DETAILED DESCRIPTION

[0035] The following are specific embodiments of the present application and further describe the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help a comprehensive understanding of the embodiments of the present application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope of protection of the present application. In addition, in order to be clear and concise, the description of known functions and structures is omitted.

[0036] It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0037] The present application provides a fireworks inner tube filling and discharging device for pushing the fireworks inner tube in the hopper out for filling. In the existing fireworks inner tube filling equipment, the fireworks inner tube falling from the hopper is pushed out horizontally or at an inclined angle by the pushing mechanism, so that a turnover mechanism needs to be provided to turn the receiving template or the fireworks tube to the corresponding angle to receive the hopper pushed out by the pushing mechanism, which is relatively complex in action and structure. Therefore, the present application provides a fireworks inner tube filling and discharging device which is more simplified in structure and action, and the operation of the equipment is more reliable. The specific description is as follows in conjunction with the drawings.

[0038] Reference Figures 1-3 The fireworks inner tube filling and discharging device includes a hopper 10, a plurality of discharging chutes 20, a plurality of discharging passages 30, and a pushing mechanism 40. The hopper 10 is provided with a fireworks inner tube chute 11. The plurality of discharging chutes 20 extend in the same direction and are arranged transversely below the chute 11. The plurality of discharging passages 30 are located between the chute 11 and the plurality of discharging chutes 20; the plurality of discharging passages 30 are aligned one by one with the plurality of discharging chutes 20 for guiding the fireworks inner tubes in the chute 11 into the plurality of discharging chutes 20 one by one. The pushing mechanism 40 is used to push the fireworks inner tubes on the plurality of discharging chutes 20 forward. Along the pushing direction of the fireworks inner tube, the discharging chute 20 is bent downward in front of the hopper 10 to guide the fireworks inner tube to output downward.

[0039] A row of discharging channels 30 is arranged below the chute 11, and a row of discharging slides 20 is arranged below the discharging channels 30. When the fireworks inner tube filling and discharging device is in operation, the pushing mechanism 40 pushes the fireworks inner tube on the discharging slide 20 forward. As the fireworks inner tube in the discharging slide 20 is pushed out, the fireworks inner tube in the discharging channel 30 falls downward into the discharging slide 20; at the same time, after the discharging channel 30 discharges, the chute 11 above replenishes the fireworks inner tube to the discharging channel 30. Therefore, as the pushing mechanism 40 continuously pushes the fireworks inner tube on the discharging slide 20 forward, the fireworks inner tube in the chute 11 will continuously fall into the discharging slide 20 through the discharging channel 30.

[0040] In the embodiment of the present application, the pushing mechanism 40 includes a pushing member 41 and a first driving element 42. The pushing member 41 is provided with a plurality of pushing rods 411, and the plurality of pushing rods 411 correspond to the plurality of discharging slides 20 one by one. The first driving element 42 is used to drive the pushing member 41 to act, so that the plurality of pushing rods 411 respectively push the fireworks inner tube on the plurality of discharging slides 20 forward. When the first driving element 42 drives the pushing member 41 to move forward, the plurality of pushing rods 411 on the pushing member 41 simultaneously push the fireworks inner tube in the plurality of discharging slides 20 forward. Here, the first driving element 42 can be a pneumatic cylinder.

[0041] In the embodiment of the present application, along the pushing direction of the fireworks inner tube, the discharging slide 20 is bent downward in front of the hopper 10 to guide the fireworks inner tube to output downward. Therefore, the fireworks inner tube filling and discharging device provided by the embodiment of the present application guides the fireworks inner tube to output downward by arranging the bent discharging slide, without arranging a turnover mechanism, which simplifies the structure and action, and makes the operation of the equipment more reliable.

[0042] Reference Figure 4The fireworks inner tube filling and discharging device further comprises a material blocking mechanism 50 arranged at the discharging end of the plurality of discharging slides 20, which comprises a material blocking plate 51 and a second driving element 52. The material blocking plate 51 is provided with a plurality of material passing holes 511 through which the fireworks inner tube passes, and the plurality of material passing holes 511 correspond to the plurality of discharging slides 20 one by one. The second driving element 52 is used to drive the material blocking plate 51 to act, so that the plurality of material passing holes 511 on the material blocking plate 51 are aligned with or staggered with the plurality of discharging slides 20. In operation, the material pushing mechanism 40 pushes the fireworks inner tube on the discharging slide 20 forward, and the fireworks inner tube in the discharging slide 20 moves along the discharging slide 20 to the discharging end. When discharging is needed, the second driving element 52 drives the material blocking plate 51 to act so that the plurality of material passing holes 511 on the material blocking plate 51 are aligned with the plurality of discharging slides 20, at this time, the fireworks inner tube in the discharging slide 20 can be discharged and output through the material passing holes 511 on the material blocking plate 51. When discharging is not needed, the second driving element 52 drives the material blocking plate 51 to act so that the plurality of material passing holes 511 on the material blocking plate 51 are staggered with the plurality of discharging slides 20, at this time, the fireworks inner tube in the discharging slide 20 is blocked by the material blocking plate 51 and cannot be discharged.

[0043] Reference Figure 2 The fireworks inner tube filling and discharging device further comprises a downward pushing mechanism 60, which comprises a downward pushing piece 61 and a third driving element 62. The downward pushing piece 61 is located above the discharging end of the plurality of discharging slides 20 and is provided with a plurality of downward pushing rods 611 corresponding to the plurality of discharging slides 20. The third driving element 62 is used to drive the downward pushing piece 61 to act, so that the plurality of downward pushing rods 611 respectively pass through the discharging end of the plurality of discharging slides 20 and enter the filling hole. Specifically, when the fireworks inner tube in the discharging slide 20 is discharged, the third driving element 62 can drive the downward pushing piece 61 to act so that the plurality of downward pushing rods 611 respectively pass through the discharging end of the plurality of discharging slides 20 and enter the filling hole, thereby ensuring that the fireworks inner tube enters the filling hole and avoiding jamming. After one downward pushing action, the third driving element 62 can drive the downward pushing piece 61 to move upward to the initial position.

[0044] Reference Figure 4 and Figure 5, multiple discharge slides 20 are separated by multiple long strip-shaped partitions 21 which are spaced apart, and a discharge slide 20 is formed between each adjacent two partitions 21; a support 22 which extends in the same direction as the partition 21 is arranged between each adjacent two partitions 21, and the support 22 constitutes a bottom structure of the discharge slide 20 to support the inner tube in the discharge slide 20. Further, the support 22 is a long strip-shaped plate structure; multiple long strip-shaped partitions 21 and supports 22 are connected together through a transverse connecting rod 23. Specifically, the long strip-shaped partitions 21 are transversely spaced apart to form an open discharge slide 20, and when the inner tube W of the firework is placed between the two partitions 21, the bottom support 22 can support it. Referring to Figure 2 , the third driving element 62 can drive the push rod 611 to be inserted downward into the discharge slide 20.

[0045] A vertical baffle 24 is arranged in front of the discharge slide 20, and the vertical baffle 24 abuts against the long strip-shaped partition 21 to seal the discharge slide 20 from the front. In this structure, the vertical baffle 24 seals the discharge slide 20 from the front to prevent the inner tube of the firework from sliding out of the discharge slide 20.

[0046] Referring to Figure 6 , in an embodiment of the present application, along the pushing direction of the inner tube of the firework, the discharge slide 20 sequentially includes: a first linear slide 20a, a curved slide 20b, and a second linear slide 20c; wherein the first linear slide 20a has an inclination angle and is inclined forward along the pushing direction; the second linear slide 20c extends vertically downward; and the curved slide 20b is used to bend the first linear slide 20a to the second linear slide 20c. In Figure 6 , the hopper 10 is located above the first linear slide 20a, and the pushing mechanism 40 is located on one side of the first linear slide 20a; when the pushing mechanism 40 pushes the inner tube of the firework in the discharge slide 20 forward, the inner tube of the firework sequentially passes through the first linear slide 20a, the curved slide 20b, and the second linear slide 20c to be output, and on the curved slide 20b, the inner tube of the firework is converted from the sliding direction of the first linear slide 20a to the vertically downward direction of the second linear slide 20c. Here, the first linear slide 20a has an inclination angle and is inclined forward along the pushing direction, so that the bending amplitude of the curved slide 20b is smaller, and the inner tube of the firework is easier to pass through.

[0047] In an embodiment of the present application, the discharge chute 20 comprises, in sequence along the pushing direction of the inner tube of the firework, a first linear chute 20a, a curved chute 20b, and a second linear chute 20c; the first linear chute 20a extends horizontally; the second linear chute 20c extends vertically downward; the curved chute 20b is used to bend the first linear chute 20a to the second linear chute 20c. When the pushing mechanism 40 pushes the inner tube of the firework in the discharge chute 20 forward, the inner tube of the firework passes through the first linear chute 20a, the curved chute 20b, and the second linear chute 20c in sequence and is output, and on the curved chute 20b, the inner tube of the firework is switched from the sliding direction of the first linear chute 20a to the vertically downward direction of the second linear chute 20c.

[0048] The present application also provides a firework production line, which has the inner tube filling and discharging device provided in the previous part. The inner tube of the firework discharged by the inner tube filling and discharging device can be directly filled into the firework tube, or can be first filled into the material holes of the transfer template and then transferred and filled into the firework tube by the transfer template.

[0049] The inner tube filling and discharging device comprises a hopper, a plurality of discharge chutes, a plurality of material falling channels, and a pushing mechanism. The hopper is provided with a material groove for the inner tube of the firework. The plurality of discharge chutes extend in the same direction and are arranged transversely below the material groove. The plurality of material falling channels are located between the material groove and the plurality of discharge chutes; the plurality of material falling channels are aligned with the plurality of discharge chutes one by one, so as to correspondingly guide the inner tube of the firework in the material groove into the plurality of discharge chutes. The pushing mechanism is used to push the inner tube of the firework on the plurality of discharge chutes forward. Along the pushing direction of the inner tube of the firework, the discharge chute is bent downward in front of the hopper to guide the inner tube of the firework to output downward. In the above technical solution, the discharge chute is bent to guide the inner tube of the firework to output downward, and the turnover mechanism is omitted, so that the structure and action are simplified, and the operation of the equipment is more reliable.

[0050] It should be understood that the firework production line includes a plurality of firework production steps, such as the filling of military gunpowder, the filling of paper barba, the filling of the inner tube, and a plurality of detection steps, which involve a plurality of devices.
