Description

Technical Field

[0001] This utility model relates to the field of bottle cap detection technology, specifically a pneumatic conveying mechanism for bottle caps. Background Technology

[0002] The quality of bottled products depends on two factors: the quality of the contents, such as the liquid in a wine, and the quality of the bottle itself. Among these factors, the quality of the bottle cap not only affects the sealing effect but also plays a crucial role in the container's aesthetic appearance. Therefore, bottle cap inspection is an essential test for bottled product manufacturers before bottling.

[0003] In bottle cap inspection projects, bottle caps need to be transported to the inspection station by a conveyor mechanism. Existing conveyor mechanisms usually use belts or chains to transport the bottle caps, which rely on friction to move the bottle caps during the transport process. However, bottle caps are light and are prone to sliding relative to the belt or chain, making the bottle cap transport unsmooth. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a bottle cap pneumatic conveying mechanism.

[0005] The technical solution of this utility model is as follows:

[0006] A bottle cap pneumatic conveying mechanism includes a rectangular air plate, an air supply cover on the lower side of the air plate and a protective cover on the upper side.

[0007] The protective cover extends along the length of the air deflector and has openings at both ends. The protective cover and the air deflector work together to form a conveying channel.

[0008] The air supply hood extends along the length of the air vane and forms a pneumatic cavity with the air vane. An air inlet pipe is provided on the bottom wall of the air supply hood.

[0009] The air plate is provided with several air outlets that connect to the pneumatic chambers at intervals along the conveying direction. The air outlets are trapezoidal openings that gradually narrow along the conveying direction. The short side of the air outlet in the conveying direction extends downwards at an angle to the opposite side of the conveying direction, with a trapezoidal trough bottom plate that gradually widens. The two sides of the trough bottom plate are connected to the two sides of the air outlet, respectively, with trough side plates. The trough bottom plate and the two trough side plates cooperate to form an air duct that gradually narrows along the conveying direction.

[0010] Through several air outlets on the air deflector and the inclined air duct, a continuous forward airflow is formed in the conveying direction. After the bottle cap enters the conveying channel, the inclined airflow led out by the air duct generates an inclined forward thrust on the bottle cap. The inclined thrust can be divided into a component that pushes the bottle cap forward and a component that pushes the bottle cap upward. The upward pushing component can reduce the friction between the bottle cap and the air deflector when the bottle cap moves forward, ensuring that the bottle cap can be conveyed smoothly and stably.

[0011] In this application, the air outlet and the air duct are specially designed to taper along the conveying direction. Firstly, this can concentrate the air force and effectively act on the bottom and lower part of the bottle cap, avoiding air force dispersion and insufficient air force, which would result in poor conveying of the bottle cap. Secondly, it can increase the airflow velocity from the air outlet and improve the air force, which not only increases the thrust on the bottle cap but also improves the utilization effect of the airflow supplied by the fan, thereby reducing the working power of the fan.

[0012] In addition, the protective cover not only provides protection and prevents environmental airflow from interfering with the bottle cap transport, thus improving the stability of the bottle cap transport, but also forms a flow channel to restrain and guide the airflow coming out of the air outlet, which is conducive to pushing the bottle cap forward for transport.

[0013] Preferably, the bottom plate of the trough is inclined downward at an angle of 20° to 30°, which can generate sufficient pushing force without making the upward pushing force too large.

[0014] In the above scheme, the extension length of the bottom plate in the conveying direction is not less than the height of the trapezoid of the air outlet. That is, in the conveying direction, the lateral extension length of the bottom plate is not less than the lateral length of the air outlet, so as to ensure that the airflow can be guided by the air duct.

[0015] Furthermore, the two side plates of the trough gradually move away from each other from the edge of the bottom plate and extend towards the sides of the air outlet, so that the airflow in the air duct flows outward in a gradually diverging manner, avoiding turbulence or trickle phenomena that could cause unstable airflow and affect the smooth delivery of bottle caps.

[0016] Preferably, the taper of the air outlet is 1 / 2 to 3 / 4, and the length of the short side in the conveying direction is not less than 1 / 2 of the length of the long side, to ensure that the airflow has sufficient contact area with the bottle cap.

[0017] In a preferred embodiment, the air inlet pipe is located at one end of the bottom wall of the air supply hood near the upstream end in the conveying direction, and is configured to supply air at an angle in the conveying direction.

[0018] In another preferred embodiment, the air inlet pipe includes multiple pipes, which are respectively arranged in correspondence with several air ducts. This can improve the effective utilization of wind power and help ensure the balance of airflow between each air outlet, thereby improving the smooth delivery of bottle caps.

[0019] Preferably, the upper end of the air inlet pipe extends into the pneumatic cavity and bends at an angle in the conveying direction, with the outlet of the air inlet pipe facing the inlet of its corresponding air duct.

[0020] In some embodiments, the protective cover includes two separate side panels and a top panel. Each of the three panels has a mounting strip on its outer side. The side panels are fixed to the side wall of the air supply cover and / or the side of the air panel by the mounting strip. One end of the mounting strip on the top panel is hinged to the top of the mounting strip of one side panel, and the other end is fastened to the mounting strip of the other side panel by a snap-fit ​​structure, thereby facilitating the installation and removal of the protective cover.

[0021] Furthermore, the protective cover is equipped with two side guardrails and one top guardrail, with the three guardrails extending along the conveying direction. The two side guardrails are located on either side of the air outlet, and the top guardrail is located above the air outlet. Each of the three guardrails is equipped with a sliding rod. The sliding rod of the side guardrail passes through the side guard plate and is slidably connected to the corresponding mounting strip, while the sliding rod of the top guardrail passes through the top guard plate and is slidably connected to the corresponding mounting strip. Each of the three mounting strips has a bolt locking device at the corresponding sliding rod position. The three guardrails serve to limit and guide the bottle caps during conveying. The positions of the three guardrails are adjustable through the sliding rods and bolt locking devices, thus enabling the pneumatic bottle cap conveying mechanism to be adapted to bottle caps of different sizes.

[0022] This utility model provides a pneumatic bottle cap conveying mechanism. Through a set of air plates, air hoods, and protective covers, as well as several air outlets and inclined air ducts on the air plates, it utilizes airflow to generate a forward pushing force on the bottle caps for conveying them. Compared with traditional belt or chain conveyor methods, using wind power instead of friction ensures stable and smooth bottle cap conveying, preventing bottle caps from stalling.

[0023] In addition, the air outlet and air duct are specially designed to taper along the conveying direction. First, this can concentrate the air force and effectively act on the bottom and lower part of the bottle cap, avoiding air force dispersion and insufficient air force, which would result in poor bottle cap conveying effect. Second, it can increase the airflow velocity from the air outlet and improve the air force, which not only increases the thrust on the bottle cap, but also improves the utilization effect of the airflow supplied by the fan, thereby reducing the working power of the fan.

[0024] In addition, the protective cover not only provides protection and prevents environmental airflow from interfering with the bottle cap transport, thus improving the stability of the bottle cap transport, but also forms a flow channel to restrain and guide the airflow coming out of the air outlet, which is conducive to pushing the bottle cap forward for transport.

[0034] Example 1:

[0035] like Figures 1 to 3 As shown, this embodiment provides a pneumatic bottle cap conveying mechanism for conveying bottle caps to a bottle cap inspection device and docking with the conveying mechanism of the bottle cap inspection device. This pneumatic bottle cap conveying mechanism is mainly used, but not limited to, on bottle cap inspection devices designed by the applicant. These devices have a star wheel mechanism at the input end, which inputs bottle caps in a spaced and continuous manner. The pneumatic bottle cap conveying mechanism provided in this embodiment not only solves the problem of relative slippage that easily occurs in traditional belt or chain conveyor methods, but also solves the problem that in traditional belt or chain conveyor methods, the ends of the conveyor belt or chain are large arc shapes, making it impossible to tightly dock with the star wheel.

[0036] The pneumatic bottle cap conveying mechanism of this embodiment includes a wind plate 10, which is a long rectangular plate with its length direction being the conveying direction of the bottle caps. The bottle caps are conveyed on the top surface of the wind plate 10. For ease of subsequent explanation, the conveying direction is set to back to front in this embodiment.

[0037] A protective cover 20 is provided on the upper side of the air plate 10. The protective cover 20 extends along the length of the air plate 10 and has openings at both the front and rear ends. The protective cover 20 and the air plate 10 cooperate to form a conveying channel. During conveying, the bottle cap moves in the conveying channel.

[0038] The lower sealing cover of the air deflector 10 has an air supply hood 30, which extends along the length of the air deflector 10 and cooperates with the air deflector 10 to form a pneumatic cavity. An air inlet pipe 31 is provided on the bottom wall of the air supply hood 30, and several air outlets 11 connected to the pneumatic cavity are spaced apart along the conveying direction on the air deflector 10. The air inlet pipe 31 is connected to a fan. The fan supplies air into the pneumatic cavity through the air inlet pipe 31, and the air flows out from each air outlet 11 of the air deflector 10, pushing the bottle cap to move.

[0039] The air supply hood 30 includes a U-shaped profile that extends front and rear, with baffles sealing both ends. The air plate 10 covers the upper opening of the U-shaped profile.

[0040] The pneumatic conveying mechanism for bottle caps can be installed on the bottle cap detection equipment via the baffles at both ends of the air supply hood 30 or connected to the conveying mechanism of the bottle cap detection equipment via an independently set bracket. When connected, the top surface of the air plate 10 is directly connected to and flush with the input plane of the conveying mechanism of the bottle cap detection equipment.

[0041] In this embodiment, the air inlet pipe 31 is located at the end of the bottom wall of the air supply hood 30 near the upstream end in the conveying direction, and is configured to supply air at an angle in the conveying direction.

[0042] Combined Figure 3 and Figure 4 As shown, the air outlet 11 of the air plate 10 is a trapezoidal opening that gradually narrows along the conveying direction. The short side of the air outlet 11 in the conveying direction extends downward at an angle to the opposite direction of the conveying direction, with a trapezoidal trough bottom plate 12 that gradually widens. The two sides of the trough bottom plate 12 and the two sides of the air outlet 11 are respectively connected to trough side plates 13. The trough bottom plate 12 and the two trough side plates 13 cooperate to form an air duct that gradually narrows along the conveying direction.

[0043] Specifically, the opening shape of the air outlet 11 is trapezoidal, with the top (i.e., the short side of the aforementioned air outlet 11) and the bottom (i.e., the long side of the aforementioned air outlet 11) of the trapezoid being arranged parallel to each other, forming a shape that gradually narrows from back to front.

[0044] The bottom plate 12 extends backward and downward from the short side in front of the air outlet 11 at an angle of 20° to 30°, so as to generate sufficient pushing force without making the upward pushing force too large.

[0045] The extension length of the bottom plate 12 in the conveying direction is not less than the height of the trapezoid of the air outlet 11, that is, the bottom plate 12 extends backward to below or beyond the long side of the rear side of the air outlet 11, to ensure that the airflow can be guided by the air duct.

[0046] In addition, the two side plates 13 extend from the left and right edges of the bottom plate 12 of the trough in a gradually moving manner toward the left and right sides of the air outlet 11, so that the airflow in the air duct and in the vertical direction flows outward in a gradually diverging manner, avoiding turbulence or vortex phenomena that would cause unstable airflow and affect the smooth delivery of bottle caps.

[0047] In this embodiment, the pneumatic bottle cap conveying mechanism forms a continuous forward airflow in the conveying direction through several air outlets 11 on the air plate 10 and an inclined air duct. After the bottle cap enters the conveying channel, the inclined airflow led out by the air duct generates an inclined forward thrust on the bottle cap. The inclined thrust is divided into a component that pushes the bottle cap forward and a component that pushes the bottle cap upward. The upward pushing component can reduce the friction between the bottle cap and the air plate 10 when the bottle cap moves forward, ensuring that the bottle cap can be conveyed smoothly and stably.

[0048] In addition, using wind power instead of belt friction to transport bottle caps provides greater conveying force, ensuring smooth and stable delivery of bottle caps and preventing them from stalling.

[0049] In addition, the air outlet 11 and the air duct are specially designed to taper along the conveying direction. Firstly, this can concentrate the air force in the conveying direction, effectively acting on the bottom and lower part of the bottle cap to generate sufficient thrust, avoiding air force dispersion, which would lead to insufficient air force and poor conveying effect of the bottle cap. Secondly, it can increase the airflow velocity out of the air outlet 11, improve the air force, not only improve the thrust on the bottle cap, but also improve the utilization effect of the airflow supplied by the fan, thereby reducing the working power of the fan.

[0050] More specifically, the taper of the air outlet 11 is 1 / 2 to 3 / 4, and the length of the short side in the conveying direction is not less than 1 / 2 of the length of the long side. The length of the long side of the air outlet 11 is preferably less than the diameter of the bottle cap to ensure that the airflow has sufficient contact area with the bottle cap.

[0051] In this embodiment, the reason why the shape of the air outlet 11 is chosen to be trapezoidal rather than triangular is that, in addition to achieving the above-mentioned beneficial effects, it is also to have a certain lateral width in the left and right directions, so that the bottle cap will always have a balanced force on both sides to balance the bottle cap during the conveying process, and to avoid the bottle cap from tilting to the left or right, which would cause the bottle cap to interact with, for example, the protective cover 20, and hinder the forward and backward conveying of the bottle cap.

[0052] Refer to Figure 1 As shown in this embodiment, the protective cover 20 not only provides protection and prevents interference from ambient airflow on the bottle cap conveying, thus improving the stability of the bottle cap conveying, but also forms a flow channel to constrain and guide the airflow coming out of the air outlet 11, which is beneficial for pushing the bottle cap forward for conveying.

[0053] The protective cover 20 may specifically include two separate side guards 21 and a top guard 22. Each of the three guards has an installation strip 23 on its outer side. The side guards 21 are fixed to the side wall of the air supply cover 30 and / or the side of the air panel 10 by the installation strip 23. One end of the installation strip 23 on the top guard 22 is hinged to the top of the installation strip 23 of one side guard 21, and the other end is fastened to the installation strip 23 of the other side guard 21 by a snap-fit ​​structure, thereby facilitating the installation and disassembly of the protective cover 20.

[0054] In some embodiments, the size of the protective cover 20 can be set to match the size of the bottle cap to be conveyed, so as to limit the bottle cap and prevent it from tipping over in the conveying channel.

[0055] In this embodiment, to achieve a better effect, such as Figure 1 and Figure 5 As shown, the protective cover 20 has two side guardrails 24 and one top guardrail 25. These three guardrails extend along the conveying direction. The two side guardrails 24 are located on either side of the air outlet 11, symmetrically arranged relative to the center of the air outlet 11. The top guardrail 25 is located above the air outlet 11. Each of the three guardrails has a sliding rod 26. The sliding rod 26 of the side guardrail 24 passes vertically through the side guard plate 21 on its side and is slidably connected to the mounting strip 23 on that side. The sliding rod 26 of the top guardrail 25 passes vertically through the top guard plate 22 and is slidably connected to the corresponding mounting strip 23. Each of the three mounting strips 23 and the three guard plates has sliding holes for the sliding rods 26 to slide through. Each of the three mounting strips 23 has a bolt locking member 27 corresponding to the position of the sliding rod 26. The bolt locking member 27 is threaded onto the mounting strip 23, and its axial direction is perpendicular to the axial direction of the sliding rod 26. The bolt locking member 27 fixes the sliding rod 26 to the mounting strip 23 by screwing it in and pressing it against the cylindrical surface of the sliding rod 26.

[0056] The three guardrails serve to limit and guide the bottle caps during transport. The positions of the three guardrails are adjustable through the cooperation of the slide bar 26 and the bolt locking part 27, thus enabling the pneumatic bottle cap transport mechanism to be suitable for bottle caps of different sizes.

[0057] Example 2:

[0058] like Figure 6 As shown, the pneumatic bottle cap conveying mechanism provided in this embodiment is basically the same as that in Embodiment 1. The difference is that multiple air inlet pipes 31 are provided, each corresponding to a number of air ducts, which can effectively guide the airflow to the air ducts and improve the effective utilization of the air force. Furthermore, multiple air inlet pipes 31 are provided in the conveying direction. Since the pressure of the input airflow in each air inlet pipe 31 is equal, this helps to ensure the balance of airflow pressure at each air outlet 11, ensuring the balance of outflow airflow between each air outlet 11 and improving the smooth conveying of bottle caps.

[0059] Furthermore, the upper end of the air inlet pipe 31 extends into the pneumatic cavity and bends at an angle in the conveying direction. The outlet of the air inlet pipe 31 faces the inlet of its corresponding air duct. The air outlet direction of the air inlet pipe 31 is consistent with the guiding direction of the air duct, which is conducive to the airflow from the air inlet pipe 31 flowing into the corresponding air duct.
