Description

Technical Field

[0001] This utility model relates to the field of film wrapping machine technology, and in particular to a narrow mesh chain conveyor structure for a film wrapping machine. Background Technology

[0002] During the packaging process of bottles using a film wrapping machine, the machine wraps a plastic film around the object and uses its heat shrinking device to heat shrink the plastic film, forming a layer of packaging on the outside of the object.

[0003] However, existing products, such as PTE petal bottle bottoms, cans, and three-piece cans, are prone to tipping over during the transfer process because the bottom is not horizontal. Furthermore, the single narrow mesh chain is stretched after running for a long time and cannot be tensioned independently, which easily causes tooth skipping and affects the overall processing and production efficiency. Utility Model Content

[0012] Furthermore, each of the connecting plates is provided with a plurality of first fixing holes and a plurality of second fixing holes, with the plurality of first fixing holes located above the plurality of second fixing holes.

[0013] Furthermore, the mounting plate is provided with a plurality of connection holes, each of which communicates with a first fixing hole, or each of which communicates with a second fixing hole.

[0014] The beneficial effects of this utility model are as follows: by using the narrow mesh chain conveyor structure of this film wrapping machine, through the cooperation of the mounting plate, connecting components, chain, gear and rotating wheel, the tension of the chain can be well limited, avoiding the easy occurrence of tooth skipping.

Detailed Implementation

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings of the embodiments. This utility model is not limited to the following specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0018] like Figures 1 to 2 As shown, a narrow mesh chain conveyor structure for a film wrapping machine includes: a mounting plate 100, a connecting assembly, a chain 300, a gear 400, and a rotating wheel 500; the connecting assembly is disposed on the mounting plate 100, one end of the mounting plate 100 is provided with a first protective shell 600, and the other end is provided with a second protective shell 700; the gear 400 and the rotating wheel 500 are both rotatably disposed on the mounting plate 100, the gear 400 is located inside the first protective shell 600, and the rotating wheel 500 is located inside the second protective shell 700; the chain 300 is movably sleeved on the outside of the gear 400 and the rotating wheel 500.

[0019] Specifically, the mounting plate 100 is provided with a limiting block 800, one end of which is located inside the first protective shell 600 and the other end inside the second protective shell 700. The first protective shell 600 is provided with a first adjusting block 610 and a second adjusting block 620, the first adjusting block 610 being located on one side of the gear 400 and the second adjusting block 620 being located on the other side of the gear 400. The first adjusting block 610 has a first curved surface 611, and the chain 300 movably abuts against the first curved surface 611. The second adjusting block 620 is provided with a limiting knob 621, the limiting knob 621 being rotatably mounted on the second adjusting block 620, and one end of the limiting knob 621 movably abuts against the chain 300. The second protective shell 700 is provided with a third adjusting block 710, the third adjusting block 710 being located on one side of the rotating wheel 500. The third adjustment block 710 has a second curved surface 711, and the chain 300 is in movable contact with the second curved surface 711.

[0020] In the above embodiment, the connecting assembly includes two connecting plates 200, both of which are detachably connected to the mounting plate 100. Each connecting plate 200 has a plurality of first fixing holes 210 and a plurality of second fixing holes 220, with the plurality of first fixing holes 210 located above the plurality of second fixing holes 220. The mounting plate 100 has a plurality of connecting holes, each of which communicates with a first fixing hole 210 or each of which communicates with a second fixing hole 220.

[0021] This conveyor structure requires an external film wrapping machine and must be driven by an external drive source. Specifically, the external film wrapping machine is connected to the chain 300, and the external drive source drives the gear 400 to rotate, which in turn drives the chain 300 to rotate.

[0022] Furthermore, due to the presence of a first adjusting block 610, a second adjusting block 620, and a third adjusting block 710, with the first adjusting block 610 having a first curved surface 611 and the third adjusting block 710 having a third curved surface, the movement path of the chain 300 can be well guided. Then, the limiting knob 621 can restrict the movement path of the chain 300. In other words, if the limiting knob 621 is not tightened, the chain 300 passing near the second adjusting block 620 will bulge due to the lack of restriction, causing it to be too loose during transmission and resulting in skipped teeth with the gear 400. Therefore, by tightening the limiting knob 621 to abut against and restrict the transmission position of the chain 300, skipped teeth can be prevented. That is, the tightness of the limiting knob 621 is related to the length of the chain 300. Furthermore, the connection position of the mounting plate 100 on the connecting plate 200 also determines the tension of the chain 300. If the chain 300 is relatively thick and may not be able to pass between the limiting block 800 and the mounting plate 100, the mounting plate 100 is installed at the position of several second fixing holes 220, which makes the gap between the mounting plate 100 and the limiting block 800 larger, ensuring that the chain 300 can pass normally. Conversely, if the chain 300 is relatively thin, the mounting plate 100 is installed at the position of several first fixing holes 210, ensuring that the chain 300 can pass normally and providing a good limiting effect for the chain 300.

[0023] In summary, the above embodiments are not limiting embodiments of this utility model. Any modifications or equivalent variations made by those skilled in the art based on the substantive content of this utility model are within the technical scope of this utility model.
