Description

Technical Field

[0001] This invention belongs to the field of peristaltic pump technology, and specifically discloses a peristaltic pump for use as a filler in cosmetic production. Background Technology

[0002] Peristaltic pumps, as a common fluid transport device, are widely used in the cosmetics manufacturing industry for the precise delivery of various fillers, additives, and fluids. They achieve fluid transport by periodically squeezing a flexible tube with a drive wheel, creating a peristaltic effect. They offer advantages such as hygiene, ease of cleaning, and the ability to transport sensitive fluids.

[0003] In existing technologies, peristaltic pumps used in cosmetic production typically employ a single flexible hose for delivery. During continuous production, the hose is prone to wear due to prolonged compression and friction, leading to changes in its inner diameter and decreased elasticity. This, in turn, causes reduced flow accuracy and unstable delivery. When the hose wears down to the point of needing replacement, the pump body or related structures must be disassembled to replace the hose. This not only causes production interruptions and affects efficiency, but also, in some continuous or sterile production environments, frequent shutdowns increase the risk of contamination and process fluctuations.

[0004] Therefore, those skilled in the art have proposed a peristaltic pump for use as a filler in cosmetic production to solve the problems mentioned above. Summary of the Invention

[0012] In the above technical solution, preferably, the driving assembly further includes two driving shells, one of which has two ends that pass through two second mounting plates, and the other driving shell has two ends that pass through two first mounting plates. A fixing ring is provided between the two driving shells and is fixedly connected to the inner wall of the mounting shell. One end of the driving shell is rotatably connected to one end of the fixing ring.

[0013] In the above technical solution, preferably, the output shaft of the motor is fixedly connected to a rotating shaft, the other end of the rotating shaft passes through one of the drive housings, the fixing ring and the other drive housing in sequence, and the diameter of the rotating shaft is smaller than the inner diameter of the drive housing, and a connecting plate is fixedly connected to the inner wall of the drive housing.

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0033] like Figures 1-10The peristaltic pump for cosmetic production fillers shown includes a mounting housing 1, a cover 101 detachably mounted on one side of the mounting housing 1, a motor 2 mounted on the other side of the mounting housing 1, a drive assembly 5 mounted inside the mounting housing 1, a second hose 301 inside the mounting housing 1 with both ends extending out of the mounting housing 1, an installation cavity on the side of the mounting housing 1 away from the motor 2, a first hose 3 inside the installation cavity with both ends extending out of the installation cavity, a cover 101 for covering the installation cavity, a snap-fit ​​assembly 4 for fixing the position of the first hose 3 mounted on the surface of the cover 101 and the mounting housing 1, and a limit bolt 102 mounted on the surface of the cover 101.

[0034] The snap-fit ​​assembly 4 includes a connecting half-ring 401 fixedly connected to the surfaces of the mounting shell 1 and the cover 101. A slot 402 is provided on the inner side of the connecting half-ring 401. A uniformly distributed magnetic strip 403 is fixedly connected inside the slot 402. An installation strip 404 is fixedly connected to the surface of the connecting half-ring 401. A limit hole 405 is provided on the surface of the installation strip 404.

[0035] By starting the motor 2, the drive component 5 can be driven to work, thereby driving the first hose 3 to transport materials. Under normal circumstances, the second hose 301 will not work. When the first hose 3 is worn and needs to be replaced, the limit bolt 102 can be removed to release the limit on the cover 101, and then the cover 101 can be removed to replace the first hose 3. Under the action of the drive component 5, the output of materials can be maintained through the second hose 301 during the replacement process, so as to achieve the purpose of online replacement. The setting of the snap-fit ​​component 4 can improve the installation efficiency of the first hose 3.

[0036] like Figures 1-10 As shown, the snap-fit ​​assembly 4 also includes an adsorption ring 410 fixedly connected to the surface of the first hose 3. The adsorption ring 410 matches the snap-fit ​​groove 402. An installation ring 406 is fixedly connected to the surface of the first hose 3. A pull plate 407 is provided on the side of the installation ring 406 away from the adsorption ring 410. A limit rod 409 is fixedly connected to the surface of the pull plate 407. The other end of the limit rod 409 passes through the installation ring 406 and extends into the interior of the limit hole 405. A return spring 408 is fixedly connected between the pull plate 407 and the installation ring 406.

[0037] Specifically, the adsorption ring 410 is a magnetic material component that can be adsorbed by the magnet strip 403 during installation, thereby improving installation efficiency. After installation, the first hose 3 is initially limited by the cooperation of the slot 402 and the adsorption ring 410. By pulling the pull plate 407, the limiting rod 409 is moved away from the installation strip 404. After the cover 101 is installed, the limiting rod 409 passes through the limiting hole 405 with the assistance of the reset spring 408, which strengthens the connection effect after the two connecting half rings 401 are docked.

[0038] like Figures 1-10 As shown, the drive assembly 5 includes two first mounting plates 501 rotatably connected inside the mounting housing 1. Two second mounting plates 502 are provided inside the mounting cavity. Three drive wheels 503 arranged in a ring are provided between the two first mounting plates 501 and between the two second mounting plates 502. The two sets of drive wheels 503 are in contact with the surfaces of the first hose 3 and the second hose 301, respectively.

[0039] The surface of the second mounting plate 502 is provided with a sliding cavity 517. A slider 516 is slidably connected to the inner wall of the sliding cavity 517. A guide rod 518 is fixedly connected to the inner wall of the sliding cavity 517. The surface of the slider 516 is slidably connected to the surface of the guide rod 518. A second spring 515 is fixedly connected between the surface of the slider 516 and the inner wall of the sliding cavity 517.

[0040] A mounting post 519 is fixedly connected to the side of the sliding cavity 517 away from the center of the second mounting plate 502. A fixing block 520 is fixedly connected to the surface of the mounting post 519. A pressure sensor 521 is embedded in the side of the fixing block 520 near the slider 516. Both ends of a set of drive wheels 503 are rotatably connected to the surface of the adjacent slider 516.

[0041] Specifically, with long-term use, the surface of the first hose 3 will gradually wear down, causing the drive wheel 503 to not make tight contact with the first hose 3, resulting in poor conveying effect. The second spring 515 can push the slider 516 to make the drive wheel 503 stick tightly to the surface of the first hose 3, avoiding the situation where the first hose 3 wears down and the contact is not tight, resulting in poor conveying effect. The elasticity of the second spring 515 is used to compensate for wear. At the same time, under the action of the pressure sensor 521, the pressure generated by the slider 516 driven by the second spring 515 on the pressure sensor 521 exceeds the threshold and a signal is transmitted.

[0042] Furthermore, the peristaltic pump is equipped with a corresponding controller. After receiving the signal transmitted by the pressure sensor 521, the controller can trigger a prompt so that the staff can replace the first hose 3 in a timely manner.

[0043] like Figures 1-10 As shown, the drive assembly 5 also includes two drive housings 504. One drive housing 504 has two ends that pass through two second mounting plates 502 respectively, and the other drive housing 504 has two ends that pass through two first mounting plates 501 respectively. A fixing ring 505 is provided between the two drive housings 504 and is fixedly connected to the inner wall of the mounting housing 1. One end of the drive housing 504 is rotatably connected to one end of the fixing ring 505.

[0044] The output shaft of motor 2 is fixedly connected to a rotating shaft 510. The other end of the rotating shaft 510 passes through one drive housing 504, a fixing ring 505 and another drive housing 504 in sequence. The diameter of the rotating shaft 510 is smaller than the inner diameter of the drive housing 504. A connecting plate 509 is fixedly connected to the inner wall of the drive housing 504.

[0045] The rotating shaft 510 has a liquid storage chamber 513 inside. A fixed shell 512 is fixedly connected to the inner wall of the liquid storage chamber 513. An electric push rod 511 is fixedly connected to the inner wall of the fixed shell 512. The output shaft of the electric push rod 511 passes through the fixed shell 512 and is fixedly connected to a pressing plate 514 that is slidably connected to the inner wall of the liquid storage chamber 513. The liquid storage chamber 513 is filled with hydraulic oil.

[0046] The rotating shaft 510 has two connecting cavities 508 symmetrically distributed around the liquid storage cavity 513. A drive plate 506 is slidably connected to the inner wall of the connecting cavity 508. One end of the drive plate 506 extends through the rotating shaft 510, and the other end of the drive plate 506 is fixedly connected to the inner wall of the connecting cavity 508 with uniformly distributed first springs 507.

[0047] Specifically, when the first hose 3 is not worn, the connecting cavity 508 near the first hose 3 is filled with hydraulic oil, so that the drive plate 506 can push the connecting plate 509 near the first hose 3 to move during the rotation of the rotating shaft 510, and drive the drive housing 504 connected thereto to rotate, thereby driving the second mounting plate 502 to rotate to squeeze the first hose 3.

[0048] When the pressure sensor 521 detects that the pressure exceeds the threshold, it transmits a signal to the electric push rod 511. At this time, the electric push rod 511 drives the extrusion plate 514 to reset. During the reset process, the extrusion plate 514 can squeeze the hydraulic oil inside the storage chamber 513 and inject it into the other connecting chamber 508, causing the other drive plate 506 to extend from the connecting chamber 508. Under the action of the rotating shaft 510, it can drive the other drive housing 504 to rotate, thereby driving the first mounting plate 501 and the corresponding drive wheel 503 to rotate, thus squeezing the second hose 301. Under the action of the second hose 301, the material is conveyed. During this process, the hydraulic oil is squeezed back into the storage chamber 513 for storage due to the reset of the extrusion plate 514. Under the action of the first spring 507, the drive plate 506 near the second mounting plate 502 is reset, so that the second mounting plate 502 will no longer rotate, which is convenient for subsequent replacement.

[0049] Working principle: The second spring 515 pushes the slider 516 to make the drive wheel 503 press tightly against the surface of the first hose 3, preventing poor contact and delivery caused by wear on the surface of the first hose 3. The elasticity of the second spring 515 compensates for wear. Simultaneously, under the action of the pressure sensor 521, when the pressure generated by the slider 516 driven by the second spring 515 exceeds a threshold, a signal is transmitted. When the pressure sensor 521 detects that the pressure exceeds the threshold, it transmits a signal to the electric push rod 511. At this time, the electric push rod 511 drives the squeezing plate 514 to reset. During the reset process, the squeezing plate 514 squeezes the liquid storage chamber 51. Hydraulic oil is injected into another connecting cavity 508, causing another drive plate 506 to extend from the connecting cavity 508. This allows the drive housing 504 to rotate under the action of the rotating shaft 510, which in turn drives the first mounting plate 501 and the corresponding drive wheel 503 to rotate, thus squeezing the second hose 301. This allows the material to be conveyed under the action of the second hose 301. During this process, the hydraulic oil is squeezed back into the storage cavity 513 due to the reset of the squeezing plate 514. Under the action of the first spring 507, the drive plate 506 near the second mounting plate 502 is reset, preventing the second mounting plate 502 from rotating and facilitating subsequent replacement.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
