Description

Technical Field

[0001] This utility model relates to the field of grinding head production technology, specifically to a grinding head production screening device. Background Technology

[0002] A grinding head is a general term for a small, shanked grinding tool used in electric grinders, pendant grinders, and hand drills. There are many types, including ceramic grinding heads, rubber grinding heads, diamond grinding heads, and abrasive cloth grinding heads. Ceramic grinding heads: The abrasive grains (generally brown corundum, white corundum, chromium corundum, or silicon carbide) are sintered from a ceramic binder, with a metal shank in the center. They are mainly used for grinding various metals, for grinding the inner walls of holes, and for mold correction.

[0003] In the production of existing ceramic grinding heads, a grinding head rod needs to be installed on the grinding head. When installing the grinding head rod, a vibratory feeder is generally used for feeding. However, after the existing vibratory feeder feeds the material, the discharge direction of the grinding head is uncertain. If the end with the rod groove does not face the direction of the subsequent rod installation, it can easily affect the efficiency and effect of subsequent processing. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the production of existing ceramic grinding heads, the discharge direction of the grinding head is uncertain after the material is fed by the vibratory plate, which easily affects the efficiency and effect of subsequent processing.

The inlet of the discharging guide rail is located on the right side below the outlet of the feeding guide rail, and the inlet of the return guide rail is located on the side of the outlet of the feeding guide rail.

[0008] The screening assembly includes a support and a swing arm rotatably connected to the support. A pendulum is fixedly connected to the lower end of the swing arm, and a limiting rod corresponding to the grinding head groove of the grinding head is fixedly connected to the end of the pendulum facing the outlet of the feeding guide rail.

[0009] A further improvement is that the support includes a column and a crossbeam fixedly connected to the column, and the upper end of the swing arm is rotatably connected to the crossbeam.

[0010] A further improvement is that the upper end of the swing arm is rotatably connected to the crossbeam via a pivot.

[0011] A further improvement is that a nut is fixedly connected to the upper end of the swing arm, and bolts are installed on the crossbeam. The swing arm is rotatably connected to the crossbeam by the nut and the bolts.

[0012] A further improvement is that the outlet of the feeding guide rail is provided with a feeding inclined rail that slopes downward toward the outlet of the discharging guide rail.

[0013] A further improvement is that the inlet of the discharge guide rail is provided with a discharge inclined rail that is inclined in the direction of the outlet of the upward discharge guide rail.

Detailed Implementation

[0024] See Figures 1-5As shown, the technical solution adopted in this specific embodiment is: a mill head production screening device, characterized in that: it includes a vibrating disk body 1 and a screening component for screening materials disposed on the upper end of one side wall of the vibrating disk body 1;

[0025] The vibratory feeder body 1 includes a feeding guide rail 2, a discharging guide rail 3, and a return guide rail 4. The inlet of the discharging guide rail 3 is located below the outlet of the feeding guide rail 2 on the right side, and the inlet of the return guide rail 4 is located on the side of the outlet of the feeding guide rail 2.

[0026] The screening assembly includes a support and a swing rod 7 rotatably connected to the support. A pendulum 8 is fixedly connected to the lower end of the swing rod 7. A limiting rod 9 corresponding to the grinding head groove 51 of the grinding head 5 is fixedly connected to the end of the pendulum 8 facing the outlet of the feeding guide rail 2.

[0027] The support includes a column 6 and a crossbeam 61 fixedly connected to the column 6, and the upper end of the swing rod 7 is rotatably connected to the crossbeam 61.

[0028] The upper end of the swing arm 7 is rotatably connected to the crossbeam 61 via the rotating shaft 10.

[0029] The upper end of the swing arm 7 is fixedly connected to a nut 11, and a bolt 12 is installed on the crossbeam 61. The swing arm 7 is rotatably connected to the crossbeam 61 by the nut 11 and the bolt 12.

[0030] The outlet of the feeding guide rail 2 is provided with a feeding inclined rail 21 that slopes downward toward the outlet of the discharging guide rail 3.

[0031] The discharge guide rail 3 is provided with a discharge inclined rail 31 that is inclined in the direction of the outlet of the upward feeding guide rail 2 at its inlet.

[0032] The inlet of the return guide rail 4 is provided with a return inclined rail 41 that is inclined in the direction of the outlet of the upward guide rail 2.

[0033] The working principle of this utility model is as follows: During use, the vibrating disc vibrates to feed the material. The grinding head passes through the feeding guide rail to the feeding inclined rail. When the grinding head rod groove 51 of the grinding head faces the outlet direction of the feeding inclined rail, the limiting rod of the pendulum will be inserted into the grinding head rod groove 51. When the grinding head is fed, it is blocked by the limiting rod and rises to a certain angle. Then it will fall into the discharge inclined rail and then follow the discharge guide rail to discharge the material. When the grinding head rod groove 51 of the grinding head faces away from the outlet direction of the feeding inclined rail, the grinding head will push the pendulum forward when it is fed. Then it will fall into the return inclined rail and then feed the material again along the return guide rail. This can realize the screening of the grinding head and ensure the discharge direction of the grinding head rod groove 51.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions provided are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
