DETAILED DESCRIPTION

[0035] 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.

[0036] 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.

[0037] An embodiment of the present application provides a firework tube punching and inserting device, which is used to punch holes in two adjacent paper tubes and insert leads.

[0038] refer to Figure 1-Figure 3 The firework tube punching and inserting device comprises a frame 10, a punching mechanism 20, a wire blocking mechanism 30, and an inserting and guiding mechanism 40. The punching mechanism 20 is used to process a lead wire hole on the firework tube, and the wire blocking mechanism 30 and the inserting and guiding mechanism 40 cooperate to push the lead wire into the lead wire hole.

[0039] refer to Figure 4 The punching mechanism 20 includes a punching needle 21 and a first driving source 22. The first driving source 22 is used to drive the punching needle 21 to operate so as to form a lead hole on the firework tube. The first driving source can be electric, pneumatic, hydraulic, or other forms of driving sources. In a specific embodiment, the first driving source is a cylinder.

[0040] The wire blocking mechanism 30 includes a second movable frame 31, which is provided with a material blocking member 32 and a passive member 33. The material blocking member 32 can move with the second movable frame 31 to advance to the first position to support and limit the lead wire fed thereto or retreat to the second position to remove the support and limit for the lead wire.

[0041] The plug-in mechanism 40 includes a first moving frame 41 and a second driving source 46. The second driving source 46 is used to drive the first moving frame 41 to move. The first moving frame 41 is provided with a plug-in member 42 and a driving member 43. The plug-in member 42 can move with the first moving frame 41 to push the lead wire into the lead wire hole after the stopper 32 removes the support limit. The second driving source can be electric, pneumatic, hydraulic, or other forms of driving sources. In a specific solution, the second driving source is a cylinder.

[0042] During operation, first, the material blocking member is located in the first position, the wire feeding mechanism feeds the lead wire to the top of the material blocking member 32, the material blocking member supports and limits the lead wire above it, the cutting mechanism is used to cut the lead wire, the material blocking member 32 retreats to the second position to remove the support and limit for the lead wire, the insertion member 42 is used to push the lead wire into the lead wire hole after the material blocking member 32 removes the support and limit, the above working process involves the action coordination between the wire blocking mechanism and the insertion mechanism, through the action coordination between the wire blocking mechanism and the insertion mechanism, the lead wire sent by the wire feeding mechanism is continuously inserted into the firework paper tube.

[0043] When the second driving source 46 drives the first moving frame 41 to move, the driving member 43 acts on the passive member 33 to make the second moving frame 31 move in conjunction with the first moving frame 41. In this solution, the driving member acts on the passive member, so that the wire blocking mechanism can move with the plug-in mechanism. Only one driving source is needed to drive the first moving frame, which reduces the cost. Moreover, the mechanical linkage between the wire blocking mechanism and the plug-in mechanism is realized through the interaction between the driving member and the passive member, which makes the cooperation between the wire blocking mechanism and the plug-in mechanism more reliable.

[0044] In one embodiment of the present application, the wire blocking mechanism further includes an elastic reset member, which acts on the second movable frame 31. When the second driving source 46 drives the first movable frame 41 to move downward, the driving member 43 acts on the passive member 33 to make the second movable frame 31 retreat to overcome the elastic reset member, and the material blocking member 32 retreats to the second position with the second movable frame 31 to remove the support limit for the lead wire, so that the plug-in member 42 can push the lead wire with the support limit removed downward into the lead wire hole. When the second driving source 46 drives the first movable frame 41 to move upward, the driving member 43 separates from the passive member 33, and under the action of the elastic reset member, the material blocking member 32 advances to the first position with the second movable frame 31.

[0045] Specifically, when the second driving source 46 drives the first moving frame 41 upward to separate the driving member 43 from the passive member 33, the second moving frame 31 is reset under the action of the elastic reset member, and the material stopper 32 advances to the first position and stays at the first position. The elastic reset member applies an elastic force to the second moving frame 31 to keep the material stopper on the second moving frame 31 at the first position. When the second driving source 46 drives the first moving frame 41 downward, the driving member 43 comes into contact with the passive member 33, driving the second moving frame 31 to retreat to the second position, removing the support limit for the lead wire. At this time, the plug-in member 42 continues to move downward to push the lead wire with the support limit removed downward into the lead wire hole.

[0046] It should be noted that in the process of the second driving source 46 driving the first movable frame 41 to move downward, the plug-in member 42 and the driving member 43 move downward at the same time. The driving member 43 is used to act on the passive member 33 to make the second movable frame 31 overcome the elastic reset member and retreat, and the plug-in member 42 is used to push the lead wire downward into the lead wire hole. By the simultaneous action of the two, the lead wire can be smoothly pushed downward into the lead wire hole.

[0047] refer to Figure 5-Figure 7 The frame 10 is provided with a guide head 11, and the guide head 11 is provided with a gap groove 13 for inserting the lead-in member 42, and a pinhole 14 for the punching needle 21 to pass through. With the movement of the second moving frame 31, the stopper 32 can enter the gap groove 13 through the opening on the guide head 11 to support and limit the lead wire sent into the gap groove 13, or exit the gap groove 13. Specifically, the stopper 32 is provided on the opening on the guide head 11, and can extend into the gap groove 13 or be pushed out from the gap groove 13. The wire feeding mechanism feeds the lead wire into the gap groove 13 above the stopper 32.

[0048] In a specific embodiment, the guide head 11 is provided with a guide post 12 for guiding the movement of the second movable frame 31, and the elastic reset member is a spring, which is sleeved on the guide post 12. The guide head 11 includes a first support 111 and a second support 112, which are connected together to form a gap groove 13 therebetween, the pinhole 14 is arranged on the first support 111, and the guide post 12 is arranged on the second support 112. Specifically, in a specific solution, the spring is in a compressed state, and the elastic force provided by the spring is applied to the second movable frame 31, so that the second movable frame has a tendency to move toward the side close to the gap groove, so that after the driving member 43 is separated from the passive member 33, the material blocking member 32 can move to the first position and stay at the first position.

[0049] like Figure 6As shown, in one embodiment of the present application, the passive member 33 is a roller, and the roller is rotatably mounted on the second movable frame 31. When the second driving source 46 drives the first movable frame 41 to move downward, the driving member 43 acts on the roller to make the second movable frame 31 move backward. Furthermore, the driving member 43 is provided with an inclined surface 44 on the side facing the roller. When the second driving source 46 drives the first movable frame 41 to move downward, the inclined surface 44 presses against the roller to force the second movable frame 31 to move backward. When the driving member contacts and interacts with the roller, the roller can rotate. Here, setting the passive member 33 as a roller can make the interaction between the driving member and the passive member smoother and avoid jamming.

[0050] Further referring to 5, two insertion pins 45 are arranged on the first movable frame 41. The two insertion pins 45 are respectively located on both sides of the insertion member 42 and extend in the same direction as the insertion member 42. The two insertion pins 45 are used to bend the two ends of the lead wire S on the material stopper 32 downward. The two insertion pins 45 are slidably matched with the insertion member 42, and the first movable frame 41 drives the insertion member 42 to move downward through an elastic element 47. Specifically, the insertion member 42 can slide up and down relative to the insertion pins 45 on both sides, and the first movable frame 41 drives the insertion member 42 to move downward through an elastic element 47. Therefore, when the insertion member 42 encounters the material stopper and the paper tube, the elastic element 47 can be elastically deformed so as to stop the insertion member from moving and avoid rigid impact. In a specific embodiment, the elastic element 47 is a spring.

[0051] During the downward movement of the first moving frame 41, the plug-in member 42 is driven by the elastic element 47 to move downward and press on the stopper, and the lead wire is pressed between the plug-in member and the stopper. At this time, the cutting mechanism cuts off the lead wire. At the same time, the plug-in needles 45 on both sides continue to move downward, and the two ends of the lead wire on the stopper 32 are bent downward, so that the two ends of the lead wire sag to form an "n" shape. Then, the stopper 32 retreats to the second position with the second moving frame 31 to remove the support limit for the lead wire, and the plug-in member 42 pushes the lead wire with the support limit removed downward into the lead wire hole.

[0052] refer to Figure 1 and Figure 2 In one embodiment of the present application, the insertion needle 45 is arranged vertically and the punching needle 21 is arranged obliquely.

[0053] refer to Figure 8 The embodiment of the present application also provides a firework tube punching and inserting device, which includes the firework tube punching and inserting device provided in the previous part, a wire feeding mechanism 50, and a cutting mechanism 60, wherein the wire feeding mechanism 50 is used to transport the lead wire to the material blocking member 32, and the cutting mechanism 60 is used to cut the lead wire, and is located between the firework tube punching and inserting device and the wire feeding mechanism 50.

[0054] When working, the punching mechanism 20 is used to process the lead wire hole on the firework tube, and the wire blocking mechanism 30 and the insertion mechanism 40 cooperate to push the lead wire into the lead wire hole. The wire feeding mechanism 50 is used to convey the lead wire to the material blocking member 32, and the cutting mechanism 60 continuously cuts the lead wire conveyed by the wire feeding mechanism 50. With the cooperation of the above multiple mechanisms, the firework tube punching and insertion device can continuously punch holes in the firework tube and insert the lead wire.
