Description

Technical Field

[0001] This utility model relates to the technical field of cardboard processing equipment, and in particular to a cardboard creasing wheel. Background Technology

[0002] Cardboard creasing machines are used in the production of corrugated boxes. By creasing the cardboard, subsequent folding becomes simpler, simplifying the process, facilitating maintenance, and improving efficiency. For example, a cardboard creasing machine proposed in existing technology announcement number CN211843406UU includes a feeding module, a creasing module, a discharging module, and a control module. The creasing rollers are an indispensable processing component of the creasing machine. Currently, in most domestic models, the lower roller is an iron roller (there are two types of iron rollers: trapezoidal rollers, whose disadvantage is unclear creasing lines and easy deviation of the box height line; and convex rollers, whose disadvantage is that the pressure cannot be too high, otherwise the creasing will burst), and the upper roller is a plastic roller (the plastic used is a very hard adhesive with a hardness of 90-95, the disadvantage of which is that it is impossible to achieve negative pressure distance). The upper and lower rollers then squeeze from both sides. Insufficient force will not leave a crease, while excessive force will easily squeeze the cardboard and burst the creasing. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a cardboard creasing roller that reduces the lateral stretching of cardboard, avoids the occurrence of cracking, greatly reduces enterprise costs, and ensures the precision and aesthetics of the packaging material.

[0004] This utility model discloses a cardboard creasing wheel, comprising a lower metal wheel frame, an upper metal wheel frame, a rubber ring, and a rubber ring. The lower metal wheel frame has recessed grooves on both sides of its outer wall, with a textured surface. The rubber ring is installed within each groove, and a creasing line is formed between the two recessed grooves. The upper metal wheel frame has a groove in the middle of its outer wall, with a textured surface. The rubber ring is installed within the groove. The textured surface allows the rubber ring to adhere more tightly to the lower metal wheel frame. Simultaneously, the textured surface in the groove increases the friction between the rubber ring and the upper metal wheel frame, resulting in a better fit. During operation, the center line of the two sets of wheels is compressed, naturally forming a concave-convex wrapping principle. This improvement reduces lateral stretching of the cardboard, preventing creasing and ensuring more stable shaping of the box height line. It can press the cardboard to a negative distance, achieving a scientifically sound load-bearing effect. The finished product significantly reduces bulging, greatly lowering enterprise costs while ensuring the packaging material's precision and aesthetics.

[0005] Preferably, the crease line is higher than the rubber rings on both sides, and the rubber rings are higher than the upper metal wheel frame; the cardboard enters between the upper and lower wheels, and is squeezed upward by the crease line. The crease line and the upper rubber ring perform a crease action, which will naturally form a concave-convex wrapping principle.

[0006] Preferably, the adhesive ring is made of soft rubber with a rough, textured outer surface; this increases friction and prevents the cardboard from tilting.

[0007] Preferably, the lower metal wheel frame and the upper metal wheel frame are circles composed of two semicircles, and the lower metal wheel frame and the upper metal wheel frame are provided with multiple bolt holes, and the inner ring is provided with a spline groove; the lower metal wheel frame and the upper metal wheel frame are fixedly connected by fasteners through bolt holes and spline grooves, which facilitates installation on the machine spindle.

[0008] Compared with the existing technology, the beneficial effects of this utility model are as follows: During operation, the middle line of the two sets of wheels is squeezed, which will naturally form a concave-convex wrapping principle. After the improvement, the lateral stretching of the cardboard will be reduced, and the bursting of the line will be avoided. The box height line is more stable in forming, and the cardboard can be pressed out to a negative distance, thereby achieving a very scientific bearing effect. When the finished product is finished, the bulging will be greatly reduced, which will greatly reduce the enterprise cost while ensuring the precision and beauty of the packaging material.

[0015] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0016] like Figures 1 to 5As shown, the lower metal wheel frame 1 has recessed grooves on the left and right sides of its outer wall. The groove surface is rough. A rubber ring 4 is installed in the recessed groove. There is an indentation line 3 between the two recessed grooves. The upper metal wheel frame 2 has a groove in the middle of its outer wall. The groove surface is rough. A rubber ring 5 is installed in the groove. The indentation line 3 is higher than the rubber rings 4 on both sides. At the same time, the rubber ring 5 is higher than the upper metal wheel frame 2. The rubber ring 4 is made of soft rubber. The outer rubber surface is rough. The lower metal wheel frame 1 and the upper metal wheel frame 2 are circles composed of two semicircles. There are multiple bolt holes 6 on the lower metal wheel frame 1 and the upper metal wheel frame 2. A spline groove 7 is provided on the inner ring.

[0017] The textured surface allows the rubber ring 4 to adhere more tightly to the lower metal wheel frame 1. At the same time, the textured surface in the groove increases the friction between the rubber ring 5 and the upper metal wheel frame 2, making them fit better. During operation, the center line of the two sets of wheels is squeezed, and the cardboard enters between the upper and lower wheels. It is squeezed upward through the indentation line 3. The indentation line 3 and the upper rubber ring 5 make an indentation action, which will naturally form a concave-convex wrapping principle. The rubber ring 4 is made of soft rubber material, and the outer rubber surface is rough and textured, which can increase friction and prevent the cardboard from slipping. The lower metal wheel frame 1 and the upper metal wheel frame 2 are fixedly connected by fasteners through bolt holes 6 and spline grooves 7, which facilitates installation on the machine spindle.

[0018] like Figures 1 to 5 As shown, this utility model is a cardboard creasing roller. When in use, the cardboard enters between the upper and lower rollers and is squeezed upward by the creasing line 3. The creasing line 3 and the upper rubber ring 5 perform creasing action. In order to make the creasing pressing better, a set of pre-pressing rollers are usually set at the front end for positioning and creasing. First, a thickness is pressed, and then the second pressing is performed, which is completed in one step.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
