[0040] Reference Figure 4 According to the film wrapping machine 1 provided by some embodiments of the utility model, the guide mechanism 111 includes two guide plates 1111, and the guide plates 1111 are respectively arranged on opposite sides of the first conveyor line 10 that are perpendicular to the conveying direction. The distance between the two guide plates 1111 gradually decreases along the conveying direction. The gradually decreasing distance can play a role of confluence. The guide plates 1111 can enable the bottled products to enter the bottle separation mechanism 112 more smoothly, which is conducive to improving work efficiency.

[0041] Reference Figure 4According to the film wrapping machine 1 provided by some embodiments of the utility model, the bottle separation mechanism 112 includes multiple diverter plates 1121 and multiple partitions 1122. The diverter plates 1121 are arranged downstream of the guide mechanism 111. The diverter plates 1121 are connected to the first conveyor line 10. The diverter plates 1121 are offset on both sides along the conveying direction, which can divert the collected bottled products and achieve the effect of bottle separation and sorting; the partition plates 1122 are connected to the diverter plates 1121, and multiple partitions 1122 are arranged in parallel and spaced apart to form a channel. The bottled products are located in the channel, and the distance between adjacent partitions 1122 is slightly larger than the outer diameter of the bottled products, ensuring that the bottled products can be smoothly conveyed in the channel, which is conducive to improving work efficiency.

[0042] Reference Figure 1 , Figure 4 and Figure 5 According to the film packaging machine 1 provided by some embodiments of the utility model, the bottle separation mechanism 112 also includes a push rod assembly, which is arranged above the first conveyor line 10 and at the end of the channel. The push rod assembly includes a mounting frame 1123 and a plurality of push rods 1124. The mounting frame 1123 is fixedly connected to the frame 100. A conveying chain is arranged between the push rod 1124 and the mounting frame 1123. Driven by the conveying chain, the push rod 1124 can rotate around the mounting frame 1123. The spacing between adjacent push rods 1124 is determined according to the number of bottled products in each batch. When the push rod 1124 rotates to the position intersecting with the channel, the push rod 1124 is just located at the back of the bottled product. Under the pushing action of the push rod 1124, the bottled product is separated from the bottle separation mechanism 112. No manual operation is required, and the grouping of the bottled products is realized, which is conducive to improving work efficiency.

[0043] Reference Figure 1 and Figure 4 According to the film wrapping machine 1 provided by some embodiments of the utility model, the bottle separation mechanism 112 also includes a whole bottle assembly, and the whole bottle assembly is arranged directly above the channel. The whole bottle assembly includes a connecting column 1125 and a pressing block 1126. The connecting column 1125 is connected to the frame 100, and the pressing block 1126 sleeve 1126 is arranged on the connecting column 1125. The pressing block 1126 abuts against the bottled product. Specifically, a spring is provided at the connection between the connecting column 1125 and the frame 100, and the spring provides a downward elastic force. When the bottled product abuts against the pressing block 1126, the pressing block 1126 presses the bottled product downward, so that the bottled products are all kept at the same height, ensuring that the bottled finished products are arranged neatly, and can make the packaging film better fit the bottled product to improve the film coating quality.
