DETAILED DESCRIPTION

[0033] The following is the specific embodiment of the present application and in conjunction with the accompanying drawings, the technical scheme of the present application is further described, but the present application is not limited to these embodiments. In the following description, specific details such as specific configuration and assembly are provided only to help fully understand the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, for clarity and brevity, the description of known functions and structures has been omitted.

[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other.

[0035] refer to Figure 1-Figure 4 The fireworks inner tube discharging device 100 includes a hopper 10, a plurality of discharging chutes 20, and a first pushing assembly 30. The hopper 10 is provided with a trough 11 for fireworks inner tubes. The plurality of discharging chutes 20 extend in the same direction and are arranged at the bottom of the trough 11. The first pushing assembly 30 includes a pushing rack 31, a first driving source 32, a plurality of pushing pieces 33, and a plurality of elastic elements 34; the first driving source 32 is used to drive the pushing rack 31 to move, the plurality of pushing pieces 33 correspond to the plurality of discharging chutes 20 one by one, and the plurality of elastic elements 34 correspond to the plurality of pushing pieces 33 one by one; as the first driving source 32 drives the pushing rack 31 to move, the pushing rack 31 can push the plurality of pushing pieces 33 corresponding to the plurality of discharging chutes 20 through the plurality of elastic elements 34 to push out the inner tubes on all the discharging chutes 20.

[0036] When the fireworks inner tube discharging device 100 is working, the inner tube material needs to be loaded into the material trough 11. The inner tube in the material trough 11 falls from its bottom to the discharging chute 20, and the material trough 11 drops the material once each time the first pushing assembly 30 pushes.

[0037] Specifically, the first pusher assembly 30 includes a pusher frame 31, a first driving source 32, a plurality of pushers 33, and a plurality of elastic elements 34. The first driving source 32 can be specifically configured as a cylinder; as the first driving source 32 drives the pusher frame 31 to move forward, under the action of the elastic element 34, the pusher 33 also moves forward to push the inner cylinder in each discharge chute 20. Figure 3 As shown, multiple pushers 33 correspond to multiple discharge chutes 20 one by one, and multiple elastic elements 34 correspond to multiple pushers 33 one by one. In the process of pushing the inner cylinder, when the inner cylinder in any discharge chute 20 is blocked, the corresponding pusher 33 will compress the elastic element 34 backward, and the rigid impact is avoided through the elastic deformation of the elastic element. Figure 3 As shown, in a specific technical solution, the elastic element 34 is a spring, which is sleeved on the outer circumference of the pushing member 33.

[0038] In one embodiment of the present application, the firework inner tube discharging device 100 further includes a sensor 40, which can sense that the pusher 33 has retreated to a predetermined position relative to the pusher frame 31. Specifically, during the pushing process, when the pusher 33 is blocked, the pusher 33 will retreat a certain distance relative to the pusher frame 31 to form an elastic retreat. Here, by setting a sensor 40 to sense the pusher 33 at a predetermined position, the machine can be stopped in time for processing to avoid further losses. Figure 1-Figure 3 As shown, the sensor 40 is arranged on the pushing rack 31, and senses the position of the pushing member 33 based on the pushing rack 31.

[0039] Continue to refer Figure 1-Figure 3 The pusher frame 31 includes a first side plate 311 and a second side plate 312, and the first side plate 311 and the second side plate 312 are fixed together, and the first side plate 311 is located on the side close to the hopper 10. The pusher 33 passes through the openings on the first side plate 311 and the second side plate 312; a limiting sleeve 331 is provided on the pusher 33, and the limiting sleeve 331 is arranged on the side of the first side plate 311 close to the second side plate 312, and the elastic element 34 is limited between the limiting sleeve 331 and the second side plate 312; when the pusher frame 31 moves forward, the second side plate 312 acts on the limiting sleeve 331 through the elastic element 34 to push the pusher 33 forward; when the pusher frame 31 moves backward, the first side plate 311 presses against the limiting sleeve 331 to push the pusher 33 backward.

[0040] Specifically, the pusher frame 31 includes a first side plate 311 and a second side plate 312, wherein the first side plate 311 is located in front of the second side plate 312 and is closer to the hopper 10. When the first driving source 32 drives the pusher frame 31 to move forward, the second side plate 312 moves forward, and the second side plate 312 presses forward against the elastic element 34 so that the elastic element 34 pushes the limiting sleeve 331 forward, thereby pushing the pusher 33 forward to push the inner cylinder on the discharge slide 20. When the first driving source 32 drives the pusher frame 31 to retreat, the first side plate 311 presses backward against the limiting sleeve 331, thereby driving the pusher 33 to retreat.

[0041] Furthermore, the first driving source 32 is a cylinder, whose cylinder body is installed between the first side plate 311 and the second side plate 312, and whose piston rod is fixed to a fixing frame 50. When extending and retracting, the first side plate 311 and the second side plate 312 move together with the cylinder body. Figure 3 As shown, the cylinder body is located between the first side plate 311 and the second side plate 312, and overlaps with the pusher 33 in the front-to-back direction, so the structure is more compact.

[0042] The above-mentioned fireworks inner tube discharging device is used to reciprocately push out the fireworks inner tube. The pushing rack pushes multiple pushing pieces corresponding to each other through multiple elastic elements. Since elastic elements are arranged between the pushing pieces and the pushing rack, elastic buffering can be provided to avoid rigid impact.

[0043] refer to Figure 5 and Figure 6 The embodiment of the present application also provides a firework inner tube discharging device, which includes the firework inner tube discharging device 100 provided in the previous part, a fixed frame 50, a movable frame 60, a second driving element 70, and a second pushing assembly 80.

[0044] Specifically, a plurality of fixed slideways 51 are provided on the fixed frame 50; a plurality of movable slideways 61 are provided on the movable frame 60; the plurality of movable slideways 61 on the movable frame 60 correspond one-to-one with the plurality of fixed slideways 51 on the fixed frame 50, and the plurality of movable slideways 61 on the movable frame 60 correspond one-to-one with the plurality of discharge slideways 20 of the firework inner tube discharge device 100. The second driving element 70 can drive the movable frame 60 to move between a first position and a second position; when the movable frame 60 is in the first position, the plurality of movable slideways 61 on the movable frame 60 are aligned with the plurality of discharge slideways 20 of the firework inner tube discharge device 100 to receive the inner tube pushed out from the plurality of discharge slideways 20; when the movable frame 60 is in the second position, the plurality of movable slideways 61 on the movable frame 60 are aligned with the plurality of fixed slideways 51 on the fixed frame 50. The second pushing assembly 80 is used to push the inner cylinders on the multiple movable slides 61 into the multiple fixed slides 51 and continue to push them forward along the multiple fixed slides 51 when the multiple movable slides 61 on the movable frame 60 are aligned with the multiple fixed slides 51 on the fixed frame 50.

[0045] Driven by the second driving element 70, the moving frame 60 moves between the first position and the second position, and is used to transfer the inner cylinder pushed out by the fireworks inner cylinder discharging device 100 to the multiple fixed slideways 51 on the fixed frame 50. When the second driving element 70 drives the moving frame 60 to move to the first position, the multiple moving slideways 61 on the moving frame 60 are aligned with the multiple discharging slideways 20 of the fireworks inner cylinder discharging device 100. At this time, the first pushing assembly 30 continuously pushes the inner cylinder on the discharging slideway 20 to the moving slideway 61 of the moving frame 60. After multiple times of pushing, multiple rows of inner cylinders can be formed on the moving slideway 61 of the moving frame 60. As the second driving element 70 drives the moving frame 60 to the second position, the multiple moving slides 61 on the moving frame 60 are aligned with the multiple fixed slides 51 on the fixed frame 50. At this time, the second pushing assembly 80 can push the multiple rows of inner cylinders on the moving slides 61 of the moving frame 60 into the fixed slides 51 and continue to push them forward along the multiple fixed slides 51 for the next step of loading. The second pushing assembly 80 is similar to the first pushing assembly 30, including a pushing structure and a driving source. Under the drive of the driving source, the pushing structure pushes the inner cylinder in the slide.

[0046] Furthermore, the fireworks inner tube discharging device includes a fireworks inner tube discharging device 100, a fixed frame 50, a movable frame 60, a second driving element 70, and a second pushing assembly 80. It should be understood that the fireworks inner tube discharging device 100 is used to push out the inner tube in the hopper, and the second pushing assembly 80 is used to push out the inner tube on the fixed frame 50 to the inner tube transfer mechanism 90 for the next step of loading. The movable frame 60 is arranged between the fireworks inner tube discharging device 100 and the fixed frame 50 to transfer the inner tube, so that the discharging of the fireworks inner tube discharging device 100 and the loading and discharging on the fixed frame 50 can be separated, and the two can be carried out simultaneously, which is more efficient. In addition, the fireworks inner tube discharging device 100 can push out multiple rows of inner tubes at a time, thereby obtaining higher efficiency.

[0047] In one embodiment of the present application, the fireworks inner tube discharging device 100 has a plurality of fireworks inner tube discharging devices 100 and a plurality of movable racks 60 corresponding to each of the plurality of fireworks inner tube discharging devices 100. The plurality of fireworks inner tube discharging devices 100 and the plurality of movable racks 60 work together to alternately transfer the inner tubes to the fixed rack 50, thereby reducing the waiting time of the second pushing assembly 80 and improving the overall efficiency. In addition, for different fireworks inner tube discharging devices 100, inner tubes of different types and specifications can be placed in their hoppers, which is more flexible to use.

[0048] like Figure 5 As shown, a firework inner tube discharging device 100 and a mobile frame 60 are arranged on both sides of the fixed frame 50, and the inner tubes pushed out by the firework inner tube discharging device 100 are transferred to the middle fixed frame 50 through the mobile frame 60 on the same side. The hoppers in the firework inner tube discharging devices 100 on both sides can hold inner tubes of different types and specifications.

[0049] In one embodiment of the present application, for one or more mobile racks 60, a fireworks inner tube discharging device 100 is arranged at both ends of the mobile slideway 61. When the mobile rack 60 is in the first position, the multiple mobile slideways 61 thereon are aligned with the multiple discharging slideways 20 of the fireworks inner tube discharging device 100 at both ends. Therefore, when the mobile rack 60 is in the first position, the fireworks inner tube discharging devices 100 at both ends can push the inner tube to the middle mobile rack 60, thereby improving efficiency.

[0050] In one embodiment of the present application, the discharge chute 20, the fixed chute 51, and the movable chute 61 are all composed of a plurality of rod-shaped bodies 21 extending in the same direction. Figure 4 The discharge chute 20 is formed by enclosing a rod-shaped body 21 , and the fixed chute 51 and the movable chute 61 may also adopt a similar structure.

[0051] The embodiment of the present application also provides an inner cylinder loading device, including the fireworks inner cylinder discharging device provided in the previous part, and an inner cylinder transfer mechanism 90. The inner cylinder transfer mechanism 90 is used to transfer the inner cylinder pushed out by the fireworks inner cylinder discharging device into the fireworks body. For the fireworks inner cylinder discharging device, please refer to the description in the previous part, which will not be repeated here.

[0052] The embodiment of the present application also provides a fireworks production line, including the inner tube filling device mentioned above. It should be understood that the fireworks production line also needs to include other production equipment, such as paper filling and military gunpowder filling. The improvement of the present application involves the inner tube filling device, and the relevant content is described in the previous part, which will not be repeated here.
