Description

Technical Field

[0001] This application relates to the field of fireworks production equipment technology, and in particular to a feeding device, feeding method and production equipment for combined fireworks inner tubes. Background Technology

[0002] Firework inner tube filling equipment is a key specialized piece of equipment in fireworks production. It is used to safely, accurately, and efficiently fill pre-made fireworks inner tubes (also known as "effect tubes" or "sub-tubes") into the fireworks mass (also known as "outer tubes," "launch tubes," "base," or "mother tube"). Typically, the inner tube cake is the basic unit of fireworks production. The inner tube cake is composed of multiple inner tubes assembled together by tie-down straps, forming a hexagonal shape.

[0003] Currently, fireworks inner tube filling equipment can automatically remove the tie straps from the inner tube cake via a feeding mechanism to release the inner tube. In some technical solutions, the inner tube is released onto a conveyor platform and diverted for filling. However, after the tie straps are removed, the inner tube, no longer restrained, is prone to tipping over during the feeding process. Summary of the Invention

The feeding chute connects to each diversion channel to guide the inner cylinder into each channel.

[0007] The first pushing mechanism has a first pushing member for pushing the inner cylinder and a first driving assembly; the first driving assembly is used to drive the first pushing member to move; the first pushing member is used to push the inner cylinder in the feed chute from the rear to the front so that the inner cylinder in the feed chute remains in an aggregated state when it slides forward.

[0009] When the second pusher and the guard are in their initial positions, the guard and the second pusher are placed one after the other in the feeding chute. The feeding chute in the space between them forms the loading space of the inner cylinder, which can just accommodate the inner cylinder of one inner cylinder cake. When the second pusher pushes the inner cylinder in the loading space forward along the feeding chute, the guard moves forward synchronously.

[0010] When the holding member catches up with the first pushing member, the first pushing member and the holding member exit the feeding chute so that the inner cylinder in the loading space merges and gathers with the inner cylinder in front; and after the first pushing member exits the feeding chute, it retracts to the position of the second pushing member and takes over from the second pushing member to continue pushing the inner cylinder.

[0011] Optionally, the first layer platform is provided with a first loading port; when the second pusher and the guard are in the initial position, the first loading port is located at the bottom of the loading space;

[0016] The fourth drive component can drive the frame component to move to a first position or a second position on the second platform; when the frame component moves to the first position, the variable material trough transforms into a rectangular state and aligns with the first feeding port position, and the first lifting mechanism can lift the inner cylinder in the variable material trough from the bottom into the loading space; when the frame component moves to the second position, the variable material trough transforms into a hexagonal state to accommodate the inner cylinder.

[0018] The feeding device also includes a third-layer platform, a moving material frame mechanism, and a second lifting mechanism;

[0019] The third-layer platform is located below the second-layer platform and can be used to vertically place the inner cylinder;

[0020] The moving material frame mechanism includes a moving material frame and a fifth drive component; the moving material frame is located on the third-layer platform and forms a material trough on the third-layer platform; the material trough is hexagonal and can just accommodate the inner cylinder of an inner cylinder cake;

[0021] The fifth drive component can drive the movable material frame to move to the third position or the fourth position on the third platform; when the movable material frame moves to the third position, the material trough is aligned with the second feeding port, and the second lifting mechanism can lift the inner cylinder in the material trough into the variable material trough; when the movable material frame moves to the fourth position, the inner cylinder is inserted; the movable material frame inserts the inner cylinder at the fourth position.

[0022] Optionally, the first-layer platform is divided into a first area, a second area, and a third area from front to back; wherein the diversion channel is arranged in the third area, and the feeding chute is arranged in the first area and the second area;

[0023] The first area is provided with a first baffle and a second baffle, which are parallel to each other and form the rear section of the feed chute between them; the first feed port is arranged in the rear section of the feed chute.

[0024] A third and a fourth baffle are arranged on the second area, and the third and fourth baffles form the front section of the feed chute;

[0025] The first pusher, the second pusher, and the guard are all located in the rear section of the feed chute and are matched with the width of the rear section of the feed chute.

[0026] Optionally, the first platform includes a front platform support and a rear platform support, the first region and the second region are arranged on the front platform support, and the third region is arranged on the rear platform support; the front platform support is equipped with a vibration component, which is used to apply vibration to the front platform support to move the inner cylinder on the first region and the second region forward.

[0027] Optionally, the second pusher has a transverse protrusion at the bottom front side; when the second pusher pushes the inner cylinder, the transverse protrusion contacts the lower part of the inner cylinder, and there is a gap between the front side of the second pusher and the upper part of the inner cylinder; the first pusher can be inserted into the gap to take over from the second pusher and continue pushing the inner cylinder.

[0028] Optionally, the frame assembly has six enclosure members; when the variable trough is transformed into a hexagonal state, its six sides correspond one-to-one with the six enclosure members.

[0030] The second drive assembly includes two drive units, one for driving the second pusher and the support to move back and forth, and the other for driving the support to move up and down.

[0031] On the other hand, this application also provides a method for feeding a firework inner tube, the method being applied to the aforementioned feeding device; comprising the following steps:

[0032] The first driving component drives the first pusher to push the inner cylinder in the feed chute from the rear to the front, so that the inner cylinder in the feed chute remains in an aggregated state when it slides forward.

[0033] The second drive assembly drives the second pusher and the guard to move to the initial position. The guard and the second pusher are placed one in front of the other in the feed chute. The feed chute section between them forms a loading space for loading the inner cylinder. Furthermore, when the second pusher pushes the inner cylinder in the loading space forward along the feed chute under the drive of the second drive assembly, the guard moves forward synchronously.

[0034] When the holding member catches up with the first pushing member, the first pushing member and the holding member exit the feeding chute so that the inner cylinder in the loading space merges and gathers with the inner cylinder in front; and after the first pushing member exits the feeding chute, it retracts to the position of the second pushing member and takes over from the second pushing member to continue pushing the inner cylinder.

[0035] On the other hand, this application also provides a production equipment for combined fireworks, including the aforementioned feeding device.

[0036] This application utilizes a first pushing mechanism and a second pushing mechanism in cooperation to feed the inner cylinder. When the second pushing member pushes the inner cylinder in the loading space forward along the feeding slide, the supporting member moves forward synchronously, maintaining constraint on the inner cylinder during the movement. When the supporting member catches up with the first pushing member, the first pushing member and the supporting member exit the feeding slide so that the inner cylinder in the loading space merges with the inner cylinder in front of it; furthermore, after exiting the feeding slide, the first pushing member returns to the position of the second pushing member and takes over pushing the inner cylinder. During the feeding process, both the existing inner cylinder on the first platform and the newly placed inner cylinder in the loading space are sufficiently constrained, thereby preventing the inner cylinder from tipping over and ensuring the continuity of the feeding process.

[0037] In some technical solutions, the feeding device also includes a second-level platform, a variable material frame mechanism, and a first lifting mechanism. The variable material trough transforms into a hexagonal or rectangular state. In its hexagonal state, the variable material trough matches the shape of the inner cylinder cake, allowing the inner cylinder of one inner cylinder cake to be completely inserted into the variable material trough. In both its rectangular and hexagonal states, the variable material trough can precisely accommodate the inner cylinder of one inner cylinder cake. The frame assembly can move to a first or second position on the second-level platform. When the frame assembly moves to the first position, the variable material trough transforms into a rectangular state and aligns with the first feeding port. The first lifting mechanism can then lift the inner cylinder from the bottom of the variable material trough into the loading space. When the frame assembly moves to the second position, the variable material trough transforms into a hexagonal state to accommodate the inner cylinder. In this design, the inner cylinder of the hexagonal inner cylinder cake is loaded into the variable material trough and eventually transformed into a rectangular state before being output into the loading space. The pushing mechanism pushes the inner cylinder forward along the first-level platform. After the inner cylinder is transformed into a rectangular distribution, it is less likely to tip over during the pushing and merging process. Attached Figure Description

Detailed Implementation

[0047] 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.

[0048] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0049] The inner cylinder is released onto the conveyor platform and diverted for filling. However, after the tie straps on the inner cylinder are removed, the inner cylinder, no longer restrained, is prone to tipping over during the feeding process. Therefore, this application provides a feeding device for fireworks inner cylinders that can prevent the inner cylinder from tipping over during feeding, ensuring the continuity of the feeding process.

[0050] refer to Figures 1-5The feeding device includes a first platform 10, a first pushing mechanism 20, and a second pushing mechanism 30. The first platform 10 can hold the inner cylinder vertically. Multiple transversely arranged diversion channels 131 are arranged near the front of the first platform 10, which are used to divert the inner cylinder forward. Side rails are arranged on both sides behind the diversion channels 131, and a feeding chute is formed between the side rails to allow the inner cylinder to slide forward. The feeding chute connects to each diversion channel 131 to guide the inner cylinder into each diversion channel 131. The first pushing mechanism 20 has a first pushing member 21 for pushing the inner cylinder and a first driving assembly 22. The first driving assembly 22 drives the first pushing member 21 to move. The first pushing member 21 pushes the inner cylinder forward from the rear of the inner cylinder into the feeding chute, so that the inner cylinder remains aggregated as it slides forward in the feeding chute. The second pushing mechanism 30 includes a second pushing member 31, a holding member 32, and a second driving component 33; the second driving component 33 is used to drive the second pushing member 31 and the holding member 32 to move; the second pushing member 31 and the holding member 32 are both located behind the first pushing member 21.

[0051] When the second pusher 31 and the support 32 are in the initial position, the support 32 and the second pusher 31 are placed one after the other in the feeding slide. The feeding slide in the interval between the two forms the loading space of the inner cylinder. The loading space can just accommodate the inner cylinder of an inner cylinder cake. When the second pusher 31 pushes the inner cylinder in the loading space to move forward along the feeding slide, the support 32 moves forward synchronously.

[0052] When the holding member 32 catches up with the first pushing member 21, the first pushing member 21 and the holding member 32 exit the feeding chute so that the inner cylinder in the loading space merges and gathers with the inner cylinder in front; and after the first pushing member 21 exits the feeding chute, it retracts to the position of the second pushing member 31 and takes over the second pushing member 31 to continue pushing the inner cylinder.

[0053] The feeding device is used to feed the inner cylinders after the cable ties have been removed. The first-level platform 10 is equipped with a feeding chute and a diversion channel 131. The feeding chute is located behind the diversion channel 131, allowing the inner cylinders to move forward along the feeding chute and enter each diversion channel 131. Finally, the diversion channel 131 diverts the inner cylinders forward for loading into molds or fireworks. In some technical solutions, the first-level platform 10 is equipped with a drive device to drive the inner cylinders on it to move forward along the feeding chute; for example, a vibration device. In some technical solutions, the front of the first-level platform 10 is formed by a belt mechanism, with the conveying surface of the belt mechanism forming the platform surface. The drive device for the belt mechanism is a motor.

[0054] The first pushing mechanism 20 includes a first pushing member 21 and a first driving component 22. The first driving component 22 drives the first pushing member 21 to push the inner cylinder from the rear to the front in the feeding chute, so that the inner cylinder in the feeding chute remains in an aggregated state when it slides forward, and is not prone to tipping over.

[0055] The second pushing mechanism 30 is used for feeding the inner cylinder, pushing the newly loaded inner cylinder forward so that it merges and gathers with the inner cylinder in front. The second pushing mechanism 30 includes a second pushing member 31, a holding member 32, and a second driving assembly 33. The second pushing member 31 and the holding member 32 are both located behind the first pushing member 21. During operation, the second driving assembly 33 first drives the second pushing member 31 and the holding member 32 to their initial positions. At this time, the holding member 32 and the second pushing member 31 are placed one in front of the other in the feeding slide. The feeding slide between the two forms the loading space for the inner cylinder, which can be used to load the inner cylinder of an inner cylinder cake. Then, the second pushing member 31 pushes the inner cylinder in the loading space forward along the feeding slide, and the holding member 32 moves forward synchronously, maintaining the constraint of the inner cylinder during the movement. Subsequently, when the holding member 32 catches up with the first pushing member 21, the first pushing member 21 and the holding member 32 exit the feeding chute to allow the inner cylinder in the loading space to converge with the inner cylinder in front. In this action, the holding member 32 can exit the feeding chute before the first pushing member 21. The holding member 32 and the first pushing member 21 exit the feeding chute sequentially, allowing the inner cylinder in the loading space to gradually approach the inner cylinder in front, avoiding excessive gaps that could cause the inner cylinder to tip over. Finally, after exiting the feeding chute, the first pushing member 21 returns to the position of the second pushing member 31 to take over and continue pushing the inner cylinder. Thus, with the cooperation of the first and second pushing mechanisms, one inner cylinder loading is completed. During the loading process, the existing inner cylinders on the first platform and the newly placed inner cylinders in the loading space are both kept sufficiently confined, thereby preventing the inner cylinders from tipping over and ensuring the continuity of the loading process.

[0056] In one embodiment of this application, the second pusher 31 has a transverse protrusion 311 at its front bottom; when the second pusher 31 pushes the inner cylinder, the transverse protrusion 311 contacts the lower part of the inner cylinder, and there is a gap space between the front side of the second pusher 31 and the upper part of the inner cylinder; the first pusher 21 can be inserted into the gap space to take over from the second pusher 31 to continue pushing the inner cylinder. In this design, the first pusher 21 and the second pusher 31 act on the lower and upper parts of the inner cylinder respectively, making the action connection between the first pusher 21 and the second pusher 31 more continuous.

[0057] The first drive assembly 22 is used to drive the first pusher 21 to move, and may include one or more drive units. The drive units may be electric devices, pneumatic devices, etc., such as cylinders or electric cylinders. In one embodiment of this application, the first drive assembly 22 includes two drive units, one of which is used to drive the first pusher 21 to move back and forth, and the other is used to drive the first pusher 21 to move up and down.

[0058] The second drive assembly 33 is used to drive the second pusher 31 and the support member 32 to move. It may include one or more drive units, which may be electric devices, pneumatic devices, etc., such as cylinders or electric cylinders. In one embodiment of this application, the second drive assembly 33 includes two drive units, one of which is used to drive the second pusher 31 and the support member 32 to move back and forth, and the other is used to drive the support member 32 to move up and down.

[0059] In one embodiment of this application, a first loading port 114 is provided on the first-layer platform 10; when the second pusher 31 and the support 32 are in their initial positions, the first loading port 114 is located at the bottom of the loading space. (See reference...) Figure 6 and Figure 7 The feeding device also includes a second-level platform 40, a variable material frame mechanism 50, and a first lifting mechanism 60. (Reference) Figure 1 and Figure 2 The second platform 40 is located below the first platform 10 and can be used to vertically place the inner cylinder.

[0060] The variable material frame mechanism 50 includes a frame assembly 51, a third drive assembly 52, and a fourth drive assembly 53. The frame assembly 51 is located on the second-level platform 40. The frame assembly 51 includes multiple enclosure members, which together on the second-level platform 40 to form a variable material trough 511. In one specific technical solution, the frame assembly 51 has six enclosure members; when the variable material trough 511 transforms into a hexagonal state, its six sides correspond one-to-one with the six enclosure members.

[0061] The third drive assembly 52 is used to drive the enclosure to change the variable material trough 511 into a hexagonal or rectangular state; in the hexagonal state, the variable material trough 511 matches the shape of the inner cylinder cake so that the inner cylinder of an inner cylinder cake can be completely inserted into the variable material trough 511; in both the rectangular and hexagonal states, the variable material trough 511 can just accommodate the inner cylinder of an inner cylinder cake.

[0062] The fourth drive assembly 53 can drive the frame assembly 51 to move to the first position or the second position on the second platform 40; when the frame assembly 51 moves to the first position, the variable material trough 511 changes into a rectangular state and aligns with the first feeding port 114, and the first lifting mechanism 60 can lift the inner cylinder in the variable material trough 511 from the bottom into the loading space; when the frame assembly 51 moves to the second position, the variable material trough 511 changes into a hexagonal state so that the inner cylinder can be loaded.

[0063] The third drive assembly 52 is used to drive the frame assembly 51 to change shape, and the fourth drive assembly 53 is used to drive the frame assembly 51 to move. The third drive assembly 52 may include one or more drive units, which are used to drive the enclosure component. These drive units can be electric devices, pneumatic devices, etc., such as cylinders or electric cylinders. Alternatively, the drive unit can be an elastic element; the elastic force applied to the enclosure component by the elastic element can also drive the enclosure component to move. Specifically, the elastic element can be a spring. The fourth drive assembly 53 may include one or more drive units, which can be electric devices, pneumatic devices, etc., such as cylinders or electric cylinders. The first lifting mechanism 60 may include a lifting head and a drive device, which drives the lifting head to move up and down. The drive device can be a cylinder, electric cylinder, etc.

[0064] During operation, the fourth drive assembly 53 drives the frame assembly 51 to move on the second-level platform 40. When the fourth drive assembly 53 drives the frame assembly 51 to the first position, the third drive assembly 52 drives the enclosure to transform the variable material trough 511 into a rectangular state, aligning it with the first loading port 114 of the first-level platform 10. At this time, the first lifting mechanism 60 can lift the inner cylinder in the variable material trough 511 from the bottom into the loading space. When the fourth drive assembly 53 drives the frame assembly 51 to the second position, the variable material trough 511 transforms into a hexagonal state. At this time, the inner cylinder of an inner cylinder cake can be loaded into the variable material trough 511. In this design, the inner cylinder of the hexagonal inner cylinder cake is loaded into the variable material trough as a whole, and finally transforms into a rectangular state and outputs it into the loading space. The pushing mechanism pushes the inner cylinder forward along the first-level platform. After the inner cylinder is transformed into a rectangular distribution, the inner cylinder is less likely to tip over during the pushing and merging process.

[0065] In one embodiment of this application, a second loading port 41 is provided on the second-layer platform 40; when the frame assembly 51 moves to the second position, the variable feed trough 511 aligns with the second loading port 41. (See reference...) Figure 8 The feeding device also includes a third-level platform 70, a moving material frame mechanism 80, and a second lifting mechanism 90. (Reference) Figure 1 and Figure 2 The third platform 70 is located below the second platform 40 and can be used to vertically place the inner cylinder.

[0066] The moving material frame mechanism 80 includes a moving material frame 81 and a fifth drive component 82; the moving material frame 81 is located on the third layer platform 70 and forms a material trough 811 on the third layer platform 70; the material trough 811 is hexagonal and can just accommodate the inner cylinder of an inner cylinder cake.

[0067] The fifth drive assembly 82 can drive the movable material frame 81 to move to the third position or the fourth position on the third platform 70; when the movable material frame 81 moves to the third position, the material trough 811 is aligned with the second feeding port 41, and the second lifting mechanism 90 can lift the inner cylinder in the material trough 811 into the variable material trough 511; when the movable material frame 81 moves to the fourth position, the inner cylinder is inserted; when the movable material frame 81 is in the fourth position, the inner cylinder is inserted.

[0068] The fifth drive assembly 82 is used to drive the moving material frame 81 to move, and may include one or more drive units. The drive units are used to drive the enclosure components and may be electric devices, pneumatic devices, etc., such as cylinders or electric cylinders. The second lifting mechanism 90 may include a lifting head and a drive device, which drives the lifting head to move up and down. The drive device may be a cylinder, electric cylinder, etc.

[0069] During operation, the fifth drive assembly 82 drives the moving material frame 81 to move on the third-level platform 70. When the fifth drive assembly 82 drives the moving material frame 81 to the fourth position, the inner cylinder of an inner cylinder cake can be loaded into the moving material frame 81. When the fifth drive assembly 82 drives the moving material frame 81 to the third position, the material trough 811 is aligned with the second feeding port 41, and the second lifting mechanism 90 can lift the inner cylinder in the material trough 811 into the variable material trough 511.

[0070] In one embodiment of this application, the first-layer platform 10 is sequentially divided into a first region 11, a second region 12, and a third region 13 from front to back; wherein, a diversion channel 131 is arranged in the third region 13, and a feeding chute is arranged in the first region 11 and the second region 12. A first baffle 111 and a second baffle 112 are arranged on the first region 11, the first baffle 111 and the second baffle 112 being parallel to each other and forming a rear section 113 of the feeding chute between them; a first feed port 114 is arranged in the rear section 113 of the feeding chute. A third baffle 121 and a fourth baffle 122 are arranged on the second region 12, forming a front section 123 of the feeding chute between the third baffle 121 and the fourth baffle 122. A first pusher 21, a second pusher 31, and a support 32 are all located in the rear section 113 of the feeding chute and are matched with the width of the rear section 113 of the feeding chute.

[0071] The diversion channel 131 is arranged in the third region 13 and is divided by multiple baffles spaced apart in the third region 13. Behind the diversion channel 131 are the front section 123 and the rear section 113 of the feeding chute, wherein the front section 123 of the feeding chute is located between the diversion channel 131 and the rear section 113 of the feeding chute. The first feed port 114 is arranged in the rear section 113 of the feeding chute and is used to load the inner cylinder into the rear section 113 of the feeding chute.

[0072] exist Figure 4 In the structure shown, the feed chute includes a rear section 113 and a front section 123. The side rails include a first side rail 111, a second side rail 112, a third side rail 121, and a fourth side rail 122. The first side rail 111 and the second side rail 112 are parallel to each other; therefore, the rear section 113 is a straight chute with a uniform width. The third side rail 121 and the fourth side rail 122 are in an expanded state. The side of the front section 123 that connects with the rear section 113 is narrower, while the side of the front section 123 that connects with the diversion channel 131 is wider.

A first region 11 and a second region 12 are arranged on the front platform support, and a third region 13 is arranged on the rear platform support. The front platform support is equipped with a vibration component, which is used to apply vibration to the front platform support to move the inner cylinders on the first region 11 and the second region 12 forward.

[0074] This application embodiment also provides a method for feeding fireworks inner tubes. The feeding method is applied to the feeding device provided in the previous part and includes the following steps 101-103.

[0075] Step 101: The first drive assembly 22 drives the first pusher 21 to push the inner cylinder in the feed chute from the rear to the front, so that the inner cylinder in the feed chute remains in an aggregated state when it slides forward.

[0076] In step 102, the second drive assembly 33 drives the second pusher 31 and the guard 32 to the initial position. The guard 32 and the second pusher 31 are placed one after the other in the feeding slide, and the feeding slide section between them forms a loading space for loading the inner cylinder. Furthermore, when the second pusher 31 pushes the inner cylinder in the loading space forward along the feeding slide under the drive of the second drive assembly 33, the guard 32 moves forward synchronously.

[0077] Step 103: When the guard 32 catches up with the first pusher 21, the first pusher 21 and the guard 32 exit the feed chute so that the inner cylinder in the loading space merges and gathers with the inner cylinder in front; and after the first pusher 21 exits the feed chute, it retracts to the position of the second pusher 31 and takes over from the second pusher 31 to continue pushing the inner cylinder.

[0078] Based on steps 101-103 above, the second drive assembly 33 first drives the second pusher 31 and the holder 32 to their initial positions. At this time, the holder 32 and the second pusher 31 are positioned one after the other in the feeding chute. The feeding chute, in the space between the two, forms the loading space for the inner cylinder, into which the inner cylinder of an inner cylinder cake can be loaded. Next, the second pusher 31 pushes the inner cylinder in the loading space forward along the feeding chute, while the holder 32 moves forward synchronously, maintaining the constraint on the inner cylinder during the movement. Subsequently, when the holding member 32 catches up with the first pushing member 21, the first pushing member 21 and the holding member 32 exit the feeding chute to allow the inner cylinder in the loading space to converge with the inner cylinder in front. In this action, the holding member 32 can exit the feeding chute before the first pushing member 21. The holding member 32 and the first pushing member 21 exit the feeding chute sequentially, allowing the inner cylinder in the loading space to gradually approach the inner cylinder in front, avoiding excessive gaps that could cause the inner cylinder to tip over. Finally, after exiting the feeding chute, the first pushing member 21 returns to the position of the second pushing member 31 to take over and continue pushing the inner cylinder. Thus, with the cooperation of the first and second pushing mechanisms, one inner cylinder loading is completed. During the loading process, the existing inner cylinders on the first platform and the newly placed inner cylinders in the loading space are both kept sufficiently confined, thereby preventing the inner cylinders from tipping over and ensuring the continuity of the loading process.

[0079] In this feeding method, both the original inner cylinder on the first-level platform and the newly placed inner cylinder in the loading space are kept sufficiently confined during the feeding process, thereby preventing the inner cylinder from tipping over and ensuring the continuity of the feeding process.

[0080] In one embodiment of this application, the feeding method further includes steps 201 and 202.

[0081] In step 201, the fourth drive component 53 drives the frame component 51 to move to the second position, and the third drive component 52 drives the enclosure component to change the variable material trough 511 into a hexagonal state so as to load the inner cylinder.

[0082] In step 202, when the second drive assembly 33 drives the second pusher 31 and the guard 32 to move to the initial position, the fourth drive assembly 53 drives the frame assembly 51 to move to the first position, and the third drive assembly 52 drives the enclosure to move so that the variable material trough 511 is transformed into a rectangular state and aligned with the first loading port 114 of the first layer platform 10. At this time, the first lifting mechanism 60 can lift the inner cylinder in the variable material trough 511 from the bottom into the loading space.

[0083] In one embodiment of this application, the feeding method further includes steps 301 and 302.

[0084] Step 301: The fifth drive component 82 drives the moving material frame 81 to the fourth position to load the inner cylinder.

[0085] Step 302: When the fourth drive component 53 drives the frame component 51 to move to the second position, and the third drive component 52 drives the enclosure component to change the variable material trough 511 into a hexagonal state, the fifth drive component 82 drives the moving material frame 81 to move to the third position, the material trough 811 is aligned with the second feeding port 41, and the second lifting mechanism 90 lifts the inner cylinder in the material trough 811 into the variable material trough 511.

[0087] This application also provides a production equipment for combined fireworks, including the aforementioned feeding device. The feeding device includes a first platform 10, a first pushing mechanism 20, and a second pushing mechanism 30. The first platform 10 is capable of vertically placing the inner cylinder; multiple transversely arranged diversion channels 131 are arranged in the area near the front of the first platform 10, the diversion channels 131 being used to divert the inner cylinder forward; baffles are arranged on both sides behind the diversion channels 131, and a feeding slide is formed between the baffles on both sides for the inner cylinder to slide forward; the feeding slide connects to each diversion channel 131 to guide the inner cylinder into each diversion channel 131. The first pushing mechanism 20 has a first pushing member 21 for pushing the inner cylinder and a first driving assembly 22; the first driving assembly 22 is used to drive the first pushing member 21 to move; the first pushing member 21 is used to push the inner cylinder from the rear of the inner cylinder forward in the feeding slide, so that the inner cylinder in the feeding slide remains in an aggregated state when sliding forward. The second pushing mechanism 30 includes a second pushing member 31, a supporting member 32, and a second driving component 33. The second driving component 33 is used to drive the second pushing member 31 and the supporting member 32 to move. The second pushing member 31 and the supporting member 32 are both located behind the first pushing member 21. When the second pushing member 31 and the supporting member 32 are in the initial position, the supporting member 32 and the second pushing member 31 are placed one in front of the other in the feeding chute. The feeding chute in the interval between the two forms the loading space of the inner cylinder, which can just accommodate the inner cylinder of one inner cylinder cake. When the second pushing member 31 pushes the inner cylinder in the loading space forward along the feeding chute, the supporting member 32 moves forward synchronously. When the holding member 32 catches up with the first pushing member 21, the first pushing member 21 and the holding member 32 exit the feeding chute so that the inner cylinder in the loading space merges and gathers with the inner cylinder in front; and after the first pushing member 21 exits the feeding chute, it retracts to the position of the second pushing member 31 and takes over the second pushing member 31 to continue pushing the inner cylinder.
