The cross-cutting trolley cylinder 354 is set along the length direction of the cross-cutting lifting trolley 352. The telescopic end of the cross-cutting trolley cylinder 354 is fixedly connected to the cross-cutting trolley 353. The cross-cutting trolley 353 moves along the first guide rail 356 through the telescopic extension of the cross-cutting trolley cylinder 354.

[0045] It also includes a discharge roller 36, which is located on the side of the fixed beam 341 under the pressing net away from the cross-cutting mechanism 35. One end of the discharge roller 36 is connected to a discharge motor 37. The rotation of the discharge motor 37 can drive the discharge roller 36 to rotate, thereby discharging the cut plastic net 6 from the cutting device 3.

[0046] To facilitate the discharge of the cut plastic mesh 6 from the cutting device 3, a guide roller 38 is also included. The guide roller 38 is located on the side of the discharge roller 36 away from the lower fixing beam 341 of the mesh pressing.

As one implementation, the telescopic end of the longitudinal cutting blade lifting cylinder 322 can be rotatably connected to the longitudinal cutting blade lifting connecting rod 324 by a pin; the longitudinal cutting blade holder 323 is slidably mounted on the longitudinal cutting blade holder 321, and the longitudinal cutting blade holder 323 is locked to the longitudinal cutting blade holder 321 by a locking mechanism 325. As one implementation, the locking mechanism 325 can be a set screw. The longitudinal cutter holder 323 is equipped with a longitudinal cutter 326. By sliding the longitudinal cutter holder 323 to the longitudinal cutter frame 321, the distance between two adjacent longitudinal cutter holders 323 can be adjusted as needed, thereby adjusting the spacing of the longitudinal cutters 326, and thus realizing the cutting of pieces of different widths.

[0048] The leveling device 2 includes a leveling device frame 21 and leveling heating rollers 22. The leveling heating rollers 22 are rotatably mounted on the leveling device frame 21 and are arranged parallel to the conveyor drive roller 331. Multiple leveling heating rollers 22 are arranged in a staggered manner. In one implementation, five leveling heating rollers 22 are used. The two ends of each roller are rotatably connected to the leveling device frame 21 via bearings 23. Adjacent rollers 22 are staggered, one above the other. The plastic mesh 6 passing through the five leveling heating rollers 22 forms a "W" shape when viewed from the side. Figure 2 As shown.

[0049] The heating element of the leveling device 2 can be an electric oil heater, with hot oil passing through the leveling heating roller 22 to bring its surface to the softening temperature of the plastic mesh 6. Alternatively, heating can be achieved by arranging resistance wires inside the leveling heating roller 22. The heating temperature of the leveling device can be set according to the softening temperature of different plastic meshes 6.

[0050] For example, if the surface of the plastic mesh 6 is relatively smooth, the conveyor drive roller 331 can be coated with a rubber layer to increase the friction of the conveyor.

[0051] The entire operation process is as follows: The manual operator moves the roll of raw material plastic mesh 6 to the unwinding device 1, aligning one end of the roll with the pressure plate 16 fixed on the unwinding device frame 11. Then, by starting the width adjustment motor 15, the width adjustment trolley 14 moves, aligning the pressure plate 16 on the width adjustment trolley 14 with the other end of the roll. The width adjustment trolley 14 is further moved to clamp the roll. The manual operator then threads the plastic mesh 6 through the leveling heating rollers 22 of the leveling device 2, ensuring that the plastic mesh 6, after passing through the five leveling heating rollers 22, forms a "W" shape when viewed from the side. The heat from the leveling heating roller 22 softens the plastic mesh 6, which is then flattened by the subsequent conveying mechanism 33. The raw plastic mesh 6 is manually inserted between the conveying drive roller 331 and the conveying pressure roller 332. The conveying pressing cylinder 333 is activated, causing the conveying pressure roller 332 to move downwards and press the plastic mesh 6. The conveying motor 334 rotates, driving the conveying drive roller 331 via the chain 335, thus conveying the plastic mesh 6 backwards. The position of the longitudinal cutting blade holder 321 of the longitudinal cutting mechanism 32 is adjusted according to the required mesh width. When the longitudinal cutting blade cylinder 322 actuates, it moves the longitudinal cutting blade 326 upwards until it cuts the plastic mesh 6. The mesh-supporting cylinder 5 extends, causing the mesh-supporting frame 4 to rise, forming a step with the lower fixing beam 341. Through the conveying mechanism 33 and the guiding mechanism 4, the plastic mesh 6 is fed between the lower fixing beam 341 and the upper pressing frame 342. When the desired mesh length is reached, the conveying mechanism 33 stops conveying, the mesh-supporting cylinder 5 retracts, causing the mesh-supporting frame 4 to return to its original position. Simultaneously, the pressing cylinder 344 extends, pressing the upper pressing beam 342. The mesh frame 342 moves downward to press the plastic mesh 6 tightly; the cross-cutting toothless saw 355 rotates, and at the same time the cross-cutting lifting cylinder 351 extends to lift the cross-cutting lifting trolley 352 until the cross-cutting toothless saw blade 357 cuts the plastic mesh 6; the cross-cutting traveling trolley cylinder 354 extends, causing the cross-cutting traveling trolley 353 to move laterally along the first guide rail 356; the cross-cutting toothless saw blade 357 cuts the plastic mesh 6 laterally; the discharge motor 37 rotates to rotate the discharge roller 36, conveying the plastic mesh 6 backward; the guide roller 38 guides the finished plastic mesh 6 to complete the mesh discharge.

[0052] By repeating the above actions, the plastic mesh can be fed, unwound, leveled, longitudinally cut, conveyed, pressed, transversely cut, and discharged, thus completing the plastic mesh cutting process. When the raw material plastic mesh rolls are almost used up, new material can be connected to the old material with soft wire to achieve continuous production without the need for manual feeding again.

[0053] Compared with existing manual slicing methods, this disclosure greatly liberates productivity, reduces labor intensity, and realizes automated production in the cross-cutting and longitudinal cutting processes, resulting in a significant improvement in production efficiency.
