Description

Technical Field

[0001] The present application relates to the technical field of fireworks production equipment, and in particular to a transfer unit for fireworks inner tubes and an inner tube filling device. Background Art

[0002] The inner tube of a firework contains bright beads, gunpowder, filler, and a priming agent. When ignited, it creates various effects, such as a dazzling display of colors and various sounds. During the fireworks production process, the inner tube is inserted into the outer tube of the firework body. Firework inner tubes can be categorized into different types based on the desired effect (e.g., color, sound).

[0003] Most current firework inner tube loading devices utilize one or more transfer modules to transfer and load the inner tubes. During operation, a loading mechanism within the device first loads the inner tubes into the transfer module, which then transfers the inner tubes to the firework launch tube. During operation, a drive mechanism drives the transfer module between the loading mechanism and the firework launch tube to transfer the inner tubes discharged by the loading mechanism into the firework launch tube. In this type of device, the transfer module and the actuating mechanism are integrated, with the actuating mechanism driving the transfer module to move in a predetermined pattern, resulting in poor flexibility. Furthermore, in existing technology, each transfer module is often equipped with a baffle mechanism at its base, which can open or close the transfer module's loading port. This baffle mechanism is driven by a pneumatic cylinder, resulting in high cost and poor mobility. Utility Model Content

DETAILED DESCRIPTION

[0029] The following are specific embodiments of the present application and, in conjunction with the accompanying drawings, further description of the technical solutions of the present application is provided, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided solely to assist in a comprehensive understanding of the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope of protection of the present application. In addition, for clarity and brevity, descriptions of known functions and configurations have been omitted.

[0030] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0031] refer to Figure 1-Figure 3 The transfer unit 10 includes a base 11 and a transfer module 12 disposed on the base 11. The transfer module 12 is arranged with multiple rows of loading holes 121, and the base 11 is arranged with multiple rows of feeding holes 112 arranged in the same pattern as the rows of loading holes 121. The transfer module 12 and the base 11 are capable of relative movement to align or offset the loading holes 121 and the feeding holes 112. An elastic element 111 is disposed between the base 11 and the transfer module 12. The elastic force exerted by the elastic element 111 on the transfer module 12 and the base 11 maintains the offset between the loading holes 121 and the feeding holes 112. In one specific technical solution, the elastic element 111 is a spring.

[0032] Specifically, the multiple rows of loading holes 121 on the transfer module 12 can be used to load firework inner tubes; the base 11 is located below the transfer module 12. When the feeding holes 112 on the base 11 and the loading holes 121 on the transfer module 12 are staggered with each other, the firework inner tubes in the loading holes 121 are blocked by the base 11 and cannot fall out; when the feeding holes 112 on the base 11 and the loading holes 121 on the transfer module 12 are aligned with each other, the firework inner tubes in the loading holes 121 can fall out through the feeding holes 112 on the base 11. Therefore, the feeding holes 112 will only be aligned with the loading holes 121 when loading and dropping materials into the firework launch tube.

[0033] In one embodiment of the present application, the base 11 includes a bottom plate 113, and one or more first limit blocks 114 and one or more second limit blocks 115 arranged on the bottom plate 113; the first limit block 114 and the second limit block 115 are respectively located on opposite sides of the transfer module 12; the elastic element 111 is arranged between the transfer module 12 and the first limit block 114, and drives the transfer module 12 to press the second limit block 115. Under the action of the elastic element 111, the transfer module 12 is pressed toward the side of the second limit block 115. At this time, the loading hole 121 and the feeding hole 112 remain staggered. When the grasping mechanism grasps the base 11, the driving device 22 provided on the grasping mechanism can push the transfer module 12 to overcome the elastic force of the elastic element 111 and move toward the side of the first limit block 114 so that the loading hole 121 is aligned with the feeding hole 112. When the driving device 22 cancels the thrust, the transfer module 12 is pressed toward the second limit block 115 again under the action of the elastic element 111 , so that the loading hole 121 is staggered with the feeding hole 112 .

[0034] exist Figure 2 and Figure 3 In the structure shown, two first limit blocks 114 and two second limit blocks 115 are arranged on the bottom plate 113 , and a spring is arranged between each of the two first limit blocks 114 and the transfer module 12 .

[0035] In one embodiment of the present application, a plurality of limiting wheels 1110 are further arranged on the bottom plate 113; the plurality of limiting wheels 1110 are distributed on opposite sides of the transfer module 12, and are located on two sides different from the first limiting block 114 and the second limiting block 115; the limiting wheels 1110 on both sides are respectively abutted against the transfer module 12 to guide the transfer module 12 to move relative to the base 11. When the transfer module 12 moves relative to the base 11, the limiting wheels 1110 on both sides can rotate adaptively, which can reduce the movement resistance of the transfer module 12. Furthermore, at least two limiting wheels 1110 are arranged on each side of the two sides where the limiting wheels 1110 are arranged. Figure 2 and Figure 3 In the structure described above, three limiting wheels 1110 are respectively arranged on both sides of the transfer module 12 .

[0036] In one embodiment of the present application, the base 11 further includes: one or more first positioning blocks 116, one or more second positioning blocks 117; the first positioning block 116 and the second positioning block 117 are arranged on opposite sides of the transfer module 12 on the bottom plate 113, and are located on two sides different from the first limit block 114 and the second limit block 115; the first positioning block 116 and the second positioning block 117 are used to be clamped by a clamping mechanism. Furthermore, positioning holes 118 are provided on the first positioning block 116 and the second positioning block 117 for cooperative positioning when clamped by the clamping mechanism. Figure 2 and Figure 3 In the structure shown, two first positioning blocks 116 and two second positioning blocks 117 are arranged on the base plate 113, which are respectively located on opposite sides of the transfer module 12. When the grasping mechanism grasps the base 11, it clamps the first positioning block 116 and the second positioning block 117 from both sides to clamp the base 11.

[0037] In one embodiment of the present application, a pin hole 119 is further arranged on the base 11 for cooperating with the conveyor line. The pin hole 119 of the base 11 cooperates with the pin shaft on the conveyor line for positioning, thereby positioning the transfer unit 10 on the conveyor line.

[0038] Continue to refer Figures 4-10 The inner barrel filling equipment includes a transfer unit 10 and a gripping mechanism 20, wherein the transfer unit 10 includes a base 11 and a transfer module 12 arranged on the base 11; a plurality of rows of loading holes 121 are arranged on the transfer module 12, and a plurality of rows of feeding holes 112 are arranged on the base 11 in the same manner as the plurality of rows of loading holes 121; the transfer module 12 and the base 11 can move relative to each other so that the loading holes 121 and the feeding holes 112 are aligned or staggered one by one.

[0039] Specifically, the multiple rows of loading holes 121 on the transfer module 12 can be used to load firework inner tubes; the base 11 is located below the transfer module 12. When the feeding holes 112 on the base 11 and the loading holes 121 on the transfer module 12 are staggered with each other, the firework inner tubes in the loading holes 121 are blocked by the base 11 and cannot fall out; when the feeding holes 112 on the base 11 and the loading holes 121 on the transfer module 12 are aligned with each other, the firework inner tubes in the loading holes 121 can fall out through the feeding holes 112 on the base 11. Therefore, the feeding holes 112 will only be aligned with the loading holes 121 when loading and dropping materials into the firework launch tube.

[0040] The grabbing mechanism 20 is used to grab the transfer unit 10 and move it above the firework launch tube. It then aligns the loading hole 121 of the transfer module 12 with the firework launch tube, thereby dropping the firework inner tubes from the loading hole 121 into the firework launch tube. In one specific technical solution, the transfer unit 10 can be loaded multiple times on a conveyor line, capable of accepting a variety of firework inner tubes. The grabbing mechanism 20 then transfers the transfer unit 10 to the top of the firework launch tube W for emptying and loading.

[0041] When the grabbing mechanism 20 grabs the transfer unit 10 and moves it above the fireworks launching tube, and the loading hole 121 of the transfer module 12 is aligned with the fireworks launching tube, the feeding hole 112 on the base 11 is adjusted to be aligned with the loading hole 121 on the transfer module 12, so that the fireworks inner tube in the loading hole 121 passes through the feeding hole 112 on the base 11 and falls into the fireworks launching tube.

[0042] In one embodiment of the present application, the gripping mechanism 20 includes a gripper 21, a driving device 22, and a moving mechanism 23; wherein the gripper 21 is used to grip the transfer unit 10; the driving device 22 can apply action to the transfer unit 10 to cause the transfer module 12 and the base 11 to move relative to each other, thereby aligning or staggering the loading hole 121 with the feeding hole 112; the moving mechanism 23 is used to drive the gripper 21 and the driving device 22 to move.

[0043] The moving mechanism 23 is used to drive the gripper 21 and the driving device 22 to move, and can generally include a multi-directional motion mechanism, which can be set according to the actual solution. It should be understood that the moving mechanism is a common mechanical device in the prior art and will not be described in detail here.

[0044] The drive device 22 is used to apply motion to the transfer unit 10, causing the transfer module 12 and base 11 to move relative to each other, thereby aligning or misaligning the loading hole 121 with the feeding hole 112. When the gripping mechanism 20 grasps the transfer unit 10 and moves it above the firework launch tube, the drive device 22 applies motion to the transfer unit 10, aligning the loading hole 121 with the feeding hole 112. The firework inner tube in the loading hole 121 passes through the feeding hole 112 on the base 11 and is discharged into the firework launch tube. The drive device 22 can be configured in various ways as needed. In one specific technical solution, the drive device 22 is configured as a cylinder.

[0045] In one embodiment of the present application, the gripper 21 grasps the transfer unit 10 by applying a grasping operation to the base 11; the driving device 22 is used to apply an action to the transfer module 12 to drive the transfer module 12 to move when the gripper 21 grasps the base 11 so that the loading hole 121 is aligned or staggered with the feed hole 112.

[0046] An elastic element 111 is disposed between the base 11 and the transfer module 12. The elastic force exerted by the elastic element 111 on the transfer module 12 and the base 11 maintains the offset between the loading hole 121 and the feeding hole 112. When the gripper 21 grasps the base 11, the drive device 22 drives the transfer module 12 to overcome the elastic element 111 and move relative to it, aligning the loading hole 121 with the feeding hole 112. The elastic element 111 provides the elastic force and can be configured as a spring. Under the action of the elastic element 111, the loading hole 121 on the transfer module 12 and the feeding hole 112 on the base 11 remain offset.

[0047] The base 11 includes a bottom plate 113, and one or more first limit blocks 114 and one or more second limit blocks 115 arranged on the bottom plate 113; the first limit block 114 and the second limit block 115 are respectively arranged on opposite sides of the transfer module 12; the elastic element 111 is arranged between the transfer module 12 and the first limit block 114, and drives the transfer module 12 to press against the second limit block 115. Under the action of the elastic element 111, the transfer module 12 is pressed toward the side of the second limit block 115. At this time, the loading hole 121 and the feeding hole 112 remain staggered. The driving device 22 can push the transfer module 12 to overcome the elastic force of the elastic element 111 and move toward the side of the first limit block 114 so that the loading hole 121 is aligned with the feeding hole 112. When the driving device 22 cancels the thrust, the transfer module 12 is pressed toward the second limit block 115 again under the action of the elastic element 111 , so that the loading hole 121 is staggered with the feeding hole 112 .

[0048] The base 11 also includes one or more first positioning blocks 116 and one or more second positioning blocks 117; the first positioning block 116 and the second positioning block 117 are arranged on opposite sides of the transfer module 12 on the bottom plate 113, and are located on two sides different from the first limit block 114 and the second limit block 115; the gripper 21 clamps the first positioning block 116 and the second positioning block 117 from both sides to clamp the base 11.

[0049] When the gripper 21 is clamped on the first positioning block 116 and the second positioning block 117, the base 11 is clamped by the gripper 21. At this time, the driving device 22 is used to apply an action to the transfer unit 10, causing the transfer module 12 and the base 11 to move relative to each other, thereby aligning or staggering the loading hole 121 with the feeding hole 112. Specifically, the driving device 22 can push the transfer module 12 to overcome the elastic force of the elastic element 111 and move toward the first limit block 114 to align the loading hole 121 with the feeding hole 112. Furthermore, positioning holes 118 are arranged on the first positioning block 116 and the second positioning block 117; the gripper 21 is provided with a positioning pin 211 that is adapted to the positioning hole 118. When the gripper 21 is clamped on the first positioning block 116 and the second positioning block 117, the positioning pin 211 is inserted into the corresponding positioning hole 118.

[0050] In one embodiment of the present application, the inner tube loading device further comprises a push-down mechanism 30, which comprises a push-down member 31 and a drive element 32. The push-down member 31 is capable of being inserted downward into each loading hole 121 of the transfer module 12; the drive element 32 is used to drive the push-down member 31 during blanking and loading, so that the push-down member 31 pushes the firework inner tube downward in the loading hole 121.

[0051] When the gripping mechanism 20 grabs the transfer unit 10 and moves it above the firework launch tube, and the loading hole 121 of the transfer module 12 is aligned with the firework launch tube, the feeding hole 112 on the adjustment base 11 is aligned with the loading holes 121 on the transfer module 12. At this time, the driving element 32 can drive the push-down member 31 to move downward. The push-down member 31 is inserted downward into each loading hole 121 of the transfer module 12 and pushes down the firework inner tube in the loading hole 121. The push-down mechanism 30 can be used to ensure that the firework inner tube in each loading hole 121 falls out.

[0052] The driving element 32 can be configured as various types as needed. In one specific technical solution, the driving element 32 is configured as a cylinder. The push-down member 31 is provided with push rods corresponding to the loading holes 121. When the push-down member 31 moves downward, each push rod can be inserted into the corresponding loading hole 121.

[0053] The inner tube loading equipment also includes a conveyor line 200 and multiple loading mechanisms 300. The conveyor line 200 is used to transport the transfer unit 10; the multiple loading mechanisms 300 are used to load the transfer unit 10 on the conveyor line 200 with inner tubes. As the transfer unit 10 moves along the conveyor line 200, the multiple loading mechanisms 300 can load the transfer unit 10 with inner tubes. The multiple loading mechanisms 300 can load different types of firework inner tubes into the transfer unit 10. When the transfer unit 10 moves to a predetermined position, the gripping mechanism 20 grabs the transfer unit 10 and moves it above the firework launch tube, where it loads the firework inner tubes from the loading hole 121 into the firework launch tube.
