This material is widely used in interior decoration and furniture manufacturing, and has the advantages of convenience, environmental protection, and beauty. In order to ensure the uniformity of the coating, roller coating is often used. However, during the coating process, since the roller brush is in contact with the board for a long time, impurities are easily adhered to the paint.

[0013] Beneficial Effects

[0014] The present invention provides a wood veneer UV coating device, which has the following beneficial effects compared with the prior art:

[0015] 1. When it is necessary to clean the paint attached to the coating cylinder, the user starts the motor B, so that the screw rod fixedly connected on its output shaft rotates synchronously, and drives the slide frame threadedly connected thereon, so that the slide frame starts to move linearly along the connection between it and the connecting rod, thereby gradually sending the coating cylinder between the multiple arc plates through the slide frame, and in this process, the coating cylinder is pushed to contact the screw sleeve. At this time, keep the motor B in the starting state, so that the coating cylinder starts to push the screw sleeve, and the screw sleeve starts to move linearly along the connection between the connecting ear and the limit rod. At this time, since the screw rod does not have the characteristic of self-locking effect, the screw rod starts to rotate at a uniform speed with the cooperation of the screw sleeve threadedly connected thereto, and drives the shaft cylinder fixedly connected thereto to rotate synchronously. At this time, the wheel plate fixedly connected to the shaft cylinder starts to rotate synchronously and gradually stops supporting the connecting rod. In this process, the spring begins to gradually rebound and reset, and begins to push the sliding plate fixedly connected thereto to start linear motion along the connection between it and the sliding rod, so that the arc plate fixedly connected to the sliding plate starts to move synchronously The paint cylinder is then pushed into the cylinder body formed by the multiple arc plates, and the multiple arc plates are tightly fitted to the paint cylinder under the action of the spring elasticity. At this time, the multiple scrapers fixedly connected on the arc plates are synchronously fitted on the paint cylinder, thereby forming multiple independent cavities, which can be buffered by the gasket rings arranged thereon and increase the scraping effect on the paint. At this time, the user can start the motor B in reverse, so that the slide frame threaded on the screw rod starts to slide in reverse, thereby driving the paint cylinder to start sliding out of the cavity formed by the multiple arc plates, and in this process, the paint attached thereto can be scraped onto the multiple scrapers. At the same time, the independent cavities of the multiple scrapers can store the scraped paint to prevent it from adhering to the paint cylinder. At the same time, the cotton plate arranged at the outlet of the arc plate can wipe the surface of the paint cylinder, further increasing the cleaning effect on the paint cylinder.

[0016] 2. When the coating cylinder is pushed into between the multiple arc plates, the multiple arc plates begin to slide synchronously. At this time, the sealing plates fixedly connected to the arc plates begin to slide synchronously. After the multiple arc plates are docked into a barrel body, the two sealing plates are synchronously docked into a semicircular ring. At this time, the coating cylinder is completely pushed into the barrel body formed by the arc plates. At the same time, the plug-in block fixedly connected to the sealing plate is synchronously inserted into the groove of the plug-in disk, thereby fixing the plug-in block on the plug-in disk so that it can rotate synchronously. Then the user can start the negative pressure pump provided in the catheter to pump the diluent in the catheter out through the multiple nozzles provided on the catheter. At this time, since the through holes are provided on the top arc plate, the diluent is continuously pumped into the arc plate. At this time, since the multiple leakage holes provided on the arc plate are The sealing plate is blocked, so the diluent flowing into the arc plate at this time flows through the coating cylinder and gathers on the arc plate. Subsequently, when the motor drives the coating cylinder fixedly connected to its output shaft to start rotating, the coating cylinder can fully contact the diluent on the arc plate and can drive the plug-in disk fixedly connected thereto to start rotating. At this time, the plug-in disk drives the plug-in block plugged thereon to rotate synchronously. At this time, since the protrusion on the plug-in block is stuck in the groove on the plug-in disk, the plug-in block and the plug-in disk are connected as a whole, so that the sealing plate begins to rotate around multiple arc plates in a cycle, thereby beginning to intermittently block the leak hole, so that the liquid in the arc plate can be intermittently emptied, thereby avoiding the diluent concentration in the arc plate being mixed with too much paint, resulting in the inability to effectively dilute the paint on the coating cylinder.

[0033] In the embodiment of the present invention, when it is necessary to clean the paint attached to the coating cylinder 205, the user starts the motor B3004, so that the screw 301 fixedly connected to its output shaft rotates synchronously, and drives the slide 207 threadedly connected thereto, so that the slide 207 starts to move linearly along the connection between it and the connecting rod 208, thereby gradually sending the coating cylinder 205 into between the multiple arc plates 202 through the slide 207, and in the process, the coating cylinder 205 is pushed to contact with the screw sleeve 302. At this time, keep the motor B3004 in the started state, so that the coating cylinder 205 starts to push the screw sleeve 302, so that the screw sleeve 302 starts to move along the connecting ear 303 and the limit rod 305 are connected to perform linear motion. At this time, since the screw rod 304 does not have the characteristic of self-locking effect, the screw rod 304 starts to rotate at a uniform speed under the cooperation of the screw sleeve 302 threadedly connected thereto, and drives the shaft cylinder 306 fixedly connected thereto to rotate synchronously. At this time, the wheel plate 307 fixedly connected to the shaft cylinder 306 starts to rotate synchronously and gradually stops supporting the connecting rod 208. In this process, the spring 3002 starts to gradually rebound and reset, and starts to push the sliding plate 309 fixedly connected thereto to start linear motion along the connection between it and the sliding rod 3001, so that the sliding plate 309 fixedly connected to the sliding plate 309 The arc plates 202 begin to slide synchronously, so that the multiple arc plates 202 begin to fit toward the coating cylinder 205. When the wheel disc 307 is completely separated from the cam 308, the multiple arc plates 202 are docked and fit on the coating cylinder 205, and the coating cylinder 205 is synchronously pushed into the cylinder body composed of the multiple arc plates 202, and the multiple arc plates 202 are tightly fitted to the coating cylinder 205 under the elastic action of the spring 3002. At this time, the multiple scrapers 203 fixedly connected to the arc plates 202 are synchronously fitted on the coating cylinder 205, thereby forming multiple independent cavities, which can be buffered by the gasket rings arranged thereon, and increase In order to increase the scraping effect on the paint, the user can start the motor B3004 in reverse at this time, so that the slide 207 threadedly connected to the screw rod 301 starts to slide in the opposite direction, thereby driving the coating cylinder 205 to start sliding out of the cavity formed by the multiple arc plates 202. In this process, the paint attached to it can be scraped onto the multiple scrapers 203. At the same time, the independent cavities of the multiple scrapers 203 can store the scraped paint to prevent it from adhering to the coating cylinder 205. At the same time, the cotton board 204 arranged at the outlet of the arc plate 202 can wipe the surface of the coating cylinder 205, further increasing the cleaning effect of the coating cylinder 205.

[0034] Specifically, the dilution component 4 includes a sealing plate 401, a leakage hole 402, an insert block 403 and an insert disk 404. The two sealing plates 401 are symmetrically rotatably connected to the arc plate 202. The leakage hole 402 is symmetrically arranged on the two arc plates 202 on the bottom side.

A roller 407 is symmetrically rotatably connected to the frame 101. The two rollers 407 cooperate with each other and are transmission-connected to a conveyor belt 408. Any of the rollers 407 is fixedly connected to the output shaft of the motor, and a through hole is provided at the top of the arc plate 202 facing the nozzle 406.

[0036] In the embodiment of the present invention, when the coating cylinder 205 is pushed into between the multiple arc plates 202, the multiple arc plates 202 begin to slide synchronously. At this time, the sealing plate 401 fixedly connected to the arc plate 202 begins to slide synchronously. After the multiple arc plates 202 are docked into a barrel body, the two sealing plates 401 are synchronously docked into a semicircular ring. At this time, the coating cylinder 205 is completely pushed into the barrel body formed by the arc plates 202. At the same time, the plug block 403 fixedly connected to the sealing plate 401 is synchronously inserted into the groove of the plug disk 404, thereby fixing the plug block 403 on the plug disk 404 so that it can rotate synchronously. Subsequently, the user can start the negative pressure pump provided in the catheter 405, so that the diluent in the catheter 405 is pumped out through the multiple nozzles 406 provided on the catheter 405. At this time, since the top arc plate 202 is provided with a through hole, the diluent is continuously pumped into the arc plate 202. At this time, due to the multiple leakage holes provided on the arc plate 202 The hole 402 is blocked by the sealing plate 401, so the diluent flowing into the arc plate 202 at this time flows through the coating cylinder 205 and then gathers on the arc plate 202. Subsequently, when the motor 206 drives the coating cylinder 205 fixedly connected to its output shaft to start rotating, the coating cylinder 205 can fully contact the diluent on the arc plate 202, and can drive the plug-in disk 404 fixedly connected thereto to start rotating. At this time, the plug-in disk 404 drives the plug-in block 403 plugged thereon to rotate synchronously. At this time, since the protrusion on the plug-in block 403 is stuck in the groove on the plug-in disk 404, the plug-in block 403 is connected to the plug-in disk 404 as a whole, so that the sealing plate 401 begins to circulate around the multiple arc plates 202, thereby beginning to intermittently block the leakage hole 402, so that the liquid in the arc plate 202 can be intermittently emptied, thereby avoiding the diluent concentration in the arc plate 202 being mixed with too much paint, resulting in the inability to effectively dilute the paint on the coating cylinder 205.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0038] The fixed connection referred to in this application refers to a connection in which a part or component is fixed without any relative movement, which can be divided into detachable connection and non-detachable connection.

[0039] (1) Removable connection: The parts are fixed together by screws, splines, wedge pins, etc. This connection method can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0040] (2) Non-detachable connection: mainly refers to welding, riveting and tenoning. Since forging, sawing or oxygen cutting are required for disassembly during maintenance or replacement, spare parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.) during connection.

[0041] The sliding connection referred to in the present application means that the component can slide along a linear trajectory, and the hinged connection referred to in the present application means that the component can rotate along an axial constraint.

[0042] In some cases, the sliding connection and hinge referred to in the present application may also be damped so that the components have the ability to maintain a desired position.
