Description

Technical Field

[0001] This utility model relates to the field of spinning machine technology, and in particular to a low-friction tray rotating device for spinning machines. Background Technology

[0002] In the yarn processing of a spinning machine, yarn bobbin finding is a crucial step, requiring the bobbin to rotate smoothly to quickly locate the yarn end. However, traditional rotating devices often suffer from high friction, leading to uneven bobbin rotation, increasing the time and difficulty of finding the yarn end, and consequently affecting the overall production efficiency of the spinning machine. Furthermore, the heat and wear generated by friction can damage the yarn, reducing its quality. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] In view of the problems existing in the current low-friction tray rotation device for spinning machines, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a low-friction tray rotating device for spinning machines, which is suitable for solving the problems of high friction in traditional rotating devices, which often cause the yarn tube to rotate poorly, increase the time and difficulty of finding the yarn head, affect the production efficiency of spinning machines, and cause friction heat and wear to damage the yarn and reduce its quality.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a low-friction tray rotating device for a spinning machine, comprising:

[0007] The main unit includes a rotating base plate;

[0008] The friction reduction unit includes a ceramic rotor;

[0009] The yarn condition monitoring unit includes a light source emitter, which is symmetrically mounted on the top of a rotating base plate. Photoelectric elements are symmetrically mounted on the top of the rotating base plate, and the photoelectric elements and the light source emitter are located on both sides of a ceramic rotor. A controller is provided on one side of the rotating base plate, and the controller is wired to the light source emitter and the photoelectric elements respectively.

[0010] As a preferred embodiment of the low-friction tray rotating device for a spinning machine described in this utility model, the ceramic rotor includes a through groove, which is symmetrically opened at the top of the rotating base plate and is rotatably connected to the ceramic rotor.

[0011] In a preferred embodiment of the low-friction tray rotating device for a spinning machine described in this utility model, the controller includes a mounting groove, which is formed on one side of the rotating base plate and is used in conjunction with the controller.

[0012] As a preferred embodiment of the low-friction tray rotating device for a spinning machine described in this utility model, the rotating base plate includes threaded columns, which are symmetrically installed at the top of the rotating base plate.

[0013] As a preferred embodiment of the low-friction tray rotating device for a spinning machine described in this utility model, the rotating base plate further includes anti-slip textures, which are disposed on the bottom surface of the rotating base plate.

[0014] As a preferred embodiment of the low-friction tray rotating device for a spinning machine described in this utility model, the ceramic rotor further includes a wear-resistant coating, which is uniformly coated on the outer surface of the ceramic rotor.

[0015] In a preferred embodiment of the low-friction tray rotating device for a spinning machine described in this utility model, the light source emitter is an adjustable light source, the brightness or light intensity of which can be adjusted by a controller.

[0016] In a preferred embodiment of the low-friction tray rotation device for a spinning machine described in this utility model, the controller further includes a signal processing module, which is capable of filtering, amplifying, and digitizing the electrical signals output by the photoelectric element.

[0017] The beneficial effects of this utility model are:

[0018] 1. When the rotating base plate rotates, the ceramic rotor rotates synchronously. During the rotation of the yarn, the yarn enters from one side of the slot, passes around the outer surface of the ceramic rotor, and contacts the low-friction coating of the ceramic rotor. Finally, it exits from the other side of the slot. Due to the low-friction characteristics of the ceramic rotor, the yarn can move smoothly on its surface. This design significantly reduces the friction between the yarn and the rotating parts, thereby reducing the heat and wear generated by friction. It effectively protects the quality and integrity of the yarn and solves the problems of high friction in traditional rotating devices, which often cause the yarn tube to rotate poorly, increase the time and difficulty of finding the yarn head, affect the production efficiency of the spinning machine, and cause friction heat and wear to damage the yarn and reduce its quality.

[0019] 2. The light source emitter continuously projects light onto the photoelectric element, constructing a stable optical path monitoring system. During normal yarn spinning, the yarn partially blocks or reflects light, causing regular changes in the light intensity received by the photoelectric element. The photoelectric element keenly captures these changes, accurately converts them into electrical signals, and transmits them to the controller in real time. When the yarn condition is stable, the electrical signal output by the photoelectric element is stable. Based on this, the controller judges that the yarn is in a normal spinning state and continuously monitors the signal to ensure real-time control of the yarn condition. Once the yarn breaks, the light that was originally blocked or reflected changes significantly, such as reduced blocking or disappearance of reflection, causing a sharp change in the light intensity received by the photoelectric element. This sudden change in light intensity is immediately converted into a change in electrical signal by the photoelectric element and quickly transmitted to the controller. After receiving the abnormal electrical signal, the controller immediately starts the preset program, quickly judges that the yarn has broken, and triggers corresponding actions, such as emergency stop of the spinning machine, alarm, or automatic activation of the splicing device. This avoids production accidents and quality problems caused by yarn breakage, significantly improves the working efficiency and stability of the spinning machine, and reduces the cost and labor intensity of manual inspection.

[0029] Reference Figure 1 - Figure 3 As an embodiment of the present invention, a low-friction tray rotating device for a spinning machine is provided, including a main body unit 100, a friction reduction unit 200 and a yarn condition monitoring unit 300.

[0030] The main unit 100 includes a rotating base plate 101, which serves as a support and rotating platform for the yarn tube. The rotating base plate 101 is made of high-strength, lightweight material to ensure its stability and durability.

[0031] The friction reduction unit 200 includes a ceramic rotor 201. Since the ceramic rotor 201 is installed in the through groove of the rotating base plate 101, when the rotating base plate 101 rotates, the ceramic rotor 201 will rotate along with it. When the yarn comes into contact with the ceramic rotor 201 during rotation, the yarn can move smoothly due to the low friction characteristics of the ceramic rotor 201. This reduces the friction between the yarn and the rotating parts, reduces the heat and wear generated by friction, and thus protects the quality and integrity of the yarn. It solves the problems of high friction in traditional rotating devices, which often cause the yarn tube to rotate poorly, increase the time and difficulty of finding the yarn head, affect the production efficiency of the spinning machine, and cause friction heat and wear to damage the yarn and reduce its quality.

[0032] The yarn condition monitoring unit 300 includes a light source emitter 301, which is symmetrically mounted on the top of the rotating base plate light source emitter 101. Photoelectric elements 302 are symmetrically mounted on the top of the rotating base plate 101, and the photoelectric elements 302 and the light source emitter 301 are located on opposite sides of the ceramic rotor 201. A controller 303 is located on one side of the rotating base plate 101, and the controller 303 is wired to both the light source emitter 301 and the photoelectric element 302. The light source emitter 301 (light-emitting diode (LED), laser emitter, etc.) continuously projects light onto the photoelectric element 302, forming a stable optical path monitoring system. During normal yarn weaving, the yarn partially blocks or reflects this light, causing a regular change in the light intensity received by the photoelectric element 302. The photoelectric element 302 sensitively captures these light intensity changes and accurately converts them into electrical signals, which are transmitted to the controller 303 in real time. When the yarn condition is stable, the photoelectric element... The electrical signal output by 302 remains stable, and the controller 303 determines that the yarn is in a normal spinning state based on this signal. It continuously monitors this signal to ensure real-time control of the yarn status. Once the yarn breaks, the light that was originally blocked or reflected by the yarn will change significantly, such as the reduction of blocking or the disappearance of reflection. This causes a sharp change in the light intensity received by the photoelectric element 302. This sudden change in light intensity will be immediately converted into a change in electrical signal by the photoelectric element 302 and quickly transmitted to the controller 303. After receiving this abnormal electrical signal, the controller 303 will immediately start the preset program (when a yarn break is detected), quickly determine that the yarn has broken, and trigger corresponding actions, such as emergency stop of the spinning machine, issuing an alarm to remind the operator, or automatically starting the splicing device. This avoids production accidents and quality problems caused by yarn breakage, significantly improves the working efficiency and stability of the spinning machine, and reduces the cost and labor intensity of manual inspection.

[0033] The ceramic rotor 201 includes a through slot 201a, which is symmetrically opened at the top of the rotating base plate 101 and rotatably connected to the ceramic rotor 201. It is used to mount the ceramic rotor 201 on the rotating base plate 101. During rotation, the yarn enters from one side of the through slot 201a, bypasses the outer surface of the ceramic rotor 201, contacts the low-friction coating of the ceramic rotor 2021, and then exits from the other side. This significantly reduces the friction between the yarn and the rotating parts, reduces the heat and wear generated by friction, and thus protects the quality and integrity of the yarn.

[0034] The controller 303 includes a mounting slot 303a, which is formed on one side of the rotating base plate 101 and is used in conjunction with the controller 303 to mount the controller 303 on the rotating base plate 101.

[0035] The rotating base plate 101 includes threaded posts 101a, which are symmetrically mounted on the top of the rotating base plate 101, so as to facilitate the connection of the rotating base plate 101 with a motor or other drive device and provide rotational power for the rotating base plate 101.

[0036] The rotating base plate 101 also includes anti-slip textures, which are provided on the bottom surface of the rotating base plate 101 to increase the friction between the rotating base plate 101 and the mounting surface, prevent the device from sliding during operation, and ensure the stability and safety of the device.

[0037] The ceramic rotor 201 also includes a wear-resistant coating, which is uniformly coated on the outer surface of the ceramic rotor 201 to improve the wear resistance of the ceramic rotor 201, extend its service life, and reduce the impact of wear-generated debris on yarn quality. At the same time, the wear-resistant coating also has good lubrication properties, which can further reduce the friction between the ceramic rotor 201 and the yarn and improve the smoothness of yarn movement.

[0038] The light source emitter 301 is an adjustable light source, and its brightness or light intensity can be adjusted by the controller 303 to adapt to different ambient lighting conditions or differences in the light reflection characteristics of yarn materials, so as to ensure that the photoelectric element 302 can accurately detect changes in the state of the yarn.

[0039] The controller 303 also includes a signal processing module, which can filter, amplify and digitize the electrical signal output by the photoelectric element 302 to improve the stability and reliability of the signal, reduce the possibility of misjudgment and missed judgment, and thus more accurately determine whether the yarn is broken or in an abnormal state.

[0040] During use, when the rotating base plate 101 rotates, the ceramic rotor 201 rotates synchronously. During the rotation of the yarn, the yarn enters from one side of the slot 201a, bypasses the outer surface of the ceramic rotor 201, contacts the low-friction coating of the ceramic rotor, and finally exits from the other side of the slot 201a. Due to the low-friction characteristics of the ceramic rotor 201, the yarn can move smoothly on its surface. This design significantly reduces friction between the yarn and the rotating components, thereby reducing heat and wear caused by friction, effectively protecting the quality and integrity of the yarn. The light source emitter 301 continuously projects light onto the photoelectric element 302, forming a stable optical path monitoring system. During normal yarn weaving, the yarn partially blocks or reflects this light, causing regular changes in the light intensity received by the photoelectric element 302. The photoelectric element 302 sensitively captures these light intensity changes and accurately converts them into electrical signals, transmitting them to the controller 303 in real time. When the yarn is stable, the electrical signal output by the photoelectric element 302 remains stable. Based on this, the controller 303 determines that the yarn is in a normal spinning state and continuously monitors this signal to ensure real-time control of the yarn status. Once the yarn breaks, the light that was originally blocked or reflected by the yarn will change significantly, such as the reduction of blocking or the disappearance of reflection, resulting in a sharp change in the light intensity received by the photoelectric element 302. This sudden change in light intensity will be immediately converted into a change in electrical signal by the photoelectric element 302 and quickly transmitted to the controller 303. After receiving this abnormal electrical signal, the controller 303 will immediately start the preset program - when a yarn break is detected - to quickly determine that the yarn has broken and trigger corresponding actions, such as emergency stop of the spinning machine, issuing an alarm to remind the operator, or automatically starting the splicing device, etc. This avoids production accidents and quality problems caused by yarn breakage, significantly improves the working efficiency and stability of the spinning machine, and reduces the cost and labor intensity of manual inspection.
