Description

Technical Field

[0001] This utility model relates to the field of plastic flooring processing technology, and more specifically to a plastic flooring coating device. Background Technology

[0002] Plastic flooring is flooring made of plastic materials. It has the advantages of fast installation and fewer seams. Some plastic flooring is coated with UV adhesive to enhance its lifespan.

[0003] A search revealed Chinese patent CN222267630U, which discloses a UV coating apparatus for plastic flooring. This apparatus can coat plastic flooring of different thicknesses, effectively improving its applicability. However, during the coating process, a two-stage adhesion process is used to ensure the UV adhesive is evenly applied to the floor. When placing the UV adhesive on the leveling roller, it is crucial to ensure the adhesive completely covers the top of the roller. If the amount of adhesive is insufficient, the leveling roller may not be fully covered, resulting in gaps in the adhesive coverage. This affects the contact with the coating roller, leading to gaps in the adhesive on the coating roller and ultimately impacting the coating quality of the flooring. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a plastic floor coating device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a plastic floor coating device, including a frame, with a partition fixed between the inner walls of both sides of the frame by bolts, and two symmetrical fixing frames fixed to the top of the partition by bolts. A coating roller is rotatably connected between the two fixing frames via bearings. A motor for driving the coating roller is fixed to one side of one of the fixing frames by bolts. A first mounting frame is fixed to the top of the two fixing frames by bolts. A first cutter is fixed to the outer wall of one side of the first mounting frame by bolts. A liquid distribution frame is fixed between the inner walls of both sides of the first mounting frame by bolts. Multiple first and second liquid outlet holes are provided through the bottom of the liquid distribution frame. The tops of the multiple first and second liquid outlet holes are all connected to an external pipe connected to an external pump by threads. A height adjustment component for adjusting the floor height is provided on the inner wall of the bottom of the frame. A leveling component for secondary smoothing of UV adhesive is provided between the two fixing frames.

[0006] As a further embodiment of this utility model, the height adjustment component includes an electric push rod fixed to the bottom of the frame. The piston rod of the electric push rod is fixed to a support frame by bolts, and the top of the support frame passes through a partition and is slidably connected to the partition. Multiple support rollers are rotatably connected between the two sides of the top of the support frame through bearings.

[0007] As a further embodiment of this invention, the leveling assembly includes a smoothing roller that rotates between two fixed frames, and the bottom of the smoothing roller is flush with the bottom of the coating roller.

[0008] As a further embodiment of this utility model, a second mounting bracket is fixed to the top of the two fixed brackets by bolts, and a second cutter is fixed to one side of the second mounting bracket by bolts, and the second cutter is in contact with the smoothing roller.

[0009] As a further embodiment of this invention, the plurality of first liquid outlet holes and second liquid outlet holes are staggered, and the distance between two adjacent first liquid outlet holes is the same as the diameter of the second liquid outlet hole.

[0010] As a further embodiment of this invention, there is a gap between the first cutter and the coating roller, and the height of the gap is not higher than the height between the coating roller and the liquid separator.

[0011] As a further embodiment of this invention, the bottom of the liquid distribution rack is arc-shaped, and the center of the arc coincides with the rotation point of the coating roller.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model utilizes the combined use of a first liquid outlet, a second liquid outlet, and a first cutting tool to allow UV adhesive to flow out from the first and second liquid outlets and land on the coating roller.

[0014] 2. This utility model, by providing a height adjustment component, changes the height between the coating roller and the support roller, so that floorboards with a thickness not exceeding the moving stroke of the support frame can be placed on the support roller, thereby adapting to floorboards of different thicknesses and improving the applicability of the device.

[0015] 3. By incorporating a leveling component, the smoothing roller can perform secondary extrusion on the UV adhesive above the floor, ensuring that the adhesive is completely applied to the floor and further improving the coating quality. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1-4This utility model provides a plastic flooring coating device, including a frame 1. A partition 4 is bolted between the inner walls of both sides of the frame 1. Two symmetrical mounting brackets 5 are bolted to the top of the partition 4. A coating roller 7 is rotatably connected between the two mounting brackets 5 via bearings. A motor that drives the coating roller 7 is bolted to one side of one of the mounting brackets 5. A first mounting bracket 9 is bolted to the top of the two mounting brackets 5. A first cutter 8 is bolted to the outer wall of one side of the first mounting bracket 9. A gap exists between the first cutter 8 and the coating roller 7. A dispensing rack 14 is bolted between the inner walls of both sides of the first mounting bracket 9. The height of the gap between the first cutter 8 and the coating roller 7 is not higher than the height of the gap between the coating roller 7 and the dispensing rack 14, which can smooth the UV adhesive flowing out of the dispensing rack 14. Multiple first liquid outlet holes 15 and second liquid outlet holes 16 are provided through the bottom of the dispensing rack 14. The multiple first liquid outlet holes 15 and second liquid outlet holes 16 are staggered, and the distance between two adjacent first liquid outlet holes 15 is the same as the diameter of the second liquid outlet hole 16, which ensures that the surface of the coating roller 7 is covered with UV adhesive. Both the first outlet 15 and the second outlet 16 are threadedly fixed to the top of an external connector 10 that communicates with an external pump. Each external connector 10 is equipped with a separate electrically controlled valve to control the discharge or stop discharge of the first outlet 15 or the second outlet 16. The bottom of the dispensing rack 14 is arc-shaped, and the center of the arc coincides with the rotation point of the coating roller 7, so that the amount of UV adhesive coming out of the first outlet 15 and the second outlet 16 is the same. The bottom inner wall of the rack 1 is equipped with a height adjustment component for adjusting the floor height. Between the two fixed racks 5, there is a laying device for secondary smoothing of the UV adhesive. When using the leveling component, first place the floorboard on one side of the height adjustment component, then use the height adjustment component to adjust the height of the floorboard so that it can contact the coating roller 7. Start the external pump so that the UV adhesive can flow out from the first liquid outlet 15 and the second liquid outlet 16 and fall onto the coating roller 7. Start the motor, and the motor drives the coating roller 7 to rotate, thereby changing the position of the UV adhesive and smoothing it out by the first cutter 8. This ensures that the UV adhesive on the coating roller 7 can be completely covered, avoiding missed coating and improving the coating quality of the floorboard.

[0023] In this invention, the height adjustment component includes an electric push rod 3 fixed to the bottom of the frame 1. The piston rod of the electric push rod 3 is fixed to a support frame 2 by bolts. The top of the support frame 2 passes through a partition 4 and is slidably connected to the partition 4. Multiple support rollers 6 are rotatably connected between the two sides of the top of the support frame 2 through bearings. The multiple support rollers 6 are raised slightly from front to back, and the total height difference does not exceed 5mm. Each of the front and rear support rollers 6 is equipped with a servo motor fixed to the outer wall of one side of the support frame 2. The servo motor can drive the support rollers 6 to rotate and start the electric push rod 3. The electric push rod 3 retracts, thereby driving the support frame 2 and the support rollers 6 to move downward, thereby changing the height between the coating roller 7 and the support rollers 6. This allows flooring with a thickness not exceeding the moving stroke of the support frame 2 to be placed on the support rollers 6, thus making it suitable for flooring of different thicknesses and improving the applicability of the device.

[0024] The leveling assembly includes a smoothing roller 12 rotating between two fixed frames 5, with the bottom of the smoothing roller 12 flush with the bottom of the coating roller 7. A support roller 6, driven by a servo motor, is located directly below the smoothing roller 12. Activating the servo motor causes the support roller 6 to rotate, thereby moving the flooring on the support frame 2 and changing its position. Simultaneously, the smoothing roller 12 performs secondary extrusion on the UV adhesive above the flooring, ensuring complete coating and further improving the coating quality. The top of the fixed frame 5 is fixed with a second mounting bracket 11 by bolts. A second cutter 13 is fixed with bolts on one side of the second mounting bracket 11, and the second cutter 13 is in contact with the smoothing roller 12. During the movement of the floor, the floor will drive the smoothing roller 12 to rotate. When the smoothing roller 12 rotates, the second cutter 13 will remove the UV glue on the smoothing roller 12, keeping the surface of the smoothing roller 12 clean. This can prevent the UV glue residue on the smoothing roller 12 from accumulating on the floor and facilitate the collection of the residual UV glue.

[0025] The working principle of this utility model is as follows: In use, the flooring to be coated is placed on the front support roller 6. The electric push rod 3 is activated, causing it to retract and move the support frame 2 and support roller 6 downwards. This changes the height between the coating roller 7 and the support roller 6, ensuring that flooring with a thickness not exceeding the travel distance of the support frame 2 can be placed on the support roller 6. The servo motor is then activated, causing the support roller 6 to rotate, thus moving the flooring and changing its position. The external pump and electronically controlled valve are activated, allowing the UV adhesive to be discharged from the first outlet hole 15 and the second outlet hole 16, landing on the coating roller 7. The motor is then activated, causing the coating roller 7 to rotate, further changing the position of the UV adhesive. The first cutter 8 will then... The UV adhesive on the coating roller 7 is smoothed to ensure even coverage, preventing missed areas and improving coating quality. As the floor moves below the smoothing roller 12, the roller applies secondary pressure to the UV adhesive, ensuring complete coverage and further enhancing coating quality. As the floor continues to move, the smoothing roller 12 rotates, causing the second blade 13 to remove excess adhesive, keeping its surface clean and preventing residue buildup. This facilitates collection of any remaining UV adhesive.
