Description

Technical Field

[0001] This utility model relates to the field of desizing machines, specifically a fabric feeding mechanism for a desizing machine. Background Technology

[0002] The fabric feeding mechanism of a desizing machine is a key component of the desizing equipment. Its main function is to stably and continuously transport the fabric during the desizing process, ensuring that the fabric receives the desizing treatment evenly and effectively. During desizing, a motor drives the transmission shaft to rotate, which in turn drives the feed rollers to rotate. After the fabric is fed into the feeding mechanism, it is tightly gripped by the feed rollers and transported to the desizing chamber. During the transport process, tension is used to ensure that the fabric is transported smoothly and continuously. At the same time, a guiding device ensures that the fabric is transported along a predetermined path, preventing the fabric from deviating from its direction. However, most existing desizing machine feeding mechanisms use a fixed tension method for fabric feeding, but this fixed tension method may affect the feeding effect of the feeding mechanism.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 In this embodiment of the present invention, a fabric feeding mechanism of a desizing machine includes a fabric feeding frame 1, a guide roller 3 is rotatably connected to one end of the inner side of the fabric feeding frame 1, and a first fabric feeding roller 4 is rotatably connected to the other end of the inner side of the fabric feeding frame 1. A connecting plate 2 is mounted above the guide roller 3, and a shaft 6 is provided between the first fabric feeding roller 4 and the guide roller 3. The two ends of the shaft 6 are respectively fixed to the two inner side walls of the fabric feeding frame 1.

[0022] Both ends of the outer wall of the shaft 6 are rotatably connected to the first connecting rod 61 via bearings. A first connecting rod 62 and a tension roller 63 are connected between the two first connecting rods 61. The first connecting rod 62 is fixedly connected to the middle of the two first connecting rods 61, and the tension roller 63 is rotatably connected to the lower end of the two first connecting rods 61. A tension adjustment component 7 is provided between the connecting plate 2 and the first connecting rod 62 to drive the tension roller 63 to revolve relative to the shaft 6 as the axis, so as to adjust the position and height of the tension roller 63.

[0023] The tension adjustment assembly 7 includes two guide rails 701 symmetrically distributed at both ends of the top of the fabric feeding frame 1. One end of each guide rail 701 is slidably connected to a first slide block 702, and the other end of each guide rail 701 is slidably connected to a second slide block 704. A crossbar 706 is connected between the two second slide blocks 704. A guide rod 703 is fixedly connected to one side wall of the first slide block 702. The end of the guide rod 703 away from the first slide block 702 passes through the outer wall of the second slide block 704 and the crossbar 706 and is fixedly connected to the limiting block 7010.

[0024] The tension adjustment assembly 7 also includes a second connecting rod 708 disposed between the two first slide blocks 702. The outer ends of the second connecting rod 708 are rotatably connected to the second connecting rod 709. The end of the second connecting rod 709 away from the second connecting rod 708 is rotatably connected to the outer wall of the first connecting rod 62. An electric telescopic rod 707 is installed on the connecting plate 2. The output end of the electric telescopic rod 707 is fixedly connected to the crossbar 706.

[0025] A spring 705 is sleeved on the outer wall of the guide rod 703, and the spring 705 is located between the first slide block 702 and the second slide block 704; the limiting block 7010 has a cylindrical structure, and the outer diameter of the limiting block 7010 is larger than the outer diameter of the guide rod 703; a second feeding roller 5 is provided above the first feeding roller 4, and the second feeding roller 5 is rotatably connected to the feeding frame 1 through a bearing, and a gap is left between the first feeding roller 4 and the second feeding roller 5 for the fabric to pass through; a first gear 41 is fixedly connected to one end of the first feeding roller 4, and a second gear 51 is provided at one end of the second feeding roller 5, the first gear 41 and the second gear 51 mesh with each other, and one end of the first feeding roller 4 is driven to rotate by a motor 42.

[0026] In this embodiment, the tension adjustment component 7 can be used to quickly adjust the position and height of the tension roller 63, thereby changing the distance between the tension roller 63 and the guide roller 3 and the first feed roller 4, and thus realizing the tension adjustment of the fabric. During the process of adjusting the position and height of the tension roller 63 using the tension adjustment component 7, the tension roller 63 can always remain in a horizontal state, and will not cause the tension roller 63 to be tilted, thus affecting the overall tension effect of the fabric. The tension adjustment component 7 is not only convenient and quick to adjust the tension, but also has the function of maintaining the tension balance of the fabric.

[0027] Specifically, the fabric is first passed over the guide roller 3, then under the tension roller 63, and finally passes between the first feed roller 4 and the second feed roller 5 into the desizing machine. The first feed roller 4 rotates under the drive of the motor 42. The rotating first feed roller 4 will drive the first gear 41 to rotate, and the first gear 41 will drive the second gear 51 to rotate, thereby forcing the second feed roller 5 to rotate in the opposite direction, thus forming a traction and feeding effect on the fabric.

[0028] During the fabric feeding process, the tension roller 63 presses down on the fabric to achieve tension. When it is necessary to adjust the tension, the electric telescopic rod 707 pushes the crossbar 706, which in turn pushes the second slide 704 to move along the length of the guide rail 701. The moving second slide 704 pushes the first slide 702 to move under the action of the guide rod 703 and the spring 705. The moving first slide 702 will adjust the position and height of the tension roller 63 through the second connecting rod 708 and the second connecting rod 709.

[0029] In addition, this solution provides a certain buffering force to the tension roller 63 through the spring 705, and the fabric provides an upward lifting force to the tension roller 63. At the same time, the spring compression provides the opposite force to 603, thereby maintaining the balance of the fabric and effectively ensuring the fabric conveying efficiency.

[0030] Compared to the existing tension adjustment method with both ends pressed down, this solution has the advantage of ensuring that the tension force is always consistent. When the tension roller 63 is subjected to force and moves, both ends of the tension roller 63 are always on the same horizontal line and will not tilt, thus ensuring uniform tension. In contrast, the existing tension roller with both ends pressed down may have one end tilted up, which will lead to uneven tension and affect the fabric conveying.

[0031] It should be noted that the horizontal position of the tension roller 63 in this scheme is lower than the position of the guide roller 3 and the first feed roller 4.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
