[0001] This application relates to the field of sample chopping device technology, and in particular to a dried fruit sample chopping device. Background Technology

[0002] Currently, in the process of chemical composition analysis, microbial detection, and physical property determination of dried fruit products such as goji berries, scissors or small experimental sample shredders are usually used to chop the dried fruit samples so that the dried fruit samples can better meet the requirements of each test item, thereby improving the accuracy and efficiency of the test.

[0003] However, using scissors to chop samples is inefficient, and the chopped samples left aside easily absorb moisture from the environment, affecting the sample properties and the accuracy of the test results. Furthermore, small-scale sample shredders generate heat during operation, which may cause the shredded samples to stick together, thus compromising sample homogeneity and ultimately affecting the test results. Utility Model Content

[0004] Therefore, it is necessary to provide a fruit sample chopping device to address the problems of low chopping efficiency, easy adhesion of pulverized material, and impact on detection results.

[0007] The cutting mechanism is provided with a plurality of cutting sections, and each cutting section is provided in correspondence with a sample placement position.

[0008] The cutting mechanism is configured to separate the cutting part from the sample placement position in a first state and to insert the cutting part into the sample placement position in a second state.

[0009] In one embodiment, the first surface is provided with a plurality of feeding grooves arranged sequentially along a first direction, and each feeding groove has a plurality of sample placement positions arranged sequentially along a second direction, wherein the first direction is perpendicular to the second direction.

[0010] In one embodiment, the cutting part is a cross-cutting part, and a plurality of cutting openings are provided between two adjacent feeding grooves in sequence along the second direction. The sample placement position is located between two adjacent cutting openings along the first direction.

[0011] In one embodiment, the distance between two adjacent cuts along the second direction is greater than 1.5 cm and less than 2.5 cm.

[0012] In one embodiment, the discharge trough is an arc-shaped discharge trough.

[0013] In one embodiment, the diameter of the arc-shaped feeding trough is greater than 0.8 cm and less than 1.5 cm.

[0014] In one embodiment, the cutting mechanism is rotatably connected to the feeding mechanism.

[0015] In one embodiment, the feeding mechanism includes a first housing and a feeding box, the feeding box being detachably connected to the first housing, and the first surface being located on the side of the feeding box opposite to the first housing.

[0016] In one embodiment, the cutting mechanism includes a second housing and a cutter assembly, the cutter assembly being detachably connected to the second housing.

[0017] In one embodiment, the cutting portion is provided with an anti-stick coating; and / or, the sample placement position is provided with an anti-stick coating.

[0018] The aforementioned dried fruit sample chopping device can simultaneously accommodate several dried fruit samples through several sample placement positions on the feeding mechanism.

[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0033] Currently, in the process of chemical composition analysis (nutritional component detection, additive detection, etc.), microbial detection (total bacterial count detection, mold and yeast detection, etc.), and physical property determination (moisture content determination, hardness, elasticity and other texture characteristics determination) of dried fruit products such as goji berries, scissors or small test sample shredders are usually used to chop the dried fruit samples so that the dried fruit samples can better meet the requirements of each test item, thereby improving the accuracy and efficiency of the test.

[0034] Understandably, many testing instruments have specific requirements for sample morphology. For example, in near-infrared spectroscopy, samples need to have a certain degree of uniformity and suitable particle size so that light can evenly irradiate the sample surface and obtain accurate spectral information. Chopped dried fruit samples better meet the instrument's sample requirements, enabling the instrument to function properly and obtain reliable detection data. In some chemical tests, such as extracting active ingredients (e.g., polyphenols) from dried fruit, chopped dried fruit has a larger surface area, allowing solvents to penetrate more easily, thus improving extraction efficiency. Furthermore, chopped samples are easier to process in subsequent steps such as filtration and centrifugation, reducing sample loss and errors. Shearing goji berries significantly increases their surface area, allowing the chemical reagents or solvents required for detection to come into more complete contact with the berries. For example, when detecting pesticide residues or heavy metal content in goji berries, sheared goji berries can release their internal components more quickly, thus shortening detection time and improving detection efficiency. For some testing items that require the extraction of internal components from wolfberries (such as the determination of wolfberry polysaccharides and wolfberry flavonoids), shearing can destroy the cell structure, accelerate the release of active ingredients, and thus improve the extraction efficiency.

[0035] However, current methods of shredding with scissors and grinding with pulverizers have shortcomings. Scissors are inefficient, and shredded samples left aside easily absorb moisture from the environment, affecting sample properties and the accuracy of test results. Small-scale experimental sample pulverizers generate heat during operation, which may cause the pulverized samples to stick together, compromising sample homogeneity and ultimately affecting test results.

[0036] Therefore, this application provides a dried fruit sample chopping device that can reduce the probability of adhesion while ensuring chopping efficiency, thereby ensuring the detection effect, in order to solve the above-mentioned technical problems.

[0037] See Figures 1-3 One embodiment of this application provides a dried fruit sample chopping device, including a feeding mechanism 1 and a cutting mechanism 2. The feeding mechanism 1 is used to simultaneously place multiple dried fruit samples 3, and the cutting mechanism 2 is used to simultaneously cut the multiple dried fruit samples 3, so as to reduce the probability of adhesion while ensuring chopping efficiency, thereby ensuring the detection effect.

[0038] For specific settings, please refer to Figures 1-2 The feeding mechanism 1 has a first surface 11 and a second surface 12 that are opposite to each other. The first surface 11 is provided with a plurality of spaced sample placement positions 13. The feeding mechanism 1 can be placed on the holding surface of the support device, so that its second surface 12 is in contact with the holding surface, so as to accommodate and position the dried fruit sample 3 through the sample placement positions 13.

[0039] The cutting mechanism 2 is provided with a plurality of cutting parts 23, and each cutting part 23 is correspondingly provided with a sample placement position 13, so that each cutting part 23 can be inserted into a sample placement position 13 to cut the dried fruit sample 3 in the sample placement position 13.

[0040] Specifically, the cutting mechanism 2 is configured in a first state to separate the cutting part 23 from the sample placement position 13 so that the dried fruit sample 3 can be placed on the sample placement position 13. Furthermore, the cutting mechanism 2 is configured in a second state to insert the cutting part 23 into the sample placement position 13 to cut the dried fruit sample 3 located within the sample placement position 13.

[0041] For more details, please refer to Figure 2 In one embodiment, the cutting mechanism 2 is rotatably connected to the feeding mechanism 1. The operator can separate the cutting part 23 from the sample placement position 13 or insert it into the sample placement position 13 by rotating the cutting mechanism 2 around the feeding mechanism 1.

[0042] In another embodiment, see [reference] Figure 1 The cutting mechanism 2 is detachably connected to the feeding mechanism 1. An operator can move the cutting mechanism 2 so that its cutting part 23 approaches or moves away from the first surface 11 of the feeding mechanism 1, thereby separating the cutting part 23 from the sample placement position 13 or inserting it into the sample placement position 13. For example, the cutting mechanism 2 is fastened to the feeding mechanism 1. An operator can separate the cutting part 23 from the sample placement position 13 by removing the cutting mechanism 2 from the feeding mechanism 1, and insert the cutting part 23 into the sample placement position 13 by fastening the cutting mechanism 2 onto the feeding mechanism 1.

[0043] In addition, to facilitate the movement of the cutting mechanism 2, in some embodiments, the cutting mechanism 2 is provided with at least one handle. The handle can be provided on the side of the cutting mechanism 2 away from the cutting part 23, or on the side of the cutting mechanism 2 perpendicular to the plane where the cutting part 23 is located.

[0044] In summary, the dried fruit sample chopping device of this application simultaneously accommodates several dried fruit samples 3 via several sample placement positions 13 on the feeding mechanism 1. When the cutting mechanism 2 moves several cutting parts 23, these parts can be simultaneously inserted into the sample placement positions 13, thus achieving simultaneous cutting of the dried fruit samples 3. Compared to scissor cutting, the dried fruit sample chopping device of this application has higher chopping efficiency, allowing several dried fruit samples 3 to be chopped simultaneously. This solves the problem that samples placed aside after chopping easily absorb moisture from the environment, affecting the sample properties and the accuracy of test results. Compared to the pulverization method of small-scale experimental sample pulverizers, the dried fruit sample chopping device of this application does not cause the pulverized samples to stick together due to heat generated during operation, solving the problem that pulverization by small-scale experimental sample pulverizers easily damages the uniformity of the samples, ultimately affecting the test results.

[0045] See Figures 2-3 In one embodiment, a plurality of feeding slots 14 are provided on the first surface 11 in sequence along a first direction, and each feeding slot 14 has a plurality of sample placement positions 13 in sequence along a second direction, the first direction being perpendicular to the second direction. Compared to directly providing a plurality of slot-shaped sample placement positions 13 on the first surface 11, the structure of providing a plurality of feeding slots 14 on the first surface 11 and having a plurality of sample placement positions 13 in each feeding slot 14 is simpler. When placing dried fruit samples 3, multiple dried fruit samples 3 can be directly placed into one feeding slot 14, and then the multiple dried fruit samples 3 in the feeding slot 14 can be arranged in sequence in the plurality of sample placement positions 13, without having to place several dried fruit samples 3 one by one in the plurality of slot-shaped sample placement positions 13, which is convenient for placement operation.

[0046] Understandably, if the dried fruit samples 3 are placed one by one into the multiple trough-shaped sample placement positions 13, the operator would need to repeatedly perform the actions of taking samples and placing them, which could easily lead to fatigue and operational errors. However, placing the samples into the feeding trough 14 first, and then performing subsequent operations in a unified manner, can reduce repetitive actions and improve work efficiency. Furthermore, placing the dried fruit samples 3 one by one into the trough-shaped sample placement positions 13 requires individual operation, occupying the sample placement positions 13 for a considerable amount of time. However, placing the samples into the feeding trough 14 first, and then placing them sequentially, can quickly complete the sample filling, reduce the time occupied by the sample placement positions 13, and improve the utilization rate of the equipment.

[0047] See Figure 1 and Figure 4In one embodiment, the cutting part 23 is a cross-cutting part 23, and a plurality of cutting openings 15 are arranged sequentially along the second direction between two adjacent feeding troughs 14. The sample placement position 13 is located between two adjacent cutting openings 15 along the first direction. By setting the cutting openings 15 between two adjacent feeding troughs 14, when the cutting mechanism 2 moves the cross-cutting part 23, the cross-cutting part 23 can be inserted into both the cutting opening 15 and the sample placement position 13 at the same time, so that the dried fruit sample 3 in the sample placement position 13 can be cross-cut, and the dried fruit sample 3 can be divided into four parts.

[0048] Specifically, the distance between two adjacent cuts 15 along the second direction is greater than 1.5cm and less than 2.5cm. More specifically, the distance between two adjacent cuts 15 along the second direction is 2cm. This distance is reasonably suitable for dried fruit sample 3 of type goji berries, ensuring the placement effect of dried fruit sample 3 while avoiding wasted space.

[0049] Understandably, dried goji berries are relatively small, typically around 1-2 cm in length. A width of 2 cm easily accommodates a single dried goji berry, ensuring smooth placement and removal while preventing deformation or damage due to insufficient space. If the sample placement area 13 were too wide, although it could accommodate the dried goji berries, it would waste space and reduce its utilization rate. A width of 2 cm maximizes space utilization while meeting placement requirements, increasing the density of the sample placement area 13. Furthermore, the 2 cm width is moderate, allowing operators to easily place or remove the dried goji berries into or from the sample placement area 13 using tweezers or fingers, without the difficulty of operation due to narrowness, effectively improving sample processing efficiency.

[0050] See Figures 1-2 In one embodiment, the feeding trough 14 is an arc-shaped feeding trough 14. The arc surface of the arc-shaped feeding trough 14 makes it easier to position the dried fruit sample 3 in the arc-shaped feeding trough 14, so that it naturally fits the shape of the dried fruit and enhances the stability of the sample.

[0051] Specifically, the discharge trough 14 is an arc-shaped discharge trough 14 with its opening opened on the first surface 11. The opening of the arc-shaped discharge trough 14 has a first side parallel to the first direction and a second side parallel to the second direction. The length of the second side is greater than the length of the first side.

[0052] Understandably, many dried fruits (such as goji berries and raisins) have a certain degree of curvature or irregular shape. The curved surface of the arc-shaped feeding trough 14 can naturally conform to the shape of these dried fruits, allowing them to be better "embedded" in the trough when placed, thereby reducing movement or rolling within the trough. Because the arc-shaped trough has a higher degree of matching with the shape of the dried fruits, operators do not need to adjust the position of the dried fruits excessively when placing them, ensuring they are stably placed in the trough. This greatly improves the efficiency of sample placement and reduces the time wasted on adjusting the position.

[0053] Furthermore, the curved surface of the arc-shaped feeding groove 14 provides better support for the dried fruit, reducing its shaking during placement and inspection. Within the arc-shaped groove, the dried fruit, constrained by the curved surface, is less prone to displacement due to external forces (such as vibration or airflow). This stability ensures the sample remains in the predetermined position throughout the cutting process, avoiding cutting errors caused by sample displacement. The arc-shaped feeding groove 14 also allows operators to more easily pick up and place the dried fruit sample 3 using tweezers or fingers. Compared to straight grooves, the arc-shaped groove provides a more intuitive indication of whether the dried fruit has been correctly placed, thereby reducing operational errors caused by visual bias.

[0054] In one embodiment, the diameter of the arc-shaped feeding trough 14 is greater than 0.8 cm and less than 1.5 cm. Specifically, the diameter of the arc-shaped feeding trough 14 is 1 cm. This diameter is better suited for dried fruit sample 3, such as goji berries, to ensure the placement effect of the dried fruit sample 3 while avoiding space waste.

[0055] Understandably, dried goji berries are relatively small, typically around 5mm-10mm in diameter. The 1cm diameter of the arc-shaped feeding trough 14 can easily accommodate a single dried goji berry, ensuring smooth placement and removal while preventing deformation or damage due to insufficient space. If the diameter of the arc-shaped feeding trough 14 were too large, although it could accommodate the dried goji berries, it would waste space and reduce the utilization rate of the sample placement position 13. The 1cm diameter meets the placement requirements while maximizing space utilization to reduce the overall thickness of the device. Furthermore, the 1cm diameter is moderate, allowing operators to easily place or remove the dried goji berries into or from the sample placement position 13 using tweezers or fingers, without difficulty due to excessive depth, effectively improving sample processing efficiency.

[0056] See Figures 2-3In one embodiment, the feeding mechanism 1 includes a first housing 16 and a feeding box 17, which is detachably connected to the first housing 16. A first surface 11 is located on the side of the feeding box 17 facing away from the first housing 16, and multiple sample placement positions 13 are provided on the feeding box 17. The detachable connection facilitates cleaning of the feeding box 17, which has sample placement positions 13 for holding dried fruit samples 3.

[0057] Specifically, in the embodiments of this application, the first housing 16 is provided with a first mounting groove, and the material box 17 is fixed in the first mounting groove to achieve a detachable connection with the first housing 16.

[0058] In one embodiment, the cutting mechanism 2 includes a second housing 21 and a cutter assembly 22, the cutter assembly 22 being detachably connected to the second housing 21. This detachable connection facilitates the removal of the cutter assembly 22 from the second housing 21 for individual cleaning.

[0059] Specifically, in the embodiments of this application, the second housing 21 is provided with a second mounting groove, and the cutter assembly 22 is fixed in the second mounting groove to achieve a detachable connection with the second housing 21.

[0060] In one embodiment, the cutting section 23 and the sample placement position 13 are provided with an anti-stick coating to reduce the probability of adhesion after cutting. Specifically, the anti-stick coating can be a TiN (titanium nitride) coating, a TiCN (titanium carbonitride) coating, a TiAlN (titanium aluminum nitride) coating, or a DLC (diamond-like carbon) coating.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
