Description

Technical Field

[0001] This utility model relates to the field of covering yarn machine technology, specifically to an anti-reverse mechanism for covering yarn machines. Background Technology

[0002] A covering yarn machine is a specialized piece of machinery used to produce covered yarn. It uses mechanical force to continuously rotate and wind the outer fiber filaments onto a uniformly drawn core filament. Twisting imparts a specific twist to the yarn, resulting in a yarn with a particular structure and style. Covering yarn machines have wide applications in the textile industry. Yarn produced by these machines not only possesses good elasticity and resilience but also offers excellent durability and comfort. A key characteristic of this type of yarn is its smooth and crisp fabric texture, making it suitable for the production of various textiles. To improve the efficiency of covering yarn machines, an anti-reverse mechanism is needed. However, existing anti-reverse mechanisms still have the following shortcomings:

[0003] When existing anti-reverse mechanisms are in use, most of them are not convenient for real-time monitoring of the operation of the covering yarn machine, resulting in untimely anti-reverse monitoring of the covering yarn machine, which affects the overall operating efficiency of the covering yarn machine and causes a decrease in the practicality and efficiency of the anti-reverse mechanism.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed an anti-reverse mechanism for covering yarn machines. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-reverse mechanism for a covering yarn machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-reverse mechanism for a covering yarn machine, comprising a receiving back plate, a speed detector, and a photoelectric detector. A positioning rod is installed at the middle of the upper end of the receiving back plate, and a speed detector is added to the front end of the positioning rod. A photoelectric detector is installed at the lower end of the positioning rod. A controller is installed on the left side of the positioning rod, and an alarm is installed above the controller. A mounting base is installed at the middle of the lower end of the receiving back plate, and an electric telescopic rod is installed at the middle of the outer side of the mounting base. A receiving frame is installed at the front end of the electric telescopic rod. Limiting sliders are added to both sides of the outer side of the receiving frame. Limiting rods are connected inside the limiting sliders. A fixed transmission roller is connected to the rear side of the inner side of the receiving frame. Mounting grooves are opened on both sides of the inner side of the receiving frame, and pneumatic rods are installed inside the mounting grooves. A movable slider is installed at the front end of the pneumatic rod, and a movable transmission roller is connected to the outside of the movable slider.

[0007] Furthermore, the positioning rods are perpendicular to the receiving back plate, and the positioning rods are fixedly connected to the receiving back plate by bolts.

[0008] Furthermore, the external dimensions of the speed detector are adapted to the internal dimensions of the positioning rod, and the speed detector and the positioning rod are embedded in each other.

[0009] Furthermore, the electric telescopic rod is perpendicular to the receiving frame, and the electric telescopic rod is fixedly connected to the receiving frame by bolts.

[0010] Furthermore, there are two limiting sliders, and the two limiting sliders are symmetrically arranged on both sides of the outside of the receiving frame with respect to the central axis of the front of the receiving frame.

[0011] Furthermore, the internal dimensions of the limiting slider are adapted to the external dimensions of the limiting rod, and the receiving frame is slidably connected to the limiting rod through the limiting slider.

[0012] Furthermore, the external dimensions of the movable slider are adapted to the internal dimensions of the mounting groove, and the movable slider is slidably connected to the receiving frame through the mounting groove.

[0013] Furthermore, there are two movable sliders, and the two movable sliders are symmetrically arranged at both ends of the outer side of the movable transmission roller with respect to the central axis of the front side of the movable transmission roller.

[0014] This utility model provides an anti-reverse rotation mechanism for a yarn covering machine, which has the following beneficial effects:

[0015] 1. This utility model, through the setting of a speed detector, enables the yarn to be conveyed in a limited manner by a positioning rod during the use of the anti-reverse mechanism of the covering yarn machine, and detects the conveying speed of the yarn by the speed detector. At the same time, the photoelectric detector monitors the operation of the covering yarn machine in real time and transmits the data to the controller. The controller analyzes and processes the data, and activates the alarm when the speed exceeds a certain range, thereby alerting the operating of the covering yarn machine and increasing the overall practicality and efficiency of the anti-reverse mechanism.

[0016] 2. This utility model, through the installation of an electric telescopic rod, enables the receiving frame to move during the anti-reverse mechanism of the covering yarn machine. Simultaneously, a limiting slider in conjunction with a limiting rod increases the stability of the receiving frame during movement. A fixed transmission roller is installed inside the rear of the receiving frame, and a pneumatic rod moves a movable slider within its mounting groove, displacing the movable transmission roller on its outer side. This allows the movable transmission roller, in conjunction with the fixed transmission roller, to transport the yarn. When the yarn transport speed slows down, the electric telescopic rod moves the receiving frame to tension the yarn, and the pneumatic rod also brings the movable and fixed transmission rollers into contact, thus limiting the yarn transport and preventing reverse yarn movement, thereby improving the overall practicality and efficiency of the anti-reverse mechanism.

Detailed Implementation

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 and Figure 2 As shown, an anti-reverse mechanism for a covering yarn machine includes a receiving back plate 1, a speed detector 3, and a photoelectric detector 4. A positioning rod 2 is installed at the upper middle part of the receiving back plate 1, and a speed detector 3 is added to the front end of the positioning rod 2. A photoelectric detector 4 is installed at the lower end of the positioning rod 2. A controller 5 is installed on the left side of the positioning rod 2, and an alarm 6 is installed above the controller 5. The positioning rod 2 is perpendicular to the receiving back plate 1, and the positioning rod 2 is fixedly connected to the receiving back plate 1 by bolts. The external dimensions of the speed detector 3 are adapted to the internal dimensions of the positioning rod 2, and the speed detector 3 is embedded in the positioning rod 2. The positioning rod 2 is fixedly installed on the upper middle part of the receiving back plate 1 by fastening bolts. The speed detector 3 is also fixedly installed inside the front end of the positioning rod 2 with fastening bolts. The positioning rod 2 is used to limit the conveying of the yarn, and the speed detector 3 detects the conveying speed of the yarn. At the same time, the photoelectric detector 4 monitors the operation of the covering yarn machine in real time and transmits the data to the controller 5. The controller 5 analyzes and processes the data, and when it exceeds a certain range, it activates the alarm 6 to alarm, thereby warning the operation of the covering yarn machine and increasing the overall practicality and efficiency of the anti-reverse mechanism.

[0023] like Figures 1 to 3As shown, a mounting base 7 is provided at the lower center of the back plate 1, and an electric telescopic rod 8 is provided at the outer center of the mounting base 7. A receiving frame 9 is installed at the front end of the electric telescopic rod 8. Limiting sliders 10 are added to both sides of the outer side of the receiving frame 9. Limiting rods 11 are connected inside the limiting sliders 10. A fixed transmission roller 12 is connected to the rear side of the inner side of the receiving frame 9. Mounting grooves 13 are opened on both sides of the inner side of the receiving frame 9, and pneumatic rods 14 are installed inside the mounting grooves 13. A movable slider 15 is provided at the front end of the pneumatic rod 14. A movable transmission roller 16 is connected to the outside of the movable slider 15. The electric telescopic rod 8 is perpendicular to the receiving frame 9. Furthermore, the electric telescopic rod 8 is fixedly connected to the receiving frame 9 by bolts. Two limiting sliders 10 are provided, symmetrically arranged on both sides of the receiving frame 9 around the front central axis. The internal dimensions of the limiting sliders 10 are adapted to the external dimensions of the limiting rod 11. The receiving frame 9 is slidably connected to the limiting rod 11 via the limiting sliders 10. The external dimensions of the movable slider 15 are adapted to the internal dimensions of the mounting groove 13, and the movable slider 15 is slidably connected to the receiving frame 9 via the mounting groove 13. Two movable sliders 15 are provided, symmetrically arranged on both sides of the front central axis of the movable transmission roller 16. The mounting base 7 is fixed to the lower middle part of the receiving back plate 1 by fastening bolts, and the electric telescopic rod 8 is fixed to the middle part of the outer side of the mounting base 7 in conjunction with the fastening bolts. The electric telescopic rod 8 drives the receiving frame 9 to move in position, and at the same time, the limiting slider 10 is fixed to both sides of the outer side of the receiving frame 9. The internal size of the limiting slider 10 is adapted to the external size of the limiting rod 11, so that the limiting slider 10 and the limiting rod 11 increase the stability of the receiving frame 9 during the movement. The fixed transmission roller 12 is limited and installed inside the rear side of the receiving frame 9, and the pneumatic rod 14 is fixed. The pneumatic rod 14 operates within the mounting slot 13 inside the receiving frame 9, driving the movable slider 15 to move within the mounting slot 13. This causes the movable transmission roller 16, located on the outside of the movable slider 15, to move. The movable transmission roller 16, in conjunction with the fixed transmission roller 12, then transports the yarn. When the yarn transport speed slows down, the electric telescopic rod 8 moves the receiving frame 9 to tension the yarn. The pneumatic rod 14, in conjunction with the movable transmission roller 16, brings the fixed transmission roller 12 into contact with the yarn, thus limiting the yarn transport and preventing reverse yarn rotation. This improves the overall practicality and efficiency of the anti-reverse mechanism.

[0024] In summary, the anti-reverse mechanism of this covering yarn machine first uses the positioning rod 2 to limit the yarn feeding, and the speed detector 3 detects the yarn feeding speed. Simultaneously, the photoelectric detector 4 monitors the operation of the covering yarn machine in real time and transmits the data to the controller 5. The controller 5 analyzes and processes the data, and when it exceeds a certain range, it activates the alarm 6 to alert the machine to the operation of the covering yarn machine. Next, the electric telescopic rod 8 moves the receiving frame 9, and the limiting slider 10, in conjunction with the limiting rod 11, further increases the movement of the receiving frame 9. To ensure stability during the process, the pneumatic rod 14 drives the movable slider 15 to move inside the mounting groove 13, thereby causing the movable transmission roller 16 on the outside of the movable slider 15 to move. The movable transmission roller 16, in conjunction with the fixed transmission roller 12, then transports the yarn. When the yarn transport speed slows down, the electric telescopic rod 8 drives the receiving frame 9 to move and tension the yarn. In conjunction with the operation of the pneumatic rod 14, the movable transmission roller 16 and the fixed transmission roller 12 are brought into contact, thereby limiting the yarn transport and preventing the yarn from reversing, thus improving the overall practicality and efficiency of the anti-reversal mechanism.
