Description

Technical Field

[0001] The present invention relates to a grinding mechanism, in particular to a grinding mechanism for finely grinding food. Background Art

[0002] The grinding mechanism for finely grinding food is a key equipment in the field of food processing. It generally includes a grinding bowl and a grinding roller, and uses the rolling friction of the grinding roller in the grinding bowl to grind the material into powder. As shown in a patent for a food fermentation and grinding device (publication number CN215029525U), it includes a material box, the bottom of which is connected to a motor by bolts, the output end of the motor is welded with a transmission shaft, the upper surface of the transmission shaft is rotatably connected to a sealing box, the surface of the sealing box is welded to the inner wall of the material box through a connecting rod, a grinding mechanism is provided inside the sealing box, and a juice filtering mechanism is provided on the surface of the transmission shaft. By pouring the picked grapes into the upper part of the material box and rotating the two grinding rollers, the grapes are ground and crushed, thereby achieving efficient grinding and separation of the grapes, so that the grape juice is very uniform during the grinding and pressing process, and the impurities in the grape juice can be better removed through fine filtration of the filter cloth, so that the taste after fermentation is improved. However, in such devices, the internal grinding mechanism is generally fixedly connected to the material box, so it is very inconvenient when it needs to be cleaned. Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a grinding mechanism for finely grinding food, which adopts a horizontal combination structure with an outer cylinder and an inner roller that rotate independently to achieve an efficient grinding effect under automatic material mixing. At the same time, the overall detachable combination connection method can also make it easier to clean after the grinding is completed.

[0004] The present invention provides the following technical solutions: A grinding mechanism for finely grinding food, comprising an outer frame, an outer cylinder mounted on the outer frame, an inner roller detachably assembled and mounted in the outer cylinder, and an outer cover detachably connected to a port of the outer cylinder. In the grinding working state, the outer cylinder is horizontally mounted, and its rotation axis is horizontally distributed. A plate frame is mounted on one end of the inner roller close to the bottom of the outer cylinder, and the outer cover is limited at the end of the inner roller away from the bottom of the outer cylinder, and the outer cover and the plate frame are both positioned on the outer frame. The inner roller comprises a grinding outer roller mounted in a transfer manner and a central shaft, and the central shaft is positioned between the plate frame and the outer cover, and the grinding outer roller is sleeved on the outside of the central shaft and driven to rotate by a driving member in the central shaft, and the rotation axis of the grinding outer roller is parallel to the rotation axis of the outer cylinder, and the grinding outer roller is roll-pressed and mounted on the bottom layer of the outer cylinder body, and the grinding outer roller and the outer cylinder rotate in opposite directions. When grinding operations are required, first place the plate frame together with the inner roller in the outer cylinder, then pour the material to be ground into the outer cylinder, then close the outer cover, drive the outer cylinder and the grinding outer roller to rotate in the opposite direction, and the material can be driven by the outer cylinder to rotate and stir in the cylinder, while the material that falls to the bottom layer can be ground when passing between the grinding outer roller and the outer cylinder. The horizontal combination mode of two-way independent rotation of the outer cylinder and the grinding outer roller can not only ensure that the material falls freely when it rotates to the top layer with the outer cylinder, but also collides and crushes when falling, and the material that falls between the outer cylinder and the grinding outer roller can be extruded and ground when the outer cylinder and the grinding outer roller rotate, so the grinding fluid is more efficient and reduces the probability of the ground powder material adhering to the cylinder wall. At the same time, the detachable combination connection mode can also make it easier to clean after the grinding is completed.

[0005] Preferably, in the grinding working state, the plate frame is fitted to the bottom of the outer cylinder, and a group of positioning rods passing through the center of the bottom of the outer cylinder are also provided in the center. The positioning rods are installed on the outer frame by inserting and positioning the pins. After the pins are inserted and positioned on the positioning rods and the outer frame, the positioning of the outer frame, the positioning rods and the plate frame can be achieved. At this time, the plate frame and the outer cover position the inner roller, and when the outer cylinder rotates, the inner roller can move independently relative to the outer cylinder, and when disassembling, only the pins need to be removed, which is more convenient.

[0006] Preferably, two groups of triangular oblique blocks are provided at each end of the central axis, and two groups of mounting grooves are opened on the side surfaces of the outer cover and the plate frame respectively, and triangular pressure blocks are installed in the mounting grooves, and the top ends of the triangular pressure blocks are connected to the guide holes of the corresponding outer cover and the plate frame through guide shafts, and the bottoms of the guide holes are also provided with a group of compression springs for pressing against the end ends of the guide shafts. When the triangular oblique blocks are placed in the mounting grooves, the inclined surfaces of the triangular oblique blocks abut against the inclined surfaces of the triangular pressure blocks, and when the grinding gap between the grinding outer roller and the outer cylinder forms accumulated material, the triangular oblique blocks press against the compression springs through the triangular pressure blocks and the guide shafts to expand the gap between the grinding outer roller and the outer cylinder. The elastic pressing not only avoids jamming, but also makes the connection and installation more convenient and more flexible.

[0007] Preferably, a group of drive holes are also opened in the axial direction at the center of the central shaft, and the driving member includes a rotating shaft installed in the drive hole, multiple groups of outer gear rings installed outside the rotating shaft, inner gear rings arranged in the grinding outer roller and corresponding to the outer gear rings one by one, and a transition wheel installed in the central shaft and meshingly connected with the outer gear rings and the inner gear rings. Therefore, when the driving rotating shaft rotates, the multiple groups of outer gear rings can be rotated synchronously, and then the grinding outer roller is driven to rotate through the transition wheel. At the same time, the rotation of the grinding outer roller will not affect the fine adjustment of the position of the grinding outer roller relative to the plate frame and the outer cover, so as to adapt to the adjustment of the grinding gap between the grinding outer roller and the outer cylinder, and has better flexibility.

[0008] Preferably, the driving member further includes a rotary motor for driving the rotary shaft to rotate, and the rotary motor is installed in the central shaft.

[0009] Preferably, an outer gear ring is provided outside the outer cylinder, and an outer gear is installed on the outer frame. The outer gear is driven to rotate by the outer motor and is meshed with the outer gear ring. A corner of the outer frame is connected to a corner motor, and drives the grinding mechanism to rotate by the corner motor. At this point, automatic grinding switching can be achieved through the outer motor and the corner motor. In the grinding working state, the corner motor drives the outer cylinder to be in a horizontal state, and after the installation is completed, the outer motor can drive the outer cylinder to achieve automatic rotation operation. In the unloading state after grinding, after removing the outer cover, the corner motor can be driven to rotate 90°, so that the port of the outer cylinder can be tilted downward. At the same time, when the inner roller is not restricted at the bottom, it can also be tilted out to facilitate subsequent cleaning operations.

[0010] Preferably, the end of the outer frame is provided with a pressure strip driven to rotate by a pressing motor, and the outer side of the outer cover is also provided with a pressing groove that cooperates with the pressure strip to limit the position. When the pressure strip is rotated into the pressing groove, the positioning between the outer cover and the outer frame can be achieved, and when unloading is required, it is only necessary to drive the pressure strip to rotate so that the pressure strip is disengaged from the pressing groove and rotated to a horizontal position, which facilitates the separation of the pressure cover from the outer frame.

[0011] Preferably, the top and bottom of the outer cover are further provided with arc blocks that embrace the outside of the outer cylinder, and the arc blocks located on the bottom side of the outer cover are in contact with the outer frame, thereby improving the stability of the outer cover relative to the outer cylinder and the outer frame when working.

[0012] Preferably, the arc block and the outer cylinder are in contact with each other via balls, so that when the outer cylinder rotates, rolling friction is generated between the arc block and the outer cylinder, thereby reducing the influence of friction.

[0013] Preferably, the outer cover is further provided with a group of scrapers resting against the top layer of the outer cylinder body, and the scrapers are used to scrape off the abrasives adhering to the cylinder wall of the outer cylinder when the outer cylinder rotates.

[0014] The beneficial effects of the present invention are as follows: the present invention provides a grinding mechanism for finely grinding food, which adopts a horizontal combined structure in which the outer cylinder and the inner roller rotate independently to achieve a high-efficiency grinding effect under automatic material leveling. At the same time, the overall detachable combined connection mode can also make it easier to clean after the grinding is completed. When the grinding operation is required, the plate frame together with the inner roller is first placed in the outer cylinder, and then the material to be ground is poured into the outer cylinder, and then the outer cover is closed, and the outer cylinder and the grinding outer roller are driven to rotate in opposite directions, that is, if the outer cylinder rotates clockwise, the outer roller rotates counterclockwise, and the material can be removed from the outer cylinder. The drum drives the rotation and stirring inside the drum, and the material falling to the bottom can be ground when passing between the grinding outer roller and the outer drum. The horizontal combination mode of the outer drum and the grinding outer roller with two-way independent rotation can not only ensure that the material falls freely when it rotates with the outer drum to the top layer, but also collides and crushes when falling. The material falling between the outer drum and the grinding outer roller can be extruded and ground when the outer drum and the grinding outer roller rotate. Therefore, the grinding fluid is more efficient and the probability of the ground powder material adhering to the drum wall is reduced. At the same time, the detachable combination connection mode can also make it more convenient to clean after the grinding is completed. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Example 1 like Figure 1-5 As shown, a grinding mechanism for finely grinding food, in this embodiment, includes an outer frame 1, an outer cylinder 2 adapted to be mounted on the outer frame 1, an inner roller 3 detachably assembled and mounted in the outer cylinder 2, and an outer cover 4 detachably connected to the port of the outer cylinder 2. In the grinding working state, the outer cylinder 2 is horizontally mounted, with its rotation axis 37 line being horizontally distributed. A plate frame 5 is mounted on one end of the inner roller 3 close to the bottom of the outer cylinder 2, and the outer cover 4 is limited to the end of the inner roller 3 away from the bottom of the outer cylinder 2, and the outer cover 4 and The plate frame 5 is positioned on the outer frame 1. The inner roller 3 includes a grinding outer roller 31 and a central shaft 32 that are installed in a transfer manner. The central shaft 32 is positioned and installed between the plate frame 5 and the outer cover 4. The grinding outer roller 31 is sleeved on the outside of the central shaft 32 and is driven to rotate by a driving member in the central shaft 32. The rotation axis 37 of the grinding outer roller 31 is parallel to the rotation axis 37 of the outer cylinder 2. The grinding outer roller 31 is rolled and installed on the bottom layer of the outer cylinder 2. The grinding outer roller 31 and the outer cylinder 2 rotate in opposite directions. When grinding operation is required, first place the plate frame 5 together with the inner roller 3 in the outer cylinder 2, then pour the material to be ground into the outer cylinder 2, then close the outer cover 4, drive the outer cylinder 2 and the grinding outer roller 31 to rotate in the opposite direction, at this time the material can be driven by the outer cylinder 2 to rotate and stir in the cylinder, and at the same time the material falling to the bottom can be ground when passing between the grinding outer roller 31 and the outer cylinder 2. The horizontal combination mode of bidirectional independent rotation of the outer cylinder 2 and the grinding outer roller 31 can not only ensure that the material falls freely when it rotates to the top layer with the outer cylinder 2, but also collides and crushes when falling, and the material falling between the outer cylinder 2 and the grinding outer roller 31 can be extruded and ground when the outer cylinder 2 and the grinding outer roller 31 rotate, so the grinding liquid is more efficient, and the probability of the ground powder material adhering to the cylinder wall is reduced. At the same time, the detachable combination connection mode can also make it easier to clean after the grinding is completed.

[0017] In the grinding working state, the plate frame 5 is fitted to the bottom of the outer cylinder 2, and a group of positioning rods 6 passing through the center of the bottom of the outer cylinder 2 is also provided in the center. The positioning rods 6 are installed on the outer frame 1 through the insertion of the pin 7. After the pin 7 is inserted and positioned on the positioning rods 6 and the outer frame 1, the positioning of the outer frame 1, the positioning rods 6 and the plate frame 5 can be achieved. At this time, the plate frame 5 and the outer cover 4 position the inner roller 3, and when the outer cylinder 2 rotates, the inner roller 3 can move independently relative to the outer cylinder 2, and when disassembling, it is only necessary to remove the pin 7, which is more convenient.

[0018] Two groups of triangular oblique blocks 33 are provided at each end of the central shaft 32, and two groups of mounting grooves are opened on the side surfaces of the outer cover 4 and the plate frame 5. Triangular pressure blocks 34 are installed in the mounting grooves. The top ends of the triangular pressure blocks 34 are guided and connected to the guide holes of the corresponding outer cover 4 and the plate frame 5 through guide shafts 35. The bottom of the guide holes is also provided with a group of compression springs 36 for pressing against the ends of the guide shafts 35. When the triangular oblique blocks 33 are placed in the mounting grooves, the inclined surfaces of the triangular oblique blocks 33 abut against the inclined surfaces of the triangular pressure blocks 34, and when the grinding gap between the grinding outer roller 31 and the outer cylinder 2 forms accumulated material, the triangular oblique blocks 33 press the compression springs 36 through the triangular pressure blocks 34 and the guide shafts 35 to expand the gap between the grinding outer roller 31 and the outer cylinder 2. The elastic pressing not only avoids jamming, but also makes the connection and installation more convenient and more flexible.

[0019] A group of drive holes are also opened in the axial direction at the center of the central shaft 32, and the drive parts include a rotating shaft 37 installed in the drive hole, multiple groups of outer gear rings 39 installed outside the rotating shaft 37, an inner gear ring provided in the grinding outer roller 31 and corresponding to the outer gear ring 39 one by one, and a transition wheel 38 installed in the central shaft 32 and meshingly connected with the outer gear ring 39 and the inner gear ring. Therefore, when the driving rotating shaft 37 rotates, the synchronous rotation of the multiple groups of outer gear rings 39 can be achieved, and then the grinding outer roller 31 is driven to rotate through the transition wheel 38. At the same time, the rotation of the grinding outer roller 31 will not affect the fine adjustment of the position of the grinding outer roller 31 relative to the plate frame 5 and the outer cover 4, so as to adapt to the adjustment of the grinding gap between the grinding outer roller 31 and the outer cylinder 2, and have better flexibility.

[0020] The driving member further includes a rotary motor for driving the rotary shaft 37 to rotate. The rotary motor is installed in the central shaft 32 .

[0021] An outer gear ring 8 is provided on the outside of the outer cylinder 2, and an outer gear 9 is installed on the outer frame 1. The outer gear 9 is driven to rotate by the outer motor 10 and is meshed with the outer gear ring 8. A corner of the outer frame 1 is connected to a corner motor 11, and the grinding mechanism is driven to rotate by the corner motor 11. At this point, automatic grinding switching can be achieved through the outer motor 10 and the corner motor 11. In the grinding working state, the corner motor 11 drives the outer cylinder 2 to be in a horizontal state, and after the installation is completed, the outer motor 10 can drive the outer cylinder 2 to achieve automatic rotation operation. In the unloading state after grinding, after removing the outer cover 4, the corner motor 11 can be driven to rotate 90°, so that the port of the outer cylinder 2 is tilted downward. At the same time, when the inner roller 3 is not restricted at the bottom, it can also be tilted out to facilitate subsequent cleaning operations.

[0022] The end of the outer frame 1 is provided with a pressure strip 12 which is driven to rotate by a pressing motor 13. The outer side of the outer cover 4 is also provided with a pressing groove 14 which cooperates with the pressure strip 12 to limit the position. When the pressure strip 12 is rotated into the pressing groove 14, the positioning between the outer cover 4 and the outer frame 1 can be achieved. When unloading is required, it is only necessary to drive the pressure strip 12 to rotate so that the pressure strip 12 is disengaged from the pressing groove 14 and rotated to a horizontal position, which facilitates the separation of the pressure cover from the outer frame 1.

[0023] The top and bottom of the outer cover 4 are also provided with arc-shaped blocks 15 that embrace the outside of the outer tube 2, and the arc-shaped blocks 15 located on the bottom side of the outer cover 4 are abutted against the outer frame 1, thereby improving the stability of the outer cover 4 relative to the outer tube 2 and the outer frame 1 when working.

[0024] Example 2 like Figure 6 As shown, a grinding mechanism for finely grinding food is shown. In this embodiment, the arc block 15 and the outer cylinder 2 are in contact with each other through the ball 16, so that when the outer cylinder 2 rotates, rolling friction is formed between the arc block 15 to reduce the influence of friction.

[0025] The outer cover 4 is also provided with a set of scrapers 17 resting against the top layer of the outer cylinder 2. The scrapers 17 are used to scrape off the abrasive adhering to the wall of the outer cylinder 2 when the outer cylinder 2 rotates.

[0026] The working principle of the present invention is as follows: the present invention provides a grinding mechanism for finely grinding food, which adopts a horizontal combined structure in which the outer cylinder 2 and the inner roller 3 rotate independently to achieve a high-efficiency grinding effect under automatic material leveling. At the same time, the overall detachable combined connection mode can also make it easier to clean after the grinding is completed. When the grinding operation is required, the plate frame 5 together with the inner roller 3 is first placed in the outer cylinder 2, and then the material to be ground is poured into the outer cylinder 2, and then the outer cover 4 is closed, and the outer cylinder 2 and the grinding outer roller 31 are driven to rotate in the opposite direction. At this time, the material can be driven by the outer cylinder 2 to rotate and stir in the cylinder, and at the same time The material that falls to the bottom layer can be ground when passing between the grinding outer roller 31 and the outer cylinder 2. The horizontal combination mode of the outer cylinder 2 and the grinding outer roller 31 with independent two-way rotation can not only ensure that the material falls freely when it rotates to the top layer with the outer cylinder 2, but also collides and crushes when falling. The material that falls between the outer cylinder 2 and the grinding outer roller 31 can be extruded and ground when the outer cylinder 2 and the grinding outer roller 31 rotate. Therefore, the grinding liquid is more efficient and the probability of the ground powder material adhering to the cylinder wall is reduced. At the same time, the detachable combination connection mode can also make it easier to clean after the grinding is completed.
