Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to an automatic positioning laser cutting machine. Background Art

[0002] A laser cutting machine is an industrial device that uses laser technology to cut materials. It focuses the laser beam emitted from the laser onto a very small focal point, generating high energy density. This rapidly heats the material at that focal point to its melting or boiling point, achieving the desired effect. Laser cutting machines are widely used in a variety of industries, including metal processing, automotive manufacturing, aerospace, electronics, and handicraft production.

[0003] Laser cutting machines offer high-precision, high-speed cutting performance for a wide range of fabrics, including but not limited to cotton, silk, nylon, and polyester. However, existing laser cutting machines can leave waste material stuck to the finished fabric after cutting, requiring manual separation. This increases the need for secondary processing and reduces both machine efficiency and cutting efficiency.

[0004] Therefore, a laser cutting machine with automatic positioning that is convenient for material separation is needed. Utility Model Content

[0005] In order to overcome the disadvantage that after the existing laser cutting machine completes the fabric cutting, waste materials and the cut fabric will stick together, and manual separation of the waste materials and the cut fabric is required, thereby increasing the demand for secondary processing and reducing the efficiency of the cutting machine and the efficiency of the cutting work, the utility model provides a laser cutting machine with automatic positioning that is convenient for material separation.

[0011] Optionally, a collection box is further included, and the collection box is placed on the fixed frame.

[0012] Compared with the prior art, the utility model provides an automatic positioning laser cutting machine with the following beneficial effects: 1.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: An automatic positioning laser cutting machine, see Figure 1-Figure 5 , including a base frame 1, a transmission component 2, a fixed plate 3, a first motor 4, a first screw 5, a slide plate 6, a second motor 7, a second screw 8 and a laser cutting machine body 9. A transmission component 2 is provided on the base frame 1, and fixed plates 3 are provided on both sides of the base frame 1 by welding. The first motor 4 is installed on the fixed plate 3 on the right side, and the output shaft of the first motor 4 is connected to the first screw 5 through a coupling. The two fixed plates 3 are slidingly provided with a slide plate 6, and the slide plate 6 is threadedly connected to the first screw 5. The second motor 7 is installed on the right side of the slide plate 6, and the output shaft of the second motor 7 is connected to the second screw 8 through a coupling. A laser cutting machine body 9 is slidingly provided on the slide plate 6, and the laser cutting machine body 9 is threadedly connected to the second screw 8. A fixed frame 10 is provided on the front side of the base frame 1 by welding, and a rotating fixed frame 10 is provided on the fixed frame 10. A winding rod 11 is provided, and a connecting shaft 12 is provided on the right side of the transmission component 2 by welding. The connecting shaft 12 and the winding rod 11 are jointly provided with a pulley group 13, which consists of two pulleys and a belt. A pulley is provided at the right end of the connecting shaft 12, and another pulley is provided at the right end of the winding rod 11. The two pulleys are jointly provided with a belt, and the connecting shaft 12 and the winding rod 11 are jointly provided with a protective cover 18. The pulley group 13 is located inside the protective cover 18, thereby protecting the pulley group 13 to prevent foreign matter from being entangled in the pulley group 13. A guide plate 19 is provided on the fixed frame 10 by welding. The guide plate 19 guides the cut cloth so that the cloth falls forward. A collecting box 20 is placed on the fixed frame 10. The collecting box 20 is used to collect the cut cloth.

[0023] When the cloth needs to be cut, the cloth is first placed on the conveying assembly 2, and then the conveying assembly 2 is started. The conveying assembly 2 operates to convey the cloth forward. At the same time, the first motor 4, the second motor 7 and the laser cutting machine body 9 are started by the automatic positioning system. The output shaft of the first motor 4 rotates to drive the first screw 5 to rotate, so that the slide 6 drives the laser cutting machine body 9 to move forward and backward along the fixed plate 3. The output shaft of the second motor 7 rotates to drive the second screw 8 to rotate, so that the laser cutting machine body 9 moves left and right along the slide 6, thereby realizing the full range of movement of the laser cutting machine body 9 in the XY plane. In this process, the cutting head of the laser cutting machine body 9 cuts the cloth, and then the waste generated by the cutting is wound on the winding rod 11. As the conveying assembly 2 continues to operate, the connecting shaft 12 is driven to rotate. The rotation of the connecting shaft 12 further drives the pulley group 13 to rotate, thereby rotating the winding rod 11 to rewind the waste, thereby separating the waste from the cut cloth. No secondary processing is required, thereby improving the efficiency of the cutting machine and the efficiency of the cutting work.

[0024] Example 2: Based on Example 1, please refer to Figure 1 and Figure 4 , both sides of the fixed frame 10 are slidably provided with fixed rods 14, and the two fixed rods 14 are jointly provided with a pressure rod 15, and a limit rod 1401 is inserted into the fixed rod 14. When the height of the pressure rod 15 needs to be adjusted, the limit rod 1401 is first pulled out, and then the fixed rod 14 is pushed to drive the pressure rod 15 to move, and the height of the pressure rod 15 is adjusted. After the adjustment is completed, the limit rod 1401 is inserted into the corresponding position of the fixed rod 14.

[0025] Before the waste material produced by cutting is wound, the waste material should first pass under the pressure rod 15, and then continue to pull the waste material forward so that it is wound around the winding rod 11. When the conveying component 2 conveys the cut cloth forward, the rotation of the winding rod 11 will tighten the cloth, and the pressure rod 15 will contact the cloth, separating the cut cloth from the waste material, thereby preventing the cut cloth from sticking to the waste material.

[0026] See also Figure 1 and Figure 4 Two guide rods 16 are provided on the top of the fixing plate 3 by welding. A lighting lamp 17 is installed on the two fixing plates 3. The guide rods 16 pass through the base of the lighting lamp 17.

[0027] In the case of dim light, the lighting lamp 17 is turned on to fully illuminate the cutting area, making it easier to find the cutting position accurately, thereby improving the cutting effect.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
