DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0027] See also Figure 1-5 As shown, a bottle cap sterilizing device includes a first main body 1 with a first cavity, a carrying plate 2 rotatable around its own axis and arranged in the first main body 1 for carrying the end face of the bottle cap 3, a cover plate 4 fixed in the first main body 1 and located above the carrying plate 2, and a guide channel 5 extending along a plane spiral direction and arranged on the lower surface of the cover plate 4 for guiding the bottle cap 3.

[0028] See also Figure 5As shown, the bottle cap sterilizing device further includes a sleeve 9 disposed in the first body 1, a rotating shaft 10 disposed in the sleeve 9 and rotatable about its own axis, and a carrier plate 2 fixedly connected to the top of the rotating shaft 10. The rotation of the rotating shaft 10 drives the carrier plate 2 to rotate. In this embodiment, the sleeve 9, the rotating shaft 10, and the carrier plate 2 have the same axis.

[0029] See also Figure 4-5 As shown, the bottle cap sterilizing device further includes a plurality of support columns 11 disposed in the first body 1 and arranged at intervals around the outside of the carrier plate 2. The support columns 11 are fixedly connected to the cover plate 4. The support columns 11 are arranged at intervals around the carrier plate 2, and the top ends of the support columns 11 are higher than the carrier plate 2.

[0030] See also Figure 5 As shown, the bottle caps 3 on the carrier plate 2 are horizontal, with their end faces facing downwards, forming surface contact with the upper surface of the carrier plate 2, and their openings facing upwards, and spaced apart from the cover plate 4 in the vertical direction.

[0031] The guide channel 5 extends in a spiral direction within a plane and includes two spirally extending guide side plates 51 . The two guide side plates 51 are located on both sides of the bottle cap 3 and are used to guide the bottle cap 3 when the supporting plate 2 rotates.

[0032] In this embodiment, the axis of the carrier plate 2 is along the vertical direction (ie Figure 5 The carrier plate 2 is used to guide the bottle caps 3 to be transported in a spiral direction in a horizontal plane through a spiral guide channel 5. The spiral center line of the guide channel 5 coincides with the axis of the carrier plate 2.

[0033] See also Figure 5 As shown, the guide side plates 51 and the carrier plate 2 are spaced apart in the vertical direction, and the distance between the bottom end of the guide side plates 51 and the carrier plate 2 is less than the height of the bottle caps 3. This arrangement not only prevents friction between the bottom end of the guide side plates 51 and the upper surface of the carrier plate 2, but also reduces the friction area between the guide side plates 51 and the bottle caps 3, thereby reducing the friction force between the guide side plates 51 and the bottle caps 3. When the carrier plate 2 rotates, the bottle caps 3 can be smoothly conveyed in a spiral direction along the guide channel 5 due to the friction between their end surfaces and the carrier plate 2.

[0034] The bottle cap 3 is transferred in a spiral direction in a plane by the friction between the end surface of the bottle cap 3 and the supporting plate 2 , and the bottle cap 3 is guided by the guide channel 5 , so as to avoid deformation of the bottle cap 3 due to stress.

[0035] See also Figure 1As shown, the above-mentioned bottle cap sterilization device also includes a second body 6 having a second cavity and connected to the first body 1, a cap outlet guide rail assembly 7 arranged in the second body 6, and a cap inlet guide rail assembly 8 passing through the first body 1. The cap inlet guide rail assembly 8 and the cap outlet guide rail assembly 7 are respectively connected to the spiral inner end portion and the spiral outer end portion of the guide channel 5.

[0036] See also Figure 2 As shown, the first body 1 and the second body 6 are arranged in sequence from right to left. A first opening is provided on the upper surface of the first body 1, and the cap inlet guide rail assembly 8 passes through the first opening and is connected with the spiral inner end of the guide channel 5, so as to feed the bottle cap 3 into the guide channel 5; a second opening is provided at the left end of the second body 6, and the left end of the cap outlet guide rail passes through the second opening, and the cap outlet guide rail is connected with the spiral outer end of the guide channel 5 through its right end.

[0037] See also Figure 3 As shown, when the carrying plate 2 rotates clockwise, it is used to send the bottle caps 3 entering from the inner end of the guide channel 5 out through the outer end of the guide channel 5.

[0038] See also Figure 2-4 As shown, the cap discharging guide rail assembly 7 includes a flip section 16 and a straight section 17, which are sequentially connected in a direction away from the guide channel 5. In this embodiment, the flip section 16 is connected to the outer end of the guide channel 5 and is located in the first body 1. The straight section 17 is connected to the flip section 16 and is entirely located in the second body 6, with the right end of the straight section 17 located in the first body 1. The provision of the flip section 16 is used to flip the bottle caps 3 from a horizontal position to a vertical position. Since the bottle caps 3 on the carrier plate 2 are in a horizontal position, they are flipped from a horizontal position to a vertical position in the second body 6 to facilitate the conveyance of the bottle caps 3, allowing the bottle caps 3 to roll along the output direction via their outer circumferential surface in the straight section 17.

[0039] See also Figure 2-5 As shown, the bottle cap sterilizing device further includes a spraying mechanism disposed in the first body 1 and used for spraying disinfectant onto the bottle cap 3 .

[0040] In this embodiment, the spray mechanism includes a first spray pipe 12 disposed above the cover plate 4 and configured to spray disinfectant downward, and a second spray pipe 13 disposed below the carrier plate 2 and configured to spray disinfectant upward. The bottle cap sterilizing device further includes a first through hole 14 formed on the cover plate 4 and located below the first spray pipe 12, and a second through hole 15 formed on the carrier plate 2 and located above the second spray pipe 13.

[0041] See also Figure 4As shown, the first through hole 14 is an arc-shaped elongated hole, while the second through hole 15 is a small hole. The arc-shaped elongated hole ensures that the disinfectant sprayed from the first spray pipe 12 can be sprayed unimpeded and always reaches the surface of the bottle cap 3. The small hole ensures that the disinfectant sprayed from the second spray pipe 13 can be sprayed onto the surface of the bottle cap 3 while also preventing the bottle cap 3 from falling off the carrier plate 2 during transportation.

[0042] See also Figure 4 As shown, the first spray pipe 12 and the second spray pipe 13 are arc-shaped spray pipes along their own length extension direction, and their arc direction is the same as the spiral direction of the guide channel 5. In other words, the first spray pipe 12 is always located directly above the bottle cap 3, and the second spray pipe 13 is always located directly below the bottle cap 3. Through this arrangement, when the bottle cap 3 is conveyed in the guide channel 5 in the spiral direction, it can be continuously sprayed with disinfectant along a certain section or the entire conveying path, thereby achieving a good sterilization and disinfection effect.

[0043] See also Figure 4-5 As shown, a first guide tube 20 with an opening toward the bottle cap 3 is provided below the first spraying tube 12, and a second guide tube 21 with an opening toward the bottle cap 3 is provided above the second spraying tube 13. By providing the first guide tube 20 and the second guide tube 21, it is ensured that the disinfectant can be correctly sprayed onto the bottle cap 3.

[0044] In this embodiment, see Figure 5 As shown, the spray direction of the first spray pipe 12 is generally downward, and the spray direction of the second spray pipe 13 is generally upward, and they are respectively parallel to the axis of the guide channel 5, that is, perpendicular to the conveying direction of the bottle caps 3. In other words, the sprayed disinfectant is only used to disinfect and sterilize the bottle caps 3, and does not provide power for conveying the bottle caps 3. While ensuring the sterilization effect, the consumption of disinfectant is greatly reduced.

[0045] See also Figure 2-3 As shown, the bottle cap sterilizing device further includes a blowing mechanism disposed in the second cavity and used for blowing the bottle cap 3 .

[0046] In this embodiment, the blowing mechanism includes a blowing pipe 18 for blowing the bottle cap 3 to drive the bottle cap 3 to roll in the straight section 17. Figure 2 As shown, the blowing pipe 18 extends obliquely in the vertical direction, with its nozzle facing the inner side of the upright bottle cap 3. While blowing the bottle cap 3, the bottle cap 3 is rolled from right to left and finally output from the left end of the cap discharging track assembly.

[0047] See also Figure 2-4As shown, the cap feed guide rail assembly 8 includes a plurality of first guide bars 81 for cooperating to enclose the bottle caps 3, and a first flange 82 for circumferentially securing the plurality of first guide bars 81. The plurality of first guide bars 81 extend along the conveying direction of the bottle caps 3 and have a rectangular cross-section that matches the shape of the bottle caps 3, allowing the bottle caps 3 to roll therein. The plurality of first guide bars 81 are configured to contact at least the two end surfaces and radial sides of the outer circumference of the bottle caps 3. The first flange 82 is fixedly disposed around the outer sides of the plurality of first guide bars 81.

[0048] See also Figure 2-4 As shown, the cap discharging guide rail assembly 7 includes a plurality of second guide bars 71 that cooperate to enclose the bottle caps 3, and a second flange 72 for circumferentially securing the plurality of second guide bars 71. The plurality of second guide bars 71 extend along the conveying direction of the bottle caps 3 and have a rectangular cross-section that matches the shape of the bottle caps 3, allowing the bottle caps 3 to roll therein. The plurality of second guide bars 71 are configured to contact at least the two end surfaces and radial sides of the outer circumference of the bottle caps 3. The second flange 72 is fixedly disposed around the outer sides of the plurality of second guide bars 71.

[0049] See also Figure 1-3 As shown, the above-mentioned bottle cap sterilization device also includes a third body 19 having a third cavity. The third body 19 is connected to the first body 1 and the second body 6 respectively. The cap outlet guide rail assembly 7 passes through the third body 19 and is connected to the guide channel 5. In this embodiment, the straight segment 17 passes through the third body 19 and is connected to the guide channel 5.

[0050] The third body 19 is used to separate the first cavity and the second cavity through the third cavity. Since disinfectant is diffused in the first cavity and spray gas is diffused in the second cavity, in order to prevent a large amount of gas in the second cavity from entering the first cavity, thereby affecting the concentration of the disinfectant and the sterilization effect, the third body 19 is arranged between the first body 1 and the second body 6. A connecting channel with a significantly reduced cross-section is formed at the connection between the third body 19, the first body 1 and the second body 6, that is, the cross-section of the third body 19 is relatively small. It can effectively prevent the gas in the second cavity from entering the first cavity.

[0051] See also Figure 1-2 As shown, in this embodiment, an air extraction port 22 is provided on the first body 1, and the air extraction port 22 is located on the side of the first body 1 close to the third body 19. By providing the air extraction port 22, not only the vapor disinfectant diffused in the first body 1 can be extracted outward, but also the spray gas diffused from the second cavity into the first cavity can be extracted.

[0052] The working process of this embodiment is described in detail below:

[0053] The bottle caps 3 enter the carrying plate 2 from the cap inlet guide rail assembly 8 and are horizontally arranged on the carrying plate 2. The rotating shaft 10 drives the carrying plate 2 to rotate, so that the bottle caps 3 are conveyed in a spiral direction in the guide channel 5. During the conveying process, disinfectant is sprayed to the bottle caps 3 through the spraying mechanism. Then the bottle caps 3 enter the flip section 16 of the cap outlet guide rail assembly 7, and after being flipped to a vertical position, they enter the straight section 17 of the cap outlet guide rail assembly 7. During the conveying process, gas is sprayed to the bottle caps 3 through the blowing mechanism to avoid residual disinfectant. At the same time, the blown gas also provides power for the conveying of the bottle caps 3. Finally, the bottle caps 3 are output from the cap outlet guide rail assembly 7.
