[0021] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0022] See Figures 1 to 2 This utility model provides a feeding mechanism and a packaging machine for conveying plastic bottles. The feeding mechanism includes:

[0023] Conveyor belt 1 has a conveying path arranged along a first direction;

[0024] At least one limiting structure includes a limiting plate 2 and a plurality of limiting posts 3. The limiting plate 2 can move relative to the conveyor belt 1 along a second direction and can move closer to or further away from the conveyor belt 1. The plurality of limiting posts 3 are arranged at intervals along the first direction on the limiting plate 2. A limiting cavity 4 is formed between two adjacent limiting posts 3 for accommodating the plastic bottle.

[0025] Under the action of external force, the limiting plate 2, in conjunction with the limiting post 3, is suspended above the conveyor belt 1 to restrict the movement of the plastic bottle or to move it away from the conveyor belt 1, thereby releasing the plastic bottle.

[0026] In this embodiment, plastic bottles are conveyed onto a conveyor belt 1. The conveyor belt 1 has a conveying path arranged along a first direction, which is a back-to-back direction, for conveying plastic bottles. Simultaneously, two limiting plates 2 and multiple limiting posts 3 are provided on both sides of the conveyor belt 1. The multiple limiting posts 3 are spaced apart on the two limiting plates 2 along the conveying path of the conveyor belt 1. The limiting plates 2 can move relative to the conveyor belt 1 along a second direction, which is a left-to-right direction. A limiting cavity 4 can be constructed between two adjacent limiting posts 3 to accommodate the plastic bottles. Under the action of external force, the limiting plates 2 can cause the limiting posts 3 to suspend and remain on the conveyor belt 1. Above or away from conveyor belt 1, when the limiting post 3 is close to conveyor belt 1, the limiting cavity 4 formed by adjacent limiting posts 3 can effectively restrict the position of the plastic bottle and prevent it from moving randomly; when the limiting post 3 is away from conveyor belt 1, the plastic bottle is allowed to pass freely and realize the release function. Of course, in order to limit the plastic bottle more stably, three limiting posts 3 can be set along the vertical direction of conveyor belt 1, corresponding to the bottle mouth, bottle body and bottle bottom of the plastic bottle respectively, so that the plastic bottle can be stably kept vertical on conveyor belt 1 without stopping the conveyor belt 1, so as to facilitate subsequent packaging operations.

[0027] The first direction is perpendicular to the second direction.

[0028] In this embodiment, the perpendicularity of the first direction to the second direction helps to more accurately control the restriction and release of the plastic bottle by the limiting structure. By moving the limiting plate 2 in a direction perpendicular to the movement direction of the conveyor belt 1, the position of the limiting post 3 relative to the plastic bottle on the conveyor belt 1 can be adjusted more flexibly and accurately, ensuring that each plastic bottle can be effectively and accurately positioned or released. This not only improves the accuracy of the feeding process, but also helps to improve the working efficiency and reliability of the entire production line.

[0029] The limiting structure also includes a cylinder, which is used to drive the limiting plate 2 to move along the second direction.

[0030] In this embodiment, when it is necessary to restrict the movement of the plastic bottle, the control system will trigger the cylinder to work, so that the cylinder pushes the limiting plate 2 closer to the conveyor belt 1 until the limiting post 3 is suspended above the conveyor belt 1, and separates the plastic bottles arranged in front and behind to form a limiting cavity 4 to accommodate the plastic bottle. Conversely, when it is necessary to release the plastic bottle, the cylinder will pull the limiting plate 2 away from the conveyor belt 1, the limiting post 3 will extend, and the plastic bottle will be conveyed with the conveyor belt 1.

[0031] A connecting rod 5 is provided between the cylinder and the limiting plate 2. A guide post 6 is provided at one end of the connecting rod 5 near the limiting plate 2. The limiting plate 2 is provided with a sliding groove 7 that slides with the guide post 6.

[0032] In this embodiment, the connecting rod 5 connects the cylinder and the limiting plate 2. The guide post 6 is located at the end of the connecting rod 5 near the limiting plate 2 to ensure that the limiting plate 2 moves precisely in a predetermined direction (i.e., the second direction). The slide groove 7 is located on the limiting plate 2 and forms a sliding fit with the guide post 6, which not only provides a guiding function but also ensures the stability and accuracy of the limiting plate 2 during the movement.

[0033] The cylinder's extension and retraction direction is set along the first direction, and the slide groove 7 is set at an angle to the second direction.

[0034] In this embodiment, by setting the extension and retraction direction of the cylinder to be along the first direction, and since the slide 7 is set at an angle to the second direction, space can be utilized more flexibly and the limiting plate 2 can be more smooth and stable when approaching or moving away from the conveyor belt 1.

[0035] The conveyor belt 1 is provided with a baffle 8 along the first direction to divide the conveyor belt 1 into a first conveying area 9 and a second conveying area 10.

[0036] In this embodiment, a baffle 8 is provided in the middle of the conveyor belt 1 along the first direction, which is used to cooperate with the limiting post 3 to separate each plastic bottle in the front-back and left-right directions, so as to avoid the collision between the plastic bottles and the tilting situation.

[0037] The baffle 8 has a first side and a second side arranged opposite to each other. The first side and the second side are respectively arranged facing the first conveying area 9 and the second conveying area 10, and at least one of them is provided with an arc-shaped groove. The opening of the arc-shaped groove is arranged facing the limiting plate 2.

[0038] In this embodiment, the arc-shaped groove (not shown) provides additional guidance for the plastic bottle. By adjusting the shape and position of the arc-shaped groove, the plastic bottle can transition smoothly, reducing the possibility of jamming or blockage. The opening of the arc-shaped groove is positioned facing the limiting plate 2, allowing for more precise control of the plastic bottle's position as the limiting plate 2 moves closer to or away from the conveyor belt 1. For example, when the limiting plate 2 approaches the conveyor belt 1, the arc-shaped groove can serve as an auxiliary positioning point, ensuring that the plastic bottle accurately enters the limiting cavity 4.

[0039] The end of the limiting post 3 that is away from the limiting plate 2 has a pointed tip.

[0040] In this embodiment, due to the reduced contact area, the limiting post 3 can more accurately separate the plastic bottle, thereby providing a more precise positioning effect.

[0041] This embodiment also provides a packaging machine, including the feeding mechanism described above. The specific structure of the packaging machine is the same as described in the above embodiment. Since this packaging machine adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought about by the technical solutions of the above embodiment, which will not be described in detail here.
