DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1

[0029] Reference Figure 1-Figure 4 A cutting mechanism with high flatness, used in the field of fabric processing, comprises: a workbench 1, which serves as a basic support platform, with a support frame 2 firmly mounted on its top. On the top of the support frame 2, an electric push rod 3 is installed in a through-fixed manner, and the output end of the electric push rod 3 passes through the bottom of the support frame 2 and is fixedly connected to the mounting base 4. A cutter 16 is fixedly mounted at the bottom of the mounting base 4 for cutting operations. In order to cooperate with the operation of the cutter 16, a rectangular hole 13 is opened on the top of the workbench 1 to ensure that the cutter 16 can pass through smoothly and cut the fabric.

[0030] Two support bases 6 are provided on the top of the workbench 1. The two support bases 6 are located on both sides of the support frame 2 and are used to support the support rod 7 during the fabric conveying process. The fabric to be cut is wound around the support rod 7 to ensure that the fabric is in a stable state before cutting.

[0031] In order to enhance the stability of the mounting seat 4 during the up and down movement, two guide rods 15 are fixedly installed on the top of the mounting seat 4. The two guide rods 15 pass through the support frame 2 and are slidably connected to the support frame 2, thereby achieving a guiding effect on the mounting seat 4 and ensuring its stability during the lifting process.

[0032] To improve the flatness of the fabric during the cutting process, a finishing mechanism is provided. This finishing mechanism comprises two first sliding rods 17, which are slidably mounted on the top of the mounting base 4 and fixedly connected to a first pressing plate 19 at their bottoms. Furthermore, two second sliding rods 20 are slidably mounted on the top of the mounting base 4 and fixedly connected to a second pressing plate 22 at their bottoms. These two pressing plates work together to press and finish the fabric.

[0033] To ensure the pressing plates exert sufficient pressure on the fabric, first and second springs 18 and 21 are respectively sheathed around the outer walls of the first and second sliding rods 17 and 20. The ends of the first spring 18 are fixedly connected to the adjacent sides of the mounting base 4 and first pressing plate 19, while the ends of the second spring 21 are fixedly connected to the adjacent sides of the mounting base 4 and second pressing plate 22. This way, when the pressing plates contact the fabric, the spring force pushes them against the fabric, improving its smoothness.

[0034] In addition, one side of the mounting base 4 includes two rectangular openings 23, into which second connecting rods 24 are rotatably mounted. A rotational shaft 25 is rotatably provided through one side of each of the second connecting rods 24. Multiple second pressing rollers 26 are fixedly mounted on the outer walls of the rotational shafts 25. These second pressing rollers 26 cooperate with the first pressing plate 19 to smooth the fabric lengthwise as the cutter 16 descends, further improving its flatness.

[0035] Example 2

[0036] refer to Figure 1-Figure 4 , improved on the basis of Example 1: In order to ensure that the first pressing plate 19 and the second pressing plate 22 can press the fabric in sequence, the height of the second sliding rod 20 is set to be lower than the first sliding rod 17, thereby realizing the pressing order of the first pressing plate 19 first and then the second pressing plate 22.

[0037] Two mounting cavities 27 are defined at the bottom of each of the second and first pressure plates 22 and 19, each housing two pivoting rods 29 rotatably mounted within them. A third pressure roller 30 is pivotally mounted between the two pivoting rods 29, providing widthwise alignment of the fabric. The mounting cavities 27 also define two arcuate slots 28, within which the pivoting rods 29 pivot. When the third pressure roller 30 moves away from the fabric, the pivoting rods 29 rotate under the weight of the rollers 30, causing one end of the pivoting rods 29 to contact the mounting cavities 27, effectively limiting the position of the pivoting rods 29.

[0038] In order to guide the fabric, a connecting frame 8 is set on the workbench 1. A plurality of fans 9 are fixed in the connecting frame 8, and the air outlet of the fans 9 is directed towards the support frame 2, which can guide the conveying direction of the fabric and facilitate the operator to grab the fabric.

[0039] Finally, two rotating seats 10 are fixedly mounted on the top of the support frame 2. A common connecting shaft 12 is rotatably mounted between the two rotating seats 10. Two first connecting rods 11 are rotatably mounted on the outer wall of the connecting shaft 12. A first pressing roller 5 is rotatably mounted between the two first connecting rods 11. The first pressing roller 5 is used to press the fabric wrapped around the support rod 7, ensuring its stability during transport.

[0040] In the present application, when in use, the support rod 7 with the fabric wrapped around it is placed on the two support seats 6, and then the first connecting rod 11 is pulled downward to drive the first pressing roller 5 to press on the fabric to prevent the support rod 7 from rotating without external force. Then, one end of the fabric is manually pulled to move until it moves to a suitable degree, and multiple fans 9 are started at the same time. During the start-up process of the fans 9, the fabric will float to one side and be automatically leveled.

[0041] Then the electric push rod 3 is started to extend. During the extension of the electric push rod 3, the mounting seat 4 can be driven to move downward. The downward movement of the mounting seat 4 can drive the first pressing plate 19 to move downward through the first spring 18 and the first sliding rod 17. During the downward movement, the fabric can be driven downward by the two third pressing rollers 30. When the fabric contacts the workbench 1, it continues to move downward and can drive the rotating rod 29 to rotate outward through the third pressing roller 30. The fabric can be adjusted again by the friction between the third pressing roller 30 and the fabric, and at the same time, the second pressing roller 26 can be driven to contact the fabric and adjust the length direction of the fabric. It continues to move downward and can compress the first spring 18 through the mounting seat 4. At the same time, it drives the two third pressing rollers 30 under the second pressing plate 22 to adjust the width of the fabric again.

[0042] After finishing, the electric push rod 3 is started again to extend and drive the cutter 16 to move downward. During the downward movement of the cutter 16, the fabric can be cut in cooperation with the rectangular hole 13.

[0043] However, as is well known to those skilled in the art, the working principle and wiring method of the electric push rod 3 are commonplace, and are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selection according to their needs or convenience.

[0044] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
