[0002] In the preparation process of chopped strand mat, glass fibers need to be spread on a base fabric coated with an adhesive layer. Subsequently, the glass fibers are pressed flat on the base fabric by roller pressing. When the glass fibers are laid on the base fabric, the existing laying device controls the continuous vibration of the equipment to continuously lay the glass fibers in the hopper onto the base fabric under the action of vibration. However, because it is difficult to control the thickness and uniformity of the glass fibers when controlling the movement and laying of the glass fibers by vibration, it is difficult to control the thickness and uniformity of the glass fibers. It is also necessary for the staff to assist in replenishing the material, which is difficult to meet the usage requirements. Utility Model Content

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0022] like Figure 1-6 As shown, a fabric assembly for chopped strand mat (CSTM) includes:

[0023] The feeding mechanism is used to place glass fibers and can transport the placed glass fibers out.

[0024] The transfer mechanism is used to receive the glass fibers conveyed from the feeding mechanism and transfer the received glass fibers to the base fabric 1.

[0025] The fabric distribution mechanism is used to receive the glass fibers conveyed by the transfer mechanism and simultaneously distribute the glass fibers onto the base fabric 1 by vibration.

[0026] Furthermore, the material feeding mechanism includes a hopper 2, which has an inlet and an outlet. The outlet of the hopper 2 has a rectangular cross-section. A scraper 3 is provided on one side of the lower end of the outlet of the hopper 2, and a vibration motor 4 is provided on the outer surface of the hopper 2.

[0027] The vibration motor 4 is a small model, which can make the hopper 2 vibrate, but the vibration intensity is limited and cannot cause serious damage to other parts. However, regular maintenance of each part is still required. Since the hopper 2 contains glass fiber, the vibration motor 4 drives the hopper 2 to vibrate, which can make the glass fiber in the hopper 2 continuously discharged from the lower end of the hopper 2. The material of the hopper 2 can be metal or plastic. When the hopper 2 is made of plastic, the hopper 2 is integrally molded, which can prevent the hopper 2 from falling apart.

[0028] The scraper 3 is made of rubber or plastic. The scraper 3 can keep the glass fibers that fall onto the conveyor belt 9 and are located between the two partitions 10 at a certain height. When the height is high, the scraper 3 can scrape out the excess glass fibers and let the scraped glass fibers enter the space between the two adjacent partitions 10, so that the glass fibers that can be accommodated and transported between the two partitions 10 are roughly the same, so as to ensure the uniformity of the subsequent fabric.

[0029] Furthermore, the transfer mechanism includes a mounting box 5 and support legs 6 for supporting the mounting box 5. The upper end of the mounting box 5 is provided with an opening, and the discharge port of the hopper 2 is aligned with the upper opening of the mounting box 5. The interior of the mounting box 5 is provided with two conveying rollers 7, and the outer surface of the mounting box 5 is provided with a motor 8 for driving the conveying rollers 7 to rotate. A conveyor belt 9 is installed on the two conveying rollers 7, and partitions 10 are evenly provided on the outer surface of the conveyor belt 9. When the partitions 10 pass through the scraper 3, they will contact the scraper 3 and bend the scraper 3.

[0030] Of the two conveyor rollers 7, one is the active conveyor roller 7 and the other is the passive conveyor roller 7. That is, the active conveyor roller 7 is connected to the motor 8. The conveyor roller 7 and the conveyor belt 9 can be driven by friction, or teeth can be set on the surface of the conveyor roller 7 and corresponding teeth can be set on the inner surface of the conveyor belt 9. Through the cooperation between the teeth, the conveyor belt 9 is driven to rotate in the mounting box 5.

[0031] When the conveyor belt 9 rotates inside the mounting box 5, the glass fibers located in the hopper 2 can quickly enter between the two partitions 10 on the conveyor belt 9 under the action of the vibrating motor 4. At the same time, as the conveyor belt 9 moves continuously, the partitions 10 can contact the scraper 3 and bend the scraper 3. During the bending process, the scraper 3 can push some of the glass fibers that are higher than the partitions 10 into the space between the next two partitions 10, so that the amount of glass fibers falling between the two adjacent partitions 10 is approximately the same, and the conveyor belt 9 transfers the glass fibers out.

[0032] Furthermore, the installation box 5 is equipped with a support plate 11 inside. The support plate 11 is used to support the conveyor belt 9 below the discharge port of the hopper 2. The support plate 11 is used to provide partial support for the upper part of the conveyor belt 9, so that when the partition 10 passes the scraper 3, the upper part of the conveyor belt 9 will not be dented due to the scraper 3, and the amount of glass fiber between the two partitions 10 is guaranteed to meet the standard.

[0033] Furthermore, the fabric feeding mechanism includes housings 12 disposed on both sides of the mounting box 5, a guide plate 13 disposed between the two housings 12, the guide plate 13 is inclined, a counterweight 18 is disposed at the lower end of the lower surface of the guide plate 13, the two ends of the guide plate 13 are respectively connected to the housings 12 by two elastic members 14, and the two elastic members 14 located at the same end of the guide plate 13 have different installation heights, wherein the tension of the upper elastic member 14 is greater than that of the lower elastic member 14, a stop bar 15 is disposed at one end of the guide plate 13, a turntable 16 is disposed at one end of the conveying roller 7, blades 17 are evenly disposed on the outer surface of the turntable 16, and a through groove is provided on the housing 12 for the blades 17 to pass through.

[0034] When the glass fiber on the conveyor belt 9 moves to the position of the guide plate 13, it will fall onto the guide plate 13 under the action of gravity. The glass fiber will slide down through the guide plate 13 and fall onto the base fabric 1 that passes through the mounting box 5.

[0035] The elastic element 14 is a spring or elastic rope. Since the tension of the upper elastic element 14 is greater than that of the lower elastic element 14, when the conveying roller 7 drives the turntable 16 and the blade 17 to rotate, the blade 17 continuously strikes the stop bar 15 on the guide plate 13, causing the guide plate 13 to vibrate continuously. At the same time, the vibration amplitude at the lower end of the guide plate 13 is greater than that at the upper end of the guide plate 13. That is, the jumping amplitude of the glass fiber at the upper end of the guide plate 13 is less than that at the lower end of the guide plate 13, so that the glass fiber can be evenly and dispersed on the base fabric 1. The counterweight 18 can keep the lower end of the counterweight 18 at a low position, preventing the glass fiber on the guide plate 13 from jumping obliquely upward due to vibration.

[0036] The base fabric 1 moves at a speed of 10 cm / s. By adjusting the movement parameters of the conveyor belt 9, the ability of the conveyor belt 9 to convey glass fiber is adapted to the movement speed of the base fabric 1, so as to ensure that the glass fiber can be evenly distributed on the base fabric 1.

[0037] Some glass fibers remaining on the conveyor belt 9 may fall directly onto the base fabric 1 below as the conveyor belt 9 moves. Since the base fabric 1 below the mounting box 5 is constantly moving, the fallen sporadic glass fibers will not affect the subsequent glass fiber fabric.

[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
