Abstract
Description
Technical Field
[0001] This utility model relates to the field of flooring production technology, and in particular to a device for uniformly coating three-layer flooring with bio-based adhesive. Background Technology
[0002] The bio-based adhesive three-layer flooring uniform coating device is designed to solve the problem of uneven adhesive coating when laminating three-layer flooring (top layer, core layer, and bottom layer). Its core advantage lies in ensuring uniform coverage of bio-based adhesives (such as starch-based and protein-based adhesives) on different flooring substrates through precise quantity control, multi-station collaboration, and adaptive adjustment, thereby improving composite strength and reducing adhesive waste.
[0003] Floor uniform coating equipment is a specialized device used to precisely apply adhesives, coatings, or moisture-proof layers to the surface or interlayer of floor substrates (such as solid wood, composite boards, PVC boards, etc.). Its core function is to ensure the bonding strength, surface quality, and durability of the floor by controlling the amount of adhesive applied and achieving a uniform coating effect, while reducing material waste. The initial investment of a set of automatic coating equipment (including adhesive supply, coating, and control systems) is usually between 500,000 and 2 million yuan, and the replacement cost of core components (such as imported metering pumps and servo motors) is high (approximately 10,000 to 30,000 yuan for a single metering pump). Due to limited production capacity, small and medium-sized flooring factories have a long payback period of 2 to 3 years for equipment investment.
[0004] The existing floor uniform coating devices have the following drawbacks: most are designed for standard-sized flooring (such as 1220×180mm) and conventional adhesives (such as urea-formaldehyde resin). If producing ultra-narrow flooring (such as 300×150mm) or high-viscosity bio-based adhesives (such as modified starch adhesive), the coating head needs to be replaced. The replacement process is cumbersome, resulting in a changeover time of 1-2 hours, which affects processing efficiency. Therefore, a three-layer floor uniform coating device for bio-based adhesives is proposed to solve the above problems. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides a three-layer uniform coating device for bio-based adhesives, which aims to improve the problem in the prior art that the coating head needs to be replaced when producing ultra-narrow floorboards or high-viscosity bio-based adhesive materials.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a three-layer floor uniform coating device for bio-based adhesives, comprising a conveying platform and a support frame. The support frame is fixedly installed on the front and rear outer walls of the conveying platform. The top outer wall of the conveying platform contacts the main body of the flooring board. A lifting frame is fixedly connected to the rear outer wall of the support frame. An adjustment mechanism is provided on the lifting frame. An auxiliary mechanism is provided on the adjustment mechanism. The adjustment mechanism includes a frame. The frame is fixedly installed at the output end of the lifting frame. A rotating column is rotatably connected to the front and rear inner walls of the frame via bearings. An assembly operating frame is fixedly connected to the side outer wall of the rotating column. An installation frame is snapped onto the side outer wall of the assembly operating frame. A multi-module coating head is fixedly connected to the side outer wall of the installation frame. A slot is opened on the rear outer wall of the frame. A polygonal plate is slidably connected to the rear inner wall of the rotating column. A compression spring is fixedly connected to the rear outer wall of the polygonal plate.
[0007] As a further description of the above technical solution: the auxiliary mechanism includes a mounting groove, which is opened on the outer side wall of the assembly operating frame. The outer front wall of the assembly operating frame has a through hole, and a threaded rod is threadedly connected to the inner wall of the inner ring of the through hole. An adjusting plate is fixedly connected to the front end of the threaded rod, and a directional mark is opened on the outer front wall of the adjusting plate.
[0008] As a further description of the above technical solution: the frame is slidably connected to the inner front wall of the lifting frame, and the assembly operating frame passes through the outer front and rear walls of the frame.
[0009] As a further description of the above technical solution: there are a plurality of mounting brackets, which are annularly snapped onto the outer side wall of the assembly operating frame; there are a plurality of multi-module coating heads, which are respectively fixedly connected to the outer side wall of the mounting bracket.
[0010] As a further description of the above technical solution: silicone pads are fixedly connected to both the polygonal plate and the outer side wall of the slot; the polygonal plate is snapped into the inner rear wall of the slot; and the end of the compression spring away from the polygonal plate is fixedly connected to the inner rear wall of the rotating column.
[0011] As a further description of the above technical solution: the threaded rod is threadedly connected to the inner wall of the inner ring of the through hole, and the through hole penetrates the front inner wall of the mounting bracket.
[0012] As a further description of the above technical solution: the outer side wall of the adjustment disc is provided with grooves, and the front outer side wall of the directional mark is fixedly connected with a display coating.
[0013] This utility model has the following beneficial effects: 1. In this utility model, by setting a rotatable assembly operating frame and multiple ring-shaped mounting frames, multi-module coating heads of different specifications can be installed. When processing three-layer flooring of different specifications, simply pull the polygonal plate to separate it from the slot, and rotate the assembly operating frame to quickly switch the appropriate coating head. There is no need for cumbersome disassembly, which reduces the downtime during the adjustment process, ensures the uniformity of coating on wood of different specifications, and effectively improves work efficiency.
[0014] In this invention, by setting an adjustment disc with grooves, a directional mark indicating the coating, and a mating structure between a threaded rod and a through hole, when it is necessary to replace the coating head with a new specification or perform maintenance, the operator can rotate the adjustment disc according to the directional mark to separate the threaded rod from the through hole, and then pull the mounting bracket out of the mounting slot. This achieves convenient disassembly and assembly of the coating head, reduces the difficulty of operation, and provides convenience for equipment maintenance and upgrades.

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.
[0018] Reference Figures 1-3This utility model provides an embodiment of a three-layer flooring uniform coating device for bio-based adhesives, comprising a conveying platform 1 and a support frame 2. The support frame 2 is fixedly installed on the front and rear outer walls of the conveying platform 1. The top outer wall of the conveying platform 1 contacts the flooring board body 3. A lifting frame 4 is fixedly connected to the rear outer wall of the support frame 2. An adjustment mechanism 5 is provided on the lifting frame 4, and an auxiliary mechanism 6 is provided on the adjustment mechanism 5. The adjustment mechanism 5 includes a frame 51, which is fixedly installed on the output end of the lifting frame 4. The front and rear inner walls of the frame 51 are rotatably connected to rotating columns 52 via bearings, and the side outer walls of the rotating columns 52 are fixedly connected to... The assembly operating frame 53 is connected to a multi-mount bracket 54, which is used to install multiple multi-module coating heads 55 together to facilitate synchronous control of coating operations. The mounting bracket 54 is snapped onto the outer side wall of the assembly operating frame 53. The multi-module coating head 55 is fixedly connected to the outer side wall of the mounting bracket 54. The multi-module coating head 55 is a component that directly applies adhesive to the floor board body 3. Its multi-module design can achieve uniform coating. The rear outer wall of the frame 51 has a slot 56. The rear inner wall of the rotating column 52 is slidably connected to a polygonal plate 57. The rear outer wall of the polygonal plate 57 is fixedly connected to a compression spring 58.
[0019] Reference Figures 2-4 The frame 51 is slidably connected to the inner front wall of the lifting frame 4. The assembly operating frame 53 runs through the outer front and rear walls of the frame 51. There are several mounting frames 54, which are ring-shaped and snapped onto the outer side wall of the assembly operating frame 53. The ring distribution of multiple mounting frames 54 can install multiple multi-module coating heads 55 of different specifications, which facilitates quick switching of multi-module coating heads 55 according to different floor specifications. There are several multi-module coating heads 55, which are fixedly connected to the outer side wall of the mounting frame 54. Silicone pads are fixedly connected to the outer side walls of the polygonal plate 57 and the slot 56. The silicone pads can increase the friction between the polygonal plate 57 and the slot 56, making the connection more stable. The polygonal plate 57 is snapped onto the inner rear wall of the slot 56. The end of the compression spring 58 away from the polygonal plate 57 is fixedly connected to the inner rear wall of the rotating column 52.
[0020] Reference Figures 3-4The auxiliary mechanism 6 includes a mounting groove 61, which is formed on the outer side wall of the assembly operating frame 53. A through hole 62 is formed on the front outer wall of the assembly operating frame 53, providing a channel for the installation and threaded connection of the threaded rod 63, facilitating the fixing of the mounting frame 54 via the threaded rod 63. The inner wall of the through hole 62 is threaded with the threaded rod 63. An adjusting disc 64 is fixedly connected to the front end of the threaded rod 63. A pointing mark 65 is formed on the front outer wall of the adjusting disc 64, indicating the direction of the threaded rod 63. The tightness of the mounting bracket 54 allows operators to quickly determine whether it is securely fixed. The threaded rod 63 is threaded into the inner wall of the inner ring of the through hole 62, which penetrates the front inner wall of the mounting bracket 54. The outer side wall of the adjusting plate 64 has grooves to increase the friction between the hand and the adjusting plate 64 and prevent slippage when rotating the adjusting plate 64. The front outer wall of the pointing mark 65 is fixedly connected with a display coating, which makes the pointing mark 65 more conspicuous and easy for operators to observe and identify quickly.
[0021] Working principle: When processing three-layer flooring of different specifications, the polygonal plate 57 is pulled apart from the slot 56, and then the polygonal plate 57 is rotated to rotate the rotating column 52. The rotation of the rotating column 52 drives the assembly operating frame 53 to rotate, which in turn drives the mounting frame 54 to rotate. The rotation of the mounting frame 54 drives the multi-module coating head 55 to rotate, so that the multi-module coating head 55 adapted to the current specification of wood is aligned. This ensures the uniformity of coating for different specifications of wood and allows for quick adjustment of the coating head without cumbersome disassembly, reducing downtime and improving work efficiency. At the same time, when the multi-module coating head 55 is upgraded to a new specification of wood product or needs maintenance, the adjusting plate 64 is rotated according to the pointing mark 65, which drives the threaded rod 63 to rotate. The threaded rod 63 rotates and separates from the through hole 62. Then the mounting frame 54 is pulled out from the mounting slot 61, allowing for convenient disassembly, replacement or upgrade of the multi-module coating head 55.
[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
