Description

Technical Field

[0001] This utility model belongs to the field of aluminum can aerosol production technology, specifically relating to a flexible screening system for aluminum can aerosol production lines. Background Technology

[0002] The current production process for aluminum can aerosols mainly includes the following steps: liquid filling, valve installation, propellant filling, water bath leak testing, button installation, outer cap installation, boxing, and cartoning. To ensure product quality, strict quality inspections are required on the product and its packaging at different stages of production. For detailed procedures, please refer to [link to relevant documentation]. Figure 11 As shown; the above process has the following two problems:

[0003] Question 1: After installation, each aerosol can is inspected for weight and components. If the weight or components are intact, the aerosol can is conveyed to the next step; if it fails, it is removed from the production line by a rejection device. Subsequently, manual re-inspection is conducted to determine whether it should be scrapped or returned to the production line for further inspection. Currently, most aluminum can rejection devices use a single cylinder to remove defective products. However, during the rejection process, due to the rapid reaction and high impact force of the cylinder, aluminum cans are easily dented, rendering them defective. Furthermore, the movement of the kicked-out aluminum cans is uncontrollable, and impacts can also deform them, rendering them unusable. In fact, most rejected aluminum cans can be restored to acceptable quality through manual installation or re-weighing, but the defects in the rejection device lead to material waste.

[0004] Question 2: Each piece of equipment performs random sampling of products at the back end. However, only a few devices on the market have built-in sampling functions; most still require operators to directly take samples from the production line for sampling. This method results in inconsistent sampling times and quantities, leading to significant sampling deviations. Furthermore, to ensure personnel safety, the sampling process requires machine shutdown, further reducing production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a flexible screening system for aluminum can aerosol production lines, used to screen whether aluminum can aerosols are missing their outer caps. While ensuring high-speed production of the production line, it avoids damage to the aluminum can aerosols caused by the removal device, thereby reducing the scrap rate of aerosol production. At the same time, it avoids manual sampling and ensures that aluminum can aerosols can be automatically sampled at regular intervals and in quantitative quantities.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A flexible screening system for an aluminum can aerosol production line, including an automatic transmission device; a flexible screening device is installed on one side of the automatic transmission device, and a screening storage structure is installed on the other side of the automatic transmission device. There is a transmission runway arranged below the screening storage structure; the transmission runway is installed on the automatic transmission device and has a certain interval from the screening storage structure; a guiding block is arranged at the front end of the side fence on the side of the automatic transmission device where the screening storage structure is located.

[0007] The screening storage structure has two inlets, one inlet is directly opposite to the flexible screening device, and the other inlet is located on the conveyor belt of the automatic transmission device; each inlet corresponds to a storage area.

[0008] Further, the flexible screening device includes a support frame, a plurality of hinge seats A arranged on the support frame, a flexible finger assembly A, a plurality of cylinders A, and a valve island; the support frame is fixed on the automatic transmission device;

[0009] The flexible finger assembly A is composed of multiple flexible fingers with increasing lengths. Each flexible finger is assembled on the hinge seat A through a hinge pin and a bearing, and the tail end of the flexible finger is hinged to the cylinder A with an attached hinge seat; the other end of the cylinder A is fixed on the support frame through a hinge seat B; the valve island is installed at the bottom of the support frame, and the air holes on the cylinder A are connected to the air holes on the valve island through air conveying pipelines.

[0010] Further, the support frame is a "C" - shaped structure, composed of a lower support plate, an upper support plate, and a connecting vertical plate connecting the middle of the lower support plate and the upper support plate; the hinge seat A is arranged on the upper support plate, and the hinge seat B is arranged on the lower support plate; a positioning sensor is also arranged on the upper support plate.

[0011] Further, in the flexible finger assembly A, the number of flexible fingers is at least three, the lengths increase in sequence, and the end of the flexible finger is a bevel.

[0012] Further, there is another structural solution for the flexible screening device in the present utility model, which includes a machine base, a flexible component B, a connecting shaft, a plurality of cylinders B, a rack, and a valve island; the number of racks is the same as the number of cylinders B; the machine base is fixed on the automatic transmission device, and a convex platform is provided at one end thereof. The connecting shaft is arranged on the convex platform of the machine base through a base and a bearing; a plurality of cylinders B are installed at the other end of the machine base; the racks are arranged in sequence on the convex platform and are located below the connecting shaft; each rack is correspondingly connected to a cylinder B; the valve island is fixed on the back of the machine base; the air holes on the cylinder B are correspondingly connected to the air holes on the valve island;

[0013] The flexible component B is composed of multiple flexible fingers with increasing lengths. A semi - circular gear is provided at the end of each flexible finger, and the flexible fingers are arranged on the connecting shaft through the semi - circular gears, and the semi - circular gears are correspondingly meshed with the racks below them.

[0014] Furthermore, in the flexible component B, the number of flexible fingers is at least three, with the lengths increasing sequentially, and the ends of the flexible fingers are beveled.

[0015] Furthermore, a positioning sensor is installed on the feed end of the machine base near the automatic conveying device.

[0016] Furthermore, the drainage block has a triangular structure.

[0017] During the filling stage, aluminum can aerosols are filled with active liquid and propellant. However, if the aluminum can is damaged after the propellant is filled, the active liquid and propellant cannot be separated and recycled. The entire aluminum can aerosol can must be scrapped. In addition, there are many installation stations for aluminum can aerosols, and the frequency of removal during the production process is high. Both of these factors lead to a high scrap rate on the production line.

[0018] This invention effectively solves the problem of bottle and can scrapping caused by the kicking mechanism in aluminum can aerosol production lines. Eliminating damage to the cans from the kicking device significantly improves production line efficiency and reduces production costs. This invention features a simple design, stable operation, low unit investment cost, and a significant return on investment. Attached Figure Description

[0031] Combination Figures 1-4 As shown, this utility model provides a flexible screening system for an aluminum can aerosol production line, including an automatic conveying device 1; a flexible screening device 2 is installed on one side of the automatic conveying device 1, and a screening and storage structure 3 is installed on the other side of the automatic conveying device 1. A transmission track 4 is provided below the screening and storage structure 3; the transmission track 4 is installed on the automatic conveying device 1 and is spaced apart from the screening and storage structure 3; a guide block 5 is provided at the front end of the side railing of the automatic conveying device 1 on the side of the screening and storage structure 3; the guide block 5 has a triangular structure; the guide block is designed with a beveled side structure, which can guide the aluminum can aerosol to deflect to the right side of the track along a predetermined path, ensuring that each can of product can effectively interact with the screening and storage structure 3. A protective cover is also provided on the flexible screening device 2.

[0032] The screening and storage structure 3 has two inlets, one directly opposite the flexible screening device 2, and the other located on the conveyor belt of the automatic conveying device 1; each inlet corresponds to a storage area. For example... Figure 1 As shown, the screening and storage structure 3 is mounted on the automatic conveying device 1 via a fastener 8, which is commercially available. The screening and storage structure 3 has two areas: one for temporarily storing substandard aluminum can aerosols, and the other for storing sampled parts, thus enabling parallel sorting and sampling operations.

[0033] The function of the automatic conveying device 1 is to transport the aerosol product from the previous station to the next station. The flexible screening device 2 is fixed to the automatic conveying device 1, and can effectively screen the aluminum can aerosol as it passes by. The transmission track 4 is fixed to the right side of the automatic conveying device 1 and is synchronized with the automatic conveying device 1 to ensure consistent speed and ensure process continuity.

[0034] The flexible screening device 2 includes a support frame 21, a plurality of hinge seats A22 arranged on the support frame 21, a flexible finger assembly A23, a plurality of cylinders A24, and a valve island 6; the support frame 21 is fixed on the automatic transmission device 1; the flexible finger assembly A23 consists of multiple flexible fingers with increasing lengths, and each flexible finger is assembled on the hinge seat A22 through a hinge pin 25 and a bearing 26, and the tail end of the flexible finger is hinged to the cylinder A24 with an attached hinge seat; thus, the flexible finger and the cylinder A form a short link mechanism, and when the cylinder A acts, it can drive the flexible finger to rotate; the other end of the cylinder A24 is fixed on the support frame 21 through a hinge seat B27; the valve island 6 is installed at the bottom of the support frame 21, and the air holes 241 on the cylinder A24 are all connected to the air holes 61 on the valve island 6 through air pipelines (the air pipelines are not shown in the figure); the valve island 6 is connected to an external compressed air source through an air pipeline to control the movement of the cylinder A and the action of the flexible finger. In this embodiment, the valve island 6 is equipped with a total of 12 control modules, which independently control 12 flexible fingers; the valve island is also provided with a communication interface 62 to communicate with an external CPU, and at the same time, the positioning sensor 7 is also linked with the external CPU to send an action signal to start the entire device.

[0035] In this embodiment, the support frame 21 is of a "C" - shaped structure, and is composed of a lower support plate 211, an upper support plate 212, and a connecting vertical plate 213 connecting the middle of the lower support plate 211 and the upper support plate 212; the hinge seat A22 is arranged on the upper support plate 212, and the hinge seat B27 is arranged on the lower support plate 211 to ensure the stable operation of the entire mechanism; a positioning sensor 7 is arranged on the upper support plate 212, and the positioning sensor 7 is arranged near the entrance end of the automatic transmission device 1 to detect whether the product is missing an outer cover.

[0036] In the flexible finger assembly A23, the number of flexible fingers is at least three, the lengths increase in sequence, and the end of the flexible finger is a bevel. The inclination angle of each flexible finger is the same and the width is uniform, and any two adjacent flexible fingers form a smooth bevel with the same slope; under the condition of the same swing angle, these flexible fingers can jointly form a continuous bevel, which is suitable for the screening of different aluminum can aerosols.

[0037] As Figure 8 shown, it is the working state diagram of the flexible screening system in Embodiment 1. In the figure: a is a qualified aluminum can aerosol, which will continue to flow to the next assembly or packaging station along with the conveyor belt; b is a sampled sample set according to the quality monitoring requirements, and is temporarily stored in one of the areas of the screening storage structure; c is an unqualified aluminum can aerosol (the unqualified product identified as missing an outer cover), which will be removed by the flexible screening device and enter another area of the screening storage structure through a specific path, and is separated from the main production line.

[0038] As Figure 9As shown, when a defective product passes the positioning sensor 7, the three rotating fingers will rotate downwards by 90° in sequence with a certain time difference. These three rotating fingers form a temporary guide wall, and the defective product will move obliquely along this inclined guide wall. After the defective product passes the guide wall formed by the fingers, the fingers will immediately rotate and reset, awaiting the next signal. The defective product will eventually be guided to the screening and storage structure 3. Similarly, when sampling is required, the fingers will guide the aluminum cans to the sampling can storage area of ​​the screening and storage structure 3 according to a timing program. When a qualified aluminum can passes, the fingers will not rotate, and the qualified product will proceed to the next station via the conveyor belt. This design effectively adapts to high-speed production lines, especially when multiple aluminum cans of aerosol pass through simultaneously, such as... Figure 10 As shown. Example 2

[0039] See Figures 5-7 In this embodiment, the flexible screening device 2 includes a base 31, a flexible component B32, a connecting shaft 33, multiple cylinders B34, racks 35, and a valve island 6. The number of racks 35 is the same as the number of cylinders B34. The base 31 is fixed on the automatic transmission device 1, and one end of it is provided with a boss 311. The connecting shaft 33 is mounted on the boss 311 of the base 31 through a base and bearings. Multiple cylinders B34 are installed at the other end of the base 31. The racks 35 are sequentially arranged on the boss 311 and located below the connecting shaft 33. Each rack 35 is connected to a corresponding cylinder B34. The valve island 6 is fixed on the back of the base 31. The air holes 341 on the cylinders B34 are connected to the air holes 61 on the valve island 6. A positioning sensor 7 is provided at the inlet end of the base 31 near the automatic transmission device 1. The valve island is connected to the central processing unit (CPU) through a communication line, and the positioning sensor 7 is also connected to the CPU to control the start of the flexible screening device.

[0040] The flexible component B32 consists of multiple flexible fingers of increasing length, each finger ending in a semi-circular gear 321. The fingers are mounted on the connecting shaft 33 via the semi-circular gears 321, which mesh with a rack 35 below them. The module of the rack 35 is the same as that of the semi-circular gears 321. When the cylinder B moves, it pushes the rack forward, thereby driving the fingers to rotate. The flexible component B32 has at least three flexible fingers, with increasing lengths, and the tips of the fingers are beveled.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit this utility model. Any minor modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of this utility model should be included within the protection scope of this utility model's technical solution.
