DETAILED DESCRIPTION

[0029] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1 , 2 The flare cutting machine shown includes a body 1, a cutter 2 and a turntable 3 driven by a power mechanism. The cutter 2 is fixed to the upper surface of the body 1. The edge of the turntable 3 is provided with a slot 4 that matches the cutter 2. The edge of the turntable 3 is provided with a limiting structure for positioning the flare. The slot 4 is arranged between the limiting structures. The cutter corresponds to the felt washer at the junction between the flare primer and the astral body. The flare is limited by the limiting structure on the edge of the turntable. The power mechanism drives the turntable to rotate, which can drive the flare to rotate with the turntable. When the flare rotates to the cutter position, the primer of the flare can be cut off. Using this technical solution to replace manual cutting greatly reduces the labor intensity of operators, improves the work safety factor, and also improves the mechanization degree and work efficiency of flare decomposition. It is more conducive to environmental protection than burning in the wild.

[0031] As a preferred structure, Figure 1 , 2 As shown in Figures 5 and 6, the limiting structure includes a first limiting groove 5 and a second limiting groove 6 for matching the outer circle of the flare. The first limiting groove 5 and the second limiting groove 6 are respectively arranged on the edges of the turntable 3 above and below the slot 4. The inner diameter of the first limiting groove is smaller than the outer diameter of the bottom of the flare. The flare can be placed on the first limiting groove and the second limiting groove on the edge of the turntable. As the turntable rotates, the flare is driven to rotate relative to the cutter, and the cutter is used to cut the flare.

[0032] In a specific embodiment of the present invention, Figure 1 , 2 As shown in Figures 5 and 6, the first limiting groove 5 is a U-shaped groove with its opening facing outward, and the second limiting groove 6 is a through hole matching the outer circle of the flare. After the primer of the flare is cut off, it can slide out along the U-shaped first limiting groove for easy collection.

[0033] Further optimize the above technical solution, such as Figure 1 , 2 As shown in 7-10, the upper surface of the fuselage 1 is also provided with a material discharging mechanism for discharging the cut flare primer out of the turntable 3, and the material discharging mechanism includes a material baffle plate 7 and a material discharging plate 8, and the material baffle plate 7 is arranged above the cutter 2; the material baffle plate 7 and the material discharging plate 8 both include a straight edge and an arc portion, the straight edge of the material baffle plate 7 is arranged on the outside of the turntable 3, and the arc portion of the material baffle plate 7 coincides with the outer edge of the turntable 3; the straight edge of the material discharging plate 8 is tangent to the edge of the turntable 3, the end of the arc portion of the material discharging plate 8 is inclined toward the inner side of the turntable 3, and the outer edge of the arc portion of the material discharging plate 8 is tangent to the bottom of the first limiting groove 5; the end of the arc portion of the material discharging plate 8 is staggered with the starting end of the arc portion of the material discharging plate 7, and the straight edge of the material discharging plate 8 is perpendicular to the straight edge of the material baffle plate 7. After the flare is placed in the first and second limit slots, the motor of the power mechanism is started, and the turntable starts to rotate clockwise, driving the flare to rotate toward the cutter to meet the inertia effect, and the primer of the flare can be quickly cut off. The lower starlight body will fall under the fuselage, and the separated primer will continue to rotate along the turntable and the baffle plate. At the discharge port, as the turntable rotates, the material shifting plate will shift the primer to the outside of the turntable. Then continue to place the next flare in the first and second limit slots, and repeat the above steps.

[0034] In a preferred embodiment of the present invention, Figure 2 , 4 As shown, the two ends of the cutter 2 are provided with a fixing plate 9, and the two ends of the cutter 2 are fixed on the cutter seat 10 through a positioning pin 15. The two ends of the fixing plate 9 are arranged on the cutter seat 10 through a connecting piece, and the fixing plate 9 is arranged above the cutter 2; the cutter seat 10 is arranged on the upper surface of the fuselage 1; the middle part of the cutter seat 10 is provided with a trapezoidal groove 11, the cutter 2 is arranged above the middle groove 11 of the cutter seat 10, and the two ends of the cutter 2 are arranged on the upper surfaces of the two ends of the cutter seat 10. The trapezoidal groove in the middle of the cutter seat is convenient for accommodating the cutter, and it is also convenient for the signal flare to turn here to interact with the cutter to complete the cutting of the primer. In addition, the end of the arc portion of the material blocking plate 7 is arranged at the middle position of the groove of the cutter seat 10. At this time, the first limit groove and the center line of the turntable are perpendicular to the length direction of the cutter, which can achieve a thorough cutting of the signal flare. The cut primer continues to rotate along the gap between the material blocking plate and the material diverting plate until it slides to the outside of the turntable.

[0035] In a specific embodiment of the present invention, Figure 7-10As shown, the baffle plate 7 and the material stripping plate 8 are both steel plates with one end fixed to the upper surface of the machine body 1 and the other end free; the straight edge of the baffle plate 7 is fixed to the side of the cutter seat 10, and the arc portion of the baffle plate 7 is arranged around the turntable 3; the end of the straight edge of the material stripping plate 8 is connected to the machine body 1, and the arc portion of the material stripping plate 8 is arranged on the upper surface of the turntable 3. Figure 1 , 2 As shown, the straight edge of the stripper plate 7 is fixed on a support column 12 , and the support column 12 is fixed on the upper surface of the fuselage 1 .

[0036] In order to facilitate the collection of cut flares, such as Figure 3 As shown, a primer guide groove 13 and a starlight guide groove 14 are provided below the cutter 2, and both the primer guide groove 13 and the starlight guide groove 14 are arranged inside the fuselage 1, and the outlet ends are inclined downward toward the outside of the fuselage 1; the arc portion of the baffle plate 7 has a length of one-fourth of the circumference of the turntable 3, and the starlight guide groove 14 is arranged below the end of the arc portion of the baffle plate 7; the primer guide groove 13 is arranged below the intersection of the straight edge of the baffle plate 7 and the arc portion of the material-diverting plate 8. When the flare is cut, the starlight that falls down will slide along the starlight guide groove to the outside of the fuselage for easy collection; the primer above the turntable will rotate along the material-diverting plate to the outside of the turntable, and slide along the primer guide groove to the outside of the fuselage for easy collection.

[0037] In order to facilitate classification and collection, a primer collection box and a starlight collection box are respectively provided below the outlet ends of the primer guide groove 13 and the starlight guide groove 14.

[0038] In a specific embodiment of the present invention, Figure 5 As shown, the turntable 3 includes a chassis 31 and a cover plate 32. The chassis 31 is coaxially fixed with the output shaft of the power mechanism, and a plurality of second limiting grooves 6 are arranged around the chassis 31; an annular boss is arranged on the upper surface of the chassis 31, and the cover plate 32 is an annular plate matched with the outer circle of the boss, and a plurality of first limiting grooves 5 corresponding to the second limiting grooves 6 are arranged around the cover plate 32; an annular step is arranged on the edge of the chassis 31, and a slot 4 for accommodating the cutter 2 is formed between the step surface and the lower bottom surface of the cover plate 32, and the second limiting groove 6 is arranged on the step surface. There are 8 first limiting grooves and second limiting grooves, which correspond to each other from top to bottom and are evenly distributed around the edges of the turntable. This structure is convenient for processing and manufacturing, and is also convenient for loading and unloading and maintenance. Among them, the power mechanism includes a motor and a gear set, and the starting motor drives the chassis to rotate through the gear set, thereby driving the signal flare to rotate toward the cutter.

[0039] The specific operation process of the present invention is as follows:

[0040] Start the motor, the turntable rotates, and the signal flare is manually placed from the feeding port into the limit structure of the turntable. The signal flare sets the turntable to rotate quickly and contact the cutter. The starlight body is separated from the primer, and the decomposition of the signal flare is completed. Then the starlight body and the primer slide out from the primer guide groove and the starlight body guide groove respectively for collection. Then, the next signal flare moves to the cutter position to complete the decomposition, and the cycle is repeated to achieve batch decomposition of the signal flare.

[0041] In summary, the present invention has the advantages of simple and compact structure, high degree of automation, and high safety factor for flare cutting. It can improve the efficiency of flare decomposition, reduce a large amount of labor input, protect the surrounding environment, and effectively recover the copper metal of the primer to reduce resource waste.

[0042] In the above description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed above.
