Description

Technical Field

[0001] The utility model belongs to the technical field of fireworks charging machinery, in particular to a fireworks charging machine. Background Art

[0002] Since the inner diameter of a single paper tube of a firework is relatively large and the amount of gunpowder loaded must be relatively accurate, the existing firework loading method has always adopted the traditional manual loading method, which is slow, inefficient, requires many operators and is unsafe. There is an urgent need for an automated firework loading mechanical production line to replace manual operation.

[0003] To solve the above problems, the Chinese utility model patent with application number CN202021215999.9 provides a quantitative charging device for firecracker paper tube cakes, including a mixing bin for mixing materials evenly by a mixing device, and a quantitative template assembly arranged below the mixing bin for controlling the falling of materials in the mixing bin; the utility model adopts a quantitative template assembly composed of upper and lower templates and a movable template with quantitative holes, and utilizes the movable template that moves back and forth to cooperate with the upper and lower templates that are staggered from each other to quantitatively pour the mixed gunpowder in the mixing bin into each inner tube of the empty paper tube cake, which can ensure the accurate gunpowder charging amount of the firecracker paper tube cake, and has the advantages of fast speed, high degree of automation, stable operation and safety.

[0004] However, when the device is actually used, it can only load gunpowder into the firecracker paper tube cakes on a conveyor belt, and the working efficiency is not high enough. Utility Model Content

[0005] In view of this, the purpose of the present invention is to overcome the deficiencies in the prior art and provide a firework charging machine. The present application provides the following technical solutions:

[0006] It includes a frame, on which is provided a silo and a material distributor located at the material silo discharge port, a quantitative template assembly is provided below the material distributor, a slide rail assembly is provided on the frame, a slidable sliding platform is provided on the slide rail assembly, and a plurality of the quantitative template assemblies are mounted on the sliding platform; the sliding platform slides back and forth to make the quantitative template assemblies move to the bottom of the material distributor in sequence.

[0007] The quantitative template assembly includes an upper template installed on the sliding platform, a lower template fixed under the upper template, and a movable template arranged between the upper template and the lower template and driven by a driving component to slide back and forth; the upper template and the lower template are respectively provided with a first quantitative hole and a second quantitative hole that are offset, and the movable template is provided with quantitative holes that can correspond to the first quantitative hole on the upper template and the second quantitative hole on the lower template respectively.

[0008] The driving component includes a pushing cylinder installed at the bottom of the sliding platform and a guide rod installed at the bottom of the upper template, and the guide rod is equipped with a slider; the movable template is fixedly connected to the slider, and a limiting block is provided on the side of the guide rod close to the pushing cylinder, and a compression spring is provided on the side away from the pushing cylinder.

[0009] The driving component is arranged in this way, while the pushing cylinder is not directly connected to the movable template, the movable template is connected to the upper template and the lower template through the slider guide rod to form a combination. When it is necessary to charge firework paper tubes of different models and sizes, the entire combination can be removed from the sliding platform and replaced with other upper templates, lower templates and movable templates with different numbers and sizes of quantitative holes.

[0010] The material equalizer includes a rotating motor, a rotating shaft connected to the main shaft of the rotating motor, a plurality of arc-shaped scraping strips fixed at the lower end of the rotating shaft, and rake nails arranged under the scraping strips, and the rake nails under each of the scraping strips are staggered; the rotating motor is installed on the frame, and the bottom of the rake nails is located on the upper surface of the quantitative template assembly.

[0011] The upper surface of the quantitative template assembly is flush with the upper surface of the sliding platform; the material distributor also includes a material barrel, the top of which is fixed to the frame, and the bottom of the material barrel is covered with a silicone sleeve, and the bottom of the silicone sleeve is in contact with the upper surface of the quantitative template assembly.

[0012] Through the above arrangement, after the material bin is unloaded, the medicine powder is contained in the material barrel. Since the silicone sleeve at the bottom of the material barrel is flush with the upper surface of the quantitative template assembly and the sliding platform, the medicine powder will not leak out from the bottom of the silicone sleeve when the sliding platform slides, making the surface of the sliding platform tidier, reducing the waste of medicine powder, and improving the utilization rate of medicine powder.

[0013] The slide rail assembly includes a slide shaft and a driving cylinder installed on the frame; a linear bearing is provided on the slide shaft; both ends of the sliding platform are fixedly connected to the linear bearing; and the telescopic end of the driving cylinder is fixedly connected to the sliding platform.

[0014] A plurality of linear bearings are arranged on the sliding shafts, and sealing tubes are sealed between the linear bearings, and oil is sealed in the sealing tubes; an oil seal is arranged at the outer end of the linear bearing that is not connected to the sealing tube.

[0015] Through the above arrangement, when the linear bearing slides along the slide rail, the oil plays a lubricating role, reduces the friction between the linear bearing and the slide rail, and prevents the powder from falling into the gap between the linear bearing and the slide rail. The powder that falls onto the slide rail is not easily ignited due to the friction between the linear bearing and the slide rail, thereby reducing the occurrence of accidents.

[0016] The frame is also provided with a material pushing assembly, and the material pushing assembly is arranged on the side of the material equalizer along the sliding direction of the sliding platform.

[0017] The pushing assembly comprises a pushing cylinder mounted on the frame, a pushing plate is arranged below the pushing cylinder, the pushing plate is fixedly connected to the telescopic end of the pushing cylinder, and a plurality of pushing rods are fixed at the bottom of the pushing plate.

[0018] By setting up a pushing component, after the quantitative module component drops the powder into the firework paper tube, the pushing component pushes the powder in the paper tube so that the powder falls completely into the bottom of the firework paper tube.

[0019] A conveyor belt is arranged below the pushing assembly, and a clamping assembly is arranged on the conveyor belt and directly below the pushing assembly; the clamping assembly includes a first positioning fork and a second positioning fork arranged on the conveyor belt and driven by a synchronous driving mechanism to perform relative clamping and reverse opening movements.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0021] A plurality of quantitative module components are provided and are arranged on a sliding platform. After the material bin is unloaded, when the material distributor is evenly charging one quantitative module component, other quantitative module components can perform other work, such as charging work, loading the powder in the quantitative module component into the firework paper tube. The plurality of quantitative module components are charged in turn, and the interval time between each charging is shorter, which greatly improves the labor efficiency.
