[0015] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0016] As Figs. 1-3The centerless grinder piston rod automatic unloading device is connected downstream of the conveying device 1, and includes a feeding groove 2, the slot of the feeding groove 2 is slightly lower than the conveying belt 3 of the conveying device 1, so that the piston rod falling on the conveying belt 3 can smoothly enter the feeding groove 2, and a control button 4 is fixedly connected to the end of the feeding groove 2 away from the conveying device 1, the control button 4 is set to be powered on for a long time and powered off for returning, the control button 4 is used for controlling the motor of the electric telescopic rod 5, and the motor of the electric telescopic rod 5 is fixedly connected with an electromagnetic brake, the electromagnetic brake is a common brake device, and the tightness of the brake belt is controlled through the electromagnetic principle. When powered on, the electromagnet attracts the brake belt, so that the motor can rotate freely; when powered off, the electromagnet loses magnetism, the brake belt is tightened, and the brake force is generated to make the motor return to the original position. The feeding groove 2 is fixedly connected with a pin shaft 6, the pin shaft 6 is rotatably connected to a mounting seat 7 through a rotating shaft, the mounting seat 7 is fixedly connected to a slide rod 8 or a piston rod of the electric telescopic rod 5, the slide rod 8 is slidably connected in a limiting groove 9, the limiting groove 9 and the rod body of the electric telescopic rod 5 are fixedly connected to a base 10, the base 10 is fixedly connected with a rod collecting groove 11 and a supporting block, and a dust collector 12 is fixedly connected to the supporting block. Through the dust collector 12, the dust on the piston rod is sucked and removed, and the cleanliness of the piston rod in the rod collecting groove 11 is improved.

[0017] The base 10 is provided with a mounting groove 13, and sliding surfaces 14 are formed at the top of the two sides of the mounting groove 13.

[0018] The feeding groove 2 is in a circular arc shape matching the curvature of the piston rod, and is slightly inclined with the upstream being higher and the downstream being lower, and the inclination angle is less than 5 degrees, so that the piston rod can slide to the control button 4, and when the feeding groove 2 transfers the piston rod to the rod collecting groove 11, the piston rod can fall into the groove in a horizontal state. The center of the bottom of the feeding groove 2 is a horizontal surface, and the two ends of the bottom are in a circular arc shape matching the curvature of the sliding surface 14.

[0019] The limiting groove 9 and the electric telescopic rod 5 are installed in the mounting groove 13, the mounting seat 7 connected with the slide rod 8 and the piston rod of the electric telescopic rod 5 is located in the same horizontal and vertical plane, and the horizontal and vertical planes are respectively parallel to the bottom surface and the front and rear side surfaces of the mounting groove 13, and the pin shaft 6 matched with the mounting seat 7 is installed at the position close to the rear side of the horizontal surface of the bottom of the feeding groove 2, so that when the piston rod of the electric telescopic rod 5 moves upward, the feeding groove 2 can rotate towards the rod collecting groove 11.

[0020] The bottom plate of the rod collecting groove 11 is inclined with the front being low and the rear being high, and shock-absorbing rubber 15 is bonded on the inner wall of the front end of the rod collecting groove 11, so that the shock-absorbing rubber 15 can reduce the influence of the force generated by the continuous collision between the piston rods on the front end of the rod collecting groove 11.

[0021] The piston rod falls from the conveying device 1 to the feeding groove 2, and slides and presses the control button 4, so that the electric telescopic rod 5 works, the feeding groove 2 rotates to the direction of the rod collecting groove 11, the piston rod rolls from the feeding groove 2 to the rod collecting groove 11, at this time, the control button 4 resets, under the action of the electromagnetic brake, the motor resets to make the electric telescopic rod 5 reset, finally, the feeding groove 2 resets, and automatic discharging is realized.

[0022] It is obvious for those skilled in the art that the utility model is not limited to the details of the above-mentioned exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the utility model is defined by the appended claims instead of the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model.
