The paint supply structure of the double-roller coater for painting plate materials can disassemble the paint box for comprehensive cleaning through the fixed block and the connecting block provided by the clamping assembly, thereby avoiding the situation where the paint box cannot be disassembled and cannot be thoroughly cleaned. Secondly, the baffle and the moving rod provided by the unloading assembly can control the flow rate of the paint replenished to the roller coating rod, thereby avoiding excessive paint replenishment causing the paint film of the plate to be too thick, or causing the paint film of the plate to be too thin and fail to meet the requirements.

[0021] The coating supply structure of the double-roller coating machine for spraying paint on a plate is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0022] The present application is described in detail below in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4 In the embodiment, a paint supply structure of a double-roller coater for plate painting is provided, comprising: a base 1, a roller coating cover 101 is installed on the top of the base 1, a paint box 102 is arranged on the top of the roller coating cover 101, a clamping assembly, the clamping assembly is arranged between the roller coating cover 101 and the paint box 102, and is used for disassembling the paint box 102, and a feeding assembly is arranged inside the paint box 102, and is used for controlling the feeding amount of the paint inside the paint box 102. Example

[0023] The clamping assembly includes: a fixing block 2 connected to both sides of the coating box 102, a connecting groove 201 provided at the bottom of the fixing block 2, a connecting block 202 connected to the top of the roller coating cover 101 and matched with the connecting groove 201, a threaded hole 203 provided on one side of the fixing block 2, a bolt 204 matched with the threaded hole 203 is provided on one side of the fixing block 2, and a fixing hole 205 corresponding to the position of the threaded hole 203 is provided on one side of the connecting block 202.

[0024] When the paint box 102 is to be disassembled, the bolt 204 is rotated. After the bolt 204 is rotated, it will be engaged with the thread of the threaded hole 203 and gradually leave the threaded hole 203 and the fixing hole 205. When the bolt 204 completely leaves the fixing hole 205, the fixation of the fixing block 2 is released, so that the paint box 102 can be disassembled. When the paint box 102 is to be installed, the connecting groove 201 is aligned with the connecting block 202. After alignment, the paint box 102 is placed so that the connecting block 202 enters the connecting groove 201. After the connecting block 202 enters the connecting groove 201, the bolt 204 is aligned with the threaded hole 203. After alignment, the bolt 204 is pushed in the direction of the threaded hole 203 so that the bolt 204 contacts the thread of the threaded hole 203. At this time, the bolt 204 is rotated to allow the bolt 204 to enter the threaded hole 203. After entering the threaded hole 203, the bolt 204 will pass through the fixing hole 205, thereby fixing the paint box 102. Example

[0025] The unloading assembly includes: two moving rods 3 arranged on the top of the paint box 102, two moving openings 301 opened on the top of the paint box 102, the bottom ends of the two moving rods 3 respectively pass through the moving openings 301 and extend into the interior of the paint box 102, a baffle 302 connected to the bottom end of the moving rods 3, two limit grooves 303 are opened inside the two moving openings 301, and both side surfaces of the moving rods 3 are connected to limit blocks 304.

[0026] When it is necessary to supply paint to the roller coating rod 402, grab the moving rod 3, and then move the moving rod 3 in the direction away from the feeding pipe 103. When moving, the moving rod 3 will move with the baffle 302, and the baffle 302 will expose the pipe opening of the feeding pipe 103 when moving, so that the paint inside the paint box 102 enters into the feeding pipe 103. When it is necessary to stop the paint supply to the roller coating rod 402, grab the moving rod 3, and then move the moving rod 3 in the direction of the feeding pipe 103, so that the baffle 302 blocks the feeding pipe 103, so that the paint inside the paint box 102 cannot enter into the feeding pipe 103, thereby controlling the paint supply to the feeding pipe 103. Example

[0027] Two feeding pipes 103 are arranged inside the coating box 102, and a through hole 104 matching with the feeding pipe 103 is opened on the top of the roller coating cover 101. The bottom ends of the two feeding pipes 103 extend to the inside of the through hole 104, and the top ends of the feeding pipes 103 are connected to the coating box 102. Two DC motors 4 are installed on one side of the roller coating cover 101, and one side of the DC motor 4 is driven and connected with a rotating rod 401. One end of the rotating rod 401 passes through the roller coating cover 101 and extends to the inside of the roller coating cover 101. One end of the rotating rod 401 is connected to the roller coating rod 402. A control switch is arranged on one side of the base 1, and a transport structure is installed on the top of the base 1. The control switch is connected with the DC motor 4 by electric wires, and the DC motor 4 is powered by an external power supply.

[0028] The DC motor 4 is started by controlling the switch. After the DC motor 4 is started, it will drive the rotating rod 401 to rotate. After the rotating rod 401 rotates, it will rotate with the roller coating rod 402 to coat the plate. At the same time, the feed pipe 103 can enter the roller coating cover 101 through the through hole 104, so that the paint in the feed pipe 103 can fall on the surface of the roller coating rod 402, so as to replenish the paint needed by the roller coating rod 402.

[0029] The specific workflow is:

[0030] The DC motor 4 is started by the control switch. After the DC motor 4 is started, it drives the rotating rod 401 to rotate. After the rotating rod 401 rotates, it will rotate with the roller coating rod 402, so as to apply paint to the plate. At the same time, the unloading pipe 103 can enter the roller coating cover 101 through the through hole 104, so that the paint in the unloading pipe 103 can fall on the surface of the roller coating rod 402, so as to supplement the paint required by the roller coating rod 402;

[0031] When supplying paint to the coating roller rod 402, the moving rod 3 is grasped, and the moving rod 3 is moved away from the feeding pipe 103 after grasping. The moving rod 3 will move with the baffle 302 when moving, and the baffle 302 will expose the pipe opening of the feeding pipe 103 when moving, so that the paint inside the coating box 102 enters the feeding pipe 103. When supplying paint to the coating roller rod 402 is to be stopped, the moving rod 3 is grasped, and the moving rod 3 is moved in the direction of the feeding pipe 103 after grasping, so that the baffle 302 blocks the feeding pipe 103, so that the paint inside the coating box 102 cannot enter the feeding pipe 103, thereby controlling the paint supply of the feeding pipe 103;

[0032] When the paint box 102 is to be disassembled, the bolt 204 is rotated. After the bolt 204 is rotated, it will be engaged with the thread of the threaded hole 203 and gradually leave the threaded hole 203 and the fixing hole 205. When the bolt 204 completely leaves the fixing hole 205, the fixation of the fixing block 2 is released, so that the paint box 102 can be disassembled. When the paint box 102 is to be installed, the connecting groove 201 is aligned with the connecting block 202. After alignment, the paint box 102 is placed so that the connecting block 202 enters the connecting groove 201. After the connecting block 202 enters the connecting groove 201, the bolt 204 is aligned with the threaded hole 203. After alignment, the bolt 204 is pushed in the direction of the threaded hole 203 so that the bolt 204 contacts the thread of the threaded hole 203. At this time, the bolt 204 is rotated to allow the bolt 204 to enter the threaded hole 203. After entering the threaded hole 203, the bolt 204 will pass through the fixing hole 205, thereby fixing the paint box 102.
