Detailed Implementation

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 5 As shown, this utility model provides a high-precision adjustable coating machine, including a machine body 1, a guide mechanism 2, a coating mechanism 3, and a scraper mechanism 4, all disposed on the machine body 1. The guide mechanism 2 is used to guide the film material through the coating mechanism 3, the coating mechanism 3 is used to coat the film material, and the scraper mechanism 4 is used to scrape off the corresponding coating material on the coating mechanism 3 before coating. The scraper mechanism 4 includes an adjustable base 41, a scraper 42, an adjustable mechanism 43, a limiting base 44, and a limiting screw 45. The adjustable base 41 is slidably disposed on the machine body 1, the scraper 42 is installed on the adjustable base 41, the adjustable mechanism 43 is used to drive the adjustable base 41 to slide so that the scraper 42 approaches or moves away from the coating mechanism 3, the adjustable screw is screwed to the adjustable base 41, and the machine body 1 is provided with an abutment structure 11, the adjustable screw being used to abut against the abutment structure 11.

[0024] This invention only requires adjusting the distance by controlling the adjusting seat 41 to move closer to the contact structure 11 via the adjusting mechanism 43. When the adjusting screw contacts the contact structure 11, the adjusting seat 41 can no longer move towards the contact structure 11. At this point, the distance between the doctor blade 42 and the coating roller 32 of the coating mechanism 3 is the thickness of the coating. If adjustment is needed, the adjusting screw is rotated to control its movement relative to the adjusting seat 41, thus changing the position of the adjusting seat 41 when it contacts the contact structure 11, thereby adjusting the distance between the doctor blade 42 and the coating mechanism 3. Because the distance the adjusting screw moves back and forth in one revolution is very small, high-precision adjustment is achieved.

[0025] In this embodiment, the adjusting seat 41 is provided with a limiting seat 44, and the adjusting screw is screwed to the adjusting seat 41. The two ends of the adjusting screw are respectively provided with a handle 47 and a contact member 48, the contact member 48 being used to abut against the contact structure 11. That is, the handle 47 makes the control of the adjusting screw easier, and the contact member 48 makes the collision between the adjusting screw and the contact structure 11 indirect. The contact member 48 can be made of common materials such as rubber, thereby buffering and offsetting the force generated by the collision, which helps to prevent deformation of the adjusting screw and ensures the adjusting accuracy.

[0026] In this embodiment, the pitch adjustment mechanism 43 includes two pitch adjustment components 430. Each pitch adjustment component 430 includes a pitch adjustment cylinder 431, a pitch adjustment slide rail 432, a pitch adjustment slider 433, and a pitch adjustment block 434. The pitch adjustment cylinder 431 is mounted on the pitch adjustment seat 41, the pitch adjustment slider 433 is mounted on the bottom of the pitch adjustment seat 41, and the pitch adjustment slider 433 is slidably connected to the pitch adjustment slide rail 432. The pitch adjustment block 434 is mounted on the piston rod of the pitch adjustment cylinder 431 and is mounted on the machine body 1. This invention controls the pitch adjustment seat 41 to move back and forth along the pitch adjustment slide rail 432 by the action of the pitch adjustment cylinder 431, thereby achieving the pitch adjustment effect.

[0027] In this embodiment, a plurality of quick-release structures 420 are provided between the scraper 42 and the adjusting seat 41. Each quick-release structure 420 includes a mounting base 421, a quick-release component 422, and a top cover 423. The mounting base 421 is provided with a mounting groove 425 with a top opening. The quick-release component 422 has a mounting shaft 424, which is mounted in the mounting groove 425. The top cover 423 is detachably disposed on the top of the mounting base 421. The end of the scraper 42 is connected to the quick-release component 422.

[0028] In actual use, the mounting base 421 and the top cover 423 are fixed together by screws 427. The top cover 423 covers the mounting base 421 to seal the mounting groove 425, thus confining the mounting shaft 424 within the mounting groove 425 and achieving a fixed installation. When it is necessary to disassemble the scraper 42, simply loosen the screws 427 to separate the top cover 423 from the mounting base 421, allowing the mounting shaft 424 to be removed from the mounting groove 425. This separates the quick-release piece 422 from the mounting base 421, thereby enabling the scraper 42 connected to the quick-release piece 422 to be removed, improving disassembly and assembly efficiency.

[0029] The number of quick-release structures 420 corresponds to the length of the scraper 42. In this embodiment, there are four quick-release structures 420, and adjacent quick-release structures 420 are spaced apart to ensure the stable installation of the scraper 42.

[0030] Specifically, the quick-release structure 420 also includes a rotating cylinder 426, which drives the quick-release component 422 to rotate. The rotating cylinder 426 is used to drive the quick-release component 422 to rotate, and the mounting shaft 424 is rotatably mounted in the mounting groove 425.

[0031] Specifically, the cylinder body of the rotating cylinder 426 is rotatably connected to the end of the quick-release piece 422, and the piston rod of the rotating cylinder 426 is rotatably connected to a fixed piece (such as the adjusting seat 41 in this embodiment). By driving the rotating cylinder 426, the quick-release piece 422 can be rotated, which achieves the effect of rotating the scraper 42. This can be used to adjust the distance and relative posture between the scraper 42 and the coating roller 32.

[0032] In this embodiment, the coating mechanism 3 includes a coating motor 31, a coating roller 32, and two holding rollers 33, all of which are disposed on the machine body 1. The coating motor 31 is used to drive the coating roller 32 to rotate, and the coating roller 32 is located between the two holding rollers 33. The two holding rollers 33 are respectively provided with lifting components 34, which are used to drive the holding rollers 33 to rise and fall.

[0033] The coating roller 32 is driven by the coating motor 31 to rotate, thereby picking up the paint from the paint container (not shown in the figure) set in the machine body 1 and coating it onto the film material guided by the two holding rollers 33. The holding rollers 33 guide the film material and maintain the film material with a certain tension to ensure that the film material is in a sufficiently open state and that the paint adheres reliably.

[0034] Specifically, the coating mechanism 3 also includes two lifting cylinders 35, each mounted on the machine body 1. The piston rods of the lifting cylinders 35 are fitted with abutment seats 36. Rotating shafts 37 are located at both ends of the coating roller 32, and the abutment seats 36 are used to contact the rotating shafts 37. The lifting cylinders 35 primarily function as brakes. When the rotational speed of the coating roller 32 needs to be controlled, the lifting cylinders 35 drive the abutment seats 36 to contact the rotating shafts 37, applying friction to the shafts and thus slowing down the coating roller 32. Combined with the speed control of the coating motor 31 itself, this allows for more stable and precise control of the coating roller 32's speed. Furthermore, the top curvature of the abutment seat 36 is preferably adapted to the rotating shaft 37 to ensure a proper braking effect.

[0035] Specifically, the lifting assembly 34 includes two lifting modules 340, which are located at both ends of the holding roller 33. Each lifting module 340 includes a lifting screw 341, a lifting seat 342, and a hand crank 343. The lifting seat 342 is slidably mounted on the machine body 1, and the holding roller 33 is rotatably mounted on the lifting seat 342. The lifting screw 341 is screwed to the machine body 1, and the hand crank 343 is installed at one end of the lifting screw 341. The other end of the lifting screw 341 is installed on the lifting seat 342. The lifting modules 340 allow for high-precision adjustment of the height of the holding roller 33, thereby achieving the effect of adjusting the distance between the coating roller 32 and the film material.

[0036] Specifically, the lifting module 340 also includes a scale 344 and an indicator 345. The indicator 345 is installed on the lifting base 342, and the scale 344 is installed on the machine body 1. The indicator 345 is used to point to the scale of the scale 344, so that the staff can intuitively check the current height of the holding roller 33.
