Description

Flour conveying and adjusting device Technical Field The utility model relates to the technical field of flour conveying equipment, in particular to a flour conveying and adjusting device. Background Flour production is a complex process with multiple links in cooperation, and involves core processes of grinding, screening, mixing, conveying, packaging and the like. Wherein, powder conveying equipment is used as an artery for connecting all links, and directly influences production efficiency, product quality and safety. At present, the main conveying technology in industry mainly comprises a mechanical conveying technology and a pneumatic conveying technology, wherein the mechanical conveying technology is represented by a screw conveyor (auger), and the powder is pushed to move along a pipeline by rotating a screw blade, so that the pneumatic conveying technology has the characteristics of simple structure, low cost, good sealing performance and the like, and the pneumatic conveying technology realizes powder conveying by utilizing negative pressure or positive pressure formed by air flow in a closed pipeline and can be divided into dilute phase conveying, dense phase conveying and super dense phase conveying. Although the technology satisfies the production demand to a certain extent, along with the development of flour processing scale and intellectualization, the inherent defect of the technology is increasingly prominent, the China patent with the application number of 2021204242448 discloses an automatic intelligent anti-blocking system for flour packing, through the arrangement of a PLC control system, the PLC control system is electrically connected with a flour discharging switch, the PLC control system is controlled to be connected with a variable frequency motor, so that the speed of flour conveying by a screw conveyor can be correspondingly adjusted according to the packing operation speed of packing workers, the blockage of a flour conveying channel is effectively avoided, through the arrangement of a resistance type film pressure sensor, when the pressure of the resistance type film pressure sensor is increased to a set value of the PLC control system, the PLC control system can control the variable frequency motor to stop running, the blockage of the flour conveying channel is avoided to a certain extent, but when the production equipment which is actually assembled runs, due to the monitoring of a single pressure sensor, and no corresponding buffer device is arranged between the screw conveyor and the pipeline connection, the accurate identification of the blockage cannot be realized, the pipeline is required to be disassembled manually in the clear process of blocking. Disclosure of utility model The utility model aims to provide a flour conveying and adjusting device, which is characterized in that an adjusting buffer device is arranged on a conveying device, so that the manual blockage removal can be facilitated, a material level sensor and a displacement sensor are additionally arranged on the conveying device, the accurate blockage identification capability and the sensitivity of monitoring and early warning are improved, and the problems in the prior art are solved. In order to achieve the above purpose, the utility model is realized by adopting the following technical scheme: The utility model provides a flour carries adjusting device, includes the frame, establishes the control unit in frame one side, establishes auger conveyor in the frame and with auger conveyor's discharge end intercommunication's material pipe, auger conveyor and material pipe junction are equipped with the closure plate, closure plate passes through elastic reset subassembly and auger conveyor end connection that corresponds, auger conveyor goes up the inside material level sensor that is equipped with of one end that corresponds the material pipe, auger conveyor lateral wall is equipped with displacement sensor. Further, the elastic reset component comprises a plurality of sleeves arranged on the sealing plate, a plurality of guide rods arranged on the wall of the auger delivery device and penetrating through the corresponding sleeves, and elastic pieces arranged in the corresponding sleeves, each elastic piece is sleeved outside the corresponding guide rod, a limit cap is arranged at one end, close to the sleeve, of each guide rod, one end of each elastic piece is in butt joint with the inner wall of the sleeve, and the other end of each elastic piece is in butt joint with the limit cap. Furthermore, the sealing plate is a prototype thick plate, and the sleeves are uniformly distributed on the outer circle end surface of the sealing plate along the circle center direction of the sealing plate. Further, the displacement sensor is a linear displacement sensor, a sizing component of the linear displacement sensor is arranged on the pipe wall of the auger conveying device, a reading head of the linear displacemen
