Description

Technical Field

[0001] This application relates to the field of steel uncoiling technology, and in particular to a material unloading rack for narrow strip color steel strips. Background Technology

[0002] During the processing of color steel strip coils, it is necessary to unwind the coil to unfold it into a single layer of color steel strip, thereby completing the subsequent processing of the single layer of color steel strip.

[0003] Currently, cylindrical unwinding machines are typically used for unwinding material rolls. During unwinding, the material roll is placed on a cylindrical unwinding shaft, and the rotation of the unwinding shaft unwinds the material.

[0004] However, for narrow strip-shaped color steel strips, since their width is less than the axial length of the unwinding shaft, the color steel strip on the cylindrical unwinding machine is prone to deviation and swaying during rotation, which not only affects the unwinding stability of the color steel strip, but also greatly reduces the work efficiency.

[0005] Among the aforementioned technologies, there is a defect of insufficient stability when feeding narrow strip color steel strips. Utility Model Content

[0006] To improve the stability of feeding narrow strip color steel strips, this application provides a feeding rack for narrow strip color steel strips.

[0007] The narrow strip color steel strip feeding rack provided in this application adopts the following technical solution:

[0008] A feeding rack for narrow strip color steel strip includes: a support assembly; a feeding assembly including a material tray, the material tray being horizontally disposed above the support assembly, the axis of the material tray extending vertically, the material tray being rotatably connected to the support assembly, allowing the material tray to rotate relative to the support assembly around its axis, the material tray being used to place and drive the narrow strip color steel strip roll to rotate horizontally; and a first limiting assembly including a plurality of limiting members, the plurality of limiting members being evenly distributed on the material tray, the limiting members abutting against the inner peripheral wall of the roll, so that the axis of the roll and the axis of the material tray both extend vertically and are located on the same straight line, the limiting members being used to horizontally limit the roll.

[0009] By adopting the above technical solution, the support component provides support, and the material tray of the feeding component is rotatably positioned above the support component. The narrow strip of color steel strip is placed on the material tray, and the axis of the material roll and the axis of the material tray both extend vertically. This allows the material roll to be fed by the horizontal rotation of the material tray relative to the support component. Furthermore, the material tray is equipped with several limiting components, which abut against the inner circumferential wall of the material roll to achieve a horizontal limiting effect on the material roll, ensuring that the axis of the material roll and the axis of the material tray are on the same straight line, thus improving the stability during feeding. Compared with the method of placing the material roll on a cylindrical unwinding shaft, the material tray of this feeding rack is horizontally positioned and rotates in the horizontal plane, and the axis of the material roll it carries extends vertically. This allows the material roll to be placed stably on the material tray, reducing the risk of the material roll deviating and swaying on the unwinding shaft due to the small width of the narrow strip of color steel strip. This helps to improve the stability of feeding, thereby improving feeding reliability and work efficiency.

[0010] Optionally, the feeding assembly includes a lifting ring disposed on the material tray, the lifting ring being used to drive the feeding assembly to move.

[0011] By adopting the above technical solution, the lifting ring is used to lift the feeding assembly and the support assembly that is rotatably connected to the feeding assembly, so as to facilitate the movement of the feeding frame between the feeding position and the material changing position, so as to realize feeding and material roll replacement after feeding a material roll is completed, reducing the difficulty of operation.

[0012] Optionally, it also includes a second limiting component, the second limiting component including a pressure plate, the pressure plate being disposed on the side of the material roll away from the material tray, the lifting ring being disposed in the middle of the material tray, the pressure plate having a clearance hole in the middle, the diameter of the clearance hole being larger than the horizontal length of the lifting ring, so that the pressure plate and the lifting ring are spaced apart, the pressure plate being detachable from the support component, and the pressure plate being used to limit the material roll in the vertical direction.

[0013] By adopting the above technical solution, the pressure plate of the second limiting component is located above the material roll to achieve the function of limiting the material roll in the vertical direction; the clearance hole in the middle of the pressure plate is used to avoid the lifting ring, so that the lifting ring can protrude from the pressure plate and ensure the lifting function is realized; since the diameter of the clearance hole is larger than the horizontal length of the lifting ring, when the material tray rotates and drives the lifting ring to rotate, the pressure plate can remain relatively stationary, reducing the risk of the pressure plate shifting and affecting the limiting effect on the material roll; in addition, the pressure plate is detachable, which makes it easy to remove the pressure plate when the material roll needs to be disassembled or replaced, reducing the difficulty of disassembly and assembly.

[0014] Optionally, the second limiting component includes a plurality of elastic elements, which are evenly distributed around the pressure plate. The first end of each elastic element is connected to the support component, and the second end of each elastic element is detachably connected to the pressure plate.

[0015] By adopting the above technical solution, several elastic elements are distributed around the circumference of the pressure plate, which can fix the pressure plate, restrict the rotation of the pressure plate, improve the reliability of the limit, and thus improve the stability of material feeding; in addition, the second end of the elastic element is detachably connected to the pressure plate, which can facilitate disassembly and reduce the difficulty of operation.

[0016] Optionally, the limiting member is a threaded member, the material tray is provided with a threaded hole, the threaded member is screwed into the threaded hole, so that the threaded member protrudes from the upper surface of the material tray, and the threaded member is used to abut against the inner peripheral wall of the material roll.

[0017] By adopting the above technical solution, the detachable connection between the threaded component and the threaded hole facilitates quick disassembly when it is necessary to replace the material roll or other situations that require the removal of the limiting component, thereby improving efficiency. Furthermore, by adjusting the height of the threaded component protruding from the upper surface of the material tray, a reliable limiting effect on the material roll can be achieved.

[0018] Optionally, the upper surface of the tray is provided with a rough layer, which is used to increase the friction between the tray and the coil.

[0019] By adopting the above technical solution, the rough layer can increase the friction between the material tray and the material roll, so that the unloading of the material roll and the rotation of the material tray can be synchronized. This avoids the problem that the material tray does not rotate when the material roll is unloaded, causing excessive wear on the lower side of the material roll under its own weight, which affects the quality of the color steel strip. Alternatively, it avoids the risk that the material roll cannot be driven to rotate due to the low friction between the material tray and the material roll when the material tray rotates, thus affecting the unloading efficiency.

[0020] Optionally, it also includes a guide assembly, which includes a first bracket, a second bracket, a first guide wheel, and a second guide wheel. The two ends of the first bracket are respectively connected to the support assembly and the first guide wheel, and the two ends of the second bracket are respectively connected to the pressure plate and the second guide wheel. The first guide wheel and the second guide wheel are respectively located on both sides of the color steel belt conveying direction, and the first guide wheel and the second guide wheel respectively abut against both sides of the color steel belt.

[0021] By adopting the above technical solution, the first bracket and the second bracket support the first guide wheel and the second guide wheel respectively, so that the first guide wheel and the second guide wheel can be set on both sides of the color steel strip at the material roll unloading output end, so as to realize the guiding function of the color steel strip and improve the stability and reliability of unloading.

[0022] Optionally, it also includes a drive component, which is disposed on the support component. The output end of the drive component is connected to the material tray, and the drive component drives the material tray to rotate horizontally around the axis of the material tray.

[0023] By adopting the above technical solution, the drive component drives the material tray to rotate, thereby enabling the material tray to rotate actively and realize the unloading of the material coil. This reduces the pulling force required for subsequent processes of unloading the material coil and reduces the risk of excessive tension on the color steel strip caused by excessive pulling force, which affects the quality of the color steel strip.

[0024] Optionally, the support assembly includes a support frame and an annular disk, the annular disk being mounted on the support frame and having an annular groove. The drive assembly includes a drive body and several rolling elements, the drive body being connected to the support frame, the output end of the drive body being movably inserted through the annular disk, the output end of the drive body being drively connected to the material tray, the drive body driving the material tray to rotate, and the rolling elements being movably disposed in the annular groove, the rolling elements causing the support assembly and the material tray to be spaced apart in the vertical direction.

[0025] By adopting the above technical solution, the support frame provides support, allowing the annular disk mounted on the support frame to be spaced apart from the ground for easy installation of the drive body. The output end of the drive body passes through the middle of the annular disk, and there is relative rotation between the output end of the drive body and the annular disk, preventing the rotation of the output end of the drive body from causing the annular disk to rotate. The output end of the drive body is connected to the material tray, thereby driving the material tray to rotate. The rotation of the material tray drives the material roll to actively unload, which helps to reduce the pulling force required for unloading. The upper surface of the annular disk has an annular groove, and the rolling element is movably disposed in the annular groove. Since the drive body is located on the support frame and passes through the connection between the annular disk and the material tray, the relative position of the annular disk and the material tray in the vertical direction is fixed, thereby clamping the rolling element between the annular groove and the material tray. Because the rolling element keeps the support assembly and the material tray spaced apart in the vertical direction, the rolling element can provide support when the material tray rotates relative to the support assembly. The rolling of the rolling element in the annular groove reduces the friction when the material tray rotates, thereby improving the stability of unloading.

[0026] Optionally, the tray has a frame structure, and in the horizontal plane, the rotation diameter of the tray is less than the minimum horizontal length of the support assembly.

[0027] By adopting the above technical solutions, the overall weight of the tray in the frame structure can be reduced, thus facilitating overall movement; the rotation diameter of the tray is smaller than the minimum horizontal length of the support components, which can reduce the risk of interference with other structures when the tray rotates.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The support assembly provides support, and the material tray of the feeding assembly is rotatably positioned above the support assembly. The narrow strip of color steel strip is placed on the material tray, and the axis of the material roll and the axis of the material tray both extend vertically. This allows the material roll to be fed by the horizontal rotation of the material tray relative to the support assembly. Furthermore, the material tray is equipped with several limiting components, which abut against the inner circumferential wall of the material roll to achieve a horizontal limiting effect, ensuring that the axis of the material roll is aligned with the axis of the material tray, thus improving the stability during feeding. Compared to the method of placing the material roll on a cylindrical unwinding shaft, the material tray of this feeding rack is horizontally positioned and rotates in the horizontal plane, with the axis of the material roll it carries extending vertically. This allows the material roll to be placed stably on the material tray, reducing the risk of the material roll deviating and swaying on the unwinding shaft due to the small width of the narrow strip of color steel strip. This helps to improve the stability of feeding, thereby improving feeding reliability and work efficiency.

[0030] 2. Lifting rings are used to lift the feeding assembly and the support assembly that is rotatably connected to the feeding assembly, so as to facilitate the movement of the feeding frame between the feeding position and the material changing position, so as to realize feeding and material roll replacement after feeding a material roll, reducing the difficulty of operation;

[0031] 3. The pressure plate of the second limiting component is located above the material roll to limit the material roll in the vertical direction; the clearance hole in the middle of the pressure plate is used to avoid the lifting ring, so that the lifting ring can protrude from the pressure plate and ensure the lifting action is realized; since the diameter of the clearance hole is larger than the horizontal length of the lifting ring, when the material tray rotates and drives the lifting ring to rotate, the pressure plate can remain relatively stationary, reducing the risk of displacement caused by the rotation of the pressure plate affecting the limiting effect of the material roll; in addition, the pressure plate is detachable, which makes it easy to remove the pressure plate when the material roll needs to be disassembled or replaced, reducing the difficulty of disassembly and assembly.

[0037] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings, and are used only for ease of description and simplification of operation, not to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0039] like Figure 1 As shown in the embodiment of this application, a feeding rack (hereinafter referred to as "feeding rack") for narrow strip color steel strip is disclosed. The feeding rack includes a support component 1, a feeding component 2 and a first limiting component 3, which are used to feed the material roll 100 of narrow strip color steel strip so as to process the single layer of narrow strip color steel strip (hereinafter referred to as "color steel strip").

[0040] like Figure 1 , Figure 2 and Figure 3As shown, the support component 1 provides support, and the feeding component 2 includes a material tray 21. The material tray 21 is used to place and drive the narrow strip of color steel strip coil 100 to rotate horizontally, thereby achieving feeding. The material tray 21 is horizontally positioned above the support component 1, and the axis of the material tray 21 extends vertically. The material tray 21 is rotatably connected to the support component 1, allowing the material tray 21 to rotate relative to the support component 1 around its axis. Because the weight of the coil 100 exerts a downward pressure on the material tray 21, there is no vertical relative movement between the upper material tray 21 and the lower support component 1, preventing the material tray 21 from detaching upwards and causing a safety hazard. The material tray 21 of the feeding component 2 is rotatably positioned above the support component 1. The narrow strip color steel strip coil 100 is placed on the material tray 21, and the axis of the coil 100 and the axis of the material tray 21 both extend vertically, so that the material coil 100 can be fed out by the horizontal rotation of the material tray 21 relative to the support component 1, so as to process the single layer of color steel strip in the future.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, the first limiting component 3 includes several limiting members 31, which are evenly distributed on the material tray 21. The cross-section of the material roll 100 is annular, and the limiting members 31 abut against the inner peripheral wall of the material roll 100, so that the axis of the material roll 100 and the axis of the material tray 21 both extend vertically and are on the same straight line, thereby enabling the limiting members 31 to be used to horizontally limit the material roll 100 and improve the stability during material feeding.

[0042] Compared to the method of mounting the material roll 100 on a cylindrical unwinding shaft, the material tray 21 of this unwinding rack is horizontally positioned and rotates in the horizontal plane. The axis of the material roll 100 it carries extends vertically, thus ensuring the material roll 100 is stably placed on the tray 21. This reduces the risk of the material roll 100 deviating and swaying on the unwinding shaft due to its narrow width, which is common with narrow strip-shaped color steel strips. This improves the stability of unwinding, thereby enhancing unwinding reliability and work efficiency. Multiple sets of limiting members 31 can be provided, with each set having a different distance from the center of the tray 21 to accommodate material rolls 100 with different inner diameters. The rotation of the tray 21 can be driven rotation, achieved by a pulling structure in subsequent processes of the unwinding rack, which pulls the output end of the material roll 100, allowing the material roll 100 to rotate relative to the support assembly 1 for unwinding.

[0043] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the limiting member 31 is a threaded member, and the material tray 21 has a threaded hole. The threaded member is screwed into the threaded hole, and the detachable connection between the threaded member and the threaded hole facilitates quick disassembly when the limiting member 31 needs to be disassembled, such as when the material roll 100 needs to be replaced, thus improving efficiency. The threaded member protrudes from the upper surface of the material tray 21 to abut against the inner peripheral wall of the material roll 100. By adjusting the height of the threaded member protruding from the upper surface of the material tray 21, a reliable limiting effect on the material roll 100 can be achieved. The limiting member 31 can be a bolt or screw, screwed into the threaded hole. In other embodiments, the limiting member 31 can also adopt different forms of limiting structures such as mechanical limiting blocks, hydraulic or pneumatic clamping devices.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the rotation of the material tray 21 can also include active rotation. The feeding rack also includes a drive assembly 6 to drive the material tray 21 to rotate. The drive assembly 6 is located on the support assembly 1, and the output end of the drive assembly 6 is connected to the material tray 21. The drive assembly 6 drives the material tray 21 to rotate horizontally around its axis. The drive assembly 6 drives the material tray 21 to rotate, thereby enabling the material tray 21 to rotate actively and feed the material coil 100. This reduces the pulling force required for subsequent processes of feeding the material coil 100, and lowers the risk of excessive tension on the color steel strip due to excessive pulling force, which could affect the quality of the color steel strip.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the support assembly 1 includes a support frame 11 and an annular disk 12, with the annular disk 12 mounted on the support frame 11. The support frame 11 provides support, allowing the annular disk 12 mounted on the support frame 11 to be spaced apart from the ground, so that the drive body 61 can be installed below the annular disk 12.

[0046] The drive assembly 6 includes a drive body 61 and several rolling elements 62. The drive body 61 is connected to the support frame 11. The output end of the drive body 61 is movably inserted through the central hole of the annular disk 12. The output end of the drive body 61 is connected to the material tray 21, and the drive body 61 drives the material tray 21 to rotate. The output end of the drive body 61 is inserted through the middle of the annular disk 12, and there is relative rotation between the output end of the drive body 61 and the annular disk 12 to prevent the rotation of the output end of the drive body 61 from causing the annular disk 12 to rotate. The output end of the drive body 61 is connected to the material tray 21, thereby driving the material tray 21 to rotate. The rotation of the material tray 21 drives the material roll 100 to actively unload, which helps to reduce the pulling force required for unloading. The drive body 61 can be a different type of drive power source, such as an electric motor, a hydraulic motor, or a pneumatic motor.

[0047] like Figure 1 , Figure 2 and Figure 3 As shown, an annular groove 13 is provided on the annular disk 12, and rolling elements 62 are rolled in the annular groove 13. The rolling elements 62 keep the support assembly 1 and the material tray 21 vertically spaced apart. The annular groove 13 is provided on the upper surface of the annular disk 12, and multiple rolling elements 62 can roll in the annular groove 13. Since the drive body 61 is connected to the support frame 11 and is located below the annular disk 12, and the output end of the drive body 61 passes through the connection between the annular disk 12 and the material tray 21, the relative position of the annular disk 12 and the material tray 21 in the vertical direction is fixed, thereby clamping the rolling elements 62 between the annular groove 13 and the material tray 21. Since the rolling elements 62 keep the support assembly 1 and the material tray 21 vertically spaced apart, when the material tray 21 rotates relative to the support assembly 1, the rolling elements 62 can provide support, and the rolling of the rolling elements 62 in the annular groove 13 reduces the friction between the material tray 21 and the support assembly 1 when it rotates, thereby improving the stability of material feeding. In other embodiments, an annular groove 13 may also be provided on the lower side of the material tray 21, so that the rolling element 62 can be clamped between two annular grooves 13 in the vertical direction, thereby optimizing the rolling support effect and preventing the rolling element 62 from coming off. The rolling element 62 may be a spherical ball, and the diameter and number of the ball are set according to the actual situation so that the material tray 21 and the annular tray 12 are spaced apart in the vertical direction.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the upper surface of the tray 21 is provided with a roughening layer 23, which is used to increase the friction between the tray 21 and the coil 100. The roughening layer 23 increases the friction between the tray 21 and the coil 100, allowing the feeding of the coil 100 and the rotation of the tray 21 to proceed synchronously. This avoids the problem of the tray 21 not rotating when the coil 100 is being fed, causing excessive wear on the lower side of the coil 100 under its own weight, thus affecting the quality of the color steel strip. Alternatively, when the tray 21 rotates actively, it avoids the risk that the low friction between the tray 21 and the coil 100 will prevent the coil 100 from rotating, thus affecting the feeding efficiency. The material, thickness, and other parameters of the roughening layer 23 can be determined according to actual conditions, as long as it increases the friction between the tray 21 and the lower surface of the coil 100.

[0049] Optionally, both the tray 21 and the support frame 11 can be frame structures. Their specific structures can be set as needed to achieve stable support and reduce weight through the frame structure.

[0050] like Figure 1 , Figure 2 and Figure 3As shown, the material tray 21 includes a connecting part 211, a supporting part 212, and a carrying part 213. The connecting part 211 can be a rotating shaft passing through the center of the annular disk 12, and is connected to the rotating shaft through the output end of the drive body 61 to achieve rotation. Bearing structures can be provided between the outer peripheral wall of the connecting part 211 and the inner peripheral wall of the annular groove 13, and between the output end of the drive body 61 and the annular groove 13, so as to make the rotation of the material tray 21 more stable and improve the stability of the material roll 100 feeding. The supporting part 212 is provided on the connecting part 211. The supporting part 212 can be a cylindrical structure with a diameter larger than that of the connecting part 211, so that the supporting part 212 protrudes from the lower surface of the connecting part 211 and can abut against the rolling element 62. The carrying part 213 can be a plurality of horizontally extending and evenly distributed support pillar structures. One end of the carrying part 213 is connected to the supporting part 212, and the carrying part 213 is used to carry the material roll 100.

[0051] In the horizontal plane, the rotation diameter of the tray 21 is less than the minimum horizontal length of the support assembly 1. The frame structure of the tray 21 reduces the overall weight, thereby facilitating overall movement. The smaller rotation diameter of the tray 21 compared to the minimum horizontal length of the support assembly 1 reduces the risk of interference with other structures when the tray 21 rotates. In this embodiment, the rotation diameter of the tray 21 is the horizontal distance from the end of the bearing portion 213 furthest from the support portion 212 to the center of the support portion 212.

[0052] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the feeding assembly 2 includes a lifting ring 22, which is mounted on the material tray 21 and used to move the feeding assembly 2. The lifting ring 22 is used to lift the feeding assembly 2 and the support assembly 1 rotatably connected to the feeding assembly 2, so as to facilitate the movement of the feeding rack between the feeding position and the material changing position, thereby enabling feeding and changing of the material roll 100 after feeding, reducing the difficulty of operation. The lifting ring 22 can be a circular ring structure or an inverted U-shaped structure, which can be hooked through the lifting structure to move the feeding rack between the material changing position, such as the ground, and the feeding position. Specifically, by lifting, the feeding rack is moved to the ground to realize the operation of changing the material roll 100 and feeding; by moving the feeding rack to the feeding position, the material roll 100 is fed.

[0053] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the feeding rack also includes a second limiting component 4. The second limiting component 4 includes a pressure plate 41, which is located on the side of the material coil 100 away from the material tray 21. The pressure plate 41 of the second limiting component 4 is located above the material coil 100, thereby limiting the material coil 100 in the vertical direction. A lifting ring 22 is located in the middle of the material tray 21. The pressure plate 41 has a clearance hole 411 in the middle, which is used to avoid the lifting ring 22, so that the pressure plate 41 has a ring structure and the lifting ring 22 can protrude upward from the pressure plate 41, ensuring the lifting function. The diameter of the pressure plate 41 is larger than the diameter of the material coil 100, so as to achieve a reliable limiting effect on the material coil 100 in the vertical direction. The setting of the pressure plate 41 can alleviate the problem of vertical limiting for narrow strip-shaped color steel strips with small width, thereby achieving reliable limiting of the material coil 100 and improving stability.

[0054] The diameter of the clearance hole 411 is larger than the horizontal length of the lifting ring 22, so that the pressure plate 41 and the lifting ring 22 are horizontally spaced apart. The pressure plate 41 is detachable from the connecting support assembly 1 and is used to limit the material roll 100 in the vertical direction. Because the diameter of the clearance hole 411 is larger than the horizontal length of the lifting ring 22, when the material tray 21 rotates and drives the lifting ring 22 to rotate, the pressure plate 41 can remain relatively stationary, reducing the risk that the offset caused by the rotation of the pressure plate 41 will affect the limiting effect on the material roll 100. Furthermore, the pressure plate 41 is detachably connected to the support assembly 1, which makes it easy to remove the pressure plate 41 when it is necessary to disassemble or replace the material roll 100, reducing the difficulty of disassembling and replacing the material roll 100.

[0055] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the second limiting component 4 includes a plurality of elastic elements 42, which are evenly distributed around the circumference of the pressure plate 41. The first end of each elastic element 42 is connected to the support component 1, and the second end of each elastic element 42 is detachably connected to the pressure plate 41. The plurality of elastic elements 42 distributed around the circumference of the pressure plate 41 can achieve circumferential fixation of the pressure plate 41, restricting its rotation and improving the reliability of the limiting mechanism, thereby improving the stability of material feeding. Furthermore, the detachable connection between the second end of the elastic element 42 and the pressure plate 41 facilitates disassembly and reduces operational difficulty. The pressure plate 41 can be an annular plate with a hook on its lower side, such as a straight rod mounted on a groove. The elastic element 42 can be a spring with a hook at its second end, which hooks onto the straight rod, achieving a detachable connection between the elastic element 42 and the pressure plate 41.

[0056] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the feeding rack further includes a guide assembly 5, which includes a first bracket 51, a second bracket 52, a first guide wheel 53, and a second guide wheel 54. The two ends of the first bracket 51 are respectively connected to the support assembly 1 and the first guide wheel 53, and the two ends of the second bracket 52 are respectively connected to the pressure plate 41 and the second guide wheel 54. The first guide wheel 53 is rotatably connected to the first bracket 51, and the second guide wheel 54 is rotatably connected to the second bracket 52. The first guide wheel 53 and the second guide wheel 54 are respectively located on both sides of the color steel strip conveying direction, and the first guide wheel 53 and the second guide wheel 54 respectively abut against the opposite sides of the color steel strip. The structure of the first bracket 51 and the second bracket 52 is not limited; as long as the first bracket 51 and the second bracket 52 can support the first guide wheel 53 and the second guide wheel 54 respectively, so that the first guide wheel 53 and the second guide wheel 54 can be located on both sides of the color steel strip at the feeding output end of the material roll 100, thereby achieving the guiding effect on the color steel strip and improving the stability and reliability of feeding.

[0057] It is understandable that the feeding rack also includes necessary structures for connection, support, drive, limit and control functions to enable the feeding rack to operate normally; the shape, size, material and quantity of each part of the feeding rack can be determined as needed, as long as it can achieve the corresponding function.

[0058] The implementation principle of a feeding rack for narrow strip color steel strips in this application embodiment is as follows: A roll 100 of the narrow strip color steel strip is placed on a tray 21, with the axis of the roll 100 extending vertically and aligned with the axis of the tray 21. A first limiting component 3 horizontally limits the roll 100, preventing horizontal displacement and ensuring feeding stability. The output end of the roll 100 is clamped between a first guide wheel 53 and a second guide wheel 54 to limit the output direction of the color steel strip, improving the stability of the output end and preventing the roll 100 from loosening during movement and affecting the feeding effect. Subsequently, the elastic... The second end of component 42 is hooked onto pressure plate 41, which limits the vertical movement of material roll 100. The lifting structure hooks onto lifting ring 22, moving the unloading rack to the unloading position. At least one of the two driving methods—pulling the output end of material roll 100 through a pulling structure in subsequent processes and driving component 6 to rotate material tray 21—achieves the output action of material roll 100, causing material tray 21 to rotate relative to support component 1, thereby achieving stable unloading of material roll 100. This helps improve production efficiency, ensure product quality, reduce operating difficulty and maintenance costs, and has strong practicality and market promotion value.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
