Description

Technical Field

[0001] This utility model relates to the field of glass fiber cloth edge cutting, specifically an automatic edge cutting and winding device for glass fiber cloth. Background Technology

[0002] Fiberglass cloth is mainly used in industry for heat insulation, fireproofing, and flame retardancy. When exposed to flame, this material absorbs a large amount of heat and prevents flames from passing through, thus isolating the air. The application of fiberglass cloth in daily life is becoming increasingly widespread. Currently, after fiberglass cloth is woven, long, excess edges are often exposed, requiring trimming. Most current trimming devices straighten the fiberglass cloth, then use a cutter to remove the edges, and finally manually roll up the cut cloth. Because trimming and rolling cannot be done simultaneously, it requires a significant amount of time for workers. Utility Model Content

Detailed Implementation

[0020] Example 1

[0021] like Figures 1 to 4 As shown, an automatic edge trimming and winding device for fiberglass cloth includes an edge trimming platform 1 and a winding mechanism disposed at one end of the edge trimming platform 1. Two sets of limiting components are disposed on the edge trimming platform 1, spaced apart along a direction perpendicular to the conveying direction of the fiberglass cloth. Each limiting component includes a strip-shaped C-shaped piece 2 and an edge trimming blade 3. A width limiting space for the fiberglass cloth is formed between the C-shaped openings of the two strip-shaped C-shaped pieces 2. An edge trimming motor 4 is mounted on the top of the strip-shaped C-shaped piece 2, and the output shaft of the edge trimming motor 4 is connected to the edge trimming blade 3. An edge trimming window 5 communicating with the C-shaped opening is opened on the top of the strip-shaped C-shaped piece 2. An avoidance groove 6 is opened on the inner bottom wall of the strip-shaped C-shaped piece 2, located directly below the edge trimming window 5. A portion of the edge trimming blade 3 passes through the edge trimming window 5 and enters the avoidance groove 6. The winding mechanism includes a base 7 and a winding frame 8. The winding frame 8 is slidably mounted on the base 7. The winding frame 8 is perpendicular to the conveying direction of the fiberglass cloth. A winding reel 9 is rotatably mounted on the winding frame 8. The fiberglass cloth is wound up by the rotation of the winding reel 9. The two sides of the fiberglass cloth pass through the C-shaped openings of the two strip C-shaped parts 2. The winding and conveying of the fiberglass cloth is limited by the two strip C-shaped parts 2 to prevent the fiberglass cloth from deviating and affecting the edge cutting effect. Guided by the strip C-shaped parts 2, the sides of the fiberglass cloth pass through the edge cutting blade 3. The edge cutting blade 3 is driven to rotate at high speed by the edge cutting motor 4. The edge cutting blade 3 cuts the fiberglass cloth, making the edge cut neater and the effect higher. Automatic edge cutting and winding are realized, improving the production efficiency of fiberglass cloth. The edge cutting accuracy is improved by the limit conveying method.

[0022] Furthermore, such as Figure 1 and Figure 4As shown, a push cylinder 21 is horizontally mounted on the base 7. The cylinder body of the push cylinder 21 is mounted on the base 7. The telescopic shaft of the push cylinder 21 is connected to the winding frame 8. When the fiberglass cloth is deviated during conveying, the push cylinder 21 drives the winding frame 8 to move in the direction of the deviation, making the winding of the fiberglass cloth more neat and improving the winding effect of the fiberglass cloth.

[0023] Example 2

[0024] Based on Example 1, such as Figures 1 to 3 As shown, the strip-shaped C-shaped component 2 is slidably mounted on the cutting platform 1. The strip-shaped C-shaped component 2 moves along a direction perpendicular to the conveying direction of the fiberglass cloth. Two screw grooves 10 are provided on the top surface of the cutting platform 1. A screw 11 is rotatably mounted within the screw grooves 10, and a screw slider 12 is threaded onto the screw 11. The two strip-shaped C-shaped components 2 are respectively fixed to the two screw sliders 12. Screw motors 13 are installed on both sides of the cutting platform 1. The output shaft of the screw motor 13 is connected to the screw 11. When the fiberglass cloth is conveyed off-center, the fiberglass cloth will squeeze the inner wall of the strip-shaped C-shaped component 2, causing wrinkles. This will affect the cutting... To ensure precise edge cutting, the C-shaped components 2 are designed to slide. When the fiberglass cloth shifts, the two C-shaped components 2 move in the direction of the shift, ensuring that the fiberglass cloth remains flat while being conveyed within the two C-shaped components 2, resulting in a better edge cutting effect. Specifically, the lead screw motor 13 drives the lead screw 11 to rotate, causing the lead screw slider 12 to move linearly along the axis of the lead screw 11. This causes the lead screw slider 12 to drive the C-shaped components 2 to move linearly along the axis of the lead screw 11, that is, to move the C-shaped components 2 in a direction perpendicular to the conveying direction of the fiberglass cloth, in order to accommodate the shift of the fiberglass cloth.

[0025] Example 3

[0026] Based on Example 2, such as Figure 1 and Figure 2As shown, a detection plate 17 is installed inside the C-shaped opening of the strip-shaped C-part 2. The side of the fiberglass cloth contacts the detection plate 17. A pressure sensor 18 is installed on the outer wall of the strip-shaped C-part 2. A circular hole 19 communicating with the C-shaped opening is opened on the side wall of the strip-shaped C-part 2. The pressure shaft of the pressure sensor 18 passes through the circular hole 19 and contacts the detection plate 17. Springs 20 are connected to both ends of the detection plate 17. The springs 20 are connected to the inner wall of the C-shaped opening and are in a stretched state. The detection plate 17 and the pressure sensor 18 cooperate to detect whether the fiberglass cloth has shifted, and control the screw motor 13 to start in time. Specifically, the side of the fiberglass cloth contacts the detection plate 17, and the springs 20 are connected to the inner wall of the C-shaped opening. The reaction force of 20 keeps the detection plate 17 in constant contact with the pressure axis of the pressure sensor 18. The force exerted by the detection plate 17 on the pressure sensor 18 is the initial pressure. When the fiberglass cloth shifts, it will squeeze the detection plate 17 in the direction of shift, making the pressure of the pressure sensor 18 corresponding to this detection plate 17 greater than the initial pressure, while the pressure of the other pressure sensor 18 remains basically unchanged. At this time, the fiberglass cloth shift signal is fed back. The position of the pressure sensor 18 with increased pressure is used to determine the shift of the fiberglass cloth, thereby controlling the screw motor 13 to rotate forward or backward to adapt to the shift of the fiberglass cloth, ensuring that the cutting position does not change and improving the cutting effect.

[0027] Example 4

[0028] Based on Example 3, such as Figure 2 As shown, a movable plate 14 is provided inside the C-shaped opening of the strip C-shaped component 2. The movable plate 14 has the freedom to move along the height direction of the strip C-shaped component 2. A clearance window 15 is provided through the movable plate 14 for the cutting blade 3 to pass through. Cylinders 16 are provided at both ends of the top of the strip C-shaped component 2. The telescopic shaft of the cylinder 16 is movably inserted into the C-shaped opening and connected to the movable plate 14. The cylinder 16 drives the movable plate 14 to move up and down, adjusting the distance between the movable plate 14 and the inner bottom wall of the strip C-shaped component 2 to accommodate glass fiber cloth of different thicknesses, so that the glass fiber cloth is transported flat and the cutting effect is improved.
