[0028] Referring to Figures 1 to 3 , the heat shrinkable film packaging equipment of the first aspect embodiment of the present utility model includes: a frame 100; a transportation mechanism, including a first conveyor 110 and a positioning component, the first conveyor 110 is arranged in the horizontal direction, the positioning component is arranged at the feeding end of the first conveyor 110, and the positioning component arranges a plurality of bottles neatly; a film feeding mechanism, including a film feeding component and a film sealing component, the film feeding component drives the shrinkable film roll to release the shrinkable film, so that the shrinkable film passes through the first conveyor 110 in the vertical direction, and the film sealing component is used for thermally cutting the shrinkable film; a heating mechanism, including a heating furnace 310 and a second conveyor 320, the feeding end of the heating furnace 310 is docked with the first conveyor 110, the discharging end of the heating furnace 310 is docked with the second conveyor 320, and air blowers 321 are arranged on both symmetric sides of the second conveyor 320.

[0029] The shrinkable film passes through the first conveyor 110 in the vertical direction. After a plurality of bottles enter the first conveyor 110 and are arranged neatly by the positioning component, the first conveyor 110 drives the bottles to contact the shrinkable film in the horizontal direction, so that the shrinkable film covers the bottles. Then the film sealing component thermally cuts the shrinkable film behind the bottles, so that the shrinkable film wraps the bottles up and down. Then, after passing through the heating furnace 310 for heating and shrinking, the bottles are tightly wrapped. Then, the cooling efficiency is improved through the second conveyor 320, the production efficiency is improved, and at the same time, automatic heat shrinkable film packaging is realized, reducing the labor intensity. The film sealing component cuts and separates the shrinkable film by thermal sealing. After separating the shrinkable film for wrapping the bottles, through thermal sealing, the separated cutting position on the original shrinkable film roll is heat-melted and connected, so that it is convenient for the film feeding component to continuously convey the shrinkable film.

[0030] It can be understood that referring to Figure 2 , the positioning component includes two guiding plates 131 and a plurality of positioning units 132. The two guiding plates 131 are symmetrically arranged on both sides of the first conveyor 110, and the plurality of positioning units 132 are respectively arranged on the two guiding plates 131. The positioning units 132 cooperate with the baffle 121 component to arrange a plurality of bottles neatly.

[0031] Specifically, referring to Figure 2 , the positioning unit 132 includes a first driving member and a positioning member. The first driving member is disposed on the guiding plate 131, and the first driving member drives the positioning member to move horizontally so that the positioning member is inserted between the bottles. The bottles are conveyed along the guiding plate 131, and the distance between the two guiding plates 131 is equal to twice the outer diameter of the bottle, so that two bottles are conveyed side by side each time. Then the first driving member drives the positioning member to extend. The positioning member closest to the shrink film blocks the conveyance of the bottles to achieve the positioning of the bottles. The remaining positioning members are inserted between two bottles, so that along the conveyance direction, the intervals between adjacent two bottles are arranged, and the distance of each interval remains stable. After arranging multiple bottles neatly, they are covered by the shrink film, and the shrink film is shrunk to achieve shaping. The first driving member can be a cylinder or an electric push rod.

[0032] It can be understood that the width of the positioning member gradually becomes smaller in the direction away from the first driving member, so that the whole positioning member is in a conical shape, which is convenient for the positioning member to extend between the bottles.

[0033] It can be understood that referring to Figure 2 , the first conveyor 110 is provided with a first bracket 122, and a baffle 121 is hinged to the first bracket 122. The first bracket 122 is provided with a limiting rod, and the limiting rod is disposed above the hinge point between the baffle 121 and the first bracket 122. The upper end of the baffle 121 can abut against the limiting rod. When the bottle deviates backward, the bottle contacts the baffle 121, and the baffle 121 rotates backward. When the baffle 121 rotates to the position where it abuts against the limiting rod, the limiting rod restricts the rotation of the baffle 121. At this time, the bottle is stationary, preventing the bottle from sliding backward out of the first conveyor 110.

[0034] It can be understood that referring to Figure 2 , the first conveyor 110 is provided with a dial rod assembly. The dial rod assembly includes a second bracket 143, a dial rod 141 and a second driving member 142.

Each time a plurality of bottles are packaged together, the number of bottles is large. To smoothly send all the bottles out of the first conveyor 110, the second driving member 142 drives the dial rod 141 to rotate. The dial rod 141 pushes the bottle out of the first conveyor 110. After the bottle contacts the shrink film, it continues to be conveyed forward, pulling the shrink film so that the upper and lower sides of the bottle are covered with the shrink film, and all the bottles are sent into the heating furnace 310. The second driving member 142 can be a cylinder. The movable end of the cylinder is hinged to the dial rod 141, and the cylinder itself is hinged to the frame 100, so that when the cylinder moves, it can rotate itself

[0035] It can be understood that, with reference to Figure 2 and Figure 3 , the film feeding assembly includes a first film feeding unit and a second film feeding unit. The first film feeding unit is arranged above the frame 100, and the second film feeding unit is arranged below the frame 100. The shrink film roll can rotate on the first film feeding unit, and the second film feeding unit is used to wind the shrink film sent from the first film feeding unit. After the shrink film is sent out from the film roll on the first film feeding unit, it passes through the first conveyor 110 in the vertical direction, and then is wound around the winding paper core of the second film feeding unit. The second film feeding unit drives the paper core to rotate by rotating the paper core, so as to drive the paper core to wind up the shrink film. After the bottle contacts the shrink film in the horizontal direction, the bottle continues to be conveyed. The second film feeding unit remains stationary, and the first film feeding unit continuously sends out the shrink film. The bottle stretches the shrink film, so that the bottle stands on the shrink film, and at the same time, the upper part of the bottle is also covered with the shrink film.

The two driven rollers 211 are arranged at intervals, which is convenient for directly placing the shrink film roll on the two driven rollers 211. When the second film feeding unit pulls the shrink film, the shrink film roll directly rotates on the driven roller 211, which is convenient and fast.

[0037] It can be understood that, with reference to Figure 2 and Figure 3 , the second film feeding unit includes two driving rollers 213 and a second conveying roller group 214. The two driving rollers 213 are arranged at intervals, and both of the two driving rollers 213 can abut against the paper core. The two driving rollers 213 cooperate to drive the paper core to rotate. The second conveying roller is used to tension the shrink film. When winding the shrink film around the paper core, the two driving rollers 213 are driven to rotate by a motor, so that the two driving pipes drive the paper core to rotate. The paper core pulls the shrink film to realize continuous conveying of the shrink film.

[0038] It can be understood that, with reference to Figure 2 and Figure 3, the film sealing assembly includes a third driving member 221, a sliding table module 224, a cutting knife 222 and a heating table 223.

The heating table 223 is arranged below the cutting knife 222. By driving the cutting knife 222 with the third driving member 221, the cutting knife 222 moves in the vertical direction, contacts the shrink film, and presses the shrink film on the heating table 223. The cutting knife 222 continuously applies pressure to the shrink film. At the same time, the heating table 223 generates heat to melt the shrink film. After melting, the shrink film on the film feeding assembly is heat-sealed, so that the shrink film on the film feeding assembly remains continuous. At the same time, the head and tail of the shrink film on the bottle are connected to form a ring to wrap the bottle.
