Abstract
Description
Technical Field
[0001] This utility model belongs to the field of leather fixture technology, and in particular relates to a translucent leather laser engraving fixing fixture. Background Technology
[0002] In the leather industry, laser engraving machines are increasingly widely used. They can quickly engrave and hollow out various exquisite patterns on various leather materials. They are flexible in operation and will not deform the leather surface, which can well reflect the color and texture of the leather itself and greatly improve the aesthetics of leather products.
[0003] However, laser engraving requires the use of a fixture to restrain the leather. Currently, existing leather laser engraving fixtures have some significant drawbacks. On the one hand, they generally employ mechanical structures to apply pressure to the leather surface for fixation. Prolonged pressure can easily cause dents on the leather surface, affecting its quality and appearance, thus reducing product quality and market competitiveness. On the other hand, traditional fixtures require the leather to provide a restraining surface, which prevents laser engraving on this surface. This limits the integrity of the engraved pattern and the flexibility of the design, failing to fully utilize the advantages of laser engraving technology and making it difficult to meet the increasingly diverse and personalized market demands.
[0004] Therefore, it is essential to invent a laser-engraved fixing fixture for translucent leather. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a translucent leather laser engraving fixing fixture, including a fixture body, a mounting plate, a micro air pump, a hose, a connector, a cavity, a positioning groove, adsorption holes, a limiting plate, and a limiting port. The mounting plate is integrally arranged below the fixture body. The micro air pump and the connector are installed on the outside of the fixture body. The micro air pump is connected to the connector through a hose. The connector is connected to the cavity inside the fixture body. The surface of the fixture body is provided with a positioning groove, and the bottom of the positioning groove is provided with a number of adsorption holes. Several limiting plates are placed inside the positioning groove, and each limiting plate is provided with a limiting port.
[0006] Preferably, the mounting plate located below the fixture body is fixedly mounted on the laser engraving machine via a connector, and the fixture body is a hollow rectangular structure.
[0007] Preferably, the inlet of the micro air pump is connected to the cavity inside the fixture body via a hose and a connector, and the micro air pump can create negative pressure in the cavity.
[0008] Preferably, the adsorption holes provided in the main body of the fixture are connected to the cavity inside itself, and some of the adsorption holes may be blocked by the limiting plate.
[0009] Preferably, the limiting plate is a rectangular plate with a rectangular limiting opening in the middle. The limiting plate is divided into a blocking plate and a positioning plate. There are several blocking plates and only one positioning plate. Each blocking plate has another blocking plate with a size matching its own limiting opening placed on its inner side, and the innermost blocking plate has a positioning plate placed on its inner side of the limiting opening.
[0010] Preferably, one of the limiting plates, i.e. the inner side of the limiting opening of the positioning plate, is used to limit the rectangular translucent leather, which is located in the center of the positioning groove.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] This invention uses a micro air pump to create negative pressure in the cavity inside the fixture body, and uses adsorption holes to adsorb leather. Compared with the traditional method of fixing leather by mechanical pressure, this avoids applying pressure to the leather for a long time, thereby effectively preventing dents from appearing on the leather surface and protecting the quality and appearance of the leather.
[0013] This utility model employs a limiting plate and a limiting opening design. The inner side of the limiting opening of the positioning plate is used to limit the rectangular translucent leather, and some of the adsorption holes can be blocked by the limiting plate. This allows for flexible adjustment of the adsorption area as needed. At the same time, it eliminates the need for the leather to have a pre-reserved limiting surface for the fixture, thereby enabling full laser engraving on the leather surface. This improves the integrity of the engraved pattern and the flexibility of the design, and can better meet personalized engraving needs.
[0014] The main body of this utility model fixture has a positioning groove on its surface. The bottom of the positioning groove is provided with numerous adsorption holes. The translucent leather is positioned by the limiting plate and the positioning plate, which can accurately restrict the leather to the center of the positioning groove, ensuring the precision of laser engraving and improving product quality and production efficiency.

[0022] As attached Figure 1 To be continued Figure 3 As shown:
[0023] This utility model provides a translucent leather laser engraving fixing fixture, including a fixture body 1, a mounting plate 2, a micro air pump 3, a hose 4, a connector 5, a cavity 6, a positioning groove 7, an adsorption hole 8, a limiting plate 9, and a limiting port 10. The mounting plate 2 is integrally arranged below the fixture body 1. The micro air pump 3 and the connector 5 are installed on the outside of the fixture body 1. The micro air pump 3 is connected to the connector 5 through the hose 4. The connector 5 is connected to the cavity 6 inside the fixture body 1. The positioning groove 7 is formed on the surface of the fixture body 1. A number of adsorption holes 8 are arranged at the bottom of the positioning groove 7. Several limiting plates 9 are placed inside the positioning groove 7. Each limiting plate 9 is provided with a limiting port 10.
[0024] Furthermore, the main body of the fixture 1 is made of aluminum alloy and has a hollow rectangular structure. This material ensures both structural strength and excellent lightweight properties. The mounting plate 2 located below the main body of the fixture 1 is fixedly mounted on the laser engraving machine using bolts and other connectors. The mounting plate 2 is firmly connected to the main body of the fixture 1 through welding, ensuring that the main body of the fixture 1 will not shift during the laser engraving process, thereby guaranteeing the accuracy of the engraving.
[0025] Furthermore, the miniature air pump 3 is a small, high-efficiency air pump. Its suction port is connected to the cavity 6 inside the fixture body 1 via a flexible rubber hose 4 and a metal connector 5. The connector 5 is threaded to the fixture body 1 and sealed with sealant to prevent air leakage. After the miniature air pump 3 is started, it can create a stable negative pressure environment in the cavity 6, providing power support for adsorbing leather.
[0026] Furthermore, the main body 1 of the fixture has numerous uniformly distributed adsorption holes 8, which are connected to the internal cavity 6. The diameter of the adsorption holes 8 is designed to be 2mm-5mm according to actual adsorption requirements. Some adsorption holes 8 can be blocked by limiting plates 9, which can be made of engineering plastic material, which has a certain degree of toughness and wear resistance. When it is necessary to adjust the adsorption area, the blocking of some adsorption holes 8 can be achieved by placing limiting plates 9 at different positions.
[0027] Furthermore, the limiting plate 9 is a rectangular plate with a rectangular limiting opening 10 in the center. The limiting plate 9 consists of a blocking plate and a positioning plate. Several blocking plates are provided, while only one positioning plate is provided. Each blocking plate and positioning plate is made of engineering plastic sheet with a thickness of 5-10 mm. Another blocking plate matching the size of its own limiting opening 10 is placed on the inner side of each blocking plate. The positioning plate is placed inside the limiting opening 10 of the innermost blocking plate, and the innermost limiting plate 9 is the positioning plate.
[0028] Furthermore, one of the limiting plates 9, namely the limiting opening 10 of the positioning plate, is used to restrict the rectangular translucent leather. The size of the limiting opening 10 of the positioning plate is designed according to the size specifications of common translucent leather to ensure that the leather can be tightly restricted. This translucent leather is located in the center of the positioning groove 7, which is opened on the surface of the fixture body 1. Its depth is 3-5 mm, and its width and length are slightly larger than the translucent leather being restricted. The edges of the positioning groove 7 are rounded to avoid scratching the leather.
[0029] The working principle is as follows: First, the mounting plate 2 below the fixture body 1 is fixedly installed to the laser engraving machine using bolts and other connecting parts. The mounting plate 2 and the fixture body 1 are firmly connected by welding process to ensure that the fixture body 1 will not be displaced during the laser engraving process, thus providing a stable foundation for subsequent precise engraving.
[0030] Next, the miniature air pump 3 is started. The suction port of the miniature air pump 3 is connected to the cavity 6 inside the fixture body 1 through a flexible rubber hose 4 and a metal connector 5. The connector 5 is threaded to the fixture body 1 and sealed with sealant to prevent air leakage. After the miniature air pump 3 starts working, it will create a stable negative pressure environment in the cavity 6.
[0031] Next, place the translucent leather. Place a rectangular piece of translucent leather into the positioning groove 7, which is formed on the surface of the fixture body 1. The groove 7 is 3-5 mm deep, slightly wider and longer than the leather being restrained, and has rounded edges to prevent scratching. The leather is then placed inside the restraining opening 10 of the positioning plate. The size of the restraining opening 10 is designed according to common translucent leather dimensions, allowing for a tight fit and ensuring the leather is centered within the positioning groove 7.
[0032] Next, adjust the adsorption area (if necessary). Since the surface of the fixture body 1 has numerous adsorption holes 8 uniformly distributed and connected to the cavity 6, with a diameter of 2mm-5mm, some adsorption holes 8 can be blocked by limiting plates 9. The limiting plates 9 are made of engineering plastic, possessing toughness and wear resistance, and consist of several blocking plates and only one positioning plate. To adjust the adsorption area, different numbers of limiting plates 9 can be placed to block some of the adsorption holes 8, thus changing the effective adsorption range.
[0033] Finally, laser engraving is performed. Under negative pressure, the adsorption holes 8 exert an adsorption force on the translucent leather, firmly fixing the leather to the fixture. At this time, the laser engraving machine starts and engraves the translucent leather. Due to the precise positioning and stable fixation of the fixture, the accuracy and quality of the laser engraved pattern are guaranteed, completing the laser engraving work on the translucent leather.
[0034] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
