Detailed Implementation

[0042] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0044] Example 1:

[0045] This embodiment provides a fabric cutting machine, including:

[0046] A base frame 1 is provided, and a workbench 2 is provided on the base frame 1. The workbench 2 is used to place the fabric to be cut.

[0047] The feeding mechanism is installed on the base frame 1 and is used to pull the fabric to be cut along the X-direction line into the worktable 2;

[0048] The clamping mechanism includes a clamping roller 3, a bearing seat 4, a drive motor 5, and two drive cylinders 6. One end of the clamping roller 3 is rotatably mounted on the bearing seat 4, and the other end is connected to the output end of the drive motor 5. Both the bearing seat 4 and the drive motor 5 are mounted on the base frame 1 and can move along the Z direction. The two drive cylinders 6 are used to control the movement of the bearing seat 4 and the drive motor 5 along the Z direction, respectively.

[0049] The traction mechanism is installed on the workbench 2 and is used to traction the fabric on the workbench 2 to move along the X direction.

[0050] A cutting mechanism is installed in the base frame 1 and can be moved along the Y and Z directions for cutting the fabric to be cut placed on the cutting workbench 2.

[0051] The pressing mechanism is installed on the end of the base frame 1 away from the feeding mechanism and is used to press the end of the fabric to be cut.

[0052] Furthermore, the traction mechanism includes:

[0053] Traction roller 7 is rotatably mounted on worktable 2;

[0054] Rotary motor 8, mounted on base frame 1, is used to control the rotation of traction roller 7;

[0055] The output end of the rotary motor 8 is connected to the traction roller 7 via the transmission gear set 9.

[0056] In this technical solution, when the fabric cutting machine is working, the feeding mechanism first pulls the unwound fabric along the thread. The fabric is fed into the worktable 2 through the feeding mechanism. After a certain length of fabric has moved under the cutting mechanism, the unwound fabric stops, the pressing mechanism presses the end of the fabric onto the worktable 2, and the clamping mechanism fixes the fabric on the worktable 2. Then, the cutting mechanism moves along the Z and X directions to cut the fabric, completing the fabric cutting operation. Then the fabric continues to be unwound, and the traction mechanism pulls the cut end of the fabric along the thread for further movement. After the fabric has moved a certain length, the clamping mechanism fixes the fabric again, and the cutting mechanism performs the cutting operation. This cycle repeats.

[0057] Specifically, the traction roller 7 is installed inside the worktable 2, and the clamping roller 3 is installed on the base frame 1 and is positioned opposite to the clamping roller 3. The two drive cylinders 6 control the drive motor 5 and the bearing seat 4 to move along the Z direction, thereby driving the clamping roller 3 to move closer to or away from the traction roller 7 along the Z direction. When the clamping roller 3 moves closer to the traction roller 7, the fabric will be clamped on the worktable 2 by the traction roller 7 and the clamping roller 3 to achieve fixation, thereby preventing the fabric from shifting during the cutting mechanism and preventing the length of the cut fabric from being affected.

[0058] After the cutting is completed, the cut fabric from workbench 2 is manually collected and stored. Then, the fabric continues to be unwound. At this time, drive motor 5 controls the rotation of clamping roller 3, while rotary motor 8 controls the movement of transmission gear set 9, which in turn drives traction roller 7. While clamping the fabric, traction roller 7 and clamping roller 3 rotate in opposite directions, providing traction and driving the cut end of the fabric to move further along the stitching, facilitating subsequent fabric cutting operations.

[0059] After the fabric has moved a certain distance again, the traction roller 7 and the clamping roller 3 stop rotating, and the cutting mechanism starts working again to cut the fabric. Then the traction roller 7 and the clamping roller 3 rotate again to pull the fabric to move, and so on.

[0060] In summary, by using a pressing mechanism to hold down the ends of the fabric, and clamping rollers 3 and traction rollers 7 to hold the fabric on the worktable 2, the fabric is automatically fixed, which helps to accurately cut the fabric, improves the cutting quality, and eliminates the need for manual fabric fixing, effectively reducing the safety risks during the cutting process. Furthermore, after the fabric is cut, the clamping rollers 3 and traction rollers 7 rotate synchronously in opposite directions to traction the remaining fabric, facilitating the automatic cutting of the remaining fabric and demonstrating high practicality.

[0061] Example 2:

[0062] This embodiment provides a fabric cutting machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0063] Furthermore, the feeding mechanism includes:

[0064] Two feeding rollers 10, both of which are rotatably mounted on the base frame 1, are used to pull the fabric to be cut along the X-direction guide line into the worktable 2.

[0065] Two drive units 11 are mounted on the base frame 1 and are used to control the rotation of the corresponding feed rollers 10.

[0066] In this technical solution, the two drive units 11 can be motors, and each drive unit 11 independently controls the rotation of one feed roller 10, with the gap between the two feed rollers 10 just large enough for the fabric to pass through. Through this structural design, when the two feed rollers 10 rotate, they will generate friction with the fabric, using the friction to pull the fabric threads.

[0067] Example 3:

[0068] This embodiment provides a fabric cutting machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0069] Furthermore, the cutting mechanism includes:

[0070] Fixing base 12, which is movable along the Y direction and installed in the base frame 1;

[0071] Translation component, mounted on base frame 1, is used to control the movement of fixed base 12 along the Y direction;

[0072] The cutting blade 13 is movably mounted on the fixed base 12 along the Z direction;

[0073] The lifting assembly is mounted on the fixed base 12 and is used to control the movement of the cutting blade 13 along the Z direction.

[0074] In this technical solution, when the cutting mechanism is working, the translation component first controls the fixed seat 12 to move along the Y direction, so that the cutting blade 13 is located on one side of the worktable 2 along the Y direction. Then, the lifting component controls the cutting blade 13 to descend along the Z direction, so that the cutting end of the cutting blade 13 comes into contact with the fabric. Then, the translation component controls the fixed seat 12 to move along the Y direction, driving the cutting blade 13 to move. The cutting blade 13 cuts the fabric along the Y direction, thereby achieving the cutting of the fabric.

[0075] Furthermore, the translation components include:

[0076] The lead screw 14 is rotatably mounted on the base frame 1 and threadedly connected to the fixed seat 12;

[0077] Guide rod 15 is installed on base frame 1 and passes through fixed seat 12 along Y direction;

[0078] The control motor 16 is mounted on the base frame 1 and is used to control the rotation of the transmission screw 14.

[0079] Through this structural design, the control motor 16 drives the lead screw 14 to rotate, and with the guidance of the guide rod 15, the cutting blade 13 can move stably along the Y direction, thereby achieving precise cutting of the fabric.

[0080] Furthermore, the lifting assembly includes:

[0081] Lifting cylinder 17 is mounted on fixed base 12;

[0082] The slide bar 18 has one end connected to the cutting blade 13 and the other end passing through the fixing base 12.

[0083] The cutting blade 13 is mounted on the output end of the lifting cylinder 17.

[0084] Through this structural design, the cutting blade 13 is driven to rise and fall by the lifting cylinder 17, and with the guidance of the slide bar 18, the cutting blade 13 can move quickly and stably along the Z direction. This allows the cutting blade 13 to rise quickly after completing the cutting work and to fall quickly when cutting work is needed, reducing downtime and effectively improving production efficiency.

[0085] Example 4:

[0086] This embodiment provides a fabric cutting machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0087] Furthermore, the pressing mechanism includes:

[0088] Pressure plate 19 is movable along the Z direction and is mounted on the base frame 1, and is located at the end of the base frame 1 away from the feeding mechanism;

[0089] The pressure cylinder 20 is mounted on the base frame 1 and is used to drive the pressure plate 19 to move along the Z direction.

[0090] In this technical solution, after a certain length of fabric moves through the cutting mechanism, the clamping roller and traction roller 7 clamp and fix the fabric, while the pressing cylinder 20 drives the pressure plate 19 to move down and press down the end of the fabric, which further fixes the fabric, improves the stability of the fabric during cutting, and avoids fabric deviation that could lead to incorrect cutting dimensions.
