Description

Technical Field

[0001] This utility model relates to the field of dietary processing technology, and in particular to a screening machine for processing nutritional dietary foods. Background Technology

[0002] Existing dietary fiber usually needs to be dried to increase its shelf life and improve its taste.

[0003] Existing vibrating screens often face the following problems when processing nutritional dietary materials:

[0004] First, traditional screening machines mostly use a single axial vibration mode, which easily leads to the accumulation of dietary materials on the screening screen surface, forming a "bridging" phenomenon. This prevents some fine particles from passing through the screen holes in time, reducing screening accuracy. Second, the lack of an effective material dispersion structure during the screening process means that a large amount of material concentrated in the screening area can easily cause local overload, resulting in uneven stress on the screening screen. After long-term use, this can easily lead to mesh deformation or damage. Therefore, we provide a screening machine for nutritional dietary processing to improve upon these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a screening machine for nutritional dietary processing, which aims to improve the problems of low screening efficiency and easy material accumulation in existing screening machines.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a sieving machine for nutritional dietary processing, comprising a mounting base, wherein a connecting shell is fixedly sleeved inside the mounting base. A sieving disc is rotatably mounted inside the connecting shell via bearings, and a sieving screen is provided at the bottom of the sieving disc. A sieving vibration assembly is provided between the connecting shell and the sieving disc;

[0007] The screening vibration assembly includes a drive motor and a cam. The drive motor is fixedly mounted on the outside of the connecting housing. The cam is connected to the drive end of the drive motor. A slot is provided on the side wall of the connecting housing for the cam to extend into it. Multiple protrusions are evenly distributed on the outer periphery of the screening disc. The position of the protrusions corresponds to the rotation trajectory of the cam and can be pushed by it.

[0008] Preferably, the screening vibration assembly further includes an elastic reset member. A mounting groove is provided on the rear side of each of the protrusions on the screening disc. The elastic reset member is accommodated within the mounting groove and provides a reset force to the protrusion towards the cam.

[0009] Furthermore, the elastic reset element is a compression spring, one end of which abuts against the protrusion.

[0010] Preferably, a flow-diverting component is fixedly installed inside the screening disc. The flow-diverting component includes a guide plate fixed inside the screening disc and a plurality of inclined guide plates distributed in a ring around the outside of the guide plate. A connecting groove is formed between the guide plates and the guide plate. A plurality of material discharge holes are opened at the bottom of the guide plates. Support rods are symmetrically arranged at the bottom of the flow-diverting component. Some of the support rods have scraper strips at their bottom that contact the upper surface of the screening mesh, while other support rods have brush strips at their bottom that contact the lower surface of the screening mesh.

[0011] Preferably, the guide plate is provided with a discharge assembly, which includes a servo motor and a drive shaft fixed on the mounting base. The drive end of the servo motor is connected to the vertically arranged drive shaft. A rotating block is fixedly arranged on the top of the drive shaft. An L-shaped scraper that fits against the upper surface of the guide plate is arranged on the outer side of the rotating block.

[0012] Preferably, the drive shaft is fixedly connected to the bottom of the guide plate, and the drive shaft is movably connected to the connecting housing and the screening plate through a strip groove structure that allows axial movement.

[0013] Preferably, the bearing is a cylindrical roller bearing, the outer ring of the bearing is fixedly connected to the inner wall of the connecting housing, and the inner ring of the bearing is fixedly connected to the outer wall of the screening disc.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are as follows:

[0015] 1. In this utility model, the cam is driven by a drive motor to rotate continuously, periodically pushing the protrusions on the screening disc, and the restoring force of the compression spring is used to make the entire screening disc generate high-frequency and strong radial impact vibration. Combined with the continuously rotating diversion component, it can not only effectively enhance the screening effect of the screening mesh on dietary raw materials, but also avoid the problem of low screening efficiency caused by insufficient amplitude in traditional vibration methods.

[0016] 2. In this utility model, through the innovative design of the diversion component, the guide plate and the annular inclined guide plate are used to buffer and evenly disperse the falling material, so that it covers the entire screen surface, which greatly improves the screen utilization rate and screening efficiency, and ensures the uniformity of product particle size.

[0017] 3. In this utility model, the scraper and brush integrated into the bottom of the guide plate can simultaneously clean the upper and lower surfaces of the screen during the screening process. The scraper can scrape off the thin layer of deposits that may form on the screen surface, while the brush can remove particles that are blocked in the mesh, thus achieving self-cleaning during the screening process, effectively preventing clogging, and ensuring continuous and efficient screening operations.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Reference Figure 1-4This utility model provides an embodiment of a sieving machine for nutritional dietary processing, comprising a mounting base 1, a connecting shell 2, a sieving disc 3, a sieving vibration assembly, a diversion assembly 6, and a discharge assembly 8. The mounting base 1 serves as the supporting frame for the entire device. The connecting shell 2 is fixedly installed inside the mounting base 1. The sieving disc 3 is rotatably mounted inside the connecting shell 2 via cylindrical roller bearings 303, allowing it to rotate relative to the connecting shell 2 and move slightly axially. Simultaneously, the outer ring of the cylindrical roller bearing is fixedly connected to the inner wall of the connecting shell 2 via an interference fit, while the inner ring is also fixed to the outer wall of the sieving disc 3 via an interference fit. This connection method ensures the flexible rotation of the sieving disc 3 while providing sufficient radial support force, effectively withstanding the vibration impact and material gravity generated during the sieving process, ensuring the structural stability and service life of the sieving machine under long-term high-frequency vibration conditions. A sieving screen 301 with a specific mesh size is installed at the bottom of the sieving disc 3 for sieving nutritional dietary raw materials.

[0027] The screening vibration assembly is key to driving the vibration of the screening disc 3. The drive motor 4 is fixed to the outside of the connecting housing 2, and its output shaft is connected to a cam 401 that extends into the interior through a slotted portion on the side wall of the connecting housing 2. Multiple protrusions 302 are welded at equal intervals on the outer circumference of the screening disc 3. When the drive motor 4 drives the cam 401 to rotate, the cam 401 periodically pushes these protrusions 302, forcing the screening disc 3 to momentarily deflect against the resistance of the bearing 303. Behind each protrusion 302, the screening disc 3 has a mounting groove containing a compression spring 5, which provides a continuous restoring force to the protrusion 302, ensuring it always tends to move towards the cam 401. The combined action of the cam 401 pushing and the compression spring 5 restoring causes the screening disc 3 to generate high-frequency, small-amplitude vibrations, greatly promoting material loosening and screening.

[0028] Example 2

[0029] Reference Figure 1-2The diversion component 6 is fixed at the center of the screening disc 3. It includes a guide plate 601 and multiple inclined guide plates 602 surrounding it. A connecting slot 603 is formed between the guide plates 602 and the guide plate 601. After the material is fed onto the guide plate 601 from the top, it will naturally slide down and be distributed to the various guide plates 602 through the connecting slot 603. The material drop hole 604 at the bottom of the guide plate 602 allows the material to fall evenly and dispersedly onto the screening screen 301 for screening, avoiding excessive material thickness in the central area. The support rod 7 is fixed to the bottom of the guide plate 602. A scraper 701 is installed at the end of some support rods 7, which contacts the upper surface of the screening screen 301; a brush 702 is installed at the end of other support rods 7, which can penetrate the screening screen 301 and contact its lower surface. When the screening disc 3 vibrates, the scraper 701 and brush 702 move accordingly, cleaning the screen surface and mesh holes respectively, achieving self-cleaning.

[0030] Example 3

[0031] Reference Figure 3 The discharge assembly 8 is used to clean up any damp, agglomerated material that may be retained on the guide plate 601. A servo motor 801 is fixed to the mounting base 1, and its drive end is connected to a drive shaft 802 that extends vertically upwards, passing through the connecting housing 2 and the screening disc 3 in sequence. The drive shaft 802 has slots at its connection points with both, allowing it to move axially within a small range relative to them without interfering with the vibration of the screening disc 3. A rotating block 803 is fixed to the top of the drive shaft 802, and an L-shaped scraper 804 mounted on the outside of the rotating block 803 fits tightly against the upper surface of the guide plate 601. The outer wall of the guide plate 601 is also fixedly connected to the drive shaft 802. When needed, the servo motor 801 is activated, and the drive shaft 802 rotates the L-shaped scraper 804 to scrape off residual material from the guide plate 601 and feed it into the screening area through the connecting slot 603. Simultaneously, the rotation of the drive shaft 802 also drives the guide plate 601, which is fixedly connected to it, to rotate synchronously. This causes the entire diversion assembly 6 to vibrate along with the screening disc 3, generating a slow circumferential rotational motion. This combined motion allows the scraper strips 701 and brush strips 702 at the bottom of the guide plate 602 to perform comprehensive, thorough, and dynamic cleaning of the screening screen 301, further improving the anti-clogging effect and ensuring efficient and stable screening operations.

[0032] The implementation principle of the sieving machine for nutritional dietary processing according to this application is as follows: In use, first, the drive motor 4 and servo motor 801 are turned on. The nutritional dietary raw materials to be sieved are fed into the feed inlet at the top of the sieving machine. The raw materials first fall onto the guide plate 601, are buffered by the guide plate 601, and then slide down its surface. They are then dispersed to the inclined guide plates 602 through the connecting slots 603. The material is further buffered on the guide plates 602 and then evenly sprinkled onto the screening screen 301 of the screening disc 3 through the bottom discharge hole 604. At this time, the drive motor 4 is started, which drives the cam 401 to rotate continuously. The cam 401 periodically contacts and pushes the protrusion 302 on the outer side of the screening disc 3, causing the screening disc 3 to produce radial displacement. Meanwhile, the compression spring 5 behind the protrusion 302 is compressed and stores force. When the cam 401 disengages from the protrusion 302, the compression spring 5 releases its elastic force and pushes the protrusion 302 to reset, thereby driving the screening disc 3 to move in the opposite direction. This cycle repeats, and the screening disc 3 achieves high-frequency vibration under the drive of the cam 401 and the reset action of the compression spring 5. During the vibration of the screening disc, the internal diversion component 6 moves synchronously with the screening disc, and the support rod 7 at the bottom of the guide plate drives the scraper 701 and brush 702 to act synchronously on the screening screen 301. The scraper 701 performs high-frequency reciprocating scraping on the upper surface of the screening mesh 301, which can promptly break up the accumulation layer of material on the screen surface and prevent the material from agglomerating due to compression, thus affecting the screening efficiency. The brush 702 closely adheres to the lower surface of the screening mesh 301 for synchronous cleaning, which can penetrate deep into the mesh to brush off small particles or fibrous materials stuck in it, effectively preventing mesh blockage. At the same time, the servo motor 801 drives the drive shaft 802 to drive the rotating block 803 and the L-shaped scraper 804 to rotate slowly. The L-shaped scraper 804 adheres to the upper surface of the guide plate 601 to push any residual material towards the connecting slot 603. The fixed connection between the drive shaft 802 and the guide plate 601 causes the guide plate 601 to rotate slowly with the drive shaft 802, thereby driving the entire diversion assembly 6 to perform a circumferential rotational motion on the basis of the vibration of the screening plate 3. This composite motion mode allows the scraper 701 and brush 702 to cover the cleaning range of the screening screen 301 more comprehensively, avoiding dead corners that may be caused by cleaning in a fixed position, and significantly improving the self-cleaning effect and long-term screening stability of the screening screen 301.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
