DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The following will Figures 1 to 3 describe the present utility model in detail with reference to the attached
[0023] The utility model discloses an adjustable label trimming knife frame structure, comprising a base 1 and a cutter assembly 2, wherein a left mounting plate 11 and a right mounting plate 12 are respectively arranged on both sides of the base 1, and the cutter assembly 2 is arranged between the left mounting plate 11 and the right mounting plate 12, and further comprising a driving motor 3 and a driving shaft 4, wherein the driving shaft 4 is arranged below the cutter assembly 2, and an eccentric wheel 41 is installed at the end of the driving shaft 4; the driving motor 3 is connected to the driving shaft 4 in a transmission manner; the left mounting plate 11 and the right mounting plate 12 are both provided with a first swing arm assembly 5, and the first swing arm assembly 5 comprises a swing arm a51, wherein the middle part of the swing arm a51 is movably connected to a mounting plate, namely, the left mounting plate 11 or the right mounting plate 12, and a swing wheel 52 is installed at the lower end of the swing arm a51, and the upper end is connected to the cutter assembly 2.
[0024] When the cutting angle of the cutter assembly 2 needs to be adjusted, the driving motor 3 drives the driving shaft 4 to rotate, driving the eccentric wheel 41 to rotate. At this time, the eccentric angle of the eccentric wheel 41 abuts against the swing wheel 52 and lifts the swing wheel 52, causing the swing arm a51 to swing, driving the cutter assembly 2 to swing and thereby adjusting the cutting angle position.
[0025] Compared with the traditional trimming assembly, the utility model has the following advantages: 1. The eccentric wheel is used to drive the trimming tool holder to swing, so that the trimming tool can automatically and efficiently adjust the angle position, and manual disassembly and adjustment are no longer required, which can ensure that the production efficiency of the label is not affected; 2. The position of the tool holder can be adjusted automatically and flexibly, which can save a lot of manpower and material resources and reduce production costs.
[0026] As a preferred example, Figure 1 As shown, the left mounting plate 11 and the right mounting plate 12 are both provided with an arc groove 13, and the two ends of the cutter assembly 2 are both provided with a sliding shaft 14, and the sliding shaft 14 passes through the arc groove 13. At this time, the swing arm a51 swings along the arc groove 13, so that the swing trajectory of the swing arm a51 is limited, and the entire tool adjustment process is more stable.
[0027] In order to further improve the stability of the adjustment of the cutter assembly 2 , a second swing arm assembly 6 is provided at the other end of the sliding shaft 14 .
[0028] Preferably, the second swing arm assembly 6 includes a swing arm b61, one end of which is movably connected to the mounting plate, and the other end is connected to the sliding shaft 14. The two swing arm assemblies on both sides of the mounting plate cooperate to effectively prevent the sliding shaft 14 from being separated from the arc groove 13, and further improve the stability of the cutter assembly 2 adjustment.
[0029] As an embodiment, a swing arm c62 is further disposed between the swing arm b61 and the sliding shaft 14. One end of the swing arm c62 is movably connected to the mounting plate, the other end is connected to the sliding shaft 14, and the middle of the swing arm c62 is connected to the swing arm b61. The second swing arm assembly 6 mainly follows the movement of the first swing arm assembly 5 and requires a certain degree of flexibility. The addition of the swing arm c62 to the second swing arm assembly 6 makes the swing action of the second swing assembly consist of two movable arms, thereby improving the flexibility of the second swing arm assembly 6.
[0030] Preferably, the swing arm a51 and the second swing arm b61 are both connected with a return spring 7. When the cutter assembly 2 needs to return to the original angle, the eccentric wheel 41 disengages from the swing wheel 52. At this time, the return spring 7 can be used to drag the swing arm assemblies on both sides of the mounting plate back quickly for reset.
[0031] As an embodiment, the swing arm a51 is arranged in an "L" shape, that is, the swing arm a51 is bent. Compared with a straight swing arm, it can effectively reduce the occupied space of the swing arm and improve the space utilization rate.
[0032] In this technical solution, the cutter assembly 2 includes a cutter shaft 21 and a plurality of trimming knives 22 disposed on the cutter shaft 21. The trimming knives 22 are movably connected to the cutter shaft 21. The first swing arm assembly 5 and the second swing arm assembly 6 realize the axial adjustment of the cutter assembly 2, while the trimming knives 22 and the cutter shaft 21 can realize the lateral adjustment, so that the cutter assembly 2 can realize the omnidirectional adjustment.
[0033] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present invention.
