Description

Technical Field

[0001] This application relates to the field of fabric shaping technology, and in particular to the fabric feeding mechanism of a shaping machine. Background Technology

[0002] The fabric feeding mechanism of the fabric setting machine is a key component used to transport the fabric to be set into the machine during the fabric setting process. Its main function is to ensure that the fabric is transported flat and wrinkle-free when it enters the setting machine, thereby improving the setting quality of the fabric.

[0003] Currently, the fabric loading mechanism of a fabric setting machine mainly includes a frame, a conveyor for carrying and transporting the fabric (including conveyor rollers and a power unit for driving the conveyor rollers and conveyor belt), and multiple pressing rollers installed on both sides of the frame to press the fabric and prevent wrinkles from forming during transport. Through the coordinated work of each component, the fabric loading mechanism can prevent the fabric from folding or wrinkling during transport, while saving manpower and improving the setting quality and production efficiency of the fabric. However, during the continuous transport of the fabric, the pressing rollers will continuously rub against the fabric to generate static electricity. Static electricity will cause impurities such as loose fibers and loose threads on the fabric to be attracted and wrapped around the pressing rollers, causing jamming, affecting the normal operation of the pressing rollers and the transport of the fabric, and reducing the quality of the fabric. Utility Model Content

[0004] In order to improve the stability of the press roller operation and improve the quality of the fabric, this application provides a fabric feeding mechanism for a setting machine.

[0005] The fabric feeding mechanism of the setting machine provided in this application adopts the following technical solution:

[0006] The fabric feeding mechanism of the setting machine includes:

[0007] A frame, on which a conveyor for conveying fabric and multiple pressing rollers are provided, the multiple pressing rollers being located on both sides of the fabric movement direction;

[0008] The cleaning mechanism, located between the frame and the pressing roller, includes a dirt removal component and a stripping component. The dirt removal component is used to clean the impurities adsorbed on the pressing roller; the stripping component is used to strip and collect the impurities cleaned by the dirt removal component.

[0009] By adopting the above technical solution, when the fabric is fed into the fabric setting machine through the fabric feeding mechanism, the fabric moves smoothly forward through the conveyor on the conveyor. At the same time, multiple pressing rollers on both sides of the fabric movement direction prevent wrinkles or folds from forming during the conveying process, ensuring that the fabric remains flat before entering the setting machine. During the rolling friction between the fabric and the pressing rollers, a certain amount of static electricity is generated, causing impurities such as lint and loose threads on the fabric to be attracted to the pressing rollers. When impurities appear on the pressing rollers, the cleaning mechanism is activated. The impurity removal component in the cleaning mechanism is used to remove the impurities attracted to the surface of the pressing rollers, while the stripping component peels off and collects the impurities removed by the impurity removal component. The impurity removal component and the stripping component work together to periodically clean the impurities on the pressing rollers, avoiding the accumulation of impurities such as lint and loose threads that could cause the pressing rollers to jam, ensuring the normal operation of the pressing rollers, improving the stability and reliability of the fabric feeding mechanism, reducing the impact of impurities on the pressing rollers on the fabric, and improving the setting quality of the fabric.

[0010] Optionally, the impurity removal component includes:

[0011] The negative pressure fan is located on one side of the pressing roller;

[0012] Negative pressure piping is installed between the negative pressure fan and the pressing roller;

[0013] The filter screen is installed inside the negative pressure pipe and on the side close to the negative pressure fan.

[0014] By adopting the above technical solution, when removing impurities adsorbed on the pressing roller using the impurity removal component, the negative pressure fan is first started. The suction force generated by the negative pressure fan is transmitted to the vicinity of the pressing roller through the negative pressure pipeline. Under the action of negative pressure suction, impurities such as lint and lint on the surface of the pressing roller are sucked into the negative pressure pipeline and filtered through the filter screen inside the negative pressure pipeline. In this way, cleaning the surface of the pressing roller by the suction force generated by negative pressure can not only efficiently remove light impurities such as lint and lint adhering to the pressing roller, but also will not interfere with the normal operation of the pressing roller. At the same time, the pressing roller does not need to be stopped during cleaning, thus improving production efficiency.

[0015] Optionally, the filter screen is made of a conductive material, and the filter screen is connected to the outside by conductive wires.

[0016] By adopting the above technical solution, the conductive material filter can safely conduct the static charge on the impurities to the ground through the external conductive wire, thereby effectively eliminating static electricity, avoiding static accumulation, and reducing safety hazards.

[0017] Optionally, the stripping component includes:

[0018] A stripping plate is installed inside a negative pressure pipeline;

[0019] A brush is fixed to one side of the stripping plate, and the brush abuts against the filter plate;

[0020] The lead screw is rotatably connected to the negative pressure pipeline and is threadedly connected to the stripping plate;

[0021] The guide rod is fixed to the negative pressure pipe and is slidably connected to the stripping plate;

[0022] The drive motor is located at one end of the lead screw.

[0023] Optionally, the stripping component further includes:

[0024] An anemometer, installed inside a negative pressure duct, is used to detect the airflow speed within the duct and send out a detection signal.

[0025] The start controller, connected to the wind speed sensor and drive motor, is used to receive detection signals to determine the airflow speed in the negative pressure pipe. When the airflow speed is less than the preset speed, the drive motor starts to move the brush.

[0026] By adopting the above technical solution, when the negative pressure fan starts, the wind speed sensor continuously monitors the airflow speed in the negative pressure pipeline. When the detected airflow speed is lower than the preset speed, it indicates that the filter screen may be clogged due to the accumulation of impurities, affecting the normal passage of airflow. At this time, the start controller receives the detection signal from the wind speed sensor, determines that the filter screen needs to be cleaned, and then sends a start signal to the drive motor. The drive motor then starts and drives the lead screw to rotate. Under the drive of the lead screw, the peeling plate slides along the guide rod. As the peeling plate moves, the brush cleans the filter screen, brushing off the impurities attached to the filter screen, thereby ensuring the permeability of the mesh holes on the filter screen. The peeling component can automatically clean the filter screen, reducing manual intervention, and by regularly cleaning the filter screen, the airflow speed in the negative pressure pipeline is ensured, improving the cleaning effect on the impurities on the pressure roller.

[0027] Optionally, a collection box is provided below the filter screen, and a connecting pipe is provided between the collection box and the negative pressure pipe. A door panel for opening or closing the connecting pipe is hinged to the connecting pipe, and an opening and closing motor is provided at one end of the hinge shaft of the door panel.

[0028] By adopting the above technical solution, the impurities filtered by the filter screen will enter and be temporarily stored in the connecting pipe. The staff can periodically start the opening and closing motor to open the door panel, allowing the impurities above the door panel to enter the collection box. After the impurities above the door panel are cleaned, the opening and closing motor is started in reverse to close the door panel and restore the closed state of the connecting pipe.

[0029] Optionally, the opening and closing motor is a self-locking holding brake motor.

[0030] By adopting the above technical solution, when the power is off or the motor stops running, the self-locking brake motor will lock the motor shaft to prevent the door panel from flipping down and opening due to gravity or external force, thus ensuring the stable operation of the cleaning mechanism. In addition, when the self-locking brake motor is in the brake state, the motor does not need to be continuously powered to keep the door panel fixed, reducing energy consumption.

[0031] Optionally, a windproof cover is fixed to the side of the negative pressure pipe near the pressing wheel, and a scraper is fixed to the windproof cover, the scraper abutting against the pressing wheel.

[0032] By adopting the above technical solution, the windproof cover is used to prevent the negative pressure suction from spreading, so that the negative pressure suction only treats the surface of the pressing wheel, reducing the energy consumption of the negative pressure fan. At the same time, the scraper helps to remove impurities attached to the surface of the pressing wheel, improving the cleaning effect of the impurity removal component.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. By using the impurity removal component and the stripping component together, impurities on the pressing roller can be cleaned regularly, avoiding the accumulation of impurities such as lint and thread that could cause the pressing roller to jam. This ensures the normal operation of the pressing roller, improves the stability and reliability of the fabric feeding mechanism, and reduces the impact of impurities on the pressing roller on the fabric, thereby improving the fabric's shaping quality.

[0035] 2. The impurity removal component cleans the surface of the pressing roller using suction generated by negative pressure. This not only efficiently removes light impurities such as lint and loose threads adhering to the pressing roller, but also does not interfere with the normal operation of the pressing roller. Furthermore, the pressing roller does not require machine shutdown during cleaning, thus improving production efficiency. In addition, the conductive filter screen can safely conduct the static charge on the impurities to the ground through external conductive wires, thereby effectively eliminating static electricity, preventing static accumulation, and reducing safety hazards.

[0036] 3. The stripping component can automatically clean the filter screen, reducing manual intervention. Regularly cleaning the filter screen ensures the airflow speed in the negative pressure pipeline, improving the cleaning effect on impurities on the pressure roller. Attached Figure Description

[0041] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0042] This application discloses a fabric feeding mechanism for a setting machine. (Refer to...) Figure 1 and Figure 2 The fabric feeding mechanism of the setting machine includes a frame 1, on which a conveyor for conveying fabric 2 and multiple pressing rollers 3 are mounted. The multiple pressing rollers 3 are located on both sides of the fabric 2 in the direction of movement. A cleaning mechanism 4 is provided between the frame 1 and the pressing rollers 3. The cleaning mechanism 4 includes a dirt removal component 41 and a stripping component 42. The dirt removal component 41 is used to clean the impurities adsorbed on the pressing rollers 3. The stripping component 42 is used to strip and collect the impurities cleaned by the dirt removal component 41.

[0043] When fabric 2 is fed into the fabric setting machine via the feeding mechanism, it moves smoothly forward via the conveyor. Simultaneously, multiple pressing rollers 3 on both sides of the fabric 2's direction of movement prevent wrinkles or folds during transport, ensuring the fabric 2 remains flat before entering the setting machine. During the rolling friction between the fabric 2 and the pressing rollers 3, static electricity is generated, causing impurities such as lint and loose threads on the fabric 2 to adhere to the pressing rollers 3. When impurities appear on the pressing rollers 3, the cleaning mechanism 4 is activated. The impurity removal component 41 in the cleaning mechanism 4 removes the impurities adsorbed on the surface of the pressing rollers 3, while the peeling component 42 peels off and collects the impurities removed by the impurity removal component 41.

[0044] Reference Figure 2 and Figure 3The impurity removal component 41 includes a negative pressure fan 411 disposed on one side of the pressing roller 3, and a negative pressure pipe 412 disposed between the negative pressure fan 411 and the pressing roller 3. A filter screen 413 is disposed inside the negative pressure pipe 412, located on the side of the negative pressure pipe 412 near the negative pressure fan 411. The filter screen 413 is made of a conductive metal material, but other conductive materials can also be used, and the filter screen 413 is connected to a conductive wire to the outside. A windproof cover 414 is fixedly disposed on the side of the negative pressure pipe 412 near the pressing roller 3, and a scraper 415 is fixedly disposed on the windproof cover 414. The scraper 415 abuts against the outer surface of the pressing roller 3. The windproof cover 414 is used to prevent the negative pressure suction from spreading, so that the negative pressure suction only treats the surface of the pressing roller 3, reducing the energy consumption of the negative pressure fan 411. At the same time, the scraper 415 facilitates the removal of impurities attached to the surface of the pressing roller 3.

[0045] When the impurities adsorbed on the pressing roller 3 are removed by the impurity removal component 41, the negative pressure fan 411 is first started. The suction force generated by the negative pressure fan 411 is transmitted to the vicinity of the pressing roller 3 through the negative pressure pipe 412. Under the action of negative pressure suction, impurities such as lint and lint on the surface of the pressing roller 3 are sucked into the negative pressure pipe 412 and filtered through the filter screen 413 inside the negative pressure pipe 412. The filter screen 413 can safely conduct the static charge on the impurities to the ground through the external conductive wire, thereby effectively eliminating static electricity, avoiding static electricity accumulation, and reducing safety hazards. In this way, cleaning the surface of the pressing roller 3 by the suction force generated by negative pressure can not only efficiently remove light impurities such as lint and lint adhering to the pressing roller 3, but also will not interfere with the normal operation of the pressing roller 3. At the same time, the pressing roller 3 does not need to be stopped during cleaning, which improves production efficiency.

[0046] Reference Figure 2 and Figure 3 The peeling assembly 42 includes a peeling plate 421 disposed within a negative pressure pipe 412. A brush 422 is fixedly mounted on one side of the peeling plate 421, and the brush 422 abuts against the filter plate. A lead screw 423 is rotatably connected to the negative pressure pipe 412, and the lead screw 423 is threadedly connected to the peeling plate 421. A guide rod 424 is fixedly mounted on the negative pressure pipe 412, and the guide rod 424 passes through the peeling plate 421 and is slidably connected to the peeling plate 421. A drive motor 425 is disposed at one end of the lead screw. The peeling assembly 42 also includes a wind speed sensor and a start controller. The wind speed sensor is disposed within the negative pressure pipe 412 and is used to detect the airflow speed within the negative pressure pipe 412 and send a detection signal. The start controller is connected to the wind speed sensor and the drive motor 425 and is used to receive the detection signal to determine the airflow speed within the negative pressure pipe 412. When the airflow speed is less than a preset speed, the drive motor 425 starts to move the brush 422.

[0047] When the negative pressure fan 411 starts, the wind speed sensor continuously monitors the airflow speed in the negative pressure pipe 412. When the detected airflow speed is lower than the preset speed, it indicates that the filter screen 413 may be clogged due to the accumulation of impurities, affecting the normal passage of airflow. At this time, the start controller receives the detection signal from the wind speed sensor and determines that the filter screen 413 needs to be cleaned. Then, the start controller sends a start signal to the drive motor 425, and the drive motor 425 starts and drives the lead screw 423 to rotate. Under the drive of the lead screw 423, the peeling plate 421 slides along the guide rod 424. As the peeling plate 421 moves, the brush 422 cleans the filter screen 413, brushing off the impurities attached to the filter screen 413, thereby ensuring the permeability of the mesh holes of the filter screen 413. The peeling component 42 can automatically clean the filter screen 413, reducing manual intervention, and by regularly cleaning the filter screen 413, it ensures the airflow speed in the negative pressure pipe 412 and improves the cleaning effect on the impurities on the pressure roller 3.

[0048] Reference Figure 2 and Figure 3 The stripping assembly 42 also includes a collection box 426 disposed below the filter screen 413. A hinged door 4261 is attached to the collection box 426, and a latch 4262 is provided between the door 4261 and the collection box 426. A connecting pipe 427 is provided between the collection box 426 and the negative pressure pipe 412. A door plate 428 for opening or closing the connecting pipe 427 is hinged to the connecting pipe 427. An opening / closing motor 429 is provided at one end of the hinge shaft of the door plate 428, and the opening / closing motor 429 is a self-locking brake motor.

[0049] Impurities filtered by filter 413 enter and are temporarily stored in the connecting pipe 427. Operators can periodically activate the opening and closing motor 429 to open the door panel 428, allowing impurities above the door panel 428 to enter the collection box 426. Once the impurities above the door panel 428 have been cleaned, the opening and closing motor 429 reverses direction, closing the door panel 428 and restoring the connecting pipe 427 to its closed state. The self-locking brake motor, when powered off or stopped, has a brake system that locks the motor shaft, preventing the door panel 428 from flipping open due to gravity or external force, ensuring stable operation of the cleaning mechanism 4. Furthermore, in the braked state, the self-locking brake motor does not require continuous power to maintain the door panel 428 in a fixed position, reducing energy consumption.

[0050] The implementation principle of the fabric feeding mechanism of a setting machine according to an embodiment of this application is as follows: When the fabric 2 is fed into the setting machine through the fabric feeding mechanism, the fabric 2 moves smoothly forward through the conveying device on the conveyor. At the same time, multiple pressing rollers 3 on both sides of the fabric 2 in the direction of movement prevent wrinkles or folds from forming during the conveying process, ensuring that the fabric 2 remains flat before entering the setting machine. During the rolling friction between the fabric 2 and the pressing rollers 3, a certain amount of static electricity is generated, causing impurities such as loose fibers and threads on the fabric 2 to be adsorbed onto the pressing rollers 3. When impurities appear on the pressing rollers 3, the cleaning mechanism 4 is activated. The impurity removal component 41 in the cleaning mechanism 4 is used to clean the impurities adsorbed on the surface of the pressing rollers 3, while the peeling component 42 peels off and collects the impurities cleaned by the impurity removal component 41. The impurity removal component 41 and the stripping component 42 work together to periodically clean impurities on the pressing roller 3, preventing the accumulation of impurities such as lint and thread ends from causing the pressing roller 3 to jam, ensuring the normal operation of the pressing roller 3, improving the stability and reliability of the fabric feeding mechanism, and reducing the impact of impurities on the pressing roller 3 on the fabric 2, thereby improving the shaping quality of the fabric 2.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
