Description

Technical Field

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

[0002] When cigarette paper is packaged, ink often bursts after being folded. The current practice is to manually fold the cigarette paper along the crease and observe the dark line for ink bursting to conduct inspection and judgment. However, the strength with which each person folds the cigarette paper varies, resulting in large differences in the test results, making it impossible to accurately determine whether the cigarette paper is qualified. Summary of the Invention

[0003] The purpose of the present invention is to provide a chute-type cigarette paper ink burst testing device to solve the problem that the existing ink burst detection method cannot accurately determine whether the cigarette paper is qualified.

[0004] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0005] A chute-type cigarette paper ink explosion testing device comprises a transmission mechanism, a fixing mechanism and an extrusion mechanism, wherein the extrusion mechanism comprises a supporting frame, a fixing frame, an adjusting frame, an adjusting component and a motor, wherein the supporting frame and the fixing frame are fixedly connected, a lower roller is rotatably mounted on the fixing frame, a rotating shaft is rotatably mounted on the fixing frame, the motor is transmission-connected to the rotating shaft, a first transmission gear is fixedly mounted on the rotating shaft, a second transmission gear and a third transmission gear are rotatably mounted on the fixing frame, the first transmission gear and the second transmission gear are meshed, the second transmission gear and the third transmission gear are meshed, the third transmission gear is fixedly connected to the lower roller, a first articulated frame is hinged on the fixing frame, and a middle portion of the articulated connection between the fixing frame and the first articulated frame is hinged. The center point coincides with the central axis of the third transmission gear, and the fourth transmission gear and the fifth transmission gear are also rotatably installed on the first articulated frame. The third transmission gear and the fourth transmission gear are meshed, and the fourth transmission gear and the fifth transmission gear are meshed. A second articulated frame is hinged between the adjusting frame and the first articulated frame, and the center point of the hinge of the first articulated frame and the second articulated frame coincides with the central axis of the fifth transmission gear. The adjusting frame is slidably connected to the supporting frame, and an upper roller is rotatably installed on the adjusting frame. The second articulated frame also rotatably installs a sixth transmission gear, and the sixth transmission gear is fixedly connected to the upper roller. The fifth transmission gear is meshed with the sixth transmission gear, and the center point of the hinge of the adjusting frame and the second articulated frame coincides with the sixth transmission gear. The center axis of the upper roller coincides with the center axis of the upper roller and is parallel to the center axis of the lower roller, the support frame includes a mounting plate, the adjusting component includes a connecting piece and an inverted U-shaped sliding frame, the connecting piece is fixedly connected to the adjusting frame, the connecting piece has a rectangular cross section, the mounting plate is provided with a rectangular hole, the connecting piece is slidably installed in the rectangular hole, the sliding frame is slidably installed on the mounting plate, the sliding frame is located above the connecting piece, and a positioning rod is fixedly installed on the sliding frame, the side surface of the connecting piece is inclined to open a strip hole, the positioning rod is passed through the strip hole, and sliding blocks are integrally formed on both sides of the sliding frame, the mounting plate is fixedly installed with strip blocks on both sides of the sliding frame, and the strip block is provided with a sliding groove on the side close to the sliding frame. The sliding block is located in the sliding groove, and rectangular grooves are provided at both ends of the sliding frame. The sliding frame is provided with a connecting hole at the bottom of the rectangular groove, and a lifting rod is passed through the connecting hole. A plurality of clips are integrally formed on the lower end of the lifting rod, and the mounting plate is fixedly installed with fixing strips on both sides of the connecting piece, and a plurality of notches are evenly provided on the fixing strips. The clips are located in the notches, and a stop block is integrally formed on the upper end of the lifting rod. The outer side of the stop block is provided with an inclined surface inclined inward from top to bottom, and the sliding frame is slidably installed with a push block in the rectangular groove, and the inner end of the push block rests on the inclined surface of the stop block. The sliding frame is also fixedly installed with a fixed block in the rectangular groove, and the fixed block is located above the stop block and the push block, and an elastic element is installed between the fixed block and the stop block.

[0006] Furthermore, the bar block is provided with a scale, and the sliding frame is fixedly mounted with a pointer above the scale. This structural design allows the scale and the pointer to cooperate with each other to display the adjusted position of the adjustment frame, that is, the distance between the lower roller and the upper roller at that time can be obtained by the number indicated by the pointer on the scale, making adjustment more convenient.

[0007] It is further defined that the upper end surface of the stop block is provided with a first groove, the lower end surface of the fixed block is provided with a second groove, the elastic element is a C-shaped spring piece, the elastic element is located within the first groove and the second groove, the free ends of both ends of the elastic element are provided with bar-shaped clamping blocks, the stop block and the fixed block are provided with bar grooves, and the bar clamping blocks are clamped within the bar grooves. This structural design, in which the elastic element is a C-shaped spring piece, is simple in structure and easy to install; the C-shaped spring piece is fixed within the first groove and the second groove, and the ends are fixed by the mutual matching of the bar clamping blocks and the bar groove, thus ensuring a stable installation.

[0008] Furthermore, the push block is provided with limit bars at both ends, the fixed block has a first limit slot on its lower end surface, the sliding frame has a second limit slot within the rectangular slot, and the limit bars are located within the first and second limit slots, respectively. This structural design, through the interaction between the limit bars and the first and second limit slots, defines the limit position of the push block, preventing the push block from completely disengaging from the rectangular slot and causing it to fall.

[0009] The adjustment frame further comprises a connecting rod, the connecting member being fixedly connected to the connecting rod, the support frame being provided with a slot, and the end of the connecting rod being inserted into the slot. This structural design, through the interaction between the connecting rod and the slot, limits the freedom of movement of the adjustment frame, so that the adjustment frame can only move up and down within a certain range, resulting in a simple structure and easy use.

[0010] Furthermore, the ratio of the number of teeth of the third transmission gear to the number of teeth of the sixth transmission gear is equal to the ratio of the diameter of the lower roller to the diameter of the upper roller. This structural design ensures that the linear speeds of the lower roller and the upper roller are equal when they rotate.

[0011] Furthermore, the third transmission gear and the sixth transmission gear have the same number of teeth, and the lower roller and the upper roller have the same diameter. This structural design allows the third transmission gear and the sixth transmission gear to be interchangeable with each other, and the lower roller and the upper roller to be interchangeable with each other, thereby enhancing practicality.

[0012] The invention further provides that the conveying mechanism is located on one side of the extrusion mechanism, the conveying mechanism comprising a bottom bracket, the motor fixedly mounted on the bottom bracket, two first transmission rollers rotatably mounted on the bottom bracket, a transmission belt wound around the two first transmission rollers, a seventh transmission gear fixedly mounted on the rotating shaft, an eighth transmission gear rotatably mounted on the bottom bracket, the eighth transmission gear fixedly mounted on one of the first transmission rollers, and a timing belt wound between the seventh and eighth transmission gears. With this structural design, while the motor drives the lower and upper rollers to rotate via the rotating shaft, the transmission belt is simultaneously driven to rotate via the timing belt, so that after the preliminarily folded cigarette paper is secured to the transmission belt by the securing mechanism, it is driven by the transmission belt to enter between the lower and upper rollers for testing, with the transmission belt, lower roller, and upper roller rotating synchronously. Furthermore, by setting the diameters of the first transmission gear, third transmission gear, sixth transmission gear, lower roller, upper roller, seventh transmission gear, eighth transmission gear, and first transmission roller, the linear speeds of the transmission belt, lower roller, and upper roller are equal.

[0013] The fixing mechanism further defines that the fixing mechanism includes a mounting frame on which two or more second transmission rollers are rotatably mounted, each of which is wound with a fixed belt, the fixed belt being positioned above the transmission belt, the lower end surface of the fixed belt being parallel to the upper end surface of the transmission belt. A ninth transmission gear is rotatably mounted on the mounting frame and fixedly connected to one of the second transmission rollers. A tenth transmission gear is rotatably mounted on the bottom bracket and meshes with the tenth transmission gear. The tenth transmission gear is fixedly connected to one of the first transmission rollers. The ninth and tenth transmission gears have the same number of teeth, and the first and second transmission rollers have the same diameter. With this structural design, after the motor is started, driven by the rotating shaft, the lower roller, upper roller, transmission belt, and fixed belt rotate synchronously at the same linear speed, thereby driving the preliminarily folded cigarette paper to be fixed between the fixed belt and the transmission belt. The transmission belt then moves leftward at the same speed as the linear speed of the lower roller, entering between the lower and upper rollers to complete the ink burst detection.

[0014] It is further defined that there are three second transmission rollers and one end of the fixed belt is tilted upward. Such a structural design makes it more convenient to insert folded cigarette paper between the fixed belt and the transmission belt.

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

[0016] 1. The distance between the lower roller and the upper roller is adjusted by adjusting the components, so that the ink burst test can be performed on the preliminarily folded cigarette paper. The ink burst limit of the cigarette paper can be obtained based on the distance between the upper roller and the lower roller used during the ink burst, with high detection accuracy.

[0017] 2. The positioning rod cooperates with the oblique strip hole on the side of the connecting piece, so that when the sliding frame equipped with the positioning rod is dragged horizontally, the sliding frame can drive the connecting piece to move up and down, and then drive the adjustment frame to move up and down, thereby completing the adjustment of the distance between the lower roller and the upper roller. The clamping strip and the notch cooperate with each other to complete the fixation between the sliding frame and the support frame, preventing the upper roller from moving upward under the reaction force of the cigarette paper when squeezing the preliminarily folded cigarette paper, thereby changing the distance between the upper roller and the lower roller and affecting the test effect;

[0018] 3. The adjustment position of the adjustment frame is displayed through the cooperation of the pointer and the scale. That is, the distance between the lower roller and the upper roller at this time is obtained through the reading of the pointer on the scale, making the adjustment more convenient.

[0019] 4. The fixed frame and the adjustment frame are hinged by the first hinge frame and the second hinge frame. The third transmission gear, the fourth transmission gear, the fifth transmission gear and the sixth transmission gear are meshed in sequence. When the adjustment frame moves up and down under the action of the adjustment component, the meshing relationship between the third transmission gear, the fourth transmission gear, the fifth transmission gear and the sixth transmission gear does not change. That is, when the distance between the lower roller and the upper roller changes, the lower roller and the upper roller can still maintain synchronous motion with the same linear speed and opposite rotation directions.

[0020] 5. The initially folded cigarette paper is driven by a transmission belt to pass between the upper roller and the lower roller, where it is squeezed to complete the ink burst test. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0052] like Figures 1 to 14 As shown, a chute-type cigarette paper ink burst testing device of the present invention includes a conveying mechanism 1, a fixing mechanism 2 and a squeezing mechanism 3. The squeezing mechanism 3 includes a supporting frame 30, a fixing frame 31, an adjusting frame 32, an adjusting component and a motor 34. The supporting frame 30 and the fixing frame 31 are fixedly connected. A lower roller 310 is rotatably mounted on the fixing frame 31.

[0053] like Figure 1 and Figure 6 As shown, a rotating shaft 311 is rotatably installed on the fixed frame 31, and the motor 34 is transmission-connected to the rotating shaft 311. A first transmission gear 51 is fixedly installed on the rotating shaft 311. A second transmission gear 52 and a third transmission gear 53 are rotatably installed on the fixed frame 31. The first transmission gear 51 and the second transmission gear 52 are meshed, and the second transmission gear 52 and the third transmission gear 53 are meshed. The third transmission gear 53 is fixedly connected to the lower roller 310. A first articulated frame 530 is hinged on the fixed frame 31. The center point of the articulation between the fixed frame 31 and the first articulated frame 530 coincides with the central axis of the third transmission gear 53. A fourth transmission gear 54 and a fifth transmission gear 55 are also rotatably installed on the first articulated frame 530. The third transmission gear 53 and the fourth transmission gear 54 are meshed. 54 is engaged, the fourth transmission gear 54 is engaged with the fifth transmission gear 55, the second articulated frame 550 is hinged between the adjustment frame 32 and the first articulated frame 530, the center point of the hinge between the first articulated frame 530 and the second articulated frame 550 coincides with the central axis of the fifth transmission gear 55, the adjustment frame 32 is slidably connected to the support frame 30, the upper roller 320 is rotatably mounted on the adjustment frame 32, and the sixth transmission gear 56 is also rotatably mounted on the second articulated frame 550, the sixth transmission gear 56 is fixedly connected to the upper roller 320, the fifth transmission gear 55 is engaged with the sixth transmission gear 56, the center point of the hinge between the adjustment frame 32 and the second articulated frame 550 coincides with the central axis of the sixth transmission gear 56, and the central axis of the upper roller 320 is parallel to the central axis of the lower roller 310;

[0054] like Figures 3 to 13As shown, the support frame 30 includes a mounting plate 4, and the adjusting component includes a connecting piece 331 and an inverted U-shaped sliding frame 7. The connecting piece 331 is fixedly connected to the adjusting frame 32. The cross section of the connecting piece 331 is rectangular. A rectangular hole 40 is provided on the mounting plate 4. The connecting piece 331 is slidably installed in the rectangular hole 40. The sliding frame 7 is slidably installed on the mounting plate 4. The sliding frame 7 is located above the connecting piece 331. A positioning rod 71 is fixedly installed on the sliding frame 7. A strip hole 710 is obliquely provided on the side of the connecting piece 331. The positioning rod 71 is passed through the strip hole 710. Sliding blocks 72 are integrally formed on both sides of the sliding frame 7. The mounting plate 4 is fixedly installed with strip blocks 42 on both sides of the sliding frame 7. A sliding groove is provided on the side of the strip block 42 close to the sliding frame 7. The sliding block 72 is located in the sliding groove. Rectangular grooves are provided at both ends of the sliding frame 7 730, the sliding frame 7 is provided with a connecting hole at the bottom of the rectangular groove 730, and a lifting rod 731 is passed through the connecting hole. A plurality of clips 7310 are integrally formed at the lower end of the lifting rod 731, and the mounting plate 4 is fixedly installed with fixing strips 41 on both sides of the connecting piece 331. A plurality of notches 410 are evenly provided on the fixing strips 41, and the clips 7310 are located in the notches 410. A stop block 732 is integrally formed at the upper end of the lifting rod 731, and an outer side of the stop block 732 is provided with an inclined surface inclined inward from top to bottom. The sliding frame 7 is slidably installed with a push block 74 in the rectangular groove 730, and the inner end of the push block 74 rests on the inclined surface of the stop block 732. The sliding frame 7 is also fixedly installed with a fixing block 75 in the rectangular groove 730. The fixing block 75 is located above the stop block 732 and the push block 74, and an elastic element 76 is installed between the fixed block 75 and the stop block 732.

[0055] The bar block 42 is provided with a scale, and a pointer 420 is fixedly mounted above the scale on the sliding frame 7. The scale and pointer 420 cooperate to display the adjusted position of the adjustment frame 32. That is, the distance between the lower roller 310 and the upper roller 320 at that time is obtained by the number indicated by the pointer 420 on the scale, making adjustment more convenient.

[0056] The upper surface of the stopper 732 defines a first groove 761, while the lower surface of the fixed block 75 defines a second groove. The elastic element 76 is a C-shaped spring clip, located within the first and second grooves. Each free end of the elastic element is provided with a bar-shaped retaining block 760. Both the stopper 732 and the fixed block 75 define a bar groove, into which the bar retaining block 760 engages. The C-shaped spring clip of the elastic element 76 offers a simple structure and easy installation. The C-shaped spring clip is secured within the first and second grooves, with its ends secured by the mating of the bar retaining block 760 and the bar groove, ensuring a secure installation.

[0057] Limit bars 740 are provided at both the upper and lower ends of the push block 74. A first limiting groove 741 is defined on the lower end surface of the fixed block 75. A second limiting groove 742 is defined within the rectangular groove 730 of the sliding frame 7. The limiting bars 740 are positioned within the first limiting groove 741 and the second limiting groove 742, respectively. The interaction of the limiting bars 740 with the first limiting groove 741 and the second limiting groove 742 defines the limit position of the push block 74, preventing the push block 74 from completely disengaging from the rectangular groove 730 and potentially falling.

[0058] The adjustment frame 32 includes a connecting rod 6, a connecting member 331 fixedly connected to the connecting rod 6, and a slot 60 formed in the support frame 30. The end of the connecting rod 6 is inserted into the slot 60. The interaction between the connecting rod 6 and the slot 60 limits the freedom of movement of the adjustment frame 32, so that the adjustment frame 32 can only move up and down within a certain range. This structure is simple and easy to use.

[0059] The ratio of the number of teeth of the third transmission gear 53 to the number of teeth of the sixth transmission gear 56 is equal to the ratio of the diameter of the lower roller 310 to the diameter of the upper roller 320. This ensures that the linear speeds of the lower roller 310 and the upper roller 320 are equal when they rotate.

[0060] The third transmission gear 53 and the sixth transmission gear 56 have the same number of teeth, and the lower roller 310 and the upper roller 320 have the same diameter. The third transmission gear 53 and the sixth transmission gear 56 are interchangeable with each other, and the lower roller 310 and the upper roller 320 are interchangeable with each other, which makes them more practical.

[0061] The conveying mechanism 1 is located on one side of the extrusion mechanism 3. The conveying mechanism 1 includes a bottom bracket 10, and the motor 34 is fixedly mounted on the bottom bracket 10. Two first transmission rollers 11 are rotatably mounted on the bottom bracket 10, and a transmission belt 12 is wound around the two first transmission rollers 11. The seventh transmission gear 57 is also fixedly mounted on the rotating shaft 311. The eighth transmission gear 58 is rotatably mounted on the bottom bracket 10, and the eighth transmission gear 58 is fixedly mounted on one of the first transmission rollers 11. A synchronous belt 570 is wound between the seventh transmission gear 57 and the eighth transmission gear 58. While the motor 34 drives the lower roller 310 and the upper roller 320 to rotate through the rotating shaft 311, the transmission belt 12 is driven to rotate synchronously through the synchronous belt 570, so that the cigarette paper that has been preliminarily folded is fixed on the transmission belt 12 by the fixing mechanism 2, and then driven by the transmission belt 12 to enter between the lower roller 310 and the upper roller 320 for testing. The transmission belt 12, the lower roller 310 and the upper roller 320 operate synchronously. At the same time, by setting the diameters of the first transmission gear 51, the third transmission gear 53, the sixth transmission gear 56, the lower roller 310, the upper roller 320, the seventh transmission gear 57, the eighth transmission gear 58 and the first transmission roller 11, the linear speeds of the transmission belt 12, the lower roller 310 and the upper roller 320 are equal.

[0062] The fixing mechanism 2 includes a mounting frame 20, on which more than two second transmission rollers 21 are rotatably mounted, and a fixed belt 22 is wound around all the second transmission rollers 21. The fixed belt 22 is located above the transmission belt 12, and the lower end surface of the fixed belt 22 is parallel to the upper end surface of the transmission belt 12. A ninth transmission gear 59 is rotatably mounted on the mounting frame 20, and the ninth transmission gear 59 is fixedly connected to one of the second transmission rollers 21. A tenth transmission gear 510 is rotatably mounted on the bottom bracket 10, and the ninth transmission gear 59 is meshed with the tenth transmission gear 510. The tenth transmission gear 510 is fixedly connected to one of the first transmission rollers 11. The ninth transmission gear 59 and the tenth transmission gear 510 have the same number of teeth, and the diameters of the first transmission roller 11 and the second transmission roller 21 are the same. After the motor 34 is started, driven by the rotating shaft 311, the lower roller 310, the upper roller 320, the transmission belt 12 and the fixed belt 22 rotate synchronously at the same linear speed, thereby driving the preliminarily folded cigarette paper to be fixed between the fixed belt 22 and the transmission belt 12. The transmission belt 12 moves to the left at the same speed as the linear speed of the lower roller 310, enters between the lower roller 310 and the upper roller 320, and completes the ink burst detection.

[0063] There are three second transmission rollers 21, and one end of the fixed belt 22 is tilted. When inserting folded cigarette paper between the fixed belt 22 and the transmission belt 12, it is more convenient.

[0064] When the lever 730 is in the unlocked position, the lever 731 is in the unlocked position, and the locking cam 732 is in the unlocked position, so that the lever 730 is unlocked and the locking cam 732 is unlocked.

[0065] After the sliding frame 7 is slid to the appropriate position, the pressure on the push block 74 is released, and the lifting rod 731 moves downward under the action of the elastic element 76, so that the clamping strip 7310 is re-engaged in the notch 410, completing the fixation between the sliding frame 7 and the mounting plate 4;

[0066] After the adjustment is completed, the motor 34 is started. The motor 34 drives the first transmission gear 51 and the seventh transmission gear 57 to rotate via the rotating shaft 311. The first transmission gear 51 meshes with the second transmission gear 52, and thus drives the first transmission gear 51, the second transmission gear 52, the third transmission gear 53, the fourth transmission gear 54 and the fifth transmission gear 55 to rotate in sequence. The third transmission gear 53 and the sixth transmission gear 56 are connected to each other via the meshing transmission between the fourth transmission gear 54 and the fifth transmission gear 55. Therefore, the third transmission gear 53 and the sixth transmission gear 56 rotate in opposite directions. The third transmission gear 53 is fixedly connected to the lower roller 310, and the sixth transmission gear 56 is fixedly connected to the upper roller 320. That is, the lower roller 310 and the upper roller 320 rotate in opposite directions.

[0067] The seventh transmission gear 57 drives the eighth transmission gear 58 to rotate through the synchronous belt 570, thereby driving the transmission belt 12 to rotate, and then the ninth transmission gear 59 and the tenth transmission gear 510 are engaged to synchronously drive the fixed belt 22 to rotate;

[0068] That is, when in use, after the motor 34 is started, the lower roller 310, the upper roller 320, the transmission belt 12 and the fixed belt 22 rotate simultaneously;

[0069] Then, a preliminarily folded cigarette paper is inserted between the fixed belt 22 and the transmission belt 12 on the right side of the transmission belt 12 (preliminary folding refers to folding the cigarette paper along the crease line so that one end of the cigarette paper is attached to the inner side of the cigarette paper without excessively squeezing the crease line). The cigarette paper moves along the fixed belt 22 and the transmission belt 12 until the folded portion of the cigarette paper enters between the lower roller 310 and the upper roller 320. The squeezing of the lower roller 310 and the upper roller 320 completes the ink burst test on the cigarette paper.

[0070] If the ink burst phenomenon does not occur in one test, the position of the upper roller 320 is readjusted by adjusting the component so that the distance between the lower roller 310 and the upper roller 320 is shortened, and the cigarette paper is subjected to a second ink burst test;

[0071] Repeat the above steps until ink bursts appear at the crease of the cigarette paper;

[0072] During the adjustment process, the fixed frame 31 and the adjustment frame 32 are hinged by the first articulated frame 530 and the second articulated frame 550, and the third transmission gear 53, the fourth transmission gear 54, the fifth transmission gear 55 and the sixth transmission gear 56 are meshed in sequence. When the adjustment frame 32 moves up and down under the action of the adjustment component, the meshing relationship between the third transmission gear 53, the fourth transmission gear 54, the fifth transmission gear 55 and the sixth transmission gear 5 does not change. That is, when the distance between the lower roller 310 and the upper roller 320 changes, the lower roller 310 and the upper roller 320 can still maintain synchronous movement with the same linear speed and opposite rotation directions.

[0073] The above describes in detail the chute-type cigarette paper ink burst testing 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.
