[0030] The bag making equipment body 2 on the frame 1 works to process the bag. When heat sealing is required, the electric push rod 4 is extended to move the lifting plate 6 downward. At this time, the sealing knife 14 contacts the bag on the cooling roller 5. As the downward movement continues, the sliding column 16 slides on the lifting plate 6, and the spring 17 contracts to store potential energy, which can buffer the contact force, ensuring the heat sealing effect while avoiding damage to the bag. At the same time, the water inside the heat exchange box 7 is pumped into the heat exchange tube 23 through the inlet pipe 8 by the machine pump, and the heat seal can be cooled in cooperation with the cooling roller 5 to avoid To avoid incomplete cooling and stretching deformation, the water after heat exchange flows back to the heat exchange box 7 through the return pipe 9 to complete the cycle. The reciprocating extension and contraction of the electric push rod 4 and the guided transportation of the cooling roller 5 can continuously perform heat sealing operations on the packaging bags. When it is necessary to disassemble, repair or replace the sealing knife 14, the positioning rod 21 can be pulled out of the positioning hole 19, and the limit of the plug-in column 18 is lost. Then the mounting plate 13 is pulled downward, and the plug-in column 18 can be removed from the plug-in hole 20, completing the disassembly operation of the sealing knife 14, which is convenient for maintenance or disassembly operations.

[0031] 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 principles of the present invention should be included in the protection scope of the present invention.
