[0002] A packaging machine is a device used to package products into final sales units. Packaging machines are mainly used in the packaging process of products in various fields such as food, medicine, cosmetics, and daily necessities. They can automatically complete a series of packaging operations such as product metering, dispensing, filling, sealing, and marking to improve packaging efficiency and quality.

[0003] The gas supply system of the packaging machine refers to the system used to provide the gas required for the normal operation of the packaging machine. The packaging machine usually needs to use compressed air as a power source. The existing air compression equipment cannot achieve high-efficiency compressed air supply.

[0004] In the packaging machinery industry, the air supply system plays a vital role. This system is specifically responsible for providing the packaging machine with the necessary gas for normal operation, ensuring the stable operation and production efficiency of the machinery. In many application scenarios, compressed air is widely used as a power source for packaging machines. However, the existing air compression equipment still has some shortcomings in efficiency and performance, and the existing air compression equipment has obvious shortcomings in compression efficiency. Traditional air compressors usually adopt piston or screw designs. Although these designs are relatively mature in technology, their compression efficiency is often severely limited when facing high-load work. In addition, due to reasons such as equipment aging and improper maintenance, the performance of traditional compressors decays rapidly, further affecting the stability and reliability of the air supply system.

[0005] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop an air supply system for a packaging machine. Utility Model Content

DETAILED DESCRIPTION

[0019] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0020] like Figure 1 , Figure 2 As shown, the utility model provides a technical solution of the air supply system of a packaging machine: comprising a casing 1, an end plate 11 is arranged at the front end of the casing 1, a compression assembly is installed on the end plate 11, the compression assembly comprises a mounting frame 21, a motor 22 is arranged on the mounting frame 21, a pulley 23 is arranged at the output end of the motor 22, a power wheel 24 is arranged on the adjacent side of the pulley 23, a belt 25 is arranged between the power wheel 24 and the pulley 23, the power wheel 24 is connected to a main gear 241 through a connecting shaft, a sub-gear 26 is arranged on the adjacent side of the main gear 241, and the main gear 2 41 is meshed with the sub-gear 26, a shell 29 is arranged outside the main gear 241 and the sub-gear 26, and the shell 29 is connected to the end plate 11, and the main gear 241 and the sub-gear 26 are respectively connected with a compression roller 1 27 and a compression roller 28, and the compression roller 1 27 and the compression roller 28 are located in the casing 1, and the compression roller 1 27 and the compression roller 28 are spirally provided with grooves and convex columns, and are engaged with each other, and a gas valve assembly 12 is arranged at the rear of the casing 1, and the gas valve assembly 12 is used to control the flow and pressure of the gas to realize the on-off and regulation of the gas path.

[0021] According to the above scheme, in this embodiment, when in use, the motor 22 is started, and the motor 22 drives the power wheel 24 to rotate through the pulley 23 and the belt 25. The power wheel 24 transmits the rotational power to the main gear 241 through the connecting shaft, and the main gear 241 is meshed with the sub-gear 26, thereby driving the sub-gear 26 and the compression roller 2 28 to rotate. The main gear 241 and the sub-gear 26 rotate in opposite directions, but due to the meshing connection of the grooves and the protrusions on the compression roller 1 27 and the compression roller 2 28 on them, the two can rotate synchronously, forming a continuous compression process.

[0022] When air enters through the housing 1, it is first guided and compressed by the spiral structure of the compression roller 1 27 and the compression roller 2 28. Due to the bite design of the groove and the convex column, the air can form a more uniform compressed airflow during the compression process, effectively improving the quality and stability of the compressed gas.

[0023] The compressed gas then enters the gas valve assembly 12 at the rear of the housing 1. The gas valve assembly 12 can accurately control the flow and pressure of the gas to achieve the on / off and regulation of the gas path. The user can set the required gas pressure and flow by adjusting the gas valve assembly 12 according to actual needs.

[0024] The packaging machine air supply system of the utility model realizes efficient and stable gas compression and regulation functions through its unique compression component and air valve component design. Compared with traditional piston or screw compressors, the utility model has the advantages of simple structure, high compression efficiency, good stability, easy maintenance, etc., and can be widely used in various packaging machines.

[0025] In addition, since the compression assembly of the utility model adopts a spiral structure of grooves and convex pillars, the air can form a more uniform compressed airflow during the compression process, thereby improving the quality and stability of the compressed gas. This innovative design not only improves the performance of the packaging machine, but also provides strong support for the rapid development of the packaging industry.

[0026] In summary, the packaging machine air supply system provided by the utility model realizes efficient and stable gas compression and regulation functions through its unique compression component and air valve component design, providing strong support for the rapid development of the packaging industry.

[0027] like Figure 1 , Figure 2 As shown, a tensioning assembly is arranged on the outside of the belt 25, and the tensioning assembly includes a tensioning frame 31, and the tensioning frame 31 is connected to the end plate 11. A tensioning wheel 32 is arranged on the tensioning frame 31, and the tensioning wheel 32 abuts against the belt 25. A fixing column 33 is arranged on the end plate 11 adjacent to one side of the tensioning frame 31, and the fixing column 33 is connected to the tensioning frame 31 through a traction spring 34.

[0028] According to the above scheme, in this embodiment, when in use, the tensioning assembly is firmly connected to the end plate 11 through the tensioning frame 31, ensuring the position stability of the tensioning wheel 32. The tensioning wheel 32 is in close contact with the belt 25. When the belt 25 is affected by tension during operation, the tensioning wheel 32 will make corresponding adjustments according to the tension of the belt. If the belt 25 is loose, the tensioning wheel 32 will apply pressure to the belt 25 under the action of the traction spring 34 to tension it; when the tension of the belt 25 is too large, the tensioning wheel 32 will retreat slightly under the pulling force of the belt 25, and the excessive tension of the belt will be avoided through the buffering effect of the traction spring 34.

[0029] The fixing column 33 is arranged on the end plate 11 adjacent to the tensioning frame 31, and is connected to the tensioning frame 31 through a traction spring 34. The design of the traction spring 34 allows the tensioning wheel 32 to move freely within a certain range to adapt to the tension change of the belt 25. This design not only ensures the stable operation of the belt 25, but also prolongs the service life of the belt.

[0030] In summary, the tensioning assembly in this embodiment has a reasonable design, a simple structure, and is easy to operate. It can effectively ensure the stability and reliability of the belt transmission and improve the use efficiency and life of the equipment.
