Description

Technical Field

[0001] This utility model relates to the field of pulverizing device technology, specifically a high-efficiency pulverizing device for food testing. Background Technology

[0002] Food safety is a global issue. Food safety problems mainly include the following aspects: chemical hazards, biotoxins, microbial hazards, food adulteration, and the safety of genetic engineering. In my country, microbial contamination, pesticide residues, pollution of water sources such as rivers, lakes, and coastal areas, as well as the illegal addition of hormones and drugs are significant factors contributing to food insecurity. Therefore, to ensure public health, food safety testing is necessary.

[0003] Chinese utility model CN210571631U discloses a food crushing and sampling machine for food testing, which features a crushing structure. The principle is that an extrusion plate is installed inside the feed hopper above the crusher. When crushing is required, the food generally needs to be pre-crushed to improve the crushing effect and increase the crushing efficiency. Simply add the food into the feed hopper, turn the handle to drive the threaded rod to rotate, thereby driving the extrusion plate to move and crush the food inside the feed hopper. The crushed food then enters the crushing chamber through the bottom screen for further crushing.

[0004] However, in existing devices, when the extrusion plate is driven by a threaded rod, the extrusion plate moves inside the feed hopper. Pushing food to one side may cause it to fall onto the other side of the extrusion plate. This accumulation on the other side can affect the rotation of the threaded rod, potentially causing it to rust and hindering its operation. Therefore, to address the aforementioned problems, an extrusion plate structure was designed that is unaffected by food accumulation. Utility Model Content

[0031] Food safety is a global issue, with serious food safety incidents occurring frequently internationally, causing enormous economic losses. Food safety issues mainly include the following aspects: chemical hazards, biotoxins, microbial hazards, food adulteration, and the safety of genetic engineering. In my country, microbial contamination, pesticide residues, pollution of water sources such as rivers, lakes, and coastal areas, as well as the illegal addition of hormones and drugs are significant factors contributing to food insecurity. Therefore, to ensure public health, food safety testing is necessary.

[0032] In related technologies, a pressing plate is installed inside the feed hopper above the grinder. To improve grinding efficiency, food typically undergoes pre-crushing. This is achieved by adding food to the feed hopper, rotating the handle to drive the threaded rod, which in turn moves the pressing plate within the hopper, crushing the food. The crushed food then passes through a screen at the bottom and enters the grinding chamber for further pulverization. However, in existing devices, when the threaded rod drives the pressing plate, the plate moves within the feed hopper. Pushing food to one side may cause it to fall onto the other side of the pressing plate. This accumulation on the other side can affect the rotation of the threaded rod, potentially leading to rust and hindering its operation.

[0033] To address some of the problems in related technologies, this application provides a high-efficiency pulverizing device for food testing. When food needs to be pulverized, the food is first placed into the pulverizing chamber 12 through the inlet at the top, falling onto the screen 13. Then, the pulverizing chamber 11 is connected to an external power source to drive the internal pulverizing roller to rotate. The motor 23 is then started, driving the threaded rod 22 to rotate. As the threaded rod 22 rotates, it moves the slider 24 away and simultaneously drives the connecting rod 25 to rotate, pushing the top plate 26 downward. This causes the top plate 26 to push the upright rod 27 downward until the extrusion plate 28 extrudes the food, causing it to break. Then, the motor 23 drives the threaded rod 22 to rotate, causing the slider 24 to move closer. Through the connecting rod 25, the top plate 26 and the upright rod 27 move upward, simultaneously pulling the extrusion plate 28 upward. The motor 23 controls the up-and-down movement of the extrusion plate 28 to crush the food inside the pulverizing chamber 12. The crushed food then falls through the screen 13 into the pulverizing chamber 11 for further pulverization. Finally, the pulverized powder is taken out for testing to determine if the food is qualified. During the extrusion process, a lot of food fragments will accumulate on the screen 13, which is not conducive to screening. At this time, the crossbar 32 can be rotated to drive the lever 33 to rotate, so that one end of the lever 33 can strike the screen 13, causing the screen 13 to move upward. Due to its own gravity, it moves downward and is blocked by the baffle 31, which can prevent the screen 13 from clogging and improve the screening effect.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Combination Figures 1-4 This application provides a high-efficiency pulverizing device for food testing, comprising: a pulverizing chamber 11 with a feeding chamber 12 at its top and internally connected, wherein a pulverizing roller is provided inside the pulverizing chamber 11 for pulverizing food; a screen 13 disposed inside the feeding chamber 12; and a lifting assembly 2 disposed on the feeding chamber 12, the lifting assembly 2 comprising: a protruding plate 21 fixedly disposed on the top of the feeding chamber 12; a threaded rod 22 disposed on the protruding plate 21 and rotatably connected to the protruding plate 21; and a motor 23. The output shaft is connected to the threaded rod 22 and placed on one side of the convex plate 21; the slider 24 is penetrated by the threaded rod 22 and threadedly connected to the threaded rod 22; the bottom end of the connecting rod 25 is rotatably connected to the top of the slider 24; the top plate 26 is disposed at the top end of the connecting rod 25 and rotatably connected to the connecting rod 25; the upright rod 27 is disposed at the bottom of the top plate 26 and its bottom end is inserted into the interior of the feed hopper 12; the extrusion plate 28 is disposed inside the feed hopper 12 and connected to the bottom end of the upright rod 27.

[0036] Specifically, the crushing chamber 11 is equipped with a crushing roller with blades on its surface, which is driven to rotate by a drive motor. This roller can crush food fragments that fall into the crushing chamber. The bottom surface of the slider 24 is in contact with the inner wall of the feed chamber 12, which can restrict the rotation of the slider 24. The threaded rod 22 has a bidirectional thread on its surface, which can control the two sliders 24 to move in opposite directions.

[0037] When food needs to be pulverized, the food is first placed into the feed chamber 12 through the inlet at the top and falls onto the screen 13. Then, the pulverizing chamber 11 is connected to an external power source to drive the internal pulverizing rollers to rotate. The motor 23 is then started to drive the threaded rod 22 to rotate. As the threaded rod 22 rotates, it moves the slider 24 away and simultaneously drives the connecting rod 25 to rotate, pushing the top plate 26 downward. This causes the top plate 26 to push the upright rod 27 downward until the extrusion plate 28 extrudes the food, causing it to break. Then, the motor 23 drives the threaded rod 22 to rotate, causing the slider 24 to move closer. Through the connecting rod 25, the top plate 26 and the upright rod 27 move upward, simultaneously pulling the extrusion plate 28 upward. The motor 23 controls the up-and-down movement of the extrusion plate 28 to crush the food inside the feed chamber 12. The crushed food then falls through the screen 13 into the pulverizing chamber 11 for further pulverization. Finally, the pulverized powder is taken out for inspection to determine if the food is up to standard.

[0038] In some embodiments, the outer wall of the extrusion plate 28 is in contact with the inner wall of the feed hopper 12.

[0039] The close-fitting design allows for maximum compression of all food items on the screen 13, crushing them.

[0040] In some embodiments, the lifting assembly 2 further includes: a plurality of protrusions 29, all disposed at the bottom of the extrusion plate 28.

[0041] When in use, the triangular design at the bottom of the convex strip 29 helps to crush food more effectively when it is squeezed.

[0042] In some embodiments, a vibration assembly 3 is provided inside the feed hopper 12. The vibration assembly 3 includes: baffles 31 symmetrically arranged on the inner sidewall of the feed hopper 12; a crossbar 32 with one end inserted into the interior of the feed hopper 12 and rotatably connected to the feed hopper 12; and a lever 33 disposed on the outer sidewall of the crossbar 32.

[0043] During use, many food fragments will accumulate on the screen 13 during the squeezing process, which is not conducive to screening. At this time, the crossbar 32 can be rotated to drive the lever 33 to rotate, so that one end of the lever 33 can strike the screen 13, causing the screen 13 to move upward. Due to its own gravity, it moves downward and is blocked by the baffle 31, which can prevent the screen 13 from clogging and improve the screening effect.

[0044] In some embodiments, the lever 33 is provided with multiple sets.

[0045] When in use, the design of multiple levers 33 allows for a wider range of tapping on the bottom of the screen 13, resulting in a better vibration effect.

[0046] In some embodiments, the vibration assembly 3 further includes a handle 34 disposed at one end of the lever 33.

[0047] The handle 34 is designed for easy gripping and makes turning the crossbar 32 easier.

[0048] In some embodiments, the vibration assembly 3 further includes: multiple rods 35, each having its top end passing through the baffle 31 and connected to the screen 13; and multiple baffles 36, each located at the bottom of the rods 35.

[0049] When in use, the design of the rod 35 and the baffle 36 allows the screen 13 to move upward stably without tilting, and the design of the baffle 36 can prevent the rod 35 from separating from the baffle 31.

[0050] In some embodiments, the vibration assembly 3 further includes a rubber ball 37 disposed at one end of the lever 33.

[0051] The design of the rubber ball 37 during use allows it to better protect the screen 13 and reduce scratches when in contact with it.
