[0008] Preferably, the air flow nozzles are columnar pipe openings protruding at the roller surfaces of the brush rollers; along the axial direction of the brush rollers, a space between two adjacent air flow nozzles forms a path for the aluminum wire to travel.

[0009] Preferably, each air flow nozzle arranged along the axial direction of the brush rollers forms a nozzle unit, and each nozzle unit is uniformly distributed in a circumferential direction on the roller surface of the brush roller.

[0010] Preferably, the fixed ends of the brush rollers are rotationally fitted on a positioning frame, and the two fixed ends are arranged with power gears meshing with each other; a power motor is coaxially installed at the fixed end of one group of brush rollers and transmits power to the other group of brush rollers through the power gears.

[0011] Preferably, the positioning frame comprises a plumb plate for installing the fixed ends, an inner plate surface of the plumb plate is used for arranging the brush rollers, and an outer plate surface of the plumb plate extends outwardly with a motor fixing frame to install the power motor; the plumb plate is installed at a horizontal plate, the horizontal plate is arranged with a first oblong hole with a length direction of the hole parallel to the axis of the brush rollers, a first adjusting screw is screwed at the bottom surface of the plumb plate after being downwardly and upwardly penetrating through the first oblong hole; the positioning frame further comprises a positioning plate directly installed on the frame and horizontally arranged, the positioning plate is arranged with a second oblong hole with a length direction of the hole vertical to the axis of the brush rollers, and a second adjusting screw is screwed on the frame after being upwardly and downwardly penetrating through the second oblong hole.

[0012] Preferably, the plumb plate is slidingly fitted with an upper sliding block and a lower sliding block, and the upper sliding block and the lower sliding block are respectively rotationally fitted with the shaft portions of the two groups of brush rollers; the plumb plate is arranged with a third oblong hole with a length direction of the hole vertically arranged at the plate side, and a third adjusting screw is screwed at the corresponding sliding block after being horizontally penetrating through the third oblong hole, so as to achieve the adjusting purpose of the vertical direction of the corresponding brush roller.

[0013] Preferably, the dust removal and collection section further comprises a cover box arranged on the brush rollers in an upper and lower manner; a dust suction port in the shape of a horn mouth is arranged below the brush rollers and opens upwardly; the aluminum powder passes through the dust suction port into a dust suction pipe and is collected into an external dust collection device through the dust suction pipe; the dust suction pipe, the dust suction port and the external dust collection device jointly form the negative pressure dust collection part.

[0014] Preferably, the cleaning liquid source comprises a cleaning liquid containing tank and a liquid conveying pipeline, an outlet end of the liquid conveying pipeline being communicated with the felt part at the coating section; a peristaltic pump for pumping the cleaning liquid is arranged on the liquid conveying pipeline.

[0016] The beneficial effects of the present application are as follows:

[0017] 1) For the specific situation that the drawing liquid residue and aluminum powder are mixed in the drawn aluminum wire, the present application specifically proposes a processing structure, that is, the arrangement of the coating section, the wiping section, the hot air drying section and the dust removal and dust collection section, the coating section realizes the cleaning liquid coating and dissolving function to realize the dissolving purpose of the drawing liquid, the wiping section realizes the wiping effect of the dissolved drawing liquid and simultaneously has the function of removing the surface aluminum powder, the hot air drying section is used for further drying the cleaning liquid to provide guarantee for the subsequent rolling brush work; finally, the dust removal and dust collection section has the scraping and removing effect on the residual aluminum powder after the drawing liquid is stripped, and the removed aluminum powder is reliably collected by the negative pressure dust collection part to avoid safety accidents caused by the escape of aluminum powder.

[0018] Therefore, the present application solves the mixing problem of the drawing liquid and aluminum powder on the surface of the drawn aluminum wire and realizes the efficient cleaning effect of the aluminum powder on the surface of the aluminum wire.

[0019] 2) As a further preferred embodiment of the above-mentioned scheme, the entire dust removal and dust collection section has the final complete cleaning function of the aluminum powder. Therefore, while maintaining the conventional rolling brush removing effect, the present application arranges the rolling brush as a cantilever structure and relies on the rotary joint to realize the air supply function. In this way, on the one hand, the rolling brush can rely on the bristles to ensure the scraping of the aluminum powder; on the other hand, the aluminum powder can be quickly separated from the bristles by relying on the airflow nozzle to blow along the direction of the bristles, and the aluminum powder is captured by the negative pressure dust collection part, so as to ensure the cleanliness of the bristles and ensure the maximum and efficient aluminum powder removing effect on the subsequent aluminum wire.

[0020] 3) Considering the blowing effect of the airflow nozzle, the aluminum wire is preferably arranged between adjacent airflow nozzles; at the same time, the nozzle unit should be multiple and circumferentially distributed to ensure the cleaning purpose.

[0021] 4) For the roller brush, the actual structure is an active brush driving a passive brush, with power transmission achieved through the meshing of a power gear. Simultaneously, the XY-axis adjustment system formed by the vertical plate, horizontal plate, and positioning plate ensures the planar position adjustment of the roller brush. Furthermore, the upper and lower sliders, in conjunction with the third adjusting screw, allow for adjustment of the Z-axis (vertical direction) movement of the two roller brushes, ultimately ensuring flexibility in adjustment.

[0022] 5) Considering the characteristics of the aforementioned roller brush and blowing operation, a cover box can be further arranged to avoid excessive dispersion of aluminum powder; the opening of the cover box is preferably as close as possible to the dust suction port to ensure that the dust suction port effectively captures aluminum powder.

[0023] 6) The cleaning liquid source can be in drip form or in the form of peristaltic pump as described in this invention, as long as the felt part is wetted. The hot air drying section can adopt a conventional drying box combined with a hot air blower, which will not be described in detail here. Attached Figure Description

Detailed Implementation

[0033] For ease of understanding, this section combines... Figures 1-3 The specific structure and working method of this utility model are further described below:

[0034] As Figure 1 shown, the utility model is arranged at the outlet of the wire drawing machine, and comprises a coating section 10, a wiping section 20, a hot air drying section 30 and a dust removal and collection section 40 arranged in sequence along the running direction of the aluminum wire a. Among them:

[0035] The coating section 10 and the wiping section 20 both comprise a felt part. In actual operation, a layer of white cloth is further covered on the working surface of the felt part to improve the coating and wiping effect and facilitate the inspection at any time. In addition, the coating section 10 adopts a pump machine, that is, the cleaning liquid source comprises a cleaning liquid containing box 11 with built-in cleaning liquid and a liquid delivery pipeline 12 with a peristaltic pump 13. Figure 1 It can be known that the coating section 10 adopts a pump machine, that is, the cleaning liquid source comprises a cleaning liquid containing box 11 with built-in cleaning liquid and a liquid delivery pipeline 12 with a peristaltic pump 13. Of course, in actual operation, a drop-by-drop mode can also be appropriately used, that is, the cleaning liquid is dropped by using gravity to realize the continuous liquid supplementing effect of the felt part.

[0036] For the hot air drying section 30, it has a drying effect on the cleaning liquid of the previous process to avoid the residual cleaning liquid on the surface of the wire body. In this way, after the aluminum wire a is first coated with cleaning liquid by the coating section 10 to dissolve the wire drawing liquid, the wire drawing liquid is wiped by the wiping section 20, and then the residual cleaning liquid enters the drying box 31, and the moisture is dried by the air heater 32, and finally enters the dust removal and collection section 40.

[0037] The structure of the dust removal and collection section 40 is shown in Figures 1-3 , which comprises upper and lower arranged roller brushes 41, and the aluminum wire a can pass between the two roller brushes 41. Considering the continuous working ability of the roller brush 41 and how to maintain the cleanliness of the bristles 41a in the continuous working state, the air flow nozzle 41b is further arranged on the roller brush 41, and the air source is introduced into the hollow cavity 41c through the rotary joint. While the air flow nozzle 41b sweeps the bristles 41a and even the aluminum powder on the surface of the aluminum wire a, the outward escaping aluminum powder is hindered by the cover box 47, and is collected by the dust suction port 48, and then enters the external dust collection equipment through the dust suction pipe, to achieve the aluminum powder removal effect.

[0038] Of course, considering that the dust removal and dust collection section 40 and the like are all installed on the rack of the wire drawing production line, the position adjustment function of the roller brush 41 needs to be realized here. Therefore, while the roller brush 41 itself relies on the power motor 43 and the power gear 42 to realize the basic working ability, it also relies on the first waist-shaped hole 45a and the first adjusting screw at the horizontal plate 45, and the second waist-shaped hole 46a and the second adjusting screw at the positioning plate 46, to form an XY axis adjustment system, so as to ensure the plane position adjustment effect of the roller brush 41. Further, the Z-direction action adjustment effect of the two roller brushes 41 can be realized by relying on the upper slide block and the lower slide block, cooperating with the third waist-shaped hole 44a and the third adjusting screw at the plumb plate 44, and finally ensuring the flexibility of adjustment. Of course, for the Z-direction adjustment, it is actually to realize the position adjustment purpose of the slide block at the shaft end of the roller brush 41, that is, to use the plumb sliding action of the upper slide block and the lower slide block relative to the guide rail at the plumb plate 44 to cooperate with the fastening function of the third adjusting screw, so as to achieve the adjustment effect; such Z-direction adjustment is a conventional and mature adjustment mode, which will not be described here.

[0039] In order to further understand the present application, the actual working process of the present application is given as follows: Figure 1

[0040] S1. The felt part at the coating section 10 is wrapped with a clean white cloth and soaked with cleaning liquid, and the peristaltic pump 13 is automatically set to titrate cleaning liquid once every ten seconds;

[0041] S2. The felt part at the wiping section 20 is also wrapped with a white cloth; no cleaning liquid titration is required here;

[0042] S3. Start the hot air blower 32, and use the hot air drying section 30 to keep the surface of the aluminum wire a dry;

[0043] S4. Start the power motor 43 at the dust removal and dust collection section 40 to remove the residual aluminum powder on the surface, and the dust suction pipe sends the aluminum powder in the cleaning process to the external dust collection equipment to prevent the aluminum powder from being scattered in the air; the horn-shaped dust suction port 48 plays a role in collecting aluminum powder; the external dust collection equipment plays a role in storing aluminum powder; the cover box 47 keeps the aluminum wire a in a relatively closed space during the cleaning process, so that the aluminum powder will not be scattered into the air of the factory building. When the gas source is started, the airflow nozzle 41b can continuously ensure the high cleaning efficiency of the bristles 41a.

[0044] Of course, for those skilled in the art, the present application is not limited to the details of the above exemplary embodiments, but also includes the same or similar ways that can be realized in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description.

[0045] ​In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that those skilled in the art can understand.

[0046] The technical parts not described in detail in the utility model are well-known technologies.
