Description

Technical Field

[0001] The utility model relates to an automatic explosive weighing and packing system, belonging to the technical field of ammunition production. Background Art

[0002] In the ammunition production industry, explosives weighing and packaging processes are typically performed manually. First, the packaging bag is placed in the ammunition box, then the box is weighed on an electronic scale, and the explosives are added in multiple steps until the specified weight is reached. However, manual weighing and packaging of explosives involves extensive human contact, making it very easy for the explosives to explode due to manual mishandling or accidental factors, resulting in major safety accidents. Furthermore, the floating explosives produced during the dumping process can be easily inhaled, potentially affecting health, and can easily be scattered, posing a safety hazard. This is particularly true when quantitatively weighing large quantities of explosives (over 10 kg).

[0003] Therefore, it is urgent to propose a new type of automatic explosive weighing and packing system to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is described below using specific embodiments illustrated in the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

The fixed connection refers to a non-detachable connection, including but not limited to conventional fixed connection methods such as hem connection, rivet connection, bonding connection, and welding connection. The detachable connection refers to but not limited to conventional detachable connection methods such as threaded connection, snap connection, pin connection, and hinge connection. When the specific connection method is not clearly specified, it is assumed that at least one connection method can always be found among the existing connection methods to achieve the function. Those skilled in the art can choose according to their needs. For example, a welded connection is selected for a fixed connection, and a hinge connection is selected for a detachable connection.

[0020] Specific implementation method 1: Combination Figure 1-Figure 3 The present embodiment is described. The present embodiment is an automatic weighing and packing system for explosives, comprising a feeding mechanism 1, a weighing and lifting mechanism 2, a weighing and clamping mechanism 3, an electronic scale 4, a conveyor 5 and a vibration device 6. An electronic scale 4 is provided below the feeding mechanism 1. The electronic scale 4 is provided with a weighing and lifting mechanism 2 symmetrically arranged on the left and right. The weighing and clamping mechanism 3 is installed on the weighing and lifting mechanism 2. The conveyor 5 spans the electronic scale 4 front to back and is provided between the weighing and clamping mechanisms 3 on the left and right sides. A vibration device 6 is also provided above the electronic scale 4. That is, the number of the weighing and lifting mechanism 2 and the weighing and clamping mechanism 3 is set to two.

[0021] The conveyor 5 is used to transport wooden boxes that need to be loaded with explosives. There are packaging bags in the wooden boxes. The conveyor 5 transports them between the two weighing and clamping mechanisms 3. The weighing and clamping mechanisms 3 clamp and position the wooden boxes containing the packaging bags. The weighing and lifting mechanism 2 drives the weighing and clamping mechanism 3 to achieve lifting and lowering, and separates it from the conveyor 5. Then the unloading mechanism 1 is started to inject explosive raw materials into the packaging bags. At the same time, the electronic scale 4 weighs synchronously until the specified weight is reached. The unloading mechanism 1 is closed, the weighing and lifting mechanism 2 drops to the initial position, and the wooden box drops onto the conveyor. Then the vibration device 6 is started, using the principle of high-frequency vibration to reduce or eliminate the accumulation angle of the material in the packaging bag, which is convenient for subsequent bag sealing processing.

[0022] The weighing clamping mechanism 3 can be clamped by a cylinder to hold the wooden box on both sides to position the wooden box;

[0023] The weighing and lifting mechanism 2 can lift the wooden box clamped by the weighing and clamping mechanism 3 to a certain height through the cylinder, separate it from the conveyor 5, and send the empty bags in the wooden box into the discharge pipe to facilitate unloading and boxing.

[0024] The unloading mechanism 1 includes a unloading pipe 11, a pipe clamp valve 12 and a dust removal hood 13. The unloading pipe 11 is provided with a pipe clamp valve 12, and a dust removal hood 13 is provided at the outlet of the unloading pipe 11. The unloading pipe 11 is a pipeline for material flow and packing. The pipe clamp valve 12 is used for switching control of material loading into the wooden box. At the same time, the valve positioner provided on the pipe clamp valve 12 can steplessly control the cylinder stroke, thereby controlling the material flow rate during the packing process. The dust removal hood 13 is connected to a negative pressure dust collection device for extracting material dust during the packing process.

[0025] The electronic scale 4 is used to monitor the charge amount at any time during the packing process, and the system controls the pipe clamp valve 12 for coarse feeding and fine feeding according to the charge amount.

[0026] The vibration device 6 includes a vibration lifting mechanism 61, a vibration clamping mechanism 62 and a vibration mechanism 63. The vibration lifting mechanism 61 vertically penetrates the conveyor 5 and is arranged on the front and rear sides of the electronic scale 4. The vibration clamping mechanism 62 is installed on the vibration lifting mechanism 61 on the front and rear sides, and the vibration mechanism 63 is arranged on any one or both sides of the vibration lifting mechanism 61.

[0027] The vibrating clamping mechanism 62 can be clamped by the cylinder to hold the wooden box on both sides to position the wooden box, and then the vibrating clamping mechanism 62 can use its own cylinder to lift the wooden box to a certain height, separate from the conveyor 5, and send the empty material packaging bags in the wooden box into the discharge pipe 11 to facilitate unloading and boxing. When the wooden box is loaded, the vibrating mechanism 63 vibrates and loosens the material in the wooden box through a vibration source such as a vibrating cylinder, reduces or eliminates the stacking angle of the material in the packaging bag, and facilitates subsequent manual bag sealing processing.

[0028] The weighing and clamping mechanism 3 includes a telescopic cylinder 31 and a bracket 32. The telescopic cylinder 31 is fixedly installed on the weighing lifting mechanism 2. The output end of the telescopic cylinder 31 is provided with the bracket 32. When the weighing and clamping mechanism 3 is working, the telescopic cylinder 31 drives the bracket 32 ​​to extend and retract to realize the clamping action.

[0029] This embodiment also includes a method for automatic weighing and packing of explosives, which is implemented based on the automatic weighing and packing system for explosives, and includes the following steps:

[0030] Step 1: First, the wooden box containing the packaging bags is transported to the designated packaging position by conveyor 5;

[0031] Step 2: The weighing clamping mechanism 3 clamps the wooden box from both sides;

[0032] Step 3: The weighing and lifting mechanism 3 lifts the wooden box and removes it from the conveyor 5. At the same time, the packaging bag in the wooden box rises, and the discharge pipe 11 enters the packaging bag;

[0033] In step 4, the explosives are fed by gravity through the clamp valve 12 and the discharge pipe 11 into the packaging bag of the wooden box for rough feeding to ensure the packing speed; the weight of the material in the packaging bag can be monitored at any time by the electronic scale 4 below the weighing and lifting mechanism 2. When the material surface rises and is very close to the nozzle of the discharge pipe 11, the weighing and lifting mechanism 2 is lowered to a certain height to prevent the material surface from burying the discharge pipe nozzle, while ensuring that the nozzle of the discharge pipe 11 is close to the material surface to minimize material dust; until the material is loaded to the predetermined weight, the opening of the clamp valve 12 is gradually reduced to perform fine feeding to ensure the packing accuracy. When the specified weight is reached, the clamp valve 12 is completely closed and the packaging is completed;

[0034] Step 5: The weighing and lifting mechanism 2 descends to its initial position, and the wooden box descends onto the conveyor 5;

[0035] Step 6: If the material is not evenly distributed in the box and the material surface has a high taper angle, the vibrating lifting mechanism 61 lifts the box and removes it from the conveyor 5. Simultaneously, the vibrating clamping mechanism 62 clamps the box on both sides. The vibrating mechanism 63 vibrates the loaded box, utilizing the principle of high-frequency vibration to reduce or eliminate the accumulation angle of the material in the bag, facilitating subsequent bag sealing.

[0036] Step 7: After the vibration is completed, the vibration lifting mechanism 61 descends, and the wooden box is lowered onto the conveyor to complete the automatic boxing work.

[0037] It should be noted that in the above embodiments, as long as the technical solutions are not contradictory, they can be permuted and combined. Those skilled in the art can exhaust all possibilities based on the mathematical knowledge of permutations and combinations. Therefore, the present invention will no longer describe the technical solutions after permutations and combinations one by one, but it should be understood that the technical solutions after permutations and combinations have been disclosed by the present invention.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
