Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a coating machine for uniformly coating can lids. (Refer to...) Figures 1-5 A coating machine for uniformly coating can lids includes a frame 1. A first motor 2 is fixedly connected to one side of the frame 1. A first rotating rod 3 is fixedly connected to the output end of the first motor 2. A coating roller 4 is fixedly sleeved on the surface of the first rotating rod 3. One end of the first rotating rod 3 extends through to the outside of the frame 1. A frame 5 is fixedly connected to the top of the frame 1. A first cylinder 6 is fixedly connected to the top of the frame 5. The output end of the first cylinder 6 extends through the frame 5 and is fixedly connected to a lifting shell 7. A lifting frame 19 is provided at the bottom of the lifting shell 7. A component is fixedly connected to one side of the lifting frame 19. The second motor 12 has a second rotating rod 13 fixedly connected to its output end. One end of the second rotating rod 13 extends through to the right side of the lifting frame 19. A lifting roller 14 is fixedly sleeved on the surface of the second rotating rod 13. Limiting rods 15 are fixedly connected to the four corners of the top of the lifting frame 19. Springs 16 and limiting sleeves 17 are sequentially sleeved on the surface of the limiting rods 15 from bottom to top. The surface of the limiting sleeves 17 is fixedly connected to the lifting shell 7. A control button 18 is fixedly connected to the top of the lifting frame 19. A braking mechanism 8 and a scraper assembly 9 are respectively provided on the surface of the frame 1.

[0025] The braking mechanism 8 includes a fixed base 801, which is fixedly connected to the right side of the top of the frame 1. Locking discs 802 are provided at the top and bottom of the left side of the fixed base 801. A rotating disc 803 is provided on the left side of the locking disc 802. The left sides of the two rotating discs 803 are fixedly connected to the first rotating rod 3 and the second rotating rod 13, respectively. By setting a control button 18, when an object enters between the coating roller 4 and the lifting roller 14, the lifting roller 14 will be squeezed and move upwards. The lifting roller 14 will then move the control button 18 upwards until the control button is pressed down. When the control button 18 contacts the lifting housing 7, a control signal is sent to the outside to control the first motor 2 and the second motor 12 to shut down and the second cylinder 804 to open. When the first motor 2 and the second motor 12 are shut down, they will no longer drive the coating roller 4 and the lifting roller 14 to rotate. When the second cylinder 804 is opened, it drives the locking disc 802 to lock the rotating disc 803, preventing the coating roller 4 and the lifting roller 14 from continuing to rotate. This also prevents the items from being continuously squeezed by the coating roller 4 and the lifting roller 14, thus improving the safety of the coating machine.

[0026] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 A second cylinder 804 is fixedly connected to the right side of the fixed base 801. The output end of the second cylinder 804 passes through the inner cavity of the fixed base 801 and is fixedly connected to a pressure block 805. A lifting plate 806 is slidably connected to the top left side of the pressure block 805. A pressure rod 807 is fixedly connected to the left side of both the lifting plate 806 and the pressure block 805. One end of the pressure rod 807 passes through the fixed base 801 and is fixedly connected to the locking disc 802. Two limiting telescopic rods 808 are fixedly connected to the top left side of the lifting plate 806. One end of the limiting telescopic rod 808 passes through the fixed base 801 and is fixedly connected to the lifting frame 19. By setting the operation of the second cylinder 804, the locking disc 802 can be driven to move to the left to lock the rotating disc 803, thereby preventing the coating roller 4 and the lifting roller 14 from continuing to rotate. The limiting telescopic rod 808 facilitates the connection between the lifting plate 806 and the lifting frame 19, and also facilitates the lifting frame 19 to drive the lifting plate 806 to move.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5A slider 809 is fixedly connected to both the front and rear sides of one side of the lifting plate 806. A groove 810 for use with the slider 809 is opened on the left side of the pressure block 805. One side of the slider 809 extends into the inner cavity of the groove 810. The slider 809 is T-shaped. A guide roller 10 is rotatably connected between the two sides of the inner cavity of the frame 1 and behind the coating roller 4 via a rotating shaft. A receiving box 11 is provided at the bottom of the inner cavity of the frame 1. The groove 810 facilitates the use of the slider 809. The slider 809 and the groove 810 facilitate the connection between the lifting plate 806 and the pressure block 805. The guide roller 10 guides the material. The receiving box 11 collects the falling material.

[0028] Reference Figure 1 and Figure 2 The scraper assembly 9 includes a fixing frame 901 located behind the coating roller 4. The bottom of the fixing frame 901 is fixedly connected to the frame 1. A handwheel 902 is provided on the top of the fixing frame 901, and a screw 903 is fixedly connected to the bottom of the handwheel 902. One end of the screw 903 passes through the inner cavity of the fixing frame 901 and is rotatably connected to an adjusting plate 904 via a bearing. A scraper 905 is fixedly connected to the bottom of the adjusting plate 904. The surface of the adjusting plate 904 is slidably connected to the inner wall of the fixing frame 901. By setting the fixing frame 901, the installation of the screw 903 can be facilitated, and the movement range of the adjusting plate 904 can be limited. By setting the handwheel 902, the user can easily rotate the screw 903. The rotation of the screw 903 will drive the adjusting plate 904 and the scraper 905 to move downward, so that the height of the scraper 905 can be adjusted as needed to ensure uniform coating.

[0029] Working principle: Raw materials for the can lid can pass between the coating roller 4 and the lifting roller 14, and are finally conveyed by the guide roller 10. When the height of the lifting roller 14 needs to be adjusted, the first cylinder 6 can be controlled to operate. The operation of the first cylinder 6 can drive the lifting shell 7, the lifting frame 19, and the lifting roller 14 to adjust their height so that they can closely adhere to the material. Controlling the operation of the first motor 2 and the second motor 12 can drive the coating roller 4 and the lifting roller 14 to rotate and coat the material. The user can rotate the screw 903 through the handwheel 902. The rotation of the screw 903 will drive the adjusting plate 904 and the scraper 905 to move downward, so that the scraper 905 can be adjusted in height as needed to ensure uniform coating. When the operator's hand or external objects enter between the coating roller 4 and the lifting roller 14, the... The coating roller 4 is fixed. When the lifting roller 14 is squeezed, it moves upward. The lifting roller 14 drives the control button 18 to move upward until the control button 18 contacts the lifting housing 7. When the control button 18 is triggered, a control signal is sent to the outside to control the first motor 2 and the second motor 12 to shut down and the second cylinder 804 to open. When the first motor 2 and the second motor 12 are shut down, they will no longer drive the coating roller 4 and the lifting roller 14 to rotate. The second cylinder 804, through the cooperation of the pressure block 805, the lifting plate 806 and the pressure rod 807, can drive the locking plate 802 to move and lock the rotating plate 803, preventing the coating roller 4 and the lifting roller 14 from continuing to rotate. This also prevents the items from being continuously squeezed by the coating roller 4 and the lifting roller 14, improving the safety of the coating machine.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
