Description

Technical Field

[0001] This utility model belongs to the field of PET bottle conveying technology, and in particular relates to a PET bottle infeed and bottle stabilization structure. Background Technology

[0002] In beer and beverage production, most manufacturers currently use pneumatic conveying systems to transport finished PET bottles for bottling. Before filling, the PET bottles are transported via a straight pneumatic conveyor section to a transitional stage involving a curved conveyor system, such as the star wheel dial, to ensure the bottles transition from a chaotic state to a stable, uniformly pitched state before entering the filling system. In traditional bottle feeding structures, a straight, tangential feeding method is often used, with a circular inner liner. Due to the differences in PET bottle shapes, under normal circumstances, when conveying narrow-necked bottles, irregularly shaped bottles, or other bottles with long, narrow necks and wide bodies at the junction of the straight and curved conveyors, the bottles often become misaligned. This significantly increases the risk of bottle jamming at the junction of the pneumatic feeding line and the star wheel dial. Bottle jamming can lead to wear and deformation of the equipment's conveyor channels and bottle damage, requiring emergency shutdowns for repairs, delaying production time, affecting efficiency, and in severe cases, disrupting production schedules.

[0003] Therefore, it is urgent to study a combined structure that ensures a smooth transition during the transport of slender-bottomed PET bottles, in order to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a PET bottle feeding and stabilizing structure. By setting up a straight inner guard plate, a straight outer guard plate, and a bottle mouth pressure plate, it guides and fixes the PET bottle during feeding while effectively preventing the bottle body from rebounding upon impact with the star wheel, thus solving the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a PET bottle feeding and stabilizing structure, comprising a bottle body transition star wheel and a neck star wheel coaxially arranged; outer bottle body protective plates and outer neck protective plates are respectively provided on the outer periphery of the bottle body transition star wheel and the neck star wheel; in use, the bottle body transition star wheel and the neck star wheel operate synchronously; the bottle body transition star wheel is located below the neck star wheel; straight outer protective plates B and A are respectively connected to the ends of the bottle body outer protective plates and the neck outer protective plates; it also includes a straight inner protective plate A that cooperates with the straight outer protective plate A to form a conveying channel A, and a straight inner protective plate B that cooperates with the straight outer protective plate B to form a conveying channel B; a bottle mouth pressure plate is also provided directly above the conveying channel A; the bottle body transition star wheel and the neck star wheel operate synchronously, with the bottle body transition star wheel below and the neck star wheel above, and together with the straight inner and outer protective plates, form a segmented conveying channel, forcibly guiding the PET bottle to smoothly transition from the straight pneumatic conveying section to the equal pitch curved conveying section.

[0007] Furthermore, both the outer protective plate of the bottle body and the outer protective plate of the bottle neck have an arc-shaped structure.

[0008] Furthermore, the bottom side of the inner straight protective plate B is higher than the upper surface of the outer protective plate of the bottle body and the transition star wheel of the bottle body.

[0009] Furthermore, the end of the straight inner guard plate A is provided with an arc-shaped section, which, together with the bottleneck outer guard plate, forms an arc-shaped transition conveying section.

[0010] Furthermore, guide portions are provided on opposite sides of the ends of the straight outer guard plate A and the straight inner guard plate A. The guide portions can reduce the impact of the PET bottle body at the junction, ensure that the PET bottle body enters the transition bottle stabilizing mechanism smoothly, and limit the left and right swing of the bottle body in the forward direction.

[0011] This utility model has the following beneficial effects:

[0012] This invention, through the setting of a straight inner guard plate, a straight outer guard plate, and a bottle mouth pressure plate, guides and fixes PET bottles into the bottle while effectively preventing the bottle body from impacting the star wheel and rebounding. It ensures that the PET bottle body does not tilt and enters the bottle stably during the process of the PET bottle entering the bottle from the straight line of the air conveyor to the curve of equal pitch, providing conveying stability. It is suitable for the beverage packaging field, especially for slender bottle necks.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] Please see Figure 1 and 3As shown in Figure 4, this utility model is a PET bottle inlet and stabilization structure, including a bottle body outer guard plate 20 and a neck outer guard plate 10 arranged coaxially and rotating synchronously during operation. A bottle body transition star wheel 2 is located below the neck star wheel 1. The bottle body outer guard plate 20 and the neck outer guard plate 10 are respectively arranged on the outer periphery of the bottle body transition star wheel 2 and the neck star wheel 1. A straight outer guard plate B21 and a straight outer guard plate A11, as well as a straight inner guard plate A12 and a straight inner guard plate B22 are respectively connected to the ends of the bottle body outer guard plate 20 and the neck outer guard plate 10. Both the bottle body outer guard plate 20 and the neck outer guard plate 10 have an arc-shaped structure.

[0024] The inner straight guard plate A12 and the outer straight guard plate A11 cooperate to form conveying channel A, and the inner straight guard plate B22 and the outer straight guard plate B21 cooperate to form conveying channel B; the bottle body transition star wheel 2 and the bottle body outer guard plate 20, as well as the neck star wheel 1 and the neck outer guard plate 10, respectively cooperate to form two equal pitch curved conveying sections; and a bottle mouth pressure plate 3 is set directly above the conveying channel A, and both the conveying channel A and the conveying channel B are straight conveying sections.

[0025] Several notches A201 and B101 are respectively provided on the outer periphery of the transition star wheel 2 on the bottle body and the star wheel 1 on the neck. The notches A201 and B101 have the same shape.

[0026] like Figure 2 As shown, the PET bottle 4 shakes too much before entering the bottle feeding and stabilizing structure. When the bottle is fed by air, the bottle body enters the bottle feeding and stabilizing structure first. At this time, the bottle mouth pressure plate 3 prevents the PET bottle 4 from tilting in the forward direction, ensuring that the PET bottle 4 enters the equal pitch curve conveying section in a more stable state.

[0027] Meanwhile, by adopting an equidistant offset design method, the bottle body transition star wheel 2 and the neck star wheel 1 ensure that during the transition from straight to curved conveying, the bottle mouth and body of the PET bottle 4 can always simultaneously contact the same position of the bottle body transition star wheel 2 and the neck star wheel 1 from the starting position of the station curve. As the bottle body transition star wheel 2 and the neck star wheel 1 rotate, and with the limiting of the straight outer protective plate B21 and the straight outer protective plate A11, the bottle mouth and body of the PET bottle 4 will gradually conform to the station curve of the bottle body transition star wheel 2 and the neck star wheel 1. This ensures that the center line of the PET bottle remains vertical and horizontal during the transition process from straight conveying to equidistant curved bottle entry, ultimately achieving a stable transition bottle entry effect where the PET bottle 4 does not tilt or jam during the bottle entry process.

[0028] The bottom side of the straight inner protective plate B22 is higher than the upper surface of the outer protective plate 20 and the transition star wheel 2 of the bottle body; and the upper surfaces of the straight outer protective plate A11 and the straight inner protective plate A12 are coplanar, and the bottom side of the straight outer protective plate A11 is higher than the upper surface of the bottleneck star wheel 1.

[0029] An arc-shaped section 13 is provided at the end of the straight inner guard plate A12. The arc-shaped section 13 and the bottleneck outer guard plate 10 cooperate to form an arc-shaped transition conveying section. Guide parts 14 are provided on opposite sides of the ends of the straight outer guard plate A11 and the straight inner guard plate A12.
