Description

Technical Field

[0001] The present invention relates to the technical field of adhesive measurement, and in particular to a device for measuring the adhesive force of a paper cigarette material and a method for using the device. Background Art

[0002] Cigarette adhesives have achieved remarkable results in the cigarette packaging industry due to their environmental friendliness and fast curing speed. At the same time, the application areas of cigarette packaging materials are constantly expanding, especially paper cigarette packaging materials (tipping paper, cigarette box sheets, seals, etc.) that have been processed by coating, etc., and their surfaces are mostly post-processed with UV varnish, UV ink, double-sided lamination and coatings with extremely low surface energy, which poses new challenges to the bonding performance of adhesives.

[0003] The widespread application of new materials, new technologies and new equipment in tobacco materials has led to changes in their surface properties to meet the needs of new products. At the same time, it has also caused problems with the adaptability of tobacco packaging materials and adhesives to the machine, resulting in the instability of the quality of finished cigarette products. At present, Hubei China Tobacco is focusing on expanding the application field and scope of transfer-type tipping paper. However, compared with ordinary tipping paper, since transfer-type tipping paper is further processed on its finished paper surface, a new interface is formed by coating and printing chemicals, and its interface has certain hydrophobicity and impermeability, resulting in certain defects in the adaptability of the machine during the cigarette making process, which has a certain impact on the production efficiency of the tobacco factory. Previous studies have shown that the adaptability of tipping paper to the machine is highly correlated with the type of paper. Ordinary paper performs better than transfer tipping paper in quality issues such as glue absorption, adhesion, and curling; paper water absorption and contact angle are highly correlated with the efficiency and quality of tipping paper on the machine. Due to the rapid curing nature of adhesives, the contact angle θ measurement is inaccurate. The above tests all have certain limitations and cannot truly reflect the situation of tipping paper on the machine. In addition, the adhesive force of the overlapping position of the tipping paper has a direct impact on the production process and the winding quality of the final product.

[0004] As a result, different people use the same experimental method to test the adhesion of tobacco materials. The numerical values ​​vary greatly. The major influencing factors are the insufficient accuracy of adhesive dispensing and the lack of repeatability in the measurement process. When dispensing, it is difficult to locate the dispensing position. If the adhesive cannot be dispensed to the center of the glue table, the adhesion test will vary greatly. The amount of dispensing is difficult to control. The difference in the amount of dispensing will directly affect the accuracy of the adhesion test. It is difficult to quickly transport the adhesive on the glue table to the adhesion test area after dispensing, resulting in changes in the properties of the adhesive and a decrease in the accuracy of the adhesion test. When measuring, there is a problem with the measurement angle. The bottom surface of the measuring head is not close to the load-bearing The upper surface of the adhesive placement table cannot be guaranteed to be parallel, resulting in changes in the measuring angle during the adhesion measurement, and a decrease in the measurement accuracy; there is a problem with the measurement position. When the bottom surface of the measuring head descends to contact the upper surface of the adhesive placement table, a collision is inevitable. In the least, the position of the measuring head or the adhesive placement table will change, resulting in a deviation in the measurement position; in the worst case, the measuring head or the adhesive placement table will be damaged; the measurement period cannot be determined. The adhesion includes initial adhesion (initial adhesion) and continuous adhesion (maintaining adhesion). The current adhesion measurement still relies on the operator to twist the adhesive by hand multiple times, and the accurate measurement time of the adhesive cannot be obtained, and the measurement accuracy is insufficient.

[0005] Therefore, in order to solve the above problems, it is very necessary for us to design a reasonable and efficient device and method for measuring the adhesion of paper cigarette materials. Summary of the invention

For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted or combined. In addition, features described in some examples may be combined in other examples.

[0022] Example 1: Please refer to Figures 1 to 3 , which is only one embodiment of the present invention, a paper cigarette material adhesion measurement device, including a glue injection part 1, a glue placement table 2 and a measurement part 5; the lower side of the glue placement table 2 is arranged on a horizontal slide rail 4 through a glue placement seat 22; one end of the horizontal slide rail 4 is arranged on the lower side of the glue injection part 1, and the other end of the horizontal slide rail 4 is arranged on the lower side of the measurement part 5; the glue injection part 1 includes a glue injection cylinder 11 and a functional probe 12, a glue placement plate 21 is arranged on the glue placement table 2, and the measurement part 5 includes a measurement table 51, a vertical slide frame 52 for facilitating the sliding of the measurement table 51, an extension column 53 arranged on the lower side of the measurement table 51, and a measurement head 54 arranged at the lower end of the extension column 53, and a sensor for obtaining the tension at the lower end of the measurement head 54 is arranged in the measurement table 51.

[0023] In the present invention, the glue placing platform 2 can be horizontally displaced along the horizontal slide rail 4, one end of the horizontal slide rail 4 is arranged at the lower side of the glue injection part 1, and the other end of the horizontal slide rail 4 is arranged at the lower side of the measuring part 5; when the glue placing platform 2 is horizontally displaced along the horizontal slide rail 4 to one end close to the glue injection part 1, the glue injection part 1 dispenses the adhesive onto the glue placing platform 2; when the glue placing platform 2 is horizontally displaced along the horizontal slide rail 4 to one end close to the measuring part 5, the measuring part 5 measures the adhesion force of the adhesive on the glue placing platform 2.

[0024] First, the structure of the glue placing table 2, a glue placing plate 21 is arranged on the glue placing table 2, the lower side of the glue placing table 2 is arranged on the horizontal slide rail 4 through the glue placing seat 22, at least a part of the horizontal slide rail 4 is arranged on the lower side of the measuring part 5, the glue placing seat 22 on the lower side of the glue placing table 2 slides on the horizontal slide rail 4, in fact, the glue placing table 2 slides to the glue dispensing position, the specified adhesive is dispensed on the glue placing plate 21, and then the glue placing table 2 slides along the horizontal slide rail 4 to the lower side of the measuring part 5, at this time, it is convenient for the measuring part 5 to measure the adhesion of the adhesive on the glue placing plate 21.

[0025] Next is the structure of the glue injection part 1, which includes a glue injection cylinder 11 and a functional probe 12. The glue injection part 1 is arranged on the vertical slide rail 3 through a sliding vertical plate 13, that is, the glue injection cylinder 11 and the functional probe 12 are both arranged on the sliding vertical plate 13. The sliding vertical plate 13 means that it is vertically arranged and can slide along the vertical slide rail 3 after being used to support the glue injection cylinder 11 and the functional probe 12; the extension directions of the glue injection cylinder 11 and the functional probe 12 are parallel to the sliding vertical plate 13, that is, the glue injection cylinder 11 and the functional probe 12 are both vertically arranged; the functional probe 12 is extended downward, and after observing the center position of the glue placement platform 2, the adhesive at the glue injection cylinder 11 can be dispensed to the center position of the glue placement platform 2.

[0026] Furthermore, the functional probe 12 can also obtain the volume and shape of the adhesive dispensed onto the adhesive placement table 2, so as to further calculate the dispensed amount.

[0027] Next, the structure of the measuring part 5 includes a measuring table 51, a vertical slide frame 52 for facilitating the sliding of the measuring table 51, an extension column 53 arranged on the lower side of the measuring table 51, and a measuring head 54 arranged at the lower end of the extension column 53. That is to say, the measuring table 51 can slide up and down along the vertical slide frame 52, that is, it can be lifted and lowered. An extension column 53 extends from the lower side of the measuring table 51, and a measuring head 54 is installed at the lower end of the extension column 53. When the measuring table 54 descends, the measuring head 54 extends downward to the glue plate 21 and contacts with the adhesive. The measuring table 54 ascends again. At this time, the measuring head 54 overcomes the adhesive force of the adhesive until the moment the measuring head 54 is separated from the glue plate 21. The force applied to the measuring head 54 is the adhesive force of the adhesive.

[0028] Therefore, a sensor for obtaining the tension at the lower end of the measuring head 54 is provided in the measuring platform 51 .

[0029] When the measuring head 54 is unloaded, the reading of the sensor is reset to zero, and then when the measuring head 54 moves downward to contact the adhesive plate 21, the sensor reading is negative, which is the squeezing force of the measuring head 54 on the adhesive plate 21. Controlling this force can facilitate the full adhesion of the adhesive. Then the measuring head 54 moves up and down until it is separated from the adhesive plate 21. The sensor reading is positive, and the maximum reading is the bonding strength of the adhesive.

[0030] It should be noted that: the adhesive plate 21 is provided with test paper, and the adhesive is actually dispensed on the test paper. When the adhesive strength is measured, the adhesive strength of the adhesive is also measured between the measuring head and the test paper. The test paper is fixed on the adhesive plate 21. For example, a clipboard is provided around the adhesive plate 21 to fix the test paper. After each test, the test paper needs to be replaced, and the adhesive is dispensed and measured again. Furthermore, if it is necessary to test the adhesion strength of the specified adhesive between the first specified material paper and the second specified material paper, the first specified material paper can be set on the adhesive plate 21, and the second specified material paper can be clamped and fixed on the lower side of the measuring head 54, and then the predetermined adhesive is dispensed on the first specified material paper to perform adhesion measurement in the present invention.

[0031] Finally, the adhesive strength is measured. The glue placement seat 22 is provided with an adjusting foot 23 for connecting with the glue placement platform 2, so that the glue placement platform 2 is arranged in parallel with the measuring head 54; the glue placement plate 21 is an elastic member, so that the measuring head 54 and the glue placement platform 2 will not directly collide to cause damage and measurement errors; finally, after the measuring head 54 is separated from the glue placement platform 2 for the first time to measure the initial adhesive strength, the measuring head 54 can be lowered and raised multiple times to repeatedly measure the continuous adhesive strength.

[0032] Embodiment 2: Still refer to Figures 1 to 3 , is only one of the embodiments of the present invention. On the basis of Embodiment 1, in a paper cigarette material adhesion measuring device of the present invention, the upper end of the glue injection cylinder 11 is connected to a glue dispenser through a glue injection tube, and the glue dispenser is an MS-1 type ECO glue dispenser; here, the MS-1 type ECO glue dispenser squeezes the adhesive into the glue injection cylinder 11 through the glue injection tube by pressure injection, and glues the glue injection cylinder 11 from the lower end thereof to the glue placing plate 21 of the glue placing table 2.

[0033] Here, there are two conventional dispensing methods. The first is to dispense a predetermined volume of adhesive onto the glue plate 21 by directly squeezing it; the second is to control the dispensing of a predetermined amount of adhesive onto the glue plate 21 by controlling the pressure application time; since the amount of glue dispensed each time in the first method is difficult to control, the second dispensing method is adopted in the present invention. For example, each time the glue is dispensed, the glue dispenser works at a predetermined pressure for 0.06 seconds to dispense a predetermined amount of adhesive onto the glue plate 21. In this way, the amount of glue dispensed each time is controllable and the same. Of course, this is under the premise that the adhesive is fully prepared, uniform, and has no sedimentation or stratification.

[0034] Generally speaking, the densities of several conventional types of adhesives are very close. With the same pressure application time, the dispensing amounts of different adhesives are almost the same. Of course, if this error also needs to be eliminated, a sample of the adhesive can be obtained before dispensing the adhesive, and the performance of the adhesive can be measured, including volume and mass, to obtain its density. In this way, the precise dispensing amount can be calculated based on the density, dispensing machine pressure, dispensing machine working time and the diameter of the injection tube, while the dispensing amount can be controlled each time.

[0035] In the present invention, a constant temperature heating chamber is provided on the outside of the glue injection tube. Since there are many types of adhesives, some of which are room temperature adhesives and some of which are hot melt adhesives, it is necessary to ensure that the adhesive maintains a constant optimal temperature. By setting up a constant temperature heating chamber, a stable higher temperature can be maintained for this type of hot melt adhesive to ensure the functional integrity of the adhesive during dispensing.

[0036] In addition, an auxiliary light source 121 is provided on the lower side of the functional probe 12. The auxiliary light source 121 is a ring-shaped light source or a bowl-shaped light source, so that the auxiliary light source 121 surrounds the lower side of the functional probe 12 to illuminate the lower side, thereby making it easier for the functional probe 12 to obtain image information at the glue plate.

[0037] The glue plate 21 is an elastic plate, which has two advantages. The first is that the glue injection cylinder 11 and the adhesion test head will not collide when they contact the glue plate 21, and the glue dispensing is not easily damaged, and the adhesion test is not easily damaged; the second is that it is convenient for the adhesion test head to squeeze and generate force, and it is more convenient to accurately obtain the adhesion test data.

[0038] The present invention further includes a second horizontal slide rail 8, on which a support plate 81 is arranged, the support plate 81 is fixedly connected to the vertical slide rail 3, and the second horizontal slide rail 8 is provided with a third motor 82 for driving the support plate 81 to slide along the second horizontal slide rail 8.

[0039] Here, the horizontal slide rail 4 is vertically arranged with the second horizontal slide rail 8; thus, the vertical slide rail 3, the horizontal slide rail 4 and the second horizontal slide rail 8 form three mutually perpendicular structures, so that the dispensing position can be controlled in three-dimensional directions to ensure the accuracy of the dispensing position.

[0040] Similarly, a first motor 31 for driving the sliding riser 13 to slide along the vertical rail 3 is disposed at the end of the vertical rail 3 ; a second motor 41 for driving the glue holder 22 to slide along the horizontal rail 4 is disposed at the end of the horizontal rail 4 .

[0041] It should be noted that the connecting line between the glue injection cylinder 11 and the functional probe 12 is arranged horizontally with the second horizontal slide rail 8. If the functional probe 12 is located directly above the glue plate 21, it is only necessary to move the glue injection part 1 along the second horizontal slide rail 8 by a predetermined distance (the predetermined distance is the distance between the glue injection cylinder 11 and the functional probe 12) to ensure that the glue injection cylinder 11 is located directly above the glue plate 21.

[0042] Embodiment 3: Still refer to Figures 1 to 3 , which is only one embodiment of the present invention. On the basis of any of the above embodiments, in a paper cigarette material adhesion measuring device of the present invention, the measuring head 54 and the extension column 53 are both made of steel, ensuring that the measuring head 54 has sufficient strength and the force at the measuring head 54 can be effectively transmitted to the sensor in the measuring platform 51.

[0043] In the present invention, the lower end of the extension column 53 is provided with an internal thread opening, and the upper end of the measuring head 54 is provided with an external thread opening for matching with the internal thread opening, ensuring that the measuring head 54 is fixedly installed without shaking to avoid measurement data errors.

[0044] In the present invention, the number of the adjusting feet 23 is at least three, which can fully adjust the glue placing platform 2 horizontally, so that the glue placing plate 21 is parallel to the lower surface of the measuring head 54 .

[0045] The rubber mounting seat 22 is provided with a locking buckle 24 for connecting with the horizontal slide rail 4; When the glue placing platform 2 needs to be displaced, the locking buckle is released; after the displacement of the glue placing platform 2 is completed, the locking buckle is locked to prevent the glue placing platform 2 from moving.

[0046] As one of the embodiments of the present invention, it also includes a control unit 7, and the sensor, functional probe 12, dispensing machine, auxiliary light source 121, first motor 31, second motor 41 and third motor 82 are all electrically connected to the controller 7. The control unit 7 is provided with a display screen 71, and the display screen 71 displays a curve of the sensor sensing force that changes with time, so as to obtain the initial bonding force and continuous bonding force of the adhesive.

[0047] In the present invention, a lifting motor is provided at the vertical slide frame 52 , and the lifting motor is electrically connected to the control unit 7 .

[0048] Finally, it also includes a mounting base 6, and the measuring part 5 and the glue placing table 2 are both mounted on the mounting base 6, and a plurality of leveling feet 61 are arranged on the lower side of the mounting base 6. Here, the leveling feet 61 are used to adjust the level of the entire device, and to compensate for the undulating error of the placement ground, so that the entire measuring part 5 and the horizontal slide rail 4 are placed horizontally.

[0049] Here, the level of the entire measuring part 5 and the control part 7 can be adjusted first by the leveling foot 61 of the mounting base 6, so that the lower surface of the measuring head 54 is horizontally set and the measuring head 54 extends downward; then the level of the rubber plate 21 is adjusted by the adjusting foot 23, so that the rubber plate 21 and the measuring head 54 are horizontally set.

[0051] In the present invention, step S6 is also included: Steps S4 to S5 are repeatedly executed to measure the sensor readings at the moment when the measuring head is separated from the adhesive plate for multiple times, which is the continuous bonding strength of the adhesive. The present invention discloses a device for measuring the adhesive force of paper cigarette materials and a method for using the device. The glue placing platform can be displaced horizontally.
