DETAILED DESCRIPTION

[0040] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0041] The specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0042] Example 1

[0043] In this embodiment, a bottle cap logo printing device is proposed. Figure 1-Figure 10 The bottle cap mark printing device includes a second driving member 4, a positioning sleeve 23 fixedly combined with the non-driving portion of the second driving member 4, and a swivel sleeve 25 that snares the positioning sleeve 23 and rotatably cooperates with the positioning sleeve 23.

[0044] For further instructions, see Figure 7-Figure 9 The top of the positioning sleeve 23 extends upward to the first extension portion 10 of the positioning sleeve of the non-driving part of the second driving member 4. In addition, the junction between the first extension portion 10 of the positioning sleeve and the positioning sleeve 23 is the outwardly expanded second extension portion 14 of the positioning sleeve.

[0045] Please continue reading Figure 7-Figure 9 Regarding the rotary sleeve 25, its top opening is the outwardly expanded rotary sleeve first extension portion 24, and its bottom opening is the outwardly expanded rotary sleeve second extension portion 17. It should be particularly noted that the outward expansion radius of the positioning sleeve second extension portion 14 is greater than the outward expansion radius of the rotary sleeve first extension portion 24.

[0046] See also Figure 5-Figure 8 The outer peripheral wall of the second extension part 17 of the rotary sleeve is surrounded by a plurality of cover pressing rods 16 (the outer peripheral wall of the second extension part 17 of the rotary sleeve is provided with a plurality of rod grooves 26 for limiting the movement of the cover pressing rods 16). For the cover pressing rods 16, from top to bottom, they are respectively a first rod elastically matched with the first extension part 24 of the rotary sleeve, a bent portion always located above the second extension part 17 of the rotary sleeve, and a second rod restricted by the movement of the second extension part 17 of the rotary sleeve and extending downward relative to the bottom of the second extension part 17 of the rotary sleeve.

[0047] See also Figure 5-Figure 7 A plurality of slide grooves 13 are arrayed around the corners of the first extension portion 10 of the positioning sleeve and the second extension portion 14 of the positioning sleeve, wherein a slider 12 is adapted in each slide groove 13, and the slider 12 has an elastic sliding fit with the corresponding slide groove 13.

[0048] It should be emphasized that, in this embodiment, a plurality of wheel frames 11 need to be provided in combination with the number of capping rods 16 that cannot be inserted into the arc-shaped groove of the bottle cap.

[0049] To further illustrate, when all the capping rods 16 move into the top of the bottle cap and contact the top of the bottle cap when the positioning sleeve 23 presses into the top of the bottle cap, there are two states:

[0050] ① Part of the capping rod 16 enters the arc groove on the top of the bottle cap (the depth of the arc groove is greater than the amount of the capping rod 16 extending downward relative to the second extension portion 17 of the rotary sleeve), and the part of the capping rod 16 does not move;

[0051] ② The remaining capping rod 16 pushes the top cover of the bottle cap, thereby moving upward relative to the second extension portion 17 of the rotary sleeve with the top of the bottle cap as a solid bottom.

[0052] In combination with the above description, the core of this embodiment is as follows:

[0053] ①Perception Figure 1 The angle difference between the marked area and the engraved area shown; ② Correction Figure 1The angle difference between the marking area and the engraved area is shown.

[0054] In order to achieve the above core goal, the above-mentioned multiple wheel frames 11 are continuously fixedly combined with multiple sliders 12. To further explain, each wheel frame 11 passes through the second extension portion 14 of the positioning sleeve and extends downward to the curved portion of the cover pressing rod 16. In addition, the downward extending portion of the slider 12 is equipped with a rotating wheel 21 that has a height difference with the curved portion of the cover pressing rod 16.

[0055] See also Figure 4 The bottle cap marking printing device also includes a motor 5 for driving the rotary sleeve 25 to rotate axially around the positioning sleeve 23. When the positioning sleeve 23 is closed on the top of the bottle cap, the motor 5 first needs to combine whether all the capping rods 16 that are not inserted into the arc groove of the bottle cap lift up all the pre-set wheel frames 11 to judge the angle difference between the bottle cap marking area and the engraving area, that is, as long as one of all the wheel frames 11 is not lifted up, the bottle cap marking area and the engraving area are deviated. On the contrary, when all the wheel frames 11 are lifted up, the bottle cap marking area and the engraving area are aligned and overlapped.

[0056] In combination with the above settings, the motor 5 drives the rotary sleeve 25 to rotate, and based on the rolling contact between the curved portion of the capping rod 16 and the rotating wheel 21, the combination of all the wheel frames 11 and the rotating wheel 21 is lifted to adjust the angle difference between the bottle cap marking area and the printing area.

[0057] Further, when all the combinations of the wheel frames 11 and the rotating wheels 21 are lifted up, the motor 5 is powered off. In addition, in this embodiment, there is a printing plate 22 located in the positioning sleeve 23 and pressed down or pulled up by the second driving member 4, wherein the bottom of the printing plate 22 is provided with a marking area, and the center line of the marking area coincides with the center line of the plurality of wheel frames 11. In this way, the second driving member 4 is powered on after the motor 5 driving the rotating sleeve 25 is powered off, and then combined with Figure 7 The push rod 9 shown drives the printing plate 22 to press the bottle cap marking area downward.

[0058] For details, please refer to Figure 6-Figure 9 A limit rod 20 is provided in the slide groove 13 for guiding the slider 12 to slide up and down, a second spring 19 is trapped at the limit rod 20 for pulling the slider 12 to slide downward, and there are induction sheets 18 corresponding to multiple wheel frames 11 one by one, wherein the induction sheets 18 are inserted into the slide groove 13, and the induction sheets 18 are located in the sliding path of the slider 12. Accordingly, when all the capping rods 16 that have not been inserted into the arc groove of the bottle cap lift up the combinations of all the wheel frames 11 and the rotating wheel 21 one by one, the slider 12 contacts all the induction sheets 18, so that the second driving member 4 is powered.

As for the motor 5, it is equipped with a roller 8, which has a frictional rolling contact with the outer surface of the second extension 17 of the rotary sleeve, and is used to drive the rotary sleeve 25 to rotate axially around the positioning sleeve 23 based on the roller 8 after the motor 5 is powered on.

[0061] ② The bottle cap mark printing device also includes a first driving member 1 for driving the positioning sleeve 23 to cover the bottle cap, and a sleeve 2 that frames the outer shell 6 and is fixedly combined with the outer shell 6. The sleeve 2 is provided with a partition 3, and the partition 3 is fixedly combined with the first driving member 1, so that when the first driving member 1 presses down or pulls up the sleeve 2, the outer shell 6 moves synchronously.

[0062] ③ A plurality of first springs 15 corresponding to the cover pressing rods 16 are arranged in an array around the bottom of the first extension portion 24 of the rotary sleeve, wherein one end of the cover pressing rod 16 is fixedly combined with the first extension portion 24 of the rotary sleeve, and the other end of the cover pressing rod 16 is fixedly combined with the first rod in the cover pressing rod 16.
