By means of the chamfer on the inner side of each side pressing ring 31, the film on the edge of the floor can be effectively pressed when the pressing roller is pressing the film, so as to improve the fitting effect and quality of the edge film.

[0024] Specifically, the top block 33 penetrates through the outer circumference of the mounting frame 32, the number of the top blocks 33 is three, and the three top blocks 33 are arranged in a circumferential array with the center of the mounting frame 32 as the reference, and the upper end of each top block 33 is arranged in an arc shape on both sides.

[0025] In the embodiment, the position of the clamping plate 34 can be locked in the locking state by the top block 33 in cooperation with the locking ring 35, so that the clamping plate 34 can maintain a stable clamping state.

[0026] Specifically, the clamping plate 34 is arranged in an arc shape and is located inside the mounting frame 32. By means of the clamping plate 34 in the locking state, the position of the side pressing ring 31 can be locked in cooperation with the mounting frame 32 and the top block 33, so as to ensure the stability of the side pressing ring 31 in actual use, and the position of the side pressing ring 31 can be adjusted according to the actual width of the floor.

[0027] In the embodiment, the inner wall of the mounting frame 32 is provided with a reset device 4, the reset device 4 comprises a fixed plate 41 fixedly connected with the inner wall of the mounting frame 32, the side surface of the top block 33 is provided with a receiving cavity 42, the fixed plate 41 is slidably connected with the inner wall of the receiving cavity 42, the upper surface of the fixed plate 41 is fixedly connected with a spring 43, and the upper end of the spring 43 is fixedly connected with the inner wall of the receiving cavity 42.

[0028] In the embodiment, the elasticity of the spring 43 can push the top block 33 away from the roller body 2 after the top block 33 is unlocked, so that the top block 33 drives the clamping plate 34 to move away from the roller body 2.

[0029] Specific, the inner wall of the receiving cavity 42 is fixedly connected with a guide column 44, the fixed plate 41 is in sliding connection with the surface of the guide column 44, and the spring 43 is sleeved on the surface of the guide column 44. The deformation direction of the spring 43 can be guided by the guide column 44, so that the spring 43 always moves in the same direction during deformation.

[0030] Specific, the number of fixed plates 41 is two, and the two fixed plates 41 are arranged in axial symmetry with the vertical axis of the top block 33 as the axis of symmetry, and the number of springs 43 matches the number of fixed plates 41.

[0031] In this embodiment: the lower end of the spring 43 can be supported by the fixed plate 41, so that the spring 43 pushes the top block 33 upward when the force is lost.

[0032] Working principle: when the compression roller is used for processing, the compression roller is installed on the specified position of the laminating machine, the laminating machine is an existing known floor laminating equipment, and the working principle and the installation steps of the compression roller will not be described here. After completing the installation, turn on the switch of the laminating equipment, the laminating equipment drives the compression roller to rotate, and the compression roller is pressed on the surface of the bamboo floor in cooperation with the laminating equipment during rotation;

[0033] When the compression roller is working, the side pressing ring 31 located on both sides of the compression roller will use the inclined surface of the side pressing ring 31 to assist the compression roller to press the film on the edge of the floor, so as to increase the pressing effect of the film on the edge of the floor;

[0034] When the width specification of the floor changes, the fastening bolt 37 is unscrewed, the fastening bolt 37 is separated from the slot 38 and loses the locking of the locking ring 35, the locking ring 35 is rotated, the recessed part of the sliding groove 36 in the locking ring 35 is close to the top block 33, when the top block 33 is completely overlapped with the recessed part of the sliding groove 36, the top block 33 loses the pressing effect of the locking ring 35, and at the same time, the top block 33 loses the pressure applied by the spring 43. The spring 43 loses the pressure and rebounds, and pushes the top block 33, the top block 33 pulls the clamping plate 34 away from the roller body 2 under the action of the spring 43, and then the mounting frame 32 loses the locking effect on the side pressing ring 31. When the side pressing ring 31 loses the locking, the distance between the two side pressing rings 31 is adjusted according to the width of the floor;

[0035] After the spacing between the side pressure rings 31 is adapted to the floor width, the locking ring 35 is turned in the opposite direction in the above step, the locking ring 35 is pressed against the top block 33 under the action of the sliding groove 36, the top block 33 is forced to push the clamping plate 34 and press the spring 43, the spring 43 is deformed under the action, at the same time, the clamping plate 34 is pushed to re-resist to the surface of the roller body 2, when the locking ring 35 is turned to the maximum rotation angle, the fastening bolt 37 overlaps with the insertion slot 38, the fastening bolt 37 is tightened, the fastening bolt 37 is re-inserted into the insertion slot 38, and the position of the locking ring 35 is locked, then the locking ring 35 can cooperate with the top block 33, the clamping plate 34 and the mounting frame 32 to lock the position of the side pressure ring 31 after the position is adjusted, through the setting of the auxiliary device 3 and the reset device 4, the pressure roller can utilize the adjustable side pressure structure to assist in pressing the film on the edge of the floor, so as to improve the adhesion of the film on the edge of the floor, reduce the poor pressing effect of the edge film by the pressure roller, and easily lead to the problem of edge film buckling, and further improve the pressing effect of the pressure roller on the side film of the floor edge.
