Description

Technical Field

[0001] This utility model belongs to the field of uncoiler technology, specifically relating to an uncoiler drum with an adjustable support arm. Background Technology

[0002] An uncoiler is an industrial machine used to unwind and smoothly transport coiled strip materials (such as metal sheets, paper, films, fabrics, etc.) to subsequent processing equipment. It is widely used in production lines in industries such as metallurgy, papermaking, printing, packaging, and building materials.

[0003] The uncoiler drum is the core component of the uncoiler, responsible for fixing the roll material and ensuring its stable unfolding. It uses an expansion and contraction mechanism (such as a four-sided pyramid wedge type or a hydraulic expansion sleeve type) to tightly fix the inner hole of the roll material, ensuring that the roll material does not slip during rotation.

[0004] For example, in the prior art, Chinese utility model patent with authorization announcement number CN222695662U discloses "an adjustable steel coil uncoiling machine", which includes a machine base, a coil disposed on one side of the machine base, an automatic adjustment and pressing mechanism disposed at the top of the machine base, and a limit mechanism disposed above the automatic adjustment and pressing mechanism.

[0005] While existing steel coil uncoiling machines, including those mentioned above, can meet general usage requirements, they lack measures to limit the ends of the coil. This makes them prone to edge scattering and displacement due to uneven tension, coil vibration, or material flexibility, resulting in misalignment at the end faces.

[0006] To address the aforementioned problems, this utility model proposes an uncoiler drum with an adjustable support arm. Utility Model Content

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Please see Figures 1-5 The present invention provides the following technical solution: an uncoiling machine drum with adjustable support arms, including a base 1, a support frame 2 fixed to the top of the base 1, a first transmission roller 3 rotatably installed on the top of the support frame 2, and a drum body 4 fixed to the end of the first transmission roller 3. The drum body 4 includes: a first turntable 41, a second turntable 42, an electric push rod 43, multiple inner support plates 44, a baffle 45, multiple first flip arms 46, multiple second flip arms 47, and an adjustment mechanism 48.

[0044] Furthermore, by Figure 1 and Figure 2As shown, in this embodiment, turntable 41 is fixed to one end of drive roller 3, turntable 42 is located on one side of turntable 41 and directly opposite it, electric push rod 43 is fixed between turntable 41 and electric push rod 43, multiple inner support plates 44 are evenly distributed around electric push rod 43 along the circumferential direction, and two symmetrically distributed baffles 45 are movably installed on each inner support plate 44, one end of multiple first-stage tilting arms 46 is hinged to turntable 41 and the other end is hinged to inner support plates 44, one end of multiple second-stage tilting arms 47 is hinged to turntable 42 and the other end is hinged to inner support plates 44, and adjustment mechanism 4... 8 is used to adjust the initial distance between the two baffles 45. After adopting the above scheme, when in use, the first drive roller 3 is rotatably installed on the top of the support frame 2. The first drive roller 3 is driven by an external power source to rotate. When the first drive roller 3 rotates, the first turntable 41, which is fixedly connected to its end, will rotate accordingly. Since the first turntable 41, the second turntable 42, and multiple inner support clamps 44 are interconnected through the first flip arm 46 and the second flip arm 47, the second turntable 42 and the inner support clamps 44 will also rotate together with the first turntable 41, thereby driving the rolled material on the roll body 4 to rotate and realize the unwinding operation.

[0045] The electric push rod 43 is fixed between the first turntable 41 and the second turntable 42. By controlling the extension and retraction of the electric push rod 43, the distance between the first turntable 41 and the second turntable 42 can be changed. When the electric push rod 43 extends, the distance between the first turntable 41 and the second turntable 42 increases. At this time, the first tilting arm 46 and the second tilting arm 47 will push the inner support plate 44 to expand outward. Conversely, when the electric push rod 43 retracts, the distance between the first turntable 41 and the second turntable 42 decreases, and the inner support plate 44 will retract inward. The position of the inner support plate 44 can be adjusted according to the inner diameter of the coil, so that the inner support plate 44 is tightly pressed against the inner wall of the coil, ensuring that the coil will not shake during the unwinding process.

[0046] Two symmetrically distributed baffles 45 are movably installed on each inner support plate 44. The adjustment mechanism 48 is used to adjust the initial distance between the two baffles 45. By adjusting the distance between the baffles 45, different widths of roll material can be accommodated. When placing the roll material, the roll material is placed between the two baffles 45 so that the baffles 45 can limit the roll material and prevent the roll material from moving axially during the unwinding process. This avoids edge scattering and displacement caused by uneven tension, roll vibration or material flexibility, which can lead to misalignment of the end face.

[0047] It should be noted that the first transmission roller 3 is a hollow structure for threading cables, and it is connected to the electric push rod 43 by a rotatable electrical connector to avoid cable tangling.

[0048] Optionally, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the adjustment mechanism 48 includes a guide slider 481 and a bidirectional threaded screw 482. The guide slider 481 is fixed to the bottom end of the baffle 45. A guide groove 441 for the guide slider 481 to be embedded is provided on the outer wall of the inner support plate 44. The bidirectional threaded screw 482 is rotatably installed in the guide groove 441 and threadedly connected to the guide slider 481. With the above solution, when it is necessary to adjust the initial distance of the baffle 45, the bidirectional threaded screw 482 is rotated. Since the bidirectional threaded screw 482 is threadedly connected to the guide slider 481, the bidirectional threaded screw 482 can drive the two guide sliders 481 to move towards or away from each other along the guide groove 441 when rotating, and at the same time drive the baffle 45 to move towards or away from each other along the guide groove 441, thereby adjusting the initial distance between the two baffles 45.

[0049] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown in this embodiment, the adjustment mechanism 48 further includes a handwheel 483, which is fixed to one end of the bidirectional threaded screw 482. With the above solution, when in use, the handwheel 483 makes it easy to apply force, which facilitates the operator to rotate the bidirectional threaded screw 482.

[0050] When it is necessary to adjust the initial spacing of the baffle 45, the operator uses the handwheel 483 to rotate the double-ended threaded screw 482.

[0051] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the outer wall of the guide slider 481 is attached to the inner wall of the guide groove 441. With the above solution, when the adjustment mechanism 48 drives the guide slider 481 to move through the bidirectional threaded screw 482 during use, the attachment between the guide slider 481 and the inner wall of the guide groove 441 ensures that the baffle 45 can only move linearly along the direction defined by the guide groove 441, so that the guide slider 481 will not deviate laterally or shake during the movement, so that the uncoiler can accurately adapt to rolls of different widths and ensure the stability of the axial position of the roll during the uncoiling process.

[0052] Preferably, by Figure 1 , Figure 2 and Figure 5As shown, this embodiment further includes: multiple reinforcing ribs 451, which are fixed at equal intervals to the outer wall of the baffle 45. With the above solution, during use, when the uncoiler is working, the coiled material will generate centrifugal force and inertial force during rotation. These forces will act on the baffle 45, causing it to bear a certain pressure. The reinforcing ribs 451 can disperse the pressure on the baffle 45, avoiding stress concentration in a certain part of the baffle 45. When the force acts on the baffle 45, the reinforcing ribs 451 can transfer the force to a larger area, thereby reducing the stress borne per unit area, enhancing the overall structural strength of the baffle 45, and making it less prone to deformation or damage.

[0053] Preferably, by Figure 1 As shown in this embodiment, the support frame 2 includes: a side bracket 21 fixed to one end of the top of the base 1 and a seated bearing 22 fixed to the top of the side bracket 21. The first drive roller 3 is rotatably mounted on the top of the side bracket 21 using the seated bearing 22. With the above solution, when in use, the side bracket 21 is fixed to one end of the top of the base 1, providing basic support and stability for the entire support structure. It transmits the weight from the first drive roller 3 and the main body of the drum 4 and the force generated during the working process to the base 1, ensuring the stability of the entire uncoiler during operation.

[0054] The seated bearing 22 is fixed to the top of the side bracket 21. It provides a precise positioning and support point for the first drive roller 3. Through the seated bearing 22, the first drive roller 3 can be accurately installed on the side bracket 21, ensuring that the first drive roller 3 rotates more stably.

[0055] Preferably, by Figure 1 and Figure 3 As shown, this embodiment further includes: a second transmission roller 5 and a hexagonal rod 6. A support frame 2 is also fixed at the other end of the top of the base 1. The second transmission roller 5 is rotatably mounted on the top of the side bracket 21 using a bearing 22. A hexagonal insertion hole 51 is provided in the second transmission roller 5. The hexagonal rod 6 is fixed to the outer wall of the second turntable 42 and embedded in the hexagonal insertion hole 51. With the above scheme, when in use, the first transmission roller 3 starts to rotate under the drive of an external power source. Since the first turntable 41 is fixed at one end of the first transmission roller 3, the first turntable 41 will rotate synchronously with the first transmission roller 3. The first turntable 41 and the second turntable 42 are connected by an electric push rod 43, a first flipping arm 46 and a second flipping arm 47, so that the second turntable 42 will also rotate with the first turntable 41.

[0056] At this time, the hexagonal rod 6 fixed on the outer wall of the second turntable 42 will rotate accordingly. The hexagonal rod 6 is embedded in the hexagonal insertion hole 51 inside the second transmission roller 5. Due to the structural characteristics of the hexagon, the hexagonal rod 6 and the hexagonal insertion hole 51 form a tight fit, which can effectively transmit torque. The second transmission roller 5 will rotate synchronously with the first transmission roller 3 under the drive of the hexagonal rod 6, thereby realizing the power transmission and synchronous operation between the two transmission rollers, ensuring the stability and consistency of the roll body 4 during the rotation process, which is conducive to the smooth unwinding of the roll.

[0057] Preferably, by Figure 1 As shown in this embodiment, two support frames 2 are provided on the base 1 to support the first drive roller 3. With the above solution, the first drive roller 3 is a key component in the uncoiler. It drives the main body of the roll 4 to rotate so as to realize the unwinding of the roll. The two support frames 2 can provide stable support for the first drive roller 3, and evenly distribute the weight of the first drive roller 3 and the force generated during operation to the support frame 2 and the base 1. This prevents the first drive roller 3 from tilting, bending or vibrating due to uneven force, and ensures that the first drive roller 3 can rotate smoothly.

[0058] It should be noted that the electric actuator 43 is a commercially available standard device with a built-in power switch. Those skilled in the art can make conventional selections according to their needs. Its working principle is common knowledge known to those skilled in the art and has been fully disclosed in the prior art, so it will not be elaborated further in this article.

[0059] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0060] Components not described in detail in this article are existing technologies.

[0061] The working principle and usage process of this utility model: When the uncoiling drum of this utility model is in use, the No. 1 transmission roller 3 is rotatably installed on the top of the support frame 2. The No. 1 transmission roller 3 is driven by an external power source to rotate.

[0062] When the first drive roller 3 rotates, the first turntable 41, which is fixedly connected to its end, will rotate accordingly. Since the first turntable 41, the second turntable 42, and multiple inner support plates 44 are interconnected through the first flip arm 46 and the second flip arm 47, the second turntable 42 and the inner support plates 44 will also rotate together with the first turntable 41, thereby driving the coil material sleeved on the main body 4 of the drum to rotate and realize the unwinding operation.

[0063] The electric push rod 43 is fixed between the first turntable 41 and the second turntable 42. By controlling the extension and retraction of the electric push rod 43, the distance between the first turntable 41 and the second turntable 42 can be changed. When the electric push rod 43 extends, the distance between the first turntable 41 and the second turntable 42 increases. At this time, the first tilting arm 46 and the second tilting arm 47 will push the inner support plate 44 to expand outward.

[0064] Conversely, when the electric push rod 43 retracts, the distance between turntable 41 and turntable 42 decreases, and the inner support plate 44 retracts inward. The position of the inner support plate 44 can be adjusted according to the inner diameter of the coil, so that the inner support plate 44 presses tightly against the inner wall of the coil, ensuring that the coil does not shake during the unwinding process.

[0065] Two symmetrically distributed baffles 45 are movably installed on each inner support plate 44. The adjustment mechanism 48 is used to adjust the initial distance between the two baffles 45. By adjusting the distance between the baffles 45, different widths of roll material can be accommodated. When placing the roll material, the roll material is placed between the two baffles 45 so that the baffles 45 can limit the roll material and prevent the roll material from moving axially during the unwinding process. This avoids edge scattering and displacement caused by uneven tension, roll vibration or material flexibility, which can lead to misalignment of the end face.

[0066] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
