Description
A grinding mechanism Technical Field
[0001] This utility model relates to the field of grinding technology, and specifically to a grinding structure. Background Technology
[0002] When making nut, bean, or fruit juice drinks, the nuts, beans, fruits, and water are first mixed to form a material. The material is then fed into a grinding device to be ground to form a coarse liquid. The coarse liquid contains large particles of nuts, beans, or fruits. The grinding device is a coarse grinding device.
[0003] In existing grinding equipment, because it is a coarse grinding equipment, it is not necessary to crush the material into very small pieces. Therefore, the blades inside are sparsely arranged and the rotation speed is slow. Some smaller materials, such as beans and nuts, can easily leak out from the gaps between the blades and enter the next production equipment without being crushed. This can easily cause the next production equipment to malfunction, trigger alarms, and affect continuous production. Summary of the Invention
[0004] In view of this, the present invention provides a grinding structure to solve the problem that some small materials are easy to leak out from the gap between the blades and enter the next production equipment without being crushed, which can easily cause the next production equipment to malfunction, trigger alarms, and affect continuous production.
[0005] This utility model provides a grinding mechanism, including:
[0006] A grinding housing having a grinding chamber inside;
[0007] A grinding assembly is disposed within the grinding chamber. The grinding assembly includes a first grinding cutter, a second grinding cutter, and a rotating shaft. The first grinding cutter and the second grinding cutter are fixedly disposed on the rotating shaft. The second grinding cutter is located below the first grinding cutter. The first grinding cutter forms an angle with the horizontal plane, and the second grinding cutter is horizontally disposed.
[0008] In one alternative embodiment, the first grinding tools arranged on both sides of the rotating shaft correspond to each other.
[0009] In one alternative embodiment, the angle between the first grinding tool and the horizontal plane is 15-20°.
[0010] In one alternative implementation, the axially adjacent first grinding tools are staggered.
[0011] In one optional embodiment, the second grinding tool includes a cutting disc and a cutting blade. The cutting disc is sleeved on the rotating shaft and fixedly connected to the rotating shaft. The cutting blade is horizontally arranged, with one end of the cutting blade fixedly connected to the outer peripheral surface of the cutting disc, and the other end of the cutting blade extending toward the inner wall of the grinding chamber and having a clearance fit with the inner wall of the grinding chamber.
[0012] In one alternative embodiment, the grinding assembly further includes a sieve plate detachably disposed within the grinding chamber, the sieve plate being located below the second grinding cutter.
[0013] In one optional embodiment, it further includes: a fixed bushing, the fixed bushing being sleeved on the rotating shaft, the fixed bushing being fixedly disposed in the grinding chamber, the fixed bushing being provided with a support, and the sieve plate being sleeved on the support and overlapping with the bottom surface of the support.

[0017] Beneficial effects:
[0018] 1. This utility model discloses a grinding structure in which the first and second grinding blades crush materials in water when they rotate. The rotational force generated by the rotation mixes the materials with the water. At the same time, because the first grinding blade is set at an angle, it can generate a downward force, which will cause a certain impact on the materials, which helps to crush the materials. It can also guide the materials to the grinding range of the second grinding blade. The second grinding blade can fully crush the materials in the water, preventing the materials from entering the next production equipment without being crushed.
[0019] 2. In this grinding structure, the first grinding cutters on the left and right sides are at the same height and correspond to each other. When the first grinding cutter rotates, the corresponding first grinding cutter can prevent the water in the grinding chamber from becoming turbulent and prevent the material from being unable to be guided to the second grinding cutter.
[0020] 3. The grinding structure of this device allows the screen plate to assist the second grinding blade in grinding, ensuring the crushing effect of the material and preventing the material from entering the next production equipment without being crushed. The screen plate is detachable, which facilitates the replacement of screen plates with different apertures. At the same time, when one side of the screen plate is severely worn, the screen plate can be reused on the other side, which improves the service life of the screen plate and avoids wasting resources.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0027] The embodiments of this utility model are described below with reference to Figures 1 and 2.
[0028] According to an embodiment of the present invention, a grinding structure is provided, including: a grinding housing 1 and a grinding assembly.
[0029] Specifically, the grinding housing 1 has a grinding chamber. The grinding assembly is disposed in the grinding chamber and has a first grinding cutter 2, a second grinding cutter 4 and a rotating shaft 3. The first grinding cutter 2 and the second grinding cutter 4 are fixedly disposed on the rotating shaft 3. The second grinding cutter 4 is located below the first grinding cutter 2. The first grinding cutter 2 has an angle with the horizontal plane, and the second grinding cutter 4 is horizontally disposed.
[0030] In this embodiment, the first grinding blade 2 is angled and forms an angle with the horizontal plane. Four first grinding blades 2 are mounted on the rotating shaft 3, respectively positioned on both sides of the shaft 3, spaced apart along the axial direction of the shaft 3. The second grinding blade 4 is located below the first grinding blades 2. The rotating shaft 3 can simultaneously drive the first grinding blades 2 and the second grinding blade 4 to rotate. When the first grinding blades 2 and the second grinding blade 4 rotate, they break up the materials in the water. The rotational force generated by the rotation mixes the materials with the water. At the same time, because the first grinding blade 2 is angled, it generates a downward force, which impacts the materials, aiding in their crushing. It also guides the materials into the grinding range of the second grinding blade 4, where the second grinding blade 4 thoroughly crushes the materials in the water.
[0031] Preferably, in this embodiment, four first grinding cutters 2 are fixedly arranged on the rotating shaft 3. In other embodiments, six or eight or other numbers of first grinding cutters 2 may be arranged on the rotating shaft 3. The specific number of first grinding cutters 2 can be determined according to the size of the grinding housing 1, the length of the rotating shaft 3 and the process requirements.
[0032] In one embodiment, the first grinding tools 2 arranged on both sides of the rotating shaft 3 correspond to each other.
[0033] In this embodiment, as shown in Figure 1, four first grinding blades 2 are respectively arranged on both sides of the rotating shaft 3. The first grinding blades 2 on the left and right sides are at the same height and correspond to each other. When the first grinding blades 2 rotate, the corresponding first grinding blades 2 can prevent the water in the grinding chamber from becoming turbulent, and prevent the material from being unable to be guided to the second grinding blades 4.
[0034] In one embodiment, the angle between the first grinding tool 2 and the horizontal plane is 15-20 degrees.
[0035] In this embodiment, the angle between the first grinding tool 2 and the horizontal plane is 17°. In other embodiments, the angle between the first grinding tool 2 and the horizontal plane may be 15° or 20°, or other angles.
[0036] In one embodiment, the first grinding tools 2 that are axially adjacent are staggered.
[0037] In this embodiment, as shown in FIG1, the first grinding cutter 2 on the rotating shaft 3 is arranged alternately with the upper first grinding cutter 2 and the lower first grinding cutter 2, thereby increasing the grinding range of the first grinding cutter 2.
[0038] In one embodiment, the second grinding tool 4 includes a cutting disc 401 and a cutting blade 402. The cutting disc 401 is sleeved on the rotating shaft 3 and fixedly connected to the rotating shaft 3. The cutting blade 402 is horizontally arranged. One end of the cutting blade 402 is fixedly connected to the outer peripheral surface of the cutting disc 401, and the other end of the cutting blade 402 extends toward the inner wall of the grinding chamber and is in clearance fit with the inner wall of the grinding chamber.
[0039] In this embodiment, the cutter head 401 is sleeved on the rotating shaft 3 and fixedly connected to the rotating shaft 3. The blade 402 is horizontally arranged, and one end of the blade 402 is fixedly connected to the cutter head 401. The rotating shaft 3 drives the blade 402 to rotate through the cutter head 401. Two blades 402 are fixedly arranged on the cutter head 401, and the two blades 402 are spaced apart along the circumference of the cutter head 401.
[0040] In other embodiments, the cutter head 401 may be provided with three or four other blades 402.
[0041] In one embodiment, the grinding assembly further includes a sieve plate 5, which is detachably disposed within the grinding chamber and located below the second grinding cutter 4.
[0042] In this embodiment, as shown in Figures 1 and 2, the sieve plate 5 is detachably disposed below the second grinding blade 4. The sieve plate 5 has several sieve holes. The second grinding blade 4 can rotate relative to the sieve plate 5. When the material is larger than the diameter of the sieve holes, it will be blocked by the sieve plate 5, preventing the material from entering the discharge port 9 and exiting the grinding chamber. The second grinding blade 4 will continuously grind the material retained on the sieve plate 5. After multiple grinding operations by the second grinding blade 4, the material can be pulverized to a size that can pass through the sieve holes. The sieve plate 5 assists the second grinding blade 4 in grinding to ensure the crushing effect of the material and prevent the material from entering the next production equipment without being crushed. The detachable sieve plate 5 facilitates the replacement of sieve plates 5 with different hole diameters. Furthermore, when one side of the sieve plate 5 is severely worn, the other side can be reused, improving the service life of the sieve plate 5 and avoiding resource waste.
[0043] In one embodiment, it further includes: a fixed bushing 6, which is sleeved on the rotating shaft 3 and fixedly disposed in the grinding chamber. The fixed bushing 6 is provided with a support 601, and the sieve plate 5 is sleeved on the support 601 and overlaps with the bottom surface of the support 601.
[0044] In this embodiment, as shown in Figure 2, the fixed bushing 6 is fixedly sleeved on the rotating shaft 3. When the rotating shaft 3 rotates, the fixed bushing 6 will not rotate. The sieve plate 5 is sleeved on the fixed bushing 6. The upper end surface of the fixed bushing 6 has a support 601. The sieve plate 5 overlaps with the bottom surface of the support 601. The support 601 can support the sieve plate 5.
[0045] In one embodiment, the grinding housing 1 has an annular groove 7, and the sieve plate 5 overlaps with the annular groove 7.
[0046] In this embodiment, the outer edge of the sieve plate 5 extends into the annular groove 7, which can limit and support the sieve plate 5. The annular groove 7 and the support platform 601 cooperate to support and limit the sieve plate 5.
[0047] In one embodiment, a sealing structure is provided between the fixed bushing 6 and the rotating shaft 3, and the sealing structure is provided at both ends of the fixed bushing 6.
[0048] Preferably, the sealing structure can be a sealing ring.
[0049] In one embodiment, the grinding housing 1 has a feed inlet 8 and a discharge outlet 9 at its two ends, respectively, and the feed inlet 8 and the discharge outlet 9 are respectively connected to the grinding chamber.
[0050] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
