[0004] In the prior art, including the aforementioned patent, due to the certain extensibility of synthetic fiber fabrics, although the entire synthetic fiber fabric production and conveying process is kept taut through the cooperation of multiple conveying rollers and tensioning rollers, when the cutting blade presses down on the synthetic fiber fabric, due to its extensibility, the fabric will be concave as the blade applies pressure and then be cut. Although the aforementioned patent can reduce the indentation on the fabric caused by the blade pressure, there is still room for optimization to further reduce the impact of indentation on the synthetic fiber fabric. A good solution is expected. Utility Model Content

[0026] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1-4 As shown, a fabric cutting mechanism for producing synthetic fiber fabric includes a cutting blade 1 that is driven to move downward in a vertical direction and a lifting part 2 located directly below the cutting blade 1 and driven to push the fabric being conveyed.

[0028] The lifting part 2 is provided with a knife receiving groove 21, and the cutting blade 1 is coaxial with the center of the knife receiving groove 21.

[0029] Specifically, the cutting mechanism provided in the above embodiment is located in the entire fabric production device. The device includes a frame, and a first guide roller 100 and a winding roller 200 symmetrically distributed in the vertical direction and rotatably mounted on the frame. The cutting blade 1 is located between the first guide roller 100 and the winding roller 200 and is distributed close to the winding roller 200.

[0030] Furthermore, the winding roller 200 is driven by a drive motor to rotate, thereby winding up the fabric. The above is existing technology and will not be elaborated further.

[0031] Furthermore, the cutting blade 1 is driven by the second extension unit 6 fixedly mounted on the frame, and the second extension unit 6 can include any driving method known in the art, such as a hydraulic extension rod, an electric extension rod, or a pneumatic extension rod.

[0032] Secondly, the lifting part 2 mentioned above can extend vertically and move upward to lift the fabric. The driving unit that realizes the above action can be a stepping linear module, a hydraulic telescopic rod, an electric telescopic rod, or a pneumatic telescopic rod; or it can rotate to lift. The driving unit that realizes the above action can be a motor direct drive or a motor-driven linkage assembly.

[0033] In the above technology, when the fabric is cut, the device stops conveying. At this time, the lifting part 2 is raised to lift the fabric to a predetermined height. Then, the cutting blade 1 moves down to cut the fabric. The lifting part 2 smooths the fabric in the cutting area. The entire cutting pressure is restricted by the blade groove 21, thereby reducing the pulling of the cutting blade 1 and increasing the area of ​​the indentation caused by the cutting pressure.

[0034] It should be noted that after the fabric has been wound a predetermined number of turns, a Hall sensor detects this. Once the predetermined number of turns is reached, the lifting unit 2 is activated to move upwards. When the lifting unit 2 reaches the predetermined position, it is detected by an infrared sensor or triggered by a switch. At this time, the cutting blade 1 moves downwards to cut. When the cutting blade 1 moves down to the predetermined position and is detected by an infrared sensor or triggered by a switch, it returns to its original position. After the operator replaces the winding roller 200, the winding roller 200 is restarted. The above control program and electronic components are common knowledge to those skilled in the art, and therefore will not be described in detail.

[0035] As a further embodiment of the present invention, the above embodiment also includes a circular column 3 and a first top extension unit 4. One end of the lifting part 2 is rotatably disposed at the end of the circular column 3, while the other end is rotatably disposed with a connecting rod 5 between it and the output shaft of the first top extension unit 4.

[0036] Specifically, the first extension unit 4 in the above embodiments can include any driving method known in the art, such as a hydraulic telescopic rod, an electric telescopic rod, or a pneumatic telescopic rod. The first extension unit 4 is fixedly installed on the frame, and deflection is achieved by extending the rod using the first extension unit 4.

[0037] As another embodiment of the present invention, the lifting part 2 is provided with a waist groove with both ends distributed in the vertical direction, and the rotating shaft of the circular column 3 is located in the waist groove.

[0038] Specifically, in this embodiment, the lifting part 2 can remain deflected or move along the waist groove direction. That is, when the first extension unit 4 extends, driving the lifting part 2 from... Figure 1 Switch to Figure 2 When the fabric is lifted, the lifting part 2 moves upward, thereby raising the fabric to a predetermined height.

[0039] As another embodiment of the present utility model, a rotating part 31 is rotatably provided on the circular column 3, and a protrusion 312 is fixedly provided on the outer side of the upper end surface of the rotating part 31.

[0040] The upper surface of the rotating part 31 is an inclined surface, and the high position of the inclined surface is located at the center of the protrusion 312. During the rotation stroke of the rotating part 31, it slides with the bottom surface of the lifting part 2 to push it up to a predetermined height.

[0041] Specifically, in the embodiment, when the first extension unit 4 extends, it drives the lifting part 2 from... Figure 1 Switch to Figure 2At this time, by driving the rotating part 31 to rotate, the protrusion 312 rotates toward the lifting part 2. During the rotation, it is tangent to the bottom surface of the lifting part 2, thereby raising it, that is, raising the lifting part 2 to lift the fabric to a predetermined height.

[0042] As another embodiment of the present invention, the outer wall of the circular column 3 is provided with a groove 32, and the rod 311 fixedly provided on the inner wall of the rotating part 31 extends from the groove 32 into the interior of the circular column 3.

[0043] A vertical rod 33 coaxial with the circular column 3 is welded onto the rod body 311, and a guide post 34 with sliding fit is inserted into the vertical rod 33.

[0044] The guide post 34 and the rotating shaft are connected by a trapezoidal gear 7 that is fixed to each other.

[0045] Specifically, the cross-section of the rotating shaft is rectangular, so it can rotate along with the lifting part 2. Furthermore, the cross-sections of the vertical rod 33 and the guide post 34 are rectangular. Therefore, the vertical rod 33 and the guide post 34 not only maintain a sliding fit but also rotate synchronously in the circumferential direction. Therefore, when the first extension unit 4 extends, driving the lifting part 2 from... Figure 1 Switch to Figure 2 When the lifting part 2 deflects, the two trapezoidal gears 7 mesh during the process, and the guide post 34 moves with the rotation of the shaft. At this time, the drive rotating part 31 rotates, so that the protrusion 312 rotates toward the lifting part 2. During the rotation, it is tangent to the bottom surface of the lifting part 2, thereby raising it, that is, raising the lifting part 2 to lift the fabric to a predetermined height.

[0046] It should be noted that a vertical plate is welded inside the circular column 3, and the guide column 34 is mounted on the vertical plate through a bearing. The vertical plate limits the guide column 34 so that the two trapezoidal gears 7 are always in a meshing state.

[0047] As another embodiment of the present invention, a bullseye ball bearing is fixedly installed at the bottom of the lifting part 2, and the bullseye ball bearing is in rolling connection with the rotating part 31.

[0048] Specifically, in the embodiment, bullseye balls can be added to convert the sliding friction between the protrusion 312 and the bottom of the lifting part 2 into rolling, thereby reducing the wear caused by sliding.

[0049] It should be noted that the aforementioned fixed installations and connections can be made using known connection methods such as welding, bolting, and snap-fitting; while rotating and hinged connections are installed using rotary bearings, and sliding connections are installed using sliding bearings. These installation methods are all common knowledge to those skilled in the art, and can be directly determined from the structural features; therefore, they will not be described in detail.

[0050] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
