Description

Technical Field

[0001] The invention relates to the field of detonator polishing devices, in particular to an automatic detonator polishing mechanism. Background Art

[0002] After the detonator is assembled, it needs to be tumbled, that is, the detonator and sawdust are mixed in a certain proportion, and then put into the tumbling machine for tumbling. After tumbling, the mixture of detonator and sawdust needs to be poured onto the sieve plate for screening, and finally the sieved detonator is divided into small portions for use in the next process.

[0003] The existing method is to manually pour the detonator into a bag filled with sawdust, then put the bag into a roller machine for rolling, stop the roller machine after a certain period of time, manually take the bag out of the roller machine, put it on the screen plate, untie the rope at the bag mouth, and then indirectly lift the bag tail to pour all the detonators and sawdust onto the screen plate at once, and then indirectly operate the screen plate for screening to separate the detonator and sawdust, and finally use an indirect device to separate the detonators into boxes. Manual rolling of detonators has the following problems: 1. Before rolling, personnel need to manually pour the detonators into the cloth bag. After rolling, personnel need to manually take out the cloth bag and place it on the screening plate. Personnel need to directly operate the product many times, which poses a great safety risk.

[0004] 2. During tumbling, the product and sawdust are placed in a cloth bag, and the cloth bag is rolled in the drum, and the tumbling effect is not high.

The second rotary motion platform 4.1 is embedded and mounted on the mounting surface of the frame 1. The front end of the second rotary motion platform 4.1 has a rotary motion part that can rotate around a rotation center line perpendicular to the mounting surface of the frame 1 along the front and rear horizontal direction.

Then the loading tray 2.2 rotates, so that the detonators in the loading cup 9 of the loading tray 2.2 can be poured into the roller 4.3 one by one through the flip feeding mechanism 3.

[0035] After the detonators are poured into the polishing roller 4.3, the servo motor drives the polishing roller 4.3 to rotate around the rotation center line parallel to the mounting surface of the frame 1, so that the detonators in the polishing roller 4.3 are mixed with the wood chips, and the polishing of the detonators is completed.

At this time, the sawdust outlet at the bottom of the screening drum 5.1 faces the sawdust trough 6, and the detonator outlet of the screening drum 5.1 faces the lower left. Then the screening drum 5.1 screens the detonator and sawdust inside, wherein the sawdust falls into the conical discharge bin at the bottom of the screening drum 5.1, and finally falls into the sawdust trough 6 through the sawdust outlet. The detonator is discharged from the detonator outlet of the screening drum 5.1.

[0040] In this embodiment, a guide groove 5.2 is installed in the feed port of the screening drum 5.1. When the polishing drum 4.3 pours the detonator into the screening drum 5.1, the guide groove 5.2 plays a guiding role.

A plurality of circular holes are provided in the material unloading tray 8.2, each of which passes through the material unloading tray 8.2 vertically, and the circular holes are distributed in an annular manner at equal intervals around the center of the material unloading tray 8.2. The circular holes of the material unloading tray 8.2 are used to place empty material cups. When placed, the material cups are in a vertical state with the cup mouth facing upward, and the bottom of the material cups are stuck in the circular holes of the material unloading tray 8.2.

[0043] In this embodiment, the receiving bin mechanism 7 is arranged on the mounting surface of the frame 1, and the receiving bin mechanism 7 is located at the upper right of the discharging mechanism 8 and the lower left of the drum screening mechanism 5, that is, the receiving bin mechanism 7 is located at the upper right of the discharging mechanism 8 and between the drum screening mechanism 5.

The receiving bin 7.1 vibrates, causing the detonators to fall into the material cups carried on the material tray 8.2 in the discharging mechanism 8. By rotating the material tray 8.2, the polished detonators can be sequentially loaded into the material cups on the material tray 8.2 one by one.

[0045] In the discharging mechanism 8 of this embodiment, the unloading tray 8.2 is equipped with a weighing device 8.3, which is a lifting weighing device. The weighing device 8.3 is installed below the unloading tray 8.2, and the weighing device 8.3 is located below the rotation path of any round hole in the unloading tray 8.2. When a round hole of the unloading tray 8.2 rotates to the top of the weighing device 8.3, the lifting weighing device passes through the round hole to lift the material cup on the round hole, thereby completing the overall weighing of the material cup and the detonator therein. Through the cooperation of the discharging mechanism 8, the weighing device 8.3 and the receiving bin mechanism 7, the detonator after rolling and polishing can be automatically divided into boxes and loaded.
