[0002] A fabric cutter is a mechanical device specifically designed for cutting fabrics, and it can be used to cut the fabric of sunshade curtains.

[0003] Chinese patent CN202323426544.8 discloses a textile cutting machine for preventing fabric deviation. It includes a base plate as a mounting carrier, an anti-deviation mechanism fixedly mounted on the top surface of the base plate, and a cleaning structure fixedly connected to the top surface of the base plate. The anti-deviation mechanism includes a concave plate fixed to the top surface of the base plate, a U-shaped block fixedly connected to the top surface of the concave plate, a telescopic rod fixedly connected to the bottom surface of the U-shaped block, and a concave block fixedly connected to the bottom surface of the telescopic rod. This invention, by providing a U-shaped block, telescopic rod, and U-shaped block on the surface of the concave plate, can limit the movement of the garment fabric during cutting, preventing deviation and improving performance. Furthermore, by tightening the limiting nut and sliding the concave block, the U-shaped block can be separated from the concave block, facilitating measurement of the garment fabric during cutting, depending on the type of U-shaped block. A measuring ruler is also provided on the surface of the base plate for convenient measurement of the garment fabric during cutting.

[0004] However, after the cutting of the aforementioned fabric cutting machine is completed, the operator needs to remove the cut fabric first, then pull the fabric to be cut to determine the size of the fabric to be cut, and finally the cutting blade cuts the fabric. However, when pulling the fabric, because the cutting blade is relatively close to the edge of the fabric, when the fabric needs to be pulled, the operator may come into contact with the cutting blade, resulting in injury to the operator. Therefore, a fabric cutting machine is proposed to solve the above problems. Utility Model Content

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1 like Figure 1-2As shown, the present invention proposes a fabric cutting machine, including a base 4 and a mounting plate 8. A cutting table 3 is mounted on the top of the base 4, and a cutting slot 2 is provided on the cutting table 3. Side plates 5 are provided on the top of the base 4 and on both sides of the cutting table 3. There are two mounting plates 8 arranged symmetrically, and the two symmetrical mounting plates 8 are connected by multiple connecting columns 21. A moving mechanism is provided between the two side plates 5, and the moving end of the moving mechanism is connected to one of the mounting plates 8. A driven component is installed between the two side plates 5 and between the two mounting plates 8, and a connecting gear 25 is also provided. One side of the connecting gear 25 is rotatably connected to one mounting plate 8, and the other side of the connecting gear 25 is connected to a rotating plate 15. A rotating component is mounted on one mounting plate 8, and the transmission end of the rotating component is connected to the connecting gear 25. A cutting component is installed on the side of the rotating plate 15 away from the rotating component. Protective shells 1 are installed on the top of the base 4 and on both sides of the cutting component.

[0024] It should be noted that the cutting table 3 is used to support the fabric to be cut, and its surface is polished to reduce friction between the fabric and the table. The cutting slot 2 is positioned to correspond to the position of the cutter 14 in the cutting assembly, and its slot size is slightly larger than that of the cutter 14 to ensure that the cutter 14 can cut the fabric smoothly.

[0025] Two symmetrically arranged mounting plates 8 are connected into a whole by multiple connecting posts 21, which are fixed to the mounting plates 8 by bolts.

[0026] The moving mechanism is connected to the mounting plate 8 to adjust the position of the cutting component. The driven component plays a guiding and limiting role during the movement of the mounting plate 8. Through the cooperation of the alignment wheel 12 and the square rod 6, it ensures that the mounting plate 8 can move smoothly along the preset trajectory during movement, avoiding deviation and improving the cutting accuracy. The connecting gear 25 is a key component for realizing the rotation of the rotating plate 15. It is fixedly connected to the rotating plate 15. When the rotating assembly drives the connecting gear 25 to rotate, the rotating plate 15 rotates synchronously.

[0027] Example 2 like Figure 2-3As shown, based on Embodiment 1, this embodiment further defines the moving mechanism, which includes a second motor 26, a moving block 9, a first threaded rod 10, and a connecting block 13. The second motor 26 is mounted on one side plate 5, and the first threaded rod 10 is rotatably connected between the two side plates 5. The output shaft of the second motor 26 passes through the side plate 5 connected to it and is coaxially connected to the end of the first threaded rod 10. The moving block 9 is threaded onto the outer end face of the first threaded rod 10, and the outer side of the moving block 9 is connected to the inner wall of one side mounting plate 8 through the connecting block 13. The driven component includes a connecting rod 11, a positioning wheel 12, and a square rod 6. There are four square rods 6, which are equidistantly installed between the two side plates 5. The connecting rods 11 are arranged in pairs, and the two pairs of connecting rods 11 are installed between the two side mounting plates 8 and are located on the upper and lower sides of the four square rods 6, respectively. The two sides of the outer end face of the connecting rod 11 are rotatably connected to the positioning wheel 12, which abuts against the square rod 6.

[0028] It should be noted that when the second motor 26 is started, the output shaft of the second motor 26 drives the first threaded rod 10 to rotate, the first threaded rod 10 drives the moving block 9 to move, and the moving block 9 drives the mounting plate 8 to move through the connecting block 13, thereby realizing the position adjustment of the mounting plate 8 and related components. When the mounting plate 8 moves, the alignment wheel 12 rolls on the square rod 6, which plays a role in alignment and guidance, ensuring the stability of the movement of the mounting plate 8.

[0029] Example 3 like Figure 4 As shown, based on Embodiment 1, this embodiment further defines the rotating assembly, which includes a concave frame 17, a lifting gear plate 23, a slide rod 22, a second threaded rod 24, and a drive assembly. The concave frame 17 is mounted on one side of the mounting plate 8 near the connecting gear 25. The slide rod 22 is vertically arranged and installed between the inner walls of the upper and lower sides of the concave frame 17. One end of the second threaded rod 24 is connected to the inner bottom wall of the concave frame 17, and the other end of the second threaded rod 24 passes through the upper end of the concave frame 17 and is connected to the drive assembly, which is mounted on the mounting plate 8. Both the slide rod 22 and the second threaded rod 24 pass through the lifting gear plate 23. The toothed plates 23 are slidably connected, the second threaded rod 24 is threadedly connected to the toothed plates 23, and multiple tooth blocks of the toothed plates 23 mesh with the connecting gear 25. The drive assembly includes a first gear 18, a second gear 19, and a first motor 20. The first motor 20 is mounted on the inner wall of a mounting plate 8 on one side. The output shaft of the first motor 20 passes through the mounting plate 8 connected to it and is coaxially connected to the second gear 19. The first gear 18 is coaxially connected to the upper end of the second threaded rod 24, and the second gear 19 meshes with the first gear 18. The slide rod 22 is parallel to the second threaded rod 24. Both the first gear 18 and the second gear 19 are cross-axis gears.

[0030] It should be noted that the slide rod 22 is vertically arranged and installed between the upper and lower inner walls of the concave frame 17. It plays a guiding role in the lifting and lowering movement of the lifting gear plate 23. The slide rod 22 and the lifting gear plate 23 are slidably connected. When the lifting gear plate 23 moves under the drive of the second threaded rod 24, the slide rod 22 can limit the movement direction of the lifting gear plate 23, prevent it from deviating, and ensure that the lifting gear plate 23 always moves stably along the vertical direction, thereby ensuring the accuracy of the meshing transmission with the connecting gear 25.

[0031] When the drive assembly drives the second threaded rod 24 to rotate, the rotational motion is converted into the vertical linear motion of the lifting toothed plate 23 by means of its threaded connection with the lifting toothed plate 23. The threaded connection has self-locking properties, which can make the lifting toothed plate 23 stably stay in the required position when it stops moving.

[0032] The first motor 20 is a servo motor. The output shaft of the first motor 20 is coaxially connected to the second gear 19. The second gear 19 meshes with the first gear 18, driving the first gear 18 and the second threaded rod 24 coaxially connected to it to rotate. The first gear 18 and the second gear 19 are cross-shaft gears, which perfectly match the installation position relationship between the output shaft of the first motor 20 and the second threaded rod 24. Multiple tooth blocks on the lifting tooth plate 23 mesh with the connecting gear 25. The tooth profile of the tooth blocks matches the tooth profile of the connecting gear 25. When the lifting tooth plate 23 is raised or lowered, it can stably drive the connecting gear 25 to rotate, thereby enabling the rotating plate 15 and the cutting assembly to rotate.

[0033] Example 4 like Figure 5 As shown, based on Embodiment 1, this embodiment further defines the cutting component, which includes a first electric push rod 7, a mounting frame 16, and a cutter 14. The mounting frame 16 is mounted on the rotating plate 15, and the first electric push rod 7 is mounted on the mounting frame 16. The telescopic shaft of the first electric push rod 7 passes through the mounting frame 16 connected to it and is connected to the cutter 14. The cutter 14 is located directly above the cutting slot 2.

[0034] It should be noted that the first electric push rod 7, as the power component of the cutting assembly, can control the lifting speed and displacement of the cutter 14. When the fabric needs to be cut, the telescopic shaft of the first electric push rod 7 extends, pushing the cutter 14 downward. After the cutting is completed, the telescopic shaft retracts, driving the cutter 14 to reset.

[0035] The cutter 14 is located directly above the cutting slot 2, ensuring that the cutter 14 can accurately extend into the cutting slot 2 when cutting downwards, which not only ensures that the fabric is completely cut, but also avoids the cutter 14 from contacting the cutting table 3 and causing damage to the blade or the table.

[0036] Working principle: In practical use, when it is necessary to pull the fabric, the first motor 20 is started. The output shaft of the first motor 20 drives the second gear 19 to rotate, the second gear 19 drives the first gear 18 to rotate, and the first gear 18 drives the second threaded rod 24 to rotate. Since the second threaded rod 24 is threadedly connected to the lifting toothed plate 23, and the slide rod 22 guides the lifting toothed plate 23, the lifting toothed plate 23 moves up and down under the rotation of the second threaded rod 24. The teeth of the lifting toothed plate 23 drive the connecting gear 25 to rotate, and the connecting gear 25 drives the rotating plate 15 to rotate, thereby causing the cutter 14 of the cutting component to rotate into the protective housing 1. After that, the worker can safely pull the fabric, preventing the worker from coming into contact with the blade of the cutter 14 when pulling the fabric. This physically isolates the worker from the risk of contact with the cutter 14 and effectively avoids the occurrence of personal injury.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
