Detailed Description of the Preferred Embodiments

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. For the convenience of narration, words such as "upper", "lower", "left" and "right" as used below only represent the same directions as the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.

[0023] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiments, such as Figures 1 to 7 As shown, the on-line waterless cleaning device for wire drawing provided by the present utility model includes a support frame 1 and a strip-shaped cleaning strip 2. The cleaning strip 2 can be impregnated with some cleaning agents, and the cleaning agents do not drip randomly from the cleaning strip 2. During the cleaning process before and after wire drawing of the wire 9, washing products mixed with water and surfactants and other components are not allowed to be used to avoid chemical reactions with the lubricating oil used in wire drawing production and prevent the wire 9 after wire drawing from rusting.

[0025] On this basis, the number of the cleaning strips 2 is greater than 2. A plurality of rollers 3 corresponding to the cleaning strips 2 one by one are arranged on the support frame 1. The rollers 3 are used to wind the cleaning strips 2. An installation shaft 4 connected to the support frame 1 is arranged at the center of the roller 3. A guide wheel 5 is also arranged on the support frame 1. A take-up and pay-off wheel 6 is arranged on one side of the guide wheel 5. A reduction motor 7 is arranged at the power end of the take-up and pay-off wheel 6. A main functional component 8 located on the wire drawing path of the wire 9 is arranged on one side of the support frame 1. A through hole 81 for passing through the wire 9 is arranged at the center of the main functional component 8. A guide hole 82 radially penetrating the through hole 81 is arranged on the side surface of the main functional component 8. The guide hole 82 is used to thread the cleaning strip 2 and make the working surface of the cleaning strip 2 contact the surface of the wire 9.

[0026] Specifically, each cleaning strip 2 corresponds to a roller 3. The cleaning strip 2 is led out from the roller 3. After the cleaning strip 2 is led out, it passes through different guide holes 82 respectively. And the guide holes 82 all penetrate the through hole 81. Therefore, different cleaning strips 2 contact the wire 9 in the through hole 81 at different axial nodes. During the process of the wire 9 being conveyed online, the wire 9 has a moving action in the same direction as the through hole 81. When the wire 9 and the cleaning strip 2 have relative movement, the cleaning is realized by the cleaning strip 2. The cleaning strip 2 itself has a certain degree of fluffiness. After it contacts the wire 9, it can effectively cover the base surface of the wire 9 per unit length. Coupled with more than one cleaning strip 2, the reasonable cleaning quality can be ensured. Further, the other end of the cleaning strip 2 bypasses the guide wheel 5 and is connected to the same take-up and pay-off wheel 6. The reduction motor 7 controls the number of turns of winding and unwinding of the take-up and pay-off wheel 6. By controlling the take-up and pay-off length of the cleaning strip 2, the actual working surface of the cleaning strip 2 can be effectively controlled, avoiding the situation that the cleaning strip 2 is worn and broken, realizing continuous cleaning, and having relatively high practicability.

[0027] In order to improve the utilization rate of the main functional component 8, the main functional component 8 provided by the present utility model includes at least 2 pairs of modular bases 83. The modular base 83 is in an isosceles trapezoid structure, and two modular bases are butted to form a hexagonal prism structure. The butting surface of the modular base 83 is provided with semi-holes 831 for forming through holes 81. The modular base 83 is provided with connection holes 832 penetrating through its butting surface. Assembly bolts 84 for installing and connecting two modular bases 83 are arranged in the connection holes 832. The modular base 83 is also provided with a plurality of positioning bolts 85 axially penetrating through its front and rear surfaces. Among them, the assembly bolts 84 are used to fix the same pair of modular bases 83, and the positioning bolts 85 are used to install the main functional component 8 on the production line equipment.

[0028] Furthermore, the present utility model is provided with dovetail grooves 833 for forming guiding holes 82 on the butting surface of the modular base 83. Both ends of the dovetail groove 833 penetrate through the edge of the butting surface of the modular base 83. In this way, the guiding holes 82 formed by each pair of dovetail grooves 833 can form a penetrating relationship with the through holes 81, facilitating the cleaning strip 2 to effectively contact the wire 9.

[0029] In order to improve the online cleaning efficiency and considering the quantity setting of the cleaning strips 2, the guiding holes 82 on the front and rear adjacent modular bases 83 provided by the present utility model are distributed at an angle of 60 degrees. In this way, different cleaning strips 2 can contact the wire 9 from different radial positions, effectively covering the entire circumferential surface of the wire 9, enabling the wire 9 moving online to form an effective cleaning contact surface with all the cleaning strips 2, improving the online cleaning efficiency of the device. Moreover, multiple cleaning strips 2 work simultaneously, with good contact and non-tangling characteristics, resulting in less frictional wear, which is beneficial to improving the actual service life of the cleaning strips 2 and the uninterrupted cleaning ability of the device.

[0030] In order to prevent the cleaning strips 2 from getting knotted, the present utility model designs all the rollers 3 on the support frame 1 into a rectangular array, thereby effectively spacing different cleaning strips 2 to give them sufficient spacing and avoid mutual entanglement on the lead-out path.

[0031] In order to improve the rotational stability of the roller 3, the present utility model is provided with bearings (not shown in the figure) inside the roller 3. The bearings are nested with the mounting shaft 4. The mounting shaft 4 is of a hollow structure and is provided with a plurality of axially spaced slots 41 on its side surface. Snap rings are arranged in the slots 41, and bearings cooperating with the mounting shaft 4 are arranged between the snap rings. The snap rings prevent the bearings from having a large range of axial movement on the mounting shaft 4 and affecting the lead-out effect of the cleaning strip 2.

[0032] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
