[0037] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0038] A specific embodiment of the present application is as shown in Figures 1-3 A PVC plastic floor compaction device, comprising a support 1, one end of the support 1 is rotatably connected with a compression roller 2, one end of the support 1 close to the compression roller 2 is provided with a mounting bracket 3, the mounting bracket 3 is rotatably connected with a paste roller 4 which is closely attached to the floor, the paste roller 4 is provided with a plurality of axial clamping grooves 423 along its circumference, and a scraper assembly 5 is further installed on the mounting bracket 3 to push the impurities on the surface of the paste roller 4 into the axial clamping grooves 423. In the process of pushing the compaction device to compact the floor, the paste roller 4 rotates to paste and clean the granular impurities in front of the movement track, and then compacts the floor through the compression roller 2, which avoids the situation that the granular impurities such as sand and stone are stuck into the inside of the plastic floor, and improves the compaction efficiency and quality of the floor. At the same time, in the process of pasting the granular impurities by the paste roller 4, the scraper assembly 5 pushes the impurities on the surface of the paste roller 4 into the axial clamping grooves 423, which avoids the problem that the impurities on the surface of the paste roller 4 fall off and affect the rolling effect.

[0039] Specifically, as shown in Figure 3 and Figure 5 The mounting bracket 3 comprises a fixed bracket 31 fixedly connected with the support 1, the fixed bracket 31 is arranged as a T-shaped bracket, the fixed bracket 31 is connected with a U-shaped limiting bracket 33 through two telescopic rods I 32, the telescopic rod I 32 is an electric telescopic rod, the two ends of the U-shaped limiting bracket 33 are connected with the paste roller 4 through elastic pressing mechanisms 34, the length of the telescopic rod I 32 is controlled to make the paste roller 4 closely attached to the floor in cooperation with the elastic pressing mechanisms 34, which ensures the compaction effect.

[0040] The end of the U-shaped limiting frame 33 is provided with a strip-shaped guide slot 331 along the length direction, and the elastic pressing mechanism 34 comprises a sliding block 341 slidingly connected in the strip-shaped guide slot 331, one end of the sliding block 341 is connected with one end of the strip-shaped guide slot 331 through a compression spring 342, and the sliding block 341 is rotatably connected with the end of the sticking roller 4. Under the action of the compression spring 342, the sliding block 341 can drive the sticking roller 4 to move downward, so that the sticking roller 4 is always in close contact with the floor. Even if there are large particles on the floor, the sticking roller 4 can also successfully extrude and stick the large particles.

[0041] As shown in Figure 6 and Figure 7 , the sticking roller 4 comprises a roller shaft 41 rotatably connected with the mounting frame 3, and a buffer cylinder 42 is sleeved and positioned on the roller shaft 41. The buffer cylinder 42 can be a sponge cylinder or a rubber cylinder. A double-sided sticking layer 43 is adhered to the roller surface of the buffer cylinder 42, which is used to stick the particle impurities and can also be torn off and replaced. The buffer cylinder 42 comprises a cylinder body 421, and a plurality of axial protrusions 422 are arranged on the outer surface of the cylinder body 421 at intervals in the circumferential direction. An axial clamping groove 423 is formed between every two adjacent axial protrusions 422 at a distance. The particle impurities are stuck by the axial protrusions 422, and the particle impurities adhered are temporarily stored by the axial clamping grooves 423, thereby increasing the space for adhering the particle impurities.

[0042] The cross section of the axial protrusion 422 is T-shaped, and the axial protrusion 422 comprises a sticking section tangent to the outer surface of the cylinder body 421, and two symmetrical inclined sections are arranged on both sides of the sticking section. The sticking section is connected with the cylinder body 421 through a hollow strip, and the cross section of the hollow strip is rhombic. The particle impurities will be clamped at the position between every two adjacent axial protrusions 422 along the inclined sections, thereby improving the stability of the particle impurities clamped and adhered, and avoiding the situation that the impurities adhered on the surface of the double-sided sticking layer 43 fall off. The rhombic hollow strip increases the elastic performance of the axial protrusion 422, and further improves the clamping effect of the particle impurities.

[0043] Specifically, as shown in Figure 8 and Figure 9As shown, the U-shaped limiting frame 33 is slidably connected with a pasting assembly 6 along the length direction of the U-shaped limiting frame 33 for assisting in pasting the double-sided pasting layer 43. The pasting assembly 6 includes an L-shaped sliding plate 61 slidably connected on the U-shaped limiting frame 33, one end of the L-shaped sliding plate 61 is provided with a through hole and a threaded hole, a connecting rod 62 is slidably connected in the through hole, the lower end of the connecting rod 62 is fixedly connected with a mounting ring 64, an adjusting screw rod I 63 is threadedly connected in the threaded hole, the lower end of the adjusting screw rod I 63 is rotatably connected with the mounting ring 64; the mounting ring 64 coincides with the center axis of the pasting roller 4, and the mounting ring 64 is slidably sleeved with the pasting roller 4. When it is necessary to replace the double-sided pasting layer 43 on the buffer cylinder 42, after the used double-sided pasting layer 43 is removed from the buffer cylinder 42, the new double-sided pasting layer 43 in the form of a cylindrical structure is temporarily attached to the position on the outer surface of the buffer cylinder 42, the adjusting screw rod I 63 is rotated, the mounting ring 64 is driven to the position with the same center as the buffer cylinder 42, at this time, the mounting ring 64 is slid along the length direction of the U-shaped limiting frame 33, the mounting ring 64 is sleeved on the surface of the double-sided pasting layer 43, the double-sided pasting layer 43 is better attached to the buffer cylinder 42, and high-efficiency and high-quality installation of the double-sided pasting layer 43 is realized.

[0044] The mounting ring 64 is provided with a conical hole section 641 close to one end of the pasting roller 4, which facilitates the quick sleeving positioning between the mounting ring 64 and the buffer cylinder 42, the mounting ring 64 is provided with T-shaped grooves 642 allowing the corresponding axial protrusions 422 to pass through at intervals in the circumferential direction, which can make the double-sided pasting layer 43 tightly attached to the outside of the axial protrusions 422 of the buffer cylinder 42, a plurality of balls 643 are arranged at intervals on the inner wall of the mounting ring 64 and are rotatably connected with the axial clamping grooves 423 through the balls 643, which reduces the friction between the double-sided pasting layer 43 and the mounting ring 64, and further improves the replacement effect of the double-sided pasting layer 43 on the buffer cylinder 42.

[0045] Specifically, as Figure 4 and Figure 5As shown in the drawings, the scraper assembly 5 comprises a vertical plate 53 connected to one side of the U-shaped limiting frame 33 through telescopic rods II 51 and adjusting screws II 52. The adjusting screws II 52 are arranged at the middle of one end of the vertical plate 53, and the telescopic rods II 51 are arranged at both sides of the adjusting screws II 52. The bottom of the vertical plate 53 is fixed with an arc-shaped scraper I 54. A sliding sleeve 56 is slidably connected to the vertical plate 53, and the bottom of the sliding sleeve 56 is fixed with an arc-shaped scraper II 55. The arc-shaped scrapers I 54 and II 55 are arranged oppositely and in contact with the surface of the sticking roller 4. The arc-shaped scrapers I 54 and II 55 can be made of rubber. By rotating the adjusting screws II 52, the positions of the arc-shaped scrapers I 54 and II 55 can be adjusted. The arc-shaped scraper I 54 is located at the edge of the axial protrusions 422. During the rotation of the sticking roller 4, the arc-shaped scraper II 55 slides along the vertical plate 53 due to gravity, so that the arc-shaped scraper II 55 moves relative to the surface of the axial protrusions 422. The arc-shaped scrapers I 54 and II 55 cooperate to push the particles adhered to the axial protrusions 422 into the corresponding axial clamping grooves 423.

[0046] In addition, the sliding sleeve 56 is made of iron, and one side of the vertical plate 53 is provided with a positioning magnetic block 57 for positioning the arc-shaped scraper II 55 and separating it from the sticking roller 4. When the sliding arc-shaped scraper II 55 is attracted to the positioning magnetic block 57, the arc-shaped scraper II 55 is separated from the sticking roller 4. When there are many particles clamped in the axial clamping grooves 423, the interior needs to be cleaned. The sliding sleeve 56 is attracted to the positioning magnetic block 57, so that the arc-shaped scraper II 55 is separated from the sticking roller 4. The sticking roller 4 is reversely rotated, and one side of the arc-shaped scraper I 54 hooks and pushes one side of the axial protrusions 422, so that the particles temporarily stored in the axial clamping grooves 423 can be conveniently cleaned regularly.

[0047] Specifically, as shown in the drawings, Figure 1 and Figure 2 The support 1 comprises a U-shaped frame 11, the two ends of the U-shaped frame 11 are rotatably connected to the pressing roller 2, and the middle of the U-shaped frame 11 is connected to a push rod 12. The end of the push rod 12 is provided with a handle 13. The handle 13 is convenient for pushing the support 1 to drive the pressing roller 2 and the sticking roller 4 to rotate to realize the cleaning of the impurities and the pressing operation.

[0048] In addition, as shown in the drawings, Figure 10 and Figure 11As shown, the two ends of the U-shaped frame 11 are connected to the rotating frame 8 through the sliding adjustment mechanism 7, and the pressure cylinder 9 is rotatably connected between the two rotating frames 8. The pressure cylinder 9 is provided with a plurality of arc-shaped wings 91 arranged in a clockwise or counterclockwise direction along the circumference thereof. The outer end of the arc-shaped wing 91 is in a sharp corner structure, which is used to press the narrow gap area between the floor and the base plate. The sliding adjustment mechanism 7 includes a guide frame 71 fixed to the outer side of the U-shaped frame 11, and a sliding plate 72 slidably connected to the guide frame 71. One end of the sliding plate 72 is connected to the guide frame 71 through an adjusting screw rod III 73. Since the pressure roller 2 has a large volume and is suitable for large-area floor compaction operation, and the pressure cylinder 9 has a small volume and is suitable for narrow-area floor compaction operation, the height of the pressure cylinder 9 can be adjusted to be lower than that of the pressure roller 2 by rotating the adjusting screw rod III 73, so that the pressure roller 2 and the pressure cylinder 9 can be used separately. The outer side of the sliding plate 72 is rotatably connected to the rotating frame 8, and the compaction angle of the pressure cylinder 9 can be adjusted according to the needs, so that it is suitable for compaction operation in different narrow areas of the floor.

[0049] The method for compaction of PVC plastic floor by using the compaction device is as follows:

[0050] 1) The PVC plastic floor is pre-laid on the ground.

[0051] 2) The height of the sticking roller 4 is adjusted, so that the sticking roller 4 and the pressure roller 2 are rolled on the laid floor to press and stick the impurities on the floor, and then the floor is compacted in a large area.

[0052] Firstly, the height of the sticking roller 4 is controlled by controlling the length of the telescopic rod I 32, and the height of the pressure cylinder 9 is kept higher than that of the pressure roller 2, so that the pressure roller 2 and the sticking roller 4 are in close contact with the laid floor. Then, the push rod 12 is pushed by holding the handle 13, so that the pressure roller 2 and the sticking roller 4 move on the laid floor. The sticking roller 4 rotates to stick and clean the granular impurities in front of the movement track, and then the pressure roller 2 follows to compact, so that the granular impurities such as sand are prevented from penetrating into the plastic floor, and the arc-shaped scraper I 54 and the arc-shaped scraper II 55 cooperate to push the granular impurities adhered to the axial protrusions 422 into the corresponding axial clamping grooves 423. According to the above method, the laid floor is rolled until most of the floor is compacted, and only the joint between the floor and the wall is not compacted.

[0053] 3) The height of the pressure cylinder 9 is adjusted to be lower than that of the pressure roller 2, so that the pressure cylinder 9 rolls along the edge of the floor laid at the corner of the wall until the edge of the corner is compacted.

[0054] First, screw adjusting screw rod III 73 makes the slide plate 72 along the guide frame 71 to move down, make the pressure cylinder 9 to move down; then, adjust the angle of the rotating frame 8 and position by bolt, make the height and angle of the pressure cylinder 9 meet the construction requirement; finally, hold the handle 13, push the push rod 12, make the pressure cylinder 9 roll towards the position of the wall side or the wall corner, and roll to press the floor and the joint of the wall body.

[0055] In conclusion, the application can clean the sand and other granular impurities while rolling in the process of floor compaction, avoid the sand and other granular impurities from entering the inside of the plastic floor, and can compact the floor in different laying positions, so that the floor compaction efficiency is high and the effect is good.

[0056] The above description is only to illustrate some principles of the application, and this specification is not intended to limit the application to the specific structure and application range shown and described, so all possible corresponding modifications and equivalents belong to the patent application scope of the application.
