Description

Technical Field

[0001] This utility model relates to the field of trolley case grinding technology, specifically a limiting grinding device for trolley case shells. Background Technology

[0002] A rolling suitcase is a type of luggage with a pull handle and wheels. It is widely used due to its convenience. Rolling suitcases can be categorized into hard-shell and soft-shell types based on their outer shell. Hard-shell suitcases are more durable and suitable for luggage requiring more protection; soft-shell suitcases are generally lighter and made of more flexible materials, but their zippers may burst open if the suitcase is overloaded.

[0003] Chinese patent application number CN202320638898.X discloses a limiting grinding device for trolley case shells. The trolley case to be ground can be placed flat on the turntable surface, and the pressure plate set above can be moved downward by the first hydraulic rod and pressed against the surface of the trolley case, improving the stability of the shell grinding. With the right-side moving mechanism, the outer wall of the trolley case shell can be ground. The turntable can be rotated by the first motor, thereby changing the orientation of the trolley case and ensuring that all four sides of the shell can be ground, greatly improving the grinding efficiency.

Through the arrangement of the material discharge channels 17 and the waste collection box 18, the waste generated by grinding the case shell can be discharged, which is conducive to the collection of the discharged waste and facilitates the subsequent cleaning of the waste by the staff.

[0032] It should be noted that: in this technical solution, the internal support adjustment component 154, the side end pressing component 155, and the side edge pressing component 156 are used in combination; when the structure is adjusted to the vertical state, it fits perfectly with the outer contour surface of the placed shell. The structure involved in this technical solution is a shell grinding device designed for a specific size trolley case.

[0033] In use, the operator first places the suitcase shell to be polished onto the surface of the placement seat 153. Then, the operator activates the telescopic controller 1542 via the polishing control panel 13 to extend the hydraulic telescopic rod 1541, thereby moving the top holding pad 1545 to the top of the inner side of the suitcase shell to hold it in place. Next, the operator activates the two ends of the electrically controlled double-ended telescopic rod 1543 via the inner support controller 1544 to extend simultaneously, thereby moving the inner support plate 1546 to support and fix the inner side of the suitcase shell. Then, the operator activates the two sets of side-end pressing components 155 via the polishing control panel 13. The operator then controls the first servo motor 1553 to rotate via the first pressing controller 1554, thereby rotating the first rotating rod 1552 and the first pressing rod 1555, causing the first pressing rod to rotate. One end of the holding rod 1555 is pressed against the end face of the suitcase shell.

The electric lifting rod 165 is extended by the lifting controller 166, which drives the shell grinder 168 to move down to the surface of the suitcase shell to be ground. Then, the top of the suitcase shell is ground. Then, the third servo motor 1610 is controlled by the adjustment controller 1611 to drive the shell grinder 168 to rotate, and then the sides of the suitcase shell are ground.

[0034] After the top and sides of the suitcase shell are polished, the side end holding member 155 is rotated and opened by the polishing control panel 13. Then, the two sets of side holding members 156 are controlled to hold the suitcase shell. Then, the second servo motor 1563 is controlled by the second holding controller 1564 to drive the second rotating rod 1562 to rotate, which in turn drives the second holding rod 1565 to rotate and press against the side of the suitcase shell. Then, the rotation controller 152 is started by the polishing control panel 13 to control the rotation controller 152 to rotate, which in turn drives the end face of the suitcase shell to the polishing position. Then, the polishing adjustment component 16 is started by the polishing control panel 13 to polish the end face of the suitcase.

[0035] During the processing, some of the waste generated during grinding is discharged through the feeding channel 17 into the waste collection box 18 for collection. When it is necessary to clean up the waste, the staff can simply remove the waste collection box 18 from the grinding table 11.
