Description

Technical Field

[0001] This application belongs to the technical field of explosive processing and relates to a housing flipping mechanism. Background Art

[0002] In the field of explosive production, as the core charge unit, the charge column needs to be accurately loaded into the protective housing by an upper housing machine to meet safety and performance requirements. After being formed, the charge columns usually enter the conveyor line in a horizontal or disordered posture and need to be flipped, arranged directionally, and then discharged one by one so as to be accurately aligned with the housing and complete the loading. In the traditional process, this link mainly relies on manual flipping and arranging of the charge columns, which has problems such as low efficiency, high labor intensity, and high safety risks. Direct contact between personnel and high-risk charge columns is likely to cause accidents, and it is difficult for manual operations to match the rhythm of the automated production line.

[0003] Existing mechanical flipping mechanisms (such as fixed-inclination chutes and single-degree-of-freedom flipping arms) are mostly designed for specific charge column sizes and weights and are difficult to be compatible with products of different specifications. Factors such as the aspect ratio and center-of-gravity offset of the charge columns are likely to cause the posture to get out of control during the flipping process, resulting in jams or stacking, and frequent shutdown intervention is required, making it difficult to achieve continuous production.

[0004] Therefore, how to provide a housing flipping mechanism to achieve high-precision and high-reliability directional discharge of charge columns has become a technical problem to be solved urgently. Summary of the Invention

[0036] The technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0037] This embodiment discloses a housing flipping mechanism for driving the propellant charge 100 to flip by a specified angle and discharge one by one, as Figures 1-8 shown, including:

[0038] Bracket 1, with first linear motion modules 3 symmetrically arranged on both sides of bracket 1;

[0039] Second linear motion module 4, which is connected in a straddling manner to two first linear motion modules 3 through a mounting plate to achieve linkage;

[0040] Rotary motion module 5, which is arranged on the mounting bracket 44 of the second linear motion module 4;

[0041] Flipping housing 6, which is arranged on the rotating block 53 of the rotary motion module 5. The flipping housing 6 includes a housing 61 with an inlet for the propellant charge 100. An outlet 22 is provided on the first side of the housing 61, the second side is closed. A blocking module 8 and an upper limit module 7 are sequentially provided on the top of the housing 61, and a belt-driven lead screw module 9 is provided at the bottom of the housing 61;

[0042] When the propellant charge 100 is flipped, the blocking module 8, the upper limit module 7, and the belt-driven screw module 9 respectively abut against the propellant charge 100 from the end where the outlet 22 of the housing 61 is located, the top end, and the end where the inlet is located, so as to form a limit for a plurality of propellant charges 100.

[0043] Among them, when the belt-driven screw module 9 operates, it can drive the propellant charge 100 to roll from the end where the inlet of the housing 61 is located to the end where the outlet 22 is located.

[0044] It should be noted that the first linear motion module 3, the second linear motion module 4, the rotary motion module 5, the blocking module 8, the upper limit module 7, and the belt-driven screw module 9 can be driven by a cylinder or by a motor, as long as they can realize the movement of the specified structure on the preset route. The housing 61 is provided with grooves corresponding to the blocking module 8, the upper limit module 7, and the belt-driven screw module 9.

[0045] As Figure 7 shown, the upper limit module 7 includes a fourth cylinder 71 provided on the housing 61. A fixed frame 72 is fixedly provided outside the piston rod of the fourth cylinder 71.

[0049] As Figure 7 and Figure 8 shown, the belt-driven screw module 9 includes a second motor 91 and a screw 94 provided at the bottom of the housing 61. A synchronous pulley 92 is fixedly connected to the outside of the motor shaft of the second motor 91. A matching synchronous pulley 92 is provided at the first end of the screw 94. The two synchronous pulleys 92 are linked by a synchronous belt 93. A moving block 95 is provided at the second end of the screw 94.

[0050] As Figure 8 shown, a sixth cylinder 96 is installed outside the moving block 95, and a third baffle 97 is provided outside the sixth cylinder 96.

[0051] It should be noted that the belt-driven lead screw module 9 is driven by the second motor 91 to drive the synchronous pulley 92 and the synchronous belt 93, so as to drive the lead screw 94 to rotate. When the movement block 95 arranged outside the lead screw 94 is restricted in rotation, it will perform a reciprocating motion along with the rotation direction of the lead screw 94, so as to drive the sixth cylinder 96 to adjust its position, and then drive the third baffle 97 that moves on a fixed path by means of the sixth cylinder 96 to realize the limitation and adjustment of the position of the propellant column 100.

[0052] As Figure 7 shown, a protective cover 64 for covering the belt-driven lead screw module 9 is provided at the bottom of the housing 61.

[0053] As Figure 5 and Figure 6 shown, the rotary motion module 5 includes a first motor 51 arranged on the mounting frame 44, and the first motor 51 drives the rotating block 53 to perform a flipping action through the hollow rotary platform 52.

[0054] It should be noted that the hollow rotary platform 52 is a prior art, which is driven by the first motor 51 and is used to achieve precise angle adjustment and can drive the flipping housing 6 to flip.

[0055] As Figure 6 shown, the second linear motion module 4 includes a third cylinder 41 and a second guide rail 42 arranged on the mounting plate, and the third cylinder 41 is used to drive the second slider 43 to slide on the second guide rail 42.

[0056] It should be noted that when the third cylinder 41 drives the second slider 43 to slide on the second guide rail 42, it can drive the rotary motion module 5 arranged on the mounting frame 44 to adjust its position.

[0057] As Figure 5 shown, the first linear motion module 3 includes a second cylinder 31 and a first guide rail 32 arranged on the bracket 1, and the second cylinder 31 is used to drive the first slider 33 to slide on the first guide rail 32.

[0058] It should be noted that when the second cylinder 31 drives the first slider 33 to slide on the first guide rail 32, it can drive the second linear motion module 4 arranged on the mounting plate to adjust its position.

[0059] As Figures 1-5 shown, it further includes a feeding component 2. The feeding component 2 is arranged outside the bracket 1 and includes: an inclined material guiding groove 21 and a first cylinder 24 fixed on the bracket 1. A vibrator 22 is installed at the bottom of the material guiding groove 21, a cover plate 23 is arranged at the top of the material guiding groove 21, and a first baffle 25 is arranged outside the first cylinder 24. The first baffle 25 is used to block the discharge of the propellant column 100.

[0060] It should be noted that the feeding assembly 2 is used to place the horizontally placed propellant charge 100 into the interior of the housing 61. The first cylinder 24 can drive the first baffle 25 to move on a preset path.

[0061] Working principle: The propellant charge 100 is placed into the interior of the housing 61 through the feeding assembly 2. After the propellant charge 100 is limited by the blocking module 8, the upper limit module 7 and the belt-driven lead screw module 9, the rotary motion module 5 is used to control the flipping of the flipping housing 6 and the propellant charge 100, so as to discharge the propellant charge 100 one by one from the outlet 62 of the housing 61 by means of gravity. Among them, the first linear motion module 3 and the second linear motion module 4 can drive the flipping housing 6 to approach or move away from the feeding assembly 2, realizing the directional and quantitative discharge of the propellant charge 100 with high precision and high reliability, and providing a stable feeding basis for automatic loading.
