Abstract
Description
Technical Field
[0001] This utility model relates to a grinding device, specifically a grinding device for food testing, and belongs to the field of food testing technology. Background Technology
[0002] In existing food testing standards, for dry samples (grains, dried edible fungi, and dried aquatic animal products), the edible portion is required to be ground evenly in a mortar and pestle and sieved during sample preparation. A small amount of powder sample is then taken for subsequent testing (e.g., 0.5g to 2.5g of powder sample is weighed in wet digestion). However, in daily work, testing personnel often encounter situations where "there are many types of samples submitted for testing, and the amount of each sample is small." Therefore, relying entirely on manual grinding can easily lead to fatigue of testing personnel during long periods of operation, reducing the efficiency and quality of grinding.
[0003] In summary, how to propose a grinding device to address the aforementioned technical problems has become a pressing issue for those skilled in the art. Utility Model Content

[0024] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0025] Specific implementation method one: Combining Figures 1 to 4 This embodiment describes a grinding device for food testing, which includes a frame 100, a grinding clamping unit 200, a grinding pestle 400, and a grinding adjustment unit 500.
[0026] A geared motor 110 is mounted on the frame 100.
[0027] The grinding clamping unit 200 includes a turntable 210, an annular pressure plate 220, and several fixing screws 230.
[0028] The turntable 210 is coaxially mounted on the rotor of the geared motor 110. Several fixing screws 230 are screwed onto the turntable 210 in a ring array. Several through holes are opened on the ring pressure plate 220, and the ring pressure plate 220 is slidably connected to the fixing screws 230 through the through holes. The mortar 300 is arranged between the ring pressure plate 220 and the turntable 210.
[0029] The grinding adjustment unit 500 includes a lead screw 520, a second guide rod 530, a slider 540, and two support rods 510.
[0030] The support rod 510 is fixed to the upper surface of the frame 100, and the lead screw 520 is arranged in parallel with the second guide rod 530.
[0031] Both ends of the lead screw 520 are rotatably connected to the support rod 510, the slider 540 is threadedly connected to the lead screw 520, and a screw handle 521 is installed at the end of the lead screw 520. The screw handle 521 is integrally provided with anti-slip texture.
[0032] Both ends of the second guide rod 530 are fixedly connected to the support rod 510, and the slider 540 is slidably connected to the second guide rod 530.
[0033] The grinding pestle 400 is arranged parallel to the axis of the geared motor 110, and the grinding pestle 400 is slidably connected to the slider 540.
[0034] Specific Implementation Method Two: Combining Figures 1 to 4 This embodiment describes a grinding pestle 400 comprising a grinding head 410, a first guide rod 420, a compression spring 430, and a pressing handle 440.
[0035] The grinding head 410 and the pressing handle 440 are respectively fixed to both ends of the first guide rod 420.
[0036] The first guide rod 420 is slidably connected to the slider 540, and the compression spring 430 is fitted on the first guide rod 420, with the two ends of the compression spring 430 abutting against the pressing handle 440 and the slider 540 respectively.
[0037] The other components and connections are the same as in Specific Implementation Method 1.
[0038] Specific implementation method three: Combining Figures 1 to 4 In this embodiment, the fixing screw 230 is a double-ended stud.

[0043] Working principle
[0044] Tighten the nut on the fixing screw 230 to clamp the mortar 300 between the annular pressure plate 220 and the turntable 210. Therefore, after starting the reduction motor 110, the mortar 300 can rotate together with the grinding clamping unit 200.
[0045] When the lead screw 520 is turned, the slider 540 moves along the length of the lead screw 520, thereby enabling the pestle 400 to move in the diameter direction of the mortar 300; when the pressing handle 440 is pressed down, the grinding head 410 feeds towards the bottom of the mortar 300; after the pressing handle 440 is released, the grinding head 410 moves away from the bottom of the mortar 300 under the action of the compression spring 430.
[0046] Place the sample into the mortar 300, start the geared motor 110, adjust the position of the slider 540 on the lead screw 520, and press down the pressing handle 440. The sample can then be fully ground between the grinding head 410 and the bottom of the mortar.
[0047] The present invention has been disclosed above with reference to preferred embodiments, but it is not intended to limit the present invention. Any simple modifications, equivalent changes and alterations made by those skilled in the art to the above embodiments without departing from the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
