Description

Technical Field

[0001] This invention relates to the field of medical and health product manufacturing equipment, specifically a sieving device for deep-sea fish oil microcapsules. Background Technology

[0002] Fish oil soft capsules are a popular health supplement, mainly extracted from deep-sea fish such as salmon and sardines. They have significant health benefits, effectively regulating blood lipids, reducing blood viscosity, preventing thrombosis, preventing cardiovascular and cerebrovascular diseases, and crossing the blood-brain barrier to activate brain cells, promote brain development, prevent Alzheimer's disease, improve vision, and delay vision decline.

[0003] In existing technologies, when screening deep-sea fish oil, the surface of the oil has a certain degree of adhesion. When multiple deep-sea fish oils stick together during the screening process, it can easily lead to insufficient screening effect. At the same time, after the screening machine has been used for a certain period of time, some impurities often stick to the inner wall of the screening holes, causing some screening holes to malfunction and thus affecting screening efficiency. Therefore, there is a need for a device that can prevent deep-sea fish oil from sticking together and automatically clean the inner wall of the screening holes to avoid insufficient screening effect and low screening efficiency.

[0007] Preferably, the coordination component includes a first arc-shaped frame disposed between each group of control frames. The side end of the first arc-shaped frame is connected to the side end of one of the adjacent control frames. The drive shaft is rotatably engaged with the first arc-shaped frame. The drive shaft has an opening inside the first arc-shaped frame. Inclined plates are respectively provided at both ends of the opening. The other end of the inclined plate is connected by an obliquely arranged connecting rod. A triangular piece is provided on the side of the connecting rod facing the first arc-shaped frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] In this invention, when the screening machine is performing screening, the drive component is controlled to drive several coordinating components to work synchronously. The output component then blows the deep-sea fish oil on the screening plate in a wide range. With the cooperation of the screening machine, this prevents the deep-sea fish oil from adhering to each other. Simultaneously, the drive component intermittently stops the coordinating components, changing the output end to drive the changing components. This causes the output components to move in an arc along the upper and lower sides of the screening plate. When they reach the bottom of the screening plate, the backflushing component cleans the inner wall of each screening hole on the screening plate, flushing the adhering impurities back to the top of the screening plate for re-screening. This process prevents the deep-sea fish oil from adhering together during screening, thus improving the screening effect. It also prevents impurities from adhering to the inner wall of the screening holes, which could cause some screening holes to malfunction and affect screening efficiency.

[0014] In this invention, by using components such as the drive component in cooperation, the coordination component and the change component can be controlled to drive separately under a single drive, thereby improving the ease of use of the device and facilitating the switching of the working state of the output component.

[0015] In this invention, by using components such as the coordination component and the variable component in combination, the deep-sea fish oil can be prevented from sticking together during the screening process, thereby improving the screening effect. At the same time, it also prevents some impurities from sticking to the inner wall of the screening holes, which would prevent some screening holes from working properly and thus affect the screening efficiency.

[0016] In this invention, by setting a linkage bevel gear with a larger diameter, the blower intermittently performs backflush operation after working on the surface of the screening plate, thereby further improving the practicality of the device. Attached Figure Description

[0041] In this embodiment, as Figure 9 As shown, the overall diameter of the linkage bevel gear 97 is larger than the overall diameter of the control bevel gear 98.

[0042] The invention provides the following usage method and advantages: A sieving device for deep-sea fish oil microcapsules, the working process of which is as follows:

[0043] like Figures 1 to 15 As shown, during screening by the screening machine 2, the drive motor 57 is controlled to rotate, thereby driving the drive shaft 55 to rotate. The meshing drive gear 59 and transmission gear 60 drive the control shaft 56 to rotate synchronously. The slider 61 drives each sliding sleeve 62 to rotate. The engagement between one meshing sleeve 63 and the auxiliary sleeve 73 drives one of the control gears 74 to rotate, causing the sliding toothed rod 76 to slide along the control frame 53, which in turn drives the drive rod 71 to rotate. When the sliding toothed rod 76 slides and causes the wedge block 77 to abut against the side of the locking post 70, the auxiliary T-shaped rod 68 deflects to the other side. The extension spring 69 drives the active T-shaped rod 66 to deflect synchronously on the support rod 67, thereby passing through the arc block 65 and the annular groove 64. In coordination, one of the engaging sleeves 63 is pulled to slide under the action of the sliding sleeve 62 and the slider 61, so that it disengages from the auxiliary sleeve 73. The other engaging sleeve 63 engages with the auxiliary sleeve 73 on the side of the control rod 72, thereby transmitting power and causing the sliding toothed rod 76 to slide in the opposite direction to the previous one, until the other wedge block 77 engages with the other locking pin 70. During this process, the one-way bearing 75 ensures that both the drive rod 71 and the control rod 72 can only rotate in one direction. As a result, when the drive rod 71 rotates, the control rod 72 cannot rotate, and when the control rod 72 rotates, the drive rod 71 cannot rotate. This allows the coordination component 8 and the change component 9 to be driven separately under a single drive, thereby improving the ease of use of the device and facilitating the switching of the working state of the output component 11.

[0044] When the drive rod 71 rotates, the inclined plate 82 at each opening and the connecting rod 83 cooperate, and under the action of the triangular piece 84, the control arc block 85 is driven to reciprocate along the first arc frame 81. Through the cooperation of the telescopic rod 86 and the connecting card seat 114, the second connecting block 111 and the fan 115 move synchronously. At this time, the electromagnet 112 is not energized, the first connecting block 93 does not move, thereby driving the fan 115 to reciprocate along the screen plate 3, and then in cooperation with the screening machine 2. To prevent deep-sea fish oil from sticking together during the screening process and thus improve the screening effect, after the drive rod 71 stops rotating, the control arc block 85 resets. At this time, the control rod 72 rotates, thereby driving the adjacent auxiliary shaft 99 to rotate. Under the action of the control bevel gear 98, the meshing linkage bevel gear 97 rotates. Through the action of the transmission bevel gear 100 and the transmission shaft 101, the linkage bevel gear 97 in each set of control frames 53 rotates synchronously. Through the crank 94, the first connecting block is driven. 93 slides along the second arc-shaped frame 91. At this time, the infrared sensor 113 energizes the electromagnet 112, which in turn drives the second connecting block 111 to move synchronously, causing the fan 115 to move along the second arc-shaped frame 91. When it moves to one end, the fan 115 moves to the outside of the screening plate 3, and under the action of the crank 94, it drives the second arc-shaped frame 91 to swing under the action of the rotating shaft 92, thereby driving the fan 115 to pass along the open side of each air collecting groove 121, so that the fan 115... The output end is directed towards the air collection trough 121, and after output, the airflow is discharged through each vent 122, thereby forming a backflushing effect on the screening holes on each screening plate 3. After moving to the other end of the second arc frame 91, the blower 115 is driven to move back to the top of the screening plate 3 until it is reset. Under the action of the drive assembly 5, the control rod 72 stops rotating, and the drive rod 71 rotates again to work. This avoids some debris adhering to the inner wall of the screening holes, which would prevent some screening holes from working properly and thus affect the screening efficiency.

[0045] By setting a larger diameter linkage bevel gear 97, the blower 115 can intermittently perform backflush operation after working on the surface of the screening plate 3, thereby further improving the practicality of the device.
