Description

Technical Field

[0001] This invention relates to the field of physical quantity technology of cigarettes and filter rods, specifically to a fully automatic comprehensive testing platform for cigarettes and filter rods. Background Technology

[0002] The physical parameters of cigarettes and filter rods are of great importance to both the production and use of cigarettes. The State Administration for Quality Supervision, Inspection and Quarantine and the Standardization Administration of China have formulated a series of conditions and standards for tobacco production and testing, with key indicators including weight, circumference, length, draw resistance, ventilation rate, and hardness.

[0003] The weight, circumference, and length of cigarettes and filter rods play a crucial role in stabilizing the production process of packaging machines. The length of cigarettes and filter rods is typically measured using GB / T 22838.2-2009, "Determination of Physical Properties of Cigarettes and Filter Rods—Part 2: Length Photoelectric Method." The cigarette or filter rod is placed at the measurement position, and a parallel light beam is shone onto its end. The end of the cigarette or filter rod is projected or scanned, and the length value is provided by a photoelectric receiving device and data processing system. The draw resistance and ventilation rate of cigarette products are the most direct, sensitive, and fundamental indicators affecting the smoking experience for consumers. Excessive draw resistance makes the cigarette difficult to smoke, while insufficient draw resistance results in thin smoke, thus affecting the sensory quality of the cigarette product. Simultaneously, the draw resistance and ventilation rate of cigarettes also provide important data support for reducing the tar and nicotine content in cigarette smoke. The hardness of cigarettes and filter rods is closely related to their weight and draw resistance, directly affecting the quality and efficiency of cigarette and filter rod assembly, and consequently the sensory quality of the cigarette product. The hardness of cigarettes and filter rods is typically measured according to GB / T 22838.6-2009 "Determination of Physical Properties of Cigarettes and Filter Rods—Part 6: Hardness," which defines hardness as the percentage of the sample's diameter after radial compression relative to its initial diameter, given a certain pressure applied within a specific time period. The measuring instrument is a device capable of applying radial pressure to the sample, with a pressure head diameter of 12±0.01mm, a pre-pressure of no more than 0.196N, a pre-compression time of 1±0.5s, a compression speed of 0.55±0.05mm / s, a compression load of 2.94±0.01N, and a compression time of 15±1s. The test area of ​​the sample pressure baffle must have a rectangular plane of at least 20mm x 20mm.

[0004] Currently, manufacturers typically use a comprehensive testing platform to test the above-mentioned indicators for cigarettes and filter rods. The comprehensive testing platform includes modules such as a feeding module, a weight detection module, a circumference and length detection module, a suction resistance detection module, and a hardness detection module. Among these issues, the feeding module of most integrated testing platforms suffers from problems such as scattered and difficult-to-clean tobacco shreds, and the inconvenience of removing cigarettes when they become stuck, making it difficult to observe the situation. When testing the weight of cigarettes and filter rods, the weighing balance needs to be horizontal, and most testing platforms on the market use adjustment modules or instruments, which are inconvenient and cumbersome to operate. When testing the length of cigarettes and filter rods, the module needs to be calibrated first. However, the standard requires a standard rod with a diameter of 8mm and a length of 150mm. Because this rod is made of heavy metals such as stainless steel, it is much heavier than cigarettes and filter rods. During calibration, the reference surface of the pressing and receiving parts will differ from the reference surface when actually testing the cigarette, thus affecting the accuracy of the length measurement. The suction resistance detection module of the integrated testing platform cannot automatically test the condition of the latex tube, and there is a problem of tobacco shreds accumulating inside. In the hardness detection module of the integrated testing platform, most use a horizontal pressure method with an air-float supported pressure head, that is, using air flotation to support the vertical pressure of the pressure head, applying pressure vertically to the sample in the horizontal direction. This pressure application method can reduce the edge friction of the pressure head through the air flotation device and control the pressure application speed and time to a certain extent. However, during the measurement process, as the air flotation device moves up and down, the pressure head will slowly rotate along its own central axis under the action of the air buoyancy force. In addition, the laser rangefinder that detects the displacement of the pressure head reflects the light onto the metal surface in a long strip shape. Therefore, after a period of measurement, the position of the laser rangefinder reflecting the light onto the pressure head is completely different from the initial measurement position, resulting in significant differences in the measurement results. After the cigarette and filter rod testing is completed, the comprehensive testing platform on the market usually has a recycling basket to collect the samples directly. However, such rough recycling cannot link the samples with the data one by one, which is not conducive to the discovery of subsequent process problems and the improvement of process parameters.

This application integrates components such as a weight detection unit, a circumference detection unit, and a suction resistance detection unit into the testing frame, using modular detection units to inspect the appearance of cigarettes. However, this application still lacks functions such as cigarette classification and sample traceability, and its measurement accuracy is also low, failing to solve the aforementioned problems.

[0006] Utility model patent application CN201716091U discloses a device for detecting five physical indicators of cigarettes. This application integrates five detection units: weight, circumference, length, draw resistance, and ventilation rate, offering rich functionality and the ability to simultaneously detect these five indicators. However, this application lacks functions such as cigarette classification and sample traceability, and its measurement accuracy is not high, failing to address the aforementioned problems.

[0112] Compared with the prior art, the beneficial effects of the present invention are:

[0113] (1) In the circumference and length detection module of the present invention, after the sample completes the detection of the two physical quantities of circumference and length and falls into the next detection module, the upper air block and the lower air block will be connected to the air source to blow away impurities such as tobacco on the rotating clamp and the reference block, so as to ensure that the reference contact between the lower end face of the sample remains unchanged during circumference and length detection, and at the same time reduce the influence of impurities on the circumference measuring instrument and the length measuring instrument, thereby improving the accuracy and repeatability of circumference and length detection.

[0114] (2) The circumference and length detection module of the present invention is designed to support the reference block of the sample and the standard bar to be measured. By connecting the linear guide module, it resists the impact brought by the measurement of the high-quality standard bar, and ensures that the reference surface of the reference block remains unchanged when measuring the length of items of different masses, thereby greatly improving the accuracy, repeatability and consistency of length detection.

[0115] (3) The hardness testing module of the present invention uses the point contact action of the inclined block installed on the air float and the square step of the pre-pressure column when the pressure linear slide rises, so that the pre-pressure weight will not rotate after a period of measurement, ensuring that the initial measurement position does not change. At the same time, the lower end of the inclined block is closer to the central axis of the air float bushing than the upper end, so that from the pre-pressure state to the end of the pressure state, the inclined block and the square step of the pre-pressure column can be guaranteed to be non-contact throughout the entire process, thereby greatly improving the accuracy, repeatability and consistency of hardness testing.

[0116] (4) When the hardness testing module of the present invention is running, it will use the method of the pressure linear slide to first descend and then rise, and use the conical cylinder at the upper end of the pre-pressure weight and the conical groove corresponding to the pressure weight to achieve automatic alignment of the center, ensuring that the gravity of the pressure weight is evenly distributed around the central axis of the pre-pressure column, thereby improving the stability of the structure and the accuracy of the hardness measurement results.

[0117] (5) The parts such as the feeding block, hopper main board, movable sealing plate, and rear sealing plate in the split hopper unit of the present invention are all made of transparent material, which makes it easy to observe the state of the sample in the feeding module. The movable sealing plate is designed as a pull-out structure, which makes it easy to remove the cigarette without the aid of tools when the cigarette is stuck, which is simple and convenient.

[0118] (6) The middle hollow groove of the upper baffle of this feeding module is used so that the groove diameter of the tobacco end face is larger than the groove diameter of the filter end face, which can greatly reduce the situation of tobacco jamming in the feeding module, improve detection efficiency, and reduce the frequency of failure.

[0119] (7) The feeding module is also equipped with a tobacco receiving box at the bottom, which can effectively catch the tobacco falling during the feeding process and can be pulled out and cleaned when it is full. It is simple and convenient, reduces the interference of disorderly falling tobacco on the detection of each module, and improves the accuracy and stability of detection.

[0120] (8) Before testing the sample, the suction resistance detection module of the present invention will draw part of the probe cavity through a vacuum generator to form a negative pressure, and judge whether the latex tube used to cover the sample is damaged by the stability of the negative pressure, which improves the accuracy of the suction resistance measurement results, reduces manual experience judgment, and eliminates the need to manually disassemble the probe to check the condition of the latex tube, saving time and effort.

[0121] (9) After the sample is detected and falls into the next detection module, the suction resistance detection module of the present invention will open the corresponding solenoid valve switch, allowing compressed air to enter the probe cavity through the lower sliding block, thereby blowing away impurities such as tobacco inside the cavity and improving the accuracy and repeatability of the measurement results.

[0122] (10) The weighing balance of this weight detection module is equipped with an independent leveling mechanism. The leveling state of the weighing balance can be adjusted by rotating the four corner moving leveling units. No tools are needed. The structure is simple and easy to operate, which can improve the accuracy of weight detection.

[0123] (11) The sorting and collection module of the present invention receives samples that do not require hardness testing and samples that require hardness testing by setting up a hardness-untested collection box and a sorting collection box, respectively. At the same time, the sorting guide unit automatically sorts the tested samples into the qualified or unqualified areas of the sorting collection box, performing preliminary differentiation of the samples, which is convenient for subsequent operation by employees and saves time and effort.

[0124] (12) This invention has a sample traceability function. The inkjet printing system is integrated into the hardness detection module. Without affecting the hardness measurement, the push block can push the sample at a uniform speed to the bottom of the inkjet printer. The inkjet printer nozzle sprays powder onto the surface of the sample to be tested to form a barcode, so that the test data can form a one-to-one correspondence with the sample. The sample can be traced and analyzed in the later data processing, which is convenient for process optimization and improvement. At the same time, the inkjet printing system can be selected to run in the control program to meet the needs of different users.

[0125] (13) The air-bearing bushing of the hardness testing module of the present invention is made of graphite. Graphite has good chemical stability, high thermal conductivity, small linear expansion coefficient and good lubricity. Under the combined action of compressed air, the pre-pressure weight can achieve "zero friction" and the deformation in the later stage is small, which can well ensure the accuracy of the pre-pressure and applied pressure required for measuring hardness.

[0126] (14) The chassis of the present invention adopts an integrated sheet metal appearance design, which is beautiful and elegant, and has high stability. The circuit module adopts a total control system and a sub-control system to optimize transmission efficiency and stability. Each detection unit adopts a modular design, which is convenient for installation, maintenance and replacement, improves usage efficiency and saves labor costs.

[0127] (15) The present invention suspends the printer in the center of the left side of the chassis, which is ergonomic and convenient for testers to operate. It is also equipped with a manual air gun for manually blowing away dust and other impurities. The top of the chassis is equipped with a three-color status indicator light so that the instrument's operating status can be observed at any time. Attached Figure Description

Detailed Implementation

[0179] To facilitate understanding of the technical solution of the present invention by those skilled in the art, the technical solution of the present invention will now be further described in conjunction with the accompanying drawings.

[0180] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0181] See Figure 1 and Figure 2 This embodiment discloses a fully automatic cigarette and filter rod integrated testing platform, including a chassis 1000, a feeding module 2000, a weight detection module 3000, a circumference and length detection module 4000, a suction resistance detection module 5000, a hardness detection module 6000, and a sorting and collection module 7000.

[0182] Chassis 1000

[0183] like Figure 1 As shown, the chassis 1000 is a long rectangular frame structure made of sheet metal, serving as the main frame of the integrated test bench. It features an integrated sheet metal exterior design, which is aesthetically pleasing and offers high stability.

[0184] The left side wall of the chassis 1000 is equipped with, from top to bottom, a touchscreen 1100, a printer 1300, and a manual air gun 1400. The installation of these devices on the left side of the chassis 1000 is ergonomic and facilitates operation by testing personnel. The touchscreen 1100 is fixedly mounted on the upper part of the left side wall of the chassis 1000 via a touchscreen bracket 1200, used to display relevant data and for operator use. The printer 1300 is fixedly mounted in the middle of the left side wall of the chassis 1000 for printing data. The manual air gun 1400 is mounted on the lower part of the left side wall of the chassis 1000, allowing operators to manually blow away tobacco, dust, and other impurities.

[0185] The top of the chassis 1000 is equipped with a status indicator light 1500, which can display different colors to indicate the status of the device. Operators can monitor the operating status of the integrated test bench at any time based on the status indicator light 1500.

[0186] The front of the chassis 1000 is equipped with a switch door 1600. The middle of the switch door 1600 is made of transparent material, which makes it easy for staff to observe the operation of the integrated test bench.

[0187] The chassis 1000 is also equipped with casters 1700 at the four corners of the bottom to facilitate the movement of the entire integrated test bench.

[0188] Feeding module 2000

[0189] The feeding module 2000 is installed inside the chassis 1000, and the upper end of the feeding module 2000 protrudes above the chassis 1000 to facilitate the staff to put in the cigarettes to be tested.

[0190] See Figure 3 The feeding module 2000 includes a feeding base plate 2100, a positioning base plate 2200, a hopper limiting block 2300, a split hopper unit 2400, a tobacco receiving box 2500, and a feeding drive unit 2600.

[0191] The feeding module 2000 is fixed to the housing via the feeding base plate 2100. A positioning base plate 2200 is installed on the upper end of the feeding base plate 2100, and two positioning pins 2210 are fixed to the upper end of the positioning base plate 2200 with screws. Two symmetrically arranged hopper limiting blocks 2300 are fixed to both sides of the upper end of the feeding base plate 2100, and the two hopper limiting blocks 2300 are symmetrically arranged relative to the positioning base plate 2200. A top-to-bottom sliding groove is provided on the opposite side of the two hopper limiting blocks 2300. The two ends of the split hopper unit 2400 are slidably installed in the two hopper limiting blocks 2300 via the sliding groove, and the bottom of the hopper base plate 2410 of the split hopper unit 2400 is guided and positioned by the positioning pins 2210. Finally, the split hopper unit 2400 is fixed with bolts. The split hopper unit 2400 can be detached by plugging and unplugging.

[0192] The tobacco receiving box 2500 is installed on the upper end of the feeding base plate 2100 and located below the split hopper unit 2400, and is used to receive and collect the tobacco falling from the split hopper unit 2400. The tobacco receiving box 2500 is a movable structure and can be automatically pulled out for cleaning after it is full of tobacco.

[0193] See Figures 4 to 7 The split hopper unit 2400 includes a hopper bottom plate 2410, a left sealing plate 2420, a right sealing plate 2430, a rear sealing plate 2440, a movable sealing plate 2450, an upper baffle 2460, a lower movable block 2470, a hopper main plate 2480, and a discharge block 2490.

[0194] The left sealing plate 2420 is installed on the upper left side of the hopper bottom plate 2410, the right sealing plate 2430 is installed on the upper right side of the hopper bottom plate 2410, and the hopper main plate 2480 is installed in the upper middle part of the hopper bottom plate 2410, with both ends of the hopper main plate 2480 connected to the left sealing plate 2420 and the right sealing plate 2430 respectively by screws; the rear sealing plate 2440 is installed at the rear end of the hopper main plate 2480, and a U-shaped groove is opened at the upper end, with the movable sealing plate 2450 slidingly installed in the U-shaped groove; the lower movable block 24... The upper baffle 2460 is slidably mounted on the front end of the hopper main board 2480, and is fixedly mounted on the front end of the hopper main board 2480. The upper baffle 2460 is located above the lower movable block 2470. The upper end of the lower movable block 2470 has a sloping structure, and the upper baffle 2460 is a metal part with a pointed top and a flat bottom. A long, hollowed-out groove 2461 for passing cigarettes is opened on the front. Cigarettes are placed in by pressing the tobacco end face against the right side. The diameter of the right side opening of the long, hollowed-out groove 2461 is larger than the diameter of the left side opening. Since the tobacco end face of the cigarette may be flattened, which may cause cigarette jamming, this greatly reduces the occurrence of cigarette jamming in the feeding module 2000, improves detection efficiency, and reduces the failure frequency.

[0195] The left side of the feed hopper main board 2480 has an arc-shaped groove for cigarette feeding, and the right side has a channel for tobacco shreds to fall. When a cigarette falls into the feed main board from the right side of the long hollow groove 2461 of the upper baffle 2460, if there are tobacco shreds on the end face of the cigarette, they will fall into the tobacco receiving box 2500 through the right channel after entering the feed main board; after the horizontal cigarette passes through the arc-shaped groove, it falls vertically from the bottom of the feed module 2000 into the weight detection module 3000 with the cigarette filter facing down.

[0196] In this embodiment, the hopper bottom plate 2410 has a positioning hole 2411, a tobacco falling channel 2412, and a cigarette falling channel 2413. The positioning hole 2411 is installed in the middle of the hopper bottom plate 2410, the tobacco falling channel 2412 is installed on the right side of the hopper bottom plate 2410, and the cigarette falling channel 2413 is installed on the left side of the hopper bottom plate 2410.

[0197] See Figure 8 The feeding drive unit 2600 includes a feeding motor bracket 2650, a vertical guide rail 2620, a feeding slider 2630, a lower movable block connecting shaft 2640, a feeding motor 2650, and a rotating block 2660.

[0198] The feeding motor bracket 2650 is mounted on the feeding base plate 2100. The feeding motor bracket 2650 has a vertical plate, and two parallel vertical guide rails 2620 are respectively provided at both ends of one side of the vertical plate. The feeding slider 2630 is slidably mounted on the vertical guide rails 2620. The feeding slider 2630 has a horizontal guide groove. The feeding motor 2650 is fixedly mounted on the feeding motor bracket 2650. The output shaft of the feeding motor 2650 is connected to one end of the rotating block 2660. The other end of the rotating block 2660 is installed in the guide groove.

[0199] The rear sealing plate 2440 and the hopper main plate 2480 are provided with vertical sliding grooves for the lower movable block connecting shaft 2640 to pass through. One end of the lower movable block connecting shaft 2640 is connected to the feed slider 2630, and the other end is connected to the lower movable block 2470 after passing through the vertical sliding groove.

[0200] The rotating block 2660 is controlled to rotate around the end connected to the feeding motor 2650 by controlling the feeding motor 2650. The other end of the rotating block 2660 slides in the guide groove on one side and drives the feeding slider 2630 to move on the vertical guide rail 2620 on the other side, so that the lower movable block connecting shaft 2640 can move up and down, thereby driving the lower movable block 2470 to slide up and down.

[0201] In this embodiment, the feeding block 2490 is installed at the front end of the lower movable block 2470 and is made of transparent plexiglass for easy observation. The feeding block 2490 has a downward-sloping funnel structure, which facilitates the automatic falling of cigarettes into the lower part.

[0202] In this embodiment, the hopper main board 2480 is made of transparent plexiglass, allowing observation of the cigarette and filter rod operating status on the back of the hopper main board 2480.

[0203] In this embodiment, the feeding block 2490, hopper main board 2480, movable sealing plate 2450, rear sealing plate 2440 and other parts are all made of transparent material, which makes it easy to observe the state of the sample in the feeding module 2000. The movable sealing plate 2450 is designed as a pull-out structure, which makes it easy to remove the cigarette without the aid of tools when the cigarette is stuck, which is simple and convenient.

[0204] In this embodiment, a material feeding cover plate 2491 is also provided at the upper end of the material feeding block 2490 to cover the material feeding block 2490 and prevent dust and other impurities from falling into the material feeding block 2490.

[0205] The elongated perforated groove 2461 on the upper stop block, with a groove diameter larger than that on the filter tip end face, greatly reduces the likelihood of tobacco jamming in the feeding module 2000, improving detection efficiency and reducing the frequency of failures. The included tobacco receiving box 2500 effectively catches the tobacco falling during feeding and can be easily removed and cleaned when full, simplifying the process and reducing interference from disorderly falling tobacco on the detection of various modules, thus improving the accuracy and stability of the detection.

[0206] Weight detection module 3000

[0207] The weight detection module 3000 is installed inside the chassis 1000 and is located below the feeding module 2000.

[0208] See Figure 9 and Figure 10 The weight detection module 3000 includes a weight base plate 3100, a level adjustment unit 3200, a balance base plate 3300, a weighing balance 3400, a balance connecting rod 3500, a weighing column 3600, a weighing support block 3700, and a support block rotation unit 3800.

[0209] The weight detection module 3000 is installed inside the chassis 1000 via the weight base plate 3100.

[0210] A leveling unit 3200 is installed at each of the four ends of the weight base plate 3100. A balance base plate 3300 is located above the weight base plate 3100, and each of the four ends of the balance base plate 3300 is connected to the leveling unit 3200. The leveling unit 3200 can be freely adjusted up and down, thereby adjusting the levelness of the balance base plate 3300. A weighing balance 3400 is installed on the balance base plate 3300.

[0211] The weighing column 3600 is placed vertically at the front end inside the housing 1000, below the discharge port of the feeding module 2000. The upper end of the weighing column 3600 is connected to the weighing balance 3400 via a balance connecting rod 3500. The weighing support block 3700 is rotatably mounted on its lower end. The support block rotating unit 3800 is mounted on the lower end of the weight base plate 3100 and connected to the weighing support block 3700.

[0212] See Figure 11 and Figure 12The horizontal adjustment unit 3200 includes a stepped stud 3210, a bearing 3220, a long nut 3230, and an adjusting stop 3240. The stepped stud 3210 has three progressively larger steps, with the bottom step (3211) having the largest diameter, the middle step (3212) having the smaller diameter, and the top step (3213) having the smallest diameter. Both the top step (3213) and the middle step (3212) have externally threaded cylinders of different diameters. The bearing 3220 is embedded in the four corners of the weight base plate 3100. After the stepped stud 3210 passes through the inner hole of the bearing 3220, the long nut 3230 tightens the stepped stud 3210 into the inner ring of the bearing 3220 by engaging with the upper step 3213 of the stepped stud 3210 through the thread engagement, thereby fixing the stepped stud 3210 to the weight base plate 3100 and allowing it to rotate in the bearing 3220.

[0213] The balance base plate 3300 is located above the long nut 3230. The four corners of the balance base plate 3300 are provided with through internal threads that mate with the external threads of the upper step 3213 of the stepped stud 3210. The upper step 3213 of the stepped stud 3210 is connected to the balance base plate 3300 by thread engagement, and part of the upper end of the upper step 3213 extends out of the balance base plate 3300. The adjusting baffle can be tightened by engaging with the thread of the upper step 3213 of the stepped stud 3210. The adjusting baffle is used to limit the adjustment of the stepped stud 3210 and prevent the stepped stud 3210 from disengaging from the balance base plate 3300.

[0214] When the level of the weighing balance 3400 located on the base plate 3300 is tilted, causing the weight detection module 3000 to measure inaccurately, the level adjustment unit 3200 provided in this embodiment can adjust the level of the weighing balance 3400 by rotating the four movable stepped studs 3210. No tools are needed, the structure is simple, the operation is convenient, and the accuracy of weight detection can be improved.

[0215] The upper end of the weighing balance 3400 is also equipped with a balance limiting block 3900; used to limit the upward movement distance of the balance connector and prevent damage to the weight detection module 3000.

[0216] The weighing column 3600 is a hollow columnar structure. The sample to be tested falls vertically into the weighing column 3600 from the feeding module 2000, and the weighing support block 3700 provides support for the sample. This allows for the measurement of the weight of the sample.

[0217] The weighing support block 3700 has a U-shaped structure and is rotatably mounted on the bottom of the weighing column 3600 via two U-shaped feet. A crossbar at the bottom supports the sample to be tested. Vertical buffer grooves 3710 are provided on the two U-shaped feet. The support block rotation unit 3800 can control the rotation of the weighing support block 3700 by connecting to the buffer grooves 3710, thereby enabling the support or disabling of the sample to be tested.

[0218] Specifically, the support rotation unit includes a support drive motor 3810, a support rotation disk 3820, and a support connecting column 3830. The support rotation disk 3820 has an elliptical structure. The support drive motor 3810 is mounted on the bottom of the weight base plate 3100. The output shaft of the support drive motor 3810 is connected to one focal point of the support rotation disk 3820. The support connecting column 3830 is mounted on the side of the support rotation disk 3820 away from the support drive motor 3810. One end of the support connecting column 3830 is mounted on the other focal point of the support rotation disk 3820, and the other end is mounted in the buffer groove 3710.

[0219] See Figure 13 and Figure 14 The support rotation unit drives the support rotating disk 3820 to rotate via the support drive motor 3810, which in turn drives the support connecting column 3830 to rotate. The rotation of the support connecting column 3830 enables the weighing support block 3700 to rotate. The buffer groove 3710 of the weighing support block 3700 can prevent the impact of the gravity of the falling cigarettes on the support rotation unit, and also facilitate the rotation of the weighing support block 3700 by the support rotation unit. The support rotation unit controls the position of the weighing support block 3700 via the support drive motor 3810, thereby allowing the measured sample to flow into the circumference and length detection module 4000.

[0220] Circumference and Length Detection Module 4000

[0221] The circumference and length detection module 4000 is installed inside the chassis 1000 and is located below the weight detection module 3000.

[0222] See Figures 15 to 18 The circumference and length detection module 4000 includes a measuring frame 4100, a support reference unit 4200, a horizontal drive unit 4300, a rotary clamp 4400, a rotary drive unit 4500, an upper air block 4600, a lower air block 4700, a length measuring instrument 4800, and a circumference measuring instrument 4900.

[0223] The measuring frame 4100 includes a main base plate 4110, a measuring base plate 4120, a measuring support plate 4130, and a measuring guide column 4140. The measuring base plate 4120 is arranged parallel above the main base plate 4110, and the main base plate 4110 and the measuring base plate 4120 are connected by the measuring support plate 4130.

[0224] The measuring guide column 4140 is installed on the measuring base plate 4120 and located below the discharge port of the weight detection module 3000 to guide the vertical fall of the sample to be tested.

[0225] The rotary clamp 4400, the upper air block 4600, the length measuring instrument 4800, and the circumference measuring instrument 4900 are all mounted on the measuring base plate 4120. The rotary clamp 4400 is located below the measuring guide column 4140, and the upper air block 4600 is located behind the rotary clamp 4400. The upper air block 4600 has a row of fine air holes on the side near the rotary clamp 4400. The air holes are connected to the air supply equipment and can be used to blow away tobacco and other debris from the upper surface of the rotary clamp 4400 to ensure the accuracy of the circumference measurement.

[0226] Two circumference measuring instruments 4900 and two length measuring instruments 4800 are provided. The circumference measuring instruments 4900 and the length measuring instruments 4800 are cross-mounted around the rotary clamp 4400, and the two circumference measuring instruments 4900 and the two length measuring instruments 4800 are symmetrically mounted, respectively, for measuring the circumference and length of the sample to be tested.

[0227] The rotary drive unit 4500 is mounted under the measuring base plate 4120. The rotary drive unit 4500 is connected to the rotary clamp 4400 to control whether the rotary clamp 4400 clamps or does not clamp the sample to be tested.

[0228] See Figure 19 The support reference unit 4200, the horizontal drive unit 4300 and the downward blowing block 4700 are all fixedly installed on the main base plate 4110; the downward blowing block 4700 is installed below the rotary clamp 4400; the horizontal drive unit 4300 is connected to the support reference unit 4200 to drive the support reference unit 4200 to move horizontally, and to support the sample to be tested.

[0229] See Figure 20 The support reference unit 4200 includes a support base plate 4210, a reference block 4220, a reference connecting block 4230, a linear guide rail 4240, and a sliding connecting block 4250.

[0230] A support base plate 4210 is mounted on a main base plate 4110. A linear guide rail 4240 is fixedly mounted on the support base plate 4210. A sliding connecting block 4250 is slidably mounted on the linear guide rail 4240. A reference block 4220 is located above the support base plate 4210, and its side plate is connected to the sliding connecting block 4250. A reference connecting block 4230 is mounted at the rear end of the reference block 4220, and the reference block 4220 is connected to the horizontal drive unit 4300 through the reference connecting block 4230. Specifically, the reference block 4220 has multiple reference surfaces of different heights, arranged in a stepped manner from high to low. The reference surfaces of different heights can accommodate cigarettes of various heights. For cigarettes of different heights, the corresponding reference surface is pushed to the position supporting the cigarette.

[0231] In this embodiment, the reference block 4220, which is used to support the test sample and the standard bar, is designed to withstand the impact brought by the measurement of the high-quality standard bar by connecting the linear guide rail 4240 and the sliding connecting block 4250. This ensures that the reference surface of the reference block 4220 remains unchanged when measuring the length of items of different masses, thereby greatly improving the accuracy, repeatability and consistency of length detection.

[0232] The horizontal drive unit 4300 is located behind the supporting reference unit 4200. The horizontal drive unit 4300 includes a guide connecting block 4310, a guide shaft 4320, a linear bearing 4330, a stop bracket 4340, and a stop cylinder 4350. The reference connecting block 4230 is connected to the stop cylinder 4350 via the guide shaft 4320 and the linear bearing 4330. The stop cylinder 4350 is mounted on the stop bracket 4340.

[0233] The stop cylinder 4350 can drive the reference block 4220 to move horizontally along the trajectory of the linear guide rail 4240 through the guide connecting block 4310 and the guide shaft 4320, thereby controlling which reference surface is used to support the test sample.

[0234] The lower air block 4700 is installed on the support base plate 4210. The lower air block 4700 has multiple waist-shaped grooves on one side that correspond one-to-one with multiple reference surfaces on the reference block 4220. The waist-shaped grooves are connected to the air blowing mechanism. After air is supplied, it can blow away tobacco and other debris on the reference block 4220 to ensure the accuracy of the reference when measuring circumference and length.

[0235] In this embodiment, the down-blowing block 4700 has a front stop 4710, which is installed in front of the support reference unit 4200 to limit the movement of the reference block 4220.

[0236] See Figure 21The rotary drive unit 4500 includes a first rotary synchronous pulley 4510, a rotary synchronous belt 4520, a second rotary synchronous pulley 4530, and a rotary drive motor 4540. The first rotary synchronous pulley 4510 is mounted on the lower end of the measuring base plate 4120 and connected to the rotary clamp 4400. Rotation of the first rotary synchronous pulley 4510 causes the rotary clamp 4400 to clamp or not clamp the cigarette. The second rotary synchronous pulley 4530 is mounted behind the first rotary synchronous pulley 4510 and connected to it via the rotary synchronous belt 4520. The rotary drive motor 4540 is connected to the second rotary synchronous pulley 4530 and drives its rotation.

[0237] The rotation of the second rotary drive synchronous pulley is controlled by the rotary drive motor 4540, which in turn drives the rotation of the first rotary synchronous pulley 4510 by the rotary synchronous belt 4520, thereby controlling the rotary clamp 4400 to clamp or not clamp the sample to be tested.

[0238] See Figure 22 In this embodiment, after the sample completes the detection of the two physical quantities of circumference and length and falls into the next detection module, the upper air block 4600 and the lower air block 4700 will be connected to the air source 5806 to blow away impurities such as tobacco on the rotating clamp 4400 and the reference block 4220. This ensures that the reference contacted by the lower end face of the sample remains unchanged during circumference and length detection, while reducing the influence of impurities on the circumference measuring instrument 4900 and the length measuring instrument 4800, thereby improving the accuracy and repeatability of circumference and length detection.

[0239] 5000 suction resistance detection module

[0240] The suction resistance detection module 5000 is installed inside the chassis 1000 and is located below the circumference and length detection module 4000.

[0241] See Figures 24 to 26 The suction resistance detection module 5000 includes a probe base plate 5100, a probe base 5200, a lower sliding unit 5300, a middle sliding unit 5400, an upper sliding unit 5500, a probe sealing unit 5600, and a needle cylinder 5700.

[0242] The suction resistance detection module 5000 is mounted inside the chassis 1000 via the probe base plate 5100. The probe base 5200 is mounted on the probe base plate 5100, and a negative pressure detection hole is provided inside the probe base 5200. A needle cylinder 5700 is mounted on one side of the probe base 5200, and the piston rod of the needle cylinder 5700 can extend into the probe base 5200 to catch falling samples.

[0243] The lower sliding unit 5300 includes a lower sliding block 5310 and a lower clamping block 5320; the middle sliding unit 5400 includes a middle sliding block 5410 and a middle clamping block 5420; and the upper sliding unit 5500 includes an upper sliding block 5510 and an upper clamping block 5520.

[0244] The lower sliding block 5310 is slidably nested inside the upper end of the probe base 5200. The lower clamping block 5320 is installed at the bottom of the lower sliding block 5310, and the lower clamping block 5320 is covered with a latex tube. The lower sliding block 5310 has a tobacco blowing hole inside.

[0245] The middle sliding block 5410 is slidably nested inside the upper end of the lower sliding block 5310, and the middle clamping block 5420 is fixedly installed at the bottom of the middle sliding block 5410. The middle clamping block 5420 is covered with a latex tube.

[0246] The upper sliding block 5510 is slidably nested inside the upper end of the middle sliding block 5410, and the upper clamping block 5520 is fixedly installed at the bottom of the upper sliding block 5510. The upper clamping block 5520 is covered with a latex tube.

[0247] The probe sealing unit 5600 includes a probe sealing block 5610 and a telescopic cylinder 5620.

[0248] The probe base 5200 has a concave first wedge-shaped portion 5210 at its bottom, and the probe sealing block 5610 has a second wedge-shaped portion 5611 on one side that fits into the first wedge-shaped portion 5210 of the probe base 5200. The second wedge-shaped portion 5611 of the probe sealing block 5610 can seal the bottom of the probe base 5200 by engaging with the first wedge-shaped portion 5210. Specifically, the second wedge-shaped portion 5611 is also provided with an annular sealing ring to ensure a good seal and guarantee the accuracy of the adsorption detection module.

[0249] The telescopic cylinder 5620 is mounted on the probe base plate 5100 and located behind the probe sealing block 5610. The piston rod of the telescopic cylinder 5620 is connected to the probe sealing block 5610. By controlling the telescopic cylinder 5620, it is possible to control whether the probe sealing block 5610 seals the bottom of the probe base 5200.

[0250] Before testing the sample, the suction resistance detection module 5000 of this embodiment uses a vacuum generator 5801 to evacuate part of the probe cavity to create a negative pressure. By analyzing the stability of the negative pressure, it automatically determines whether the latex tube used to cover the sample is damaged, thus improving the accuracy of the suction resistance measurement results, reducing manual judgment, and eliminating the need to manually disassemble the probe to check the condition of the latex tube, saving time and effort.

[0251] See Figure 27The suction resistance detection module 5000 also includes a gas path unit 5800, which includes a vacuum generator 5801, a digital display negative pressure gauge 5802, a first differential pressure sensor 5803, a second differential pressure sensor 5804, a valve island 5805, a gas source 5806, a laminar flow element, a CFO (standard flow orifice), and solenoid valves MV1, MV2, MV3, MV4, MV5, MV6, MV7, MV8, MV9, MV10, MV11, MV12, MV13, and MV14.

[0252] The upper clamping block 5520 and the lower clamping block 5320 are both connected to the outlet of the vacuum generator 5801 through solenoid valves MV3 and MV4, respectively. The middle clamping block 5420 is connected to the outlet of the vacuum generator 5801 through solenoid valve MV4. The outlet of the vacuum generator 5801 is also connected to the bottom of the suction resistance detection device through CFO and solenoid valve MV5. A digital negative pressure gauge 5802 is also installed at the outlet of the vacuum generator 5801.

[0253] The air inlet of valve island 5805 is connected to air source 5806; and valve island 5805 has three air outlets. One air outlet is connected to the air inlet of vacuum generator 5801 through solenoid valve MV12, one air outlet is connected to telescopic cylinder 5620 through solenoid valve MV13, and one air outlet is connected to needle cylinder 5700 through solenoid valve MV14.

[0254] The gas source 5806 is also connected to the lower sliding block 5310 via the solenoid valve MV11.

[0255] The lower sliding block 5310 is connected to the laminar flow element through the solenoid valve MV9, and is connected to the atmosphere through the solenoid valve MV10; the middle sliding block 5410 is connected to the laminar flow element through the solenoid valve MV8, and is connected to the atmosphere through the solenoid valve MV7; a first differential pressure sensor 5803 is also provided at the laminar flow element.

[0256] The pneumatic circuit unit 5800 is also equipped with an external detection point, which is connected to the bottom of the lower slider through the solenoid valve MV6. A second differential pressure sensor 5804 is also installed at the external detection point to monitor the pressure value of the suction resistance detection module 5000.

[0257] It also includes a detection unit and a calibration unit. Both the detection unit and the calibration unit are connected to the vacuum generator 5801 via solenoid valves MV1, MV5 and CFO respectively; and are connected to external detection points via solenoid valves MV2 and MV6 respectively.

[0258] The detection and calibration sections are connected to the vacuum generator 5801 via solenoid valve MV5 and to an external detection point via solenoid valve MV6, enabling the detection and calibration of the gas path. By switching solenoid valves MV1 and MV2, the connection between the detection or calibration section and that part of the gas path can be controlled, thereby achieving the detection or calibration of the gas path.

[0259] It should be noted that all of the above solenoid valves are two-position three-way solenoid valves.

[0260] Before the sample enters the suction resistance detection module 5000, solenoid valve MV12 opens, vacuum generator 5801 starts working, and controls solenoid valves MV5 and MV6 to close, while solenoid valves MV3 and MV4 open. Vacuum generator 5801 connects with the probe chambers of the three pipes: lower clamp 5320, middle clamp 5420, and upper clamp 5520, creating a negative pressure inside. If there is no leakage, the negative pressure will stabilize, and the digital negative pressure gauge 5802 at vacuum generator 5801 will maintain a relatively stable range. This is used to detect whether there is a leak in the latex tubing covering the lower clamp 5320, middle clamp 5420, and upper clamp 5520. If there is no leakage, the suction resistance detection module 5000 is functioning normally. Then, solenoid valve MV14 opens, needle cylinder 5700 starts, and the piston rod of needle cylinder 5700 pops out.

[0261] After the sample enters the suction resistance detection module 5000, it will remain at the upper end of the needle cylinder 5700 due to the constraint of the piston rod. The latex tubing on the lower clamping block 5320, middle clamping block 5420, and upper clamping block 5520 covers the surface of the sample. Solenoid valves MV5 and MV6 open, creating a stable airflow of 17.5 mL / s in the tubing under the combined action of the CFO and vacuum generator 5801. The differential pressure sensor operates, transmitting the collected data to the sub-control system, which in turn transmits the data to the main control system. After data processing, the corresponding suction resistance and ventilation rate values ​​are displayed on the monitor. Once data acquisition is complete, the control solenoid valve MV14 closes, the needle cylinder 5700 shuts down, and the piston rod of the needle cylinder 5700 retracts, allowing the sample to fall into the hardness detection module 6000 below.

[0262] After the sample to be tested falls, control solenoid valves MV5, MV6, MV7, MV8, MV9, and MV10 close, while solenoid valve MV11 opens. Air source 5806 connects to the detection chamber of suction resistance detection module 5000. Compressed air from air source 5806 enters the detection chamber through sliding block 5310, blowing away impurities such as tobacco. In this embodiment, after the sample to be tested completes detection and falls into the next detection module, suction resistance detection module 5000 opens the solenoid valve switch, allowing compressed air to enter the probe cavity through sliding block 5310, thereby blowing away impurities such as tobacco inside the cavity and improving the accuracy and repeatability of the measurement results.

[0263] Hardness testing module 6000

[0264] The hardness testing module 6000 is installed inside the chassis 1000 and is located below the suction resistance testing module 5000.

[0265] See Figures 28 to 30 The hardness testing module 6000 includes a hardness support 6100, a rotating receiving unit 6200, a pushing unit 6300, a hardness pressure application unit 6400, and a coding machine 6500.

[0266] The hardness bracket 6100 includes a hardness base plate 6110 and a hardness vertical plate 6120, with the hardness vertical plate 6120 vertically mounted on the hardness base plate 6110. The rotating receiving unit 6200, the pushing unit 6300, the hardness applying unit 6400, and the inkjet printer 6500 are all mounted inside the chassis 1000 via the hardness bracket 6100.

[0267] See Figures 31 to 33 The rotating receiving unit 6200 includes a rotating cylinder 6210, a rotating connector 6220, and a receiving cylinder 6230.

[0268] A rotary cylinder 6210 is mounted on the hardness vertical plate 6120 of the hardness support 6100 and is located behind the hardness vertical plate 6120. The output shaft of the rotary cylinder 6210 extends from the rear of the hardness vertical plate 6120. A rotary connector 6220 is located in front of the hardness vertical plate 6120, and one end of the rotary connector 6220 is connected to the output shaft of the rotary cylinder 6210. A receiving cylinder 6230 is mounted on the other end of the rotary connector 6220.

[0269] The interior of the receiving cylinder 6230 has a receiving hole 6231 with one end open, used to receive the sample to be tested falling from the suction resistance detection module 5000 located above. The front end of the receiving cylinder 6230 has a through groove 6232 that communicates with the receiving hole 6231 inside the receiving cylinder 6230.

[0270] The initial state of the rotating connector 6220 is that the end with the receiving cylinder 6230 is at the lower end, and the receiving cylinder 6230 is in a horizontal position. When it is necessary to receive a sample, the rotary cylinder 6210 is activated, thereby driving the rotating connector 6220 to rotate around the axis of the output shaft of the rotary cylinder 6210. This allows the receiving cylinder 6230 to rotate from a horizontal position to a vertical position, with the open end facing upwards and aligned with the output port of the suction resistance detection module 5000 to receive the sample. After receiving the sample, the rotary cylinder 6210 is reversed, causing the receiving cylinder 6230 to return to a horizontal position. In this embodiment, the right side of the receiving cylinder 6230 is an open structure, and the counterclockwise rotation of the rotating connector 6220 causes the receiving cylinder 6230 to rotate to a vertical position on the right side to receive the sample.

[0271] The pushing unit 6300 includes a horizontal slide 6310, a push drive 6320, and a push block 6330. The horizontal slide 6310 is fixedly installed on the bottom of the hardened base plate 6110. The push drive 6320 is installed on the hardened base plate 6110 and connected to the horizontal slide 6310 to drive the horizontal slide 6310 to slide. The push block 6330 is fixedly installed on the slider of the horizontal slide 6310. When the push drive 6320 is activated, it drives the slide to slide horizontally left and right, thereby causing the push block 6330 to slide horizontally.

[0272] The push block 6330 has a C-shaped structure. The bottom extension 6331 of the push block 6330 is connected to the slider of the horizontal slide 6310. The top extension 6332 of the push block 6330 is located above the hardness base plate 6110. When the receiving cylinder 6230 is in a horizontal state at the bottom, the stroke of the top extension 6332 of the push block can pass through the through groove 6232 of the receiving cylinder 6230 and through the receiving hole 6231 of the receiving cylinder 6230, thereby pushing the sample to be tested in the receiving cylinder 6230 onto the hardness application unit 6400.

[0273] See Figures 34 to 36 The hardness application unit 6400 is mounted on the hardness base plate 6110 and located to the right of the rotating support unit 6200. The hardness application unit 6400 includes a pressure support 6410, a slide drive assembly 6430, a pressure slide assembly 6420, an air-bearing pressure assembly 6440, a laser rangefinder sensor 6450, a pressure plate 6460, a pressure push plate 6470, a pressure baffle 6480, and a hardness blowing block 6490.

[0274] The pressure-applying bracket 6410 includes a pressure-applying base plate 6411, support plates 6412, and a motor mounting plate 6413. The pressure-applying base plate 6411 serves as the base platform for the hardness-applying unit 6400 and is fixedly mounted on the hardness-applying base plate 6411. Two support plates 6412 are vertically mounted on the upper ends of the pressure-applying base plate 6411, and are symmetrically arranged relative to the pressure-applying base plate 6411. The two ends of the motor mounting plate 6413 are respectively mounted on the upper ends of the two support plates 6412.

[0275] The pressure slide assembly 6420 includes a slide mounting plate 6421 and a pressure linear slide 6422. The slide mounting plate 6421 is mounted between support plates 6412, and the pressure linear slide 6422 is vertically slidably mounted on the front end of the slide mounting plate 6421.

[0276] The slide drive assembly 6430 includes a pressure stepper motor 6431, a first pressure synchronous pulley 6432, a second pressure synchronous pulley 6433, and a pressure synchronous belt 6434. The pressure stepper motor 6431 is mounted at the bottom center of the motor mounting plate 6413, with its output shaft extending above the motor mounting plate 6413. The first pressure synchronous pulley 6432 is connected to the output shaft of the pressure stepper motor 6431. The second pressure synchronous pulley 6433 is mounted on the upper end of the pressure linear slide 6422 and fixed to the axis of rotation of the pressure linear slide 6422 by set screws. The pressure synchronous belt 6434 is installed between the first and second pressure synchronous pulleys 6432 and is in a tensioned state.

[0277] When the pressure-applying stepper motor 6431 is started, its output shaft drives the first pressure-applying synchronous pulley 6432 to rotate. This, in turn, drives the second pressure-applying synchronous pulley 6433 to rotate via the pressure-applying synchronous belt 6434. This, in turn, causes the pressure-applying linear slide 6422 to slide vertically up and down, allowing the air-bearing pressure assembly 6440 mounted on the linear slide 6422 to slide up and down. This provides power for the vertical movement of the air-bearing pressure assembly 6440.

[0278] The air flotation pressure application assembly 6440 includes an air flotation mounting plate 6441, an air flotation block 6442, an inclined block 6443, a pre-pressure column 6444, a pre-pressure plug 6445, an air flotation bushing 6446, and a pressure application weight 6447. The air flotation pressure application assembly 6440 is externally covered by a cover plate to prevent dust or tobacco residue, thus improving measurement accuracy.

[0279] The air flotation mounting plate 6441 is vertically mounted on the moving part at the front end of the pressure linear slide 6422. The air flotation block 6442 is mounted on the bottom front end of the air flotation mounting plate 6441. The upper end of the air flotation block 6442 is provided with an irregular groove, the upper end of which is rectangular and the lower end is columnar, and the upper and lower ends are connected.

[0280] The air-bearing bushing 6446 is a hollow cylinder made of graphite, and it is embedded and bonded to the lower columnar groove of the irregular groove.

[0281] The inclined block 6443 is installed in the upper rectangular groove of the irregular groove. The plane of the inclined block 6443 facing the central axis of the air bearing sleeve 6446 is not perpendicular to the horizontal plane at the bottom of the upper rectangular groove of the air bearing block 6442. In the straight line mapped on the plane of the inclined block 6443 by the vertical plane passing through the central axis of the air bearing sleeve 6446, the distance between the lower end of the inclined block 6443 and the central axis of the air bearing sleeve 6446 is shorter than that between the upper end.

[0282] The upper end of the preload column 6444 is a conical cylinder, the middle part is a square step, and the lower end is a cylinder. The lower cylindrical end of the preload column 6444 passes through the air-bearing bushing 6446 and can move up and down under the action of external force.

[0283] One side wall of the square step of the pre-compression column 6444 faces the inclined block 6443. Since the lower end of the inclined block 6443 is shorter than its upper end from the central axis, the distance between the side wall of the square step of the pre-compression column 6444 and the inclined block 6443 gradually decreases during the descent of the pre-compression column 6444. As the pre-compression column 6444 falls, the inclined block 6443 ensures that the position of the pre-compression column 6444 remains consistent, preventing the rotation of the pre-compression column 6444 from causing different measurement positions each time. This ensures that the position of the pre-compression column 6444 remains consistent in every measurement, improving the measurement accuracy of the laser rangefinder 6450. Furthermore, during measurement, the pre-compression column 6444 moves upward relative to the inclined block 6443. The structure of the inclined block 6443 ensures that from the pre-compression state to the end of the compression state, the square step of the inclined block 6443 and the pre-compression column 6444 remain completely non-contact, thereby greatly improving the accuracy, repeatability, and consistency of hardness testing.

[0284] The pre-compression plug 6445 is a cylindrical structure with the same diameter as the lower cylinder of the pre-compression column 6444, and is bonded to the bottom of the pre-compression column 6444. The pre-compression column 6444 and the pre-compression plug 6445 together form a single piece, which serves as the pre-compression weight.

[0285] The pressure weight 6447 is located above the pre-pressure weight. The pressure weight 6447 has a central opening with an inverted conical groove at the top, a columnar structure in the middle, and a conical groove at the bottom. This conical groove can cooperate with the conical cylinder at the top of the pre-pressure plug 6445, thereby ensuring the fixed relative position of the pressure weight 6447 when applying pressure to the pre-pressure weight.

[0286] The laser rangefinder 6450 is installed on the upper end of the pressure weight 6447 and can measure the falling distance of the top of the pre-pressure weight through the opening in the middle of the pressure weight 6447, thereby determining the hardness of the sample to be tested.

[0287] The pressure plate 6460 is fixedly installed on the pressure base plate 6411, and is located directly below the air flotation pressure assembly 6440. The pressure plate 6460 has a long rectangular structure, is horizontally arranged, and has a guide groove at the upper end. When the receiving cylinder 6230 is in the initial position at the lower end, it can be considered that the guide groove and the receiving hole 6231 of the receiving cylinder 6230 are on the same straight line. The pushing block 6330 can push the sample to be tested in the receiving cylinder 6230 onto the pressure plate 6460.

[0288] The pressure plate 6460, located at the upper center below the air flotation pressure assembly 6440, has a horizontal surface for supporting the sample to be tested, which is slightly higher than the bottom of the guide channel. The sample to be tested can be pushed onto the horizontal surface and kept horizontal, and the guide channel can also limit the sliding of the sample to be tested.

[0289] The pressure pusher plate 6470 is installed behind the pressure plate 6460. After the sample to be tested completes the hardness measurement or inkjet printing operation, the pressure pusher plate 6470 pushes the sample to be tested on the pressure plate 6460 into the sorting and collection module 7000 below.

[0290] The pressure baffle 6480 is installed in front of the pressure plate 6460 to prevent the sample to be tested from flying out.

[0291] The hardness blowing block 6490 is installed behind the pressure plate 6460. The side of the hardness blowing block 6490 facing the pressure plate 6460 has a row of fine blowing holes. After air is introduced, it can blow away impurities such as tobacco on the pressure plate 6460.

[0292] The inkjet printer 6500 is installed on one side of the air flotation pressure assembly 6440 and is located above the pressure plate 6460. The push block 6330 can also push the sample to be tested below the inkjet printer 6500. After the inkjet printer 6500 is powered on, it can use powder to form a traceable barcode on the surface of the sample to be tested.

[0293] See Figures 37 to 39Before the sample enters the hardness testing module 6000, the pressure stepper motor 6431 starts, driving the pressure linear slide 6422 downwards. When the pre-pressure plug 6445 contacts the pressure plate 6460 and supports the pressure weight 6447 to detach from the upper end of the air float block 6442, the pressure stepper motor 6431 stops, and the pressure linear slide 6422 stops moving. At this time, through the cooperation of the conical cylinder at the upper end of the pre-pressure column 6444 and the conical groove at the lower end of the pressure weight 6447, the pressure weight 6447 can automatically adjust to be concentric with the pre-pressure column 6444. Then, the pressure stepper motor 6431 is started again, controlling the pressure linear slide 6422 to rise to a certain height and then stop. At this time, the pressure weight 6447 falls back onto the air float block 6442, and the square step of the pre-pressure column 6444 falls on the end face of the air float sleeve 6446. This is the initial measurement position.

[0294] After the sample to be tested enters the hardness testing module 6000, the receiving cylinder 6230 is in a vertical position to receive the sample. Then, the rotating cylinder 6210 drives the receiving cylinder 6230 from a vertical position to a horizontal position. Under the action of the horizontal slide 6310, the pushing block 6330 pushes the sample to be tested onto the pressure plate 6460, which is located on the horizontal surface directly below the air flotation pressure module. Subsequently, the pressure stepper motor 6431 drives the pressure linear slide 6422 downward. When the pre-pressure plug 6445 contacts the sample to be tested, and the square step of the pre-pressure column 6444 disengages from the air flotation bushing 6446 and does not contact the pressure weight 6447, the pressure linear slide 6422 stops moving and remains in this position for a period of time. This is the pre-pressure measurement position.

[0295] The pressure stepper motor 6431 drives the pressure linear slide 6422 to continue to descend. After the pre-pressure weight supports the pressure weight 6447 and detaches from the air float block 6442, the pressure linear slide 6422 stops moving and remains for a period of time. This is the full pressure measurement position.

[0296] The linear slide 6422 is pressed up to the initial measurement position. The laser rangefinder 6450 transmits the data to the sub-control system in real time. The sub-control system transmits the data to the main control system. After the data is processed, the corresponding hardness value is displayed on the monitor.

[0297] Under the action of the horizontal slide table 6310, the pusher block 6330 pushes the sample to be tested at a constant speed past the inkjet printer 6500. After the inkjet printer 6500 nozzle sprays powder onto the surface of the sample to form a barcode, the pressure pusher plate 6470 pushes the sample to be tested into the sorting and collection module 7000. At the same time, the hardness blowing block 6490 is connected to the air source 5806 to blow away impurities such as tobacco on the pressure baffle 6480.

[0298] In this embodiment, the hardness testing module 6000 utilizes the point contact between the inclined block 6443 mounted on the air float 6442 and the square step of the pre-pressure column 6444 as the linear slide 6422 rises during the pressure application. This prevents the pre-pressure weight from rotating after a period of measurement, ensuring that the initial measurement position remains unchanged. Simultaneously, the lower end of the inclined block 6443 is closer to the central axis of the air float sleeve 6446 than the upper end, ensuring that there is no contact between the inclined block 6443 and the square step of the pre-pressure column 6444 throughout the entire process from the pre-pressure state to the end of the pressure application state. This greatly improves the accuracy, repeatability, and consistency of hardness testing.

[0299] In this embodiment, the hardness testing module 6000 operates by first lowering and then raising the pressure linear slide 6422. It utilizes the conical cylinder at the upper end of the pre-pressure weight and the corresponding conical groove of the pressure weight 6447 to achieve automatic alignment of the center, ensuring that the gravity of the pressure weight 6447 is evenly distributed around the central axis of the pre-pressure column 6444, thereby improving the stability of the structure and the accuracy of the hardness measurement results.

[0300] The air-bearing bushing 6446 of this hardness testing module 6000 is made of graphite. Graphite has excellent chemical stability, high thermal conductivity, low linear expansion coefficient, and good lubricity. Under the combined action of compressed air, it can make the pre-pressure weight achieve "zero friction" and has small deformation in the later stage, which can well ensure the accuracy of the pre-pressure and applied pressure required for measuring hardness.

[0301] Sorting and collection module 7000

[0302] The sorting and collection module 7000 is installed inside the chassis 1000 and is located below the hardness detection module 6000.

[0303] See Figures 40 to 42 The sorting and collection module 7000 includes a sorting base plate 7100, a hardness-untested collection box 7200, a sorting and collection box 7300, an isolation vertical plate 7400, and a sorting guide unit 7500.

[0304] The sorting and collection module 7000 is fixedly installed inside the chassis 1000 via the sorting base plate 7100. The untested hardness collection box 7200 is movably installed on the upper left side of the sorting base plate 7100. The opening of the untested hardness collection box 7200 is aligned with the outlet of the suction resistance detection module 5000 and is used to collect samples that do not require hardness testing.

[0305] The sorting collection box 7300 is movably installed on the upper right side of the sorting base plate 7100, and the sorting collection box 7300 and the hardness untested collection box 7200 are arranged adjacent to each other. The opening of the sorting collection box 7300 is aligned with the outlet of the hardness testing module 6000, and is used to collect the test samples that have undergone the above-mentioned multiple physical quantity tests.

[0306] In this embodiment, both the untested hardness collection box 7200 and the sorting collection box 7300 are rectangular frame structures. An isolation vertical plate 7400 is provided above the adjacent side of the untested hardness collection box 7200 and the sorting collection box 7300 to prevent the falling test sample from jumping into the other collection box and causing mixing of the test samples.

[0307] Meanwhile, both the untested hardness collection box 7200 and the sorting collection box 7300 have recessed lifting handles at the front bottom, making it convenient for staff to pull out the corresponding collection box from the box to collect the tested samples.

[0308] The sorting and collecting box 7300 in this embodiment also has a vertically placed partition plate 7310, which divides the sorting and collecting box 7300 into two collection areas: the front collection area is used to collect defective products, and the rear collection area is used to collect qualified products. Since there are fewer defective products than qualified products, the front collection area is set to be smaller.

[0309] The sorting guide unit 7500 is installed above the partition plate 7310. The sorting guide unit 7500 includes a sorting base 7510, a miniature rotary cylinder 7520, a left connecting block 7530, a steering plate 7540, a right connecting block 7550, and a sorting fixing block 7560.

[0310] The sorting base 7510 is installed on the upper left side of the sorting collection box 7300. A miniature rotary cylinder 7520 is installed on the left side of the sorting base 7510, and a left connecting block 7530 is installed on the right side of the sorting base 7510. The miniature rotary cylinder 7520 is connected to the left connecting block 7530 and, through the left connecting block 7530, to one side of the steering plate 7540. The sorting fixing block 7560 is installed inside the right side of the box, and a right connecting block 7550 is installed to the left of the sorting fixing block 7560 and connected to the other side of the steering plate 7540. The steering plate 7540 can swing under the action of the miniature rotary cylinder 7520 to complete the screening of the samples to be tested.

[0311] Before the sample falls into the sorting and collection module 7000, the main control system determines whether the sample is qualified based on the detected data. It then rotates the steering plate 7540 to the corresponding angle using a miniature rotary cylinder 7520. After falling, the sample passes through the steering plate 7540 and enters either the qualified or unqualified area of ​​the sorting and collection box 7300. Specifically, when the sample is determined to be qualified, the miniature rotary cylinder 7520 tilts the steering plate 7540 towards the rear, guiding the sample to the rear collection area of ​​the sorting and collection box 7300 (qualified area) during its descent. When the sample is determined to be unqualified, the miniature rotary cylinder 7520 tilts the steering plate 7540 towards the front, guiding the sample to the front collection area of ​​the sorting and collection box 7300 (unqualified area) during its descent.

[0312] This sorting and collection module 7000 can use the turning plate 7540 to automatically sort the tested samples into the qualified or unqualified area of ​​the sorting and collection box 7300, and perform preliminary separation of the samples, which is convenient for employees to operate later and saves time and effort.

[0313] See Figure 43 This integrated testing platform includes a main control system, a feeding control system, a weight detection control system, a circumference and length detection control system, a suction resistance detection control system, a hardness detection control system, and a sorting and collection control system.

[0314] The feeding control system includes a first sample sensor, which is connected to the main control system.

[0315] The weight detection and control system includes a first sub-control system, a weighing balance 3400, and a second sample sensor; the weighing balance 3400 and the second sample sensor are respectively connected to one end of the first sub-control system, and the other end of the first sub-control system is connected to the main control system.

[0316] The circumference and length detection control system includes a second sub-control system, a circumference measuring instrument 4900, a length measuring instrument 4800, and a third sample detection sensor; the circumference measuring instrument 4900 and the length measuring instrument 4800 are both connected to the second sub-control system through the measuring instrument controller, and the third sample sensor is connected to the second sub-control system; the other end of the second sub-control system is connected to the main control system.

[0317] The suction resistance detection and control system includes a third sub-control system, a differential pressure sensor, and a fourth sample detection sensor; the pressure sensor and the fourth sample detection sensor are respectively connected to one end of the third sub-control system, and the other end of the third sub-control system is connected to the main control system.

[0318] The hardness testing and control system includes a fourth sub-control system, a laser rangefinder 6450, an inkjet printer 6500, and a fifth sample detection sensor. The laser rangefinder 6450 is connected to one end of the fourth sub-control system via an amplifier, the inkjet printer 6500 is connected to one end of the fourth sub-control system via an inkjet controller, the fifth sample detection sensor is connected to one end of the fourth sub-control system, and the other end of the fourth sub-control system is connected to the main control system.

[0319] When the entire integrated test bench is working, the first sample detection sensor at the bottom of the feeding module 2000 detects whether a sample to be tested has fallen. When the sample falls into the weight detection module 3000, it sends a signal to the main control system, which assigns a number to the sample to be tested.

[0320] The weight of the sample to be tested is measured in the weight detection module 3000 by the weighing balance 3400, and the data is sent to the main control system through the first sub-control system and stored after the assigned number.

[0321] Subsequently, the second sample detection sensor at the bottom of the weight detection module 3000 monitors the sample falling to the circumference and length detection module 4000 and sends the data to the main control system via the first sub-control system.

[0322] After the circumference measuring instrument 4900 and the length measuring instrument 4800 in the circumference and length detection module 4000 detect the sample to be tested, the corresponding circumference and length measurement data are input to the second sub-control system through the measuring instrument controller, and then input to the main control system through the second sub-control system, and stored after the above-assigned number.

[0323] Subsequently, the third sample detection sensor at the bottom of the circumference and length detection module 4000 monitors the sample falling to the suction resistance detection module 5000 and sends the data to the main control system via the second sub-control system.

[0324] After the differential pressure sensor in the suction resistance detection module 5000 detects the sample to be tested, it sends the corresponding suction resistance detection data to the main control system through the third sub-control system and stores it after the assigned number.

[0325] Subsequently, the fourth sample detection sensor at the bottom of the suction resistance detection module 5000 monitors the sample falling to the hardness detection module 6000 and sends the data to the main control system via the third sub-control system.

[0326] After the laser rangefinder 6450 in the hardness testing module 6000 detects the sample to be tested, the test data is processed by the amplifier and sent to the main control system through the fourth sub-control system and stored in the assigned number.

[0327] The main control system stores the data, along with the measured physical quantities—weight, circumference, length, suction resistance, and hardness—and displays it on the screen. Simultaneously, the main control system sends data to the inkjet printer controller via the fourth sub-control system. The inkjet printer controller sets the inkjet printing parameters and controls the 6500 nozzle to spray powder onto the surface of the sample to form a barcode. This establishes a one-to-one correspondence between the measured data of the aforementioned physical quantities and the inkjet-printed sample.

[0328] This testing station features sample traceability. An inkjet coding system is integrated into the hardness testing module 6000. Without affecting hardness measurement, the pusher block 6330 can uniformly push the sample below the inkjet printer 6500. The inkjet printer 6500 sprays powder onto the surface of the sample to form a barcode, enabling a one-to-one correspondence between the test data and the sample. This allows for sample traceability and analysis during later data processing, facilitating process optimization and improvement. Furthermore, the inkjet coding system can be selected for operation within the control program to meet the needs of different users.

[0329] The specific implementation steps of the fully automatic cigarette and filter rod comprehensive testing platform, as shown in the attached diagram, are as follows:

[0330] Step 1: Connect the air source 5806, press the switch button, the integrated test bench is powered on and started, the display screen lights up, the status indicator light 1500 works, each unit module self-tests and returns to the starting position, set the test parameters, the staff grabs the sample to be tested and places it into the feeding block 2490 of the feeding module 2000, and then clicks the "Run" button on the display.

[0331] Step 2: The feeding module 2000 starts running. The sample to be tested falls into the hollow groove of the upper baffle 2460. As the upper baffle 2460 moves upward, the sample to be tested changes from horizontal to vertical after passing through the hopper main board 2480. Under the action of gravity, it falls to the weight detection module 3000.

[0332] Step 3: After the sample to be tested enters the weight detection module 3000, it stops on the weighing column 3600. After the weighing balance 3400 weighs the sample, it transmits the data to the sub-control system. The sub-control system transmits the data to the main control system. After the data is processed, the corresponding weight value is displayed on the monitor. The sample to be tested falls to the circumference and length detection module 4000.

[0333] Step 4: After the sample to be tested enters the circumference and length detection module 4000, it stops on the telescopic block. The rotary clamp 4400 closes, the rotary motor runs, and the rotary clamp 4400 drives the sample to be tested to rotate one revolution. At the same time, the circumference measuring instrument 4900 and the length measuring instrument 4800 collect data and send it to the measuring instrument controller. The measuring instrument controller processes the data and transmits it to the sub-control system. The sub-control system transmits the data to the main control system. After the data is processed, the corresponding circumference value and length value are displayed on the display. The sample to be tested falls to the suction resistance detection module 5000. At the same time, the upper air block 4600 and the lower air block 4700 are connected to the air source 5806 to blow away impurities such as tobacco on the telescopic block and the rotary clamp 4400.

[0334] Step 5: The detection process of the sample under test in the 5000 absorption resistance detection module is as follows:

[0335] (1) Before the sample to be tested enters the suction resistance detection module 5000, the solenoid valve MV12 opens, the vacuum generator 5801 starts working, and the control solenoid valves MV5 and MV6 close, while the control solenoid valves MV3 and MV4 open. The vacuum generator 5801 is connected to the probe cavity of the three pipes of the lower clamping block 5320, the middle clamping block 5420, and the upper clamping block 5520, creating a negative pressure inside. If there is no leakage, the negative pressure will tend to stabilize, and the digital negative pressure gauge 5802 at the vacuum generator 5801 will maintain a relatively stable range. This is used to detect whether there is any leakage in the latex tubing covering the lower clamping block 5320, the middle clamping block 5420, and the upper clamping block 5520. If there is no leakage, the suction resistance detection module 5000 is in normal condition. Then the control solenoid valve MV14 opens, the needle cylinder 5700 starts, and the piston rod of the needle cylinder 5700 pops out.

[0336] (2) After the sample to be tested enters the suction resistance detection module 5000, it will remain at the upper end of the needle cylinder 5700 due to the limitation of the piston rod of the needle cylinder 5700. The latex tubes on the lower clamping block 5320, the middle clamping block 5420 and the upper clamping block 5520 cover the surface of the sample to be tested. The solenoid valves MV5 and MV6 are opened, and a stable airflow of 17.5 mL / s is formed in the pipeline under the combined action of CFO and vacuum generator 5801. The differential pressure sensor works and transmits the collected data to the sub-control system. The sub-control system transmits the data to the main control system. After the data is processed, the corresponding suction resistance value and ventilation rate value are displayed on the display. When the data acquisition is completed, the control solenoid valve MV14 is closed, the needle cylinder 5700 is closed, and the piston rod of the needle cylinder 5700 is retracted, so that the sample to be tested can fall to the hardness detection module 6000 below.

[0337] (3) After the sample to be tested falls, control solenoid valves MV5, MV6, MV7, MV8, MV9, and MV10 to close, and solenoid valve MV11 to open; the air source 5806 is connected to the detection chamber of the suction resistance detection module 5000, and the compressed air in the air source 5806 enters the detection chamber through the lower sliding block 5310 to blow away impurities such as tobacco. In this embodiment, after the sample to be tested has completed the detection and falls into the next detection module, the suction resistance detection module 5000 will open the solenoid valve switch to allow compressed air to enter the probe cavity through the lower sliding block 5310, thereby blowing away impurities such as tobacco inside the cavity and improving the accuracy and repeatability of the measurement results.

[0338] Step 6: The testing process of the sample under test in the hardness testing module 6000 is as follows:

[0339] (1) Before the sample to be tested enters the hardness testing module 6000, the pressure stepper motor 6431 is started, driving the pressure linear slide 6422 downward. When the pre-pressure plug 6445 contacts the pressure plate 6460 and supports the pressure weight 6447 to detach from the upper end of the air float block 6442, the pressure stepper motor 6431 is stopped, and the pressure linear slide 6422 stops moving. At this time, through the cooperation of the conical cylinder at the upper end of the pre-pressure column 6444 and the conical groove at the lower end of the pressure weight 6447, the pressure weight 6447 can automatically adjust to be concentric with the pre-pressure column 6444. Then, the pressure stepper motor 6431 is started again, controlling the pressure linear slide 6422 to move up a certain height and then stop. At this time, the pressure weight 6447 falls back onto the air float block 6442, and the square step of the pre-pressure column 6444 falls on the end face of the air float sleeve 6446. This is the initial measurement position.

[0340] (2) After the sample to be tested enters the hardness testing module 6000, the receiving cylinder 6230 is in a vertical position to receive the sample. Then, the rotating cylinder 6210 drives the receiving cylinder 6230 from a vertical position to a horizontal position. Under the action of the horizontal slide 6310, the pushing block 6330 pushes the sample to be tested onto the pressure plate 6460 and onto the horizontal surface directly below the air flotation pressure module. Then, the pressure stepper motor 6431 drives the pressure linear slide 6422 downward. When the pre-pressure plug 6445 contacts the sample to be tested, and the square step of the pre-pressure column 6444 disengages from the air flotation bushing 6446 and does not contact the pressure weight 6447, the pressure linear slide 6422 stops moving and remains in this position for a period of time. This is the pre-pressure measurement position.

[0341] (3) The pressure stepper motor 6431 drives the pressure linear slide 6422 to continue to descend. After the pre-pressure weight supports the pressure weight 6447 and separates from the air float 6442, the pressure linear slide 6422 stops moving and remains for a period of time. This is the full pressure measurement position.

[0342] (4) The linear slide 6422 is pressed up to the initial measurement position. The laser range sensor 6450 transmits the data to the sub-control system in real time. The sub-control system transmits the data to the main control system. After the data is processed, the corresponding hardness value is displayed on the screen.

[0343] (5) Under the action of the horizontal slide table 6310, the push block 6330 pushes the sample to be tested at a constant speed past the inkjet printer 6500. After the inkjet printer 6500 nozzle sprays powder onto the surface of the sample to be tested to form a barcode, the pressure push plate 6470 pushes the sample to be tested into the sorting and collection module 7000. At the same time, the hardness blowing block 6490 connects to the air source 5806 to blow away impurities such as tobacco on the pressure baffle 6480.

[0344] Step 7: Before the sample to be tested falls into the sorting and collection module 7000, the main control system determines whether the sample is qualified based on the detected data. When the sample is determined to be qualified, the micro rotary cylinder 7520 drives the steering plate 7540 to tilt towards the rear end, so that the sample is guided by the steering plate 7540 to the rear collection area of ​​the sorting and collection box 7300, i.e., the qualified product area, during the fall. When the sample is determined to be unqualified, the micro rotary cylinder 7520 drives the steering plate 7540 to tilt towards the front end, so that the sample is guided by the steering plate 7540 to the front collection area of ​​the sorting and collection box 7300, i.e., the unqualified product area, during the fall.

[0345] Perform steps 2 through 7 sequentially to complete the comprehensive testing of the subsequent samples.

[0346] If the sample to be tested does not require hardness testing, then after performing steps 1 to 7 in sequence, the sample will fall directly from the suction resistance detection module 5000 into the hardness untested collection box 7200 of the sorting and collection module 7000.
