Description

Technical Field

[0001] This utility model relates to the field of food inspection technology, and in particular to a food inspection grinding device. Background Technology

[0002] Grinding devices are specialized equipment in the field of food inspection technology used to grind solid food samples into small particles or powders for subsequent experiments such as sensory testing, nutritional analysis, and detection of additives and harmful substances. Most of them use motors to drive the grinding blades to pulverize the samples, replacing manual grinding and improving efficiency.

[0003] The pharmaceutical testing grinder disclosed in Chinese Patent Publication No. CN218742314U uses a scraper to scrape off the discharged powder, which facilitates powder discharge. However, according to related technologies and existing technologies, in traditional food grinding equipment, the blades are in a fixed position inside the grinding chamber during use. The sample needs to be repeatedly contacted for a long time to achieve grinding, resulting in slow processing speed. Moreover, some materials are easily not fully ground due to their fixed position, resulting in poor overall uniformity. At the same time, most water-containing food samples tend to adhere to the chamber wall during grinding, which prevents them from contacting the blades to participate in grinding, reducing the overall grinding effect and causing incomplete powder discharge and high residue levels. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a food inspection grinding device.

[0012] Beneficial effects:

[0013] This food testing and grinding device, through the setting of triggering and rotating components, uses first and second ball bearings to force the grinding cylinder to move up and down reciprocally, ensuring that materials of different heights can dynamically contact the rotating blades, thus accelerating the grinding speed and improving the uniformity of grinding.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0025] like Figures 1 to 7As shown, a food testing grinding device includes a base 1, an outer cylinder 2 fixedly mounted on the top of the base 1, a cylinder cover 3 mounted on the top of the outer cylinder 2, a grinding component 4 for rotating and grinding samples mounted at the center of the cylinder cover 3, a grinding cylinder 5 slidably mounted inside the outer cylinder 2, and the grinding cylinder 5 and the outer cylinder 2 are slidably connected by multiple sliding strips 9. The outer cylinder 2 has grooves 10 corresponding to the positions of the multiple sliding strips 9. A spring 7 is provided between the grinding cylinder 5 and the base 1, and a trigger component 6 is provided inside the spring 7. A rotating component 8 is mounted at the center of the base 1 for cooperating with the trigger component 6 to push the grinding cylinder 5 up and down. Multiple positioning blocks 11 are fixedly mounted at the joint between the cylinder cover 3 and the outer cylinder 2, and positioning grooves 12 are provided at the positions of the multiple positioning blocks 11 on the outer cylinder 2. In use, the cylinder cover 3 is opened and the food sample is placed into the grinding cylinder 5. At this time, the weight of the sample will cause the grinding cylinder 5 to compress the spring 7 downwards, and drive the trigger component 6 to move downwards. Subsequently, the grinding cylinder 5 is rotated and ground. Position block 11 aligns with positioning groove 12 and engages cylinder cover 3, ensuring no relative rotation between cylinder cover 3 and outer cylinder 2. At this time, crushing component 4 is activated to crush the sample. During the crushing process, rotating component 8 is activated and, in conjunction with triggering component 6, forces crushing cylinder 5 to move up and down along slide groove 10 under the restriction of slide bar 9. This reciprocating up and down movement causes vertical displacement of the sample, ensuring that samples at different heights can fully contact crushing component 4, accelerating the crushing speed and improving crushing uniformity. At the same time, vibration can dislodge samples adhering to the cylinder wall, allowing them to contact crushing component 4, further improving crushing uniformity and reducing residue on the cylinder wall, facilitating the subsequent complete removal of powder. In addition, the downward movement distance of crushing cylinder 5 is automatically adjusted by the sample volume. Under light load, the amplitude is small, avoiding excessive vibration that could cause powder splashing or blade dry-hitting, while reducing equipment wear and extending equipment life. Under heavy load, the amplitude increases, overcoming the cohesive force between materials through stronger vibration, ensuring thorough crushing.

[0026] like Figure 1 and Figure 3 As shown, the crushing assembly 4 includes a first drive member 41 fixed to the top of the cylinder cover 3. A crushing shaft 42 is fixedly provided at the output end of the first drive member 41. The crushing shaft 42 passes through the cylinder cover 3 and extends into the crushing cylinder 5. Multiple blades 43 are fixedly installed on the axial direction of the crushing shaft 42. When the first drive member 41 is activated, it drives the crushing shaft 42 to rotate the blades 43 and crush the sample.

[0027] like Figure 3 As shown, the triggering component 6 includes a fixing ring 61 fixed to the bottom of the crushing cylinder 5. Multiple first balls 62 are rotatably mounted on the bottom of the fixing ring 61. When crushing, the first balls 62 at the bottom of the fixing ring 61 are triggered by the rotating component 8, which drives the fixing ring 61 and the crushing cylinder 5 to move up and down along the slide groove 10 under the restriction of the slide bar 9, so as to ensure that the blade 43 can cover materials of different heights and improve the crushing uniformity.

[0028] like Figures 3 to 7 As shown, the rotating assembly 8 includes a second driving member 81 fixed to the bottom of the base 1. The output axis of the second driving member 81 passes through the base 1 and is fixedly mounted on a turntable 82. The turntable 82 is rotatably connected to the base 1. Second balls 83 are rotatably mounted on the turntable 82 at positions corresponding to multiple first balls 62. The multiple first balls 62 and multiple second balls 83 are arranged in a circumferential array. In the initial state, the multiple first balls 62 and multiple second balls 83 are staggered, with the bottom of the first balls 62 tangent to the top of the second balls 83. When the sample is placed inside the crushing cylinder 5, the weight of the sample will cause the crushing cylinder 5 to compress the spring 7 downward, causing the fixing ring 61 to move the first balls 62 downward, forming a partial height overlap with the second balls 83. During the crushing process, the second driving member 81 synchronously drives the turntable 82 to rotate, causing the second balls 83 to rotate around the axis, and their positions continuously overlap and stagger with the first balls 62. When they overlap, the second ball bearing 83 pushes the first ball bearing 62, causing the fixed ring 61 and the crushing cylinder 5 to move upward along the slide groove 10 under the restriction of the slide bar 9. When they intersect, the crushing cylinder 5 compresses the spring 7 and moves downward under the action of the sample's gravity, and the first ball bearing 62 once again overlaps with the height of the second ball bearing 83. This reciprocating up-and-down motion causes the sample to have a vertical displacement, ensuring that the blade 43 can cover materials at different heights and improve the uniformity of crushing. At the same time, the vibration can shake off the sample adhering to the cylinder wall, avoiding the accumulation of the sample in dead corners, further improving the uniformity of crushing, and reducing the residue on the cylinder wall, making it easier to completely pour out the powder later. In addition, the downward movement distance of the crushing cylinder 5 is automatically adjusted by the sample amount. Under light load, the amplitude is small, avoiding excessive vibration that could cause powder to splash or blades to strike dry, while reducing equipment wear and extending equipment life. Under heavy load, the amplitude increases, and stronger vibration overcomes the cohesive force between materials, ensuring thorough crushing.

[0029] The work process is as follows:

[0030] S1: As Figure 3 and Figure 6 As shown, when in use, open the cylinder cover 3 and put the food sample into the crushing cylinder 5. At this time, the weight of the sample will cause the crushing cylinder 5 to compress the spring 7 downward, causing the fixing ring 61 to drive the first ball 62 to move down and form a partial height overlap with the second ball 83.

[0031] S2: As Figure 1 and Figure 2 As shown, the positioning block 11 is then aligned with the positioning groove 12 and the cylinder cover 3 is fastened to ensure that the cylinder cover 3 and the outer cylinder 2 do not rotate relative to each other. At this time, the first driving component 41 is activated, driving the crushing shaft 42 to rotate the blade 43 to crush the sample.

[0032] S3: As Figure 6 and Figure 7As shown, during the crushing process, the second driving component 81 synchronously drives the turntable 82 to rotate, causing the second ball 83 to rotate around the axis, and its position continuously overlaps and intersects with the first ball 62.

[0033] S4: As Figure 7 As shown, when they overlap, the second ball 83 pushes the first ball 62, causing the fixed ring 61 and the crushing cylinder 5 to move upward along the slide groove 10 under the restriction of the slide bar 9.

[0034] S5: As Figure 6 As shown, during the alternation, the crushing cylinder 5 compresses the spring 7 and moves downward under the action of the sample's gravity, and the first ball 62 once again overlaps with the height of the second ball 83.

[0035] S6: As Figure 3 As shown, this reciprocating up-and-down motion causes the sample to be vertically displaced, ensuring that the blade 43 can cover materials at different heights, improving the uniformity of crushing. At the same time, the vibration can shake off the sample adhering to the cylinder wall, avoiding the accumulation of sample in dead corners, further improving the uniformity of crushing, and reducing the residue on the cylinder wall, making it easier to completely pour out the powder later.

[0036] S7: As Figure 3 As shown, in addition, the downward movement distance of the crushing cylinder 5 is automatically adjusted by the sample amount. Under light load, the amplitude is small to avoid excessive vibration that could cause powder to splash or blades to strike dry, while reducing equipment wear and extending equipment life. Under heavy load, the amplitude increases, and stronger vibration can overcome the cohesive force between materials to ensure thorough crushing.

[0037] The first driving component 41 and the second driving component 81 in this application are known technologies in this field, therefore their specific structures and working principles are not described in detail.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
