Description

Technical Field

[0001] This invention relates to the field of mechanical technology, and in particular to a fully automatic firecracker insertion machine. Background Technology

[0002] Traditional firecracker production has long relied on manual insertion. Firecracker tubes are typically arranged in an array, then bound together with ties to form firecracker cakes. Workers then manually complete the entire process, including placing the firecracker cakes, arranging the tubes, cutting the fuse, manually inserting the fuse, and unloading the finished product. This method is not only labor-intensive and inefficient, but also heavily dependent on worker skill, resulting in inconsistent product quality and a high defect rate. To address the drawbacks of manual production, various semi-automatic and fully automatic firecracker insertion machines have gradually emerged, replacing manual operation to some extent and improving basic production efficiency. However, existing equipment still suffers from several core technological deficiencies in practical applications, lacking adaptability and stability. Most existing insertion machines lack fully automatic loading and unloading capabilities, requiring manual assistance for loading and unloading, thus failing to achieve continuous automated material flow. Alternatively, existing insertion machines cannot smoothly move the firecracker cakes on an automated line, often requiring flipping between different mechanisms in continuous operation. This can easily cause deformation or misalignment of the firecracker cakes or tubes, affecting subsequent processes. Summary of the Invention

[0021] Traditional firecracker production has long relied on manual fuse insertion. Firecracker tubes are typically arranged in an array and then bound together with ties to form firecracker cakes. Workers then manually complete the entire process, including placing the firecracker cakes, arranging the tubes, cutting the fuses, manually inserting the fuses, and unloading the finished product. This method is not only labor-intensive and inefficient, but also heavily dependent on worker skill, resulting in inconsistent product quality and a high defect rate. To address the drawbacks of manual production, various semi-automatic and fully automatic firecracker fuse insertion machines have gradually emerged, replacing manual operation to some extent and improving basic production efficiency. However, most existing insertion machines lack fully automatic loading and unloading capabilities, requiring manual assistance for loading and unloading, thus failing to achieve continuous automated material flow. Alternatively, existing insertion machines may not be able to move the firecracker cakes horizontally on an automated line, often requiring the cakes to be flipped between continuously operating mechanisms. This can easily cause deformation or misalignment of the firecracker cakes or tubes, affecting the normal operation of subsequent processes.

[0022] Based on this, please refer to Figure 1-5This application provides a fully automatic firecracker insertion machine, including: a frame and a transport mechanism 10 and an insertion mechanism 40 mounted on the frame. The transport mechanism 10 is provided with a feeding module 11, a handling module 12 and a discharging module 13; the feeding module 11 is provided with a feeding platform 111 and a first lifting component 112 located at the discharging end of the feeding platform 111; the discharging module 13 is provided with a discharging platform 131 and a second lifting component 132 located at the feeding end of the discharging platform 131; the handling module 12 is located above the feeding module 11 and the discharging module 13, and is provided with a handling platform 121 and a translation component 122 for moving the firecracker pellets 200. The first lifting assembly 112 and the second lifting assembly 132 are respectively located at both ends of the conveying platform 121, and the insertion mechanism 40 is located in the middle of the conveying platform 121. The first lifting assembly 112 moves up and down between the feeding platform 111 and the conveying platform 121, and the second lifting assembly 132 moves between the discharging platform 131 and the conveying platform 121 to feed the firecracker cake 200 through the feeding module 11, then transport it to the insertion mechanism 40 for insertion, and then discharge it through the discharging module 13, thus completing the fully automatic insertion of the firecracker cake 200.

[0023] This embodiment of the application sets up two sets of lifting modules, dividing the front and rear feeding and unloading processes and the middle insertion process into upper and lower sections. Only the translation component 122 is needed to transfer the firecracker cake 200 in the middle, simplifying the structure of the middle handling module 12. The firecracker cake maintains stable translation between each station from loading to unloading without flipping, which can improve the operation accuracy of the insertion process and improve the structural stability of the firecracker cake 200.

[0024] Specifically, please refer to Figure 1 and Figure 3 The first lifting assembly 112 includes a first lifting drive 1121 and a first lifting platform 1122. The fixed end of the first lifting drive 1121 is fixed to the frame or the feeding platform 111. The first lifting platform 1122 is located at the output end of the first lifting drive 1121. After the firecracker cake 200 enters the feeding platform 111, it is transported to the first lifting platform 1122. The first lifting drive 1121 drives the first lifting platform 1122 to rise to the same level as the transport platform 121. At this time, the translation assembly 122 clamps the firecracker cake 200 to the subsequent work station.

[0025] Furthermore, in some embodiments, the feeding module 11 further includes a first feeding component 113 and a second feeding component 114 respectively disposed at the feeding end and the discharging end of the feeding platform 111. The first feeding component 113 includes a first feeding drive 1132 fixed to the feeding platform 111 and a first pusher 1131 disposed at the output end of the first feeding drive 1132; the second feeding component 114 includes a second feeding drive 1142 and a second pusher 1141 disposed at the output end of the second feeding drive 1142. When the firecracker cake 200 is fed from the feeding platform 111, it is pushed from the feeding end to the discharging end by the first pusher 1131 until it abuts against the second pusher 1141. At this time, the firecracker cake 200 is located on the first lifting platform 1122.

[0026] Furthermore, the first feeding assembly 113 also includes a third feeding drive 1133. One end of the third feeding drive 1133 is connected to the output end of the first feeding drive 1132, and the other end is connected to the first pusher 1131, so as to drive the first pusher 1131 closer to or further away from the feeding platform 111. In this embodiment, by setting the third feeding drive 1133, it is possible to adjust the first pusher 1131 to always abut against the middle of the firecracker cake 200, so that the firecracker cake 200 is subjected to uniform force.

[0027] Specifically, please refer to Figure 1 and Figure 4 The second lifting assembly 132 includes a second lifting drive 1321 and a second lifting platform 1322. The fixed end of the second lifting drive 1321 is fixed to the frame or the discharge platform 131, and the second lifting platform 1322 is located at the output end of the second lifting drive 1321. After the firecracker is inserted, the translation assembly 122 moves the firecracker cake 200 to the position of the second lifting platform 1322. Then, the second lifting drive 1321 moves the second lifting platform 1322 down to be level with the discharge platform 131, and then the firecracker cake 200 is unloaded.

[0028] Furthermore, in some embodiments, the discharge module 13 further includes a discharge drive 1332 and a third pusher 1331 disposed at the feeding end of the discharge platform 131. The fixed end of the discharge drive 1332 is fixed to the frame or the discharge platform 131, and the third pusher 1331 is disposed at the output end of the discharge drive 1332. The discharge drive 1332 drives the third pusher 1331 to push the firecracker cakes 200 on the second lifting platform 1322 to the discharge end of the discharge platform 131 for unloading.

[0029] Further, please refer to Figure 1 , Figure 2 and Figure 5In this embodiment, the feeding end of the conveying platform 121 is provided with a feeding hole 1211 corresponding to the position of the first lifting platform 1122. The translation component 122 is located above the feeding hole 1211. The first lifting platform 1122 rises to be flush with the conveying platform 121, and the translation component 122 clamps and transfers the firecracker cake 200 to the next station. The discharging end of the conveying platform 121 is provided with a discharging hole 1212 corresponding to the position of the second lifting platform 1322. The translation component 122 clamps the inserted firecracker cake 200 onto the second lifting platform 1322 embedded in the discharging hole 1212, and then the second lifting platform 1322 descends to transfer the firecracker cake 200 to the discharging module 13.

[0030] Please see Figure 5 Furthermore, in some embodiments, the translation assembly 122 includes a first translation drive 1222, a translation seat plate 1221, and two sets of translation clamping plates 1223 disposed on the transport platform 121. The first translation drive 1222 is disposed along the feed end of the transport platform 121 toward its discharge end, and the translation seat plate 1221 is disposed at the output end of the first translation drive 1222. The translation seat plate 1221 has a cut in the middle for accommodating the firecracker cake 200. As an example, the translation seat plate 1221 is Y-shaped. The two translation clamping plates 1223 are disposed opposite to each other and slidably connected to the two ends of the translation seat plate 1221. The two translation clamping plates 1223 move closer to or further away from each other to clamp or release the firecracker cake.

[0031] Specifically, the translation component 122 is also provided with a second translation drive 1224. The fixed end of the second translation drive 1224 is fixed to the translation base plate 1221, and its output end is connected to the translation clamping plate 1223 to drive the translation clamping plate 1223 to clamp or release the firecracker cake 200.

[0032] Please see Figure 1 , Figure 3 , Figure 6 and Figure 7Furthermore, the fully automatic firecracker insertion machine also includes a first shaping mechanism 20, which is located in the middle of the feeding platform 111 and includes a first shaping base plate 21 and a first shaping module 22. The first shaping base plate 21 is embedded in the feeding platform 111 and is coplanar with the feeding platform 111, and the firecracker cake 200 is placed on the first shaping base plate 21. The first shaping module 22 includes a first shaping support frame 223, and an upper pressing component 221 and a lower pressing component 222 respectively disposed above and below the first shaping base plate 21, which are mounted on the first shaping support frame 223. The upper pressing component 221 has an upper pressing plate 2212 and upper shaping blocks 2211 spaced apart on the outer periphery of the upper pressing plate 2212. The pressing assembly 222 includes a pressing plate 2222 and lower shaping blocks 2221 spaced around the outer periphery of the pressing plate 2222. The upper shaping blocks 2211 and lower shaping blocks 2221 are respectively positioned opposite the upper and lower end faces of the tie 201. During the shaping process, the upper shaping blocks 2211 and lower shaping blocks 2221 clamp and position the tie 201 from its upper and lower end faces. This configuration allows for adjustment and correction of the overall shape of the firecracker disc 200 and the position of the tie 201 before the hole-expanding and shaping process, preventing misalignment of the firecracker body and facilitating subsequent hole-expanding, shaping, and insertion processes, thus improving the safety of the firecracker disc.

[0033] Understandably, the upper pressing assembly 221 also includes an upper shaping drive 2214. The upper pressing plate 2212 is fixed to the output end of the upper shaping drive 2214. The upper shaping drive 2214 drives the upper pressing plate 2212 to move from top to bottom until it abuts against the upper surface of the firecracker cake 200. The upper shaping block 2211 abuts against the upper end face of the tie 201 from top to bottom. The lower pressing assembly 222 also includes a lower shaping drive 2223. The lower pressing plate 2222 is fixed to the output end of the lower shaping drive 2223. The lower shaping drive 2223 drives the lower pressing plate 2222 and the lower shaping block 2221 to move from bottom to top until the lower shaping block 2221 abuts against the lower end face of the tie 201.

[0034] Please see Figure 3 , Figure 6 and Figure 7 Furthermore, in some embodiments, the first shaping plate 21 is provided with a first positioning hole 211, which is located below the tie 201. The lower shaping block 2221 passes through the first positioning hole 211 and abuts against the lower end face of the tie 201. It can be understood that by setting an independent first shaping plate 21 on the conveyor line of the firecracker cake 200, if different sizes of firecracker cakes 200 need to be replaced in subsequent production processes, only the first shaping plate 21 needs to be replaced, without replacing or adjusting the product conveyor line, thus improving equipment adaptability.

[0035] Furthermore, in some embodiments, the upper pressing assembly 221 further includes a plurality of spaced upper pressing blocks 2213 disposed on the upper pressing plate 2212. The upper pressing blocks 2213 cover the outer edge of the firecracker cake 200 and are used to press down the firecracker tube 202 near the tie 201 to fix the relative position of the tie 201 and the firecracker tube 202.

[0036] Furthermore, the upper shaping block 2211 includes a horizontally arranged first pressing part and a protruding second pressing part. The first pressing part is fixed to the upper pressure plate 2212 and is coplanar with the upper pressure block 2213, together surrounding and completely covering the outer periphery of the firecracker cake 200. The second pressing part presses the tie 201 to a fixed position to further and accurately fix the relative position of the tie 201 and the firecracker tube 202.

[0037] Furthermore, in some embodiments, the first shaping mechanism 20 further includes a positioning module 23, which includes a stop component 231 disposed in the running direction of the firecracker cake 200. The stop component 231 is provided with a stop drive 2312 and a stop block 2311 disposed at the output end of the stop drive 2312. The stop block 2311 is movably disposed in front of the firecracker cake 200 in the conveying direction. During the feeding process, the first pusher 1131 pushes the firecracker cake 200 to abut against the stop block 2311 for shaping.

[0038] Furthermore, in some embodiments, the first shaping base plate 21 is provided with a second positioning hole 212 for the stop block 2311 to pass through, and the stop drive member 2312 is located below the first shaping base plate 21. Its output end drives the stop block 2311 to pass through the second positioning hole 212 and abut against the firecracker cake 200, thereby fixing the firecracker cake 200 at the first shaping station.

[0039] Furthermore, in some embodiments, the positioning module 23 further includes side pressure components 232 disposed on both sides of the firecracker cake 200 in the direction of travel. The side pressure components 232 include a side pressure drive 2322 and a side pressure block 2321 disposed at the output end of the side pressure drive 2322. The side pressure block 2321 is clamped on the opposite sides of the firecracker cake 200.

[0040] During the shaping process prior to the reaming, the first pusher 1131 first pushes the firecracker cake 200 onto the first shaping base plate 21. At this time, the stop drive 2312 drives the stop block 2311 to protrude from the first shaping base plate 21 through the second positioning hole 212, and the first pusher 1131 pushes the firecracker cake 200 to abut against the stop block 2311. Next, the side pressure assembly 232 operates, and the side pressure drive 2322 drives the side pressure block 2321 to clamp the opposite sides of the firecracker cake 200 from both sides. At this time, the firecracker cake 200 is fixed on the first shaping base plate 21. Then, the upper shaping drive 2214 drives the upper pressure plate 2212 and the upper shaping block 2211 to move from top to bottom until the upper pressure block 2213 abuts against the edge of the firecracker. At this time, the upper shaping block 2211 pushes the tie 201 to a fixed height from above. At the same time, the lower shaping drive 2223 drives the lower pressure plate 2222 and the lower shaping block 2221 to move upward until the upper shaping block 2211 passes through the first positioning hole 211 and abuts against the tie 201, pushing the tie 201 to a fixed height. At this time, the upper shaping block 2211 and the lower shaping block 2221 abut against the upper and lower end faces of the tie 201, pushing the tie 201 to the fixed position of the firecracker tube 202.

[0041] Please see Figure 1 and Figure 8 Furthermore, the fully automatic firecracker insertion machine also includes a second shaping mechanism 30, which is fixed on the frame and located downstream of the first shaping mechanism 20, for expanding and shaping the firecracker tube 202.

[0042] Specifically, the second shaping mechanism 30 includes a second shaping module 31 and a second shaping support frame 32. The second shaping module 31 is mounted above the transport platform 121 via the second shaping support frame 32. The second shaping module 31 includes a first hole-expanding drive 311, a first needle plate clamping plate 312 located at the output end of the first hole-expanding drive 311, and hole-expanding needles 315 arrayed on the first needle plate clamping plate 312. The hole-expanding needles 315 are positioned directly opposite the firecracker tube 202.

[0043] Furthermore, in some embodiments, the second shaping module 31 further includes a second hole-expanding drive 313 and a second needle plate clamping plate 314 disposed at the output end of the second hole-expanding drive 313. The fixed end of the second hole-expanding drive 313 is fixedly connected to the first needle plate clamping plate 312. The second needle plate clamping plate 314 is disposed below the first needle plate clamping plate 312 and is provided with a plurality of needle holes for protecting the free end of the hole-expanding needle 315 and guiding the hole-expanding needle 315 during the shaping process.

[0044] During the secondary shaping of the firecracker tube 202, the firecracker disc 200 is transported to the lower part of the second shaping module 31 via the translation component 122. At this time, the first hole-expanding drive component 311 drives the first needle plate clamping plate 312 to move downwards towards the firecracker disc 200 until the second needle plate clamping plate 314 abuts against the upper end surface of the firecracker disc 200. Then, the first hole-expanding drive component 311 and the second hole-expanding drive component 313 work simultaneously. The second needle plate clamping plate 314 is fixedly set on the upper end surface of the firecracker disc 200, and the hole-expanding needle 315 continues to move downwards, extending out of the needle hole of the second needle plate clamping plate 314 and entering the firecracker tube 202 to expand and shape the firecracker tube 202.

[0045] Please see Figure 1 and Figure 9-13 Furthermore, in some embodiments, the insertion mechanism 40 includes an insertion module 41 and a guide sleeve assembly 42 for introducing leads; the guide sleeve assembly 42 is provided with a slidingly connected insertion frame 421 and a baffle 422, the insertion frame 421 is provided with a plurality of arrayed lead holes 4211, and the baffle 422 is provided with a lower wire hole 4221 corresponding to the lead hole 4211, and the insertion frame 421 and the baffle 422 are relatively displaced to make the lead hole 4211 and the lower wire hole 4221 connected or misaligned.

[0046] The insertion module 41 is fixed to the frame and includes an insertion displacement component 412 and a first clamping component 413. The insertion displacement component 412 is fixed to the frame, and the first clamping component 413 is movably located at the output end of the insertion displacement component 412 to clamp the guide sleeve component 42, which is then moved by the insertion displacement component 412 to the top of the firecracker cake 200. In this configuration, the lead wire is pre-cut into the insertion frame 421, at which point the lead wire hole 4211 and the lower lead wire hole 4221 are misaligned, and the lower end of the lead wire hole 4211 is blocked. After the insertion module 41 moves the guide sleeve component 42 to the top of the firecracker cake 200, the insertion frame 421 and the baffle 422 slide relative to each other, and the lead wire hole 4211 and the lower lead wire hole 4221 become connected. The lead wire falls through the lower lead wire hole 4221 into the firecracker tube 202 of the firecracker cake 200 below, thus completing the insertion of the firecracker cake 200 in one go.

[0047] It is understood that the guide sleeve assembly 42 can be pre-cut by the lead cutter 300 outside the insertion mechanism 40, and the lead cutter 300 can be set next to the insertion mechanism 40. Alternatively, the guide sleeve assembly 42 can have a lead wire pre-inserted on the outside, and then be continuously transported to the insertion mechanism 40 by loading / unloading or a production line. Its function is to pre-cut the lead wire and then insert the firecracker cake 200 in one go through the guide sleeve assembly 42. There are no restrictions on this.

[0048] Furthermore, in some embodiments, the guide sleeve assembly 42 is also provided with a connector 423, which is fixed to both ends of the baffle 422 and is provided with a sliding groove 4231. The two ends of the insertion frame 421 are slidably inserted into the sliding groove 4231 and can slide relative to the baffle 422 so that the lead hole 4211 and the lower wire hole 4221 are connected or misaligned.

[0049] Furthermore, in some embodiments, the connector 423 is provided with a first clamping hole 4232, and the first clamping assembly 413 is provided with a first clamping claw 4132, which is inserted into the first clamping hole 4232 to clamp the guide sleeve assembly 42.

[0050] Specifically, the insertion module 41 is further provided with an insertion support frame 411 fixed to the frame, and an insertion displacement assembly 412 is disposed on the insertion support frame 411. The insertion displacement assembly 412 includes a first insertion drive 4121, a first support plate 4122, a second insertion drive 4123, a second support plate 4124, and a third insertion drive 4125; the fixed end of the first insertion drive 4121 is connected to the insertion support frame 411, and its output end is connected to the first support plate 4122; the first support plate 4122 is slidably connected to the insertion support frame 411; the fixed end of the second insertion drive 4123 is connected to the first support plate 4122, and its output end is connected to the second support plate 4124, so as to drive the second support plate 4124 to rise and fall; the fixed end of the third insertion drive 4125 is fixed to the second support plate 4124, and its output end is connected to the first gripper 4132. In this configuration, the first insertion drive 4121 drives the first support plate 4122 at its output end to slide horizontally relative to the insertion support frame 411, thereby causing the guide sleeve assembly 42 held by the first gripper 4132 to move horizontally. The second insertion drive 4123 is used to drive the guide sleeve assembly 42 held by the first gripper 4132 to rise or fall to adjust the distance between the guide sleeve assembly 42 and the firecracker cake 200. The third insertion drive 4125 drives the first grippers 4132 to move closer or further apart to grip or release the guide sleeve assembly 42. It is understood that the first gripper 4132 is connected to the output end of the third insertion drive 4125 through the gripping arm 4131, which will not be described in detail here.

[0051] Furthermore, in some embodiments, the insertion module 41 further includes a first pusher 414 and a second pusher 415 disposed opposite to each other. The first pusher 414 and the second pusher 415 are respectively disposed at the two ends of the insertion frame 421 in the sliding direction, and are used to push the insertion frame 421 to slide misaligned or reset relative to the baffle 422.

[0052] Preferably, in this embodiment, the first pushing member 414 is disposed on the second support plate 4124, and is driven to move synchronously with the guide sleeve assembly 42 by the first insertion driving member 4121 and the second insertion driving member 4123. This allows the first pushing member 414 and the guide sleeve assembly 42 to maintain a fixed relative position. The second pushing member 415 is disposed on the translation base plate 1221, and moves synchronously with the translation assembly 122. This allows the second pushing member 415 and the firecracker cake 200 to maintain a fixed relative position, avoiding problems such as improper insertion caused by misalignment of the first pushing member 414, the second pushing member 415, and the guide sleeve assembly 42.

[0053] Furthermore, the insertion mechanism 40 also includes an upward drawing module 43 fixed to the frame. The upward drawing module 43 and the insertion module 41 are respectively located on both sides of the translational trajectory of the firecracker cake 200 on the transport platform 121. The upward drawing module 43 is provided with a support assembly 432. The support assembly 432 is provided with a first rotary drive member 4321 and a plurality of second clamping assemblies 433 for clamping the guide sleeve assembly 42. The plurality of second clamping assemblies 433 are spaced apart at the output end of the first rotary drive member 4321 to realize alternating loading and unloading.

[0054] Specifically, the second clamping component 433 is provided with a second clamping claw 4335 at its end, and the connector 423 is also provided with a second clamping hole 4233. The second clamping claw 4335 is inserted into the second clamping hole 4233 from both sides to clamp and move the guide sleeve component 42 for loading and unloading. At this time, the first clamping claw 4132 is disengaged from the first clamping hole 4232, realizing the alternating clamping of the guide sleeve component 42 by the first clamping claw 4132 and the second clamping claw 4335.

[0055] Furthermore, the upward drawing module 43 is also provided with an upward drawing support frame 431, which is fixed on the frame, and the first rotary drive member 4321 is disposed on the upward drawing support frame 431. The output end of the first rotary drive member 4321 is provided with a connecting plate 4322, which can be provided with multiple plate ends, and a plurality of second clamping assemblies 433 are disposed at the plate ends. As an example, this embodiment provides two sets of second clamping assemblies 433, which are disposed at the two symmetrical ends of the connecting plate 4322.

[0056] Specifically, the second clamping assembly 433 includes a first clamping drive 4331, a second clamping drive 4332, a second rotation drive 4333, and a third clamping drive 4334; one end of the first clamping drive 4331 is connected to the connecting plate 4322, and the other end is connected to the second clamping drive 4332; the second rotation drive 4333 is located at the output end of the second clamping drive 4332; there are two third clamping drive 4334, which are symmetrically located at the output end of the second rotation drive 4333. In this configuration, the first clamping drive 4331 drives the clamping end to move up and down, the second clamping drive 4332 drives the clamping end to move horizontally, the second rotation drive 4333 drives the second jaw 4335 to adjust the horizontal angle so as to accurately insert into the second clamping hole 4233 to clamp the guide sleeve assembly 42; the third clamping drive 4334 drives the second jaw 4335 to clamp or release the guide sleeve assembly 42.

[0057] In this embodiment, the firecracker cake 200 is fed through the feeding end of the feeding platform 111, and then pushed to the first shaping seat plate 21 by the first pusher 1131 until the firecracker cake 200 abuts against the stop block 2311 for shaping. At this time, the side pressure block 2321 clamps the firecracker cake 200 from both sides to regularize the shape of the firecracker cake 200. Then the upper shaping block 2211 and the lower shaping block 2221 adjust the height of the tie 201 from both ends of the tie 201. After the first shaping is completed, the stop block 2311 returns to its original position below the first shaping base plate 21. At this time, the first pusher 1131 pushes the firecracker cake 200 to abut against the second pusher 1141. The firecracker cake 200 is now located on the first lifting platform 1122. The first lifting platform 1122 then rises to embed into the feeding hole 1211. At this time, the translation component 122 is located above the feeding hole 1211, clamping the firecracker cake 200. Then, the firecracker cake 200 is moved to a position below the second shaping module 31 for secondary shaping. During the secondary shaping process, the second needle plate clamp 314 abuts against the upper surface of the firecracker cake 200, and the expanding needle 315 extends into the firecracker tube 202 to shape the firecracker tube 202.

[0058] After the secondary shaping is completed, the translation component 122 continues to hold the shaped firecracker cake 200 and moves it to the insertion station. During the insertion process, the upper insertion module 43 clamps the pre-inserted lead guide sleeve component 42 with the second gripper 4335 and rotates it close to the insertion module 41. Then, the insertion module 41 clamps the guide sleeve component 42 with the first gripper 4132. The second gripper 4335 releases the guide sleeve component 42. Then, the first gripper 4132 clamps the guide sleeve component 42 above the firecracker cake 200. The second pusher 415 pushes the insertion frame 421 so that the lead hole 4211 of the insertion frame 421 and the lower wire hole 4221 of the baffle 422 are connected. The pre-inserted lead falls into the firecracker tube 202, completing the insertion of the firecracker cake 200. Next, the first pusher 414 pushes the insertion frame 421 to misalign the lead hole 4211 and the lower lead hole 4221. Then, the first gripper 4132 clamps the guide sleeve assembly 42 below the upper lead module 43. After the second gripper 4335 clamps the guide sleeve assembly 42, the first gripper 4132 releases its grip on the guide sleeve assembly 42. Then, the second gripper 4335 drives the guide sleeve assembly 42 to be unloaded.

[0059] The translation component 122 clamps the inserted firecracker pellet 200 onto the second lifting platform 1322 at the discharge end of the conveying platform 121. At this time, the translation component 122 releases its grip on the firecracker pellet 200, and the second lifting platform 1322 lowers the firecracker pellet 200 to the discharge platform 131, where the third pusher 1331 pushes the firecracker pellet 200 for unloading. In this embodiment, fully automatic loading and unloading of the firecracker pellet 200 and the guide sleeve assembly 42 can be achieved, improving the efficiency of firecracker insertion.

[0060] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: (1) By setting up two sets of lifting modules, the front and rear feeding and unloading processes and the middle insertion process are set up in upper and lower sections. Only the translation component is needed to transfer the firecracker cake in the middle, which simplifies the structure and process of the middle handling module. The firecracker cake moves stably between each station from loading to unloading without flipping, which improves the structural stability of the firecracker cake and improves the operation accuracy of the insertion process. (2) Two sets of shaping mechanisms are set up to shape the shape and tie position of the firecracker cake before the firecracker tube is enlarged and shaped, so as to avoid the firecracker tube being offset or misaligned, which is conducive to the smooth progress of subsequent enlargement and shaping and insertion processes, and improves the safety of the firecracker cake. (3) By setting up the upper guide module, the guide sleeve assembly with inserted leads is transferred to the insertion module, and the firecracker cake is inserted at once without having to rotate and insert each section repeatedly, thus improving the insertion efficiency; (4) It can realize fully automatic loading and unloading of firecracker cakes and guide sleeve components, avoid defects such as jamming that may be caused by online cutting, and improve the efficiency of firecracker insertion. (5) The insertion mechanism is equipped with a first gripper and a second gripper respectively in the insertion module and the upper module to achieve alternating clamping of the guide sleeve assembly and realize continuous insertion operation; (6) The second clamping assembly can achieve the rotational clamping of the second jaw and the precise positioning of the guide sleeve assembly by setting the second rotational drive component, so as to achieve stable alternating clamping of the first jaw and the second jaw.

[0061] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and the present invention also intends to include these modifications and variations.
