Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a carding device with a fiber alignment control mechanism. Background Technology

[0002] In textile production, carding is a crucial process. Its purpose is to further open and comb the pre-processed fiber raw materials, making the fibers straighter and more parallel, removing impurities, and forming a uniform fiber layer. However, existing carding devices often suffer from insufficient fiber combing, uneven fiber arrangement, and poor adaptability to different fiber types, affecting the quality of subsequent textile products. Therefore, a carding device with a fiber alignment control mechanism is proposed. Utility Model Content

[0003] The present invention aims to provide a carding device with a fiber alignment control mechanism to solve the problems of poor fiber carding effect and uneven fiber arrangement in the prior art.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows:

[0005] A carding device with a fiber alignment control mechanism includes a housing with an inlet and an outlet opposite to each other. A carding machine is installed inside the housing, comprising a licker-in, a doffer, and a cylinder. Bearing seats are provided at both ends of the doffer. A mounting seat is provided above the carding machine corresponding to the bearing seats, and an electric push rod is fixedly connected to the mounting seat. The push rod end of the electric push rod is fixedly connected to the bearing seat. The carding gap between the licker-in and the cylinder is adjusted by driving the licker-in to move axially via the electric push rod. A feed plate is provided between the outlet and the carding machine. The carded fibers are output to the outlet in a single-layer ordered state through the feed plate. At least one combing manifold is also provided above the feed plate. The combing manifold is used to spray airflow onto the fiber layer surface to assist in fiber orientation.

[0006] Furthermore, the surfaces of the licker-in roller, doffer, and cylinder are all covered with carding cloth. The carding cloth density of the licker-in roller is greater than that of the cylinder, and the carding cloth direction of the licker-in roller and the cylinder is opposite to that of the cylinder to enhance the combing effect.

[0007] Furthermore, the angle between the feeding plate and the horizontal plane is 30°-60°, and the surface of the feeding plate is coated with polytetrafluoroethylene to reduce fiber friction resistance.

[0008] Furthermore, the comb manifolds are evenly distributed along the width of the feed plate, and the nozzle outlet direction forms an angle of 10°-20° with the fiber conveying direction.

[0009] Furthermore, the carding machine also includes a controller electrically connected to the electric push rod. The controller is signal-connected to a gap sensor, which is located at the gap between the licker-in roller and the cylinder. The gap sensor is used to detect the gap value in real time and feed it back to the controller. The controller controls the extension and retraction stroke of the electric push rod according to a preset gap threshold.

[0016] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1-3 As shown, this utility model provides a carding device with a fiber alignment control mechanism, including a housing 1, with an inlet and an outlet 2 arranged opposite to each other on the housing 1. A carding machine 11 is installed inside the housing 1. The carding machine 11 includes a licker-in roller 17, a doffer 13, and a cylinder 12. Bearing seats 14 are respectively provided at both ends of the doffer 13. A mounting seat 16 is provided above the carding machine 11 at the position corresponding to the bearing seats 14. An electric push rod 15 is fixedly connected to the mounting seat 16. The push rod end of the electric push rod 15 is fixedly connected to the bearing seat 14. The carding gap between the licker-in roller 17 and the cylinder 12 is adjusted by driving the licker-in roller 17 to move axially through the electric push rod 15. A feed plate 21 is provided between the outlet 2 and the carding machine 11. The carded fibers are output to the outlet 2 through the feed plate 21 in a single-layer orderly state. At least one combing manifold 22 is also provided above the feed plate 21. The combing manifold 22 is used to spray airflow onto the surface of the fiber layer to assist in fiber orientation and alignment.

[0018] The core structure of the carding device includes a housing 1. The feed inlet and discharge outlet 2, positioned opposite each other on the housing 1, serve as channels for fiber entry and exit. The carding machine 11 installed inside the housing 1 is the key component for realizing the carding function. It comprises three core carding components: a licker-in roller 17, a doffer 13, and a cylinder 12. The licker-in roller 17 is responsible for the initial opening and carding of the incoming fibers, while the cylinder 12 undertakes the main fine carding work. The doffer 13 collects the carded fibers and forms a fiber layer. Bearing seats 14 are located at both ends of the doffer 13, providing stable support while allowing for flexible rotation. A mounting base 16 is located above the carding machine 11 corresponding to the bearing seats 14. The mounting base 16 serves to fix the electric push rod 15, which is the power source for the adjustment mechanism. The push rod end is connected to the bearing... The seat 14 is fixedly connected. Through the extension and retraction of the electric push rod 15, the licker-in roller 17 can be driven to move axially, thereby precisely adjusting the carding gap between the licker-in roller 17 and the cylinder 12 to adapt to the carding needs of different types and states of fibers and ensure the carding effect. The feed plate 21 set between the discharge port 2 and the carding machine 11 has a flat and smooth surface. The carded fibers slide on it in a single layer in an orderly state and are finally output to the discharge port 2, ensuring the uniformity of the fibers when outputting. At least one combing manifold 22 set above the feed plate 21 will spray a stable airflow onto the surface of the fiber layer. The airflow can blow and sort out any messy fibers that may exist on the surface of the fiber layer, help the fibers maintain directional alignment, and further improve the uniformity of the fibers. Through the synergistic effect of these structures, the carding device can effectively achieve neat carding and orderly output of fibers.

[0019] The surfaces of the licker-in roller 17, doffer 13 and cylinder 12 are all covered with carding cloth. The carding cloth density of the licker-in roller 17 is greater than that of the cylinder 12, and the carding cloth directions of the licker-in roller 17 and the cylinder 12 are opposite to enhance the combing effect.

[0020] The surfaces of the licker-in roller 17, doffer 13, and cylinder 12 are all covered with card cloth, which is a component composed of finely arranged metal needles. The card cloth density on the surface of the licker-in roller 17 is greater, meaning that there are more needles per unit area than in the cylinder 12. Moreover, the direction of the needles on the card cloth of the licker-in roller 17 and the cylinder 12 is opposite. When the licker-in roller 17 and the cylinder 12 rotate relative to each other, the opposite needles can generate a stronger tearing and combing effect on the fibers. Combined with the higher card cloth density of the licker-in roller 17, it can not only more efficiently grasp and loosen the fibers, but also enhance the combing force on the fibers through the opposite action with the cylinder 12, effectively removing impurities in the fibers and making the fibers more dispersed and straightened, further improving the combing effect and making the subsequently formed fiber layer more uniform and orderly.

[0021] The angle between the feeding plate 21 and the horizontal plane is 30°-60°, and the surface of the feeding plate 21 is coated with polytetrafluoroethylene to reduce fiber friction resistance.

[0022] The feed plate 21 is tilted at an angle of 30°-60° to the horizontal plane, which can help the fiber layer slide down with the help of gravity and avoid the fiber from accumulating on the plate surface. At the same time, the polytetrafluoroethylene coating on its surface has an extremely low coefficient of friction, which can significantly reduce the frictional resistance between the fiber layer and the surface of the feed plate 21. This allows the carded single-layer ordered fibers to maintain their original arrangement during the slide, reducing fiber misalignment or entanglement caused by friction, and ensuring that the fibers are stably transported to the discharge port 2 in a neat orientation.

[0023] The comb manifolds 22 are evenly distributed along the width of the feed plate 21, and the nozzle outlet direction forms an angle of 10°-20° with the fiber conveying direction.

[0024] The comb manifolds 22 are evenly distributed along the width of the feed plate 21. This distribution ensures that the airflow uniformly covers the fiber layer across the entire width, preventing local fiber misalignment due to uneven force. At the same time, the nozzle outlet direction maintains an angle of 10°-20° with the fiber conveying direction. The ejected airflow can generate forward thrust along the fiber conveying direction to assist the smooth movement of the fiber layer, and can also generate lateral pressure on the surface of the fiber layer through the tilt angle, pressing any potentially skewed fibers toward the conveying direction, further correcting the fiber alignment, and ultimately achieving directional sorting of the fiber layer, ensuring that the output fibers always remain neat and orderly.

[0025] The carding machine 11 also includes a controller electrically connected to the electric push rod 15. The controller is signal-connected to a gap sensor, which is located at the gap between the licker-in roller 17 and the cylinder 12. The gap sensor is used to detect the gap value in real time and feed it back to the controller. The controller controls the extension and retraction stroke of the electric push rod 15 according to a preset gap threshold.

[0026] The carding machine 11 is also equipped with a controller that is connected to the electric push rod 15 via a circuit. This controller is also connected to a gap sensor located between the licker-in roller 17 and the cylinder 12. The gap sensor monitors the actual gap value between the licker-in roller 17 and the cylinder 12 in real time and feeds back the monitored data to the controller immediately. The controller has preset gap thresholds for different fiber carding requirements. When it receives the actual gap value from the gap sensor, it compares it with the preset threshold. If there is a deviation, the controller will automatically control the electric push rod 15 to perform corresponding extension and retraction movements. By adjusting the extension and retraction stroke, the gap between the licker-in roller 17 and the cylinder 12 is precisely adjusted so that it is always kept within the preset optimal carding range, thereby ensuring the stability and consistency of the fiber carding effect.

[0027] The operation of this utility model of a carding device with a fiber alignment control mechanism is as follows: The fiber raw material to be carded enters the housing 1 through the feed inlet. First, it is gripped and initially loosened by the licker-in roller 17 of the carding machine 11. The licker-in roller 17 has a higher surface density and the card cloth direction is opposite to that of the cylinder 12. Together with the cylinder 12, it performs fine carding of the fiber, removes impurities, and initially orients the fiber. The doffer 13 then gathers the carded fiber into a continuous fiber layer. During this process, the gap sensor detects the gap between the licker-in roller 17 and the cylinder 12 in real time and feeds it back to the controller. After comparing with the preset threshold, the doffer 13 is driven to move axially by the electric push rod 15 to precisely adjust the gap between the two to adapt to the fiber characteristics. The combed single-layer ordered fibers enter the feed plate 21 at an angle of 30°-60° with the horizontal plane. The polytetrafluoroethylene coating on the surface of the feed plate 21 reduces frictional resistance, allowing the fibers to slide down smoothly. At the same time, the combing manifolds 22, which are evenly distributed along the width of the feed plate 21, spray air at an angle of 10°-20° with the fiber conveying direction to help correct the fiber arrangement. Finally, the fibers are output through the discharge port 2 in a neat and oriented state.
