Description

Technical Field

[0001] This utility model belongs to the field of fabric processing technology, and in particular relates to an automatic fixed-length cutting mechanism for a fabric cutting machine. Background Technology

[0002] In the textile production process, precise cutting of fabric according to the specifications of the textiles being produced is a crucial step in reducing fabric waste and improving production efficiency. Fabric cutting machines, as specialized equipment for fabric cutting in industries such as clothing, textiles, and leather, play a vital role in this process. The cutting mechanism, as the core component of the fabric cutting machine, directly undertakes the task of fabric cutting. However, in practical applications, the cutting mechanism of the fabric cutting machine has revealed the following significant shortcomings:

[0003] 1. Heavy workload of manual operation: Currently, when using the cutting mechanism of a fabric cutter to cut fabric, the cutting personnel need to manually pull the fabric to unwind it until the unwound size reaches the required cutting specifications, and then use the fabric cutter body on the cutting machine guide rail to complete the cutting. This operation method greatly increases the amount of manual operation for the cutting personnel, resulting in a significant increase in the workload.

[0004] 2. Low cutting accuracy and automation: During the manual unwinding of fabric, it is difficult to automatically stop the unwinding process, often requiring manual intervention to terminate the unwinding operation. This not only easily leads to untimely stopping of the unwinding, resulting in excessive unwinding and reduced fabric cutting accuracy, but also makes the entire cutting process overly reliant on manual labor, severely restricting the automation level of the fabric cutting machine.

[0005] To address these issues, we provide an automatic fixed-length cutting mechanism for fabric cutting machines. Utility Model Content

[0006] The purpose of this utility model is to provide an automatic fixed-length cutting mechanism for a fabric cutting machine. By setting up a fabric feeding component, the fabric can be automatically fed out, reducing manual labor. Furthermore, by setting up an automatic fixed-length component, the length of the fabric to be cut can be automatically determined, reducing manual intervention and enhancing automation, thereby solving the technical problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to an automatic fixed-length cutting mechanism for a fabric cutting machine, comprising a fabric cutting machine worktable, a fabric feeding assembly on the worktable, the fabric feeding assembly including a cutting machine guide rail and a fixed clamping plate on the worktable, a fabric cutting machine body on the cutting machine guide rail, a cylinder mounted on the inner top of a mounting bracket fixed to the upper surface of the fixed clamping plate, a movable clamping plate connected to the lower end of the piston rod at the telescopic end of the cylinder, movable frames fixed to one side wall of both the cutting machine guide rail and the fixed clamping plate, a bidirectional lead screw commonly arranged between the two movable frames, a motor mounted at the corner of the lower surface of the fabric cutting machine worktable, the output end of the motor connected to the end of the bidirectional lead screw; an automatic fixed-length assembly on the side wall of the fabric cutting machine worktable, the automatic fixed-length assembly including a scale on the side wall of the worktable, a switch mounted on the side wall of a mounting base on the scale, and a pointing block fixed to the side wall of the mounting base located below the switch.

[0009] The present invention is further configured such that the lower surface of the workbench of the fabric cutting machine has symmetrically opened sliding grooves, the movable frame has a U-shaped structure, and the inner bottom of the movable frame has a fixed slider, which is slidably connected inside the sliding groove.

[0010] The present invention is further configured such that a movable frame is fixedly connected to the other side wall of the cutting machine guide rail and the fixed clamping plate. The movable frame has a U-shaped structure and a guide block is fixedly connected to the bottom of the movable frame. The guide block is slidably connected to the inside of a groove opened on the lower surface of the fabric cutting machine workbench.

[0011] The present invention is further configured such that a guide rod, which is provided through the two movable frames, is located below the worktable of the fabric cutting machine, and ear seats symmetrically sleeved at both ends of the guide rod are connected to the lower surface of the worktable of the fabric cutting machine.

[0012] The present invention is further configured such that the mounting bracket is an inverted U-shaped structure, the two inner side walls of the mounting bracket have symmetrically opened guide grooves, the two side walls of the movable clamp have symmetrically fixed protrusions, and the protrusions are slidably connected inside the guide grooves.

[0013] The present invention is further configured such that the side wall of the fabric cutting machine workbench has symmetrically fixed supports, the supports are L-shaped structures, the side wall of the supports has threaded screws, and the scale is mounted on the supports.

[0014] The present invention is further configured such that the upper surface of the scale has a guide rail, the lower surface of the mounting base has a fixed lug, the lug is slidably connected inside the guide rail, and the bolt threaded on the upper surface of the mounting base passes through the lug.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting up a fabric unloading assembly, places the free end of the fabric on a fixed clamping plate. When the cylinder is opened, the piston rod at the cylinder's telescopic end extends downwards, causing the movable clamping plate to move downwards until the movable and fixed clamping plates secure the free end of the fabric. The motor is then energized, causing the bidirectional lead screw to rotate forward, while the cutting machine guide rail and fixed clamping plate move in opposite directions, unwinding the fabric until the unwound fabric meets the desired cutting length. This achieves automatic fabric unwinding, reducing manual labor. The fabric is then cut using the fabric cutting machine body on the cutting machine guide rail. The cut fabric is removed from the cutting machine's worktable. The motor is then energized again, causing the bidirectional lead screw to rotate in the reverse direction, and the cutting machine guide rail and fixed clamping plate move in opposite directions until the distance between them is adjusted to the minimum value, facilitating further fabric cutting.

[0017] 2. This utility model features an automatic length-fixing component. By loosening the bolts clockwise, the mounting base is released from its fixed position. The mounting base is then pushed, and the lugs slide along the guide rail, causing the mounting base to move accordingly. This adjusts the positions of the switch and the pointing block until the scale indicated by the pointing block is half the required fabric size. The bolts are then tightened counterclockwise to fix the switch position. When the movable frame presses the switch during the movement, the motor is de-energized, stopping the fabric unwinding and automatically determining the required fabric size. This reduces manual intervention and increases the accuracy of fabric cutting. Attached Figure Description

Example 1

[0026] Please see Figure 1 This utility model is an automatic fixed-length cutting mechanism for a fabric cutting machine, including a fabric cutting machine workbench 1, a bracket 302 and a screw 302a. The bracket 302 is used to support the scale 301, and the screw 302a is used to fix the position of the scale 301 on the bracket 302 to increase the stability of the scale 301.

[0027] Specifically, there are symmetrically fixed brackets 302 on the side wall of the fabric cutting machine workbench 1, and there are threaded screws 302a on the vertical section side wall of the brackets 302.

[0028] Furthermore, the support 302 has an L-shaped structure;

[0029] The operation process of this embodiment is as follows: place the scale 301 on the bracket 302, turn the screw 302a counterclockwise until the screw 302a presses against the scale 301 to fix the position of the scale 301; loosen the screw 302a clockwise to release the fixation of the position of the scale 301, and remove the scale 301 from the bracket 302. Example 2

[0030] Please see Figure 1 , Figure 2 and Figure 3Based on the first specific embodiment, a fabric feeding assembly 2 is provided. The fabric feeding assembly 2 includes a cutting machine guide rail 201, a movable frame 202, a slider 202a, a moving frame 203, a guide block 203a, a fixed clamping plate 204, a mounting frame 204a, a cylinder 204b, a movable clamping plate 204c, a protrusion 204d, a motor 205, a two-way lead screw 205a, and a guide rod 206. When the piston rod of the telescopic end of the cylinder 204b extends, the movable clamping plate 204c moves downward toward the fixed clamping plate 204, clamping the fabric on the fixed clamping plate 204. When the motor 205 is energized, the two-way lead screw 205a adjusts the distance between the cutting machine guide rail 201 and the fixed clamping plate 204 according to the required cutting fabric size, automatically unwinding the fabric and reducing manual labor.

[0031] Specifically, the cutting machine guide rail 201 and the fixed clamping plate 204 are both set on the upper surface of the fabric cutting machine workbench 1. The fabric cutting machine body (which is consistent with the cutting machine disclosed in existing fabric cutting machines) is set on the cutting machine guide rail 201. There is a movable frame 202 fixedly connected to one side wall of both the cutting machine guide rail 201 and the fixed clamping plate 204. There is a slider 202a fixedly connected to the inner bottom of the movable frame 202. There is a movable frame 203 fixedly connected to the other side wall of both the cutting machine guide rail 201 and the fixed clamping plate 204. There is a guide block 203a fixedly connected to the inner bottom of the movable frame 203. There are symmetrically opened sliding grooves on the lower surface of the fabric cutting machine workbench 1. The slider 202a and the guide block 203a are slidably connected inside the sliding grooves. The upper surface of the fixed clamping plate 204... There is an installed mounting frame 204a, and a cylinder 204b is installed on the inner top of the mounting frame 204a.

There are symmetrically opened guide grooves on the two inner side walls of the mounting frame 204a. There are fixed protrusions 204d on the two side walls of the movable clamping plate 204c. The protrusions 204d are slidably connected inside the guide grooves. There is a bidirectional screw 205a commonly arranged between the two movable frames 202. There is a motor 205 installed on the lower surface of the fabric cutting machine workbench 1. The output end of the motor 205 is connected to the end of the bidirectional screw 205a. There is a guide rod 206 commonly arranged through the two movable frames 203.

[0032] Furthermore, the movable frame 202 has a U-shaped structure, the mobile frame 203 has a U-shaped structure, and the mounting frame 204a has an inverted U-shaped structure;

[0033] The operation process of this embodiment is as follows: the free end of the fabric is passed through the top of the fixed clamping plate 204, the cylinder 204b is opened, the piston rod of the telescopic end of the cylinder 204b extends, and the movable clamping plate 204c moves downward toward the fabric until the movable clamping plate 204c cooperates with the fixed clamping plate 204 to clamp the fabric. The motor 205 is powered on, and when the bidirectional lead screw 205a rotates in the forward direction, the two movable frames 202 move in opposite directions. At the same time, the two movable frames 203 move in opposite directions, and the distance between the cutting machine guide rail 201 and the fixed clamping plate 204 gradually increases, and the size of the unwound fabric increases. When the bidirectional lead screw 205a rotates in the reverse direction, the cutting machine guide rail 201 and the fixed clamping plate 204 move toward each other, and the distance between the cutting machine guide rail 201 and the fixed clamping plate 204 gradually decreases, and the size of the unwound fabric decreases. Example 3

The automatic length-fixing component 3 includes a scale 301, a mounting base 303, a switch 303a, a pointing block 303b, an ear block 303c, and a bolt 303d. Loosening the bolt 303d clockwise releases the fixation of the mounting base 303, making it convenient to adjust the position of the switch 303a according to the required fabric cutting size. When the movable frame 202 touches the switch 303a during the movement, the motor 205 is de-energized, stopping the fabric feeding operation. The required fabric cutting size is automatically determined, reducing manual intervention and increasing the accuracy of fabric cutting.

[0035] Specifically, the scale 301 is located on the side wall of the fabric cutting machine workbench 1 and is mounted on the bracket 302. The upper surface of the scale 301 has a guide rail and a mounting base 303. The lower surface of the mounting base 303 has a fixed lug 303c, which is slidably connected to the inside of the guide rail. The upper surface of the mounting base 303 has a threaded bolt 303d that passes through the lug 303c. The side wall of the mounting base 303 has a switch 303a and a pointing block 303b fixed to the side wall of the mounting base 303 is located below the switch 303a.

[0036] Furthermore, the scale value of the ruler 301 increases from the middle to both sides, the guide rail has an inverted T-shaped groove structure, the ear block 303c has an inverted T-shaped structure, and the switch 303a and the motor 205 are electrically connected.

[0037] The operation process of this embodiment is as follows: Loosen the bolt 303d clockwise, that is, the bolt 303d is not pressed against the scale, releasing the fixation of the position of the mounting base 303, pushing the mounting base 303, the ear block 303c slides along the guide rail, and the mounting base 303 moves accordingly. At the same time, the switch 303a and the pointer block 303b move until the scale value pointed to by the pointer block 303b is half of the required fabric cutting size. Tighten the bolt 303d counterclockwise, that is, the bolt 303d presses against the scale 301, fixing the position of the switch 303a. When the movable frame 202 touches the switch 303a during the movement, the motor 205 is turned off, and the fabric cutting machine body set on the cutting machine guide rail 201 is used to cut the fabric.
