Description

Technical Field

[0001] The utility model relates to the field of bobbin fixing, in particular to a limiting structure for fixing the top of the uppermost bobbin and a bobbin packaging structure. Background Art

[0002] Glass fiber and basalt yarn bobbins are two raw materials commonly used in the building materials industry. Depending on the specifications and models, they are widely used in industry, agriculture, science and technology and other fields. In order to avoid adverse effects on the products during transportation, the bobbins need to be effectively fixed during transportation to avoid collisions and damage that affect the appearance quality. The bobbin is actually composed of a yarn tube 1 and yarn, and the yarn is wound on the yarn tube 1. The cross-sectional view of the yarn tube 1 is as follows: Figure 1 As shown, the bobbin 1 is composed of a handle 11, a neck 12, a body 13 and a chassis 14, which are fixedly connected in sequence from top to bottom. Usually, the outer diameter of the handle 11 is larger than the neck 12, the outer diameter of the handle 11 is smaller than the inner diameter of the body 13, and the chassis 14 has the same inner diameter as the body 13. During transportation, a yarn cap 2 is usually used in conjunction with the bobbin 1. The cross-sectional structure of the yarn cap 2 is shown in FIG. Figure 2 As shown, a is the inner diameter of the gauze cap 2, b is the outer diameter of the gauze cap 2, and c is the disk diameter of the gauze cap 2, wherein the inner diameter of the gauze cap 2 is slightly larger than the outer diameter of the tube handle 11, and the outer diameter of the gauze cap 2 is slightly smaller than the inner diameter of the tube body 13, so that the tube handle 11 can be inserted into the gauze cap 2; the outer diameter of the gauze cap 2 is slightly smaller than the inner diameter of the tube body 13, so that the gauze cap 2 can be inserted into the tube body 13 of another yarn tube 1.

[0003] The traditional packaging methods are as follows: Figure 3 As shown, a cardboard 3 with a certain number of circular holes is placed in a carton of a certain size. The diameter of the circular holes is the same as the outer diameter a of the yarn caps 2, and the yarn caps 2 are inserted into the circular holes. First, a cardboard 3 with yarn caps 2 is placed at the bottom of the carton. Then, the bobbins are placed into the carton. Each bobbin is inserted with a yarn cap 2, so that the bottom of the bobbin is positioned by the yarn cap 2 at the bottom. After the first layer of bobbins is placed, another cardboard 3 with yarn caps 2 is placed on top of the bobbins. The yarn cap 2 is inserted into the top of the bobbin, so that the top of the bobbin is positioned by the yarn cap 2 at the top. Then the second layer of bobbins is placed. This can be repeated for three or four layers of bobbins. Finally, a cardboard 3 with yarn caps 2 is placed on top of the top layer of bobbins to start packaging.

[0004] However, the use of this structure also has certain problems. The main manifestations are the cardboard 3 and the gauze cap 2 on the top layer. Because there is no bobbin constraint on it, when encountering uneven roads during transportation, the cardboard 3 and the gauze cap 2 will squeeze each other. In serious cases, the gauze cap 2 will fall off the cardboard 3, causing the gauze cap 2 to hit the bobbin, and the bobbins will collide with each other, causing the yarn to rot. To this end, those skilled in the art have solved the above problems by improving the gauze cap 2 structure installed on the cardboard 3 on the top layer. The gauze cap 2 is provided with four small holes on the side, and a strip-shaped plastic clip with a certain elasticity is arranged on the top of the hole to clamp the cardboard 3 and prevent the gauze cap 2 from falling off. This improved gauze cap 2 can still meet the requirements when it is put into use for the first time, but in order to reduce costs, the gauze cap 2 is usually recycled multiple times. Since the gauze cap 2 needs to be used multiple times, this results in not only increasing labor costs by removing the gauze cap 2 from the cardboard 3 and installing it on the cardboard 3, but also causing the gauze cap 2 to break in whole or in part due to the force of the gauze cap 2 clip being separated from the cardboard 3, thereby losing the function of clamping the cardboard 3.

[0005] Therefore, a new solution for fixing the bobbin is needed in the art. Utility Model Content

[0006] The purpose of the utility model is to provide a limiting structure and a bobbin packaging structure for fixing the top of the uppermost bobbin in response to the above-mentioned problems, thereby solving the problem of the uppermost bobbin packaging structure in the current technology, preventing the yarn cap from falling off and damaging the bobbin, and the bobbins from damaging each other.

[0007] The technical solution adopted by the utility model is as follows: a limiting structure for fixing the top of the uppermost tube yarn, including a plate body and a plurality of folding plates that can produce elastic deformation, a plurality of rectangular holes are opened on the plate body, the rectangular holes have a hinged edge and a constrained edge, the folding plates have a connecting edge and a limiting edge, each rectangular hole is connected to a folding plate, and the hinged edge is rotatably connected to the connecting edge, the constraining edge has at least one constraining notch a, and the limiting edge has at least one constraining notch b, the position and quantity of the constraining notch a match the constraint notch b, and the constraint notch a and the constraint notch b at the same position cooperate with each other to embrace the tube neck.

[0008] Furthermore, the plate body and the folding plate are both made of cardboard, and the plate body and the folding plate are an integrated structure, and the hinged edges and the connecting edges are the folds of the folding plate.

[0009] Furthermore, the constraining side is the long side of the rectangular hole, and the plurality of constraining notches a are arrayed along the constraining side; the limiting side is the long side of the folded plate, and the plurality of constraining notches b are arrayed along the limiting side.

[0010] Furthermore, the plurality of rectangular holes are arrayed along a direction perpendicular to the constraint edge.

[0011] Furthermore, the constraint edge is parallel to the hinge edge; the restriction edge is parallel to the connection edge.

[0012] Furthermore, the constraint notch a and the constraint notch b at the same position can be assembled into a circular hole, and the diameter of the circular hole matches the outer diameter of the tube neck.

[0013] A bobbin packaging structure comprises a top-layer constraint plate and multiple other-layer constraint plates arranged sequentially from top to bottom. The top-layer constraint plate serves as the limiting structure for securing the top of the topmost bobbin. The other-layer constraint plates each have multiple through-holes, each containing a yarn cap. The through-holes on each of the other-layer constraint plates are positioned in the same manner as the constraint notches a and / or constraint notches b on the top-layer constraint plate.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0015] 1. The top constraint plate of the present invention does not have a gauze cap, and the gauze caps used by the other constraint plates can be reused, thus saving gauze caps, reducing costs and increasing efficiency;

[0016] 2. The top restraining plate of the utility model does not have a yarn cap. By combining the restraining notches a and b with the clamping tube neck and using the tube handle to restrain the folding plate, the topmost bobbin is effectively positioned and restrained, preventing the bobbins from colliding with each other and being damaged during transportation.

[0017] 3. The top restraining plate of the present invention does not have a yarn cap, and there is no phenomenon that the yarn cap falls off and causes the yarn cap to damage the bobbin. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Furthermore, the use of terms such as "horizontal" and "vertical" in this specification does not necessarily imply that a component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply refers to a direction that is more horizontal than "vertical," and does not imply that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0027] In the description of this specification, it should also be noted that, unless otherwise clearly stipulated and limited, the terms "setting", "installation", "connection" and "connection" should be understood in a broad sense. For example, the connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection between the internal parts of two components.

[0028] Example 1

[0029] like Figure 4-Figure 5 As shown, a limiting structure for fixing the top of the uppermost tube yarn includes a plate body 4 and multiple folding plates 5. The folding plates 5 can produce elastic deformation, so that the restraining notches a41 and the restraining notches b51 cooperate with each other to clamp the tube neck 12, and the folding plates 5 are clamped into the position of the tube neck 12; a plurality of rectangular holes 43 are opened on the plate body 4, and the rectangular holes 43 have a hinged edge 44 and a restraining edge 42. The folding plates 5 have a connecting edge 53 and a limiting edge 52. Each rectangular hole 43 is connected to a folding plate 5, and the hinged edge 44 is rotatably connected to the connecting edge 53, that is, the folding plates 5 can rotate around the hinged edge 44, providing a basis for clamping into the tube neck 12; the restraining edge 42 has at least one restraining notch a41, and the limiting edge 52 has at least one restraining notch b51. The position and number of the restraining notches a41 and b51 match each other, and the restraining notches a41 and b51 at the same position cooperate with each other to encircle the tube neck 12.

[0030] In this embodiment, by cooperating with the clamp tube neck 12 through the constraint notch a41 and the constraint notch b51, and utilizing the tube handle 11 to constrain the folding plate 5, the positioning and constraint of the topmost tube yarn are effectively achieved, thereby preventing the tube yarns from colliding with each other and being damaged during transportation; the top constraint plate does not have a yarn cap 2, and the yarn caps 2 used by the other layers of constraint plates can be reused, thereby saving yarn caps 2, reducing costs and increasing efficiency; the top constraint plate does not have a yarn cap 2, and there is no phenomenon of the yarn cap 2 falling off and damaging the tube yarn.

[0031] In this embodiment, the size of the folding plate 5 can be the same as the size of the rectangular hole 43, or it can be smaller than the size of the rectangular hole 43, as long as the constraint notch a41 and the constraint notch b51 cooperate with each other to embrace the tube neck 12, and the folding plate 5 is constrained by the tube handle 11 and will not separate from the tube neck 12; preferably, the size of the folding plate 5 matches the size of the rectangular hole 43.

[0032] It should be noted that the size of the rectangular hole 43 needs to be larger than the outer diameter of the tube handle 11 to ensure that the tube handle 11 can effectively pass through the rectangular hole 43 , providing a basis for constraining the notch a41 to embrace the tube neck 12 .

[0033] Example 2

[0034] Based on Example 1, a feasible specific implementation method is further proposed.

[0035] A feasible implementation method is that the plate body 4 and the folding plate 5 are both cardboard 3, and the plate body 4 and the folding plate 5 are an integrated structure, the hinged edge 44 and the connecting edge 53 are the folds of the folding plate 5, and the folding plate 5 can rotate along the folds; and the cardboard 3 can be bent to produce elastic deformation, and the folding plate 5 can also be stuck into the tube neck 12.

[0036] A feasible implementation method is that when the bobbin is constrained by the limiting structure during transportation, the bobbin will give the limiting structure a reaction force. For this purpose, the constraining edge 42 is the long side of the rectangular hole 43, and multiple constraining notches a41 are arrayed along the constraining edge 42; the limiting edge 52 is the long side of the folding plate 5, and multiple constraining notches b51 are arrayed along the limiting edge 52; multiple rectangular holes 43 are arrayed in a direction perpendicular to the constraining edge 42; so that the constraining force on the plate body 4 and the folding plate 5 is evenly distributed, avoiding local deformation caused by concentrated force on the plate body 4 and the folding plate 5, especially when the plate body 4 and the folding plate 5 are cardboard 3, the occurrence of concentrated force should be avoided.

[0037] In a feasible implementation manner, the constraining edge 42 is parallel to the hinged edge 44 ; the limiting edge 52 is parallel to the connecting edge 53 , so that both parallel edges of the folding plate 5 can be constrained, thereby improving the stability of the folding plate 5 when it is inserted into the tube neck 12 .

[0038] In a feasible implementation manner, the constraint notch a41 and the constraint notch b51 at the same position can be assembled into a circular hole, the diameter of which matches the outer diameter of the tube neck 12 and can completely surround the tube neck 12 without any gap, thereby improving stability.

[0039] Example 3

[0040] A tube yarn packaging structure includes a top-level constraint plate and multiple other-level constraint plates arranged in sequence from top to bottom, the top-level constraint plate is a limiting structure for fixing the top of the topmost tube yarn as described in any one of the embodiments 1-2; the other-level constraint plates have multiple through holes, each of which has a yarn cap 2; the through holes on each of the other-level constraint plates are positioned in the same manner as the constraint notches a41 and / or constraint notches b51 of the top-level constraint plate; the detailed tube yarn packaging process is combined with the process described in the background technology, and only the cardboard 3 fixing the top of the topmost tube yarn is replaced with the limiting structure.

[0041] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
