Embodiment 1

[0035] like figure 1 and figure 2 The shown automatic weighing and discharging device for energetic raw materials includes a feeding mechanism 2, a weighing cup 3 located below the outlet of the feeding mechanism 2, and the weighing cup 3 is fixedly connected to the drive shaft 4, The weighing cup 3 can rotate with the driving shaft 4, and the end of the driving shaft 4 away from the weighing cup 3 is fixedly connected to the shift fork 8; it also includes a rotating device 10, which is used to drive the shifting block 9 to rotate ; The shift fork 8 can rotate with the shift block 9 ; It also includes a load cell 11 , and the load cell 11 is used to monitor the weight change of the weighing cup 3 .

Embodiment 2

[0037] like Figure 1 to Figure 5 In the shown automatic weighing and discharging device for energetic raw materials, on the basis of Example 1, the drive shaft 4 passes through the bearing seat 5, and a bearing 13 matching the drive shaft 4 is arranged in the bearing seat 5 , the bearing housing 5 is fixed on the load cell 11 . It also includes a mounting plate 1 on which the feeding mechanism 2 , the load cell 11 and the rotating device 10 are all fixed. A through groove 801 is provided on the side surface of the shift fork 8 facing the direction of the shift block 9 , and the shift block 9 is located in the through groove 801 . The width of the through slot 801 is 3-4 mm larger than the width of the shifting block 9 . It also includes a positioning bead 6, and the shift fork 8 is provided with a positioning groove 802 matching the positioning bead 6, and the positioning bead 6 is located on the movement track of the matching positioning groove 802. The positioning bead 6...

Embodiment 3

[0039] A method for automatic weighing and pouring of powder materials, such as Figure 1 to Figure 5 shown, including the following steps:

[0040] (a) The mouth of the weighing cup 3 is upward, and the feeding mechanism 2 feeds the material into the weighing cup 3, and the weight increment of the weighing cup 3 monitored by the load cell 11 is the material weight;

[0041] (b) When the weight of the material in the weighing cup 3 reaches the set value, the feeding mechanism 2 stops discharging, and the rotating device 10 starts to move, driving the shifting block 9 to rotate 180°, and the shifting block 9 drives the shifting fork 8 to rotate 180° At this time, the positioning groove 802 on the shift fork 8 rotates to face the positioning bead 6, and the positioning bead 6 enters the positioning groove 802 under the action of the elastic member; at the same time, the shift fork 8 drives the drive shaft 4 to rotate, so that the weighing cup 3 also rotate 180° in the same dire...

Abstract

The invention discloses an automatic weighing and pouring device and method for an energetic raw material. The device comprises a feeding mechanism and a weighing material cup positioned below a discharging hole of the feeding mechanism; the weighing material cup is fixedly connected with a driving shaft; the weighing material cup can rotate along with the driving shaft; one end, far away from theweighing material cup, of the driving shaft is fixedly connected with a shifting fork; the device further comprises a rotating device; the rotating device is used for driving a shifting block to rotate; the shifting fork can rotate along with the shifting block; the device further comprises a weighing sensor; and the weighing sensor is used for monitoring the weight change of the weighing material cup. According to the automatic weighing and pouring device and method for the energetic raw material, the problems of low weighing and pouring efficiency, low automation degree, high potential safety hazard and complex structure of the initiating explosive device and civil explosion industry in the prior art are solved, so that the purposes of improving the automation degree, realizing the man-machine separation and ensuring the personnel safety are achieved.

Description

technical field [0001] The invention relates to the field of pyrotechnics, in particular to an automatic weighing and discharging device and method for energetic raw materials. Background technique [0002] In the existing technology, the pyrotechnics and civil explosives industries still mainly use manual or simple equipment production methods for weighing and measuring operations. This production mode is not highly automated, and a large number of people directly contact with the agent, which has great potential safety hazards. ; and the weighing production efficiency is low and the weight consistency is difficult to guarantee, resulting in high cost of mass production, unable to form efficient production capacity, and seriously affecting the development progress of the pyrotechnics and civil explosive industries. In the few existing automatic weighing equipment, the weighing device and the feeding device are independent mechanisms, and the automatic drug feeding mechanism...
