Technical Field
[0001] The utility model relates to the technical field of engraving machines, in particular to a double-station laser engraving machine. Background Art
[0002] Laser marking machine, also called laser engraving machine, can improve the efficiency of engraving, make the surface of the engraved part smooth and round, quickly reduce the temperature of the engraved non-metallic material, and reduce the deformation and internal stress of the engraved object. According to the different laser light sources, it can be divided into CO2 non-metallic laser marking machine and optical fiber metal marking machine. In the production of sports products, it is often used for the marking of sports product leather.
[0003] For example, Chinese patent authorization announcement number CN 214322212 U discloses a laser engraving machine, including a machine body, a storage box is arranged at the bottom of the machine body, a motor is fixedly connected to the top of the inner cavity of the storage box, a lead screw is fixedly connected to the output end of the motor, the bottom of the lead screw is movably connected to the storage box through a bearing, a sleeve is threadedly connected to the surface of the lead screw, both sides of the sleeve are fixedly connected to limit rods, both sides of the inner cavity of the storage box are fixedly connected to vertical plates, and the bottom of the limit rod is fixedly connected to legs. The utility model has the advantages of easy movement and gas filtration through the coordinated use of the machine body, storage box, motor, lead screw, sleeve, limit rod, vertical plate, legs, rollers, placement plate, filter box, negative pressure fan, filter net, air collecting pipe, air collecting hood and air outlet pipe, which solves the problem that the existing laser engraving machine is not easy to move and does not have the function of gas filtration, thus failing to meet the needs of users;
[0004] By reviewing the above comparative documents, it can be seen that the prior art still has the following deficiencies. In sports products, it is often necessary to use a CO2 non-metallic laser engraving machine to engrave the leather of sports products. Generally, the leather is directly placed on the engraving table for engraving. If there are no measures to limit and prevent the leather from slipping, once the leather slips, it is easy to cause a large deviation in the engraving accuracy of the leather, affecting the quality of the leather engraving. If the leather is limited by clamping, the engraving surface of the leather will be blocked, resulting in an engraving blind area, affecting the normal progress of the leather during engraving. In addition, the existing engraving machine is generally a single-station engraving. After the previous piece of leather is engraved, it is often necessary to manually cut the engraved leather, resulting in insufficient automatic and convenient unloading. Utility Model Content

[0008] A proximity switch is installed on the left side of the concave imprinting table, and a proximity plate connected to the inner wall of the machine body is provided on the upper left side of the I-shaped bracket, and the proximity switch corresponds to the proximity plate;
[0009] The I-shaped bracket is provided with a flip driving component outside.

DETAILED DESCRIPTION

[0026] When the leather of sports products is engraved by the engraving machine, the leather is first placed on the mesh plate 9 on the concave engraving table 3, and the upper proximity switch 18 is close to the proximity plate 19, and the proximity switches 18 are set one by one to be connected in series with the adjacent vacuum pump 10, so the proximity switch 18 is started and controls the upper vacuum pump 10 to be powered on, and the vacuum pump 10 sucks air through the vacuum pipe 11, the suction pipe 12, the interconnecting pipe 17 and the suction hood 13. The suction force will absorb the leather through the mesh holes of the mesh plate 9, which is conducive to firmly adsorbing the leather on the mesh plate 9, and is conducive to anti-slip limiting of the leather, avoiding accidental slippage of the leather during engraving, effectively ensuring the accuracy and quality of the leather during engraving, and the engraving surface of the leather is not blocked, thereby avoiding the occurrence of engraving blind spots, effectively ensuring the normal progress of the engraving process.
[0027] like Figure 1-3 As shown, in this embodiment, the exhaust gas purification components are arranged outside the air pump 10, and the exhaust gas purification components are composed of a filter box 14, an air filter element 15 and an exhaust pipe 16. The filter box 14 is connected to the exhaust port of the air pump 10, the air filter element 15 is installed in the filter box 14, and the exhaust pipe 16 is connected to the left side of the filter box 14;
[0028] When the leather is placed on the mesh plate 9 for engraving, that is, when smoke is generated by the laser engraver 2 when engraving the leather, the suction hood 13 will generate suction, and under the premise that the leather does not completely cover the suction hood 13, the unblocked suction hood 13 will absorb the smoke generated by the engraving, and the smoke enters the suction pump 10 through the suction hood 13, the interconnecting pipe 17, the suction pipe 12 and the exhaust pipe 11, and is then discharged into the filter box 14, and then the smoke is filtered and purified by the air filter element 15, and finally discharged through the exhaust pipe 16, thereby helping to reduce the pollution of the smoke to the environment, and the suction hood 13 not only has the function of adsorbing and limiting the leather, but also has the function of absorbing smoke, making the improvement direction of the engraving machine more practical.
[0029] like Figure 1 , 2 As shown, in this embodiment, a proximity switch 18 is installed on the left side of the concave imprinting table 3, and a proximity plate 19 connected to the inner wall of the body 1 is provided on the upper left of the I-shaped bracket 4, and the proximity switch 18 corresponds to the proximity plate 19. The I-shaped bracket 4 is provided with a flip drive assembly outside, and the flip drive assembly is composed of a bearing shaft 5, a motor 6, a main gear 7 and a sub-gear 8. The bearing shaft 5 is provided with two and is respectively fixed to the left and right ends of the I-shaped bracket 4, and the end of the bearing shaft 5 is rotatably connected to the inner wall of the body 1, the motor 6 is fixed to the inner wall of the body 1, the main gear 7 is connected to the power end of the motor 6, and the sub-gear 8 is fixedly sleeved on the periphery of one of the bearing shafts 5, and the main gear 7 is meshed with the sub-gear 8;
[0030] After the leather on the upper concave imprinting table 3 is imprinted, the main gear 7, the sub-gear 8 and the bearing shaft 5 are driven to rotate by the operation of the motor 6, and the bearing shaft 5 will drive the I-shaped bracket 4 and the concave imprinting table 3 to flip together until the upper and lower concave imprinting tables 3 are flipped up and down and exchanged positions. In this process, when the upper concave imprinting table 3 is flipped down, the proximity switch 18 on the concave imprinting table 3 is away from the proximity plate 19, the proximity switch 18 is disconnected and the corresponding vacuum pump 10 is automatically controlled to be powered off, that is, when the mesh plate 9 on the concave imprinting table 3 is facing downward, the suction hood 13 stops sucking air, so the leather on the lower concave imprinting table 3 will automatically unload and fall off. In summary, by setting a double-station concave imprinting table 3 and then changing the processing position of the concave imprinting table 3 by flipping, when the vacuum pump 10 below stops working, the leather on the lower concave imprinting table 3 will automatically fall, thereby completing the effect of automatic unloading, effectively ensuring the automatic convenience of unloading work.
