Description

Technical Field

[0001] The invention relates to the technical field of automatic strapping machines, and in particular to a cutting mechanism for strapping materials. Background Art

[0002] Automatic strapping machines are currently widely used packaging equipment. They use film to achieve product strapping and packaging through steps such as tensioning, cutting, and strapping. During the automatic strapping process, the product needs to be fed into the strapping chamber and strapped by the film feeding device and the tightening device. After strapping is completed, the film is cut with a cutter, and the two ends of the film are fused together by heating. However, when the cable tie enters from the feed end of the cutting mechanism and passes over the top of the heating structure, the cable tie may also shift, which will also cause the head and end of the cable tie tied to the product to not completely overlap, the heating component cannot completely heat-glue the head and end of the cable tie together, and the cable tie is easy to break after the material mechanism cuts the cable tie.

[0030] Please review Figure 1As shown in the figure, in this embodiment, the cutting guide assembly 2 includes a mounting plate 21, a tape guide bracket 22, a tape guide member 23, a tape guide shaft 24 and a torsion spring 25. The tape guide bracket 22 is arranged above the mounting plate 21. An avoidance groove (not shown in the figure) is arranged at the upper end of the tape guide bracket 22. The tape guide member 23 is rotatably connected to the tape guide bracket 22 through the tape guide shaft 24. A tape guide groove 231 is arranged at the upper end of the tape guide member 23. The torsion spring 25 is sleeved on the tape guide shaft 24 and acts on the tape guide member 23 to make the tape guide member 23 approach the action surface of the cutting assembly 1. When cutting the tape material, the cutting knife block 131 of the cutting assembly 13 acts on the tape guide member 23, causing the tape guide member 23 to rotate and move away from the cutting assembly 1 through the avoidance groove, and the tape material leaves the tape guide groove 231.

[0031] Please review Figure 1 As shown in the figure, in this embodiment, the cutting guide assembly 2 also includes a reset spring 26 and an elastic rubber pad 27. One end of the reset spring 26 is connected to the mounting plate 21, and the other end is fixed to the device when in use. The elastic rubber pad 27 is connected to the mounting plate 21 and is arranged between the device and the mounting plate 21. During the rotation of the belt guide 23, the belt guide 23 squeezes the torsion spring 25, so that the torsion spring 25 acts on the belt guide bracket 22, and the belt guide bracket 22 moves slightly and squeezes the reset spring 26. The mounting plate 21 presses the elastic rubber pad 27. When the cutting and pressing group 14 is away from the belt guide 23, the reset spring 26 drives the belt guide bracket 22 to reset.

[0032] Please review Figure 1 As shown in the figure, in this embodiment, the cutting guide assembly 2 also includes a retaining ring 228, which is arranged at both ends of the tape guide shaft 24 for fastening the tape guide shaft 24 and the tape guide bracket 224.

[0033] In specific application, when the material belt is output by the conveying assembly and enters the material trough 1211 of the material lifting block 121, and then is conveyed to the cutting group 13 along the belt guide groove 231 on the belt guide member 23, after the material belt passes through the cutting group 13, the lifting drive group 16 is started, the lifting drive shaft 162 rotates and drives the first cam 163, the second cam 164 and the third cam 165 arranged on the lifting drive shaft 162 to rotate, and the first cam 163, the second cam 164 and the third cam 165 respectively drive the first shaft wheel 124, the second shaft wheel 134 and the third shaft wheel 135. The shaft wheel 144 rotates, causing the material lifting block 121, the cutting knife block 131 and the cutting and pressing slider 141 to rise along the cutting frame 11. During the rising process of the cutting knife block 131, the cutting knife block 131 presses the belt guide 23 upward, causing the belt guide 23 to rotate and move away from the cutting component 1 through the avoidance groove, and the belt leaves the belt guide groove 231. At the same time, the cutting heating group 15 follows the cutting and pressing slider 141 and presses down on the belt, so that the head end and the tail end of the belt packaged on the product are hot-bonded together, and then the knife head 1311 cuts the belt.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
