After the electric precision cutting saw moves backward to the bottom, it rotates 180 degrees again, and so on, so as to facilitate continuous and efficient cutting;

[0026] 3. The precision saw for processing PE boards that can be continuously cut can achieve the purpose of automatic loosening after cutting through the coordinated use of the slider, movable plate, tooth plate, gear, gear sleeve, bracket and pressure plate. After the slider slides forward or backward to the bottom, the squeeze on the movable plate will be released, the movable plate will automatically bounce down, the tooth plate will move down, and the rotation of the gear will drive the gear sleeve, bracket and pressure plate to move up, so as to facilitate the automatic loosening of the PE board.

When the tooth plates 509 move up and down, they will drive the gears 510 to rotate.

[0041] In this embodiment, Figure 1 , Figure 4 and Figure 5 As shown, the inner side of the gear 510 is meshed with a gear sleeve 511, and limiting plates 512 are symmetrically fixed on both sides of the top of the slide rail 501.

[0042] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a bracket 513 is fixed to the top of the gear sleeve 511, and a fixing frame 514 is fixed to the upper end surface of the base 1. The bracket 513 passes through the top of the fixing frame 514 and is connected to the pressing and limiting mechanism 515.

[0043] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the pressing and limiting mechanism 515 includes a sleeve 5151, and the sleeve 5151 is fixed to the outer side of the bottom of the bracket 513 by a first fastener 5152, a pressing plate 5153 is fixed to the bottom of the sleeve 5151, and two slideways 5154 are provided on the pressing plate 5153, each slideway 5154 is slidably connected with a movable plate 5155, and the movable plate 5155 is fixed to the pressing plate 5153 by a second fastener 5156, before using the device, the heights of the sleeve 5151 and the pressing plate 5153 can be adjusted as a whole, and then the first fastener 5152 can be used to press and fix the sleeve 5151, and the movable plate 5155 can slide in the slideway 5154, which is convenient for positioning according to the size of the PE board, and after adjusting the position of the movable plate 5155, the second fastener 5156 can be used to press and fix the movable plate 5155.

[0044] In this embodiment, Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the bottom of the movable plate 5155 is connected to the limiting column 5158 through the second compression spring 5157, and the limiting column 5158 and the movable plate 5155 form a telescopic structure, and two groups of limiting columns 5158 are arranged on each movable plate 5155. Before using the device, it is necessary to adjust the height of the pressure plate 5153. After the PE plate moves to the right to a suitable position, the pressure plate 5153 moves downward and presses to fix the PE plate. The limiting column 5158 in contact with the top of the PE plate will press against the PE plate, and the limiting column 5158 against the edge of the PE plate will limit the PE plate to prevent the PE plate from horizontal displacement.

[0045] The use method and advantages of the present invention: The working process of the precision saw for processing PE boards capable of continuous cutting is as follows:

After the position to be cut of the PE board is aligned with the electric precision cutting saw 506, the screw rod 503 rotates forward, the slider 504 slides forward, and the electric precision cutting saw 506 moves forward while operating, thereby automatically cutting the PE board. During the process of the slider 504 moving forward, it squeezes the movable plate 508 to move upward, and the tooth plate 509 moves upward, thereby driving the gear 510 to rotate, and the gear sleeve 511 moves downward, thereby driving the bracket 51 3 and the pressure plate 5153 move downward, a part of the limiting column 5158 is pressed against the top of the PE plate, and the other part of the limiting column 5158 limits the PE plate to prevent the PE plate from horizontal displacement. After the slider 504 moves forward to the bottom, the squeezing of the movable plate 508 will be released, and the movable plate 508 will automatically pop down, the tooth plate 509 moves down, and the gear 510 rotates to drive the gear sleeve 511, the bracket 513 and the pressure plate 5153 to move up, thereby automatically loosening the PE plate. Before the next cutting, the electric precision cutting saw 506 rotates 180 degrees to change the direction of the electric precision cutting saw 506, and then the screw rod 503 reverses, and the electric precision cutting saw 506 operates while moving backward with the slider 504. After the electric precision cutting saw 506 moves backward to the bottom, it rotates 180 degrees again, and so on, so as to achieve the effect of continuous cutting. The operation of the second conveyor belt device 4 can transport the cut PE plate to the right.
