connected to the outer side of the limit rod. When the yarn is in a taut state and drives the sliding frame to rise, the pull spring will be driven to be in an elongated state. When the yarn is discharged normally, the pull spring pulls the limit rod to assist in pulling the sliding frame to a normal position.

[0013] Preferably, an electrostatic wire is fixedly mounted on one end of the sliding frame. When the spinning line contacts and rubs with the first guide wheel, the second guide wheel and the pressure sensor, static electricity may be generated, and the electrostatic wire can conduct the static electricity to the ground.

[0014] Compared with the prior art, the feeding mechanism for textile processing with adjustable feeding speed provided by the utility model has the following beneficial effects:

[0015] The utility model provides a feeding mechanism for textile processing with an adjustable feeding speed. When in use, the yarn is passed through a first guide wheel, a second guide wheel and below a detection end of a pressure sensor. When the yarn is fed, when the value detected by the pressure sensor is less than a set normal range value, it indicates that the yarn is in a relaxed state. The pressure sensor transmits this signal to a controller, and the controller controls the output shaft of a motor for feeding the yarn here to rotate slowly, so as to slow down the discharge of the yarn. Conversely, when the value detected by the pressure sensor is greater than a set normal range value, the output shaft of the motor for feeding the yarn here is controlled to rotate faster, so as to speed up the discharge of the yarn, thereby achieving precise adjustment of the feeding speed and improving the quality of the textile.

DETAILED DESCRIPTION

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] See also Figures 1 to 3 The utility model provides a feeding mechanism for textile processing with adjustable feeding speed, and the feeding mechanism for textile processing with adjustable feeding speed includes:

[0023] A fixing frame 1, wherein there are a plurality of fixing frames 1, and a plurality of fixing frames 1 are combined together, and the number of fixing frames 1 corresponds to the number of spinning thread feeders;

[0024] The sliding frame 2 is slidably mounted on the top of the fixed frame 1. A mounting plate 3 is fixedly mounted in the middle of the sliding frame 2. A pressure sensor 4 for detecting the tightness of the spinning thread is fixedly mounted on the lower surface of the mounting plate 3. The spinning thread is below the detection end of the pressure sensor 4. The pressure sensor 4 is electrically connected to a controller for controlling the feeding of the spinning thread. The controller is electrically connected to a motor for controlling the feeding here. Slide blocks 5 are symmetrically fixedly mounted on both sides of the sliding frame 2. Slide grooves 6 are symmetrically opened on both sides of the top of the fixed frame 1. The slide blocks 5 are slidably connected to the slide blocks 5. When the device is in use, the spinning thread is set below the detection end of the pressure sensor 4. The slack and tightness of the spinning thread are detected by the pressure sensor 4. The pressure sensor 4 transmits this signal to the controller. The controller controls the output shaft of the motor for feeding here to slow down or speed up the rotation, so as to achieve precise adjustment of the feeding speed.

[0025] See also Figures 1 to 3 , a first guide wheel 7 is rotatably mounted on one end of the sliding frame 2 through an axle pin, and a second guide wheel 8 is rotatably mounted on the other end of the sliding frame 2 through an axle pin, and the spinning line is placed in the gap between the first guide wheel 7 and the second guide wheel 8, and the first guide wheel 7 and the second guide wheel 8 are used to horizontally place the feeding and discharging of the spinning line, and the detection end of the pressure sensor 4 is slightly lower than the middle of the first guide wheel 7 and the second guide wheel 8. When placing the spinning line, passing the spinning line under the first guide wheel 7 and the second guide wheel 8 can ensure that the feeding and discharging of the spinning line are placed horizontally, and will not cause excessive wear of the pressure sensor 4 by the spinning line.

[0026] See also Figures 1 to 3 , the gap in the middle of the first guide wheel 7 is larger than the gap in the middle of the second guide wheel 8. By setting the gap in the middle of the first guide wheel 7 larger, it is convenient for the spinning thread to pass through the gap in the middle of the first guide wheel 7, and by setting the gap in the middle of the second guide wheel 8 smaller, the discharge of the spinning thread can be limited to prevent the spinning thread from swinging.

[0027] See also Figures 1 to 3 The bottom end of the fixed frame 1 is fixedly installed with a fixed plate 9, and a limit hole 10 is provided in the middle of the fixed plate 9. The bottom of the sliding frame 2 is fixedly installed with a limit rod 11, and the limit rod 11 is slidably connected with the limit hole 10. The bottom of the limit rod 11 is fixedly installed with a ring 12 for preventing the limit rod 11 from passing through the limit hole 10. When the value detected by the pressure sensor 4 is greater than the set normal range value, it indicates that the spinning line is in a tight state, and the spinning line will squeeze the pressure sensor 4, thereby driving the sliding frame 2 to rise. The limit rod 11 is set to further position the lifting and lowering of the sliding frame 2.

[0028] See also Figures 1 to 3 The limiting rod 11 slides in close contact with the limiting hole 10, so as to achieve stable movement of the sliding frame 2.

[0029] See also Figures 1 to 3 The outer side of the limit rod 11 is sleeved with a pulling spring 13, one end of the pulling spring 13 is fixedly connected to the upper surface of the fixing plate 9, and the other end of the pulling spring 13 is fixedly connected to the outer side of the limit rod 11. When the yarn is in a taut state and drives the sliding frame 2 to rise, the pulling spring 13 will be driven to be in a stretched state. When the yarn is discharged normally, the pulling spring 13 pulls the limit rod 11 to assist in pulling the sliding frame 2 to a normal position.

[0030] See also Figures 1 to 3 An electrostatic conductor 14 is fixedly mounted on one end of the sliding frame 2. When the spinning line contacts and rubs with the first guide wheel 7, the second guide wheel 8 and the pressure sensor 4, static electricity may be generated, and the electrostatic conductor 14 can conduct the static electricity to the ground.

[0031] When the device is in use, the yarn is passed through the first guide wheel 7, the second guide wheel 8 and the bottom of the detection end of the pressure sensor 4. When the yarn is fed, since the yarn will squeeze the pressure sensor 4, the tension of the yarn will be detected by the pressure sensor 4. The pressure sensor 4 is set to detect the normal pressure value range of the yarn tension. When the value detected by the pressure sensor 4 is less than the set normal range value, it indicates that the yarn is in a relaxed state. The pressure sensor 4 transmits this signal to the controller, and the controller controls the output shaft of the motor for feeding here to slow down the rotation, so as to slow down the discharge of the yarn. When the value detected by the pressure sensor 4 is greater than the set normal range value, it indicates that the yarn is in a tight state. The pressure sensor 4 transmits this signal to the controller, and the controller controls the output shaft of the motor for feeding here to speed up the rotation, so as to speed up the discharge of the yarn, thereby realizing precise adjustment of the feeding speed.
