Description

Technical Field

[0001] The invention belongs to the technical field of cigarette production and detection, and particularly relates to a rolling softness testing device suitable for cigarette boxes. Background Art

[0002] As the content of cigarette rods and box wrapping paper becomes richer, the substrates, printing processes, and inks used are becoming more diverse and complex. Therefore, their physical and chemical properties need to be tested before use. The physical property testing of wrapping paper includes testing its bending resistance to understand the softness of the cigarette box. First, the uncreased area of ​​the wrapping paper is cut to obtain a sample, and then the corresponding sample is subjected to a pressure test. Currently, when conducting a pressure test, the wrapping paper is often cut and sampled first, and then the sample is tested. During the test, the cigarette paper sample is placed on a support table, and then a fixed force is applied to the sample surface through a probe. The displacement change of the probe is detected to determine the deformation of the cigarette paper. Since the structure of the wrapping paper after being made into a cigarette box has a certain influence on the compressive strength of the cigarette paper, the test results of the cigarette paper are likely to differ from the softness of the cigarette box reagent. At the same time, since the structure of the packaging paper has a certain impact on the compressive strength of the cigarette paper after it is made into a cigarette box, and since creases are easily left around the cigarette paper when the cigarette paper sample is cut, the cigarette paper needs to be flattened before testing, and then the softness of the cigarette paper needs to be tested, which is a cumbersome operation. Summary of the Invention

[0003] Based on the problems mentioned in the above background technology, the present invention provides a rolling softness testing device suitable for cigarette boxes, which is used to test the softness of cigarette boxes and cigarette papers. At the same time, the cigarette paper can be rolled flat during the cigarette paper testing, which is more convenient to use.

[0004] The technical solution adopted in the present invention is as follows:

[0005] A rolling softness testing device suitable for cigarette boxes comprises an operating table, a texture analyzer is installed on the operating table, a probe is installed on the texture analyzer, two relatively arranged placement racks are installed on the operating table, the placement rack comprises a fixedly connected base and a mounting plate, a first slide groove is provided on the mounting plate, a first slider is installed in the first slide groove, one end of the first slider is fixedly mounted with a placement table, and the other end is hinged with an adjustment mechanism, the adjustment mechanism comprises a first U-shaped rack, a slide rail is installed on the first U-shaped rack, a second U-shaped rack is slidably mounted on the slide rail, an L-shaped hanging rod is fixedly mounted on the second U-shaped rack, a fastening screw is installed on the second U-shaped rack, two hinged seats are provided on the operating table, and the hinged seat A feed smoothing mechanism is hinged on the top, and the feed smoothing mechanism includes two mounting frames, the two mounting frames are respectively hinged on the hinged seat, a first rotating shaft is passed through the mounting frames, a first roller is fixedly mounted on the first rotating shaft, a support column is installed on the top of the mounting frame, a second rotating shaft is installed on the support column, a second roller is installed on the second rotating shaft, a driven wheel is installed at one end of the first rotating shaft, a stepper motor is installed on the operating table, a driving wheel is installed on the motor shaft of the stepper motor, the axis of the driving wheel is collinear with the rotation axis of the mounting frame, a transmission belt is installed between the driving wheel and the driven wheel, a fixing frame is installed on the operating table, a socket and a slot are provided on the fixing frame, a fixing column is passed through the socket.

[0006] On the basis of the above scheme, the present invention has also made the following improvements:

[0007] Furthermore, the mounting plate is provided with two first chutes, each of which is provided with a first slider, and the two first sliders mounted on the same mounting plate are fixedly connected to the same placement platform. The first sliders cooperate with the first chutes to limit the placement platform, thereby preventing the placement platform from tilting and affecting the placement of the cigarette box.

[0008] Furthermore, the mounting plate has second slots at both ends, each of which is fitted with a limit plate. The limit plates are perpendicular to and fixedly connected to the first slider. The limit plates cooperate with the second slots to limit the first slider, preventing the first slider from tilting, which would cause the placement platform to tilt and affect the placement of the cigarette box.

[0009] Furthermore, a limiting slot is provided on the slide rail, and a limiting block corresponding to the limiting slot is installed on the second U-shaped frame, and the limiting block is located in the limiting slot. The limiting slot and the limiting block cooperate to restrain the second U-shaped frame, thereby preventing the second U-shaped frame from falling and affecting its use after the fastening screws are loosened.

[0010] Furthermore, the surfaces of the first roller and the second roller are covered with a rubber layer, and the rubber layer improves the flexibility of the surfaces of the first roller and the second roller, so as to facilitate better rolling of cigarette paper.

[0011] Furthermore, a bracket is installed on the mounting frame, and a placement plate is installed on the bracket. The placement plate can serve as a supporting component to support the feed smoothing mechanism after the feed smoothing mechanism rotates, thereby preventing the first roller or the second roller from contacting the operating table and affecting its use.

[0012] Furthermore, a placement column is fixedly mounted on the top of each mounting plate. When testing a cigarette paper sample, the placement column contacts the cigarette paper, so that the cigarette paper sample is in line contact when it is flat or deformed, thereby reducing the impact on the test results.

[0013] Furthermore, the probe is spherical. By setting the probe to be spherical, the probe is in point contact with the surface of the cigarette paper sample or cigarette box, which reduces the influence of the probe on the deformation of the cigarette paper sample or cigarette box, and is conducive to improving the test accuracy.

[0014] Beneficial effects of the present invention:

[0015] 1. The softness of cigarette paper can be tested by placing a cigarette paper sample on a mounting plate and using the texture analyzer to drive the probe to squeeze the surface of the cigarette paper sample. The test results can be obtained by analyzing the relationship between the applied pressure and the deformation of the cigarette paper sample. At the same time, when testing the cigarette paper, the relative rolling of the first and second rollers can roll the cigarette paper to flatten the edges of the cigarette paper, preventing the edges from curling up and affecting the test results. At the same time, the relative rolling of the first and second rollers can bring the cigarette paper in, making loading more convenient;

[0016] 2. Place the cigarette box on the placement table, rotate the adjustment mechanism to make the first U-shaped frame contact the side wall of the mounting plate and the L-shaped hanging rod contact the top of the mounting plate, loosen the fastening screws to adjust the height of the placement table so that the upper surface of the cigarette box contacts the L-shaped hanging rod, ensuring that the upper surface of the cigarette box and the top of the mounting plate remain level. Different types of cigarette boxes can be fixed, and the softness of the cigarette box surface can be tested using the cigarette paper test method, which is relatively convenient to use.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

The two mounting frames 51 are respectively hinged on the hinge seat 11. A first rotating shaft 52 is passed through the mounting frames 51. A first roller 53 is fixedly mounted on the first rotating shaft 52. A supporting column 541 is installed at the top of the mounting frame 51. A second rotating shaft 54 ​​is installed on the supporting column 541. A second roller 55 is installed on the second rotating shaft 54. A driven wheel 56 is installed at one end of the first rotating shaft 52. A stepping motor 7 is installed on the operating table 1. A driving wheel 71 is installed on the motor shaft of the stepping motor 7. The axis of the driving wheel 71 is collinear with the rotation axis of the mounting frame 51. A transmission belt 72 is installed between the driving wheel 71 and the driven wheel 56. To prevent the transmission belt 72 from slipping, a transmission groove 561 is provided on the driven wheel 56 and the driving wheel 71. The transmission belt 72 is located in the transmission groove 561. A fixing frame 6 is installed on the operating table 1. The fixing frame 6 is provided with a socket 61 and a slot 62. A fixing column 64 is passed through the socket 61.

[0030] Specifically, two first chutes 43 are formed on the mounting plate 42, each of which is fitted with a first slider 461. The two first sliders 461 mounted on the same mounting plate 42 are fixedly connected to the same placement platform 46. The first sliders 461 cooperate with the first chutes 43 to limit the placement platform 46, preventing the placement platform 46 from tilting and affecting the placement of the cigarette box 8.

[0031] Specifically, a second slide groove 44 is provided at both ends of the mounting plate 42, and a limiting plate 462 is installed in each of the second slide grooves 44. The limiting plate 462 is perpendicular to the first slider 461 and is fixedly connected to the first slider 461. The limiting plate 462 cooperates with the second slide groove 44 to limit the first slider 461 to prevent the first slider 461 from tilting and causing the placement platform 46 to tilt, affecting the placement of the cigarette box 8.

[0032] Specifically, a limiting slot 321 is provided on the slide rail 32, and a limiting block corresponding to the limiting slot 321 is installed on the second U-shaped frame 33. The limiting block is located in the limiting slot 321. The second U-shaped frame 33 is restricted by the cooperation between the limiting slot 321 and the limiting block to prevent the second U-shaped frame 33 from falling and affecting its use after the fastening screw 331 is loosened.

[0033] Specifically, the surfaces of the first roller 53 and the second roller 55 are covered with a rubber layer, and the rubber layer improves the flexibility of the surfaces of the first roller and the second roller, so as to facilitate better rolling of the cigarette paper.

[0034] Specifically, a bracket 57 is installed on the mounting frame 51, and a placement plate 58 is installed on the bracket 57. The placement plate 58 can serve as a supporting component to support the feed smoothing mechanism 5 after the feed smoothing mechanism 5 rotates, thereby preventing the first roller 53 or the second roller 55 from contacting the operating table 1 and affecting its use.

[0035] Specifically, a placement column 45 is fixedly installed on the top of the mounting plate 42. When testing the cigarette paper sample, the placement column 45 contacts the cigarette paper, so that the cigarette paper sample is in line contact when it is laid flat or deformed, thereby reducing the impact on the test results.

[0036] Specifically, the probe 21 is spherical. By setting the probe 21 to be spherical, the probe 21 makes point contact with the surface of the cigarette paper sample or cigarette box, reducing the influence of the probe 21 on the deformation of the cigarette paper sample or cigarette box, which is conducive to improving the test accuracy.

[0037] When testing cigarette paper, the adjusting mechanism 3 is rotated to separate the L-shaped hanging rod 34 from the placement column 45, and then the cigarette paper sample is placed on the placement column 45. The mounting frame 51 is rotated to lock the mounting frame 51 into the card slot 62, and then the fixing column 64 is pushed to confine the mounting frame 51 in the card slot 62 so that the smoothing mechanism 5 is erected (as shown in FIG. Figure 3 As shown in FIG5 ), the stepper motor 7 is then started, and the stepper motor 7 drives the first roller 53 to rotate via the transmission belt 72. The first roller 53 then drives the second roller 55 to rotate. The cigarette paper to be tested is placed on the placement table 58 and pushed, so that the cigarette paper is stuck between the first roller 53 and the second roller 55. The first roller 53 and the second roller 55 roll the cigarette paper. At the same time, the relative rolling of the first roller 53 and the second roller 55 can bring the cigarette paper in, causing the cigarette paper to fall onto the placement column 45 by itself. Finally, the texture analyzer 2 drives the probe 21 to squeeze the surface of the cigarette paper sample to test the softness of the cigarette paper.

[0038] When the cigarette box needs to be tested, the cigarette box 8 is placed on the placement table 46, and then the fastening screw 331 is loosened and the adjustment mechanism 3 is rotated so that the first U-shaped frame 31 contacts the side wall of the mounting plate 42 and the L-shaped hanging rod 34 contacts the top of the placement column 45. Then, the height of the placement table 46 is adjusted so that the upper surface of the cigarette box contacts the L-shaped hanging rod 34, and then the fastening screw 331 is tightened to fix the placement table 46 to ensure that the upper surface of the cigarette box 8 is level with the top of the placement column 45. Then, the texture analyzer 2 drives the probe 21 to squeeze the upper surface of the cigarette box 8 to test the softness of the cigarette paper.

[0039] The above describes in detail the roller-type softness testing device for cigarette packages provided by the present invention. The description of the specific embodiments is intended only to facilitate understanding of the present invention's method and core concepts.
