Description

Technical Field

[0001] This utility model belongs to the technical field of flooring production equipment, specifically relating to a uniform scraping device for coating a high-strength alloy flooring reinforcing layer. Background Technology

[0002] High-strength alloy flooring typically comprises multiple functional layers, such as a base layer, a wear-resistant layer, a reinforcing layer, and a filler layer. During manufacturing, each functional layer needs to be sequentially coated onto the base layer. The reinforcing layer is generally a liquid material composed of epoxy resin, modified acrylic resin, nano-calcium carbonate, flame retardants, and anti-aging agents. Current technologies for coating the reinforcing layer during flooring production suffer from problems such as poor coating uniformity and low coating efficiency, failing to meet production requirements. Therefore, there is an urgent need for a uniform coating device for the reinforcing layer of high-strength alloy flooring to solve these technical problems. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a uniform coating device for high-strength alloy floor reinforcement layers. The device includes a conveyor, a gantry frame on the conveyor frame, and a coating assembly on the gantry frame. The coating assembly includes a vertical telescopic rod, a connecting plate, a first guide pipe, a second guide pipe, and a coating plate. The vertical telescopic rod is an electric push rod or a hydraulic rod. The fixed end of the vertical telescopic rod is fixed to the gantry frame. The telescopic end of the vertical telescopic rod is vertically downward and fixedly connected to the first vertical guide pipe. The first guide pipe is connected to an inlet pipe. The lower end of the first guide pipe is fixedly connected to the connecting plate. The second guide pipe is rotatably connected to the connecting plate via a bearing. The upper end of the second guide pipe is connected to the first guide pipe via a rotary joint. The coating plate is fixedly connected to the lower end of the second guide pipe. The coating plate has a material-holding cavity that communicates with the second guide pipe. The lower surface of the coating plate has multiple outlet holes communicating with the material-holding cavity. The coating blade is circular, and a gear one is fixed on the second feed pipe. The first gear meshes with a second gear, which is connected to a motor fixed on a connecting plate. The material to be coated enters the first feed pipe, the second feed pipe, and the material holding chamber sequentially from the feed pipe, and then exits from the discharge hole. It is then coated by the coating blade onto the floor conveyed by the conveyor below. The motor drives the second gear to rotate, which meshes with the first gear, causing the second feed pipe to rotate, thereby rotating the coating blade for efficient and uniform coating.

[0004] Preferably, the plurality of discharge holes are arranged in a spiral pattern (Archimedean spiral) on the scraper plate. This arrangement allows for more comprehensive and uniform coating of the material as the scraper plate rotates.

[0005] Preferably, the material holding chamber is equipped with multiple partitions, which divide the material holding chamber into multiple sub-chambers. Each sub-chamber is connected to a guide pipe via a guide branch pipe, and the guide branch pipe is equipped with a switch valve. This design allows for flexible adjustment of the discharge range of the discharge hole as needed, matching the coating of different sized flooring, avoiding material waste, and improving equipment utilization.

[0006] Preferably, the lower surface of the coating blade is provided with multiple scraping ridges along the radial direction. The scraping ridges can perform a uniform coating operation on the material being coated when the coating blade rotates, making the coating more uniform.

[0007] Preferably, a protruding discharge head is fixedly connected to the lower end of the discharge hole.

[0008] Preferably, the conveyor is equipped with a limiting component, which includes two cooperating clamps located on opposite sides of the conveyor. The two clamps are connected to two synchronous horizontal telescopic rods, which are either electric push rods or hydraulic rods. The fixed ends of the two horizontal telescopic rods are connected to the frame of the conveyor on their respective sides. This effectively secures the floor to be coated, preventing movement during coating and improving the coating effect.

[0009] Preferably, the coating scraper is equipped with an infrared sensor. The infrared sensor is connected to a controller, which is electrically connected to the conveyor, the vertical telescopic rod, and the horizontal telescopic rod. Upon sensing the floor surface via the infrared sensor, the controller stops the conveyor, extends the horizontal telescopic rod to clamp the floor surface to be coated, and extends the vertical telescopic rod, causing the coating scraper to move downwards to contact the floor surface and perform the coating operation.

[0010] This invention also includes other components that enable the uniform coating device for applying a high-strength alloy floor reinforcement layer to function properly, such as motor control components, conveyor control components, vertical telescopic rod control components, feed pump connected to the feed pipe, and storage tank (mixing tank), etc., all of which are conventional technologies and equipment in the field. Furthermore, devices or components not limited in this invention, such as partitions, discharge heads, switching valves, scraper ridges, bearings, controllers (PLCs), electric actuators, hydraulic rods, infrared sensors, etc., all employ conventional technologies and equipment in the field.

[0011] Working principle: The flooring to be coated is placed on the conveyor surface of the conveyor in sequence and transported by the conveyor to the area below the coating plate. The conveyor stops conveying, the vertical telescopic rod extends, and the coating plate moves down to contact the flooring. The material to be coated enters the feed pipe in sequence through the guide pipe 1, guide pipe 2, and the material holding chamber, and is discharged from the discharge hole. It is then coated by the coating plate onto the flooring transported by the conveyor below.

[0012] This invention has the following advantages: it can perform efficient and continuous coating operations on the floor, improves the uniformity of coating, has a good coating effect and high efficiency, is suitable for coating various liquid coatings in floor production, has high equipment utilization, and is beneficial to production.

Detailed Implementation

[0016] The present invention will now be clearly described with reference to the accompanying drawings and specific embodiments. This description is merely for explaining the present invention and is not intended to limit it. Any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art based on the embodiments of the present invention without inventive effort to obtain all other embodiments should be included within the protection scope of the present invention.

[0017] Example 1 like Figure 1-3As shown, this utility model provides a uniform coating device for high-strength alloy floor reinforcement layers, including a conveyor 1. A gantry frame 2 is mounted on the frame of the conveyor 1, and a coating assembly is mounted on the gantry frame 2. The coating assembly includes a vertical telescopic rod 3, a connecting plate 9, a first guide pipe 8, a second guide pipe 13, and a coating plate 4. The vertical telescopic rod 3 is an electric push rod or a hydraulic rod. The fixed end of the vertical telescopic rod 3 is fixed to the gantry frame 2, and the telescopic end of the vertical telescopic rod 3 points vertically downward and is fixedly connected to a vertical guide pipe 8. 8 is connected to a feed pipe 7, which is connected to a mixing tank 5 containing the coating material. A feed pump 6 is also connected to the feed pipe 7. The lower end of the first guide pipe 8 is fixedly connected to a connecting plate 9. The second guide pipe 13 is rotatably connected to the connecting plate 9 through a bearing. The upper end of the second guide pipe 13 is connected to the first guide pipe 8 through a rotary joint. The scraper plate 4 is fixedly connected to the lower end of the second guide pipe 13. The scraper plate 4 has a material holding cavity inside, which is connected to the second guide pipe 13. The lower surface of the scraper plate 4 has multiple discharge holes 14 that are connected to the material holding cavity.

[0018] The material to be coated enters sequentially from the feed pipe 7 into the guide pipe 1 8, the guide pipe 2 13, and the material holding chamber, and is then discharged from the discharge hole 14. It is then coated by the scraper plate 4 onto the floor conveyed by the conveyor 1 below.

[0019] The coating blade 4 is circular, and a gear 10 is fixed on the guide tube 13. The gear 10 meshes with a gear 12, which is connected to a motor 11, which is fixed on the connecting plate 9. The motor 11 drives the gear 12 to rotate, and the gear 12 meshes with the gear 10, which in turn drives the guide tube 13 to rotate, thereby rotating the coating blade 4 for efficient and uniform coating.

[0020] The multiple discharge holes 14 are arranged in a spiral pattern (Archimedean spiral) on the scraper plate 4. This arrangement allows for more comprehensive and uniform coating of the material when the scraper plate 4 rotates.

[0021] Example 2 like Figure 1 , 4 As shown in Figure 5, the difference between this embodiment and Embodiment 1 is that the material holding chamber is provided with multiple annular, concentric partitions 16, which divide the material holding chamber into multiple sub-chambers. These sub-chambers are connected to the second material guide pipe 13 via guide branch pipes 15, and each guide branch pipe 15 is equipped with a switch valve. This design allows for flexible adjustment of the discharge range of the discharge hole as needed, matching the coating of different sized flooring, avoiding material waste, and improving equipment utilization.

[0022] Specifically, when the coated floor is large, all the valves on the feed pipes are opened, and the coating area is at its maximum. When the coated floor is small, the valves on the feed pipes of the outermost, second outermost, etc., can be closed in sequence according to the size of the floor, and only the valves on the feed pipes of the corresponding compartment of the floor are opened, which reduces material waste during the coating process and saves resources.

[0023] Example 3 like Figure 1 , 2 As shown in Figure 6, the difference between this embodiment and Embodiment 1 is that the lower surface of the scraper plate 4 is provided with multiple scraping ridges 17 along the radial direction. The scraping ridges 17 can perform a uniform coating operation on the material being coated when the scraper plate 4 rotates, making the coating more uniform.

[0024] Example 4 like Figure 1 , 7 As shown, the difference between this embodiment and Embodiment 1 is that the conveyor 1 is equipped with a limiting component. The limiting component includes two cooperating clamps 18, which are respectively located on both sides of the conveyor 1. The two clamps 18 are connected to two synchronous horizontal telescopic rods 19, which are either electric push rods or hydraulic rods. The fixed ends of the two horizontal telescopic rods 19 are respectively connected to the frame of the conveyor 1 on the corresponding side. The height of the clamps is not greater than the thickness of the floor. During coating, the scraper does not contact the clamps, thus not affecting the coating process. This arrangement effectively fixes the floor to be coated, preventing the floor from moving during coating and improving the coating effect.

[0025] Example 5 like Figure 1 , 7 As shown, the difference between this embodiment and Embodiment 4 is that the coating plate 4 is equipped with an infrared sensor. The infrared sensor is connected to a controller, which is electrically connected to the conveyor 1, the vertical telescopic rod 3, and the horizontal telescopic rod 19. Upon sensing the floor using the infrared sensor, the controller stops the conveyor 1, extends the horizontal telescopic rod 19 to clamp the floor to be coated, extends the vertical telescopic rod 3, and the coating plate 4 moves down to contact the floor, performing the coating operation. The connection and control of the controller with other components are existing technology and pertain to control methods; please refer to the principle specification or user manual for details, which will not be elaborated here.

[0026] Example 6 like Figure 1 , 2As shown in Figure 6, the difference between this embodiment and Embodiment 3 is that a protruding discharge head is fixedly connected to the lower end of the discharge hole 14. The height of the discharge head is not higher than the height of the scraping ridge. This feature improves the discharge efficiency and, in conjunction with the scraping ridge, enhances the scraping effect.

[0027] The conveyor (which may be a belt conveyor), motor, infrared sensor (which may be an Omron E3Z-LS61), electric actuator, hydraulic actuator, controller, etc. in the above implementation examples are conventional equipment in this field and are existing technologies. This application does not improve their principles but only utilizes their existing functions. For their specific structure and principles, please refer to the product manual or existing technical data, which will not be repeated here.

[0028] The embodiments of this utility model have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
