Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a lifting type laser cutting machine for a sewing machine. Background Art

[0002] A laser cutting machine is a device that focuses the laser emitted from a laser into a high-power density laser beam through an optical path system and then cuts objects through a high-power density laser beam. The laser beam irradiates the surface of the object, causing the surface temperature of the object to reach the melting point or boiling point. As the beam and the object continue to move relative to each other, a cut is produced on the surface of the object, thereby achieving the purpose of cutting.

[0003] Laser cutting machines are widely used in the textile industry. Together with a module that can move on a processing table according to a preset program, the fabric carried on the module can be quickly cut into the required shape, effectively replacing traditional manual cutting. It has high cutting accuracy and fast cutting speed, and is particularly convenient for cutting and processing textile product fabrics in large quantities.

[0004] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: when the existing laser cutting machine is used in the textile industry, it is fixed on the processing table and cannot change the angle and height. It can only cut by coordinating the movement of the module. In order to prevent the laser beam intensity from being lost, it is necessary to reduce the distance between the laser cutting machine and the cloth, which will cause the module to hit the laser head when it moves to the position of the laser cutting machine laser head, limiting the movement distance of the module. If sewing is required after cutting, the module needs to move and migrate over a large range, which makes the volume of the entire equipment too large and reduces work efficiency. Utility Model Content

[0005] The utility model aims to provide a lifting type laser cutting machine for a sewing machine which can prevent the module from being blocked and has high working efficiency in view of the defects and shortcomings of the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a lifting type laser cutting machine for a sewing machine, comprising a light source bracket and a light guide beam arranged at the upper end of the light source bracket, a laser head is arranged at the end of the light guide beam, the laser head comprises a fixing plate fixedly connected to the end of the light guide beam and a polarizing filter arranged on the fixing plate, a lifting structure is also arranged on the outer wall of the fixing plate, a light guide tube is fixedly arranged on the inner wall of the lifting structure, a laser cutting head is arranged at the lower end of the light guide tube, the light guide tube conducts laser and emits laser through the laser cutting head for cutting, and after cutting, the light guide tube can be driven to rise and fall by the lifting structure to avoid collision with the cloth module.

[0007] A further improvement is that the outer wall of the light source bracket is also provided with a plurality of threaded hole connecting plates.

[0008] A further improvement is that the lifting structure includes a guide block fixedly connected to the outer wall of the fixed plate and a guide column slidably connected to the guide block, a lifting plate fixedly connected to the outer wall of the light guide tube is provided at the bottom of the guide column, and a push-pull cylinder fixedly connected to the outer wall of the fixed plate is provided on the lifting plate.

[0009] A further improvement is that: a connecting plate is provided on one side of the push-pull cylinder close to the fixing plate, and a penetration hole is penetrated through the connecting plate so that the light guide tube can penetrate.

[0010] A further improvement is that: the lifting plate is also provided with an L-shaped protruding frame, and the top surface of the protruding frame is fixedly connected to the bottom end of the push-pull cylinder.

[0011] A further improvement is that: two guide posts are provided, and the two guide posts are symmetrically distributed on the lifting plate along the vertical center line of the lifting plate.

[0012] A further improvement is that: the guide blocks are provided with four, and the four guide blocks are divided into two groups, two in a group, and are slidably arranged on the guide column.

[0013] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: during the cutting process, the utility model controls the lifting structure to lower the laser cutting head so that the laser energy can be fully applied to the cloth, and rises after the cutting to make the height of the laser cutting head higher than the module, thereby avoiding affecting the movement of the module, so that it can directly pass through the position of the laser cutting head without large-scale migration, reducing the volume of the entire equipment and improving work efficiency.
