[0002] Plastics are polymers made from monomers through addition or condensation polymerization. They have moderate resistance to deformation, falling between fibers and rubber. Cutting machines are classified into metal cutting machines and non-metal cutting machines based on the material they cut.

However, this manual operation process is cumbersome, inefficient, and time-consuming, making it difficult to quickly cut large quantities of plastic raw materials. Furthermore, the high dependence on manual labor leads to high labor costs, and manual operation is prone to errors and inconsistencies, resulting in poor product quality stability.

[0057] IV. Hybrid Cooling System

[0058] 1. Air-water mixed spray

[0059] Structural components: one of the following: air-water mixing nozzle, compressed air source, water pump, water tank, etc.

[0060] The top of the moving stage 26 is connected to a speed regulating valve 25 on one side of the PLC control box 3. The speed regulating valve 25 can adjust the working speed of the cylinders A20, B8 and C19 to adapt to the cutting requirements of different plastic materials and ensure cutting accuracy and quality.

[0061] The bottom of the bracket 27 is connected to a caster wheel 18, which can move the bracket 27 to different positions. Alternatively, a positioning rod can be inserted into the ground to fix the bracket 27.

[0062] In this utility model, the control of electrical components such as hydraulic cylinders A20, B8, and C19, and motor 12 can be automatic, such as PLC system control or microcontroller control, or it can be manually opened and closed by connecting switches to the control panel. The choice can be made flexibly according to the actual use situation, which will not be described in detail here.

[0063] Specifically, in use, the plastic material to be cut is passed through the space between the two sets of baffles 11, and then through the concave frame 16, the moving frame 13 and the concave frame 7 in sequence before being placed on the material tray 4. The guide rails 2 on both sides of the top of the bracket 27 provide sliding for the guide block 24. The guide block 24 drives the moving stage 26 to move along the guide rail 2. When the moving stage 26 moves to the vicinity of the positioning frame 6, the sensor 5 on the side of the positioning frame 6 starts to work. The sensor 5 can sense the position of the plastic material. Once the material is detected to have reached the predetermined position, the sensor 5 will send a signal.

[0064] After receiving the signal from sensor 5, PLC control box 3 starts working. First, it controls the hydraulic cylinders C19 on the two sets of baffles 11 located on the side of the concave frame 16 to start working. The output end of hydraulic cylinder C19 pushes the clamping plate 23 to slide on the surface of the light rod 22. The two sets of clamping plates 23 move closer to each other and clamp the plastic material from the side to ensure that the material is in a stable state during cutting. At the same time, it controls the clamping mechanism to move. The hydraulic cylinder B8 at the top of the concave frame 7 starts. The output end of hydraulic cylinder B8 drives the pressure plate 10 to move down. During the descent of the pressure plate 10, the limit rod 9 connected to its top slides down along the reserved hole on the concave frame 7. This design can ensure that the pressure plate 10 moves vertically downward and accurately clamps the plastic material on the material tray 4 to prevent the material from shifting during the cutting process.

[0065] After the raw material is clamped, the cutting mechanism starts working. The hydraulic cylinder A20 at the bottom of the connecting block 21 is activated, pushing the connecting block 21 and thus moving the moving frame 13 along the track 17. The motor 12 on the side of the moving frame 13 is activated, driving the cutting blade inside the cutting table 14 to rotate at high speed. As the moving frame 13 moves, the cutting table 14 gradually approaches the plastic raw material. The high-speed rotating cutting blade cuts the plastic into the required size. During the cutting process, the speed regulating valve 25 can adjust the working speed of the hydraulic cylinders A20, B8 and C19 to adapt to the cutting requirements of different plastic raw materials and ensure cutting accuracy and quality.

[0066] The casters 18 connected to the bottom of the bracket 27 facilitate the overall movement of the equipment. The bracket 27 can also be fixed by inserting a positioning rod into the ground. After cutting, the clamping mechanism is released, and the moving table 26 can move along the guide rail 2 to a suitable position to remove the cut plastic product (i.e., manually remove the plastic product). After the sensor 5 detects the movement, the PLC control box 3 controls the moving table 26 to return to the initial position (i.e., return to the origin) and then proceed to the next round of loading and cutting operations.

[0067] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can 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.
