Description

Technical Field

[0001] This utility model belongs to the field of [field name], specifically relating to a feed peristaltic pump for a high-speed centrifuge. Background Technology

[0002] Peristaltic pumps typically include a drive motor connected via a gearbox to drive a rotor housed in the pump head. This rotor carries a pair of molds or other devices for engagement with a flexible tubing. Peristaltic pumps pump fluid by alternately squeezing and releasing the pump's flexible delivery tubing. They are commonly used for liquid metering and filling. Their operating principle generally involves rotating squeeze rollers to push the liquid forward within the flexible delivery tubing, creating a negative pressure at the rear end of the tubing. This draws the liquid into the tubing, where it is further propelled forward by subsequent squeeze rollers, thus metering the liquid.

[0003] However, most existing peristaltic pumps currently use multiple rollers to squeeze the hose to deliver fluid. During the process of roller friction squeezing the hose, the contact between the roller and the hose is intermittent. After the roller separates from the hose, the roller stops rotating. When it contacts the hose again, the roller is relatively stationary, which will generate a large impact and friction on both the hose and the roller. This will cause the hose to be easily damaged and need to be replaced frequently. The impact on the roller will also affect the accuracy of the peristaltic pump. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a peristaltic pump for feeding high-speed centrifuges.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A peristaltic pump for a high-speed centrifuge includes a first limiting frame, a first hose, a first rotor, and a plurality of first pressure rollers. The inner wall of the first limiting frame is provided with a feeding channel, and the first hose is disposed in the feeding channel. The first rotor is disposed in the middle of the first limiting frame, and the two ends of the first rotor are provided with first mounting plates. The first mounting plates are evenly provided with a plurality of first mounting grooves, and the first mounting grooves are provided with first support blocks. The two ends of the first pressure rollers are connected to the first support blocks. The end of the first support block near the first pressure rollers is provided with a second mounting groove, and the two ends of the first pressure rollers are provided with first rollers. The first rollers are provided with first annular grooves, and the second mounting grooves are provided with a plurality of second rollers, the second rollers matching the first annular grooves.

[0007] Furthermore, the first mounting groove has a first T-slot at both ends, the first support block has a first mounting hole at both ends, the first mounting hole corresponds to the first T-slot, the first mounting hole has a first threaded sleeve that matches the first T-slot, and the first mounting hole has a first threaded rod that corresponds to the first threaded sleeve.

[0008] Furthermore, a first baffle is provided at the end of the first threaded sleeve away from the first pressure roller, and the first baffle matches the first T-slot. A second baffle is provided at the end of the first threaded rod near the first pressure roller, and the second baffle matches the first mounting hole.

[0009] Furthermore, a second turntable is provided in the middle of the first rotor, and a plurality of first support frames are provided on the second turntable. The first support frames are evenly arranged between the first pressure rollers, and a third roller is provided on the first support frame. The third roller is provided with a second annular groove, and the second annular groove matches the first hose.

[0010] Furthermore, the feed peristaltic pump for the high-speed centrifuge includes a first housing, a first limiting frame disposed inside the first housing, a first rotor disposed on the first housing via bearings, and the two ends of the first hose passing through the first housing and disposed on the outside of the first housing.

[0011] The present invention discloses a peristaltic pump for feeding a high-speed centrifuge. Compared with the prior art, its advantages are that it can avoid the first pressure roller from squeezing the first hose by dragging, but instead achieve feeding by rolling and squeezing the first hose, and the third roller can hold the first hose to prevent it from falling off.

[0022] Preferred embodiment.

[0023] This embodiment provides a peristaltic pump for feeding a high-speed centrifuge, including a first limiting frame 110, a first hose 120, a first rotor 130, and a plurality of first pressure rollers 160. The inner wall of the first limiting frame 110 is provided with a feeding channel 111, the first hose 120 is disposed in the feeding channel 111, the first rotor 130 is disposed in the middle of the first limiting frame 110, and the two ends of the first rotor 130 are provided with first mounting plates 140. The first mounting plates 140 are evenly provided with a plurality of first mounting grooves 141, and the first mounting grooves 141 are provided with first support blocks 170. The two ends of the first pressure rollers 160 are connected to the first support blocks 170. The end of the first support block 170 near the first pressure rollers 160 is provided with a second mounting groove 172, and the two ends of the first pressure rollers 160 are provided with first rollers 161. The first rollers 161 are provided with first annular grooves 162, and the second mounting grooves 172 are provided with a plurality of second rollers 173, the second rollers 173 being matched with the first annular grooves 162.

[0024] Furthermore, the first mounting groove 141 has a first T-slot 142 at both ends, and the first support block 170 has a first mounting hole 171 at both ends. The first mounting hole 171 corresponds to the first T-slot 142. The first mounting hole 171 has a first threaded sleeve 180 inside, which matches the first T-slot 142. The first mounting hole 171 has a first threaded rod 190 inside, which corresponds one-to-one with the first threaded sleeve 180.

[0025] Furthermore, the first threaded sleeve 180 is provided with a first baffle 181 at the end away from the first pressure roller 160, and the first baffle 181 matches the first T-slot 142. The first threaded rod 190 is provided with a second baffle 191 at the end near the first pressure roller 160, and the second baffle 191 matches the first mounting hole 171.

[0026] Furthermore, a second turntable is provided in the middle of the first rotor 130, and a plurality of first support frames 151 are provided on the second turntable. The first support frames 151 are evenly arranged between the first pressure rollers 160.

The second mounting plate 150 drives the third roller 152 to rotate. The third roller 152 can abut against the surface of the first hose 120, thereby preventing the first hose 120 from falling off and from being squeezed. The rotation of the first mounting plate 140 drives the first pressure roller 160 to rotate, thereby squeezing the first hose 120 to achieve feeding. Furthermore, the second roller 173 supports the first roller 161, and thus supports the first pressure roller 160. The second roller 173 ensures the rotation of the first roller 161, avoiding pulling and squeezing between the first pressure roller 160 and the first hose 120, and instead uses rolling squeezing, which can protect the first hose 120.
