Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of fireworks group pot machine forming device and fireworks group pot machine, belong to fireworks manufacturing technical field. BACKGROUND

[0002] The group pot process in fireworks manufacturing process is the key link of fireworks forming, and its core process includes fireworks cylinder arrangement, fire lead assembly, glue curing, multi-layer stacking and bundling reinforcement and other steps. The traditional manual group pot mode has significant defects such as low operation efficiency, poor positioning accuracy, high safety risk, etc., prompting the industry to transform and upgrade to automatic equipment. The modern group pot machine realizes the automatic arrangement and combination of fireworks cylinders through the collaborative operation of the blanking mechanism, the pusher device, the punching and lead insertion module, the glue spraying system and the pressing mechanism.

[0003] In the fireworks production process, the cylinder row that completes the punching process will be assembled into a block-shaped combination in the forming system. After the fireworks are ignited, the internal gunpowder will rapidly burn and produce a large amount of heat and flame. If the cylinder spacing is too small, the high temperature may ignite the gunpowder in the adjacent cylinder, causing chain explosion or uncontrolled combustion. Therefore, in order to ensure the safety of fireworks display, a spacing strip needs to be placed between the cylinder rows. The spacing strip (usually made of flame-retardant material) can block heat transfer, increase the spacing between adjacent cylinder rows, and reduce the risk of accidents. UTILITY MODEL CONTENT

[0004] The utility model aims at the above technical problems, and provides a fireworks group pot machine forming device and fireworks group pot machine that can continuously install spacing strips.

[0005] To achieve the above purpose, the technical scheme adopted by the utility model is:

The spacing strip pushing mechanism includes a frame, a blanking structure arranged on the frame, a pushing structure located below the blanking structure, and a glue coating structure arranged on the front side of the blanking structure. The blanking structure includes two vertically arranged blanking grooves, and the bottom of the blanking groove is provided with a discharge port. The pushing structure includes an installation platform that can reciprocate under the control of a driving member, and the installation platform is provided with a pushing rod corresponding to the position of the discharge port and a receiving member arranged on one side of the pushing rod. The receiving member can reciprocate up and down relative to the installation platform, and the receiving member has a receiving surface inclined towards the feeding direction.

[0007] Thus, when the first group of cylinder arrays enters the forming device station, the spacing strip pushing mechanism is started. The pushing rod pushes the spacing strip in the blanking structure to the upper side of the cylinder array along the horizontal direction under the drive of the driving member; at the same time, the receiving member of the pushing structure moves forward synchronously with the mounting platform, and after reaching the target position, is lifted to a preset height higher than the pushing rod by the lifting mechanism, thereby reserving space for the introduction of the next group of cylinder arrays.

[0008] When the subsequent cylinder array enters the station, the front end thereof is in contact with the inclined receiving surface of the receiving member. Since the receiving surface is inclined upward along the feeding direction, the cylinder array is naturally lifted during the advancing process under the guidance of the inclined surface, thereby avoiding rigid collision with the side wall of the receiving member, and at the same time, smoothly sliding into the upper side of the previous group of cylinder arrays, thereby realizing accurate layering alignment.

[0009] After the introduction of the cylinder array is completed, the receiving member is lowered to the low position, the pushing structure is retreated and reset along the guide rod as a whole, and the pushing rod and the receiving member completely exit the forming area. Subsequently, the pressing mechanism vertically presses downward, thereby compacting and shaping the layered cylinder array and the spacing strip.

[0010] Then, the pushing structure moves forward again, the pushing rod pushes the new spacing strip to the upper side of the compacted cylinder array, and the receiving member is synchronously lifted into the standby state. The above-mentioned actions are periodically repeated until the multi-layer group pot forming of the firework cylinder is completed.

DETAILED DESCRIPTION

[0034] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments. It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict. For the sake of description, if "up", "down", "left", "right" appear in the following text, it only means consistent with the up, down, left and right directions of the drawings themselves, and does not limit the structure.

[0035] As Figure 1As shown, the forming device of the fireworks group pot machine of the embodiment comprises a spacing strip pushing mechanism 1 and a pressing mechanism 3 arranged on a rack 2 and located at the front end of the spacing strip pushing mechanism 1; the spacing strip pushing mechanism 1 comprises a rack body 11, a blanking structure 12 arranged on the rack body 11, a pushing structure 13 located at the lower side of the blanking structure 12, and a gluing structure 9 arranged at the front side of the blanking structure 12.

[0036] As shown in the drawings, Figure 2 the blanking structure 12 comprises two vertically arranged blanking grooves 14, and the bottom of each blanking groove 14 is provided with a discharge port 141; the pushing structure 13 comprises a mounting platform 15 capable of reciprocating under the control of a driving member 4, the mounting platform 15 is provided with a pushing rod 16 corresponding to the position of the discharge port 141 and a receiving member 17 arranged on one side of the pushing rod 16; a limiting plate 161 extending along the length direction of the pushing rod 16 is arranged at the front end of the pushing rod 16; the receiving member 17 can reciprocate up and down relative to the mounting platform 15, and the receiving member 17 has a receiving surface 171 inclined towards the feeding direction.

[0037] As shown in the drawings, Figure 2 , Figure 3 Specifically, the receiving member 17 is inclined upward along the feeding direction of the spacing strip pushing mechanism 1, and the inclination angle is 7.5°-9.5°. This angle range is optimized, which can not only ensure the effective receiving of the spacing strip by the receiving member, but also will not affect the normal pushing of the spacing strip, thereby improving the working efficiency and stability of the device. The receiving member 17 is plate-shaped, and the receiving surface 171 is the upper surface of the receiving member 17.

[0038] The working process of the fireworks group pot machine forming device of the embodiment is as follows:

[0039] 1. Initial pushing stage: when the first group of cylinder rows 115 enter the forming device station, the spacing strip pushing mechanism 1 is started. The pushing rod 16 pushes the spacing strip 116 in the blanking structure 12 to the upper side of the cylinder row 115 along the horizontal direction under the driving of the driving member 4; at the same time, the receiving member 17 of the pushing structure 13 moves forward synchronously with the mounting platform 15, and is lifted to a preset height higher than the pushing rod 16 after reaching the target position, thereby reserving space for the introduction of the next group of cylinder rows 115.

[0040] 2. Continuous feeding and guiding stage: when the subsequent cylinder rows 115 enter the station, the front end thereof is in contact with the inclined receiving surface 171 of the receiving member 17. Since the receiving surface 171 is inclined upward along the feeding direction (7.5°-9.5°), the cylinder rows 115 are naturally lifted under the guidance of the inclined surface during the advancing process, thereby avoiding rigid collision with the sidewall of the receiving member, and at the same time, smoothly sliding into the upper side of the previous group of cylinder rows 115, thereby realizing accurate layering and alignment.

[0041] 3. Reset and Compaction Stage: After the cylinder array 115 is introduced, the receiving component 17 descends to its lowest position, and the entire pushing structure 13 retracts and resets along the guide rod 18. The pushing rod 16 and the receiving component 17 completely exit the forming area. Subsequently, the push plate 32 of the pressing mechanism 3 presses down vertically under the drive of the gear rack, compacting and shaping the stacked cylinder array 115 and the spacer strip 116.

[0042] 4. Cyclic Execution: The pusher structure 13 moves forward again, and the pusher rod 16 pushes the new spacer strip 116 above the compacted tube array. Simultaneously, the receiving part 17 is raised and enters the standby state. The above actions are repeated periodically until the multi-layer assembly of the firework tube is completed.

[0043] like Figure 3 As shown, in this embodiment, the pusher structure 13 is driven by a rack and pinion mechanism. The drive component 4 is a servo motor. A gear 5 is provided at the output end of the drive component 4, and a rack 51 meshing with the gear 5 is provided at the bottom of the mounting platform 15. A guide rod 18 extending along the movement direction of the mounting platform 15 is provided on the frame 11, and a guide block 19 slidably connected to the guide rod 18 is connected to the lower side of the mounting platform 15. When the drive component 4 is working, the drive component 4 converts the circular motion of its output end into the reciprocating linear motion of the mounting platform by rotating forward and backward, thereby enabling the pusher rod 16 and the receiving component 17 to complete the work of pushing and receiving the cylinder. By using a servo motor, the stroke of the pusher rod 16 and the receiving component 17 can be easily controlled to adapt to the forming work of cylinders of different sizes.

[0044] like Figure 2 , Figure 3 As shown, in this embodiment, to facilitate control of the vertical reciprocating movement distance of the receiving component 17, a first mounting component 6 extending along the movement direction of the mounting platform 15 is provided on the upper surface of the mounting platform 15. A second mounting component 7 capable of vertical reciprocating movement is provided on the upper side of the first mounting component 6, and the receiving component 17 is provided at the front end of the second mounting component 7. A drive motor 8 is provided on the upper side of the first mounting component 6, and the second mounting component 7 is rotatably connected to the output end of the drive motor 8. A guide sleeve 81 is also provided on the upper side of the first mounting component 6. The fixed part of the guide sleeve 81 is fixedly connected to the first mounting component 6, and the telescopic part of the guide sleeve 81 is fixedly connected to the second mounting component 7. The drive motor 8 is selected as a servo motor.

[0045] When the driving motor 8 works, the second mounting member 7 will make up-down reciprocating motion along the extension direction of the guide sleeve 81 under the limiting action of the guide sleeve 81 through the forward and reverse rotation of the driving motor 8, so as to drive the up-down reciprocating motion of the receiving member 17, because the output end of the driving motor 8 is rotationally connected with the second mounting member 7. Through the setting of the driving motor 8 and the guide sleeve 81, the motion stroke of the receiving member 17 is facilitated to be controlled, so as to adapt to the cylinder row forming of different sizes and different heights.

[0046] As shown in the drawings, Figure 4 In the embodiment, the pressing mechanism 3 is also improved, the pressing mechanism 3 comprises a fixed member 31 fixedly connected with the rack 2, a push plate 32 capable of moving up and down is arranged on the fixed member 31; a driving motor 33 is arranged on the fixed member 31, a gear 34 is arranged on the output end of the driving motor 33, a rack 35 meshing with the gear 34 is arranged on the upper surface of the push plate 32; a guide element 36 extending upward along the height direction of the rack 2 is arranged on the fixed member 31, and the lower end of the guide element 36 is fixedly connected with the upper surface of the push plate 32. The driving motor 33 is selected as a servo motor.

[0047] Through the gear 34 and the rack 35, the forward and reverse rotation of the driving motor 33 can control the up-down reciprocating motion of the push plate 32. Compared with the traditional air cylinder, the driving motor 33 adopting the servo motor is more convenient to control the stroke size of the push plate 32, and at the same time, the overall volume is reduced, which is convenient for the maintenance and installation of the device as a whole.

[0048] In the embodiment, through the servo motor, the gear and rack transmission and the guide structure, such as the cooperation of the driving member 4, the gear 5 and the rack 51, the cooperation of the driving motor 33, the gear 34 and the rack 35, and the cooperation of the guide element 36, the motion of each component is accurately controlled, the accuracy of the interval strip pushing and the pressing is ensured, and the quality of the firework group pot is improved.

[0049] As shown in the drawings, Figure 5 Based on the same inventive concept, the embodiment further provides a group pot forming machine, which comprises a main frame body 101, an inlet mechanism 111, a punching and inserting mechanism 112, a forming mechanism 113 and an outlet mechanism 114 are sequentially arranged on the main frame body 101 along the material moving direction, and the forming mechanism 113 comprises the firework group pot forming device as described above.

[0050] The above-mentioned embodiments should be understood as being only for more clearly describing the present application, and should not be used to limit the scope of the present application, and after reading the present application, various equivalent modifications of the present application by those skilled in the art all fall within the scope defined by the claims attached herein.
