[0003] Unqualified blanks will be produced in the production of pulleys, and the selection of various indicators and materials of pulleys is based on the principle of minimizing raw materials, feasible processes, and lowest costs while meeting the requirements of use. Therefore, large-sized unqualified blanks will be processed into small-sized pulleys. In the traditional pulley blank processing process, the blanks will be screened by the detection mechanism to determine whether they are qualified or not.

The piston rod end of the telescopic cylinder is fixedly connected to a connector, and an axial rod penetrating the elongated hole is vertically fixedly connected to the connector. When the detection mechanism detects that the material is unqualified, the piston rod of the telescopic cylinder extends into place, and the end of the L-shaped material blocking member located on the conveyor belt is tilted from the hinge to the unqualified blank discharge port and connected to the unqualified blank discharge port, and cooperates with the conveying mechanism to guide and convey the unqualified blank, so that the unqualified blank can be smoothly discharged without affecting the conveying of other blanks, thereby ensuring a practical effect.
[0021] 3) The utility model is provided with a buffering guide mechanism for connecting the material collection frame at the unqualified blank discharge port. The buffering guide mechanism includes a group of upper slide members and lower slide members that are sleeved and slidably connected.

Both sides of the lower slide member are provided with corresponding small-rigidity elastic members between the upper slide member, and the upper surface thereof is tilted downwardly and fixedly connected with a corresponding material guide plate at the end that is not connected to the upper slide member. Generally, the inclined plate used for material guidance should not be too long. If the material is too long, the material will be stuck on the inclined plate due to friction. Moreover, the required material collection frame is shorter, and the material collection frame needs to be replaced frequently due to the small number of blanks held. In addition, a customized material collection frame with a lower height needs to be used. If the inclined plate is not long enough, the material discharge height is too high, and the material discharge is prone to local depression and deformation problems, which affects the reuse rate and increases the unqualified rate. The utility model adds a buffer guide mechanism with adjustable length. The length of the upper slide chute is shorter, ensuring that the sliding force of unqualified blanks is greater than the friction force, so that the upper slide chute not only plays the role of guiding materials but also can fix the lower slide chute. The blank slides to the lower slide chute and hits the guide plate. At this time, the lower slide chute moves downward, and the small rigidity elastic part is stretched, shortening the distance between the blank and the collection frame. The falling height of the blank is reduced, thereby effectively solving the problem of local depression caused by the high falling height. After the blank is discharged, the small rigidity elastic part resets and drives the lower slide chute to reset. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0028] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:
[0029] refer to Figure 1-5 , a blank screening mechanism for pulley processing, comprising:
[0030] A conveying mechanism 1, wherein a qualified blank discharge port 2 and an unqualified blank discharge port 3 are respectively provided at the end and the middle side of the conveying mechanism 1;

[0033] The buffer guide mechanism 6 is arranged at the unqualified blank discharge port 3 of the conveying mechanism 1, and is used for conveying unqualified blanks and adjusting the descending height of unqualified blanks; the buffer guide mechanism 6 comprises a group of upper slide members 601 and lower slide members 602 which are sleeved and slidably connected up and down, the upper slide member 601 is tilted and fixedly installed on the support frame 7 corresponding to the unqualified blank discharge port 3, both sides of the lower slide member 602 are provided with corresponding small rigidity elastic members 603 between the upper slide member 601, and the upper surface thereof is tilted downwardly fixedly connected with a corresponding guide plate 604 at the end not connected to the upper slide member 601, when the unqualified blank is discharged to the guide plate 604 along the buffer guide mechanism 6, the small rigidity elastic member 603 is stretched and the lower slide member 602 moves downward;
[0034] The material collecting frame 8 is arranged at the material discharging port of the buffer material guiding mechanism 6 .
[0035] The utility model can not only realize the screening of pulley processing blanks, but also buffer and guide unqualified blanks, effectively reducing the impact force on the unqualified blanks when they fall, thereby reducing or avoiding local deformation of the unqualified blanks due to falling, so that they can be processed into other small-sized blanks, thereby improving the reuse rate of the pulley blanks and reducing the unqualified rate.
[0036] The utility model is provided with a buffering guide mechanism 6 for connecting the collection frame 8 at the unqualified blank discharge port 3. The buffering guide mechanism 6 comprises a set of upper slide members 601 and lower slide members 602 which are sleeved and slidably connected up and down.
