Description

Technical Field

[0001] This utility model relates to a PET bottle anti-jamming mechanism, belonging to the technical field of PET bottle anti-jamming technology. Background Technology

[0002] PET bottles have become the mainstream material for beverage packaging due to their lightweight, impact resistance, high transparency, and good gas barrier properties. The trend of PET bottles shifting from traditional round shapes to square, oval, and other irregular shapes is a comprehensive result of the packaging industry responding to consumption upgrades and technological innovations. However, irregularly shaped bottles place higher demands on transportation.

[0003] Modern bottling production lines commonly employ bottle neck conveying technology (PET bottles are transported to the equipment via an air conveyor and then moved to the workstation by a bottle neck star wheel). As modern bottling equipment evolves towards higher speeds, the traditional star wheel structure becomes less adaptable to high-speed conditions, increasing the likelihood of bottle jamming. On one hand, the thin walls and relatively weak overall strength of PET bottles make them prone to deformation and jamming. On the other hand, the air conveyor system is susceptible to tilting due to friction and airflow, leading to bottle jamming upon entering the star wheel.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This utility model addresses the shortcomings of the prior art by providing a PET bottle anti-jamming mechanism, which can achieve vertical and stable conveying of PET bottles and ensure that there will be no jamming or tilting during the conveying process.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: A PET bottle anti-jamming mechanism includes a neck guard plate and a neck star wheel. The neck guard plate is an arc-shaped plate, and the neck star wheel is a rotating disk. The neck guard plate surrounds the outer side of the neck star wheel, forming a neck conveying channel between the inner ring of the neck star wheel and the neck guard plate. Multiple bottleneck slots are provided at equal intervals on the outer ring of the bottleneck star wheel. The bottleneck slots cooperate with the bottleneck of the PET bottle so that the bottle mouth of the PET bottle is hung on the bottleneck slot. A bottle neck pressure plate is fixed at the upper end of the neck star wheel. The distance between the bottle neck pressure plate and the neck star wheel is such that the bottle neck pressure plate presses down on the bottle neck of the PET bottle.

[0007] Furthermore, the outer diameter of the bottle neck pressure plate is larger than the outer diameter of the neck star wheel, so that the bottle neck pressure plate presses down on the bottle neck of the PET bottle before the PET bottle enters the neck slot.

[0008] Furthermore, the bottle neck pressure plate has multiple upward-curving slopes around its perimeter, each of which corresponds to a bottle neck slot, and the projection of the upward-curving slope onto the bottle neck star wheel is located on the front side of the bottle neck slot.

[0009] Furthermore, multiple support columns are vertically installed at the lower end of the bottleneck star wheel, and the support columns drive the bottleneck star wheel and the bottle mouth pressure plate to rotate.

[0010] Furthermore, a bottle mouth pressure plate support shaft is connected between the bottle mouth pressure plate and the bottle neck star wheel, and a first screw is installed on the upper surface of the bottle mouth pressure plate to fix the bottle mouth pressure plate and the bottle neck star wheel together through the bottle mouth pressure plate support shaft.

[0011] Furthermore, a bottle body guard plate is installed on the lower side of the neck guard plate. The bottle body guard plate is an arc-shaped plate. A bottle body star wheel is provided on the lower side of the neck star wheel. The bottle body guard plate surrounds the outer side of the bottle body star wheel, and a bottle conveying channel is formed between the bottle body guard plate and the inner ring of the bottle body star wheel.

[0012] Furthermore, the neck guard plate and the body guard plate are fixedly connected by a first connecting shaft, and a second screw is installed on the top of the neck guard plate to fix the neck guard plate, the body guard plate and the first connecting shaft together.

[0013] Furthermore, a second connecting shaft is vertically connected between the bottle body star wheel and the bottle neck star wheel.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: A bottle neck pressure plate is fixed to the upper end of the bottle neck star wheel. The distance between the bottle neck pressure plate and the bottle neck star wheel is just enough for the bottle neck pressure plate to press against the bottle neck of the PET bottle, so that the PET bottle does not tilt. The bottle neck pressure plate has multiple upward-curving slopes around its perimeter. The bottle neck of the PET bottle enters the lower surface of the bottle neck pressure plate at the upward-curving slopes. The upward-curving slopes are about 2mm up to ensure that the bottle neck can enter smoothly and prevent the top of the bottle neck from getting stuck on the edge of the bottle neck pressure plate.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0018] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0019] like Figure 1 As shown, this utility model provides a PET bottle anti-jamming mechanism, including a neck guard plate 5 and a neck star wheel 2. The neck guard plate 5 is an arc-shaped plate, and the neck star wheel 2 is a rotating disk. The neck guard plate 5 surrounds the outer side of the neck star wheel 2, forming a neck conveying channel between the inner ring of the neck star wheel 2 and the neck guard plate 5. Multiple bottleneck slots 201 are provided at equal intervals on the outer ring of the bottleneck star wheel 2. The bottleneck slots 201 cooperate with the bottleneck of the PET bottle 7 so that the bottle mouth of the PET bottle 7 is hung on the bottleneck slots 201.

[0020] A bottle neck pressure plate 3 is fixed at the upper end of the neck star wheel 2. The distance between the bottle neck pressure plate 3 and the neck star wheel 2 is just enough to press the bottle neck pressure plate 3 against the bottle neck of the PET bottle 7, preventing the PET bottle 7 from tilting. Figure 2 As shown.

[0021] The outer diameter of the bottle mouth pressure plate 3 is larger than the outer diameter of the neck star wheel 2, ensuring that the bottle mouth pressure plate 3 can also press down on the bottle mouth of the PET bottle 7 before the PET bottle 7 enters the neck slot 201.

[0022] The bottle neck pressure plate 3 has multiple upward-curving slopes 301 around its perimeter. Each upward-curving slope 301 corresponds to a bottle neck slot 201, and the projection of the upward-curving slope 301 onto the bottle neck star wheel 2 is located in front of the bottle neck slot 201. The PET bottle neck enters the lower surface of the bottle neck pressure plate 3 at the upward-curving slope 301, which is about 2mm upward, to ensure that the bottle neck can enter smoothly and to prevent the top of the bottle neck from getting stuck on the edge of the bottle neck pressure plate 3.

[0023] Multiple support columns 10 are vertically installed at the lower end of the bottleneck star wheel 2, and the support columns 10 drive the bottleneck star wheel 2 and the bottle mouth pressure plate 3 to rotate.

[0024] A bottle mouth pressure plate support shaft 4 connects the bottle mouth pressure plate 3 and the bottle neck star wheel 2. A first screw 8 is installed on the upper surface of the bottle mouth pressure plate 3 to fix the bottle mouth pressure plate 3 and the bottle neck star wheel 2 together through the bottle mouth pressure plate support shaft 4.

[0025] like Figure 1 and Figure 3 A bottle body guard plate 6 is installed on the lower side of the neck guard plate 5. The bottle body guard plate 6 is an arc-shaped plate. A bottle body star wheel 1 is provided on the lower side of the neck star wheel 2. The bottle body guard plate 6 surrounds the outer side of the bottle body star wheel 1, and a bottle body conveying channel is formed between the inner ring of the bottle body guard plate 6 and the bottle body star wheel 1. When the bottle mouth of the PET bottle 7 is suspended in the neck slot 201 for conveying, the bottle mouth is pressed by the bottle mouth pressure plate 3, and the bottle body is blocked by the bottle body guard plate 6 and the bottle body star wheel 1, ensuring that the PET bottle 7 can be conveyed stably and will not tilt due to the influence of the conveying air during the conveying process.

[0026] The neck guard plate 5 and the bottle body guard plate 6 are fixedly connected by a first connecting shaft 11. A second screw 9 is installed on the top of the neck guard plate 5 to fix the neck guard plate 5, the bottle body guard plate 6 and the first connecting shaft 11 together.

[0027] A second connecting shaft 12 is vertically connected between the bottle body star wheel 1 and the neck star wheel 2. During transmission, the bottle body star wheel 1, the neck star wheel 2, and the bottle mouth pressure plate 3 rotate together, while the neck guard plate 5 and the bottle body guard plate 6 are both fixedly installed.
