Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, and more specifically, to a laser cutting machine. Background Art

[0002] The upper is an important part of shoes and is generally made of materials such as fabric, rubber and leather.

[0003] When leather is made into shoe upper accessories, it needs to be cut. Existing materials are cut using lasers, which has high processing efficiency and precise size.

[0004] When cutting leather, it needs to be unfolded on the laser cutting machine. However, when displayed, wrinkles and bends often appear, making the leather uneven. Cutting in this state can easily lead to reduced cutting accuracy and affect subsequent processes.

[0005] This application provides another technical solution to this technical problem. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a laser cutting machine.

[0007] The above technical objectives of the utility model are achieved through the following technical solutions:

[0008] The laser cutting machine comprises a chassis and a cover. A support plate and a gantry are installed in the chassis. A laser head is installed on the gantry. The support plate is provided with a plurality of air ports. An air collecting hood corresponding to the plurality of air ports is fixedly installed on the support plate. The air collecting hood is formed with a connecting pipe connected to an air pump. The chassis is provided with two smoothing members that are slidably driven by a driving assembly, and the sliding directions of the two smoothing members are opposite.

[0009] The utility model is further configured as follows: the smoothing member comprises a bracket and a smoothing plate which rotates on the bracket through a rotating shaft, and the bracket is provided with a force applying member which controls the smoothing plate to rotate.

[0010] The utility model is further configured as follows: the rotating shaft sleeve is provided with a torsion spring, both ends of the torsion spring are connected to the bracket and the smoothing plate, the force applying member comprises an electromagnet installed on the bracket, and the smoothing plate is fixedly installed with magnetic metal.

[0011] The utility model is further configured as follows: a rubber rod is rotatably connected to the caressing plate.

[0012] The utility model is further configured as follows: a slide rail is installed between the chassis and the bracket.

[0013] The utility model is further configured as follows: the driving assembly comprises a motor group installed on the slide rail, and the motor group is used for driving the slide rail to slide.

[0014] In summary, the utility model has the following beneficial effects:

[0015] When the leather is spread flat on the support plate, and the electromagnet is controlled to attract the magnetic metal, the smoothing plate overcomes the elastic force of the torsion spring and rotates to press the leather. Then the vacuum pump is controlled to work and several air ports are used to inhale air. The airflow at the air ports will make the leather stick to the support plate. Then the motor group is controlled to move the smoothing plate. The smoothing plate will smooth the leather, and the leather will not move at will during the smoothing process due to the attraction of the airflow, thereby ensuring the smoothing effect. This can increase the flatness of the leather and ensure the quality of subsequent continuous cutting. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0022] like Figure 1As shown, the present application provides a laser cutting machine, including a chassis 1 and a cover 2, the cover 2 rotates on the chassis 1, and a support plate 3 and a gantry 4 are fixedly installed in the chassis 1, and the gantry 4 is equipped with a laser head 5, the laser head 5 will move above the support plate 3 under the action of the gantry 4, when cutting the leather, the leather is laid flat on the support plate 3, the cover 2 is closed, and the laser head 5 will move and cut under the action of the gantry 4, and then the leather will be cut into a desired shape.

[0023] like Figure 2 and Figure 3 As shown, the support plate 3 is provided with a plurality of air ports 6, and an air collecting hood 7 corresponding to the plurality of air ports 6 is fixedly mounted on the support plate 3. The air collecting hood 7 is formed with a connecting pipe connected to the air pump. When the air pump is working, the gas near the air ports 6 will enter the air collecting hood 7 through the air ports 6, and finally be collected in the air pump through the connecting pipe. After the leather is laid flat on the support plate 3, the airflow will attract the leather, making the leather close to the support plate 3, thereby increasing the stability of the leather on the support plate 3. At the same time, when cutting, the smoke generated by the cutting will flow with the airflow, thereby reducing the probability of the smoke diffusing to the outside of the chassis 1.

[0024] like Figure 3 and Figure 4 As shown, the chassis 1 is provided with two smoothing members through a driving assembly for sliding, wherein the smoothing members include a bracket 8 and a smoothing plate 10 that rotates on the bracket 8 through a rotating shaft 9, a slide rail 12 is installed between the chassis 1 and the bracket 8, the bracket 8 and the smoothing plate 10 can slide along the slide rail 12, the rotating shaft 9 is sleeved with a torsion spring 11, and both ends of the torsion spring 11 are connected to the bracket 8 and the smoothing plate 10, when the leather is laid flat on the support plate 3, the smoothing plate 10 will maintain a gap between the smoothing plate 10 and the support plate 3 due to the elastic force of the torsion spring 11, so that there is no need to manually operate the smoothing plate 10, which is convenient for laying the leather on the support plate 3, thereby increasing the convenience of operation.

[0025] like Figure 3 and Figure 4 As shown, the bracket 8 is provided with a force-applying member, which includes an electromagnet 14 installed on the bracket 8, and a magnetic metal 15 is fixedly installed on the smoothing plate 10. When the leather is placed on the supporting plate 3, the electromagnet 14 is energized, and the electromagnet 14 attracts the magnetic metal 15, so that the smoothing plate 10 overcomes the elastic force of the torsion spring 11 and rotates, so that the smoothing plate 10 is pressed on the leather, which can reduce the probability of the leather position being offset during cutting and ensure the cutting quality.

[0026] like Figure 3 and Figure 4As shown, the driving assembly includes a motor group 13 installed on the slide rail 12, and the motor group 13 is used to drive the slide rail 12 to slide. When the leather is laid flat on the support plate 3 and the smoothing plate 10 is pressed on the leather, the motor group 13 is controlled, and the motor group 13 will make the two smoothing plates 10 move away from each other. Due to the air flow at the air port 6, the leather will be tightly attached to the support plate 3. The leather cannot move freely during the smoothing process, ensuring the smoothing effect. This can increase the flatness of the leather and ensure the quality of subsequent continuous cutting. A rubber rod 16 is rotatably connected to the smoothing plate 10. The rubber rod 16 can reduce the friction between the leather and the rubber rod 16 while ensuring the pressure on the leather, thereby reducing the probability of wear on the leather.

[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
