Technical Field

[0001] The utility model relates to the technical field of bottle cap production, in particular to a device for positioning and pressing a light shielding sheet in a bottle cap. Background Art

[0002] The bottle cap of bottled liquor includes two parts, the first part is used to be installed on the mouth of the wine bottle, and the second part is used to be screwed and installed on the first part, so as to close the mouth of the wine bottle. The second part includes an outer cover 8 and an inner cover, and the inner cover is installed in the open mouth of the outer cover 8. At present, the inner cover is generally made of transparent plastic material, and a two-dimensional code is sprayed on the top wall of the inner cover. In order to prevent the internal environment of the outer cover 8 from affecting the scanning and recognition of the two-dimensional code, a white light-shielding sheet 7 is installed inside the outer cover 8 and on the top of the inner cover, so as to facilitate the scanning and recognition of the two-dimensional code. At present, the light-shielding sheet is installed in the outer cover 8 by manual placement, and the production efficiency is low. Therefore, the inventor designs a positioning and pressing device for the light-shielding sheet in the bottle cap.

The height of the positioning ring 2 is limited by the cooperation between the annular groove 21 and the flange 12, and the height of the space for placing the shading sheet 7 is also controlled. The outer cover 8 is limited by the annular wall 23. When in use, the outer cover 8 is sleeved on the outside of the annular wall 23, and the annular wall 23 cooperates with the inner wall of the outer cover 8. The lower end of the outer cover 8 rests on the annular platform 22, so that the shading sheet can be conveniently and accurately installed inside the outer cover.

[0024] When in use, the base 6 can be a part of the pressing device of the present application or a part of other equipment, and the positioning column 1 can be installed on the base 6 by using the threaded connection method in CN202045482U.

[0025] Since the positioning column 1 is a cylindrical structure, it is not convenient to install and tighten the positioning column 1 directly by screwing it onto the base 6. Figure 1-5 A countersunk hole 11 is axially provided inside the positioning column 1, and the screw 3 is inserted into the countersunk hole 11 and then screwed with the threaded hole on the base 6. The positioning column 1 is installed and fixed by the screw 3, and the installation is convenient. Specifically, the screw 3 is a hexagon socket screw.

[0026] For further information, see Figure 1 The outer wall of the lower end of the positioning ring 2 is also provided with a first limiting groove 24, and the upper end of the first spring 4 is sleeved on the first limiting groove 24, so as to limit the upper end of the first spring 4.

[0027] Furthermore, a limiting ring 5 is also mounted on the lower end of the positioning column 1 , and a second limiting groove 51 is provided on the upper outer wall of the limiting ring 5 . The lower end of the first spring 4 is mounted on the second limiting groove 51 , thereby limiting the lower end of the first spring 4 .

[0028] Furthermore, a boss 52 is provided on the inner wall of the lower end of the limiting ring 5 , and a groove cooperating with the boss 52 is provided on the outer wall of the lower end of the positioning column 1 . The groove at the lower end of the positioning column 1 cooperates with the boss 52 to fix the position of the limiting ring 5 .

[0029] See also Figure 1 In order to facilitate the outer cover 8 to be inserted outside the annular wall 23, an outer chamfer 25 is provided on the top of the annular wall 23. The outer chamfer 25 can be an oblique angle or a circular angle.

[0030] See also Figure 5 The positioning column 1 is composed of two parts, an upper part and an lower part, and a second spring 15 is installed between the upper and lower parts of the positioning column 1. The above structure prevents the outer cover 8 from being excessively pressed down during the pressing process, causing the positioning column 1 to break the installation position for installing the light shielding sheet 7 inside the outer cover 8, thereby causing the outer cover 8 to be scrapped. In this way, the precision requirement of the pressing distance of the outer cover 8 can be reduced.

[0031] Furthermore, the first guide ring 13 and the second guide ring 14 are respectively provided at opposite ends of the upper and lower parts of the positioning column 1, and the second guide ring 14 can be slidably mounted on the outside of the first guide ring 13, or can be slidably inserted into the inside of the first guide ring 13. The sliding fit between the first guide ring 13 and the second guide ring 14 plays a role in guiding and improving the accuracy, thereby preventing the upper part of the positioning column 1 from shaking when sliding up and down.

[0032] It should be noted that when the positioning column 1 consists of two parts, the height of the entire device is adjusted by the length of the screw 3, the screw 3 is tightened with the base 6 to fix the entire device, and the upper part of the positioning column 1 slides with the screw 3, and at the same time, the countersunk depth of the center countersunk hole 11 of the positioning column 1 is greater than the height of the screw tightening head.

[0033] In addition, the second guide ring 14 can be slidably mounted on the outside of the first guide ring 13, or can be slidably inserted into the inside of the first guide ring 13, that is, when the second guide ring 14 can be slidably mounted on the outside of the first guide ring 13, the second guide ring 14 is outside and the first guide ring 13 is inside; when the second guide ring 14 can be slidably inserted into the inside of the first guide ring 13, the second guide ring 14 is inside and the first guide ring 13 is outside. Figure 5 At this time, the second guide ring 14 is inside and the first guide ring 13 is outside.

[0034] The action process or principle of the utility model is as follows:

[0035] When in use, the outer cover 8 can be pressed manually, or the device in CN202045482U can be used to press the outer cover 8.

[0036] When placing the shading sheet 7, refer to Figure 1 The first spring 4 elastically supports the positioning ring 2 , the cooperation between the ring groove 21 and the flange 12 limits the height of the positioning ring 2 , and a space for placing the shading sheet 7 is formed inside the ring wall 23 .

[0037] See also Figure 2 First, place the shading sheet 7 on the top of the positioning column 1 in the internal space of the annular wall 23, and then put the outer cover 8 on the outside of the annular wall 23. The annular wall 23 cooperates with the inner wall of the outer cover 8 and is centered. The lower end of the outer cover 8 rests on the annular platform 22.

[0038] See also Figure 3 , the outer cover 8 is pressed down, the positioning ring 2 moves down, the first spring 4 is compressed, the top of the positioning column 1 extends upward, and the shading sheet 7 is sent to the shading sheet installation position in the outer cover 8. When the outer cover 8 is further pressed down, the shading sheet 7 is completely installed in place. If the outer cover 8 is excessively pressed down, at this time, the upper part of the positioning column 1 is pressed down, and the second spring 15 is compressed, thereby preventing the installation position for installing the shading sheet 7 inside the outer cover 8 from being damaged.

[0039] See also Figure 4 , then lift the outer cover 8, the first spring 4 and the second spring 15 are reset, and the next shading sheet 7 can be installed.
