Description

Technical Field

[0001] The utility model relates to the field of spinning frames, in particular to a tube feeding belt device of a spinning frame. Background Art

[0002] In the current existing technology, the tube feeding mechanism of the spinning frame is driven by a synchronous toothed belt, which uses a motor as the output power source. The motor and the synchronous pulley are installed on the corresponding frame through bearings, and a transmission shaft is installed on the side of the synchronous pulley for outputting power. The transmission shaft is connected to the tube feeding mechanism of the spinning frame, and the transmission is realized by the motor driving the synchronous toothed belt to operate, thereby driving the tube feeding mechanism of the spinning frame to feed the spinning tube into the running platform.

[0003] However, when feeding the tubes, two or more tubes are often fed together, causing the feeding tube part to be stuck, while the toothed belt motor is still working, eventually causing the toothed feeding tube belt to be broken or the motor to be overloaded and damaged; therefore, a spinning frame feeding tube belt device is proposed to address the above problems. Utility Model Content

When in use, the motor drives the upper transmission roller to rotate, and then the smooth transmission leather plate is used to replace the synchronous toothed belt for transmission. When the motor encounters a larger load (stuck tube) during work, the smooth transmission leather plate can slide, the motor can operate normally, and the leather plate driven by the motor stops working. In this way, it is ensured that the transmission leather plate is not damaged, and the motor is protected from damage. The transmission leather plate is a widened belt.

[0007] Preferably, a plurality of heat dissipation cavities are provided inside the upper transmission roller and the lower transmission roller; a plurality of heat dissipation fins are fixedly connected to the inner side wall of the heat dissipation cavity. By providing the heat dissipation cavities inside the upper transmission roller and the lower transmission roller, the heat dissipation area can be increased during rotation, so that the upper transmission roller and the lower transmission roller can be cooled down when the feeding tube is stuck. The heat dissipation fins are used to increase the area in contact with the air to facilitate heat dissipation.

In this way, it is ensured that the transmission leather plate 14 is not damaged, and the motor 16 is protected from damage. The transmission leather plate 14 is a widened belt.

[0024] Further, such as Figure 1-2 As shown in 4, the tensioning adjustment assembly includes two screw rods 23, two adjustment seats 22 and a tensioning roller 24; two pairs of guide rods 21 are fixedly connected to the side of the frame 11; the adjustment seat 22 is slidably connected to the guide rod 21; the screw rod 23 passes through the adjustment seat 22 and is threadedly connected thereto; the tensioning roller 24 is rotatably connected between the two adjustment seats 22; the tensioning roller 24 is in contact with the transmission leather plate 14; when in use, by relying on the two screw rods 23, the adjustment seat 22 can be driven to move by rotating the screw 23, and then the tensioning roller 24 can be driven to move, so as to adjust the tensioning force of the transmission leather plate 14, thereby reducing the situation where the smooth transmission leather plate 14 is often stretched by external force, causing the transmission leather plate 14 to slip during transmission.

[0025] Further, such as Figure 3 , 5 As shown, a plurality of heat dissipation cavities 31 are provided inside the upper transmission roller 12 and the lower transmission roller 13; a plurality of heat dissipation fins 32 are fixedly connected to the inner wall of the heat dissipation cavity 31; when in use, the heat dissipation cavity 31 is provided inside the upper transmission roller 12 and the lower transmission roller 13, which can increase the heat dissipation area during rotation, and facilitate cooling of the upper transmission roller 12 and the lower transmission roller 13 when the feeding tube is stuck, and the heat dissipation fins 32 are used to increase the area in contact with the air to facilitate heat dissipation.

[0026] Further, such as Figure 3As shown, one end of the upper transmission roller 12 away from the motor 16 and one end of the lower transmission roller 13 away from the transmission shaft 15 are both rotatably connected to the air guide cover 41; the ends of the upper transmission roller 12 and the lower transmission roller 13 are fixedly connected to the rotating shaft 42; the fan blades 43 are fixedly connected to the rotating shaft 42; the fan blades 43 are located inside the air guide cover 41; the air guide cover 41 is fixedly connected to the frame 11; when in use, the upper transmission roller 12 and the lower transmission roller 13 rotate, which causes the rotating shaft 42 and the fan blades 43 to rotate, and the rotation of the fan blades 43 will suck air into the air guide cover 41, and then send it into the heat dissipation cavity 31 through the air guide cover 41, so that the upper transmission roller 12 and the lower transmission roller 13 can be cooled and cooled. When the feeding pipe of the winding tube is stuck, it can reduce the temperature during friction, thereby improving the cooling effect.

[0030] Working principle: when in use, the motor 16 drives the upper transmission roller 12 to rotate, and then the smooth transmission leather plate 14 is used to replace the synchronous toothed belt for transmission. When the motor 16 encounters a large load during work (stuck pipe), the smooth transmission leather plate 14 can slide, the motor 16 can operate normally, and the leather plate driven by the motor 16 stops working. In this way, it is ensured that the transmission leather plate 14 is not damaged and the motor 16 is protected from damage. The transmission leather plate 14 is a widened belt, relying on the two screws 23 set up. By rotating the screw 23, the adjustment seat 22 can be driven to move, and then the tensioning roller 24 can be driven to move, so as to adjust the tensioning force of the transmission leather plate 14, thereby reducing the smooth transmission leather plate 14 often being stretched by external force, causing the transmission leather plate 14 to slip during transmission. By opening a heat dissipation cavity 31 inside the upper transmission roller 12 and the lower transmission roller 13, it can increase the heat dissipation area during rotation, which is convenient for the upper transmission when the feeding tube is stuck. The cooling fins 32 are used to increase the contact area with the air to facilitate heat dissipation. During the rotation of the upper and lower transmission rollers 12 and 13, the rotating shaft 42 and the fan blades 43 are rotated. The rotation of the fan blades 43 will inhale air into the wind guide cover 41, and then send it to the inside of the heat dissipation chamber 31 through the wind guide cover 41, so that the upper and lower transmission rollers 12 and 13 can be cooled. When the feeding tube of the winding tube is stuck, it can reduce the temperature during friction, which plays a role in improving the cooling effect. Relying on this setting, the transmission leather plate 14 can be pressed, and then the contact area between the transmission leather plate 14 and the upper and lower transmission rollers 12 and 13 can be increased, so that it is convenient to drive the transmission leather plate 14 to move, and then it can be convenient to transmit. The inhaled air can be filtered by relying on the filter plate 6, so as to reduce the dust accumulation and foreign matter entering the heat dissipation chamber 31, and reduce the impact on the heat dissipation effect.
