Description

Technical Field

[0001] The present invention belongs to the technical field of measuring devices, and particularly relates to a hard cigarette case flip closing detection device and a detection method thereof. Background Art

[0002] In the traditional cigarette field, cigarette cases are used to hold cigarette sticks, and mostly use cardboard or soft paper as packaging materials. The main function is to store the cigarette sticks in a relatively stable space, prevent the cigarette sticks from being deformed by external forces, and at the same time play a certain airtight effect to avoid the cigarette sticks from getting damp, drying, oxidizing or having a smell, so as to ensure the relative stability of the smoking quality. Among them, the hard package flip-type cigarette case is a common type of cigarette case.

[0003] During the continuous use of the hard package flip-type cigarette case, as the number of cigarette sticks in the case gradually decreases, each time a cigarette is taken, the flip of the cigarette case needs to be opened, and after the cigarette is taken, the flip is closed again.

[0004] As the number of cigarette sticks in the case decreases, and along with the multiple opening and closing of the flip, when the flip is in the closed state and there is no external force, the flip will automatically rotate outward by a certain angle relative to the case under the action of its own elasticity. At this time, the flip and the case are in a state of not being tightly closed. If the angle of automatic outward rotation is too large, according to the feedback results of the social research conducted by our company, users will think that it is a quality problem of the cigarette case, which will seriously affect consumers' evaluation of the quality of this brand of cigarettes.

[0005] In our tobacco industry, this problem has not been taken seriously enough before, lacking attention to this problem and lacking equipment for standardized detection of it. Summary of the Invention

[0006] The purpose of the present invention is to provide a hard cigarette case flip closing detection device and a detection method thereof. The case of the cigarette case is fixed through a positioning groove, the flip of the cigarette case is clamped by a clamping mechanism with a clamping strip, then the flip is driven by a flipping mechanism to open and close reciprocally, and then the position of the flip is fixed by a fixing mechanism. Finally, the automatic flipping degree of the flip after multiple opening and closing operations is detected by a physical property test bench, improving the repeatability of the detection and supporting the detection results with specific data to improve the reliability of the detection.

[0007] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0008] A hard cigarette case flip - closing detection device, comprising a physical property test bench and a mounting frame. The physical property test bench includes a bench body, a lifting arm, a mounting arm and a pressure detection head. The physical property test bench is connected with a height measurement mechanism for monitoring the lifting height of the mounting arm. The mounting frame is installed on the bench body. A mounting plate is vertically installed on the mounting frame. A positioning groove for positioning and fixing the box body is installed on the mounting plate. A flipping mechanism is rotatably installed on the mounting plate. A clamping mechanism for clamping the flip is installed on the flipping mechanism. The clamping mechanism includes a front clamping plate and a rear clamping plate. A clamping strip is movably installed on the front clamping plate. A fixing mechanism for fixing the flip is also installed on the mounting plate.

[0009] Further defined, a hinge column is fixedly installed on the front end face of the front clamping plate. The clamping strip is rotatably installed on the hinge column. A pressing block is fixedly installed on the lower part of the clamping strip close to the flip side. With such a structural design, the clamping strip is rotatably installed on the front clamping plate through the hinge column. By rotating the clamping strip, the clamping and releasing of the flip by the clamping mechanism can be completed. The structure is simple and easy to use.

[0010] Further defined, the clamping mechanism further includes a support frame. The support frame is located between the front clamping plate and the rear clamping plate. L - shaped support legs are integrally formed on both the left and right sides of the support frame. Two guide rods are integrally formed at one end of the support frame close to the front clamping plate. Guide holes are opened on the front clamping plate. The guide rods are inserted into the guide holes. A stop block is fixedly installed at the free end of the guide rods. A compression spring is sleeved between the front clamping plate and the stop block on the guide rods. A first pull ring is installed on the front end face of the front clamping plate. With such a structural design, when using the clamping mechanism to clamp the flip, the front clamping plate can be pulled forward first through the first pull ring, then the clamping strip is rotated to a position where it can clamp the flip, and then the pulling is released. The compression spring drives the front clamping plate and the clamping block to move towards the flip direction, so that the clamping block contacts the flip. Similarly, when disassembling the cigarette case, the front clamping plate is also pulled through the first pull ring first, and then the clamping strip is rotated. This can avoid the problem that when directly rotating the clamping strip, the clamping block contacts the flip during the rotation of the clamping strip, resulting in damage to the flip and affecting the subsequent detection accuracy. The practicability is relatively strong.

[0011] Further defined, two guide rods are integrally formed at one end of the support frame close to the rear clamping plate, guide holes are also formed in the rear clamping plate, a compression spring is sleeved between the guide rods between the rear clamping plate and the stopper, the fixing mechanism includes two fixing rods slidably mounted on the mounting plate, the fixing rods are located on the left and right sides of the flip cover, fixing blocks are fixedly mounted on the inner walls of the fixing rods, a pushing block is also fixedly provided on the inner side of the upper part of the fixing rod, inclined notches are formed on both sides of the inner end of the pushing block, and an inclined block is integrally formed at each end of the inner walls of the front clamping plate and the rear clamping plate. With such a structural design, the rear clamping plate is also movably connected to the support frame. When it is necessary to fix and test the flip cover, the two fixing rods can be simultaneously pushed towards the cigarette case direction. By the mutual cooperation of the pushing block and the inclined block, the front clamping plate and the rear clamping plate are driven to move outwards simultaneously, disengaging from the contact with the flip cover, so that the flip cover can be flipped outwards relative to the box body by a certain distance under the action of its own elastic force, and then the flip cover is fixed by the fixing block, that is, the state of the flip cover being flipped outwards is maintained. Subsequently, the physical property test bench tests the automatic flipping position of the flip cover, which is more convenient to use.

[0012] Further defined, the support frame is in a square shape with an opening in the middle. With such a structural design, when testing the automatic flipping position of the flip cover by the physical property test bench, through the mutual cooperation of the pushing block and the inclined block, the front clamping plate and the rear clamping plate are respectively pushed open towards the front and rear ends, and the pressure detection head of the physical property test bench can extend into the middle of the square-shaped support frame and contact the flip cover fixed by the fixing block to complete the test of the flip cover position, without completely removing the clamping mechanism from the mounting plate, which is more convenient to use.

[0013] Further defined, an L-shaped connecting rod is fixedly mounted on the fixing rod, a strip-shaped chute is formed on the L-shaped connecting rod, a strip-shaped block is fixedly mounted in the strip-shaped chute on the mounting plate, and a limiting plate is fixedly mounted on the outer side of the L-shaped connecting rod at the free end of the strip-shaped block. With such a structural design, through the mutual matching of the strip-shaped block and the strip-shaped chute, and in cooperation with the limiting plate, the sliding installation between the fixing rod and the mounting plate is completed, with a simple structure and strong practicability.

[0014] Further defined, the two L-shaped connecting rods are arranged in a staggered manner, one above the other, on the back of the mounting plate, a synchronous gear is rotatably mounted on the back of the mounting plate, a first rack is mounted on the L-shaped connecting rod, and the two first racks are both meshed with the synchronous gear. With such a structural design, through the meshing of the first rack and the synchronous gear, a linkage relationship is formed between the two fixing rods. When moving one of the fixing rods, the other fixing rod is synchronously driven to move, which is more convenient to use.

[0015] It is further defined that a hinge seat is fixedly mounted on the mounting frame, a clamping rod is hinged on the hinge seat, the free end of the clamping rod is located below one of the L-shaped connecting rods, a U-shaped spring piece is installed between the free end of the clamping rod and the mounting frame, a clamping block is integrally formed on the upper end surface of the free end of the clamping rod, two clamping holes are provided on the lower end surface of the L-shaped connecting rod located above the free end of the clamping rod, and the clamping block is clamped in one of the clamping holes. With such a structural design, after the fixing block is pushed to clamp the flip cover, the clamping block is clamped in the clamping hole located on the inner side, thereby fixing the fixing block, and there is no need to continuously press the fixing block, which is more convenient to use.

[0016] It is further defined that the clamping block and the clamping opening are both inclined outward from top to bottom. With such a structural design, when the fixed block is used to clamp the flip cover, the fixed rod can be directly pushed inward by utilizing the inclined setting of the clamping block and the clamping opening, so that the clamping block can be separated from the clamping opening on the outside without pressing the clamping rod, which is more convenient to use.

[0017] It is further defined that two first ears are fixedly mounted on the mounting plate, a first guide rod is mounted between the two first ears, a first secondary ear is fixedly mounted on one of the L-shaped connecting rods, the first secondary ear is sleeved on the first guide rod, and a first return spring is sleeved between the first secondary ear and one of the first ears on the first guide rod. With such a structural design, after the fixed block completes the clamping of the flip cover, the clamping rod is pressed so that the clamping block is disengaged from the clamping port, and the fixed rod can move outward under the action of the first return spring to complete the reset of the fixed rod, and there is no need to manually pull the fixed rod, which is convenient to use.

[0018] The present invention also discloses a detection method of a hard cigarette box flip cover closure detection device, comprising the following steps:

[0019] 1) Flip the clip to make room for the cigarette box;

[0020] 2) Take the cigarette box to be tested, remove all the cigarettes in the cigarette box, then fix the box body of the cigarette box with the flip cover in the closed state in the positioning groove, and then rotate the clamping strip of the clamping mechanism to clamp the flip cover;

[0021] 3) The flip cover of the cigarette box is located directly below the pressure detection head, and the installation arm is driven to descend at a constant speed by the lifting arm of the physical property test bench, so that the pressure detection head is pressed on the flip cover of the cigarette box;

[0022] 4) The pressure detection head continues to descend, squeezing the flip cover of the cigarette box, and recording the downward pressure distance A of the mounting arm when the pressure detection head detects pressure;

[0023] 5) After the recording is completed, the pressure detection head is reset by the lifting arm;

[0024] 6) Start the flipping mechanism, use the flipping mechanism to flip the clamping mechanism, and then drive the flip cover to repeatedly open and close relative to the box body;

[0025] 7) After the flip cover opens and closes relative to the box body a certain number of times, cover the flip cover on the box body again, then release the clamping of the flip cover by the clamping mechanism, and then clamp the box body and the flip cover through the fixing mechanism;

[0026] 8) Drive the mounting arm to descend uniformly through the lifting arm of the physical property test bench, so that the pressure detection head presses on the flip cover of the cigarette case again;

[0027] 9) The pressure detection head continues to descend, squeezing the flip cover of the cigarette case, and record the downward pressing distance B of the mounting arm when the pressure detection head detects the pressure;

[0028] 10) Compare the downward pressing distance A and the downward pressing distance B. The height difference between the downward pressing distance A and the downward pressing distance B is the automatic springing amount of the flip cover of the cigarette case relative to the box body after being opened and closed a set number of times. Through this data, the automatic springing amount of the flip cover of the cigarette case relative to the box body after being opened and closed a set number of times can be judged. If the height difference is within the error range, it is judged as qualified, otherwise it is judged as unqualified.

[0029] The invention adopting the above technical solution has the following advantages:

[0030] 1. Fix the box body of the cigarette case through the positioning groove, clamp the flip cover of the cigarette case by the clamping mechanism with the clamping strip, then drive the flip cover to open and close reciprocally by the flipping mechanism, then fix the position of the flip cover by the fixing mechanism, and finally detect the automatic flipping degree of the flip cover after multiple openings and closings by the physical property test bench, improving the repeatability of the detection and supporting the detection structure with specific data, thus improving the reliability of the detection;

[0031] 2. The clamping strip is rotatably installed on the front clamping plate through the hinge column. By rotating the clamping strip, the clamping and relaxation of the flip cover by the clamping mechanism can be completed. The structure is simple and easy to use;

[0032] 3. Through the mutual cooperation of the front clamping plate and the compression spring, when using the clamping mechanism to clamp the flip cover, the front clamping plate can be pulled forward first through the first pull ring, then the clamping strip is rotated to a position where it can clamp the flip cover, and then the pulling is released. The compression spring drives the front clamping plate and the clamping block to move towards the flip cover, so that the clamping block contacts the flip cover; similarly, when disassembling the cigarette case, the front clamping plate is also pulled through the first pull ring first, and then the clamping strip is rotated. This can avoid the problem that when the clamping strip is directly rotated, the clamping block contacts the flip cover during the rotation process, resulting in damage to the flip cover and affecting the subsequent detection accuracy, and has strong practicability;

[0033] 4. The U-shaped elastic piece, the clamping rod with a clamping block integrally formed on the upper end surface of the free end, and the clamping opening formed on the lower end surface of the L-shaped connecting rod can cooperate with each other. After the fixing block is pushed to clamp the flip cover, the clamping block is clamped in the inner clamping opening to complete the fixation of the fixing block, eliminating the need for continuous pressing on the fixing block and making it more convenient to use.

[0052] The present invention will be described in detail below in conjunction with the drawings and specific embodiments. It should be noted that in the drawings or the description of the specification, similar or identical parts are all denoted by the same reference numerals. The implementation modes not shown or described in the drawings are in the forms known to those of ordinary skill in the art. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "rear", etc., are only references to the directions of the drawings and are not used to limit the protection scope of the present invention.

[0053] As Figures 1 to 8 shown, a hard cigarette case flip closing detection device of the present invention includes a physical property test bench 1 and a mounting rack 2. The physical property test bench 1 includes a bench body 11, a lifting arm 12, a mounting arm 13 and a pressure detection head 14. The physical property test bench 1 is connected with a height measurement mechanism for monitoring the lifting height of the mounting arm 13. The mounting rack 2 is mounted on the bench body 11. A mounting plate 21 is vertically mounted on the mounting rack 2. A positioning groove 22 for positioning and fixing the box body 101 is mounted on the mounting plate 21. A flipping mechanism is rotatably mounted on the mounting plate 21. A clamping mechanism for clamping the flip 102 is mounted on the flipping mechanism. The clamping mechanism includes a front splint 301 and a rear splint 302. A clamping strip 31 is movably mounted on the front splint 301. A fixing mechanism for fixing the flip 102 is also mounted on the mounting plate 21.

[0054] A hinge column 310 is fixedly mounted on the front end face of the front splint 301. The clamping strip 31 is rotatably mounted on the hinge column 310. A pressing block 311 is fixedly mounted on the lower part of the clamping strip 31 near the side of the flip 102. The clamping strip 31 is rotatably mounted on the front splint 301 through the hinge column 310. By rotating the clamping strip 31, the clamping mechanism can complete the fixing and relaxation of the flip 102. The structure is simple and easy to use.

[0055] The clamping mechanism further includes a support frame located between the front clamping plate 301 and the rear clamping plate 302. On both the left and right sides of the support frame, there are integrally formed L-shaped support legs 32. At one end of the support frame close to the front clamping plate 301, there are two integrally formed guide rods. The front clamping plate 301 is provided with guide holes, and the guide rods are inserted into the guide holes. A stop block 33 is fixedly installed at the free end of the guide rod. A compression spring 34 is sleeved between the front clamping plate 301 and the stop block 33 on the guide rod. A first pull ring 30 is installed on the front end face of the front clamping plate 301. When using the clamping mechanism to clamp the flip cover 102, the front clamping plate 301 can be first pulled forward through the first pull ring 30, then the clamping strip 31 is rotated to a position where it can clamp the flip cover 102, and then the pulling is released. The compression spring 34 is used to drive the front clamping plate 301 and the clamping block 311 to move towards the flip cover 301, so that the clamping block 311 contacts the flip cover 301. Similarly, when disassembling the cigarette case, the front clamping plate 301 is also pulled through the first pull ring 30 first, and then the clamping strip 31 is rotated. This can avoid directly rotating the clamping strip 31, which may cause the clamping block 311 to contact the flip cover 102 during the rotation process, resulting in damage to the flip cover 102 and affecting the subsequent detection accuracy. It has strong practicability.

[0056] At one end of the support frame close to the rear clamping plate 302, there are also two integrally formed guide rods. The rear clamping plate 302 is also provided with guide holes, and a compression spring 34 is also sleeved between the rear clamping plate 302 and the stop block 33 on the guide rod. The fixing mechanism includes two fixing rods 4 slidably installed on the mounting plate 21. The fixing rods 4 are located on the left and right sides of the flip cover 102. A fixing block 41 is fixedly installed on the inner wall of the fixing rod 4. A push block 42 is also fixedly provided on the inner side of the upper part of the fixing rod 4. Tilted notches 420 are formed on both sides of the inner end of the push block 42. At both ends of the inner walls of the front clamping plate 301 and the rear clamping plate 302, there is an integrally formed inclined block 43. The rear clamping plate 302 is also movably connected to the support frame. When it is necessary to fix and test the flip cover 102, the two fixing rods 4 can be simultaneously pushed towards the cigarette case. By the mutual cooperation of the push block 42 and the inclined block 43, the front clamping plate 301 and the rear clamping plate 302 are driven to move outward simultaneously, disengaging from the contact with the flip cover 102, so that the flip cover 102 can be flipped outward relative to the box body 101 by a certain distance under the action of its own elastic force, and then the flip cover 102 is fixed by the fixing block 41, that is, the state of the flip cover 102 being flipped outward is maintained. Subsequently, the physical property test bench 1 tests the automatic flipping position of the flip cover 102, which is more convenient to use.

[0057] The support frame is in a square shape. When testing the automatic flipping position of the flip cover 102 through the physical property test bench 1, the push block 42 and the inclined block 43 cooperate with each other to push the front clamping plate 301 and the rear clamping plate 302 towards the front and rear ends respectively. The pressure detection head 14 of the physical property test bench 1 can extend into the middle of the support frame in a square shape and contact the flip cover 102 fixed by the fixed block 41, completing the test of the position of the flip cover 102. There is no need to completely remove the clamping mechanism from the mounting plate 21, making it more convenient to use.

[0058] An L-shaped connecting rod 5 is also fixedly installed on the fixed rod 4. A strip-shaped chute 501 is provided on the L-shaped connecting rod 5. A strip-shaped block 502 is fixedly installed in the strip-shaped chute 501 on the mounting plate 21. A limiting plate 503 is fixedly installed at the free end of the strip-shaped block 502 outside the L-shaped connecting rod 5. Through the mutual matching of the strip-shaped block 502 and the strip-shaped chute 501, and in cooperation with the limiting plate 503, the sliding installation between the fixed rod 4 and the mounting plate 21 is completed. The structure is simple and the practicability is strong.

[0059] Two L-shaped connecting rods 5 are arranged in a staggered manner, one above the other, on the back of the mounting plate 21. A synchronous gear 510 is rotatably installed on the back of the mounting plate 21. A first rack 51 is installed on the L-shaped connecting rod 5. Both first racks 51 are engaged with the synchronous gear 510. Through the engagement of the first rack 51 and the synchronous gear 510, a linkage relationship is formed between the two fixed rods 4. When moving one of the fixed rods 4, the other fixed rod 4 is synchronously driven to move, making it more convenient to use.

[0060] A hinge seat 52 is fixedly installed on the mounting frame 2. A clamping rod 521 is hinged on the hinge seat 52. The free end of the clamping rod 521 is located below one of the L-shaped connecting rods 5. A U-shaped elastic piece 520 is installed between the free end of the clamping rod 521 and the mounting frame 2. A clamping block 522 is integrally formed on the upper end surface of the free end of the clamping rod 521. Two clamping openings 523 are provided on the lower end surface of the L-shaped connecting rod 5 above the free end of the clamping rod 521. The clamping block 522 is clamped in one of the clamping openings 523. After pushing the fixed block 41 to clamp the flip cover 102, the clamping block 522 is clamped in the inner clamping opening 523, completing the fixation of the fixed block 41. There is no need to continuously press the fixed block 41, making it more convenient to use.

[0061] Both the clamping block 522 and the clamping opening 523 are inclined outward from top to bottom. When using the fixed block 41 to clamp the flip cover 102, by utilizing the inclined settings of the clamping block 522 and the clamping opening 523, the fixed rod 4 can be directly pushed inward, and the clamping block 522 can be separated from the outer clamping opening 522 without pressing the clamping rod 521, making it more convenient to use.

[0062] Two first ear pieces 53 are fixedly installed on the mounting plate 21. A first guide rod is installed between the two first ear pieces 53. A first secondary ear piece 531 is fixedly installed on one of the L-shaped connecting rods 5. The first secondary ear piece 531 is sleeved on the first guide rod. A first return spring 532 is sleeved on the first guide rod between the first secondary ear piece 531 and one of the first ear pieces 53. After the fixing block 41 completes the clamping of the flip cover 102, press the clamping rod 521 to make the clamping block 522 disengage from the clamping notch 523. Then the fixing rod 4 can move outward under the action of the first return spring 532 to complete the reset of the fixing rod 4, without manually pulling the fixing rod 4, which is convenient to use.

[0063] A detection method for a hard cigarette case flip cover closing detection device includes the following steps:

[0064] 1) Flip the clamping strip 31 to make room for placing the cigarette case.

[0065] 2) Take the cigarette case to be detected. After removing all the cigarettes in the cigarette case, fix the box body 101 of the cigarette case with the flip cover 102 in the closed state in the positioning groove 22, and then rotate the clamping strip 31 of the clamping mechanism to clamp the flip cover 102.

[0066] 3) Make the flip cover 102 of the cigarette case be directly below the pressure detection head 14. Drive the mounting arm 13 to descend uniformly through the lifting arm 12 of the physical property test bench 1, so that the pressure detection head 14 presses on the flip cover 102 of the cigarette case.

[0067] 4) The pressure detection head 14 continues to descend to form extrusion on the flip cover 102 of the cigarette case, and record the downward pressing distance A of the mounting arm 13 when the pressure detection head 14 detects pressure.

[0068] 5) After the recording is completed, drive the pressure detection head 14 to reset through the lifting arm 12.

[0069] 6) Start the flipping mechanism, use the flipping mechanism to flip the clamping mechanism, and then drive the flip cover 102 to open and close repeatedly relative to the box body 101.

[0070] 7) After the flip cover 102 opens and closes relative to the box body 101 for a certain number of times, cover the flip cover 102 on the box body 101 again, then loosen the clamping of the flip cover 102 by the clamping mechanism, and then clamp the box body 101 and the flip cover 102 through the fixing mechanism.

[0071] 8) Drive the mounting arm 13 to descend uniformly through the lifting arm 12 of the physical property test bench 1, so that the pressure detection head 14 presses on the flip cover 102 of the cigarette case again.

[0072] 9) The pressure detection head 14 continues to descend to form extrusion on the flip cover 102 of the cigarette case, and record the downward pressing distance B of the mounting arm 13 when the pressure detection head 14 detects pressure.

[0073] 10) Compare the pressing-down distance A and the pressing-down distance B. The height difference between the pressing-down distance A and the pressing-down distance B is the automatic spring-up amount of the flip cover 102 of the cigarette case relative to the case body 101 after the flip cover 102 is opened and closed for a set number of times. Through this data, the automatic spring-up amount of the flip cover 102 of the cigarette case relative to the case body 101 after the flip cover 102 is opened and closed for a set number of times can be determined. If the height difference is within the error range, it is determined as qualified; otherwise, it is determined as unqualified.

[0074] The above has introduced in detail a hard cigarette case flip cover closing detection device and its detection method provided by the present invention. The description of the specific embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

After removing all the cigarettes in the cigarette case, fix the cigarette case body (101) with the flip cover (102) in the closed state in the positioning groove (22), and then rotate the clamping strip (31) of the clamping mechanism to clamp the flip cover (102). 3) Make the flip cover (102) of the cigarette case located directly below the pressure detection head (14). Drive the mounting arm (13) to descend uniformly through the lifting arm (12) of the physical property test bench (1) so that the pressure detection head (14) presses on the flip cover (102) of the cigarette case. 4) The pressure detection head (14) continues to descend to form extrusion on the flip cover (102) of the cigarette case, and record the downward pressing distance A of the mounting arm (13) when the pressure detection head (14) detects pressure. 5) After the recording is completed, drive the pressure detection head (14) to reset through the lifting arm (12). 6) Start the flipping mechanism, use the flipping mechanism to flip the clamping mechanism, and then drive the flip cover (102) to open and close repeatedly relative to the cigarette case body (101). 7) After the flip cover (102) opens and closes relative to the cigarette case body (101) a certain number of times, cover the flip cover (102) on the cigarette case body (101) again, then loosen the clamping of the flip cover (102) by the clamping mechanism, and then clamp the cigarette case body (101) and the flip cover (102) through the fixing mechanism. 8) Drive the mounting arm (13) to descend uniformly through the lifting arm (12) of the physical property test bench (1), so that the pressure detection head (14) presses on the flip cover (102) of the cigarette case again; 9) The pressure detection head (14) continues to descend, forming extrusion on the flip cover (102) of the cigarette case, and record the downward pressure distance B of the mounting arm (13) when the pressure detection head (14) detects pressure; 10) Compare the downward pressure distance A and the downward pressure distance B. The height difference between the downward pressure distance A and the downward pressure distance B is the automatic spring opening amount of the flip cover (102) of the cigarette case relative to the box body (101) after the flip cover (102) is opened and closed a set number of times. Through this data, the automatic spring opening amount of the flip cover (102) of the cigarette case relative to the box body (101) after the flip cover (102) is opened and closed a set number of times can be judged. If the height difference is within the error range, it is judged as qualified, otherwise it is judged as unqualified.
