Description

Technical Field

[0001] The utility model relates to the field of laser cutting equipment, in particular to a multi-point laser cloth cutting device. Background Art

[0002] Laser cutting is used for fabric cutting. It does not come into contact with the fabric, does not cause blade wear, has the characteristics of no burrs, standard size, small error, etc., and is widely used in embroidery machines. In embroidery machines, it is often necessary to cut fabrics in multiple locations. For this situation, current embroidery machines generally use the following methods:

[0003] First, multiple lasers are used to cut fabrics at multiple locations. This method requires a large amount of lasers and increases the manufacturing cost of the embroidery machine.

[0004] Secondly, a mobile laser is used, that is, a laser moves back and forth in multiple locations to cut the cloth in each location. This method has the problem of low laser movement efficiency, especially when the distance between multiple cutting locations is large, which will affect the cutting efficiency of the cloth in two locations; and it may also cause laser jitter, affecting the life of the laser. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-point laser cloth cutting device that can cut cloth in three parts by one laser, which can not only save costs but also has high cutting efficiency, and can effectively solve the problem of using a mobile laser to cut different parts of the cloth, which affects the cutting efficiency.

[0006] The technical solution of the utility model is:

[0007] A multi-point laser cloth cutting device, comprising:

[0008] Rack and laser;

[0009] A rotating mirror frame is provided with two moving lenses, and a laser port is provided on the rotating mirror frame between the two moving lenses;

[0010] A fixed lens, fixedly arranged below the laser port;

[0011] The rotary drive mechanism drives the rotating mirror frame to rotate, so that the laser emitted by the laser is projected onto one of the moving lenses or the other moving lenses, or onto the fixed lens through the laser port. When the multi-point laser cloth cutting device is working, the rotating mirror frame is driven to rotate by the rotary drive mechanism, so that the laser emitted by the laser is projected onto one of the moving lenses, and the moving lens generates reflected light to cut the cloth at one part of the embroidery machine;

[0012] The rotating mirror frame is driven to rotate by a rotary drive mechanism, so that the laser emitted by the laser is projected onto another moving mirror, and the moving mirror generates reflected light to cut the fabric at another part of the embroidery machine;

[0013] The rotating mirror frame is driven to rotate by a rotary drive mechanism, so that the laser emitted by the laser is projected onto the fixed lens through the laser port, and the fixed lens generates reflected light to cut the fabric at the third part of the embroidery machine; thus, the fabric at three different parts of the embroidery machine can be cut by one laser, saving costs. More importantly, the laser of this solution is fixed, and the rotating mirror frame is driven to rotate by a rotary drive mechanism to cut the fabric at three parts of the embroidery machine. In this way, the cutting part of the fabric can be quickly switched, and different parts of the fabric can be quickly cut, so that the cutting efficiency is high, which can effectively solve the problem of using a mobile laser to cut different parts of the fabric, which affects the cutting efficiency.

[0014] Preferably, three light guide pipes are included, one of which corresponds to a moving lens, another corresponds to another moving lens, and the third corresponds to a fixed lens;

[0015] The light guide includes a focusing mirror and at least one reflecting mirror. The light reflected by the moving mirror or the fixed mirror enters the corresponding light guide and is reflected by the reflecting mirror of the corresponding light guide to the focusing mirror for focusing. In this way, the laser path can be adjusted by the reflecting mirror, and then the position of the fabric cutting part can be adjusted to meet the actual cutting needs.

[0016] Preferably, the same light guide has two reflectors, and after the light enters the corresponding light guide, it is reflected twice by the two reflectors and then enters the focusing lens. In this way, the laser path can be adjusted more flexibly through the two reflectors, and the position of the fabric cutting part can be adjusted more flexibly to meet the actual cutting needs.

[0017] Preferably, the light guide pipeline includes a light guide protective tube, and the light guide protective tubes of the two light guide pipelines corresponding to the moving lens are located on opposite sides of the rotating lens frame, and the light entering the light guide pipeline is transmitted in the protective tube of the same light guide pipeline. In this way, on the one hand, the light guide protective tube can be used to ensure that the laser path is not blocked by foreign objects, and on the other hand, it can effectively prevent objects or people from contacting the laser, so as to protect objects and operators.

[0018] Preferably, the light guide protective tube is installed on the frame via a bracket, the light guide protective tube is connected to the bracket via bolts, and the bracket is connected to the frame via bolts, so as to facilitate the actual installation, disassembly and adjustment of the light guide protective tube.

[0019] Preferably, the light reflected by the moving lens enters the corresponding light guide through the laser port. This is beneficial to the arrangement of the two moving lenses and the fixed lens on the rotating lens frame, and the rotating lens frame is driven to rotate by the rotary drive mechanism, so that the laser emitted by the laser is incident on one of the moving lenses or the other moving lens, or is incident on the fixed lens through the laser port.

[0020] Preferably, two limit parts for limiting the rotation angle of the rotating mirror frame are provided on the frame. When the rotating mirror frame abuts against one of the limit parts, the laser emitted by the laser is emitted onto one of the moving lenses; when the rotating mirror frame abuts against the other limit part, the laser emitted by the laser is emitted onto the other moving lens.

[0021] Preferably, the two moving mirror plates are arranged in parallel, so as to facilitate the arrangement of the two moving mirror plates.

[0022] Preferably, the laser is mounted on the frame, the laser emits laser downward, the laser emission port of the laser is located above the rotating mirror frame, and the laser emission port of the laser is located above the fixed mirror. In this way, the installation and arrangement of the laser are facilitated.

[0023] Preferably, the rotary drive mechanism is a motor or a rotary pump.
