Technical Field

[0001] This utility model relates to the field of aerosol packaging technology, and is a sealing mechanism for aerosol cans. Background Technology

[0002] Currently, the market offers a wide variety of aerosol product sealing equipment, ranging from simple manual operation to highly automated production lines. However, despite advancements in versatility and functionality, existing equipment still needs improvement in sealing quality and efficiency to meet the specific needs of aerosol cans. Traditional sealing methods often employ single pressure application or fixed operating patterns, which can easily lead to can opening deformation or cap breakage, thus affecting the product's sealing performance and safety. These problems are particularly pronounced in large-scale production, increasing defect rates and potentially threatening consumer experience and safety. Therefore, a new aerosol can sealing mechanism needs to be developed to improve sealing quality, production efficiency, and equipment applicability. This new mechanism needs to possess greater flexibility and adaptability, automatically adjusting sealing parameters according to different can sizes and materials to ensure a stable and reliable sealing process.

The spring design allows for some elastic compensation during the sealing process, adapting to can openings of different sizes and shapes, ensuring a tight and consistent seal.

[0013] 2. Enhanced equipment flexibility and adaptability: The design of springs and grooves allows the sealing body to slide up and down within a certain range, which increases the self-adaptability during the sealing process. It can better cope with aerosol cans of different specifications and materials on the production line, and improve the equipment's versatility and applicability.

[0014] 3. Improved production efficiency: The sealing positioning block ensures accurate positioning during each sealing operation, reducing the defect rate caused by positional deviations. Simultaneously, the automated sealing process significantly increases production speed and reduces labor costs.

[0015] 4. Optimized Structural Design: The second spring design at the bottom of the elastic claw head, and its rotating connection with the sealing body, allow the elastic claw head to tighten and spring back according to the size of the can opening during the sealing process, ensuring the uniformity and reliability of the seal. Furthermore, the use of tightening screws in conjunction with threaded holes and notches not only simplifies the installation and maintenance process but also enhances the connection strength between the sealing head and the connecting seat, extending the service life of the equipment.

[0016] In summary, this aerosol can sealing mechanism, through its lifting cylinder and spring design, precisely controls the sealing pressure and provides elastic compensation, preventing can opening deformation or cap damage, thus improving sealing quality and consistency. The spring and sliding groove allow the sealing body to slide up and down, enhancing adaptability to cans of different sizes. The sealing positioning block ensures accurate positioning, reducing the defect rate, and the automated process improves production efficiency. Optimized structural design, such as the second spring and rotating connection of the elastic claw head, and the use of tightening screws, simplifies installation and maintenance, strengthens component connections, and extends equipment life.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4A sealing mechanism for an aerosol can includes a lifting cylinder 1, a sealing head 2 driven at the bottom of the lifting cylinder 1, a connecting seat 3 at the bottom of the sealing head 2, a sealing body 4 slidably disposed at the bottom of the connecting seat 3, a spring 5 disposed between the connecting seat 3 and the sealing body 4, a plurality of elastic claws 6 disposed at the bottom of the sealing body 4, the upper end of the connecting seat 3 disposed inside the sealing head 2, the sealing head 2 being fixed to the connecting seat 3 by tightening screws 7, a sliding groove 8 disposed inside the connecting seat 3, the top of the sealing body 4 being slidably disposed within the sliding groove 8, and a sealing positioning block 9 disposed at the bottom of the sealing body 4.

[0024] The bottom of the connecting seat 3 is provided with a first groove 10, the upper part of the sealing body 4 is provided with a second groove 11, a cavity 12 is provided between the connecting seat 3 and the sealing body 4, one end of the spring 5 is provided in the first groove 10, the other end of the spring 5 is provided in the second groove 11, and the spring 5 is located in the cavity 12.

[0025] A second spring 13 is provided at the bottom of the elastic claw head 6. When the connecting seat 3 slides down, it drives the elastic claw head 6.

[0026] The upper part of the sealing body 4 is provided with multiple fasteners 41, and the elastic claw head 6 is rotatably connected to the sealing body 4 through the fasteners 41.

[0027] The sealing head 2 is provided with a threaded hole 21, and the connecting seat 3 is provided with a notch 31. The tightening screw 7 is threadedly connected to the threaded hole 21, and the tightening screw 7 passes through the sealing head 2 into the notch 31.

[0028] A sealing ring 14 is provided at the bottom of the sealing positioning block.

[0029] In this embodiment, firstly, when an unsealed aerosol can is transported to the sealing station, the control system triggers the lifting cylinder 1 to move downwards. As the cylinder descends, it moves the sealing head 2, which is connected to its bottom, downwards along with it. A connecting seat 3 is housed inside the sealing head 2, and the connecting seat 3 is connected to the sealing body 4 via a sliding groove 8, allowing the sealing body 4 to slide up and down within a certain range. This provides additional flexibility to accommodate can openings of different heights or shapes.

[0030] At the bottom of the sealing body 4, there are multiple elastic claws 6. When these claws apply downward pressure through the mechanism, they clamp the mouth of the agent can as the connecting seat 3 slides downward. Each elastic claw 6 is equipped with a second spring 13, which can spring back. At the same time, the elastic claws 6 are rotatably connected to the sealing body 4 through the fixing member 41, which further enhances the adaptability.

[0031] A spring 5 is installed in the cavity 12 between the connecting seat 3 and the sealing body 4. One end of the spring is located in the first groove 10 at the bottom of the connecting seat 3, and the other end is located in the second groove 11 at the top of the sealing body 4. When the sealing operation begins, the connecting seat 3 slides downward to compress the spring 5. This not only helps to maintain the stability of the sealing pressure, but also allows for a certain degree of elastic compensation to avoid excessive pressure causing deformation of the can opening.

[0032] To ensure that the sealing positioning block 9 can be accurately aligned with the aerosol can opening, a sealing ring 14 is fitted to its bottom to enhance sealing performance. In addition, the threaded hole 21 on the sealing head 2 mates with the notch 31 on the connecting seat 3, and the two are firmly joined together by tightening the screw 7 to ensure that the entire sealing device will not loosen during operation.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
