Description

Technical Field

[0001] This utility model relates to a processing device for straightening and cutting wound fireworks fuses into straight fuse segments, and then wrapping the straight fuse bundles. Background Technology

[0002] Firework fuses are typically produced by winding them into fuse coils. In actual production, the fuses in the fuse coils need to be straightened and cut into straight fuse segments, which can be 30 meters or longer. A large number (usually around 500) of these straight fuse segments are then bundled together to form a straight fuse bundle, which is then cut to the desired length for later use. Currently, all of these processes are done manually, resulting in low processing efficiency and a high labor load. Utility Model Content

[0003] To address the aforementioned drawbacks, the technical problem this utility model aims to solve is to provide a semi-automatic processing device that straightens and cuts wound firework fuses into straight fuse segments and wraps the straight fuse bundles, effectively improving processing efficiency and reducing labor load. To solve the above technical problem, the technical solution adopted by this utility model is a firework fuse bundling and wrapping device, comprising a fuse roll, a wrapping paper roll, and an annular transmission belt. The annular transmission belt is characterized by a fixed traction member, with the fuse end of the fuse roll connected to the traction member. Two uprights are provided within the annular transmission belt. The traction member rotates around the two uprights with the annular transmission belt, pulling out the fuse from the fuse roll and wrapping it around the two uprights. A flat belt is correspondingly provided below the fuse between the two uprights, rotating radially along the fuse. The end of the wrapping paper strip on the wrapping paper roll is laid on the flat belt. A reciprocating chuck is correspondingly provided above the flat belt.

[0004] The beneficial effect of this utility model is that, after the two ends of the lead wire between the two columns are manually cut into straight lead wire segments, each straight lead wire segment falls and is caught by a wrapping paper strip laid on a flat conveyor belt. The wrapping paper strip is manually glued and rolled into a single-layer paper tube to wrap each straight lead wire segment. The reciprocating rubbing plate and the rotating flat conveyor belt work together to rub the paper tube, so that the wrapping paper strip on the wrapping paper roll is continuously wrapped around the paper tube. After wrapping to the required number of layers, a wrapped lead wire bundle is obtained. This device can assist workers in completing the winding and straightening of lead wires and the processing of multi-layer paper wrapping of straight lead wire bundles, effectively improving processing efficiency and reducing labor load.

[0005] In the above technical solutions, the annular transmission belt may be an annular chain driven by a motor via a sprocket, an annular synchronous belt driven by a motor via a synchronous pulley, or an annular steel cable driven by a motor via a pulley.

[0006] In one embodiment, the flat belt is equipped with a tensioning mechanism. This prevents the bearing surface of the flat belt from sagging and affecting operation after bearing a large number of straight lead wire segments. In one embodiment, the tensioning mechanism includes a tensioning roller suspended inside the flat belt loop, a tensioning shaft arranged parallel to the tensioning roller, and two cables wound on the tensioning shaft. The two cables are connected to both ends of the tensioning roller. Rotating the tensioning shaft to wind up the two cables pulls down the tensioning roller, causing the bearing surface of the flat belt to be taut and straight.

[0007] In one embodiment, the washboard is connected to one end of the push rod, and the other end of the push rod is hinged to an eccentric shaft on an eccentric wheel. This allows the movement of the washboard to be adapted to agitate the paper tube. Furthermore, a magnetic suction assembly is provided below the push rod, comprising a magnet and a corresponding magnetic attracting element. The magnet is positioned below or on the push rod. The magnetic attracting element is made of iron; it can be an iron push rod body or an iron component attached to the push rod.

[0008] In one embodiment, the rubbing board has an inclined surface that abuts against the paper tube.

[0023] See appendix Figure 1-6 This illustrates a specific structure of the present invention. The fireworks fuse bundle wrapping device includes a fuse roll 702, a wrapping paper roll 1, and an annular transmission belt. In this example, the annular transmission belt is an annular chain 3, which surrounds a sprocket assembly 4 composed of four meshing sprockets. The annular chain 3 is driven to rotate by a first motor 2 through a drive sprocket 401 in the sprocket assembly.

[0024] A traction component 5—in this example, a wheel—is fixedly mounted on the annular chain 3. The end of the lead wire 7, unwound from the lead wire coil 702, is connected to the traction component 5. The annular chain 3 has a first post 801 and a second post 802 within its ring shape. The first post 801 and the second post 802 are arranged in a straight line, and the distance between the two posts corresponds to the required length of the straight lead wire segment. The illustration shows a small-scale device; in actual production, the length of the straight lead wire segment can reach 30 meters or even longer, and the distance between the first post 801 and the second post 802 can also reach 30 meters or even longer.

[0025] The traction component 5 rotates around the two columns with the ring chain 3, pulling out the lead wire 7 on the lead wire roll 702 and winding it around the two columns; a flat belt 6 is provided below the lead wire 7 between the two columns, and the second motor 16 drives the drive roller 601 to drive the flat belt 6 to rotate in the radial direction of the lead wire 7 (as shown by arrow A); the end of the wrapping paper strip 101 on the wrapping paper roll 1 is laid on the flat belt 6; a reciprocating slatter 11 is provided above the flat belt 6.

[0026] In the example, the washboard 11 is connected to one end of the push rod 9, and the other end of the push rod 9 is hinged to the eccentric shaft 12 on the eccentric wheel 13. This makes the reciprocating motion of the washboard 11 suitable for rubbing the paper tube 10. In the example, the middle part of the push rod 9 is suspended on the push rod tension spring 901.

[0027] In the example, the push rod 9 is made of iron, and a magnet 14 is provided below the push rod 9.

[0028] In the example, the flat belt 6 is equipped with a tensioning mechanism. This prevents the bearing surface of the flat belt 6 from sagging and affecting operation after bearing a large number of straight lead wire segments. The tensioning mechanism in the example includes a tensioning roller 602 suspended within the loop of the flat belt 6, a tensioning shaft 603 arranged parallel to the tensioning roller 602, and two cables 604 wound on the tensioning shaft 603. The two ends of the tensioning roller 602 are respectively connected to the two cables 604. Rotating the tensioning shaft 603 to wind up the two cables 604 will pull down the tensioning roller 602, making the bearing surface of the flat belt 6 taut and straight.

[0029] The working process of the above device is as follows:

[0030] S1: Start-up preparation: Before starting the machine, manually pull out the lead wire 7 from the lead wire roll 702 and fix the end of the lead wire 7 to the traction component 5; manually pull the wrapping paper roll 1 to lay the wrapping paper tape 101 on the flat belt 6.

[0031] S2: Start the first motor 2, which drives the annular chain 3 to rotate around the sprocket assembly 4 via the drive sprocket 401. The traction member 5 fixed on the chain 3 carries the lead wire 7 to rotate around the first column 801 and the second column 802, winding the lead wire 7 around the first column 801 and the second column 802. After rotating a set number of times, the first motor 2 stops. Manually cut off both ends of the lead wire 7 wound around the first column 801 and the second column 802. The large number of straight lead wire segments cut off are collectively referred to as the straight lead wire bundle 701. The straight lead wire bundle 701 is stacked on the wrapping paper tape 101.

[0032] S3: Manually perform initial wrapping of the straight lead wire harness 701 stacked on the wrapping paper tape 101: Specifically, apply glue under the end of the wrapping paper tape 101, wrap the end of the wrapping paper tape 101 tightly around the straight lead wire harness 701 and glue it into a paper tube 10 made of a single layer of paper.

[0033] S4: Start the second motor 18 to drive the active roller 601 of the flat belt 6 to make the flat belt 6 rotate;

[0034] The second motor 18 also drives the push rod 9 to reciprocate through the belt drive assembly 17, the drive shaft 18, and the eccentric wheel 13 in sequence. The rubbing plate 11 fixed on the push rod 9 abuts against the front upper part of the paper tube 10. In the example, the rubbing plate 11 has an inclined surface that abuts against the paper tube 10.

[0035] The reciprocating washboard 11, in conjunction with the rotating flat belt 6, rubs the paper tube 10, causing the wrapping paper strip 101 to continuously wrap around the paper tube 10. Generally, 3 to 5 layers are enough to complete the bundle wrapping of the firework fuse. The second motor 18 stops. The wrapping paper strip 101 is cut.

[0036] When the push rod 9 passes the magnet 14, the magnetic attraction causes the washboard 11 to press down on the paper tube 10, ensuring a tight wrap.

[0037] Manually rotating the turntable 605 causes the tensioning shaft 603 to wind up the cable 64, which in turn lowers the tensioning roller 602, tautling the receiving surface of the flat belt 6 to facilitate the ejection of the wrapped lead wire bundle from the flat belt 6. After ejection, it can be cut into pre-made sizes as needed.

[0038] As can be seen from the above, this device can assist workers in straightening the winding lead wire and processing the straight lead wire bundle with multiple layers of paper, effectively improving processing efficiency and reducing labor load.

[0039] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Obviously, many modifications and variations can be made based on the content of this specification. This specification selects and describes these embodiments in detail with reference to the accompanying drawings to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present invention. Therefore, the present invention is limited only to the claims and their full scope and equivalents, and not to the specific embodiments disclosed.
