Description

Technical Field

[0001] This utility model relates to the field of cigarette machinery and equipment technology, and more specifically, to a cigarette classification device after testing on a comprehensive cigarette testing platform. Background Technology

[0002] With the improvement of lean management in the tobacco industry, the physical quality of cigarettes has become increasingly important to enterprises. The quality of cigarette physical indicators is a crucial component of cigarette product quality and is essential for the long-term high-quality development of industrial enterprises. Currently, in actual production processes, cigarette factories mainly focus on physical indicators such as cigarette weight, circumference, length, draw resistance, ventilation rate, and hardness. The comprehensive testing platform, as a commonly used instrument for testing cigarette physical indicators in the industry, can simultaneously measure six indicators: cigarette weight, circumference, length, draw resistance, ventilation rate, and hardness, offering fast testing speed and high sensitivity.

[0003] Currently, the commonly used imported and domestic testing stations in the industry automatically discharge cigarettes after five consecutive modules of testing. All tested cigarettes fall into the same collection box without classifying qualified and unqualified cigarettes, and it is impossible to check unqualified cigarettes, which affects the specific analysis of the reasons for the unqualified samples. At the same time, since the cigarettes are automatically collected into the recycling box, they cannot be checked in the order of collection, making it difficult to match the test data with the actual items, and making re-inspection difficult.

[0004] Therefore, how to provide a cigarette classification device after testing on a comprehensive cigarette testing platform has become a technical problem that urgently needs to be solved in this field. Utility Model Content

The first ends of the two connecting rods are respectively connected to the bottom of the two rotating plates, and the second ends of the two connecting rods are respectively connected to the first arc-shaped plate and the second arc-shaped plate.

[0012] Optionally, the rotating plate is provided with mounting holes;

[0013] The transmission unit also includes a rotating shaft and a fixing block. The fixing block is disposed on both sides of the top of the conveying pipe. The fixing block is provided with a connecting hole. The rotating shaft is inserted into the mounting hole and the connecting hole respectively, and is rotatably connected to the mounting hole and the connecting hole.

[0014] Optionally, the cigarette sorting device after testing on the cigarette comprehensive testing platform further includes an air compression pipe, the first end of which is connected to the discharge hopper, and the second end of which is connected to an external air source.

[0015] Optionally, the collection component includes a first collection box located below the exhaust port for collecting qualified cigarettes.

[0016] Optionally, the collection assembly further includes a second collection box, two slide rails and a fixing rod. The bottom of the second collection box has a connecting sleeve. The slide rails pass through the connecting sleeve and are slidably connected to the connecting sleeve. The inner wall of the second collection box has multiple grooves, which correspond to the second end of the conveying pipe.

[0017] The fixing rods are perpendicularly connected to both ends of the two slide rails to fix the slide rails and the second collection box.

[0018] Optionally, the collection assembly further includes a second drive cylinder, a third drive cylinder, and a slide groove.

The bottom of the transmission unit is rotatably connected to the first and second arc-shaped plates to drive them to rotate, thus opening the exhaust port. The collecting assembly is connected to the second end of the conveying pipe and positioned below the exhaust port. In operation, the integrated testing platform detects qualified and unqualified cigarettes. Driven by airflow, these cigarettes are conveyed from the outlet to the conveying pipe. When a qualified cigarette passes the exhaust port, the first drive cylinder activates, driving the transmission unit to rotate. This, in turn, rotates the first and second arc-shaped plates, opening the exhaust port and allowing the qualified cigarette to be discharged. When an unqualified cigarette passes the exhaust port, the exhaust port remains closed, and the cigarette continues to move to the end of the conveying pipe, falling into the grooves of the second collection box, thus achieving sequential arrangement. The second collection box can move horizontally on a slide rail, aligning the grooves sequentially with the pipe outlet. Once one layer of grooves is filled, the collection box can move downwards to continue receiving subsequent cigarettes, achieving layered stacking and maintaining the cigarette testing order.

[0022] This invention can classify and collect qualified and unqualified cigarettes separately, facilitating subsequent inspection of unqualified cigarettes and specific analysis of the reasons for their unqualification. Furthermore, the collection component can automatically classify and collect unqualified cigarettes in sequence, allowing users to compare the test data with the actual cigarettes, which is beneficial for re-inspection.

[0029] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0030] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0032] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0033] like Figures 1 to 3 As shown in the figure, this utility model embodiment provides a cigarette classification device after testing on a comprehensive cigarette testing platform, including: a discharge hopper 1, a conveying pipe 2, a control component 3, and a collection component 4.

[0034] The top of the discharge hopper 1 is used to connect with the discharge port of the integrated test bench 6, the bottom of the discharge hopper 1 is connected to the first end of the conveying pipe 2, and a smoke exhaust port is provided at the bottom of the center position of the conveying pipe 2.

[0035] The control component 3 includes a first drive cylinder 31, a transmission unit, a first arc-shaped plate 32, and a second arc-shaped plate 33. The first drive cylinder 31 is located outside the conveying pipe 2, and its output shaft is connected to the transmission unit. The first arc-shaped plate 32 and the second arc-shaped plate 33 are located at the exhaust port and coincide with it. The bottom of the transmission unit is rotatably connected to the first arc-shaped plate 32 and the second arc-shaped plate 33 to drive them to rotate, thereby opening the exhaust port. Specifically, the transmission unit is located outside the conveying pipe 2.

[0036] Specifically, the first arc plate 32 and the second arc plate 33 initially coincide with the smoke exhaust port, closing the smoke exhaust port so that the conveying pipe 2 can convey cigarettes. The transmission unit can drive the first arc plate 32 and the second arc plate 33 to rotate to open or close the smoke exhaust port.

[0037] The diameters of the first arc plate 32 and the second arc plate 33 are the same as the inner diameter of the conveying pipe 2, ensuring that the conveying pipe 2 is sealed when closed, allowing the cigarette to pass through smoothly.

[0038] The collecting component 4 is connected to the second end of the conveying pipe 2 and is located below the exhaust port, and is used to separately collect qualified cigarettes and unqualified cigarettes.

[0039] During use, after the comprehensive testing platform 6 detects qualified and unqualified cigarettes, it transports them from the discharge port to the conveying pipeline 2 under the propulsion of airflow.

[0040] When a qualified cigarette passes through the exhaust port, the first drive cylinder 31 is activated, which drives the transmission unit to move, thereby causing the first arc plate 32 and the second arc plate 33 to rotate, so as to open the exhaust port and allow the qualified cigarette to be discharged, and then collected by the collection component 4 located below the exhaust port.

[0041] When an unqualified cigarette passes through the exhaust port, the first drive cylinder 31 does not start, meaning the exhaust port is closed, thus allowing the unqualified cigarette to be directly transported to the collection assembly 4.

[0042] This utility model connects the bottom of the discharge hopper 1 to the first end of the conveying pipe 2, and sets the first driving cylinder 31 outside the conveying pipe 2. The output shaft of the first driving cylinder 31 is connected to the transmission part. The first arc plate 32 and the second arc plate 33 are set at the exhaust port and coincide with the exhaust port. The bottom of the transmission part is rotatably connected to the first arc plate 32 and the second arc plate 33 to drive the first arc plate 32 and the second arc plate 33 to rotate and open the exhaust port. The collecting component 4 is connected to the second end of the conveying pipe 2 and is located below the exhaust port. In use, the integrated testing platform 6 detects qualified and unqualified cigarettes and transports them from the discharge port to the conveying pipe 2. When a qualified cigarette passes through the exhaust port, the first drive cylinder 31 is activated, driving the transmission unit to move, which in turn drives the first arc plate 32 and the second arc plate 33 to rotate, opening the exhaust port and allowing the qualified cigarette to be discharged. When an unqualified cigarette passes through the exhaust port, the exhaust port does not open, and the cigarette is directly transported to the collection component 4. This invention can classify and collect qualified and unqualified cigarettes separately, facilitating subsequent inspection of unqualified cigarettes and specific analysis of their causes. Furthermore, the collection component 4 can also arrange and stack unqualified cigarettes in sequence, effectively avoiding cigarette confusion. This allows users to match the test data with the actual cigarettes, supports quality traceability and re-inspection, and improves quality inspection efficiency and data usability.

[0043] In one embodiment of the cigarette classification device after testing on the cigarette comprehensive testing platform of this utility model, the diameter of the first arc plate 32 and the diameter of the second arc plate 33 are equal to the diameter of the conveying pipe 2.

[0044] Specifically, the length of the first arc plate 32 and the length of the second arc plate 33 are equal to the length of the smoke outlet. When the first arc plate 32 and the second arc plate 33 are fastened together, the two ends of the first arc plate 32 and the two ends of the second arc plate 33 are completely aligned with the conveying pipe 2, so as not to affect the conveying of the cigarettes, ensuring that the conveying pipe 2 is sealed when closed and the cigarettes pass through smoothly.

[0045] Alternatively, the thickness of the first end of the first arc-shaped plate 32 can be less than the thickness of the second end of the first arc-shaped plate 32, and the thickness of the first end of the first arc-shaped plate 32 can be less than the thickness of the conveying pipe 2, while the thickness of the second end of the first arc-shaped plate 32 can be greater than the thickness of the conveying pipe 2. Similarly, the thickness of the first end of the second arc-shaped plate 33 can be less than the thickness of the second end of the second arc-shaped plate 33, and the thickness of the first end of the second arc-shaped plate 33 can be less than the thickness of the conveying pipe 2, while the thickness of the second end of the second arc-shaped plate 33 can be greater than the thickness of the conveying pipe 2.

[0046] The first end of the first arc plate 32 and the first end of the second arc plate 33 are close to the integrated testing platform 6, while the second end of the first arc plate 32 and the second end of the second arc plate 33 are far away from the integrated testing platform 6. Thus, when the first arc plate 32 and the second arc plate 33 are engaged, the first end of the first arc plate 32 and the first end of the second arc plate 33 are lower than the conveying pipe 2, while the second end of the first arc plate 32 and the second end of the second arc plate 33 are higher than the conveying pipe 2, which also ensures that the cigarettes are conveyed normally.

[0047] In one embodiment of the cigarette classification device after testing on the comprehensive cigarette testing platform of this utility model, such as Figure 2 and Figure 3 As shown, the transmission unit includes a connecting plate 34, two rotating plates 35, and two connecting rods 36. Two fixed shafts 37 are respectively provided on both sides of the connecting plate 34. The top of the rotating plate 35 is provided with an oblong hole 38. The fixed shafts 37 are connected to the oblong hole 38 so that the two rotating plates 35 are positioned on both sides of the connecting plate 34. The output shaft of the first driving cylinder 31 is connected to the top of the connecting plate 34. The first ends of the two connecting rods 36 are respectively connected to the bottom of the two rotating plates 35, and the second ends of the two connecting rods 36 are respectively connected to the first arc plate 32 and the second arc plate 33.

[0048] Specifically, when a qualified cigarette passes through the exhaust port, the first drive cylinder 31 is activated, and the first drive cylinder 31 drives the connecting plate 34 to move toward the conveying pipe 2. As the connecting plate 34 presses down, the fixed shafts 37 on both sides of the connecting plate 34 act within the waist-shaped holes 38, thereby causing the two rotating plates 35 to rotate. This causes the two connecting rods 36 to drive the first arc plate 32 and the second arc plate 33 to rotate relative to each other, thereby opening the exhaust port and discharging the qualified cigarette from the exhaust port.

[0049] After a qualified cigarette is discharged from the exhaust port, the first drive cylinder 31 drives the connecting plate 34 to move away from the conveying pipe 2, that is, it drives the connecting plate 34 to move upward, which in turn drives the rotating plate 35 and the connecting rod 36 to move upward, so that the two connecting rods 36 drive the first arc plate 32 and the second arc plate 33 to rotate in opposite directions, thereby sealing the exhaust port. The structure is simple and improves work efficiency.

[0050] In one embodiment of the cigarette classification device after testing on the comprehensive cigarette testing platform of this utility model, such as Figure 2 and Figure 3 As shown, the rotating plate 35 is provided with mounting holes 39.

[0051] The transmission unit also includes a rotating shaft and a fixed block. The fixed block is set on both sides of the top of the conveying pipe 2. The fixed block is provided with a connecting hole. The rotating shaft is inserted into the mounting hole 39 and the connecting hole respectively, and is rotatably connected to the mounting hole 39 and the connecting hole, converting the linear motion of the first drive cylinder 31 into the rotational motion of the two rotating plates 35, thereby driving the first arc plate 32 and the second arc plate 33 to open and close.

[0052] This utility model sets the fixing blocks on both sides of the top of the conveying pipe 2, and inserts the rotating shaft into the mounting hole 39 and the connecting hole respectively, and rotatably connects with the mounting hole 39 and the connecting hole, thereby rotatably installing the rotating plate 35 on the conveying pipe 2, so that the rotating plate 35 can rotate stably under the drive of the connecting plate 34.

[0053] In one embodiment of the cigarette classification device after testing on the comprehensive cigarette testing platform of this utility model, such as Figure 1 As shown, the cigarette classification device after testing on the cigarette comprehensive testing platform also includes an air compression pipe 5. The first end of the air compression pipe 5 is connected to the discharge hopper 1, and the second end of the air compression pipe 5 is connected to an external air source.

[0054] Specifically, the air pressure introduced through the air compression pipe 5 is ≥0.4MPa.

[0055] This invention connects the first end of the air compression pipe 5 to the discharge hopper 1 and the second end of the air compression pipe 5 to an external air source. The air compression pipe 5 introduces air into the conveying pipe 2, and the cigarette moves along the conveying pipe 2 under the drive of compressed air, thereby improving the conveying efficiency.

[0056] In one embodiment of the cigarette classification device after testing on the cigarette comprehensive testing platform of this utility model, the collection component 4 includes a first collection box located below the exhaust port for collecting qualified cigarettes. The collection of qualified cigarettes is achieved through the first collection box, avoiding the problem of qualified cigarettes being scattered or damaged.

[0057] In one embodiment of the cigarette classification device after testing on the comprehensive cigarette testing platform of this utility model, such as Figure 1 As shown, the collection assembly 4 also includes a second collection box 41, two slide rails 42 and a fixing rod 43. The bottom of the second collection box 41 has a connecting sleeve, the slide rails 42 pass through the connecting sleeve and are slidably connected to the connecting sleeve, and the inner wall of the second collection box 41 has a plurality of grooves 44, which correspond to the second end of the conveying pipe 2.

[0058] The fixing rod 43 is perpendicularly connected to both ends of the two slide rails 42 to fix the slide rails 42 and the second collection box 41.

[0059] Specifically, the diameter of the groove 44 is equal to or slightly larger than the diameter of the cigarette.

[0060] When defective cigarettes are conveyed into the first groove 44 of the second collection box 41, the operator acts on the second collection box 41 to move it on the slide rail 42 so that the second groove 44 corresponds to the second end of the conveying pipe 2 until the defective cigarettes fill multiple grooves 44. After the defective cigarettes fill multiple grooves 44, the operator moves the slide rail 42 downward on the fixed rod 43 and aligns the second end of the conveying pipe 2 with the top of the defective cigarettes in the second collection box 41, so that the defective cigarettes conveyed by the conveying pipe 2 can be stacked in the second collection box 41, completing the sequential collection of defective cigarettes.

[0061] In one embodiment of the cigarette sorting device after testing on the cigarette comprehensive testing platform of this utility model, the collection component 4 further includes a second driving cylinder, a third driving cylinder, and a slide groove 45. The slide groove 45 is disposed on the inner wall of the fixed rod 43, and the two ends of the slide rail 42 are slidably disposed in the slide groove 45. The second driving cylinder is connected to the side wall of the second collection box 41 and is used to drive the second collection box 41 to move left and right. The third driving cylinder is disposed in the slide groove 45 and is connected to the slide rail 42 and is used to drive the slide rail 42 to move up and down.

[0062] This invention features a sliding groove 45 mounted on the inner wall of a fixed rod 43, with both ends of a slide rail 42 slidably mounted within the groove 45. By connecting a second drive cylinder to the side wall of a second collection box 41, the second collection box 41 can be driven to move left and right. A third drive cylinder is mounted within the groove 45 and connected to the slide rail 42 to drive the slide rail 42 to move up and down, thereby adjusting the position of the second collection box 41. This facilitates the stacking of substandard cigarettes within the second collection box 41, effectively improving the collection efficiency of substandard cigarettes.

[0063] In one embodiment of the cigarette classification device after testing on the cigarette comprehensive testing platform of this utility model, the collection component 4 further includes a controller, a first detector and a second detector. The first detector is set at the second end of the conveying pipe 2, and the second detector is located on the inner wall of the second collection box 41. The controller is electrically connected to the second driving cylinder, the third driving cylinder, the first detector and the second detector respectively.

[0064] Specifically, when the first detector detects a cigarette moving out of the second end of the conveying pipe 2, it transmits a signal to the controller. The controller then activates the second drive cylinder, which in turn moves the second collection box 41, aligning the second end of the conveying pipe 2 with the next second groove 44. When the second detector detects a cigarette, indicating that a layer is full, it transmits a signal to the controller. The controller then activates the third drive cylinder, which moves the slide rail 42, causing the second collection box 41 to move. This aligns the second end of the conveying pipe 2 with the top of any unqualified cigarettes in the second collection box 41. Through the horizontal movement of the second collection box 41, each groove 44 is sequentially aligned with the outlet of the conveying pipe 2, achieving a sequential arrangement of cigarettes. Once a layer of grooves 44 is filled, the second collection box 41 can move downwards to continue receiving subsequent cigarettes, forming a layered stack and maintaining the cigarette detection order. This effectively improves the intelligence of the cigarette sorting device after testing on the cigarette comprehensive testing platform of this invention.

[0065] Furthermore, the controller is also electrically connected to the first drive cylinder 31. When the comprehensive test bench 6 detects a qualified cigarette, it transmits a signal to the controller, which then controls the first drive cylinder 31 to start and open the exhaust port.

[0066] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
