Description

Technical Field

[0001] This utility model relates to the field of aluminum profile polishing technology, specifically to a polishing device for aluminum profiles. Background Technology

[0002] During the production of aluminum profiles, polishing is typically performed to improve surface quality and lay a good foundation for subsequent surface treatment processes such as spraying. Currently, for polishing long, narrow aluminum profiles, the industry generally uses vertical polishing equipment. This type of equipment usually consists of a lifting support and a pair of vertically movable polishing units. These polishing units are mounted on the lifting support via a drive assembly to perform the polishing operation on the long, narrow aluminum profile. However, in existing vertical polishing equipment, the motor in the drive assembly is usually mounted at the top of the lifting support, which also needs to suspend the long, narrow aluminum profile to be polished. This design causes the weight of the motor and the aluminum profile to be polished to act simultaneously on the top of the lifting support, placing significant pressure on it. Over long-term use, this pressure may cause deformation, wear, or even damage to the top structure of the lifting support, thus affecting the stability and service life of the polishing equipment.

Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] A polishing device for aluminum profiles includes a lifting bracket 1, a driving mechanism 2, and several pairs of polishing units 3. The driving mechanism 2 includes a first driver 21 and a sprocket and chain assembly 22.

[0034] The first driver 21 is disposed at the bottom of the lifting bracket 1, and the sprocket and chain assembly 22 is disposed on the lifting bracket 1. The first driver 21 is used to drive the sprocket and chain assembly 22 to operate. Each pair of polishing units 3 is disposed on the lifting bracket 1 in a way that allows them to move up and down through the sprocket and chain assembly 22. Several pairs of polishing units 3 are evenly spaced along the vertical direction, and two polishing units 3 in each pair are symmetrically distributed from left to right.

[0035] This solution provides a polishing device for aluminum profiles. In this embodiment, for example... Figure 1 and Figure 3 As shown, the first driver 21 is a motor, and the lifting bracket 1 is equipped with three pairs of polishing units 3. When polishing a long strip of aluminum profile is required, the operator first suspends the long strip of aluminum profile 5 to be polished on the transport component 4 near the top of the lifting bracket 1. The transport component 4 is an existing structure used to transport and suspend the long strip of aluminum profile 5. The suspended long strip of aluminum profile 5 to be polished is located between each pair of polishing units 3, so that each pair of polishing units 3 can polish the left and right sides of the long strip of aluminum profile 5. Next, the first driver 21 is started, which drives the sprocket and chain assembly 22 to operate. Since each pair of polishing units 3 is movably mounted on the lifting bracket 1 via the sprocket and chain assembly 22, the operation of the sprocket and chain assembly 22 can drive each pair of polishing units 3 to move up and down, thereby realizing the height adjustment of each pair of polishing units 3 and thus realizing the polishing operation of the long strip of aluminum profile. Since several pairs of polishing units 3 are evenly spaced along the vertical direction, each pair of polishing units 3 can simultaneously polish the long strip aluminum profile 5 to be polished within their respective different height ranges, which is beneficial to improving the polishing efficiency of the entire long strip aluminum profile.

[0036] In this solution, by placing the first driver 21 at the bottom of the lifting bracket 1, compared to the traditional method of mounting the motor at the top of the lifting bracket, the pressure on the top of the lifting bracket 1 can be effectively reduced, thereby preventing deformation, wear or even damage to the top structure of the lifting bracket 1, and thus improving the service life of the entire polishing device.

[0037] Preferably, the polishing unit 3 includes a support base 31, and the sprocket and chain assembly 22 includes two first sprockets 221, two second sprockets 222, two third sprockets 223, two fourth sprockets 224, two fifth sprockets 225, two sixth sprockets 226, two first chains 227, two first shafts 228, and two second shafts 229;

[0038] The left side of the lifting bracket 1 is provided with two first sprockets 221, two second sprockets 222, two sixth sprockets 226, and two first rotating shafts 228. The right side of the lifting bracket 1 is provided with two third sprockets 223, two fourth sprockets 224, two fifth sprockets 225, and two second rotating shafts 229. The two first sprockets 221, two fourth sprockets 224, one first rotating shaft 226, and one second rotating shaft 229 are all located at the bottom of the lifting bracket 1. The two second sprockets 222, two third sprockets 223, two fifth sprockets 225, and two sixth sprockets 226 are all located at the bottom of the lifting bracket 1. The sixth sprocket 226, another first rotating shaft 228, and another second rotating shaft 229 are all located at the top of the lifting bracket 1; the two first sprockets 221 are symmetrically distributed front to back and are each mounted on one of the first rotating shafts 228; the two second sprockets 222 are symmetrically distributed front to back and are each mounted on the other first rotating shaft 228; the two third sprockets 223 are symmetrically distributed front to back and are each mounted on one of the second rotating shafts 229; the two fourth sprockets 224 are symmetrically distributed front to back and are each mounted on the other second rotating shaft 229; the two fifth sprockets 225 are symmetrically distributed front to back; and the two sixth sprockets 226 are symmetrically distributed front to back.

[0039] The driving end of the first driver 21 is connected to the rear end of the second rotating shaft 229 located at the bottom of the lifting bracket 1. One end of the first chain 227 is connected to the fourth sprocket 224 located at the rear, and the other end passes sequentially around the third sprocket 223, the second sprocket 222, the first sprocket 221, the sixth sprocket 226, and the fifth sprocket 225 located at the rear, and is connected to the fourth sprocket 224 located at the rear. One end of the other first chain 227 is connected to the fourth sprocket 224 located at the front, and the other end passes sequentially around the third sprocket 223, the second sprocket 222, the first sprocket 221, the sixth sprocket 226, and the fifth sprocket 225 located at the front, and is connected to the fourth sprocket 224 located at the front.

[0040] The support base 31 is movably mounted on the lifting bracket 1, and the support base 31 is connected to the two first chains 227.

[0041] In this embodiment, as Figure 2-4 As shown, when the polishing unit 3 needs to move up and down, the first driver 21 is activated. The first driver 21 drives the fourth sprocket 224 located at the rear to rotate. The fourth sprocket 224 located at the rear drives the first chain 227 connected to it to drive the transmission. The fourth sprocket 224 located at the front rotates, thereby driving the first chain 227 connected to the fourth sprocket 224 located at the front to drive the transmission. This drives the two third sprockets 223, the two second sprockets 222, the two first sprockets 221, the two sixth sprockets 226, and the two fifth sprockets 225 to rotate, thereby realizing the operation of the entire sprocket and chain assembly 22. Since the support base 31 is movably mounted on the lifting bracket 1, and the support base 31 is connected to the two first chains 227, the transmission of the two first chains 227 can drive the support base 31 to move up and down, thereby driving the entire polishing unit 3 to move up and down.

[0042] Preferably, it also includes a counterweight assembly 6, which includes two first fixed sprockets 61, two second fixed sprockets 62, two second chains 63, two third chains 64, two first weights 65 and two second weights 66;

[0043] Two first fixed sprockets 61 are installed on the left side of the top of the lifting bracket 1, and the two first fixed sprockets 61 are symmetrically distributed front and back; two second fixed sprockets 62 are installed on the right side of the top of the lifting bracket 1, and the two second fixed sprockets 62 are symmetrically distributed front and back; one end of each of the two second chains 63 is connected to the support base 31 located on the left side of the lifting bracket 1, and the other end of each of the two second chains 63 passes around the corresponding first fixed sprocket 61 and is connected to the corresponding first counterweight 65; one end of each of the two third chains 64 is connected to the support base 31 located on the right side of the lifting bracket 1, and the other end of each of the two third chains 64 passes around the corresponding second fixed sprocket 62 and is connected to the corresponding second counterweight 66.

[0044] In this embodiment, as Figure 2 As shown, the counterweight assembly 6 ensures more stable up-and-down movement of the polishing unit 3. Further explanation: since both first fixed sprockets 61 are installed on the left side of the top of the lifting bracket 1 and are symmetrically distributed front-to-back; and both second fixed sprockets 62 are installed on the right side of the top of the lifting bracket 1 and are symmetrically distributed front-to-back, this ensures the balance and stability of the entire counterweight assembly 6.

[0045] Preferably, the polishing unit 3 further includes a plurality of guide wheels 30, and two guide rails 10 are provided on both the left and right sides of the lifting bracket 1; the two guide rails 10 on the left side of the lifting bracket 1 are symmetrically distributed front and back, and the two guide rails 10 on the right side of the lifting bracket 1 are symmetrically distributed front and back, and all four guide rails 10 are arranged in the up and down direction. A plurality of guide wheels 30 are provided on both the front and back sides of the support base 31, and the wheel surfaces of the plurality of guide wheels 30 respectively abut against the corresponding guide rails 10.

[0046] In this embodiment, as Figure 5 As shown, since the surfaces of several guide wheels 30 abut against the corresponding guide rails 10, the cooperation between the guide wheels 30 and the guide rails 10 makes the up-and-down movement of the polishing unit 3 more stable.

[0047] Preferably, the polishing unit 3 further includes a front-to-back translation component 32, a left-to-right translation component 33, a mounting base 34, a mounting frame 35, a polishing roller 36, and a second driver 37; the front-to-back translation component 32 is disposed on the support base 31, the mounting base 34 is disposed on the front-to-back translation component 32, the left-to-right translation component 33 is disposed on the mounting base 34, the mounting frame 35 is disposed on the left-to-right translation component 33, the polishing roller 36 is rotatably mounted on the mounting frame 35, the second driver 37 is mounted on the mounting frame 35, and the driving end of the second driver 37 is connected to one end of the polishing roller 36; the front-to-back translation component 32 is used to move the mounting frame 35 back and forth, and the left-to-right translation component 33 is used to move the mounting frame 35 left and right.

[0048] Specifically, such as Figure 6 As shown, the forward and backward translation component 32 enables the mounting frame 35 to move forward and backward, thereby realizing the forward and backward movement of the grinding roller 36. The left and right translation component 33 enables the mounting frame 35 to move left and right, thereby realizing the left and right movement of the grinding roller 36. Since the driving end of the second driver 37 is connected to one end of the grinding roller 36, by activating the second driver 37 (in this embodiment, the second driver 37 is a motor), the second driver 37 can drive the grinding roller 36 to rotate, thereby realizing the polishing treatment of the surface of the elongated aluminum profile 5 to be polished. The mounting base 34 makes the installation of the left and right translation component 33 more stable. The mounting frame 35 provides support for the second driver 37 and the grinding roller 36. Further, the grinding roller 36 can move freely in the forward, backward, left and right, and up and down directions. This multi-directional movement allows the grinding roller 36 to flexibly contact and polish all surfaces of the elongated aluminum profile 5 to be polished.

[0049] Preferably, the forward and backward translation component 32 includes two first slide rails 321, four first sliders 322, and a first lead screw stepper motor 323. The first lead screw stepper motor 323 includes a first screw block 3231 and a first lead screw 3232. The first screw block 3231 is threadedly connected to the first lead screw 3232, and the first lead screw 3232 is arranged in the forward and backward direction. The two first slide rails 321 and the first lead screw stepper motor 323 are all mounted on the support base 31. The two first slide rails 321 are symmetrically distributed from left to right and are arranged in the forward and backward direction. Two first sliders 322 are slidably mounted on each of the two first slide rails 321. The mounting base 34 is mounted on the top of the four first sliders 322 and the first screw block 3231.

[0050] In this embodiment, as Figure 7As shown, since the mounting base 34 is mounted on the top of the four first sliders 322 and the first screw block 3231, by starting the first lead screw stepper motor 323, the first screw block 3231 can reciprocate back and forth along the first lead screw 3232, thereby driving the mounting base 34 to move back and forth, thereby realizing the back and forth movement of the grinding roller 36.

[0051] Preferably, the left-right translation component 33 includes two second slide rails 331, four second sliders 332, and a second lead screw stepper motor 333. The second lead screw stepper motor 333 includes a second screw block 3331 and a second lead screw 3332. The second screw block 3331 and the second lead screw 3332 are threadedly connected, and the second lead screw 3332 is arranged in the left-right direction. The two second slide rails 331 and the second lead screw stepper motor 333 are all mounted on the mounting base 34. The two second slide rails 331 are symmetrically distributed front and back, and both second slide rails 331 are arranged in the left-right direction. Two second sliders 332 are slidably mounted on each of the two second slide rails 331. The mounting bracket 35 is mounted on the top of the four second sliders 332 and the second screw block 3331.

[0052] In this embodiment, as Figure 8 As shown, since the mounting bracket 35 is mounted on the top of the four second sliders 332 and the second screw block 3331, by starting the second lead screw stepper motor 333, the second screw block 3331 can reciprocate left and right along the second lead screw 3332, thereby driving the mounting bracket 35 to move left and right, thereby realizing the left and right movement of the grinding roller 36.

[0053] Preferably, the polishing unit 3 further includes a baffle assembly 38, which includes a support frame 381, a triangular plate 382, ​​and a baffle 383. The bottom of the support frame 381 is mounted on the support base 31, the baffle 383 is obliquely fixed to the top of the support frame 381, the triangular plate 382 is fixed between the baffle 383 and the support frame 381, and the baffle 383 is located above the polishing roller 36.

[0054] In this embodiment, as Figure 6As shown, the support frame 381 provides support for the baffle 383. Since the baffle 383 is tilted and fixed to the top of the support frame 381 and located above the grinding roller 36, it effectively blocks the scraps generated during the polishing process of the long aluminum profile, preventing these scraps from scattering. Because the triangular plate 382 is fixed between the baffle 383 and the support frame 381, the triangular plate 382 enhances the stability of the entire baffle assembly 38 structure, preventing the baffle 383 from deforming or collapsing under stress.

[0055] Preferably, the polishing unit 3 further includes a support rod 39 and a receiving tray 310. The support rod 39 is installed on the left side of the mounting frame 35, and the receiving tray 310 is fixed to the support rod 39. The receiving tray 310 is located below the polishing roller 36. In this embodiment, as... Figure 6 As shown, the receiving tray 310 effectively catches and collects the scraps generated during the polishing process of the long aluminum profile 5. This not only prevents the scraps from scattering into the work area, thus maintaining a clean and orderly work area, but also facilitates the recycling and processing of the collected scraps. The support rod 39 makes the installation of the receiving tray 310 more stable.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way.
