[0021] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model proposes a creasing device for corrugated cardboard boxes, including a processing table 1, see reference. Figure 1 The processing table 1 has a feeding end and a discharging end on its left and right sides, respectively. Conveyor belts are provided outside the feeding end and the discharging end. The feeding end of the processing table 1 is provided with two feeding rollers 11 arranged vertically. One end of the feeding roller 11 is connected to a feeding motor 111. The rotation of the feeding roller 11 can push the cardboard to the center of the processing table 1. The discharging end of the processing table 1 is provided with a baffle roller 12. The baffle roller 12 is provided with a baffle strip 121, which is used to limit the forward movement of the cardboard. One end of the baffle roller 12 is connected to a discharging motor 122. Two adjusting grooves 13 are symmetrically provided on the processing table 1.

[0024] See Figure 2 The processing table 1 is fixed with a creasing bracket 2. The top of the creasing bracket 2 is provided with a lifting cylinder 21. The lower end of the lifting cylinder 21 is fixed with a carrier plate 22. The two sides of the carrier plate 22 are provided with pressure plates 23. A spring 24 is provided between the carrier plate 22 and the pressure plates 23. The two ends of the spring 24 can be fixedly connected to the carrier plate 22 and the pressure plates 23 respectively. The lower surface of the carrier plate 22 is provided with a plurality of creasing knives 25. When the lifting cylinder 21 controls the carrier plate 22 to move down, the pressure plates 23 first contact the cardboard and gradually compress the spring 24. Then the creasing knives 25 contact the cardboard to achieve creasing.

[0025] Two symmetrically arranged guide plates 3 are located between the creasing bracket 2 and the feed roller 11. The guide plates 3 are used to guide the paperboard to move along a predetermined path. The guide plates 3 are provided with linkage bosses 31 and several guide wheels 32. The linkage bosses 31 are slidably connected in the adjustment groove 13. A linkage adjustment component 33 is provided between the two linkage bosses 31. The linkage adjustment component 33 can make the two guide plates 3 move inward or outward at the same time to change the distance between the guide plates 3 and adapt to the processing of paperboards of different widths.

[0026] During operation, multiple sheets of cardboard can travel between the feed roller 11 and the stop roller 12. When the rightmost cardboard comes into contact with the stop strip 121, the feed roller 11 stops rotating. Then, the carrier plate 22 moves down to complete the creasing. The stop roller 12 and feed roller 11 then rotate simultaneously, and the stop strip 121 no longer obstructs the cardboard's progress. The processed cardboard is pushed to the contact position with the conveyor belt by the subsequent cardboard and is then conveyed for unloading. At this point, there is no cardboard above the stop roller 12. The stop roller 12 then rotates, causing the stop strip 121 to return to its original position. The feed roller 11 then pushes the cardboard to continue into the processing position, and this cycle repeats. The cardboard to be processed is positioned by the guide plate 3, and the travel distance is limited by the stop strip 121. Finally, the pressure plate 23 assists in the processing and positioning, ultimately ensuring that the cardboard can be accurately creasing.

[0027] See Figure 3 The carrying plate 22 has several guide holes 221 symmetrically arranged on both sides, and the pressure plate 23 has several guide rods 231. The guide rods 231 are slidably connected to the guide holes 221 to ensure the stability of the movement direction of the pressure plate 23. The spring 24 is sleeved on the guide rods 231. The upper end of the guide rods 231 can be provided with a limiting block or a limiting boss can be directly formed to prevent the guide rods 231 from sliding out of the guide holes 221.

[0028] See Figure 3 The carrier plate 22 is symmetrically provided with a number of sets of connecting holes 222, and the indentation knife 25 is provided with a number of connecting threaded holes 251. Connecting bolts are provided in the connecting holes 222. The indentation knife 25 is fixed to the carrier plate 22 by connecting bolts and connecting threaded holes 251. By selecting different positions of the connecting holes 222, the user can set multiple sets of indentation knives 25 with different spacings on the carrier plate 22.

[0029] See Figure 1 , 2The discharge end of the processing table 1 is provided with a relief groove 14, and support plates 141 are provided on both sides of the relief groove 14. The support plates 141 are located on the lower surface of the processing table 1. The baffle roller 12 is rotatably connected between the support plates 141. The rotation of the baffle roller 12 can move the baffle strip 121 to below the processing table 1 to realize the control of the paperboard movement.

[0030] See Figure 2 , 4 The linkage adjustment assembly includes a double-ended screw 331 and a linkage motor 332. The linkage motor 332 is fixed on the processing table 1. The threads at both ends of the double-ended screw 331 are in opposite directions. The linkage boss 31 is provided with an internal threaded hole 311. The end of the double-ended screw 331 is inserted into the internal threaded hole 311. When the double-ended screw 331 rotates, under the effect of thread transmission, the two linkage bosses 31 move inward and outward at the same time to realize the adjustment of the spacing of the guide plate 3. The double-ended screw 331 has a linkage gear 333 at its center. The linkage motor 332 has a drive gear 334 that meshes with the linkage gear 333. The linkage gear 333 has bearings 335 on both sides. The processing table 1 has two limiting plates 15 spaced apart on its lower surface. The double-ended screw 331 is rotatably connected to the limiting plates 15. The linkage gear 333 and the bearings 335 are located between the two limiting plates 15. The two bearings 335 abut against the limiting plates 15 on both sides, thereby ensuring that the lateral position of the linkage gear 333 and the double-ended screw 331 remains unchanged.

[0031] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
