Description

Technical Field

[0001] This utility model relates to an unwinding device, and more particularly to an unwinding device for wire manufacturing, belonging to the field of wire manufacturing technology. Background Technology

[0002] In the wire processing production line, the unwinding machine is the core equipment at the front end. It is mainly responsible for smoothly and accurately unwinding the coiled wire, providing a continuous and stable supply of materials for subsequent processing steps.

[0003] The current unwinding machine only has a single guide roller at the middle of the front end. Although it can guide the wire, it has poor lateral restraint on the wire. In particular, thin wires are prone to deviating during the conveying process, which affects the conveying effect. In addition, the friction between the wire and the guide roller can easily generate static electricity, causing dust in the air to stick together and affecting the production quality of the wire.

[0004] To address this issue, an unwinding device for wire manufacturing was designed. Utility Model Content

[0005] The main objective of this invention is to provide an unwinding device for wire manufacturing to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] An unwinding device for wire manufacturing includes a mounting frame and an unwinding roller rotatably mounted at the rear end of the mounting frame. Guide rollers are rotatably mounted at the front end of the mounting frame on different horizontal planes. One end of the mounting frame is provided with a translation mechanism for adjusting the horizontal position of the guide rollers. An ionizing air bar is provided laterally at the front end of the mounting frame and at the top of the guide rollers. A dust removal mechanism is provided at the middle position of the front end of the mounting frame.

[0008] Preferably, the translation mechanism includes a strip groove, a slider, a screw, and a rotating shaft. The strip groove is horizontally arranged on both sides of the mounting frame, and two sets of strip grooves are opened on the sides of the mounting frame. A slider is slidably arranged inside the strip groove. A rotating shaft is rotatably installed between the side of the slider and the guide roller. A screw is rotatably installed between the two ends of the strip groove, and the screw is threadedly connected to the slider.

[0009] Preferably, one end of each screw extends to the front end of the mounting bracket, and the end of each screw located outside the mounting bracket is fixed with an adjusting wheel.

[0010] Preferably, the dust removal mechanism includes a negative pressure pump, a horizontal sleeve, an annular cavity, an air intake, a filter cylinder, and a filter element. The negative pressure pump is installed at the bottom of the mounting frame, and the output end of the negative pressure pump is connected to the end of the ion bar through a conduit. A horizontal sleeve is fixed at the middle position of the front end of the mounting frame. An annular cavity is opened inside the horizontal sleeve, and an air intake that communicates with the inside of the horizontal sleeve is opened on the outside of the annular cavity. A filter cylinder that communicates with the inside of the annular cavity is fixed at the bottom of the horizontal sleeve. A filter element is installed inside the filter cylinder, and the bottom end of the filter cylinder is connected to the input end of the negative pressure pump.

[0011] Preferably, the diameter of the end of the transverse sleeve closest to the unwinding roller is larger than the diameter of the other end, and the transition section inside the transverse sleeve is conical, with the annular cavity located outside the cone.

[0012] Preferably, the top of the filter cartridge is threaded to the bottom of the transverse sleeve, and the top of the outer side of the filter cartridge is uniformly provided with anti-slip texture along the circumference.

[0013] Preferably, there are four sets of air inlets evenly spaced, and the air inlets are funnel-shaped.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model provides guide rollers at the wire feeding end of the mounting frame. Two sets of guide rollers are located on different horizontal planes. The horizontal position of the guide rollers is adjusted by a translation mechanism. During the wire feeding process, the two sets of guide rollers form an "S" shaped path for the wire. Each set of guide rollers provides orthogonal constraint force. The offset is decomposed into multiple small corrections, upgrading the "passive blocking" of a single guide roller to "active guidance", which improves the correction effect during use. In addition, the translation mechanism can adjust the length of the formed "S" bend. The bending angle is large, the contact point between the wire and the guide roller is concentrated, the lateral constraint force is strong, and the response speed to sudden offset is fast.

[0016] 2. This utility model, by setting up an ion fan bar, can eliminate static electricity on the surface of the wire. Combined with a dust removal mechanism consisting of a negative pressure pump, a horizontal sleeve, an annular cavity, an air inlet, a filter cylinder, and a filter element, it can ensure the cleanliness of the wire surface. In addition, the negative pressure pump can not only provide negative pressure during dust removal, but also provide a stable air source for the ion fan bar, making it more practical.

[0030] Example 1

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes an unwinding device for wire manufacturing, including a mounting frame 1 and an unwinding roller 2 rotatably mounted at the rear end of the mounting frame 1. Guide rollers 3 are rotatably mounted at the front end of the mounting frame 1 and on different horizontal planes.

[0032] The guide roller 3 is made of aluminum alloy and the surface is anodized. The hardness is ≥200HV and the roughness Ra≤0.8μm. The guide roller 3 has an annular groove on its outer periphery with a groove width of 5mm and a depth of 2mm, which is used to limit the position of the wire.

[0033] One end of the mounting frame 1 is provided with a translation mechanism 4 for adjusting the horizontal position of the guide roller 3, and the front end of the mounting frame 1 and the top of the guide roller 3 are provided with an ion wind bar 5.

[0034] The ion bar 5 is model ST-507A, with an input voltage of 220V, an ionization frequency of 50Hz, and an outlet wind speed of ≥5m / s. It can eliminate static electricity within ±10kV on the surface of the conductor. The distance between the top of the ion bar 5 and the top of the guide roller 3 is 50mm to ensure that the airflow covers the surface of the conductor.

[0035] A dust removal mechanism 6 is provided at the middle position of the front end of the mounting bracket 1.

[0036] During unwinding, the wire passes through the bottom guide roller 3, then extends upward to the outside of the top guide roller 3, and then horizontally passes through the inside of the dust removal mechanism 6 for unwinding. The two sets of guide rollers 3 form an "S" shaped path for the wire. Each set of guide rollers 3 provides orthogonal constraint force, and the offset is decomposed into multiple small corrections, upgrading the "passive blocking" of a single guide roller 3 to "active guidance". In addition, the position of the guide rollers 3 can be adjusted by the translation mechanism 4 during use to change the length of the "S" bend. After the wire is corrected, the static electricity on the surface of the wire is eliminated by the ion air bar 5, and then the surface of the wire is cleaned by the dust removal mechanism 6.

[0037] Example 2

[0038] The solution in Example 1 will be further described below with reference to its specific working method.

[0039] like Figure 3As shown, in a preferred embodiment, based on the above method, the translation mechanism 4 further includes a strip groove 401, a slider 402, a screw 403, and a rotating shaft 404. The strip groove 401 is horizontally arranged on both sides of the mounting frame 1, and two sets of strip grooves 401 are opened on the sides of the mounting frame 1. The slider 402 is slidably arranged inside the strip groove 401. The rotating shaft 404 is rotatably installed between the side of the slider 402 and the guide roller 3. The screw 403 is rotatably installed between the two ends of the strip groove 401, and the screw 403 is threadedly connected to the slider 402.

[0040] When adjusting the position of the guide roller 3, manually rotate the screw 403 to control the slider 402 to slide horizontally inside the strip groove 401, thereby driving the guide roller 3 to move horizontally and adjusting the distance between the two sets of guide rollers 3.

[0041] like Figure 3 As shown, in a preferred embodiment, based on the above method, one end of each screw 403 extends to the front end of the mounting bracket 1, and an adjusting wheel is fixed to the end of each screw 403 located outside the mounting bracket 1. The use of the adjusting wheel allows for convenient manual adjustment.

[0042] like Figure 1 and Figure 4 As shown, in a preferred embodiment, based on the above method, the dust removal mechanism 6 further includes a negative pressure pump 601, a transverse sleeve 602, an annular cavity 603, an air intake 604, a filter cylinder 605, and a filter element 606. The negative pressure pump 601 is installed at the bottom of the mounting frame 1. The output end of the negative pressure pump 601 is connected to the end of the ion bar 5 through a conduit. The transverse sleeve 602 is fixed at the middle position of the front end of the mounting frame 1. An annular cavity 603 is opened inside the transverse sleeve 602. An air intake 604 is opened on the outside of the annular cavity 603 and is connected to the inside of the transverse sleeve 602. The filter cylinder 605, which is connected to the inside of the annular cavity 603, is fixed at the bottom of the transverse sleeve 602. The filter element 606 is installed inside the filter cylinder 605. The filter element 606 is a polypropylene filter screen with a pore size of 20μm and a filtration efficiency of ≥95% (for particles ≥5μm). It is removable and washable. The bottom end of the filter cylinder 605 is connected to the input end of the negative pressure pump 601.

[0043] Before the wire passes through the inside of the transverse sleeve 602, the negative pressure pump 601 is started. The output end of the negative pressure pump 601 provides a stable air source for the ion bar 5. The ion bar 5 is used to eliminate static electricity on the surface of the wire. Then the wire passes through the inside of the transverse sleeve 602. At this time, the adhesion force between the dust and the wire is small. A negative pressure is generated inside the filter cartridge 605. The dust adhering to the outer surface of the cable enters the filter cartridge 605 with the airflow and is filtered by the filter element 606.

[0044] like Figure 4As shown, in a preferred embodiment, based on the above method, the diameter of the end of the transverse sleeve 602 closest to the guide roller 3 is larger than the diameter of the other end, and the transition section inside the transverse sleeve 602 is conical. The annular cavity 603 is located outside the conical shape. When threading the wire, it is inserted from the end with the larger diameter and then passed out from the end with the smaller diameter, making the wire threading more convenient.

[0045] like Figure 4 As shown, in a preferred embodiment, based on the above method, the top end of the filter cylinder 605 is threaded to the bottom of the transverse sleeve 602, and the top end of the outer side of the filter cylinder 605 is uniformly provided with anti-slip texture along the circumference. The installation method of threaded connection makes disassembly and assembly more convenient.

[0046] like Figure 4 As shown, in a preferred embodiment, based on the above method, the air intake 604 is further provided with four sets evenly, and the air intake 604 is funnel-shaped with an inner diameter of 10mm and a funnel opening angle of 60°, to ensure that the airflow evenly covers the surface of the wire, and has a large air intake when sucking up dust, thereby improving the negative pressure suction effect of dust.

[0047] Example 3

[0048] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0049] During unwinding, the wire passes through the bottom guide roller 3, then extends upwards to the outside of the top guide roller 3, and then horizontally passes through the inside of the transverse sleeve 602 for unwinding. Two sets of guide rollers 3 form an "S" shaped path for the wire. Each set of guide rollers 3 provides orthogonal constraint force, and the offset is decomposed into multiple small-amplitude corrections, upgrading the "passive blocking" of a single guide roller 3 to "active guidance." Furthermore, during use, the adjusting wheel rotates the screw 403, controlling the slider 402 to slide horizontally inside the strip groove 401, thereby driving the guide rollers 3 to... The distance between the two sets of guide rollers 3 is adjusted by translation to change the length of the "S" bend. After the wire is corrected, the negative pressure pump 601 is started. The output end of the negative pressure pump 601 provides a stable air source for the ion air bar 5. The ion air bar 5 is used to eliminate static electricity on the surface of the wire. Then the wire passes through the inside of the transverse sleeve 602. At this time, the adhesion force between the dust and the wire is small. The inside of the filter cylinder 605 generates negative pressure. The dust adhering to the outer surface of the cable enters the filter cylinder 605 with the airflow and is filtered by the filter element 606 to thoroughly remove dust from the surface of the wire.

[0050] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
