Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a grinder. Background Technology

[0002] A grinding mill is a common food processing device used in daily life. It is mainly used for grinding and crushing grains such as beans, potatoes, and rice to obtain flour products or liquid products after pressing. The working principle of a grinding mill is similar to that of a traditional artificial stone mill. It has an upper and lower grinding disc arranged opposite each other. The grinding mill uses a built-in drive motor to rotate the upper or lower grinding disc, crushing the material entering between the upper and lower grinding discs. The crushed residue and liquid then enter a filter bowl for filtration, separating the solid flour and the filtered juice.

[0003] The dimensions of the upper and lower grinding discs in existing pulp mills are fixed, which limits the volume of materials that can be processed. When the particle size or volume of the material to be processed is large, the pulp mill cannot effectively crush it. Users need to use other tools to cut it before they can use the pulp mill for grinding, which causes inconvenience to users and reduces the material processing efficiency.

[0004] Therefore, there is an urgent need to design a pulping machine to solve the above-mentioned problems in the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a grinding machine that can automatically crush and grind materials, and has a wide range of applications and strong practicality.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0013] Preferably, the assembly mechanism further includes a fastening nut, which is screwed to the end of the assembly shaft and abuts against the side of the first grinding member away from the spacer.

[0014] Preferably, the assembly shaft passes through the crushing mechanism, and the crushing mechanism is rotatably coupled with the assembly shaft.

[0015] Preferably, the crushing mechanism is provided with a mounting base, the assembly shaft passes through the mounting base, a rolling bearing is provided between the assembly shaft and the mounting base, and a pressure bearing is provided between the limiting platform and the mounting base.

[0016] Preferably, the first grinding element includes a mounting frame and a grinding body, the grinding body being disposed directly opposite the second grinding element, the mounting frame including a ring cylinder and a plurality of spokes, the plurality of spokes being radially disposed on the ring cylinder, and the ring cylinder being vertically fixedly connected to the grinding body;

[0021] The beneficial effects of this utility model are as follows:

[0022] The present invention provides a pulping machine, including a crushing mechanism, a grinding assembly, and a filter bowl. The pulping machine has a receiving cavity, in which both the grinding assembly and the crushing mechanism are disposed. The grinding assembly includes a first grinding element and a second grinding element, with a grinding groove communicating with the receiving cavity between the first and second grinding elements. Since the two elements can rotate relative to each other to grind the material entering the grinding groove, the pulping machine can perform crushing and abrasive treatment on the material placed in the receiving cavity. Furthermore, a discharge channel is provided between the first and second grinding elements, communicating with the grinding groove, and the filter bowl is directly opposite the discharge channel. The material channel design allows the ground powder and liquid to enter the filter bowl through the discharge channel. The filter bowl separates the powder and liquid to obtain pure filtrate and powder products. Because the receiving chamber also contains a crushing mechanism that can cut the material in the receiving chamber, the material is first crushed into smaller pieces before grinding. This eliminates the need for pre-cutting of larger materials using other tools, greatly improving the practicality and applicability of the grinder and increasing processing efficiency.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0042] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0045] like Figures 1 to 4 As shown, this utility model provides a pulping machine, which includes a crushing mechanism 1, a grinding component 3, and a filter bowl 4. The pulping machine has a feed inlet and a receiving cavity 2. The crushing mechanism 1 is disposed in the receiving cavity 2 and is positioned directly opposite the feed inlet. The crushing mechanism 1 is used to cut the material in the receiving cavity 2. The grinding component 3 includes a first grinding element 31 and a second grinding element 32. Both the first grinding element 31 and the second grinding element 32 are disposed in the receiving cavity 2. A grinding groove and a discharge channel are provided between the first grinding element 31 and the second grinding element 32. The discharge channel is connected to the receiving cavity 2 through the grinding groove. The second grinding element 32 can rotate relative to the first grinding element 31 to grind the material entering the grinding groove. A filter screen is disposed on the filter bowl 4 and is positioned directly opposite the discharge channel.

[0046] In this embodiment, both the grinding assembly 3 and the crushing mechanism 1 are disposed in the receiving cavity 2. The grinding assembly 3 includes a first grinding element 31 and a second grinding element 32. A grinding groove communicating with the receiving cavity 2 is provided between the first grinding element 31 and the second grinding element 32. Since the two can rotate relative to each other to grind the material entering the grinding groove, the grinder can crush the material placed in the receiving cavity 2. Since there is also a discharge channel between the first grinding element 31 and the second grinding element 32, and the discharge channel is connected to the grinding groove, and the filter bowl 4 is positioned directly opposite the discharge channel, the ground powder and liquid will enter the filter bowl 4 through the discharge channel. The filter bowl 4 will then crush the powder and liquid. The material is separated to obtain pure filtrate and powder products. Since the receiving chamber 2 is also equipped with a crushing mechanism 1, which can cut the material in the receiving chamber 2, the material placed in the receiving chamber 2 will first be crushed by the crushing mechanism 1, so that the material is divided into small pieces before grinding. There is no need to use other tools to perform pre-cutting operations on larger materials, which greatly improves the practicality and applicability of the grinder and increases the processing efficiency. It can be understood that the grinder can be used for grinding small-diameter particles such as soybeans and coffee beans, as well as for grinding large-volume objects such as coconuts. At the same time, the grinder can also be used for juicing materials.

[0047] Specifically, such as Figure 3As shown, the crushing mechanism 1 is a cylindrical cutterhead commonly used in this field. The upper surface of the cutterhead body is provided with protruding blades. The cutterhead body rotates to drive the blades to cut the material. The crushing mechanism 1 is located at the bottom of the receiving cavity 2. Material fed into the inlet falls onto the crushing mechanism 1, which rotates to cut and segment the material. Figures 2 to 5 As shown, the crushing mechanism 1 and the grinding assembly 3 are arranged to form a receiving cavity 2, and the grinding groove is arranged in a ring around the crushing mechanism 1. Specifically, the first grinding element 31 is a circular grinding disc commonly used in the art. The first grinding element 31 is arranged vertically above the second grinding element 32. The crushing mechanism 1 and the inner circumferential surface of the first grinding element 31 enclose the receiving cavity 2. Since the first grinding element 31 is a circular structure and the second grinding element 32 is a cylindrical structure, and the outer edge of the first grinding element 31 is set directly opposite the outer edge of the second grinding element 32, the grinding groove is arranged in a ring around the crushing mechanism 1. When the crushing mechanism 1 rotates to cut the material, the small pieces of material that have been shredded enter the grinding groove under the action of centrifugal force for subsequent grinding processing.

[0048] The mounting position and structure of the first grinding element 51 can be set according to actual needs, as long as it ensures that the first grinding element 31 and the second grinding element 32 can rotate relative to each other to grind the material entering the grinding tank. For example, such as Figure 4 and Figure 5 As shown, the grinder also includes an assembly mechanism 5, which is disposed in the receiving cavity 2. The first grinding element 31 is disposed in the assembly mechanism 5, and the assembly mechanism 5 can drive the first grinding element 31 to approach the second grinding element 32. Specifically, the first grinding element 31 and the second grinding element 32 are arranged vertically in sequence, and the first grinding element 31 is disposed above the second grinding element 32. The assembly mechanism 5 provides support for the first grinding element 31 so that a certain gap is maintained between the first grinding element 31 and the second grinding element 32. Since the assembly mechanism 5 can drive the first grinding element 31 to approach the second grinding element 32, the user can adjust the first grinding element 31 to avoid the grinding effect being affected by the excessive gap between the first grinding element 31 and the second grinding element 32 caused by long-term wear of the grinding assembly 3.

[0049] The specific structure of the assembly mechanism 5 can be set according to actual needs; for example, such as Figures 4 to 7As shown, the assembly mechanism 5 includes an assembly shaft 51 and spacers. The assembly shaft 51 is vertically arranged in the receiving cavity 2. The assembly shaft 51 has a limiting platform 511. The first grinding part 31 is sleeved on the assembly shaft 51, and several spacers are sandwiched between the side of the first grinding part 31 near the second grinding part 32 and the limiting platform 511. Specifically, the first grinding part 31 is sleeved on the assembly shaft 51. Since spacers are sandwiched between the side of the first grinding part 31 near the second grinding part 32 and the limiting platform 511, a fixed gap can be maintained between the first grinding part 31 and the second grinding part 32. After long-term use of the grinder, the grinding component 3 will wear, and the gap between the first grinding part 31 and the second grinding part 32 will increase, causing the grinding component 3 to be unable to effectively crush and grind the material. At this time, the user can remove one or more spacers between the first grinding part 31 and the limiting platform 511, and the first grinding part 31 will fall down, thereby reducing the gap between the first grinding part 31 and the second grinding part 32, so as to ensure that the grinding component 3 can effectively and finely grind the material.

[0050] To improve the stability between the first grinding element 31 and the second grinding element 32, such as Figures 4 to 7 As shown, the assembly mechanism 5 also includes a fastening nut 52, which is screwed to the end of the assembly shaft 51 and abuts against the side of the first grinding member 31 away from the spacer. Specifically, the fastening nut 52 abuts against the first grinding member 31 to prevent the first grinding member 31 from warping due to compression when the grinding assembly 3 grinds the material, thereby ensuring that the grinding assembly 3 always effectively crushes and grinds the material. In this embodiment, the external thread at the end of the assembly shaft 51 is relatively long. Therefore, after the user removes the spacer between the first grinding part 31 and the limiting table 511, the fastening nut 52 can be tightened again to press the first grinding part 31 downwards. In another embodiment, the external thread at the end of the assembly shaft 51 is relatively short. After the user removes the spacer between the first grinding part 31 and the limiting table 511, the fastening nut 52 cannot be tightened further downwards. Therefore, the user can place the removed spacer between the fastening nut 52 and the first grinding part 31 to press the first grinding part 31 downwards.

[0051] In this embodiment, as Figure 3 , Figure 6 as well as Figure 7As shown, the assembly shaft 51 passes through the crushing mechanism 1, and the crushing mechanism 1 is rotatably engaged with the assembly shaft 51. Specifically, the first grinding element 31 is a commonly used annular grinding disc in the art, and the first grinding element 31 is vertically arranged above the second grinding element 32. The crushing mechanism 1 and the inner circumferential surface of the first grinding element 31 enclose a receiving cavity 2. The crushing mechanism 1 is a commonly used cylindrical cutter disc in the art, and the crushing mechanism 1 is located at the bottom of the receiving cavity 2. The assembly shaft 51 passes through the center position of the crushing mechanism 1, and the crushing mechanism 1 can rotate relative to the assembly shaft 51.

[0052] The mating structure between the assembly shaft 51 and the crushing mechanism 1 can be configured according to actual needs, as long as it enables rotational engagement between the two; for example, such as Figure 5 and Figure 7 As shown, the crushing mechanism 1 is provided with a mounting base 11, the assembly shaft 51 passes through the mounting base 11, a rolling bearing 53 is provided between the assembly shaft 51 and the mounting base 11, and a pressure bearing 54 is provided between the limiting platform 511 and the mounting base 11. Specifically, the mounting base 11 is provided at the center of the crushing mechanism 1. The mounting base 11 has a vertically penetrating mounting channel. The assembly shaft 51 passes through the mounting channel, and the limiting platform 511 of the assembly shaft 51 extends out of the mounting channel and abuts against the end of the mounting base 11 vertically through the pressure bearing 54. The part of the assembly shaft 51 located in the mounting channel is rotatably engaged with the mounting base 11 through the rolling bearing 53.

[0053] like Figure 3 , Figure 6 as well as Figure 7 As shown, the first grinding component 31 includes a mounting frame 311 and a grinding body 312. The grinding body 312 is positioned opposite the second grinding component 32. The mounting frame 311 includes an annular cylinder 3111 and several spokes 3112. The spokes 3112 are radially arranged on the annular cylinder 3111. The connection points of the spokes 3112 form a retaining ring 3113, which is fitted onto the assembly shaft 51. Specifically, both the annular cylinder 3111 and the grinding body 312 are cylindrical structures, and the annular cylinder 3111 is coaxially connected to the grinding body 312 in a vertical direction. The spokes 3112 are evenly distributed radially on the annular cylinder 3111, and all spokes 3112 are connected at the center of the annular cylinder 3111 to form a retaining ring 3113. The retaining ring 3113 has a through hole, and the retaining ring 3113 is fitted onto the assembly shaft 51 through the through hole. The fastening nut 52 abuts against the retaining ring 3113.

[0054] Furthermore, such as Figure 2 , Figure 6 as well as Figure 7 As shown, the grinder also includes a collection cup 6, which is vertically positioned below the filter bowl 4. The collection cup 6 is used to collect the filtrate after it has been filtered by the filter bowl 4. Figure 1As shown, in this embodiment, the collection cup 6 is provided with an outlet nozzle 61, and the filtrate collected in the collection cup 6 will flow out through the outlet nozzle 61, thus making it convenient for the user to drink.

[0055] like Figure 6 and Figure 7 As shown, the grinder also includes a drive mechanism 7. The crushing mechanism 1 and the second grinding element 32 are both fixedly connected to the filter bowl 4. The output shaft of the drive mechanism 7 is connected to the filter bowl 4, and the drive mechanism 7 drives the filter bowl 4 to rotate. Specifically, the drive mechanism 7 is a drive motor commonly used in the art. The grinding body 312 of the first grinding element 31 has a ring-shaped structure, and the second grinding element 32 has a cylindrical structure. The second grinding element 32 is fixed to the bottom of the filter bowl 4, and the crushing mechanism 1 is fixed on the second grinding element 32. The diameter of the second grinding element 32 is larger than the diameter of the crushing mechanism 1. The portion of the second grinding element 32 protruding from the outer edge of the crushing mechanism 1 is vertically aligned with the grinding body 312 of the first grinding element 31. A drive hole is opened at the center of the liquid collecting cup 6. The output shaft of the drive mechanism 7 passes through the drive hole and is connected to the bottom of the filter bowl 4, thereby driving the filter bowl 4 to rotate, which in turn drives the second grinding element 32 and the crushing mechanism 1 to rotate synchronously.

[0056] like Figure 1 , Figure 2 as well as Figure 6 As shown, the grinding mill also includes a slag bucket 8, a flow guide ring, a top cover 9, and a feed hopper 10. The flow guide ring surrounds the upper edge of the filter bowl 4 and has a flow channel. One end of the flow channel is connected to the filter bowl 4, and the other end is connected to the slag bucket 8. Therefore, the powder products accumulated in the filter bowl 4 will enter the slag bucket 8, thereby completing automatic collection. A funnel-shaped feed hopper 10 is fixedly connected above the first grinding element 31. The top cover 9 covers the slag bucket 8 and the feed hopper 10. The top cover 9 has a feed inlet, which is connected to the feed hopper. 10 is connected to the receiving cavity 2; multiple stop pins 91 are fixed on the lower surface of the top cover 9, and multiple positioning ears 101 are provided on the feed hopper 10 corresponding to the stop pins 91. The positioning ears 101 abut against the stop pins 91 along the rotation direction of the second grinding part 32. Therefore, when the grinding machine processes the material, the top cover 9 can prevent the first grinding part 31 from rotating through the abutting relationship between the stop pins 91 and the positioning ears 101, so as to ensure that the first grinding part 31 is always in a fixed and non-rotating state, thereby improving the grinding efficiency of the grinding machine.

[0057] The overall workflow of the pulping machine provided in this embodiment is roughly as follows:

[0058] First, the user puts the material into the feed inlet of the top cover 9. The material enters the receiving cavity 2 through the feed hopper 10 and falls onto the crushing mechanism 1 at the bottom of the receiving cavity 2. Then, the drive mechanism 7 is started. The output shaft of the drive mechanism 7 drives the second grinding element 32 and the crushing mechanism 1 to rotate through the filter bowl 4. The rotation of the crushing mechanism 1 can cut the material in the receiving cavity 2, thereby cutting the material into small pieces that are easy to grind. The small pieces of material after being cut enter the grinding groove surrounding the crushing mechanism 1 under the action of centrifugal force. The second grinding element 32 rotates relative to the first grinding element 31 to crush and grind the material in the grinding groove, thereby obtaining powder products and liquid. Then, the powder products and liquid will flow out through the discharge channel into the filter bowl 4. Since the filter bowl 4 is equipped with a filter screen, the filtered juice will flow into the collection cup 6 below, while the remaining powder products will accumulate in the filter bowl 4 and enter the slag bucket 8 through the flow channel of the guide ring for automatic collection. At this point, the complete grinding process of the material by the grinder is completed. When the grinding component 3 of the grinder wears out due to long-term use, a large gap will appear between the first grinding element 31 and the second grinding element 32, making it impossible to effectively grind the material. The specific adjustment method for the grinding component 3 is as follows: First, unscrew the fastening nut 52 at the top of the assembly shaft 51. Then, remove one or more spacers placed between the mounting bracket 311 and the limiting table 511, and place the removed spacers above the retaining ring 3113 of the mounting bracket 311. The first grinding element 31 will then move downward. After that, screw the fastening nut 52 onto the assembly shaft 51 and tighten it until the fastening nut 52 abuts against the spacer vertically. At this time, the grinding body 312 of the first grinding element 31 reduces the gap with the second grinding element 32, thereby ensuring effective and fine grinding of the material.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
