Description

Technical Field

[0001] The invention relates to the field of cutting technology, in particular to a PMI foam cutting device with self-cleaning capability. Background Art

[0002] In the processing of PMI foam, trimming and peeling the entire rough sheet before processing it into the specified dimensions is a critical step. Currently, the industry generally uses saw blade cutting for the initial cutting of PMI foam. However, this process has significant drawbacks. The intense friction between the saw blade and the PMI foam surface during sawing can easily damage the surface structure of the PMI foam. PMI foam has a unique closed-cell structure. Once the surface layer is damaged, the internal cells will rupture, forming a large amount of fine powder. This powder adheres to the foam surface, requiring additional cleaning work before shipment, increasing processing steps and time costs, and seriously restricting production efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-Figure 7 As shown, an embodiment of the present invention provides a PMI foam cutting device with self-cleaning capability, including a cutting support table 100. The cutting support table 100 is a U-shaped structure. A mounting slot is provided in the middle of the upper end of the cutting support table 100. A conveyor belt group 200 for conveying the foam block A is provided in the mounting slot. The conveyor belt group 200 drives the foam block A to be horizontally transferred to achieve continuous cutting. A fine-adjustment bracket 302 is provided above the conveyor belt group 200. The fine-adjustment bracket 302 is provided with a cutting assembly for cutting the foam block A. The fine-adjustment bracket 302 is connected to a height adjustment assembly for adjusting its height. The height adjustment assembly is used to adjust the cutting thickness. The fine-adjustment bracket 302 is provided with a dust collection assembly for sucking away debris generated by cutting.

[0034] The dust collection component includes two guide side frames 308 for guiding the cutting position of the foam block A. The two guide side frames 308 are connected to the distance adjustment component, and the distance adjustment component is used to match the width of the foam block A. The ends of the guide side frames 308 are provided with guide bevels 312 for guiding the foam block A. The guide side frames 308 are provided with a dust collection port 310 for facilitating the passage of the cutting line. The ends of the guide side frames 308 are provided with a plurality of guide wheels 309 for guiding the sides of the foam block A. The guide side frames 308 are provided with a dust collection port 310 for facilitating the passage of the cutting line. The dust collection hose 301 is connected to the dust collection hose 301 310, and the other end of the dust collection hose 301 is connected to the dust collection end of the first dust collection fan 300. In this way, when the conveyor belt assembly 200 drives the foam block A to transfer, the foam block A will be guided to a flat state under the guidance of the guide bevel 312. Under the limit of the guide wheel 309, it will not be affected by the lateral force generated by cutting. The debris generated by cutting will be sucked away along the dust collection port 310 and the dust collection hose 301, thereby reducing the dust pollution generated by cutting. The exhaust end of the first dust collection fan 300 is connected to the filter box to collect dust.

[0035] The distance adjustment assembly includes a suspension rod 306 connected to a guide side frame 308. The upper end of the suspension rod 306 is connected to an auxiliary slider 304.

The height of the pressing roller 603 is adjusted by the lifting pushing rod 601, so that the pressing roller 603 can press A on the surface of the conveyor belt group 200, so that it will not jump due to cutting.

[0038] The height adjustment component includes a floating screw sleeve 503 fixedly arranged at the upper end of the fine-tuning bracket 302, and a floating screw 501 is threaded on the upper end of the floating screw sleeve 503. The upper end of the floating screw 501 is connected to the output end of the floating motor 502. A floating frame 500 is provided above the fine-tuning bracket 302, and the floating motor 502 is installed at the bottom of the floating frame 500. Floating slide bars 504 are symmetrically provided at both ends of the floating frame 500.

The bottom of the floating slide bar 504 is fixedly connected to the horizontal sliding frame 505. Under the drive of the floating motor 502, the floating screw 501 and the floating screw sleeve 503 rotate relative to each other. Under the action of the thread, the floating screw sleeve 503 will drive the fine-tuning bracket 302 to slide up and down along the floating slide bar 504, thereby providing power for height adjustment;

[0039] The horizontal sliding frame 505 is connected to a horizontal pushing assembly for driving its horizontal movement, so that the cutting position can be adjusted to facilitate subsequent cleaning operations. The horizontal pushing assembly includes a sliding cavity 507 arranged at the lower end of the cutting support table 100, and the horizontal sliding frame 505 is slidably arranged with the sliding cavity 507. Two horizontal guide rails 506 are symmetrically provided on the cutting support table 100 where the sliding cavity 507 is located. The horizontal guide rails 506 slide through the horizontal through-holes on the horizontal sliding frame 505. A horizontal moving screw 508 is also threadedly provided at the center position of the horizontal sliding frame 505. One end of the horizontal moving screw 508 is rotatably connected to the cutting support table 100, and the other end of the horizontal moving screw 508 is fixedly connected to the output end of the horizontal motor. Under the action of the horizontal motor, the horizontal sliding frame 505 can slide along the horizontal guide rail 506, so that the floating slide bar 504 and the floating frame 500 can be driven to move horizontally;

[0040] The cutting assembly includes four cutting wheels 313 symmetrically arranged on the inner side of the fine-tuning bracket 302. The cutting wheels 313 are rotatably arranged on the fixed blocks on the surface of the fine-tuning bracket 302. One of the fixed blocks is connected to a guide bevel 312 for driving its rotation. A cutting wire 311 for cutting is arranged between the multiple guide bevel blocks 312. Under the drive of the guide bevel blocks 312, one of the cutting wheels 313 rotates and cooperates with the transmission of the other cutting wheels 313, so that the cutting wire 311 rotates at high speed to cut the foam block A.

[0041] Working principle: In actual use, the foam block A is transferred by the conveyor belt group 200, and the cutting height of the cutting assembly is adjusted according to the required cutting height. When the conveyor belt group 200 drives the foam block A to transfer, the foam block A will be guided to a flat state under the guidance of the guide bevel 312. Under the limit of the guide wheel 309, it will not be affected by the lateral force generated by the cutting. The debris generated by the cutting will be sucked away along the dust suction port 310 and the dust suction hose 301, thereby reducing the dust pollution generated by the cutting. The exhaust end of the first dust suction fan 300 here is connected to the filter box to collect the dust;

[0042] The material blocking plate 404 is driven down to the existing height by the material blocking telescopic rod 403, and the cut foam layer will be blocked by the material blocking plate 404, so that the waste layer is separated, and the exposed debris will be sucked away, completing the secondary dust removal operation. In this way, the processed debris is neat, and the dust collection on both sides can remove the debris on the surface of the cut foam block A, reducing the pollution of the cutting to the working environment.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
