Description

Technical Field

[0001] This utility model relates to the field of glass fiber cloth trimming, specifically to an anti-deviation trimming machine for glass fiber cloth. Background Technology

[0002] Glass fiber is a high-performance inorganic non-metallic material with many varieties. Its advantages include good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. However, its disadvantages include brittleness and poor wear resistance. It is produced from glass spheres or waste glass through high-temperature melting, drawing, winding, and weaving processes. The diameter of its single filaments ranges from a few micrometers to over twenty micrometers, and each bundle of fiber consists of hundreds or even thousands of single filaments. Glass fiber is commonly used as a reinforcing material in composite materials, as well as in electrical insulation, thermal insulation, and circuit boards, among other applications in various sectors of the national economy. In the production of glass fiber cloth, problems such as rough edges and curled edges exist on the sides, requiring edge trimming. Current edge trimming machines tend to shift the glass fiber cloth during cutting, affecting the cutting effect. Utility Model Content

Detailed Implementation

[0018] Example 1

[0019] like Figures 1 to 3 As shown, a fiberglass cloth anti-deviation trimming machine includes a trimming platform 1. Conveyor belts 2 and limiting plates 3 are sequentially arranged on both sides of the trimming platform 1 along the fiberglass cloth conveying direction. The limiting plates 3 have a degree of freedom of movement perpendicular to the fiberglass cloth conveying direction, and the two limiting plates 3 move in opposite directions. Trimming blades 4 are rotatably arranged above both conveyor belts 2, and the cutting surface of the trimming blades 4 is flush with the inner surface of the limiting plate 3 on the same side. Unwinding and rewinding devices are respectively arranged at both ends of the trimming platform 1. The fiberglass cloth to be trimmed is then rewound... The fiberglass cloth is wound onto an unwinding device, which is located near the conveyor belt 2. After being trimmed, the fiberglass cloth is wound onto the winding device. During the conveying process of the fiberglass cloth, two limiting plates 3 limit the fiberglass cloth, so that the trimmed fiberglass cloth is confined between the two limiting plates 3 for conveying. The trimming blade 4 cuts off the rough edges and rolled edges that exceed the limiting plates, completing the conveying and trimming of the fiberglass cloth, which improves the trimming efficiency and trimming effect. The trimmed debris falls onto the conveyor belt 2, which transports the debris to a designated location.

[0020] Furthermore, a motor base 11 is installed on the outer side of the limiting plate 3, and a motor 12 is installed on the motor base 11. The output shaft of the motor 12 is connected to the trimming blade 4. By installing the motor 12 on the limiting plate 3, the trimming blade 4 can move together with the limiting plate 3 to adapt to the width of the fiberglass cloth for trimming operations.

[0021] Example 2

[0022] Based on Example 1, such as Figure 1 and Figure 3As shown, tensioning mechanisms are provided at both ends of the trimming platform 1. Each tensioning mechanism includes a frame 17, within which an upper rubber roller 18 and a lower rubber roller 19 are rotatably mounted. Fiberglass cloth passes between the upper and lower rubber rollers 18 and 19. The top surface of the lower rubber roller 19 is flush with the top surface of the trimming platform 1. A lifting cylinder 20 is vertically mounted on the frame 17. The telescopic shaft of the lifting cylinder 20 is connected to a C-shaped frame 21. The upper rubber roller 18 is rotatably mounted within the C-shaped opening of the C-shaped frame 21, with the C-shaped opening of the C-shaped frame 21 facing downwards. The upper and lower rubber rollers 18 clamp the fiberglass cloth. During the conveying process, the fiberglass cloth drives the upper rubber roller 18... The upper rubber roller 18 and the lower rubber roller 19 move together to allow the fiberglass cloth to be conveyed forward smoothly. When the fiberglass cloth is offset along the axial direction of the upper rubber roller 18, it will be subjected to a large frictional force. This frictional force can prevent the fiberglass cloth from being offset by a large amount. Secondly, the two sets of tensioning mechanisms keep the fiberglass cloth in a taut state and convey it on the trimming platform 1, which facilitates the trimming operation. The lifting cylinder 20 drives the frame 17 to move up and down, which can adjust the distance between the upper rubber roller 18 and the lower rubber roller 19, which is convenient for the initial installation of the fiberglass cloth. At the same time, the distance between the upper rubber roller 18 and the lower rubber roller 19 can be adjusted according to the thickness of the fiberglass cloth.

[0023] Example 3

[0024] Based on Example 2, such as Figure 1 As shown, a lead screw groove 5 is provided on the trimming platform 1, and a bidirectional threaded lead screw 6 is rotatably installed in the lead screw groove 5. Lead screw sliders 7 are threadedly fitted onto the two threaded sections of the bidirectional threaded lead screw 6 with opposite threads. Two limiting plates 3 are respectively connected to the two lead screw sliders 7. A lead screw motor 8 is provided on one side of the trimming platform 1. The output shaft of the lead screw motor 8 is connected to the bidirectional threaded lead screw 6. The lead screw motor 8 drives the bidirectional threaded lead screw 6 to rotate, causing the two lead screw sliders 7 to move linearly along the axial direction of the bidirectional threaded lead screw 6. Since the threads of the two lead screw sliders 7 have opposite directions, their movement directions are opposite, thereby driving the two limiting plates 3 to move. The two limiting plates 3 can be adjusted to accommodate the conveying and trimming of fiberglass cloth of different widths by moving in opposite directions. The inner walls of both ends of the screw groove 5 are provided with through holes. The end of the screw slider 7 near the limiting plate 3 is connected to a drive rod 10. The drive rod 10 moves through the through hole and connects to the limiting plate 3. The drive rod 10 that drives the limiting plate 3 is hidden in the screw groove 5, so that there are no other protruding parts on the top surface of the trimming platform 1, so that the fiberglass cloth can contact the trimming platform 1 for conveying. The screw slider 7 drives the limiting plate 3 to move through the drive rod 10. The limiting plate 3 moves on the side of the trimming platform 1, and the middle part of the fiberglass cloth is supported by the trimming platform 1 for conveying.

[0025] Example 4

[0026] Based on Example 3, such as Figure 1 and Figure 2 As shown, a rectangular mounting groove 13 is provided on the inner side of the limiting plate 3. An offset detection plate 14 is installed in the rectangular mounting groove 13. A pressure sensor 15 is installed on the outer side of the limiting plate 3. The pressure shaft of the pressure sensor 15 moves into the rectangular mounting groove 13 and contacts the offset detection plate 14. Springs 16 are connected to both ends of the offset detection plate 14. The springs 16 are connected to the limiting plate 3. The winding device has a linear movement degree of freedom, and its movement direction is perpendicular to the conveying direction of the fiberglass cloth. This is prior art and will not be described in detail. When the fiberglass cloth is offset, the offset detection plate 14 in the offset direction will be squeezed by the fiberglass cloth. The offset detection plate 14 squeezes the corresponding pressure sensor 15, which increases the reading of the pressure sensor 15, thereby feeding back an offset signal. The position of the pressure sensor 15 based on the feedback signal determines the offset direction of the fiberglass cloth. The winding device responds to this signal by moving in the opposite direction of the offset and pulling the fiberglass cloth back to its original position, thereby adjusting the offset fiberglass cloth.
