The top ends of both are fixedly connected with pressing plates 25 respectively, and the bottom ends are respectively installed and fixed to the feeding structure 3 and the stepping structure 4; A pair of tension springs 27 are respectively sleeved on a pair of lifting rods 26, and the two ends of the tension spring 27 are respectively connected and fixed to the bottom of the mounting plate 22 and the top of the feeding structure 3 or the stepping structure 4;

[0043] The pressing rod 24 has a bifurcated structure, and the two bifurcations are respectively rotatably installed and connected with a pair of pressing wheels 25; The pressing-down motor 23 is installed on the mounting plate 22, and its output end is fixedly installed with the pressing rod 24, driving the pressing rod 24 to drive a pair of pressing wheels 25 to swing, so that any one of the pair of pressing wheels 25 presses down on the corresponding pressing plate 25 from above in the form of rolling contact, and the other pressing wheel 25 is separated from the corresponding pressing plate 25.

[0044] Preferably, the feeding structure 3 includes a feeding frame 31, a feeding motor 32, a feeding rotating shaft 33 and each feeding wheel 34;

[0045] The feeding motor 32 is installed on the feeding frame 31, and its output end is axially connected to the feeding rotating shaft 33 rotatably installed on the feeding frame 31, and each feeding wheel 34 is installed and fixed to the feeding rotating shaft 33;

Each feeding wheel 34, as the output end of the feeding structure 3, presses on the top of the building insulation board in the form of rolling contact, driving the building insulation board to perform a feeding movement.

[0048] Preferably, the stepping structure 4 includes a stepping frame 41, a stepping motor 42, each driving wheel 43, each steering wheel 44, each stepping wheel 45;

[0049] Each stepping wheel 45 is rotatably installed on the stepping frame 41.

[0050] Each driving wheel 43 is respectively coaxially installed and fixed with each stepping wheel 45. Each driving wheel 43 and each steering wheel 44 are arranged in staggered rows and are meshed in sequence; The stepping motor 42 is installed on the stepping frame 41, and its output end is coaxially installed and fixed with any one of the driving wheel 43, the steering wheel 44 or the stepping wheel 45;

[0052] Preferably, the adjusting structures 2 are arranged in pairs at both ends of the feeding structure 3 and the stepping structure 4.

[0053] To improve the symmetry of the structure and the uniformity of the overall force distribution of the device.

[0054] Preferably, a plurality of ball bearings 13 installed for universal rotation are densely arranged in an array on the tabletop 11.

[0055] The arrangement of the ball bearings 13 converts the sliding friction between the building insulation board and the tabletop 11 into rolling friction, reducing the force required for the feeding action and the stepping action during the cutting process of the building insulation board. At the same time, it improves the smoothness and fluency of the movement of the building insulation board, and eliminates or reduces the wear of the building insulation board caused by the friction between the building insulation board and the tabletop 11.

[0056] When using the above-mentioned building insulation board cutting device to cut a block-shaped building insulation board into multiple strip-shaped building insulation boards, the feeding structure 3 and the stepping structure 4 always work alternately. Specifically, during the cutting process of each strip-shaped insulation board, the feeding structure 3 drives the building insulation board to perform a linear feeding action along the cutting direction of the cutting knife 12. After a single strip-shaped building insulation board is cut, the stepping structure 4 drives the block-shaped insulation board to perform a stepping action perpendicular to the cutting direction. Subsequently, the feeding structure 3 drives the building insulation board to perform a linear feeding action along the cutting direction of the cutting knife 12 to cut the next strip-shaped building insulation board.

[0057] When the feeding structure 3 works, the feeding motor 32 is started to drive the feeding rotating shaft 33 to rotate, and then drives the feeding wheels 34 fixedly connected to the feeding rotating shaft 33 to rotate synchronously. Each feeding wheel 34 presses against the top of the block-shaped building insulation board and transmits the power to the building insulation board in the form of rolling friction, so that the building insulation board performs a feeding movement.

[0058] When the stepping structure 4 works, the stepping motor 42 is started to drive the driving wheel 43, the steering wheel 44 or the stepping wheel 45 connected to its output end to rotate. Since the driving wheels 43 and the steering wheels 44 are arranged alternately and meshed in sequence, and at the same time the stepping wheels 45 and the driving wheels 43 are coaxially installed and fixed in one-to-one correspondence, all the driving wheels 43, the steering wheels 44 and the stepping wheels 45 rotate synchronously under the drive of the stepping motor 42; among them, the driving wheels 43 and the stepping wheels 45 rotate in the same direction, and the steering wheels 44 rotate in the opposite direction to the driving wheels 43 and the stepping wheels 45. Each stepping wheel 45 presses against the top of the block-shaped building insulation board and transmits the power to the building insulation board in the form of rolling friction, so that the building insulation board performs a stepping movement.

[0059] The alternating work of the feeding structure 3 and the stepping structure 4 is controlled and realized by the adjusting structure 2. The specific method is as follows:

[0060] When the feeding structure 3 needs to work, the pressing motor 23 drives the pressing rod 24 to swing, causing the pressing wheel 25 above the feeding structure 3 to swing downward, pressing the corresponding pressing plate 28 downward, driving the lifting rod 26 and the feeding structure 3 installed at the bottom end of the lifting rod 26 to descend until each feeding wheel 34 presses tightly against the top of the block-shaped building insulation board; during this process, the tension spring 27 corresponding to the feeding structure 3 is stretched. When the pressure applied by the corresponding pressing wheel 25 to the pressing plate 28 is released, the pressing plate 28, the lifting rod 26, and the feeding structure 3 installed at the bottom end of the lifting rod 26 will rise and reset under the action of the elastic force of the tension spring 27, causing each feeding wheel 34 to disengage from the block-shaped insulation board.

[0061] When the stepping structure 4 needs to work, change the rotation direction of the output rotation of the pressing motor 23 and control it in the same way.
