The invention discloses a popping bead
strength testing instrument which comprises a case.The case is provided with a controller and a feeding pressurizing mechanism.The feeding pressurizing mechanism comprises a material
barrel, a carrying table, a pressure head, a compressing mechanism and a compressing motor, wherein the pressure head is fixed to the compressing end of the compressing mechanism, and the compressing motor is in driving connection with the compressing mechanism.The carrying table comprises a carrying table support, and the carrying table support is provided with an air blowing
pipe, a pressure-bearing head, a
pressure sensor and a steel wire groove, wherein the pressure-bearing head is in rigid connection with the
pressure sensor, one end of the pressure head right faces the pressure-bearing head, a
grating ruler is connected to the other end of the pressure head, the steel wire groove is located between the pressure-bearing head and the pressure head, a discharging port of the material
barrel is provided with a flexible material guide
pipe, an air blowing opening of the air blowing
pipe faces the steel wire groove, a popping bead
detector is arranged in a pipeline of the material guide pipe, and the
pressure sensor, the
grating ruler and the popping bead
detector are electrically connected with the controller.The popping bead
strength testing instrument is capable of saving manpower and high in efficiency, the discharging process is simple, the material
barrel can be quickly replaced to be compatible to samples with different diameters, and material jamming and residual materials can be avoided.
