Heat sealing assembly and packaging equipment

The embodiment of the invention provides a heat sealing assembly and packaging equipment. The heat sealing assembly comprises a connecting structure and a heat sealing head. The connecting structure comprises a first fixing plate, a second fixing plate, a connecting rolling ball and a balance spring, wherein the connecting rolling ball is arranged between the first fixing plate and the second fixing plate, so that the first fixing plate can rotate relative to the second fixing plate by taking the connecting rolling ball as a rotation center; one end of the balance spring abuts against the first fixing plate, and the other end of the balance spring abuts against the second fixing plate; and the heat welding head is fixedly connected to the second fixing plate. The second fixing plate can beused for being connected with a displacement device. When the heat welding head acts on an object to be packaged, the heat welding head is moved and makes contact with the object to be packaged, under the effect of the conne
