Description

Technical Field

[0001] This utility model relates to the technical field of leather production equipment, specifically to an embossing machine for leather production and processing. Background Technology

[0002] Leather is animal hide that has undergone physical and chemical processing, possessing excellent physical and mechanical properties, comfort, and degradation stability. Leather can be broadly classified into two categories: genuine leather and synthetic leather.

[0003] Leather is made of natural protein fibers tightly woven in three dimensions. Its surface has a special grain layer, giving it a natural texture and luster, and a comfortable feel. It is one of the main materials for making clothing and footwear.

[0004] To enhance the aesthetics of leather, embossing machines are typically used in the production of artificial leather. However, traditional embossing devices cannot perform embossing of various groove shapes; they can only emboss a single shape, which limits their application and fails to meet the actual production requirements of different patterns. Their structural applicability is also poor, making it difficult to meet the diverse embossing needs of modern leather production. Therefore, this invention proposes an embossing machine for multi-style leather production that can convert embossing shapes. Utility Model Content

[0005] The purpose of this utility model is to provide an embossing machine for leather production and processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an embossing machine for leather production and processing, comprising an embossing base, an embossing machine frame fixedly mounted on the upper surface of the embossing base, a connecting horizontal plate fixedly mounted on the top of the embossing machine frame by welding, an embossing cylinder fixedly mounted on the center position of the upper surface of the connecting horizontal plate by bolts, a hydraulic rod telescopically connected to the output end of the embossing cylinder, a motor frame fixedly mounted on the bottom end of the hydraulic rod, the motor frame adopting a square hollow structure design, a primary conversion motor fixedly mounted inside the motor frame by fixing bolts, a convex head turntable fixedly mounted on the bottom end of the output shaft of the primary conversion motor, a plurality of embossing protrusions fixedly mounted on the lower surface of the convex head turntable, the plurality of embossing protrusions being circumferentially distributed at equal intervals around the center point of the convex head turntable, and each embossing protrusion having a different shape.

[0007] Preferably, the embossing base has a hollow structure design, and a two-stage conversion motor is fixedly installed on one side of the embossing base by bolts.

[0008] Preferably, the output shaft of the secondary conversion motor is fixedly mounted with a drive gear, and a driven gear is meshed with one side of the drive gear and inside the embossing base.

[0009] Preferably, a connecting shaft is fixedly installed at the center of the upper surface of the driven gear, and the top end of the connecting shaft protrudes from the upper surface of the embossed base and is fixedly connected to a grooved turntable.

[0010] Preferably, the grooved turntable has a plurality of embossing grooves, which are circumferentially distributed at equal intervals around the center point of the grooved turntable.

[0011] Preferably, the number of embossing grooves is the same as the number of embossing protrusions, and the shapes of the embossing grooves correspond one-to-one with the shapes of the embossing protrusions.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The embossing protrusion of this utility model can be lowered under the driving action of the hydraulic cylinder. The lowered embossing protrusion can cooperate with the corresponding embossing groove on the grooved turntable for embossing, thereby embossing the leather between the grooved turntable and the protrusion turntable, ensuring the normal embossing operation of the embossing machine of this utility model.

[0014] This invention features several embossing grooves and embossing protrusions of different shapes on a grooved turntable and a protruding turntable. These grooves and protrusions can be rotated and repositioned by two switching motors, allowing different embossing structures to be rotated and positioned at the embossing station. In practical use, it can complete embossing work on leather of different shapes. Compared to traditional single-shape embossing devices, this embossing machine can handle embossing of leather of different shapes, effectively improving the processing diversity of embossing shapes and meeting the production and processing needs of different pattern pressing. The machine has wider applicability, effectively reducing the limitations of traditional machines. Furthermore, the overall machine structure is simple, with low manufacturing and maintenance costs, making it suitable for implementation. Attached Figure Description

[0023] Please see Figure 1-4 An embodiment of this utility model is provided: an embossing machine for leather production and processing, including an embossing base 1, and an embossing machine frame 2 fixedly installed on the upper surface of the embossing base 1;

[0024] Please refer to the instruction manual for details. Figure 2 as well as Figure 3 As shown, a connecting horizontal plate 3 is fixedly installed at the top of the embossing machine frame 2 by welding. An embossing cylinder 4 is fixedly installed at the center of the upper surface of the connecting horizontal plate 3 by bolts. A hydraulic rod 5 is telescopically connected to the output end of the embossing cylinder 4. A motor frame 6 is fixedly installed at the bottom end of the hydraulic rod 5.

[0025] The hydraulic cylinder 4 can drive the hydraulic rod 5 to extend and retract. When the hydraulic rod 5 extends, it will drive the motor frame 6 at the bottom to descend. The descent of the motor frame 6 can drive the entire structure to be lowered, providing displacement conditions for subsequent leather embossing.

[0026] Furthermore, the motor frame 6 adopts a square hollow structure design. The first-stage conversion motor 7 is fixedly installed inside the motor frame 6 by fixing bolts. The bottom end of the output shaft of the first-stage conversion motor 7 is fixedly installed with a convex head turntable 8. Several embossed convex heads 9 are fixedly installed on the lower surface of the convex head turntable 8. The several embossed convex heads 9 are evenly distributed circumferentially through the center point of the convex head turntable 8, and the shape of each embossed convex head 9 is different.

[0027] With this structural design, when the motor frame 6 descends under the action of the embossing cylinder 4 and the hydraulic rod 5, it will drive the bottom convex turntable 8 to descend synchronously. When the convex turntable 8 descends, the embossing convex head 9 can descend synchronously, so that the embossing convex head 9 can emboss the leather below.

[0028] Meanwhile, this utility model has several embossing protrusions 9 of different shapes set on the convex turntable 8. When it is necessary to change the embossing shape of the leather, it can be operated by the set primary conversion motor 7. When the primary conversion motor 7 is working, it drives the convex turntable 8 to rotate a certain angle through its output shaft. When the convex turntable 8 rotates, the several embossing protrusions 9 below it will be converted, so that another shape of embossing protrusion 9 can be converted to the embossing position, thereby pressing out different shapes of patterns on the leather and ensuring the diversity of leather embossing.

[0029] In this embodiment, to adapt to the embossing protrusion 9 for leather embossing, please refer to the attached instruction manual for details. Figure 1 as well as Figure 4 As shown, the embossing base 1 has a hollow structure. A two-stage conversion motor 10 is fixedly installed on one side of the embossing base 1 by bolts. A drive gear 11 is fixedly installed on the output shaft of the two-stage conversion motor 10. A driven gear 12 is meshed with one side of the drive gear 11 and inside the embossing base 1. The two-stage conversion motor 10 can drive the drive gear 11 to rotate through its output shaft. In this way, the rotation of the drive gear 11 can drive the driven gear 12, which is meshed with on the side, to rotate synchronously.

[0030] Furthermore, a connecting shaft is fixedly installed at the center of the upper surface of the driven gear 12, and the top end of the connecting shaft protrudes through the upper surface of the embossed base 1 and is fixedly connected to a grooved turntable 13.

[0031] Furthermore, the grooved turntable 13 is provided with a plurality of embossed grooves 14, which are distributed circumferentially at equal intervals around the center point of the grooved turntable 13.

[0032] In this structural design, when the driven gear 12 rotates under the action of the secondary conversion motor 10 and the driving gear 11, it will drive the groove turntable 13 to rotate synchronously through the connecting shaft. In this way, the rotation of the groove turntable 13 drives the embossing groove 14 to rotate and change position, so that the embossing groove 14 that is adapted to the embossing protrusion 9 can be rotated to the bottom of the corresponding protrusion, which meets the requirements of the adapted leather embossing.

[0033] In this embodiment, in order to adapt to the shape and number of embossed protrusions 9, the number of embossed grooves 14 is the same as the number of embossed protrusions 9, and the shape of several embossed grooves 14 corresponds one-to-one with the shape of several embossed protrusions 9.

[0034] Working principle: When using this utility model, the leather to be embossed is placed on the grooved turntable 13, at which time the embossed leather is placed between the grooved turntable 13 and the convex turntable 8;

[0035] Then, the embossing cylinder 4 is activated. The embossing cylinder 4 can drive the hydraulic rod 5 to extend and retract. When the hydraulic rod 5 extends, it will drive the motor frame 6 at the bottom to descend.

[0036] When the motor frame 6 descends under the action of the embossing cylinder 4 and the hydraulic rod 5, it will drive the bottom convex turntable 8 to descend synchronously. When the convex turntable 8 descends, the embossing convex head 9 can descend synchronously. In this way, the descending embossing convex head 9 can cooperate with the corresponding embossing groove 14 on the groove turntable 13 to emboss, so as to emboss the leather between the groove turntable 13 and the convex turntable 8, ensuring the normal embossing operation of the embossing machine of this utility model.

[0037] If it is necessary to change the embossing shape of the leather, the hydraulic cylinder 4 drives the hydraulic rod 5 to retract one end distance. When the hydraulic rod 5 retracts, it can simultaneously drive the convex turntable 8 to rise one end distance.

[0038] During the displacement upward process, the set first-level conversion motor 7 can work. When the first-level conversion motor 7 works, it drives the convex head turntable 8 to rotate a certain angle through its output shaft. When the convex head turntable 8 rotates, several embossing convex heads 9 below it will be converted, so that another shape of embossing convex head 9 can be converted to the embossing position.

[0039] During the embossing shape conversion process of the primary conversion motor 7, the secondary conversion motor 10 inside the embossing base 1 can rotate synchronously. The secondary conversion motor 10 can drive the drive gear 11 to rotate through its output shaft. In this way, the rotation of the drive gear 11 can drive the driven gear 12, which is meshed with the side, to rotate synchronously.

[0040] When the driven gear 12 rotates under the action of the secondary conversion motor 10 and the driving gear 11, it will drive the groove turntable 13 to rotate synchronously through the connecting shaft. In this way, the rotation of the groove turntable 13 drives the embossing groove 14 to rotate and change position, so that the embossing groove 14 that is adapted to the embossing protrusion 9 can be rotated to the bottom of the corresponding protrusion, which satisfies the use of the adapted leather embossing.

[0041] After the embossing protrusion 9 and embossing groove 14 are converted, the leather can be placed back onto the groove turntable 13 and the protrusion turntable 8. The embossing cylinder 4 drives the embossing protrusion 9 to descend through the hydraulic rod 5 to perform embossing treatment, thereby completing the embossing production of leather in different shapes.

[0042] Based on the above structure, the embossing protrusion 9 of this utility model can be lowered under the driving action of the oil cylinder. The lowered embossing protrusion 9 can cooperate with the corresponding embossing groove 14 on the groove turntable 13 for embossing, thereby embossing the leather between the groove turntable 13 and the protrusion turntable 8, ensuring the normal embossing operation of the embossing machine of this utility model.

[0043] This invention features several embossing grooves 14 and embossing protrusions 9 of different shapes, respectively, on the grooved turntable 13 and the protruding turntable 8. The embossing grooves 14 and embossing protrusions 9 can be rotated and repositioned under the action of two conversion motors, thereby rotating and repositioning embossing structures of different shapes to the embossing station. In actual use, it can complete the embossing work of different shapes of leather. Compared with the traditional single-shape embossing device, the embossing machine of this invention can meet the embossing processing of leather of different shapes, effectively improving the processing diversity of embossing shapes, meeting the production and processing needs of different pattern pressing, and making the machine more widely applicable. It effectively reduces the limitations of traditional machines, and the overall machine structure is simple, with low manufacturing and maintenance costs, making it suitable for implementation.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
