Description

Technical Field

[0001] The invention relates to the technical field of PUR floor curing, in particular to a high-efficiency curing machine for processing PUR floor. Background Art

[0002] According to the existing information, a high-efficiency curing machine for PUR floor processing refers to a device specially designed for the processing of PUR floor, which can quickly and evenly cure the PUR coating or adhesive layer. This curing machine usually uses one or more curing technologies, such as ultraviolet UV curing, infrared IR heating or hot air circulation, to accelerate the chemical reaction process of PUR materials, so as to achieve complete curing of the coating in a short time.

[0003] The existing authorized patents and existing equipment with the same technology and similar technology equipment of the same type still have the following problems in daily use:

[0004] Traditional PUR floor high-efficiency curing machines mostly use ultraviolet curing when curing. When the floor enters the ultraviolet area, the floor will age after contact with ultraviolet rays. Aging will cause the physical and chemical properties of the material to deteriorate. Usually, ultraviolet absorbers are applied to the floor to prevent excessive contact between ultraviolet light and the floor surface, which will cause yellowing and aging. Traditional high-efficiency curing machines are prone to uneven application of ultraviolet absorbers when applying ultraviolet absorbers. Uneven application will form spots or stripes on the floor surface, affecting the appearance of the floor. At the same time, uneven application will cause the absorbent concentration in some areas to be too low, which cannot effectively protect against ultraviolet rays, thereby accelerating the aging of the floor.

[0005] At the same time, the PUR coating is poured on the floor that is sent into the curing chamber. Due to improper operation during the pouring process, the PUR coating on the floor is unevenly distributed and bubbles are generated. After curing, the floor surface will have different shades of color, and there will be visual defects such as mottled and striped, which seriously affect the aesthetics of the floor. At the same time, the bubbles will form bulges or depressions after curing, further destroying the flatness and overall appearance of the floor. In addition, the bubbles after curing will destroy the continuity of the PUR coating, causing the coating to easily produce stress concentration in these areas when subjected to force, thereby reducing the coating's wear resistance, weather resistance, and compression resistance. Summary of the invention

[0006] The purpose of this application is to solve or at least alleviate the problems existing in the prior art.

[0007] In order to solve the above shortcomings, the present invention provides the following technical solutions: an efficient curing machine for PUR floor processing, comprising an installation and placement table, the top of which is symmetrically distributed and fixedly connected with fixed plates, the sides of the fixed plates close to each other are rotatably connected with rollers, the surfaces of the two fixed plates are connected with conveyor belts for transmission, the centers of the tops of the two fixed plates are fixedly connected with curing bins, and the curing bins are provided with control components and auxiliary components;

[0008] The control assembly includes sliding rods, which are symmetrically distributed and slidably connected to the interior of the curing chamber. The control assembly is used to spray pur paint and ultraviolet absorber on the floor and shake them evenly;

[0009] The auxiliary component comprises a scraping and collecting plate, which is fixedly connected to the inner wall of the curing chamber. The auxiliary component is used to smooth and scrape the paint on the floor after spraying and to remove bubbles on the floor surface.

[0010] Furthermore, the control component also includes a return spring, which is symmetrically distributed and sleeved on the surface of the sliding rod. The two sliding rods are fixedly connected to a force block at one end away from the curing bin, one end of the two return springs is fixedly connected to the inner wall of the curing bin, and the other end of the two return springs is fixedly connected to the force block.

[0011] Furthermore, one end of the two sliding rods located outside the curing chamber is fixedly connected to a control rod, one end of the two control rods away from the sliding rods is rotatably connected to a first rotating plate, and the bottoms of the two first rotating plates are fixedly connected to a rotating rod.

[0012] Furthermore, the top of the curing bin is symmetrically distributed and fixedly connected to a supporting platform, the two supporting platforms are fixedly connected to liquid storage bins, the two rotating rods pass through the liquid storage bins, the two rotating rods are rotatably connected to the liquid storage bins, and the bottoms of the two liquid storage bins are fixedly connected to connecting pipes.

[0013] Furthermore, the surface of one of the fixed plates is rotatably connected to a second rotating plate, a transmission belt is connected between the second rotating plate and the roller, a transmission rod is rotatably connected to the surface of the second rotating plate, and an end of the transmission rod away from the second rotating plate is rotatably connected to a third rotating plate.

[0014] Furthermore, one end of the third rotating plate away from the transmission rod is fixedly connected to a rotating block, and a connecting rod is slidably connected inside the rotating block.

[0015] Furthermore, a fixed block is fixedly connected to the inner wall of the solidification bin, the top of the fixed block is rotatably connected to a shaking bin, the ends of the two connecting pipes away from the liquid storage bin are both connected to the shaking bin, the shaking bin is rotatably connected to the connecting rod, and the bottom of the shaking bin is fixedly connected to a liquid injection bin.

[0016] Furthermore, the auxiliary component also includes a flow hole, which is opened on the scraping and collecting plate, and the scraping and collecting plate is fixedly connected to a flow pipe on one side away from the liquid injection bin, and the curing bin is fixedly connected to a sandpaper on one side close to the flow pipe.

[0017] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0018] 1. This device is provided with a shaking bin, so that the PUR coating and ultraviolet absorber stored in the liquid storage bin drive the rotating rod to produce a rotating contact blockage as the floor enters the curing bin, and the two liquids enter the shaking bin. At the same time, the shaking of the shaking bin makes the PUR coating and ultraviolet absorber evenly mixed, so that when the mixed PUR coating and ultraviolet absorber are applied to the floor surface, it is possible to avoid the uneven distribution of the two liquids causing some floors to be mottled after curing. In addition, a protective film can be formed on the floor surface to increase the anti-aging performance of the floor. After the two liquids are applied to the surface of the floor through the liquid injection bin, the PUR coating with highly uneven distribution on the floor surface can be filled, which can effectively eliminate the unevenness of the floor surface and make the floor smoother, thereby improving the overall aesthetics. At the same time, by applying the ultraviolet absorber, the floor can be prevented from direct contact with ultraviolet rays, and the aging and yellowing of the coating can be avoided during the curing process.

[0019] 2. At the same time, by setting up a scraping and collecting plate, after the floor surface is sprayed with PUR paint and ultraviolet absorber, when the floor moves to the scraping and collecting plate, the excess paint on the floor surface is scraped and collected through the oblique design of the front end of the scraping and collecting plate. Collecting and properly handling the excess paint on the surface can avoid waste and reduce material loss, so that the collected paint can be reused, and uneven curing caused by excessively thick paint on the floor surface can be avoided, ensuring the uniformity and quality of the coating, while further avoiding the generation of bubbles, which can enhance the bonding strength between the coating and the substrate, making the floor more durable, while maintaining stable performance of the floor and reducing the frequency of repairs and replacements.

[0043] Compared with existing authorized patents, equipment with the same technology, and equipment with similar technology of the same type, the following effects are achieved: the PUR coating and the UV absorber are evenly mixed and applied to the floor surface to avoid the mottled phenomenon caused by uneven distribution, and at the same time, the PUR coating with different thicknesses on the floor surface is filled and scraped off.

[0044] In other aspects, this embodiment also provides an efficient curing machine for PUR floor processing, such as Figure 1-Figure 8 As shown, the auxiliary component 300 also includes a circulation hole 302, and the circulation hole 302 is opened on the scraper collection plate 301. It should be noted that the front end of the scraper collection plate 301 is an inclined surface, and the side of the scraper collection plate 301 away from the liquid injection bin 216 is fixedly connected to the circulation tube 303, and the side of the curing bin 105 close to the circulation tube 303 is fixedly connected to the sandpaper 304.

[0045] Compared with existing authorized patents, equipment with the same technology, and equipment with similar technology of the same type, the following effects are achieved: it enables the excess paint on the floor surface to be scraped off and collected, and the collection and proper disposal of the excess paint on the surface can avoid waste, reduce material loss, and further avoid the generation of bubbles, thereby enhancing the bonding strength between the coating and the substrate.

[0046] The complete working principle and working process of the above embodiment are as follows:

[0047] The roller 103 is electrically connected to the external power supply. When the operator starts the external power supply, the roller 103 rotates as the external power supply is started. The conveyor belt 104 is transmission-connected to the roller 103. When the roller 103 rotates, the conveyor belt 104 rotates as the roller 103 rotates. At this time, the floor at the top of the conveyor belt 104 is gradually transported toward the direction close to the curing bin 105 as the conveyor belt 104 rotates. When it enters the interior of the curing bin 105, since the floor has a certain weight, it conflicts with the inclined surface of the force block 203 after entering the interior of the curing bin 105. As the conveyor belt 104 continues to rotate, the floor pushes the force block 203 away from each other, and the reset spring 202 and the force block 20 3 is fixedly connected. At this time, the force-bearing block 203 is squeezed by the force-bearing block 203 and shrinks in the direction close to the solidification chamber 105. The sliding rod 201 is fixedly connected to the force-bearing block 203. The sliding rod 201 is pushed by the force-bearing block 203 and moves in the direction away from each other. The control rod 204 is fixedly connected to the sliding rod 201. The control rod 204 moves with the movement of the sliding rod 201. The first rotating plate 205 is rotationally connected to the control rod 204. When the control rod 204 moves, the first rotating plate 205 is driven to rotate with the connection between it and the liquid storage chamber 208 as the axis. The rotating rod 206 is fixedly connected to the first rotating plate 205. When the first rotating plate 205 rotates, the rotating rod 206 rotates with the rotation of the first rotating plate 205. The rotation causes the rotating rod 206 to gradually move away from the connection between the liquid storage tank 208 and the connecting pipe 218 during the rotation process, so that the rotating rod 206 loses the blockage of the connecting pipe 218. The two liquid storage tanks 208 are respectively filled with PUR coating and ultraviolet absorber. When the rotating rod 206 loses the blockage of the connecting pipe 218, the PUR coating and ultraviolet absorber flow into the shaking tank 209 along the connecting pipe 218. The transmission belt 210 is connected to the roller 103 for transmission. When the roller 103 rotates, the transmission belt 210 transmits the force generated by the rotation of the roller 103 to the second rotating plate 211, so that the second rotating plate 211 rotates with the rotation of the roller 103. The transmission rod 212 is rotationally connected to the second rotating plate 211. When the second rotating plate 211 rotates, the transmission rod 212 rotates with the rotation of the second rotating plate 211, and the third rotating plate 213 is rotationally connected to the transmission rod 212. When the transmission rod 212 rotates, the third rotating plate 213 rotates with the rotation of the transmission rod 212. The rotating block 214 is fixedly connected to the third rotating plate 213. When the third rotating plate 213 rotates, the third rotating plate 213 rotates with the rotation of the rotating block 214. The connecting rod 215 is slidably connected to the rotating block 214. When the rotating block 214 rotates, the rotating block 214 slides on the surface of the connecting rod 215, and the rotating block 214 drives the connecting rod 215 to rotate synchronously. The shaking bin 209 is rotationally connected to the connecting rod 215, as shown in FIG. Figure 8When the rotating block 214 rotates to the right, the connecting rod 215 moves with the rotation of the rotating block 214, thereby driving the shaking bin 209 to tilt in the direction away from the rotating block 214. When the rotating block 214 rotates to the left, the connecting rod 215 moves with the rotating block 214, driving the shaking bin 209 to tilt in the direction close to the rotating block 214. Since the rotating block 214 continues to rotate, the shaking bin 209 swings around the connection between it and the fixed block 217 as the axis, and the PUR coating and ultraviolet absorber injected into it through the connecting pipe 218 are evenly shaken. There are holes on the shaking bin 209 and the fixed block 217. When the two holes are Correspondingly, the liquid shaken evenly inside the shaking bin 209 flows into the liquid injection bin 216 along the fixed block 217. Since a roller is arranged inside the liquid injection bin 216, when the floor contacts the roller inside the liquid injection bin 216, the roller is caused to rotate, and the PUR coating and ultraviolet absorber shaken evenly inside the liquid injection bin 216 are applied to the top of the floor, and the PUR coating with uneven height distribution on the floor surface is filled. At the same time, the ultraviolet thinner is applied to prevent the floor from aging and yellowing during the curing process, which helps to maintain the original color and glossiness of the coating, and can ensure that the floor remains beautiful for a long time, and enhance the visual effect of the overall space.

[0048] When the floor continues to move to the scraper collection plate 301 with the conveyor belt 104, the inclined surface set at the front end of the scraper collection plate 301 scrapes off the excess PUR coating and ultraviolet absorber on the surface of the wooden board to avoid excessive coating and uneven curing effect. The circulation tube 303 is fixedly connected to the scraper collection plate 301, and the scraped PUR coating and ultraviolet absorber flow out of the curing chamber 105 through the circulation tube 303 and flow to the box body connected to the tail end of the circulation tube 303 to be collected, so that the collected coating can be reused. The sandpaper 304 is fixedly connected to the curing chamber 105. When the wooden board moves out of the curing chamber 105 with the conveyor belt 104, the sandpaper 304 can polish the surface of the curing chamber 105. At the same time, the scraping of the floor by the scraper collection plate 301 can also avoid the generation of bubbles, enhance the bonding force between the coating and the substrate, make the floor more sturdy and durable, and at the same time maintain the stability of the performance of the floor and reduce the frequency of maintenance and replacement.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
