When the third bevel gear 44 rotates, the reciprocating screw 441 is driven to rotate, the reciprocating screw 441 drives the connecting rod 33 to move, the connecting rod 33 drives the sliding block 32 to move, and the sliding block 32 drives the spraying pipe 15 and the scraping plate 321 to move, so that the functions of spraying the adhesive and leveling the leather layer 17 and the flame retardant layer 18 in the housing 1 of the embodiment are realized. Taking the attached drawing housing 1 as an example, when the connecting rod 33 moves to the leftmost end, the connecting rod 33 triggers the first reset switch 13, the first reset switch 13 controls the hydraulic component 21 to work through an external processor device, at this time, the hydraulic component 21 works to press the sofa leather on the second press plate 23, when the second press plate 23 is pressed, the stress is reduced, the connecting column 24 is also reduced and drives the motor 45 to be reduced, at this time, the first rotating disc 431 and the second rotating disc 451 are separated, and the third bevel gear 44 loses power and does not rotate any more. When the hydraulic component 21 finishes pressing, the first pressing plate 22 resets, the connecting column 24 resets, at this time, the first rotary plate 431 and the second rotary plate 451 are attached again, the third bevel gear 44 obtains power again, the traction device 4 also continues to pull the sofa leather to move, when the connecting rod 33 moves to the second reset switch 131, the first reset switch 13 controls the motor 45 to rotate reversely through an external processor device, and when the motor 45 rotates reversely, the traction device 4 and 5 in combination with the table and the drawings can know that the first bevel gear 423 cannot drive the second rotary shaft 421 to rotate, that is, the traction device 4 cannot pull the sofa leather to move any more, and at this time, the first traction roller 41 and the second traction roller 42 play a role in fixing the horizontal direction of the sofa leather, because the first traction roller 41 cannot rotate clockwise in the direction shown in fig. 6, that the second traction roller 42 cannot rotate in the counterclockwise direction, that the sofa leather cannot move leftward, and it is easy to know that the traction force generated when the scraping plate 321 performs leveling in pressing of the pressing device 2 or pressing. When the connecting rod 33 moves to the first reset switch 13 again, the first reset switch 13 controls the motor 45 to switch the direction again through the external processor device, at this time, when the pressing action is finished, the traction device 4 drives the connecting rod 33 and the sofa leather to move to the rightmost end, the connecting rod 33 triggers the second reset switch 131 again, so as to reciprocate, wherein the external processor device controls the motor 45 and the hydraulic component 21 by following the algorithm steps, the hydraulic component 21 can be triggered by the first reset switch 13 once, but the motor 45 can be controlled to rotate once when the signal of the first reset switch 13 is received twice, the motor 45 can be triggered by the second reset switch 131 once, and the complete working process of one time is that the external processor device receives the signal from the first reset switch 13 twice and the signal from the second reset switch 131 once.
The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the above embodiments, and any variations that can be made by those skilled in the art are intended to fall within the scope of the present invention.
