Description

Technical Field

[0001] This invention belongs to the field of testing equipment technology, specifically relating to a stepped cigarette paper ink bursting test device. Background Technology

[0002] With the increasing use of base paper, composite paper, and transfer paper in packaging, the ability of paper to meet the printing requirements of specific packaging applications has become a crucial performance requirement. Generally, dyne pens and dyne solutions are used to test the surface strength of the paper's printing surface to characterize its suitability for printing, thereby controlling quality and reducing losses due to substandard materials. However, this method is not effective for quality inspection of cigarette packaging, such as cigarette boxes, and cannot meet the current demands for paper used in cigarette packaging. Summary of the Invention

[0003] The purpose of this invention is to provide a stepped ink bursting test device for cigarette paper, which solves the problem that existing ink bursting detection methods cannot accurately determine whether cigarette paper is qualified.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0005] A stepped cigarette paper ink-explosion testing device includes a conveying mechanism and a pressing mechanism. The conveying mechanism includes a bottom support, two sliding rods, a moving plate, a rack, a ninth gear, and a mounting shaft. The two sliding rods are horizontally fixedly mounted on the bottom support. The moving plate is slidably mounted between the two sliding rods. The rack is fixedly mounted on the lower end face of the moving plate and meshes with the ninth gear. The ninth gear is fixedly mounted on the mounting shaft, which is rotatably mounted on the bottom support. An eighth gear is also fixedly mounted on the mounting shaft. The pressing mechanism is located on one side of the conveying mechanism and includes a support frame, a lower fixed frame, an upper fixed frame, and a mounting frame. All components are fixedly mounted on the support frame. A lower roller and a rotating shaft are rotatably mounted between the lower fixed frame and the mounting frame. A first gear and a seventh gear are fixedly mounted on the rotating shaft. A synchronous belt is wound between the seventh gear and the eighth gear. A second gear, a third gear, a fourth gear, a fifth gear, and a sixth gear are rotatably mounted on the mounting frame, meshing sequentially. The first gear meshes with the second gear. The third gear is fixedly connected to the lower roller. An upper roller is rotatably mounted between the upper fixed frame and the mounting frame. The sixth gear is fixedly connected to the upper roller. The central axis of the upper roller is parallel to the central axis of the lower roller. The upper roller has a stepped shape that increases in size from the side closer to the conveying mechanism to the side farther away from the conveying mechanism.

[0006] Furthermore, the inner wall of the sliding rod is provided with a groove, and rolling wheels are rotatably mounted on both side walls of the moving plate, with the rolling wheels located within the groove. This structural design, through the cooperation of the rolling wheels and the groove, completes the sliding connection between the moving plate and the two sliding rods. The rolling friction between the rolling wheels and the groove replaces the sliding friction between the moving plate and the sliding rods, effectively reducing friction and making the movement of the moving plate smoother.

[0007] Furthermore, one end of each of the two sliding rods is fixedly mounted with a first fixing rod, and the other end is detachably mounted with a second fixing rod. This structural design limits the maximum sliding position of the moving plate through the first and second fixing rods, preventing the moving plate from sliding out of the range of the sliding rods and causing it to fall.

[0008] Furthermore, a fixed base is fixedly installed on the lower end face of the movable plate, a guide rod is fixedly installed on the fixed base, and a stop is fixedly installed on the bottom bracket. The stop has a guide hole, and the free end of the guide rod passes through the guide hole. A compression spring is sleeved between the guide rod and the fixed base and the stop. This structural design, through the interaction of the compression spring and the movable plate, allows the movable plate to automatically reset under the action of the compression spring after a test of the cigarette paper is completed, once the cigarette paper is removed and the movable plate is released, facilitating the next test.

[0009] Further, the movable plate is fixedly equipped with a baffle at its front end and a pusher plate at its rear end. This structural design uses the baffle to block the front end of the cigarette paper, limiting its position when placed on the movable plate and preventing it from being placed too far forward, which could prevent the cigarette paper from entering the space between the upper and lower rollers. The pusher plate provides support for the user's hand. During testing, the cigarette paper can be placed on the movable plate with the folded portion outside the plate, corresponding to the gap between the upper and lower rollers. The front end of the cigarette paper rests against the baffle plate, and the user's left hand, except for the thumb, presses down on the cigarette paper to secure it. The thumb presses down on the pusher plate, pushing the movable plate to allow the cigarette paper to enter the space between the upper and lower rollers, completing the ink burst test.

[0010] Further specifying, the support frame includes a mounting plate, and the adjusting component includes a connector and an adjusting sleeve. The connector is fixedly connected to the upper fixed frame, and the connector has a rectangular cross-section. A rectangular hole is provided on the mounting plate, and the connector is slidably installed in the rectangular hole. A threaded post is integrally formed on the connector, and the adjusting sleeve is screwed onto the threaded post. The adjusting sleeve is located above the mounting plate, and an annular boss is integrally formed on the outer wall of the adjusting sleeve. A fixing ring is fixedly installed on the mounting plate, and the fixing ring has an L-shaped cross-section. The fixing ring is sleeved on the annular boss, and a limit block is also fixedly installed above the threaded post and the adjusting sleeve. This structural design, by rotating the adjusting sleeve, drives the threaded post to move up and down, thereby driving the upper fixed frame and the upper roller to move up and down, thus achieving the purpose of adjusting the distance between the upper and lower rollers. The structure is simple and the adjustment is convenient.

[0011] Furthermore, a limiting plate is movably installed on the side wall of the support frame. With this structural design, during use, the folded cigarette paper is placed on the moving plate, and then pushed towards the limiting plate so that the folded end of the cigarette paper rests against the side of the limiting plate. The moving plate is then pushed forward to complete the ink burst test on the cigarette paper. The limiting plate is located on the side of the support frame, and the upper rollers are divided into different levels according to their diameter at various positions. During testing, the position of the limiting plate is adjusted according to the level of the upper roller used, so that the crease line of the initially folded cigarette paper is exactly located on the corresponding level of the upper roller, thus completing the ink burst test on the cigarette paper.

[0012] Further specifying, the support frame has a strip-shaped hole on its side wall, and multiple notches are evenly distributed within the strip-shaped hole. Two or more connecting columns are fixedly installed on the limiting plate near the support frame. These connecting columns are located within the notches, and each connecting column has a protruding post at its free end. The diameter of the protruding post is larger than the diameter of the connecting column. With this structural design, the limiting plate is movably installed within the notches of the support frame via the connecting columns. Adjusting the position of the limiting plate simply requires pulling it upwards to disengage the connecting column from the notch and into the strip-shaped hole, then pulling the limiting plate laterally to the desired position, and finally pushing it downwards to engage the connecting column in the new notch. This allows for convenient adjustment.

[0013] Furthermore, a retaining plate is fixedly installed on the side of the limiting plate near the conveying mechanism, and a retaining groove is horizontally formed on the retaining plate. This structural design allows the folded end of the initially folded cigarette paper to be inserted into the retaining groove during use. The retaining groove of the retaining plate secures the folded end of the cigarette paper, preventing the folded end from expanding and opening during testing, thus avoiding the problem of the cigarette paper not being able to be compressed around the crease line.

[0014] Furthermore, a horizontal plate is fixedly provided on the outer side of the limiting plate. This structural design allows for easier operation of the limiting plate by directly grasping the horizontal plate when changing its position.

[0015] The invention employing the above technical solution has the following advantages:

[0016] 1. By setting the upper rollers into a stepped structure with different diameters, during the test, the folded part of the cigarette paper comes into contact with the upper rollers of different levels, thereby performing a squeezing and ink bursting test on the initially folded cigarette paper. Based on the level of the upper rollers used when the cigarette paper bursts ink, the ink bursting limit of the cigarette paper can be obtained, resulting in high detection accuracy.

[0017] 2. The folded cigarette paper is restrained by the limiting plate. When using it, after fixing the position of the limiting plate, you only need to put the cigarette paper against the limiting plate, which makes it more convenient to use.

[0018] 3. By moving the movable plate, the upper and lower rollers can be rotated together to complete the ink bursting test on the cigarette paper. No additional power components are needed to drive the upper and lower rollers to rotate, thus reducing manufacturing costs.

[0019] 4. Through the cooperation of the compression spring and the moving plate, after completing a test of the cigarette paper, the cigarette paper is removed and the moving plate is released. At this time, the moving plate can automatically reset under the action of the compression spring, which is convenient for the next test. Attached Figure Description

[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0036] like Figures 1 to 8As shown, a stepped cigarette paper ink-explosion testing device of the present invention includes a conveying mechanism 1 and a pressing mechanism 3. The conveying mechanism 1 includes a bottom support 10, two sliding rods 11, a moving plate 12, a rack 13, a ninth gear 59, and a mounting shaft 14. The two sliding rods 11 are horizontally fixedly installed on the bottom support 10. The moving plate 12 is slidably installed between the two sliding rods 11. The rack 13 is fixedly installed on the lower end face of the moving plate 12 and meshes with the ninth gear 59. The ninth gear 59 is fixedly installed on the mounting shaft 14. The mounting shaft 14 is rotatably installed on the bottom support 10. An eighth gear 58 is also fixedly installed on the mounting shaft 14. The pressing mechanism 3 is located on one side of the conveying mechanism 1. The pressing mechanism 3 includes a support frame 30, a lower fixed frame 31, an upper fixed frame 32, and a mounting frame 33. The lower fixed frame 31, the upper fixed frame 32, and the mounting frame 33 are all fixed. Mounted on the support frame 30, a lower roller 310 and a rotating shaft 311 are rotatably mounted between the lower fixed frame 31 and the mounting frame 33. A first gear 51 and a seventh gear 57 are fixedly mounted on the rotating shaft 311. A synchronous belt 570 is wound between the seventh gear 57 and the eighth gear 58. A second gear 52, a third gear 53, a fourth gear 54, a fifth gear 55, and a sixth gear 56 are rotatably mounted on the mounting frame 33, meshing sequentially. The first gear 51 meshes with the second gear 52, and the third gear 53 is fixedly connected to the lower roller 310. An upper roller 320 is rotatably mounted between the upper fixed frame 32 and the mounting frame 33. The sixth gear 56 is fixedly connected to the upper roller 320. The central axis of the upper roller 320 is parallel to the central axis of the lower roller 310. The upper roller 320 is stepped from small to large from the side closer to the conveying mechanism 1 to the side farther away from the conveying mechanism 1.

[0037] The inner wall of the sliding rod 11 has a groove 110, and rolling wheels 120 are rotatably mounted on both side walls of the moving plate 12, with the rolling wheels 120 located within the groove 110. Through the cooperation of the rolling wheels 120 and the groove 110, a sliding connection is established between the moving plate 12 and the two sliding rods 11. The rolling friction between the rolling wheels 120 and the groove 110 replaces the sliding friction between the moving plate 12 and the sliding rods 11, effectively reducing friction and making the movement of the moving plate 12 smoother.

[0038] Two sliding rods 11 are fixedly mounted with a first fixing rod 111 at one end and a second fixing rod 112 detachably mounted at the other end. The first fixing rod 111 and the second fixing rod 112 limit the maximum sliding position of the moving plate 12, preventing the moving plate 12 from sliding out of the range of the sliding rods 11 and causing the moving plate 12 to fall.

[0039] A fixed base 2 is also fixedly installed on the lower end face of the movable plate 12. A guide rod 21 is fixedly installed on the fixed base 2. A stop 22 is also fixedly installed on the bottom bracket 10. A guide hole is opened on the stop 22, and the free end of the guide rod 21 passes through the guide hole. A compression spring 23 is sleeved between the guide rod 21 and the fixed base 2 and the stop 22. Through the cooperation between the compression spring 23 and the movable plate 12, after completing a test of the cigarette paper, the cigarette paper is removed and the movable plate 12 is released. At this time, the movable plate 12 can automatically reset under the action of the compression spring 23, which is convenient for the next test.

[0040] A baffle 121 is fixedly provided at the front end of the movable plate 12, and a push plate 122 is fixedly provided at the rear end. The baffle 121 blocks the front end of the cigarette paper, limiting the position of the front end of the cigarette paper when it is placed on the movable plate 12, thus preventing the cigarette paper from being placed too far forward and thus preventing it from entering the space between the upper roller 320 and the lower roller 310. The push plate 122 provides support for the user's hand. During testing, the cigarette paper can be placed on the movable plate 12 with the folded part outside the movable plate 12, corresponding to the gap between the upper roller 320 and the lower roller 310. The front end of the cigarette paper rests against the baffle 121, and the user's left hand, except for the thumb, presses on the cigarette paper to fix it. The thumb presses on the push plate 122 to push the movable plate 122, thereby allowing the cigarette paper to enter the space between the upper roller 320 and the lower roller 310, completing the ink burst test.

[0041] A limiting plate 4 is movably installed on the side wall of the support frame 30. In use, after placing the folded cigarette paper on the movable plate 12, the cigarette paper is pushed towards the limiting plate 4 so that the folded end of the cigarette paper rests against the side of the limiting plate 4. Then, the movable plate 12 is pushed forward to complete the ink burst test on the cigarette paper. The limiting plate 4 is located on the side of the support frame 30. The upper rollers 320 are divided into different levels according to their diameter at various positions. During testing, the position of the limiting plate 4 is adjusted according to the level of the upper roller 320 used, so that the crease line of the initially folded cigarette paper is exactly located on the corresponding level of the upper roller 320, thus completing the ink burst test on the cigarette paper.

[0042] The support frame 30 has a strip-shaped hole 301 on its side wall. Multiple notches 302 are evenly distributed within the strip-shaped hole 301. Two or more connecting posts 401 are fixedly installed on the side of the limiting plate 4 near the support frame 30. The connecting posts 401 are located within the notches 302, and a protruding post 402 is installed at the free end of each connecting post 401. The diameter of the protruding post 402 is larger than the diameter of the connecting post 401. The limiting plate 4 is movably installed within the notches 302 of the support frame 30 via the connecting posts 401. To adjust the position of the limiting plate 4, simply pull the limiting plate 4 upwards to disengage the connecting post 401 from the notch 302 and into the strip-shaped hole 301. Then, pull the limiting plate 4 laterally to the desired position. Finally, push the limiting plate 4 downwards to engage the connecting post 401 into the new notch 302. Adjustment is convenient.

[0043] A retaining plate 41 is fixedly installed on the side of the limiting plate 4 near the conveying mechanism 1. A retaining groove 410 is horizontally opened on the retaining plate 41. In use, the folded end of the cigarette paper after preliminary folding can be inserted into the retaining groove 410. The retaining groove 410 of the retaining plate 41 fixes the folded end of the cigarette paper, preventing the folded end of the cigarette paper from expanding and opening up during testing, thus preventing the cigarette paper from being squeezed around the fold line as the center.

[0044] A horizontal plate 42 is also fixedly provided on the outer side of the limiting plate 4. When changing the position of the limiting plate 4, the limiting plate 4 can be operated by directly grasping the horizontal plate 42, making it more convenient to use.

[0045] In this embodiment, before use, the connecting post 401 of the limiting plate 4 is placed in the corresponding notch 302, and then the cigarette paper is placed on the moving plate 12, so that the folded part of the cigarette paper abuts against the slot 410 of the card plate 41, corresponding to the gap between the upper roller 320 and the lower roller 310. The front end of the cigarette paper abuts against the baffle 121. The user's left hand, except for the thumb, presses the cigarette paper with the fingers to fix it. The thumb presses on the push plate 122 to push the moving plate 122, so that the cigarette paper enters between the upper roller 320 and the lower roller 310.

[0046] During the process of pushing the movable plate 12, the rack 13 meshes with the ninth gear 59, which drives the mounting shaft 14 to rotate. Then, through the synchronous belt 570 wound between the seventh gear 57 and the eighth gear 58, the seventh gear 57 is driven to rotate, which in turn drives the first gear 51 to rotate through the rotating shaft 311, and then drives the third gear 53 and the sixth gear 56 to rotate, thus causing the upper roller 320 and the lower roller 310 to rotate.

[0047] That is, when in use, when the moving plate 12 is pushed, the lower roller 310 and the lower roller 320 rotate simultaneously. As the moving plate 12 is pushed, the cigarette paper that has been initially folded (initial folding refers to folding the cigarette paper along the crease line so that one end of the cigarette paper is attached to the inside of the cigarette paper without causing excessive pressure on the crease line) moves forward until the folded part of the cigarette paper enters between the lower roller 310 and the upper roller 320. Through the pressure of the lower roller 310 and the upper roller 320, the ink bursting test of the cigarette paper is completed.

[0048] If no ink bursting occurs in one experiment, move the limiting plate 4 away from the conveying mechanism 1 by a gap 302 so that the position of the limiting plate 4 corresponds to the new level of the upper roller 320. Then, place the cigarette paper that has undergone one ink bursting test back on the moving plate 12. The folded part of the cigarette paper rests against the slot 410 of the card plate 41. Then push the moving plate 12 forward to complete the second ink bursting test of the cigarette paper.

[0049] Repeat the above steps until ink bursts at the creases of the cigarette paper.

[0050] The above provides a detailed description of the stepped ink-explosion testing device for cigarette paper provided by the present invention. The specific embodiments are described only to aid in understanding the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
