Description

Technical Field

[0001] The utility model belongs to the technical field of physical and chemical inspection of food additive residues in paper, and particularly relates to a material taking device for extracting sweeteners on the surface of tipping paper. Background Art

[0002] Sweeteners, as an important type of food additives, are widely used in the modern food industry to enhance the taste and flavor of food. In particular, non-sugar sweeteners have become an ideal substitute for traditional sucrose due to their high sweetness, low calories, and lack of metabolic processes. However, traditional methods have certain limitations when using sweeteners. For example, although food additives are harmless to humans within the prescribed dosage range, excessive use may cause various forms of toxicity problems.

[0003] At present, although many countries have adopted strict restriction policies on the use of sweeteners such as saccharin sodium and cyclamate and formulated corresponding standards, how to effectively manage and control the use of sweeteners while ensuring food safety is still a major challenge facing the industry.

[0004] Chinese patent CN210427050U discloses a material extraction device for extracting sweeteners from the surface of tipping paper, comprising: a support part, a plastic film, a fixing part, a double-sided adhesive tape, a food packaging paper sample, and a friction paper; the plastic film is covered on the support part; the support part and the plastic film are fixed to each other by the fixing part; the food packaging paper sample to be tested is pasted on the plastic film by the double-sided adhesive tape. Then, the friction paper is clamped with tweezers, and the surface area of ​​the food packaging paper sample to be tested is rubbed back and forth with appropriate force to extract the sweeteners from the paper surface. The extraction device can efficiently collect the sweeteners from the paper surface, collect the friction paper containing the target object, and use it for chromatographic instrument analysis after aqueous solution extraction, and then perform quantitative analysis on the target object.

[0005] Although the material extraction device disclosed in the above scheme can realize the extraction of sweeteners on the surface of paper and is suitable for subsequent chromatographic instrument analysis, the method of manually clamping the friction paper with tweezers and rubbing it back and forth in this technical scheme is difficult to ensure the accuracy and repeatability of the operation.

[0006] At the same time, the inconsistency of manual operation force and speed may lead to differences in the effect of each extraction, affecting the accuracy and comparability of the experimental results. It is also impossible to accurately control the pressure applied to the friction paper. Too much or too little force may damage the food packaging paper sample or lead to low extraction efficiency.

[0007] Therefore, we propose a material taking device for extracting sweetener from the surface of tipping paper. Utility Model Content

[0008] The utility model aims to provide a material taking device for extracting sweetener from the surface of tipping paper, so as to solve the problems raised in the above background technology.

[0011] Wherein, the counterweight block can be a weight between 100 grams and 500 grams.

[0012] Furthermore, a ruler or scale lines are provided on the outer side wall of the U-shaped lifting plate.

[0013] Preferably, the friction paper has a thickness of 0.1-0.5 mm.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-Figure 3The utility model proposes a technical solution of a material taking device for extracting sweeteners on the surface of tipping paper, comprising: a material taking device body 1, a positioning platform 2, tipping paper 3, a pressing mechanism 4 and friction paper 5, wherein the friction paper 5 is arranged above the positioning platform 2 and partially extends axially to the outside of the positioning platform 2, the material taking device body 1 has at least one pressing mechanism 4 and a fixed mounting frame 6 for locating the position of the pressing mechanism 4, the fixed mounting frame 6 is arranged on the periphery of the positioning platform 2, the pressing mechanism 4 is slidably arranged in the fixed mounting frame 6, and the tipping paper 3 is adhered to the lower bottom surface of the pressing mechanism 4, so as to realize contact and separation with the friction paper 5 through the up and down movement of the pressing mechanism 4.

[0027] In this embodiment, the sliding fit of the pressing mechanism 4 in the fixed mounting frame 6 makes its up and down movement stable, reduces deviation and vibration, and thus ensures the repeatability and reliability of each contact and separation process. This is crucial to maintaining product quality consistency. At the same time, by arranging the fixed mounting frame 6 around the positioning platform 2, an accurate sliding track is provided for the pressing mechanism 4. Such a design not only ensures that the friction paper 5 and the tipping paper 3 can be accurately aligned, but also facilitates the operator to quickly replace different sizes or types of paper, thereby improving the applicability and flexibility of the equipment.

[0028] On the other hand, since the tipping paper 3 is directly adhered to the lower bottom surface of the pressing mechanism 4, when the pressing mechanism 4 moves downward, the pressure provided by the counterweight 7 is evenly transmitted to the tipping paper 3 through the pressing plate 10, thereby ensuring full and even contact with the friction paper 5 and improving the extraction effect.

[0029] In addition, the bottom surface of the pressing mechanism can be designed to be flat or in accordance with the shape of the tipping paper curved surface to ensure effective contact between the friction paper and the tipping paper surface. The part of the friction paper that extends axially outside the positioning platform facilitates the replacement and collection of the friction paper, allowing it to be quickly cleaned and replaced between different tests, reducing the risk of cross contamination.

[0030] In one embodiment, the pressing mechanism 4 has at least one U-shaped lifting plate 15 and a counterweight 7. The side slides 8 on both sides of the U-shaped lifting plate 15 are clearance-matched with the alignment holes 9 opened on the upper surface of the fixed mounting frame 6. The counterweight 7 is located above the lower pressing plate 10 in the middle of the U-shaped lifting plate 15, and is used to provide sufficient pressure to promote the contact and separation of the friction paper 5 and the surface of the tipping paper 3.

[0031] The counterweight 7 may be a weight between 100 grams and 500 grams, and the friction paper 5 may have a thickness between 0.1 mm and 0.5 mm.

[0032] In this embodiment, by using a counterweight 7 of 100 grams to 500 grams, appropriate pressure can be applied according to different materials and thicknesses of the friction paper 5 and the tipping paper 3, which can ensure effective contact and avoid damage to the paper. The design of the U-shaped lifting plate 15 combines the weight of the counterweight 7 to provide a stable downward pressing structure, reduce vibration or deviation that may occur during the extraction process, and thus maintain stable contact between the friction paper 5 and the tipping paper 3.

[0033] Specifically, when the pressing mechanism 4 is at the starting position, the side slide plate 8 of the U-shaped lifting plate 15 is in clearance with the alignment hole 9 provided on the upper surface of the fixed mounting frame 6, ensuring that the pressing mechanism 4 can smoothly slide up and down in the fixed mounting frame 6. At this time, the counterweight 7 is statically placed inside the U-shaped lifting plate 15.

[0034] When the friction paper 5 needs to contact the tipping paper 3, the pressing mechanism 4 starts to move downward through a certain mechanism (such as manual, electric or pneumatic). The U-shaped lifting plate 15 slides downward along the guide of the fixed mounting frame 6, and the counterweight 7 starts to apply pressure to the tipping paper 3 above the lower pressing plate 10 in the middle of the pressure plate 6 due to its own weight without applying any pressure.

[0035] As the lower pressing plate 10 gradually approaches the tipping paper 3 on the positioning platform 2, the weight of the counterweight 7 begins to be transferred to the friction paper 5 through the lower pressing plate 10, so that the friction paper 5 contacts the surface of the tipping paper 3. Since the weight of the counterweight 7 is preset between 100 grams and 500 grams, the applied pressure can ensure effective contact without being too heavy to cause damage to the paper.

[0036] After the friction paper 5 contacts the tipping paper 3, if the two need to be separated, the pressing mechanism 4 may be designed to continue to move downward or maintain a certain pressure state, depending on the specific extraction process requirements. During the whole process, the structural stability provided by the U-shaped lifting plate 15 and the uniform pressure applied by the counterweight 7 work together to maintain stable contact between the friction paper 5 and the tipping paper 3.

[0037] After the contact and separation actions are completed, the pressing mechanism 4 will be lifted back to the initial position to prepare for the next operation. The U-shaped lifting plate 15 slides upward along the fixed mounting frame 6, and the counterweight 7 rises and separates from the pressing plate 10, reducing the pressure on the paper 3.

[0038] In one embodiment, a ruler or scale line is provided on the outer wall of the U-shaped lifting plate 15 to provide a visual reference to ensure that the height reached by the pressing mechanism 4 is consistent each time the operation is performed, which helps to ensure the repeatability and reliability of the extraction process.

[0039] In one embodiment, the positioning platform 2 includes: a platform base plate 11, an elastic plate 12, a mounting side plate 13 and a support spring 14. The number of the mounting side plates 13 is at least 2, which are symmetrically arranged at both ends of the platform base plate 11. The elastic plate 12 is fixedly arranged between the above-mentioned two mounting side plates 13. The support springs 14 are evenly distributed in the middle of the platform base plate 11 and are located between the platform base plate 11 and the elastic plate 12.

[0040] In this embodiment, on the one hand, the support springs 14 can be evenly distributed in the middle of the platform bottom plate 11 to ensure that the pressure applied to the friction paper 5 is uniform, which helps to achieve uniform contact and separation and avoid damage to the tipping paper 3 or the friction paper 5 due to excessive local pressure. At the same time, the symmetrical arrangement of the two mounting side plates 13 enhances the structural stability of the entire positioning platform 2, so that during operation, especially when the pressing mechanism 4 moves, the platform can remain stable, reducing errors caused by vibration or movement of the equipment.

[0041] On the other hand, the elastic plate 12 is fixed between the mounting side plates 13, providing a flexible support surface, which can absorb and alleviate the impact generated by the pressing mechanism 4 during operation, and protect the tipping paper 3 and the friction paper 5 from damage.

[0042] In addition, the positioning platform 2 further includes: a plurality of adjustment screws, which penetrate the platform bottom plate 11 and engage with the elastic plate 12 , and are used to fine-tune the distance between the elastic plate 12 and the platform bottom plate 11 .

[0043] The specific connection between the adjusting screw and the elastic plate 12 is known to those skilled in the art and is not shown in the drawings.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
