Description

Technical Field

[0001] The present invention belongs to the technical field of detection equipment, and particularly relates to a gradient rolling ink explosion testing device for cigarette paper. Background Art

[0002] With the increasingly wide application of cigarette papers such as base paper, composite paper and transfer paper in packaging, whether the cigarette paper can meet the printing requirements in specific uses of packaging is also a very important performance requirement.

[0003] When cigarette paper is used for packaging, there is often a phenomenon of ink explosion after folding. At present, the common method is to manually fold the cigarette paper and then observe the ink explosion situation of the dark line for detection and judgment. However, the folding force of each person on the cigarette paper is different, resulting in large differences in the detection results and being unable to accurately judge whether the cigarette paper is qualified. Summary of the Invention

[0004] The purpose of the present invention is to provide a gradient rolling ink explosion testing device for cigarette paper. Through the mutual cooperation of a moving plate provided with a stepped strip-shaped groove, a support plate with a stepped convex block on the lower end surface and a pressing wheel, the height difference between the support plate and the pressing wheel can be adjusted, so as to perform an extrusion ink explosion test on the cigarette paper after preliminary folding. According to the position of the support plate when the cigarette paper explodes with ink, the ink explosion limit of the cigarette paper can be obtained, and the detection accuracy is high; through the mutual cooperation of an incomplete gear, a rack, a controllable motor and a first compression spring, the semi-automation of the test is realized, and the automatic reset after one test is completed is realized, which is convenient for the second test.

[0005] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0006] A gradient rolling type cigarette paper ink explosion testing device comprises a conveying mechanism and an extrusion wheel, the conveying mechanism comprises a bottom bracket, two sliding rods, a sliding plate and a rack, the two sliding rods are transversely fixedly installed on the bottom bracket, the sliding plate is slidably installed between the two sliding rods, the rack is transversely fixedly installed on the sliding plate, a strip groove is transversely opened on the upper end surface of the sliding plate, the depth of the strip groove is uniformly deepened from right to left and is in a stepped shape, a support plate is detachably installed on the sliding plate, a convex block is transversely arranged on the lower end surface of the support plate, the cross section of the convex block is in a stepped shape with a thickness uniformly deepened from right to left, the extrusion wheel is rotatably installed on the sliding rod and is located on one side above the sliding plate, the extrusion wheel An incomplete gear is fixedly installed on the side of the wheel, and the incomplete gear is meshed with the rack. The diameter of the involute of the incomplete gear is equal to the diameter of the outer contour of the extrusion wheel. An avoidance groove is axially provided on the outer wall of the extrusion wheel, and the avoidance groove corresponds to the toothless part of the incomplete gear. A controllable motor and a reduction gear box are also installed on the bottom bracket, and the output shaft of the controllable motor is connected to the extrusion wheel through the reduction gear box. A fixing seat is also fixedly installed on the lower end surface of the sliding plate, and a guide rod is fixedly installed on the fixing seat. A block seat is also fixedly installed on the bottom bracket, and a guide hole is provided on the block seat. The free end of the guide rod is inserted into the guide hole, and a first compression spring is sleeved on the guide rod between the fixing seat and the block seat.

[0007] It is further defined that the controllable motor is a servo motor. With such a structural design, the servo motor runs more smoothly when rotating at a low speed compared to the stepper motor, and is more suitable for the low-speed operation condition of the device.

[0008] It is further defined that the inner wall of the sliding rod is provided with a sliding groove, and the side walls on both sides of the sliding plate are rotatably mounted with a plurality of rolling wheels, and the rolling wheels are located in the sliding groove. Such a structural design completes the sliding connection between the sliding plate and the two sliding rods through the cooperation between the rolling wheels and the sliding groove, and utilizes the rolling friction between the rolling wheels and the sliding groove to replace the sliding friction between the sliding plate and the sliding rod, which can effectively reduce the friction force and make the movement of the sliding plate smoother.

[0009] It is further defined that the two sliding rods have a first fixed rod fixedly mounted on one end and a second fixed rod detachably mounted on the other end. With this structural design, the maximum sliding position of the sliding plate is limited by the first fixed rod and the second fixed rod, thereby preventing the sliding plate from sliding out of the range of the sliding rod and causing the sliding plate to fall.

[0010] Further defined, a stop bar is fixedly installed on the left side of the upper end surface of the support plate, and a fixing mechanism for fixing the cigarette paper is fixedly installed on the stop bar. With such a structural design, the cigarette paper can be fixed on the support plate through the fixing mechanism, preventing the cigarette paper from sliding during the test; the stop bar can limit the position of the cigarette paper. When in use, the edge of the cigarette paper cut into a specific size is abutted against the stop bar, and then fixed with the fixing mechanism.

[0011] Further defined, the fixing mechanism includes two inverted L-shaped fixing blocks. A through hole is provided in the fixing block, and a lifting rod is inserted through the through hole. A fixing head is fixedly installed at the lower end of the lifting rod, and the diameter of the fixing head is larger than that of the lifting rod. A second compression spring is sleeved on the lifting rod between the fixing block and the fixing head, and a pull ring is detachably installed at the upper end of the lifting rod. With such a structural design, the cigarette paper is fixed on the support plate by the pressing of the second compression spring on the fixing head, with a simple structure and convenient use.

[0012] Further defined, a support shaft is integrally formed at the left end of the extrusion wheel. The support shaft is coaxial with the extrusion wheel, and the diameter of the support shaft is smaller than that of the extrusion wheel. A mounting plate is fixedly installed on the sliding rod. The support shaft and the extrusion wheel are rotatably installed between the two mounting plates. There are two incomplete gears and two racks respectively, and the two racks are located on both sides of the sliding plate. With such a structural design, the left side of the extrusion wheel is supported by the support shaft with a diameter smaller than that of the extrusion wheel, and at the same time, the fixing mechanism on the left side of the support plate is avoided. It can prevent the support plate provided with the fixing mechanism from being blocked by the extrusion wheel during the movement process.

[0013] Further defined, a convex strip is transversely provided on the lower end surface of the convex block, and a plurality of positioning grooves are transversely opened in the sliding plate in the strip-shaped groove. With such a structural design, since the depth dimension of the strip-shaped groove gradually deepens uniformly from right to left and is in a stepped shape, after the convex platform is clamped into the corresponding positioning groove, it can prevent the support plate from moving horizontally to the left without being lifted.

[0014] Further defined, an L-shaped clamping block is fixedly installed at the front end of the bottom bracket, and a threaded hole is provided in the L-shaped clamping block, and a locking head is screwed in the threaded hole. With such a structural design, during the actual use process, the locking head and the L-shaped clamping block can be used to fix the testing device on the edge of the experimental table, preventing the testing device from moving during the use process.

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

[0016] 1. Through the cooperation of the moving plate with stepped strip-shaped grooves, the support plate with stepped bumps on the lower end surface, and the extrusion wheel, the height difference between the support plate and the extrusion wheel can be adjusted, so as to conduct an extrusion ink explosion test on the preliminarily folded cigarette paper. According to the position of the support plate when the cigarette paper explodes with ink, the ink explosion limit of the cigarette paper can be obtained, and the detection accuracy is high;

[0017] 2. Through the cooperation of the incomplete gear, the rack, the controllable motor, and the first compression spring, the semi-automation of the test is realized, and the automatic reset after one test is completed is realized, which is convenient for the secondary test;

[0018] 3. Through the cooperation of the incomplete gear, the rack, and the extrusion wheel with an avoidance groove, the influence of the sliding friction between the extrusion wheel and the cigarette paper during the reset process of the sliding plate on the test result can be avoided;

[0019] 4. Through the mutual matching of the convex strip and the multiple positioning grooves, after the convex platform is clamped into the corresponding positioning groove, the support plate can be prevented from moving horizontally to the left without being lifted.

[0034] 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 description of the drawings or the specification, similar or identical parts are denoted by the same reference numerals, and the implementation manners not shown or described in the drawings are those well known to those of ordinary skill in the art. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "rear", etc., are only references to the directions in the drawings and are not intended to limit the protection scope of the present invention.

[0035] As Figures 1 to 5As shown, a gradient rolling type cigarette paper ink explosion testing device of the present invention comprises a conveying mechanism 1 and an extrusion wheel 2, wherein the conveying mechanism 1 comprises a bottom bracket 10, two sliding rods 11, a sliding plate 12 and a rack 13, wherein the two sliding rods 11 are transversely fixedly installed on the bottom bracket 10, the sliding plate 12 is slidably installed between the two sliding rods 11, the rack 13 is transversely fixedly installed on the sliding plate 12, a strip groove 30 is transversely opened on the upper end surface of the sliding plate 12, the depth dimension of the strip groove 30 is uniformly deepened from right to left and is in a stepped shape, a support plate 3 is detachably installed on the sliding plate 12, a convex block 31 is transversely arranged on the lower end surface of the support plate 3, and the cross section of the convex block 31 is in a stepped shape with a thickness uniformly deepened from right to left, the extrusion wheel 2 is rotatably installed on the sliding rod 11 and is located on one side above the sliding plate 12, An incomplete gear 21 is fixedly installed on the side of the pressing wheel 2, and the incomplete gear 21 is meshed with the rack 13. The diameter of the involute of the incomplete gear 21 is equal to the diameter of the outer contour of the extrusion wheel 2. An avoidance groove 20 is axially opened on the outer wall of the extrusion wheel 2, and the avoidance groove 20 corresponds to the toothless part of the incomplete gear 21. A controllable motor 14 and a reduction box 15 are also installed on the bottom bracket 10. The output shaft of the controllable motor 14 is connected to the extrusion wheel 2 through the reduction box 15. A fixed seat 4 is also fixedly installed on the lower end surface of the sliding plate 12, and a guide rod 41 is fixedly installed on the fixed seat 4. A stopper 42 is also fixedly installed on the bottom bracket 10, and a guide hole is opened on the stopper 42. The free end of the guide rod 41 is inserted into the guide hole, and a first compression spring 43 is sleeved on the guide rod 41 between the fixed seat 4 and the stopper 42.

[0036] The controllable motor 14 is a servo motor. Compared with a stepper motor, a servo motor runs more smoothly when rotating at a low speed, and is more suitable for the low-speed operation condition of the device.

[0037] A slide groove 110 is provided on the inner wall of the sliding rod 11, and a plurality of rolling wheels 120 are rotatably mounted on the side walls of both sides of the sliding plate 12, and the rolling wheels 120 are located in the slide groove 110. The sliding connection between the sliding plate 12 and the two sliding rods 11 is completed by the mutual cooperation between the rolling wheels 120 and the slide groove 110, and the rolling friction between the rolling wheels 120 and the slide groove 110 is used instead of the sliding friction between the sliding plate 12 and the sliding rod 11, which can effectively reduce the friction force and make the movement of the sliding plate 12 smoother.

[0038] The two sliding rods 11 have a first fixed rod 111 fixedly mounted on one end and a second fixed rod 112 detachably mounted on the other end. The first fixed rod 111 and the second fixed rod 112 limit the maximum sliding position of the sliding plate 12 to prevent the sliding plate 12 from sliding out of the range of the sliding rod 11 and causing the sliding plate 12 to fall.

[0039] On the left side of the upper end surface of the support plate 3, a stop bar 121 is fixedly installed, and a fixing mechanism 5 for fixing the cigarette paper 50 is fixedly installed on the stop bar 121. The cigarette paper 50 can be fixed on the support plate 3 through the fixing mechanism 5 to prevent the cigarette paper 50 from sliding during the test; the stop bar 121 can limit the position of the cigarette paper 50. When in use, the edge of the cigarette paper 50 cut into a specific size is abutted against the stop bar 121, and then fixed with the fixing mechanism 5.

[0040] The fixing mechanism 5 includes two inverted L-shaped fixing blocks 51. Through holes are formed in the fixing blocks 51, and a lifting rod 52 is inserted through the through holes. A fixing head 53 is fixedly installed at the lower end of the lifting rod 52. The diameter of the fixing head 53 is larger than the diameter of the lifting rod 52. A second compression spring 520 is sleeved on the lifting rod 52 between the fixing block 51 and the fixing head 53. A pull ring 54 is detachably installed at the upper end of the lifting rod 52. The cigarette paper 50 is fixed on the support plate 3 by the pressing of the second compression spring 520 on the fixing head 53, with a simple structure and convenient use.

[0041] 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 the diameter of the support shaft 22 is smaller than the diameter of the extrusion wheel 2. A mounting plate 7 is fixedly installed on the sliding rod 11. The support shaft 22 and the extrusion wheel 2 are rotatably installed between the two mounting plates 7. There are two incomplete gears 21 and two racks 13 respectively. The two racks 13 are located on both sides of the sliding plate 12. The left side of the extrusion wheel 2 is supported by the support shaft 22 with a diameter smaller than that of the extrusion wheel 2, and at the same time, the fixing mechanism 5 on the left side of the support plate 3 is avoided. It can prevent the support plate 3 provided with the fixing mechanism 5 from being blocked by the extrusion wheel 2 during the movement.

[0042] A convex strip 32 is transversely arranged on the lower end surface of the convex block 31. A plurality of positioning grooves 320 are transversely formed in the sliding plate 12 within the strip-shaped groove 30. Since the depth dimension of the strip-shaped groove 30 gradually deepens uniformly from right to left and is in a stepped shape, after the convex platform 32 is clamped into the corresponding positioning groove 320, it can prevent the support plate 3 from moving horizontally to the left without being lifted.

[0043] An L-shaped clamping block 6 is fixedly installed at the front end of the bottom bracket 10. A threaded hole is formed in the L-shaped clamping block 6, and a locking head 61 is screwed in the threaded hole. During the actual use process, the locking head 61 and the L-shaped clamping block 6 can be used to fix the test device on the edge of the experimental table to prevent the test device from moving during use.

[0044] In this embodiment, when in use, the cigarette paper 50 is pre-folded and then placed on the support plate 3, fixed with the fixing mechanism 5, then the support plate 3 is placed on the sliding plate 12, and then the controllable motor 14 is started. The extrusion wheel 2 is driven to rotate counterclockwise by the controllable motor 14 and the reduction gearbox 15 (takingFigure 1 For example), then through the meshing of the incomplete gear 21 and the rack 13, the sliding plate 12 is driven to move backward at the same linear velocity as the outer contour of the extrusion wheel 2 against the elastic force of the first compression spring 43, thereby driving the support plate 3 arranged on the sliding plate 12 to move backward, and further enabling the cigarette paper 50 to enter below the extrusion wheel 2 and be extruded by the extrusion wheel 2 for ink explosion testing;

[0045] When the incomplete gear 21 rotates to disengage from the rack 13, the sliding plate 12 resets under the action of the first compression spring 43, that is, moves forward. During this process, the extrusion wheel 2 continues to rotate until the extrusion wheel 2 rotates one full circle, and then the controllable motor 14 automatically shuts down;

[0046] During the reset process of the sliding plate 12, the avoidance groove 20 of the extrusion wheel 2 faces the cigarette paper 50 and does not contact the cigarette paper 50, so as to prevent the extrusion wheel 2 from contacting the cigarette paper 50 during the reset process of the sliding plate 12, generating relative friction and affecting the test results;

[0047] If no ink explosion phenomenon occurs in one experiment, the support plate 3 can be lifted upward so that the support plate 3 is separated from the sliding plate 12, then the support plate 3 is moved one step to the right, and then the controllable motor 14 is started again to complete the secondary ink explosion test on the cigarette paper;

[0048] Repeat the above steps until an ink explosion phenomenon appears at the crease of the cigarette paper.

[0049] The above has introduced in detail a gradient rolling type ink explosion testing device for cigarette paper provided by the present invention. The description of the specific embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
