Description

Technical Field

[0001] This utility model relates to the field of tobacco detection technology, and in particular to a detection device for a flavor capsule filter rod. Background Technology

[0002] Filters are one of the important raw materials in cigarette production. With the development of tobacco product technology, filter sticks containing flavor capsules (i.e., flavor capsule cigarettes) have gained widespread attention from consumers due to their unique flavor. Flavor capsule cigarettes are made by inserting capsules containing liquid flavorings into the filter stick through a special process. When a consumer smokes a flavor capsule cigarette, they squeeze the capsule to break it, allowing the liquid flavorings to infuse into the filter stick fibers, resulting in a more unique and mellow flavor.

[0003] In menthol capsule cigarettes, the cigarette surface usually has a prominent marking indicating the axial position of the capsule in the filter, making it easy for consumers to identify. However, during the production process, the capsule's position often shifts, exceeding the standard range specified by the manufacturing process. This makes it difficult for consumers to accurately feel the capsule in the filter, and in severe cases, the capsule may even shift to the cut edge of the filter, causing damage or even the absence of the capsule, affecting the consumer's smoking experience. Therefore, to ensure the quality of menthol capsule cigarettes, strict quality monitoring of the menthol capsule filter is necessary.

[0004] Traditional testing methods typically involve visual inspection by personnel or the use of specialized instruments to check the position of the burst beads in the filter rod. Visual inspection involves placing the filter rod to be tested alongside a standard filter rod under light for comparison, roughly determining if the position of the burst beads meets the standard. This method is time-consuming and inefficient. Specialized testing equipment can accurately measure and automatically determine whether the position of the burst beads in the filter rod is up to standard; however, such equipment is usually large and expensive, and since multiple stages in the production process of the filter rod require inspection, specialized equipment is not portable and cannot be moved around easily. Utility Model Content

[0005] The purpose of this invention is to solve the problems of low detection efficiency, poor accuracy, and poor portability of existing methods for detecting the position of popping beads. This invention provides a popping bead filter rod detection device that can quickly and accurately check the position of popping beads in the filter rod to determine whether it meets the process standards. Moreover, this device is easy to carry and inexpensive.

[0006] To solve the above-mentioned technical problems, this utility model discloses a device for detecting popping bead filter rods, comprising:

[0007] The base has a detection light source on it;

[0008] A sample container is located above the base and extends along a first direction. The two ends of the sample container along the first direction are a hinged end and a free end, respectively. The hinged end is hinged to the base. A receiving cavity is provided on the end face of the free end of the sample container. The receiving cavity extends along the first direction and is used to hold filter rods.

[0009] The sample container is made of transparent material. The surface of the sample container facing away from the base is a marking surface. At least one first detection line group is provided on the marking surface. The first detection line group includes a first control line and a second control line that are spaced apart along a first direction. Both the first control line and the second control line extend along a second direction, which is perpendicular to the first direction.

[0010] The end face of the cavity near the hinge end is the reference surface; when the end face of the filter rod is in contact with the reference surface, and the popping beads inside the filter rod are completely located between the first reference line and the second reference line, the position of the popping beads is qualified.

[0011] When it is necessary to test the position of the burst beads in the filter rod, the operator first inserts the filter rod to be tested into the receiving cavity through the opening at the free end. Since the sample holder is hinged to the base, the sample holder can rotate relative to the base. The operator can rotate the sample holder to a vertical position before placing the filter rod into the receiving cavity. Under the action of its own weight, the filter rod slides downwards, ensuring that the end face of the filter rod is in contact with the reference surface. No manual pushing of the filter rod towards the reference surface is required, making it convenient and quick. With the end face of the filter rod in contact with the reference surface, the sample holder is rotated to a horizontal position. At this time, the sample holder is in contact with the base, and the detection light source shines through the transparent sample holder onto the filter rod and the marked surface. Then, the position of the burst beads is observed. When the burst beads are completely located between the first and second control lines, it indicates that the position of the burst beads is within the standard position range, and the position of the burst beads is qualified. When the burst beads are not completely located between the first and second control lines, it indicates that the position of the burst beads is outside the standard range, and the position of the burst beads is unqualified.

[0012] By employing the above technical solution, the position of the bursting bead filter rod in the filter rod can be detected using the device provided in this application. This allows for quick and accurate determination of whether the position of the bursting bead is qualified, and it is less susceptible to subjective factors. Furthermore, the device is inexpensive, portable, and convenient for operators to use in different areas. Additionally, the sample container is hinged to the base, making it easier for operators to place the filter rod into the receiving cavity. When the sample container is rotated to a vertical position, the filter rod can slide downwards under its own weight, ensuring that the end face of the filter rod abuts against the reference surface, thus improving the operator's detection efficiency and accuracy.

[0013] Optionally, the number of first detection line groups is 4, and each first detection line group is arranged at intervals along the first direction. The distance between the first control line and the second control line in the same first detection line group is 3mm.

[0014] Optionally, the inner surface of the receiving cavity away from the marking surface is the first inner surface. The first inner surface is provided with a plurality of grooves spaced apart along the second direction. The grooves extend along the first direction and the cross-sectional shape of the grooves is an arc-shaped indentation facing the first inner surface. The grooves are used to hold a single filter rod.

[0015] By employing the above technical solution, the grooves can be used to limit the position of the filter rods, ensuring that they are placed neatly and orderly within the receiving cavity without tilting, thus improving the accuracy of the test. Furthermore, the receiving cavity has multiple grooves, allowing operators to observe multiple filter rods simultaneously, improving work efficiency.

[0016] Optionally, the detection device further includes:

[0017] The slide is set on the marked surface and extends along the first direction. The slide is connected to the receiving cavity. The slide is set opposite to one of the grooves. The groove opposite to the slide is a positioning groove. The radius of the cross-section of the positioning groove is equal to the radius of the filter rod.

[0018] A cutting component is at least partially disposed within a slide and is capable of reciprocating along the slide. A cutting edge is provided on the side of the cutting component facing the positioning groove, and the projection of the cutting edge on the marking surface coincides with the projection of the axis of the positioning groove on the marking surface.

[0019] The filter rod placed in the positioning groove is the filter rod to be cut. The cutting component can move between a first position and a second position along a third direction, and the third direction is perpendicular to both the first and second directions. When the cutting component is in the first position, the blade can be at least partially inserted into the filter rod to be cut. When the cutting component is in the second position, the blade is located outside the filter rod to be cut.

[0020] Using the above technical solution, the filter rod can be quickly and accurately cut through the synergistic action of the slide, cutting component, and positioning groove, making operation convenient. Furthermore, the cut of the filter rod is relatively regular, minimizing damage to the original centerline adhesive and fiber bundle condition. Simultaneously, the blade inserts only a shallow depth into the filter rod to be cut, preventing damage to the burst beads inside, allowing operators to easily observe the state of the centerline adhesive and fiber bundle inside the filter rod, as well as the quality of the burst beads.

[0021] Optionally, the slitting component includes:

[0022] A sliding block is disposed within a slide rail. The dimension of the sliding block in a third direction is greater than the depth of the slide rail. The sliding block can slide within the slide rail in a first direction and can move within the slide rail in a third direction.

[0023] The movable button is connected to the end of the sliding block facing away from the receiving cavity. The movable button is located outside the sample container, and the dimension of the movable button along the second direction is greater than the width of the slide.

[0024] The limiting block is connected to the end of the sliding block facing the receiving cavity. The limiting block is located inside the receiving cavity, and the dimension of the limiting block along the second direction is greater than the width of the slide.

[0025] The blade is connected to the end of the limiting block facing the receiving cavity, and the cutting edge is located on the blade;

[0026] A spring, fitted onto a sliding block, is capable of producing elastic deformation along a third direction.

[0027] Using the above technical solution, as the blade moves away from the receiving cavity, the blade will not come out of the slide because a limit block is provided between the blade and the sliding block, and the width of the limit block along the second direction is greater than the size of the slide.

[0028] Optionally, the detection device further includes a second detection line group, which is disposed on the marking surface. The second detection line group includes a third control line and a fourth control line spaced apart along the first direction. Both the third control line and the fourth control line extend along the second direction. Each first detection line group is located between the hinge end of the second detection line group and the sample container. When the end face of one end of the filter rod is in contact with the reference surface and the end face of the other end of the filter rod is located between the third control line and the fourth control line, the length of the filter rod is qualified.

[0029] By employing the above technical solution, the length of the filter rod can be detected quickly and accurately by setting up detection line groups, making it less susceptible to subjective influences. Furthermore, each of the first detection line groups is located between the hinge end of the second detection line group and the sample container, ensuring that the detection of the filter rod length and the detection of the axial position of the internal bursting beads do not interfere with each other.

[0030] Optionally, the distance between the third control line and the fourth control line is 1 mm.

[0031] Optionally, the base includes a base plate and an upright plate, with the bottom of the upright plate connected to the upper surface of the base plate; the upright plate is provided with a set of detection holes, which includes a first detection hole and a second detection hole spaced apart along a second direction, the perimeter of the first detection hole being equal to the maximum limit perimeter of the filter rod, and the perimeter of the second detection hole being equal to the minimum limit perimeter of the filter rod.

[0032] By adopting the above technical solution and setting up a group of detection holes, it is possible to detect whether the circumference of the filter rod meets the standard. It has a wide range of applications and excellent functionality.

[0033] Optionally, the inner diameter of the first detection hole is 5.42 mm, and the inner diameter of the second detection hole is 5.28 mm.

[0034] Optionally, the base is made of polyetheretherketone (PEEK), and a control switch is installed on the base. A power supply is installed inside the base, and the detection light source is electrically connected to the power supply. The control switch is used to adjust the light intensity of the detection light source.

[0035] Using the above technical solution, the base made of polyetheretherketone (PEEK) is high in strength and wear-resistant, effectively preventing wear caused by repeated contact with the filter rod over a long period. Simultaneously, the light intensity of the detection light source is adjustable, adapting not only to different lighting environments but also to the detection needs of filter rods with different colors and light transmittance.

[0051] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0052] See Figure 1 The present invention discloses a device for detecting beaded filter rods, comprising:

[0053] Base 1, with a detection light source 11 mounted on it (see...) Figure 6 );

[0054] Sample container 2 is positioned above base 1, and the sample container 2 is positioned along the first direction (e.g., ...). Figure 1 Extending in the X direction (as shown), the sample container 2 has a hinged end 21 and a free end 22 at its two ends along the first direction, respectively. The hinged end 21 is hinged to the base 1. (See Figure 1) Figure 2 The sample container 2 has a receiving cavity 23 on the end face of the free end 22. The receiving cavity 23 extends along the first direction and is used to hold the filter rod.

[0055] The sample container 2 is made of transparent material. The surface of the sample container 2 facing away from the base 1 is a marking surface 24. The marking surface 24 is provided with at least one first detection line group 25. The first detection line group 25 includes a first control line 251 and a second control line 252 spaced apart along a first direction. The first control line 251 and the second control line 252 are both along a second direction (e.g., ...). Figure 1 As shown in the diagram, the Y direction extends, and the second direction is perpendicular to the first direction.

[0056] See Figure 3 The end face of the receiving cavity 23 near the hinge end 21 is the reference surface 231. When the end face of the filter rod is in contact with the reference surface 231, and the popping beads inside the filter rod are completely located between the first reference line 251 and the second reference line 252, the position of the popping beads is qualified.

[0057] When it is necessary to detect the position of the popping bead in the filter rod, the operator first inserts the filter rod to be tested into the receiving cavity 23 through the opening of the free end 22. Since the sample box 2 is hinged to the base 1, the sample box 2 can rotate relative to the base 1. The operator can rotate the sample box 2 to a vertical position before placing the filter rod into the receiving cavity 23. Under the action of the filter rod's own weight, the filter rod slides downward to ensure that the end face of the filter rod abuts against the reference surface 231. There is no need to manually push the filter rod towards the reference surface 231, which is convenient and quick. With the end face of the filter rod abutting against the reference surface 231, the sample box 2 is rotated to a horizontal position. At this time, the sample box 2 is in contact with the base 1, and the detection light source 11 shines through the transparent sample box 2 onto the filter rod and the marking surface 24, and then the position of the popping bead is observed. When the popping bead is completely located between the first reference line 251 and the second reference line 252, it indicates that the position of the popping bead is within the standard position range, and the position of the popping bead is qualified. When the burst bead is not completely located between the first control line 251 and the second control line 252, it indicates that the position of the burst bead is outside the standard range, and the position of the burst bead is unqualified.

[0058] By employing the above technical solution, the position of the bursting bead filter rod in the filter rod can be detected using the bursting bead filter rod detection device provided in this application. This allows for quick and accurate determination of whether the position of the bursting bead is qualified, and it is less susceptible to subjective factors. Furthermore, the device is inexpensive, portable, and convenient for operators to use in different areas. Additionally, the sample container 2 is hinged to the base 1, making it easier for operators to place the filter rod into the receiving cavity 23. When the sample container 2 is rotated to a vertical position, the filter rod can slide downwards under its own weight, ensuring that the end face of the filter rod abuts against the reference surface 231, thus improving the operator's detection efficiency and accuracy.

[0059] In one embodiment of this utility model, exemplarily, see [example]. Figure 4 The hinge end 21 of the sample container 2 is provided with a rotating shaft 17 on each side along the Y direction, see [reference]. Figure 6 The base 1 has two shaft holes 18, and two rotating shafts 17 are inserted into the two shaft holes 18 respectively to realize the rotational connection between the base 1 and the sample box 2.

[0060] In one embodiment of this utility model, for example, the detection light source 11 is an LED surface light source.

[0061] In one embodiment of this utility model, exemplarily, see [example]. Figure 6 The detection light source 11 is set in the base plate 12.

[0062] In one embodiment of this utility model, for example, the sample container 2 is made of highly transparent plexiglass material.

[0063] Specifically, see Figure 4The number of first detection line groups 25 is 4, and each first detection line group 25 is set at intervals along the first direction. The distance between the first control line 251 and the second control line 252 in the same first detection line group 25 is 3mm.

[0064] In actual production, to improve testing efficiency, the position of the four-times-long, uncut filter rod and the four embedded popping beads inside is usually tested. Therefore, the number of the first detection line group 25 is four. Relevant process standards specify that the upper limit of the standard popping bead position is when the center of the popping bead is located at the standard position of the popping bead +0.5mm, and the lower limit is when the center of the popping bead is located at the standard position of the popping bead -0.5mm. In this embodiment of the invention, the diameter of the popping beads in the filter rod to be tested is 2mm. When the center of the popping bead is offset by ±0.5mm along the filter rod axis, the calculated distance between the first reference line 251 and the second reference line 252 in the same first detection line group 25 should be 3mm.

[0065] Further, see Figure 2 The inner surface of the receiving cavity 23 away from the marking surface 24 is the first inner surface 232. The first inner surface 232 is provided with a plurality of grooves 233 spaced apart along the second direction. The grooves 233 extend along the first direction. The cross-sectional shape of the grooves 233 is an arc shape that is recessed towards the inside of the first inner surface 232. The grooves 233 are used to hold a single filter rod.

[0066] By employing the above technical solution, the grooves 233 can be used to limit the position of the filter rods, ensuring that the filter rods are placed neatly and orderly within the receiving cavity 23 without any tilting, thus improving the accuracy of the inspection. Furthermore, the receiving cavity 23 has multiple grooves 233, allowing operators to observe multiple filter rods simultaneously, improving work efficiency.

[0067] In one embodiment of this utility model, exemplarily, see [link to embodiment]. Figure 2 There are 11 grooves 233. The cross-section of groove 233 is arc-shaped, and the diameter of groove 233 is equal to the diameter of the filter rod, which is 5.35mm.

[0068] By adopting the above technical solution, by setting the cross-section of the groove 233 to be arc-shaped and the diameter of the groove 233 being comparable to the diameter of the filter rod, the outer circumferential surface of the filter rod can fit into the groove 233, preventing the filter rod from shaking in the receiving cavity 23 and enhancing the positioning effect of the filter rod.

[0069] Further, see Figure 1 , Figure 5 and Figure 8 The detection device also includes a slide 26 and a cutting assembly 4.

[0070] The slide 26 is disposed on the marking surface 24. The slide 26 extends along the first direction and is connected to the receiving cavity 23. The slide 26 is disposed opposite to one of the grooves. The groove disposed opposite to the slide 26 is the positioning groove 234. The radius of the cross-section of the positioning groove 234 is equal to the radius of the filter rod.

[0071] The cutting component 4 is at least partially disposed within the slide 26 and is capable of reciprocating along the slide 26. The side of the cutting component 4 facing the positioning groove 234 is provided with a cutting edge 441, and the projection of the cutting edge 441 on the marking surface 24 coincides with the projection of the axis of the positioning groove 234 on the marking surface 24.

[0072] The filter rod placed in the positioning groove 234 is the filter rod 3 to be cut, and the cutting component 4 can be cut along a third direction (such as...). Figure 5 The Z direction shown in the figure moves between the first position and the second position, and the third direction is perpendicular to both the first and second directions; when the cutting component 4 is in the first position, the blade 441 can be at least partially inserted into the filter rod 3 to be cut; when the cutting component 4 is in the second position, the blade 441 is above the filter rod 3 to be cut, and the blade 441 will not damage the filter rod 3 to be cut.

[0073] In one embodiment of the present invention, for example, when the cutting component 4 is in the first position, the blade 441 is inserted into the filter rod 3 to be cut to a depth of 1 mm.

[0074] When it is necessary to inspect the quality of the filter rod's centerline adhesive, filament bundle, and burst beads, the cutting component 4 can be used to cut open the forming paper wrapped around the filter rod. Specifically, the filter rod is inserted into the positioning groove 234 along its axial direction, and then the cutting component 4 is pressed down to move it to the first position. Once the blade 441 is inserted into the filter rod 3 to be cut, the operator pushes the cutting component 4 along the slide 26, cutting the forming paper on the filter rod with the blade 441, thus forming an opening along the filter rod's axial direction. This allows the operator to peel off the forming paper from the filter rod to further observe its internal structure and quality.

[0075] Using the above technical solution, the filter rod can be quickly and accurately cut through the synergistic action of the slide 26, the cutting component 4, and the positioning groove 234, making operation convenient. Furthermore, the cut of the filter rod is relatively regular, minimizing damage to the original centerline adhesive and fiber bundle condition. Simultaneously, the blade 441 inserts only a shallow depth into the filter rod 3 to be cut, preventing damage to the burst beads inside the filter rod, allowing operators to easily observe the state of the centerline adhesive and fiber bundle inside the filter rod, as well as the quality of the burst beads.

[0076] Specifically, see Figure 4 , Figure 5 , Figure 7 and Figure 8The cutting component 4 includes a sliding block 41, an active button 42, a limit block 43, a blade 44, and a spring 45.

[0077] The sliding block 41 is disposed in the slide rail 26. The dimension of the sliding block 41 in the third direction is greater than the depth of the slide rail 26. The sliding block 41 can slide in the slide rail 26 in the first direction and can move in the slide rail 26 in the third direction.

[0078] The active button 42 is connected to one end of the sliding block 41 that faces away from the receiving cavity 23. The active button 42 is located outside the sample container 2. The dimension of the active button 42 along the second direction is greater than the width of the slide 26.

[0079] The limiting block 43 is connected to the end of the sliding block 41 facing the receiving cavity 23. The limiting block 43 is located inside the receiving cavity 23. The dimension of the limiting block 43 along the second direction is greater than the width of the slide 26.

[0080] The blade 44 is connected to the end of the limiting block 43 facing the receiving cavity 23, and the cutting edge 441 is located on the blade 44.

[0081] Spring 45 is sleeved on sliding block 41, and spring 45 is capable of elastic deformation in a third direction.

[0082] When the active button 42 is pressed down, the blade 44 moves into the receiving cavity 23 along a third direction. When the pressing force is released, the spring 45 returns to its elastic deformation, and the blade 44 moves away from the receiving cavity 23, thereby automatically resetting the blade 44 to the second position. During the movement of the blade 44 away from the receiving cavity 23, because a limit block 43 is provided between the blade 44 and the sliding block 41, and the width of the limit block 43 along the second direction is greater than the size of the slide 26, the blade 44 will not dislodge from the slide 26.

[0083] Further, see Figure 3 and Figure 4 The detection device also includes a second detection line group 27, which is disposed on the marking surface 24. The second detection line group 27 includes a third control line 271 and a fourth control line 272 spaced apart along a first direction. Both the third control line 271 and the fourth control line 272 extend along a second direction. Each first detection line group 25 is located between the second detection line group 27 and the hinge end 21 of the sample container 2. When one end of the filter rod is in contact with the reference surface 231, and the other end of the filter rod is located between the third control line 271 and the fourth control line 272, the length of the filter rod is qualified. When one end of the filter rod is in contact with the reference surface 231, and the other end of the filter rod is not located between the third control line 271 and the fourth control line 272, the length of the filter rod is unqualified.

[0084] By adopting the above technical solution, the length of the filter rod can be detected by setting up detection line groups, which can quickly and accurately determine whether the length of the filter rod meets the standard and is not easily affected by subjective factors. Furthermore, each of the first detection line groups 25 is located between the second detection line group 27 and the hinge end 21 of the sample container 2, so that the detection of the filter rod length and the detection of the position of the bursting beads inside the filter rod will not interfere with each other.

[0085] Specifically, the distance between the third control line 271 and the fourth control line 272 is 1 mm.

[0086] Relevant process standards specify that the upper limit of the standard length of the filter rod is +0.5mm along the filter rod axis, and the lower limit is -0.5mm along the filter rod axis. In this embodiment of the invention, the standard length of the filter rod to be tested is 120mm, that is, the length range of the standard filter rod is 120±0.5mm. When the length of the filter rod is ±0.5mm along the filter rod axis, the calculated distance between the third reference line 271 and the fourth reference line 272 should be 1mm.

[0087] Further, see Figure 6 The base 1 includes a base plate 12 and a vertical plate 13, with the bottom of the vertical plate 13 connected to the upper surface of the base plate 12. The vertical plate 13 is provided with a detection hole group 14, which includes a first detection hole 141 and a second detection hole 142 spaced apart along a second direction. The perimeter of the first detection hole 141 is equal to the maximum limit perimeter of the filter rod, and the perimeter of the second detection hole 142 is equal to the minimum limit perimeter of the filter rod.

[0088] Using the above technical solution, by setting the detection hole group 14, the circumference of the filter rod can be tested to see if it meets the standard. It has a wide range of applications and superior functionality. Specifically, when the filter rod to be tested cannot pass through the detection hole corresponding to the minimum limit circumference, but can pass through the detection hole corresponding to the maximum limit circumference, the filter rod's circumference is considered qualified. When the filter rod to be tested can pass through both the detection holes corresponding to the minimum and maximum limit circumferences, the filter rod's circumference is too small and unqualified. When the filter rod to be tested cannot pass through either the detection hole corresponding to the minimum or maximum limit circumference, the filter rod's circumference is too large and unqualified.

[0089] Specifically, the inner diameter of the first detection hole 141 is 5.42 mm, and the inner diameter of the second detection hole 142 is 5.28 mm.

[0090] Relevant process standards indicate that the allowable processing error during actual processing should not exceed 0.2mm. In the embodiments of this utility model, the standard circumference of the filter rod is 16.8mm, that is, the standard circumference range of the filter rod is 16.8±0.2mm, the maximum limit circumference of the filter rod is 17mm, and the minimum limit circumference of the filter rod is 16.6mm. The circumference of the filter rod is considered qualified if it is between 16.6mm and 17mm. Calculations show that when the circumference of the filter rod is 17mm, its diameter is 5.42mm, and when the circumference of the filter rod is 16.6mm, its diameter is 5.28mm. When the filter rod to be tested can pass through the first detection hole 141 but cannot pass through the second detection hole 142, the circumference of the filter rod is considered to meet the standard. When the filter rod to be tested can pass through both the first detection hole 141 and the second detection hole 142, the circumference of the filter rod is too small, and the circumference of the filter rod is unqualified. When the filter rod to be tested cannot pass through either the first detection hole 141 or the second detection hole 142, the circumference of the filter rod is too large and the circumference of the filter rod is unqualified.

[0091] Further, see Figure 6 The base 1 is made of polyetheretherketone (PEEK). A control switch 15 is installed on the base 1. A power supply (not shown in the figure) is installed inside the base 1. The detection light source 11 is electrically connected to the power supply. The control switch 15 is used to adjust the light intensity of the detection light source 11.

[0092] Using the above technical solution, the base 1 made of polyetheretherketone (PEEK) is high in strength and wear-resistant, effectively preventing wear caused by repeated contact with the filter rod over a long period. Meanwhile, the light intensity of the detection light source 11 is adjustable, adapting not only to different lighting environments but also to the detection needs of filter rods with different colors and light transmittance.

[0093] In one embodiment of this utility model, exemplarily, see [example]. Figure 6 The base 1 is provided with a charging port 16, which is used to charge the power supply.

[0094] When quality monitoring of the burst bead filter rod is required, the circumference of the filter rod is first checked. Since the sample holder 2 has an open free end 22, the rear of the filter rod can extend into the receiving cavity 23 when inserted into the test hole. Therefore, the circumference can be checked even when the sample holder 2 is placed on the base 1, without rotating the sample holder 2. Specifically, first, insert a filter rod four times its length into the first test hole 141 of the test hole group 14. If the filter rod cannot be inserted smoothly, it indicates that the circumference of the filter rod is greater than the maximum limit circumference, and the circumference of the filter rod is unqualified. If the filter rod can be inserted smoothly, it indicates that the circumference of the filter rod is less than the maximum limit circumference, and subsequent testing can continue. Then, insert the filter rod into the second test hole 142. If the filter rod can still be inserted smoothly, it indicates that the circumference of the filter rod is less than the minimum limit circumference, and the circumference of the filter rod is unqualified. If the filter rod cannot be inserted smoothly into the second test hole 142, it indicates that the circumference of the filter rod is greater than the minimum limit circumference, and the circumference of the filter rod is qualified.

[0095] Then, rotate the sample container 2 to a vertical position, and insert the qualified filter rod selected in the previous step into the receiving cavity 23 through the opening of the free end 22 of the sample container 2. The filter rod slides in along the groove 233, and its end face abuts against the reference surface 231. Then rotate the sample container 2 to a horizontal position, at which point the sample container 2 is in contact with the base 1. Turn on the detection light source 11 by controlling the switch 15, and then detect the length of the filter rod. When the other end face of the filter rod is completely between the third reference line 271 and the fourth reference line 272, the length of the filter rod is qualified. When the other end face of the filter rod is not between the third reference line 271 and the fourth reference line 272, the length of the filter rod is unqualified.

[0096] Under the illumination of the detection light source 11, the positions of the popping beads in the filter rod are clearly visible. Next, the positions of the popping beads are detected. When all four popping beads are completely positioned between the first control line 251 and the second control line 252 corresponding to their respective positions, the position of the popping beads is acceptable. When the four popping beads are not completely positioned between the first control line 251 and the second control line 252 corresponding to their respective positions, the position of the popping beads is unacceptable.

[0097] After completing the appearance and dimensional inspections of the filter rods, the internal structure of the filter rods needs to be inspected. First, adjust the light source intensity according to the light transmittance of the filter rod and the type of embedded popping beads. Utilize the transmission of light to observe whether there are missing popping beads or abnormal coloring of the popping beads inside the filter rod. If any are found, the filter rod is unqualified.

[0098] When it is necessary to test the quality of the centerline adhesive, filament bundle, and burst beads of the filter rod, first rotate the sample box 2 to a vertical position, then place the filter rod to be tested into the positioning groove 234. After the end face of the filter rod abuts against the reference surface 231, rotate the sample box 2 to a horizontal position, at which point the sample box 2 is in contact with the base 1. Press the movable button 42 to extend the blade 441 of the blade 44 into the filter rod to be tested, and then slide the movable button 42 in the first direction. The forming paper on the filter rod is cut by the blade 441, forming an opening along the axis of the filter rod. Then, the filter rod is pulled out from the sample box 2, and the operator peels open the filter rod and tests the quality of the centerline adhesive, filament bundle, and burst beads by a combination of hand and eye. The testing device disclosed in this utility model has a simple structure, is easy to use, and has high functionality. It can judge whether the multi-dimensional parameters of the filter rod and its embedded burst beads are qualified through a single device, improving the testing efficiency of the operator. The cutting component on it is easy to operate, and its cutting openings are regular, making it less likely to damage the original internal structure of the filter rod. At the same time, this device is small in size, easy to carry, and can be used for testing in different production stages.
