Description

Technical Field

[0001] The invention relates to the field of furniture board processing, and in particular to an automatic painting device for bamboo-wood furniture boards with a heating function and a process thereof. Background Art

[0002] The automatic painting device for bamboo and wood furniture boards with heating function has the following main functions: it can automatically spray paint on bamboo and wood furniture boards according to preset procedures and parameters, which greatly improves the spraying efficiency compared to manual painting, and can realize continuous and rapid painting operations on a large number of bamboo and wood furniture boards, which is suitable for large-scale production.

[0003] In the field of bamboo and wood furniture production, the painting process of bamboo and wood furniture boards plays a key role in product quality. Due to their natural characteristics, bamboo and wood materials often contain a certain amount of moisture. If the moisture is not treated before painting, as the moisture evaporates after painting, it is very easy to cause bubbles, cracks, and peeling on the paint surface, seriously affecting the appearance and durability of the furniture board. In traditional processes, natural drying or simple drying equipment is often used to remove moisture from bamboo and wood, but natural drying is restricted by factors such as weather and site, and the efficiency is extremely low; simple drying equipment is difficult to accurately control the temperature, which can easily cause bamboo and wood boards to be over-dried or unevenly dried, affecting the quality of the boards.

[0004] To overcome the above problems, modern bamboo and wood furniture board automatic painting devices have introduced a heating and dehydration process. Considering that bamboo and wood materials are very likely to get damp again after dehydration, the heating process is set inside the automatic painting device to closely connect the dehydration and painting processes. Once the bamboo and wood furniture board is heated and dehydrated, it can immediately enter the painting process, effectively preventing the board from reabsorbing moisture during transportation, ensuring the dry state of the board before painting, and laying the foundation for good paint adhesion.

[0005] After painting, the paint layer on the surface of the board is in a fluid or semi-fluid state. If the board moves at this time, the paint fluid is easily displaced by external forces, resulting in uneven paint thickness, dripping, missing spray and other defects. To avoid such problems, the automatic painting device also integrates the heating and drying process inside. In this way, the board does not need to be transferred after painting, and can be dried directly in the device, reducing the risk of paint displacement caused by handling and other operations, and ensuring the uniformity and integrity of the paint surface.

[0006] Although the traditional hot air blower heating method can quickly increase the ambient temperature, it has obvious disadvantages in the drying process of bamboo and wood furniture boards after painting. The strong airflow blown by the hot air blower can easily impact the paint surface that has just been sprayed, destroying the flatness of the paint surface, causing ripples and uneven defects on the paint surface. Therefore, current automatic painting devices mostly use heating plates for radiant heat heating. The heating plate transfers heat evenly to the surface and paint layer of the bamboo and wood furniture board through thermal radiation, avoiding the interference of strong airflow on the paint surface and effectively ensuring the quality of the paint surface. However, the heating efficiency of the heating plate is relatively slow, especially when processing a large number of bamboo and wood furniture boards, the longer heating time will significantly reduce the overall production efficiency.

[0007] To solve the above problems, an automatic painting device for bamboo furniture board with heating function and a process thereof are proposed. Summary of the invention

The lower end of the second push rod 8107 is fixedly connected to the first elastic telescopic rod 8116 that is horizontally slidably connected to the base 1, and the outer side of the second push rod 8107 is fixedly connected to the gear 8117.

[0037] The rotating assembly 82 includes a motor 8201 fixedly connected to the upper middle part of the shell 2, the output end of the motor 8201 is fixedly connected to a rotating disk 8202, a third guide groove 8203 is arranged inside the rotating disk 8202, a third support plate 8204 is fixedly connected to the upper inner wall of the shell 2, a second hole 8205 is arranged on the inner side of the third support plate 8204, a third push rod 8206 rotatably connected to the push plate 8103 is arranged on the inner side of the second hole 8205, a second guide rod 8207 fixedly connected to the third push rod 8206 is arranged on the inner side of the third guide groove 8203, the appearance structure of the third guide groove 8203 is an arc shape, and the cooperation mode of the third guide groove 8203 and the second guide rod 8207 is a clearance cooperation, so that the rotation of the third guide groove 8203 can drive the second guide rod 8207 to move outward.

[0038] The scraping mechanism 9 includes a scraper 901 arranged on one side of the push plate 8103, a third groove 902 is arranged on one side of the second groove 8108, a connecting rod 903 fixedly connected to the scraper 901 is arranged on the inner side of the third groove 902, a vacuum cleaner 904 is connected to the upper side of the same side of the outer shell 2 and the cylinder 3, a slide groove 905 is arranged inside the push plate 8103, a slider 906 fixedly connected to the scraper 901 is arranged on the inner side of the slide groove 905, and a spring 907 is fixedly connected to one end of the slider 906.

[0039] Place the bamboo furniture board inside the outer shell 2, start the motor 8201 to drive the rotating disk 8202 to rotate, so that the pushing plate 8103 and the heating plate 8104 move toward the middle to heat the surface of the bamboo furniture board, and drive the scraper 901 to move toward the middle. When the scraper 901 moves back, the surface of the pushing plate 8103 is cleaned. After the painting is completed, the pushing plate 8103 does not move to heat and dry the surface of the bamboo furniture board.

[0040] When spraying, the motor 8201 is started by the external controller to drive the rotating disk 8202 to rotate, and the vacuum cleaner 904 is started at the same time, so that the third guide groove 8203 rotates. Because the appearance structure of the third guide groove 8203 is an arc shape, and the third guide groove 8203 and the second guide rod 8207 are matched in a clearance fit, and the third push rod 8206 is nested on the inner side of the second hole 8205, the third push rod 8206 moves inward, driving the push plate 8103 rotatably connected to the third push rod 8206 to move toward the middle, driving the scraper 901 slidably connected to the push plate 8103 to move toward the middle, and the push plate 8103 moves toward the middle, driving the first groove 8105 and the first push rod 8206 to move. The rod 8106, the second push rod 8107 and the first guide rod 8110 move toward the middle. At this time, the first guide rod 8110 is on the inner side below the first guide groove 8109. When it moves to the innermost point of the third guide groove 8203, the first guide rod 8110 also moves to the point c of the first guide groove 8109. Because the height of the first guide groove 8109a point is lower than the height of the first guide groove 8109b point, and the height of the first guide groove 8109c point is higher than the height of the first guide groove 8109d point, the controller controls the motor 8201 to rotate in the opposite direction, driving the push plate 8103, the first groove 8105, the first push rod 8106, the second push rod 8107 and the first guide rod 8110 to move outward. At this time, the first guide rod 8110 is pushed by the first elastic telescopic rod 8116 to be located above the first guide groove 8109d point, so that the first guide rod 8110 moves upward along the oblique side of the first guide groove 8109 to the upper inner part of the first guide groove 8109, and the first guide rod 8110 continues to move outward. When the first guide rod 8110 moves to the inner side of the second guide groove 8115, the first push rod 8106, the second push rod 8107 and the gear 8117 move upward. At this time, the first push rod 8106 has been pushed out from the first hole 8102, and the gear 8117 contacts and rotates with the first rack 8111. Because the connection mode of the push plate 8103 and the scraper 901 is a sliding connection, at this time the connecting rod 903 The third groove 902 has been in contact with the inner side of the third groove 902 near the center of the base 1. During the rotation, the connecting rod 903 is pushed and moves on the surface of the pushing plate 8103 to scrape off the paint adhered to the outer side of the pushing plate 8103 by the last spraying. At this time, the vacuum cleaner 904 is turned on to vacuum, and the pushing plate 8103 and the heating plate 8104 are driven to rotate so that the pushing plate 8103 goes back sideways. When the first guide rod 8110 moves to the position of the second second guide groove 8115, the first guide rod 8110 rises again so that the gear 8117 and the second rack 8113 mesh and rotate again. Because the teeth of the second rack 8113 are opposite to the teeth of the first rack 8111, the pushing plate 8103 rotates in the opposite direction.The spring 907 and the connecting rod 903 are reset to prepare for the next cleaning. In summary, the paint adhered to the outer side of the push plate 8103 by the last spraying can be scraped off, thereby improving the heating efficiency.

[0041] After the cleaning is completed, the bamboo and wooden furniture is placed inside the outer shell 2. At this time, the vacuum cleaner 904 stops working, and the motor 8201 is started again to continue rotating, so that the pushing plate 8103 and the heating plate 8104 continue to move toward the middle, so that the heating plate 8104 has a wider range of movement and improved heating efficiency.

[0042] When the bamboo furniture board is being dried, the fibers of the bamboo furniture board will bulge, which increases the adhesion area and makes the painting effect better. Since the sliding component 81 is provided with four groups, the four pushing plates 8103 move toward the middle at the same time, so that the airflow can push the fibers upward in multiple directions, causing the fibers to bulge, increasing the adhesion area and making the painting effect better.

[0043] Because the four pushing plates 8103 move toward the middle at the same time and approach the center position of the base 1, the airflow converges in the middle and can only move upward and downward, so that the fibers just pushed up are affected by the vertical downward airflow, causing the more raised fibers to bend. The originally relatively flat bamboo and wood surface becomes rougher and more layered, greatly increasing the surface area. The larger surface area provides more attachment points for the paint, and the paint can better penetrate into the fiber gaps, thereby effectively increasing the adhesion between the paint and the bamboo and wood materials, which helps to improve the quality of painting.

[0044] After the pushing plate 8103 completes the pushing, it will rotate and move outward in a sideways manner, thereby reducing the flow of the driven air flow and reducing the impact on the surface fibers of the bamboo furniture board.

[0045] After the heating before painting is completed, the heating plate 8104 is stopped and the nozzle 5 is started for spraying. After the spraying is completed, the heating plate 8104 is turned on again to heat so that the paint on the surface of the bamboo furniture board dries. At this time, the push plate 8103 and the heating plate 8104 are facing the bamboo furniture board with a larger area.

[0046] Because the push plate 8103 is cleaned by the scraper 901 before heating the bamboo furniture board before painting each time, and then the bamboo furniture board is heated before painting, the paint impurities on the push plate 8103 are reduced from falling onto the bamboo furniture board that needs to be painted, thereby improving the painting quality.
