Description

Technical Field

[0001] The utility model relates to the field of firecracker production equipment, in particular to a wire feeding and cutting mechanism of a firecracker machine. Background Art

[0002] The structure of firecrackers includes a launching tube, a fuse and gunpowder. When producing firecrackers, the firecracker machine needs to deliver the fuse to the launching tube and insert it into the launching tube, and then fill the launching tube with gunpowder. The delivery of the fuse and the control of the fuse length are very critical steps, and higher requirements are placed on the transmission stability of the fuse.

[0003] The existing firecracker production process needs to be installed manually one by one, which is inefficient and cannot meet the needs of mass production. Utility Model Content

[0004] In order to solve the above problems, the purpose of the present invention is to provide a wire feeding and cutting mechanism with precise control and high efficiency, thereby greatly improving production efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wire feeding and cutting mechanism of a firecracker machine, comprising a frame, wherein the frame is provided with a wire lead-in plate, a wire drive wheel assembly, a wire positioning input plate, a wire cutting assembly and a wire positioning output plate that can move up and down, the wire cutting assembly is installed on the wire positioning output plate, the wire lead-in plate is arranged with threading holes in a matrix, the wire positioning input plate and the lead positioning output plate are both provided with wire holes aligned one by one with the threading holes on the left and right, the wire cutting assembly comprises a left shearing plate and a right shearing plate, both sides of the left shearing plate and both side edges of the right shearing plate are provided with "V"-shaped shearing grooves evenly distributed in sequence, the "V"-shaped shearing grooves on the left shearing plate and the "V"-shaped shearing grooves on the right shearing plate are stacked up and down to form a shearing hole, the shearing hole is aligned with the threading hole, and the left shearing plate and the right shearing plate are driven by their respective cylinders.

[0006] The wire driving wheel assembly includes rollers arranged in sequence, which are driven by gear meshing. One gear is driven by a servo motor. An annular groove is provided on the roller, and the groove between the two rollers forms a wire threading clamping groove.

[0007] A lifting cylinder is installed on the lead wire positioning input plate, and a piston rod of the lifting cylinder is connected to the lead wire positioning output plate.

[0008] The threading holes on the lead-in plate are connected with wire tubes.

[0009] The beneficial effects of the present invention are as follows: after the lead coil is output, it passes through the threading hole on the lead introduction plate and can be pulled and transported by the lead driving wheel assembly, and then passes through the shearing hole in the wire cutting assembly between the lead positioning input plate and the lead positioning input plate. After the lead is transmitted to the specified position, the shearing hole shears and cuts the lead. Since the roller in the lead driving wheel assembly is driven by a servo motor, the technical purpose of precise and efficient control is achieved, thereby greatly improving production efficiency.

[0015] The present invention is described in detail below through examples, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0016] like Figure 1 — Figure 4 As shown, this embodiment discloses a wire feeding and cutting mechanism of a firecracker machine, including a frame 1, which is provided with a wire introduction plate 2, a wire driving wheel assembly 3, a wire positioning input plate 4, a wire cutting assembly 5 and a wire positioning output plate 6 that can move up and down. The wire cutting assembly 5 is installed on the wire positioning output plate 6. The wire introduction plate 2 is provided with a matrix of wire threading holes. The wire positioning input plate 4 and the lead positioning output plate 6 are provided with wire holes that are aligned with the wire threading holes on the left and right. The wire cutting assembly 5 includes a plurality of left shearing plates 51 and a plurality of left shearing plates 52. The right shear plate 52, both sides of the left shear plate 51 and the edges of both sides of the right shear plate 52 are provided with "V"-shaped shear grooves 50 evenly distributed in sequence. The "V"-shaped shear grooves 50 on the left shear plate 51 and the "V"-shaped shear grooves 50 on the right shear plate 52 are stacked up and down to form a shear hole 53, which is aligned with the threading hole. The left shear plate 51 and the right shear plate 52 are respectively connected to their respective mounting plates and driven by their respective cylinders 54. In this way, after the two cylinders 54 are extended and retracted, the lead wire passing through the shear hole 53 can be sheared.

[0017] The wire drive wheel assembly 3 comprises rollers 31 arranged in sequence. These rollers 31 are driven by meshing gears, one of which is driven by a servo motor 32. Alternatively, each roller is equipped with a pulley, which is connected to the servo motor 32 via a belt and pulley assembly. This ensures that adjacent rollers rotate in opposite directions. The rollers 31 are provided with an annular groove, and the groove between the two rollers 31 forms a wire threading and clamping groove 33. This structure allows for precise control of the roller 31's rotational speed and allows the wire to be positioned and delivered along the wire threading and clamping groove 33, effectively improving the stability and accuracy of its delivery.

[0018] A lifting cylinder 41 is mounted on the lead wire positioning input plate 4, and the piston rod of the lifting cylinder 41 is connected to the lead wire positioning output plate 6. The lifting cylinder can be used to separate the lead wire positioning output plate 6 from the lead wire positioning input plate 4, making it easier to clean debris or perform maintenance operations.

[0019] The wire threading hole on the lead-in plate 2 is connected with a wire tube 5. The wire tube 5 can avoid bending of the lead during insertion and ensure smooth reliability during transmission, thereby further improving the stability of lead transmission.

[0020] By adopting the above technical solution, after the lead coil is output, it passes through the threading hole on the lead introduction plate 2 and can be pulled and transported by the lead driving wheel assembly 3. Then, it passes through the shearing hole 53 in the wire cutting assembly 5 between the lead positioning input plate 4 and the lead positioning input plate 4. After the lead is transmitted to the specified position, the shearing hole 53 shears and cuts the lead. Since the roller 31 in the lead driving wheel assembly 3 is driven by the servo motor 32, the output distance of the lead can be precisely controlled so that it can be accurately extended into the launching tube inserted and positioned below the lead positioning output plate 6, achieving the technical purpose of precise and efficient control, thereby greatly improving production efficiency.

[0021] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive.

Any reference signs in the claims should not be construed as limiting the claim to which they relate.
