Utility model content

The purpose of this utility model is to provide a glass fiber cloth flattening mechanism, which aims to solve the problems of the existing glass fiber cloth flattening device in the background technology, such as complex structure and poor tension control. Under the action of unfolding and tensile stress, glass fiber cloth will have some longitudinal wrinkles, and the larger the space distance, the more serious the wrinkles will be. Therefore, when the glass fiber cloth is unfolded and processed, a flattening device is usually installed between the release end and the processing end. The technical scheme adopted in the utility model is to control and flatten the release end of the glass fiber cloth. The specific scheme is as follows. A glass fiber cloth flattening mechanism includes a bracket, a magnetic powder brake, an air shaft and a flattening roller. The brake is installed on the side of the air shaft bearing seat of the bracket, the air shaft is installed on the air shaft bearing and is axially connected with the magnetic powder brake, and the flattening roller is installed on the lower part of the bracket through the flattening roller bearing , the middle side of the bracket is also provided with a cylinder, the magnetic powder brake is electrically connected with the automatic tension controller, the glass fiber cloth is placed on the air expansion shaft and bypasses the cylinder and the flattening roller, and passes through the cylinder and the flattening roller.

Preferred embodiments of the utility model are provided in the accompanying drawings. However, the invention may be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present utility model more thorough and comprehensive.

The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

As shown in Figure 1-3, a glass fiber cloth flattening mechanism includes a bracket 1, a magnetic powder brake 2, an air shaft 3 and a flattening roller 4, and the magnetic powder brake 2 is installed on the side of the air shaft bearing seat of the bracket 1. The air expansion shaft 3 is installed on the air expansion shaft bearing 31 and is axially connected with the magnetic powder brake 2. The flattening roller 4 is installed on the lower part of the bracket 1 through the flattening roller bearing 41, and the middle side of the bracket 1 is also provided with a cylinder 11. The magnetic powder brake 2 is electrically connected to the automatic tension controller, the glass fiber cloth 5 is placed on the air expansion shaft 3 and bypasses the cylinder 11 and the flattening roller 4, and the glass fiber is effectively removed by flattening the cylinder 11 and the flattening roller 4 Cloth 5 wrinkles. Among them, the magnetic powder brake 2 is based on the electromagnetic principle and utilizes magnetic powder to transmit torque. It has the characteristic that the excitation current and the transmission torque are basically linear. It can transmit a certain torque in the case of no slip, and has the advantages of fast response speed, simple structure, no pollution, no noise, no impact vibration and energy saving. With the automatic tension controller, it can detect the unwinding tension in real time, transmit the detected tension data to the automatic tension controller in real time, and change the current input to the magnetic powder brake 2 in real time according to the tension data, so as to achieve a constant tension.

The flattening roller 4 is an aluminum alloy open-width roller, adapted to the characteristics of the glass fiber cloth 5 with good toughness and strong impact resistance. The aluminum alloy open-width roller is mainly composed of an outer arc-shaped aluminum alloy hollow sheet, a roller, a tilting wheel and a mandrel, etc. Its working principle is that three groups of arc-shaped aluminum alloy hollow sheets are arranged on the surface of the roller, and the middle group Fixed on the roller, each group on both sides is inlaid in the hole groove of the roller, and the end is connected to the outwardly inclined runners on both sides. When the sheet rotates with the roller body, the sheet drives the tilting wheel to rotate, and the tilting wheel drives the sheet to reciprocate outward and inward. The sheet moves outward when turning from 0° to 180° and back when turning from 180° to 360°. When the substrate is wrapped around the sheet in the range of 0°-180°, it is flattened by the axial stretch of the outwardly moving sheet.

As shown in Figure 1, the number of air expansion shafts 3 is two, all of which are installed on the air expansion shaft bearings 31 above the bracket 1, and the air expansion shafts 3 are respectively located above the cylinder 11 and above the flattening roller 4. Magnetic powder brakes 2 are provided on both sides of the shaft 3 . When the glass fiber cloth 5 of one air shaft 3 is used up, the glass fiber cloth 5 on the other air shaft 3 can be replaced immediately to realize fast docking and improve production efficiency.

An infrared sensor is arranged on the cross bar above the flattening roller 4, and there are at least two infrared sensors, all facing the air expansion shaft 3. Wherein, the principle of the infrared sensor is to emit infrared rays toward the air shaft 3. When the air shaft 3 has glass fiber cloth 5, the infrared rays are refracted due to the rough surface of the glass fiber cloth 5, and the infrared rays returned to the infrared sensor receiver are less; When the glass fiber cloth 5 on the expansion shaft 3 will be used up, infrared rays will irradiate on the inner tube of the glass fiber cloth 5, and the inner tube will reflect more infrared rays, so that the receiver of the infrared sensor receives more infrared rays. When this signal occurs, the magnetic powder brake 2 brakes the shaft, and the traction motor stops running. One side of the flattening roller bearing 41 is offset against the support 1, and both the lateral force and the longitudinal force of the bearing are transmitted to the support 1, so that the flattening roller 4 runs more smoothly.

When the traction motor starts, the automatic tension controller monitors the tension data of the glass fiber cloth 5 in real time, and changes the current input to the magnetic powder brake 2 in real time according to the tension data, and the magnetic powder brake 2 brakes the air shaft 3 according to the current. Now, the infrared sensor monitors the running situation of the fiber cloth on the air shaft 3 in real time. More infrared rays are reflected, and then the receiver of the infrared sensor receives more infrared rays. When this signal occurs, the magnetic powder brake 2 brakes the shaft, and the traction motor stops running. The user immediately butts the glass fiber cloth 5 on the second air shaft 3, the machine runs again, and refills the glass fiber cloth 5 with the exhausted air shaft 3.

In summary, the utility model adopts the automatic tension controller and the magnetic powder brake 2 to cooperate to release the glass fiber cloth 5 with a constant force; the cylinder 11 and the aluminum alloy opening roller are used to effectively remove the wrinkles of the glass fiber cloth 5 when it is unfolded; Double air shaft 3 and infrared sensor design are used to monitor the running status of glass fiber cloth 5 in real time. When the glass fiber cloth 5 on one air shaft 3 is released, the glass fiber of the other air shaft 3 can be quickly and quickly Cloth 5, high production efficiency.
