Description

Technical Field

[0001] The invention relates to the technical field of billboard manufacturing, in particular to a surface rapid coloring device for billboard manufacturing. Background Art

[0002] The rapid coloring device for billboard production can make the pigment evenly cover the billboard surface through a specific design and working principle, avoiding color difference and unevenness, and thus completing the billboard surface coloring work in a shorter time, greatly shortening the production cycle. Although the rapid coloring device can usually achieve efficient coloring, there may be certain deviations in color accuracy. Due to the accuracy limitations of the equipment or the characteristics of the pigment, it may not be possible to fully restore the color in the design, resulting in the final billboard color not being consistent with expectations.

[0003] In the patent document with the publication number CN116809266B, a rapid surface coloring device for billboard production is disclosed. In view of the problem that the existing billboard coloring method consumes a lot of manpower and materials, the following scheme is proposed, including a fixed bottom box, the top of which is provided with a through cavity, and one end of the through cavity is set as a melting cavity, and the other end of the through cavity is set as a discharge cavity, and the top two sides of the fixed bottom box are fixed with supporting side frames by bolts. In the waxing process of the present invention, the bottom wax injection outer block can contact the billboard and produce extrusion wax injection. When the contact extrusion occurs, the internal sealing inner block is lifted up, so that the internal molten wax liquid flows out and spreads on the billboard surface, and continues to move through the rear rotating wax cutting roller and the circumferential cutter head to scrape the wax layer on the billboard surface into a thin layer, which can be preferably set to 1mm wax layer coating.

[0004] When the above device is in use, the wax-injected outer block can contact the billboard, thereby triggering the sealing inner block to be lifted up, allowing the melted wax liquid inside to flow out. Since the wax liquid is in a molten state, it is in a semi-liquid and semi-solid state, and it is easy to produce marks during the contact with the wax-injected outer block. In addition, the wax-injected block is sticky with the wax liquid when it contacts the billboard. After the wax liquid solidifies, it contacts the wax liquid on the billboard and it is also easy to produce marks of various shapes. If the mark is deep, the subsequent wax-cutting roller and the circular cutter head cannot completely clearly determine the position of the mark according to the requirements of the wax thickness of the billboard, thereby interfering with the aesthetics of the waxing of the billboard. Summary of the invention

[0005] The purpose of the present invention is to address the problem in the background technology that a wax-injected outer block can contact a billboard, and when the wax-injected block contacts the billboard, it is adhered to wax liquid, and after the wax liquid solidifies, it contacts the wax liquid on the billboard and is also likely to produce marks of various shapes. If the mark is deep, the subsequent wax-cutting roller and the circular cutter head cannot completely clearly determine the position of the mark according to the requirements of the wax thickness of the billboard, which interferes with the aesthetics of the waxing of the billboard.

The built-in threaded transmission tube is close to the pipeline position of the flow transfer tube and the external threaded clamping ring produces a scraping action to cooperate with the rotation of the threaded rotating rod, avoiding the melted wax liquid residue blocking the output port and affecting the later use; 2. Since the clamping plate is located inside the auxiliary protection frame and is made of rubber material on one side, and there is a pressure sensing component between the rubber material and the clamping plate, the limiting force of the clamping plate on both sides of the billboard is equal. When the auxiliary protection frame is transmitting the billboard, the impact of its vibration on the billboard is reduced, the processing quality of the billboard is improved, and the position displacement of the billboard is avoided during processing; 3. The blocking plate is adsorbed by the magnetic block through power, so that the blocking plate does not block the area directly below the laser head. The laser head at this position releases laser light through the laser cover to melt the wax layer of the billboard at the corresponding vertical position. In the position where coloring is not required, the magnetic block is not powered on, and the blocking plate moves along the horizontal slideway to the area directly below the laser head through the elastic force of the spring, blocking the laser of the laser head and retaining the wax layer on the billboard at the vertical position, so that the billboard can be quickly colored according to the processing requirements. 4. As the curved conveyor belt transmits back and forth, hot water is stored in the water tank between the supporting water tank and the water baffle. The billboard moves back and forth on the curved conveyor belt, generating convection with the flow of hot water, so that the excess wax layer on the surface is directly melted away, and the adhesion of the paint surface will remain on the billboard, thus obtaining a colored billboard, thereby utilizing the back and forth impact of water on the billboard to improve the wax removal effect of the billboard.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1 - Figure 4 As shown, a surface rapid coloring device for billboard production proposed by the present invention comprises an billboard transmission component 1, the billboard transmission component 1 comprises a supporting water tank 101, an auxiliary protection frame 103 is fixedly installed on one side of the supporting water tank 101, a plurality of transmission rollers 104 are installed between the auxiliary protection frame 103 and the supporting water tank 101, an billboard limiting component 2 is installed on one side of the billboard transmission component 1, a wax liquid injection component 3, a wax melting mechanism 4 and a wax removal component 6 are installed on the inner side of the billboard transmission component 1, and a wax washing component 5 is installed inside the billboard transmission component 1. The overall working process is waxing, wax melting, painting and wax removal. Waxing is first performed under the operation of the wax liquid injection component 3 through the transmission of the auxiliary protection frame 103, and then the thickened or irregular wax layer is beautified through the wax removal component 6, and then the wax is melted under the operation of the wax melting mechanism 4, and then the painting component is used for painting, and finally the wax is washed through the wax washing component 5.

[0021] like Figure 1 - Figure 2As shown, the advertising board limiting assembly 2 includes two limiting rotating blocks 203 fixedly installed on the top of the auxiliary protection frame 103, the two limiting rotating blocks 203 are rotatably installed with a bidirectional threaded rod 204 inside, the middle of the bidirectional threaded rod 204 is fixedly installed with a first gear 205, the outer side of the first gear 205 is meshedly connected with a second gear 206, the second gear 206 is installed on the top of the auxiliary protection frame 103 through a first motor, the two sides of the bidirectional threaded rod 204 are threadedly connected with two built-in threaded rods 202, the bottom of the two built-in threaded rods 202 are installed with the same number of clamping plates 201, the two clamping plates 201 are slidably installed on both sides of the auxiliary protection frame 103, the first motor drives the second gear 206 to rotate, and the second gear 206 is connected to the first gear 205 by screwing. The meshing drives the first gear 205 to rotate, and the first gear 205 drives the bidirectional threaded rod 204 to rotate. Since the threads on both sides of the bidirectional threaded rod 204 are in opposite directions, the bidirectional threaded rod 204 drives the built-in threaded rod 202 to move toward one side of the auxiliary protection frame 103. At this time, the built-in threaded rod 202 drives the clamping plate 201 to perform a limiting movement toward the billboard. Since the clamping plate 201 is located on one side of the inner part of the auxiliary protection frame 103 and is made of rubber material, and there is a pressure sensing component between the rubber material and the clamping plate 201, the limiting force of the clamping plate 201 on both sides of the billboard is equal. When the auxiliary protection frame 103 is transmitting the billboard, the impact of its vibration on the billboard is reduced, thereby improving the processing quality of the billboard and avoiding position displacement of the billboard during processing.

[0022] like Figure 7 - Fig.12As shown, the wax liquid injection assembly 3 includes a plurality of first electric telescopic columns 301 fixedly installed at the bottom of the auxiliary protection frame 103, a clamping rod 302 is fixedly installed between the plurality of first electric telescopic columns 301, and the same number of hollow placement rods 303 are fixedly installed at the bottom of the plurality of first electric telescopic columns 301, the inside of the hollow placement rod 303 is rotatably connected with a threaded rotating rod 305, the outer side of the threaded rotating rod 305 is threadedly connected with an internal threaded clamping ring sleeve 306, the outer side of the internal threaded clamping ring sleeve 306 is fixedly connected with an external protective ring sleeve 315, the external protective ring sleeve 315 is slidably installed in the interior of the hollow placement rod 303 through a vertical groove provided on the inner side of the hollow placement rod 303, and the outer side of the internal threaded clamping ring sleeve 306 is rotatably installed with an annular two-way clamping block 31 2. An external threaded snap ring 313 is fixedly installed on one side of the annular two-way clamping block 312 away from the internal threaded snap ring sleeve 306. An arc-shaped clamping groove is provided on one side of the internal threaded snap ring sleeve 306, and the annular two-way clamping block 312 fits in the clamping groove. Then, the external threaded snap ring 313 rotates in the clamping groove of the internal threaded snap ring sleeve 306 through the annular two-way clamping block 312. Four hollow slideways 309 are provided on the outer side of the threaded rotating rod 305. The same number of clamping blocks 308 are slidably installed on the outer side of the threaded rotating rod 305 through the four hollow slideways 309. The clamping blocks 308 are fixedly installed on the inner wall of the external threaded snap ring 313. The outer side of the external threaded snap ring 313 is threadedly connected with the internal threaded transmission tube 307. One side of the internal threaded transmission tube 307 is connected by a fixed block 3 14 is slidably installed on the inner wall of the external protective ring sleeve 315 to reduce the influence of the external temperature on the inside of the pipeline. When the billboard is located directly below the wax liquid injection assembly 3, the first electric telescopic column 301 first extends toward the side of the billboard to a specified position, and at the same time, the second motor slidably connected inside the first electric telescopic column 301 drives the threaded rotating rod 305 to rotate. Since the external protective ring sleeve 315 slides outward on the hollow placement rod 303 through the limitation of the vertical groove, and the external threaded clamping ring 313 is limited in the hollow slideway 309 by the clamping block 308, the external threaded clamping ring 313 can rotate synchronously with the threaded rotating rod 305, and the external threaded clamping ring 313 is moved along the outer wall of the internal threaded clamping ring sleeve 306 through the annular two-way clamping block 312. Rotate, as the external protective ring sleeve 315 slides, the external threaded retaining ring 313 is supported by the internal threaded retaining ring sleeve 306 and slides outward along the hollow slideway 309 through the clamping block 308, causing the external threaded retaining ring 313 to drive the internal threaded transmission tube 307 to slide outward. In this process, the internal threaded transmission tube 307 is caused to slide outward along the external protective ring sleeve 315 through the fixing block 314 through the external thread transmission of the external threaded retaining ring 313, and the internal threaded transmission tube 307 moves more accurately to the top of the billboard. As the melted wax liquid is transmitted from the internal threaded transmission tube 307 to the billboard, and the melted wax liquid gradually becomes thicker, the internal threaded transmission tube 307 moves upward within the specified range.At the same time, the rotation of the threaded rotating rod 305 in the built-in threaded transmission tube 307 can make the melted wax liquid in the built-in threaded transmission tube 307 active, avoiding solidification and blockage in cold weather. When the processing is completed, the built-in threaded transmission tube 307 and the external protective ring sleeve 315 are stored in the hollow placement rod 303, and the built-in threaded transmission tube 307 is close to the pipeline position of the flow transfer tube 310 and the external threaded clamping ring 313 produces a scraping action to cooperate with the rotation of the threaded rotating rod 305, so as to avoid the melted wax liquid residue blocking the output port and affecting the later use.

[0023] A slideway is provided on one side of the hollow placement rod 303 and the external protective ring sleeve 315, and a flow transfer tube 310 is fixedly installed inside the internal threaded transmission tube 307. When the internal threaded transmission tube 307 slides outward along the external protective ring sleeve 315, the internal threaded transmission tube 307 drives the flow transfer tube 310 to extend outward through the slideway of the hollow placement rod 303 and the external protective ring sleeve 315 to avoid external influence on the movement of the hollow placement rod 303 and the external protective ring sleeve 315. A retaining ring block 310 is fixedly installed on one side of the internal threaded transmission tube 307. 04. A heat-insulating layer 311 is fixedly installed on one side of the built-in threaded transmission tube 307 facing the external protective ring sleeve 315. When the built-in threaded transmission tube 307 and the external protective ring sleeve 315 are in the storage state, the heat-insulating layer 311 is located between the built-in threaded transmission tube 307 and the external protective ring sleeve 315, thereby reducing the influence of the external temperature on the wax liquid. For example, when the external air is low, the freezing of the inside of the built-in threaded transmission tube 307 is reduced, and more energy is consumed to thaw the wax liquid. The retaining ring block 304 prevents the wax liquid transmitted from the built-in threaded transmission tube 307 from splashing on the outside.

[0024] like Figure 7 - Figure 8As shown, the wax melting mechanism 4 includes a laser head 402 and a magnetic block 405 fixedly mounted at the bottom of the auxiliary protection frame 103. The interior of the auxiliary protection frame 103 is slidably connected with a blocking plate 403 through an opened transverse slideway. A laser cover 401 is fixedly mounted at the bottom of the laser head 402. The magnetic block 405 and the blocking plate 403 are arranged in an electromagnetically attracted state. A spring 404 is fixedly mounted between the blocking plate 403 and the transverse slideway. The wax melting process is carried out directly below the wax melting mechanism 4. The data is first uploaded to the PLC. The PLC controls the wax melting mechanism to process the internal data into color information on each pixel according to the processing requirements. The coloring in the processing requirements The blocking plate 403 is attracted to the position by the magnetic block 405 through electricity, so that the blocking plate 403 does not block the area directly below the laser head 402. The laser head 402 at this position releases laser light through the laser cover 401 to melt the wax layer of the billboard at the corresponding vertical position. In the position where coloring is not required, the magnetic block 405 is not energized, and the blocking plate 403 moves along the horizontal slide to the area directly below the laser head 402 through the elastic force of the spring 404, blocking the laser of the laser head 402 and retaining the wax layer on the billboard at the vertical position. Through the above operation, the wax layer at the coloring position of the billboard is melted, generating colored and non-colored wax layer layers.

[0025] In this embodiment, Figure 1 - Figure 5As shown, the wax washing component 5 includes a curved conveyor belt 501 arranged inside the supporting water tank 101, and water baffles 102 are fixedly connected to both sides of the supporting water tank 101. Two corresponding clamping and positioning blocks 506 are fixedly installed on both sides of the supporting water tank 101, and a conduction component 502 is hinged between the two corresponding clamping and positioning blocks 506. A motor 503 is fixedly installed on one side of the corresponding clamping and positioning blocks 506. The conduction component 502 is fixedly installed on the output shaft of the motor 503, and an auxiliary hinged rod 504 is hinged on the side of the conduction component 502 away from the corresponding clamping and positioning blocks 506. A sliding cavity 505 is opened on the inner wall of the supporting water tank 101, and the auxiliary hinged rod 504 is slidably installed in the sliding cavity 505 on the side away from the conduction component 502. After painting is completed, the billboard moves to the conduction component 502 along the transmission of the auxiliary protection frame 103 to carry out the wax removal process, which is explained here. The motors in this article are all forward and reverse motors, and the motor 503 drives the conductive component 502 to deflect along the corresponding clamping positioning block 506, and the auxiliary hinge rod 504 slides along the sliding cavity 505 and deflects to a suitable position along the connection of the conductive component 502, so that the painted billboard moves to the surface of the curved conveyor belt 501. As the curved conveyor belt 501 transmits back and forth, the supporting water tank 101 and the water baffle 102 store hot water through the water tank. The billboard moves back and forth on the curved conveyor belt 501, and convection is generated with the flow of hot water, so that the excess wax layer on the surface is directly melted and taken away, and the adhesion of the paint surface will remain on the billboard, so that a colored billboard is obtained, thereby using the back and forth impact of water on the billboard to improve the wax removal effect of the billboard. At the same time, as the curved conveyor belt 501 transmits, the billboard is transmitted to the collection position along the arc direction of the curved conveyor belt 501.

[0026] The wax removal component 6 includes a second electric telescopic column 601 fixedly mounted at the bottom of the auxiliary protection frame 103, the second electric telescopic column 601 is internally rotatably connected to a wax removal roller 602, and a painting component is fixedly mounted on one side of the auxiliary protection frame 103. The second electric telescopic column 601 drives the wax removal roller 602 to fit on the billboard to process the excess residue and the excessively thick wax coating on its surface, and the painting component paints the billboard after being processed by the wax melting mechanism 4.
