Description

Technical Field

[0001] This application belongs to the technical field of fireworks production equipment, and relates to a fireworks inner tube loading device. Background Technology

[0002] The inner tube of a firework is the core component of a combination firework product. It needs to be filled with specific types and weights of effect powder to achieve the desired ignition effect. The accuracy, uniformity, and consistency of the powder filling in the inner tube directly determine the quality, safety, and performance of the final firework product.

[0003] Currently, the industry generally uses fixed hoppers and valves for loading fireworks inner tubes. By controlling the opening and closing time or frequency of the valves, the propellant flows into the inner tube by gravity. While this method reduces manual contact to some extent, the amount of propellant loaded is greatly affected by the size, density, humidity, flowability, and material level in the hopper. Quantitative accuracy is difficult to guarantee, and the valves are prone to propellant adhesion and blockage, leading to interruptions in dispensing or inaccurate dosages. Frequent manual cleaning and maintenance are required, affecting continuous production. Summary of the Invention

[0021] 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.

[0022] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0023] This embodiment discloses a fireworks inner tube loading device, such as... Figures 1-8 As shown, it includes: The frame 1 is provided with a feeding mechanism 2 and a positioning mechanism 3 in sequence. The positioning mechanism 3 clamps the inner tube of the fireworks with a clamp 38 for positioning. The feeding mechanism 2 fills the inner tube of the fireworks with powder through a metering mechanism 8. The feeding mechanism 2 includes a material box 5 and a second cylinder 42 for pushing the material box 5 to move in a first direction. The material box 5 is provided with a plurality of scrapers 56 and a third cylinder 52 for controlling the scrapers 56 to move in a second direction. The positioning mechanism 3 includes a clamp 56 and a first adjustment component 34 and a second adjustment component 36 for controlling the position of the clamp 56 in a first direction and a second direction. The positioning mechanism 3 is pushed to move in the vertical direction by the lifting mechanism 9. The feeding mechanism 2 also includes a vibrating plate 4 and a dispensing base plate 7 housed at the bottom of the vibrating plate 4. The vibrating plate 4 and the dispensing base plate 7 are respectively provided with through mounting grooves, which are used to install the metering mechanism 8. The dispensing mechanism 8 includes a guide plate 83 fixed to the bottom of the dispensing base plate 7. The guide plate 83 is provided with two limiting rods 831. The two limiting rods 81 together form the lateral limiting of the movable baffle 82. The top of the movable baffle 82 is provided with a dispensing plate 81. The guide plate 83 is provided with a limiting screw 832. The movable baffle 82 is provided with a movable groove 822 corresponding to the limiting screw 832. When the movable baffle 82 is driven by the baffle cylinder 821, the movable groove 822 cooperates with the limiting screw 832 to constrain and limit the movement stroke of the movable baffle 82.

[0024] It should be noted that the first direction refers to the working direction of the second cylinder 42, and the second direction refers to the working direction of the conveyor belt 32, and the first direction and the second direction are perpendicular.

[0025] It should be noted that the bottom of the vibrating plate 4 has a receiving space that matches the dispensing base plate 7. The dispensing base plate 7 is embedded in this receiving space to reduce the thickness of the two after assembly. The metering plate 81, the movable baffle 82, and the guide plate 83 are coaxially provided with filling holes for filling powder. When the three are placed inside the mounting groove composed of the main support plate 2 and the dispensing base plate 22, the upper surface of the metering plate 81 is coplanar with the upper surface of the vibrating plate 4, and the two limiting rods 831 provided on the guide plate 83 abut against the... The two sides of the metering plate 81 and the movable baffle 82 serve to limit and fix the position. The length of the movable baffle 82 is shorter than the length of the guide plate 83. Therefore, the movable baffle 82 can move under the action of the baffle cylinder 821, causing the filling hole of the movable baffle 82 to be misaligned with the filling hole of the metering plate 81. This closes the filling hole of the metering plate 81, allowing the powder to fill the filling hole of the metering plate 81. Then the movable baffle 82 moves away, and the powder can fall down, which can help complete the subsequent metering of the powder.

[0026] The position of the clamp 38 is gradually adjusted by the first adjusting component 34 and the second adjusting component 36. At the same time, the baffle 381 can restrict the position of the inner tube of the firework in the first direction under the action of the first adjusting component 34. At this time, there is still a gap between the clamp 38 and the inner tube of the firework. Therefore, the clamp 38 can be moved directly by the first cylinder 37 so that the clamp 38 moves closer to the inner tube of the firework. The second adjusting component 36 can move the clamp 38 closer to the inner tube of the firework in the second direction to complete the clamping and positioning of the inner tube of the firework by the clamp 38. Then, the lifting mechanism 9 moves the inner tube of the firework positioned by the clamp 38 closer to the guide plate 83 of the metering mechanism 8. At this time, the feeding mechanism 2 can scrape the powder into the filling hole of the metering plate 81 by the scraper 56. The vibration of the vibrator 44 can promote the filling. Finally, the movable baffle 82 moves away so that the powder falls into the inner tube of the firework through the filling hole of the guide plate 83, completing the metering filling.

[0027] like Figure 7 and Figure 8As shown, the positioning mechanism 3 also includes a fixing plate 31 mounted on the bracket 91 of the lifting mechanism 9. The fixing plate 31 is driven to move in the vertical direction by the fifth cylinder 92. A conveyor belt 32 driven by a motor 321 is mounted on the fixing plate 31.

[0028] like Figure 7 and Figure 8 As shown, a fixed frame 33 is provided on the fixed plate 31, a first adjustment component 34 is installed on the fixed frame 33, a second adjustment component 36 is installed on the first adjustment component 34 via a movable frame 35, a clamp 38 is driven by a first cylinder 37, the first cylinder 37 is installed on the second adjustment component 36, and a baffle 381 is installed on the movable frame 35.

[0029] It should be noted that the first adjusting component 34 and the second adjusting component 36 can be a combination of a double-ended screw and a nut. By limiting the nut to prevent it from rotating, the nut can be moved in the direction of the screw when the double-ended screw rotates. This allows the nut to drive other structures connected to the nut to move. For example, the two double-ended screws of the first adjusting component 34 can be connected by a synchronous pulley and rotate together, causing the two sets of nuts to move relative to or away from each other. This, in turn, causes the second adjusting component 36 on the nut to move relative to or away from each other, thereby adjusting the position of the clamp 38 in the first direction. The second adjusting component 36 can also adjust the position of the clamp 38.

[0030] like Figure 2 and Figure 5 As shown, the vibrating plate 4 is provided with a barrier 41, which is used to contain the powder.

[0031] like Figure 1 and Figure 2 As shown, the vibrating plate 4 is equipped with a vibrator 44, and the vibrating plate 4 is fixed to the frame 1 by a shock absorber 43.

[0032] like Figures 2-4 As shown, the top of the material box 5 is provided with a hopper 51, and a third cylinder 52 is installed on the outside of the material box 5. The third cylinder 52 is connected to a slider 53 through a connector. The slider 53 inside the material box 5 is provided with a sliding rod 54. A screw 55 is fixed at the tail end of the slider 53. An isolation sleeve 551 is provided on the outside of the screw 55. A scraper 56 is provided on the outside of the isolation sleeve 551.

[0033] It should be noted that the third cylinder 52 can drive the slider 53 to slide outside the slide rod 54, and at the same time drive the screw 55, the isolation sleeve 551 and the scraper 56 to move. The isolation sleeve 551 can promote the falling of the powder and prevent the scraper 56 from squeezing the powder together when it moves relative to the isolation sleeve 551.

[0034] like Figure 3 and Figure 4 As shown, there is an active gap between the scraper 56 and the isolation sleeve 551, and guide plates 561 are provided on both sides of the material box 5, and a shielding plate 562 is provided on the top of the guide plate 561. The guide plate 561 has a curved and continuous arc-shaped guide surface on the side facing the scraper 56. When the third cylinder 52 drives the scraper 56 to move, the scraper 56 is limited by the guide plate 561 and shakes in the first direction.

[0035] It should be noted that the third cylinder 52 drives the scraper 56 to move. One side of the scraper 56 is squeezed by the guide plate 561 and moves to the other side, so that the arc-shaped guide surface of the guide plate 561 has different curvatures. This allows the scraper 56 to reciprocate and shake at the same time when it moves, thereby scraping the powder into the metering mechanism 8.

[0036] like Figure 4 As shown, the material box 5 has a limiting plate 57 inside, and first fixing rods 571 are provided on both sides of the limiting plate 57. The material box 5 also has a second fixing rod 572 inside. It should be noted that the limiting plate 57, the first fixing rods 571 and the second fixing rods 572 can divert the powder and improve the structural stability of the material box 5.

[0037] like Figures 1-3 As shown, the bottom of the material box 5 is provided with a rubber strip 58, the outside of the rubber strip 58 is provided with a protective plate 581, the outside of the material box 5 is equipped with a fourth cylinder 59, and the output end of the fourth cylinder 59 is provided with a second brush 591.

[0038] like Figures 1-8 As shown, it also includes a stopper mechanism 6, which is disposed on the feeding mechanism 2 and is driven to move in a first direction by the second cylinder 42. The stopper mechanism 6 is used to clear the filling hole of the metering mechanism 8.

[0039] It should be noted that the filling mechanism 6 is driven by a cylinder or motor and is designed to fit the structure of the inner tube of the fireworks. It consists of one or more push rods fixed to a fixed plate or other fixed structure. The push rods are driven to squeeze the filling hole of the metering mechanism 8, thereby clearing the filling hole and allowing the powder to fall into the inner tube of the fireworks.

[0040] Working principle: The position of the clamp 38 is gradually adjusted by the first adjustment component 34 and the second adjustment component 36. Then, the lifting mechanism 9 drives the inner tube of the firework, which is positioned by the clamp 38, to gradually approach the guide plate 83 of the quantitative mechanism 8. At this time, the feeding mechanism 2 can scrape the powder into the filling hole of the quantitative plate 81 through the scraper 56. The vibration of the vibrator 44 can promote filling. Finally, the movable baffle 82 moves away, so that the powder falls into the inner tube of the firework through the filling hole of the guide plate 83, completing the quantitative filling.

[0041] 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.
