Abstract
Description
Technical Field
[0001] This application relates to the field of aluminum strip processing technology, for example to a pressing device for an aluminum strip uncoiler. Background Technology
[0002] Currently, when processing aluminum coils, uncoiling is necessary to facilitate subsequent processing operations such as cutting and stamping. Aluminum coil uncoilers, as uncoiling equipment for sheet metal coils, typically use a motor-driven system to rotate rollers around a shaft holding the sheet metal coil, thus achieving uncoiling. When the uncoiling speed of the uncoiler is too high, the aluminum strip is prone to vibration and swaying, causing feed deviations when the aluminum strip enters the leveling mechanism, affecting processing quality.
[0003] An existing uncoiler includes a machine base, a rotating roller shaft, and a pressure arm. The rotating roller shaft is rotatably mounted on the machine base and is used to hold and mount aluminum coils. One end of the pressure arm is rotatably mounted on the machine base, and the other end has a pressure roller for pressing and limiting the aluminum coil. By pressing and limiting the rotating aluminum coil with the pressure arm, the risk of vibration and swaying of the aluminum strip is reduced, the feed deviation when the aluminum strip enters the leveling mechanism is minimized, and the processing quality is improved.
[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:
[0005] The pressure arm can only press aluminum coils with a relatively small diameter range, making it difficult to meet different processing needs.
[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.
[0008] This disclosure provides a pressing device for an aluminum strip uncoiler, which adjusts the distance between the rotating arm and the placement part according to the size of the aluminum coil, adapting to aluminum coils of different sizes to meet different processing requirements.
[0009] In some embodiments, the pressing device of the aluminum strip uncoiler includes: a base, a sliding assembly, and a rotating arm. The base is provided with a placement section for mounting aluminum coils; the sliding assembly is slidably connected to the base to adjust the distance between the sliding assembly and the placement section; one end of the rotating arm is rotatably connected to the sliding assembly, and the other end is rotatably equipped with a pressing wheel.
[0010] Optionally, the sliding assembly includes: a connecting seat, a sliding rod, a sliding plate, and a plug-in rod. The connecting seat is disposed on one side of the machine base and is rotatably connected to one end of the rotating arm; the sliding rod is fixedly connected to the top of the connecting seat and slidably connected to the machine base; the sliding plate is fixedly connected to the bottom of the connecting seat and slidably connected to the machine base, and the sliding plate is provided with a plug-in hole; the plug-in rod passes through the plug-in hole and plugs into one of the multiple plug-in slots on the machine base.
[0011] Optionally, a sliding seat is slidably provided on the connecting seat, one end of the rotating arm is slidably connected to the rotating shaft, and the rotating shaft is rotatably connected to the sliding seat.
[0012] Optionally, the end of the rotating arm is provided with a limiting hole, and the rotating shaft is provided with multiple limiting grooves, with the limiting rod passing through and being inserted into one of the limiting grooves.
[0013] Optionally, a hydraulic cylinder is provided on the lower side of the sliding seat, the hydraulic cylinder is connected to the connecting seat, and the output end of the hydraulic cylinder is connected to the sliding seat.

[0016] Optionally, there are two pressure rollers located on opposite sides of the rotating arm.
[0017] The pressing device for the aluminum strip uncoiler provided in this embodiment can achieve the following technical effects:
[0018] When placing and mounting aluminum coils in the placement section, a sliding assembly is slidable relative to the base. Adjusting the distance between the sliding assembly and the placement section causes the sliding assembly to move the rotating arm, thus adjusting the distance between the rotating arm and the placement section accordingly.

The wide range of adaptability caters to diverse processing needs.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0033] Combination Figure 1-4 As shown in the figure, this disclosure provides a pressing device for an aluminum strip uncoiler, including: a base 100, a sliding assembly 200, and a rotating arm 300. The base 100 is provided with a placement part 110 for mounting aluminum coils; the sliding assembly 200 is slidably connected to the base 100 to adjust the distance between the sliding assembly 200 and the placement part 110; one end of the rotating arm 300 is rotatably connected to the sliding assembly 200, and the other end is rotatably provided with a pressing wheel 400.
[0034] Using the pressing device of the aluminum strip uncoiler provided in this embodiment, when the aluminum coil is placed and installed in the placement part 110, the sliding component 200 is slidably slid relative to the machine base 100. The distance between the sliding component 200 and the placement part 110 is adjusted, and the sliding component 200 drives the rotating arm 300 to move, thereby correspondingly adjusting the distance between the rotating arm 300 and the placement part 110. Thus, the distance between the rotating arm 300 and the placement part 110 is adjusted according to the size of the aluminum coil, adapting to aluminum coils of different sizes, providing a relatively wide range of adaptability to meet different processing requirements.
[0035] Understandably, when the aluminum coil is mounted on the placement part 110, the rotating arm 300 rotates relative to the sliding assembly 200, and the pressure roller 400 on the rotating arm 300 then abuts against and presses against the aluminum coil. During the uncoiling and rotation of the aluminum coil, the pressure roller 400 rotates along with it, reducing the risk of the aluminum coil shaking and vibration.
[0036] Optionally, the rotating arm 300 is an arc-shaped rod structure. In this way, the rotating arm 300 is arc-shaped and curved, and the aluminum coil is circular, corresponding to the shape of the aluminum coil, reducing the risk of interference between the rotating arm 300 and the aluminum coil.
[0037] Optionally, the sliding assembly 200 includes: a connecting seat 210, a sliding rod 220, a sliding plate 230, and a plug-in rod 240. The connecting seat 210 is disposed on one side of the base 100 and is rotatably connected to one end of the rotating arm 300; the sliding rod 220 is fixedly connected to the top of the connecting seat 210 and slidably connected to the base 100; the sliding plate 230 is fixedly connected to the bottom of the connecting seat 210 and slidably connected to the base 100, and the sliding plate 230 is provided with a plug-in hole 231; the plug-in rod 240 passes through the plug-in hole 231 and plugs into one of the plurality of plug-in slots 120 on the base 100. In this way, by pulling the plug-in rod 240 out of its plug-in slot 120, the restriction on the sliding plate 230 is released. The sliding plate 230, the connecting seat 210, and the sliding rod 220 can slide relative to the base 100, adjusting the distance between the connecting seat 210 and the base 100, and driving the rotating arm 300 to move, adjusting the distance between the rotating arm 300 and the placement part 110 to adapt to aluminum coils of different sizes. After the connecting seat 210 is adjusted to the correct position, the plug-in rod 240 is inserted into a corresponding plug-in slot 120, thereby restricting the sliding plate 230, the connecting seat 210, and the sliding rod 220 from sliding relative to the base 100.
[0038] Specifically, there are four insertion slots 120. In this way, the number of insertion slots 120 is relatively large, and the connector 210 can be adjusted to a relatively large number of positions with relatively high adjustment precision.
[0039] Specifically, the insertion hole 231 is semi-circular.
[0040] Optionally, the top of the base 100 is provided with a sliding groove, and the sliding rod 220 is slidably connected to the sliding groove. In this way, the sliding groove provides guidance and limit for the sliding of the sliding rod 220, reducing the risk of the sliding rod 220 deviating, and thus reducing the risk of the connecting seat 210 and the sliding plate 230 deviating.
[0041] Optionally, the lower side wall and one side wall of the sliding plate 230 abut against the base 100. In this way, the sliding plate 230 slides against the base 100, which provides relatively high stability. The base 100 can also provide guidance and limit for the sliding plate 230, reducing the risk of the sliding plate 230 deviating during the sliding process.
[0042] Optionally, a sliding seat 250 is slidably provided on the connecting seat 210, and one end of the rotating arm 300 is slidably connected to the rotating shaft 310, with the rotating shaft 310 rotatably connected to the sliding seat 250. In this way, the sliding seat 250 can slide relative to the connecting seat 210, adjusting the height of the sliding seat 250 relative to the placement portion 110, and consequently adjusting the heights of the rotating shaft 310 and the rotating arm 300 relative to the placement portion 110, to accommodate aluminum coils of different sizes. This provides a relatively wide range of adaptability and better meets different processing requirements. Furthermore, the rotating arm 300 can slide relative to the rotating shaft 310, adjusting its position relative to the machine base 100, and consequently adjusting its position relative to the aluminum coil, thus accommodating aluminum coils of different widths. For example, when the aluminum coil is narrow, the rotating arm 300 is adjusted to a position relatively close to the sliding seat 250; when the aluminum coil is wide, the rotating arm 300 is adjusted to a position relatively far from the sliding seat 250.
[0043] Specifically, the two opposite sides of the connecting seat 210 protrude from the surface of the base 100, and the sliding seat 250 is sleeved on the opposite two sides of the connecting seat 210 and slidably connected to it. In this way, the connection strength between the sliding seat 250 and the connecting seat 210 is relatively high, the sliding stability is relatively good, and the risk of the sliding seat 250 shifting during the sliding process is reduced.
[0044] Optionally, a protrusion 311 is provided on the outer wall of the rotating shaft 310. The protrusion 311 is slidably connected to one end of the rotating arm 300, and the protrusion 311 restricts the relative rotation of the rotating shaft 310 and the rotating arm 300. In this way, since the pressure roller 400 on the rotating arm 300 abuts against and presses against the aluminum coil during the uncoiling and rotation process of the aluminum coil, the protrusion 311 restricts the relative rotation of the rotating arm 300 and the rotating shaft 310, reducing the risk of the rotating arm 300 rotating away from the aluminum coil and reducing the risk of the pressure roller 400 separating from the aluminum coil.
[0045] Optionally, the end of the rotating arm 300 is provided with a limiting hole 301, and the rotating shaft 310 is provided with multiple limiting grooves 312. A limiting rod 313 passes through the limiting rod 313 and is inserted into one of the limiting grooves 312. In this way, the limiting rod 313 passes through the limiting rod 313 and is inserted into one of the limiting grooves 312, thereby restricting the sliding of the rotating arm 300 relative to the rotating shaft 310 and reducing the risk of the pressure roller 400 running off-center during the uncoiling and rotation of the aluminum coil.
[0046] Specifically, there are eleven limiting slots 312. This results in a relatively large number of positions for the limiting slots 312, a relatively large number of positions for the limiting rods 313 to be inserted, and relatively high precision in adjusting the position of the rotating arm 300.
[0047] Optionally, a rotating shaft 310 can be slidably connected to multiple rotating arms 300. In this way, when the aluminum strip is wide, a single rotating arm 300 and its end pressure roller 400 can only press a relatively narrow width. By having multiple rotating arms 300 and multiple pressure rollers 400 working together, a relatively larger effective pressing width can be achieved, reducing the risk of aluminum coil swaying and vibration. Furthermore, each rotating arm 300 can slide independently relative to the rotating shaft 310, allowing for more flexible adjustment.
[0048] Specifically, there are two rotating arms 300, and each rotating arm 300 is slidably connected to the rotating shaft 310. In this way, through the cooperation of the two rotating arms 300 and the corresponding pressure rollers 400, the effective width of the aluminum strip can be pressed relatively large, reducing the risk of aluminum coil swaying and vibration.
[0049] Specifically, each rotating arm 300 is provided with a limiting hole 301.
[0050] Optionally, a motor 320 is provided on the sliding seat 250, and the output end of the motor 320 is connected to the rotating shaft 310. In this way, the motor 320 provides power for the rotation of the rotating shaft 310.
[0051] Optionally, a hydraulic cylinder 260 is provided on the lower side of the sliding seat 250. The hydraulic cylinder 260 is connected to the connecting seat 210, and the output end of the hydraulic cylinder 260 is connected to the sliding seat 250. In this way, the hydraulic cylinder 260 provides power for the sliding seat 250 to slide on the connecting seat 210, thereby adjusting the height of the sliding seat 250, the rotating arm 300, and the pressure roller 400 relative to the placement part 110 more quickly.
[0052] Optionally, a stop bar 330 is rotatably provided at the end of the rotating shaft 310 facing away from the sliding seat 250. In this way, when an aluminum coil is mounted on the placement part 110, the stop bar 330 can rotate to one side of the aluminum coil to block it and reduce the risk of the aluminum coil detaching from the placement part 110.
[0053] Optionally, a limiting plate 340 is fixedly provided at one end of the rotating shaft 310 facing away from the sliding seat 250. When the stop rod 330 rotates to the first position, the limiting plate 340 provides limiting support for the stop rod 330. In this way, by providing support for the stop rod 330 through the limiting plate 340, the end of the stop rod 330 facing away from the rotating shaft 310 extends towards the placement part 110 to cover the aluminum coil and reduce the risk of the aluminum coil detaching from the placement part 110.
[0054] Understandably, when the stop lever 330 is rotated to the first position, it means that the stop lever 330 is rotated to a horizontal position and the end of the baffle facing away from the rotating shaft 310 extends toward the placement part 110.
[0055] Optionally, the limiting plate 340 is fixedly connected to the connecting ring 350, and the connecting ring 350 is fixedly connected to the rotating shaft 310. In this way, the contact area between the connecting ring 350 and the rotating shaft 310 is relatively large, the stability of the connection is relatively high, thereby increasing the strength of the limiting plate 340 in supporting the baffle.
[0056] Optionally, two pressure rollers 400 are provided, located on opposite sides of the rotating arm 300. In this way, two pressure rollers 400 are provided on one rotating arm 300, the number of pressure rollers 400 is relatively large, there are relatively many points of contact with the aluminum coil, and the stability is relatively high.
[0057] Specifically, when there are two rotating arms 300, each rotating arm 300 is equipped with two pressure rollers 400.
[0058] Optionally, the pressure roller 400 is made of rubber. In this way, the pressure roller 400 has relatively good wear resistance.
[0059] Optionally, the placement part 110 is rotatably mounted on the base 100 around the rotating shaft 111. In this way, the aluminum coil is placed and mounted on the winding shaft, resulting in a relatively large contact area and higher stability.
