Detailed Implementation
[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0030] In this embodiment, refer to Figure 1 - Figure 11The present invention relates to a novel material knurling machine, comprising an outer frame 1, and a knurling module and a feeding module disposed on the outer frame 1, wherein the feeding module comprises a connecting component and a pressing component.
[0031] The connecting assembly includes a receiving frame 2 that can swing along one end and a connecting member 3 that can be telescopically mounted on the receiving frame 2. The receiving frame 2 is provided with a slide rail 4 that restricts the connecting member 3. The bottom of the receiving frame 2 is provided with a first cylinder 11 for pushing the connecting member 3 to perform telescopic movement. The outer frame 1 is provided with a hydraulic cylinder 10 for pushing the receiving frame 2 to swing along one end.
[0032] The pressing assembly includes a pressing frame 5 that can swing along one end and a drive roller 6 disposed on the pressing frame 5. The outer frame 1 is provided with a second cylinder 12 for pushing the pressing frame 5 to swing along one end. The drive roller 6 and the connecting member 3 are disposed opposite to each other. The pressing frame 5 is provided with a reduction motor 16 for driving the drive roller 6 to rotate.
[0033] The connecting assembly and the pressing assembly constitute a feeding module for guiding and receiving external roll material. Specifically, the retractable connecting member 3 on the receiving frame 2 moves outward to connect with the external roll material, and the pressing frame 5 drives the drive roller 6 to swing towards the connecting member 3. The drive roller 6 and the connecting member 3 clamp and fix the roll material relative to each other, and the reduction motor 16 drives the drive roller 6 to rotate, thereby conveying the roll material into the knurling module, thus completing the material feeding and conveying process.
[0034] The feeding module also includes a first roller 21 and a second roller 22. The first roller 21 is installed on the opposite side of the second roller 22 via a lifting mechanism. Before being conveyed to the knurling module, the rolled material needs to be rolled by the first roller 21 and the second roller 22 to ensure the flatness and positioning accuracy of the rolled material. One end of the receiving frame 2 swings along the center of the second roller 22 to guide the rolled material between the first roller 21 and the second roller 22.
[0035] The distance between the first roller 21 and the second roller 22 is adjusted via a lifting mechanism. In practical applications, the distance between the first roller 21 and the second roller 22 needs to be adjusted according to the thickness of the rolled material to ensure that the contact pressure between the first roller 21 and the rolled material is moderate, avoiding damage to the rolled material or unstable conveying, thus adapting to the production needs of various specifications. After the rolled material is rolled by the first roller 21 and the second roller 22, it will be smoothly guided to the knurling module, providing a good foundation for subsequent knurling processing. The lifting mechanism includes a lifting frame 7 for mounting the first roller 21 and a third cylinder 13 for driving the lifting frame 7 to move up and down. Driven by the third cylinder 13, the distance between the first roller 21 and the second roller 22 is adjusted. The stroke of the third cylinder 13 can be preset according to the thickness of the rolled material to ensure close contact between the first roller 21 and the rolled material, improving the rolling effect.
[0036] The material knurling machine in this embodiment also includes a drive module, which includes a drive motor 15 and a gearbox 17. The output end of the gearbox 17 is connected to the first knurling shaft 31, the second knurling shaft 32, the first roller 21, and the second roller 22 via corresponding universal couplings 18. The output end of the drive motor 15 is connected to the input end of the gearbox 17. The drive motor 15, utilizing the combination structure of the gearbox 17 and multiple universal couplings 18, synchronously drives the first knurling shaft 31, the second knurling shaft 32, the first roller 21, and the second roller 22 to rotate, ensuring the stability and continuity of the rolled material during the conveying process.
[0037] The gearbox 17 contains a main drive gear 19, two first driven gears 23, and two second driven gears 24. The main drive gear 19 is connected to the output of the drive motor 15. The main drive gear 19 is connected to the first driven gears 23 and the second driven gears 24 via two auxiliary drive gears 20. The two second driven gears 24 mesh with each other and are connected to the first knurled shaft 31 and the second knurled shaft 32 via corresponding universal couplings 18. The two first driven gears 23 mesh with each other and are connected to the first roller 21 and the second roller 22 via corresponding universal couplings 18. This ensures that the power of the drive motor 15 is evenly distributed to each roller, guaranteeing the consistency of rotational speed and torque of each roller and preventing damage to the rolled material or unstable conveying due to uneven speed or excessive torque. Simultaneously, the use of universal couplings 18 increases the flexibility and reliability of the transmission system, enabling it to adapt to minor deviations and vibrations under different working conditions, ensuring transmission efficiency and service life.
[0038] The knurling module includes a knurling frame 30, a first knurling shaft 31, and a second knurling shaft 32. The second knurling shaft 32 is rotatably mounted on the knurling frame 30. The first knurling shaft 31 is mounted on the opposite side of the second knurling shaft 32 via an adjusting assembly. The adjusting assembly includes a fixing bracket 14 for mounting the first knurling shaft 31, a screw mechanism 8 for driving the fixing bracket 14 to move, and a driving member 25 for driving the screw mechanism 8 to rotate. The driving member 25 controls the rotation of the screw mechanism 8 to achieve relative movement of the first knurling shaft 31 relative to itself, thereby precisely adjusting the spacing between the two knurling shafts and ensuring the consistency of the knurling depth and pattern.
[0039] In this embodiment, the drive component 25 adopts a knob-type handle design, which is easy to operate and allows workers to quickly adjust the knurling shaft spacing according to actual needs, thereby improving production efficiency.
[0040] Alternatively, a servo motor can be used as the drive component 25. This allows for precise adjustment of the rotation angle and speed of the screw mechanism 8 via servo control, enabling fine-tuning of the first knurling shaft 31 and further improving knurling quality and efficiency. The high responsiveness and stability of the servo motor ensure precise control of the knurling process, reducing errors and inconvenience caused by manual adjustment.
[0041] The surfaces of the first knurling shaft 31 and the second knurling shaft 32 can be customized with different knurling patterns according to the actual needs of the product.
[0042] The screw mechanism 8 includes a drive rod 803 and a lifting screw 802. The lifting screw 802 is rotatably mounted on the knurling frame 30 via a first bushing 801. One end of the lifting screw 802 is connected to the fixed frame 14. The drive component 25 is mounted on one end of the drive rod 803. The drive rod 803 drives the lifting screw 802 to rotate via a first gear, thereby causing the fixed frame 14 to move axially. This precisely adjusts the distance between the first knurling shaft 31 and the second knurling shaft 32, ensuring the uniformity and stability of the knurling effect and improving product quality.
[0043] Furthermore, both ends of the knurling frame 30 are equipped with fine-tuning mechanisms 9. Each fine-tuning mechanism 9 includes a locking screw 901 and a drive handle 903. The locking screw 901 is rotatably mounted on the knurling frame 30 via a second bushing 902. The drive handle 903 drives the locking screw 901 to rotate via a second gear, causing one end of the locking screw 901 to abut against the fixing frame 14. This applies pressure to the fixing frame 14 and the first knurling shaft 31 through the locking screw 901, thereby achieving fine-tuning of the distance between the two shafts. This effectively ensures the knurling accuracy and pattern consistency, improving the overall aesthetics and performance of the product. Both the first and second gears are helical gears.
[0044] Furthermore, measuring instruments 26 are correspondingly provided on both sides of the knurled frame 30 for cooperating with the fixing frame 14. The fine-tuning mechanisms 9 arranged at both ends of the knurled frame 30 rely on the corresponding measuring instruments 26 to accurately measure the actual distance between the two axes, ensuring that the adjustment data is accurate. In this embodiment, the measuring instrument 26 is a dial indicator. Through the high-precision reading of the dial indicator, the distance change is fed back in real time, further optimizing the knurling process, ensuring that each adjustment achieves the expected effect, and improving the product qualification rate.
[0045] Furthermore, the measuring instrument 26 can also be replaced with a laser rangefinder. Utilizing the high-precision ranging capability of lasers, it can monitor distance changes in real time and synchronize this information to the control system for automated adjustment, reducing manual intervention and improving production efficiency and accuracy. The rapid response and precision of the laser rangefinder ensure the efficiency and stability of the knurling process, further enhancing product quality and consistency.
[0046] In this embodiment, the material knurling machine also includes a correction module located at both ends of the knurling module. The correction module includes a correction frame 27, a bidirectional screw 28, a support roller 29 flexibly mounted on the correction frame 27, and two sets of limiting rollers 33 symmetrically mounted on the bidirectional screw 28. Each set of limiting rollers 33 consists of two rotatable correction rollers symmetrically positioned on both sides of the support roller 29. The correction module drives the bidirectional screw 28 to rotate, thereby adjusting the distance between the two sets of limiting rollers 33. This achieves precise positioning of the material during the knurling process, preventing deviation and ensuring the symmetry and uniformity of the knurling pattern, further improving the overall product quality. Furthermore, the design combining the flexible support roller 29 with the limiting rollers 33 allows for material correction while also adapting to materials of different thicknesses, ensuring consistent knurling results.
[0047] In this embodiment, the material feeding knurling machine is provided with a transition guide frame 34 between the correction module and the second knurling shaft 32 and between the correction module and the second roller 22. The transition guide frame 34 is provided with a guide roller 35 for guiding the material.
[0048] The end of the knurling module is equipped with a discharge roller 36, which is used to smoothly output the knurled roll material. The surface of the discharge roller 36 is provided with anti-slip texture to increase the friction between the roller and the roll material, prevent slippage or deviation during the output process, and ensure the stability and accuracy of the roll material.
[0049] This invention utilizes a feeding module comprised of a connecting assembly and a pressing assembly to achieve automatic material introduction and stable pressing. The retractable and swingable design of the receiving rack 2 and the connecting piece 3 allows for smooth material transfer to the knurling module. Simultaneously, the drive roller 6 on the pressing rack 5 moves the material, ensuring stability and continuity during the knurling process, significantly improving embossing efficiency and effect. Furthermore, a dial indicator is used to monitor the knurling shaft spacing in real time, ensuring the accuracy and consistency of the knurling pattern. Additionally, the gearbox 17 and universal coupling 18 structure enable synchronous rotation of the feeding and knurling shafts, ensuring smooth transport of the rolled material during processing.
