Description

TECHNICAL FIELD

[0001] The utility model belongs to fireworks production technical field, especially relate to a kind of fireworks inner cylinder cake feeding device and fireworks production line. BACKGROUND

[0002] In the existing fireworks production process, fireworks inner cylinder cake raw materials are stacked in layers by binding with straps to maintain order during transportation and temporary storage. However, when entering the feeding link, the straps need to be removed and the inner cylinder cake needs to be taken out. The existing production method mainly relies on manual strap removal and handling, which not only has high labor intensity and low work efficiency, but also causes great personal injury if an explosion occurs during strap removal. Although some existing automated equipment can remove the straps, it often directly recycles the straps at the pushing position, which causes interference between the strap removal action and the inner cylinder cake pushing action, easily causing jamming or unstable pushing, thereby reducing the stability and overall rhythm of equipment operation. Moreover, the inner cylinder cake after being unbundled is poured into a hopper, and then poured, pushed or simply vibrated to arrange. Since the inner cylinder is light and easy to roll, the pouring or vibration method cannot guarantee the orderly arrangement of the inner cylinder raw materials during transfer, often causing the inner cylinder to tilt, scatter or jam, with low arrangement accuracy, affecting the subsequent automated feeding and assembly link.

[0003] In addition, in the conveying link, the existing technology generally uses a mechanical hand to grasp and transfer the inner cylinder cake. The mechanical hand has high grasping accuracy, but its motion trajectory is complex, the control system cost is high, and since the mechanical hand can only handle one or a small number of inner cylinder cakes at a time, the overall efficiency is limited, which cannot meet the requirements of continuous and high-rhythm production. At the same time, the mechanical hand is easy to cause unstable position of the inner cylinder cake during clamping due to uneven clamping force or posture deviation, and even needs manual assistance for correction, further affecting the automation level. Therefore, how to provide a device to effectively remove the straps of the fireworks inner cylinder cake and reduce the risk of the fireworks inner cylinder during conveying, and safely, efficiently and stably feed the fireworks inner cylinder cake, is a technical problem to be solved in the field.

[0068] The second pushing assembly 5 is arranged above the first pushing assembly 2 and is provided with a second push head 51 at the telescopic end for pushing the firework inner tube 62 in the lifting assembly 4 out layer by layer.

[0069] In this embodiment, a firework inner tube cake feeding device is provided for pushing the bundled firework inner tube cake (for reference Figure 2 and Figure 3 , the firework inner tube cake 6 includes: a binding tape 61 and a layered stacked firework inner tube 62 bundled with the binding tape 61) out layer by layer to complete the feeding of the firework inner tube. In use: the horizontal conveying line and the feeding clamp of the conveying assembly receive and parallelly convey the firework inner tube cake, the firework inner tube cake is stably accommodated in the first cavity, which can ensure the stable posture and layered neatness of the firework inner tube cake during the conveying process, providing accurate positioning for subsequent pushing and clamping; the first pushing assembly is provided with a first push head corresponding to the inner tube cake, which can push the inner tube cake to the clamping assembly after the firework inner tube cake is conveyed to the specified position, and the clamping assembly reliably clamps the firework inner tube cake and the binding tape of the bundled firework inner tube cake during the pushing process to prevent the firework inner tube cake from shifting; then the first pushing assembly continues to push the firework inner tube as a whole to the lifting assembly, and the binding tape of the bundled firework inner tube is completely hung on the first push head to complete the removal of the binding tape; the lifting assembly lifts the firework inner tube after the binding tape is removed to a predetermined height; the second pushing assembly pushes the firework inner tube out layer by layer after the inner tube cake is lifted into position, so that the inner tube cake can be sequentially layered and fed. Compared with the prior art, the bundled firework inner tube cake is directly pushed out layer by layer to complete the feeding in this embodiment, which not only has high automation degree, but also eliminates the need for manual intervention in the entire feeding process, reduces the risk of safety accidents caused by misoperation, accidental touch and static friction, and greatly improves the safety and reliability of the production process. In addition, the firework inner tube cake is conveyed by the horizontal conveying line and clamped and positioned by the clamping assembly, replacing the traditional mechanical hand clamping method. Compared with the mechanical hand, this technical solution does not require complex programming and debugging, avoiding the problems of high manufacturing and maintenance cost, easy loss of zero point after power failure and complicated operation of the mechanical hand, thereby realizing a simplified structure, stable operation and low-cost feeding process. In summary, the binding tape of the firework inner tube cake is effectively removed, the risk of the firework inner tube during the conveying process is reduced, and the firework inner tube cake is safely, efficiently and stably fed.

[0070] Preferably, referring to Figure 1 , Figure 4 and Figure 5 , the horizontal conveying line 11 is provided with a sensing part 111, and the feeding clamp 12 is provided with a sensing part 122 opposite to the sensing part 111;

[0071] When the sensing part 122 is opposite to the sensing part 111, the first cavity 122 of the feeding clamp 12 is opposite to the first push head 21 of the first push assembly 2.

[0072] In this embodiment, the sensing part is arranged on the horizontal conveying line, and the sensing part opposite to the sensing part is arranged on one side of the feeding clamp. When the sensing part is opposite to the sensing part, the first cavity of the feeding clamp is opposite to the first push head of the first push assembly. This design can realize accurate positioning of the feeding clamp and the push assembly, ensure that the firework inner tube cake is in the correct position when being pushed, avoid jamming, deviation or pushing failure caused by misalignment, thereby improving the reliability and stability of the feeding process, reducing the need for manual adjustment, and further improving the automation degree and production efficiency.

[0073] Preferably, referring to Figure 6 , the clamping assembly 3 comprises: a first clamping part 31 and a second clamping part 32 arranged on both sides of the clamping assembly 3;

[0074] The first clamping part 31 and the second clamping part 32 are symmetrically arranged, and the first clamping part 31 and the second clamping part 32 each comprise an upper clamping block 311, a lower clamping block 312 and a clamping driving part 313;

[0075] The upper clamping block 311 and the lower clamping block 312 are symmetrically arranged at a preset angle;

[0076] The clamping driving part 313 drives the upper clamping block 311 and the lower clamping block 312 to clamp the firework inner tube cake 6.

[0077] In this embodiment, the first clamping part and the second clamping part on both sides of the clamping assembly are symmetrically arranged, and the upper clamping block and the lower clamping block of each clamping part are arranged at a preset angle to form an angular clamping mode under the driving of the clamping driving part. On the one hand, the first clamping part and the second clamping part are structurally identical, so that the clamping process of the firework inner tube cake is uniform in force, avoiding deviation and damage caused by unilateral clamping. On the other hand, the upper clamping block and the lower clamping block are symmetrically arranged at a preset angle, effectively avoiding the problems of slipping or single-point excessive force caused by vertical clamping. It can also more effectively clamp the ribbon around the outer periphery of the firework inner tube cake, so that the ribbon is more effectively removed.

[0078] Preferably, referring to Figure 6The clamping assembly 3 further comprises an upper support block 33 arranged at the top of the clamping assembly 3 and a lower support block 34 arranged at the bottom of the clamping assembly 3.

[0079] The bottom surface of the upper support block 33 is flush with the top of the inner tube cake 6 of the firework.

[0080] The top surface of the lower support block 34 is flush with the bottom surface of the first cavity 121.

[0081] The bottom surface of the upper support block 33 and the top surface of the lower support block 34 are spaced apart and provided with a first protrusion 331.

[0082] In this embodiment, an upper support block and a lower support block are additionally arranged at the top and bottom of the clamping assembly, respectively. The bottom surface of the upper support block is flush with the top of the inner tube cake of the firework, the top surface of the lower support block is flush with the bottom surface of the first cavity, and a first protrusion is arranged between the bottom surface of the upper support block and the top surface of the lower support block. Through the cooperation of the upper and lower support blocks, on the one hand, the inner tube cake of the firework can be limited and supported in the upward and downward directions, and together with the upper clamping block and the lower clamping block, the inner tube cake of the firework and the ribbon can be multi-directionally supported and clamped, further avoiding the upward and downward movement or position deviation of the inner tube cake of the firework during clamping. On the other hand, the lower support block is flush with the bottom surface of the first cavity of the feeding clamp, so that the inner tube cake of the firework pushed by the first pushing assembly can be smoothly received, further improving the automation efficiency. At the same time, the first protrusion arranged at intervals further enhances the friction fixing effect of the inner tube cake of the firework and the ribbon, so that the inner tube cake of the firework and the ribbon can be kept stable and not fall off during pushing and lifting.

[0083] Preferably, referring to Figure 6 and Figure 7 The clamping assembly 3 further comprises a scraper 314 arranged at the front side of the upper clamping block 311 and the lower clamping block 312.

[0084] One side of the scraper 314 is provided with a second protrusion 314a.

By adding a scraper on the front side of the clamping assembly and arranging protrusions, the surface of the firework inner cylinder cake and its strap can be scraped and limited during the pushing process, so that the firework inner cylinder cake remains regular during clamping and pushing, and tilting or deviation is avoided. More importantly, when the first push head pushes the firework inner cylinder cake into the lifting assembly, the second protrusion can resist the strap, so that the strap is smoothly hung on the first push head, thereby ensuring the reliable hanging of the strap and the smooth performance of the subsequent recycling action. At the same time, the avoiding slot on the edge of the first push head is matched with the protrusion, so that the first push head can smoothly pass through the position of the scraper and the protrusion during reciprocating motion, avoiding interference or jamming.

[0087] Preferably, referring to Figures 8-11 , the lifting assembly 4 comprises: a first side plate 41, a second side plate 42 and a second clamp 43;

[0088] The first side plate 41 is arranged between the clamping assembly 3 and the first side of the second clamp 43, and the bottom is provided with a second cavity 41a matched with the firework inner cylinder cake 6, and the second cavity 41a is provided with a third cavity 41b matched with the second push head 51 above;

[0089] The second side plate 42 is arranged on the second side of the second clamp 43, and the bottom is in abutment with the second clamp 43, and the top is provided with a fourth cavity 42a corresponding to the third cavity 41b;

[0090] The second clamp 43 is arranged between the first side plate 41 and the second side plate 42 in a lifting manner, and the second clamp 43 is provided with a fifth cavity 431 matched with the firework inner cylinder cake 6.

[0091] In this embodiment, when the first pushing assembly pushes the firework inner cylinder cake clamped by the clamping assembly, the strap is hung on the first push head, and the whole firework inner cylinder passes through the second cavity of the first side plate and enters the fifth cavity of the second clamp; the third side plate is in abutment with the second clamp, effectively preventing the firework inner cylinder from being pushed out or displaced, and ensuring lateral stability. Subsequently, the second clamp drives the firework inner cylinder to rise to the third cavity of the first side plate, the second push head of the second pushing assembly passes through the third cavity and cooperates with the second clamp to push the firework inner cylinder out of the fourth cavity row by row, realizing the layer-by-layer feeding of the firework inner cylinder. This design realizes the stable, continuous and precise layer-by-layer feeding of the firework inner cylinder through the multi-cavity guiding, clamping and pushing cooperation, further improves the automation level, safety and reliability of the feeding process, and effectively prevents the firework inner cylinder from tilting, shaking or falling.

[0092] Preferably, referring to Figure 8 and Figure 11The lateral width of the second push head 51 is greater than the maximum lateral width of the fifth cavity 431.

[0094] The upper and lower widths of the push grooves 432 are less than the diameter of the firework inner tube 62, and the interval distance between adjacent push grooves 432 is equal to the diameter of the firework inner tube 62.

[0095] In this embodiment, the lateral width of the second push head is greater than the maximum width of the fifth cavity, and the push grooves sequentially and spacedly provided from bottom to top, which ensures that the second push head can fully cover, uniformly and layer by layer push out the stacked firework inner tubes from top to bottom. At the same time, the upper and lower widths of the push grooves are less than the diameter of the firework inner tube, and the groove interval is equal to the diameter of the firework inner tube, which can effectively limit and guide the firework inner tube to prevent it from tilting, mispositioning or missing pushing, realize the layer by layer, accurate and stable pushing out of the firework inner tube, and improve the continuity, reliability and safety of the feeding.

[0098] The first push driving member 22a, the second push driving member 22b, the mounting plate 23, and the auxiliary plate 24.

[0099] The first push driving member 22a is arranged on one side of the mounting plate 23 and connected with the first push head 21 through the mounting plate 23.

[0100] The auxiliary plate 24 is movably arranged on the first push head 21 and is provided with a sixth cavity 241 matched with the shape of the first push head 21.

[0101] In this embodiment, a collection barrel is added on the conveying assembly for recycling the ribbon, so as to be recycled subsequently. Specifically, the first pushing driving member of the first pushing assembly pushes the firework inner tube cake into the clamping assembly first, and then pushes the firework inner tube to the lifting assembly, and the ribbon is hung on the first push head; the first pushing driving member retreats, drives the first push head to retreat to the initial position, and then moves to the recycling barrel. At this time, the second pushing driving member drives the auxiliary plate to move forward, and the sixth cavity pushes against the first push head to push out the ribbon hung on the first push head, and makes the ribbon fall off and fall into the collection barrel, so as to realize the automatic recycling of the ribbon. Since the whole firework inner tube feeding process and the ribbon recycling process are continuously and automatically completed, the risk of manual operation is avoided, and the safety and automation level of the production process are further improved.

[0102] For example, the first pushing driving member can be a double-stroke air cylinder or a motor lead screw driving mechanism, etc.; in the first state, the first push head is located at the first side of the conveying assembly; in the second state, when the conveying assembly transports the firework inner tube cake to align with the clamping assembly, the pushing driving member drives the first push head to push the firework inner tube cake into the clamping assembly, and the clamping assembly clamps the firework inner tube cake and the ribbon; in the third state, the pushing driving member drives the first push head again to push the firework inner tube into the lifting assembly, and the ribbon is hung on the first push head. For example, the second pushing driving member can be a cylinder, a hydraulic cylinder or a motor driving mechanism.
