Description

Technical Field

[0001] The invention relates to the technical field of friction discoloration resistance test, in particular to a packaging box ink printing friction discoloration resistance test device based on a physical sensor. Background Art

[0002] In the packaging and printing industry, the ink printing quality of packaging boxes is of vital importance. The traditional packaging box ink printing friction and discoloration resistance test device has many limitations. The existing detection methods generally ignore the influence of physical pressure factors on the wear resistance of ink. The combined effect of pressure and friction will significantly affect the adhesion and wear resistance of ink. However, the linear friction test is adopted, and the pressure sensor is directly used to perform pressure detection. Although this method is relatively simple to operate, it has many limitations. On the one hand, the linear friction method is very different from the stress conditions of the packaging box in the actual use scenario. During transportation, the packaging box will be subjected to friction from all directions due to handling, stacking, and collision with other objects. It is difficult for linear friction to simulate this complex stress state, resulting in deviations in the evaluation of the wear resistance of ink, and it is unable to accurately reflect the durability of ink in real environment. , it is impossible to accurately detect the friction resistance of ink under different pressure conditions. At this time, it is necessary to set up a high-precision pressure sensor in the test device and use it together to make the test results closer to actual usage. At the same time, since the surface of the packaging box may be uneven and the ink coating may be uneven, a single friction method is likely to cause local test result deviations and cannot truly reflect the overall wear resistance of the ink. In addition, during the test, there is a lack of effective cleaning and collection methods for the ink debris and impurities generated by friction. These impurities will interfere with the observation of ink wear and affect the accuracy of the test results. Moreover, existing devices can usually only provide a fixed friction pressure and cannot simulate the pressure changes that the packaging box is subjected to in different environments. It is difficult to obtain the wear resistance data of the ink under different pressure conditions. For this reason, we propose a packaging box ink printing friction decolorization resistance test device based on physical sensors. Summary of the invention

[0014] Compared with the prior art, the advantages and positive effects of the present invention are 1.

[0015] 2. The present invention proposes a packaging box ink printing friction and discoloration resistance test device based on physical sensors, which can drive the bottom spur gear to rotate by rotating the rotating rod clockwise, and the spur gear drives the gear ring to move and deflect at the same time, so that the grinding wheel can rotate while moving along the inside of the limiting groove as a whole. The rotation of the grinding wheel can make different parts of its surface contact with the packaging box ink in turn, and the movement along the limiting groove can ensure friction testing at different positions. The combination of the two can make all areas of the ink surface subject to friction, and rub the ink at different positions and angles, thereby reducing the deviation of local test results caused by factors such as uneven surface of the packaging box and uneven ink coating, so that the test results can better reflect the true wear resistance of the ink and reduce the influence of individual differences on the test results.

[0016] 3. The present invention proposes a packaging box ink printing friction and decolorization resistance test device based on physical sensors, which drives the support rod to rotate through the rotation of the bevel gear, and the rotation of the first rotating plate drives the first mounting rod to slide back and forth inside the mounting groove through the second rotating plate, thereby driving the cleaning brush and the exhaust fan to move back and forth relative to each other through the fixed frame. The cleaning brush can move back and forth to clean the toner rubbed off the surface, and collect the toner through the exhaust fan, effectively brushing off the ink debris, wear particles and other impurities remaining on the surface of the packaging box after the friction test, so that the surface of the packaging box is restored to a relatively clean state, and the wear marks and scratches of the ink are more clearly displayed, which is convenient for observing the wear of the ink and avoiding the interference of impurities in the judgment of the test results.

[0017] 4. The present invention proposes a packaging box ink printing friction discoloration resistance test device based on physical sensors. During the friction process, the air pump is started. The air pump allows the air flow to enter the interior of the friction wheel from the through hole and pumps it under the partition to squeeze the friction wheel, making its bottom larger, thereby applying greater pressure to the packaging box and thus greater friction, thereby adjusting the friction force on the packaging box. The friction wheel pressure is adjusted by the air pump, and the second pressure sensor arranged inside can detect the air pressure inside the friction wheel, making the data more accurate and better simulating the friction conditions under different pressure conditions that the packaging box is subjected to during transportation, storage and use, so that the test results are closer to the actual application scenarios, and the wear resistance of the ink in the actual environment can be more accurately evaluated. At the same time, the wear resistance data of the ink under different pressures can be obtained according to the test requirements. BRIEF DESCRIPTION OF THE DRAWINGS

The outer surface of the rotating disk 5 is provided with teeth 13, and at the same time meshes with the rack 14 on the limiting slide rail 3. When the rotating disk 5 moves along the direction of the electric slide rail 2, the rotating disk 5 can be driven to rotate through the cooperation of the teeth 13 and the rack 14. Since the rotating disk 5 is in the shape of a Leno triangle, the moving trajectory of the center point of the rotating disk 5 is wavy, and the rotating disk 5 can rotate while moving, so as to facilitate the friction of the packaging box in different directions. The first pressure sensor 44 set can conveniently record the friction resistance of the ink on the surface of the cardboard under different pressure conditions under the condition of curved friction.

[0024] like Figure 1 - Fig. 9As shown, the outer surface of the rotating disk 5 is fixedly connected with a plurality of teeth 13, the inner surface of the limiting slide rail 3 is fixedly connected with a rack 14, the rack 14 is meshed with the teeth 13, the inner surface of the limiting groove 10 is provided with a plurality of slots 15, the inner surfaces of the plurality of slots 15 are rotatably connected with a card plate 16 through a bearing, a spring 17 is fixedly connected between the plurality of card plates 16 and the slots 15, the outer surface of the connecting rod 11 is fixedly connected with a sliding card block 18, the sliding card block 18 is slidably connected with the limiting groove 10, the lower surface of the positioning rod 6 is fixedly connected with a first bevel gear 19, the inner surface of the first bevel gear 19 is rotatably connected with a rotating rod 20 The outer surface of the rotating rod 20 is fixedly connected to the second bevel gear 21, the upper surface of the movable plate 9 is fixedly connected to the support plate 22, the outer surface of the support plate 22 is rotatably connected to the support rod 23 through a bearing, the outer surface of the support rod 23 is fixedly connected to the third bevel gear 24, the third bevel gear 24 is meshed with the first bevel gear 19 and the second bevel gear 21 respectively, the rotating rod 20 is rotatably connected to the movable plate 9, the lower surface of the rotating rod 20 is fixedly connected to the spur gear 25, the outer surface of the connecting rod 11 is fixedly connected to the connecting plate 26, the outer surface of the connecting plate 26 is fixedly connected to the gear ring 27, and the gear ring 27 is meshed with the spur gear 25.

[0025] The effect is that when the rotating disk 5 drives the positioning rod 6 to rotate, the positioning rod 6 drives the first bevel gear 19 at the bottom to rotate, and a double ratchet pawl structure is provided between the first bevel gear 19 and the rotating rod 20 rotating inside, and a double ratchet pawl structure is also provided between the second bevel gear 21 and the rotating rod 20. When the first bevel gear 19 rotates clockwise, the rotating rod 20 is driven to rotate clockwise through the double ratchet pawls, and at this time, the rotating rod 20 cannot drive the second bevel gear 21 to rotate; when the first bevel gear 19 rotates counterclockwise, at this time, due to the structure of the double ratchet pawls, the rotating rod 20 will not be driven to rotate, the first bevel gear 19 drives the third bevel gear 24 to rotate, the third bevel gear 24 drives the second bevel gear 21 to rotate, and the second bevel gear 21 can drive the rotating rod 20 to rotate clockwise through the double ratchet pawls provided inside. For this reason, when the positioning rod 6 rotates clockwise or counterclockwise, the rotating rod 20 will rotate clockwise, and the rotating rod 2 rotating clockwise 0 can drive the spur gear 25 at the bottom to rotate, and the sliding block 18 arranged on the outer surface of the connecting rod 11 always slides inside the limiting groove 10. When the spur gear 25 contacts the gear ring 27, the spur gear 25 drives the gear ring 27 to move and deflect at the same time, and a card slot 15 is arranged inside the limiting groove 10, and a card plate 16 is arranged inside the card slot 15, so that when the connecting rod 11 passes the position of the card plate 16, the spring 17 will be squeezed and moved to the other side of the card plate 16, and then the card plate 16 will be restored by the elastic force of the spring 17. At this time, the connecting rod 11 continues to be stressed and will be blocked by the card plate 16. In this way, when each connecting rod 11 passes the end point and the side line of the triangle close to the middle position, it will not retreat, and will move clockwise along the limiting groove 10, and drive the friction wheel 12 at the bottom to move. The friction wheel 12 contacts the packaging box, and the friction fading resistance test can be performed on the surface of the packaging box printed with ink.

[0026] like Figure 1 - Fig. 9As shown, a partition plate 28 is fixedly connected to the inner surface of the friction wheel 12, a pump body 29 is installed on the surface of the partition plate 28, a through hole 30 is opened on the upper surface of the friction wheel 12, a second pressure sensor 45 is installed on the inner surface of the friction wheel 12, a first rotating plate 31 is fixedly connected to the outer surface of the support rod 23, the outer surface of the first rotating plate 31 is rotatably connected to the second rotating plate 32 through a bearing, one end of the second rotating plate 32 is rotatably connected to the first mounting rod 33 through a bearing, the outer surface of the support rod 23 is rotatably connected to the fixed plate 34 through a bearing, the outer surface of the fixed plate 34 is rotatably connected to the second mounting rod 35 through a bearing, the first mounting rod 33 and the second mounting rod 35 are rotatably connected to the first mounting rod 33 and the second mounting rod 35. The outer surface of the rod 35 is fixedly connected to a fixing frame 36, wherein an exhaust fan 37 is installed on the lower surface of one of the fixing frames 36, and a cleaning brush 38 is installed on the lower surface of the other fixing frame 36. The outer surface of the sliding seat 4 is fixedly connected to a mounting plate 39, and a mounting groove 40 is provided on the outer surface of the mounting plate 39. The first mounting rod 33 and the second mounting rod 35 are both slidably connected to the mounting groove 40. The upper surface of the sliding seat 4 is slidably connected to a sliding frame 41, and the sliding frame 41 is rotatably connected to the positioning rod 6 through a bearing. The outer surface of the sliding frame 41 is fixedly connected to a vertical rod 42, and the vertical rod 42 is rotatably connected to the positioning rod 6. A video recorder 43 is installed on the lower surface of the vertical rod 42.

[0027] The effect is that during the repeated friction process, the video recorder 43 arranged at the bottom of the vertical rod 42 can record the friction conditions of the packaging box in real time. When the bevel gear rotates to drive the support rod 23 to rotate, the first rotating plate 31 can be driven to rotate, and the other end of the first rotating plate 31 drives one end of the second rotating plate 32 to rotate. The other end of the second rotating plate 32 is provided with a first mounting rod 33, and the first mounting rod 33 slides in the mounting groove 40, which can drive the first mounting rod 33 to slide back and forth inside the mounting groove 40. At the same time, the movable plate 9 is limited by the limiting frame 8 and can slide back and forth on the limiting frame 8. The support rod 23 follows the movable plate 9 to reciprocate. At this time, the support rod 23 can drive the fixed plate 34 to move, and the fixed plate 34 drives the second end The second mounting rod 35 moves, and a fixing frame 36 is provided at the bottom of the first mounting rod 33 and the second mounting rod 35. The cleaning brush 38 at the bottom of the fixing frame 36 moves back and forth to clean the toner rubbed off the surface, and the toner is collected by the exhaust fan 37. At the same time, during the friction process, the air pump can be started, and the air pump draws air above the partition 28 into the bottom, and the air flow enters the friction wheel 12 from the through hole 30. The bottom of the friction wheel 12 is a soft material. When the air flow is pumped in, it will squeeze the friction wheel 12 to expand its bottom. The second pressure sensor 45 arranged inside can detect the air pressure inside the friction wheel 12, so that the data is more accurate. At the same time, the pressure applied to the packaging box is greater, which makes the friction greater, thereby adjusting the friction force on the packaging box.

[0028] Working principle: place the packaging box on the conveyor belt 46 and fix its position by an external fixer. At this time, by starting the electric slide rail 2, the electric slide rail 2 drives the sliding seat 4 to move. The positioning groove 7 provided on the surface of the sliding seat 4 can push the positioning rod 6 to move. The positioning rod 6 drives the rotating disk 5 to move along the direction of the electric slide rail 2. The outer surface of the rotating disk 5 is provided with teeth 13, and at the same time, it meshes with the rack 14 on the limiting slide rail 3. When the rotating disk 5 moves along the direction of the electric slide rail 2, the cooperation of the teeth 13 and the rack 14 can drive the rotating disk 5 to rotate. Since the rotating disk 5 is in the shape of a Leno triangle, the moving trajectory of the center point of the rotating disk 5 is wavy, and the rotating disk 5 can rotate while moving, so as to facilitate the unfixed positioning of the packaging box. Friction in the same direction, when the rotating disk 5 drives the positioning rod 6 to rotate, the positioning rod 6 drives the first bevel gear 19 at the bottom to rotate, and a double ratchet pawl structure is provided between the first bevel gear 19 and the rotating rod 20 rotating internally, and a double ratchet pawl structure is also provided between the second bevel gear 21 and the rotating rod 20. When the first bevel gear 19 rotates clockwise, the rotating rod 20 is driven to rotate clockwise through the double ratchet pawls. At this time, the rotating rod 20 cannot drive the second bevel gear 21 to rotate. When the first bevel gear 19 rotates counterclockwise, at this time, the structure of the double ratchet pawls will not drive the rotating rod 20 to rotate, the first bevel gear 19 drives the third bevel gear 24 to rotate, and the third bevel gear 24 drives the second bevel gear 21 to rotate, and the second bevel gear 21 can be driven by the double ratchet pawls provided internally To drive the rotating rod 20 to rotate clockwise, when the positioning rod 6 rotates clockwise or counterclockwise, the rotating rod 20 will rotate clockwise, and the clockwise rotating rotating rod 20 can drive the spur gear 25 at the bottom to rotate. The sliding block 18 arranged on the outer surface of the connecting rod 11 always slides inside the limiting groove 10. When the spur gear 25 contacts the gear ring 27, the spur gear 25 drives the gear ring 27 to move and deflects at the same time, and a card slot 15 is arranged inside the limiting groove 10, and a card plate 16 is rotatably arranged inside the card slot 15, so that when the connecting rod 11 passes the position of the card plate 16, the spring 17 will be squeezed and moved to the other side of the card plate 16, and then the card plate 16 will be restored by the elastic force of the spring 17. At this time, the connecting rod 11 continues to be stressed and will be clamped by the card plate 1 6 is used to block, and when the connecting rod 11 approaches the end point of the limiting groove 10, it squeezes the front end of the card plate 16. At this time, the card plate 16 will rotate around the bearing, and the tail end of the card plate 16 will tilt up. At this time, the tail end will block the connecting rod 11 near the middle position of the edge line. In this way, when each connecting rod 11 passes through the end point of the triangle and the position near the middle of the edge line, it will not retreat, and will move clockwise along the limiting groove 10, and drive the friction wheel 12 at the bottom to move. The friction wheel 12 contacts the packaging box, and the friction and discoloration resistance test of the packaging box surface printed with ink can be carried out. At the same time, during the repeated friction process, the video recorder 43 set at the bottom of the vertical rod 42 can record the friction condition of the packaging box in real time. When the bevel gear rotates to drive the support rod 23 to rotate,The first rotating plate 31 can be driven to rotate, and the other end of the first rotating plate 31 drives one end of the second rotating plate 32 to rotate. The other end of the second rotating plate 32 is provided with a first mounting rod 33, and the first mounting rod 33 slides in the mounting groove 40, so that the first mounting rod 33 can be driven to slide back and forth inside the mounting groove 40. At the same time, the movable plate 9 is limited by the limiting frame 8 and can slide back and forth on the limiting frame 8. The support rod 23 follows the movable plate 9 to move back and forth. At this time, the support rod 23 can drive the fixed plate 34 to move, and the fixed plate 34 drives the second mounting rod 35 at the other end to move. The bottom of the first mounting rod 33 and the second mounting rod 35 is provided with a fixing frame 36, and a cleaning brush at the bottom of the fixing frame 36 The back and forth movement of 38 can clean the toner rubbed off the surface, and the toner can be collected by the exhaust fan 37. At the same time, during the friction process, the air pump can be started to draw air from the top of the partition 28 into the bottom, and the airflow enters the friction wheel 12 from the through hole 30. The bottom of the friction wheel 12 is a soft material. When the airflow is pumped in, it will squeeze the friction wheel 12 to expand its bottom. At the same time, the pressure applied to the packaging box is greater, making the friction greater, thereby adjusting the friction force on the packaging box. The ink condition on the surface of the packaging box is recorded in real time by the video recorder 43, and the wear resistance of the ink on the surface of the packaging box is achieved by observing the recorded video or directly observing the wear resistance of the ink on the surface of the packaging box.
