DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The purpose of the present invention is to provide a nut fine cutting machine to solve the problems existing in the prior art. The machine can cut nuts into various sizes and has high chopping efficiency, low noise and long service life.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1-6 As shown, this embodiment provides a nut fine cutting machine, including a frame 1, and a conveying module 2, a material distribution module and a plurality of crushing modules installed on the frame 1. The frame 1 plays a role in supporting the whole. The conveying module 2 is arranged near the bottom of the frame 1, and the upper end surface of the conveying module 2 is used to convey nuts, so that the nuts are crushed as the nuts are conveyed. The multiple crushing modules are arranged in sequence along the conveying direction of the conveying module 2, and each crushing module is located above the conveying module 2, ensuring that the crushing module can act on the nuts on the conveying module 2, and each crushing module crushes the nuts on the conveying module 2 in turn. The multi-stage crushing method can be used It can ensure the crushing effect, especially when used to crush nuts into small particles, it can improve the crushing efficiency and crushing effect, and effectively solve the problem of low output of traditional nut cutters. The material distribution module is used to distribute the nuts on the conveying module 2 evenly, and arrange the nuts on the conveying module 2 in a single layer to ensure that the nuts are evenly distributed, thereby facilitating the crushing of the nuts and improving the nut crushing efficiency. The crushing module can rotate relative to the conveying module 2 and roll-cut the nuts on the upper end of the conveying module 2. Compared with the traditional reciprocating chopper-type crushing, the rolling crushing method has low noise, low wear and low maintenance cost, thereby extending the service life.

[0030] Specifically, the multiple crushing modules are divided into multiple primary crushing components 3 and multiple secondary crushing components, and the primary crushing components 3 are arranged near the entrance of the nuts, and the secondary crushing components are arranged near the outlet of the nuts. Then, each primary crushing component 3 is used to perform preliminary rolling and crushing on the nuts entering the nut fine cutting machine in turn, and crush the nuts into larger particles. Multiple secondary crushing components are used to roll and cut the nuts again after being rolled by the primary crushing component 3, so as to achieve fine cutting of the nuts, crush the nuts into smaller particles, and improve the nut crushing effect.

[0031] The frame 1 includes a main frame and a sub-frame. Both the main frame and the sub-frame are hollow inside to provide installation and operation space. One end of the main frame and one end of the sub-frame are fixedly connected, and the main frame and the sub-frame are internally connected. The conveying module 2 can pass through the main frame and the sub-frame in sequence. Each primary crushing component 3 is installed in the main frame, and each secondary crushing component is installed in the sub-frame to achieve multi-stage crushing of nuts.

[0032] Both the main frame and the sub-frame are cubic frames, and a plurality of reinforcing rods are provided on the main frame and the sub-frame, thereby increasing the overall strength and supporting stability of the main frame and the sub-frame.

[0033] The material distribution module is installed in the sub-frame, and can distribute the nuts moved into the sub-frame, so that the nuts can be rolled and crushed by the secondary crushing assembly. The material distribution module includes a material distribution drive motor 7 and a material distribution roller 5. The material distribution drive motor 7 is installed on the sub-frame, and the material distribution drive motor 7 is used to provide driving force. The output shaft of the material distribution drive motor 7 is connected to one end of the material distribution roller 5, and the other end of the material distribution roller 5 is rotatably connected to the sub-frame to ensure the stability of the material distribution roller 5 during rotation. The material distribution drive motor 7 can drive the material distribution roller 5 to rotate. The rotation direction of the material distribution roller 5 is opposite to the rotation direction of the secondary crushing assembly, ensuring that the nuts can pass through the material distribution roller 5 smoothly and reach the secondary crushing assembly. There is a gap between the lower end of the material distribution roller 5 and the upper surface of the conveying module 2 for allowing a single layer of nuts to pass through. As the conveying module 2 conveys the nuts, the nuts are arranged in a single layer after passing through the material distribution roller 5, which is convenient for the subsequent secondary crushing assembly to effectively crush the nuts.

[0034] The nut fine cutting machine provided in this embodiment also includes a crushing drive motor 8 and a speed regulator. The crushing drive motor 8 is connected to the speed regulator. The speed regulator is used to adjust the rotation speed of the crushing drive motor 8. The crushing drive motor 8 is used to drive the crushing module to rotate.

[0035] The primary crushing assembly 3 is a crushing roller, and a plurality of rolling grooves are formed on the circumferential outer wall of the crushing roller; the secondary crushing assembly includes a crushing element and a cleaning element 6, and the crushing element is located below the cleaning element 6; the crushing element includes a crushing roller shaft 12, a plurality of crushing pads 14 and a plurality of rollers 13, and the crushing roller shaft 12 is transmission-connected to the crushing drive motor 8 and can rotate under the drive of the crushing drive motor 8. As a preferred embodiment, the output shaft of the crushing drive motor 8 is connected with a synchronous wheel, and the end of each crushing roller shaft 12 is also coaxially connected with a synchronous wheel. The synchronous wheels are connected by a synchronous belt drive, so that it is possible to simultaneously drive multiple crushing roller shafts 12 to rotate by one crushing drive motor 8. The rollers 13 and the crushing pads 14 are both annular, and each crushing pad 14 is sleeved on the outer circumference of the crushing roller shaft 12, and the plurality of crushing pads 14 are arranged in sequence along the length direction of the crushing roller shaft 12, and there is an installation spacing between adjacent crushing pads 14. Each roller 13 is sleeved on the crushing roller shaft 12. The outer periphery of the crushing roller shaft 12 is arranged in sequence along the length direction of the crushing roller shaft 12, which is convenient for crushing nuts at various locations in the width direction of the conveying module 2. When the roller cutter 13 is worn, the corresponding roller cutter 13 can be directly replaced, and the maintenance cost is low. As a preferred solution of this embodiment, threaded sections are provided at both ends of the crushing roller shaft 12. By tightening nuts on the threaded sections at both ends, the roller cutter 13 and the crushing pad 14 can be pressed. The multiple roller cutters 13 and the multiple crushing pads 14 are alternately arranged along the length direction of the crushing roller shaft 12, and the inner ring of the roller cutter 13 can be inserted into the installation spacing, and the outer ring of the roller cutter 13 protrudes from the outer ring of the crushing pad 14, ensuring that the roller cutter 13 can act on the nuts. By setting the spacing between adjacent crushing pads 14, the spacing between adjacent roller cutters 13 can be adjusted to ensure that nut particles of different particle sizes can be rolled out, and the crushing roller shaft 12 drives the roller cutter 13 to perform circular motion, with low noise, low wear and low maintenance cost. In actual application, this embodiment can be designed with various specifications of crushing pads 14. When the crushing target parameters need to be adjusted, the corresponding crushing pads 14 can be directly replaced, which has good adaptability. A cleaning distance is formed between adjacent roller cutters 13.

[0036] The cleaning element 6 includes a cleaning roller 15, a plurality of cleaning pads and a plurality of combing discs 16. The end of the cleaning roller 15 is connected to the end of the corresponding crushing roller 12 by transmission, and can drive the cleaning roller 15 to rotate as the crushing roller 12 rotates. The cleaning pads and the combing discs 16 are both annular, and each cleaning pad is sleeved on the outer periphery of the cleaning roller 15, and the plurality of cleaning pads are arranged in sequence along the length direction of the cleaning roller 15, and there is an insertion spacing between adjacent cleaning pads. Each combing disc 16 is sleeved on the outer periphery of the cleaning roller 15, and the plurality of combing discs 16 are arranged along the length direction of the cleaning roller 15. 5, multiple comb discs 16 and multiple cleaning pads are alternately arranged along the length of the cleaning roller shaft 15, and the inner rings of the comb discs 16 can be inserted into the insertion spacing, and the outer rings of the comb discs 16 protrude from the outer rings of the cleaning pads. Multiple comb discs 16 and multiple rollers 13 are alternately arranged, and the outer rings of the comb discs 16 can extend into the cleaning spacing. Thus, the rotation of the comb discs 16 can clean the nuts within the cleaning spacing, preventing the accumulation of nut fragments between adjacent rollers 13, which would cause the rollers 13 to fail, thereby improving the nut crushing effect and nut crushing efficiency. At the same time, when it is necessary to adjust the crushing target parameters, cleaning pads of different thicknesses can be replaced to adjust the spacing between adjacent comb discs 16, thereby adapting to rollers 13 with different spacings.

[0037] The outer ring of the comb plate 16 is provided with a plurality of grooves, and the plurality of grooves are arranged circumferentially around the center of the comb plate 16, so that the comb plate 16 forms a sawtooth-like structure, which can pick up the nut particles within the cleaning interval as the comb plate 16 rotates. The positions of the grooves on the plurality of comb plates 16 correspond to each other, and the width of the insertion interval is slightly larger than the thickness of the comb plate 16, so that there is a certain gap between the comb plate 16 and the cleaning pad, allowing the comb plate 16 to shake slightly. The inner ring diameter of the comb plate 16 is larger than the outer diameter of the cleaning roller 15, so that when the comb plate 16 is installed on the outer periphery of the cleaning roller 15, it is an eccentric structure relative to the cleaning roller 15. In this way, under the action of gravity and rolling eccentricity, the comb plate 16 can realize self-correction, thereby reducing the friction between the comb plate 16 and the hob 13, while avoiding affecting the rotation of the hob 13, it also extends the service life.

[0038] As a preferred solution in this embodiment, there are two secondary crushing components, which are the primary rolling cutting element 9 and the secondary rolling cutting element 10 in the conveying direction of the conveying module 2, and the spacing between the rollers 13 of the primary rolling cutting element 9 can be designed to be larger than the spacing between the rollers 13 of the secondary rolling cutting element 10, thereby realizing step-by-step rolling cutting of the nuts and improving the rolling cutting effect and efficiency.

[0039] As a preferred solution in this embodiment, for the design of the primary crushing assembly 3, two primary crushing assemblies 3 can be designed to rotate simultaneously and crush the nuts in sequence. The nuts after preliminary crushing fall onto the conveying module 2 and are then crushed by subsequent secondary crushing assemblies.

[0040] As a preferred solution in this embodiment, a feed cover plate 4 is further installed at the upper end of the main frame. A feed port is provided on the feed cover plate 4 , and the feed port is located above between the two primary crushing assemblies 3 .

[0041] As a preferred solution in this embodiment, a discharging element 11 is further installed at the end of the sub-frame. The discharging element 11 is arranged corresponding to the conveying end of the conveying module 2 and is used to discharge the crushed nut particles on the conveying module 2.

[0042] The conveying module 2 includes a conveying motor, a conveyor belt and multiple transmission rollers. The conveying motor is installed on the frame 1, and the conveying motor is coaxially connected to one of the transmission rollers. The multiple transmission rollers are connected by a conveyor belt to achieve stable transmission of the conveyor belt. Those skilled in the art can also choose other conveying structures according to actual needs.

[0043] The specific working process of this embodiment is as follows: the nuts enter the primary crushing component 3, and after preliminary crushing by the primary crushing component 3, they fall into the conveying module 2. Driven by the conveying module 2, the nuts reach the material distribution module. As the material distribution module rotates, the nuts can be evenly arranged in a single layer after passing through the material distribution module, and are conveyed to the bottom of the primary rolling and cutting element 9 through the conveying module 2 for a fine cutting. The nuts that have completed the fine cutting continue to be conveyed with the conveying module 2, and then are finely cut for the second time by the secondary rolling and cutting element 10, and finally the nuts are crushed.

[0044] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
