Description

Technical Field

[0001] This utility model relates to the field of traction and guidance technology, and in particular to an adjustable fabric traction and guidance limiting device. Background Technology

[0002] Cotton fabrics are characterized by high elasticity, easy wrinkling, and uneven thickness. During high-speed transport in production, problems such as deviation, excessive stretching, or loose accumulation can easily occur, leading to dimensional deviations in subsequent dyeing and cutting processes and affecting the finished product qualification rate. Therefore, traction guide and limiting structures need to be set up in the production and transport of cotton fabrics to traction, guide, and limit the fabric.

[0003] However, existing cotton traction guide and limiting structures are usually in a fixed position, making it inconvenient to adjust the gap between them and the cotton according to the thickness of the cotton and the transmission requirements, which makes them rather inconvenient to use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose an adjustable fabric traction guide and limiting device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides an adjustable fabric traction guide and limiting device, including a conveyor frame for traction and transmission of cotton material. One end of the conveyor frame is equipped with a detection rod group for detecting the cotton material. The detection rod group is signal-connected to a control module for signal processing and automated control. The control module is signal-connected to a lifting traction seat for lifting control. A laser rangefinder sensor for detecting the height of the lifting traction seat is fixedly installed at its bottom. A wire brush for traction and guidance of the cotton material is installed inside the lifting traction seat. A pressure detection rod that adheres to the surface of the cotton material is located at the center of the wire brush. A pressure detection block that withstands pressure is fixedly installed inside the pressure detection rod. A fastening insert for detaching and reassembling the pressure detection rod is fixedly installed at its top. The control module is located inside the conveyor frame and is signal-connected to the conveying transmission structure inside the conveyor frame. It can also be powered by an external power system. The conventional control module inside the control module enables automated mechanical control of the entire device. A digital control screen can be set up to display the detection data during operation and to control and adjust various structures based on the detection data, ensuring the stable operation of the entire device.

[0006] Preferably, in any of the above embodiments, the conveyor frame is provided with a conveyor roller assembly that is signal-connected to the control module and driven by a motor, and a cotton cloth for conveying is placed on top of the conveyor roller assembly.

[0007] The above technical solution is adopted: the conveyor roller group driven by the motor inside the conveyor frame realizes closed-loop speed control through the control module. The rollers are coated with silicone to clamp the cotton material with a certain pressure to avoid slippage. The spacing of the conveyor roller group is preset according to the thickness of the cotton material to ensure smooth transmission and provide stable feed for subsequent traction guidance.

[0008] Preferably, in any of the above embodiments, the detection rod assembly includes a detection bracket for support and a laser sensor for detecting the size of the cotton fabric. The detection bracket is fixedly installed at one end of the top of the conveyor frame, and the laser sensor located above the cotton fabric is fixedly installed at the top of the detection bracket.

[0009] The above technical solution is adopted: the detection bracket (aluminum alloy profile) is fixed at the entrance end of the conveyor frame, and the top laser sensor scans the width and edge position of the cotton material at a certain frequency. When the width of the cotton material deviates or the edge shifts, the sensor sends a signal to the control module to trigger the subsequent guide adjustment action and realize the pre-inspection and early warning.

[0010] Preferably, the lifting traction seat includes a lifting base for support and fixation, a pneumatic telescopic rod connected to the control module signal, and a lifting seat for lifting support. The lifting base is fixedly installed on the top of the conveyor frame, the pneumatic telescopic rod is fixedly installed inside the lifting base, and the lifting seat that moves inside the lifting base is fixedly installed at the top of the pneumatic telescopic rod.

[0011] The above technical solution is adopted: the lifting base (Q235 steel) is fixed to the conveyor frame by bolts, and the internal pneumatic telescopic rod is driven by the PWM signal of the control module to drive the lifting base (aluminum alloy material) to rise and fall along the guide rail. The adjustment response time is fast and the distance between the wire brush and the cotton material can be automatically adjusted according to the thickness of the cotton material.

[0012] Preferably, in any of the above embodiments, the laser rangefinder is fixedly installed at the bottom of one end of the lifting base, the laser rangefinder is located inside the lifting base, and the laser rangefinder is located on one side of the pneumatic telescopic rod.

[0013] The above technical solution is adopted: the laser rangefinder sensor detects the distance between the lifting seat and the lifting base in real time, and the data is transmitted to the control module for comparison with the preset height to form a closed-loop control, ensuring the height positioning accuracy of the wire brush.

[0014] Preferably, in any of the above embodiments, the wire brush includes a rotating shaft for support and a steel brush for squeezing the cotton cloth. The rotating shaft is fixedly installed inside the lifting seat, and a steel brush is rotatably connected to one end of the rotating shaft. The pressure detection rod is engaged with one end of the rotating shaft and located on one side of the steel brush.

[0015] The above technical solution is adopted: the rotating shaft is fixed to the lifting seat through bearings, and drives the steel brush to rotate passively with the cotton material transmission (the rotation speed is matched with the conveying speed). The steel brush adheres to the surface of the cotton material with a certain pressure, and generates lateral guiding force while combing the fibers to correct the cotton material deviation.

[0016] Preferably, in any of the above embodiments, the pressure detection block includes a pressure sensor connected to the control module signal and a pressure-bearing extrusion block. The pressure sensor is fixedly installed inside the pressure detection rod, and the extrusion block located inside the pressure detection rod is fixedly installed at the detection end of the pressure sensor.

[0017] Using the above technical solution: the pressure sensor detects the contact pressure between the steel brush and the cotton material through the extrusion block (polyurethane material), and the signal is transmitted to the control module in real time.

[0018] Preferably, in any of the above embodiments, the fastening rod includes a fastening spring for support and a fastening block for engaging and positioning the pressure detection rod. The fastening spring is fixedly installed inside the pressure detection rod, and the top of the fastening spring is fixedly installed with a fastening block movably connected inside the pressure detection rod.

When disassembling, the rod can be pulled out by pressing the block to compress the spring, which facilitates the maintenance and calibration of the pressure detection component.

[0020] The cotton material enters the conveyor frame, the conveyor rollers start transmission, the laser sensor of the detection rod group scans the size and transmits data, the control module calculates the lifting height based on the cotton material thickness, drives the pneumatic telescopic rod to adjust the lifting seat, the laser rangefinder provides real-time feedback on the height and performs calibration, the wire brush contacts the cotton material, the pressure detection block detects the contact pressure, and the control module fine-tunes the pressure through the telescopic rod. During transmission, if the cotton material deviates or the pressure is abnormal, the system adjusts the height of the wire brush and the guiding force in real time to ensure stable transmission of the cotton material. When the laser sensor detects that the edge of the cotton material deviates or the pressure sensor detects that the pressure may damage the cotton material, the control module immediately reduces the conveying speed and issues an alarm. Operation resumes after manual intervention.

[0023] 2. A pressure detection rod is installed on one side of the wire brush to support the pressure detection block, so that the pressure detection rod rises and falls with the movement of the wire brush. This allows for the detection of the pressure between the wire brush and the cotton material, facilitating precise adjustment of the wire brush position based on the detection data.
