The motor drives the reduction box to drive the square tube sorting shaft to rotate along the direction of the square tube movement trend, and the length, width and depth of the groove on the square tube sorting wheel are slightly larger than the length, width and height of the square tube. When the square tubes move to the front end of the square tube sorting wheel from the front end stepping conveyor belt, most square tubes are forced to be temporarily retained at the front end of the square tube sorting wheel due to the blockage of the square tube sorting wheel. Meanwhile, one to two square pipes can move to the grooves on the square pipe sorting wheels due to the gravitational potential energy of the square pipes. Through solid works finite element analysis, when the square tube sorting wheel moves, only one square tube can move to the lower end of the square tube sorting wheel through the sorting tube part of the square tube sorting wheel, and therefore the purpose of square tube sorting is achieved.

In the invention, the length of the plate-pipe groove is 1800mm, the width of the plate-pipe groove is 30mm, a certain movement allowance is provided for the square pipe with the width of 10mm, the movement allowance is used for ensuring that the square pipe can rapidly move on the basis of small friction, and the limiting plate with the upright front end not only plays the role of preventing the square pipe from being thrown out of the installation range due to the gliding speed, but also can ensure that the square pipe can vertically fall into the square pipe plate-pipe groove together with the design of the gliding arc bending section. In order to simplify the design unit of the machine, a movable pipe connecting piece is adopted for positioning and conveying the square pipe, and the pipe connecting piece is used for moving a pipe plate groove for placing and positioning the pipe. The principle is mainly as follows: the motor drives the pipe connecting piece to realize the front and back translation, the translation speed is fast each time, and the translation length is slightly larger than the width of a square pipe. Be equipped with weighing transducer inside the board tube seat, when dropping a square pipe down, the motor can drive the board tube seat on the connecting pipe fitting to the board tube seat direction motion of no square pipe under the transformation of the signal of telecommunication. Thereby realizing the filling function of the bidirectional square tube in one direction.

And after two square pipes drop into the plate pipe groove, the signals are transmitted to the motor under the action of the gravity sensor, so that the reset function of the square pipe connecting piece is realized, and the next group of square pipes to be processed is waited for positioning. The design is mainly characterized in that the signal transmission function between the sensor and the motor is realized, and the movement of the square tube plate tube slot is realized under the action of the sensor, so that the function of positioning the square tube is realized.

When the electric push rod 51 extends for too long, the electric push rod 51 is easy to shake, so that the pipe pushing process is unstable, the electric push rod 51 is adopted to push half of the length of the square pipe, and the electric push rod 51 is adopted to accelerate the pushing mode, so that the square pipe moves forwards continuously under the action of self inertia force after being pushed to half of the length, the whole length of the equipment is shortened, energy is saved, and the cost is reduced. The cross bar 52 is arranged to push the two square pipes simultaneously, and also to align the two square pipes, so as to ensure the alignment of the riveting holes at the back.

Because the length dimension of square pipe is great, and the cross section is the rectangle irregular, and the square pipe number of once impelling processing is two, so general pushing mechanism can't satisfy the demand that we designed. Considering the greater risk of using pneumatic cylinder propulsion. So we improve here, use the electric push rod, in the middle of the electric push rod, add a horizontal pole. The tail end of the cross rod penetrates through the plate pipe groove so as to facilitate the simultaneous propulsion of the two square pipes. Because the stroke of the electric push rod is limited, the stroke of the electric push rod can not exceed one meter, otherwise, the electric push rod is unstable. The potential safety hazard is easily caused, so that only half of the length of the square tube is pushed in the stroke design of the electric push rod, and the stroke limit theoretical value of the electric push rod is not reached.

Under the effect of gravity sensor, the square pipe pushes two square pipes to move forward in an accelerated manner, and after the electric push rod reaches the designed stroke.
