Description

Technical Field

[0001] This utility model belongs to the technical field of fabric spreading machine accessories, and relates to a fabric spreading structure for a fabric spreading machine. Background Technology

[0002] In a fabric spreading machine, a spreading mechanism is usually set up to spread the fabric. The spreading mechanism generally includes an arc-shaped spreading rod that is high in the middle and low at both ends. When the fabric passes over the spreading rod, it is affected by the weight of the fabric, and the two ends of the fabric will slide down along the spreading rod, thereby spreading the fabric.

[0003] Chinese utility model patent CN205240913U (publication date: 2016.05.18) discloses an adjustable fabric spreading rod mechanism, including a frame and a fabric spreading rod installed on the frame. Rocker arms are symmetrically arranged on the top walls of the left and right sides of the frame. The fabric spreading rod is arc-shaped, and its two ends are mounted on the rocker arms via rotating shafts. The fabric spreading rod can rotate around the rocker arms via the rotating shafts and then be positioned. The advantage is that when the fabric spreading machine is spreading knitted fabric, adjusting the fabric spreading rod so that the arc-shaped rod faces upwards allows the fabric to spread out to both sides as it passes through the arc-shaped rod. When the fabric spreading machine is spreading woven fabric, adjusting the fabric spreading rod so that the straight rod faces upwards prevents the fabric from spreading out.

[0004] Different fabric specifications require different spreading rods. For example, thicker and coarser fabrics generally require a taller spreading rod structure to achieve a greater height difference with the conveyor plane in order to spread the fabric. However, the existing spreading structure does not allow for adjustment of the spreading rod height, thus it cannot adapt to different fabrics. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a fabric spreading structure for a fabric spreading machine, thereby improving the versatility of the fabric spreading machine and the quality of fabric spreading.

[0006] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution:

[0007] A fabric spreading structure for a fabric spreading machine includes a frame and a spreading mechanism connected to the inside of the frame. The spreading mechanism includes a spreading base, a spreading straight rod, and a spreading arc rod. The spreading bases are symmetrically arranged, and the spreading straight rod and the spreading arc rod are connected between the spreading bases. An adjusting plate extends outward from the spreading base. The adjusting plate is provided with a plurality of height adjusting holes. The ends of the spreading arc rods are selectively connected to the height adjusting holes. The spreading arc rods have different spreading heights when connected to different height adjusting holes.

[0008] In the fabric spreading structure of the above-mentioned fabric spreading machine, preferably, the fabric spreading base is a circular base, the adjusting plate extends outward in the radial direction, and the height adjusting holes are located in the same radial direction.

[0009] In the fabric spreading structure of the above-mentioned fabric spreading machine, preferably, the spreading rod is coaxially arranged and fixedly connected to the spreading base.

One end of the fabric spreading mechanism is fitted onto the rotating shaft and the other end abuts against the mounting base and is locked with screws. Preferably, the mounting base is provided with a limiting groove that cooperates with the fabric spreading mechanism.

[0012] In the fabric spreading structure of the above-mentioned fabric spreading machine, one end of the spreading straight rod is provided with a sliding rod extending out of the spreading base.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-6 :

[0024] A fabric spreading structure for a fabric spreading machine includes a frame 1 and a spreading mechanism connected to the inner side of the frame 1. The spreading mechanism includes a spreading base 2, a spreading straight rod 3, and a spreading arc rod 4. The spreading base 2 is symmetrically arranged, and the spreading straight rod 3 and the spreading arc rod 4 are connected between the spreading base 2. An adjusting plate 5 extends outward from the spreading base 2. The adjusting plate 5 is provided with a plurality of height adjusting holes 6. The end of the spreading arc rod 4 can be selectively connected to the height adjusting hole 6. The spreading arc rod 4 has different spreading heights when connected to different height adjusting holes 6.

[0025] When the spreading arc rod 4 is connected to different height adjustment holes 6 (when the connecting hole 7 is aligned with the height adjustment hole 6, and then connected with screws), the spreading arc rod 4 will have different spreading heights (the height of the spreading arc rod 4 to the conveying plane). When the fabric passes over the spreading arc rod 4, it is affected by its own weight, which pulls the fabric to extend to both ends, making the fabric flatter. The higher the spreading height, the greater the spreading force. According to different fabric characteristics (such as fabric type, thickness, roughness, etc.), the appropriate spreading height can be selected so that all fabrics can obtain a good spreading effect.

[0026] Preferably, the spreading base 2 is a circular base, the adjusting plate 5 extends outward in the radial direction, and the height adjusting holes 6 are located in the same radial direction.

[0027] Preferably, the spreading rod 3 is coaxially arranged and fixedly connected to the spreading base 2.

[0028] To ensure a more stable installation of the curved support rod 4 and prevent rotation due to its curved structure, the height adjustment holes 6 are spaced at the same interval. The end of the curved support rod 4 is provided with two or more connecting holes 7, each connecting hole 7 being fixedly connected to one height adjustment hole 6. Preferably, the spacing between the connecting holes 7 is the same as the spacing between the height adjustment holes 6. Preferably, the end of the curved support rod 4 is provided with two connecting holes 7, and the two connecting holes 7 are symmetrically arranged with respect to the end axis of the curved support rod 4.

[0029] This embodiment further provides a rotary switching structure for the spreading mechanism: a rotating shaft 8 is provided on one side of the frame 1, and a mounting base 9 is provided on the other side. The rotating shaft 8 is rotatably connected to the frame 1 and locked with screws (the rotating shaft 8 and the frame 1 have corresponding mounting holes). One end of the spreading mechanism is fitted onto the rotating shaft 8, and the other end abuts against the mounting base 9 and is locked with screws. Preferably, the mounting base 9 is provided with a limiting groove that cooperates with the spreading mechanism. Through the rotary switching structure, the spreading arc rod 4 and the spreading straight rod 3 can be switched: loosen the screws to unlock the rotating shaft 8, rotate the rotating shaft 8 by means of a tool or manually, and the spreading arc rod 4 connected to the adjusting plate 5 rotates to below the spreading straight rod 3. Then tighten the screws to relock the rotating shaft 8. At this time, the fabric passes through the spreading straight rod 3, and the spreading mechanism no longer has the spreading function.

[0030] This embodiment further provides a quick-assembly structure and an adjustment structure for the spreading mechanism: one end of the spreading rod 3 is provided with a slide rod 10 extending out of the spreading base 2. The slide rod 10 is coaxially arranged with the spreading rod 3 and slidably connected in the inner cavity of the spreading rod 3. A spring 11 is provided in the spreading rod 3 to drive the slide rod 10 to move outward. The end of the slide rod 10 abuts against and is fixedly connected to the mounting base 9.

[0031] Furthermore, a plug 12 is fixed inside the spreading rod 3, and the two ends of the spring 11 are respectively connected to the plug 12 and the spring 11 seat at the end of the slide rod 10.

[0032] During installation, pressing the slide rod 10 inward shortens the axial dimension of the spreading mechanism. One end of the slide rod 10 is fitted onto the rotating shaft 8, and the other end is aligned with the mounting base 9. Driven by the spring 11, the slide rod 10 springs outward until it contacts the mounting base 9, and then is locked with screws (the slide rod 10, mounting base 9, and frame 1 have corresponding mounting holes). This structure allows the axial length of the spreading mechanism to be adjusted within a small range, thus adapting to a wider range of fabric spreading machines.

[0033] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
