[0030] In order to more clearly illustrate the technical solutions in the utility model or the prior art, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] refer to Figure 1-Figure 9 A mold shifting device for a fireworks inner tube filling machine includes a first guide plate 10, a second guide plate 11, a third guide plate 12, a fourth guide plate 13 of a guide assembly, a filling template 20, a mold shifting assembly 30, and a whole mold pressing assembly 40. The filling template 20 is provided with a plurality of filling holes 21 corresponding to the fireworks outer tube 60 for filling the fireworks inner tube 50. The number and arrangement shape of the filling holes 21 on the filling template 20 corresponding to different fireworks products are different.

[0032] The mold shifting assembly 30 includes a movable member 31 and a first driving member 32 . The filling template 20 is mounted on the movable member 31 . The mold shifting assembly 30 is located below the first guide plate 10 .

[0033] refer to Figure 1-Figure 7 The first guide plate 10 of the mold shifting device is installed at the end of the unloading device 70 of the firework inner tube filling machine. The position of the first guide plate 10 corresponds vertically to the end of the unloading device 70. When the firework inner tube 50 is pushed forward by the unloading device 70, it hits the first guide plate 10 and falls down. The first guide plate 10 is vertically provided with an inner tube pressing member lower pressing plate 14. The end surface of the inner tube pressing member lower pressing plate 14 is provided with a plurality of partitions 15, and there is a protrusion between each two adjacent partitions 15. The second driving member cylinder 16 is correspondingly provided on both sides of the first guide plate 10 vertically; the first guide plate 10 moves downward under the action of the second driving member cylinder 16.

[0034] refer to Figure 3 , Figure 5 , Figure 6 and Figure 7The second guide plate 11, the third guide plate 12, and the fourth guide plate 13 are installed on the vertically opposite surface of the first guide plate 10. There are multiple second guide plates 11 and third guide plates 12. The number of second guide plates 11 and the spacing distance between each second guide plate 11 are set according to the setting of the upper limit groove on the limit plate of the fireworks inner tube filling device. The third guide plate 12 is set between every two second guide plates 11. The second guide plate 11 and the third guide plate 12 are both bent in shape. The setting of the bent shape is to facilitate the fireworks inner tube 50 to lean against the third guide plate 12 during the free fall process and fall vertically downward in the area framed by the two adjacent second guide plates 11, just like the fireworks inner tube falls on a slide. The back of each second guide plate 11 and each third guide plate 12 is connected to the fourth guide plate 13. The second guide plate 11 and the third guide plate 12 are connected to the fourth guide plate 13 to form an integral part installed below the end of the unloading device of the fireworks inner tube filling machine. In order to better fix the second guide plate 11 and the third guide plate 12, the fourth guide plate 13 is also set to a bent shape, and the upper and lower ends fix the second guide plate 11 and the third guide plate 12. As another embodiment, the fourth guide plate 13 can be set as a horizontal plate or two upper and lower horizontal plates. The connection between the second guide plate 11, the third guide plate 12 and the fourth guide plate 13 can be a fixed connection, or it can be a movable connection, a slot connection or other connection methods. In the actual production process, gaps should be left between the guide plates to facilitate the collection and cleaning of dust and debris.

[0035] As another implementation, the second guide plate 11 and the third guide plate 12 may also be installed on the first guide plate 10 .

[0036] As another embodiment, the third guide plate 12 can be provided separately, and the technical effect achieved by the arrangement method and structure thereof is to allow the firework inner tube 50 to smoothly slide into the filling hole 21 of the filling template 20 with its back against the third guide plate.

[0037] Because there is dust and ash in the production process of fireworks and the fireworks inner tube 50 may be stuck and cannot fall smoothly during the falling process, the first guide plate 10 moves downward under the action of the second driving member cylinder 16, and the inner tube pressing member lower pressing plate 14 moves downward accordingly. The protrusion between the two partition grooves 15 on the end surface of the inner tube pressing member lower pressing plate 14 pushes the fireworks inner tube 50 downward vertically, and the fireworks inner tube 50 is pressed down by the inner tube pressing member lower pressing plate 14 in the channel defined by the first guide plate 10, the two adjacent second guide plates 11 and the third guide plate 12, and falls freely into the filling hole 21 of the filling template 20.

[0038] As another embodiment, the lower pressing plate 14 of the inner tube pressing member may not be installed on the first guide plate 10. The lower pressing plate 14 is independently connected to the driving member, and under the action of the driving member, the firework inner tube 50 is pushed to fall freely into the filling hole 21 of the filling template 20.

[0039] refer to Fig. 9 The mold shifting assembly 30 includes a movable member 31 and a first driving member 32. The movable member 31 includes two corresponding support plates 310 and two moving shafts 311, the two support plates 310 and the two moving shafts 311 are respectively fixedly connected, and the moving shafts 311 are fixed on the frame through four first bearing seats 312. The first driving member 32 includes a driving source servo motor 320, a coupling 321, and a moving screw 322. The servo motor 320 and the moving screw rod 322 are respectively fixed on the frame through multiple second bearing seats 324. The servo motor 320 and the moving screw rod 322 are connected through a coupling 321. One end of the moving screw rod 322 is connected to the transmission plate 323. The two ends of the transmission plate 323 are respectively connected to the two support plates 310. The two sides of the filling template 20 are respectively connected to the bottom of the two support plates 310. The support plates 310, the moving shaft 311 and the filling template 20 together form a moving frame, which can move back and forth with the moving shaft 311 within the distance limited by the corresponding first bearing seats 312.

[0040] The four top corners of the bottom of the filling template 20 are movably mounted on the fixed plate 22 through four support plates 24, and a plurality of through holes 25 corresponding to the filling holes of the filling template 20 are arranged on the fixed plate 22; the fourth driving member cylinder 23 and the fifth driving member yaw cylinder (not shown in the figure) are installed on the fixed plate 22, and a horizontal plate (not shown in the figure) is installed at the bottom of the filling template 20, and the piston rods of the fourth driving member cylinder 23 and the fifth driving member yaw cylinder are connected to the horizontal plate of the filling template 20 to drive the filling template 20 to move, and the fifth driving member yaw cylinder is installed on the fourth driving member cylinder 23.

[0041] When the servo motor 320 is started, the movable screw 322 is driven to rotate through the coupling 321, and the movable shaft 311 moves toward the movable screw 322 within the straight-line distance defined by the corresponding first bearing seats 312. The filling template 20 moves back and forth in a straight line along with the support plate 310 driven by the two movable shafts 311 through the forward and reverse rotation of the servo motor 320.

[0042] During the process of filling the inner tube with the filling template 20, the through hole 25 on the fixed plate 22 is misaligned with the filling hole 21 of the filling template 20. This misalignment can retain the inner tube that has been filled on the filling template 20 in the filling hole 21 without falling. When all the inner tubes on the filling template 20 are filled and moved to the outer tube filling position, the fourth driving member cylinder 23 is a push-die cylinder, and its function is to push the filling template 20 to move. The through hole 25 on the fixed plate 22 coincides with the filling hole 21 of the filling template 20, and the firework inner tube 50 is filled into the firework outer tube 60 through the through hole 25 on the fixed plate 22.

[0043] refer to Fig.10 and Fig.11 The fireworks outer tube 60 is designed in various arrangements according to different fireworks products. Fig.10 It is the common arrangement of the fireworks outer tube 60. Fig.11 The fireworks outer tube 60 is arranged in a staggered manner. If the outer tube 60 is arranged in a staggered manner, the corresponding inner tube 50 should also be set to the staggered arrangement shape so that it can be filled into the outer tube 60. The function of the fifth driving member, the yaw cylinder, is to drive the filling template 20 to shift during the filling process of the inner tube 50, so that the fireworks inner tube 50 filled on the filling template 20 is filled in the filling hole 21 in a staggered arrangement shape.

[0044] refer to Figure 8 The whole mold pressing assembly 40 includes a lower pressing plate 410 and a third driving member cylinder 411. The lower pressing plate 410 is provided with a plurality of cylinder shafts 415 corresponding to the filling holes 21 of the filling template 20. The four top corners of the pressing plate 410 are respectively provided with guide shafts 412. The guide shafts 412 are fixed to the horizontal plates 414 on the left and right sides through linear bearings 413. The horizontal plates 414 are fixed to the frame. The lower pressing plate 410 moves up and down along the guide shafts 412 under the action of the third driving member cylinder 411. When the filling template 20 moves to the fireworks outer tube filling position, the whole mold pressing assembly 40 is started, and the third driving member cylinder 411 pushes the lower pressing plate 410 to move downward. The cylinder shaft 415 of the lower pressing plate 410 presses against the fireworks inner tube 50 on the filling template 20 to fill into the fireworks outer tube 60.

[0045] The firework inner tube filling machine is started, and the servo motor 320 drives the movable screw 322 to rotate through the coupling 321. The filling template 20 moves to the end of the firework inner tube filling machine unloading device 70 along with the support plate 310 through the two movable shafts 311. The firework inner tube 50 is pushed toward the first guide plate 10 at the end of the inner tube filling machine unloading device. The first guide plate 10 blocks the forward advancement of the firework inner tube 50. After being blocked by the first guide plate 10, the firework inner tube 50 freely falls downward against the third guide plate 12. The second driving member cylinder 16 is started to drive the first guide plate 10 to move downward, and the lower pressure plate 14 moves downward. The protrusion on the lower pressure plate 14 pushes the firework inner tube 50 to fall vertically downward. The firework inner tube 50 freely falls into the filling hole 21 of the filling template 20 in the channel defined by the first guide plate 10, the two adjacent second guide plates 11 and the third guide plate 12.

[0046] The unloading device 70 of the fireworks inner tube filling machine pushes the fireworks inner tubes 50 row by row, and the filling template 20 also fills the fireworks inner tubes 50 row by row accordingly. The movable parts 31 complete the filling of each row of fireworks inner tubes one by one. After the filling template 20 completes the inner tube filling according to the arrangement design of the fireworks products, the filling template 20 moves to the position of the fireworks outer tube along with the movable parts 31, the whole mold pressing assembly 40 is started, and the third driving component cylinder 411 pushes the lower pressing plate 410 to move downward, and the cylinder shaft 415 of the lower pressing plate 410 presses against the fireworks inner tubes 50 on the filling template 20 to fill them into the fireworks outer tube 60, completing the filling of the fireworks inner tubes.
