Description

Technical Field

[0001] This application relates to the technical field of packaging box manufacturing, and in particular to a packaging box trimming machine. Background Technology

[0002] During the production of packaging boxes, the edges often need to be trimmed to ensure the product's appearance is neat and the dimensions are accurate. Traditional trimming equipment uses fixed cutting blades to trim the edges of cardboard. The blades are brought into contact with the moving cardboard through mechanical pressure or friction, and the relative motion is used to complete the cutting. Fixed blades rely on the speed of the moving cardboard to achieve cutting, which is prone to rough cuts due to speed fluctuations. They are not compatible with high-hardness or composite cardboard, and the increased cutting resistance can cause the cardboard to deform or even tear.

[0003] Therefore, those skilled in the art have provided a packaging box trimming machine to solve the problems mentioned in the background art. Utility Model Content

A cutting blade 8 is mounted on the outside of the first drive rod 7. A protective shell 24 is mounted on the other side of the mounting frame 1. A second motor 23 is mounted on the lower side of the protective shell 24. The second motor 23 outputs... The output end is fixedly connected to the first drive rod 7. The first motor 11 is installed on the upper side of the protective shell 24. The output end of the first motor 11 is equipped with a second gear 10. The outer side of the second gear 10 is equipped with a first gear 9. The first gear 9 is installed on the outer side of the first tube 5 near the other end. The second tube 13 is installed on the inner side of the mounting bracket 1 and below the mounting rod 3. Two second drive wheels 14 are installed on the outer side of the second tube 13. The outer side of the second tube 13 near the other end is equipped with a third gear 12. The third gear 12 meshes with the first gear 9.

[0021] The first motor 11 drives the second gear 10 to rotate. The second gear 10 meshes with the first gear 9 and the third gear 12, driving the first tube 5, the first drive wheel 6, the second tube 13 and the second drive wheel 14 to rotate, thus moving the cardboard of the packaging box. The second motor 23 drives the cutting blade 8 on the first drive rod 7 to rotate, cutting and trimming the edges of the cardboard of the packaging box.

[0022] like Figure 1-4As shown, a housing 16 is installed at the end of the second tube 13. A second drive rod 17 is installed on the inner side of the second tube 13. A turbofan 18 is installed on the outer side of the second drive rod 17 and inside the housing 16. Synchronous pulleys 21 are respectively installed on the outer ends of the second drive rod 17 and the first drive rod 7. A synchronous belt 22 is installed between the outer sides of the two synchronous pulleys 21. Several annularly arranged through holes 15 are opened through the side wall of the second tube 13 and between the two second drive wheels 14. The second motor 23 drives the first drive rod 7 and the synchronous pulleys 21 to rotate. The second drive rod 17 is driven by the synchronous belt 22 in conjunction with the synchronous pulleys 21, which drives the turbofan 18 on the second drive rod 17 to rotate, drawing outside air into the housing 16 and discharging it through the through holes 15, thus clearing the blockage that is blocking the gap between the two second drive wheels 14.

[0023] like Figure 2 , 4 As shown, a filter screen 19 is installed at the air inlet end of the housing 16, and a cleaning brush 20 is installed on the outside of the second drive rod 17 near the filter screen 19.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] The implementation principle of a packaging box trimming machine according to an embodiment of this application is as follows:

[0029] In use, the cardboard is placed on the support plate 2 and manually pushed into the drive wheel area. The first motor 11 drives the second gear 10 to mesh with the first gear 9, causing the first tube 5 and the first drive wheel 6 to rotate. At the same time, the second gear 10 drives the second tube 13 and the second drive wheel 14 to rotate in the opposite direction through the third gear 12. The driven wheel 4 and the first drive wheel 6 are both located at the top of the cardboard, cooperating with the second drive wheel 14 to clamp the cardboard and convey it at a uniform speed. The second motor 23 drives the first drive rod 7 and the cutting blade 8 to rotate at a high speed, higher than the drive wheel. The cardboard passes through... When passing through the gap between the cutting blade 8 and the second drive wheel 14, the edge cutting is completed. The cutting blade 8 is embedded in the gap between the two second drive wheels 14 to ensure the trimming accuracy. The second drive rod 17 is driven by the first drive rod 7 through the synchronous wheel 21 and the synchronous belt 22, which drives the turbo fan 18 to rotate and draw in air from the air inlet end of the housing 16. After the airflow is filtered by the filter screen 19, it is ejected at high speed through the annular through hole 15 to blow away the debris in the gap between the second drive wheels 14. The cleaning brush 20 rotates with the second drive rod 17 to simultaneously remove the adhering substances on the surface of the filter screen 19 and maintain smooth airflow.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
