[0021] The embodiments of the utility model will be described below with reference to the drawings.

[0022] Embodiment 1: A gunpowder compression device for firecracker production, as shown in the figure, comprising a chassis 1; Figures 1-4

[0023] The fixed frame 2 is connected to one side of the top of the chassis 1 by bolts; ​

[0024] The lower hopper 3 is obliquely arranged by being bolted to the upper portion of the fixed frame 2.

[0025] The lower feeding mechanism arranged on the fixed frame 2 is used for intermittent automatic feeding.

[0026] The compaction mechanism arranged on the base frame 1 is used for powder compaction treatment.

[0027] The upper portion of the fixed frame 2 is provided with two notches, and the discharge port of the lower hopper 3 is flush with one of the notches of the fixed frame 2.

[0028] The lower feeding mechanism comprises a rotating disc 4 connected to the fixed frame 2 through a bearing, a plurality of notches are arranged on the rotating disc 4, a plurality of receiving boxes 5 are respectively welded in the plurality of notches of the rotating disc 4, a motor 6 is fixedly connected to the lower portion of the fixed frame 2, a chain wheel one 7 is fixedly connected to one side of the rotating disc 4, a chain wheel two 8 is fixedly connected to the output shaft of the motor 6, a chain 9 is wound between the chain wheel one 7 and the chain wheel two 8, the motor 6 drives the chain wheel one 7 to rotate through the chain wheel two 8 and the chain 9, and then drives the rotating disc 4 and the receiving boxes 5 to rotate.

[0029] The plurality of receiving boxes 5 are obliquely arranged, and the oblique arrangement can make the paper tube more conveniently enter and leave the receiving boxes 5 by gravity.

[0030] The lower feeding mechanism comprises a support frame 10 bolted to the top of the base frame 1, two double-stage hydraulic push rods 11 fixedly connected to the support frame 10, the two double-stage hydraulic push rods 11 are symmetrically arranged, a lower pressing frame 12 fixedly connected to the first telescopic rod of the two double-stage hydraulic push rods 11, and a compaction frame 13 fixedly connected to the second telescopic rod of the two double-stage hydraulic push rods 11, the lower pressing frame 12 and the compaction frame 13 are located above the receiving boxes 5, the double-stage hydraulic push rods 11 drive the lower pressing frame 12 and the compaction frame 13 to move downward, and then limit the paper tube and compact the powder in the paper tube.

[0031] At the beginning, the staff fills the lower hopper 3 with the paper tube filled with gunpowder, and the opening of the paper tube faces upward, and the clay bottom faces downward. After the paper tube is placed, the staff starts the motor 6, the output shaft of the motor 6 rotates to drive the sprocket wheel two 8 to rotate, the sprocket wheel two 8 rotates to drive the sprocket wheel one 7 to rotate through the chain 9, the sprocket wheel one 7 rotates to drive the rotating disc 4 to rotate, and the rotating disc 4 rotates to drive a plurality of receiving boxes 5 to rotate. One of the receiving boxes 5 moves to be flush with the discharge port of the lower hopper 3, and then the staff stops the motor 6. Under the action of gravity, the paper tube in the lower hopper 3 slides into the receiving box 5. Through the above operation, the paper tube can be intermittently and automatically replenished, and the work efficiency is improved. Then the staff controls the motor 6 to continue to rotate, and the rotating disc 4 continues to rotate to block the discharge port of the lower hopper 3, so that the paper tube in the lower hopper 3 is prevented from falling during rotation. The next receiving box 5 moves to be flush with the discharge port of the lower hopper 3, and the paper tube is filled again. The receiving box 5 filled with the paper tube continues to rotate and moves to the lower side of the lower pressing frame 12. At this time, the staff stops the motor 6, and controls the two-stage hydraulic push rod 11 to extend downward. The one-stage and two-stage telescopic rods of the two-stage hydraulic push rod 11 move downward to drive the lower pressing frame 12 and the compacting frame 13 to move downward. The lower pressing frame 12 moves downward to contact one of the receiving boxes 5 below which is provided with the paper tube, and limits the paper tube in the receiving box 5. Then the one-stage telescopic rod of the two-stage hydraulic push rod 11 stops, and the two-stage telescopic rod continues to extend downward. The two-stage telescopic rod of the two-stage hydraulic push rod 11 continues to move downward to drive the compacting frame 13 to pass through the lower pressing frame 12 and insert into the paper tube. The compacting frame 13 continues to move downward to compress and compact the gunpowder in the paper tube. Through the above operation, the gunpowder in a plurality of paper tubes can be compressed at the same time, and the work efficiency is further improved. After the gunpowder is compressed, the staff controls the two-stage hydraulic push rod 11 to retract upward. The two-stage telescopic rod of the two-stage hydraulic push rod 11 moves upward to drive the compacting frame 13 to move upward and reset. After the two-stage telescopic rod of the two-stage hydraulic push rod 11 is retracted, the one-stage telescopic rod continues to retract upward, so that the lower pressing frame 12 and the compacting frame 13 are reset to the initial state. The paper tube whose gunpowder is compressed moves downward and out of the receiving box 5 under the action of gravity after the receiving box 5 rotates to be flush with the other notch of the fixed frame 2. The staff uses a container to receive the compressed paper tube at the discharge notch of the fixed frame 2. Then the staff repeats the above operation until all the paper tubes in the lower hopper 3 are completely processed. After the work is completed, the staff turns off the motor 6.

[0032] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
