Description

Technical Field

[0001] This application relates to the field of fireworks production equipment technology, and in particular to an inner cylinder loading component and fireworks production equipment. Background Technology

[0002] The inner tube of a firework, also known as a firework effects tube, contains bright beads, gunpowder, fillers, and igniters. Both the bright beads and gunpowder are flammable and explosive. When fireworks are set off, the inner tube can produce various effects, such as vibrant colors and a variety of sounds.

[0003] When producing combination fireworks, the inner tube needs to be inserted into the outer tube. Chinese patent CN202522334571.5 discloses a feeding assembly for the inner tube of fireworks. This feeding assembly utilizes the rotation of a transfer frame to transfer and load the inner tube, enabling automated filling of the inner tube and eliminating the need for workers to approach the material hopper to perform the feeding operation. However, the feeding assembly provided in this patent document also has some drawbacks: First, in the feeding assembly provided in this patent document, the transfer frame needs to be inserted through an opening in the isolation wall. The rotation of the transfer frame causes the material frame on the rotating frame to reciprocate between the two sides of the isolation wall. In order to cross the isolation wall and reach the positions on both sides, the rotation radius of the material frame needs to be large enough. Therefore, the rotation of the transfer frame requires a large space, necessitating a large opening in the isolation wall to accommodate the rotational movement of the transfer frame. Furthermore, the transfer frame will not detach from the opening in the isolation wall during movement, making it impossible to install a safety door in the opening of the isolation wall. The isolation effect of the isolation wall is insufficient, and the safety is not high enough. Second, the partition wall and transfer frame need to fit very closely, making equipment installation inconvenient. Third, the rotation radius of the material frame is relatively large, and the rotational inertia of the transfer frame is significant, which can easily lead to inaccurate positioning.

Detailed Implementation

[0032] The following are specific embodiments of this application, described in conjunction with the accompanying drawings, to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope of protection of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0034] The inner cylinder loading assembly provided in this application is used in automated fireworks production equipment, which can automatically feed the inner cylinder. During production, workers do not need to approach the hopper to feed the inner cylinder, which ensures high safety.

[0035] refer to Figures 1-6 The inner cylinder loading assembly includes a hopper 10, an inner cylinder cake feeding mechanism 20, a rotating mechanism 30, and a pushing mechanism 40.

[0036] The hopper 10 is used to load the inner cylinder; the hopper 10 is arranged on the second side of the partition wall 60.

[0037] The inner cylinder cake feeding mechanism 20 includes a movable chamber 21 and a first drive unit 22; the movable chamber 21 is capable of loading the inner cylinder cake; the first drive unit 22 is used to drive the movable chamber 21 to move through the isolation wall 60 to a first position or a second position; wherein, the first position is located on the first side of the isolation wall 60, and the second position is located on the second side of the isolation wall 60.

[0038] The rotating mechanism 30 is arranged on the second side of the partition wall 60. The rotating mechanism 30 includes a rotating frame 31 and a second drive unit 32. A plurality of material frames 311 are arranged on the rotating frame 31. The second drive unit 32 is used to drive the rotating frame 31 to rotate so that the material frames 311 on the rotating frame are aligned with the hopper 10 or with the movable bin 21 located in the second position.

[0039] When the material frame 311 is aligned with the moving bin 21, the moving bin 21 can load the inner cylinder cake into the material frame 311; when the material frame 311 is aligned with the hopper 10, the inner cylinder in the material frame 311 is pushed into the hopper 10 by the pushing mechanism 40.

[0040] When the first drive unit 22 drives the moving bin 21 to move through the isolation wall 60 to the first position, since the first position is located on the first side of the isolation wall 60, the equipment or operators can load the inner cylinder cake into the moving bin 21 from the first side of the isolation wall 60. Therefore, when loading the inner cylinder cake, the loading operator does not need to enter the second side of the isolation wall 60. In this design, the isolation wall separates the loading operator from the hopper 10, rotating mechanism 30, and other mechanisms, achieving human-machine separation and increasing the safety of the loading operator.

[0041] When the first drive unit 22 drives the movable bin 21 to move through the partition wall 60 to the second position, the movable bin 21 enters the second side of the partition wall 60. When the movable bin 21 is in the second position, the second drive unit 32 can drive the rotating frame 31 to rotate so that the material frame 311 on the rotating frame is aligned with the movable bin 21; when the material frame 311 is aligned with the movable bin 21, the movable bin 21 loads the inner cylinder cake into the material frame 311.

[0042] When the second drive unit 32 drives the rotating frame 31 to rotate so that the material frame 311 on the rotating frame is aligned with the hopper 10, the pushing mechanism 40 can push the inner cylinder in the material frame 311 into the hopper 10.

[0043] In some embodiments, the hopper 10 is configured with a hexagonal structure, which matches the shape of the inner cylinder cake and can just accommodate the inner cylinder of one inner cylinder cake. Therefore, when the material frame 311 is aligned with the hopper 10, the pushing mechanism 40 can push the inner cylinder in the material frame 311 into the hopper 10.

[0044] In some embodiments, the mobile bin 21 is provided with a slide structure 211 and an inner cylinder cake ejection mechanism. The slide structure 211 can load inner cylinder cakes; when the material frame 311 is aligned with the mobile bin 21, the inner cylinder cake ejection mechanism can sequentially push the inner cylinder cakes in the slide structure 211 forward to load them into the material frame 311. When the first drive unit 22 drives the mobile bin 21 to move through the partition wall 60 to the first position, the equipment or operator can load inner cylinder cakes onto the slide structure 211 of the mobile bin 21 from the first side of the partition wall 60. When the first drive unit 22 drives the mobile bin 21 to move through the partition wall 60 to the second position, the second drive unit 32 can drive the rotating frame 31 to rotate so that the material frames 311 on the rotating frame 31 are aligned with the mobile bin 21 one by one. Each time the mobile bin 21 is aligned with a material frame 311, the inner cylinder cake ejection mechanism ejects an inner cylinder cake and loads it into the material frame 311. In one specific embodiment, the first drive unit 22 can be configured as a cylinder, and the second drive unit 32 can be configured as a cylinder, motor, etc.

[0045] In some embodiments, reference Figure 3 The inner cylinder cake ejection mechanism includes a timing belt device 212 and a second pusher 213; the timing belt device 212 extends in the same direction as the slide structure 211. The timing belt device 212 can drive the second pusher 213 to move to push the inner cylinder cake in the slide structure 211.

[0046] Specifically, the synchronous belt device 212 is used to drive the second pusher 213 to move along the slide structure 211 to push out the inner cylinder cakes one by one in the slide structure 211. The synchronous belt device 212 is a commonly used device in the prior art, which includes a synchronous toothed belt, toothed pulleys, a motor, etc. The synchronous toothed belt is tensioned by multiple toothed pulleys and forms a meshing transmission. Since there is no relative sliding between the synchronous toothed belt and the toothed pulleys, synchronous transmission is ensured and the transmission ratio is constant. The second pusher 213 is connected to the synchronous toothed belt of the synchronous belt device 212. As the motor drives the toothed pulleys to rotate, the synchronous toothed belt can drive the second pusher 213 to move back and forth.

[0047] In some embodiments, the material frame 311 has a first side A and a second side B facing each other; when the inner cylinder cake passes through the material frame 311 from the first side A to the second side B, the material frame 311 can block the tie of the inner cylinder cake and allow the inner cylinder to pass through. When the material frame 311 is aligned with the moving bin 21, the moving bin 21 loads the inner cylinder cake from the first side A of the material frame 311 into the material frame 311; when the material frame 311 is aligned with the hopper 10, the pushing mechanism 40 pushes the inner cylinder of the inner cylinder cake in the material frame 311 into the hopper 10 from the first side A to the second side B.

[0048] Specifically, when the material frame 311 is aligned with the moving bin 21, the moving bin 21 is located on the first side A of the material frame 311, and the inner cylinder cake pushed out by the moving bin 21 can be loaded into the material frame 311 from the first side A. When the material frame 311 is aligned with the hopper 10, the pushing mechanism 40 is located on the first side A of the material frame 311, and the hopper 10 is located on the second side B of the material frame 311. The pushing mechanism 40 can push the inner cylinder in the material frame 311 into the hopper 10 from the first side A of the material frame 311. During this process, the inner cylinder cake enters the material frame 311 from the first side A and is pushed out from the second side B of the material frame 311. The material frame 311 blocks the tie of the inner cylinder cake and allows the inner cylinder to pass through. Finally, the inner cylinder of the inner cylinder cake enters the hopper 10, and the tie of the inner cylinder cake is peeled off by the material frame 311 without manual removal of the tie.

[0049] In some embodiments, the pushing mechanism 40 includes a first pusher 41 and a third drive unit 42; when the material frame 311 is aligned with the hopper 10, the third drive unit 42 drives the first pusher 41 to push the inner cylinder in the material frame 311 into the hopper 10. In one specific embodiment, the third drive unit may be configured as a cylinder.

[0050] In some embodiments, reference Figure 5 The inner cylinder loading assembly also includes a door panel mechanism 50; the door panel mechanism 50 is used to close or open the opening 61 on the partition wall 60 through which the mobile compartment 21 passes.

[0051] In some embodiments, the door panel mechanism 50 includes: a door panel 51 and a fourth drive unit 52; the fourth drive unit 52 is used to drive the door panel 51 to close or open the opening 61 on the partition wall 60.

[0052] Specifically, when the first drive unit 22 drives the mobile compartment 21 to pass through the isolation wall 60, the door opening mechanism 50 can be controlled to open the opening. After each time the mobile compartment 21 passes through the isolation wall 60, the door opening mechanism 50 can be used to close the opening 61 after the mobile compartment 21 has passed through, thereby strengthening the isolation and improving safety.

[0053] In some embodiments, a plurality of material frames 311 are arranged circumferentially around the rotating frame 31; as the second drive unit 32 drives the rotating frame 31 to rotate, each material frame 311 of the rotating frame 31 is sequentially aligned with the moving bin 21 and the hopper 10. (Reference) Figure 4 Two material frames 311 are provided on the rotating frame 31.

[0054] In some embodiments, the angular distribution of the material frames 311 allows the moving bin 21 and the hopper 10 to be simultaneously aligned with two material frames 311 at different angular positions during the rotation of the rotating frame 31. This configuration allows the loading of the inner cylinder cake into the material frame and the pushing of the inner cylinder into the hopper 10 to occur simultaneously, effectively improving the equipment's working efficiency.

[0055] In some embodiments, two material frames 311 are arranged on the rotating frame 31, respectively on both sides of the rotation axis of the rotating frame 31; when one material frame 311 is aligned with the moving bin 21, the other material frame 311 is aligned with the hopper 10. Therefore, when one material frame 311 is loading the inner cylinder, the other material frame 311 is discharging the inner cylinder, and the loading and discharging of the inner cylinder are carried out alternately, thereby reducing the idling of the equipment and improving efficiency.

[0056] In this application, each drive unit can be configured as various types as needed, such as motors, cylinders, etc.

[0057] In this embodiment, the first drive unit drives the moving bin to move through the partition wall to a first or second position on either side of the partition wall. During operation, the moving bin loads the inner cylinder cake at the first position on the first side, then moves through the partition wall to the second position, where it loads the inner cylinder cake into the material frame. Finally, as the rotating frame rotates, when the material frame aligns with the hopper, the inner cylinder in the material frame is pushed into the hopper by the pushing mechanism. The technical advantage of the inner cylinder loading assembly provided in this application is that by using the moving bin to move through the partition wall to the first or second position on either side of the partition wall, the required opening area of ​​the partition wall is small, and a door panel mechanism can be arranged to close the opening, achieving better isolation and higher safety. Furthermore, the equipment installation is more convenient. In addition, the rotating frame has a small rotation radius and low inertia, and the inertia has a smaller impact on positioning accuracy.

The hopper is used to load the inner cylinder and is located on the second side of the partition wall. The inner cylinder cake feeding mechanism includes a moving bin and a first drive unit. The moving bin can load the inner cylinder cake. The first drive unit drives the moving bin to move through the partition wall to a first position or a second position. The first position is located on the first side of the partition wall, and the second position is located on the second side of the partition wall. The rotating mechanism is located on the second side of the partition wall and includes a rotating frame and a second drive unit. Several material frames are arranged on the rotating frame. The second drive unit drives the rotating frame to rotate so that the material frames on the rotating frame are aligned with the hopper or the moving bin located at the second position. When the material frames are aligned with the moving bin, the moving bin can load the inner cylinder cake into the material frames.
