[0057] A reset component is provided on the second transmission rod 208;

[0058] In one embodiment, such as Figures 3-6 As shown, the reset assembly includes two connecting rotating plates 206 symmetrically fixedly connected to the outer wall of the second transmission rotating rod 208. The two connecting rotating plates 206 are located at opposite ends of the two connecting pull plates 2011. Two torsion springs 207 are symmetrically sleeved on the outer wall of the second transmission rotating rod 208. The torsion springs 207 are located between the connecting rotating plates 206 and the connecting pull plates 2011. The two ends of the torsion springs 207 are respectively formed with end heads that penetrate into the connecting rotating plates 206 and the connecting pull plates 2011. The connecting rotating plates 206 and the connecting pull plates 2011 are integrally formed with slots for inserting the end heads. Through the reset assembly, the second baffle 2010 can be flipped under the obstruction of the composite floor during the reset process of the moving slide frame 2015.

[0059] The above embodiment discloses a composite flooring pressing machine. In use, the composite flooring to be processed is placed on the upper surface of the base 4 and positioned between the first baffle 202 and the second baffle 2010. Then, the second motor 2016 is started to drive the first transmission rod 205 to rotate. At this time, the two gear rings 204, driven by the first transmission rod 205, mesh with the two racks 203 to move. Simultaneously, the moving pull plate 201, driven by one rack 203, moves multiple first baffles 202 along the moving slide. The inner walls of the frame 2015 and the base 4 slide. At this time, the connecting pull plate 2011, driven by another rack 203, drives multiple second baffles 2010 to move through the second transmission rod 208 and the limit stop rod 209. When the first baffle 202 contacts the outer wall of one end of the composite floor, the composite floor moves along the upper surface of the base 4 under the push of the first baffle 202 until the outer wall of the other end of the composite floor contacts the outer wall of the second baffle 2010. This allows for convenient positioning and centering of composite flooring of different specifications.

[0060] Then, the first motor 2012 is started to drive the lead screw 2014 to rotate. At this time, the movable push plate 2013, driven by the thread of the lead screw 2014, pushes the movable slide frame 2015 to slide along the inner wall of the base 4. At the same time, the composite flooring enters the inner cavity of the press body 1 through the feed port 3 through the first baffle 202 driven by the movable slide frame 2015, until the movable slide frame 2015 contacts the inner wall of one end of the base 4, so that the composite flooring can be pushed conveniently.

[0061] At this time, the second electric push rod 9 is activated to push the positioning block 10 and the pressing plate 11 to separate from each other. Simultaneously, the positioning block 10 presses the upper surface of the composite flooring and positions it. Then, the second motor 2016 is activated to drive the first transmission rod 205 to rotate, thereby restoring the distance between the first baffle 202 and the second baffle 2010 and separating them from the outer wall of the composite flooring. Then, the first motor 2012 is activated to drive the lead screw 2014 to rotate in the opposite direction, thereby moving the sliding frame 2015 to its original position. During this process, when the second baffle 2010 contacts the outer wall of the composite flooring, the second baffle 2010... When the composite floor is blocked, the second transmission rod 208 rotates around the axis. At this time, the second baffle 2010 slides along the outer wall of the limiting rod 209 through the arc-shaped groove. At the same time, the second transmission rod 208 rotates along the inner wall of the connecting plate 2011 under the drive of the second baffle 2010, and drives the two connecting plates 206 to rotate synchronously. At this time, the connecting plates 206 twist the torsion spring 207 by rotating until the second baffle 2010 separates from the composite floor. At this time, the torsion spring 207 can drive the connecting plates 206 to rotate and reset by the torsion rebound, so that the second baffle 2010 can reset along the outer wall of the limiting rod 209.

[0062] Then, the first electric push rod 5 is activated to push the lifting pusher 7 down along the inner wall of the press body 1 and the support plate 8. At this time, the pressing plate 11 is pushed by the lifting pusher 7 to squeeze the upper surface of the composite flooring, thereby extruding and processing the composite flooring. During this process, the next composite flooring can be placed on the upper surface of the base 4. After one composite flooring is processed, the above operation is repeated to push the next composite flooring into the inner cavity of the press body 1 and push the processed composite flooring to the other end of the press body 1. This achieves the purpose of convenient loading and unloading of composite flooring, thereby further improving the processing efficiency of composite flooring of different specifications.
