Description

TECHNICAL FIELD

[0001] The utility model relates to a spinning technology field especially to a detection device for abnormality of friction disc of false twister. BACKGROUND

[0002] The friction disc false twister is one of main machine parts for false twist deformation. The yarn passes through the middle of three superposed friction discs, and the outer edge surface of the friction disc directly rubs the surface of the yarn to twist. The rotation directions of the three superposed discs are the same, and the discs push the yarn to rotate and advance together when rotating. The false twister twists the upstream yarn section and untwists the downstream yarn section to become the deformation yarn. The friction disc twists and untwists the yarn through friction force, and the size of the friction force affects the tension of the two ends of the yarn.

[0003] When the false twister works, the friction disc keeps running. The friction disc is a wear-resistant ceramic disc. Although the friction disc is not easy to wear, long-time high-speed work will cause wear of the friction disc, resulting in abnormality of the disc surface. The more times the high-speed running yarn contacts the friction disc, the more serious the wear of the ceramic disc. When the wear reaches a certain degree, the surface of the disc will appear concave, resulting in changes in tension during production, and changes in product tension. The difference exists in the yarn cake wound by the yarn. Even the same yarn cake will have differences in dyeing and other aspects when used because of the difference in elasticity. The number of spindle positions of the workshop false twister is huge. Generally, a workshop has thousands of false twister disc pieces. During normal detection, the factory area needs to be repaired, and all machines need to be stopped. Then the false twister is disassembled and detected one by one. The work of disassembling the false twister to check the wear degree of the disc piece is very large in time and labor, and the detection can only rely on manual observation, which is low in efficiency.

[0004] Therefore, the utility model designs a detection device for abnormality of friction disc of false twister to solve the above problems. CONTENT OF UTILITY MODEL

[0025] Please see Figs. 1 to 3 As shown, this utility model provides a detection device for abnormal friction discs of a false twister. In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] In a specific embodiment of the technical solution of this utility model:

[0027] It includes a friction disc 4, which is a circular ceramic plate. Multiple friction discs 4 are interlaced to form a travel channel for tensioned wires. The feature is that it includes: a guide rail 1, a telescopic rod 2, and a wiping block 3.

[0028] The guide rail 1 is a stable, flat base, and a drive base 11 is mounted on the guide rail 1. The drive base 11 is horizontally slidable on the guide rail 1. The drive base 11 is a linear motor, and the drive base 11 is connected to a controller. The sensor 31 and the alarm 21 are both connected to the controller for data transmission.

[0029] An alarm 21 is provided at the fixed end of the telescopic rod 2. The fixed end of the telescopic rod 2 is vertically fixed to the top of the drive base 11. The telescopic end of the telescopic rod 2 is vertically set at the top of the fixed end. A wiping block 3 is provided at the upper end of the telescopic rod 2.

[0030] The wiping block 3 is a soft block structure. The sensor 31 is installed inside the wiping block 3. The wiping block 3 is detachably and stably mounted on the telescopic end of the telescopic rod 2.

[0031] Sensor 31 is electrically connected to alarm 21, and sensor 31 is a pressure sensor.

[0032] The wiping block 3 is a sponge block. The sensor 31 is detachably embedded inside the wiping block 3. The wiping block 3 can be stably attached to the telescopic end of the telescopic rod 2 with adhesive. It can also be installed with a self-adhesive silicone sheet. This silicone sheet is removable. When the sponge is damaged by friction, different sponge covers can be replaced. When the wiping block 3 is damaged or dirty, it can be easily replaced. Alternatively, the wiping block 3 can be clipped to the upper end of the telescopic rod 2 with a locking block to ensure stable installation.

[0033] It should be noted that:

[0034] The existing method for inspecting the friction disc 4 involves visually inspecting the surface wear. Replacement is only performed when deep scratches or gaps appear. This method is inefficient and inaccurate because the depth of scratches is judged by the naked eye, not by vibration. In actual operation, the friction disc may vibrate even without scratches, especially when one side is severely worn while the other side is less worn. In this case, the friction disc has become elliptical, but the scratches are not visible to the naked eye. This can only be detected by equipment, as conventional methods cannot detect it. This is a limitation of manual inspection. Furthermore, manual inspection requires disassembling the wound yarn cake for inspection, locating the faulty equipment, and then disassembling the friction disc 4 for inspection.

[0035] This device does not have this problem. It can inspect each friction disc 4. There are tens of thousands of friction discs 4 in the entire workshop. This device can inspect them all in sequence. The inspection efficiency is high. The inspection can be completed simply by contacting and pressing the sensor 31.

[0036] In use, the height of the telescopic rod 2 is first adjusted so that the height of the wiping block 3 matches the height of the friction disc 4. Then, the drive base 11 is started, and the drive base 11 carries the wiping block 3 to slide on the guide rail 1 to wipe different friction discs 4. The sponge wiping block 3 cleans the surface of the friction disc 4. The sensor 31 detects the pressure. When the pressure fluctuates or changes, it indicates that the friction disc 4 is abnormal.

[0037] The alarm 21 is an audible and visual alarm. When it issues an alarm, the controller will stop the drive base 11, and personnel will simultaneously inspect and disassemble the friction disc 4, and test and clean the friction disc 4.

[0038] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
