Description

Technical Field

[0001] The present invention relates to the technical field of copper coil packaging, and particularly relates to a packaging paper pad for copper coils. Background Art

[0002] The most common winding and unwinding method for copper coils is the external extraction type. The external extraction type copper coils are generally packaged in the form of a wooden disk, a paper pad, a copper coil, a paper inner lining, a paper pad, and a wooden disk from bottom to top in sequence. When using the external extraction type copper coils, a clamp is used to hold the wooden disk, and the copper coil is unwound by the rotation of a motor. In the traditional technology, when the clamp holds the wooden disk, due to the shrinkage of the middle part of the wooden disk under stress, the outer side of the wooden disk expands outward, and the packaging paper pad cannot be effectively pressed, resulting in an increase in the gap between the copper pipe, the paper pad, and the wooden disk; the loose paper pad becomes even looser during rotation and may even rotate relative to the copper coil, causing the paper pad to crack or fall off, and the copper coil cannot be effectively protected, resulting in material jamming. Therefore, it is necessary to design a packaging paper pad to avoid the loosening of the paper pad and the relative rotation between the copper coil and the paper pad. Summary of the Invention

[0003] Aiming at the above problems existing in the prior art, the present invention provides an external extraction type copper coil packaging paper pad with a simple structure and no material jamming.

[0004] The present invention solves its technical problems by adopting the following technical solutions:

[0005] A packaging paper pad for copper coils, whose shape is the same as that of the bottom wooden disk. It is characterized in that a circular connection hole for fixing a clamp is formed in the middle of the paper pad, and fixing holes are evenly distributed around the connection hole. Protrusions matching the fixing holes are arranged at the corresponding positions of the wooden disk, and the thickness of the protrusions is greater than the thickness of the paper pad; strip-shaped grooves are also arranged on the paper pad.

[0006] Further, there are multiple fixing holes, and the multiple fixing holes are centrosymmetric about the center of the paper pad, and the multiple fixing holes are fan-shaped, and the trajectory connected by the arcs of the fan is circular.

[0007] Further, the fixing holes are right-angled fans, so that a pair of right-angled sides of two adjacent right-angled fans are parallel, and the other pair of right-angled sides are on a straight line.

[0008] Further, the strip-shaped grooves extend from the edge of the paper pad towards the circular direction, and the two ends of the strip-shaped grooves are not open.

[0009] Further, two of the strip-shaped grooves are on a straight line.

[0010] Further, the fixing holes are arranged on both sides of the strip-shaped grooves, and the length of the strip-shaped grooves is the same as the thickness of the copper coil.

[0011] Further, the edge of the strip-shaped groove on the side closer to the center of the paper pad coincides with the arc of the circular trajectory formed by the fixing hole.

[0012] Further, the circular trajectory formed by the fixing hole is consistent with the inner diameter of the copper coiled pipe.

[0013] Further, a limiting hole for limiting is provided in the middle of the wooden disk bump.

[0014] The copper coiled pipe packaging paper pad of the present invention has the following beneficial technical effects compared with the prior art:

[0015] In the present invention, the bump on the wooden disk cooperates with the fixing hole on the paper pad, and the bump passes through the fixing hole. There is no relative movement between the wooden disk and the paper pad. In addition, after the limiting holes on the wooden disk are connected with connecting lines, the wooden disk and the paper pad are better fixed together. No matter how the wooden disk is stressed, the wooden disk can effectively press the paper pad, and there will be no phenomenon of paper pad movement or detachment, effectively protecting the copper pipe. The structure of the present invention is simple, easy to operate, does not increase the packaging operation process, is firm and wear-resistant, and preferably solves the problem that the paper pad is easy to loosen after the middle part of the wooden disk is stressed, resulting in cracking or detachment of the paper pad and causing material jamming, reduces the failure rate, improves the production efficiency, and realizes continuous wire laying.

[0019] The technical solution of the present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be understood that the following embodiments are only for illustrative and explanatory purposes of the present invention, and should not be construed as limiting the protection scope of the present invention. All technologies implemented based on the above content of the present invention are covered within the scope of protection intended by the present invention.

[0020] Referring to the drawings, a copper coiled pipe packaging paper pad has the same shape and size as the shape of the bottom wooden disk 5. A circular connecting hole 2 for fixing a fixture is formed in the middle of the paper pad 4, and fixing holes 1 are evenly distributed around the connecting hole 2. Bumps 9 matching the fixing holes 1 are provided at the relative positions of the wooden disk 5, and the thickness of the bumps 9 is greater than the thickness of the paper pad 4; a strip-shaped groove 3 is also provided on the paper pad 4.

[0021] The shape of the paper gasket 4 is basically the same as that of the wooden tray 5. After being clamped at the center of the wooden tray 5, the central part of the paper gasket 4 is also clamped. The bump 9 on the wooden tray 5 passes through the fixing hole 1 on the paper gasket, preventing the paper gasket from moving. At the same time, a paper inner lining 7 is detachably arranged inside the copper coil tube 6 and closely attached to the copper coil tube 6. The two ends of the paper inner lining 7 are respectively connected to the paper gasket 4. The paper inner lining 7 plays a supporting role for the paper gasket, making the paper gasket not loose. In addition, the bump 9 formed on the wooden tray increases the thickness of the wooden tray. When the middle part of the wooden tray is clamped, it reduces the amplitude of the shrinkage deformation of the wooden tray under stress, reduces the gap between the copper coil tube 6, the paper gasket 4 and the wooden tray 5, and reduces the occurrence of material jamming. The connecting hole 2 in the middle of the paper gasket is the same in position and size as the through hole in the middle of the wooden tray, which is used to fix the fixture and is convenient for clamping.

[0022] There are multiple fixing holes 1. The multiple fixing holes 1 are centrosymmetric about the center of the paper gasket, and the multiple fixing holes 1 are fan-shaped. The trajectory connected by the arcs of the fan is circular. Designing the trajectory formed by arranging the multiple fixing holes 1 to be the same as the inner diameter of the copper coil tube 6 not only facilitates better positioning during packaging, making the copper coil tube located at the center of the wooden tray and the paper gasket during packaging, making the pressure received by the wooden tray and the paper gasket uniform, making the paper gasket not easily damaged, and better protecting the copper coil tube, but also the symmetric hollow structure increases the strength of the paper gasket, making the paper gasket not break during use.

[0023] The fixing hole 1 is a right-angled fan shape, such that a pair of right-angled sides of two adjacent right-angled fans are parallel, and the other pair of right-angled sides are on a straight line. There are four fixing holes 1, and the distances between the four fixing holes 1 are equally spaced. The four fixing holes 1 form a ⊕ shape on the paper gasket, with a more solid structure, better fixing and packaging effects. The right-angled fan-shaped structure is not only convenient for processing, but also makes it easier for the bump 9 on the wooden tray to match it. The structure is simple and convenient for processing.

[0024] The strip-shaped groove 3 extends from the edge of the paper gasket towards the circular direction, and the two ends of the strip-shaped groove 3 are not open. The strip-shaped groove 3 is mainly used to be in the same position as the binding rope when binding the copper coil tube, preventing the copper coil tube 6 from not being in close contact with the paper gasket 4 due to the presence of the binding rope, and making the copper coil tube easy to loosen during use, resulting in material jamming.

[0025] In order to increase the fixing effect on the copper coil tube 6, two strip-shaped grooves 3 are on a straight line.

[0026] In order to enhance the fixing effect on the copper coil pipe, the fixing holes 1 are arranged on both sides of the strip-shaped groove 3, and the length of the strip-shaped groove 3 is consistent with the thickness of the copper coil pipe. If the length of the strip-shaped groove 3 is too long, the strength of the paper gasket will be reduced and it is easy to break, especially easy to break at the strip-shaped groove 3; if the length of the strip-shaped groove 3 is too short, the significance of the strip-shaped groove 3 will not exist, which will also affect the contact between the copper coil pipe and the paper gasket and is likely to cause the copper coil pipe to loosen. Therefore, in the present invention, the length of the strip-shaped groove 3 is designed to be consistent with the thickness of the copper coil pipe, which can better bundle and package the copper coil pipe while maximizing the strength of the paper gasket.

[0027] The edge of the strip-shaped groove 3 close to the center of the paper gasket coincides with the arc of the circular trajectory formed by the fixing holes 1. The circular trajectory formed by the fixing holes 1 is consistent with the inner diameter of the copper coil pipe 6, so that all the fixing holes 1 are located within the hollow ring formed by the inner diameter of the copper coil pipe, and the strip-shaped groove 3 is entirely arranged to coincide with the copper coil pipe. The advantage of this setting is that the fixing holes 1 cooperate with the convex blocks 9 on the wooden tray for limiting, which is convenient for accurate positioning during packaging so that the copper coil pipe is located in the middle of the wooden tray. At the same time, the cross-shaped connection design formed between the fixing holes 1 improves the strength of the paper gasket, and the paper gasket will not displace during use, and the copper coil pipe is not easy to loosen. The position of the paper lining 7 just coincides with the arc of the circular trajectory formed by the fixing holes 1, playing a supporting role.

[0028] A limiting hole 8 for limiting is arranged in the middle of the convex block 9 of the wooden tray. During packaging, the limiting holes 8 on two adjacent convex blocks 9 are connected by a rope with the opposite limiting holes 8. On the one hand, the copper coil pipes between the wooden trays are firmly fixed between the paper gaskets to prevent sliding. On the other hand, it limits between the wooden tray, the paper gasket and the copper coil pipe. The wooden tray and the paper gasket are fixed together by a rope, and the copper coil pipe is limited by the ropes on the opposite sides to prevent the copper coil pipe from sliding relative to the paper gasket and the wooden tray during transportation and use, affecting the use.

[0029] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art of this technology, any modifications, equivalent replacements, improvements, etc. made without departing from the technical concept of the present invention should be included in the protection scope of the present invention.
