Description

Technical Field

[0001] The utility model relates to the technical field of capping technology for aerosol cans, and particularly relates to a capping device. Background Art

[0002] An aerosol can is a disposable metal container for containing aerosol products (such as air fresheners, colorants for automotive paints, vehicle lubricants, or shoe and sock deodorants). When in use, the aerosol product is ejected through a valve and in a controlled form under a pre-pressure.

[0003] In the manufacturing of the above aerosol cans, there is a capping process. In the prior art, the lid is placed on the aerosol can during its transportation. After the lid is initially placed on the aerosol can, in the prior art, for example, an infrared sensing device is generally used to sense the position of the aerosol can. When the aerosol bottle is transported to the capping station, the aerosol bottles are first separated (fix the aerosol bottle at this station and block the subsequent aerosol bottles from moving forward), and then a cylinder is used to directly press down the lid with a cylinder pressing head, so as to complete the capping work in an orderly manner. However, during this capping process, the aerosol bottle remains stationary at the capping station before being capped, and the capping process is relatively slow. Therefore, this application proposes a capping device. Summary of the Utility Model

[0004] The utility model provides a capping device, which has a rotary feeding of a dartboard and is equipped with a fence, can maintain the stability of the aerosol can, and realize orderly feeding. During the feeding, the spiral transition surface of the pressing table can automatically press the lid onto the aerosol can through this spiral transition surface, and the capping efficiency is relatively high.

When the aerosol can rotates outside the dartboard, the lid is automatically pressed onto the aerosol can through this spiral transition surface.

[0009] Further, a number of notches are provided on the outer side of the dartboard, and the diameter of the notches is the same as the diameter of the aerosol can. When the aerosol can is located in the notch, the aerosol can can be prevented from tipping over.

[0010] Further, there are six groups of the notches, and the six groups of notches are distributed in an equidistant circular array.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] As shown in Figure 1 and Figure 2 An upper cover device in this embodiment is used to press a lid onto the aerosol can 1, and includes two groups of conveyors 2, one group of transition conveying structures 3, and one group of upper cover structures 4. The transition conveying structure 3 is arranged between the two groups of conveyors 2, that is, the two groups of conveyors 2 are distributed on the left and right sides of the transition conveying structure 3. The conveyor 2 on the left is used to convey the aerosol can 1 onto the transition conveying structure 3. The transition conveying structure 3 performs transfer conveying, and the upper cover structure 4 presses down the lid during the conveying process, so as to complete the lid covering of the aerosol can 1. The aerosol can 1 after lid covering is then sent out from the conveyor 2 on the right.

[0026] It should be noted that the conveyor 2 is, for example, a belt conveyor in the prior art for conveying materials, and will not be elaborated here.

[0027] As the focus of this application, the transition conveying structure 3 and the upper cover structure 4 will be described.

[0028] First, as shown in Figure 1-2 In order to receive the aerosol can 1 conveyed from the conveyor 2 on the left and enable the aerosol can 1 to be conveyed to the conveyor 2 on the right, the transition conveying structure 3 in this upper cover device includes a support table 31, a dartboard 32, a driving component, and two groups of enclosures 33. Among them, the driving component is arranged at the bottom of the support table 31. The dartboard 32 is rotatably arranged on the support table 31 and is assembled at the output end of the driving component. The enclosures 33 are fixed on the support table 31.

[0029] Furthermore, the driving component is a motor 34. The motor 34 is fixed to the bottom of the support table 31 by bolts. The center of the dartboard 32 has a rotating shaft 35. The output end of the motor 34 is connected to the dartboard 32 through the rotating shaft 35. In addition, a base 36 is arranged below the support table 31 and is erected on the ground. A plurality of support columns are fixed between the base 36 and the support table 31 to ensure the overall stability of the transition conveying structure 3.

[0030] It should be noted that the two sets of enclosures 33 are arc-shaped, coaxial with the dartboard 32 and the support platform 31. Moreover, the distance between the inner diameter of the enclosure 33 and the outer diameter of the dartboard 32 is preferably half of the diameter of the aerosol can 1. Additionally, several notches are provided on the outer side of the dartboard 32. The cross-section of the notch is semi-circular, and the diameter of the notch is the same as the diameter of the aerosol can 1. In this way, when the aerosol can 1 is located in the notch, the stability of the aerosol can 1 can be ensured, that is, the aerosol can 1 can be prevented from tipping over. As a preferred solution for the notch, there are six groups of notches, and the six groups of notches are evenly distributed in a circumferential array to maintain a constant feeding speed.

[0031] And it should also be noted that, as Figure 3-4 shown, there are openings on the left and right sides of the support platform 31. The two groups of openings are used to accommodate the conveyor 2, and the upper surface of the conveyor 2 is flush with the upper surface of the support platform 31. And the upper cover device further includes a guiding strip 5. The guiding strip 5 is welded on the support platform 31. It is located between the dartboard 32 and the enclosure 33 and is used to guide the discharged aerosol can 1 after being covered, so that the aerosol can 1 after being covered can move onto the conveyor 2 on the right side.

[0032] Secondly, in order to automatically and stably cover the aerosol can 1 during the transportation of the transition conveying structure 3, as Figure 1-2 shown, the covering structure 4 in the upper cover device includes a lifting component and a pressing platform 41. Among them, the lifting component is arranged on any one of the enclosures 33, and the pressing platform 41 is arranged to be liftable at the lifting end of the lifting component. A spiral transition surface is provided on the lower surface of the pressing platform 41, so that the thickness of the lower surface of the pressing platform 41 gradually changes from thin to thick. When the aerosol can 1 rotates outside the dartboard 32, the lid is automatically pressed down onto the aerosol can 1 through this spiral transition surface.

[0033] As a preferred solution for the lifting component in this embodiment, as Figure 1-2 shown, the lifting component includes a bracket 42. A fixed seat 43 is fixed on the bracket 42. A telescopic member 44 is fixedly arranged on the fixed seat 43 through bolts, and the pressing platform 41 is fixedly arranged at the telescopic end of the telescopic member 44.

[0034] Furthermore, the telescopic member 44 is one of a cylinder, an electric push rod or a hydraulic push rod. Utilizing the telescopic characteristics of the telescopic member 44, the height position of the pressing platform 41 can be changed. In this way, the covering operation of aerosol cans 1 with different heights can be adapted, and the adaptability of this upper cover device can be improved.

[0035] Working principle:

[0036] First, the conveyor 2 on the left transports the aerosol cans 1 that have not been pressed and covered to the transition conveying structure 3;

[0037] When the aerosol can 1 with the upper cover not pressed down is conveyed to any notch, due to the continuous driving of the dart board 32 by the motor 34, the aerosol can 1 will rotate around the dart board 32 and be restricted by the spiral transition surface of the pressing table 41 during rotation. The lid is automatically pressed onto the aerosol can 1 through this spiral transition surface;

[0038] Finally, when the aerosol can 1 with the upper cover is displaced to the conveyor 2 on the right, the conveyor 2 on the right will continue to convey the aerosol can 1 with the upper cover to the subsequent processing point. And during this process, when the aerosol can 1 rotates following the dart board 32 and is covered with the upper cover, the subsequent aerosol cans 1 can enter the next notch and follow the previous aerosol cans 1 for transfer and covering. In this way, orderly feeding is achieved and the covering efficiency is relatively high.

[0039] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
