Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a garment fabric trimming machine. Background Technology

[0002] Clothing is a general term encompassing clothes, shoes, and accessories, but primarily refers to clothing. In national standards, clothing is defined as: sewn products worn on the human body for protection and decoration; also known as garments. Clothing production largely utilizes assembly line processing methods.

[0003] A Chinese patent, CN221398451U, discloses a garment fabric trimming machine. It utilizes a motor to drive a reducer, which in turn drives a connecting shaft. This shaft in turn drives a bidirectional lead screw, which in turn causes a first and second slider to move relative to each other. This, in turn, causes a first and second cutter to move relative to each other, allowing adjustment of the distance between the two cutters. When the distance measured by the rangefinder reaches a set value, it transmits a signal to the controller, which then shuts off the motor. This method is simple, convenient, and quick, facilitating trimming of fabrics of different sizes. The second and third electric telescopic rods lower the first and second cutters, allowing them to trim the fabric edges. However, with prolonged use, the cutters wear down, resulting in uneven trimming and continuous fiber pulling leading to incomplete breakage. Knitted fabrics are prone to loop unraveling and jagged edges. Therefore, this garment fabric trimming machine is proposed to address these problems. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a garment fabric trimming machine. By using a vibration component to make two cutters vibrate continuously at high frequency, it helps the blades penetrate multiple layers of fabric more smoothly, reduces the relative slippage between layers, ensures higher alignment of the edges of each layer, and reduces resistance and energy consumption.

[0005] This utility model provides a garment fabric trimming machine, including a worktable, a frame, two rollers, and a limiting mechanism. The frame is connected to the top of the worktable, the two rollers are disposed between the left and right walls of the frame, and the limiting mechanism is disposed inside the frame and between the two rollers. It also includes a drive frame, two movable frames, and two blade holders. The drive frame is connected to the top of the frame, the two movable frames are spaced apart and positioned directly below the drive frame, and the two blade holders are rotatably disposed within the two movable frames. Each blade holder is equipped with a cutting blade. The drive frame is equipped with a drive mechanism that drives the two movable frames to move relative to or away from each other, and each movable frame is equipped with a vibration mechanism that drives the blade holders to vibrate continuously up and down.

[0006] Preferably, the bottom and front sides of both movable frames are missing, and a rangefinder is provided on the rear side of both movable frames.

[0007] Preferably, each of the vibration mechanisms includes a first motor, a rotating rod, a cam, a slide rod, a pressure block, and a spring. The first motor is disposed at the top of the moving frame. One end of the rotating rod is coaxially connected to the output shaft of the first motor. The cam is coaxially fixedly sleeved on the rotating rod. The slide rod is fixedly connected to the tool holder, and its two ends extend to the left and right sides of the moving frame, respectively. The pressure block is fixedly sleeved on the slide rod. The spring is connected between the top wall of the moving frame and the top of the tool holder.

[0008] Preferably, the movable frame has arc-shaped windows on both the left and right sides, and the slide rod is slidably connected to the inner walls of the two arc-shaped windows.

[0009] Preferably, the drive mechanism includes a second motor, a bidirectional lead screw, and two connecting frames. The second motor is located on the left side of the drive frame. One end of the bidirectional lead screw is coaxially connected to the output shaft of the second motor, and the other end is rotatably connected to the right side wall of the drive frame. The two connecting frames are threadedly connected to the bidirectional lead screw and extend into the frame. Two multiple movable frames are respectively connected to the two connecting frames.

[0010] Preferably, the bottom end of the drive frame and the top end of the stand are provided with sliding windows that are adapted to the size of the two connecting frames.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By setting a drive mechanism to drive two moving frames to move relative to or away from each other, the distance between the two moving frames can be adjusted to trim the edges of fabrics of different widths. By setting a shaking mechanism on the two moving frames, the two blade holders drive the two cutting blades to shake up and down continuously, which trims the two edges of the fabric, reduces burrs and snags, prevents deformation and slippage, reduces wear, prevents blade sticking, and greatly improves the life of the blades.

The frame 2 is connected to the top of the worktable 1. The two rollers 3 are disposed between the left and right walls of the frame 2. The limiting mechanism is disposed inside the frame 2 and located between the two rollers 3. The machine also includes a drive frame 4, two moving frames 6, and two knife holders 7. The drive frame 4 is connected to the top of the frame 2. The two moving frames 6 are disposed at intervals directly below the drive frame 4. The two knife holders 7 are rotatably disposed inside the two moving frames 6. Each of the two knife holders 7 is provided with a cutting blade 71.

When the material passes through, the drive mechanism is activated to adjust the two moving frames 6 to move relative to or away from each other. Then, the shaking mechanism drives the two blade holders 7 to continuously shake the cutter 71 up and down, so that the cutter 71 continuously cuts the material.

[0024] In an optional embodiment, the bottom and front sides of both movable frames 6 are missing, and a rangefinder 61 is provided on the rear side of both movable frames 6.

[0027] It should be noted that when the drive cutter 71 vibrates up and down continuously, the first motor 81 is started to drive the rotating rod 82 to rotate, which in turn drives the cam 83 to rotate, continuously pressing down the pressure block 85. The pressure block 85 drives the slide rod 84 and the cutter holder 71 to continuously press down and rise, cutting the fabric.

[0028] In an optional embodiment, the movable frame 6 has arc-shaped windows on both the left and right sides, and the slide bar 84 is slidably connected to the inner walls of the two arc-shaped windows.
