Technical Field
[0001] This invention relates to the field of testing device technology, specifically to an auxiliary testing device for the quality of cigarette tipping paper. Background Technology
[0002] Tipping paper, also known as cigarette tipping paper, is a type of packaging material used in cigarette manufacturing. It is specifically supplied to cigarette factories as the outer packaging for cigarette filters and is classified as a special industrial paper. Tipping paper is laser-perforated and printed with patterns and words indicating the product brand. These patterns and words are important indicators for identifying the brand and specifications of the cigarettes.
[0003] During the production and transportation of tipping paper, due to the paper's thinness and limited strength, it is prone to surface defects such as tears and holes. At the same time, the tear resistance of tipping paper directly affects the integrity of cigarette packaging and the reliability of filter connection.
[0004] In existing technologies, the quality inspection of tipping paper mainly relies on manual sampling or single-function testing equipment. Manual inspection is inefficient and highly subjective, while existing testing equipment often can only perform single-item tests and cannot simultaneously complete damage and tear resistance tests on the same device. This results in a fragmented inspection process, large equipment footprint, and low inspection efficiency. Therefore, there is a need for an auxiliary quality inspection device for cigarette tipping paper. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a quality auxiliary testing device for cigarette tipping paper. This device solves the problem that existing testing equipment can often only perform single-item testing and cannot simultaneously complete the detection of damage holes and tear resistance tests on the same equipment, resulting in a fragmented testing process, large equipment space occupation, and low testing efficiency.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A quality auxiliary detection device for cigarette tipping paper includes: The main frame has a feeding platform on its top side, which is divided into a first detection area and a second detection area from back to front. The first detection area uses a pair of detection probes to detect damage and holes in the cigarette tipping paper. The second detection area uses a second detection probe to perform a tear resistance test on the cigarette tipping paper. The tear resistance test in the second detection area is carried out by a tensioning wheel group, which intermittently tensions and pulls the cigarette tipping paper. A power shaft is rotatably connected to the bottom front end of the main frame. The power shaft is connected to a motor as a drive source through two meshing bevel gears. Guide rollers are connected to both sides of the power shaft through transmission wheel sets. The adjacent side of the guide rollers on both sides is connected to the tensioning wheel set to drive the tensioning wheel set to move. A gantry frame is fixedly connected to the top rear end of the main frame. The bottom side of the gantry frame is connected to a detection probe through a steering assembly to drive the detection probe to deflect and expand the detection range. Both sides of the steering assembly are connected to a transmission assembly through a force-applying shaft. The transmission assembly is connected to a guide roller. Synchronous shaft, with a splined shaft structure fitted at the middle end of the synchronous shaft, the synchronous shaft drives the operation of the tensioning wheel assembly through the middle end and the rear end; A translation frame slides horizontally at the front end of the gantry frame. The bottom side of the translation frame is connected to the second detection probe. The translation frame is connected to one of the force-applying shafts through a reciprocating assembly, causing the second detection probe to reciprocate and slide to detect the cigarette tipping paper on the bottom side.
[0007] Preferably, the transmission wheel assembly includes two guide wheels, with one side of each guide wheel fixedly connected to the power shaft. The guide wheels are driven by a receiving wheel through a forward guide groove and a reverse guide groove on their outer walls. The receiving wheel is rotatably connected to the main frame, and its rear end is fixedly connected to a guide roller. The forward guide groove and the reverse guide groove are alternately arranged around the outer wall of the guide wheel.
[0008] Preferably, the path lengths of the forward guide groove and the reverse guide groove are equal, so that after the guide wheel rotates one revolution, the transmission guide wheel returns to its initial position.
[0009] Preferably, the tensioning wheel assembly includes a movable frame, a fixed frame, and a lifting frame. The fixed frame is fixedly connected to the middle of the top side of the main frame. The movable frame slides horizontally to the front end of the top side of the main frame. Feeding rollers are rotatably connected inside both the movable frame and the fixed frame. Two adjacent feeding rollers are connected by two meshing steering gears. One of the steering gears is connected to the rear end of the synchronous shaft by two meshing bevel gears. The other steering gear is connected to a spline sleeve by two meshing bevel gears. The spline sleeve is fitted onto the spline shaft structure of the synchronous shaft. The lifting frame slides vertically with the main frame and is located on the side close to the movable frame and the fixed frame. A traction wheel frame is fixedly connected to the bottom side of the movable frame. An abutment roller is rotatably connected to the top side of the lifting frame. The traction wheel frame rolls against the traction groove opened at the bottom end of the lifting frame through the traction wheel at the rear end.
[0010] Preferably, guide blocks are fixedly connected to the bottom ends of both the left and right sides of the movable frame, and the guide roller slides against the guide protrusion of the guide block through the guide groove of the closed path on the outer wall.
[0011] Preferably, the steering assembly includes two traction arcs and two housings. The two traction arcs are rotatably connected to the middle of the gantry frame, and the outer wall of each traction arc has a slotted groove. The two traction arcs intersect each other, and a sliding gimbal is connected to the intersection via a slot. The bottom side of the sliding gimbal is connected to a detection probe. A quantitative steering wheel is rotatably connected to one end of each housing. The housing is fixedly connected to the gantry frame. A trigger wheel is rotatably connected to the other end of each housing. A guide protrusion is fixedly connected to one side of the trigger wheel to abut against a guide groove on the outer circumference of the quantitative steering wheel. After the quantitative steering wheel turns, it is angle-limited by a limiting buckle. The limiting buckle is rotatably connected to the inside of the housing via a torsion spring. One end of the limiting buckle abuts against the quantitative steering wheel, and the other end abuts against the outer circumference of the trigger wheel. A guide groove is provided on the outer circumference of the trigger wheel to guide the limiting buckle to deflect after the trigger wheel rotates to a specific angle.
[0012] Preferably, one side of the quantitative steering wheel is fixedly connected to an output shaft, one side of the trigger wheel is fixedly connected to an application shaft, one end of one of the output shafts is fixedly connected to the top of one of the traction arcs, and one end of the other output shaft is fixedly connected to the top of the other traction arc through two meshing bevel gears.
[0013] Preferably, the transmission assembly includes two rotating rods, which rotate on both sides of the main frame respectively. The front end of each rotating rod is fixedly connected to a guide roller, and the rear end of each rotating rod is connected to a force-applying shaft via a synchronous belt and a synchronous pulley, which engages with two meshing bevel gears.
[0014] Preferably, the reciprocating assembly includes a trigger frame that slides horizontally on one side of the gantry frame. One end of the trigger frame is connected to the translation frame via a connecting rod. The outer wall of the middle end of one of the force-applying shafts is connected to a deflection arm via two meshing gears. The other end of the trigger frame is fitted onto the end of the deflection arm via a guide groove.
[0015] Preferably, it also includes a take-up roller, which is rotatably connected to the top front end of the main frame. One side of the take-up roller is connected to the synchronous shaft through two meshing bevel gears and to the power shaft through a synchronous pulley and synchronous belt to synchronize the power. Two tensioning rollers are rotatably connected to the rear end of the main frame to form a triangular structure with the unloading roller rotating on the bottom side of the rear stage of the main frame to tension the surface of the paper being loaded.
[0016] Working principle: During feeding, the power shaft driven by the motor rotates, which in turn drives the take-up roller to rotate via the synchronous pulley and synchronous belt. This drives one end of the cigarette tipping paper that is fixed to its outer wall in advance. During the rotation of the take-up roller, the synchronous shaft is also driven to rotate via two meshing bevel gears. The rotating synchronous shaft drives the spline sleeve on the outer wall to rotate as well. The synchronous shaft and the spline sleeve are driven to rotate via two meshing bevel gears, which in turn drive the corresponding steering gears to rotate. The rotating steering gear meshes with another steering gear that meshes with it to rotate in the opposite direction. This causes the two adjacent feeding rollers connected to the steering gear to rotate synchronously. The two adjacent feeding rollers then transport the cigarette tipping paper sandwiched in the middle to the front end. During the transport process, the first detection area uses a detection probe to detect damage and holes in the cigarette tipping paper. During the feeding of cigarette tipping paper, the power shaft will also drive the guide wheel to rotate, so that the guide wheel can regularly guide the guide wheel to rotate in both directions through the arrangement of the forward and reverse guide grooves on the outer wall. The guide roller connected to the guide wheel moves the guide block through the guide groove on the outer wall, causing the guide block to move the moving frame. The spline sleeve connected to the moving frame moves along with its connected structure on the synchronous shaft and keeps rotating. The moving frame moves the traction wheel frame at its bottom along with it. The traction wheel at the rear end of the moving traction wheel frame applies force to the traction groove at the bottom of the lifting frame, causing the lifting frame to rise. Because the moving frame moves along with the feeding roller, the distance between it and the fixed frame decreases, causing the cigarette tipping paper to bulge in this area, affecting the feeding. The rising lifting frame drives the contact roller to push against the top side of the bulging area in time, causing a certain amount of traction on the bulging area of the cigarette tipping paper. The detection probe in the second detection area detects whether there is tearing to determine whether the batch of cigarette tipping paper is qualified. The rotating guide roller drives the rotating rod to rotate. The rotating rod, through two meshing bevel gears and a synchronous pulley and belt, drives the force-applying shaft to rotate. This causes the force-applying shafts on both sides to synchronously drive the trigger wheels connected to them. When the trigger wheels rotate, they pull the guide groove on the quantitative steering wheel through the guide protrusion. When the guide protrusion reaches the opening of the guide groove, the guide groove on the trigger wheel moves to the end area of the limit buckle. This causes the torsion spring on the limit buckle to reset, causing the limit buckle to deflect, thereby releasing the limit on the quantitative steering wheel and causing the quantitative steering wheel to rotate. The guide protrusion then disengages from the quantitative steering wheel. After the guide groove of the steering wheel, the guide groove disengages from the limit buckle, and the other areas of the trigger wheel apply force to the end of the limit buckle, causing it to deflect. This pulls the torsion spring, causing the limit buckle to re-limit the quantitative steering wheel. The rotating quantitative steering wheel then drives the output shaft to rotate, causing the two output shafts to drive the two traction arcs to rotate in sequence. This causes the position of the intersection of the sliding grooves on the two traction arcs to change, and the sliding gimbal to move, causing it to move the detection probe to another position for detection. The gimbal structure on the sliding gimbal will keep the detection camera of the traction arc pointing downwards to expand the detection range. One of the rotating force-applying shafts will drive the deflection arm through two meshing gears, causing the deflection arm to pull the trigger frame, making the trigger frame reciprocate and move through the linkage to push and pull the translation frame, so that the detection probes on the bottom side of the translation frame can detect different areas of the traction part of the cigarette tipping paper.
[0017] This invention provides an auxiliary device for quality inspection of cigarette tipping paper. It has the following beneficial effects: 1. This invention uses the same power transmission system for two detection areas, eliminating the need for an additional independent drive device. This effectively reduces the equipment footprint and manufacturing costs. It also avoids the transfer of the spliced paper between different detection devices, reducing the risk of secondary contamination and additional damage, and significantly improving detection efficiency and ease of operation.
[0018] 2. This invention, through intermittent transmission in conjunction with the tensioning wheel assembly, can intermittently tension and pull the cigarette tipping paper, simulating the stress state during actual use. This makes the tear resistance test closer to real working conditions, improving the accuracy and reliability of the test results, while avoiding excessive paper damage caused by continuous pulling.
[0019] 3. This invention utilizes the cooperation of the limiting buckle and the guide groove to trigger the deflection of the traction arc at a specific angle, thereby moving the sliding gimbal and the detection probe to different detection positions. The gimbal structure on the sliding gimbal ensures that the detection camera continues to face downwards, effectively expanding the detection coverage of a single probe, reducing detection blind spots, and improving the comprehensiveness and accuracy of damage and hole detection.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Example: This invention provides an auxiliary quality testing device for cigarette tipping paper, comprising: Please see the appendix Figure 1 -Appendix Figure 3The main frame 1 has a feeding platform on its top side, which is divided into a first inspection area and a second inspection area from back to front. The first inspection area uses inspection probe 16 to detect damage and holes in the cigarette tipping paper. The second inspection area uses inspection probe 24 to perform a tear resistance test on the cigarette tipping paper. The tear resistance test in the second inspection area is carried out by a tensioning wheel group, which intermittently tensions and pulls the cigarette tipping paper. Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 11 It also includes a take-up roller 30, which is rotatably connected to the top of the front end of the main frame 1. One side of the take-up roller 30 is connected to the synchronous shaft 28 through two meshing bevel gears and to the power shaft 2 through a synchronous pulley and synchronous belt to synchronize the power. Two tension rollers 32 are rotatably connected to the rear end of the main frame 1 to form a triangular structure with the feed roller 31 rotating on the bottom side of the rear stage of the main frame 1 to tension the surface of the paper being loaded. Specifically, during feeding, the power shaft 2 driven by the motor rotates, causing the take-up roller 30 to rotate via a synchronous pulley and synchronous belt. This pulls one end of the cigarette tipping paper, which is pre-fixed on its outer wall. During the rotation of the take-up roller 30, the synchronous shaft 28 is also driven to rotate via two meshing bevel gears. The rotating synchronous shaft 28 drives the spline sleeve 29 on the outer wall to rotate as well. The synchronous shaft 28 and the spline sleeve 29 are driven to rotate via two meshing bevel gears, which in turn drive the corresponding steering gear 7 to rotate. The rotating steering gear 7 meshes with another steering gear 7 that meshes with it to rotate in the opposite direction. This causes the two adjacent feeding rollers 6 connected to the steering gear 7 to rotate synchronously, so that the two adjacent feeding rollers 6 convey the cigarette tipping paper sandwiched in the middle to the front end. During the conveying process, the first detection area uses the detection probe 16 to detect damage and holes in the cigarette tipping paper.
[0024] Please see the appendix Figure 4 -Appendix Figure 6A power shaft 2 is rotatably connected to the bottom front end of the main frame 1. The power shaft 2 is connected to a motor, which serves as the drive source, via two meshing bevel gears. Guide rollers 10 are connected to both sides of the power shaft 2 via transmission wheel sets. The adjacent sides of the guide rollers 10 are connected to a tensioning wheel set to drive the tensioning wheel set. The transmission wheel set includes two guide wheels 8, with adjacent sides of the two guide wheels 8 fixedly connected to the power shaft 2. The guide wheels 8 transmit power to a guide wheel 9 through forward and reverse guide grooves on their outer walls. The guide wheel 9 is rotatably connected to the main frame 1, and its rear end is fixedly connected to the guide rollers 10. Forward and reverse guide grooves alternately surround the outer wall of the guide wheel 8, with varying numbers of alternations, but the path lengths of the forward and reverse guide grooves are equal. After one rotation of the guide wheel 8, the guide wheel 9 returns to its initial position. Position, making random variables controllable, forming a regular quantitative structure. The tensioning wheel assembly includes a movable frame 3, a fixed frame 5, and a lifting frame 21. The fixed frame 5 is fixedly connected to the middle of the top side of the main frame 1. The movable frame 3 slides horizontally at the front end of the top side of the main frame 1. Feeding rollers 6 are rotatably connected inside both the movable frame 3 and the fixed frame 5. Two adjacent feeding rollers 6 are connected by two meshing steering gears 7. The lifting frame 21 slides vertically with the main frame 1 and is located on the side close to the movable frame 3 and the fixed frame 5. A traction wheel frame 23 is fixedly connected to the bottom side of the movable frame 3. An abutment roller 22 is rotatably connected to the top side of the lifting frame 21. The traction wheel frame 23 rolls and abuts against the traction groove opened at the bottom end of the lifting frame 21 through the traction wheel at the rear end. Guide blocks 11 are fixedly connected to the bottom ends of both the left and right sides of the movable frame 3. The guide roller 10 slides and abuts against the guide protrusion of the guide block 11 through the guide groove of the closed path on the outer wall. Specifically, during the cigarette tipping paper conveying process, the power shaft 2 also rotates the drive guide wheel 8, causing the guide wheel 8 to regularly guide the receiving wheel 9 to rotate in both directions through the arrangement of the forward and reverse guide grooves on the outer wall. The guide roller 10 connected to the receiving wheel 9 drives the guide block 11 to move through the guide groove on the outer wall, causing the guide block 11 to drive the moving frame 3 to move. This causes the spline sleeve 29 connected to the moving frame 3, along with its connected structure, to move on the synchronous shaft 28 and maintain rotation. The moving frame 3, in turn, drives the traction wheel frame 23 at its bottom to move along with it. The displacement of the traction wheel frame 23 causes the rear traction wheel to exert force on the traction groove at the bottom of the lifting frame 21, causing the lifting frame 21 to rise. As the moving frame 3 and the feeding roller 6 are displaced together, the distance between them and the fixed frame 5 decreases, causing the conveyed cigarette tipping paper to bulge in this area, affecting the feeding. The rising lifting frame 21 drives the contact roller 22 to push against the top side of the bulging area in time, causing a certain amount of traction on the bulging area of the cigarette tipping paper. The detection probe 24 in the second detection area detects whether there is tearing, and judges whether the batch of cigarette tipping paper is qualified.
[0025] Please see the appendix Figure 7 Appendix Figure 9 and attached Figure 10 The gantry frame 4 is fixedly connected to the top rear end of the main frame 1. The bottom side of the gantry frame 4 is connected to the detection probe 16 via a steering assembly to drive the detection probe 16 to deflect and expand the detection range. Both sides of the steering assembly are connected to transmission components via force-applying shafts 13. The transmission components are connected to guide rollers 10. The steering assembly includes two traction arcs 15 and two housings 17. The two traction arcs 15 are rotatably connected to the middle of the gantry frame 4, and the outer wall of the traction arcs 15 has a slotted groove. The arcs 15 intersect each other, and a sliding gimbal 33 is connected to the intersection via a groove. The bottom side of the sliding gimbal 33 is connected to the detection probe 16. A quantitative steering wheel 18 is rotatably connected to one end of the housing 17. The housing 17 is fixedly connected to the gantry 4. A trigger wheel 19 is rotatably connected to the other end of the housing 17. A guide protrusion is fixedly connected to one side of the trigger wheel 19 to abut against the guide groove on the outer circumference of the quantitative steering wheel 18. After the quantitative steering wheel 18 turns, it is angle-limited by the limit buckle 20. The limiting buckle 20 is rotatably connected to the inside of the housing 17 via a torsion spring. In its normal state, it limits the metering guide wheel 18, and the torsion spring is in a compressed state. One end of the limiting buckle 20 abuts against the metering guide wheel 18, and the other end abuts against the outer periphery of the trigger wheel 19. A guide groove is provided on the outer periphery of the trigger wheel 19 to guide the limiting buckle 20 to deflect after the trigger wheel 19 rotates to a specific angle. A force-output shaft 14 is fixedly connected to one side of the metering guide wheel 18, and a force-applying shaft 14 is fixed to one side of the trigger wheel 19. Shaft 13 is fixedly connected. One end of one output shaft 14 is fixedly connected to the top end of one traction arc 15. One end of the other output shaft 14 is fixedly connected to the top end of another traction arc 15 through two meshing bevel gears. The transmission assembly includes two rotating rods 12. The two rotating rods 12 rotate on both sides of the main frame 1 respectively. The front end of the rotating rod 12 is fixedly connected to the guide roller 10. The rear end of the rotating rod 12 is connected to the force-applying shaft 13 through a synchronous belt and synchronous pulley in cooperation with two meshing bevel gears. Specifically, the rotating guide roller 10 drives the rotating rod 12 to rotate. The rotating rod 12 drives the force-applying shaft 13 to rotate through two meshing bevel gears and a synchronous belt. This causes the force-applying shafts 13 on both sides to synchronously drive the trigger wheel 19 connected to them. When the trigger wheel 19 rotates, it pulls the guide groove on the quantitative steering wheel 18 through the guide protrusion. When the guide protrusion reaches the opening of the guide groove, the guide groove on the trigger wheel 19 moves to the end area of the limit buckle 20. This causes the torsion spring on the limit buckle 20 to reset, causing the limit buckle 20 to deflect, thereby releasing the limit on the quantitative steering wheel 18 and causing the quantitative steering wheel 18 to rotate. The limit wheel 18 then rotates as the guide protrusion disengages from the limit. After the guide groove of the quantitative steering wheel 18 is disengaged, the guide groove disengages from the limit buckle 20, and the other areas of the trigger wheel 19 apply force to the end of the limit buckle 20, causing it to deflect and pull the torsion spring, so that the limit buckle 20 re-limits the quantitative steering wheel 18. The rotating quantitative steering wheel 18 drives the output shaft 14 to rotate, so that the two output shafts 14 drive the two traction arcs 15 to rotate in sequence, so that the position of the intersection of the sliding grooves on the two traction arcs 15 changes, and the sliding gimbal 33 is displaced, so that it drives the detection probe 16 to move to another position for detection. The gimbal structure on the sliding gimbal 33 will keep the detection camera of the traction arc 15 pointing downward to expand the detection range.
[0026] Synchronous shaft 28, with a splined shaft structure fitted at the middle end of synchronous shaft 28. Synchronous shaft 28 drives the operation of tensioning wheel assembly through the middle end and the rear end. One of the steering gears 7 is connected to the rear end of synchronous shaft 28 through two meshing bevel gears. The other steering gear 7 is connected to a splined sleeve 29 through two meshing bevel gears. The splined sleeve 29 is fitted on the splined shaft structure of synchronous shaft 28. Please see the appendix Figure 7 and attached Figure 8 The translation frame 25 slides horizontally at the front end of the gantry frame 4. The bottom side of the translation frame 25 is connected to the second detection probe 24. The translation frame 25 is connected to one of the force-applying shafts 13 through a reciprocating assembly, causing the second detection probe 24 to reciprocate and slide to detect the cigarette tipping paper on the bottom side. The reciprocating assembly includes a trigger frame 26, which slides horizontally on one side of the gantry frame 4. One end of the trigger frame 26 is connected to the translation frame 25 through a connecting rod. The outer wall of the middle end of one of the force-applying shafts 13 is connected to a deflection arm 27 through two meshing gears. The other end of the trigger frame 26 is sleeved on the end of the deflection arm 27 through a guide groove. Specifically, one of the rotating force-applying shafts 13 will drive the deflection arm 27 through two meshing gears, causing the deflection arm 27 to pull the trigger frame 26, causing the trigger frame 26 to reciprocate and move through the connecting rod to push and pull the translation frame 25 for displacement, so that the detection probe 24 on the bottom side of the translation frame 25 can detect different areas of the traction part of the cigarette tipping paper.
