Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to a vibration screening and impurity removal device for puffed food raw materials. Background Art

[0002] The main raw materials for puffed foods are corn, wheat, whole wheat, oats, rice, and other grains; beans such as snow peas, red beans, and chickpeas; and tubers such as potatoes, sweet potatoes, and purple sweet potatoes. The puffing process increases the volume of the material, but due to the uneven puffing of the raw materials during the process, the puffed material needs to be screened to remove the incompletely puffed raw materials, thereby ensuring the taste and quality of the processed puffed food.

[0003] In response to the above situation, a utility model patent with the published patent number CN217190790U proposes a vibrating screening and impurity removal device for puffed food raw materials, including a vibrating screening structure and a feeding structure cooperating therewith. The vibrating screening structure includes a vibrating screening frame, a filter screen and a discharge head are provided on the vibrating screening frame, a material gathering seat is provided at the bottom of the vibrating screening frame, a discharge trough and a first fixed seat are provided on the material gathering seat, a vibration motor is provided on the first fixed seat, and a symmetrically arranged first supporting leg and a symmetrically arranged second supporting leg are provided at the bottom of the material gathering seat. The first supporting leg and the second supporting leg are connected to the base through elastic parts, and the base is provided with a feeding structure cooperating with the vibrating screening frame. The above structure is adopted, and the oblique vibrating screen is combined to use gravity to drive the raw materials to move in a certain direction. The vibrating screen is continuously formed during the movement process, and the screening efficiency is high. The adjustable feeding structure can be flexibly adjusted according to the different screening raw materials, and intermittent feeding can avoid excessive feed volume or raw materials falling and bouncing during the feeding process. The device has a reasonable structure, is easy to operate and use, and has strong practicality. However, there are still some shortcomings. When the existing device is used for screening, the raw materials are prone to agglomeration, and the screening mechanism cannot break them up. In addition, dust and impurities are prone to adhere to the surface of the raw materials and are difficult to distinguish. Utility Model Content

[0024] In this embodiment, a screen 10 is fixedly installed on the inner side of the U-shaped bracket 9, and return springs 11 are fixedly installed on both sides of the screening slider 8 of the discharge slider 6.

[0025] In this embodiment, one end of the plurality of return springs 11 is respectively connected to the inner wall of one side of the corresponding sliding groove, and a rotating shaft 12 is rotatably mounted on one side of the discharge slider 6.

[0026] In this embodiment, a motor slot is opened inside the discharge slider 6, and a rotating servo motor 13 is fixedly installed on the inner wall of one side of the motor slot. The output shaft of the rotating servo motor 13 is connected to the rotating shaft 12, so that the rotating servo motor 13 drives the rotating shaft 12 to rotate.

[0027] In this embodiment, an active crank 14 is fixedly sleeved on the rotating shaft 12 , a connecting shaft 15 is fixedly mounted on one side of the active crank 14 , and a connecting crank 16 is rotatably sleeved on the connecting shaft 15 .

[0028] In this embodiment, a fixed shaft 17 is fixedly installed on one side of the screening slider 8, and one end of the connecting crank 16 is rotatably sleeved on the fixed shaft 17 to limit the rotation range of the connecting crank 16.

[0029] In this embodiment, a collecting bin 18 is fixedly installed on one side of the fixed base 1, a collecting port is opened on the inner side of the collecting bin 18, a dust collecting port is opened on one side of the collecting bin, a barrier net 19 is snap-fitted on the inner side of the dust collecting port, and a dust collecting shell 20 is fixedly installed on one side of the collecting bin 18.

[0030] In this embodiment, a dust collecting groove is opened on one side of the dust collecting shell 20, and a dust collecting bin 21 is slidably installed in the dust collecting groove. A collecting groove is opened on one side of the collecting bin 18, and a material bin 25 is slidably installed inside the collecting groove.

[0031] In this embodiment, an air outlet is provided on an inner wall of one side of the collecting bin 18 , and an air outlet 22 is fixedly mounted on the inner side of the air outlet.

[0032] In this embodiment, a blower 24 is fixedly installed on one side of the collection bin 18, and an air duct 23 is fixedly installed on one side of the blower 24. One end of the air duct 23 is connected to the air outlet 22, so that the wind force required for air separation drives the air outlet 22 through the air duct 23.

[0033] Working principle: During production, the staff starts the machine through the control panel 3, and pours the raw materials into the machine through the feed hopper 4. At this time, the servo motor 13 is turned to start and drive the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 drives the active crank 14 to rotate. The rotation of the active crank 14 drives the connecting shaft 15 to perform a circular motion around the rotating shaft 12 as the center of the circle. The movement of the connecting shaft 15 drives the connecting crank 16 to move back and forth. The movement of the connecting crank 16 drives the discharging slider 6 and the screening slider 8 to move back and forth alternately. Since the discharging slider 6 and the screening slider 8 are fixedly installed with return springs 11 on both sides, the discharging slider 6 and the screening slider 8 move back and forth with a small amplitude and high frequency. The movement of the discharging slider 6 and the screening slider 8 drives the discharging hopper 7 and The U-shaped bracket 9 moves, and the movement of the U-shaped bracket 9 drives the screen 10 to move. The raw materials fall onto the screen 10 through the feed hopper 4, and then the raw materials are broken up and screened by the movement of the screen 10. The screened raw materials fall into the collecting bin 18 through the discharge port on one side of the discharge hopper 7, and then slide down with inertia. At this time, the wind force generated by the blower 24 reaches the wind outlet 22 through the air duct 23, and then the wind force selects the raw materials, blows the fine raw materials and dust impurities therein, and makes them pass through the barrier net 19 into the dust collecting bin 21. After the dust collecting bin 21 is full, the staff can pull it out by the handle for cleaning or replacement. The air-selected materials fall into the material bin 25 through the collection port opened in the collecting bin 18 to complete the screening.

[0034] The technical progress achieved by the present invention compared with the existing technology is that the agglomerated raw materials can be broken up and then screened, and then the finely crushed raw materials and dust impurities can be separated from the qualified raw materials by air separation mechanism, which can effectively distinguish and collect the finely crushed raw materials and dust impurities from the qualified raw materials, thereby increasing the practicality of the device.
