Description

Technical Field

[0001] This utility model relates to the field of stone plastic flooring production technology, specifically a UV roller coating and curing device for stone plastic flooring production. Background Technology

[0002] Stone plastic flooring, also known as stone plastic floor tiles, is formally called "PVC sheet flooring." It is a new type of high-quality, high-tech floor decoration material. It uses stone powder to form a solid base layer with a high-density, high-fiber mesh structure, and the surface is covered with a super wear-resistant polymer PVC wear-resistant layer. The material coated on the floor surface needs to be shaped and solidified by a curing device to make the coating firmly bonded to the base plate as a whole.

[0003] Existing UV roller coating and curing equipment for stone plastic flooring production automatically transports the flooring onto a conveyor belt and irradiates it with curing lamps, forming an automated curing production line. However, in this curing production line, the curing lamps are fixed in installation, meaning the height of the curing lamps is fixed. When transporting and irradiating different types and thicknesses of flooring, the different thicknesses of the boards mean that the height of the board surface from the curing lamp is also different. These different height intervals affect the irradiation intensity of the curing lamp light, resulting in inconsistent curing effects for boards of different thicknesses and affecting the curing quality.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a UV roller coating and curing device for the production of stone plastic flooring. Utility Model Content

[0005] The purpose of this invention is to provide a UV roller coating and curing device for the production of stone plastic flooring, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a UV roller coating curing device for stone plastic flooring production, comprising a curing chamber, a door panel rotatably connected to the right side of the outer surface of the curing chamber, an adjustment plate provided inside the curing chamber, a groove provided in the middle of the upper surface of the adjustment plate, curing lamps uniformly distributed and fixedly installed on the lower surface of the adjustment plate, an adjustment mechanism provided on the inner surface of the groove, and air holes uniformly distributed on the surface of the adjustment mechanism at the installation gap of the curing lamps.

[0007] Preferably, the adjustment mechanism includes a bidirectional lead screw rotatably connected to the inner surface of the groove, a handle fixedly connected to the right end of the bidirectional lead screw through the adjustment plate, adjustment seats threadedly connected to both the left and right sides of the surface of the bidirectional lead screw, and movable rods rotatably connected to the upper surface of the adjustment seats.

[0008] Preferably, the surface of the adjusting seat slides in contact with the inner surface of the groove, and the upper end of the movable rod is rotatably connected to the upper surface of the curing box via the same rotating shaft seat.

[0009] Preferably, multiple air inlet pipes are fixedly connected to both sides of the outer surface of the curing box, and the same delivery pipe is fixedly connected to the upper opposite end of each of the air inlet pipes on both sides.

[0010] Preferably, a connecting pipe is fixedly installed on the rear side of the middle part of the surface of the conveying pipe, and an air pump is fixedly connected to the rear end of the connecting pipe, and the air pump is fixedly connected to the upper side of the outer surface of the curing box.

[0011] Preferably, a frame is fixedly installed on the lower surface of the curing box, and a conveyor belt is installed on the inner surface of the frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of an adjusting plate, groove, adjusting mechanism, bidirectional lead screw, handle, adjusting seat, and movable rod, ensures that the distance of the curing lamp is the same when irradiating the surface of the board with different thicknesses, thus guaranteeing the uniformity of the curing effect. It prevents different curing performances from occurring when the curing lamp is irradiated from a fixed position on the board with different thicknesses, as the lamp position remains unchanged. The device can adjust the irradiation distance according to the thickness of the board during curing, ensuring the uniformity and quality of curing.

[0014] 2. This utility model, through the arrangement of air vents, air inlet pipes, conveying pipes, connecting pipes, and an air pump, allows the air pump to draw in gas from inside the curing chamber via the connecting pipes, conveying pipes, and air inlet pipes. Gas located below the regulating plate in the curing chamber can rise through the air vents and enter the air inlet pipes for extraction and discharge. As the overall air inside the curing chamber is continuously drawn in, fresh air from the outside continuously flows in. This influx of fresh air ensures that the temperature inside the curing chamber remains constant and cools the curing lamp, preventing the curing lamp from generating high temperatures during continuous operation and preventing high-temperature accumulation inside the curing chamber, which could lead to temperature changes and affect the curing effect. It can maintain a constant temperature and dissipate high temperatures, thereby ensuring the quality and effect of curing. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-3 As shown, a UV roller coating curing device for the production of stone plastic flooring includes a curing box 1. A door panel 2 is rotatably connected to the right side of the outer surface of the curing box 1. An adjustment plate 3 is provided inside the curing box 1. A groove 4 is provided in the middle of the upper surface of the adjustment plate 3. Curing lamps 5 are evenly distributed and fixedly installed on the lower surface of the adjustment plate 3. An adjustment mechanism 6 is provided on the inner surface of the groove 4. Air holes 7 are evenly distributed on the surface of the adjustment mechanism 6 at the installation gap of the curing lamps 5.

[0021] By adopting the above technical solution, the coating on the surface of the board is cured by the curing lamp 5;

[0022] The vent 7 allows the gas on the lower side of the regulating plate 3 and the heat generated by the curing lamp 5 to rise and dissipate.

[0023] The door panel 2 can be opened from the side to open the curing box 1, thereby adjusting the adjustment mechanism 6.

[0024] Furthermore, the adjustment mechanism 6 includes a bidirectional lead screw 601 rotatably connected to the inner surface of the groove 4. The right end of the bidirectional lead screw 601 passes through the adjustment plate 3 and is fixedly connected to a handle 602. Adjustment seats 603 are threadedly connected to both the left and right sides of the surface of the bidirectional lead screw 601. Movable rods 604 are rotatably connected to the upper surface of the adjustment seats 603.

[0025] The surface of the adjusting seat 603 slides and fits against the inner surface of the groove 4, and the upper end of the movable rod 604 is rotatably connected to the upper surface of the curing box 1 via the same rotating shaft seat.

[0026] By adopting the above technical solution, the bidirectional lead screw 601 can be rotated manually through the handle 602. At this time, the adjusting seat 603 will not rotate with the bidirectional lead screw 601 under the limit of the groove 4, but will only be moved by the thread force.

[0027] When the adjusting seat 603 moves in opposite directions, it will cause the bottom ends of the movable rods 604 to move closer to each other, while the upper end of the movable rods 604 remains fixed and the length of the movable rods 604 also changes. When the movable rods 604 move closer, their vertical height will extend, thereby pushing the adjusting plate 3 to move downward, which can adjust the curing lamp 5 downward. Conversely, when the adjusting seat 603 moves in the opposite direction, it can pull the adjusting plate 3 upward, which can raise the curing lamp 5 upward.

[0028] Furthermore, multiple air inlet pipes 8 are fixedly connected to both sides of the outer surface of the curing box 1, and the same delivery pipe 9 is fixedly connected to the upper opposite end of each of the left and right air inlet pipes 8.

[0029] By adopting the above technical solution, the air inlet pipe 8 allows the air inside the curing chamber 1 to enter the delivery pipe 9.

[0030] Furthermore, a connecting pipe 10 is fixedly installed on the rear side of the middle part of the surface of the conveying pipe 9, and a vacuum pump 11 is fixedly connected to the rear end of the connecting pipe 10, and the vacuum pump 11 is fixedly connected to the upper side of the outer surface of the curing box 1.

[0031] By adopting the above technical solution, the air pump 11 can draw gas from inside the curing chamber 1 using the connecting pipe 10, the delivery pipe 9 and the air inlet pipe 8.

[0032] Furthermore, a frame 12 is fixedly installed on the lower surface of the curing box 1, and a conveyor belt 13 is installed on the inner surface of the frame 12.

[0033] By adopting the above technical solution, the conveyor belt 13 can automatically transport the floor into the curing box 1, and in conjunction with the curing lamp 5, perform curing processing. Working Principle: When using the UV roller coating curing device for stone plastic flooring production, firstly, the conveyor belt 13 is started. The flooring is placed on the conveyor belt 13 and automatically conveyed into the curing chamber 1. After being irradiated by the curing lamp 5, the surface coating is cured and sent out. During the curing process, the air pump 11 uses the connecting pipe 10, conveying pipe 9, and air inlet pipe 8 to draw gas from inside the curing chamber 1. The gas in the curing chamber 1 located below the regulating plate 3 can rise through the air hole 7 and enter the air inlet pipe 8 for extraction and discharge. As the overall air inside the curing chamber 1 is continuously drawn in, fresh air from the outside will continuously flow in. The influx of fresh air ensures that the temperature inside the curing chamber 1 remains constant and can cool the curing lamp 5, preventing the curing lamp 5 from generating high temperatures during continuous operation and preventing high-temperature accumulation inside the curing chamber 1, which would cause temperature changes and affect the curing effect. Depending on the thickness of the board, before conveying and processing, the door plate 2 can be opened, and the bidirectional screw 601 can be manually rotated through the handle 602. When the adjusting seat 603 is limited by the groove 4, it will not rotate with the bidirectional lead screw 601. It will only move under the force of the thread. When the adjusting seat 603 moves in opposite directions, it will drive the bottom of the movable rod 604 to move closer to each other. The upper end of the movable rod 604 remains fixed, and the length of the movable rod 604 also changes. When the movable rod 604 moves closer, its vertical height will extend, thereby pushing the adjusting plate 3 to move downward, which can adjust the curing lamp 5 downward. Conversely, the adjusting seat 603 moves in the opposite direction, which can pull the adjusting plate 3 upward, that is, pull the curing lamp 5 upward. In this way, the irradiation height of the curing lamp 5 can be adjusted according to the different thicknesses of the board. This adjustment ensures that the distance of the curing lamp 5 irradiating the surface of the board with different thicknesses is the same, which ensures the uniformity of the curing effect. It prevents the different curing performance of the board with different thicknesses under the irradiation of the curing lamp 5 in a fixed position because the lamp position remains unchanged. This is the working principle of the UV roller coating curing device for stone plastic flooring production.
