[0021] The beneficial effects of the present invention are as follows:

[0022] (1) The present invention utilizes a flip control unit provided on one side of the cutting knife, utilizes a connecting shaft in the flip control unit to be fixedly connected to the cutting knife, and cooperates with the rotating sleeve of the connecting frame so that the cutting knife can swing in the connecting frame, and utilizes the cooperation of the push rods at both ends of the tooth plate and the magnetic ring. After completing the top thickness cutting of the sponge mattress, as the cutting knife moves further, in cooperation with the fixed push block in the track assembly, the flip control unit is pushed to move under the action of resistance, and the cutting knife is driven to swing in the opposite direction, and the cutting knife is flipped from one horizontal side to the other horizontal side, so as to realize the conversion of the cutting direction. After automatic reversal, as the mounting arm moves in the opposite direction, the sponge mattress that has been re-set in thickness can be quickly cut without resetting the cutting knife to move again. Continuous cutting can be completed directly in the process of reciprocating left and right movements, thereby greatly improving the efficiency of actual sponge mattress positioning and cutting, and achieving good use effect.

[0023] (2) The present invention further utilizes the auxiliary adjustment parts distributed on the upper and lower sides of the cutting knife and cooperates with the spindle-shaped structure of the cutting knife. When the cutting knife is cutting, the rotating rollers rotating up and down rotate in the opposite direction along the cutting direction and push the cut sponge mattress to move in the opposite direction, thereby achieving the pulling and tensioning of the sponge mattress after cutting, ensuring the stability of the sponge structure in the cutting area of ​​the cutting knife, and effectively avoiding the stacking and compression of the flexible sponge in the cutting area, thereby improving the cutting accuracy of the actual sponge mattress. Through auxiliary tension cutting, the stability and reliability of the cutting quality are guaranteed, and the comprehensive cutting effect is good.

[0024] (3) The present invention realizes the control of fixed-thickness cutting when the sponge mattress moves from bottom to top by cooperating with the positioning component that moves up and down, changing the distance between the sponge mattress and the horizontal cutting knife, and cooperating with the position of the positioning component. It also realizes the positioning of the fixed-thickness cutting of the sponge mattress, thereby realizing quick positioning and adjustment control of fixed-thickness cutting, and batch cutting is simple and convenient.

[0025] (4) The present invention reuses the positioning component and cooperates with the processing component installed in the positioning component. When performing mobile cutting, the positioning component can follow the movement after positioning. On the one hand, the positioning plate is used to realize dynamic positioning along the top of the sponge mattress being cut, and continuous guiding positioning is realized during the cutting process. On the other hand, the processing component in the positioning component is cooperated to complete the rotation grinding of the top of the sponge mattress during the movement, and further trim the cross-section after cutting, and simultaneously realize the post-processing of the sponge mattress, so as to have a high comprehensive cutting efficiency.
