The material pushing and sorting mechanism 5 is provided with a material distributing pneumatic push plate device, and the pneumatic push plate device realizes the analysis function of a single drill point type bar by receiving the signal transmitted by the electrical control mechanism 1. The material pushing and sorting mechanism 5 can judge whether the V-shaped PE material channel 44 of the linear vibration feeding mechanism 4 is filled with materials by matching with a counter sensing device of the linear vibration feeding mechanism 4, and when the collected information judges that no material is filled in the V-shaped PE material channel 44, the material pushing and sorting action is carried out; when the collected information judges that the V-shaped PE material channel 44 is filled with the materials, the material channel counting sensor 43 counts the bars, and by the method, the products can be sequentially and repeatedly sent to the centerless grinder one by one for processing.

The working principle of the present invention is explained as follows:

the invention connects the whole body to the centerless grinder through the machine tool connecting plate 22 in the main body connecting and protecting mechanism 2. The main body connection protection mechanism 2 is connected with the storage hopper mechanism 3 through a hopper supporting seat 23, and meanwhile, the relative position of the storage hopper and the material pushing and sorting mechanism 5 is adjusted through a hopper level adjusting plate 36; meanwhile, the relative position of the V-shaped PE material channel 44 and the centerless grinding feed inlet is controlled by adjusting the V-shaped material channel vertical adjusting nut 35, and the product is placed in the storage hopper mechanism 3; through adjusting the adjusting nut on the hopper adjusting partition fixing seat 33, the hopper adjusting partition 34 can be pulled to displace, so that the length control and switching of products with different lengths are realized. In the storage hopper mechanism 3, with the movement of the material pushing and sorting cylinder 31, a single product is pushed out from the hopper, and due to the light weight characteristic of the product, the blowing device 51 can blow the product to the V-shaped PE material channel 44; at this time, the products are fed into the centerless grinder one by one to be processed with the vibration of the linear vibrator 41 in a rhythm of frequency. Then, the clearance between the feeding check block 42 and the V-shaped PE material channel 44 in the linear vibration feeding mechanism 4 is adjusted to control the outer diameter of the fed material and the bending condition of the fed material. At this time, if there is a product in the V-shaped PE channel 44, the channel counting sensor 43 sends a signal to the electrical control mechanism 1, and the count is increased by one; if no material exists in the V-shaped PE material channel 44, the electric control mechanism 1 controls the material pushing and sorting mechanism 5 through the electromagnetic valve to continue feeding; the continuous automatic feeding can be realized by reciprocating. In the working process of the invention, the main body water receiving tray 21, the V-shaped material channel water receiving protection 26 and the water collecting tray 27 can effectively collect the grinding fluid of each part in the processing and grinding process, and prevent the grinding fluid from splashing. Meanwhile, the plum blossom-shaped handle 24 is adjusted by adjusting the hopper on the plum blossom-shaped handle seat, so that the gap of the hopper storage inclined plate 32 between the storage hopper mechanism 3 and the pushing and sorting mechanism 5 can be quickly and conveniently adjusted, the hopper horizontal adjusting plate 36 can move along with the gap by adjusting the horizontal adjusting valve 29, and the feeding of products with different outer diameters can be switched. The main body of the whole feeder is supported on the basis of the main body square tube 28, so that the feeder is convenient to install and relatively low in cost.
