Technical Field

[0001] This application belongs to the field of fireworks production technology and relates to a sealing powder filling device for fireworks inner tubes. Background Technology

[0002] In the fireworks production process, the filling of the inner tube sealing powder is one of the key steps to ensure the fireworks' ignition effect and safety. Traditional inner tube sealing powder filling mainly relies on manual operation or simple mechanical devices, which has the following technical drawbacks: Manual filling is labor-intensive, slow, and difficult to meet the needs of large-scale production; furthermore, manual operation is susceptible to fatigue, leading to quality fluctuations. The sealing powder is usually a fine-particle flammable substance, and manual filling easily generates dust, which not only harms worker health but also poses a dust explosion hazard.

[0030] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0032] This embodiment discloses a sealing powder filling device for a fireworks inner tube, such as... Figures 1-5 As shown, it includes:

[0033] The support frame 1 and the support base plate 2 supported by the support frame 1 are provided. The support base plate 2 is provided with a discharge plate 3 inside, and the discharge plate 3 is provided with a discharge port 31.

[0034] Hopper 5 is used to limit the diffusion of sealing powder;

[0035] A first scraper mechanism 6 and a second scraper mechanism 7 are provided on the hopper 5. The first scraper mechanism 6 includes a plurality of scrapers 63 evenly arranged along a first direction, and the extension direction of each scraper 63 is perpendicular to the first direction. The second scraper mechanism 7 includes at least one brush 72 arranged along a second direction, which is orthogonal to the first direction, and the brush surface of the brush 72 is parallel to the first direction. The first scraper mechanism 6 and the second scraper mechanism 7 are used to control the discharge.

[0036] The drive mechanism includes a first cylinder 21 mounted on the support base plate 2, which is used to drive the hopper 5 to move.

[0037] It should be noted that the discharge port 31 is set to correspond to the feed port of the inner tube of the fireworks. The first direction refers to the length direction of the hopper 5. Several scrapers 63 are arranged at equal intervals in the first direction about the discharge port 31, so that when the scrapers 63 move, they can carry the sealing powder directly into the discharge port 31. The second direction refers to the width direction of the hopper 5. When the drive mechanism moves the hopper 5, it can drive the brush 72 to move, so that the remaining sealing powder after being scraped by the scrapers 63 can be carried and discharged into the inner tube of the fireworks through the discharge port 31.

[0038] Among them, the discharge plate 3 plays a positioning role, that is, the discharge port 31 corresponds one-to-one with the positions of several openings in the inner tube of the fireworks.

[0039] Sealing powder is conveyed from hopper 5 to discharge plate 3. Some of the sealing powder is directly discharged into the inner tube of the fireworks through discharge port 31. Then, the scraper 63 of the first scraper mechanism 6 is driven to move, which drives the sealing powder on the discharge plate 3 into the discharge port 31. Finally, the drive mechanism drives hopper 5 to move, which causes the brush 72 of the second scraper mechanism 7 to move, which drives the remaining sealing powder to be discharged into the inner tube of the fireworks through discharge port 31. On the one hand, this reduces the impact of dust diffusion, and on the other hand, it improves the filling efficiency of sealing powder.

[0040] like Figures 1-4 As shown, there are multiple discharge ports 31, which are arranged in a honeycomb pattern corresponding to the inner tube of the fireworks;

[0041] The honeycomb arrangement consists of several hexagonal unit arrays, with each discharge port 31 located at the center of the unit, and the spacing between adjacent discharge ports 31 is equal.

[0042] like Figure 5 As shown, the first scraper mechanism 6 also includes a second cylinder 61. The second cylinder 61 is mounted on the outside of the hopper 5 through a cylinder fixing plate. The output end of the second cylinder 61 is provided with a fixing rod 62, and the scraper 63 is fixed to the fixing rod 62 through a connecting rod.

[0043] It should be noted that the second cylinder 61 drives the fixed rod 62 to move, and the movement of the fixed rod 62 drives the scraper 63 to move.

[0044] like Figures 1-4 As shown, the drive mechanism also includes a track 22, which is arranged parallel to the axis of the first cylinder 21. A slider 23 is provided on the outside of the track 22, and the slider 23 is connected to the actuator of the first cylinder 21 through a hopper support plate 24.

[0045] It should be noted that the track 22 and the slider 23 are used to limit the movement path of the hopper 5 driven by the drive mechanism.

[0046] like Figure 3 and Figure 5 As shown, the hopper 5 is provided with a hopper bottom plate 4 on the outside, and the hopper bottom plate 4 is installed on the top of the hopper support plate 24.

[0047] like Figure 5 As shown, the second scraper mechanism 7 also includes a third cylinder 71, which is mounted on the top of the hopper bottom plate 4 via a cylinder fixing plate. The output end of the third cylinder 71 is provided with a brush mounting plate, and the brush 72 is fixed to the brush mounting plate.

[0048] It should be noted that the third cylinder 71 drives the brush mounting plate to move, and the brush mounting plate drives the brush 72 to move.

[0049] like Figure 2 As shown, it also includes a fourth cylinder 8, which is mounted on the support frame 1. The push rod of the fourth cylinder 8 is provided with a clamp 81, which is used to clamp the inner tube of the firework.

[0050] like Figures 1-5 As shown, the brush 72 is located outside the hopper 5, and the included angle between the brush 72 and the hopper 5 is α, where 0° < α < 90°.

[0051] It should be noted that the brush 72 is tilted so that the side wall of the discharge port 31 can be cleaned by the deformation of the brush bristles when it passes through the discharge port 31.

[0052] like Figures 1-5 As shown, scraper 63 is a metal plate, and the working surface of scraper 63 is a smooth outer wall.

[0053] It should be noted that the smooth outer wall of the scraper 63 can reduce the adhesion of sealing powder.

[0054] like Figures 1-5 As shown, the hopper 5 has a feed inlet, and the outlet end of the feed inlet is a funnel-shaped flared structure with an isosceles trapezoidal cross section.

[0055] It should be noted that the flared structure helps to limit the diffusion range of the sealing powder after it passes through the feed inlet of the hopper 5, so that the diffusion range of the sealing powder is limited to the discharge outlet 31 of the discharge plate 3.

[0056] Working principle: Sealing powder is conveyed from hopper 5 to discharge plate 3. Part of the sealing powder is directly discharged into the inner tube of the fireworks through discharge port 31. Then, the scraper 63 of the first scraper mechanism 6 is driven to move, which drives the sealing powder on the discharge plate 3 into the discharge port 31. Finally, the drive mechanism drives hopper 5 to move, which causes the brush 72 of the second scraper mechanism 7 to move, which drives the remaining sealing powder to be discharged into the inner tube of the fireworks through discharge port 31. On the one hand, this reduces the impact of dust diffusion, and on the other hand, it improves the filling efficiency of sealing powder.

[0057] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
