It should be noted that, in this embodiment, one end of each elastic hose 3 extends out of the pump body for inputting materials, and the other end of each elastic hose 3 passes through the pump body to output materials; the rotating rotor 5 intermittently extrudes each elastic hose 3 by extruding the elastic barrier 4, so that materials are sucked into the hose from one end of each elastic hose 3 and then flow out from the other end of the elastic hose 3. The ports of the flexible hose 3 in and out of the hose pump are correspondingly provided with a closure assembly.

Further, in this embodiment, during the operation of the hose pump, the elastic partition 4 incompletely extrudes the elastic hose 3, and the inner wall of the inner cavity of the elastic hose 3 is not in contact with the inner wall of the inner cavity.

In this embodiment, the elastic tube 3 is limited by the tube groove 21, so that the elastic tube 3 can be prevented from sliding off the mounting base 2. Correspondingly, the elastic partition 4 is of a structure with one horizontal end and a conical step at the other end, the conical structure of the elastic partition 4 is attached to the outer contour of the conical roller 6, deformation of the elastic hose 3 along the horizontal direction in the process of pressing the hose is guaranteed, and precision stability of the hose pump is guaranteed. In order to avoid mutual contact and interference, the bottom of the rotor 5 is also provided with an inclined structure, and the elastic baffle 4 is not in contact with the rotor 5. In the pipe pressing process, the elastic barrier 4 covering the elastic hose 3 is fixed, and only the roller assembly rotates continuously along with the rotor 5, so that the phenomenon that the hose is dislocated due to the fact that the roller assembly extrudes the elastic hose 3 is avoided. Two elastic hoses 3 are simultaneously arranged in the hose groove 21, which is beneficial to improving the working efficiency of the hose pump. It will be appreciated that in order to increase the efficiency of use of the hose pump, it is also conceivable to provide only one flexible hose 3 in the hose groove 21, i.e. to provide the flexible hose 3 around the hose groove 21 in a full turn.

The outline taper of the conical roller 6 can be determined according to the overall size of the hose pump, so that the linear speed of each roller is kept consistent during extrusion. The structure of the elastic separation rail 4 is mutually attached to the outer contour of the conical roller 6, so that the friction loss between the conical roller 6 and the elastic separation rail 4 and between the elastic separation rail 4 and the elastic hose 3 is reduced. In addition, the two elastic hoses 3 are symmetrically arranged in the hose grooves on the two sides of the rotor 3 respectively, the roller extrudes the elastic partition 4 when rotating along with the rotor 3, the two elastic hoses 3 are sequentially and alternately extruded, the working efficiency of the hose pump is improved, sufficient elastic recovery time is provided for the elastic partition 4 and the elastic hoses 3, and the precision stability of the hose pump is improved.

In this embodiment, the two ends of the flexible hose 3 entering and exiting the hose pump are respectively connected to a cut-off assembly (not shown). The shut-off assembly cooperates with the flexible hose 3 to perform the anti-backflow operation. It will be understood that the shut-off assembly can be embodied as a one-way valve or a pinch valve or a solenoid valve, or as an on-off valve, but is not limited to an on-off valve and the above-mentioned valve group, according to the actual requirements.

During operation, the driving assembly 1 drives the rotor 5 to rotate, the conical roller 6 on the side of the rotor 5 rotates while applying pressure to the elastic separation baffle 4, the elastic separation baffle 4 is elastically deformed under the pressure of the conical roller 6, and the elastic hose 3 is incompletely extruded, namely, the inner cavity tube wall of the elastic hose 3 is not contacted. The elastic barrier 4 only deforms to press down the elastic hose 3 and does not rotate along with the conical roller 6, so that the outer pipe wall of the elastic hose 3 is only pressed downwards by the elastic barrier 4 and is not subjected to the rolling friction force of the conical roller 6. The space of the inner cavity of the elastic hose 3 pressed down by the elastic partition 4 is reduced, the pressure of the fluid in the tube cavity is increased, at the moment, the closure assembly at the outlet end of the elastic hose 3 is opened, the fluid in the tube cavity is discharged, and the material conveying is realized. Along with the rotation of the conical roller 6, the elastic partition 4 continuously presses the elastic hose 3, and materials in the pipe cavity are smoothly discharged. When the tapered roller 6 moves to a preset position, the shut-off assembly at the outlet end of the elastic hose 3 is closed, and the shut-off assembly at the inlet end is opened. In the process that the conical roller 6 continuously rotates and gradually loosens the elastic separation rail 4, the elastic separation rail 4 leaves the elastic hose 3 due to the elastic recovery of the elastic hose 3, and meanwhile, the elastic hose 3 increases the space in the tube cavity by means of the elastic recovery of the elastic hose 3 to form negative pressure so as to suck materials. Reciprocating like this, toper gyro wheel 6 lasts the rotation and extrudees elasticity shelves 4, extrudees elastic hose 3 again, realizes lasting material and carries.

In this embodiment, the elastic hose 3 is limited by arranging the inclined hose groove 21 on the outer side of the mounting base 2, and correspondingly, the elastic partition 4 is arranged in a horizontal step shape, so that the elastic hose 3 is extruded along the inclined direction of the hose groove 21 in the hose pressing process, and the precision stability of the hose pump is ensured. Meanwhile, two elastic hoses 3 are symmetrically arranged in the hose groove 21 respectively, so that enough elastic recovery time is provided for the elastic separating barriers 4 and the elastic hoses 3 on the two sides of the rotor 5, and the working efficiency and the precision stability of the hose pump are improved. It will be appreciated that in order to increase the efficiency of use of the hose pump, it is also conceivable to provide only one flexible hose 3 in the hose groove 21, i.e. to provide the flexible hose 3 around the hose groove 21 in a full turn.
