A hydraulic cylinder is embedded in the top of the fixed seat 17, and the output end of the hydraulic cylinder is fixedly connected to the L-shaped frame 18. A T-shaped slider 20 is fixedly installed on the side of the base 16 near the workbench 1. The T-shaped slider 20 is inserted into the interior of the workbench 1 and slidably connected to it. A second servo motor 19 is fixedly installed inside the workbench 1. A second threaded rod is fixedly installed at the output end of the second servo motor 19, and the second threaded rod is rotatably connected to the workbench 1. The second threaded rod passes through the T-shaped slider 20 and is threadedly connected to it.

[0039] The top of the fixing seat 17 is provided with multiple fixing bolts, and the multiple fixing bolts all pass through the fixing seat 17 and are threaded to it. The multiple fixing bolts are all inserted into the interior of the base 16 and are threaded to it.

[0040] L-shaped limiting plates are fixedly installed on both sides of the fixed base 17. Both L-shaped limiting plates are inserted into the interior of the L-shaped frame 18 and slidably connected to it. Multiple protrusions are fixedly installed on one side of the fixed plate 3, and multiple sliding grooves that cooperate with the protrusions are opened on one side of the fixed plate 3.

[0041] A third servo motor 21 is fixedly installed inside the L-shaped frame 18. A third threaded rod 22 is fixedly installed at the output end of the third servo motor 21.

[0043] In this embodiment of the utility model, when it is necessary to replace the fixing plate 3 of different specifications to adapt to the processing requirements of polypropylene sheets of different sizes and shapes, the operator can quickly embed the fixing plate 3 with the corresponding protrusion into the groove of another fixing plate 3. Through the precise engagement of the protrusion and the groove, the fixing plates 3 can be quickly positioned and spliced. At the same time, the insert block 4 at the bottom of the fixing plate 3 cooperates with the auxiliary groove on the base 2 to further securely install the spliced ​​fixing plate 3 group on the base 2. This structure avoids the cumbersome alignment and fixing operations in the traditional connection method, greatly shortens the equipment debugging time, improves the production preparation efficiency, and enables the equipment to quickly adapt to diverse processing tasks.

[0044] The first servo motor 12 in the connection structure drives the worm gear 13 to rotate, which in turn drives the first threaded rod 10 to rotate through the worm wheel 11. This causes the insert plate 9, which is threadedly connected to the first threaded rod 10, to slide on the base 2. This allows two corresponding insert plates 9 to be inserted into the insert block 4, connecting the insert block 4 to the base 2 and connecting multiple fixed plates 3. When processing large plates, multiple fixed plates 3 can be spliced ​​together to expand the bearing area. The position of the base 2 can be precisely adjusted through the connection structure, allowing the cutting blade 24 to cover the entire processing area. Furthermore, since the fixed plates 3 adopt a combination connection method of protrusions, insert plates 9, and insert blocks 4, when a fixed plate 3 is damaged and needs replacement, it can be quickly disassembled and replaced.

[0045] The second servo motor 19 starts, driving the second threaded rod to rotate. This drives the base 16 to slide on one side of the worktable 1 via the T-shaped slider 20, adjusting the lateral position of the cutting mechanism. Simultaneously, the hydraulic cylinder extends and retracts to adjust the height of the L-shaped frame 18. The third servo motor 21 drives the third threaded rod 22 to rotate, further precisely adjusting the position of the cutting blade 24 to adapt to different cutting requirements. At the same time, the fourth servo motor 25 drives the second cross-shaped ring 27 to rotate via the drive gear 26, realizing the cutting operation of the cutting blade 24 on the polypropylene sheet to adapt to different cutting requirements.

[0046] The fixed base 17 is bolted to the base 16 by multiple fixing bolts. When the equipment is maintained, parts are replaced, or the position of the fixed base 17 is adjusted according to different processing requirements, the fixed base 17 can be quickly disassembled and reinstalled by loosening the bolts, which improves the flexibility and maintainability of the equipment.

[0047] The controller 28 enables centralized control of all electric components. Operators only need to set the corresponding parameters on the controller 28 to complete operations such as fixing, adjusting, rotating and cutting the sheet metal. The operation is simple and convenient, reducing the labor intensity and skill requirements of operators and improving production efficiency.

[0048] Example 3: Please refer to the appendix of the instruction manual. Figure 4-6 In a preferred embodiment of the present invention, protrusions are fixedly installed on both sides of the second cross-shaped ring 27. Both protrusions are inserted into the interior of the cutting blade 24 and slidably connected thereto. A fixing bolt is provided on the side of the cutting blade 24 away from the L-shaped frame 18. A partition is fixedly installed on the outside of the fixing bolt. The fixing bolt is inserted into the interior of the second cross-shaped ring 27 and threadedly connected thereto. The partition is slidably connected to the cutting blade 24.

[0049] A door is provided on one side of the mounting base 23. The door is inserted into the interior of the mounting base 23 and slidably connected to it. Multiple fixing bolts are provided on the side of the door away from the mounting base 23. The multiple fixing bolts are inserted into the interior of the L-shaped frame 18 and threadedly connected to it. The multiple fixing bolts pass through the door and are threadedly connected to it. A dust suction pipe is fixedly installed at the bottom of the mounting base 23. Multiple dust suction pipes are inserted into the interior of the mounting base 23 and connected to it. An air suction pump is embedded on the side of the door away from the mounting base 23, and the air intake pipe of the air suction pump is connected to the mounting base 23. A filter plate is provided inside the air intake pipe of the air suction pump.

[0050] L-shaped side plates are fixedly installed on both sides of the fixed plate 3. Two L-shaped mounting plates are slidably connected to the top of the L-shaped side plates. A second electric telescopic rod is embedded in the top of each of the two L-shaped mounting plates. A pressure plate is fixedly installed at the output end of each of the two second electric telescopic rods. Fixing bolts are provided on the opposite sides of the two L-shaped mounting plates, and the fixing bolts pass through the L-shaped mounting plates and are threaded to them. Insert holes for the fixing bolts are provided on each of the two L-shaped side plates. The controller 28 is electrically connected to the second electric telescopic rod.

[0051] In this embodiment of the invention, the cutting blade 24 is connected to the second cross-shaped ring 27 by a fixing bolt. The partition plate and the cutting blade 24 are in sliding engagement. When the blade needs to be replaced, the operator only needs to unscrew the fixing bolt to separate the cutting blade 24 from the second cross-shaped ring 27, achieving quick disassembly. Simultaneously, during installation, the sliding groove on the cutting blade 24 is aligned with the protrusion of the second cross-shaped ring 27 and inserted, and then the fixing bolt is tightened to secure the partition plate, thus completing the installation of the new blade. This structure significantly shortens the blade replacement time, reduces equipment downtime, and improves production efficiency.

[0052] During the cutting process of polypropylene sheet, the cutting blade 24 cuts the sheet. The dust suction pipe at the bottom of the mounting base 23, together with the air suction pump, sucks the cutting debris and dust into the mounting base 23. After being filtered by the filter plate, the dust is discharged, keeping the working environment clean and preventing debris from affecting the cutting accuracy and equipment operation.

[0053] The second electric telescopic rod is controlled by controller 28, which can precisely adjust the downward pressure of the pressure plate. After the polypropylene sheet is placed, the operator starts the second electric telescopic rod through controller 28. Its output end drives the pressure plate to press down quickly, firmly pressing the sheet onto the fixed plate 3. The L-shaped mounting plate slides on the top of the L-shaped side plate and is fixed by fixing bolts and the insertion holes on the L-shaped side plate. This design allows the position of the L-shaped mounting plate to be flexibly adjusted according to the size of the sheet.

[0054] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
