[0069] The unloading mechanism 10 includes a first rack 101, a second support frame 102, a gear 103, a third support frame 104, a slide rail 105, a second rack 106, a fourth support frame 108 and a first loading frame 109. The fourth support frame 108 is symmetrically arranged on the left and right sides of the top rear side of the bottom plate 1. The number of the fourth support frames 108 is 4. A first loading frame 109 is arranged between the upper sides of the fourth support frames 108. A first rack 101 is arranged on the right rear part of the lower pressure plate 5. Three third support frames 104 are arranged on the right side of the inner wall of the bottom plate 1. A slide rail 105 is arranged between the upper sides of the third support frames 104.

The push block 112 is slidably disposed on the fixing rod 111 . The second spring 113 is disposed between the push block 112 and the fixing rod 111 .

[0071] When people need to make a plastic grid, first put a piece of plastic plate on the placement plate 9, then start the motor 122, the output shaft of the motor 122 drives the rotating shaft 125 to rotate through the transmission assembly 126, thereby driving the cam 127 to rotate, when the raised side of the cam 127 contacts the first lower pressing block 2, the first lower pressing block 2 is driven to move downward, thereby driving the lower pressing plate 5 and the first supporting column 6 to move downward, the first spring 7 is compressed, the lower pressing plate 5 can extrude and shape the plastic plate on the placement plate 9, and the waste will fall down, and at the same time When the first rack 101 is pushed down, the first rack 101 drives the gear 103 to rotate, and the gear 103 drives the second rack 106 to move backward, thereby driving the fixing rod 111, the push block 112 and the second spring 113 to move backward, and then manually put multiple plastic plates into the first loading frame 109. When the raised side of the cam 127 is separated from the first lower pressing block 2, the first spring 7 returns to its original state, driving the lower pressing plate 5, the first lower pressing block 2 and the first supporting column 6 to move upward and reset. At the same time, the lower pressing plate 5 drives the first lower pressing block 2 to move upward and reset. The first rack 101 is driven to move upward and reset, the first rack 101 drives the gear 103 to reverse, the gear 103 drives the second rack 106 to move forward and reset, thereby driving the fixing rod 111, the push block 112 and the second spring 113 to move forward and reset, the fixing rod 111 will push the lowermost plastic plate in the first loading frame 109 forward, when the push block 112 contacts the second to last plastic plate, the push block 112 will clamp the second to last plastic plate, the push block 112 stops moving, the fixing rod 111 continues to move forward, and the first loading frame 109 is pushed forward. The second spring 113 is compressed, and the new plastic plate will push the extruded plastic plate forward. The extruded plastic plate is taken out manually, thereby automatically completing the intermittent feeding function of the plastic plate. When the fixing rod 111 moves backward again, the second spring 113 first returns to its original state, and then drives the push block 112 to move backward, so that the push block 112 releases the second to last plastic plate, and the other plastic plates can continue to fall down. The device repeats the operation. When all the plastic plates are extruded, the motor 122 is turned off and the waste is disposed of manually.

[0072] Example 2

[0073] On the basis of Example 1, Figure 1 , Figure 2 , Figure 7 , Figure 8 and Fig. 9As shown, it also includes a clamping mechanism 13, the clamping mechanism 13 includes a second wedge block 131, a seventh support frame 132, a first fixed block 133, a third spring 134, a second support column 135 and a second fixed block 136. A second wedge block 131 is provided on the left front side of the lower pressure plate 5, a seventh support frame 132 is provided on the left front side of the top of the bottom plate 1, a first fixed block 133 is slidably provided on the upper side of the seventh support frame 132, the second wedge block 131 cooperates with the first fixed block 133, a third spring 134 is provided between the first fixed block 133 and the upper side of the seventh support frame 132, second support columns 135 are provided on the front and rear sides of the right side of the placement plate 9, and a second fixed block 136 is provided between the left sides of the second support column 135.

[0074] When the lower pressing plate 5 moves downward, it drives the second wedge block 131 to move downward. When the second wedge block 131 contacts the first fixed block 133, it drives the first fixed block 133 to move rightward. The third spring 134 is stretched, so that the first fixed block 133 and the second fixed block 136 clamp the plastic plate to prevent the plastic plate from moving. When the lower pressing plate 5 moves upward and resets, it drives the second wedge block 131 to move upward and reset. When the second wedge block 131 separates from the first fixed block 133, the first fixed block 133 moves leftward and resets under the action of the third spring 134, thereby loosening the extruded plastic plate for manual removal.

[0075] It also includes a buffer mechanism 14, which includes a rotating block 141, a support rod 142, a fourth spring 143 and a second loading frame 144. Two support rods 142 are provided on the left and right sides of the front top of the bottom plate 1, and a rotating block 141 is provided on the upper part of the support rod 142. The front rotating block 141 is slidably connected to the front support rod 142, and a fourth spring 143 is provided between the lower side of the front rotating block 141 and the front support rod 142. A second loading frame 144 is rotatably provided between the inner sides of the rotating block 141.

[0076] It also includes an opening mechanism 15, which includes a push door 151, a third fixed block 152 and a pin 153.

The third fixed block 152 is slidably provided with a pin 153, and the pin 153 cooperates with the push door 151.

[0077] When the lower pressing plate 5 is extruding the plastic sheets, the waste will fall down into the second loading frame 144, and the push door 151 will block the waste. When all the plastic sheets are extruded, the pin 153 is manually pulled forward, and then the push door 151 is pulled upward, and then the pin 153 is inserted into the slot above the third fixing block 152, so that the pin 153 is stuck in the push door 151, and then the front side of the second loading frame 144 is manually pressed downward to rotate the second loading frame 144, thereby driving the front rotating block 141 to slide downward, and the fourth fixing block 152 is manually pressed downward. The spring 143 is compressed, and the second loading frame 144 can pour out the waste, which is convenient for people to collect and process later. When all the waste is collected, the second loading frame 144 is released, and the fourth spring 143 returns to its original state, driving the front rotating block 141 to move upward and reset, thereby driving the second loading frame 144 to rotate in the opposite direction and reset. Then, the pin 153 is manually pulled forward again, so that the pin 153 releases the push door 151, and the push door 151 can fall down and reset. Finally, the pin 153 is inserted into the slot below the third fixing block 152.
