Description

Technical Field

[0001] This utility model relates to the field of leather embossing technology, and in particular to a leather embossing device for leather processing. Background Technology

[0002] Leather embossing is a technique that uses specific equipment and processes to create various patterns, designs, or three-dimensional effects on the surface of leather. For example, embossing machines use rollers to press patterns onto leather. However, in actual embossing work, we have found that the patterns on the embossing rollers cannot be changed or adjusted according to different embossing requirements. The patterns on the rollers are engraved and raised, and they are an integral part of the rollers. This imposes many limitations on leather embossing. Even if the pattern is changed, the entire roller must be replaced. Consequently, other types of rollers need to be produced for adjustment and replacement, which increases costs.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0004] This utility model proposes a leather embossing device for leather processing, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: A leather embossing device for leather processing includes a frame. A stepper motor is fixedly installed on one side of the frame. The output shaft of the stepper motor passes through the interior of the frame and is fixedly installed with an embossing roller. The end of the embossing roller away from the stepper motor is rotatably mounted on the inner wall of the frame. A threaded post is fixedly connected to one side of the inner cavity of the embossing roller. A threaded end is fixedly connected to one end of the threaded post. Four openings are provided on the surface of the embossing roller. Four embossing pieces are threadedly installed on the surface of the threaded post. The openings are adapted to the embossing pieces. A retaining ring is threadedly installed on the threaded end.

[0006] The leather embossing device for leather processing described above further includes: a support plate located below the embossing roller is provided inside the frame, and a threaded rod is fixedly connected to the bottom of the support plate, with the bottom end of the threaded rod extending through to the bottom of the frame.

[0007] The leather embossing device for leather processing described above further includes: a base plate fixedly installed at the bottom of the frame, and the bottom of the threaded rod extending through to the bottom of the base plate.

[0008] The leather embossing device for leather processing described above further includes: two locking nuts threaded onto the surface of the threaded rod, with the two locking nuts located above and below the base plate, respectively.

[0009] The leather embossing device for leather processing described above further includes: an elongated hole at one end of each side of the frame, bearings slidably installed inside the two elongated holes, and a flattening roller located inside the frame fixedly installed inside the bearings.

[0010] The leather embossing device for leather processing described above further includes: an adjusting screw that is provided through one side of the inner cavity of the elongated hole; one end of the adjusting screw is rotatably mounted on a bearing; and the other end of the adjusting screw extends through to the outside of the frame.

[0011] The leather embossing device for leather processing described above further includes: both ends of the top side of the frame are fixedly connected to brackets, one side of which is detachably mounted with a mounting rod, and a take-up roller is rotatably mounted on the top of the mounting rod.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model adopts the principle of retaining the main body of the pressure roller, and only disassembling and replacing the corresponding pattern pieces according to different embossing requirements, so as to achieve the effect of changing different embossing patterns. In this way, there is no need to increase the number of other pressure rollers, reducing the cost of leather embossing processing, improving the efficiency of leather embossing work, and providing convenience for users.

[0014] 2. This utility model, through the arrangement of a threaded rod, a support plate, locking nuts, and a base plate, allows the support plate to adjust its height according to the thickness of the leather. During adjustment, the two locking nuts are rotated upwards or downwards. When the two locking nuts are adjusted upwards, the support plate moves up or down on the base plate under their action, and the corresponding locking nuts abut against the base plate, thus positioning the support plate at the current height. Conversely, when the support plate is rotated downwards, it moves up on the base plate, and the corresponding locking nuts abut against the base plate, positioning the support plate at the current height. This satisfies the processing needs of leathers of different thicknesses. When the embossing roller embosses the leather, the support plate provides a reaction force by lifting the leather. Furthermore, the embossing depth can be adjusted by changing the height of the support plate, meeting different embossing requirements and providing convenience for users.

[0015] 3. This utility model, through the arrangement of an elongated hole, bearing, flattening roller, and adjusting screw, uses the flattening roller to flatten the leather and prevent the leather from curling up at the beginning after being fed out from one side of the embossing roller. The working position of the flattening roller can also be adjusted. The adjusting screw is threaded on the frame, and its end is rotatably mounted on the bearing. Thus, when the adjusting screw is rotated counterclockwise, it moves outward from the frame, thereby pulling the bearing and flattening roller away from the embossing roller. Conversely, when the adjusting screw is rotated clockwise, it pushes the bearing and flattening roller closer to the embossing roller, thereby meeting the working requirements of leather embossing and providing convenience for users.

[0016] 4. This utility model, through the setting of a bracket, mounting rod and winding roller, the winding roller is used to wind up leather. According to the actual work requirements, a drive motor can be installed on one side of the mounting rod and connected to the winding roller. The drive motor drives the winding roller to rotate and wind up the leather, providing convenience for the user's work. Attached Figure Description

[0023] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0024] A leather embossing device for leather processing includes a frame 1. A stepper motor 2 is fixedly installed on one side of the frame 1. The output shaft of the stepper motor 2 passes through the interior of the frame 1 and is fixedly installed on an embossing roller 3. The end of the embossing roller 3 away from the stepper motor 2 is rotatably mounted on the inner wall of the frame 1. A threaded post 4 is fixedly connected to one side of the inner cavity of the embossing roller 3. A threaded end 6 is fixedly connected to one end of the threaded post 4. Four openings 5 ​​are provided on the surface of the embossing roller 3. Four embossing pieces 7 are threadedly installed on the surface of the threaded post 4. The openings 5 ​​are adapted to the embossing pieces 7. A retaining ring 8 is threadedly installed on the surface of the threaded end 6.

[0025] The specific working process is as follows: First, remove the embossing roller 3 from the frame 1 and separate the embossing roller 3 from the stepper motor 2. Then, move the embossing roller 3 to the worktable or place it in a suitable location for disassembly. During disassembly, first loosen and remove the retaining ring 8 from the threaded end 6 inside the embossing roller 3. Then, loosen and remove all the embossing pieces 7 from the 419 inside the embossing roller 3 in sequence. At the same time, the protruding parts on the embossing pieces 7 used for engraving the printing pattern will also move out from the corresponding opening 5. In this way, all the embossing pieces 7 can be removed from the embossing roller 3, and the disassembly of the roller can be completed quickly. Then, according to the actual processing requirements, install the required number of embossing pieces 7 onto the threaded post 4 using a threaded connection. It should be noted that multiple embossing pieces 7 can be set with different pattern styles, so that different patterns can be printed simultaneously. In the processing, when multiple embossing pieces 7 have the same pattern, it is possible to simultaneously emboss multiple quantities of leather, thus increasing the embossing speed, production progress, and efficiency of leather embossing. This provides convenience for users, meets their different work needs, and offers more flexible operation options for embossing work. After the corresponding embossing piece 7 is installed on the threaded post 4, the end of the embossing roller 3 is sealed with a retaining ring 8 to prevent the embossing piece 7 from falling off. When installing the embossing piece 7, the protruding printed part on the embossing piece 7 should be inserted into the corresponding opening 5. This opening 5 restricts the free movement of the embossing piece 7, ensuring the stability of the embossing piece 7 during embossing work, improving the accuracy and quality of leather embossing, and reducing the defect rate of leather embossing.To reduce material consumption and lower costs, the embossing roller 3 is then reinstalled onto the frame 1, and connected to the stepper motor 2. The stepper motor 2 is then started, driving the embossing roller 3 to rotate within the frame 1. This embossing process is applied to the leather passing below the embossing roller 3 and above the tray 10. The embossed leather is then wound up by the take-up roller 19, which also pulls on the leather. Simultaneously, the rotation of the embossing roller 3 pushes the leather, preventing it from clogging within the frame 1 and ensuring the normal operation of the leather embossing process. It should be noted that the tray 10 can also be height-adjusted according to the leather thickness. Adjustment is achieved by rotating the two locking nuts 11 upwards or downwards. When the two locking nuts 11 are adjusted upwards, the tray 10 moves up and down on the base plate 12 under the action of the locking nuts 11, and the corresponding locking... The locking nut 11 abuts against the base plate 12, thus positioning the support plate 10 at its current height. Conversely, the support plate 10 moves upward on the base plate 12, and the corresponding locking nut 11 also abuts against the base plate 12, positioning the support plate 10 at its current height. This satisfies the processing needs of leathers of different thicknesses. When the embossing roller 3 embosses the leather, the support plate 10 lifts the leather and provides a reaction force. At the same time, the embossing depth of the leather can be adjusted by adjusting the height of the support plate 10, meeting different embossing needs and providing convenience for users. Therefore, by retaining the main body of the pressure roller and only disassembling and replacing the corresponding pattern pieces according to different embossing needs, different embossing patterns can be changed. This eliminates the need to increase the number of other pressure rollers, reduces the cost of leather embossing, improves the efficiency of leather embossing, and provides convenience for users.

[0026] The frame 1 has a support plate 10 located below the embossing roller 3 inside. A threaded rod 9 is fixedly connected to the bottom of the support plate 10. The bottom end of the threaded rod 9 extends through to the bottom of the frame 1. A base plate 12 is fixedly installed at the bottom of the frame 1. The bottom of the threaded rod 9 extends through to the bottom of the base plate 12. Two locking nuts 11 are threadedly installed on the surface of the threaded rod 9. The two locking nuts 11 are located above and below the base plate 12, respectively.

[0027] Specifically, the threaded rod 9, support plate 10, locking nut 11, and base plate 12 are configured such that the support plate 10 can be adjusted in height according to the thickness of the leather. During adjustment, the two locking nuts 11 are rotated up or down. When the two locking nuts 11 are adjusted upwards, the support plate 10 will move up or down on the base plate 12 under the action of the locking nuts 11, and the corresponding locking nuts 11 will abut against the base plate 12, thereby positioning the support plate 10 at the current height. Conversely, the support plate 10 will move upwards on the base plate 12, and the corresponding locking nuts 11 will also abut against the base plate 12, positioning the support plate 10 at the current height. This meets the processing needs of leathers of different thicknesses. When the embossing roller 3 embosses the leather, the support plate 10 lifts the leather and provides a reaction force. At the same time, the embossing depth of the leather can be adjusted by adjusting the height of the support plate 10 to meet different embossing needs of the leather and provide convenience for users' work.

[0028] Each of the two sides of the frame 1 has an elongated hole 13 at one end. A bearing 14 is slidably installed inside the two elongated holes 13. A flattening roller 15 located inside the inner side of the frame 1 is fixedly installed inside the bearing 14. An adjusting screw 16 is provided through one side of the inner cavity of the elongated hole 13. One end of the adjusting screw 16 is rotatably installed on the bearing 14, and the other end of the adjusting screw 16 extends to the outer side of the frame 1.

[0029] Specifically, the oblong hole 13, bearing 14, pressing roller 15, and adjusting screw 16 are arranged as follows: the pressing roller 15 is used to flatten the leather and prevent the leather from curling up at the beginning after being fed out from one side of the embossing roller 3. The working position of the pressing roller 15 can also be adjusted. The adjusting screw 16 is threaded on the frame 1, and its end is rotatably mounted on the bearing 14. When the adjusting screw 16 is rotated counterclockwise, it will move outward from the frame 1, thereby pulling the bearing 14 and the pressing roller 15 away from the embossing roller 3. Conversely, when the adjusting screw 16 is rotated clockwise, it will push the bearing 14 and the pressing roller 15 closer to the embossing roller 3, thus meeting the working requirements of leather embossing and providing convenience for users.

[0030] Both ends of the top side of the frame 1 are fixedly connected to brackets 17. One side of one bracket 17 is detachably mounted with a mounting rod 18. A take-up roller 19 is rotatably mounted on the top of the side of the mounting rod 18.

[0031] Specifically, the bracket 17, mounting rod 18, and take-up roller 19 are configured. The take-up roller 19 is used to take up leather. According to actual work needs, a drive motor can be installed on one side of the mounting rod 18 and connected to the take-up roller 19. The drive motor drives the take-up roller 19 to rotate and take up the leather, providing convenience for the user's work.

[0032] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
