Description

Technical Field

[0001] The invention belongs to the technical field of detection equipment, and in particular relates to a gradient-pushing type cigarette paper ink burst testing device. Background Art

[0002] As base paper, composite paper, transfer paper and other papers are increasingly used in packaging, whether the paper can meet the printing requirements of the specific packaging use is also a very important performance requirement.

[0003] Usually, the hand-folding method is used to check whether the cigarette paper has burst ink. Because everyone's technique and strength are different, it will affect the judgment of the quality of the cigarette paper. If a misjudgment occurs, it will directly affect the quality of the cigarette packaging and may even cause the entire batch of packaging to be scrapped. Summary of the Invention

[0004] The present invention aims to provide a gradient push-type cigarette paper ink burst testing device. By means of the interaction between a movable plate provided with stepped strip grooves, a support plate provided with stepped protrusions on its lower end surface, and a squeezing wheel, the height difference between the support plate and the squeezing wheel can be adjusted, thereby performing an ink burst test on preliminarily folded cigarette paper. The ink burst limit of the cigarette paper can be determined based on the position of the support plate when the cigarette paper bursts, thereby achieving high detection accuracy. By applying oblique downward pressure to the pushing frame, and then by the mutual engagement of the gear and rack, the squeezing wheel rolls and moves forward, thereby squeezing the cigarette paper placed on the support plate. The device has a simple structure and is easy to operate.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0006] The top end face of the supporting plate is fixedly provided with a toothed plate, and the bottom end face of the supporting plate is fixedly provided with a toothed plate.

[0007] Further specified, a support shaft is integrally formed at the left end of the extrusion wheel. The support shaft is coaxial with the extrusion wheel and has a smaller diameter than the extrusion wheel. Two gears and two racks are provided, with the two racks located on either side of the support plate. This structural design supports the right side of the extrusion wheel via the support shaft, which has a smaller diameter than the extrusion wheel, while also avoiding the fixing mechanism located on the right side of the support plate, thereby preventing the extrusion wheel from being obstructed by the fixing mechanism during movement.

[0008] Further defined, the sliding frame has an inner wall formed with a mounting groove, wherein a plurality of rolling wheels are rotatably mounted within the mounting groove, and the rolling wheels are located above the sliding rods. This structural design, through the interaction between the rolling wheels and the sliding rods, completes the sliding connection between the sliding frame and the two sliding rods. The rolling friction between the rolling wheels and the sliding rods replaces the sliding friction between the sliding frame and the sliding rods, effectively reducing friction and making the movement of the push frame smoother.

[0009] It is further defined that the connecting plate gradually tilts upward from front to back. With this structural design, when the pushing frame is pushed, the connecting plate gradually tilts upward from front to back, which can apply an oblique downward force to the squeezing wheel, causing the squeezing wheel to move backward. When performing the ink burst test on the cigarette paper, the squeezing wheel is subjected to downward pressure, thereby causing the squeezing wheel to closely contact the cigarette paper and causing the rolling wheel to closely contact the sliding rod.

[0010] Furthermore, the support plate has two detachable stoppers mounted on both ends of the sliding rod. This structural design limits the maximum sliding position of the sliding frame through the stoppers, thereby preventing the sliding frame from sliding out of the range of the sliding rod and causing the sliding frame to fall.

[0011] Further defined, a retaining bar is fixedly mounted on the right side of the upper end surface of the support plate, and a fixing mechanism for securing the cigarette paper is fixedly mounted on the retaining bar. This structural design allows the retaining mechanism to secure the cigarette paper to the support plate, preventing the cigarette paper from sliding during testing. The retaining bar can also define the position of the cigarette paper. During use, the edge of the cigarette paper cut to a specific size is placed against the retaining bar and then secured with the fixing mechanism.

[0012] The fixing mechanism further defines a structure comprising two inverted L-shaped fixing blocks, each having a through-hole formed therein. A lifting rod extends through the through-hole. A fixing head is fixedly mounted at the lower end of the lifting rod. The diameter of the fixing head is larger than that of the lifting rod. A compression spring is sleeved between the fixing block and the fixing head of the lifting rod. A pull ring is detachably mounted at the upper end of the lifting rod. This structural design secures the cigarette paper to the support plate by the compression spring pressing against the fixing head, resulting in a simple structure and ease of use.

[0013] Further defined, the lower end surface of the projection is provided with a transverse convex strip, and the support plate is provided with a plurality of transverse positioning grooves within the strip-shaped groove. This structural design, because the depth of the strip-shaped groove increases uniformly from left to right and forms a stepped shape, prevents the support plate from moving laterally to the left when the projection is snapped into the corresponding positioning groove without being lifted.

[0014] The invention further defines an L-shaped clamping block fixedly mounted on the front end of the base plate, wherein the L-shaped clamping block has a threaded hole, into which a fixing head is screwed. This structural design allows the fixing head and the L-shaped clamping block to be used to secure the test device to the edge of a laboratory table during actual use, thereby preventing the test device from moving during use.

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

[0016] 1. The interaction between the movable plate with stepped grooves, the support plate with stepped protrusions on the lower end, and the extrusion wheel allows the height difference between the support plate and the extrusion wheel to be adjusted, thereby performing an extrusion ink burst test on preliminarily folded cigarette paper. The ink burst limit of the cigarette paper can be determined based on the position of the support plate when the cigarette paper bursts, achieving high detection accuracy.

[0017] 2. By applying downward pressure to the pushing frame, the gear and rack mesh with each other, causing the squeezing wheel to roll and move forward, thereby squeezing the cigarette paper placed on the support plate. The structure is simple and the operation is convenient.

[0018] 3. By matching the convex strips with the multiple positioning grooves, after the boss is inserted into the corresponding positioning groove, the support plate can be prevented from moving horizontally to the right without being lifted;

[0019] 4. Fix the test device to the edge of the laboratory table using the fixed head and L-shaped block to prevent the test device from moving during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions, similar or identical parts are numbered the same. Implementations not shown or described in the drawings are forms known to those of ordinary skill in the art. In addition, directional terms mentioned in the embodiments, such as "upper," "lower," "top," "bottom," "left," "right," "front," and "back," are merely references to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0033] like Figures 1 to 5As shown, a gradient push-type cigarette paper ink explosion testing device of the present invention includes a support mechanism 1, an extrusion wheel 2 and a pushing frame 4. The support mechanism 1 includes a bottom plate 10, on which a support plate 11 is fixedly mounted. A sliding rod 12 is fixedly mounted on each side of the support plate 11. A rack 13 is also fixedly mounted laterally on the upper end surface of the support plate 11. A mounting shaft 14 is fixedly mounted on the extrusion wheel 2. A strip groove 30 is opened laterally on the upper end surface of the support plate 11. The depth of the strip groove 30 is evenly deepened from left to right and is stepped. The support plate 11 is detachable. A support plate 3 is installed, and a protrusion 31 is laterally provided on the lower end surface of the support plate 3. The cross-section of the protrusion 31 is in a stepped shape with the thickness evenly deepening from left to right. The pushing frame 4 includes a connecting plate 41, and sliding frames 42 are fixedly installed at both ends of the connecting plate 41. The extrusion wheel 2 is rotatably mounted on the sliding frame 42 through the mounting shaft 14 and is located on the left part above the support plate 11. The sliding frame 42 is slidably mounted on the sliding rod 12. A gear 21 is fixedly mounted on the side of the extrusion wheel 2, and the gear 21 is meshed with the rack 13. The diameter of the involute of the gear 21 is equal to the diameter of the outer contour of the extrusion wheel 2.

[0034] A support shaft 22 is integrally formed at the left end of the extrusion wheel 2. The support shaft 22 is coaxial with the extrusion wheel 2 and has a smaller diameter than the extrusion wheel 2. There are two gears 21 and two racks 13, and the two racks 13 are located on either side of the support plate 11. The support shaft 22, which has a smaller diameter than the extrusion wheel 2, supports the right side of the extrusion wheel 2 and avoids the fixing mechanism 5 located on the right side of the support plate 3, thereby preventing the extrusion wheel 2 from being obstructed by the fixing mechanism 5 during movement.

[0035] The inner wall of the sliding frame 42 is provided with a mounting groove 43, in which a plurality of rolling wheels 44 are rotatably mounted. The rolling wheels 44 are located above the sliding rods 12. The rolling wheels 44 cooperate with the sliding rods 12 to complete the sliding connection between the sliding frame 42 and the two sliding rods 12. The rolling friction between the rolling wheels 44 and the sliding rods 12 replaces the sliding friction between the sliding frame 42 and the sliding rods 12, which can effectively reduce friction and make the movement of the pushing frame 42 smoother.

[0036] The connecting plate 41 gradually tilts upward from front to back. When the pusher 4 is pushed, the gradually tilted connecting plate 41 exerts an oblique downward force on the squeezing wheel 2, causing the squeezing wheel 2 to move backward. When the ink burst test is performed on the cigarette paper 50, the squeezing wheel 2 is subjected to downward pressure, thereby pressing the squeezing wheel 2 against the cigarette paper 50 and causing the rolling wheel 44 to press against the sliding rod 12.

[0037] The sides of the support plate 11 are detachably mounted with a stopper 120 at both ends of the sliding rod 12. The maximum sliding position of the sliding frame 42 is limited by the stopper 120 to prevent the sliding frame 42 from sliding out of the range of the sliding rod 12 and causing the sliding frame 42 to fall.

[0038] A stop bar 121 is fixedly mounted on the right side of the upper end surface of the support plate 3. A fixing mechanism 5 for securing the cigarette paper 50 is fixedly mounted on the stop bar 121. This fixing mechanism 5 secures the cigarette paper 50 to the support plate 3, preventing it from sliding during testing. The stop bar 121 also defines the position of the cigarette paper 50. During use, the edge of the cigarette paper 50, cut to a specific size, is placed against the stop bar 121 and then secured with the fixing mechanism 5.

[0039] The fixing mechanism 5 comprises two inverted L-shaped fixing blocks 51. Each fixing block 51 has a through-hole through which a lifting rod 52 is inserted. A fixing head 53 is fixedly mounted at the lower end of the lifting rod 52. The diameter of the fixing head 53 is larger than that of the lifting rod 52. A compression spring 520 is sleeved between the fixing blocks 51 and the fixing head 53. A pull ring 54 is detachably mounted on the upper end of the lifting rod 52. The compression spring 520 presses the fixing head 53 against the cigarette paper 50, securing it to the support plate 3. The structure is simple and easy to use.

[0040] The lower end of the projection 31 is provided with a transverse projection 32. The support plate 11 has multiple transverse positioning grooves 320 defined within the strip-shaped groove 30. Because the depth of the strip-shaped grooves 30 increases uniformly from left to right in a stepped pattern, once the projections 32 are engaged with the corresponding positioning grooves 320, the support plate 3 is prevented from moving laterally to the left without being lifted.

[0041] An L-shaped block 6 is fixedly mounted on the front end of the base plate 10. The L-shaped block 6 has a threaded hole into which a fixing head 61 is screwed. In actual use, the fixing head 61 and the L-shaped block 6 can be used to fix the test device to the edge of the laboratory table to prevent the test device from moving during use.

[0042] In this embodiment, during use, the cigarette paper 50 is pre-folded and placed on the support plate 3 and secured with the fixing mechanism 5. The support plate 3 is then placed on the sliding plate 12. Pressure is then applied diagonally downward to the connecting plate 41. The meshing of the gear 21 and the rack 13 causes the squeezing wheel 2 to roll and move forward, squeezing the cigarette paper 50 placed on the support plate 3 and performing the ink burst test.

[0043] After the cigarette paper 50 is completely squeezed by the squeezing wheel 2, the pushing frame 4 is pushed in the reverse direction to reset the squeezing wheel 2;

[0044] If no ink burst occurs during one test, the support plate 3 can be lifted upward to separate the support plate 3 from the sliding plate 12, and then the support plate 3 is moved to the left by one step. Then, the pull rod 17 is pulled again to complete a second ink burst test on the cigarette paper.

[0045] Repeat the above steps until ink bursts appear at the creases of the cigarette paper.

[0046] The above describes in detail the gradient-push-type cigarette paper ink burst test device 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. It should be noted that those skilled in the art will readily appreciate that various improvements and modifications to the present invention can be made without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims.
