Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of electric heating wire cutting device. BACKGROUND

[0002] Fabric cutting is a critical step in the garment manufacturing, home textiles, industrial textiles and other industries involving fabric products. Cutting devices not only ensure the quality of the final product, but also improve production efficiency and reduce material waste.

[0003] Common cutting methods include laser cutting, tool cutting, and electric heating wire cutting. For three-dimensional fabric, conventional tool cutting requires appropriate speed and sufficient pressure during cutting to ensure accuracy and integrity of the cut. However, three-dimensional fabric is suspended, and tool cutting cannot apply sufficient pressure. Laser cutting cannot be used for cutting three-dimensional fabric because the laser has a focal point, and the laser focal points of the upper and lower layers of fabric are not on the same focal point, resulting in unstable energy. Electric heating wire cutting can meet the requirements of three-dimensional cutting because the cut is smooth, so it is commonly used.

[0004] When fabric needs to be cut into a special shape or pattern, the usual method is to use a rotary cutting device, in which the electric heating wire rotates around the shaft. However, there is a certain distance between the electric heating wire support that holds the electric heating wire and the electric heating wire, and the movement trajectory of the electric heating wire support will conflict with the cutting trajectory of the electric heating wire, affecting the final cutting effect. SUMMARY

[0005] The utility model aims to provide a kind of electric heating wire cutting device, to solve the technical problems mentioned in the above background technology.

[0006] The technical solution to achieve the purpose of the utility model is: an electric heating wire cutting device, comprising a rack and a cutting assembly, the cutting assembly is arranged on the rack, the cutting assembly comprises a cutting seat, a rotating support, an electric heating wire support, a power device and an electric heating wire, the cutting seat is connected with the rack, the rotating support is rotatably arranged on the cutting seat, the electric heating wire support is fixed on the rotating support, the electric heating wire is arranged on the electric heating wire support, and the power device drives the rotating support to rotate, the rotating shaft of the rotating support coincides with the cutting part of the electric heating wire.

[0010] Furthermore, the heating wire is L-shaped, a turning portion is provided on the rotating bracket, one end of the heating wire is fixedly connected to the heating wire bracket, and the other end passes around the turning portion of the rotating bracket and is connected to the rotating bracket.

[0011] Furthermore, the cutting assembly also includes a tensioning spring, one end of which is connected to the rotating bracket, and the other end is used to connect to the heating wire, and the tensioning spring is suitable for straightening the heating wire.

[0012] Furthermore, the tensioning spring is connected to the heating wire via a connecting block, and at least one end of the connecting block connected to the tensioning spring is made of insulating material.

The translation component drives the cutting component to move in the transverse horizontal direction, the longitudinal telescopic component drives the cutting component to move in the longitudinal horizontal direction, and the lifting component drives the cutting component to move in the vertical direction.

[0014] By adopting the above technical solution, the utility model has the following beneficial effects:

[0031] See Figure 1 The cutting assembly includes a cutting base 1, a rotating bracket 2, a heating wire bracket 3, a power unit, and a heating wire 4. The cutting base 1 is connected to the frame, and the rotating bracket 2 is rotatably mounted on the cutting base 1. The heating wire bracket 3 is fixed to the rotating bracket 2, and the heating wire 4 is mounted on the heating wire bracket 3. The power unit drives the rotating bracket 2 to rotate; the rotation axis of the rotating bracket 2 coincides with the cutting portion of the heating wire 4. A through hole is provided in the center of the cutting base 1, through which a rotating shaft is passed. The rotating bracket 2 is fixed to one end of the rotating shaft. In this embodiment, the power unit is a pneumatic device, which drives the rotating shaft to rotate, thereby driving the rotating bracket 2 to rotate. The main body of the rotating bracket 2 is made of nylon.

[0032] The heating wire 4 is L-shaped. A metal turning portion 2-1 is provided on the rotating bracket 2.
