Description

Technical Field

[0001] The invention belongs to the technical field of food production equipment, and particularly relates to a functional food grinding device. Background Art

[0002] With the continuous expansion of the functional food market, the demand for crushing and grinding plant seeds, medicinal and edible ingredients, and nuts is growing. Traditional food grinding equipment often uses blade or roller structures, shearing or crushing the ingredients with high-speed rotating blades or rollers to achieve the desired grinding effect. However, in actual use, these traditional grinding equipment still have many shortcomings.

[0003] On the one hand, most existing equipment's grinding mechanisms only have a single rotary crushing function. When raw materials have uneven particle sizes or localized accumulation, the grinding components are prone to jamming or slipping, affecting the equipment's continuous and stable operation. On the other hand, when dealing with some hard and elastic raw materials, a single grinding method often fails to effectively break down the raw material's internal structure, resulting in suboptimal grinding results, low product fineness, and poor uniformity, which in turn affects subsequent processing and product quality. Furthermore, some equipment lacks adaptive mechanisms to cope with varying loads, resulting in poor maneuverability and prone to equipment damage under high loads. Summary of the Invention

[0004] In response to the problems existing in the prior art, the purpose of the present invention is to provide a functional food grinding device that can perform both rolling and periodic percussion grinding, so as to improve the grinding efficiency and the ability to adapt to the processing of complex raw materials, while avoiding jamming and slipping problems, and improving the stability and intelligence level of the overall grinding process.

[0005] To achieve the above object, the present invention provides the following technical solutions: A functional food grinding device includes a body and a roller limiting shaft. A top cover is installed on the top of the body, and a grinding motor is installed at the center of the upper surface of the top cover. A rotor shaft is provided at one end of the grinding motor, and a buffer plate and a roller plate are nested and fixed in sequence at the bottom of the rotor shaft. One end of the roller limiting shaft and the roller plate are movably connected by a rotating shaft, and a grinding roller is nested at the other end of the roller limiting shaft. An anti-slip lifter is installed between the roller limiting shaft and the buffer plate, and the anti-slip lifter is used to lift the roller limiting shaft to prevent slipping.

[0006] Furthermore, the anti-slip lifter includes a lifter shaft, and a spring limiting chassis, a return spring and a spring limiting top plate are sequentially nested and installed on the outer side of the lifter shaft, and a nut is installed on the side of the lifter shaft corresponding to the spring limiting chassis through a threaded engagement, and a nut is also installed on the side of the lifter shaft corresponding to the spring limiting top plate through a threaded engagement.

[0007] Furthermore, the lifter shaft and the roller limiting shaft are movably connected via a rotating shaft, and the spring limiting top plate and the buffer plate are movably connected via a rotating shaft.

[0008] Furthermore, the grinding roller and the roller limiting shaft are movably connected through bearings, and an elliptical knocking plate is fixed to one end of the grinding roller. The front view of the elliptical knocking plate is elliptical, and the elliptical knocking plate is used for the periodic lifting and lowering of the grinding roller.

[0009] Furthermore, a spherical striking head is provided at the tail end of the grinding roller, and a protrusion is provided on the surface of the spherical striking head. A table-shaped grinding seat is placed inside the body, and a protrusion is also provided on the upper surface of the table-shaped grinding seat.

[0010] Furthermore, the table-shaped grinding seat divides the internal space of the fuselage into a grinding chamber and a feeding chamber, and a grinding seat support rod is welded to the inner wall of the fuselage corresponding to the bottom of the table-shaped grinding seat, and a discharge port is opened on one side of the bottom of the fuselage.

[0011] Furthermore, a feed port is provided on the upper surface of the top cover.

[0012] Furthermore, a discharge rod is provided at the bottom center of the table-shaped grinding seat, and a handle is installed after the tail end of the discharge rod passes through the bottom of the fuselage, and a supporting leg is provided at the bottom of the fuselage.

[0013] Compared with the prior art, the present invention has the following beneficial effects: By setting up an anti-skid lifter, the grinding roller can be automatically lifted when encountering material accumulation or overload resistance, and return to its original position with the help of the elastic action of the return spring, thus effectively preventing the grinding roller from getting stuck or idling and slipping, improving the maneuverability and operating stability of the device, and solving the technical problem that traditional grinding devices are prone to malfunction when the material is uneven or the load fluctuates; By setting the elliptical knocking disc at one end of the grinding roller, the grinding roller can be periodically lifted and lowered during the grinding process under the rotation of the roller disc, generating a continuous knocking action. The raw materials are repeatedly knocked while being rolled, effectively improving the crushing effect of hard or fibrous raw materials, and solving the problem of poor grinding effect of existing grinding devices on tightly structured or elastic raw materials. By setting a spherical striking head at the tail end of the grinding roller and a corresponding raised structure on the surface of the table-type grinding seat, the two form multi-angle contact points during movement, thereby enhancing local pressure and striking force, further improving the grinding effect, and increasing the uniformity of material crushing, thus solving the problems of uneven grinding particle size and low fineness of traditional devices.

[0018] like Figure 2 and Figure 3 As shown, the anti-slip lifter includes a lifter shaft 181; a spring limiting chassis 182, a return spring 183 and a spring limiting top plate 184 are nested and installed on the outer side of the lifter shaft 181 in sequence; the spring limiting chassis 182 is used to limit the lower stroke position of the return spring 183 to prevent sliding and dislocation; the spring limiting top plate 184 is used to limit the upper stroke space of the return spring 183 to ensure that the elastic force always acts on the grinding assembly; a nut is installed on the side of the lifter shaft 181 corresponding to the spring limiting chassis 182 through a threaded engagement, which is used to adjust the position of the limiting chassis to adapt to different clamping force requirements; a nut is also installed on the side of the lifter shaft 181 corresponding to the spring limiting top plate 184 through a threaded engagement, which is used to lock the position structure of the entire anti-slip assembly, thereby ensuring that the lifting stroke of the grinding roller 161 is stable and has anti-slip ability.

[0019] like Figure 2 and Figure 3 As shown, the lifter shaft 181 and the roller limit shaft 162 are movably connected by a rotating shaft, which is used to realize the upward displacement action of the grinding roller 161 when encountering resistance; the spring limit top plate 184 and the buffer plate 105 are movably connected by a rotating shaft, thereby buffering the up and down impact forces generated by the knocking grinding during system operation, enhancing the equipment operation stability, improving the response speed of the reset spring 183, and cooperating with the rotation of the roller plate 106 to maintain the continuous movement of the grinding roller 161.

[0020] like Figure 3-Figure 5 As shown, the grinding roller 161 and the roller limiting shaft 162 are movably connected by bearings. The setting of the bearings can effectively reduce the friction generated during the grinding process and improve the rotation flexibility; an elliptical knocking disk 163 is fixed to one end of the grinding roller 161, and the elliptical knocking disk 163 is elliptical in the front view. The setting of the elliptical structure can realize periodic up and down vibration, so that the grinding roller 161 is continuously lifted and fallen during the rolling process, thereby forming a knocking force to simulate the hammering effect; the elliptical knocking disk 163 is used in conjunction with the upper surface of the table-type grinding seat 107, so that the raw materials can obtain periodic impacts while being crushed, thereby improving the structural crushing efficiency of fiber raw materials, nut materials, etc., and overcoming the technical defects of incomplete grinding of traditional equipment.

[0021] like Figure 2-Figure 4As shown, a spherical striking head 164 is provided at the tail end of the grinding roller 161; the surface of the spherical striking head 164 is provided with a raised structure, which can increase the contact pressure during the grinding process and at the same time play the role of multi-angle and point hammering; a table-type grinding seat 107 is placed inside the fuselage 101, and the upper surface of the table-type grinding seat 107 is also provided with a raised structure. The raised structure works together with the spherical striking head 164 to provide different forms of crushing and striking paths at different grinding stages, thereby enhancing the crushing depth of the device on the raw material tissue and effectively improving the grinding fineness and uniformity.

[0022] like Figure 2-Figure 5 As shown, the table-type grinding seat 107 divides the internal space of the body 101 into a grinding chamber 111 and a discharge chamber 112; the grinding chamber 111 is used to perform multi-form grinding operations on the incoming raw materials; the discharge chamber 112 is used to guide the ground fine powder to the discharge end; a grinding seat support rod 114 is welded to the inner wall of the body 101 corresponding to the bottom of the table-type grinding seat 107, which is used to support the table-type grinding seat 107 and prevent the grinding seat from shifting or tilting under the action of high-frequency vibration and high pressure; a discharge port 113 is provided on one side of the bottom of the body 101 for discharging the ground material to meet the process requirements of continuous processing of functional foods.

[0023] like Figure 4 and Figure 5 As shown, a feed port 121 is provided on the upper surface of the top cover 102; the feed port 121 is located directly below the center of the grinding motor 103, and the raw materials fall directly into the grinding chamber 111 through the feed port 121. The feeding path is smooth, which facilitates the integration of the automated processing system and effectively improves work efficiency.

[0024] like Figure 4 and Figure 5 As shown, a discharge rod 171 is provided at the bottom center of the table-type grinding seat 107, and a handle is installed after the tail end of the discharge rod 171 passes through the bottom of the fuselage 101; the handle is used to manually control the up and down movement of the discharge rod 171 to realize the cleaning operation of the remaining material or stuck material in the grinding chamber 111; the bottom of the fuselage 101 is provided with a support leg 104, which is integrally formed with the base structure or screwed together, which can provide structural stability of the grinding device and ensure that the equipment does not deviate or resonate during continuous operation under high load. Example

[0025] See Figure 1-Figure 3As shown, a functional food grinding device with anti-stuck and anti-skid functions includes an anti-skid lifter, a buffer plate 105, a roller limiting shaft 162 and a grinding roller 161; the anti-skid lifter is composed of a lifter shaft 181, a stainless steel return spring 183 (model is Φ6×60mm), an aluminum alloy spring limiting chassis 182 and a top plate 184, and the lifter shaft 181 is made of high-strength 45# steel and is connected to the lower end of the roller limiting shaft 162 through a rotating shaft to realize vertical force transmission; when the raw material is accumulated or blocked on the surface of the table-type grinding seat 107, the grinding roller 161 is forced to lift under the action of rotational inertia, the return spring 183 is compressed, and then the elastic force is released to reset the grinding roller 161, completing an anti-resistance sliding process to avoid slipping or jamming due to overload. Example

[0026] See Figure 3-Figure 5 As shown, a grinding structure that achieves periodic knocking through an elliptical knocking disk 163, an elliptical knocking disk 163 made of wear-resistant carbon steel is set at the end of the grinding roller 161, the major axis and minor axis dimensions are 40mm and 30mm respectively, and the elliptical disk is fixedly connected to the end of the roller limit shaft 162; when the grinding motor 103 is running, the rotor shaft 131 drives the buffer disk 105, the roller disk 106 and the grinding roller 161 to rotate in turn; due to the asymmetric structure of the elliptical disk, the grinding roller 161 generates periodic up and down vibrations, thereby achieving raw material knocking; this knocking action superimposes the impact load on the basis of crushing, which significantly enhances the crushing efficiency of fiber and hard shell materials. Example

[0027] See Figure 2-Figure 4 As shown, a structure is provided with a spherical striking head 164 and a raised table-type grinding seat 107. The spherical striking head 164 adopts a high-manganese steel sphere with a diameter of 20 mm, and a plurality of hemispherical protrusions (each protrusion has a diameter of 2 mm) are processed on the surface to increase the unit contact pressure; the table-type grinding seat 107 is processed with a regular protrusion structure (1 mm high, 3 mm wide), which constitutes a multi-angle striking path during the rolling and falling process of the ball head, thereby realizing local deep crushing; this combination enables the grinding roller 161 to generate a concentrated hammering force on the basis of the original crushing force during the striking process, thereby improving the thoroughness of the raw material crushing and the uniformity of the powder. Example

[0028] See Figure 2-Figure 5As shown, a grinding chamber system with an upper and lower separated structure, the table-type grinding seat 107 is made of cast aluminum material with a thickness of 6mm, and a discharge rod 171 with a diameter of Φ12mm is set at the center of its bottom, and an external handle is connected through its tail for manual control to open; the top of the table-type grinding seat 107 is a spatial grinding chamber 111 for performing multi-dimensional grinding operations, and the bottom is a discharge chamber 112, which is connected to the discharge port 113 on the bottom side of the fuselage 101 to ensure that the material falls directly after grinding without back-piling or clogging; this structure, combined with the grinding seat support rod 114 welded on the inner wall, can effectively bear the knocking load and keep the device vertically stable.

[0029] The working principle of the present invention is: When in use, first, the grinding motor 103 is powered on, and the raw material is fed into the grinding chamber 111 of the machine body 101 through the feed port 121. Then, the power of the grinding motor 103 is turned on, and the grinding motor 103 starts to work. The rotor shaft 131 drives the buffer plate 105 and the roller plate 106 to rotate. The roller plate 106 drives the roller limiting shaft 162 and the grinding roller 161 to roll on the upper surface of the table-shaped grinding seat 107. The grinding roller 161 rolls and grinds the raw material that has landed on the upper surface of the table-shaped grinding seat 107. When the raw materials are large or accumulated, blocking the grinding roller 161 from rolling forward, the rolling grinding roller 161 is lifted upward under the action of resistance, squeezing the return spring 183 of the anti-slip lifter, thereby preventing the grinding roller 161 from getting stuck and slipping, thereby improving the maneuverability of the grinder. The oval knocking plate 163 at the end of the rolling grinding roller 161 rolls on the upper surface of the table-shaped grinding seat 107, periodically driving the grinding roller 161 to rise and fall. Figure 4 At this time, one end of the long axis of the elliptical knocking plate 163 contacts the upper surface of the table-type grinding seat 107, and the grinding roller 161 is in the lifting energy storage state. Figure 5 At this time, one end of the short axis of the elliptical knocking plate 163 contacts the upper surface of the table-type grinding seat 107, and the grinding roller 161 is in a falling hammering state, so that the grinding roller 161 repeatedly knocks the raw materials on the upper surface of the table-type grinding seat 107, realizing diversified grinding of raw materials and improving grinding efficiency.

[0030] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
