Description

Technical Field

[0001] The utility model belongs to the field of paper boxes, and in particular relates to a creasing machine for producing corrugated paperboards. Background Art

[0002] Corrugated paper boxes are the most widely used packaging products, and their usage has always been the first among all kinds of packaging products. Corrugated paper is a rigid paper container made of corrugated cardboard through die-cutting, creasing, nailing or gluing. More than half a century later, corrugated paper boxes have gradually replaced wooden boxes and other transport packaging containers with their superior performance and good processing performance, becoming the main force of transport packaging. In addition to protecting goods and facilitating storage and transportation, they also play a role in beautifying goods and promoting commercial products. Corrugated paper boxes are green and environmentally friendly products, which are beneficial to the environment and convenient for loading and unloading.

[0003] When corrugated boxes are folded in half, they are relatively hard, so they need to be indented with the help of a creasing machine to facilitate the folding of the boxes. However, when the creasing machine is working, the depth of the indentation is generally fixed. For thicker corrugated boxes, this depth cannot meet the folding requirements. For thinner corrugated boxes, this depth is too deep, which causes damage to the indentation of the corrugated boxes and reduces the strength of the corrugated boxes. Moreover, nowadays, corrugated boxes are generally loaded and unloaded manually, which not only greatly increases the workload of the staff, but also reduces the production efficiency of corrugated boxes.

[0020] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0021] As shown in Figures 1-3, a creasing machine for corrugated board production includes a workbench 10, characterized in that: a conveying mechanism is provided on the workbench 10, a lower pressing plate 16 is also fixedly connected to the workbench 10, the conveying mechanism passes through the lower pressing plate 16, a bracket 17 is also provided on the upper end surface of the workbench 10, the bracket 17 is located at the lower pressing plate 16, a hydraulic system 20 is installed on the upper side of the bracket 17, and a creasing assembly is installed on the side of the hydraulic system 20 close to the workbench 10;

[0022] The transmission mechanism includes two transmission wheels 11, one of which is equipped with a motor 12, the motor 12 is fixed on the workbench 10, and a transmission belt 13 is sleeved on the two transmission wheels 11, and a plurality of raised pads 14 and blocking balls 15 are arranged on the outer peripheral side of the transmission belt 13;

[0023] The indentation assembly includes an upper pressure plate 19 detachably mounted with a hydraulic system 20, an adjustment cavity 21 is provided on one end face of the upper pressure plate 19 close to the workbench 10, a thread groove 22 is also provided in the adjustment cavity 21, a connecting plate 23 is slidably provided in the adjustment cavity 21, an adjusting bolt 24 is rotatably connected to the middle part of the connecting plate 23, the adjusting bolt 24 is threadedly connected to the thread groove 22, at least two indentation convex strips 25 are provided on one end face of the connecting plate 23 close to the workbench 10, and the length of the indentation convex strips 25 is greater than the length of the adjusting bolt 24 leaking downward from the connecting plate 23 When the indentation convex strip 25 is indenting, the adjusting bolt 24 is prevented from contacting the corrugated cardboard to damage the corrugated cardboard. Moreover, by setting the adjusting bolt 24, on the one hand, the connection plate 23 can be easily disassembled and replaced, and it can adapt to corrugated cardboards that require different indentations. On the other hand, since the stroke of the indentation component is a fixed distance, the position of the connection plate 23 can be adjusted by adjusting the adjusting bolt 24, so as to adjust the indentation depth of the indentation convex strip 25, so that it can adapt to the different indentation depths required by corrugated cardboards of different thicknesses.

[0024] The lower pressing plate 16 is fixedly connected to the end surface of one side away from the workbench 10 with four slide bars 18, and the slide bars 18 are located at the four corners of the lower pressing plate 16, and the slide bars 18 extend upward into the upper pressing plate 19, and are slidably connected to the upper pressing plate 19. The setting of the slide bars 18 can effectively increase the stability of the indentation assembly, and it also has a certain guiding function. The lower pressing plate 16 is provided with a through hole along the length direction of the workbench 10, and two arc-shaped grooves are opened on the top of the through hole. The raised pads 14 and the blocking balls 15 are grouped in pairs, and each group of raised pads 14 and each group of blocking balls 1 5 are staggered, and the raised pads 14 and the blocking balls 15 can be located in the arc-shaped grooves, and the height of the blocking balls 15 is greater than that of the raised pads 14. The arc-shaped grooves facilitate the passage of the raised pads 14 and the blocking balls 15, and the blocking balls 15 can automatically push the corrugated cardboard to perform autonomous loading and unloading, thereby reducing the tediousness of manual operation. The raised pads 14 can also prevent the corrugated cardboard from being on the conveyor belt 13 with one end in a tilted state, so that the corrugated cardboard is more easily pushed onto the lower pressing plate 16 for indentation treatment.

[0025] When in use, first start the motor 12 to make the conveying mechanism run, the conveyor belt 13 starts to convey, and then place the corrugated cardboard on the conveyor belt 13, so that one end of the corrugated cardboard abuts against the blocking ball 15, its bottom will be pressed on the raised pad 14, and the other end will be tilted. During the transportation of the conveyor belt 13, the corrugated cardboard is gradually pushed automatically to the upper surface of the lower pressure plate 16, and then the hydraulic system 20 is started to drive the indentation component to be pressed down as a whole to indent the corrugated cardboard. After the indentation is completed, the next corrugated cardboard is also pushed onto the lower pressure plate 16, that is, the current corrugated cardboard is pushed and dropped, and the automatic unloading is completed, which greatly facilitates the operation of the staff and increases the manufacturing efficiency of the corrugated cardboard.

[0026] When the corrugated cardboard is thicker and a deeper indentation is required, the adjusting bolt 24 is screwed downward to move the connecting plate 23 downward, so that the height of the indentation ridge 25 from the corrugated cardboard can be reduced, but the stroke of the indentation assembly remains unchanged, so the indentation depth can be increased at this time, and vice versa, the indentation depth can be reduced, making the adjustment of the indentation depth more convenient and simple.

[0027] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
