Description

Technical Field

[0001] The utility model relates to the technical field of coiled materials, in particular to a composite color-coated aluminum coiled material. Background Art

[0002] Color-coated aluminum coil, as the name implies, is to paint and color the surface of the aluminum substrate. Common ones include fluorocarbon color-coated aluminum coil and polyester color-coated aluminum coil, which are widely used in aluminum-plastic panels, industrial factory roofs and walls, aluminum blinds, composite panels, aluminum ceilings, cans, and electronic products. Color-coated aluminum coil coatings are divided into: polyester coated aluminum coil and fluorocarbon coated aluminum coil. The polyester coating formed by multiple baking coatings on the surface of the aluminum plate can form a firmly attached continuous solid film with protective decorative properties. It is an anti-UV coating. The polyester resin uses a high molecular polymer containing an ester bond in the main chain as a monomer, and adds alkyd resin. The ultraviolet absorber can be divided into matte and high-gloss series according to the glossiness. It can give color aluminum products rich colors, good gloss and smoothness, as well as superior texture and feel, and can also increase the sense of hierarchy and three-dimensionality. It can protect objects from being exposed to the atmosphere, being attacked by ultraviolet rays, wind, rain, frost, snow and ice; due to temperature differences, freeze-thaw cycles, corrosive gases and microorganisms, the coating can play a protective role. Especially suitable for interior decoration and advertising boards.

[0003] The existing composite color-coated aluminum coils still have certain defects during use. For example, a composite color-coated aluminum coil disclosed in the utility model with authorization announcement number CN219883435U has weak strength and poor practicality, and the adjustment mechanism set is not practical. Among them, if the matching connection between the positioning ball and the positioning slide groove is very tight, it is convenient for the coil unwinding operation, but it is inconvenient for the staff to push the connecting slide rod outward or inward, which makes it inconvenient to adjust the overall length. If the matching connection between the positioning ball and the positioning slide groove is not tight, it is convenient for the staff to push the connecting slide rod to adjust the overall length, but it is not conducive to ensuring the stability of the coil unwinding operation. It is difficult to find the best balance between the two. To this end, we design a composite color-coated aluminum coil to solve the above technical problems. Utility Model Content

[0004] The utility model aims to provide a composite color-coated aluminum coil to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A composite color-coated aluminum coil comprises an aluminum coil, which is wound around the outside of a winding roller, an adjusting component is arranged inside the winding roller, the aluminum coil comprises a substrate, a primer, a fireproof layer, an EVA material layer, an expanded glass microsphere layer and an outer cold-rolled plate, the substrate is the innermost layer, the upper and lower surfaces of the substrate are both provided with a primer, the outer surface of the primer is provided with a fireproof layer, the outer surface of the fireproof layer is provided with an EVA material layer, the outer surface of the EVA material layer is provided with an expanded glass microsphere layer, the outer surface of the expanded glass microsphere layer is provided with an outer cold-rolled plate, the outer layer The cold-rolled plate is provided with reinforcing ribs, and the upper and lower surfaces of the substrate are respectively provided with a plurality of recessed grooves, and the recessed grooves on both sides are staggered.

Receiving grooves are symmetrically provided on the left and right sides of the winding roller, and an inner rod corresponding to the inner rod is slidably inserted in the receiving groove. A push-pull circular plate is provided at one end of the two inner rods away from each other, and a vertical plate is provided on the outer surface of the push-pull circular plate. A plurality of groups of clamping mechanisms are evenly provided on the outer surface of the inner rod along its length direction.

[0007] As a preferred solution of the utility model: each set of clamping mechanisms includes two grooves opened on the outer surface of the inner rod, and the two grooves are symmetrically distributed on the upper and lower sides of the outer side of the inner rod. A clamping column is slidably provided in the groove, and a spring is provided on the inner bottom wall of the groove. The other end of the spring is fixedly connected to the clamping column, and the end of the clamping column away from the spring is an outwardly convex arc surface structure, and a limiting groove matching the clamping column is opened on the inner wall of the accommodating groove, and a guide groove is opened on one side of the inner wall of the accommodating groove along the circumferential rotation direction of the unwinding of the aluminum coil, and the guide groove corresponds to the limiting groove one by one, and the limiting groove is connected to the corresponding guide groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, under the action of the spring force, when the clamping column is clamped into the limit groove, the inner rod and the winding roller cannot send lateral relative movement. At this time, the vertical plate is in a vertical state. Moreover, when the aluminum coil rotates clockwise to unwind, the winding roller rotates clockwise and drives the inner rod to rotate clockwise. Without the action of artificial external force, the clamping column has no tendency to move toward the guide groove. When the length needs to be adjusted, instead of directly pushing and pulling the inner rod, the vertical plate is first used to push and pull the circular plate clockwise, thereby driving the inner rod to actively rotate clockwise. In this process, the clamping column is easily separated from the limit groove with the help of the guide groove. And until it is separated from the guide groove, at this time the vertical plate is inclined due to being rotated at a certain angle, then, push and pull the inner rod to the appropriate position, and then rotate the vertical plate to its original vertical state, so that the card column can also return to its original vertical state and be stuck in the new limit groove at this time. If it is not stuck in, just push and pull the position of the inner rod slightly again to ensure that the card column is stuck in the adjacent limit groove to complete the adjustment of the overall length. That is, the device can ensure tight clamping and high stability, and can easily release the clamping and adjust the overall length of the device, thereby improving applicability. The operation is simple and convenient, and it is worthy of promotion.

At the same time, it also has the functions that meet the various performance requirements of color-coated aluminum coils, such as water resistance, corrosion resistance, vibration resistance, thermal insulation and sound insulation, etc. BRIEF DESCRIPTION OF THE DRAWINGS

The aluminum coil 1 comprises a substrate 9, a primer layer 8, a fireproof layer 7, an EVA material layer 3, an expanded glass microsphere layer 6 and an outer cold-rolled plate 4. The substrate 9 is the innermost layer. The upper and lower surfaces of the substrate 9 are both provided with a primer layer 8, the outer surface of the primer layer 8 is provided with a fireproof layer 7, the outer surface of the fireproof layer 7 is provided with an EVA material layer 3, the outer surface of the EVA material layer 3 is provided with an expanded glass microsphere layer 6, the outer surface of the expanded glass microsphere layer 6 is provided with an outer cold-rolled plate 4, and the outer cold-rolled plate 4 is provided with reinforcing ribs 5. The substrate 9 is The double-layer hot-rolled aluminum-plastic plate utilizes the mechanical principle of the I-beam structure and realizes compounding through high temperature. At the same time, the two layers of aluminum plates are under tension during the whole process. After the forming is cooled, the plate forms a stable internal stress due to the symmetrical contraction of the upper and lower parts, which makes the plate have good rigidity. Compared with the single-layer aluminum plate, the elastic limit is large and it is not easy to deform. The upper and lower surfaces of the substrate 9 are respectively provided with a plurality of recessed grooves 2, and the recessed grooves 2 on both sides are staggered. The recessed grooves 2 are of a "V"-shaped structure. Through the setting of the recessed grooves 2, the surface area of ​​the substrate 9 and its surface complexity are increased, so that the primer layer 8 is in closer contact with the substrate 9, thereby increasing the bite force.

[0024] The material of the outer cold-rolled plate 4 is fluorocarbon color-coated aluminum. The fluorocarbon coating has excellent corrosion resistance, weather resistance, acid rain resistance, salt spray resistance and various air pollutants. In addition, it has good heat resistance and cold resistance, and can resist strong ultraviolet rays. It can remain non-fading and powdery for a long time and has a long service life.

[0025] Adhesive layers are provided between the fireproof layer 7 and the EVA material layer 3 , between the EVA material layer 3 and the expanded glass microsphere layer 6 , and between the expanded glass microsphere layer 6 and the outer cold-rolled plate 4 .

[0026] The aluminum coil 1 has multiple layers inside, and the overall strength is increased. An outer layer of cold-rolled plate 4 is provided on both the upper and lower sides of the innermost substrate 9. This double-layer design plus the double-layer hot-rolled aluminum-plastic plate and the reinforcing ribs 5 further improve the strength. At the same time, it also has the functions that meet the various performance requirements of color-coated aluminum coils, such as water resistance, corrosion resistance, vibration resistance, thermal insulation and sound insulation, etc.

[0027] The adjusting assembly includes a push-pull circular plate 17, an inner rod 11, a spring 15, a clamping column 12, a limit groove 13 and a guide groove 14. The left and right sides of the winding roller 10 are symmetrically provided with a receiving groove 19, and the inner rod 11 corresponding to it is slidably inserted in the receiving groove 19. The ends of the two inner rods 11 away from each other are each provided with a push-pull circular plate 17, and the outer surface of the push-pull circular plate 17 is provided with a vertical plate 18. The outer surface of the inner rod 11 is evenly provided with multiple groups of clamping mechanisms along its length.

[0028] Each set of clamping mechanisms includes two grooves 16 opened on the outer surface of the inner rod 11, and the two grooves 16 are symmetrically distributed on the upper and lower sides of the outer side of the inner rod 11. A clamping column 12 is slidably arranged in the groove 16, and a spring 15 is arranged on the inner bottom wall of the groove 16. The other end of the spring 15 is fixedly connected to the clamping column 12. The end of the clamping column 12 away from the spring 15 is a convex arc surface structure. A limiting groove 13 matching with the clamping column 12 is opened on the inner wall of the accommodating groove 19. A guide groove 14 is opened on the inner wall of the accommodating groove 19 along one side of the circumferential rotation direction of the unwinding of the aluminum coil 1. The guide groove 14 corresponds to the limiting groove 13 one by one, and the limiting groove 13 is connected to the corresponding guide groove 14, and the guide groove 14 is crescent-shaped; specifically, in the spring Under the elastic force of the spring 15, when the clamping column 12 is clamped into the limiting groove 13, the inner rod 11 and the winding roller 10 cannot send lateral relative movement. At this time, the vertical plate 18 is in a vertical state, and when the aluminum coil 1 rotates clockwise to unwind, the winding roller 10 rotates clockwise and drives the inner rod 11 to rotate clockwise. Without the action of external artificial force, the clamping column 12 has no tendency to move toward the guide groove 14. When the length needs to be adjusted, instead of directly pushing and pulling the inner rod 11, the vertical plate 18 is first used to push and pull the circular plate 17 clockwise, thereby driving the inner rod 11 to actively rotate clockwise. In this process, the clamping column 12 is easily separated from the limiting groove 13 with the help of the guide groove 14, and until it is separated from the guide groove 14, as shown in FIG. Figure 5 As shown, at this time, the vertical plate 18 is tilted due to being rotated at a certain angle. Then, the inner rod 11 is pushed and pulled to a suitable position, and the vertical plate 18 is rotated to its original vertical state, so that the clamping column 12 can also return to its original vertical state and be clamped into the new limit groove 13 at this time. If it is not clamped in, just slightly push and pull the position of the inner rod 11 again to ensure that the clamping column 12 is clamped into the adjacent limit groove 13 to complete the adjustment of the overall length. That is, the device can ensure tight clamping and high stability, and can easily release the clamping and adjust the overall length of the device, thereby improving applicability. The operation is simple and convenient, and it is worthy of promotion.
