[0030] Figures 1 to 4 An embodiment of the capping device of the present invention is shown. Figure 1 and Figure 2As shown, the capping device of this embodiment includes a mounting seat 1, a connecting shaft 2 and a rolling cutter 3. The rolling cutter 3 is rotatably mounted on one end of the connecting shaft 2. The other end of the connecting shaft 2 is elastically connected to the mounting seat 1, and the connecting shaft 2 is also abutted against the mounting seat 1. The abutting surface is an arc surface. The mounting seat 1 is provided with an angle adjustment mechanism 4 for adjusting the angle of the connecting shaft 2, and the mounting seat 1 is provided with an avoidance space 5 for avoiding the angle change of the connecting shaft 2.
[0031] In the capping device, the abutting surface between the connecting shaft 2 and the mounting seat 1 is an arc surface, the angle of the connecting shaft 2 is adjusted by the angle adjustment mechanism 4, and the avoidance space 5 can avoid the angle change of the connecting shaft 2, so as to adjust the capping inclination angle of the rolling cutter 3. When the aluminum cap is too long, the rolling cover can be deeper and more edging can be wrapped, so as to meet the appearance requirements of the rolling cover, ensure the rolling cover effect, improve the quality of the rolling cover, and at the same time adapt to the rolling cover angle requirements of different bottle bodies, and have high adaptability; in addition, the connecting shaft 2 is elastically connected to the mounting seat 1, so that the rolling cutter 3 has a certain amount of activity in the height direction, which can adapt to the rolling cover of bottles with different bottle mouth heights to avoid bottle breakage.
[0032] Further, in this embodiment, the angle adjustment mechanism 4 includes a plurality of elastic adjustment components 6, which are arranged at intervals along the circumference of the mounting seat 1. The elastic adjustment components 6 include a first elastic member 61 and an adjustment member 62. One end of the first elastic member 61 is connected to the connecting shaft 2, and the other end is connected to the adjustment member 62. The adjustment member 62 is threadedly connected to the mounting seat 1. Tightening the adjustment member 62 squeezes the first elastic member 61, thereby pushing the connecting shaft 2 to deflect, and realizing the angle adjustment of the rolling cutter 3. There are a plurality of elastic adjustment components 6, and they are arranged at intervals along the circumference of the mounting seat 1, so that the angle adjustment in multiple directions can be realized. In addition, tightening the adjustment member 62 increases the pressing force of the rolling cutter 3, so that the rolling cutter 3 can roll thicker aluminum covers, ensuring the rolling effect. Specifically, there are three elastic adjustment components 6. When adjusting, according to the required adjustment angle, keep one of them unchanged and adjust the other two. Preferably, the abutment surface between the connecting shaft 2 and the mounting seat 1 is a spherical surface, which is suitable for multi-angle adjustment.
[0033] Furthermore, in this embodiment, a plurality of first limiting rods 21 are provided around the connecting shaft 2, and the first elastic members 61 are sleeved outside the first limiting rods 21 one by one. The first limiting rods 21 limit the extrusion direction of the first elastic members 61, which is beneficial to the accuracy of angle adjustment.
[0034] Furthermore, in this embodiment, the capping device further comprises a pressure regulating assembly 7, and the pressure regulating assembly 7 is used to adjust the capping force of the capping cutter 3. The capping device can adapt to bottles with different capping force requirements, and has good adaptability.
[0035] Further, in this embodiment, the pressure regulating assembly 7 includes a second elastic member 72 and a first adjusting nut 73, the first adjusting nut 73 is threadedly connected to the connecting shaft 2, and the second elastic member 72 is sleeved outside the connecting shaft 2 and located between the first adjusting nut 73 and the mounting seat 1. When adjusting, firstly lock the first adjusting nut 73, the second elastic member 72 tightens the connecting shaft 2, and then adjusts the capping angle and capping pressing force through the angle adjusting mechanism 4. Since the guillotine 3 is inclined, when the pressing force is large, the downward axial component force will also increase. At this time, the upward tensioning force of the second elastic member 72 can offset the downward axial component force, so that the guillotine 3 can press the edge upward to ensure the sealing performance, and adapt to bottles with different thicknesses and different bottle mouth heights; in addition, the connecting shaft 2 is elastically connected to the mounting seat 1 through the second elastic member 72, so that the guillotine 3 has a certain amount of activity in the height direction, which can adapt to bottles with different bottle mouth heights, realize the fine adjustment of the height of the blade, and avoid bottle breakage.
[0036] Furthermore, in this embodiment, a protective cover 74 is detachably provided on the mounting seat 1, and the protective cover 74 is provided outside the pressure regulating assembly 7. The pressure regulating assembly 7 is protected and the aesthetics are also improved.
[0037] Furthermore, in this embodiment, the capping device further comprises a guillotine arm 8, the mounting seat 1 is connected to the guillotine arm 8, and the guillotine arm 8 is provided with a height adjustment component 9 for adjusting the connection height of the mounting seat 1. The height of the mounting seat 1 is adjusted by the height adjustment component 9. Thus, the capping height of the guillotine 3 is adjusted to meet the capping requirements of bottles of different specifications.
[0038] Furthermore, in this embodiment, the height adjustment assembly 9 includes an adjustment screw 91, a third elastic member 92 and a second adjustment nut 93. The two ends of the adjustment screw 91 are connected to the guillotine arm 8 and the mounting seat 1 respectively. The third elastic member 92 is located between the guillotine arm 8 and the mounting seat 1 and is sleeved outside the adjustment screw 91. The second adjustment nut 93 is threadedly connected to one end of the adjustment screw 91 and abuts against the outside of the guillotine arm 8. The other end of the adjustment screw 91 is provided with a limiter 94, and the limiter 94 abuts against the outside of the mounting seat 1. The third elastic member 92 is tightened by locking the second adjustment nut 93, thereby increasing the height of the mounting seat 1 and the height of the guillotine cover. Loosening the third elastic member 92 is the opposite. At the same time, the third elastic member 92 has a buffering effect on the reaction force borne by the guillotine 3.
[0039] Further, in this embodiment, a connecting seat 11 is provided on one side of the mounting seat 1, and the connecting seat 11 is connected to the milling cutter arm 8. This facilitates the connection between the mounting seat 1 and the connecting seat 11.
[0040] Furthermore, in this embodiment, the guillotine arm 8 is provided with a mounting hole 81 and a waist-shaped hole 82 for adjusting the mounting angle of the guillotine arm 8. The guillotine arm 8 cooperates with the external mounting shaft through the mounting hole 81, and is connected to the external mounting frame through the waist-shaped hole 82, and should be equipped with a locking piece for locking. The mounting angle can be adjusted by adjusting the locking position of the locking piece and the waist-shaped hole 82.
