Description

Technical Field

[0001] The utility model relates to the technical field of adhesive measurement, in particular to an adhesive measurement structure for paper cigarette materials. Background Art

[0002] Cigarette adhesives have achieved significant success 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 continue to expand, especially for paper cigarette packaging materials (such as tipping paper, cigarette box sheets, and seals) that have undergone coating and other processing. These materials are often post-processed with UV varnishes, UV inks, double-sided laminations, and extremely low-surface-energy coatings, posing new challenges to the bonding performance of adhesives.

[0003] The widespread use of new materials, technologies, and equipment in tobacco packaging materials has led to changes in their surface properties to meet the demands of new products. This, in turn, has created challenges in the compatibility of cigarette packaging materials with adhesives, leading to inconsistent quality in finished cigarettes. Currently, Hubei China Tobacco is focusing on expanding the application and scope of transfer-type tipping paper. However, compared to standard tipping paper, transfer-type tipping paper undergoes further processing on the finished paper surface, creating a new interface between the coating and printing chemicals. This interface is hydrophobic and impermeable, resulting in certain deficiencies in its fit during the cigarette-making process, impacting tobacco factory production efficiency. Previous research has shown that tipping paper's fit is highly correlated with paper type, with standard paper outperforming transfer-type tipping paper in quality issues such as adhesive absorption, sticking, and curling. Water absorption and contact angle are also highly correlated with tipping paper's efficiency and quality. Due to the rapid curing nature of adhesives, contact angle θ measurements are inaccurate. These tests have limitations and cannot fully reflect the performance of tipping paper on the machine. In addition, the adhesive strength 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 value of tobacco materials, and the numerical value varies greatly. The most influencing factor is the simulation of the adhesive bonding and detachment process. The existing technology has the following three problems: 1. The problem of measuring angle. The bottom surface of the measuring head cannot be guaranteed to be parallel to the upper surface of the glue-placing table that carries the adhesive. As a result, the measuring angle changes when the measuring head and the glue-placing table are bonded and detached, and the measurement accuracy decreases; 2. The problem of measuring position. When the bottom surface of the measuring head descends to contact the upper surface of the glue-placing table, a collision is inevitable. At the very least, it causes the position of the measuring head or the glue-placing table to change, resulting in a deviation in the measurement position; at worst, it causes damage to the measuring head or the glue-placing table; 3. The measurement period cannot be determined. The adhesion includes initial adhesion (initial adhesion) and continuous adhesion (delayed adhesion). The current adhesion measurement still relies on the operator to pick up the adhesive multiple times by hand, 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 necessary for us to design a reasonable and efficient adhesive measurement structure for paper cigarette materials. Utility Model Content

[0027] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0028] Technologies, methods, and systems known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, the technologies, methods, and systems should be considered part of the authorization specification.

[0029] Example 1: Figure 1The figure is only one of the embodiments of the present invention, a paper cigarette material adhesive measuring structure, including a measuring part 5 and a glue placing table 2, the lower side of the glue placing table 2 is set on the horizontal slide rail 4 through the glue placing seat 22, and at least a part of the horizontal slide rail 4 is set on the lower side of the measuring part 5, 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; a sensor for obtaining the tension at the lower end of the measuring head 54 is provided in the measuring table 51, and a glue placing plate 21 for placing adhesive is provided on the glue placing table 2, and the glue placing plate 21 is parallel to the lower surface of the measuring head 54.

[0030] In the present invention, a dot of adhesive is placed on the adhesive plate 21 of the adhesive placement platform 2, and then the adhesive placement platform 2 is moved to the lower side of the measuring part 5, and the measuring head 54 of the measuring part 5 is pressed downward until it contacts the adhesive plate 21. At this time, the adhesive adheres to the adhesive plate 21 and the measuring head 54, and then the measuring head 54 is lifted upward. The force used to lift the measuring head 54 to separate from the adhesive plate 21 is the bonding force of the adhesive.

[0031] First, the structure of the glue placement table 2. A glue placement plate 21 is provided on the glue placement table 2. The lower side of the glue placement table 2 is provided on the horizontal slide rail 4 through a glue placement seat 22. At least a part of the horizontal slide rail 4 is provided on the lower side of the measuring part 5. The glue placement seat 22 on the lower side of the glue placement table 2 slides on the horizontal slide rail 4. In fact, the glue placement table 2 slides to the glue dispensing position, and the specified adhesive is dispensed onto the glue placement plate 21. Then, the glue placement 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 placement plate 21.

[0032] Next is the structure of the measuring part 5, which includes a measuring platform 51, a vertical slide frame 52 for facilitating the sliding of the measuring platform 51, an extension column 53 arranged on the lower side of the measuring platform 51, and a measuring head 54 arranged at the lower end of the extension column 53. That is to say, the measuring platform 51 can slide up and down along the vertical slide frame 52, that is, it can be raised and lowered. An extension column 53 extends from the lower side of the measuring platform 51, and a measuring head 54 is installed at the lower end of the extension column 53. When the measuring platform 54 descends, the measuring head 54 extends downward to the glue plate 21 and contacts the adhesive. The measuring platform 54 then ascends. At this time, the measuring head 54 overcomes the adhesive force of the adhesive until the moment the measuring head 54 detaches from the glue plate 21. The force applied to the measuring head 54 is the adhesive force of the adhesive.

[0033] Therefore, a sensor for obtaining the tension at the lower end of the measuring head 54 is provided in the measuring platform 51 .

[0034] When the measuring head 54 is unloaded, the sensor reading is reset to zero. Then, when the measuring head 54 moves downward until it contacts the adhesive plate 21, the sensor reading is negative, which is the squeezing force of the measuring head 54 against the adhesive plate 21. Controlling this force can facilitate sufficient 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.

[0035] 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 measuring the adhesion strength, the adhesion strength of the adhesive is also measured between the measuring head and the test paper. The test paper is fixed to the adhesive plate 21. For example, clipboards are provided around the adhesive plate 21 to fix the test paper. After each test, the test paper needs to be replaced and the adhesive dispensing and measurement are repeated.

[0036] 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 can be dispensed on the first specified material paper to perform adhesion strength measurement in the present invention.

[0037] Finally, the adhesive strength is measured. The adhesive placement seat 22 is provided with an adjustment foot 23 for connecting to the adhesive placement platform 2, so that the adhesive placement platform 2 is arranged parallel to the measuring head 54; the adhesive placement plate 21 is an elastic member, so that the measuring head 54 and the adhesive placement platform 2 will not directly collide to cause damage and measurement errors; finally, after the measuring head 54 is separated from the adhesive placement platform 2 for the first time and the initial adhesive strength can be measured, the measuring head 54 can be lowered and raised multiple times to repeatedly measure the continuous adhesive strength.

[0038] Example 2, as Figures 1 to 3 The figure shown is only one embodiment of the present invention. On the basis of the first embodiment, in a paper cigarette material adhesive measuring structure of the present invention, the measuring head 54 and the extension column 53 are both made of steel, ensuring that the measuring head 54 is strong enough and the force at the measuring head 54 can be effectively transmitted to the sensor in the measuring platform 51.

[0039] In the present invention, the lower end of the extension column 53 is provided with an internal threaded opening, and the upper end of the measuring head 54 is provided with an external threaded opening for matching with the internal threaded opening, ensuring that the measuring head 54 is fixedly installed without shaking to avoid measurement data errors.

[0040] In the present invention, the number of the adjusting feet 23 is at least three, which can fully adjust the glue placement platform 2 horizontally, so that the glue placement plate 21 is parallel to the lower surface of the measuring head 54 .

[0041] Example 3, as Figures 1 to 3 The figure shown is only one embodiment of the present invention. Based on any of the above embodiments, in the adhesive measuring structure for paper cigarette materials of the present invention, the adhesive placement seat 22 is provided with a locking buckle 24 for connecting with the horizontal slide rail 4;

[0042] 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.

[0043] As one of the embodiments of the present invention, it also includes a control unit 7, the sensor is electrically connected to the control unit 7, and a display screen 71 is provided on the control unit 7. The display screen 71 displays a curve of the sensor sensing force that changes with time, thereby obtaining the initial bonding force and continuous bonding force of the adhesive.

[0044] 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 .

[0045] Finally, a mounting base 6 is also included, 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 provided 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 uneven error of the placement ground, so that the entire measuring part 5 and the horizontal slide rail 4 are placed horizontally.

[0046] 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 set horizontally 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 set horizontally.

[0047] The utility model discloses an adhesive measuring structure for paper cigarette materials. The structure is simple. A measuring head is arranged in parallel with an adhesive placing plate, and the adhesive is located on the adhesive placing plate. Then, the measuring head moves up and down to contact the adhesive on the adhesive placing plate, and presses down and lifts the adhesive. Adhesion force data is obtained by a mechanical sensor behind the measuring head. The adhesive placing plate performs effective buffering, and the measurement error is small. The adhesion force of the adhesive is accurately measured, and the measurement can be repeated multiple times, so that the initial adhesion force and delayed adhesion force can be effectively measured.

[0048] The present invention is not limited to the above specific embodiments, and various modifications and variations are possible. Any modification, equivalent replacement, improvement, etc. made to the above embodiments based on the technical essence of the present invention shall be included in the scope of protection of the present invention.
