Description

Technical Field

[0001] The invention relates to the technical field of aluminum coil uncoilers, in particular to an uncoiler suitable for color-coated aluminum coils of various sizes. Background Art

[0002] An aluminum coil decoiler, also known as an aluminum coil unwinder or aluminum coil unwinder, is a mechanical device used to unwind aluminum coils (such as aluminum foil and aluminum sheet). It is widely used in industries such as metal processing and packaging manufacturing. Its primary function is to smoothly unwind the coiled aluminum material and feed it into subsequent processing equipment, such as shears and stamping machines, for further processing.

[0003] For related technology, please refer to the patent application with announcement number CN220825325U, which discloses an aluminum coil uncoiler, comprising a chassis, a motor fixedly mounted on the top outer wall of the chassis, a belt fixedly mounted on the outer edge of the motor's power output shaft, a gear fixedly connected to one end of the drive shaft, a turntable threadedly connected to the other end of the drive shaft, a collar rotatably sleeved on the outer wall of the drive shaft, a disc fixedly connected to the outer wall of the collar, a main shaft fixedly sleeved on the outer wall of the drive shaft, a threaded groove formed on the outer wall of the drive shaft, an annular buckle movably sleeved on the outer edge of the main shaft, and a winding tube provided on the outer edge of the square plate. By providing a winding tube on the main shaft, this application enables the rapid replacement of aluminum coils with different inner diameters, protects the edges of the aluminum coil, and reduces or eliminates indentations caused by expansion of the aluminum coil, thereby significantly improving the quality of the aluminum coil.

[0004] Regarding the above-mentioned related technologies, when uncoiling color-coated aluminum coils of different sizes, it is usually necessary to use a matching transport component to transport the aluminum coils to the clamping position of the uncoiler. However, due to the lack of adaptability design of the support structure and positioning device of the traditional uncoiler, it is difficult to achieve accurate positioning and rapid clamping of aluminum coils of various sizes. When the width or diameter of the aluminum coil changes, the existing positioning and clamping mechanism cannot be adaptively adjusted, which is prone to problems such as clamping offset and inaccurate positioning, thereby affecting the operating efficiency of the entire production line and the consistency of product quality. Therefore, there is an urgent need for an uncoiling machine suitable for color-coated aluminum coils of various sizes to solve the above technical problems. Summary of the Invention

[0005] In order to improve the operation efficiency of the production line and the consistency of product quality, the present invention provides a color-coated aluminum coil uncoiler suitable for various sizes.

[0006] The present invention provides a color-coated aluminum coil uncoiler suitable for various sizes, which adopts the following technical solutions: A color-coated aluminum coil uncoiler suitable for various sizes comprises a base plate and an uncoiling assembly arranged on the upper end surface of the base plate, the uncoiling assembly is located at one end of the base plate, and a sliding seat is provided at the end of the base plate away from the uncoiling assembly, the sliding seat is slidably connected to the upper end surface of the base plate, a support seat is provided above the sliding seat, a bidirectional screw is provided in the support seat, a sliding groove is provided on the upper end surface of the support seat, the sliding groove extends along the length direction of the support seat, the bidirectional screw is located at the sliding groove of the support seat, and clamping plates are provided at both ends of the support seat, and the two clamping plates are respectively threadedly connected to the two ends of the bidirectional screw The gear train is connected to the drive shaft by a threaded connection to the gear train, and the gear train is connected to the drive shaft by a threaded connection to the gear train.

[0007] By adopting the above technical solution, when aluminum coils of different sizes need to be transported to the uncoiler, the staff first places the aluminum coil on the support seat, and then starts the drive motor. The drive motor drives the bidirectional screw to rotate, thereby driving the two splints to move toward each other. At the same time, the rotation of the bidirectional screw drives the support screw to rotate, and under the action of the limit rod, the support seat is lifted and lowered. It not only realizes the operation of fixing the aluminum coil, but also adapts its height according to its size change while fixing the aluminum coil, thereby ensuring that the aluminum coil can be directly transported to the clamping position of the uncoiler assembly during subsequent transportation. Finally, the push cylinder is started to transport the aluminum coil, which is easy to operate and helps to improve work efficiency.

[0008] Optionally, the upper end surface of the support seat is fixedly connected to an arc seat, an arc groove is provided on the arc seat, and two baffles are provided on one side of the splint close to the arc seat, and the two baffles are respectively arranged on both sides of the splint, and the two baffles are arranged opposite to each other.

[0009] By adopting the above technical solution, when it is necessary to transport colored aluminum coils of different sizes, the staff will place the aluminum coils on the arc-shaped seat and then transport them. The baffle can prevent the aluminum coils from falling off during transportation, which is beneficial to improving the stability of the device.

[0010] Optionally, the unwinding assembly includes a vertical plate, which is vertically arranged on the upper end surface of the base plate, and a rotating disk is provided on the side of the vertical plate close to the support seat, which is rotatably connected to the top of the vertical plate, and a side of the rotating disk away from the vertical plate is fixedly connected to a column, and a sliding column is provided on the outer side of the column, an adjusting slot is provided in the sliding column, and the column is slidably connected to the adjusting slot of the sliding column, a threaded rod is provided in the sliding column, a threaded groove is provided in the column, and the threaded rod is threadedly connected to the threaded groove of the column, and a small motor is provided on the side of the sliding column away from the vertical plate, and the output shaft of the small motor The cam is fixedly connected to the threaded rod coaxially, and a plurality of connecting plates are provided on the outer side of the sliding column.

A rotating motor is provided on the side of the rotating disk away from the column, and the output shaft of the rotating motor passes through the vertical plate and is coaxially fixedly connected to the rotating disk.

[0011] By adopting the above technical solution, when the uncoiling assembly is needed for subsequent uncoiling of the aluminum coil, the staff first transports the aluminum coil to the clamping position of the uncoiling machine, and then starts the small motor. The small motor drives the threaded rod to rotate, thereby controlling the sliding column to move toward the rotating disk, and under the action of the connecting rod, drives the sliding plate to move along the limit groove, thereby tightening and fixing the position of the aluminum coil, and then starts the rotating motor to realize the uncoiling operation of the aluminum coil, which is easy to understand and implement and is conducive to improving work efficiency.

[0012] Optionally, an elastic steel plate is provided on the side of the sliding plate away from the column, the elastic steel plate is bent outward, a clamping block is provided at the bottom end of the elastic steel plate, the clamping block is located in the limiting groove, and the elastic steel plate is slidably connected to the rotating disk.

[0013] By adopting the above technical solution, when the aluminum coil is fixed by the uncoiler, the sliding plate drives the elastic steel plate to tension the aluminum coil outward.

[0015] By adopting the above technical solution, when the aluminum coil needs to be tensioned and fixed, the sliding plate moves outward, and at the same time drives the synchronous wheel to rotate. The rotation of the synchronous wheel drives the synchronous screw to rotate, and thus drives the connecting screw to rotate under the transmission of the bevel gear pair, thereby driving the adjusting ring to move on the connecting screw, and driving the stretching of the two ends of the elastic steel plate through the adjusting rod, thereby achieving fine adjustment of the curvature of the elastic steel plate, ensuring that different sizes of aluminum coils correspond to elastic steel plates with different curvatures, so that the elastic steel plate fully fits with the inner side of the aluminum coil, which is conducive to improving the adaptability of the device and improving work efficiency.

[0017] By adopting the above technical solution, after the aluminum coil is fixed, the staff starts the limit motor, and the limit motor drives the vertical limit arm to rotate, thereby limiting the position of the aluminum coil in the vertical direction to prevent it from shaking or detaching during the uncoiling process, which is beneficial to improving the stability of the device.

[0018] In summary, the present invention includes at least one of the following beneficial technical effects: 1. By setting the bottom plate, unwinding assembly, sliding seat, support seat, bidirectional screw, clamping plate, support screw, limiting rod, driving motor and pushing cylinder, when aluminum coils of different sizes need to be transported to the unwinding machine, the staff first places the aluminum coil on the supporting seat, and then starts the driving motor. The driving motor drives the bidirectional screw to rotate, thereby driving the two clamping plates to move toward each other. At the same time, the rotation of the bidirectional screw drives the support screw to rotate, and under the action of the limiting rod, the support seat is raised and lowered, which not only realizes the operation of fixing the aluminum coil, but also adapts to its size change while fixing the aluminum coil, thereby ensuring that the aluminum coil can be directly transported to the clamping position of the unwinding assembly during subsequent transportation. Finally, the pushing cylinder is started to transport the aluminum coil, which is easy to operate and conducive to improving work efficiency. 2. By setting up the arc seat and baffle, when it is necessary to transport colored aluminum coils of different sizes, the staff will place the aluminum coils on the arc seat and then transport them. The baffle can prevent the aluminum coils from falling off during transportation, which is beneficial to improve the stability of the device; 3. By setting up the elastic steel plate and the clamping block, when the aluminum coil is fixed by the uncoiler, the sliding plate drives the elastic steel plate to tension the aluminum coil outward. The arc-shaped elastic steel plate increases the contact area with the inner side of the aluminum coil, increases the tensioning force, and is conducive to improving the stability of the device.
