DETAILED DESCRIPTION

The double-layer bubble type heat insulation film produced by the equipment comprises a base film 7 made of transparent linear low-density polyethylene. The upper end of the base film 7 is ultrasonically bonded with a surface film 8. The surface film 8 is made of high-pressure polyethylene material and has bubbles 9 formed by adsorption. The base film 7 is bonded with buffer balls 10 made of sponge balls. The buffer balls 10 are located in the bubbles 9. The base film 7, the surface film 8 and the buffer balls 10 form a single-layer bubble film state. Two single-layer bubble films are bonded to form a double-layer bubble type heat insulation film. An adhesive layer 11 is formed in the middle during bonding. The double-layer bubbles 9 and the buffer balls 10 not only have strong buffering effect but also have strong heat insulation performance. The double-layer bubble type heat insulation film has the effects of double-layer air cushion isolation and buffer ball 10 isolation. The equipment for producing the double-layer bubble type heat insulation film comprises a pretreatment assembly 1. The pretreatment assembly 1 is used for bonding and connecting the base film with the buffer balls. The pretreatment assembly 1 comprises a first frame body 101. The upper end of the first frame body 101 is rotatably provided with a first guide roller 102 for introducing the base film. The inside of the first frame body 101 is rotatably provided with a feeding roller 103 for feeding the buffer balls. One side of the first frame body 101 is fixedly provided with a bubble forming assembly 2. The bubble forming assembly 2 adsorbs the surface film into bubbles and then bonds the bubbles with the base film to form a single-layer bubble film state. The bubble forming assembly 2 comprises a second frame body 201. The second frame body 201 is rotatably provided with an adsorption roller 202. The upper end of the second frame body 201 is rotatably provided with a second guide roller 203 for introducing the surface film. One end of the adsorption roller 202 is rotatably provided with an air extraction assembly 3 for forming negative pressure in the adsorption roller 202. One side of the second frame body 201 is fixedly provided with a bonding assembly 4 for bonding the single-layer bubble film into a double-layer bubble film. The pretreatment assembly 1, the bubble forming assembly 2 and the bonding assembly 4 are both two groups and symmetrically distributed. The two ends of the air extraction assembly 3 are in communication with the adsorption rollers 202 of the two bubble forming assemblies 2. The upper parts of the two bonding assemblies 4 are fixedly provided with a support frame 5. The upper end of the support frame 5 is rotatably provided with a winding roller 6 for winding the finished product.

The surface film is conveyed and adsorbed by the adsorption roller 202 to form a concave state in the bubble shape. When the base film carrying the buffer ball passes through the adsorption roller 202, the buffer ball is located in the inside of the concave state. When the base film is combined with the surface film, the concave state forms the bubble, and the buffer ball is encapsulated in the inside of the bubble, forming the double buffering effect.
