Description

Technical Field

[0001] The present application relates to the technical field of flavors and fragrances, and in particular to a flavor and fragrance sampler. Background Art

[0002] Flavors and spices are commonly used additives in consumer products such as food, beverages, and cosmetics. Their main function is to enhance the flavor and aroma of the product. Flavors usually refer to compounds obtained through artificial synthesis or extraction from natural raw materials. They can be a single ingredient or a mixture of multiple ingredients. In contrast, spices mainly come from natural resources such as plants, animals or minerals, and have specific aromas and flavors. The reasonable use of flavors and spices can significantly improve the taste of the product and enhance the sensory experience of consumers.

[0003] Existing flavor and fragrance samplers are usually integrated structures, which include a sampling rod and a sampling head from top to bottom. When sampling flavors and fragrances, the operator holds the upper end of the sampling rod and extends the sampling head into the storage tank containing the flavors and fragrances to take samples. However, existing flavor and fragrance samplers have the following problems:

[0004] 1) Unstable sampling: When sampling, the existing sampler is prone to shaking due to the long sampling rod, resulting in unstable sampling. 2) Cross-contamination of flavors and fragrances: After sampling, the existing sampler will clean the sampling head, but it is difficult to clean the sampling head thoroughly, and there will still be trace amounts of flavors and fragrances remaining. When the sampler is used to sample other flavors and fragrances later, it is easy to cause cross-contamination, causing errors in subsequent analysis and detection. Therefore, how to improve the stability of sampling and reduce cross-contamination has become a problem of concern to technicians in this field. Utility Model Content

In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0074] The inner side mentioned in the present application is the side close to the supporting mechanism, and the outer side is the opposite side, that is, the side away from the supporting mechanism.

[0075] This application embodiment provides a flavor and fragrance sampler, see Figure 1 The flavor and fragrance sampler comprises: a supporting mechanism 1, an adjusting clamp plate 2, a bidirectional threaded rod 3, a driving mechanism 4, a sampling connection mechanism 5 and a sampling head 6; wherein,

[0076] The support mechanism 1 is provided with a component accommodating cavity inside; the component accommodating cavity is formed with rod outlets 1 communicating with the outside at both ends along its length direction;

[0077] There are two adjusting clamps 2, which are symmetrically arranged on both sides of the supporting mechanism 1 along the length direction; the adjusting clamps 2 include a sliding adjustment portion 21 arranged in the horizontal direction and a fitting portion 22 arranged in the vertical direction; the fitting portion 22 is formed by the end of the outer side of the sliding adjustment portion 21 extending vertically downward; the sliding adjustment portion 21 is slidably sleeved outside the rod outlet 1 in the horizontal direction; the inner cavity of the sliding adjustment portion 21 is provided with an internal threaded pipe sleeve 211;

[0078] The bidirectional threaded rod 3 is arranged in the component accommodating cavity, and its two ends extend outward through the rod outlet 1 into the inner cavity of the sliding adjustment part 21, and are screwed into the inner threaded sleeve 211; the thread segments at both ends of the bidirectional threaded rod 3 are symmetrically arranged, and the thread directions are opposite;

[0079] The driving mechanism 4 is connected to the bidirectional threaded rod 3 and is used to drive the bidirectional threaded rod 3 to rotate;

[0080] The sampling connection mechanism 5 is arranged in the middle of the bottom of the supporting mechanism 1;

[0081] The top of the sampling head 6 is detachably connected to the sampling connection mechanism 5 .

[0082] In the flavor and fragrance sampler provided in this embodiment, the component accommodating cavity of the support mechanism 1 is used to set the bidirectional threaded rod 3, and the bottom is used to fix the sampling connection mechanism 5, which plays the role of protecting the bidirectional threaded rod 3, supporting the adjustment clamping plate 2, and fixing the sampling connection mechanism 5. The threads on both sides of the bidirectional threaded rod 3 are in opposite directions, and both ends are screwed with the internal threaded sleeve 211 of the adjustment clamping plate 2, so when it rotates under the drive of the driving structure 4, it will drive the internal threaded sleeve 211 to move in the opposite direction, that is, the adjustment clamping plate 2 is driven to slide in the opposite direction through the internal threaded sleeve 211. The adjusting splint 2 is provided with a fitting portion 22 arranged vertically downward, so that the distance between the two fitting portions 22 can be adjusted by adjusting the adjusting splint 2 and moving it inward / outward at the same time, so that the fitting portion 22 of the adjusting splint 2 fits with the outer wall of the placement tank for flavors and fragrances, which helps to improve the stability of the sampler and ensure that it will not shake or move during the sampling process. At the same time, it can also be adjusted according to the size and shape of different placement tanks, so that it can adapt to various types of containers, thereby improving the flexibility and applicability of sampling.

[0083] As a preferred solution of this embodiment, in order to limit the maximum sliding stroke of the adjusting splint 2 to the outside and prevent the adjusting splint 2 from detaching from the supporting mechanism 1, an annular limiting protrusion 31 is provided at the ends of both ends of the above-mentioned two-way threaded rod 3; the outer diameter of the annular limiting protrusion 31 is larger than the inner diameter of the inner threaded sleeve 211. When the adjusting splint 2 slides outward to the maximum preset stroke, the annular limiting protrusion 31 limits the further movement of the inner threaded sleeve 211, thereby limiting the maximum sliding stroke of the adjusting splint 2 to the outside. More preferably, the length dimension of the inner cavity of the sliding adjusting portion 21 is larger than half of the length dimension of the supporting mechanism 1.

[0084] In addition, matching slide rails and slide grooves are preferably provided between the sliding adjustment portion 21 and the support mechanism 1, so as to guide the sliding and reduce the sliding friction. A gasket 221 is preferably provided on the inner side of the fitting portion 22. The gasket 221 can fill the small gap between the fitting portion 22 and the surface of the placement tank, thereby reducing the direct pressure of the clamping force on the workpiece surface, avoiding scratches, dents or other forms of damage, and also improving the uniformity and stability of the clamping. The number of gaskets 221 provided on each fitting portion 22 can be one, two or more, such as Figure 1 In the flavor and fragrance sampler shown, two gaskets 221 are vertically arranged on each fitting portion 22. The gaskets 221 can be nylon gaskets, rubber gaskets, etc.

[0085] The driving mechanism 4 is used to drive the bidirectional threaded rod 3 to rotate, for example, to drive it to rotate forward or reverse, thereby driving the adjusting splint 2 to slide inward / outward. Figure 1The driving mechanism 4 preferably includes: a vertical bevel gear 41, a horizontal bevel gear 42 and a crank 43; wherein the vertical bevel gear 41 is arranged in the middle of the bidirectional threaded rod 3; that is, the bidirectional threaded rod 3 forms the gear shaft of the vertical bevel gear 41; the horizontal bevel gear 42 meshes with the vertical bevel gear 41; an opening is provided on the top surface of the supporting mechanism 1, and the gear shaft of the horizontal bevel gear 42 passes through the opening and extends upward to be connected to the crank 43. Through the driving mechanism 4, the operator can control the movement direction and movement stroke of the two adjustment splints 2 by operating the crank 43.

[0086] The sampling connection mechanism 5 is used to fix the sampling head 6, and is detachably connected to the sampling head 6, thereby facilitating replacement of the sampling head 6. Different fragrances can be installed with different sampling heads 6, thus avoiding cross contamination between different flavors and fragrances and maintaining the purity and flexibility of sampling.

[0087] See also Figure 2 and Figure 3 The sampling connection mechanism 5 preferably includes: a support sleeve 51, a double eccentric wheel 52, a slider 53, a tension spring 54 and a clamping plate 55; wherein,

[0088] The support sleeve 51 is arranged at the middle of the bottom of the support mechanism 1; the support sleeve 51 is provided with a support plate 511 arranged in a horizontal direction, and the support plate 511 is provided with a sliding hole 512 along the length direction of the support mechanism 1;

[0089] The double eccentric wheel 52 is arranged above the support plate 511 in the horizontal direction; the axis of the double eccentric wheel 52 is provided with a rotating shaft 521 penetrating the double eccentric wheel 52 in the vertical direction; the bottom end of the rotating shaft 521 is connected to the support plate 511;

[0090] There are two sliders 53, which are symmetrically arranged on both sides of the double eccentric wheel 52 along the length direction of the support mechanism 1, and the surface of each slider 53 in contact with the double eccentric wheel 52 is an arc surface;

[0091] The tension spring 54 is arranged along the length direction of the support mechanism 1, and its two ends are respectively connected to the two sliders 53;

[0092] The top of the clamping plate 55 passes through a sliding hole 512 and is connected to the bottom surface of the slider 53; a clamping protrusion is provided on the inner side of the clamping plate 55;

[0093] The top of the sampling head 6 is provided with a snap-in groove matched with the snap-in protrusion.

[0094] In the above-mentioned sampling connection mechanism 5, by rotating the double eccentric wheel 52, the double eccentric wheel 52 pushes the two sliders 53 to increase the distance between the two sliders 53, and the distance between the two clamping plates 55 increases accordingly. At this time, the clamping plate 55 and the top of the sampling head 6 lose the tight clamping thrust, and the sampling head 6 can be disassembled. When the sampling head 6 is replaced, the external force on the rotation of the double eccentric wheel 52 is removed, and the slider 53 moves inward under the restoring force of the tension spring 54. The double eccentric wheel 52 also automatically rotates to the state where the distance between the two sliders 53 is the smallest under the thrust of the two sliders 53, that is, Figure 3 The state shown. At this time, the clamping plate 55 is tightly clamped with the top of the sampling head 6, and the installation is completed. By adopting the sampling connection mechanism 5, the flavor and fragrance sampler can be quickly replaced with samplers of different types or specifications, and the operation is simple, saving time for replacing the sampler.

[0095] In order to facilitate the connection between the tension spring 54 and the slider 53 and improve the reliability of the entire mechanism, see Figure 3 The slider 53 is provided with connecting parts on both sides of the width direction of the support mechanism 1; there are two tension springs 54, and the two ends of each tension spring 54 are respectively connected to the connecting parts on the same side of the two sliders 53. In addition, in order to facilitate the operator to rotate the double eccentric wheel 52, the sampling connection mechanism 5 preferably also includes: a pull rod, which is arranged in the horizontal direction, and one end is connected to the rotating shaft 521 of the double eccentric wheel 52. When the double eccentric wheel 52 needs to be rotated, the operator only needs to pull the pull rod, and the double eccentric wheel 52 can be easily rotated by lever effect.

[0096] See also Figure 4 As a preferred solution of this embodiment, the above-mentioned flavor and fragrance sampler also preferably includes a lofting mechanism 7, which is symmetrically arranged on both sides of the support mechanism 1 along the width direction; the lofting mechanism 7 includes: a hinged plate 71 and a lofting plate 72; the hinged plates 71 are two, which are respectively hinged to the same side of the adjustment clamping plate 2, and the hinge axis is arranged along the length direction of the support mechanism 1; the hinged plate 71 is provided with a slide plate arranged along the length direction of the support mechanism 1; the lofting plate 72 is sleeved outside the slide plate, and the slide plate can move inside the lofting plate 72 along the length direction of the support mechanism 1.

[0097] When the adjusting clamp plate 2 slides, the hinge plate 71 is driven to move accordingly, and the slide plate slides inside the sample plate 72, so that the adjusting clamp plate 2 drives the hinge plate 71 to slide synchronously, and the hinge plate 71 slides inside the sample plate 72 accordingly, and the position of the sample plate 72 remains basically unchanged at this time. Since the hinge axis of the hinge plate 71 and the adjusting clamp plate 2 is arranged along the length direction of the support mechanism 1, the hinge plate 71 can swing in the vertical direction. The operator can change the arrangement angle of the sample plate 72 by rotating the hinge plate 71 along the vertical plane, for example, adjusting it to a horizontal position to facilitate the operator to place the flavor and fragrance samples after sampling, so as to facilitate the operator to easily take them, and then the flavor and fragrance samples of different types or batches can be placed separately.

[0098] When the sampler is not needed, the samplers 7 on both sides of the support mechanism 1 can be folded upward or downward to reduce the area occupied by the device. Preferably, a handle 721 is also provided on the sampler plate 72, and the handle 721 makes the flavor and fragrance sampler more convenient and quick to carry. Furthermore, the handle 721 is preferably provided on the outer side of the sampler plate 72.

[0099] From the above content, it can be seen that the flavor and fragrance sampler provided by the embodiment of the utility model has the following advantages:

[0100] 1. After the driving mechanism of the flavor and fragrance sampler drives the bidirectional threaded rod to rotate, the bidirectional threaded rod can drive the adjusting clamp to move inward / outward at the same time through the internal threaded sleeve, thereby adjusting the distance between the fitting parts of the two adjusting clamps so that the fitting parts fit the outer wall of the placement tank, which helps to improve the stability of the sampler and ensure that it will not shake or move during the sampling process. At the same time, it can also be adjusted according to the size and shape of different placement tanks, so that it can adapt to various types of containers, thereby improving the flexibility and applicability of sampling.

[0101] 2. The sampling connection mechanism and the sampling head of the flavor and fragrance sampler are detachably connected, which makes it easy to replace the sampling head. Different sampling heads can be installed for different flavors, avoiding cross contamination between different flavors and fragrances and maintaining the purity and flexibility of sampling.

[0102] 3. Furthermore, by providing the above-mentioned sampling connection mechanism including the support sleeve, double eccentric wheels, slider, tension spring and clamping plate, the flavor and fragrance sampler can be quickly replaced with samplers of different types or specifications, and the operation is simple, saving the time of replacing the sampler.

[0103] 4. Furthermore, by setting the above-mentioned sample placing mechanism, the operator can change the arrangement angle of the sample placing plate by rotating the hinge plate along the vertical plane, for example, adjusting it to a horizontal position to facilitate the operator to place the flavor and fragrance samples after sampling, so as to facilitate the operator to easily take them, and further, the flavor and fragrance samples of different types or batches can be placed separately. When sample placing is not required, the sample placing mechanisms on both sides of the support mechanism can be folded up to reduce the area occupied by the equipment.
