Description

Technical Field

[0001] The present application is used in the field of mechanical filling technology, and in particular relates to a filling device. Background Art

[0002] At present, the conventional powder filling method is to take out with a spoon and pour it into the funnel, and then use a measuring balance to fill the powder quantitatively. When filling, first use the balance to weigh the required amount of powder, put the conical funnel on the hole of the extraction plate, and then pour the quantitative powder into it, and so on to fill the hole plate.

[0028] The filling device includes a scraper plate 500 adapted to the top surface of the measuring plate 100. The top surface of the measuring plate 100 is a plane. The scraper plate 500 is used to scrape off the powder that is not filled into the first through hole 110. After the filling of the first through hole 110 in a closed state is completed, the scraper plate 500 is used to scrape off the excess powder so that the amount of powder in each first through hole 110 in a closed state is the same.

[0029] See also Figure 1In some embodiments, the slide groove is arranged in the horizontal direction, and a handle 210 for driving the push-pull plate 200 to slide in the horizontal direction is provided on the outer wall of the push-pull plate 200. The handle 210 is connected to the push-pull plate 200 through a sliding hole bolt. The handle 210 is moved to the right limit position, and the second through hole 220 on the push-pull plate 200 is not connected with the third through hole 310 of the base 300, which is equivalent to closing the unloading valve.

The positioning plate 320 is used to be fixed on the top of the hole plate 400 to be filled. The slide groove is opened at the bottom of the limiting plate 310. The third through hole 310 passes through the limiting plate 310 and the positioning plate 320.

[0031] See also Figure 2 The limiting plate 310 and the positioning plate 320 are connected by bolts 330 , and the bolts 330 are arranged around the outer circumference of the base 300 .

[0032] See also Figure 2 An adjustable spring 120 is provided at the bottom of the measuring plate 100. The adjustable spring 120 is located between the measuring plate 100 and the limit plate 310. The adjustable spring 120 is located at the four corners of the measuring plate 100. The adjustable spring 120 is used to adjust the amount of powder filling, and can be used to distribute different masses (or different powders). Specifically, the adjustable spring includes a coil spring, a Kia spring and a hydraulic spring. Among them, the coil spring is the most common type of adjustable spring. It is made of metal wire wound into a spiral shape and has a high elastic coefficient and elastic restoring force. The coil spring can be designed to adjust the number of coils and the wire diameter as needed, so as to achieve different The pneumatic spring is a kind of spring that uses gas inflation to adjust the spring stiffness. It usually consists of a sealed airbag and an inflation device. The stiffness is adjusted by changing the gas pressure to adjust the spring. It has strong adjustability, fast response, good shock absorption effect and light weight. The hydraulic spring uses the flow of liquid to adjust the spring stiffness. It consists of a sealed container and a certain amount of liquid. The stiffness is adjusted by changing the flow rate or damping of the liquid. It can withstand high loads, has good stability and high reliability.

[0033] See also Figure 3 and Figure 4The measuring plate 100 and the limiting plate 310 are connected by a pin 130. In other words, the bottom of the measuring plate 100 is positioned by a pin 130.

[0034] The limit plate 310 and the push-pull plate 200 have a mechanical limit installation, and the positioning plate 320 and the limit plate 310 are fixed by bolt connection. The bolt connection can provide a high connection strength, and the bolt connection is detachable, which means that the connection can be disassembled at any time for maintenance, replacement of parts or other adjustments. Compared with permanent connection methods such as welding, bolt connection is more flexible, and bolt connection allows the tightness of the connection to be controlled by adjusting the tightness of the nut. This makes it possible to adjust the tightness of the connection in different situations to meet different needs.

[0035] As a preferred embodiment of the present invention, see Figure 3 and Figure 4 The fixing bolts 150 fasten and install the measuring plate 100 and the limit plate 310. There are corresponding spring concentric mounting holes on the measuring plate 100 and the limit plate 310. Correspondingly, the measuring tool can be used to ensure the flatness tolerance and measure the plane height. The fixing bolts 150 can be adjusted up and down to control the distance between the measuring plate 100 and the limit plate 310, so as to achieve the distribution of different masses (or different powders) into each hole.

[0036] As a preferred embodiment of this application, see Figure 1 The measuring plate 100 is provided with a bushing 130, which is located in the first through hole 110. The bushing 130 and the first through hole 110 are interference fit, so that a certain pressure needs to be applied when the bushing 130 is installed in the hole, so as to achieve sealing in the powder packaging process. The bottom of the bushing 130 extends into the third through hole 310. Through the setting of the bushing and the expansion and contraction of the adjustable spring 120, the powder filling amount of the first through hole 110 in the blocked state is adjusted to achieve control of the powder filling amount, so that the filling is more accurate and meets the needs of the user. The bushing 130 is mainly used to store a certain amount of powder. Specifically, the bushing 130 can increase the strength and rigidity of the first through hole 110 to prevent the first through hole 110 from being used. The bushing 130 is arranged at the position of the first through hole 110 to effectively improve the durability and reliability of the structure; the first through hole 110 is often filled with powder, and the bushing 130 can reduce direct contact, thereby reducing friction and wear. The bushing 130 is usually made of materials with a low friction coefficient, such as polymers, coatings, etc., which can reduce the friction between parts such as connecting rods or bearings and extend the service life; the bushing 130 can also reduce the generation of noise and vibration; the first through hole 110 may be affected by corrosion or oxidation, and the bushing 130 can provide a protective layer to protect the inner wall of the first through hole 110 from corrosion or oxidation, thereby extending the service life of the structure and the connector.

[0037] See also Figure 2 A limiting portion 321 is provided on the top of the positioning plate 320, and the limiting portion 321 is located at the outer periphery of the measuring plate 100. The outer periphery of the positioning plate 320 protrudes upward to form the limiting portion 321. In other words, at the same time, the outer frame of the measuring plate 100 cooperates with the inner slide groove frame of the limiting plate 310 to provide a stable guiding effect for adjusting the up and down strokes.

[0038] See also Figure 1 The upper top surface of the measuring plate 100 extends outward to form a temporary storage platform 140, and a powder recovery groove 141 is on the temporary storage platform 140. The scraper plate 500 scrapes the powder onto the temporary storage platform 140 and drops it into the powder recovery groove 141 for secondary utilization.

[0039] Preferably, the well plate 400 to be filled in the present application is a 96-well plate, i.e., a (96)-well solid-phase liquid-liquid extraction plate, and the positioning plate 320 is connected to the well plate 400 to be filled by a snap-fit ​​feature. The filling device of the present application is configured to fill a 48-well plate at a time, and after filling the 48 wells on one side, move to the other side of the 96-well plate, repeat the operation, and fill the 48 wells on the other side. Thus, the (96)-well solid-phase liquid-liquid extraction plate 9 can be completely filled.
