In the manufacturing process of the shoe box, two grooves need to be symmetrically formed in the paper board so that the paper board can be folded to form the shoe box, and the grooving processing of the paper board is usually carried out through paper board grooving equipment.

In the related art, as shown in fig. 1, a paperboard slotting device includes a frame 1, a conveyor belt 13 for conveying a paperboard, an overturning roller 14 and a plurality of conveyor rollers 15 rotatably connected to the frame 1, a plurality of conveyor belts 16, and a slotting cutter 4 for slotting the paperboard, where each conveyor belt 16 is sleeved on each conveyor roller 15. The frame 1 is provided with a fixing plate 17 and a positioning plate 18, and the fixing plate 17 and the positioning plate 18 are both positioned above the conveyor belt 13. The positioning plate 18 and the fixing plate 17 are respectively located at two sides of the conveying direction of the conveying belt 13 and are respectively used for abutting against two sides of the paper board, and the positioning plate 18 is arranged on the rack 1 in a sliding mode along the direction close to or far away from the fixing plate 17. When slotting the cardboard, need convey cardboard to upset roller 14 department through conveyer belt 13, rethread upset roller 14 and upset belt upset cardboard, the cardboard is contradicted with slotting tool 4 at the in-process of upset to it slots on the cardboard through slotting tool 4.

With respect to the related art among the above, the inventors consider that the following drawbacks exist: after the width of the paperboard to be processed is changed, the distance between the fixing plate and the positioning plate needs to be adjusted, the position of the slotting cutter on the rack needs to be adjusted, the equipment adjusting process is complicated, and the equipment adjusting time consumption is long and needs to be improved.

Disclosure of Invention

In order to reduce the equipment adjustment after changing the cardboard to be processed consuming time, the application provides a shoes box cardboard fluting equipment.

The application provides a shoes box cardboard fluting equipment adopts following technical scheme:

the utility model provides a shoes box cardboard fluting equipment, includes the frame and sets up the conveyer belt in the frame, still includes fixed plate, locating plate and slides the knife rest that sets up in the frame, fixed plate and locating plate all are located the top of conveyer belt, the locating plate slides along the direction of being close to or keeping away from the fixed plate and sets up in the frame, the knife rest is unanimous with the slip direction of locating plate, it is provided with two slotting tools, two to slide in opposite directions or back of the body mutually on the knife rest slotting tool is unanimous with the interval of knife rest central line, be provided with the link gear who is used for driving locating plate and knife rest syntropy to remove in the frame, through when link gear drive locating plate and knife rest removed, the displacement distance of locating plate is the twice of knife rest.

Through adopting above-mentioned technical scheme, after changing and waiting to process the cardboard, put the cardboard on the conveyer belt earlier to through link gear slip locating plate, conflict with fixed plate and locating plate respectively until the both sides of cardboard. And meanwhile, the linkage mechanism also drives the tool rest to slide by half of the displacement distance of the positioning plate, so that the center line of the tool rest can be always positioned in the middle plane of the positioning plate and the fixing plate. Because the distance between the two grooves to be formed on the paperboard is consistent with the distance between the central lines of the paperboards, the operators only need to slide the slotting tools in the opposite directions or back to adjust the distance between the two slotting tools according to the distance between the two grooves to be formed.

Compared with the method that after the paperboard to be processed is changed, the positioning plate needs to be adjusted, and the positions of the two slotting cutters need to be adjusted according to the position of the paperboard on the turnover roller. Through the slotting device, the staff of being convenient for adjust the equipment, it is consuming time to have reduced the equipment adjustment after changing the cardboard of treating to process.
