Description

Technical Field

[0001] This utility model relates to the technical field of winding devices, specifically a winding device for aluminum strip coils used in continuous extrusion production. Background Technology

[0002] Aluminum busbars are a common industrial material, widely used in various fields due to their lightweight, high thermal conductivity, and corrosion resistance. The main functions and applications of aluminum busbars are as follows: They are commonly used in power transmission systems, such as as conductive busbars in distribution cabinets, transformers, and switchgear; they replace copper busbars or cables in scenarios requiring high current transmission (such as factories and substations). They serve as supporting structures for mechanical equipment, solar panels, and building curtain walls; they can also be used as lightweight components in automobiles, high-speed trains, and aircraft (such as battery box brackets). They can be used as corrosion-resistant components in pipes and reaction vessels, and as rust-proof structural components in ships and offshore platforms. They serve as conductive busbars and heat dissipation structures for electric vehicle battery packs, and as lightweight components such as aircraft internal supports and wiring.

[0003] Aluminum strip coils are typically produced using a continuous extrusion process. The continuous extrusion process involves feeding the extrusion blank into the cavity of a continuous extruder. Under the action of friction, the roller groove bites the blank and pulls the metal toward the die hole. The friction generates extrusion stress near the die hole, forcing the metal to flow continuously out of the die hole, ultimately forming a continuous aluminum strip. After being wound up by a winding device, a coiled aluminum strip is obtained.

[0004] Before being wound up, aluminum strip coils need to be guided and tensioned to ensure they are taut and neatly arranged on the reel. Because aluminum strip coils come in various cross-sectional widths, improperly sized guide and tensioning rollers can lead to poor guiding performance, resulting in loose and uneven arrangement of the aluminum strips during winding, and in severe cases, scratches and surface damage. However, if a set of guide rollers is manufactured for each specification of aluminum strip, the number of guide rollers required is enormous, incurring significant production costs. Summary of the Invention

[0005] The purpose of this utility model is to address the problems existing in the prior art by providing a take-up device for continuous extrusion production of aluminum strip profiles. By using stacked and assembled guide tensioning rollers, it can be adapted to guide the take-up of aluminum strips of various widths. Combined with the take-up action of the horizontal reciprocating take-up reel, the aluminum strip is guided accurately, and the take-up is neat, tight and orderly, further ensuring the production quality of aluminum strip coils.

[0006] This utility model is achieved using the following technical solution:

[0007] A continuous extrusion production aluminum strip coil winding device includes a front guide mechanism and an automatic winding mechanism located behind the front guide mechanism. The front guide mechanism includes a support rod and a tension rod. The support rod is fixed to the ground or to the base of the automatic winding mechanism. The top of the support rod is hinged to the middle of the tension rod. A torsion spring is installed at the hinge point. The front and rear ends of the tension rod are respectively mounted with guide wheel shafts through guide wheel bearings. The guide wheel shafts are equipped with front and rear guide wheels. Both the front and rear guide wheels are composed of multiple composite wheels stacked together. Limiting wheels are stacked on both sides of the composite wheels. The guide wheel shaft ends are tightened and fixed by screwing in a mounting nut.

[0008] The aluminum strip first enters from the upper edge of the front guide wheel, then passes around the lower edge of the rear guide wheel, and finally enters the area of ​​the automatic winding mechanism's drum for winding. The tension rod is fixed to one end of the torsion spring, and the support rod is fixed to the other end of the torsion spring. The torque resistance of the torsion spring generates tension on the aluminum strip, keeping it taut as it enters the drum. Simultaneously, a precisely matched multi-layer combination wheel and limit wheel form a guide wheel of a specific width, ensuring the strip always travels in one direction and is accurately wound by the drum. The guide wheels are made of nylon, and the thickness of the combination wheels can be manufactured in various sizes: 3mm, 5mm, 10mm, 20mm, and 50mm, to meet various combination requirements.

[0009] The automatic winding mechanism includes a base and a body. A track is horizontally arranged on the base. The bottom of the body is fitted with wheels that support the body's movement on the track. A drive device is installed on the base to propel the body back and forth on the track. A winding shaft is mounted on the body via bearings. A drum for winding aluminum strips is installed at the extended end of the winding shaft. The other end of the winding shaft is connected to a winding drive motor via a winding reducer.

[0010] The horizontally reciprocating drum can evenly wind the aluminum strip onto the circumference of the drum, making the winding compact and neat.

[0011] The drive device is an electric push rod or a lead screw drive device. When an electric push rod is used, the rod seat of the electric push rod is connected to the base, and the piston rod of the electric push rod is connected to the machine body. When a lead screw drive device is used, the inside of the machine body is hollow and the bottom is open. The lead screw drive device includes a lead screw, which is installed in the machine body through a lead screw bearing. The lead screw nut is fixedly connected to the base through a mounting seat. The lead screw passes through and engages with the lead screw hole of the lead screw nut. One end of the lead screw is connected to a moving drive motor through a moving reducer.

[0012] The drive motor achieves horizontal reciprocating motion of the machine body through forward and reverse cycle switching.

[0013] Travel limit switches are installed at both ends of the machine body along the length of the track, and limit seats for triggering the travel limit switches are installed on the base corresponding to the positions of the travel limit switches.

[0014] The base is equipped with a cable chain frame, and a cable chain is installed inside the cable chain frame. One end of the cable chain is connected to the cable chain frame, and the other end of the cable chain is connected to the machine body. Power and control lines are installed inside the cable chain.

[0015] The extended end of the winding shaft is provided with an external thread and is fitted with a drum locking nut for locking the drum onto the winding shaft.

[0016] This take-up device for continuous extrusion production of aluminum profiles has the following advantages:

[0017] 1. This continuous extrusion aluminum strip coil winding device improves the accuracy of guide wheel matching with aluminum strip by adopting a modular assembly design. This solves the matching problem for multiple specifications of aluminum strips during extrusion, effectively reducing production costs. The modular guide wheel design facilitates easy disassembly and assembly, solving the management problem of multiple guide wheels for multiple specifications of aluminum strips, reducing guide wheel production costs, enabling rapid adjustment, and improving production efficiency. Combined with the winding action of the horizontal reciprocating winding reel, the aluminum strip is precisely guided, and the winding is neat, tight, and orderly, further ensuring the production quality of the aluminum strip coil.

[0018] 2. The modular guide wheel structure avoids the drawback of needing to process multiple guide wheels of different specifications when winding aluminum strips of different specifications, thus reducing production costs.

[0019] 3. The horizontal reciprocating motion mechanism in the equipment operates stably, has a compact structure, is easy to install and disassemble, and is convenient to maintain. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the invention will be clearly and completely described below with reference to the embodiments. The described embodiments are only a part of the present utility model, and not all of the embodiments. Example

[0028] A continuous extrusion production aluminum strip coil winding device includes a front guide mechanism and an automatic winding mechanism located behind the front guide mechanism. The front guide mechanism includes a support rod 2 and a tension rod 21. The top of the support rod 2 is hinged to the middle of the tension rod 21. A torsion spring 24 is installed at the hinge point. The front and rear ends of the tension rod 21 are respectively mounted with guide wheel shafts 61 through guide wheel bearings 65. The front guide wheel 22 and the rear guide wheel 23 are respectively mounted on the guide wheel shafts 61 at the corresponding ends. The front guide wheel 22 and the rear guide wheel 23 are both composed of multiple composite wheels 64 stacked together. Limiting wheels 63 are stacked on both sides of the composite wheels 64. The guide wheel shaft 61 is pressed and fixed by screwing in the mounting nut 62 at the end.

[0029] The automatic winding mechanism includes a base 1 and a body 51. A track 31 is horizontally arranged on the base 1. The bottom of the body 51 is fitted with wheels 32 that support the body 51 as it moves on the track 31. A drive device is installed on the base 1 to propel the body 51 to move back and forth on the track 31. A winding shaft 54 ​​is mounted on the body 51 via bearings. A drum 53 for winding aluminum strips is installed at the extended end of the winding shaft 54. The other end of the winding shaft 54 ​​is connected to a winding drive motor 52 via a winding reducer 55.

[0030] The drive device is a lead screw drive device. At this time, the interior of the machine body 51 is hollow and the bottom is open. The lead screw drive device includes a lead screw 35, which is installed in the machine body 51 through a lead screw bearing 34. The lead screw nut 36 is fixedly connected to the base 1 through a mounting seat 33. The lead screw 35 passes through and engages with the lead screw hole of the lead screw nut 36. One end of the lead screw 35 is connected to a moving drive motor 37 through a moving reducer 38.

[0031] Travel limit switches 41 are installed at the front and rear ends of the body 51 along the length of the track 31, and a limit seat 42 for triggering the travel limit switch 41 is installed on the base 1 corresponding to the position of the travel limit switch 41.

[0032] The base 1 is provided with a cable chain frame 43, and a cable chain 44 is installed inside the cable chain frame 43. One end of the cable chain 44 is connected to the cable chain frame 43, and the other end of the cable chain 44 is connected to the machine body 51. Power supply and control lines are installed inside the cable chain 44.

[0033] The extended end of the winding shaft 54 ​​is provided with an external thread and is fitted with a drum locking nut 56 for locking the drum 53 onto the winding shaft 54.

[0034] The working process of this utility model is as follows: After the extruded aluminum strip passes over the top of the front guide wheel, the rear guide wheel presses against the top surface of the aluminum strip, and then the drum winds up the aluminum strip. The power output by the winding drive motor drives the winding shaft to rotate after passing through the winding reducer, thereby driving the drum to rotate and realize the winding of the aluminum strip. Since the lead screw is fixedly installed, when the power output by the moving drive motor drives the lead screw to rotate, the lead screw moves inside the lead screw, thereby driving the machine body to move as a whole. When the travel limit switch at the front end touches the limit seat at the front end, the moving drive motor reverses, thereby driving the machine body to move backward. When the travel limit switch at the rear end touches the limit seat at the rear end, the moving drive motor rotates forward, thereby driving the machine body to move forward, thus neatly and orderly winding the aluminum strip into the drum.

[0035] The above description is not intended to limit the present utility model, nor is the present utility model limited to the above examples. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
