Description

Technical Field

[0001] The utility model relates to cable processing equipment, in particular to a cable straightening device. Background Art

[0002] During the processing of cables, they need to go through multiple winding and unwinding operations. When the cable is left for a long time after winding and then unwinding, the unwound cable is prone to bending. If the next step is carried out directly, it will affect the processing quality. Therefore, it is generally necessary to perform straightening operations before continuing to the next step. The straightening operation generally uses a straightening wheel to straighten the cable. In order to improve the straightening efficiency, the cable will be heated before straightening. The heated cable has better straightening effect and higher efficiency. However, the temperature of the cable after straightening is still relatively high. The prior art generally uses natural drying to cool it down. However, this method has a low cooling effect and all the heat dissipates into the air, resulting in a waste of resources. Utility Model Content

DETAILED DESCRIPTION

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] It should be noted that, in the description of the technical solution of the present invention, some directional words used to clearly describe the technical features of the present invention, such as "front", "back", "up", "down", "top", "bottom", "inside", "outside", etc., are all in accordance with the orientation of the drawings of the present invention.

[0018] Example

[0019] like Figure 1As shown, a cable straightening device of this embodiment is used to heat and then straighten the cable 7, with good straightening effect and high efficiency. The device includes a preheating cylinder 1, a heating box 2, a straightening wheel assembly and a cooling device 6 arranged in sequence along the travel direction of the cable 7. The preheating cylinder 1, the heating box 2, and the cooling device 6 are all provided with through holes for the cable 7 to pass through. Among them, the preheating cylinder 1 has an annular preheating chamber 11, and the inner side wall of the preheating chamber 11 is penetrated by a plurality of hot air holes 12 evenly spaced, the air inlet end of the hot air hole 12 is connected to the preheating chamber 11, and the air outlet end 121 of the hot air hole 12 is connected to the outside. As shown Figure 2 As shown, the axis of the hot air hole 12 is arranged obliquely, and the air outlet end 121 of the hot air hole 12 is inclined in the direction away from the heating box 2. With this structural design, the preheated air flowing out through the hot air hole 12 is also inclined in the direction away from the heating box 2. Since the temperature of the preheated air is lower than the temperature in the heating box 2, this design can prevent the preheated air from entering the heating box 2 and affecting the heating efficiency of the heating box 2 on the cable 7. Moreover, after the preheated air is blown out obliquely, part of the preheated air can flow along the axial direction of the cable 7 and cover a larger range of the outer surface of the cable 7, thereby improving the preheating effect. Specifically in the present embodiment, when the angle between the axis of the hot air hole 12 and the axis of the cable 7 is in the range of 30-60 degrees, both a better preheating effect and a larger coverage range can be taken into account.

[0020] An electric heating tube is provided in the heating box 2, and the electric heating tube is connected to a power supply device. After the power supply device energizes the electric heating tube, the electric heating tube generates heat to heat the passing cable 7. The electric heating tube heating method adopted in this embodiment is a prior art, which is easy to use and has high heating efficiency, so it will not be described in detail here.

[0021] The straightening wheel assembly includes a plurality of rotatably mounted vertical straightening wheels 3 and horizontal straightening wheels 4. The rotatable mounting method of the vertical straightening wheels 3 and the horizontal straightening wheels 4 is prior art and will not be described in detail here. The vertical straightening wheels 3 and the horizontal straightening wheels 4 are arranged in pairs, and the gap between the two vertical straightening wheels 3 or the two horizontal straightening wheels 4 arranged opposite to each other matches the outer diameter of the cable 7, so as to be used for transmitting and straightening the cable 7.

[0022] The cooling device 6 includes a cooling box 61 and a cooling air duct 62. The cooling box 61 has a cooling cavity 611. The air outlet of the cooling air duct 62 is located in the cooling cavity 611 of the cooling box 61, and one end of the cooling air duct 62 extends to the outside of the cooling box 61 and is connected to the air outlet of the blower 63. Specifically, the cooling air duct 62 in this embodiment is spirally arranged on the outside of the cable 7, and a plurality of evenly distributed air outlet holes 621 are processed on the side of the cooling air duct 62 close to the cable 7. The axis of the air outlet hole 621 intersects with the axis of the cable 7 to ensure that the blown air can flow through the surface of the cable 7 and quickly take away the heat on the surface of the cable 7. The air outlet holes 621 are distributed along the spiral direction of the cooling air duct 62, so that the blown cooling air can effectively cover the entire outer circumferential surface of the cable 7, thereby cooling the cable 7 more efficiently.

[0023] Since the cooling box 61 is covered on the outside of the cooling air duct 62, the cooling air blown out of the cooling air duct 62 will still remain in the cooling box 61 after passing through the surface of the cable 7. After passing through the surface of the cable 7, the cooling air takes away the heat from the surface of the cable 7 and the temperature rises to form hot air. In order to prevent these hot air from affecting the cooling effect of the cooling air duct 62 on the cable 7, the present embodiment is connected to the cooling box 61 with an air collecting pipe 5, one end of which is connected to the inside of the cooling box 61, and the other end is connected to the inside of the preheating cylinder 1 and communicates with the hot air hole 12 of the preheating cylinder 1. With this structural design, the hot air in the cooling box 61 can enter the preheating cylinder 1 through the air collecting pipe 5 and be blown out through the hot air hole 12 to preheat the cable 7 before heating. This can not only reduce the adverse effect of the hot air remaining in the cooling box 61 on the cooling effect, but also improve the heating efficiency of the cable 7 to be straightened, and can also reduce energy waste, which is more environmentally friendly. In order to improve the air collecting effect of the air collecting pipe 5 in this embodiment, the portion of the air collecting pipe 5 extending into the interior of the cooling box 61 is designed to be a trumpet-shaped structure that is narrow at the top and wide at the bottom.

[0024] When in use, the cable 7 is preheated by the preheating cylinder 1 and then enters the heating box 2 for heating, and then is straightened by the straightening wheel assembly. The cable 7, which is still at a high temperature after straightening, is cooled by the cooling device 6, and the hot air that takes away the heat from the surface of the cable 7 is collected by the air collecting pipe 5 and returned to the preheating cylinder 1.

[0025] The utility model provides a cable straightening device, which cools the outer surface of the cable 7 in all directions through a cooling air duct 62 spirally arranged on the outside of the cable 7, and has high cooling efficiency; the wind that takes away the heat is collected by a cooling box 61 covered on the outside of the cooling air duct 62, and the hot air is transported through an air collecting pipe 5 connected between the cooling box 61 and the preheating cylinder 1, so that the hot air enters the preheating cylinder 1 to form preheating wind, and preheats the cable 7; the overall structural design is ingenious and reasonable, which improves the cooling effect and cooling efficiency, while improving the energy recovery rate, and is more environmentally friendly.

[0026] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the utility model.
