Description

Technical Field

[0001] This application relates to the field of spinning and processing technology, and more specifically, to a novel cotton yarn feeding device for cotton yarn processing. Background Technology

[0002] In the cotton yarn processing process, the feeding device is a key piece of equipment that connects the unwinding of cotton yarn with subsequent processing steps (such as spinning and winding), and its performance directly affects the quality of cotton yarn processing and production efficiency.

[0003] The prior art publication CN118547404A discloses a novel cotton yarn feeding device for cotton yarn processing. This device, through the installation of a discharge mechanism, allows a pusher block to move the cotton yarn, preventing it from remaining in the feeding plate due to static electricity or friction, thus avoiding manual removal and impacting feeding efficiency. It saves manpower and is highly practical. Furthermore, an external protective mechanism is installed, with protective plates one and two blocking and protecting both sides of the discharge port, preventing the cotton yarn from scattering and falling outside the processing equipment, thus ensuring feeding accuracy and normal operation. The device has a simple structure and is highly practical.

[0004] Although the existing technical solutions mentioned above can achieve the relevant beneficial effects through the existing technical structure, they still have the following defects: First, the pusher block reset relies on manual pulling of the pull ring, which requires a dedicated person to operate it. This not only increases the labor intensity, but also causes the pushing frequency to be limited by the manual reaction speed, making it unsuitable for high-speed production lines. Second, the pusher block adopts a planar rigid structure, which is prone to accumulation and jamming due to uneven force on the material during the pushing process. In addition, the pushing trajectory is a uniform straight line, and the material is prone to residue when it collides with the discharge port, resulting in poor discharge effect and seriously affecting production efficiency and material utilization.

[0005] While existing automated feeding technologies include cylinder-driven or rack and pinion transmission solutions, cylinder transmission relies on an air source and has low stroke adjustment precision, while rack and pinion transmission is prone to feeding lag due to tooth backlash. Neither can simultaneously address the dual requirements of "automatic reset" and "optimized material discharge effect." Therefore, a mechanical transmission structure that combines high automation, low material residue rate, and structural stability is urgently needed to achieve automated feeding and discharging. This is of great significance.

[0006] In view of this, a novel cotton yarn feeding device for cotton yarn processing is proposed. Summary of the Invention

[0007] To achieve the above objectives, the present invention provides the following technical solution: a novel cotton yarn feeding device for cotton yarn processing, comprising:

[0008] Feeding plate;

[0009] A discharge mechanism, mounted on the feeding plate, is used to realize unidirectional conveying of cotton material. The discharge mechanism includes:

[0010] A tilting component, located outside the feeding plate, is used to adjust the tilt angle of the feeding plate;

[0011] A conveying assembly is disposed between the turning assembly and the feeding plate for driving the cotton material conveying. The conveying assembly includes a drive roller, a transmission component, a guide frame, and an electrostatic conveyor belt.

The two sprocket structures are symmetrically fixedly connected between the two drive rollers. The drive motor is connected to one of the drive rollers through a coupling and fixed to one side of the flipping assembly.

[0014] The guide frame is disposed inside the feed plate and is used to guide the electrostatic conveyor belt to maintain stable conveying.

[0015] A sensor control system is installed between the discharge mechanism and the feeding plate to monitor the material status in real time and dynamically adjust the conveying process.

[0016] As an optional solution to the technical solution in this application, a U-shaped movable groove is provided on one side of the feeding plate, and an electrostatic rubber baffle is fixedly provided in the middle of the U-shaped movable groove.

[0017] As an optional solution to the technical solution in this application, the tilting assembly includes a carrier plate connecting seat, an electric lifting rod, and a limiting truss.

[0018] One end of the carrier plate connecting seat is hinged to the limiting truss, and the other end is hinged to the limiting truss through the electric lifting rod;

[0019] The limiting truss is fixedly installed on the outside of the feeding plate and is rotatably connected to the conveying assembly.

[0020] As an optional solution to the technical solution in this application, the device further includes a cleaning structure, which includes an exhaust fan, an air guide column cover, an electrostatic cleaning brush, and a cleaning motor.

[0021] The exhaust fan is fixed to one side of the limiting truss via a connecting seat, and its exhaust end is connected to the air guide column cover.

[0022] The air guide column cover is fixed to the middle of the limiting truss and is sleeved on the outside of the cleaning motor;

[0023] The cleaning motor is fixed inside the air guide column cover by a motor mount, and its output end is connected to the electrostatic cleaning brush.

[0024] As an optional solution to the technical solution in this application, the guide frame includes a ring frame and a positioning frame;

[0025] The ring frame is fixed inside the feeding plate and its outer surface is coated with an electrostatic isolating agent.

[0026] The two positioning frames are symmetrically slidably disposed within the annular frame and are fixedly connected to the electrostatic conveyor belt.

[0027] As an optional solution to the technical solution in this application, the positioning frame includes an annular plastic ring, and multiple electrostatic scrapers are fixed between the plastic ring and the electrostatic conveyor belt at equal intervals.

[0028] As an optional solution to the technical solution in this application, the electrostatic scraper has a right-angled trapezoidal structure.

[0029] As an optional solution to the technical solution in this application, the electrostatic conveyor belt has a hollow internal structure and multiple folded compressed air plates are fixed at equal intervals. Several air holes are opened on one side of each folded compressed air plate, and the folded compressed air plates are connected to each other by flexible hoses.

[0030] As an optional solution to the technical solution in this application, the folded compressed air plate is an elastic air cylinder structure composed of a folded compressed rubber cylinder and multiple spring components.

[0031] As an optional solution to the technical solution in this application, the sensing and control system includes a first sensor, a second sensor, and a controller;

[0032] The first sensor is located at the feed inlet of the feeding plate and is used to detect whether the material is in place;

[0033] The second sensor is located at the discharge port of the tilting assembly and is used to detect whether the material has been completely discharged;

[0034] The controller is electrically connected to the first sensor, the second sensor, and the drive motor, respectively, and is used to control the operation of the drive motor according to the sensor signals.

[0035] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0036] 1. This application utilizes a tilting component to adjust the tilt angle of the feeding plate according to processing requirements, creating suitable gravity-assisted conditions for cotton material conveying. Next, the drive motor starts, driving one of the drive rollers to rotate via a coupling. The sprocket structure on this drive roller engages with the sprocket structure on the other drive roller via a chain, achieving synchronous rotation of the two drive rollers. The rotation of the two drive rollers drives the electrostatic conveyor belt mounted on them. Guided by a guide frame, the electrostatic conveyor belt maintains a stable conveying trajectory, unidirectionally conveying the cotton material on the feeding plate to the discharge mechanism. During this process, the sensor control system monitors the material status in real time, such as the cotton material accumulation height and conveying speed, and dynamically adjusts the speed of the drive motor according to a preset program or manual instructions. Because the drive motor has stepless speed regulation, combined with the synchronous transmission characteristics of the sprocket structure, precise control of the conveying speed can be achieved, meeting the feeding speed requirements of different processing steps. By utilizing a sprocket structure in conjunction with a drive motor, precise control of the conveying speed is achieved, flexibly adapting to the varying feeding speed requirements of different processing steps, thereby improving processing efficiency and product quality. The guide frame ensures stable operation of the electrostatic conveyor belt, while the tilting component adjusts the inclination angle of the feeding plate. Together with the conveying components, this ensures stable unidirectional conveying of cotton materials, reducing problems such as material jamming and accumulation caused by unstable conveying. The sensor control system monitors and dynamically adjusts the conveying process in real time, achieving intelligent feeding, reducing manual intervention costs, and improving the reliability and stability of the feeding device.

[0037] 2. This application employs a multi-layered composite structure design in the discharge mechanism, particularly the electrostatic conveyor belt combined with guide frames, electrostatic scrapers, and folded compressed air plates, to form a highly efficient and low-damage material conveying system. The electrostatic conveyor belt has a hollow structure and folded compressed air plates, which generate pulsed airflow during operation, keeping the cotton material in a suspended state during conveying. This significantly reduces direct friction with the conveyor belt surface, thereby significantly reducing problems such as cotton yarn fuzzing and breakage, and improving the processing quality of the cotton yarn.

[0038] 3. This application further enhances the overall performance and environmental adaptability of the equipment by integrating a cleaning structure and a tilting component. The cleaning structure, through the cooperation of an exhaust fan, air guide column cover, and electrostatic cleaning brush, automatically activates after each conveying cycle to thoroughly clean the surface of the electrostatic conveyor belt, preventing fiber residue and dust diffusion, ensuring a clean and safe production environment, and extending the equipment's service life. The tilting component, through an electric lifting rod and carrier plate connecting seat, allows for stepless adjustment of the feed plate's tilt angle. The optimal feeding angle can be flexibly set according to the properties of the cotton material, further improving conveying efficiency and adaptability. Attached Figure Description

Detailed Implementation

[0053] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0054] Reference Figures 1-5 A novel cotton yarn feeding device for cotton yarn processing includes:

[0055] Feeding plate 100;

[0056] The discharge mechanism 200, mounted on the feeding plate 100, is used to realize unidirectional conveying of cotton material. The discharge mechanism 200 includes:

[0057] The tilting component 210 is located outside the feeding plate 100 and is used to adjust the tilt angle of the feeding plate 100.

[0058] The conveying assembly 220 is located between the turning assembly 210 and the feeding plate 100 and is used to drive the cotton material conveying. The conveying assembly 220 includes a drive roller 230, a transmission component 240, a guide frame 250 and an electrostatic conveyor belt 260.

[0059] The two drive rollers 230 are arranged symmetrically and are rotatably connected inside the flipping assembly 210;

[0060] The transmission component 240 is used to drive the drive roller 230 to achieve stable transmission. It includes a sprocket structure 241 and a drive motor 242. The two sprocket structures 241 are symmetrically fixed between the two drive rollers 230. The drive motor 242 is connected to one of the drive rollers 230 through a coupling and is fixed to one side of the flipping component 210.

[0061] The guide frame 250 is located inside the feed plate 100 and is used to guide the electrostatic conveyor belt 260 to maintain stable conveying.

[0062] The sensor control system 300 is located between the discharge mechanism 200 and the feeding plate 100, and is used to monitor the material status in real time and dynamically adjust the conveying process.

[0063] This novel cotton yarn feeding device for cotton yarn processing adjusts the tilt angle of the feeding plate 100 according to processing requirements via the tilting component 210, creating suitable gravity-assisted conditions for cotton material conveying. Next, the drive motor 242 starts, driving one of the drive rollers 230 to rotate via a coupling. The sprocket structure 241 on this drive roller 230 engages with the sprocket structure 241 on the other drive roller 230 via a chain, achieving synchronous rotation of the two drive rollers 230. The rotation of the two drive rollers 230 drives the electrostatic conveyor belt 260 mounted on them to rotate. Guided by the guide frame 250, the electrostatic conveyor belt 260 maintains a stable conveying trajectory, unidirectionally conveying the cotton material on the feeding plate 100 to the discharge mechanism 200. During this process, the sensor control system 300 monitors the material status in real time, such as the cotton material accumulation height and conveying speed, and dynamically adjusts the speed of the drive motor 242 according to a preset program or manual instructions. Since the drive motor 242 has a stepless speed regulation function, combined with the synchronous transmission characteristics of the sprocket structure 241, the conveying speed can be precisely controlled to meet the feeding speed requirements of different processing steps.

[0064] By utilizing the sprocket structure 241 in conjunction with the drive motor 242, precise control of the conveying speed is achieved, which can flexibly adapt to the different requirements of feeding speed for different processing steps, thereby improving processing efficiency and product quality. The guide frame 250 ensures the stable operation of the electrostatic conveyor belt 260, and the tilting component 210 can adjust the tilt angle of the feeding plate 100. Together with the conveying component 220, it ensures stable unidirectional conveying of cotton material and reduces problems such as material jamming and accumulation caused by unstable conveying. The sensor control system 300 monitors and dynamically adjusts the conveying process in real time, realizing intelligent feeding, reducing manual intervention costs, and improving the reliability and stability of the feeding device.

[0065] Reference Figure 6 and Figure 7 A U-shaped movable groove is provided on one side of the feeding plate 100, and an electrostatic rubber baffle 110 is fixedly installed in the middle of the U-shaped movable groove.

[0066] This novel cotton yarn feeding device for cotton yarn processing allows cotton yarn to enter the device through the inlet and first contact the feeding plate 100. A U-shaped movable trough on one side of the feeding plate 100 provides a track for the conveying assembly 220 to remove residual cotton yarn. As the conveying assembly 220 moves within the U-shaped movable trough, a gap is created between it and the trough body. At this time, the electrostatic rubber baffle 110 fixedly installed in the middle of the U-shaped movable trough begins to function, tightly fitting the trough and effectively preventing the cotton yarn from scattering from the side, ensuring stable conveying of the cotton yarn along the predetermined track until it enters the next processing stage.

[0067] By utilizing the synergistic cooperation between the feeding plate 100 and the electrostatic rubber baffle 110, the conductive properties of the electrostatic rubber baffle 110 are used to eliminate the static electricity generated by the friction between the cotton material and the wall of the U-shaped movable groove, ensuring the stability of the processing environment and the quality of the cotton yarn; at the same time, its elastic edge structure prevents the cotton material from scattering, significantly reducing material loss and effectively improving the production efficiency and economic benefits of cotton yarn processing.

[0068] Reference Figure 3 and Figure 4 The tilting assembly 210 includes a carrier plate connecting seat 211, an electric lifting rod 212, and a limiting truss 213;

[0069] One end of the carrier plate connecting seat 211 is hinged to the limiting truss 213, and the other end is hinged to the limiting truss 213 via the electric lifting rod 212;

[0070] The limiting truss 213 is fixedly installed on the outside of the feeding plate 100 and is rotatably connected to the conveying assembly 220.

[0071] This novel cotton yarn feeding device for cotton yarn processing is fixedly installed on the outside of the feeding plate 100 via a limiting truss 213 and is rotatably connected to the conveying component 220, providing a stable support foundation for the entire flipping component 210.

[0072] When the tilt angle of the feeding plate 100 needs to be adjusted, the electric lifting rod 212 begins to extend and retract. During the extension and retraction of the electric lifting rod 212, it drives the carrier plate connecting seat 211 to move. Since one end of the carrier plate connecting seat 211 is hinged to the limiting truss 213, and the other end is also hinged to the limiting truss 213 through the electric lifting rod 212, the tilt angle of the feeding plate 100 is changed.

[0073] By utilizing the combination of the carrier plate connecting seat 211, electric lifting rod 212, and limiting truss 213 in the tilting component 210, the tilt angle of the feeding plate 100 can be flexibly adjusted. The optimal feeding angle can be precisely set according to the different characteristics of lightweight and heavy cotton yarn, thereby improving the efficiency and quality of cotton yarn processing.

[0074] Reference Figure 1 and Figure 4 The device also includes a cleaning structure 400, which includes an exhaust fan 410, an air guide column cover 420, an electrostatic cleaning brush 430, and a cleaning motor 440.

[0075] The exhaust fan 410 is fixed to one side of the limiting truss 213 via a connecting seat, and its exhaust end is connected to the air guide column cover 420.

[0076] The air guide column cover 420 is fixed to the middle of the limiting truss 213 and sleeved on the outside of the cleaning motor 440;

[0077] The cleaning motor 440 is fixed inside the air guide column cover 420 by a motor mount, and its output end is connected to the electrostatic cleaning brush 430.

[0078] This novel cotton yarn feeding device for cotton yarn processing is started by energizing a cleaning motor 440, which is fixed inside the air guide column cover 420 via a motor mount. The output end drives the electrostatic cleaning brush 430 to start rotating. The nylon bristles of the electrostatic cleaning brush 430 can penetrate deep into the surface texture of the electrostatic conveyor belt 260, preparing for the removal of residual fibers.

[0079] As the electrostatic cleaning brush 430 continues to rotate, the nylon bristles thoroughly clean the surface of the electrostatic conveyor belt 260, removing residual fibers from the surface of the electrostatic conveyor belt 260.

[0080] While the cleaning motor 440 drives the electrostatic cleaning brush 430, the exhaust fan 410 starts. The exhaust fan 410 is fixed to one side of the limiting truss 213 via a connecting seat, and its exhaust end is connected to the air guide column cover 420, generating negative pressure airflow during operation. This negative pressure airflow forms an annular air curtain through the air guide column cover 420, which can completely enclose and collect the dust generated by the electrostatic cleaning brush 430, preventing dust from spreading and causing secondary pollution.

[0081] This cleaning structure 400, through the close cooperation of its components, forms an integrated "sweeping-dust removal" workflow. Its beneficial effects include: utilizing the fine cleaning capability of the electrostatic cleaning brush 430 to effectively remove residual fibers from the surface of the electrostatic conveyor belt 260; simultaneously, the annular air curtain formed by the exhaust fan 410 and the air guide column cover 420 completely collects the dust generated during cleaning, preventing secondary pollution, ensuring a clean cotton yarn processing environment, effectively improving the quality and efficiency of cotton yarn processing, and reducing equipment malfunctions and product defects caused by fiber residue and dust.

[0082] Reference Figures 8-10 The guide frame 250 includes a ring frame 251 and a positioning frame 252;

[0083] The ring frame 251 is fixed inside the feed plate 100, and its outer surface is coated with an electrostatic isolating agent;

[0084] Two positioning frames 252 are symmetrically slidably disposed within the ring frame 251 and are fixedly connected to the electrostatic conveyor belt 260;

[0085] The positioning frame 252 includes an annular plastic ring 253. Multiple electrostatic scrapers 254 are fixed at equal intervals between the plastic ring 253 and the electrostatic conveyor belt 260. The electrostatic scrapers 254 have a right-angled trapezoidal structure.

[0086] This novel cotton yarn feeding device for cotton yarn processing is fixed inside the feeding plate 100 by a ring frame 251. The nano-level electrostatic isolating agent coated on its surface forms a high-resistance coating, which blocks the electrostatic conduction path and prevents the cotton material from deviating from the track due to electrostatic adsorption.

[0087] Two symmetrically arranged positioning frames 252 slide within the ring frame 251 and are rigidly connected to the electrostatic conveyor belt 260, allowing their positions to be adjusted according to feeding requirements. The plastic ring 253 of the positioning frame 252 works in conjunction with the electrostatic conveyor belt 260 through equally spaced electrostatic scrapers 254. The electrostatic scrapers 254 have a right-angled trapezoidal structure. During operation, the electrostatic conveyor belt 260 drives the positioning frame 252 to move, and the hypotenuse of the right-angled trapezoidal electrostatic scrapers 254 generates a directional thrust on the cotton material, using the principle of mechanical guidance to push the cotton material along a preset trajectory, counteracting the electrostatic offset caused by fiber friction.

[0088] This structure improves the positioning accuracy of cotton material through a triple mechanism of "electrostatic blocking, dynamic positioning, and mechanical guidance," effectively reducing deviation caused by electrostatic adsorption, ensuring the stability and accuracy of the feeding process, and improving cotton yarn processing efficiency and finished product quality.

[0089] Reference Figure 11 and Figure 12 The electrostatic conveyor belt 260 has a hollow internal structure and multiple folded compressed air plates 261 are fixed at equal intervals. Several air holes are opened on one side of each folded compressed air plate 261. The folded compressed air plates 261 are connected by hoses. The folded compressed air plate 261 is an elastic air cylinder structure composed of a folded compressed rubber cylinder and multiple spring components.

[0090] This novel cotton yarn feeding device for cotton yarn processing involves the movement of the folded compressed air plate 261 in the internal hollow structure when the electrostatic conveyor belt 260 starts running.

[0091] Since the folded compressed air plate 261 is an elastic air cylinder structure composed of a folded compressed rubber cylinder and multiple spring components, it undergoes elastic expansion and contraction under the force of the electrostatic conveyor belt 260 running.

[0092] Each of the folded compressed air plates 261 is connected by a hose, and the elastic expansion and contraction process generates pulsed airflow.

[0093] The pulsed airflow is ejected from the air hole opened on one side of the folded compressed air plate 261, forming an airflow barrier between the cotton material and the surface of the electrostatic conveyor belt 260, so that the cotton material is suspended at a distance from the surface of the electrostatic conveyor belt 260.

[0094] Under this workflow, the cotton yarn feeding device has significant benefits: by cooperating with the folded compressed air plate 261 and the electrostatic conveyor belt 260, the cotton material is suspended and conveyed by utilizing the airflow barrier. While ensuring the conveying power, the direct friction between the cotton material and the electrostatic conveyor belt 260 is greatly reduced, which effectively reduces the cotton yarn fuzzing rate and improves the quality and efficiency of cotton yarn processing.

[0095] Reference Figure 2 and Figure 13 The sensing control system 300 includes a first sensor 310, a second sensor 320, and a controller 330;

[0096] The first sensor 310 is located at the feed inlet of the feed plate 100 and is used to detect whether the material is in place;

[0097] The second sensor 320 is located at the discharge port of the tilting assembly 210 and is used to detect whether the material has been completely discharged.

[0098] The controller 330 is electrically connected to the first sensor 310, the second sensor 320 and the drive motor 242 respectively, and is used to control the operation of the drive motor 242 according to the sensor signals.

[0099] This novel cotton yarn feeding device for cotton yarn processing uses a first sensor 310, based on infrared beam detection, to accurately identify whether the cotton material is in place by conveying the material to the feed inlet of the feed plate 100. Upon detection, the sensor immediately sends a signal to the controller 330.

[0100] After receiving the signal from the first sensor 310, the controller 330 controls the drive motor 242 to start, driving the tilting component 210 to run and convey the material to the discharge port;

[0101] When the material is completely discharged and flipped towards the discharge port of component 210, the second sensor 320 detects the signal and feeds it back to the controller 330.

[0102] After receiving the signal from the second sensor 320, the controller 330 starts the cleaning program to clean the residual material in the feeding device, thus forming a closed-loop control process of "conveying-detection-cleaning".

[0103] By cooperating with the first sensor 310, the second sensor 320, and the controller 330, precise monitoring and control of the entire material conveying process can be achieved, avoiding idling or material blockage; the closed-loop control mechanism ensures seamless connection between material conveying, detection, and cleaning, improving feeding efficiency.

[0104] Delayed start cleaning procedures can promptly remove residual materials from the equipment, reduce material waste, ensure equipment cleanliness, and extend service life.

[0105] Working principle: After the equipment is powered on, the controller 330 automatically detects the status of each component, the electric lifting rod 212 resets to the initial angle, the electrostatic conveyor belt 260 completes self-test under no-load operation, and the sensor control system 300 enters standby mode.

[0106] When the first sensor 310 detects that the cotton material has entered the feeding plate 100, it sends a high-level signal to the controller 330. The controller 330 starts the drive motor 242 within a preset time, which drives the electrostatic conveyor belt 260 through the sprocket structure 241. At this time, the electrostatic scraper 254 moves synchronously with the electrostatic conveyor belt 260, and the folded compressed air plate 261 starts pulse jetting, which, together with the tilt angle of the feeding plate 100, realizes the material conveying.

[0107] When the cotton material reaches the discharge port, the second sensor 320 detects the material passing through and continuously monitors it. When the material is completely discharged, it sends a signal to the controller 330, and the controller 330 gradually reduces the speed of the drive motor 242 until it stops.

[0108] After a predetermined delay, the controller 330 starts the cleaning structure 400, the cleaning motor 440 drives the electrostatic cleaning brush 430 to rotate, and the exhaust fan 410 starts working. After 30 seconds, it automatically stops, completing one complete work cycle.
