Problems solved by technology

In the process of continuous squeezing of the hose by the roller, the pipeline is severely deformed and worn, resulting in a short service life of the hose; and the deformation of the hose also makes it difficult for the precision stability of the peristaltic pump to meet the production requirements
In addition, because the hose is not completely fixed and positioned in the pump body, it is easy to drive the hose to move when the roller rotates, resulting in precision errors
The above problems have caused the accuracy and stability of the existing peristaltic pumps to be low, which limits the application range of peristaltic pumps to a certain extent.

Embodiment 1

[0029] Such as figure 1 and figure 2 As shown, a linear moving tube peristaltic pump of the present invention includes: a pump body assembly, a pipeline assembly, a shut-off assembly, a pressure tube assembly and at least one set of linear reciprocating components; the shut-off assembly is used to clamp and loosen the tube The linear reciprocating motion assembly and the pressure tube assembly are installed on the pump body assembly; the pipeline assembly is connected with the linear reciprocating motion assembly, and the pipeline assembly follows the reciprocating motion of the linear reciprocating motion assembly; the pressure tube assembly Squeeze the reciprocating pipeline components to complete the pumping and metering of materials.

[0030] In this embodiment, both the linear reciprocating assembly and the pressure tube assembly are installed on the pump body assembly; the pipeline assembly is connected to the linear reciprocating assembly, and the pipeline assembly re...

Embodiment 2

[0042] Such as image 3 and Figure 4 As shown, the structure and working principle of the linear moving tube peristaltic pump of the present invention are roughly the same as those of the linear moving tube peristaltic pump in Embodiment 1, the difference is that the pressure tube assembly is arranged on the bracket 10 through the mounting plate 19 The outer side, that is, the bracket 10 and the pressure tube assembly are located on different sides of the elastic hose 11 . In this embodiment, by arranging the bracket 10 and the pressure tube assembly on different sides of the elastic hose 11, the installation volume of the bracket 10 is reduced, and the lateral distance between the bracket 10 and the elastic hose 11 is also shortened, which is beneficial Improving the transmission stability between the bracket 10 and the elastic hose 11 is also beneficial to reducing the overall installation volume of the peristaltic pump.

Embodiment 3

[0044] Such as Figure 5 As shown, a linear moving tube peristaltic pump of the present invention has substantially the same structure and working principle as the linear moving tube peristaltic pump in Embodiment 1, the difference is that the pump body assembly includes a pump body baffle 20; The linear reciprocating motion assembly includes a first driving power part 1 and a lead screw 6; one end of the lead screw 6 is connected to the output end of the first driving power part 1 through a coupling 2, and the other end of the lead screw 6 is connected to the pump body baffle 20 connect. The lead screw 6 is provided with a lead screw nut 4 , and with the rotation of the lead screw 6 , the lead screw nut 4 reciprocates on the lead screw 6 ; the lead screw nut 4 is provided with a pipe joint clamping plate 16 .

[0045] Further, a bearing is provided at the joint between the lead screw 6 and the pump body baffle 20 , and the transmission stability of the lead screw 6 is improv...

Abstract

The invention discloses a linear type movable pipe peristaltic pump. The linear type movable pipe peristaltic pump comprises a pump body assembly, a pipeline assembly, a closure assembly, a pipe pressing assembly and at least one linear reciprocating motion assembly, wherein the closure assembly is used for clamping and loosening the pipeline assembly; the linear reciprocating motion assemblies and the pipe pressing assembly are both installed on the pump body assembly; the pipeline assembly is connected with the linear reciprocating motion assemblies; along with reciprocating motion of the linear reciprocating motion assemblies, the pipeline assembly conducts reciprocating motion; and the pipe pressing assembly extrudes the pipeline assembly conducting reciprocating motion, and thereforematerial pumping metering is completed. The linear type movable pipe peristaltic pump has the beneficial effects that the structure is simple, the service life of an elastic hose is long, the fillingefficiency is high, and the metering precision is stable.

Description

technical field [0001] The invention mainly relates to the technical field of fluid filling pumps, in particular to a linear moving tube peristaltic pump. Background technique [0002] At present, the multi-position mechanical filling pumps used in the field of fluid filling include plunger pumps, peristaltic pumps, syringe pumps and the like. Among them, peristaltic pumps are widely used in various industries due to their advantages of no pollution and better accuracy, including chemical industry, pharmaceutical industry, food filling industry and so on. In order to meet the high requirements of fluid filling in terms of accuracy and stability, it is necessary to continuously squeeze the pump tube through the roller during the operation of the peristaltic pump, just like pinching the hose with two fingers, the roller squeezes the hose and Rotate, two chambers of positive pressure and negative pressure are formed in the hose, and the liquid flows out accordingly. In the pr...
