DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-9 In an embodiment of the present invention, a coating machine for conveniently replacing a coating roller comprises a mounting frame 1, on which a lifting coating device 2, a rubber pressure roller lifting mechanism 3 and a scraper device 4 are respectively provided; The mounting frame 1 comprises a bottom mounting frame 11, a side frame 12 is symmetrically arranged on the top of the bottom mounting frame 11, two bottom fixing columns 13 are arranged at the bottom of the side frame 12, a top fixing column 14 is arranged at the upper end, and a guide roller 15 connected to the side frame 12 is arranged at the lower end of the top fixing column 14; The inner bottom of the side frame 12 is also symmetrically provided with a lifting seat 24, which is meshed and connected with the lifting shaft 23. The two ends of the lifting shaft 23 are respectively connected to the side plate 12 and the lifting turbine 22 on one side, and the lifting turbine 22 is connected to the lifting hand wheel 21.

[0024] By adopting the above technical solution, during the coating process, the lifting handwheel 21 is rotated to drive the lifting turbine 22. When the lifting turbine 22 rotates, the lifting shaft 23 rotates accordingly, and the lifting shaft 23 drives the lifting seat 24 to move up and down, thereby realizing the up and down movement of the coating trough 25. For some products that require very precise coating amount, when the coating amount needs to be reduced, the coating trough 25 can be moved downward to reduce the contact area between the coating and the coating roller 27, thereby accurately controlling the amount of coating per unit area; on the contrary, when the coating amount needs to be increased, the coating trough 25 is moved upward to increase the contact area, which can accurately control the coating amount while adapting to different sizes and shapes of coating rollers 27.

[0025] In this embodiment, the top of the lifting seat 24 is connected to the coating material tank 25, and the upper end of the coating material tank 25 is provided with a coating roller 27, and a coating roller core shaft 211 is provided inside the coating roller 27. One end of the coating roller core shaft 211 is provided with a coating roller bearing seat 26, and the coating roller bearing seat 26 is arranged in the side frame 12 on one side. A positioning seat 28 is provided outside the coating roller bearing seat 26, and the positioning seat 28 is threadedly connected with a hand wheel 29. The hand wheel 29 passes through the positioning plate 218 and is threadedly connected. A fixing nut 210 is also provided at the top position of the positioning plate 218, and is fixed to the side frame 12 on one side through the fixing nut 210; The other end of the coating roller core shaft 211 is provided with a coating roller gear 212, which is meshed and linked with a gear seat 213. The outer end of the gear seat 213 is connected with a synchronous wheel 214, which is connected to a motor synchronous wheel 216 through a synchronous belt 215. The motor synchronous wheel 216 is arranged on a motor 217.

[0026] By adopting the above technical scheme, when in use, the coating roller 27 used this time is first installed on the side frame 12 through the coating roller core shaft 211 and the coating roller bearing seat 26, and then the hand wheel 29 and the positioning plate 218 are threadedly rotated to drive the positioning seat 28 to slide toward the coating roller bearing seat 26, thereby fixing the coating roller bearing seat 26. A fixing nut 210 is also fixed between the positioning plate 218 and the side frame 12 to play a dual fixing role; when the coating roller 27 needs to be replaced, the hand wheel 29 is first rotated, and the hand wheel 29 is separated from the positioning seat 28 and the positioning plate 218 by threaded connection, and then the fixing nut 210 is disassembled to make the positioning plate 218 and the side frame 12 detachable. After the positioning plate 218 is disassembled and the positioning seat 28 is taken out, the coating roller 27 can be replaced, thereby reducing the downtime when replacing the coating roller 27, facilitating rapid switching of different products, and improving production efficiency.

[0027] In this embodiment, a slide rail 31 is symmetrically provided on the top of the side frame 12, and the slide rail 31 is slidably connected to the outer slide seat 32. The slide seat 32 is respectively provided with a rubber pressure roller 1 33 and a rubber pressure roller 2 34 on the upper and lower parts, and a cylinder 1 35 is provided on the top, and the cylinder 1 35 is fixedly installed on the side frame 12. A fastener 36 is provided at the bottom of the slide seat 32.

[0028] By adopting the above technical solution, during the coating process, when the coating is squeezed, the slide 32 can be adjusted up and down through the slide rail 31 and the cylinder 35, so that the operator can accurately control the pressure according to different coating materials and coating thickness requirements. When applying a thicker coating layer, the rubber pressure roller 33 is appropriately lowered to increase its pressure on the coating roller 27, which can ensure that the coating is better absorbed by the cloth and make the coating more uniform and smooth. For the coating of some thin coatings, reducing the pressure can avoid excessive squeezing of the coating and prevent uneven thickness or surface defects of the coating.

[0029] In this embodiment, the interior of the side frame 12 is also connected to a scraper shaft 41, and a constant pressure plate 42 is symmetrically provided on the scraper shaft 41, and a cylinder 2 43 is provided on the constant pressure plate 42. The top of the cylinder 2 43 is connected to a scraper seat 44, and a pad 45 is provided at the upper end of the scraper seat 44. A reinforcing plate 47 is provided at the upper end of the pad 45. The reinforcing plate 47 is connected to a clamping plate 49 through a pressure plate 48, and a scraper 410 is provided at the upper end of the clamping plate 49; an adjusting rod 46 is also provided on the pad 45.

[0030] By adopting the above technical solution, the angle between the scraper 410 and the coating roller 27 can be adjusted by the cylinder 43, and the pressure of the scraper on the coating roller can be accurately controlled by adjusting the air pressure of the cylinder. The cylinder 43 can provide stable and accurate pressure regulation. The operator can quickly adjust the air pressure of the cylinder 43 according to the real-time coating situation, such as changes in the viscosity of the coating, changes in the coating speed, etc., thereby dynamically changing the scraper pressure to keep the coating quality at a high level at all times; the distance between the scraper 410 and the coating roller 27 can be adjusted by the adjusting rod 46, which can adapt to different coating requirements and respond to changes in coating properties at any time.

[0031] The working principle of the present invention is as follows: when in use, the coating roller 27 used this time is first installed on the side frame 12 through the coating roller core shaft 211 and the coating roller bearing seat 26, and then the hand wheel 29 and the positioning plate 218 are threadedly rotated to drive the positioning seat 28 to slide toward the coating roller bearing seat 26, thereby fixing the coating roller bearing seat 26. A fixing nut 210 is also fixed between the positioning plate 218 and the side frame 12 to play a dual fixing role; when the coating roller 27 needs to be replaced, the hand wheel 29 is first rotated to be threadedly connected with the positioning seat 28 and the positioning plate 218 to separate the hand wheel 29 from it, and then the fixing nut 210 is disassembled to make the positioning plate 218 and the side frame 12 detachable. After the positioning plate 218 is disassembled and the positioning seat 28 is taken out, the coating roller 27 can be replaced, thereby reducing the downtime when replacing the coating roller 27, facilitating rapid switching of different products, and improving production efficiency; During the coating process, the lifting hand wheel 21 is rotated to drive the lifting turbine 22. When the lifting turbine 22 rotates, the lifting shaft 23 rotates accordingly. The lifting shaft 23 drives the lifting seat 24 to move up and down, thereby realizing the up and down movement of the coating material tank 25. For some products that require very precise coating amount, when the coating amount needs to be reduced, the coating material tank 25 can be moved downward to reduce the contact area between the coating and the coating roller 27, thereby accurately controlling the amount of coating per unit area; on the contrary, when the coating amount needs to be increased, the coating material tank 25 is moved upward to increase the contact area, which plays a role in accurately controlling the coating amount and can also adapt to different sizes and shapes of the coating roller 27; During the coating process, when the coating is squeezed, the slide 32 can be adjusted up and down through the slide rail 31 and the cylinder 35, so that the operator can accurately control the pressure according to different coating materials and coating thickness requirements. When applying a thicker coating layer, the rubber pressure roller 33 is appropriately lowered to increase its pressure on the coating roller 27, so as to ensure that the coating is better absorbed by the cloth and make the coating more uniform and smooth; and for the coating of some thin coatings, reducing the pressure can avoid excessive squeezing of the coating and prevent uneven thickness or surface defects of the coating; The angle between the scraper 410 and the coating roller 27 can be adjusted by the cylinder 43, and the pressure of the scraper on the coating roller can be accurately controlled by adjusting the air pressure of the cylinder. The cylinder 43 can provide stable and accurate pressure regulation. The operator can quickly adjust the air pressure of the cylinder 43 according to the real-time coating situation, such as changes in the viscosity of the coating, changes in the coating speed, etc., thereby dynamically changing the scraper pressure to keep the coating quality at a high level at all times; the distance between the scraper 410 and the coating roller 27 can be adjusted by the adjusting rod 46 to adapt to different coating requirements and respond to changes in coating properties at any time.
