Description

Technical Field

[0001] This utility model relates to the technical field, specifically to an upper cleaner for removing lint buildup on cradle rings. Background Technology

[0002] During the spinning process of a roving frame, short fibers easily adhere to the rollers and aprons on the cradle. If not cleaned in time, this will gradually affect the drafting effect, causing quality problems such as uneven yarn thickness in the finished yarn. Therefore, it is necessary to clean the rollers and aprons in a timely manner. The traditional cleaning method is to use a belt with a guide roller at each end, so that the lower outer surface of the belt contacts all the rollers and aprons. Through friction, the short fibers on the rollers and aprons are adsorbed and adhered to the belt. Then, a brush is used to brush away the short fibers on the belt, thereby removing the short fibers from the rollers and aprons.

[0003] Furthermore, the application document with publication number CN213113648U mentions an upper cleaner for removing lint from the cradle ring. This upper cleaner places the belt at the bottom opening of the pressing groove and presses it onto the cradle's rollers and rings. Then, the position of each sliding sleeve is adjusted so that each pressure plate presses between two adjacent rollers or between adjacent rollers and rings. The pressure plate can be bent to adjust the contact pressure of the pressure plate on the belt, so that the contact pressure between the belt and each roller and ring tends to be the same, achieving the technical goal of having an equivalent cleaning effect on each roller and ring. However, there are still some defects that need to be optimized. The specific defects are as follows: the pressure plate adjustment method is relatively complicated and inconvenient to operate, lacks a real-time pressure feedback mechanism, and cannot dynamically adjust the pressure according to the working conditions. At the same time, the existing equipment uses a one-piece brush that cannot be replaced or adjusted during brush cleaning.

[0004] Therefore, there is an urgent need to design an upper cleaner for removing lint buildup on the cradle aprons that can solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an upper cleaner for removing lint from the cradle ring, so as to solve the problems of the pressure plate adjustment method being complicated, inconvenient to operate, lacking a real-time pressure feedback mechanism, and unable to dynamically adjust the pressure according to the working conditions. At the same time, the existing equipment has a one-piece brush that cannot be replaced or adjusted when cleaning with a brush.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A top cleaner for removing lint buildup on cradle rings includes two symmetrically arranged side plates and a top plate positioned on top of the side plates. Each side plate has a trapezoidal pressing groove extending towards the top plate at the center of its lower edge. A top positioning plate is horizontally positioned at the top of each trapezoidal pressing groove. A guide wheel is positioned on each side of the trapezoidal pressing groove, and a ring-shaped belt is wound around each guide wheel. A vertically extending support plate is fixedly connected to the bottom surface of the top positioning plate. A pressing assembly is located at the bottom end of the support plate, and cleaning components are located near the two guide wheels. A controller is located on the side plate.

[0007] Furthermore, the clamping assembly includes a fixed plate disposed at the bottom of the support plate, connecting posts at the four corners of the fixed plate, a sliding rod between every two connecting posts, several sliding sleeves slidably connected to each sliding rod, connecting rods symmetrically disposed between every two symmetrical sliding sleeves, a first electric telescopic rod disposed on one side of the connecting rod, a second electric telescopic rod disposed inside the two connecting rods, a fixed box disposed at the output end of the second electric telescopic rod, a rotary motor disposed inside the fixed box, a U-shaped frame disposed at the output end of the rotary motor, and a roller disposed inside the U-shaped frame; Through the above technical solution, the first and second electric telescopic rods work together to adjust the position of the connecting rod and the fixed box. Then, the rotating motor drives the U-shaped frame and the roller to rotate, pressing the roller onto the inside of the belt. The pressure sensor feeds back pressure information to the controller in real time. The controller adjusts the extension and retraction of the electric telescopic rods according to the feedback to maintain appropriate pressure and ensure that the belt and the belt ring are in full contact during the cleaning process. At the same time, the pressure can be adjusted according to different working conditions and belt ring characteristics to ensure the adaptability and stability of the equipment.

[0008] Furthermore, the cleaning assembly includes brushes disposed on the bottom surfaces of both ends of the annular belt. The brushes are connected to the base by bolts. The bottom surface of the base is provided with several springs. The other end of the springs is connected to a guide plate. A rotating shaft is provided inside one end of the guide plate. The rotating shaft is connected to a drive motor. An inclined plate is provided between the two side plates. Through the above technical solution, the drive motor drives the rotating shaft to rotate, the rotating shaft causes the guide plate and the base to move, the base drives the brush to adjust the contact pressure between the brush and the belt, and at the same time the spring extends and retracts according to the unevenness of the belt surface, so that the brush is always in close contact with the surface of the belt, achieving a thorough cleaning of the belt.

[0009] Furthermore, the surface of the roller is provided with a rubber pad, and the roller is provided with a pressure sensor. The base is provided with a pressure sensor inside, the bottom surface of the fixed box is provided with a displacement sensor, the guide wheel is provided with tension sensors on both sides of the axial direction, and the output shaft of the rotary motor and the drive motor is provided with an angular displacement sensor. The above technical solution uses various sensors to monitor various parameters during equipment operation in real time, such as pressure, displacement, tension, and angular displacement, providing data support for the controller to achieve precise control and adjustment of the equipment.

[0010] Furthermore, the brush bristles have a double-layer structure, with an outer layer of hard nylon bristles and an inner layer of soft polytetrafluoroethylene antistatic bristles. During the cleaning process, the outer hard nylon bristles contact the surface of the rubber ring to remove accumulated lint; the inner soft polytetrafluoroethylene antistatic bristles prevent the generation of static electricity and reduce the adsorption of accumulated lint.

[0011] Furthermore, the lower opening width of the trapezoidal pressing groove is greater than the top width, the upper positioning plate is connected between the two side plates, and the upper surface of the upper positioning plate abuts against the inner surface of the annular belt, and any one of the guide wheels is located between the two side plates, and the wheel axle of the guide wheel is rotatably connected to the two side plates respectively. With the above technical solution, the annular belt is installed in the trapezoidal pressing groove, and the upper positioning plate is connected between the two side plates. Its upper surface abuts against the inner surface of the annular belt to support and position the belt, ensuring the stable operation of the belt on the equipment.

[0012] Furthermore, the upper positioning plate is bent upwards at both ends of the two side plates to form bent portions, which are fixedly connected to the two side plates respectively. The upper positioning plate has an integrally formed semi-circular convex strip at both ends facing the guide wheel. The convex strip extends from one side plate to the other side plate. The edge of any convex strip away from the center of the upper positioning plate extends vertically downwards to the bottom of the upper positioning plate to form a mounting part. Two vertically arranged limiting rods are fixedly connected to any mounting part. The annular belt is located between the two limiting rods on the same mounting part. Through the above technical solutions, the bending part enhances the connection strength between the upper positioning plate and the two side plates; the protruding strip can prevent the belt from detaching from the upper positioning plate during operation; the limiting rod can limit the horizontal displacement of the belt, ensure stable belt operation, improve the structural stability of the upper positioning plate, prevent the belt from running off-center or detaching during operation, and ensure the normal operation of the equipment.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this invention, an upper cleaner for removing lint from the cradle belt apron achieves the following effects: 1. By coordinating the first and second electric telescopic rods in the clamping assembly, the contact pressure between the roller and the belt can be precisely adjusted, ensuring full contact between the belt and the apron for uniform cleaning. Simultaneously, a rotary motor drives the U-shaped frame and roller to rotate, further improving practicality and lint removal efficiency. The clamping assembly is equipped with a pressure sensor to monitor the contact pressure between the roller and the belt in real time and feed the data back to the controller for dynamic adjustment. This closed-loop control mechanism allows the equipment to adapt to different working conditions and apron characteristics, ensuring stable pressure during cleaning; 2. The brushes in the cleaning assembly have a double-layer structure, effectively removing lint and preventing static electricity, significantly reducing secondary lint adsorption and improving cleaning efficiency.

[0018] Please see Figure 1-4 This embodiment provides an upper cleaner for removing lint buildup on cradle rings, comprising two symmetrically arranged side plates 1 and a top plate 101 positioned on top of the side plates 1. Trapezoidal pressing grooves 102 extending towards the top plate 101 are formed at the center of the lower edge of each side plate 1. An upper positioning plate 103 is horizontally positioned at the top of each trapezoidal pressing groove 102. A guide wheel 104 is positioned on each side of the trapezoidal pressing groove 102, and a ring belt 105 is wound around each guide wheel 104. A vertically downward extending support plate 106 is fixedly connected to the bottom surface of the upper positioning plate 103. A pressing assembly 2 is provided at the bottom end of the support plate 106, and cleaning assemblies 3 are respectively provided near the two guide wheels 104. A controller 4 is provided on the side plate 1. Through the coordinated work of a series of components, the overall frame of the upper cleaner is formed. The roller 211 presses against the inside of the belt 105, and the pressure is adjusted according to the feedback of the pressure sensor to ensure that the belt 105 and the belt ring are in full contact during the cleaning process. At the same time, it adapts to different working conditions and belt ring characteristics to ensure that the belt 105 and the belt ring are in full contact during the cleaning process, thereby improving the cleaning effect. The pressure can be adjusted according to different working conditions and belt ring characteristics to enhance the adaptability and stability of the equipment. The drive motor 307 drives the movement of related components, so that the brush 301 adjusts the contact pressure between itself and the belt. At the same time, the extension and retraction of the spring 303 ensures that the brush 301 is always in close contact with the surface of the belt ring, thereby cleaning the roller and belt ring.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the clamping assembly 2 includes a fixed plate 201 disposed at the bottom of the support plate 106. Connecting posts 202 are provided at the four corners of the fixed plate 201. A sliding rod 203 is provided between every two connecting posts 202.

The rotary motor 209 rotates, driving the U-shaped frame 210 and the roller 211 to rotate, so that the roller 211 presses against the inside of the belt 105. The pressure sensor feeds back pressure information to the controller in real time. The controller adjusts the extension and retraction of the electric telescopic rod according to the feedback to maintain appropriate pressure.

[0020] like Figure 1 and Figure 4 As shown, the cleaning component 3 includes brushes 301 disposed on the bottom surfaces of both ends of the annular belt 105. The brushes 301 are connected to the base 302 by bolts. The bottom surface of the base 302 is provided with several springs 303. The other end of the springs 303 is connected to the guide plate 304. One end of the guide plate 304 is provided with a rotating shaft 305, which is connected to the drive motor 307. An inclined plate 306 is provided between the two side plates 1. The bristles of the brushes 301 have a double-layer structure, with the outer layer being hard nylon bristles and the inner layer being soft polytetrafluoroethylene antistatic bristles. The drive motor 307 drives the rotating shaft 305 to rotate, which in turn causes the guide plate 304 and the base 302 to move. The base 302 drives the brush 301 to adjust the contact pressure between it and the belt 105. The spring 303 extends and retracts according to the unevenness of the belt 105 surface, so that the brush 301 is always in close contact with the belt 105 surface. During the cleaning process, the outer hard nylon bristles contact the surface of the belt ring to remove the accumulated lint, while the inner soft polytetrafluoroethylene antistatic bristles prevent static electricity from being generated and reduce the adsorption of accumulated lint.

[0021] The surface of roller 211 is equipped with a rubber pad, and a pressure sensor is installed on roller 211. A pressure sensor is installed inside the base 302. A displacement sensor is installed on the bottom surface of the fixed box 208. Tension sensors are installed on both sides of the guide wheel 104 along the axial direction. An angular displacement sensor is installed on the output shaft of the rotary motor 209 and the drive motor 307. Each sensor monitors parameters such as the pressure of the roller 211, the pressure of the base 302, the displacement of the fixed box 208, the tension of the guide wheel 104, and the angular displacement of the output shaft of the rotary motor 209 and the drive motor 307 in real time, and feeds the data back to the controller.

[0022] like Figure 1 As shown, the lower opening width of the trapezoidal crimping groove 102 is greater than the top opening width. The upper positioning plate 103 is connected between the two side plates 1, and the upper surface of the upper positioning plate 103 abuts against the inner surface of the annular belt 105. Any guide wheel 104 is located between the two side plates 1, and the axle of the guide wheel 104 is rotatably connected to the two side plates 1. The annular belt 105 is installed in the trapezoidal crimping groove 102. The upper positioning plate 103 is connected between the two side plates 1, and its upper surface abuts against the inner surface of the annular belt 105 to support and position the belt 105.

[0023] like Figure 1 As shown, the upper positioning plate 103 is bent upwards at both ends of the two side plates 1 to form bent portions 1031, which are fixedly connected to the two side plates 1. The upper positioning plate 103 has an integrally formed semi-circular convex strip 1032 at both ends facing the guide wheel 104. The convex strip 1032 extends from one side plate 1 to the other side plate 1. The edge of any convex strip 1032 away from the center of the upper positioning plate 103 extends vertically downwards to the bottom of the upper positioning plate 103 to form a mounting part. Two vertically arranged limiting rods 1034 are fixedly connected to any mounting part. The annular belt 105 is located between the two limiting rods 1034 on the same mounting part 1033. The bending part 1031 fixes the upper positioning plate 103 to the two side plates 1. The protrusion 1032 extends from one side plate 1 to the other side plate 1, preventing the belt 105 from disengaging upward. The annular belt 105 is located between the two limiting rods 1034 on the same mounting part, limiting the horizontal displacement of the belt 105.

[0024] The working process of this utility model is as follows: When using this cultural dissemination and display device, a maintenance window is first provided at the cleaning component 3 position for easy brush replacement. The vertical extension of the second electric telescopic rod 207 is adjusted by the displacement sensor. At this time, the second electric telescopic rod 207 drives the roller 211 to move downward until the pressure sensor value changes and contacts the inner side of the belt 105. Then, the first electric telescopic rod 206 is used to adjust the roller 105 to a suitable position. The positions of several rollers 105 are adjusted according to the tension sensor. If there are special requirements, such as when the leather ring being processed has a special shape or curvature, or the leather ring with a larger or smaller arc, the rotary motor 209 can be started to adjust the U according to the angular displacement sensor. The frame 210 and roller 211 rotate, causing roller 211 to press against the inside of the annular belt 105. Then the annular belt 105 runs, and the friction between the belt and the leather ring and roller removes short lint. Cleaning components 3 are provided at two points on the belt 105. First, the drive motor 307 is started by controlling the rotation of the rotating shaft 305. The rotating shaft 305 causes the guide plate 304 and the base 302 to move, which drives the brush 301 to adjust the contact pressure between itself and the annular belt 105. During the operation of the annular belt 105, the spring 303 adapts to the unevenness of the surface of the annular belt 105, so that the brush 301 is always in close contact with the surface of the annular belt 105. The outer hard nylon bristles of the brush 301 contact the surface of the leather ring to remove the accumulated lint, while the inner soft polytetrafluoroethylene antistatic bristles prevent the generation of static electricity and reduce the adsorption of accumulated lint. The cleaned short lint is discharged into the cleaner through the inclined plate.
