Description

Technical Field

[0001] This utility model relates to the field of textile industry technology, and in particular to an automatic feeding and conveying device for woven fabrics. Background Technology

[0002] In the modern textile and packaging industry, woven fabric is an important raw material, and its automated feeding and conveying efficiency directly affects production efficiency. Traditional woven fabric feeding equipment generally suffers from many problems. First, the unwinding process relies on manual intervention, and the fabric is prone to jamming due to adhesion and entanglement, resulting in low unwinding efficiency and the risk of fabric damage. Second, the guiding mechanism is mostly a fixed structure or manually adjustable, which is difficult to adapt to fabrics of different widths, and the calibration accuracy for fabric deviation is insufficient, which can easily lead to quality problems such as wrinkles and breaks. Third, it lacks integrated cleaning functions, and impurities on the fabric surface require additional processing, increasing production cycle and cost. In addition, the existing equipment has a low degree of automation, requiring manual monitoring throughout the process, resulting in high labor costs and difficulty in meeting the needs of large-scale continuous production. As the industry's requirements for production efficiency and product quality continue to increase, there is a need for a woven fabric feeding and conveying device that can achieve automatic and efficient unwinding, easy calibration, and simultaneous fabric cleaning, and has a high degree of versatility and automation, in order to overcome the limitations of traditional technology.

[0031] Reference Figure 1-4 This utility model discloses an automatic feeding and conveying device for woven fabric, comprising a base plate 1, a support rod 2 fixedly connected to the upper front surface of the base plate 1, a second bracket 25 fixedly connected to the upper rear surface of the base plate 1, a fixed frame 7 fixedly connected to the outer side of the second bracket 25, a first drive motor 8 fixedly connected to the outer side of the fixed frame 7, a first gear 10 fixedly connected to the output end of the first drive motor 8, a second gear 11 meshing with the outer surface of the first gear 10, a guide mechanism provided at the upper middle part of the base plate 1, a first fixed shaft 3 fixedly connected to both sides of the support rod 2, a feeding roller 4 rotatably connected to the outer surface of the first fixed shaft 3, a driven roller 13 fixedly connected to the rear end face of the second gear 11, and a drive roller 12 fixedly connected to the rear end face of the first gear 10.

[0032] The guiding mechanism includes a first bracket 5, a second drive motor 14, a positive and negative threaded rod 15, a guide rod 16, a moving block 17, a second fixed shaft 18, a guide roller 19, a mounting bracket 20, a horizontal tube 22, a three-way valve 23, a support plate 9, and a vertical tube 24. The upper end face of the base plate 1 is fixedly connected to the first bracket 5. One side of the first bracket 5 is fixedly connected to the second drive motor 14. The output end of the second drive motor 14 is fixedly connected to the positive and negative threaded rod 15. The outer surface of the positive and negative threaded rod 15 is threadedly connected to the moving block 17. There are two moving blocks 17, which are symmetrically distributed on the outside of the positive and negative threaded rod 15. The upper end face of one side of the moving block 17 is fixedly connected to the support plate 9. The outer side of the support plate 9 is fixedly connected to the second fixed shaft 18. The outer surface of the second fixed shaft 18 is rotatably connected to the guide roller 19.

[0033] The front end face of the movable block 17 is fixedly connected to the mounting frame 20. The inner wall of the mounting frame 20 is fixedly connected to the horizontal pipe 22. The outer surface of the horizontal pipe 22 is inclined upward with flat nozzles 21. There are multiple flat nozzles 21 and they are horizontally distributed. The lower end of the horizontal pipe 22 is connected to the vertical pipe 24. The lower end of the vertical pipe 24 is fixedly connected to the three-way valve 23. The upper end face of the base plate 1 is fixedly connected to the air pump 6. The front end of the air pump 6 is fixedly connected to the delivery pipe 26. The upper end of the delivery pipe 26 is fixedly connected to the lower end of the three-way valve 23.

[0034] Working principle: When the automatic feeding and conveying device for woven fabric is working, the woven fabric is rolled up and placed on the feeding roller 4. The feeding roller 4 is mounted on the support rod 2 through the first fixed shaft 3 on both sides and can rotate freely. The first drive motor 8 is started, and the first gear 10 at its output end drives the second gear 11 that meshes with it. The drive roller 12 and the driven roller 13 rotate in opposite directions, forming a clamping and conveying force, which pulls the feeding roller 4 to release the woven fabric and convey it forward.

[0035] The guide roller 19 at the front end of the feed roller 4, together with the flat nozzle 21 at the lower end, achieves efficient unwinding. The compressed air generated by the air pump 6 is transmitted to the transverse pipe 22 through the conveying pipe 26, the three-way valve 23, and the vertical pipe 24, and is finally ejected at high speed by the flat nozzle 21 that is inclined upward. The airflow acts on the unwinding position, reducing the friction between the layers of the woven fabric, thereby improving the unwinding efficiency. At the same time, the second drive motor 14 drives the positive and negative thread screws 15 to rotate.

[0036] Because the threads at both ends of the lead screw are opposite, the moving blocks 17 symmetrically distributed on the outside of the lead screw will move towards or away from each other along the lead screw axis. The guide rod 16 provides stable guidance for the moving blocks 17. The moving blocks 17 are connected to the guide rollers 19 through the support plate 9, thereby flexibly adjusting the distance between the two guide rollers 19. This facilitates manual calibration of the lateral position of the woven fabric and prevents it from deviating during conveying. The airflow direction forms a certain angle with the fabric conveying direction, which not only assists in unwinding but also avoids impacting the fabric and causing deviation. In coordination with the tension control of the guide rollers 19, it ensures the efficiency and stability of the feeding process.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
