Abstract

The utility model relates to the field of mechanical processing, and in particular to a paper-cutting device for the production of firecrackers. The technical problem is that the current paper-cutting device does not cut the firecracker paper smoothly and sufficiently, which leads to poor cutting effect and low efficiency of the firecracker paper. A paper-cutting device for the production of firecrackers includes an outer frame, both sides of the outer frame are slidably connected to a carrier frame, two compression springs are connected between the two carrier frames and the inner wall of the outer frame, and a carrier plate is fixedly connected to the two carrier frames. The utility model drives the extrusion rod to move by an electric slide rail. The movement of the extrusion rod causes the extrusion plate to squeeze the firecracker paper to fix it. The continued movement of the extrusion rod causes the extrusion plate and the carrier plate to pull the two sides of the firecracker paper, thereby making the middle part of the firecracker paper in a taut state, thereby making the subsequent cutting of the firecracker paper smoother, thereby improving the shearing effect of the firecracker paper.

Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a paper cutting device for firecracker production. Background Art

[0002] During the process of firecracker processing, the firecracker paper needs to be cut. In order to cut the firecracker paper more conveniently, the staff usually cut batches of firecracker paper together. During the cutting process, the staff will squeeze and fix the batches of firecracker paper to achieve the purpose of improving the cutting effect.

[0003] However, when the current paper-cutting device is used to cut the firecracker paper, it is not convenient to pull the firecracker paper to both sides while squeezing and fixing it, which causes the middle part of the firecracker paper to be loose, resulting in the cutting of the firecracker paper not being smooth enough, resulting in poor cutting effect of the firecracker paper. In addition, the existing paper-cutting device is not convenient for the shearing piece to move back and forth up and down while cutting, and the cutting form is relatively single, which results in insufficient cutting of the firecracker paper, resulting in low cutting efficiency of the firecracker paper. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the utility model provides a paper-cutting device for firecracker production, which can fix the firecracker paper and pull it to both sides to form tension so that the firecracker paper is cut more smoothly, and is convenient for reciprocating up and down while cutting the firecracker paper so that the firecracker paper is cut more fully.

[0005] The technical solution is as follows: A paper-cutting device for producing firecrackers, comprising an outer frame, two sides of the outer frame having long strips of openings, two sides of the outer frame being slidably connected with a carrier frame, the two carrier frames being symmetrically arranged, two compression springs being connected between the two carrier frames and the inner wall of the outer frame, two carrier plates being fixedly connected with a carrier plate, the inner wall of the outer frame being fixedly connected with an electric slide rail, the electric slide rail being slidably connected with an electric slider, the electric slider being fixedly connected with a limiting frame, the limiting frame being slidably connected with a sliding rod, a double-sided blade being fixedly connected with the bottom of the sliding rod, an extrusion assembly being provided on the carrier frame, the extrusion assembly being connected with the limiting frame, a reciprocating assembly being provided on the outer frame, the reciprocating assembly being connected with the double-sided blade, the electric slide rail driving the electric slider and the double-sided blade to move, the movement of the electric slider will cause the extrusion assembly to extrude and fix batches of firecracker paper, and the movement of the double-sided blade will cause the reciprocating assembly to drive the double-sided blade to repeatedly shear the firecracker paper up and down.

[0006] Optionally, the extrusion assembly includes a sliding frame, and the two sliding frames are respectively slidably connected to the two supporting frames. Two compression springs are respectively connected between the two sliding frames and the two supporting frames. The bottom of the two sliding frames are fixedly connected to an extrusion plate, and the limit frame is fixedly connected to an extrusion rod, and the two sides of the extrusion rod are respectively in contact with the top of the two sliding frames.

[0007] Optionally, the extrusion plate is made of rubber.

[0008] Optionally, the reciprocating component includes a limiting slide rail, which is fixedly connected to the bottom of the inner wall of the outer frame, and a wavy slide groove is formed on the limiting slide rail. A sliding block is fixedly connected to the bottom of the double-sided blade, and the sliding block is slidably connected to the wavy slide groove of the limiting slide rail.

[0009] Optionally, a pressure plate is also included, and the two pressure plates are respectively fixedly connected to one side of the top of the two limit frames.

[0010] The beneficial effects are: 1. The utility model drives the electric slider, the double-sided blade and the extrusion rod to move together through the electric slide rail. The movement of the extrusion rod will cause the extrusion plate to squeeze the firecracker paper downward to fix it through the sliding frame, so that the subsequent double-sided blade can cut the firecracker paper more stably. The continued movement of the extrusion rod will cause the two compression rods to be laterally squeezed so that the two extrusion plates and the two bearing plates pull the two sides of the firecracker paper, so that the middle part of the firecracker paper is in a taut state, so that the subsequent cutting of the firecracker paper is smoother, thereby improving the shearing effect of the firecracker paper.

[0011] 2. While the double-sided blade is shearing the firecracker paper, the movement of the sliding block will drive the double-sided blade to move back and forth up and down through the wavy groove of the limiting slide rail, so that the double-sided blade can repeatedly shear the firecracker paper up and down while moving, thereby shearing the firecracker paper more fully and improving the cutting efficiency of the firecracker paper.
