Description

High-precision tray blanking type longitudinal anti-tearing device Technical Field The utility model relates to the technical field of anti-tearing devices, in particular to a blanking type longitudinal anti-tearing device of a high-precision tray. Background In the process of conveying materials, the problems of perforation, tearing, breakage and the like of the belt caused by some factors are unavoidable, so that serious influence is brought to production, meanwhile, because the value of the belt is higher, the damage and leakage of the belt are found as early as possible, and a timely shutdown strategy is adopted, so that the damage of the belt is avoided, and the damage and influence caused by accidents are avoided to be further enlarged. The traditional tearing-proof device adopts a pull rope type tearing-proof device, but the situation that some situations do not occur actions can not be responded to various tearing situations. Disclosure of utility model In order to solve the technical problems, the utility model provides the high-precision tray blanking type longitudinal anti-tearing device which adopts the design thought of variable torque in action, can not automatically reset once the action is triggered, and has the characteristics of high precision, high reliability and vibration resistance. The utility model relates to a blanking type longitudinal anti-tearing device of a high-precision tray, which comprises a frame and shaft seats, wherein both groups of shaft seats are arranged on the outer side wall of the frame; the device also comprises a limiting device, a detecting device, a screen plate, a baffle, a touch rod and a contact sensor, wherein the screen plate is inclined and rotatably arranged on the two groups of shaft seats, the baffle is arranged on the outer side wall of the lower end of the screen plate, the touch rod is arranged on the outer side wall of the lower end of the screen plate, the touch sensor is arranged on the outer side wall of the frame, corresponds to the position of the touch rod, is arranged on the outer side wall of the higher end of the screen plate, is used for supporting and limiting the higher end of the screen plate, is arranged on the frame, and is used for detecting broken or puncture foreign matters of the belt; the frame is arranged below the belt, the lower end of the screen plate faces the conveying direction of the belt, when the belt runs, dust can fall from the screen of the screen plate, if large leakage occurs, particles with the diameter larger than 4mm are gathered on the screen plate on one side of the baffle plate, after the weight exceeds a set weight, the screen plate rotates around the shaft seat and drives the touch rod to move downwards, the touch rod presses the detection end of the touch sensor after moving downwards, so as to trigger the touch sensor to change the output state, the belt is triggered to stop, when the belt breaks, the belt part disperses and falls down to trigger the detection device, the detection device presses the detection end of the touch sensor, so as to trigger the belt to stop, when the fault is processed, the detection device resets when the material on the screen plate is required to be cleaned, the screen plate is overturned backwards, the touch rod moves upwards to reset, the device resumes the monitoring working mode again, the device adopts the design idea of changing torque, once the action is triggered, the automatic reset is avoided, and the device has the characteristics of high precision, high reliability and vibration resistance. Preferably, the detection device comprises a support arm, a rotating arm and a cross rod swinging arm, wherein the bottom end of the support arm is connected with the outer side wall of the frame, the rotating arm is rotatably arranged at the top end of the support arm, the cross rod swinging arm is arranged at the top end of the rotating arm, the support arm and the rotating arm are in a vertical angle in an initial state, after a belt breaks, the weight of the belt presses the cross rod swinging arm to enable the rotating arm to overturn forwards, so that the rotating arm presses the detection end of the contact sensor to trigger the belt to stop, and meanwhile, after a puncture foreign matter exists on the belt, the foreign matter is enabled to stir the cross rod swinging arm forwards in the belt conveying process, so that the rotating arm overturns forwards to trigger the belt to stop, and loss is reduced. The bottom end of the limiting frame is contacted with the outer side wall of the frame to support the higher end of the screen plate in an initial state, and when the screen plate is turned forwards, the screen plate drives the limiting frame to move upwards to be separated from the frame, so that the limiting frame is convenient to support and limit the higher end of the screen plate, and the inclination angle of the screen plate is convenient to guarantee.
