Description

Technical Field

[0001] The utility model relates to the technical field of fireworks production, and in particular to a fireworks fuse safety cutting device. Background Art

[0002] In the process of fireworks production, fuse is an indispensable raw material. However, with the advancement of production technology, in mechanized large-scale production, bundles of fuse need to be pulled to processing equipment for use. Due to the flammable nature of fuse, protective devices need to be used during the pulling process to ensure the safety of the fuse during the pulling process and avoid fire caused by fuse burning. Utility Model Content

[0003] The purpose of the present utility model is to solve the problem in the prior art that due to the flammable nature of the fuse, a protective device needs to be used to protect the fuse during the pulling process, thereby ensuring the safety of the fuse during the pulling process and avoiding the problem of fire caused by fuse combustion. Therefore, a firework fuse safety cutting device is proposed, which includes two knives for cutting firework fuses that are close to each other. The ends of the two knives are integrally fixedly connected to a connecting plate, and a corresponding synchronously controlled cylinder is installed on the connecting plate. At least one side plate is provided on the side wall of each knife, and the side plate is equipped with a blowing assembly.

[0004] Preferably: the blowing assembly includes: an elastic bag, wherein the elastic bag is fixedly bonded to the side plate of one of the tools, the bonded elastic bag is located between the side plates of the two tools, the height of the elastic bag is higher than the distance between the side plates of the two tools, a chamber is provided inside the elastic bag, the chamber is connected to an air hole for outward air flow, and the direction of the air hole is directly facing the blades of the two tools.

[0005] Preferably, the elastic bag is made of memory rubber material. When the elastic bag is pressed down, it will be deformed and flattened, and when the pressure is stopped, the elastic bag will automatically return to its original state.

[0006] Beneficial effects: When in use, first place the firework fuse to be cut between the two cutters. At this time, the cylinder controls the two cutters to approach each other, the elastic bag is flattened, and the air in the elastic bag chamber will escape from the air hole. When the two cutters cut and produce tiny sparks that accidentally ignite the fuse, it will be blown out by the ejected air. At the same time, because the elastic bag is made of memory rubber material, it will be deformed and flattened when pressed down, and the elastic bag will automatically return to its original state when the pressure is stopped, so it can be reused.

[0010] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0011] Reference Figures 1 to 2 A fireworks fuse safety cutting device includes two cutters 1 for cutting fireworks fuses, which are close to each other. The ends of the two cutters 1 are integrally fixedly connected to a connecting plate 101, and the connecting plate 101 is equipped with a corresponding synchronously controlled cylinder 102. Each cutter 1 is provided with at least one side plate 2 on the side wall, and the side plate 2 is equipped with a blowing assembly.

[0012] Preferably, the blowing assembly includes an elastic bag 3, wherein the elastic bag 3 is fixedly bonded to the side plate 2 of one of the cutters 1, and the bonded elastic bag 3 is located between the side plates 2 of the two cutters 1. The height of the elastic bag 3 is higher than the distance between the side plates 2 of the two cutters 1. A chamber 301 is provided inside the elastic bag 3, and the chamber 301 is connected to an air hole 302 for outward air flow. The direction of the air hole 302 is exactly opposite to the blades of the two cutters 1. When in use, the fireworks fuse to be cut is first placed between the two cutters, and then the cylinder 102 that controls the two cutters 1 to be relatively close to each other is started. At this time, the cylinder 102 controls the two cutters 1 to be close to each other. At the same time, since the height of the elastic bag 3 is higher than the distance between the side plates 2 of the two cutters 1, when the two cutters 1 are combined for cutting, the side plates of the two cutters 1 will first contact the elastic bag 3 and flatten the elastic bag 3. At this time, when the elastic bag 3 is flattened, the air in the chamber 301 of the elastic bag 3 will go out from the air hole 302, and since the air hole 302 is small, the air will be ejected quickly and sprayed on the blades of the two cutters 1. At the same time, the two cutters 1 will also press down to cut off the fuse. When the two cutters 1 cut and produce a small spark to ignite the fuse, it will be blown out by the ejected air.

[0013] Preferably, the elastic bag 3 is made of memory rubber material. When the elastic bag 3 is pressed downward, it will be deformed and flattened, and when the pressure is stopped, the elastic bag 3 will automatically return to its original state.

[0014] Working principle: When in use, first place the fireworks fuse to be cut between the two cutters, and then start the cylinder 102 that controls the two cutters 1 to be relatively close to each other for cutting. At this time, the cylinder 102 controls the two cutters 1 to approach each other. At the same time, since the height of the elastic capsule 3 is higher than the distance between the side plates 2 in the two cutters 1, when the two cutters 1 are combined for cutting, the side plates of the two cutters 1 will first contact the elastic capsule 3 and flatten the elastic capsule 3. At this time, when the elastic capsule 3 is flattened, the air in the chamber 301 of the elastic capsule 3 will go out from the air hole 302, and since the air hole 302 is small, the air will be ejected quickly and sprayed on the blades of the two cutters 1. At the same time, the two cutters 1 will also press down to cut the fuse. When the two cutters 1 cut and produce a small spark to ignite the fuse, it will be blown out by the ejected air. Afterwards, as the two cutters 1 move away from the elastic capsule 3, which is made of memory rubber material, the elastic capsule 3 will be deformed and flattened when the pressure is stopped. When the pressure is stopped, the elastic capsule 3 will automatically return to its original state and can be reused.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
