The present invention provides the following technical solution: a sliver conveying device for a drawing frame, comprising a guiding mechanism 1 and a conveying mechanism 2, wherein the conveying mechanism 2 is movably connected to the top of the guiding mechanism 1.

[0023] The conveying mechanism 2 includes a tension adjustment unit and a transmission unit. The tension adjustment unit is movably connected to the top of the guide mechanism 1, and the transmission unit is movably connected to the top of the guide mechanism 1.

[0024] The guiding mechanism 1 consists of a base 101, a guide support frame 102, a guide roller 103, a threaded groove 104, a threaded rod 105, an adjusting motor 106, and a limiting rod 107. The guide support frame 102 is fixedly connected to the top of the base 101, the guide roller 103 is rotatably connected to the inside of the guide support frame 102, the threaded groove 104 is opened at the top of the base 101, the threaded rod 105 is rotatably connected to the inside of the threaded groove 104, the adjusting motor 106 is fixedly connected to both sides of the threaded groove 104, and the limiting rod 107 is threadedly connected to the inside of the threaded groove 104, playing the main supporting and guiding role, ensuring that the cotton strip is in a centered state, and avoiding subsequent conveying problems caused by the cotton strip being skewed.

[0025] The tension adjustment unit consists of a cylinder 201, a lifting bracket 202, a lifting rod 203, a connecting block 204, and a tension adjustment roller 205. The cylinder 201 is fixedly connected to the top of the base 101, the lifting bracket 202 is fixedly connected to the top of the cylinder 201, the lifting rod 203 is movably connected inside the lifting bracket 202, the connecting block 204 is fixedly connected to the top of the lifting rod 203, and the tension adjustment roller 205 is rotatably connected to the side of the connecting block 204. A pressure sensor is installed at the connection end between the tension adjustment roller 205 and the connecting block 204, primarily detecting the pressure between the tension adjustment roller 205 and the cotton sliver, maintaining a stable pressure to ensure stable tension of the cotton sliver. When the cotton sliver passes through, it can automatically expand and contract according to changes in cotton sliver tension, serving as a buffer and adjusting tension. The transmission unit consists of a transmission bracket 21. 1. The system comprises a hydraulic assembly 212, a telescopic rod 213, a connecting frame 214, a transmission motor 215, and a transmission roller 216. The transmission support 211 is fixedly connected to the top of the base 101. The hydraulic assembly 212 is fixedly connected to the side of the transmission support 211.

[0026] In use, the swab first passes through the guiding mechanism 1. The guide roller 103 within the guide support frame 102 on the base 101, driven by the adjusting motor 106 and the threaded rod 105, engages with the limiting rod 107 to ensure the swab is aligned. It then enters the conveying mechanism 2. The cylinder 201 of the tension adjusting unit adjusts the height of the lifting bracket 202 based on feedback from the pressure sensor, causing the tension adjusting roller 205 to automatically extend and retract according to changes in swab tension to buffer and adjust the tension. Finally, the transmission unit operates. The hydraulic component 212 on the transmission bracket 211 drives the telescopic rod 213, which in turn drives the conduction motor 215 within the connecting frame 214, causing the conduction roller 216 with a rubber surface to rotate, clamping and stably conveying the swab.
