Description

Technical Field

[0001] This invention relates to the field of textile carding machine technology, specifically a radius calibration mechanism and method for textile carding machines. Background Technology

[0002] Currently, during the production and maintenance of textile carding machines, it is necessary to perform radius calibration on the core component, the licker-in roller. Existing calibration methods mostly involve manual handheld measuring tools for point-by-point measurement, while some methods use simple fixed gauges for single-point testing. The entire process relies on manual operation to complete the alignment, fixing, and dimensional measurement of the licker-in roller, which is not suitable for the basic calibration requirements of licker-in rollers of conventional carding machines.

[0003] Existing calibration methods have significant drawbacks: manual measurement results in large errors, poor repeatability, high labor intensity, and low testing efficiency; simple gauges can only perform local single-point testing and cannot perform all-round radius calibration of the entire circumference of the carding roller, making it difficult to accurately capture radius deviations; at the same time, they lack an integrated structure for automatic clamping, height adjustment, and rotation detection, resulting in insufficient clamping and centering accuracy, a narrow range of compatible carding roller specifications, and low automation, which cannot meet the production needs of large-scale, high-precision carding machine carding roller calibration.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0023] Please see Figure 1 In one embodiment, a textile carding machine radius calibration mechanism includes a calibration platform 1. A support frame 2 is fixed to the top of the calibration platform 1, and a lifting frame 7 is provided below the support frame 2. The lifting frame 7 is connected to the top of the support frame 2 through a lifting mechanism 3, which is used to drive the lifting frame 7 to move up and down. The inner side of the lifting frame 7 is provided with symmetrically distributed fixed rings 8, which are connected to the side wall of the lifting frame 7 through a rotating mechanism 4. The rotating mechanism 4 is used to drive the fixed rings 8 to rotate. The inner side of the fixed rings 8 is provided with a clamping mechanism 5, which is used to clamp the end of the carding machine licker-in roller. A detection mechanism 6 is installed on the top of the calibration platform 1, which is used to detect the specifications of the carding machine licker-in roller.

[0024] In this embodiment, when the verification mechanism is in use, the two ends of the carding machine licker-in roller are placed inside the two fixing rings 8 respectively. Then, the clamping mechanism 5 inside the fixing rings 8 fixes the two ends of the carding machine licker-in roller respectively. After fixing, the lifting mechanism 3 drives the lifting frame 7 to move downward. The lifting frame 7 drives the carding machine licker-in roller downward through the rotating mechanism 4 and the fixing rings 8 until the detection mechanism 6 can detect the carding machine licker-in roller. During the detection process, the rotating mechanism 4 drives the fixing rings 8 to rotate. The fixing rings 8 drive the carding machine licker-in roller to rotate through the clamping mechanism 5. This allows the testing mechanism 6 to perform comprehensive testing on the carding machine licker-in roller, thereby achieving the calibration and verification of the carding machine radius. Specifically, this carding machine radius calibration and verification mechanism uses the clamping mechanism 5 to firmly clamp both ends of the carding machine licker-in roller, and the lifting mechanism 3 to precisely control the up and down position of the licker-in roller. In conjunction with the rotating mechanism 4, the licker-in roller rotates at a uniform speed. Combined with the testing mechanism 6, it achieves comprehensive and blind-angle testing and verification of the circumference radius of the licker-in roller. The structure is reasonable, the clamping and positioning are convenient, and the degree of automation is high, which can effectively improve the comprehensiveness, accuracy, and testing efficiency of the carding machine licker-in roller radius calibration and verification.

[0025] Please see Figure 1 The lifting mechanism 3 includes hydraulic cylinders 31 installed on the top of the support frame 2 and symmetrically distributed. The extension end of the hydraulic cylinder 31 is fixed with a support rod 32, which passes through the top of the support frame 2 and is fixedly connected to the top of the lifting frame 7.

[0026] The lifting mechanism 3 uses hydraulic cylinders 31 symmetrically arranged on the top of the support frame 2. The extension end of the hydraulic cylinder 31 is connected to the support rod 32. The support rod 32 passes through the top of the support frame 2 and is fixedly connected to the lifting frame 7. The extension and retraction of the hydraulic cylinder 31 drives the support rod 32 to make vertical linear movement, thereby driving the lifting frame 7 to rise and fall smoothly as a whole, and achieving precise adjustment of the height position.

[0027] Please see Figure 1 The rotating mechanism 4 includes a motor 42 that is fixedly connected to the side wall of the lifting frame 7 and is symmetrically distributed. A rotating rod 41 is fixed on the output shaft of the motor 42. The rotating rod 41 passes through the side wall of the lifting frame 7 and is fixedly connected to the side wall of the fixing ring 8.

[0028] The rotating mechanism 4 has motors 42 symmetrically installed on both sides of the lifting frame 7. The output shaft of the motor 42 is connected to the rotating rod 41. The rotating rod 41 penetrates the side wall of the lifting frame 7 and is connected to the fixed ring 8. When the motor 42 is running, it transmits torque through the rotating rod 41, which drives the fixed ring 8 to rotate synchronously. This can drive the carding machine licker-in roller that is clamped to rotate at a uniform speed. It works with the lifting mechanism 3 to complete the height adjustment and circumferential rotation, ensuring the smooth progress of subsequent comprehensive verification and testing.

[0029] Please see Figure 2 and Figure 3 The clamping mechanism 5 includes a rotating ring 53 disposed inside the fixed ring 8. The rotating ring 53 is connected to a rotating assembly, which is used to drive the rotating ring 53 to rotate. Multiple movable rods 52 distributed in a circle are rotatably connected to the inner wall of the rotating ring 53. The other end of the movable rod 52 is rotatably connected to a stop rod 51, which penetrates the inner wall of the fixed ring 8 and is slidably connected to it.

[0030] The clamping mechanism 5 drives the rotating ring 53 inside the fixed ring 8 to rotate via a rotating component. Multiple movable rods 52 are circumferentially hinged to the rotating ring 53, and these rods 52 deflect synchronously with the rotating ring 53. The other end of each movable rod 52 is hinged to a stop rod 51, which can slide radially along the inner wall of the fixed ring 8. The rotation of the rotating ring 53 drives the movable rods 52 to swing in tandem, thereby pushing or pulling the stop rod 51 to extend and retract radially in tandem. Multiple stop rods 51 evenly press against the end of the carding machine licker-in roller from the circumferential direction, achieving centering and clamping fixation. The entire structure adopts a linkage mechanism, ensuring uniform clamping force and high centering accuracy, adapting to the clamping requirements of different licker-in roller specifications, and providing a stable positioning foundation for subsequent radius verification and rotation detection.

[0031] Please see Figure 2 and Figure 3The rotating assembly includes a gear 57 disposed inside the fixed ring 8. The outer wall of the rotating ring 53 is provided with teeth 56 distributed in a circular pattern, which mesh with the gear 57. A rotating shaft 58 passes through the inside of the gear 57 and is fixedly connected to the gear 57. The rotating shaft 58 passes through the side wall of the fixed ring 8 and is rotatably connected to it. A stop block 59 is fixed at the end of the rotating shaft 58. The stop block 59 is connected to the outer wall of the fixed ring 8 through a torsion spring 510. A fixing component is provided inside the fixed ring 8 to fix the rotating ring 53. The outer wall of the rotating ring 53 is provided with symmetrically distributed arc-shaped sliders 55. The inner wall of the fixed ring 8 is provided with symmetrically distributed arc-shaped grooves 54 that are adapted to the arc-shaped sliders 55. The end of the arc-shaped sliders 55 is located inside the arc-shaped grooves 54 and is slidably connected to them.

[0032] The rotating assembly drives the gear 57 to rotate within the fixed ring 8 via the rotating shaft 58. The gear 57 meshes with the circumferential teeth 56 on the outer wall of the rotating ring 53, driving the rotating ring 53 to rotate through gear meshing transmission. A stop 59 is provided at the end of the rotating shaft 58 and is connected to the outer wall of the fixed ring 8 via a torsion spring 510, enabling automatic reset and rotational damping limit. After the rotating shaft 58 is rotated to the correct position, the fixed component locks and fixes the rotating ring 53 to prevent it from rotating back on its own. This structure uses gear 57 and teeth 56 meshing transmission, which is smooth and precise. Combined with the torsion spring 510 for limit and the locking component for locking, it can stably control the angular position of the rotating ring 53, ensuring the reliability and stability of the centering clamping mechanism 5. The arc-shaped slide groove 54, through the arc-shaped slider 55, plays a limiting and guiding role for the rotating ring 53, improving the stability of the rotating ring 53 during rotation.

[0033] Please see Figure 4 The fixing component includes a pin 511 that passes through the side wall of the fixing ring 8. One end of the pin 511 is connected to the outer wall of the fixing ring 8 through a first spring 512, and the other end of the pin 511 is in contact with the side wall of the rotating ring 53. The side wall of the rotating ring 53 is provided with pin grooves 513 that are circumferentially distributed and adapted to the pin 511.

[0034] The pin 511 of the fixing component passes through the side wall of the fixing ring 8 and is tightened by the first spring 512, so that the end of the pin 511 abuts against the side wall of the rotating ring 53. The rotating ring 53 is provided with a matching pin groove 513 around its circumference. When the rotating ring 53 rotates to the corresponding position, the first spring 512 pushes the pin 511 into the pin groove 513 to lock the rotating ring 53. Pulling the pin 511 outward can disengage it from the pin groove 513 and unlock the rotating ring 53. The structure is simple, the locking is stable, and the operation is convenient.

[0035] Please see Figure 5The detection mechanism 6 includes a fixed frame 61 fixedly connected to the top of the calibration platform 1. Multiple slide rods 62 are equidistantly distributed inside the fixed frame 61. A detection rod 63 is fixed to the top of the slide rod 62. A first baffle 64 is fixed to the bottom of the slide rod 62. A second spring 65 is fixed to the bottom of the first baffle 64. A second baffle 66 is fixed to the bottom of the second spring 65. Multiple pressure sensors 67 are equidistantly distributed on the top of the calibration platform 1. The top of the pressure sensors 67 is connected to the second baffle 66.

[0036] The testing mechanism 6 has a fixed frame 61 on the calibration platform 1. Multiple sliding rods 62 are slidably inserted into the fixed frame 61. The upper end of the sliding rod 62 is connected to the testing rod 63, and the lower end is fixed to the first baffle 64. The first baffle 64 is connected to the lower second baffle 66 through the second spring 65. The second baffle 66 is fitted above the pressure sensor 67 on the calibration platform 1. When the carding machine licker-in roller is lowered and contacts the testing rod 63, it will press down the sliding rod 62 to move it down. The first baffle 64 compresses the second spring 65, and the pressure is transmitted to the second baffle 66 and acts on the pressure sensor 67. Relying on the second spring 65 to buffer and adapt the contact stroke, the pressure sensor 67 at each point synchronously collects the force data, thereby detecting the radius deviation of each circumferential position of the licker-in roller and realizing the accurate calibration of the radius.

[0037] Please see Figures 1-6 A method for verifying the radius gauge of a textile carding machine includes the following steps: S1. Place both ends of the carding machine licker-in roller into the two side fixing rings 8 respectively; S2, The clamping mechanism 5 inside the fixing ring 8 fixes the carding machine licker-in roller; S3, the lifting mechanism 3 drives the lifting frame 7 to move downward, so that the detection mechanism 6 can detect the carding machine licker-in roller; S4, the rotating mechanism 4 drives the carding machine licker-in roller to rotate through the fixed ring 8.

[0038] Working principle: During operation, the two ends of the carding machine licker-in roller are placed in the fixed rings 8 on both sides. The rotating ring 53 drives the circumferentially arranged movable rod 52 to swing in conjunction, causing the abutment rod 51 to slide radially, uniformly clamping the licker-in roller ends from all sides to achieve centering and clamping. The rotating shaft 58 drives the gear 57 to mesh with the teeth 56 on the outer wall of the rotating ring 53 to achieve angle adjustment. The torsion spring 510 provides a limit buffer for the rotating shaft 58. The pin 511 held by the first spring 512 can be locked into the pin groove 513 on the outer circumference of the rotating ring 53 to achieve locking and ensure stable and reliable clamping. The hydraulic cylinders 31 symmetrically arranged on the top of the support frame 2 extend and retract through the support rod 32, driving the lifting frame 7 to rise and fall smoothly and accurately adjust the vertical height of the licker-in roller, so that the licker-in roller falls to the inspection position. The motors 42 on both sides of the lifting frame 7 drive the fixed ring 8 to rotate as a whole through the rotating rod 41, causing the clamped licker-in roller to rotate circumferentially at a uniform speed. A fixed frame 61 is installed on the calibration platform 1, and multiple sliding rods 62 can slide vertically. The top detection rod 63 contacts the surface of the licker-in roller, and the lower end of the sliding rod 62 is connected to the second spring 65 via a baffle, transmitting the pressure to the bottom pressure sensor 67. As the licker-in roller rotates, it continuously contacts each detection rod 63. The second spring 65 acts as a buffer and adaptor. The pressure sensor 67 collects force data simultaneously at multiple points, accurately sensing the radius differences at various points on the circumference of the licker-in roller, completing the all-round calibration of the licker-in roller radius of the carding machine. The equipment is easy to clamp, stable to adjust, and highly automated, effectively improving calibration accuracy and detection efficiency.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
