Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a carton cardboard edge grinding machine. Background Art

[0002] During the processing and production of carton cardboard, edge grinding operation needs to be carried out on it. The purpose is to make the edges of the cardboard smoother, remove burrs, improve product quality, and a grinding machine is required when performing edge treatment on carton cardboard.

[0003] In order to improve the applicability of the grinding machine when grinding the edges of carton cardboard, many improvements have been made to the carton cardboard edge grinding machine in the prior art. For example, the patent with the publication number CN220902837U discloses a carton cardboard edge grinding machine, including a workbench. An installation groove is opened in the middle of the upper end of the workbench, and a transmission belt is arranged inside the installation groove. Adjusting mechanisms are arranged on the left front, right front, left rear, and right rear of the workbench. The upper ends of the two adjusting mechanisms in the front and the upper ends of the two adjusting mechanisms in the rear are all fixedly connected with a grinding mechanism together. Three fixing mechanisms are fixedly connected together in the middle of the front end and the middle of the rear end of the workbench. For the carton cardboard edge grinding machine described in the utility model, by arranging two adjusting mechanisms at the lower ends of the two grinding mechanisms, when the device is in use, according to the length or width of the cardboard to be ground, the grinding position of the grinding mechanism can be adjusted through the two adjusting mechanisms, so that the device can be adapted to grind cardboard of different specifications and sizes, and the practicability of the device can be improved.

[0004] The above patent has obvious beneficial effects, but there are still the following deficiencies in actual operation:

[0005] In the above comparative document, the edges of the cardboard are ground by a rotating grinding sand belt.

The driving unit 4 includes a number of first rotating shafts 8 passing through the carrier frame 1. Two symmetric first rotating rollers 9 are provided on the side of each first rotating shaft 8. The conveyor belt 2 is sleeved between the sides of the two symmetric first rotating rollers 9. The ends of the two first rotating shafts 8 penetrate the carrier frame 1 and extend to the outside. First gears 10 that mesh with each other are fixedly connected to the sides of the ends of the two first rotating shafts 8 extending to the outside. A first driving motor 11 for driving the first rotating shaft 8 to rotate is fixedly installed on the side of the carrier frame 1. The first grinding unit 5 includes a number of second rotating shafts 12 rotatably connected to the opposite sides of each set of carrier frames 1. A second rotating roller 13 is fixedly connected to the side of each second rotating shaft 12. A first grinding sand belt 14 for grinding is sleeved between the sides of the two second rotating rollers 13. Second gears 15 that mesh with each other are fixedly installed on the sides of the ends of the two second rotating shafts 12. A second driving motor 16 for driving the second rotating shaft 12 to rotate is fixedly installed on the carrier frame 1. The second grinding unit 6 includes a fixed plate 17 fixedly connected to the side of the carrier frame 1. Two symmetric third rotating shafts 18 are rotatably connected to the fixed plate 17. A third rotating roller 19 is fixedly connected to the side of each of the two third rotating shafts 18. A second grinding sand belt 20 adapted to the side of the cardboard body 3 is sleeved between the sides of the two third rotating rollers 19.

[0030] Specific implementation method in this embodiment: When it is necessary to polish the edge part of the cardboard body 3, first, according to the width of the cardboard body 3 to be polished, the distance between the two carrier frames 1 is adjusted through the adjusting unit 7. Then, the first driving motor 11 is started, and the output end of the first driving motor 11 drives one of the first rotating shafts 8 to rotate. At the same time, driven by the first gears 10 fixedly installed on the sides of the two first rotating shafts 8 and meshing with each other, the conveyor belts 2 on the two carrier frames 1 rotate in the reverse direction. One end of the cardboard body 3 is inserted between the conveyor belts 2, and the conveyor belts 2 drive the cardboard body 3 to move. The second driving motor 16 and the third driving motor 21 are started. The output end of the second driving motor 16 drives one of the second rotating shafts 12 to rotate. At the same time, the second gears 15 fixedly installed on the sides of the two second rotating shafts 12 and meshing with each other drive the first polishing sand belt 14 to rotate. When the cardboard body 3 moves between the two first polishing sand belts 14, the first polishing sand belts 14 polish the edges of the upper and lower surfaces of the cardboard body 3. The output end of the third driving motor 21 drives the third rotating shaft 18 to rotate, and the third rotating shaft 18 drives the third rotating roller 19 to rotate, thereby driving the second polishing sand belt 20 to rotate along the two third rotating rollers 19. When the cardboard body 3 moves to the position of the two second polishing sand belts 20, the two second polishing sand belts 20 polish the opposite sides of the cardboard body 3. One movement can complete the polishing of the edge part of the cardboard body 3, improving the efficiency of edge polishing of the cardboard body 3.
