A molded firework loading and dispensing device

Abstract

The invention discloses a lead wire mounting and dispensing device of molded fireworks. The lead wire mounting and dispensing device comprises a lead wire mounting mechanism and a dispensing mechanism which are sequentially distributed on a transmitting mechanism. The lead wire mounting and dispensing device disclosed by the invention can be used for efficiently and reliably completing lead wire mounting and dispensing work of the molded firework, and efficiently and reliably completes lead wire mounting and dispensing work of one product once, has processing speed adaptive to and matched with other processes in large-scale assembly line production of the molded fireworks, protects the lead wire and greatly improves lead wire mounting quality. The dispensing mechanism can effectively prevent a glue path from being blocked, dispensing dose is uniform and adjustable, glue is reliably isolated from air in a glue supply process, and concentration of the glue is uniform. The whole device is simple in mechanism, is matched and coordinated smoothly, is convenient to operate, regulate and maintain, is low in cost, and is durable and wearable; and special requirements of the molded fireworks are met, and high-quality efficient automatic assembly line production is realized.

Description

technical field

[0001] The invention relates to a production equipment of molded fireworks, in particular to an automatic device for completing the installation and dispensing of lead wires of molded fireworks. Background technique

[0002] Molded fireworks refer to fireworks made by one-shot molding. The structure of this kind of firework can be referred to "A Molded Combination Firework" disclosed in Chinese invention patent document CN 102914223 A. The firework mode of the firework adopts the structure of fire transmission at the bottom. The closed end of the tubular cavity is provided with a fire transmission hole that runs through the bottom surface of the body. The bottom surface is provided with a wiring groove connecting the opening of the bottom surface of the fire transmission hole to protect the positioning lead. The lead wire is embedded in the wiring groove to connect to each fire transmission hole. Burn the above-mentioned launching pyrotechnic charge. The w...

Embodiment 1

[0030] Embodiment 1: see attached Figure 1-8 , reflecting a specific structure of the present invention, the lead wire installation mechanism 4 of the molded fireworks is installed on the assembly line, and the assembly line includes the input conveyor belt 1, the positioning conveyor belt 3, and the output slide plate 7 of the molded fireworks 8 connected in sequence. The feed cylinder 2 sends the molded fireworks 8 from the input conveyor belt 1 to the positioning conveyor belt 3; the discharge cylinder 6 sends the molded fireworks 8 from the positioning conveyor belt 3 to the output slide 7. A lead wire installation mechanism 4 and a glue dispensing mechanism 5 are arranged on the positioning conveyor belt 3 . Between the lead wire installation mechanism 4 and the lead wire reel 401, there is an assembly 402 for smoke alarm and its fire alarm to cut off the lead wire

[0031] The lead wire installation mechanism 4 includes a correspondingly arranged folding die cavity, a fo...

Embodiment 2

[0043] Embodiment 2: see attached Figure 9 . The difference from Embodiment 1 is that the wiring groove 11 of the processed molded fireworks 10 is composed of five rows of grooves. The lead-in part 12 and the lead-out part 13 of the wiring groove 11 are respectively located at two opposite corners of the bottom of the molded fireworks 10 . In order to avoid that a plurality of protruding rods are inserted at the same time so that the lead wires are pulled at the same time to cause damage or even tear off. The protruding rods of the folding die include a primary protruding rod 15 and a secondary protruding rod 14, the primary protruding rod 15 is connected to the first reciprocating drive assembly (not shown in the figure), and the secondary protruding rod 14 is connected to the second folding rod. Lead the reciprocating drive assembly (not shown in the figure). During work, the primary protruding rod 15 is first inserted into the corresponding cavity 18, and then the secon...

Embodiment 3

[0044] Embodiment 3: see attached Figure 10 . The difference from Embodiment 1 is that the wiring groove 21 of the processed molded fireworks 20 is composed of six rows of grooves. In order to avoid that a plurality of protruding rods are inserted at the same time so that the lead wires are pulled at the same time to cause damage or even tear off. The protruding rods of the folding die include primary protruding rods 23 and secondary protruding rods 22 . The primary protruding rod 23 is located in the middle of all protruding rods.

[0045] During work, the primary convex rod 23 is first inserted into the corresponding concave cavity 25; then the secondary convex rod 22 is inserted into the corresponding concave cavity 25, and inserted in two steps to fold the lead plate into a U-shaped zigzag reciprocating shape; then the two corner pieces 24 jobs. All the other are identical with embodiment 1.
