[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] A cutting device for plastic processing and recycling, such as Figures 1-4 As shown, it includes a base frame 1, a loading bin 2, a fixing block 3, a cylinder 4, a cutting blade 5, a pressure plate 6, and a filter screen 7. The loading bin 2 is connected to the upper part of the base frame 1, which facilitates the placement of plastic products of different sizes. The loading bin 2 has a built-in shaving screen at the bottom. The fixing block 3, which supports the cylinder 4, is connected to the upper left side of the base frame 1. The cylinder 4 is mounted on the fixing block 3. The extension rod of the cylinder 4 is connected to the cutting blade 5, which facilitates the cutting of flattened plastic products. The pressure plate 6 is located below the cutting blade 5, which can squeeze plastic products of different sizes. The loading bin 2 has a filter screen 7 inside, and the size of the filter screen 7 is similar to the size of the inside of the loading bin 2.

[0021] When this device is used, during the cutting of plastic products, due to the different sizes of the plastic products, the operator needs to flatten the plastic products of different sizes. The operator places the plastic products of different sizes into the loading bin 2. After the plastic products of different sizes are placed, the operator starts the cylinder 4. The telescopic rod of the cylinder 4 drives the cutting blade 5 and the pressure plate 6 to move downward along the inner wall of the loading bin 2. During the movement of the pressure plate 6, the pressure plate 6 contacts the plastic products of different sizes and flattens them, so that the plastic products of different sizes are pressed into one piece. Then the cutting blade 5 starts, contacts the flattened plastic product and cuts it, making it easier for the operator to collect the plastic products. After the plastic products are cut, the operator can close the cylinder 4, which makes it easier to flatten the plastic products of different sizes, and thus prevents the different sizes of the plastic products from affecting the cutting process.

[0022] Example 2

[0023] Based on Example 1, such as Figure 1 , Figure 3 and Figure 4As shown, it also includes a connecting block 8, a lead screw 9, a connecting plate 10, and a throttle 11. The right side of the loading barrel 2 is provided with a threaded lead screw 9, which drives the connecting plate 10 to move. The connecting plate 10 is slidably connected to the lead screw 9. The connecting plate 10 is symmetrically fixed with connecting blocks 8 at both the front and back. There are no fewer than two connecting blocks 8. The connecting blocks 8 are slidably engaged with the loading barrel 2. The upper part of the lead screw 9 is fixed with a throttle 11. When the operator rotates the throttle 11, it drives the lead screw 9 to rotate.

[0024] When it is necessary to collect the cut plastic products, the operator turns the handle 11 to drive the lead screw 9 to rotate. The lead screw 9 drives the connecting plate 10, connecting block 8, filter screen 7 and the cut plastic products to move upward along the loading bucket 2. When the filter screen 7 moves to the appropriate position, the operator releases the handle 11, which facilitates the collection of the cut plastic products and prevents the cut plastic products from accumulating too much inside the loading bucket 2, which would affect its subsequent use.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
