Description

Technical Field

[0001] The utility model relates to the technical field of backpack production, in particular to a sample cutting device for backpack production. Background Art

[0002] Sample cutting is the process of cutting fabric into appropriate shapes and sizes according to design drawings. In backpack production, there are two main types of sample cutting equipment: manual and automatic. Manual cutting equipment typically uses a manually operated cutter to cut the fabric, making it suitable for small-batch production. Automatic cutting equipment, on the other hand, uses a CNC system to drive the cutter and is more suitable for large-scale industrial production.

[0003] The existing manual cutting equipment is prone to causing wrinkles in the fabric during movement, especially when cutting soft or light fabrics. Such wrinkles can lead to irregular cutting lines or dimensional errors. In order to avoid cutting errors, additional operators are usually required to manually straighten the fabric, which increases labor costs and reduces production efficiency.

[0004] Therefore, it is necessary to develop a kind of cutting equipment for backpack production to solve the above-mentioned technical defects. Utility Model Content

[0005] The purpose of the utility model is to provide a cutting device for backpack production, so as to solve the problem of cutting errors caused by wrinkles on the fabric surface proposed in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cutting device for backpack production, comprising a fixer and a shell, the bottom end of the fixer is fixedly connected to the shell, the top end of the shell is movably connected to a connecting seat, the bottom end of the connecting seat is fixed with a fixing rod, the outside of the fixing rod is fixedly connected to a connecting frame, and a group of flat material structures are installed on each side of the connecting frame; the flat material structure includes racks fixed on both sides of the connecting frame, the outer sides of the racks are respectively meshed and connected with gears, the center of the gear axis is fixedly connected with a mounting ring, the bottom end of the mounting ring is fixedly connected with a sleeve, the bottom end of the sleeve is movably connected with a spring rod, the bottom end of the spring rod is fixedly connected with a rotating piece, and the spring rod is movably assembled with an arc piece through the rotating piece.

[0007] As a further technical solution of the present invention, the arc piece is a 0.5 cm metal sheet, and the arc piece is warped upward to a plane distance of 1 cm.

[0008] As a further technical solution of the present invention, two groups of gears are provided, and the gear axes are movably assembled on the inner wall of the shell.

[0009] As a further technical solution of the present invention, bolts are fixedly connected between the connecting frame and the racks, and the racks are provided in two groups and are parallel to each other.

[0010] As a further technical solution of the present invention, the top of the shell is fixedly connected to a cylinder seat, the bottom of the cylinder seat is fixed to a lifting cylinder, the output end of the lifting cylinder is provided with a piston rod, and the bottom end of the piston rod is fixedly connected to the connecting seat.

[0011] As a further technical solution of the present utility model, the bottom end of the fixed rod is fixedly connected to a tool holder, bearings are installed on both sides of the inner wall of the tool holder, the tool holder is equipped with a cutting knife through the bearings, a drive motor is fixed to the right side of the outer wall of the tool holder, the drive motor is fixedly connected to the cutting knife, and bottom grooves for the movement of the arc piece are opened on both sides of the bottom end of the shell.

[0012] As a further technical solution of the present invention, a knife groove is provided between the bottom grooves, and the bottom end of the cutting knife extends below the knife groove.

[0013] As a further technical solution of the present invention, a handle is fixedly connected to the right side of the bottom end of the holder, and a slide plate is welded to the bottom end of the handle.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the cutting device for backpack production not only realizes the smoothing of the nearby fabric surface before cutting, thereby preventing dislocation due to wrinkles and eliminating the need for manual operation, thereby improving cutting accuracy, but also realizes the automatic interruption of the cutting path and automatic knife extension and retraction in a coordinated manner, and realizes simple and fast operation with low labor intensity;

[0015] (1) By providing a flat material structure, when the cutter is cutting the cloth, the lifting cylinder pushes it downward to extend out of the knife groove. During the process of the cutter descending, the connecting frame moves downward accordingly, and the racks fixed on both sides of the connecting frame move downward, then the gear rotates clockwise, and the mounting ring fixed on the gear drives the arc piece to flip clockwise. When the arc piece is released to the surface of the cloth, under the action of the spring rod extension and contraction, the arc piece is squeezed and rotated, and the cloth near the cutting line is smoothed, so that the cloth will not be misplaced due to wrinkles during cutting, and no manual operation is required, thereby improving the cutting accuracy;

[0016] (2) By setting up a cylinder seat, a lifting cylinder, a piston rod, a connecting seat, a fixed rod, and a connecting frame, cutting is divided into three steps. First, the lifting cylinder drives the fixed rod to descend, and the cutter extends from the knife groove. During this process, the arc piece smoothes the cloth surface. Second, the driving motor drives the cutter to rotate at high speed, and the cloth is cut along the cutting line during the movement. Third, when the moving trajectory is interrupted, the cylinder seat automatically retracts the piston rod, and the cutter is retracted into the shell, and the arc piece is lifted. The coordinated action automatically interrupts the cutting path, and the knife is automatically extended and retracted, which is more protective.

[0017] (3) By setting a handle and a slide, when cutting, the user can hold the handle and control the opening of the cutter and the lifting of the lifting cylinder through the case. When the handle is moved, the slide pushes the device to slide on the cloth surface, which has a flexible cutting function, simple and fast operation, and low labor intensity.
