Description

Technical Field

[0001] This invention relates to the field of bottle cap packaging equipment technology, specifically to a bottle cap inner gasket installation system and its usage method. Background Technology

[0002] During the bottle cap production process, gaskets are typically installed inside the cap to provide a seal. Traditional gasket installation methods are mostly done manually, which is not only inefficient and costly, but also prone to quality problems such as uneven installation or misalignment due to human error.

[0003] Currently, there are some automated bottle cap gasket installation devices on the market, such as those that use pressure cylinders and push cylinders to install gaskets, or devices that use vacuum generators and gasket suction heads. However, most existing devices have the following shortcomings: First, the gasket installation efficiency still has room for improvement, with most devices only able to process one bottle cap at a time; second, the transfer of bottle caps between conveyor belts lacks an effective buffering and separation mechanism, easily causing bottle cap accumulation or jamming; and third, there is a lack of online detection and automatic sorting functions for gasket installation quality, making it difficult to ensure product consistency. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a bottle cap inner gasket installation system and its usage method. This system enables efficient and automated installation of bottle cap inner gaskets and improves production efficiency, reduces labor costs, and ensures product quality through a reasonable conveyor belt connection and buffer design, dual-station synchronous installation, and online detection and sorting functions.

[0005] The present invention is achieved through the following technical solution: a bottle cap inner gasket installation system, comprising a feeding device for placing bottle caps onto a first conveyor belt, wherein the bottle caps are sequentially passed through an inspection area for testing bottle caps under the drive of the first conveyor belt, two gaskets are simultaneously installed into the operation area inside two bottle caps respectively, and then enter the second conveyor belt one by one under the guidance of an inclined guide device, wherein the bottle caps are sequentially passed through a testing area for appearance and size testing and a unloading area under the drive of the second conveyor belt.

[0006] In use, this invention achieves automatic feeding, automatic installation, online detection, and automatic sorting of bottle cap inner gaskets through the coordinated operation of a feeding device, a first conveyor belt, an inspection area, an operation area, an inclined guide device, a second conveyor belt, a testing area, and a discharging area, resulting in a high degree of automation. The operation area can install gaskets on two bottle caps simultaneously, improving installation efficiency. The inclined guide device allows the bottle caps to smoothly transition from the first conveyor belt to the second conveyor belt and separates two simultaneously installed bottle caps one by one, which is beneficial for subsequent inspection and discharging.

[0007] Preferably, the inclined guide device includes a first guide channel arranged parallel to the first conveyor belt, a second guide channel arranged parallel to the second conveyor belt, and an inclined channel connecting the first guide channel and the second guide channel and arranged at an inclination. The first conveyor belt side frame and the second conveyor belt side frame form a buffer area to support the bottle cap.

[0008] In use, the inclined guide device is equipped with a first guide channel, an inclined channel, and a second guide channel. It also utilizes the first and second conveyor belt side frames to form a buffer area, which can temporarily buffer bottle caps located at the rear end when the first conveyor belt stops intermittently. This allows two bottle caps installed at the same time to be automatically separated, preventing bottle caps from stacking on the second conveyor belt. This ensures that the bottle caps are tested one by one in the subsequent testing area, improving the accuracy of the test.

[0009] Preferably, the operating area is provided with a support, on which two material tubes for placing the gasket are installed. The diameter of the material tube outlet is smaller than the diameter of the gasket. The support is also provided with a support that slides along the height direction. Two pneumatic suction cups arranged along the bottle cap arrangement conveying direction are rotatably connected to the support via a first rotating shaft. The pneumatic suction cups are also provided with several air ports arranged circumferentially and connected to an air pump. The two pneumatic suction cups are located directly below the two material tubes.

[0010] In use, this preferred solution utilizes two material tubes, a liftable support, a first rotating shaft, and two pneumatic suction cups in the operating area to adsorb and install two pads at once, resulting in high installation efficiency. The diameter of the material tube outlet is smaller than the diameter of the pad, preventing the pad from falling off naturally when not in use. The pneumatic suction cups are equipped with multiple air ports around the perimeter, making adsorption and blowing more uniform and improving the reliability of pad adsorption and release.

[0011] Preferably, the support is also provided with a first cylinder extending toward the bottle cap. The first cylinder and the support are located on both sides of the first conveyor belt. The extended end of the first cylinder is fixedly connected to a fixing clamp. The limiting plate on the first conveyor belt cooperates with the fixing clamp to squeeze the bottle cap located at the lower end of the material tube.

[0012] In use, the first cylinder and the fixing clamp cooperate with the limiting plate on the first conveyor belt to clamp and position the two bottle caps before the gasket is installed, preventing the bottle caps from shifting or shaking during installation, ensuring that the gasket accurately enters the inner bottom surface of the bottle cap, and improving installation accuracy and stability.

[0013] Preferably, the end face of the fixing clamp that contacts the bottle cap has two continuously arranged arc-shaped grooves. The arc-shaped groove at the front end of the conveyor is semi-circular, and the central angle of the arc-shaped groove at the rear end of the conveyor is greater than 150° and less than 180°.

[0014] In this preferred embodiment, the fixing clamp is provided with two arc-shaped grooves. The front arc-shaped groove is semi-circular, and the central angle of the rear arc-shaped groove is greater than 150° and less than 180°. This can accommodate the state of two adjacent bottle caps in contact, forming a reliable clamp and positioning for the two bottle caps respectively, preventing the bottle caps from rotating or misaligning during clamping, and further improving the installation accuracy. Since the front end of the bottle cap does not have a contacting bottle cap, the front arc-shaped groove is semi-circular. However, the rear end of the bottle cap does have a contacting bottle cap, so the central angle of the rear arc-shaped groove is greater than 150° and less than 180°. This prevents the rear arc-shaped groove from being inserted between the two bottle caps, avoiding squeezing the two bottle caps in the bottle cap conveying direction.

[0015] Preferably, the detection area further includes two detection probes disposed on the support and located at the front end of the suction cup, with the distance between the two detection probes being the diameter of the bottle cap.

[0016] In this preferred embodiment, the detection probe is mounted on the support and located at the front end of the suction cup. The distance between the two detection probes is the diameter of the bottle cap. The probes can be raised and lowered synchronously with the support, eliminating the need for a separate detection drive mechanism. The structure is compact and can quickly detect whether the bottle cap is in place before the gasket is installed, thus improving the reliability of the system.

[0017] Preferably, the testing area includes a counter located at the top of the bottle cap, a camera located at the front end of the counter, the camera being mounted on a fixed plate, the fixed plate having an elongated hole, and a bolt threadedly connected to a bracket being installed in the elongated hole.

[0018] In use, this preferred solution uses a counter and a camera to count and capture images of bottle caps in the testing area, enabling online inspection of the appearance and size of the gaskets. The camera is mounted on a fixed plate with elongated holes, and its position can be adjusted with bolts to accommodate different bottle cap sizes and testing requirements, thereby improving the flexibility and accuracy of the inspection.

[0019] Preferably, the unloading area is provided with a second cylinder located on one side of the second conveyor belt. The extended end of the second cylinder extends along the width direction of the second conveyor belt and is fixedly connected to a baffle that extends forward at an angle. On the other side of the second conveyor belt, there is a material drop box located directly opposite the baffle and a waste sheet box located at the rear end of the material drop box.

[0020] When this preferred solution is in use, the feeding area, through the second cylinder, the forward-tilting baffle, the dropping box and the waste box, can automatically separate qualified products from unqualified products according to the test results. It has a simple structure, fast operation, and improves sorting efficiency and product yield.

[0021] Preferably, the conveying speed of the second conveyor belt is greater than that of the first conveyor belt.

[0022] In this preferred embodiment, the conveying speed of the second conveyor belt is greater than that of the first conveyor belt, which allows the bottle caps entering the second conveyor belt to be further spaced apart, avoiding interference between adjacent bottle caps and improving the accuracy of counter counting and camera photography.

[0023] A method of using a bottle cap inner gasket mounting system includes the following steps: The feeding device places bottle caps sequentially onto the first conveyor belt with the bottle cap openings facing upwards and adjacent bottle caps in contact. When the bottle caps enter the operating area, the downward movement of the support causes the two detection probes to move downwards. The detection probes contact the inner bottom surface of the bottle caps to detect their presence. Then, under the conveyor belt, the bottle caps are conveyed to the bottom of the suction cup. At this time, the first cylinder drives the fixing clamp to press and fix the bottle caps onto the side frame of the first conveyor belt, and the first conveyor belt stops conveying. Then, while driving the support to move upward, the first rotating shaft is driven to rotate, so that the openings of the two pneumatic suction cups are set upward and inserted into the corresponding material tubes. Then, the pneumatic suction cups are driven to suck air and adsorb the pad into the suction cups. Then, while driving the support to move downward, the first rotating shaft is driven to rotate 180°, so that the suction cups carry the pad downward and insert it into the bottom surface of the bottle cap. The air pump is driven to blow air to put the pad into the bottle cap. The downward movement of the support also drives the pad and the detection probe to move downward, thus completing the actions of the detection probe and the pneumatic suction cups at the same time. Then, the first cylinder is driven to retract, and the first conveyor belt continues to transport the two bottle caps with the gaskets installed, so that the two bottle caps with the gaskets installed enter the inclined channel along the first guide channel. The bottle cap at the front end is pushed into the second conveyor belt by the bottle cap at the rear end, while the bottle cap at the rear end moves to the buffer area. At this time, since the two bottle caps at the rear end are installing gaskets, the first conveyor belt stops transporting. Therefore, the bottle cap at the rear end remains in the buffer area, while the bottle cap at the front end continues to move on the second conveyor belt. Thus, the two bottle caps are separated. Even if there is a certain gap between the two bottle caps, when the first conveyor belt continues to transport, the bottle cap at the rear end is pushed by the first conveyor belt to the second conveyor belt for transport. Bottle caps located on the second conveyor belt enter the testing area, are countered, and then photographed by a camera. The image is uploaded, the appearance and size of the gasket are checked, and the signal is transmitted to the control console. When the test fails, the second cylinder is driven to extend the baffle, which guides the bottle cap into the waste box. When the test passes, the bottle cap enters the discharge box under the guidance of the baffle.

[0024] In this preferred embodiment, both the detection probe and the pneumatic suction cup are mounted on the support. During a single lifting and lowering of the support, the bottle cap placement detection and gasket adsorption / installation are completed simultaneously, resulting in a compact operating cycle and high production efficiency. The inclined guide device and buffer zone separate two simultaneously installed bottle caps, and the speed difference of the second conveyor belt further increases the distance, facilitating subsequent individual detection and sorting. The entire process is highly automated, reducing labor costs and improving production efficiency and product qualification rate. The beneficial effects of this invention are as follows: Through the coordinated operation of the feeding device, the first conveyor belt, the inspection area, the operating area, the inclined guide device, the second conveyor belt, the testing area, and the unloading area, the entire process of automatic feeding, dual-station synchronous installation, online visual inspection, and automatic sorting of qualified and unqualified products for bottle cap gaskets is achieved. This significantly improves production efficiency and product consistency, and reduces labor costs and labor intensity. The operating area adopts a structural design with dual material pipes, dual pneumatic suction cups, and a shared lifting support, enabling the detection probe and suction cup to complete the bottle cap positioning detection and gasket adsorption installation in the same lifting stroke. The action rhythm is compact, and the installation accuracy is high. The fixing clamp and the limiting plate work together to reliably position the bottle cap. The circumferential multi-air port design of the pneumatic suction cup ensures uniform and stable adsorption and release of the gasket, effectively avoiding missed installation and misaligned installation. The inclined guide device combined with the buffer area enables two bottle caps installed at the same time to be automatically separated, and the high conveying speed of the second conveyor belt further widens the gap, creating favorable conditions for subsequent bottle counting, photography, and sorting. The testing area uses counters and adjustable cameras to perform online appearance and size inspections on each bottle cap. The unloading area utilizes retractable baffles in conjunction with a discharge box and a waste box to automatically divert products based on the inspection results, ensuring high product yield. The entire system is compact, stable, and highly adaptable, capable of meeting the gasket installation and inspection needs of bottle caps of different specifications. Attached Figure Description

Detailed Implementation

[0026] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0027] See attached document Figure 1-4 The present invention discloses a bottle cap inner gasket installation system and its usage method. The installation system includes a feeding device 1, a first conveyor belt 2, an inspection area 3, an operation area 4, an inclined guide device 5, a second conveyor belt 6, a testing area 7, and a discharging area 8.

[0028] In this embodiment, the forward direction of the bottle cap along the first conveyor belt 2 and the second conveyor belt 6 is defined as the forward direction.

[0029] The feeding device 1 is located at the starting end of the first conveyor belt 2 and is used to place bottle caps sequentially onto the first conveyor belt 2. The feeding device 1 is existing technology and can be conventional equipment such as a vibratory feeder or a cap sorting machine, which can make the bottle caps face upward and arranged in sequence, with adjacent bottle caps in contact.

[0030] Both sides of the first conveyor belt 2 are provided with limiting plates 21 arranged along its conveying direction. The limiting plates 21 extend along the conveying direction of the first conveyor belt 2 and are used to limit the two sides of the bottle cap. The vertical distance between the two limiting plates is greater than the outer diameter of the bottle cap.

[0031] The first conveyor belt 2 carries the bottle caps sequentially through the inspection area 3 and the operation area 4. The inspection area 3 is located directly above the first conveyor belt 2 and is used to check whether the bottle caps are in place and the condition of the inner cavity of the bottle caps. The operation area 4 is used to simultaneously install two gaskets into two bottle caps respectively.

[0032] The operating area 4 is equipped with a support 13, on which two feed tubes 14 for placing gaskets are mounted. The two feed tubes 14 are arranged along the bottle cap arrangement and conveying direction, i.e., one in front of the other. The diameter of the outlet of the feed tube 14 is smaller than the diameter of the gasket, so the gasket naturally stacks inside the feed tube 14 and will not fall off automatically from the outlet.

[0033] The bracket 13 is also provided with a support 15 that slides along the height direction. The support 15 is installed on the bracket 13 by a vertical guide rail or guide rod and is driven to lift by a cylinder, electric cylinder or other linear drive mechanism.

[0034] Two pneumatic suction cups 17 are rotatably connected to the support 15 via a first rotating shaft 16. The two pneumatic suction cups 17 are arranged along the bottle cap arrangement and conveying direction, and are located directly below the two material tubes 14. The first rotating shaft 16 can be driven by a rotary cylinder or a motor to rotate the pneumatic suction cups 17. The pneumatic suction cups 17 are also provided with several air ports arranged circumferentially, and each air port is connected to an air pump. The suction and blowing of the air pump realizes the adsorption and release of the gasket.

[0035] The support 13 is also equipped with a first cylinder 19 that extends toward the bottle cap. The first cylinder 19 and the support 15 are located on both sides of the first conveyor belt 2, respectively.

[0036] A fixing clamp 20 is fixedly connected to the extended end of the first cylinder 19. A limiting plate 21 on the first conveyor belt 2 cooperates with the fixing clamp 20 to press the bottle cap located directly below the material tube 14, thus achieving positioning and clamping of the bottle cap. Two continuously arranged arc-shaped grooves 22 are formed on the end face of the fixing clamp 20 that contacts the bottle cap. Figure 3 As shown, the arc-shaped groove 22 at the front end of the conveyor is semi-circular, and the central angle of the arc-shaped groove 22 at the rear end of the conveyor is greater than 150° and less than 180°. This design can better adapt to the state of two adjacent bottle caps in contact, so that the fixing clamp 20 can stably clamp the two bottle caps at the same time, while avoiding excessive constraint on the bottle caps and damage to them.

[0037] Two detection probes 23 are also installed on the support 15. The two detection probes 23 are located at the front end of the pneumatic suction cup 17, and the distance between the two detection probes 23 is the diameter of the bottle cap. The detection probes 23 move up and down synchronously with the support 15. The detection probes 23 can be contact sensors, microswitches, or distance sensors. When the detection probes 23 move downward and contact the inner bottom surface of the bottle cap, they can detect whether the bottle cap exists and whether it is in place, and transmit the signal to the control console.

[0038] An inclined guide device 5 is disposed between the first conveyor belt 2 and the second conveyor belt 6. The inclined guide device 5 includes a first guide channel 9 parallel to the first conveyor belt 2, a second guide channel 10 parallel to the second conveyor belt 6, and an inclined channel 11 connecting the first guide channel 9 and the second guide channel 10 and disposed at an angle. The side frames of the first conveyor belt 2 and the second conveyor belt 6 form a buffer area 12 supporting the bottle caps. The buffer area 12 is located between or above the adjacent side frames of the first conveyor belt 2 and the second conveyor belt 6, and is used to temporarily support bottle caps located at the rear end, so that two bottle caps with gaskets installed simultaneously can be separated.

[0039] The second conveyor belt 6 has a higher conveying speed than the first conveyor belt 2. A testing area 7 and a feeding area 8 are sequentially set on the second conveyor belt 6.

[0040] Test area 7 includes a counter 24 and a camera 25. The counter 24 is located directly above the bottle caps and is used to count the passing bottle caps. The camera 25 is located in front of the counter 24 and is used to photograph the bottle caps and the gaskets inside them. The camera 25 is mounted on a mounting plate 26, which has an elongated hole 27. A bolt for threaded connection to a bracket is located within the elongated hole 27. By adjusting the position of the bolt in the elongated hole 27, the mounting height or forward / backward position of the camera 25 can be changed to accommodate different bottle cap sizes and testing requirements.

[0041] The unloading area 8 includes a second cylinder 29, a baffle 30, a discharge box 31, and a waste box 32. The second cylinder 29 is located on one side of the second conveyor belt 6, with its extended end extending along the width of the second conveyor belt 6. The extended end of the second cylinder 29 is fixedly connected to a baffle 30 that extends forward at an angle. On the other side of the second conveyor belt 6, there is a discharge box 31 located directly opposite the baffle 30, and a waste box 32 located at the rear end of the discharge box 31. After the baffle 30 extends, it guides the bottle caps on the second conveyor belt 6 to the discharge box 31 or the waste box 32, thus separating qualified and unqualified products.

[0042] This embodiment also includes a control console, which is electrically connected to the detection probe 23, the first cylinder 19, the drive unit of the first rotating shaft 16, the air pump, the counter 24, the camera 25, the second cylinder 29, the drive motors of the first conveyor belt 2 and the second conveyor belt 6, etc., for coordinating and controlling the actions of each component, and judging whether the appearance and size of the gasket are qualified based on the image captured by the camera 25.

[0043] The method of using the bottle cap inner gasket installation system in this embodiment is as follows: The feeding device 1 places bottle caps sequentially onto the first conveyor belt 2, with the bottle cap openings facing upwards and adjacent bottle caps in contact. The first conveyor belt 2 moves the bottle caps forward, passing through the inspection area 3 for preliminary inspection; When the bottle cap enters the operating area 4, the support 15 moves downward, causing the two detection probes 23 to move downward as well. The detection probes 23 contact the inner bottom surface of the bottle cap to detect its presence. Then, the first conveyor belt 2 continues to convey the bottle cap, bringing it directly below the pneumatic suction cup 17. At this point, the first cylinder 19 drives the fixing clamp 20 to extend. The fixing clamp 20, in conjunction with the limiting plate 21, presses and fixes the two bottle caps onto the side frame of the first conveyor belt 2. Simultaneously, the first conveyor belt 2 stops conveying, keeping the bottle caps directly below the material tube 14. Then, the drive support 15 moves upward, simultaneously driving the first rotating shaft 16 to rotate, causing the openings of the two pneumatic suction cups 17 to face upward and insert into the corresponding material tube 14. Next, the drive pneumatic suction cups 17 suck air, adsorbing the bottommost gasket in the material tube 14 into the suction cup. Subsequently, the drive support 15 moves downward, simultaneously driving the first rotating shaft 16 to rotate 180°, causing the pneumatic suction cups 17 to flip the gasket downward and insert it into the bottom surface of the bottle cap. At this time, the drive air pump blows air, placing the gasket into the bottle cap. Because the downward movement of the support 15 simultaneously moves the gasket and the detection probe 23 downward, the bottle cap detection action of the detection probe 23 and the gasket installation action of the pneumatic suction cups 17 can be completed simultaneously, with a compact action cycle. Then, the first cylinder 19 is driven to retract, causing the retaining clamp 20 to release the bottle cap. The first conveyor belt 2 continues to convey the two bottle caps with the gaskets installed, allowing them to enter the inclined channel 11 along the first guide channel 9. The front bottle cap is pushed onto the second conveyor belt 6 by the rear bottle cap, while the rear bottle cap moves to the buffer area 12. At this time, since the two rear bottle caps are installing gaskets in the operating area 4, the first conveyor belt 2 stops conveying, so the rear bottle cap remains in the buffer area 12; while the front bottle cap continues to move on the second conveyor belt 6, thereby separating the two bottle caps and creating a certain gap between them. When the first conveyor belt 2 continues to convey, the rear bottle cap is pushed onto the second conveyor belt 6 by the first conveyor belt 2 for conveying. Because the conveying speed of the second conveyor belt 6 is greater than that of the first conveyor belt 2, the bottle caps will be further spaced apart on the second conveyor belt 6. After the bottle caps enter the test area 7, they are first counted by the counter 24, and then photographed by the camera 25. The images captured by the camera 25 are uploaded to the control console, which checks whether the appearance and size of the pads meet the requirements. When the inspection fails, the control console drives the second cylinder 29 to extend the baffle 30. Under the guidance of the baffle 30, the unqualified bottle cap enters the waste box 32. When the inspection passes, the bottle cap enters the discharge box 31 under the guidance of the baffle 30, completing the entire gasket installation and inspection sorting process.

[0044] This embodiment, through the combination of the above-described structure and method, achieves automatic installation, online detection, and automatic sorting of the inner gasket of the bottle cap. Two gaskets can be installed simultaneously, resulting in high production efficiency. Furthermore, the bottle caps can be automatically separated and spaced on the second conveyor belt, ensuring accurate and reliable detection and unloading.

[0045] Of course, the above description is not limited to the examples above. Technical features not described in this invention can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solutions of this invention and are not intended to limit this invention.

Those skilled in the art should understand that any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention do not depart from the spirit of this invention and should also fall within the scope of protection of the claims of this invention.

The bottle cap inner gasket installation system according to claim 7, characterized in that: The unloading area (8) is provided with a second cylinder (29) located on one side of the second conveyor belt (6). The extended end of the second cylinder (29) extends along the width direction of the second conveyor belt (6) and is fixedly connected to a baffle (30) that extends forward at an angle. On the other side of the second conveyor belt (6), there is a dropping box (31) located directly opposite the baffle (30) and a waste sheet box located at the rear end of the dropping box (31).

9. The bottle cap inner gasket installation system according to claim 4, characterized in that: The conveying speed of the second conveyor belt (6) is greater than that of the first conveyor belt (2).

10. The method of using the bottle cap inner gasket installation system according to claim 8, characterized in that: The feeding device places the bottle caps sequentially onto the first conveyor belt (2), with the bottle cap opening facing upwards and adjacent bottle caps in contact. When the bottle cap enters the operating area (4), the downward movement of the support (15) causes the two detection probes (23) to move downwards. The detection probes (23) contact the inner bottom surface of the bottle cap to detect its presence. Then, under the conveying of the first conveyor belt (2), the bottle cap enters the lower end of the suction cup. At this time, the first cylinder (19) drives the fixing clamp (20) to press and fix the bottle cap onto the side frame of the first conveyor belt (2), and the first conveyor belt (2) stops conveying. Then, while driving the support (15) to move upward, the first rotating shaft (16) is driven to rotate, so that the openings of the two pneumatic suction cups (17) are set upward and inserted into the corresponding material tube (14). Then, the pneumatic suction cups (17) are driven to suck air and the pad is sucked into the suction cup. Then, while driving the support (15) to move downward, the first rotating shaft (16) is driven to rotate 180°, so that the suction cups drive the pad to insert downward into the bottom surface of the bottle cap, and the air pump is driven to blow air to put the pad into the bottle cap. The downward movement of the support (15) simultaneously drives the pad and the detection probe (23) to move downward, thereby simultaneously completing the actions of the detection probe (23) and the pneumatic suction cups (17). Then the first cylinder (19) is driven to retract, and the first conveyor belt (2) continues to convey, so that the two bottle caps with the gaskets installed enter the inclined channel (11) along the first guide channel (9). The bottle cap at the front end enters the second conveyor belt (6) under the push of the bottle cap at the rear end, while the bottle cap at the rear end moves to the buffer area (12). At this time, since the two bottle caps at the rear end are installing gaskets, the first conveyor belt (2) stops conveying, so the bottle cap at the rear end stays in the buffer area (12), while the bottle cap at the front end continues to move on the second conveyor belt (6). Thus, the two bottle caps are separated. Even if there is a certain gap between the two bottle caps, when the first conveyor belt (2) continues to convey, the bottle cap at the rear end is pushed by the first conveyor belt (2) to the second conveyor belt (6) for conveying. Bottle caps located on the second conveyor belt (6) enter the testing area (7), are countered (24), and then are photographed by the camera (25). The images are uploaded, the appearance and size of the gaskets are checked, and the signal is transmitted to the control console. When the test fails, the second cylinder (29) is driven to extend the baffle (30). Under the guidance of the baffle (30), the bottle caps enter the waste box (32). When the test passes, the bottle caps enter the drop box (31) under the guidance of the baffle (30).
