[0024] In a further embodiment, the medicine stick has a hollow structure at the head, and the outer diameter of the hand-held stick is slightly smaller than the inner hole diameter of the medicine stick.

[0025] The end of the hand-held stick near the medicine stick after glue applying coincides with the medicine stick under the pushing of the ejector rod, the setting that the outer diameter of the hand-held stick is slightly smaller than the inner hole diameter of the medicine stick makes the coinciding and inserting work more smoothly, and the completeness of the medicine stick structure is not damaged.

[0048] Figure 2a -b shows a structure schematic view of an automatic conveying material preparation mechanism of a two-section handheld firework assembling device of the present application, Figure 2c For the specific structure schematic view of the aligning and assembling mechanism of a two-section handheld firework assembling device of the present application, as shown in Figure 2a As shown in c, the conveying component 22 includes a ratchet wheel set 221 and a groove wheel set 222, the ratchet wheel set 221 is fixedly arranged below the material feeding and discharging mechanism, and multiple groove wheel sets 222 are sequentially connected and fixedly arranged below the ratchet wheel set 221.

[0049] The conveying component 22 of the automatic conveying material preparation mechanism 2 includes a ratchet wheel set 221 and a groove wheel set 222. The ratchet wheel mechanism has the advantages of simple structure, relatively stable and intermittent indexing, and high mechanical efficiency. It is used to receive handheld rods and charge rods from the material feeding and discharging mechanism. Compared with the ratchet wheel mechanism, the groove wheel mechanism moves more smoothly when it is engaged and disengaged. Multiple groove wheel sets 222 are sequentially connected to smoothly transport and convey the handheld rods 100 and the charge rods 200. The circumferences of the ratchet wheel and the groove wheel are evenly distributed with a plurality of grooves. When the material is received and transported, the handheld rods 100 and the charge rods 200 are respectively dropped into the grooves of the ratchet wheel and the groove wheel. The ratchet wheel set 221 and the groove wheel set 222 rotate under the driving of the shaft 21. By controlling the speed of the material discharging and the automatic conveying material preparation mechanism 2, multiple handheld rods 100 and charge rods 200 can be continuously stored.

[0050] In further embodiments, the ratchet wheel set 221 includes four ratchet wheels, and multiple groove wheel sets 222 respectively include four groove wheels. Multiple groove wheel sets are respectively a first groove wheel set 2221, a second groove wheel set 2222, and a third groove wheel set 2223.

[0052] In specific embodiments, the automatic conveying material preparation mechanism 2 further includes multiple gears 23, multiple gears 23 are respectively fixedly arranged at the shaft ends of multiple shafts 21, and multiple gears 23 are sequentially engaged.

[0053] The shafts 21 and the gears 23 correspond in number to the transmission components 22, and are driven by the meshing between the gears 23, so that the shafts 21 rotate in opposite directions, and the shafts 21 rotate synchronously, and the transmission components 22 on the shafts 21 rotate, so that the handheld sticks and the medicine sticks are transmitted forward.

[0054] In a specific embodiment, the pawl set 221 and the ratchet set 222 are respectively provided with a baffle 25 for limiting the movement of the handheld sticks and the medicine sticks.

[0055] The baffle 25 limits the movement of the handheld sticks 100 and the medicine sticks 200 on the ratchet set 221 and the ratchet set 222 to rotate around the shaft in a circumferential range, so as to improve the transmission efficiency.

[0056] In a further embodiment, the baffle 25 is fixed to the rack 5 by a pressing plate 26.

[0057] In a specific embodiment, the alignment assembly mechanism 4 comprises a cam mechanism 41 and a jack 42, the cam mechanism 41 is connected with the jack 42, and the position of the jack 42 corresponds to the wheel groove on the ratchet set 2223.

[0058] In a further embodiment, the cam mechanism 41 comprises two cams 411 and 412 with opposite convex and concave directions, and the protruding part of the jack 42 is fixedly arranged in the channel formed between the cams 411 and 412.

[0060] In a further embodiment, the jack 42 is provided at the head and tail with a limiting slot (not shown in the drawings).

[0061] The limiting slot limits the position of the jack 42 to rotate around the shaft and repeatedly extend and contract along the shaft, so that the alignment assembly mechanism 4 has higher assembly efficiency for the medicine sticks and the handheld sticks.

[0062] In a further embodiment, the medicine stick 200 has a hollow head structure, and the outer diameter of the handheld stick 100 is slightly smaller than the inner diameter of the hole of the medicine stick 200.

[0063] After the adhesive is applied, the end of the handheld stick 100 near the medicine stick is pushed by the top rod 42 to overlap and insert with the medicine stick 200. The setting that the outer diameter of the handheld stick 100 is slightly smaller than the inner diameter of the medicine stick 200 makes the insertion work smoother and does not damage the integrity of the structure of the medicine stick 200. With the help of the adhesive, a stable connection between the medicine stick 200 and the handheld stick 100 is achieved.

Figure 2a As shown in the figure, the two can overlap and connect to realize the forward transport of the hand-held stick and the medicine stick. On the other hand, the first belt 7 drives the first pulley 8 connected to the feeding and unloading mechanism 1 to rotate, which provides a power source for the one-to-one automatic feeding of the feeding and unloading mechanism 1. At the same time, it ensures that the unloading rate and the conveying rate are proportional, and ensures the orderly progress of the conveying work.
