Description

Technical Field

[0001] This application relates to the technical field of aluminum processing, and particularly to a wire drawing device for color-coated aluminum coils. Background Art

[0002] Surface wire drawing treatment forms linear patterns on the workpiece surface by grinding the product. Usually, it is divided into straight wires and random wires according to different surface effects. When producing color-coated aluminum, in order to improve the surface texture of color-coated aluminum, wire drawing treatment is often carried out on color-coated aluminum. When performing wire drawing treatment on color-coated aluminum, sandpaper is repeatedly used to scrape lines on the aluminum. The main process of this technology is divided into three parts: degreasing, sanding machine, and water washing. The metal matte of the aluminum profile after the wire drawing process will show fine hair-like luster, improving the texture of the metal material, providing a good decorative effect for the aluminum profile to increase the aesthetic degree of the product. Wire drawing can also eliminate scratches, abrasions, processing tool marks, etc. on the aluminum profile.

[0003] In the existing aluminum coil wire drawing equipment, such as the Chinese patent with the publication number CN216802874U, it discloses a wire drawing treatment device for aluminum coil production. Specifically, it includes a device main body and a wire drawing mechanism installed at the upper end of the device main body. A fixing frame is installed at the upper end of the device main body. A support frame is installed inside the fixing frame through an adjustment structure. The fixing frames are symmetrically arranged at the upper end of the device main body. The lower end of the support frame is connected to a cleaning plate through an elastic member. The elastic member is a flexible rubber strip. The lower end of the cleaning plate is connected to a sponge block through a magic tape. The dust and ash on the aluminum surface can be cleaned by the sponge brush.

[0004] In the above-mentioned prior art, the wire drawing function of the aluminum coil can also be realized. However, on the one hand, when wire drawing the aluminum coil in the above-mentioned prior art, the metal debris and impurities generated during the wire drawing process cannot be removed in time, so that the debris and impurities may scratch the aluminum coil, affecting the wire drawing effect of the aluminum coil. On the other hand, when wire drawing the aluminum coil in the above-mentioned prior art, only the impurities on the aluminum coil can be cleaned, and the impurities on the wire drawing mechanism cannot be cleaned, affecting the subsequent wire drawing effect of the wire drawing mechanism on the aluminum coil. Based on this, there is still room for improvement in the existing aluminum coil wire drawing technology. Summary of the Invention

[0030] The following further elaborates on the present application in conjunction with the attached Figure 1-8 drawings.

[0031] The embodiments of the present application disclose a color-coated aluminum coil wire drawing device, which can realize the function of wire drawing the aluminum coil to increase the surface beauty of the aluminum coil.

[0032] Refer to Figure 1As shown, a color-coated aluminum coil wire drawing device disclosed in this embodiment includes: a base 1, which is a U-shaped structure; a fixed unit 2, which is symmetrically arranged on the inner wall of the base 1, and a cylindrical frame 3 is installed between the fixed units 2 arranged opposite to each other, and the cylindrical frame 3 is rotatably connected with the fixed unit 2 through a sealed bearing, and a sealed cavity is arranged between the inner side of the cylindrical frame 3 and the fixed unit 2; a rotating unit 4, which is symmetrically installed in the middle of the base 1, and the middle of the rotating unit 4 is arranged through the fixed unit 2 and the cylindrical frame 3, and the rotating unit 4 is used to drive the cylindrical frame 3 to rotate at a uniform speed; The wire drawing unit 5 is evenly arranged on the cylindrical frame 3. The wire drawing unit 5 cooperates with the fixing unit 2. The wire drawing unit 5 is used to perform wire drawing on the surface of the aluminum coil and remove impurities generated during the wire drawing process; the pressure roller 6 is evenly arranged on the lower end of the inner wall of the base 1. The pressure roller 6 is used to guide and support the aluminum coil; the cleaning unit 7 is arranged between the two cylindrical frames 3. The cleaning unit 7 is installed on the inner wall of the base 1. The cleaning unit 7 cooperates with the rotating unit 4. The cleaning unit 7 is used to clean and collect impurities on the wire drawing unit 5.

[0033] During actual use, the deesterified aluminum coil is transferred to the upper end of the clamping roller 6 and moves at a uniform speed. The rotating unit 4 drives the cylindrical frame 3 to rotate at a uniform speed. The wire drawing unit 5 rotates synchronously with the cylindrical frame 3. The fixed unit 2 ejects the wire drawing unit 5 that rotates to the bottom. The ejected wire drawing unit 5 is in close contact with the surface of the aluminum coil and performs wire drawing on the aluminum coil. After that, the ejected wire drawing unit 5 continues to rotate and retracts to its original position. The cleaning unit 7 brushes and cleans and collects the impurities generated on the surface of the wire drawing unit 5. After the wire drawing is completed, the aluminum coil enters the water washing process.

[0034] It should be noted that after two wire drawing processes, the aluminum coil can achieve the desired texture, which can also be divided into coarse wire drawing and fine wire drawing, completely eliminating the abrasions, scratches, processing knife marks, etc. on the surface of the aluminum coil, and increasing the aesthetics of the aluminum coil.

[0035] Reference Figure 6 As shown, the fixing unit 2 includes a fixing sleeve 21 and a cam 22. The fixing sleeve 21 is symmetrically mounted on the inner wall of the base 1, and the cam 22 is mounted inside the fixing sleeve 21, with the protruding end of the cam 22 facing downward.

[0036] During actual use, when the rotating unit 4 drives the cylindrical frame 3 to rotate at a constant speed, the wire drawing unit 5 rotates synchronously with the cylindrical frame 3. When the wire drawing unit 5 rotates to the lower end of the cylindrical frame 3, the cam 22 pushes the wire drawing unit 5 out of the cylindrical frame 3. The ejected wire drawing unit 5 is in close contact with the surface of the aluminum coil and performs wire drawing on the aluminum coil.

[0037] It should be noted that the cam 22 of a suitable size can be replaced according to the aluminum coils of different thicknesses, so that the ejected wire drawing unit 5 can perform wire drawing on the surface of the aluminum coil.

[0038] Refer to Figure 5 As shown, the rotating unit 4 includes a rotating rod 41, a driving motor 42 and a rotating disk 43. The middle part of the base 1 is installed with the rotating rod 41 through a bearing. The rotating rod 41 is located in the middle of the fixing unit 2 and the cylindrical frame 3. The middle part of the rotating rod 41 is connected to the cylindrical frame 3. The outside of the base 1 is installed with the driving motor 42 through a motor base. The output shaft of the driving motor 42 is connected to the rotating rod 41. The end of the rotating rod 41 passes through the base 1 and is installed with the rotating disk 43.

[0039] During actual use, the driving motor 42 drives the rotating rod 41 to rotate at a constant speed. The rotating disk 43 and the cylindrical frame 3 rotate synchronously with the rotating rod 41. The rotating disk 43 drives the cleaning unit 7 to reciprocate, so that the cleaning unit 7 can brush and clean the debris and impurities on the surface of the wire drawing unit 5, preventing the debris and impurities on the surface of the wire drawing unit 5 from scratching the aluminum coil during wire drawing of the aluminum coil, etc., and affecting the wire drawing effect of the aluminum coil.

[0040] It should be noted that the driving motor 42 located on the left side of the base 1 rotates clockwise, the driving motor 42 located on the right side of the base 1 rotates counterclockwise, and the rotation speed of the cylindrical frame 3 is not equal to the moving speed of the aluminum coil. A relative displacement can occur between the wire drawing unit 5 and the aluminum coil, so that the wire drawing unit 5 can perform wire drawing treatment on the aluminum coil.

[0041] Refer to Figure 7 As shown, an annular groove is provided on the inner side surface of the rotating disk 43. Raised blocks 431 are evenly installed in the annular groove. The outer side surface of the raised block 431 is a smooth structure.

[0042] During actual use, a wavy track is formed between the raised block 431 and the annular groove. The cleaning unit 7 can reciprocate along the wavy track, so that the cleaning unit 7 can brush and clean the surface of the wire drawing unit 5 when reciprocating.

[0043] Refer to Figure 6 and Figure 8 As shown, the wire drawing unit 5 includes a U-shaped frame 51, a top rod 52, a reset assembly 53, a pressing assembly 54, a sandpaper 55 and a ventilation frame 56. T-shaped grooves are evenly provided on the cylindrical frame 3. The U-shaped frame 51 is slidably provided in the T-shaped grooves. The two ends of the U-shaped frame 51 are symmetrically provided with top rods 52. The end of the top rod 52 is an arc structure. The top rod 52 cooperates with the fixing unit 2. Rectangular grooves are symmetrically provided on both sides of the T-shaped grooves. The reset assembly 53 is installed in the rectangular grooves. The pressing assemblies 54 are evenly installed on the U-shaped frame 51. The sandpaper 55 is installed on the outside of the U-shaped frame 51 through the pressing assemblies 54. A sealing groove is provided on the inner side of the U-shaped frame 51. The ventilation frame 56 is provided in the sealing groove. The ventilation frame 56 is hermetically connected to the sealing groove. The ventilation frame 56 is provided with ventilation holes communicating with the sealing cavity.

[0044] During actual use, when the U-shaped frame 51 rotates under the cylinder frame 3, the ejector rod 52 on the U-shaped frame 51 is in close contact with the cam 22. Under the action of the cam 22, the ejector rod 52 drives the U-shaped frame 51 to eject from the cylinder frame 3. The sandpaper 55 moves synchronously with the U-shaped frame 51, and the ejected sandpaper 55 performs wire drawing on the aluminum coil below; when the U-shaped frame 51 continues to rotate, the ejector rod 52 gradually separates from the cam 22, and the reset assembly 53 drives the U-shaped frame 51 to retract into the cylinder frame 3, and the sandpaper 55 separates from the aluminum coil. Scratches and abrasions on the surface of the aluminum coil after wire drawing are completely eliminated, increasing the aesthetics of the aluminum coil.

[0045] Refer to Figure 8 As shown, the reset assembly 53 includes a compression spring 531 and a pressing plate 532. The compression spring 531 is installed in the rectangular groove, and the pressing plate 532 is installed outside the compression spring 531. The pressing plate 532 is in close contact with the U-shaped frame 51.

[0046] During actual use, when the ejector rod 52 drives the U-shaped frame 51 to eject from the cylinder frame 3 under the action of the cam 22, the U-shaped frame 51 drives the pressing plate 532 to move outward from the cylinder frame 3. At this time, the compression spring 531 is gradually compressed; when the ejector rod 52 gradually separates from the cam 22, the compression spring 531 drives the U-shaped frame 51 to reset through the pressing plate 532, and the sandpaper 55 separates from the aluminum coil.

[0047] Refer to Figure 8 As shown, the outer side of the U-shaped frame 51 is an arc structure, and air blowing holes are uniformly arranged on the U-shaped frame 51. The air blowing holes and the pressing assembly 54 are arranged at intervals.

[0048] During actual use, an air inlet pipe is provided on the fixed sleeve 21, and the air inlet pipe is connected to an air pump. Air flows into the sealing cavity through the air inlet pipe. When the U-shaped frame 51 is in close contact with the ventilation frame 56, the sealing groove is not connected to the sealing cavity; when the ejector rod 52 drives the U-shaped frame 51 to eject from the cylinder frame 3 under the action of the cam 22, the sealing groove is connected to the sealing cavity through the ventilation holes on the ventilation frame 56, and the air blowing holes on the U-shaped frame 51 are connected to the sealing groove. The air blown out of the air blowing holes can blow off the debris and impurities generated on the aluminum coil, preventing the debris and impurities from affecting the wire drawing process, and being beneficial to improving the wire drawing effect of the aluminum coil.

[0049] Refer to Figure 8 As shown, the pressing assembly 54 includes a pressing piece 541 and a locking bolt 542. The pressing pieces 541 are uniformly arranged on the U-shaped frame 51. The pressing pieces 541 are tightened on the U-shaped frame 51 through the locking bolts 542, and the sandpaper 55 is pressed between the pressing pieces 541.

[0050] During actual use, the pressing piece 541 can be installed on the U-shaped frame 51 by tightening the locking bolt 542, and the pressing piece 541 can fix the sandpaper 55 on the arc-shaped structure outside the U-shaped frame 51.

[0051] It should be noted that a new sandpaper 55 can be replaced according to the wear condition of the sandpaper 55. Replacing the sandpaper 55 through the pressing piece 541 and the locking bolt 542 is convenient and fast, improving work efficiency.

[0052] Refer to Figure 3 and Figure 5 As shown, the cleaning unit 7 includes a trapezoidal frame 71, a fixed rod 72, an arc-shaped plate 73, a return spring 74, a linear bearing 75, a moving rod 76, and a brush 77. A trapezoidal frame 71 is installed in the middle of the base 1. An installation groove is provided in the middle of the trapezoidal frame 71, and a collection groove is provided at the lower end of the installation groove. Fixed rods 72 are symmetrically installed in the installation groove. An arc-shaped plate 73 is slidably arranged on the fixed rods 72. A return spring 74 is installed at the end of the fixed rod 72. Brush hairs 77 are evenly arranged on the outer side surface of the arc-shaped plate 73. A moving rod 76 is installed on the base 1 through a linear bearing 75. The inner side of the moving rod 76 is connected to the arc-shaped plate 73. The outer end of the moving rod 76 is a smooth structure, and the outer end of the moving rod 76 is matched with the rotating disk 43.

[0053] During actual use, when the rotating disk 43 rotates at a constant speed, the arc-shaped plate 73 makes a reciprocating motion under the action of the raised block 431 and the return spring 74. When the brush hairs 77 follow the arc-shaped plate 73 to make a reciprocating motion, impurities on the sandpaper 55 are cleaned. The debris and impurities brushed off by the brush hairs 77 fall into the collection groove. The brush hairs 77 can remove the debris and impurities on the surface of the sandpaper 55, prevent the debris and impurities from affecting the wire drawing effect, and improve the aesthetics after the aluminum coil wire drawing is completed.

[0054] The implementation principle of this embodiment is as follows:

[0055] 1: Rotating and ejecting. The driving motor 42 drives the rotating rod 41 to rotate at a constant speed. The wire drawing unit 5 rotates synchronously with the rotating rod 41 through the cylindrical frame 3. When the wire drawing unit 5 rotates to the lower end of the cylindrical frame 3, the cam 22 ejects the U-shaped frame 51 out of the cylindrical frame 3 through the ejector rod 52.

[0056] 2: Wire drawing and retracting. The sandpaper 55 moves synchronously with the U-shaped frame 51. The sandpaper 55 performs wire drawing treatment on the surface of the aluminum coil. The U-shaped frame 51 blows out air to remove the generated debris and impurities. Then, the reset assembly 53 drives the U-shaped frame 51 to reset.

[0057] 3: Clean the debris. Rotate the rotating disk 43 at a constant speed. The arc-shaped plate 73 reciprocates under the action of the raised block 431 and the return spring 74. When the brush bristles 77 reciprocate with the arc-shaped plate 73, they clean the impurities on the sandpaper 55.
