[0019] See Figure 1 and Figure 2 The present invention discloses an angle-adjustable coating machine, including a coating head 1, an angle adjustment component 2, and a positioning and fixing component 3. The angle adjustment component 2 includes a handle 21, a turntable 22, and a transmission rod 23. The positioning and fixing component 3 includes a positioning plate 31, a support frame 32, a pin 33, and a spring 34. The throttle 21 is fixedly connected to one end of the transmission rod 23, and the other end of the transmission rod 23 passes through the turntable 22, the positioning plate 31 and the support frame 32 in sequence and is fixedly connected to one end of the coating head 1. The turntable 22 is fixedly connected to the transmission rod 23, the support frame 32 is fixedly connected to the positioning plate 31, and the transmission rod 23 is rotatably connected to the support frame 32 and the positioning plate 31. The positioning disk 31 is provided with a plurality of positioning holes 311 that are adapted to the pin 33, and the turntable 22 is provided with a through hole that is adapted to the pin 33. One end of the pin 33 passes through the spring 34, the through hole and the positioning hole 311 in sequence, and one end of the spring 34 is fixedly connected to the other end of the pin 33, and the other end of the spring 34 is fixedly connected to one side of the turntable 22.

[0020] In this embodiment, the operator pulls the pin 33 outward, stretching the spring 34 to disengage the pin 33 from the positioning hole 311 on the positioning disk 31, thereby releasing the lock on the turntable 22. At this time, rotating the handle 22 can drive the transmission rod 23 and the turntable 22 fixed thereto, as well as the coating head 1, to rotate synchronously, realizing continuous adjustment of the angle of the coating head 1. When the coating head 1 rotates to the required angle, a certain through hole on the turntable 22 is aligned with the corresponding positioning hole 311 on the positioning disk, the pin 33 is released, and the return of the spring 34 causes the pin 33 to re-insert into the positioning hole 311, completing precise positioning and rigid fixation. The stepless adjustment and precise positioning of the angle are achieved through a worm gear or similar transmission rod structure, which significantly improves the adaptability of the coating process to different coating thicknesses and coating characteristics, ensuring the uniformity of coating quality; and the quick-locking mechanism composed of the pin 33 and the spring 34 makes the angle adjustment operation simple and quick, and provides reliable locking force in the working state.

[0021] Optionally, the turntable 22 can be electrically connected to a PLC controller so that the rotation angle of the turntable can be controlled by the PLC controller (requiring the operator to pull up the latch).

[0022] In some embodiments, such as Figure 2 As shown, one end of the pin 33 is provided with a connecting ring 332. One side of the connecting ring 332 is fixedly connected to one end of the spring 34, and the other side of the connecting ring 332 is fixedly connected to a pull ring 333. The pull ring 333 and the connecting ring 332 facilitate quick pulling of the pin 33, and the spring 34 provides an automatic reset locking force, realizing convenient operation and reliable fixation of the locking mechanism, effectively improving the efficiency and stability of angle adjustment.

[0023] In some embodiments, such as Figure 3 As shown, the coating head 1 is connected to a U-shaped coating frame 11. Both ends of the U-shaped coating frame 11 are rotatably connected to two transmission rods 23, and one side of the U-shaped coating frame 11 is fixedly connected to the coating head 1 via a fixing post 12. The coating head 1 is supported by the U-shaped coating frame 11 and the two transmission rods 23, converting rotational motion into smooth angle adjustment, significantly improving the structural stability and balance of the coating head 1 during adjustment and operation.

[0024] In some embodiments, such as Figure 3 As shown, the support frame 32 is provided with a support rod 321, and the two ends of the support rod 321 are fixedly connected to the two sides of the support frame 32 respectively. The support rod 321 is fixed across the two sides of the support frame 32, which effectively enhances the overall structural strength and rigidity of the support frame 32 and prevents it from deforming under stress.

[0025] In some embodiments, such as Figure 1 As shown, the system also includes a frame 41, several first rotating rollers 42 and second rotating rollers 43. The first rotating rollers 42 are rotatably connected to the frame 41, and the second rotating rollers 43 are fixedly connected to the frame 41. By setting the first rotating rollers 42 and second rotating rollers 43, stable and controllable transmission of the substrate during the coating process can be achieved, ensuring the continuity and stability of the coating process. It should be understood that a turntable or positioning plate is also mounted on the frame 41, and the coating head 1 is arranged parallel to the rotating rollers.

[0026] In some embodiments, such as Figure 4 and 5As shown, it also includes a horizontal adjustment component 5, which includes a slider 51, a first drive cylinder 52, a first connecting rod 53, a bearing 54, and a slide rail 55. One side of the slide rail 55 and one end of the first drive cylinder 52 are fixedly connected to the inner side of the frame 41. The slide rail 55 is horizontally slidably connected to the slider 51. The slider 51 has a groove adapted to the bearing 54. The bearing 54 is fixedly installed in the groove and is fixedly connected to one end of the first rotating roller 42. One end of the first connecting rod 53 is fixedly connected to the output end of the first drive cylinder 52, and the other end of the first connecting rod 53 is fixedly connected to the slider 551. The driving direction of the first drive cylinder 52 is parallel to the sliding direction of the slider 51.

[0027] In this embodiment, the first drive cylinder 52 can be a pneumatic cylinder or a hydraulic cylinder, etc. The first drive cylinder 52 serves as a power source, and its output end pushes or pulls the slider 51 via the first connecting rod 53, causing it to slide precisely horizontally along the slide rail 55 fixed on the frame 41. Since the slider 51 is connected to the end of the first rotating roller 42 via the bearing 54 in the groove, the linear motion of the slider is directly converted into the horizontal displacement of the axis of the first rotating roller 42. In this embodiment, the horizontal adjustment component 5 integrates mechanical transmission and hydraulic / pneumatic drive to achieve horizontal position adjustment of the first rotating roller 42 in the coating system. It is understood that horizontal adjustment components 5 can be provided at both ends of the first rotating roller 42.

[0028] In some embodiments, the slide rail 55 includes an upper slide rail and a lower slide rail, and the slider 51 is provided with an upper sliding groove and a lower sliding groove. The upper slide rail is slidably connected to the upper sliding groove, and the lower slide rail is slidably connected to the lower sliding groove. By cooperating with the corresponding sliding grooves on the slider, the slider is firmly constrained on the horizontal sliding trajectory, enhancing the rigidity and stability of the slider during movement and effectively preventing jamming, warping, or deviation.

[0029] In some embodiments, such as Figure 4 As shown, it also includes a vertical adjustment component 6, which includes a second drive cylinder 61 and a connecting plate 62. The connecting plate 62 is provided on the inner side of the frame 41. One end of the second drive cylinder 61 is fixedly connected to the connecting plate 62, the output end of the second drive cylinder 61 is fixedly connected to one end of the connecting plate 62, and the other end of the connecting plate 62 is fixedly connected to the second rotating roller 43.

[0030] In this embodiment, the connecting plate 62 is directly driven by the second drive cylinder 61, which in turn drives the second rotating roller 43 fixed thereto to move vertically. The vertical adjustment component 6 efficiently converts the linear output of the drive source into the lifting motion of the roller, realizing rapid and stable adjustment of the height of the second rotating roller 43. This allows for flexible control of the wrap angle and tension of the substrate, effectively compensating for thickness variations caused by different processes or materials.

[0031] In some embodiments, the second rotating roller 43 includes a fixed rod 431 and a rotating ring 432, the fixed rod 431 being rotatably connected to the rotating ring 432, and both ends of the fixed rod 431 being fixedly connected to the two connecting plates 62 respectively. The fixed rod 431 provides a rigid connection, and the rotating ring 432 rotates flexibly around it.

[0032] In some embodiments, such as Figure 4 or Figure 6 As shown, it also includes a take-up roller 7 and a fixing assembly 8. The two ends of the take-up roller 7 are rotatably connected to the frame 41, and one end of the take-up roller 7 is provided with a gear 71, which is connected to the drive component for transmission. The fixing assembly 8 includes a third drive cylinder 81, a second connecting rod 82 and a fixing block 83. The third drive cylinder 81 is fixedly connected to the inner side of the frame 41. The output end of the third drive cylinder 81 is rotatably connected to one end of the second connecting rod 82, and the other end of the second connecting rod 82 is rotatably connected to the fixing block 83. The fixing block 83 is provided with an arc-shaped notch adapted to the take-up roller 7.

[0033] In this embodiment, the third drive cylinder 81 serves as the power source, and the extension and retraction of its piston rod is converted into the arc trajectory motion of the fixed block 83 via the second connecting rod 82. When the third drive cylinder 81 pushes, the second connecting rod 82 drives the fixed block 83 to swing towards the journal of the take-up roller 7, causing its arc-shaped notch to tightly fit and hug the journal, thereby forming a rigid constraint in the radial direction to prevent jumping or displacement during the winding process. When it is necessary to change the roll, the third drive cylinder 81 pulls in the opposite direction, which allows the fixed block 83 to quickly disengage and release the take-up roller 7. The rigid mechanical locking effectively suppresses the vibration and sway that may occur during high-speed winding, ensuring the uniformity of winding tension and the neatness of the roll material, ultimately improving the quality of the finished product.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
