Description

Technical Field

[0001] This utility model relates to the technical field of wire winding equipment, specifically an automatic wire winding device. Background Technology

[0002] After the printing filament is extruded into shape by an extruder, it needs to be wound up by a spool. To ensure that the printing filament is wound tightly enough, a certain tension needs to be maintained on the filament during winding. As the amount of filament on the spool gradually increases, the diameter of the filament during winding increases. If the rotation speed (angular velocity) of the winding shaft remains constant, the linear velocity of the outer edge (the actual winding speed of the filament) will increase linearly with the increase of the filament diameter. This will cause a mismatch with the constant linear velocity of the previous process (such as drawing and extrusion), resulting in accumulation or overstretching. Secondly, the actual tension will decrease inversely with the increase of the filament diameter, resulting in a tight inner layer and a loose outer layer, and uneven winding.

[0003] This case arose in order to resolve the aforementioned issues. Summary of the Invention

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an automatic wire winding device, which solves the problems mentioned in the background section.

[0005] Technical solution To achieve the above objectives, this utility model provides the following technical solution: an automatic wire winding device, comprising a winding wheel driven by a motor for winding wire, a spreading mechanism provided on the front side of the winding wheel, which moves horizontally and reciprocally in real time under the driving force as the winding wheel winds, an elastic component provided on the spreading mechanism, the elastic component comprising a U-shaped support, the bottom of the support being fixed to the upper end of the threaded sleeve, and limiting seats being fixed on both sides of the inner wall of the support, with sliding blocks slidably connected to the limiting seats, and an adjusting wheel pivotally connected between the two sliding blocks, wherein the sliding blocks are buffered by springs.

[0006] Preferably, the evenly spreading mechanism includes a lead screw and a threaded sleeve, with the lead screw horizontally supported in front of the winding wheel and the threaded sleeve threadedly connected to the lead screw.

[0007] Preferably, the limiting seat is arranged vertically along the support, and a locking post is provided on the upper part of the inner wall of the support. The locking post is fixed to the side of the lower sliding block by a spring.

[0008] Preferably, it also includes a conductor assembly, which includes a rocker arm pivotally connected to the outer side of the support, with an abutment block in the middle and a pressure roller installed at the other end. The pressure roller has weight and applies downward gravity to the wire to keep it taut throughout the transmission process.

[0009] Preferably, the abutment block has a through groove, wherein the wire is wound around the pressure roller from the bottom, passes through the through groove on the abutment block upwards, and then passes around the upper side of the adjusting roller to enter the winding roller. Beneficial effects

[0010] By adopting the above technical solution, this utility model has the following advantages compared with the prior art: The automatic wire winding device of this utility model, with its elastic component, automatically reduces the tension setting value as the amount of wire on the spool gradually increases, maintaining a constant tension on the wire and avoiding excessive stretching. Simultaneously, the elastic reset tension of the adjusting wheel stabilizes the tension, preventing collapse, crossing, and gaps, thus improving winding quality. Furthermore, combined with the conductor assembly consistently applying initial pressure to the wire, the wire can maintain a tight, layered arrangement even during horizontal movement.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 As shown: An automatic wire winding device includes a winding wheel driven by a motor for winding wire. A spreading mechanism is provided on the front side of the winding wheel, which moves horizontally and reciprocally in real time under the driving force as the winding wheel winds. The wire moves horizontally synchronously with the spreading mechanism during winding to be evenly wound on the winding wheel.

[0015] The even-laying mechanism includes a lead screw and a threaded sleeve. The lead screw is horizontally supported in front of the winding wheel, and the threaded sleeve is threaded onto the lead screw, enabling translation during the rotation of the lead screw. An elastic component and a wire assembly are located on the upper side of the lead screw, which simultaneously adjust the actual tension of the wire during winding to maintain stable winding while driving the wire horizontally.

[0016] like Figure 2As shown: The elastic component includes a support, a spring, a sliding block, a limiting seat, and an adjusting wheel. The support is U-shaped, with its bottom fixed to the upper end of the threaded sleeve. The limiting seats are fixed to both sides of the inner wall of the support, and the sliding block is slidably connected to the limiting seat. The limiting seats are arranged vertically along the support, and the adjusting wheel is horizontally connected between the two sliding blocks via a support rod. A locking pin is located above the two inner walls of the support, and both ends of the spring are connected to the locking pin and the sliding block, respectively.

[0017] The conductor assembly includes a rocker arm, a pressure roller, and a contact block. The rocker arm is pivotally connected to the outer side of the support. The contact block is located in the middle of the rocker arm, and the pressure roller is installed at the other end. The pressure roller has a certain weight, which applies downward gravity to the conductor to keep it taut during transmission.

[0018] The wire is wound around the pressure roller from the bottom, passes through the through groove on the abutment block, and then goes around the top of the adjusting roller and connects to the winding roller to achieve winding.

[0019] When fluctuations occur during the winding process of the take-up reel, the tension of the wire harness will change. At this time, the rocker arm will rotate around the fixed axis to resist the influence of the above changes on the tension of the wire harness.

[0020] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
