[0041] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the driving member 11 and the heat-conducting component 12 are both arranged in the first shell 101 of the heat-sealing shell 10, and the driving member 11 is connected to the heat-conducting component 12.

[0042] The first housing 101 includes a first hollow plate 1012, a first panel 1013 and two opposite first side plates 1011. The first hollow plate 1012 is arranged at one end of the first housing 101. One ends of the two opposite first side plates 1011 are connected to the first hollow plate 1012, and one side of the two opposite first side plates 1011 is connected to the first panel 1013. Correspondingly, the second housing 102 includes a second panel 1023 and two opposite second side plates 1022. One side of the two second side plates 1022 is connected to the second panel 1023. The other sides of the two second side plates 1022 are respectively connected to the other sides of the two first side plates 1011 in a corresponding manner so as to be openable and closable. The other sides of the two second side plates 1022 are respectively connected to the other sides of the two first side plates 1011 to form two opposite side surfaces of the heat-sealed housing 10.

A rotating mechanism 103 is provided on one end of the second hollow plate 1024 away from the second panel 1023, and the second shell 102 is openably connected to the first shell 101 through the rotating mechanism 103. The rotating mechanism 103 includes a rotating fixed portion 1031 and a rotating movable portion 1032, the rotating fixed portion 1031 is connected to the first panel 1013, and the two sides of the rotating movable portion 1032 are respectively connected to the rotating fixed portion 1031 and the second hollow plate 1024, and a second air distribution block 15 is provided on the second hollow plate 1024. At least one heat dissipation hole (not marked in the figure) is provided on the second panel 1023, and the heat dissipation hole is provided below the heat sealing portion 1021, and the second air distribution hole on the second air distribution block 15 is connected to the heat dissipation hole. The second air distribution block 15 can effectively distribute the cold air introduced into the heat sealing device 100 for packaging equipment to the inside of the heat sealing device 100 for packaging equipment when the heat sealing device 100 is cooled. An air outlet plate baffle (not marked in the figure) is also provided on the rear side of the second hollow plate 1024 away from the first hollow plate 1012. The air outlet plate baffle can effectively prevent the hot air generated by the internal heat conduction component 12 from escaping when it is heated, thereby effectively avoiding the problem of large heat sealing temperature changes and poor hot air effect caused by the escaping of hot air.

[0044] In some embodiments of the present invention, the driving member 11 is preferably a slide cylinder. A heat insulating member 13 is also provided between the driving member 11 and the heat conducting component 12. The heat insulating member 13 is fixedly connected to the movable part of the driving member 11, and the heat insulating member 13 can move relative to the heat sealing shell 10 under the drive of the driving member 11. A first air dividing block 14 is also installed in the first shell 101. The first air dividing block 14 is arranged on the side of the heat insulating member 13 close to the driving member 11, and the first air dividing block 14 is closely connected to the driving member 11. One side of the first air dividing block 14 is arranged against one of the first side plates 1011, and the heat insulating member 13 is arranged on the other side of the first air dividing block 14, and a cushion block (not shown) is installed between the first air dividing block 14 and the heat insulating member 13.

A wire transition block 16 is also installed in the first shell 101, and the wire transition block 16 is close to one end of the heat-conducting component 12 away from the first hollow plate 1012. The heat-conducting component 12 completes the arrangement of the electrical connection wires (not shown) of the heat-conducting component 12 in the first shell 101 through the wire transition block 16. The electrical connection wires of the heat-conducting component 12 pass through the wire connection holes of one of the first side plates 1011 of the first shell 101 to achieve electrical connection with the external power supply.

[0046] Specifically, the driving member 11 works to push the heat insulating member 13 to move, and the heat insulating member 13 drives the heat conducting pipe 121 to move. The interior of the heat conducting pipe 121 is a hollow structure and a plurality of heat conducting holes are opened on the heat conducting pipe 121. The heat conducting pipe 121 starts to generate heat after being powered on. After being heated, the heat conducting pipe 121 transmits heat through the compressed air in the heat sealing device 100 used for the packaging equipment. The driving member 11 pushes the heat conducting pipe 121 to move toward the heat sealing portion 1021 on the second shell 102, and the heated air is ejected through the heat conducting holes on the heat conducting pipe 121 to heat the heat sealing portion 1021, so that it performs a heat sealing operation. After the heat sealing is completed, the compressed air is released to the parts to be packaged on the packaging equipment through the heat dissipation holes arranged below the heat sealing portion 1021 of the second shell 102, so as to quickly cool down the parts to be packaged on the packaging equipment, thereby making the parts to be packaged have a better sealing effect.

[0047] Based on the above heat-sealing device 100 for packaging equipment, the present invention also proposes a packaging equipment having a heat-sealing device 100 for packaging equipment, the packaging equipment also includes a guiding mechanism 2 and a base, the guiding mechanism 2 is connected to the base, and the heat-sealing device 100 for packaging equipment is arranged on the guiding mechanism 2.

[0048] See also Figure 3 and Figure 4 , which is a partial structural diagram of the packaging equipment of the present invention. The guide mechanism 200 includes a support assembly 21, a mounting assembly 22 and an adjustment assembly 23. The mounting assembly 22 is slidably connected to the support assembly 21. The mounting assembly 22 is mounted with a heat sealing device 100 for the packaging equipment. The adjustment assembly 23 is arranged on the mounting assembly 22. The adjustment assembly 23 can enable the mounting assembly 22 to drive the heat sealing device 100 for the packaging equipment to slide relative to the support assembly 21.

[0049] The support assembly 21 includes a support block body and a sheet metal mounting member (not marked in the figure) for connecting with the base, and the sheet metal mounting member is installed on the support block body. Two mounting rods (not marked in the figure) are installed on the two opposite top and bottom surfaces of the support block body, and the two mounting rods form a mounting assembly 22. A mounting block (not marked in the figure) is also connected between the two mounting rods of the mounting assembly 22, and two groups of guide shafts 232 are installed on both sides of the interior of the mounting block through the connection holes set thereon, and an adjustment shaft 233 is installed between the two groups of guide shafts 232 on the mounting block through the connection holes set thereon, and a digital position display (not marked in the figure) is also provided on the surface of the mounting block where the guide shafts 232 and the adjustment shaft 233 are installed. A cylindrical rotating member is installed inside the support block body of the support assembly 21, and the end of the cylindrical rotating member away from the support block body is fixedly connected to the mounting assembly 22 through a fastening connector (not marked in the figure), and an adjustment handle 231 is provided on the fastening connector. The adjusting handle 231, the adjusting shaft 233 and the two guide shafts 232 form an adjusting assembly 23. The mounting assembly 22 is fixedly connected to the heat sealing device 100 for packaging equipment through an L-shaped mounting plate. The packaging equipment pushes the L-shaped mounting plate to move through the adjusting shaft 233, and the two guide shafts 232 ensure that the L-shaped mounting plate moves stably along the length direction of the support block body of the supporting assembly 21 to adjust the distance between the heat sealing portion 1021 on the heat sealing housing 10 and the forming tube on the packaging equipment. Therefore, the packaging equipment having the heat sealing device 100 for packaging equipment of the present invention can be applicable to forming tubes of various sizes.

[0050] The heat sealing device 100 for packaging equipment of the present invention heats the heat-conducting component 12 inside itself and then transfers the hot air to the heat sealing part 1021 through the airflow for heat sealing. In this way, the packaging equipment no longer needs to repeatedly push the cylinder to perform the heat sealing operation during heat sealing, and the packaging equipment can achieve the effect of continuous heat sealing. At the same time, the temperature is more stable during heat sealing by the heat sealing device 100 for packaging equipment of the present invention, which solves the problem of limited production speed caused by uncertain heat sealing time and unstable temperature of the parts to be sealed in the packaging equipment, and meets the demand for rapid production of packaging equipment.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
