Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food processing equipment, in particular to a shell breaking and kernel taking device which is not easy to be blocked by large shell residues. BACKGROUND

[0002] The traditional shell breaking device has fixed or inconveniently adjusted shell breaking roller spacing, which is difficult to adapt to different sizes of materials. For materials with large size difference, if the shell breaking roller spacing is too large, small particle materials may not be effectively broken; if the spacing is too small, large particle materials may be stuck between the rollers, not only reducing the shell breaking efficiency, but also possibly damaging the device parts. Moreover, the shell breaking roller of most traditional devices can only extrude the materials at a single angle, and the contact area for shell breaking is limited, which leads to incomplete breaking of part of the material shell, increases the workload of the subsequent screening process, and affects the production efficiency and product quality.

[0030] Further explanation is needed:

[0031] The primary function of the shell breaking mechanism 6 is to efficiently break the shells of the materials, and the shell breaking roller assembly 610, as the core breaking component, is composed of two groups of rubber rollers, the right rubber roller is driven by the first servo motor 611, and the materials to be broken are dropped from the feeding hopper 5 into the shell breaking roller assembly 610, and with the relative rotation of the rubber rollers, the materials are subjected to extrusion and friction, and the shell 4 is broken, thereby achieving the purpose of kernel extraction, and the spacing of the shell breaking roller assembly 610 can be flexibly adjusted by the screw rod, the internal threaded sleeve 619, the transmission rod 617 and the sliding block 603 driven by the second servo motor 620, which makes the mechanism adapt to different sizes of materials, greatly improves the applicability and success rate of shell breaking, and ensures that various materials can be effectively broken.

[0032] The shell breaking mechanism 6 also has the important functions of avoiding blockage and guiding the materials, and during the shell breaking process, the flow guide block 618 is arranged directly below the shell breaking roller assembly 610, which can smoothly guide the broken materials to the conveyor belt assembly 1, so that the broken materials will not accumulate in the shell breaking mechanism 6, effectively avoiding the problem of blockage of large shell residues, and the equipment can continue to operate stably, reducing the downtime for maintenance caused by blockage, improving the production efficiency, and ensuring the smooth operation of the entire shell breaking and kernel extraction process.

[0033] The shell breaking mechanism 6 plays a key role in ensuring the stability of the device and achieving precise adjustment. The arc-shaped spring 615 connects the first baffle 614 and the second baffle 616. When the rubber roller mounting plate 609 rotates, the arc-shaped spring 615 acts as a buffer, reducing the impact force during device operation and reducing the wear of the components. At the same time, it can reset the rubber roller mounting plate 609 after the external force disappears, ensuring the accuracy of the position of the shell breaking roller assembly 610. In addition, the closed cavity formed by the transmission rod 617, the motor mounting side plate 622, and the motor mounting plate 621 protects the second servo motor 620 and the internal threaded sleeve 619 from dust and material, prolonging the service life of the device. By cooperating the screw rod with the internal threaded sleeve 619 and the movement of the sliding block 603 and the shaft 612 in the corresponding track, the position and angle of the shell breaking roller assembly 610 can be accurately adjusted, achieving precise control of the shell breaking process.

[0034] The working principle of the above embodiment is:

[0035] First, the operator pours the material to be broken into the shell into the lower hopper 5. The lower hopper 5 is installed at the top of the shell 4, and its lower outlet is arranged directly above the shell breaking roller assembly 610. The material falls from the lower hopper 5 to the shell breaking roller assembly 610 by its own gravity, preparing for the subsequent shell breaking operation.

[0036] Second, before the material falls or according to different specifications of the material, the second servo motor 620 can be started. The second servo motor 620 drives the screw rod fixedly connected to its output end to rotate. The screw rod is threadedly connected with the internal threaded sleeve 619. The internal threaded sleeve 619 drives the transmission rod 617 connected thereto to move. The transmission rod 617 is fixedly connected to the sliding block 603 at the top. The sliding block 603 slides in the limiting groove 602 of the first limiting plate 601. The V-shaped block 604 and the dovetail block 605 drive the second limiting plate 606 to move, thereby adjusting the distance between the shell breaking roller assemblies 610 to adapt to different sizes of materials for shell breaking.

[0037] Next, the first servo motor 611 is started. The first servo motor 611 drives the right rubber roller in the shell breaking roller assembly 610 to rotate through the shaft 612. The shell breaking roller assembly 610 is divided into left and right rubber rollers. When the right rubber roller rotates, it drives the left driven roller to rotate relatively. When the material falls between the two rubber rollers, the rubber rollers squeeze and rub the material, breaking the shell 4 and achieving shell breaking and kernel extraction. At the same time, the rubber roller mounting plate 609 can rotate around the central shaft 608. The shaft 612 moves in the arc-shaped sliding groove 607 of the second limiting plate 606, so that the shell breaking roller assembly 610 can break the material at different angles to improve the shell breaking effect.

[0038] Next, in the process of breaking the shell, the fan 3 is started, and the air is blown to the shell slag treatment mechanism 2, so that the shell slag generated by breaking the shell is blown to the shell slag treatment mechanism 2 for treatment, and the material after breaking the shell continues to fall. The flow guide block 618 is arranged directly below the shell breaking roller assembly 610, and plays a flow guiding role on the material, so that the material falls smoothly onto the conveying belt assembly 1, avoiding the accumulation and blockage of the material in the shell breaking mechanism 6.

[0039] Finally, the conveying belt assembly 1 is composed of a conveying belt mechanism and a side plate. The material after breaking the shell falls on the conveying belt, the conveying belt mechanism starts to run, and the material is conveyed to the next process or collection place, completing the entire shell breaking and kernel taking work flow.

[0040] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
